In order to manage the operation state of these process system component devices, there is a process system component device operation state management system via a wireless network. In the process system component equipment operation state management system, an operation state providing device that acquires an operation state from a process system component device, and an operation state management device that receives and manages the operation state from each operation state provision device are individually provided. It has a timing circuit. For this reason, in order to make the transmission / reception timing coincide between each operation state providing device and the operation state management device, the operation state information is transmitted / received after synchronization between the respective timing circuits. .

  A conventional target information management system will be described using a control system to which the sensor data collection system shown in FIG. 19 is applied. The control system to which the sensor data collection system is applied includes the sensor slave units 1a, 1b, 1c, and 1d, the wireless master unit 2, the control device 3, and the environment control device 4 (for example, the lighting fixture 5 and the air conditioning device 6). It has.

  In this control system, the illuminance is measured by the sensor slave units 1a and 1d arranged in the area to be controlled, and the temperature and humidity are measured by each of the sensor slave units 1b and 1c.

The wireless master device 2 determines an offset time for shifting the transmission timing of the sensor slave device 1 so that data transmitted from the plurality of sensor slave devices 1 do not collide, and transmits the determined offset time to the sensor slave device 1 To do.

  When receiving the measurement data from the sensor slave unit 1, the wireless master unit 2 temporarily stores the received measurement data in a storage area assigned to each sensor slave unit in the storage unit 25. The CPU 30 of the control device 3 transmits a data transmission request from the communication unit 31 to the wireless master device 2 at a predetermined timing in order to be used for control of the environment control device 4. When the data transmission request is received by the wired communication unit 23 of the wireless master device 2, the data transmission request is output from the wired communication unit 23 to the MCU 20, and the MCU 20 transmits the measurement data of the desired sensor slave device 1 from the storage unit 25.

For example, since the control device 3 cannot change the transmission / reception timing of the measurement data in the sensor slave unit 1, it cannot cope with the change in the network configuration due to the increase or decrease of the sensor slave unit 1.

  Further, in the wireless master device 2, there is a collision between transmission / reception of measurement data between the wireless master device 2 and the sensor slave device 1 and transmission / reception of measurement data between the control device 3 and the wireless slave device 2. There is a point that should be improved that efficient transmission / reception cannot be performed unless it is prevented from occurring.

The relay operation state transmission request time information has an operation state transmission request time description area, a communication standby start time description area, and a communication standby end time description area. In the operation state transmission request time description area, an operation state transmission request time which is a time at which the trap operation state management device 120 requests transmission of operation state information is described. Note that, as the operation state transmission request time, the next operation state transmission request time of the operation state transmission request information transmitted to itself or to the communication relay device 130 belonging to the subordinate is used. In the communication standby start time description area, a communication standby start time for starting the communication standby state of the wireless communication circuit 130h is described in order to acquire the operation state transmission request information. In the communication standby start time description area, a communication standby end time for ending the standby state of the wireless communication circuit 130h is described. The communication standby start time and the communication standby end time are calculated by the communication relay device 130 for each operation state transmission request time. Note that the communication standby start time and the communication standby end time are predetermined time before the next operation state transmission request time of the predetermined operation state transmission request information acquired by the communication relay device 130 from the trap operation state management device 120. Set as the time after.

Sixth Operation of Trap Operating State Management System 100 Regarding the operation of the trap operating state management system 100, the flowchart showing the operation of the trap operating state management device 120 shown in FIG. 15, the operation of the communication relay device 130 shown in FIGS. A description will be given below with reference to a flowchart illustrating the operation of the trap operation state providing apparatus 110 illustrated in FIG.

1. Operation of Trap Operating State Management Device 120 As shown in FIG. 15, the CPU 120a of the trap operating state management device 120 acquires the current time from the time measuring circuit 120j, and the acquired current time is the operating state transmission request schedule information (see FIG. 9). It is determined whether or not the time exists in the operation state transmission request time description area (S1501). If the CPU 120a determines that the current time is a time that exists in the operation state transmission request time description area of the operation state transmission request schedule information, the system configuration device ID corresponding to the acquired current time in the operation state transmission request schedule information The system configuration device ID described in the description area is acquired, and for the acquired system configuration device ID, from the next operation state transmission request time description area, the current time is the most current time. The near operation state transmission request time is acquired as the next operation state transmission request time (S1503).

  The CPU 120a generates operation state transmission request information (see FIG. 10) (S1505). Here, the CPU 120a uses the system configuration device ID and the next operation state transmission request time acquired in step S1503 as values of the system configuration device ID description area and the next operation state transmission request time description area of the operation state transmission request information, respectively. Set. The CPU 120a transmits the generated operation state transmission request information to the communication relay device 130 of the system configuration device ID acquired in step S1503 (S1507).

  If the CPU 120a determines that the intermediate collection operation state information (see FIG. 13) has been received from the communication relay device 130 that has transmitted the operation state transmission request information (S1509), the system component device ID is based on the received intermediate collection operation state information. System configuration device ID described in the description area, operating state acquisition time described in the operating state value acquisition time description area, operating state type described in the operating state type description area, and operating state value description area The operation state values described in the above are associated with each other and described in the operation state information DB (see FIG. 11) together with the reception time of the intermediate collection operation state information (S1511). The CPU 120a repeats the processing from step S1501 to step S1513 until the operation is completed (S1515), including when it is determined that the intermediate collection operation state information has not been received for a predetermined time (S1513).

2. Operation of Communication Relay Device 130 As shown in FIG. 16, the time measuring circuit 130j of the communication relay device 130 communicates the relay operation state transmission request time information (see FIG. 14) whose time being measured is stored in the memory 130b. If it is determined that the communication standby start time described in the standby start time description area has come (S1601), the CPU 130a is activated (S1603). The CPU 130a places the wireless communication circuit 130h in a standby state (S1605).

  When the CPU 130a obtains the operation state transmission request information (see FIG. 10) from the trap operation state management device 120 (FIG. 15: Step S1507) (S1607), it is described in the system configuration device ID description area of the obtained operation state transmission request information. It is determined whether or not the system configuration device ID that has been set is its own system configuration device ID (S1609). When the CPU 130a determines that the system configuration device ID described in the system configuration device ID description area is its own system configuration device ID, the next operation state transmission request described in the next operation state transmission request time description area The time is acquired (S1611).

  The CPU 130a acquires broadcast device information (see FIG. 12) (S1613). The CPU 130a acquires the system configuration device ID described in the system configuration device ID description area of the broadcast device information (S1615). The CPU 130a generates broadcast operation state transmission request information (S1617). The broadcast operation state transmission request information generated here is the same as the operation state transmission request information generated by the trap operation state management device 120 (see FIG. 15: step S1505, FIG. 10). However, when generating the broadcast operation state transmission request information, the CPU 130a indicates the system operation device ID acquired in step S1615 and the next operation state transmission request time acquired in step S1611, respectively. Are set to the value of the system component device ID description area and the value of the next operation state transmission request time description area.

  When the CPU 130a generates the broadcast operation state transmission request information for all the system configuration device IDs acquired in step S1615 (S1619), the CPU 130a transmits all the generated broadcast operation state transmission request information to each of the system configuration device IDs. At the same time, it transmits to the trap operating state providing device 110 (S1621).

  On the other hand, if the CPU 130a determines in step S1609 that the system configuration device ID described in the system configuration device ID description area of the acquired operation state request information is not its own system configuration device ID, the communication belonging to the lower level of itself. The next operation state transmission request in the next operation state transmission request time description area is determined from the operation state transmission request information acquired in step S1607 (see FIG. 16). The time is extracted (S1623). The CPU 130a calculates a communication standby start time and a communication standby end time from the acquired next operation state transmission request time, and additionally adds to the relay operation state transmission request time information (see FIG. 14) stored in the memory 130b. This is described (S1625). The calculation of the next communication standby start time and the communication standby end time will be described later.

  And CPU130a transmits the acquired operation state transmission request information to another communication apparatus by a general communication relay process using a routing table (S1627). The CPU 130a enters a so-called sleep state in which the power supply to other than the memory 130b and the timing circuit 130j is stopped (S1629).

  Moving to FIG. 17, when the CPU 130a determines that the operation state information (see FIG. 7) has been received from the trap operation state providing device 110 that has transmitted the broadcast operation state transmission request information (S1631), the CPU 130a displays the received operation state information. In association with the trap operation state providing apparatus 110 that has transmitted the operation state information, the operation state information is temporarily stored in the memory 130b (S1633). When the CPU 130a determines that the operation state information has been received from all the trap operation state providing devices 110 that have transmitted the broadcast operation state transmission request information (S1635), the CPU 130a operates from all the operation state information stored in the memory 130b. The operating state acquisition time described in the state value acquisition time description area, the operating state type described in the operating state type description area, and the operating state value described in the operating state value description area are extracted. The intermediate collection operation state information (see FIG. 13) is generated in association with the system configuration device ID of the trap operation state providing apparatus 110 with which the operation state information is associated (S1637). The CPU 130a transmits the generated intermediate collection operation state information to the trap operation state management device 120 (S1639), and ends the standby state of the wireless communication circuit 130h (S1641).

  If a predetermined time has elapsed before receiving the operation state information from all the trap operation state providing devices 110 that have transmitted the broadcast operation state transmission request information (S1643), the CPU 130a stores the memory 130b at that time. The intermediate collection operation state information is generated based on the operation state information stored in (S1637) and transmitted to the trap operation state management device 120 (S1639).

  The CPU 130a extracts the next operation state transmission request time in the next operation state transmission request time description area from the operation state transmission request information acquired in step S1607 (see FIG. 16) (S1645). The CPU 130a calculates a communication standby start time and a communication standby end time from the acquired next operation state transmission request time, and additionally adds to the relay operation state transmission request time information (see FIG. 14) stored in the memory 130b. This is described (S1647). The CPU 130a uses the communication standby time described in the communication standby time information stored in the memory 130b when calculating the next communication standby start time and the communication standby end time. The CPU 130a calculates the next communication standby start time and the communication standby end time by subtracting and adding the communication standby time to the next operation state transmission request time.

  Then, the CPU 130a enters a so-called sleep state in which the power supply to other than the memory 130b and the timing circuit 130j is stopped (S1649).

3. Operation of Trap Operating State Providing Device 110 As shown in FIG. 18, the timing circuit 110j of the trap operating state providing device 110 has operating time transmission request time information in which the time being measured is stored in the memory 110b (see FIG. 8). When the communication standby start time in the communication standby start time description area is determined (S1801), the CPU 110a is activated (S1803). The CPU 110a places the wireless communication circuit 110h in a standby state (S1805).

  When receiving the broadcast operation state transmission request information from the communication relay device 130 (S1807), the CPU 110a acquires the upper communication relay device information stored in the memory 110b (S1809). Here, the higher-level communication relay device information is information in which the system configuration device ID of the communication relay device 130 that can directly communicate with itself is described.

  The CPU 110a transmits the operating state information via the wireless communication circuit 110h to the communication relay device 130 of the higher-level communication relay device information acquired in step S1809 (S1811). In addition, when transmitting provision operation state information, CPU110a searches for the free channel in radio | wireless communication using CCA (Clear Channel Asset). Thereby, the operating state information can be efficiently provided to the communication relay device 130.

  When the transmission of the operation state information is finished (S1813), the CPU 110a finishes the standby state of the wireless communication circuit 110h (S1815). Similarly, when the CPU 110a determines that a predetermined time has elapsed since the transmission of the first operation state information without completing the transmission of the provision operation state information (S1817), the CPU 110a similarly ends the transmission of the provision operation state information. Then, the standby state of the wireless communication circuit 110h is terminated (S1815).

  The CPU 110a extracts the next operation state transmission request time in the next operation state transmission request time description area from the broadcast operation state transmission request information acquired in step S1807 (S1819). The CPU 110a calculates the communication standby start time and the communication standby end time from the acquired next operation state transmission request time, generates operation state transmission request time information (see FIG. 8), and stores and holds it in the memory 110b (S1821). ). The CPU 110a uses the communication standby time described in the communication standby time information stored in the memory 110b when calculating the next communication standby start time and the communication standby end time. The CPU 110a calculates the next communication standby start time and the communication standby end time by subtracting and adding the communication standby time to the next operation state transmission request time.

Then, the CPU 110a enters a so-called sleep state in which the power supply to other than the memory 110b and the timing circuit 110j is stopped (S1823).
