Description

  The present invention relates to a transmission module that transmits information related to an information processing apparatus along a predetermined transmission path including the information processing apparatus, and a network system including the transmission module and the information processing apparatus.

  Conventionally, by using a sensor module that measures environmental parameters such as temperature and humidity, and transmitting the measured information to an information processing device via a network, a large amount of measurement data can be easily collected. Technologies that enable it are being developed. In this case, the wireless function for transmitting the measured information is formed by providing the sensor module with a wireless function. Here, regarding a wireless network, for example, Patent Literature 1 relates to data transmission between a base station and a mobile phone terminal. When a data retransmission request is received due to a communication failure, the data is divided into small pieces, and the success rate of data transmission. A technique for improving the above is disclosed. In particular, the success rate can be improved by dividing the data into smaller pieces as the communication quality is worse (as the degree of communication deterioration is larger).

  Further, for example, in Patent Document 2, regarding data transmission between a sensor terminal and a relay station, measurement data measured by a sensor included in transmitted data and data related to communication quality according to the degree of communication failure. A technique is disclosed that adjusts the ratio of (for example, RSSI, the number of retransmissions, latency, etc.) to achieve both the collection of measurement data necessary for the network and the data collection necessary for maintaining communication quality on the network. In this technique, the ratio is adjusted by allocating a margin of data capacity generated by deleting a part of measurement data to data related to communication quality.

  From a viewpoint of information collection, it is preferable to transmit more information in a network including one or a plurality of transmission modules functioning as a repeater and leading to an information processing apparatus. In particular, when the transmission module transmits information from the upstream side, collecting information to be transmitted including predetermined information in the transmission module enables more efficient information collection, The amount of information to be transmitted will increase.

  When the amount of information to be transmitted increases in this way, particularly when information transmission is performed by wireless communication, information transmission may not be performed well due to external factors such as external noise. Even if information transmission is performed again when such transmission fails, it is difficult to realize smooth information transmission unless the transmission environment is improved if the transmission information capacity remains large. It will be. Moreover, it is preferable to suppress the processing amount applied to the repeater as much as possible not only from the viewpoint of information transmission but also from the viewpoint of the processing capability of the transmission module and the capacity of the supplied power. In order to collect information in the information processing apparatus via the transmission module in this way, it is necessary to appropriately determine what state the transmission module is placed in, formation of information to be transmitted according to the state, and There is a need to perform such transmission.

  The present invention has been made in view of such problems, and in a network reaching an information processing apparatus formed by a plurality of transmission modules as repeaters, without excessively increasing the amount of information flowing through the network, An object is to suitably transmit information necessary for the information processing apparatus.

  In the present invention, in order to solve the above-mentioned problem, in a transmission module that transmits information processed by an information processing apparatus (hereinafter referred to as “predetermined transmission information”) along a predetermined transmission path, the information is determined by itself. When including information in the information received from the upstream transmission module, it is determined whether or not the state in which the user is placed should express the predetermined information in the form of summary information with a small capacity, A configuration is adopted in which the summary information is included in the information from the upstream side according to the determination result. Thereby, the capacity of information to be transmitted can be suppressed, and various problems caused by the increase in the capacity of information can be solved while transmitting a necessary amount of information to the information processing apparatus. In the present application, “self-transmission module” is an expression used to specify a transmission module included in a network. That is, when a transmission module belonging to a network is specified as a reference, the transmission module is expressed as “self transmission module”. Also, in the information flow in the network with reference to the self-transmission module, the transmission module located on the upstream side is referred to as “upstream transmission module” or similar expression, and the transmission module located on the downstream side is referred to as “downstream transmission module” or An expression similar to that. Therefore, expressions such as “self-transmission module”, “upstream transmission module”, and “downstream transmission module” are based on the relative relationship between the transmission modules. The transmission module specified as the transmission module is also different. In addition, when there is no need to distinguish between “self-transmission module”, “upstream transmission module”, “downstream transmission module”, and the like, they may be simply expressed as “transmission module”.

  Specifically, the present invention is a module that transmits predetermined transmission information to be processed by the information processing apparatus along a predetermined transmission path including the information processing apparatus, and the transmission module includes the predetermined transmission information. Receiving means for receiving the predetermined transmission information as upstream information from an upstream transmission module located upstream of the self-transmission module in the path; and a downstream transmission module located downstream of the self-transmission module in the predetermined transmission path The predetermined information in the self-transmission module, which is information to be transmitted to the network, is information that can be understood by the information processing apparatus as information related to the upstream information and the predetermined information, and its capacity is reduced. Determining means for determining whether or not the self-transmission module is placed in a predetermined state to be expressed in the form of the summarized information; When the determination means determines that the self-transmission module is placed in the predetermined state, the summary information is included as new predetermined transmission information in the self-transmission module instead of the predetermined information in the self-transmission module. Forming means, and transmitting means for transmitting new predetermined transmission information formed by the forming means to the downstream transmission module.

In the transmission module according to the present invention, the reception unit receives predetermined transmission information from the upstream transmission module as upstream information, and transmits information related to the self-transmission module and to be transmitted to the information processing apparatus. The predetermined transmission information is transmitted to the downstream transmission module by the transmission means. Thereby, the transmission module performs information collection and relay processing in the network, and efficient information collection is possible via the network formed by the transmission modules arranged in a distributed manner. The content of the predetermined information in the self-transmission module is not particularly limited. However, according to the gist of the present invention, the predetermined information is information to be transmitted to the information processing apparatus via the downstream transmission module. . In addition, the predetermined transmission path is formed by a transmission module as a repeater located between the starting point and the end point, and both points. In the present invention, the predetermined transmission path is a specific transmission path. There is no intention to be limited to a route. That is, the predetermined transmission path may be a predetermined path, or when the transmission module that has received the information transmits information to the downstream transmission module, the information transmission environment is changed. The route may be determined at any time in consideration. Further, the transmission of information by the receiving means and the transmitting means may be a wireless transmission or a wired transmission.

  Here, the predetermined transmission information transmitted by the transmission module is information to be processed by the information processing device included in the predetermined transmission path. In the present invention, the processing form of the predetermined transmission information in the information processing apparatus is not limited to a specific form. The predetermined transmission information received from the upstream transmission module, that is, the upstream information includes predetermined information in the transmission module that has transmitted the predetermined information. The addition of the predetermined information by the transmission module does not have to be performed by all the transmission modules belonging to the network, and it is sufficient that the predetermined information in each transmission module is added by at least a plurality of transmission modules. Further, the addition of the predetermined information by the transmission module may be performed by a transmission module in which relaying is continuous, or may be performed by a transmission module that is not continuous.

  Here, in the transmission module according to the present invention, the determination means determines whether or not the self-transmission module is placed in a predetermined state in which the predetermined information and upstream information are to be expressed in the form of summary information. . That is, if the predetermined information in the self-transmission module is included as it is in the upstream information, the capacity of the final predetermined transmission information increases. This increase in capacity hinders efficient information collection, and may cause transmission problems such as transmission failures and problems such as an increase in the load on a transmission module that performs relay processing on the downstream side. Even if such a problem does not occur, smooth information transmission can be promoted by reducing the capacity of the predetermined transmission information. Therefore, when the self-transmission module may cause a problem due to such an increase in the capacity of the predetermined transmission information or when smoother information transmission is required, the determination means reduces the capacity. It is determined that the predetermined information in the self-transmission module is in a predetermined state that needs to be expressed in the form of summary information. In other words, from the viewpoint of information collection, it is considered that the predetermined information processing on the information processing apparatus side can be suitably executed by transmitting the predetermined information in the self-transmission module as it is. In order to achieve a balance between the processing result (for example, processing accuracy) and the maintenance of smooth information transmission, the determination processing by the determination means is performed.

  If the determination unit determines that the self-transmission module is in a predetermined state, the forming unit associates the upstream information and the self-transmission module with the predetermined information and has a relatively small summary. Information is formed, and new predetermined transmission information in the self-transmission module including the summary information is formed. If the determination means determines that the self-transmission module is not in a predetermined state, it means that it is less necessary to reduce the capacity of the predetermined transmission information. The predetermined information in the self-transmission module may be added to the upstream information to form new predetermined transmission information. The new predetermined transmission information thus formed in the self transmission module is transmitted to the downstream transmission module by the transmission means.

  In this way, by the determination of the determination means, the state where the self-transmission module is placed is grasped, and new predetermined transmission information including summary information is formed by the formation means based on the determination result, so that the self-transmission module Thus, it is possible to favorably balance the information processing result in the information processing apparatus and the maintenance of smooth information transmission.

Here, in the transmission module, the determination unit compares the predetermined information in the self-transmission module with upstream predetermined information that is included in the upstream information and can be compared with the predetermined information. It may be determined whether or not the self-transmission module is placed in the predetermined state that has a predetermined identical relationship with the upstream predetermined information. That is, the predetermined information in the self-transmission module and the predetermined information included in the predetermined transmission information in the upstream transmission module, and can be almost identified with the upstream predetermined information that can be compared with the predetermined information in the self-transmission module. If a predetermined identical relationship that has only a certain degree of difference is established, the predetermined information in the self-transmission module to be newly included can be used as summary information for the predetermined information processing on the information processing apparatus side. The effect is considered to be small. Therefore, in such a case, even if the self-transmission module is determined to be in the predetermined state and the summary information is included by the forming unit to reduce the capacity of the predetermined transmission information, Smooth information transmission can be realized while suitably maintaining predetermined information processing.

  The predetermined identical relationship is a relationship in which the predetermined information in the self-transmission module is the same as the upstream predetermined information, or a difference between the predetermined information and the upstream predetermined information is within a predetermined range. There may be. These relationships are merely examples, and even if the relationship is other than this, if it is possible to realize smooth information transmission while suitably maintaining predetermined information processing on the information processing device side, this application It can be adopted as a predetermined identical relationship according to the invention.

  Here, when the predetermined identical relationship described above is established between the predetermined information in the self-transmission module and the upstream predetermined information, the summary information includes the predetermined information in the self-transmission module as the upstream predetermined information. On the other hand, it may be symbol information which means the predetermined same relationship. By employing the symbol information, the information processing apparatus can accurately recognize the predetermined information in the self-transmission module with a smaller capacity. As the symbol information, so-called flag information, information by a specific character string meaning a predetermined identical relationship, other specific information understandable on the information processing apparatus side, or the like can be adopted.

  Further, in the transmission module up to the above, when the predetermined information and the summary information in the self-transmission module are not included in the predetermined transmission information, the predetermined information in the self-transmission module in the information processing apparatus It may be configured to be understood to be in the same predetermined relationship with the side predetermined information. When the predetermined identical relationship described above is established between the predetermined information and the upstream predetermined information in the self-transmission module, the forming unit causes the determination unit to place the self-transmission module in the predetermined state. When it is determined that the upstream transmission side information is determined, the upstream information is directly formed as new predetermined transmission information in the self transmission module, that is, the inclusion of the predetermined information in the self transmission module in the new predetermined transmission information may be omitted. . Thereby, the capacity | capacitance of new predetermined transmission information can be reduced as much as possible.

  Furthermore, the timing at which the determination process by the determination unit is performed will be described below. 1stly, the said determination means is the said downstream of the new predetermined transmission information formed by including the said predetermined information in a self-transmission module in the said predetermined transmission information from the said upstream transmission module received by the said receiving means. When transmission to the side transmission module fails, it may be determined that the self-transmission module is placed in the predetermined state in which the predetermined information is to be expressed in the form of the summary information. A possible cause of the failure in transmitting the predetermined transmission information to the downstream transmission module is that the capacity of the predetermined transmission information is excessive. Therefore, when transmission of the predetermined transmission information fails and a retry is performed, the determination unit determines that the self-transmission module is placed in a predetermined state, so that a new predetermined transmission using the summary information by the forming unit is performed. Information is formed, and information transmission can be led to success.

Second, the determination means self-transmits the predetermined transmission information from the upstream transmission module temporarily received by the receiving means based on the past transmission result from the self-transmission module to the downstream transmission module. When new predetermined transmission information formed including the predetermined information in the module is transmitted to the downstream transmission module, the predetermined information is expressed in the form of the summary information when the transmission is predicted to fail. It may be determined that the self-transmission module is placed in the predetermined state. When the transmission of the predetermined transmission information is predicted to fail based on the past transmission result, the self-transmission module is in a predetermined state so that new predetermined transmission information is formed using the summary information by the forming unit. Therefore, it is possible to avoid a transmission failure due to an increase in the capacity of the predetermined transmission information.

  Thirdly, the determination process by the determination unit may be performed based on the capacity of the predetermined information in the self-transmission module. For example, the determination means is configured such that when the capacity of the predetermined information in the self-transmission module exceeds a predetermined capacity, the self-transmission module is placed in the predetermined state in which the predetermined information is to be expressed in the form of the summary information. It may be determined that With this configuration, it is possible to solve the problem caused by the increase in the capacity of the predetermined transmission information.

  Fourthly, the determination means determines whether the predetermined information in the self-transmission module is in the form of the summary information based on the state of power supplied to the downstream transmission module or the processing capability of the downstream transmission module. It may be determined whether or not the self-transmission module is placed in a predetermined state to be expressed by An increase in the capacity of the predetermined transmission information can affect the processing performance in the downstream transmission module. For example, since the amount of processing in the downstream transmission module increases due to an increase in the capacity of the predetermined transmission information, there is a possibility that the time required for the processing will be prolonged and the power consumption may be increased. Therefore, in order to reduce the processing load of such a downstream transmission module, it is considered useful to form new predetermined transmission information including summary information. Therefore, as described above, the determination means supplies the downstream transmission module. It is preferable to make a determination based on the state of power or the processing capability of the downstream transmission module.

  Here, in the transmission module up to the above, the predetermined information in the self transmission module, the reception time information when the self transmission module received the predetermined transmission information from the upstream transmission module, and the predetermined transmission to the downstream transmission module. Transmission time information for transmitting information may be included, in which case, the forming means summarizes the difference between the transmission time of the upstream transmission module and the reception time of the self-transmission module included in the upstream information. The information may be formed as the new predetermined transmission information including the summary information and the transmission time information of the self-transmission module.

  When the reception time information and transmission time information of the self-transmission module are useful as information reflecting the processing state of the self-transmission module or the upstream transmission module or the downstream transmission module existing upstream and downstream of the transmission of the predetermined transmission information. There is. Therefore, by including these time information as predetermined information in the self-transmission module, it is possible to effectively execute predetermined information processing on the information processing apparatus side. However, in this case, the capacity of the predetermined information in the self-transmission module increases depending on the capacity of the time information. In particular, when high-accuracy time information is required on the information processing apparatus side, problems due to an increase in the capacity tend to occur. Based on such points, information on the transmission time between modules, which is the difference between the transmission time of the upstream transmission module and the reception time of the self-transmission module included in the upstream information, that is, the time required for transmission between the transmission modules. Is expressed in the form of summary information. By taking the difference, it is possible to obtain summary information that appropriately represents the correlation between the reception time and the transmission time, while greatly reducing the information capacity. Then, by transmitting new predetermined transmission information including the summary information and the transmission time information of the self-transmission module to the information processing apparatus side, the information processing apparatus can also grasp the reception time of the self-transmission module. Become.

  Further, as another method for including the time information in the predetermined information, the following method may be used. That is, in the transmission module described above, the predetermined information in the self-transmission module includes the reception time information when the self-transmission module receives the predetermined transmission information from the upstream transmission module, and the predetermined transmission information to the downstream transmission module. Transmission time information may be included. In this case, the forming means uses the difference between the reception time of the self-transmission module and the transmission time of the self-transmission module as the summary information, and the summary information and the self-transmission module May be formed as the new predetermined transmission information including the reception time information or the transmission time information. The difference between the reception time of the self-transmission module and the transmission time of the self-transmission module, that is, information regarding the processing time in the module, which is the time required for processing in the self-transmission module, is expressed in the form of summary information. By taking the difference, it is possible to obtain summary information that appropriately expresses the correlation between the reception time and the transmission time in the self-transmission module while greatly reducing the information capacity. Then, by transmitting this summary information and new predetermined transmission information including the reception time information or transmission time information of the self-transmission module to the information processing apparatus side, the information processing apparatus receives the reception time and transmission of the self-transmission module. Any time can be grasped.

  The present invention can also be understood from the aspect of a network system configured to transmit predetermined transmission information to be processed by the information processing apparatus along a predetermined transmission path including the information processing apparatus. In this case, at least one transmission module of the plurality of transmission modules receives the predetermined transmission information as upstream information from an upstream transmission module located upstream of the own transmission module in the predetermined transmission path. And the predetermined information in the self-transmission module, which is information to be transmitted to the downstream transmission module located on the downstream side of the self-transmission module in the predetermined transmission path, is the upstream information and the predetermined information in the information processing apparatus. Judgment to determine whether the self-transmission module is placed in a predetermined state that is understandable information associated with the information and should be expressed in the form of summary information with reduced capacity And when the determination means determines that the self-transmission module is placed in the predetermined state. Forming means for forming the new predetermined transmission information in the self-transmission module including the summary information instead of the predetermined information in the self-transmission module, and the new predetermined transmission information formed by the forming means in the downstream transmission Transmitting means for transmitting to the module. It should be noted that the technical idea disclosed regarding the invention of the transmission module can be applied to the invention of the information transmission network system as long as there is no technical flaw.

In this case, the method includes a reception step of receiving the predetermined transmission information as upstream information from an upstream transmission module located upstream of the self-transmission module in the predetermined transmission path; and a self-transmission in the predetermined transmission path. Understand that the predetermined information in the self-transmission module, which is information to be transmitted to the downstream transmission module located downstream of the module, is the information associated with the upstream information and the predetermined information in the information processing apparatus. A determination step for determining whether or not the self-transmission module is placed in a predetermined state that is possible information and should be expressed in the form of summary information with reduced capacity; and the self-transmission module in the determination step Is determined to be in the predetermined state, the predetermined information in the self-transmission module is substituted for the predetermined information. Forming a new predetermined transmission information in the self-transmission module including the summary information, and a transmission step for transmitting the new predetermined transmission information formed in the formation step to the downstream transmission module. Including. It should be noted that the technical idea disclosed regarding the invention of the transmission module can be applied to the invention of the information transmission method as long as there is no technical flaw.

According to another aspect of the present invention, there is provided an information transmission program that causes a transmission module that transmits predetermined transmission information to be processed by an information processing device along a predetermined transmission path including the information processing device to execute processing including the following steps. It can also be seen from the side.

It is a functional block diagram of the transmission module contained in the network system shown in FIG. It is a functional block diagram of the server contained in the network system shown in FIG.

It is a flowchart of the 2nd information transmission process which transmits the transmission information performed with the transmission module shown in FIG. It is a figure which shows three forms which transmit the transmission time information and transmission time information in a transmission module as transmission information.

  A network system 10 (hereinafter also simply referred to as “system”) 10 according to the present invention and transmission modules 2 and 3 included in the system will be described with reference to the drawings. The configuration of the following embodiment is an exemplification, and the present invention is not limited to the configuration of this embodiment.

FIG. 1 is a diagram showing a schematic configuration of the system 10. In the system 10, two transmission paths are formed between each of the transmission modules equipped with sensors for measuring various external environment parameters (temperature, humidity, acceleration, etc.) and the information processing apparatus 1. The same reference numerals are assigned to the transmission modules included in one transmission path. In addition, when a plurality of transmission modules in one transmission path are distinguished from each other, letters (“A”, “B”, etc.) for identifying the individual are provided after the reference numbers 2 and 3 of the transmission modules. Will be attached.

  Specifically, in the system 10, a transmission path including a plurality of transmission modules 2 and a transmission path including a plurality of transmission modules 3 are formed. The former transmission path includes the transmission modules 2A to 2C on which the sensor is mounted, and the latter transmission path includes the transmission modules 3A and 3B on which the sensor is mounted and only the relay function without the sensor. A transmission module 3 </ b> C is included. In the system 10 shown in FIG. 1, communication between transmission modules is performed in a wireless format, and the relay order of the transmission modules in each transmission path is determined in advance. Therefore, for example, in the transmission path including the transmission module 2, measurement data from the sensors mounted on each transmission module is sequentially transmitted in the order of the transmission modules 2A, 2B, and 2C, and finally transmitted from the transmission module 2C. It is to be transmitted to the information processing apparatus 1 that is the destination of the route. In addition, in the transmission path including the transmission module 3, measurement data from the sensors mounted on the transmission modules are sequentially transmitted in the order of the transmission modules 3A and 3B, and finally the transmission module 3C is transmitted from the transmission module 3B. The transmitted transmission information is to be relayed to the information processing apparatus 1 that is the destination of the route. The transmission information according to the present embodiment corresponds to the predetermined transmission information of the present invention, and is a general term for information transmitted to the information processing apparatus 1 along each transmission path. And the measurement data by the sensor mounted in each transmission module is included in the transmission information.

  Here, the information processing apparatus 1 includes a transmission / reception apparatus 1a and a server 1b. The transmission / reception device 1a receives information transmitted from the transmission modules 2C and 3C located closest to the information processing device 1 in each transmission path, and sends a predetermined operation command to the transmission module located in each transmission path. It is a device for transmitting to the transmission modules 2C, 3C for delivery. The transmission / reception device 1a is electrically connected to the server 1b. The server 1b collects information measured by sensors mounted on the transmission modules 2A to 2C and the transmission modules 3A and 3B, for example, and performs predetermined information processing.

  In addition, measurement by the sensors mounted on the transmission modules 2A to 2C and the transmission modules 3A and 3B and transmission of the measurement data to the information processing apparatus 1 are performed by each transmission module in order to realize continuous information collection. It is repeatedly executed at predetermined intervals (for example, at regular intervals) after the power is turned on. 1 includes a sensor function for measuring a measurement target, a function for recording and processing the measured information, and a wireless connection to the outside of the transmission module. A transmission module that is configured with a function, a power supply function, and the like and is not mounted with a sensor is configured as a small device that is mounted with a wireless function, a power supply function, and the like to the outside of the transmission module.

Examples of sensors mounted on the transmission modules 2 and 3 include physical sensors such as a temperature sensor, a humidity sensor, an acceleration sensor, an illuminance sensor, a flow sensor, a pressure sensor, a ground temperature sensor, and a particle sensor, and CO _2. There are chemical sensors such as sensors, pH sensors, EC sensors, and soil moisture sensors. In the present embodiment, in order to simplify the explanation, it is assumed that each transmission module 2 is equipped with a temperature sensor for measuring the external temperature at the position where each transmission module 2 is arranged, and the transmission modules 2A to 2C. The temperature data measured by 3A and 3B is used for predetermined information processing in the server 1b.

Here, in the system 10, in each transmission path, new transmission information is formed by including the temperature data measured by the self-transmission module in the transmission information transmitted from the upstream transmission module. Send transmission information to the downstream transmission module. As a result, the capacity of the transmission information increases each time the transmission information passes through the transmission module. When the capacity of the transmission information increases, for example, when the transmission environment around the transmission module is not in a suitable state (for example, receiving radio wave interference from another wireless device outside the transmission path), the entire data is transmitted. There is a tendency that the probability that transmission is performed satisfactorily (hereinafter referred to as “success rate”) will be low due to the reason that the time required for the transmission becomes longer. If the transmission between the transmission modules fails, the network configured to transmit the data again is unlikely to succeed in the measurement data transmission unless the transmission environment is improved. It takes a long time to complete data transmission. In other words, smooth transmission of information can be realized if the capacity of transmission information can be reduced as long as it is acceptable from the viewpoint of information collection.

  In addition, if the downstream transmission module receives transmission information with a relatively large capacity, the amount of processing there increases, so the processing load on the downstream transmission module increases and the power required for the processing increases. Such problems are likely to occur. Therefore, even in such a case, suppressing the increase in the capacity of transmission information is considered to contribute to improving the performance of the transmission module.

  Therefore, in the system 10 according to the present invention, the transmission module that includes the measured temperature data in the transmission information should express the temperature data in the form of summarized temperature data summarized so that the capacity is reduced. After determining whether it is in the “predetermined state” or not, the summary temperature data is included in the transmission information instead of the temperature data. As a result, the capacity of transmission information can be reduced within a range that does not hinder predetermined information processing in the information processing apparatus 1, and smooth information transmission and performance improvement of the transmission module can be achieved.

  Based on the above, specific processing by the transmission modules 2 and 3 and the information processing apparatus 1 in the system 10 will be described. The transmission modules 2 and 3 have an arithmetic device, a memory, and the like inside, and various functions are exhibited when a predetermined control program is executed by the arithmetic device. Therefore, FIG. 2 shows functional blocks in which some of the various functions exhibited by the transmission module 2 belonging to the system 10 are imaged. Note that FIG. 2 specifically shows functional blocks for the transmission module 2B on which the sensor is mounted. However, the transmission modules 2A, 2C, 3A, and 3B on which other sensors are mounted are also described as the transmission module 2B. It has the same function. In addition, the transmission module 2C that is not equipped with a sensor is configured to have a functional unit that relays transmission information.

  Here, the transmission module 2B includes a control unit 20, a communication unit 21, a power conversion device 22, a battery 23, a measurement unit 25, and a measurement data recording unit 26 as functional units. Below, each function part which transmission module 2B has is explained. The control unit 20 is a functional unit that performs various controls in the transmission module 2B, and particularly includes a determination unit 201, a forming unit 202, a transmission result processing unit 203, and a transmission prediction unit 204. The determination unit 201 is a functional unit that determines whether or not the transmission module 2B is placed in the predetermined state. In addition, the forming unit 202 uses the temperature data measured by the transmission module 2B as summary temperature data or as it is, the transmission information received from the upstream transmission module 2A (hereinafter referred to as “upstream information”). It is a functional part that forms new transmission information. The transmission result processing unit 203 is a functional unit that performs processing related to the transmission result of transmission information from the transmission module 2B to the downstream transmission module. Examples of the process related to the transmission result include a process for determining whether or not the transmission to the downstream transmission module has been successful, a process for determining the factor when the transmission has failed, and the like. The transmission prediction unit 204 is a functional unit that predicts transmission information transmission failure from the transmission module 2B to the downstream transmission module using the processing result of the transmission result processing unit 203 and the like.

Next, the communication unit 21 is a functional unit that performs communication with the outside of the transmission module 2B, that is, transmission / reception of information. Specifically, the communication unit 21 is formed so as to interact with the control unit 20, and performs transmission / reception between the transmission module 2B via the wireless network and the transmission module 2A corresponding to the upstream transmission module, and the transmission module. It manages transmission and reception between 2B and the transmission module 2C corresponding to the downstream transmission module.

  The power conversion device 22 is a device that converts energy other than the electrical energy given to the self-transmission module into electrical energy in order to generate the drive power of the transmission module 2B. Is stored. Specifically, a vibration power generation apparatus that converts vibration energy applied to the transmission module 2B into electric energy using an electret, a solar power generation apparatus that generates power from sunlight, and the like are adopted as the power conversion apparatus 22. Is possible. In addition, this power converter device 22 cannot always generate electric power, that is, it cannot generate electric power in a state where vibration is not applied to the transmission module 2B or in a state where sunlight is not irradiated. Therefore, the transmission module 2B must perform transmission processing of transmission information under limited supply power. The same applies to the other transmission modules 2A, 2C, 3A to 3C.

  Next, the measurement unit 25 is a functional unit that measures the temperature in the environment where the transmission module 2 </ b> B is disposed via the temperature sensor 24. And the temperature measurement by this measurement part 25 is performed under the instruction | indication of the control part 20, and the measured temperature information is stored by the measurement data recording part 26 at any time. The measurement data recording unit 26 is formed so as to interact with the control unit 20, and in accordance with an instruction from the control unit 20, the recorded measurement data (temperature data) is transferred to the control unit 20 and transmitted by the formation unit 202. The information is formed.

  Next, functional units formed in the server 1b will be described with reference to FIG. The server 1b includes a communication unit 11, a measurement data recording unit 12, and an information processing unit 13. The communication unit 11 is a functional unit that performs communication for collecting transmission information from a transmission module that is located closest to the information processing device 1 in the transmission path via the transmission / reception device 1a. Specifically, the communication unit 11 manages transmission / reception between the transmission modules 2 c and 3 c and the information processing apparatus 1. The measurement data recording unit 12 is a functional unit that records temperature data, which is measurement data, of information included in transmission information transmitted from the transmission modules 2 c and 3 c via the communication unit 11. The temperature data recorded here is transferred to the information processing unit 13, and the information processing unit 13 performs predetermined information processing using the collected temperature data (for example, air conditioning of the space where the transmission module is installed). Processing). Therefore, the sensor mounted on the transmission module may be a sensor for measuring information necessary for predetermined information processing to be performed by the information processing unit 13.

  Next, information transmission processing in the transmission module in the system 10 will be described with reference to FIG. The information transmission processing is performed by the transmission modules 2 and 3 belonging to each of the two transmission paths shown in FIG. 1, but in the following description, in order to explain the processing of the present invention in detail, FIG. An explanation will be given for information transmission processing in the transmission module 2B on the assumption that the transmission information reaches the transmission module 2B via the seven transmission modules including the indicated transmission module 2A. And The information transmission process shown in FIG. 4 is executed in the transmission module 2B, and the process is not performed in the seven transmission modules located on the upstream side. Note that the transmission module immediately upstream of the transmission module 2B is the transmission module 2A shown in FIG.

FIG. 5A schematically shows the data structure of the entire transmission information transmitted by the system 10, and the transmission information is roughly divided into eight data areas. In the present embodiment, five data areas a1 to a5 that are particularly important among the eight data areas will be described. Area a1 (Start Symbol) is a specific byte string indicating the start of transmission information. An area a2 (Destination Address) represents an address of a destination (information processing apparatus 1 in this embodiment) to which transmission information is finally transmitted. A region a3 (Source Address) represents a transmission source address of the transmission information. Area a4 (Data) is an area for storing temperature data detected by a temperature sensor mounted on each transmission module, and area a5 (Terminator Symbol for Data) is a specific byte string indicating the end of transmission information. . FIG. 5B shows a transition of temperature data measured by each transmission module included in the transmission information. As described above, the measurement data in the transmission module 2B is the temperature data T8 (data included in the transmission information at time t80), and the temperature data T1 to T7 are measured by the seven transmission modules on the upstream side, and each temperature is measured. The data is included in the transmission information at times t10 to t70, respectively. Each temperature data is measured by each transmission module at a time before the above time. 5C and 5D show different modes of temperature data stored in the region a4. Details of the storage mode of these temperature data will be described later.

<Information transmission processing>
Now, returning to FIG. 4, the information transmission process will be described. First, in S101, it is determined whether or not the self-transmission module 2B has received transmission information from the transmission module 2A located upstream thereof. This determination is executed when the control unit 20 accesses the communication unit 21. If a positive determination is made in S101, the process proceeds to S102, and if a negative determination is made, the process of S101 is performed again.

  Next, in S102, the temperature data (temperature data T1 to T7 in the present embodiment) included in the received transmission information is held in the memory of the transmission module 2B. After that, in S103, the determination unit 201 uses the temperature data T1 to T7 related to the upstream transmission module held in the memory in S102 and the temperature data T8 related to the transmission module 2B in which this processing is performed. In the meantime, it is determined whether or not a predetermined identical relationship is established. The predetermined identical relationship is defined as a relationship that approximates each of the temperature data T1 to T7 related to the transmission module and the temperature data T8 related to the transmission module 2B to the same or the same level. That is, when the same relationship is established, there are a plurality of approximate temperature data in the transmission information. If a positive determination is made in S103, the process proceeds to S104, and if a negative determination is made, the process proceeds to S107.

  Next, in S104, in response to the determination that the predetermined identical relationship is established in S103, the forming unit 202 forms summary information regarding the temperature data. The formation of the summary information will be described with reference to FIGS. 5 (c) and 5 (d). FIG. 5C shows data formed by adding all the temperature data groups when the summary information is not formed, that is, the temperature data T1 to T8. As shown in FIG. 5B, T1 to T4 have the same value, and T8 included in the transmission module 2B has the same value as T6 and T7. The temperature data group shown in FIG. 5C is data having a capacity of 16 bytes.

FIG. 5D shows a temperature data group when summary information is formed. The summary information is formed according to the following procedure.
(1) Temperature data having a predetermined identical relationship with the temperature data T8 of the transmission module 2B is extracted. In the case of the present embodiment, the temperature data T6 and T7 have the same value as T8, and therefore the temperature data T6 to T8 have a relationship satisfying a predetermined identical relationship.
(2) An average value of temperature data satisfying a predetermined identical relationship is calculated. In the case of the present embodiment, the average value of the temperature data T6 to T8 is represented by “90:00”.
(3) If temperature data other than the temperature data T8 of the transmission module 2B has a predetermined identical relationship among the temperature data, an average value thereof is calculated. In the case of the present embodiment, the temperature data T1 to T4 have the same value, so the average value is calculated as “10:00”.
(4) Final summary information is formed based on the results of (2) and (3). In the present embodiment, as shown in FIG. 5D, the temperature data T1 to T4 are summarized as “FF: 04: 10: 00”. “FF” in the area represented by b1 indicates the beginning of the information averaged by the above (2) or (3). Also, “04” in the area represented by b2 represents the number of temperature data used for averaging, and in this case, corresponds to four temperature data. Also, “10:00” in the area represented by b3 is the above average value. Similarly, the temperature data T6 to T8 are summarized as “FF: 03: 90: 00”. Since the temperature data T5 is not averaged, the value is included in the summary information as it is. Thus, since the summary information includes the average value, the data capacity is 10 bytes, which is smaller than the capacity of the temperature data group shown in FIG. When the process of S104 ends, the process proceeds to S105.

  In S105, the summary information formed in S104 is included in the area a4 shown in FIG. 5 to form new transmission information, and then transmitted to the downstream transmission module 2C via the communication unit 21 in S106. .

  If a negative determination is made in S103, the process proceeds to S107. In S107, new transmission information including the temperature data T8 in the transmission module 2B is formed as it is. Specifically, as shown in FIG. 5C, the temperature data group in which the temperature data T1 to T8 are sequentially connected is included in the area a4 shown in FIG. 5, and new transmission information is formed. Then, the data is transmitted to the downstream transmission module 2C via the communication unit 21.

  As described above, according to the present processing, transmission information using summary information is formed in the transmission module 2B. Therefore, in information transmission via the transmission module thereafter, smooth transmission can be achieved by reducing the capacity of the transmission information. Information transmission can be promoted. Furthermore, since the capacity of transmission information is reduced, the information transmission load in the downstream transmission module 2C is reduced. Therefore, for the transmission module 2C that is driven under a limited power supply, the drive time can be extended, and the drive performance can be improved.

  In the information transmission process described above, since the temperature data T6 to T8 have the same value, it is determined that a predetermined identical relationship is established between the temperature data T8 and the temperature data T6 and T7. The temperature data included in the predetermined fluctuation range with respect to the data T8 may be similarly determined to have the same predetermined relationship. That is, even if the averaging process for the summary information is performed on the temperature data included in the predetermined fluctuation range that is set as a range that can be almost identified with the temperature data T8, the information processing apparatus 1 side Is considered to be valid data. For example, when the difference between the temperature data T8 and the temperature data T6 and T7 falls within a range of ± 5% of the temperature data T8, the above average processing may be performed to combine these three temperature data into one. .

<Modification>
In the above-described embodiment, the average value is adopted as the summary information expression form when the same relationship is established regarding the formation of summary information. Instead of this form, set symbol information that means that the temperature data in a certain transmission module has a predetermined identical relationship with the temperature data in the immediately upstream transmission module, and use the symbol information to summarize information. It may be formed. For example, regarding the temperature data T6, T7, and T8 in the temperature data group shown in FIG. 5C, when expressed as “90: 00: FE: FE”, it means that the temperature data T6, T7, and T8 have the same value. The information processing apparatus 1 interprets and performs predetermined information processing. Thereby, regarding the temperature data T7 and T8, since the capacity of 2 bytes is reduced to 1 byte, the capacity of transmission information in the transmission module 2B is reduced.

In addition, as another form of expressing summary information, when the temperature data in a certain transmission module has a predetermined identical relationship with the temperature data in the immediately upstream transmission module, the temperature data in that transmission module is included. It may not be possible. That is, in the transmission module, the transmission information received from the upstream transmission module is directly transmitted to the downstream transmission module as its own new transmission information. In this case, in the information processing apparatus 1, a transmission module through which transmission information is transmitted is known, and the transmission information finally transmitted includes only temperature data smaller than the number of known transmission modules. If there is not, it is determined that the temperature data having a predetermined identical relationship is omitted, and the information processing apparatus 1 performs predetermined information processing after restoring the omitted temperature data. . In addition, it is preferable that the transmission information includes data indicating temperature data serving as a reference for restoration so that the information processing apparatus 1 can grasp which temperature data is omitted.

  Another embodiment of the information transmission process executed by the transmission module according to the present invention will be described. The information transmission process shown in FIG. 6 is a process executed by the transmission module 2B in the same manner as in the above embodiment, and the same process as the information transmission process shown in FIG. Detailed description thereof is omitted. In the present embodiment, when the process of S102 ends, the process proceeds to S201. In S201, as in S107, new transmission information including the temperature data T8 in the transmission module 2B is formed as it is. Specifically, as shown in FIG. 5C, the temperature data group in which the temperature data T1 to T8 are sequentially connected is included in the area a4 shown in FIG. 5 to form new transmission information, and then in S202. Then, the data is transmitted to the downstream transmission module 2C via the communication unit 21.

  In step S203, the transmission result processing unit 203 determines whether transmission information needs to be sent again, that is, whether retry is necessary because transmission of transmission information in step S202 has failed. . Specifically, the necessity of retry is determined based on the presence / absence of an acknowledge signal transmitted on the side of transmitting transmission information and receiving it. If an affirmative determination is made in S203, the process proceeds to S104. Thereafter, the processes of S104 to S106 are performed, and then the determination of S203 is performed again. If a negative determination is made in S203, the information transmission process is terminated.

  In this information transmission process, when transmission information transmission failure occurs and it is necessary to retry, the forming unit 202 forms new transmission information including summary information. Therefore, the determination process of S203 corresponds to the determination process by the determination unit 201, that is, a process of determining whether or not the transmission module 2B is placed in the predetermined state. According to this information transmission processing that performs such processing, when transmission failure occurs, new transmission information including summary information with a small data capacity is formed and retransmitted for retransmission. Thus, it is possible to eliminate the transmission information transmission failure and to maintain the collection of data necessary for information processing in the information processing apparatus 1.

<Modification 1>
In the information transmission process shown in the above embodiment, summary information is formed by the formation unit 202 when transmission information is retried based on transmission information transmission failure. Instead of such a form, it is predicted in advance whether transmission of transmission information will fail, and if it is predicted that transmission will fail, the summary information by the forming unit 202 is not waiting for the actual transmission failure result. Formation may take place. By forming the summary information by the forming unit 202 after predicting the transmission failure in this way, the information transmission failure can be avoided and smooth information transmission can be maintained. The transmission failure is predicted based on the processing result of the transmission result processing unit 203 by the transmission prediction unit 204. Specifically, when the transmission failure rate in the transmission of the transmission information to the downstream transmission module 2C in the predetermined number of times performed in the past is larger than the reference threshold value, the transmission fails again. Since the possibility is high, it can be predicted that a transmission failure will occur. On the other hand, when the number of times transmission information is received from the upstream transmission module 2A is lower than the reference number (for example, the expected number of receptions) in the predetermined period, it is difficult to receive the transmission information. Therefore, it is also difficult to transmit the transmission information in the same manner, so that it can be predicted that a transmission failure will occur. Also, transmission information transmission failure may be predicted based on RSSI regarding the transmission module 2B and information regarding the presence of noise sources and obstacles existing around the transmission module 2B.

<Modification 2>
In the information transmission process shown in the above embodiment, retry determination is performed based on the presence or absence of an acknowledge signal. However, there is a transmission form in which transmission information is transmitted without using an acknowledge signal. In this case, since it is difficult to determine whether or not the transmission to the downstream transmission module is successful, the transmission information is continuously transmitted a plurality of times in order to increase the transmission success rate as much as possible. Continuous transmission is performed. The present invention can also be applied to a transmission module that performs such continuous transmission. For example, in the case of performing a predetermined number of continuous transmissions, the present invention is not applied to the first transmission or a plurality of transmissions, and the present invention is applied to subsequent transmissions. By performing transmission and application transmission continuously, the amount of information on the network is not excessively increased, and information transmission failures can be avoided.

<Modification 3>
In the information transmission processing shown in the above embodiment, the formation of the summary information is performed by the forming unit 202 using a transmission information transmission failure as a trigger. Instead, the information is formed based on the temperature data capacity in the transmission module 2B. The summary information may be formed by the unit 202. That is, when the capacity of the temperature data in the transmission module 2B exceeds a predetermined threshold amount, or the total data capacity of the temperature data in the transmission module 2B and the transmission information from the upstream transmission module is a predetermined threshold amount. Is exceeded, it is determined that the transmission module 2B is in a predetermined state to reduce the capacity of these pieces of information. Thereby, subsequent information transmission can be performed smoothly.

<Modification 4>
The formation of summary information by the forming unit 202 may be performed based on the state of power supplied to the downstream transmission module 2C and its processing capability. For example, when the transmission module 2B knows that the power in the battery of the transmission module 2C is low, formation of summary information is performed in the transmission module 2B in order to suppress power consumption in the transmission module 2C. And transmit it to the transmission module 2C. Further, in order to reduce the processing amount in the transmission module 2C even when the processing capability of the transmission module 2C (that is, the computing capability of the control unit 20) is not sufficient for transmitting relatively large capacity information. The transmission module 2B forms summary information and transmits it to the transmission module 2C.

  Another embodiment of summary information in the information transmission processing executed by the transmission module according to the present invention will be described. In this embodiment, each transmission module that transmits transmission information includes reception time information that has received transmission information from the upstream transmission module, and transmission time information that transmits transmission information to the downstream transmission module. It is included as information constituting transmission information. At this time, if the reception time information and the transmission time information of each transmission module are included in the transmission information as they are, as shown in FIG. 7A, if the capacity of each time information is 8 bytes, the time information is 40 in total. This is the capacity of bytes. FIG. 7 is a diagram illustrating a total capacity of time information when information transmission is performed using three transmission modules 2A to 2C. In this case, since the transmission module 2A is the most upstream transmission module, the reception time information is not included in the transmission information.

Thus, when the time information in each transmission module is included in the transmission information, the capacity of the transmission information increases, and smooth information transmission may be hindered. Therefore, as shown in FIG. 7B, when transmission information is received from the upstream transmission module, the reception time information and the transmission time information from the upstream transmission module included in the transmission information The difference may be summary information regarding time information. Specifically, in the transmission module 2B, the difference between its own reception time Tr2 and the transmission time Ts1 of the upstream transmission module 2A is set as the transmission time between the transmission modules 2A and 2B, and the transmission module 2C receives its own reception. The difference between the time Tr3 and the transmission time Ts2 of the upstream transmission module 2B is defined as the transmission time between the transmission modules 2B and 2C. Even if the capacity of each time information is set high due to accuracy requirements in predetermined information processing in the information processing apparatus 1 (for example, set as 8-byte information as described above), the time information difference is thus In general, the inter-module transmission time is a very short time. Therefore, even if the capacity is set small (for example, as 1-byte information as shown in FIG. 7), the predetermined time in the information processing apparatus 1 Has little effect on information processing. Then, the information processing apparatus 1 receives the information regarding the difference (Tr2-Ts1) in the transmission module 2B, the difference (Tr3-Ts2) in the transmission module 2C, and the transmission time information of each transmission module, thereby transmitting each transmission. The module reception time information can also be accurately grasped. As a result, the data capacity related to the time information in the transmission information is 26 bytes in total, so that the capacity of the transmission information can be reduced compared to the form shown in FIG.

  Further, as another method related to time information, as shown in FIG. 7C, the reception time information when transmission information is received from the upstream transmission module and the transmission information from itself are transmitted to the downstream transmission module. The difference from the transmission time information may be summary information regarding the time information. Specifically, in the transmission module 2B, the difference between the own transmission time Ts2 and the reception time Tr2 is set as the processing time in the transmission module 2B, and in the transmission module 2C, the difference between the own transmission time Ts3 and the reception time Tr3. Is the processing time in the transmission module 2C. As described above, the processing time in the module, which is the difference between time information, is generally very short, so even if the capacity is set small (for example, as 1-byte information as shown in FIG. 7) Also, there is little influence on the predetermined information processing in the information processing apparatus 1. Then, the information processing apparatus 1 receives the information regarding the difference (Ts2-Tr2) in the transmission module 2B, the difference (Ts3-Tr3) in the transmission module 2C, and the transmission time information of each transmission module, thereby transmitting each transmission. The module reception time information can also be accurately grasped. As a result, the data capacity related to the time information in the transmission information is 26 bytes in total, so that the capacity of the transmission information can be reduced compared to the form shown in FIG.

  In this way, by performing the summarization process by the forming unit 202 on at least time information in the transmission information, the capacity of the transmission information is reduced, and the information processing apparatus 1 is necessary without excessively increasing the amount of information flowing through the network. Information can be suitably transmitted, and smooth information transmission can be realized.
