Energy-saving safety door lock control device
The invention discloses an energy-saving safety door lock control device. The energy-saving safety door lock control device comprises a wireless communication module, a memory, a single chip microcomputer, a door lock operating device, a normally closed relay, an infrared monitoring module and an audible alarm module. The wireless communication module is used for receiving door lock verification information; the memory is used for storing user information; the infrared monitoring module is used for monitoring whether people stays outside a door for a long time or not; the single chip microcomputer is used for comparing the door lock verification information with the user information to obtain compared results, outputting a power-off control signal after a user goes out and inversely locks the door, and outputting an alarm trigger signal when people stays outside the door for certain time exceeding a preset threshold value; the door lock operation device is used for operating a door lock according to the compared results; a coil of the normally closed relay is used for receiving the power-off control signal, and a contact point switch of the normally closed relay is in series connected in a power supply loop of a household electrical appliance; and the audible alarm device is used for giving voice alarm while receiving the alarm trigger signal. The energy-saving safety door lock device provided by the invention can avoid electric energy waste, and improves the safety.
