The terminal 30 may also execute a predetermined program to enable remote operation of the full two-wire control unit 23.

<Call function>
FIG. 3 is a diagram for explaining the call function realized by the construction site information system 100. In the example of FIG. 3, the display unit 15 of the distribution board 10B displays a user who is making a video call using the control board 20 of the office 2. Meanwhile, the UI 215 of the control board 20 of the office 2 displays an image captured by the camera unit 16 of the distribution board 10B. In addition, audio data is also transmitted and received bidirectionally and played back. That is, audio data inputted via the UI 215 of the computer 21 of the control board 20 is transmitted to the distribution board 10 via the second communication IF 214 and the local network, and for example, the processor of the communication unit 13 outputs it from the speaker of the communication unit 14. Meanwhile, audio data inputted via the microphone of the communication unit 14 of the distribution board 10 is transmitted to the control board 20 via the communication unit 13 and the local network, and the computer 21 outputs it from the UI 215.

The intercom units 14 of the multiple distribution boards 10 can make voice calls or video calls between each other, or between the intercom units 14 of the distribution boards 10 and the computer 21 of the control board 20. That is, two-way communication of voice data is performed. Note that video data may be one-way communication rather than two-way communication, and may not be transmitted or received (that is, it may be a call by voice only). Also, three or more devices may make a group call. A group call is realized by each of three or more devices performing two-way communication of voice data with the other devices. In a group call, video data may also be transmitted and received. A call may be initiated by making a call based on a protocol for call control, such as SIP (Session Initiation Protocol).

At a construction site, for example, morning meetings and work group meetings are held for all workers to share information such as work plans and precautions. If the group call function of the construction site information system 100 allows workers to participate in meetings remotely, the time required for workers to travel and waiting time can be reduced, improving overall work efficiency. Also, for example, if a problem occurs at the site, workers can use the communication unit 14 and camera unit 16 of the distribution board 10 to easily share information with users such as workers near other distribution boards 10 and supervisors in the office 2.

<Power supply control>
4 is a diagram for explaining the use of power supply control and sensing data. The construction site information system 100 can remotely control the turning on and off of the lighting device 18 using a full two-wire remote control. Also, the computer 21 of the control panel 20 may receive a request based on a user's operation on the terminal 30 and control a signal sent from the full two-wire control unit 23. The full two-wire control unit 12 on the distribution panel 10 side switches the relay 121 on/off based on the received signal, and controls the lighting device 18 connected to the relay 121. Remote power supply control can suppress forgetting to turn off the lights and reduce the effort required for workers to move to turn off the lights.

<Use of sensing data, etc.>
The distribution board 10 may control the display of the display unit 15 based on the amount of power usage measured by the power supply unit 11 or the power measurement unit 22 of the control board 20, or data measured by the sensor group 17. Furthermore, at least a part of the display content may be determined by, for example, the computer 21 of the control board 20 or a processor included in the distribution board 10 based on sensing data.

4, information on the amount of power used, temperature, and humidity is displayed in area 151 of the display unit 15. In addition, a warning is displayed in area 152 to warn about heat stroke. The amount of power used may be the amount of power used in the distribution board 10, or the amount of power used in the entire construction site. In addition, if the amount of power used exceeds a predetermined threshold, a warning may be output to the display unit 15, the control board 20, or the terminal 30. The temperature is displayed based on information output by the temperature sensor 171. The humidity is displayed based on information output by the humidity sensor 172. In addition, the distribution board 10 or the control board 20 may calculate an index value representing the risk of heat stroke based on the temperature and humidity, and output a warning when a predetermined threshold is exceeded. In addition, the sensor group 17 may acquire the dry bulb temperature, the wet bulb temperature, and the black bulb temperature, and the distribution board 10 or the control board 20 may calculate an index value such as a heat index (WBGT: Wet Bulb Globe Temperature).

In addition, information on noise, wind speed, and oxygen concentration is displayed in area 153 of the display unit 15. Noise is displayed based on at least one of the information output by the noise sensor 173 and the information output by the vibration sensor 174. Wind speed is displayed based on the information output by the wind speed sensor 175. Oxygen concentration is displayed based on the information output by the oxygen concentration sensor 176. A warning is displayed in area 154 to warn about an oxygen deficiency state (hypoxia). In this way, a warning may be output when the sensing data falls below a predetermined threshold. The display in FIG. 4 is one example, and the construction site information system 100 may evaluate other risks and display warnings, etc.

<Display database information>
FIG. 5 is a diagram for explaining the display of information stored in the database. In the example of FIG. 5, the display unit 15 of the distribution board 10 displays a schedule 155 and site information 156. The display unit 15 may display other information stored in the storage device 212 (database). The information stored in the database of the control board 20 is transmitted to the requesting distribution board 10 by the computer 21 of the control board 20 in response to a request from the distribution board 10, for example. The display unit 15 of the distribution board 10 is equipped with, for example, a touch panel, and a worker can request information from the control board 20 by operating the display unit 15. The schedule 155 is information about the planned work process. The site information 156 is information such as restricted access areas, the operation status of heavy machinery, and the delivery route. At a construction site, the number of elevators in operation is limited, and the area that can be passed through changes as the work progresses. According to this embodiment, a worker can check information about the construction site without having to carry around paper documents or a terminal such as a tablet.

<Modification>
FIG. 6 is a diagram showing an example of a construction site information system 100 according to a modified example. In the example of FIG. 6, some of the components of the distribution board 10 are equipped with a wireless communication module, and communicate with the distribution board 10 within a predetermined radio wave reachable range. For the wireless communication, communication standards such as wireless LAN, Bluetooth (registered trademark), and ZigBee can be used. In the example of FIG. 6, the camera unit 16, the sensor group 17, the lighting device 18, and the alarm device 19 communicate wirelessly with the distribution board 10. The power supply to these devices may be a wireless power supply system or a battery-powered (rechargeable) system. The lighting device 18 does not have to be controlled by a full two-wire remote control. For example, the lighting device 18 may be a device that illuminates the distribution board or its surroundings for crime prevention, or may be a device equipped with a human sensor. The alarm device 19 is a device that issues an alarm by sound or by turning on or blinking a warning light based on communication from the distribution board 10. The alarm device 19 may sound to notify warning information, for example, as shown in areas 152 and 154 of the display unit 15 in Fig. 4. The alarm device 19 may also sound when a call is received from another distribution board 10, etc. By connecting these devices wirelessly, their placement can be freely changed at the construction site, improving convenience.
