Abstract

The invention provides a system and method for detecting closing of a cabinet door. The system is characterized in that a first distance sensor and a second distance sensor are arranged at different positions on a cabinet body respectively so as to monitor a first distance signal and a second distance signal of the cabinet door in the target direction respectively, wherein in the normal closing process of the cabinet door, the first distance signal and the second distance signal change according to preset reference change characteristics, the first distance signal and the second distance signal meet a preset linear relation, and when the change characteristics of the first distance signal and the second distance signal conform to preset reference change characteristics and the first distance signal and the second distance signal meet the preset linear relationship, it is determined that the cabinet door is closed, otherwise, it is determined whether the cabinet door is in an open state, and it is determined that external personnel cheat the lock at the current moment, and an alarm signal is generated. According to the system and the method for detecting the closing of the cabinet door, the safety of the door lock of the container can be improved, the theft rate is reduced, and the loss of a merchant is reduced.

Description

technical field [0001] This specification relates to the technical field of unmanned retail, in particular to a system and method for detecting the closing of cabinet doors. Background technique [0002] With the rapid development of smart retail, products such as unmanned containers are becoming more and more popular. Unmanned containers have a strong demand for anti-spoofing locks. After successful spoofing of locks, external personnel may not be detected by the system when stealing or replacing items after successfully defrauding the lock, resulting in risks. Most of the existing unmanned containers adopt the electromagnetic lock scheme, and the open / close state of the door is identified through the magnetic reed switch (reed switch), so as to realize the functions of door closing detection and automatic locking. That is, a magnetic reed switch is set on the cabinet body, and a permanent magnet is set on the cabinet door. When the permanent magnet is close to the reed s...
