In said S103, the control host receives and processes the detection result and detection information, converts the processing result into a control signal and sends it to the smart main light, and the specific operation is as follows:

If the trigger controller detects that there are people in the room and the luminance detector detects that the luminance value in the room is lower than the preset illuminance value, it will send a signal to control the smart main light to turn on. If the trigger controller detects that there are people in the room and the light The brightness detector detects that the luminance value in the room is higher than the preset illuminance value, and then sends a signal to control the shutdown of the smart main light; if the trigger controller detects that no one exists in the room, it sends a signal to control the shutdown of the smart main light.

The living room is a place where human beings carry out general activities and needs relatively soft and uniform light. Video lights and appropriately reduce the ambient light in the living room; the overall illuminance of the living room can be controlled at 20-40lx, and the optimal illuminance can be set to 30lx. The control process is as follows. First, the trigger controller will always detect whether there is anyone in the bedroom. If no one or everyone leaves the bedroom, keep all the smart main lights off. The smart main light here is the living room chandelier; In the living room, the luminance detector sends the luminance value in the living room to the control host, and the control host judges whether it reaches the preset illuminance value that meets human activities in the living room. The preset illuminance value can be set at 20-40lx, and the maximum The optimal preset illuminance value can be set to 30lx. When the preset illuminance value is reached, all living room chandeliers will be turned off; if the preset illuminance value is lower than the preset illuminance value, the living room chandeliers will be soft-started, and then the TV working status will be detected by the TV status detector; if the TV is not turned on, Then directly adjust the brightness of the chandelier to make the ambient illuminance reach 30lx; if the TV is working, it means that people are watching TV, then turn on the smart auxiliary light, which is a video light, and adjust the brightness of the chandelier at the same time to make the ambient illuminance reach 30lx. When the video light is turned on to supplement part of the illuminance, the brightness of the chandelier will be lower than when the TV is turned off, fully adapting to the environment required by human eyes to watch TV.

The bedroom generally needs uniform and weak light to create a quiet, comfortable and comfortable atmosphere. The illumination can be controlled at 10-20lx, and the optimal illumination can be set In addition, some people have the habit of reading at the bedside, so the control of the bedside lamp is essential. If someone enters the bedroom, the brightness detector will detect the brightness value in the bedroom and send the detection information to the control panel. Host, the control host judges whether the preset illuminance value that meets human activities in the bedroom is reached. The preset illuminance value is 10-20lx, and the optimal illuminance can be set to 15lx. When the preset illuminance value is reached, all bedroom dome lights and The bedside lamp is turned off; if it is lower than the preset illuminance value, softly start the dome light in the bedroom, and then detect whether there is anyone on the bed through the pressure detector under the mattress; If there is someone on the bed, turn on the bedside lamp, and at the same time turn on and adjust the brightness of the ceiling lamp in the bedroom to make the ambient illumination reach 15lx. At this time, because the bedside lamp is turned on to supplement part of the illumination, the brightness of the bedroom ceiling lamp will be lower than when there is no one on the bed, which is fully suitable for people. In addition, when a person lies on the bed and does not move for a long time (more than 1 minute), the trigger controller will not be able to detect people in the room, and will turn off all bedroom dome lights and bedside lights, which is in line with the need for the human body to sleep. lighting requirements.

The study room is generally required to have bright and soft light suitable for reading, and the characters can be easily recognized, but it should not be too bright to avoid glare. The general illuminance can reach 40-60lx, and the optimal illuminance can be set to 50lx; The ambient light needs to be lowered relatively behind the desk lamp. First, the trigger controller will always detect whether there are people in the study room. If no one or everyone leaves the study room, then keep all the bedroom ceiling lights and desk lamps off; And send the detection information to the control host, and the control host judges whether the preset illuminance value that meets human activities in the study is reached. The preset illuminance value is 40-60lx, and the best preset illuminance can be set to 50lx to reach the preset illuminance If the value is lower than the preset illuminance value, then the dome light in the study will be soft-started, and then the pressure detector on the seat will detect whether there is anyone on the seat; if there is no one on the seat, directly adjust the study room The brightness of the dome light makes the ambient illuminance reach 50lx; if there is someone on the seat, turn on the desk lamp, and at the same time turn on and adjust the brightness of the study dome light to make the ambient illuminance reach 50lx. It is lower when there is no one in front of the desk, which fully meets the needs of the human eye.

In the step S104, after the smart main light receives a control signal to turn on, the smart main light turns on the lamp by means of soft start.
