DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a telemeter device according to an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a telemeter system configured using a telemeter device 1 according to an embodiment of the present invention. The telemeter device 1 includes a CPU 10 that performs overall control of each unit, an EEPROM 11, an EPROM 12, a RAM 13, a communication control unit 15 connected to the data bus 14, a timer 16, a power supply control unit 17, and I / Os 18-1 to 18-3. , And a radio 19 are provided. An interrupt signal is sent from the communication control unit 15, the timer 16, and the I / Os 18-1 to 18-3 to the power supply control unit 17 through the activation bus 20, and from the power supply control unit 17 to the activation bus. An interrupt signal is sent to the CPU 10 via 30.
[0011]
A debris flow sensor 31 composed of a wire or the like is connected to the I / O 18-1, a water level gauge 32 is connected to the I / O 18-2, and a rain gauge 33 is connected to the I / O 18-3.
[0012]
The telemeter device 1 is connected to the telemeter monitoring device 2 via a wireless line. The telemeter monitoring device 2 includes a radio 21, a data collection unit 22 including a CPU, and an instruction input unit 23 including a keyboard and a display CRT. The instruction input unit 23 can give a data collection instruction to the telemeter device 1.
[0013]
The data of the tables shown in FIGS. 2 to 4 is set in the EEPROM 11 of the telemeter device 1 in advance or when necessary. When data is set in the EEPROM 11 when necessary, a data input device is connected to the data bus 14 to input data, or data is input from the instruction input unit 23 of the telemeter monitoring device 2. Receiving this input data, the CPU 10 writes the data to the EEPROM 11.
[0014]
The table of FIG. 2 is a table for specifying an event code (identification information) and priority from the IO port number, the bit position of the port, etc., where the interrupt is generated , and the table of FIG. 3 is based on the event code (identification information). FIG. 4 is a table for determining the connection port and reference information at the time of collection from the data collection target device. The reference information is data necessary for data collection, such as the number of digits of data to be collected, an error check method, and a collection interval time.
[0015]
The EPROM 12 stores a program corresponding to the flowcharts shown in FIGS. 5 and 6, and the CPU functions as a processing unit. When the CPU 10 receives the interrupt signal, the program corresponding to the flowchart of FIG. 5 starts and specifies the interrupt generation position for obtaining the event code (S1). When an interrupt signal arrives at the CPU 10 via the activation bus 20, the power supply control unit 17, and the activation bus 30, the CPU 10 indicates an interrupt generation position (interrupt source), for example, a port number based on the data of the activation bus 30. It is obtained by fetching from the data of the bit position to be set.
[0016]
Next, the event code and the priority order are obtained from the interrupt position obtained above with reference to the table of FIG. 2 (S2). Then, a plurality of interrupts are generated, and it is detected whether or not the processing in which the processing order is determined based on the priority is necessary (S3). Here, if YES is determined, the processing from the higher priority to the lower processing is sequentially performed based on the priority (S4). On the other hand, when branching to NO in step S3, the process corresponding to the event code is executed (S5).
[0017]
Details of the processing in steps S4 and S5 are performed as shown in FIG. That is, the data collection destination (collection target device) is specified from the event code with reference to the table of FIG. 3 (S6). For example, if the event code is “02”, “device 03”, “device 05”,..., “Device 02” are obtained as data collection destinations.
[0018]
Next, the connection port is specified from the data collection destination information obtained above using the table shown in FIG. 4, and reference information is also obtained using the table shown in FIG. Collection is performed (S7). For example, when “device 02” is the data collection destination, the connection port number is “1”, the data is 3 digits, and there is no parity check. Three-digit data will be obtained. Data obtained from all data collection destinations in this way is transmitted to the telemeter monitoring device 2 (S8). In step S4, the process of FIG. 6 is repeated for the number of interrupts. Further, in the case of an interruption due to an instruction from the telemeter monitoring device 2, the data collection target device and reference information may be instructed according to the content of the instruction.
[0019]
In the telemeter device 1 configured as described above, the call activation type and the event activation can be achieved by setting the contents of the tables shown in FIGS. It can also be changed to have one of the functions of the mold. That is, when the port number of the communication control unit 15 is described in the port column of the table of FIG. 2, it can be a call activation type according to an instruction from the telemeter monitoring device 2, and I / O 18-1 to When at least one port number 18-3 is described, the event activation type can be set.
[0020]
As described above , according to the embodiment of the present invention , in the telemeter device connected to the telemeter monitoring device and the plurality of sensors and transmitting collected information collected from the plurality of sensors to the telemeter monitoring device, the telemeter monitoring A storage means for storing a plurality of interrupts generated from the apparatus and each sensor in association with identification information and storing information corresponding to the identification information is stored. When an interrupt occurs, the location of the interrupt source is determined using the storage means. The identification information is specified based on the identification information, the processing content corresponding to the identification information is obtained, and the corresponding information collection processing is performed. Therefore, the interrupt generated from the telemeter monitoring device is also generated from each sensor due to the storage content of the storage means. Data collection processing can also be performed for interrupts.
[0021]
Further, in the telemeter device according to the embodiment of the present invention , the storage unit stores priority data together with processing content information corresponding to the identification information, and when a plurality of interrupts occur, Since the process is executed in the order based on the priority order data in the storage means, when a plurality of interrupts occur, the process is appropriately executed in the order based on the priority order data.
[0022]
In the telemeter device according to the embodiment of the present invention , the storage means includes a first table for specifying the processing content and identification information from the position of the interrupt source, and a second table for specifying a data collection target from the identification information. And a third table that stores connection information and reference information at the time of data collection for each data identification target. Therefore, the processing contents and identification information are specified from the position of the interrupt source, and the identification is performed. It is possible to identify the data collection target from the information, obtain the connection position for each data identification target and reference information at the time of data collection, execute the process, and collect the necessary data according to the desired setting . Further, in the telemeter device according to the embodiment of the present invention, the storage means is configured to be rewritable, and an interrupt generated only from the telemeter monitoring device is made to correspond to the identification information, or a plurality of interrupts generated only from each sensor are identified. Since it is possible to switch between correspondence to information and whether multiple interrupts generated from the telemeter monitoring device and each sensor can correspond to identification information, it has both functions of call activation type and event activation type. Can be appropriately selected, and a telemeter device can be realized as required.
