Module is sent to be electrically connected respectively with the first controller, the reception of wireless signals module, alarm module are electric with second controller respectively
Connection, the signal that first controller detects according to the distance measuring sensor and infrared sensor send mould by wireless signal
Block sends alarm signal, and the alarm signal that the second controller receives according to reception of wireless signals module controls alarm module report
It is alert.
Further, the test side includes substrate, the distance measuring sensor, infrared sensor, the first controller and nothing
Line signal transmitting module is fixedly installed in the substrate, and the substrate is installed on the inwall of refrigerator, and the distance measuring sensor is used for
Detect the distance of refrigerator doors.
Further, the substrate backside is provided with magnetic adsorbing block, and the substrate adsorption is in the inwall of refrigerator.
Further, the distance measuring sensor is ultrasonic distance-measuring sensor, and alarm module is buzzer.
Preferably, the wireless signal sending module and reception of wireless signals module are Zigbee module.
Further, first controller exceeds predetermined value and in infrared biography in the distance signal that distance measuring sensor detects
Sensor does not detect the output alarm signal that is delayed after infrared signal.
The advantages of technical scheme provided by the utility model, is：Distance using distance measuring sensor detection refrigerator doors is sentenced
Disconnected refrigerator door open-close state, and being detected with reference to infrared sensor to human body, it can avoid after user opens refrigerator doors
Long period finds article and causes false alarm, improves the accuracy of alarm.Carried out additionally by the warning end of wireless connection
Alarm, can avoid user away from after refrigerator can not audible alarm sound the problem of, the warning end of wireless connection is easy to be in the layout of room
Interior multiple places, alarm range is expanded, strengthened practicality.
