Description

Technical Field

[0001] This utility model relates to the field of electrical control technology, specifically an intelligent lighting control system for warehouses. Background Technology

[0002] The security and control facilities in the warehouse frequently use switching power supplies, and personnel often forget to turn them off when leaving. Electrical equipment left in standby mode for extended periods not only wastes electricity and reduces its lifespan, but can also lead to fires, electric shocks, and other safety accidents. However, traditional warehouse-style distribution boxes cannot control power outages based on usage conditions, and in situations where there is no personnel on duty, indoor temperature or humidity is too high, or in the event of a fire or flood, there is a significant potential for safety hazards. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an intelligent lighting control system for warehouses. By optimizing the electrical circuit structure and integrating a time relay in the door control trigger circuit, the system can achieve a delayed shutdown function of the lighting after the door is closed. This eliminates the need to change the original door structure or add sensors, thus solving safety hazards with low-cost hardware improvements while maintaining the simplicity and reliability of the system.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an intelligent lighting control system for warehouses, including a limit switch installed on the warehouse door, the limit switch and the coil being located on the same circuit, and an AC contactor being installed on the circuit where the warehouse lighting lamp is located;

[0005] The linkage between the AC contactor and the coil enables the on / off control of the lighting circuit inside the warehouse.

[0006] In a preferred embodiment, the interior lighting is connected to a 220V power supply, which is also equipped with a parallel circuit with a transformer. The transformer converts the 220V AC power output from the 220V power supply into 24V AC power and supplies power to the coil.

[0007] In a preferred embodiment, the limit switch is fixedly installed on the civil structure inside the door frame of the warehouse door.

[0008] In a preferred embodiment, the contact portion of the limit switch extends laterally to the vertical surface where the door frame is located.

[0009] In a preferred embodiment, when the door panel of the warehouse door closes, it collides with the limit switch contact portion in the vertical plane where the door frame is located.

[0010] In a preferred embodiment, the limit switch is in a normally closed state, and the limit switch is disconnected when the door panel collides with the limit switch contact.

[0011] In a preferred embodiment, a time relay is connected in series in the circuit containing the coil. The time relay is configured to cut off the power supply to the coil after a preset time when the limit switch is opened, so as to delay the turning off of the cabin lighting.

[0012] The intelligent lighting control system for warehouses provided by this utility model, by adopting the above-described structure, has the following beneficial effects:

[0013] (1) The warehouse intelligent lighting system can automatically turn the lights on and off according to the personnel entering the warehouse, which greatly reduces the situation where the warehouse keeper forgets to turn off the lights because of the manual turning on and off of the lights, thus saving energy consumption;

[0014] (2) The intelligent lighting system in the warehouse can greatly reduce the possibility of electric shock or fire caused by the warehouse keeper manually turning the lights off or off the power box;

[0015] (3) The warehouse intelligent lighting system can turn on the lights as soon as managers and warehouse keepers enter the warehouse for inspection, thereby improving work efficiency;

[0016] (4) After the introduction of the time relay, the lights will not turn off immediately when the door is closed, but will turn off after a preset time (such as 30 seconds to 1 minute). This solves the safety hazards such as obstructed vision, bumps and falls caused by the sudden loss of light when personnel have not completely evacuated. It is especially suitable for dim lighting or emergency evacuation scenarios. Attached Figure Description

[0021] like Figure 1-2 In the present invention, an intelligent lighting control system for a warehouse includes a limit switch 7 installed on the warehouse door 6, the limit switch 7 and the coil 5 being located on the same circuit, and an AC contactor 3 being installed on the circuit of the warehouse lighting lamp 2 inside the warehouse.

[0022] The AC contactor 3 and coil 5 work together to control the on / off state of the indoor lighting circuit 2.

[0023] In a preferred embodiment, the warehouse lighting lamp 2 is connected to a 220V power supply 1. The 220V power supply 1 is also equipped with a parallel circuit with a transformer 4. The transformer 4 converts the 220V AC power output by the 220V power supply 1 into 24V AC power and supplies power to the coil 5.

[0024] In a preferred embodiment, the limit switch 7 is fixedly installed on the inner side of the door frame 8 of the warehouse door 6 on the civil engineering structure.

[0025] In a preferred embodiment, the contact portion of the limit switch 7 extends laterally to the vertical surface where the door frame 8 is located.

[0026] In a preferred embodiment, when the door panel 9 of the door 6 is closed, it collides with the contact portion of the limit switch 7 in the vertical plane where the door frame 8 is located.

[0027] In the preferred embodiment, the limit switch 7 is in a normally closed state, and the limit switch 7 is disconnected by the door panel 9 colliding with the contact of the limit switch 7.

[0028] In a preferred embodiment, a time relay 10 is connected in series in the circuit containing the coil 5. The time relay 10 is configured to cut off the power supply to the coil 5 after a preset time when the limit switch 7 is opened, so as to delay the turning off of the cabin lighting 2.

[0029] The intelligent lighting control system for warehouses disclosed in this utility model has the following working process:

[0030] Door Opening State: When the door 6 is opened, the limit switch 7 returns to its normally closed state. The 24V power supply forms a circuit through the limit switch 7 → time relay 10 coil → time relay 10 normally closed contact (KT-1) → AC contactor coil 5. The main contact KM-1 of AC contactor 3 closes, and the interior lighting 2 lights up.

[0031] Door closing trigger: After the work inside the warehouse is completed, the warehouse door 6 closes, the door plate 9 presses the contact of the limit switch 7 to make it move, the coil of the time relay 10 is de-energized, and its normally closed contact (KT-1) enters the delayed disconnection stage (if preset to 1 minute).

[0032] Delayed light shut-off: During the delay period, the AC contactor coil 5 remains energized through the normally closed contact (KT-1) of the time relay 10, and the light 2 continues to be lit; after the delay ends, the KT-1 contact opens, the coil 5 is de-energized, the main contact KM-1 of the AC contactor 3 opens, and the light 2 turns off.

[0033] In addition, based on the above structure, the output of the time relay 10 can be further connected in parallel with an audible and visual alarm (not shown in the figure). When the limit switch 7 is disconnected and the trigger delay is completed, the alarm will be activated to remind the personnel in the warehouse of the remaining lighting time, further enhancing the safety warning.
