The function of the control system is to make the DC36V centralized control system able to control the AC220V sign lighting fixtures, such as controlling the lighting or shutting down of the lighting fixtures. However, in the control system of the prior art, there are still some technical problems that need to be solved and processed, as follows: (1) There is no corresponding lighting fault judgment and communication fault judgment for each AC220V sign lighting fixture. (2) When each sign lighting fixture fails, there is no corresponding fault display function or notification function.

[0006] The light source detection module includes a first photoelectric coupler; the main power detection module includes a second photoelectric coupler; the wall switch detection module includes a third photoelectric coupler; the control circuit of the chip is also provided with a relay for realizing high and low voltage level isolation.

[0007] Furthermore, the indicator light function module includes an indicator light power supply connected to each emergency lighting lamp, and a green indicator light connected to the indicator light source and displaying whether a lighting fault and a communication fault occur in the corresponding emergency lighting lamp.

[0008] Furthermore, the light source detection module is also provided with a first transistor connected to the first photoelectric coupler.

[0009] Furthermore, the relay is also connected to the second transistor.

DETAILED DESCRIPTION

[0018] Example 1

[0019] like Figure 1 As shown, the intelligent electric control structure for centrally controlling the emergency evacuation lighting system described in this embodiment 1 is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a control circuit 1 placed on a circuit board of the emergency evacuation lighting system and connected to a chip of the circuit board, a light source detection module 2, a main power detection module 3, a wall switch detection module 14, and an indicator light function module 4 that are respectively connected; the control circuit of the chip contains a 50Hz oscillator 5.

[0020] In this embodiment 1, the light source detection module includes a first photoelectric coupler 6; the main power detection module includes a second photoelectric coupler 7; the wall switch detection module includes a third photoelectric coupler 8; Figure 6 As shown, the control circuit of the chip is also provided with a relay 9 for realizing isolation of high and low voltage levels. The isolation of high and low voltage levels is realized by using relay control in the control circuit.

[0021] The light source detection module is in a high-impedance state and pulled up during initialization. The light source detection module does not detect the port of the control system under normal circumstances. When the sign lighting fixture performs forced emergency lighting or when the wall switch of the wall switch detection module is detected to be started, the port detection of the light source fault detection module will be turned on; when the 50Hz oscillator oscillates at 50Hz and is continuously at a low level, it can be determined that the sign lighting fixtures are normal; when it is continuously at a high level, it can be determined that the light source is faulty.

[0022] The main power detection module is in a high impedance state during initialization. When the 50Hz oscillator oscillates at 50Hz and is continuously at a low level, it can be judged that there is main power; when it is continuously at a high level, it can be judged that there is no main power. This realizes the communication judgment of whether each sign lighting fixture is connected to power.

[0023] The wall switch detection module is in a high-impedance state when initialized. When the 50Hz oscillator oscillates at 50Hz and is continuously at a low level, the detection switch of the wall switch detection module will be turned on, and a signal will be sent to the port of the light source detection module to start the light source fault detection of each sign lighting fixture; when it is continuously at a high level, the detection switch of the wall switch detection module will be turned off. The effect of automatically turning on and off the lighting of each sign lighting fixture is achieved, achieving the purpose of intelligent point control of each sign lighting fixture.

[0024] In this embodiment 1, the indicator light function module includes an indicator light power supply 10 connected to each emergency lighting lamp, and a green indicator light 11 connected to the indicator light source and displaying whether the corresponding emergency lighting lamp has a lighting fault or a communication fault.

[0025] The indicator light function module uses a green indicator light to indicate whether the corresponding sign lighting fixture is normal or faulty. It has indicators such as normal or faulty lighting of the fixture, normal or faulty communication of the fixture when connected to the main power supply, etc., realizing the corresponding sign lighting fixture indication and display function; the green indicator light function of the indicator light function module is as follows:

[0026] 1. The lamp is normal and the communication is normal: light up for 100ms and off for 5s;

[0027] 2. The lamp is normal but the communication fails: it lights up for 2s and goes out for 5s;

[0028] 3. Lamp failure and normal communication: on for 100ms, off for 100ms;

[0029] 4. Lamp failure and communication failure: light on for 2s, off for 100s.

[0030] In the present embodiment 1, the light source detection module is further provided with a first transistor 12 connected to the first photoelectric coupler.

[0031] In the present embodiment 1, the relay is also connected to the second transistor 13 .

[0032] The intelligent electric control structure for centralized control of emergency evacuation lighting system of this embodiment 1 realizes the judgment of high and low voltage levels by setting a 50Hz oscillator in the control electrical appliance, and connects and sets a light source detection module to judge whether a light source fault occurs; when a light source fault occurs, the switch of the corresponding sign lighting fixture is turned off by the wall switch detection module, and at the same time, the indicator light on the indicator light function module is used to indicate whether the corresponding sign lighting fixture is normal or faulty or what kind of fault occurs; finally, the high and low voltage isolation in the control circuit is realized by setting a relay. Therefore, the intelligent electric control structure for centralized control of emergency evacuation lighting system can realize the lighting fault detection and communication fault detection of each sign lighting fixture managed by the control system, and display the corresponding signal through the indicator light on the indicator light function module, and turn off the corresponding switch of the sign lighting fixture with fault, etc., realizing the effect of automatic intelligent control such as intelligent control of the lighting of each sign lighting fixture, fault detection, fault display notification, and automatic shutdown of the corresponding faulty sign lighting fixture.

[0033] The above is only a preferred embodiment of the utility model, and does not limit the structure of the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model still falls within the scope of the technical solution of the utility model.
