Abstract

The invention provides a load detection chip for commodity safety. The chip comprises a voltage control module which is configured to provide a power supply voltage for a load, a voltage monitoring module configured to be capable of monitoring a voltage value on a load, and and output module. A load detection chip is configured to be capable of outputting a safety signal through the output modulewhen the voltage value exceeds a set threshold. The invention designs the load detection chip, which is a detection chip for commodity safety and has the advantages of small size, light weight, high detection effect, stable work, high reliability and high dynamic response, and the commodity safety state is confirmed by monitoring the voltage on the load, so that the supervision and protection of the commodity are ensured. And switching of corresponding detection circuits can be realized, so that application in different scenes can be realized, and the application range can be expanded.

Description

technical field

[0001] The invention relates to the field of commodity anti-theft, in particular to the circuit design in the commodity anti-theft device. Background technique

[0002] Commodity anti-theft is an industry that has emerged with the development of society and technology. In the field of commodity anti-theft, there are many subdivisions, such as setting up anti-theft equipment at the entrance and exit of supermarkets or stores to detect whether commodities have been taken out of the place. This is usually EAS (also known as electronic article anti-theft system), which is one of the commodity security measures widely used in the large retail industry. Transmitter and receiver, when the transmitter sends out a signal with a specific frequency, the receiver receives this signal, and then generates a monitoring area, this anti-theft mode is usually called retail anti-theft or area anti-theft.

[0003] Exhibit anti-theft is a subdivision field different from EAS. Ex...
