Description

Technical Field

[0001] The utility model relates to the field of electric control equipment, and particularly to an intelligent power-off control device when people leave. Background Art

[0002] At present, the power-off when people leave the dormitory adopts an infrared intelligent induction device, which is an automatic control product based on infrared technology. When someone enters the induction range, a special sensor detects the change of the human infrared spectrum and automatically turns on the load. As long as the person does not leave the induction range and is in a static state, the signal is disconnected. After the person leaves, the load is automatically turned off after a delay. When people arrive, the light comes on; when people leave, the light goes out. It is kind and convenient, safe and energy-saving, and shows more human care.

[0003] Such products cannot monitor the operating state during use, cannot detect electrical parameters such as line temperature, current, voltage, residual current, power consumption, and power consumption. They cannot real-time monitor the electrical load and cannot detect malicious loads. When a fault occurs in the infrared intelligent induction device, although people leave the dormitory, the electrical load continues to consume electricity, which is likely to cause accidents such as fires and poses a safety hazard, and is very inconvenient to use.
