[0031] The parameter setting screen is connected to the display screen interface and transmits data to the single-chip microcomputer through the display screen interface;

[0032] Specifically, the parameter setting screen is used to set relevant lighting parameters and display the working status of the terminal devices respectively controlled by the two groups of dimming control units in real time; the parameter setting screen reads the working status data sent by the single-chip microcomputer in real time and displays the working status of the terminal devices in real time; if the staff sets the parameters on the parameter setting screen, the parameter setting screen transmits the parameter data to the single-chip microcomputer, and the single-chip microcomputer performs dimming control according to the received data;

[0033] It should be noted that the parameter setting screen is a touch screen.

[0034] The illuminance meter is connected to the illuminance meter interface and transmits data to the single-chip microcomputer through the illuminance meter interface; the illuminance meter is used to detect the light intensity of the working area in real time, and the detected light intensity data is transmitted to the single-chip microcomputer; in this embodiment, the intelligent lighting centralized control system is equipped with an illuminance meter.

[0035] In this embodiment, the dimming interface of the single-chip microcomputer is divided into two groups of dimming control units, which respectively control the lamps in two areas of the factory. Specifically, one group of dimming control units controls the working status of the lamps in area one, and the second group of dimming control units controls the working status of the lamps in area two; each group of dimming control units includes four dimming output ends, that is, the single-chip microcomputer has a total of eight dimming output ends; the eight dimming output ends of the intelligent controller are respectively connected to eight light drivers, and the light drivers adjust the brightness of the lamps connected to the light drivers according to the dimming signals transmitted by the single-chip microcomputer; the light driver is externally connected to a switch, which is used to control the start and stop of the light driver.

[0048] Furthermore, if Figure 3 As shown, the fault detection module includes a clock generator U1, a counter U2, a transistor Q1, resistors R1, R2, R3, R4, ordinary capacitors C1, C2, a polarized capacitor C3, ESD diodes D1, D2, ordinary diodes D3, D4, and an interface H1;

[0053] like Figure 4 As shown, in this embodiment, the dimming control process of the intelligent controller is as follows:

[0054] The intelligent controller determines the connection status of the external switch K1 and the external switch K2. If the external switch K1 is connected, the intelligent controller turns off all lamps; if the external switch K2 is connected, the intelligent controller adjusts the illumination of all lamps to 45% through the light driver;

[0055] If the external switch K1 is disconnected and the external switch K2 is also disconnected, the intelligent controller determines the lighting status of the first group of lamps and the second group of lamps according to the illumination detection data; the first group of lamps is the lamps in area one, and the second group of lamps is the lamps in area two; the illumination detection data is collected by the illuminance meter, and after the collection is completed, the illuminance meter transmits the data to the intelligent controller, and the intelligent controller converts the data into the lighting status quantity of the corresponding group and judges the lighting status at the same time;

[0056] The intelligent controller determines whether the light-on state quantity of one group of lamps is less than the light-off threshold value 1, and whether the light-on state quantity of the second group of lamps is less than the light-off threshold value 2. If the intelligent controller determines that the light-on state quantity of one group of lamps is greater than the light-off threshold value 1, the intelligent controller turns off one group of lamps; if the intelligent controller determines that the light-on state quantity of the second group of lamps is greater than the light-off threshold value 2, the intelligent controller turns off the two groups of lamps; the light-off threshold value 1 is the light parameter data set by the staff on the parameter setting screen to control the light-off of one group of lamps, and the light-off threshold value 2 is the light parameter data set by the staff on the parameter setting screen to control the light-off of the second group of lamps;

[0057] If the intelligent controller determines that the light-on state quantity of one group of lamps is less than the light-off threshold value 1, or the light-on state quantity of two groups of lamps is less than the light-off threshold value 2, the intelligent controller performs calculation processing on the light-on state quantity of one group of lamps, or the light-on state quantity of two groups of lamps according to the illumination detection value, the illumination setting value 1, and the illumination setting value 2; the illumination detection value is collected by the illuminance meter and transmitted to the intelligent controller, the illumination setting value 1 is set by the staff on the parameter setting screen as the light reference data of one group of lamps, and the illumination setting value 2 is set by the staff on the parameter setting screen as the light reference data of two groups of lamps;

[0058] After the processing is completed, the intelligent controller outputs one set of dimming control values, or two sets of dimming control values, and outputs the dimming control values ​​to the lighting driver in the corresponding area through the dimming output end of the dimming control unit of the intelligent controller, and automatically adjusts the illumination of the lamps in the area; the corresponding area for one set of dimming control values ​​is area one, and the corresponding area for two sets of dimming control values ​​is area two.
