INTELLIGENT ELECTRIC-SHOCK PROTECTION SOCKET BASED ON PYROELECTRIC INFRARED DETECTION

摘要

An intelligent electric-shock protection socket based on pyroelectric infrared detection comprises a casing (100), jack groups arranged on the casing (100), a pyroelectric infrared sensor (10), a detection switch (20), a relay output module (30), a control module (40) and a power supply module (50). Each jack group comprises a live wire jack (70) and a zero line jack (60). The pyroelectric infrared sensor (10) is used for detecting the human existence information around the socket. The detection switch (20) is used for detecting the plug insertion information of the jack groups. One end of the relay output module (30) is connected with the control module (40), and the other two ends are respectively connected with the live wire jacks (70) and the zero line jacks (60) of the jack groups. The control module (40) is used for receiving and processing the human existence information and the plug insertion information. When a plug is inserted into the live wire jack (70) and the zero line jack (60) of the jack group at the same time, and no human is around the socket, the control module (40) controls the relay output module (30) to switch on the power supply of the jack group, otherwise controls the relay output module (30) to cut off the power supply of the jack group. The power supply module (50) is connected with all the modules and devices. The socket can avoid electric-shock accidents and guarantee personal safety.
