Detailed ways

The utility model is an office lighting control system, as shown in Figure 1, comprising public LEDs, deck LEDs, and a public LED drive module for performing on, off or adjusting the brightness of the public LEDs, and for performing on, off or adjusting The deck LED drive module of the deck LED brightness, the main control module used for data processing, the human body pyrolysis detection module used to detect whether there are people, the brightness detection module used to detect the brightness of office lighting, the main control module includes public LED control unit and deck LED control unit. The public LEDs shown are installed in public areas of offices, such as corridors, and each office can be controlled by a public LED driver module. The deck LED is installed above the employee deck, and several adjacent decks can share one deck LED. The human body thermal release detection module in the corresponding area is used to detect whether there is someone in the area. Each deck The LED corresponds to one LED driver module of the deck, and each LED driver module of the deck is connected with an independent small unit in the LED control unit of the deck, and has the independent small unit for data processing, and the independent small unit can be a comparator circuit. The public LED driver module and the deck LED driver module are delay dimming circuits, and the delay dimming circuit sets each time as 30 seconds, that is, each time when brightening or dimming the light, it completes the process from dark to dimming. It takes 30 seconds to complete from bright to dark, so as to reduce the damage to human eyes caused by sudden changes in light.

The human body pyrolysis detection module is a pyrolysis infrared human body sensor, which is used to detect the existence of the human body. The brightness detection module is a circuit composed of phototransistors to detect the intensity of ambient light. Connect to the input terminal of the LED control unit. That is, only when the human body pyrolysis detection module detects that there is a person, the detection data of the brightness detection module is input into the deck LED control unit for data processing. The card holder LED control unit processes and converts the signal received from the human body pyrolysis detection module, and then transmits the control signal to the card holder LED driver module through its output terminal, and then the card holder LED driver module controls the card holder LED. Adjust the brightness, or turn on and off the deck LED. When the presence of people is detected, the deck LED control unit outputs a control signal to enable the deck LED drive module to turn on the deck LED. The LED control unit of the seat will compare the detection data of the brightness detection module transmitted from the human body pyrolysis detection module, and perform a comparison operation. If the brightness of the office is dark, it will output the control signal to the LED driver module of the card holder, and then the LED driver module of the card holder will Brighten the deck LED.

The control of the public LED is relatively simple. The public LED is controlled through the three preset scenes in the public LED control unit: long-closed scene at night, work scene, and lunch break scene. For example, after work, the public LED control unit outputs a signal to turn off the public LED to the public LED driver module, and the public LED driver module turns off the public LED. If someone is in the office during this time period, they can be turned on manually. The manual turn-on part is the same as the prior art , which will not be described in detail here. For example, during working hours, the common LED control unit outputs a signal to turn on the common LED to the common LED driver module, and the common LED driver module turns on the common LED. For example, during the lunch break, the common LED control unit outputs a signal for dimming the common LEDs to the common LED driving module, and the common LED driving module dims the common LEDs.

The utility model also includes a central controller, and the main control module is connected with the central controller through a communication unit thereon. The communication unit is a MESH network, and the MESH network is connected to the central controller in a relay manner through the MESH network on the main control module in the adjacent office.
