It can also monitor the on / off status of the power circuit where the electrical facility is located, facilitating temporary power outages, power restoration, monitoring, and management at the construction site, and saving construction costs.

[0035] For example, in combination Figure 2As shown, the first switch module 10 may include an AC contactor J1.

[0036] Each normally open contact of AC contactor J1 is connected between each phase line of the temporary distribution box at the construction site and the main switch K1, and the control terminals of AC contactor J1 are connected to the first output terminal of controller 50.

[0037] For example, a power conversion module, such as a 220V to 12V power conversion module, can be used to convert the AC power from the temporary distribution box at the construction site into 12V power. The converted 12V power can then be used to power the AC contactor J1, and the on / off state of the power supply circuit for powering the AC contactor J1 can be controlled through the first output terminal of the controller 50.

[0038] For example, in combination Figure 2 As shown, each second switch module 20 may include a relay J2.

[0039] Each normally open contact of relay J2 is connected between the phase line of the power circuit of the corresponding electrical facility at the construction site after the main switch K1 and the neutral line of the temporary distribution box at the construction site. The control terminal of relay J2 is connected to a second output terminal of controller 50.

[0040] For example, in combination Figure 2 As shown, the first monitoring module 30 may include a relay J3.

[0041] The normally open contact of relay J3 is connected between a phase line and a neutral line of the temporary power distribution box at the construction site after the main switch K1, and the control terminal of relay J3 is connected to the first input terminal IN1 of controller 50.

[0044] For example, in combination Figure 2 As shown, the intelligent control and monitoring system for temporary power supply at the construction site also includes: a door magnetic switch (not shown in the figure).

[0045] The magnetic door switch is installed on the door of the temporary power distribution box at the construction site, and the signal output terminal of the magnetic door switch is connected to the access control terminal (IN3) of the controller 50.

[0046] For example, in combination Figure 3 As shown, the intelligent control and monitoring system for temporary power supply at the construction site also includes an operating platform.

[0047] The operating platform and controller 50 can be connected wirelessly.

[0048] The following specific examples illustrate the working process of the intelligent control system for temporary power supply at construction sites provided in this embodiment of the present invention:

[0049] 1. Remote control of main power supply

[0050] When the construction site passes safety inspection and testing and meets the conditions for temporary power supply, the operating platform clicks... Figure 3 Press the main power button to issue a command. Figure 2 When the controller outputs a signal, AC contactor J1 closes, the main power supply is activated, and circuits L3 and C3 are energized. 220V relay J2 feeds back to the controller through circuits IS2 and IC2. The controller then feeds back to the operating platform via a wireless signal. The main power indicator light on the operating platform illuminates, indicating that the main power is on.

[0051] Conversely, when a power outage is required at the construction site, the operating platform clicks... Figure 3 Press the main power off button to issue a command. Figure 2 When the controller output 1 sends a signal, the AC contactor J1 is disconnected, the main power supply is cut off, the L3 and C3 circuits are de-energized, the 220V relay J2 wiring IS2 and IC2 circuits have no signal, the controller feeds back to the operating platform via wireless signal, the main power on / off indicator light on the operating platform turns off, indicating that the main power supply is in the off state.

[0052] 2. Electrical circuit control

[0053] For example, temporary lighting requires power; the operating platform clicks... Figure 3 The light switch in the stairwell was activated, issuing a command. Figure 2 When the controller output 2 sends a signal, relay J3 closes, energizing circuits L1 and C1 to supply power to the stairwell temporary lighting, and circuits L2 and C2 are energized. 220V relay J4 feeds back to the controller through circuits IS1 and IC1, and the controller then feeds back to the operating platform via a wireless signal. The stairwell lighting on / off indicator light on the operating platform illuminates, indicating that the stairwell lighting is on.

[0054] Conversely, temporary lighting requires a power outage, and the operating platform needs to be clicked. Figure 3 The light switch in the stairwell issues a command. Figure 2When the controller output 2 sends a signal, relay J3 disconnects, the L1 and C1 circuits are de-energized, the temporary stairwell lighting is de-energized, the L2 and C2 circuits are de-energized, the 220V relay J4 has no signal through the IS1 and IC1 circuits, the controller feeds back to the operating platform via wireless signal, and the stairwell lighting on / off indicator on the operating platform turns off, indicating that the stairwell lighting is in the off state.

[0055] 3. Monitoring the opening and closing status of temporary power distribution boxes at the construction site.

[0056] A magnetic door switch is installed on the door of the temporary power distribution box at the construction site. Its output is connected to the access control terminal IN3 of the network controller. When the temporary power distribution box door is closed, the power distribution box door closed indicator light on the operating platform is on. When the temporary power distribution box door is open, the power distribution box door closed indicator light on the operating platform is off, and the opening and closing status of the temporary power distribution box door is monitored in real time.

[0057] It should be noted that, as Figure 2 As shown, the second switch module 20 and the second monitoring module 40 in the construction site temporary power intelligent control and monitoring system may include one, two or more sets to monitor and remotely control the on / off status of other power facilities at the construction site.

[0058] This invention enables remote control of the power circuit (i.e., the circuit containing the temporary lighting switch) by installing contactors or relays in the temporary distribution box at the construction site that require control and monitoring, and using a controller to control the on / off state of the contactors or relays. The relays can be time relays to perform timed on / off control of the power circuit and feed back the on / off status to the operating platform, facilitating remote monitoring of the power circuit's on / off status.

[0059] The controller can utilize wireless communication technology, and the operating platform can be a mobile phone, tablet, or other terminal device. An app can be installed on these devices, allowing operators to remotely control the power circuits from the control room. This saves manpower and time compared to manual operation, while also enabling real-time monitoring of all temporary power circuits on-site, thus reducing construction costs and facilitating power management.

[0060] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
