A monitoring method of a real-time monitoring system based on radio frequency identification technology

Abstract

The invention provides a real-time monitoring system based on a radio frequency identification technology and a monitoring method of the real-time monitoring system. The real-time monitoring system comprises at least one anti-theft host, at least one anti-theft tag and at least one group of low-frequency transmitting antennas, wherein the anti-theft host is used for monitoring the state of the anti-theft tag in real time; the anti-theft tag responds to the real-time monitoring of the anti-theft host; and the low-frequency transmitting antennas are used for establishing a low-frequency electric field monitoring area. According to the real-time monitoring system and the monitoring method provided by the invention, by virtue of the wireless radio frequency identification technology, a monitored article can move freely within the monitored area, and when the anti-theft tag is illegally removed, maliciously damaged or carried away from the monitoring area, an anti-theft alarm is triggered immediately, and thus the monitoring is strong; and moreover, double-frequency communication is carried out between the anti-theft host and the anti-theft tag by virtue of low-frequency signals and ultra-high-frequency signals, so that the antijamming capability is strong, and the security and stability are good.

Description

technical field [0001] The invention relates to a monitoring method of a radio frequency identification technology-based real-time monitoring system, in particular to a radio frequency identification technology-based real-time monitoring system and a monitoring method thereof. Background technique [0002] In modern commercial activities, the form of open vending is quite popular, providing consumers with a free and pleasant shopping environment, but open vending is not conducive to the supervision of commodities, and incidents of commodity theft often occur, bringing great losses to merchants. At present, there are two main anti-theft methods used by merchants: one is to fix EAS tags or similar acousto-magnetic tags on the products, and install close-range access control detection devices at all entrances and exits. Normally, the sold products will be taken away during settlement. Remove the EAS tag or demagnetize the magnetic tag, but if the EAS tag on the product is remov...

[0002] In modern commercial activities, the form of open sales is quite popular, providing consumers with a free and pleasant shopping environment, but open sales is not conducive to the supervision of goods, and theft of goods often occurs, which brings great losses to merchants

At present, there are two main anti-theft methods used by merchants: one is to fix EAS tags or similar acousto-magnetic tags on the products, and install close-range access control detection devices at all entrances and exits. Normally, the sold products will be taken away during settlement. Put down the EAS tag or demagnetize the magnetic tag, but if the EAS tag on the product is removed or damaged with a staple remover in the store, the alarm will not be triggered when the product passes through the access control, and the monitoring is weak

The second is to use a telescopic lanyard type anti-theft device with a built-in conductive circuit. When the device is directly removed from the product, an open circuit alarm will be triggered. However, the length of the anti-theft lanyard is limited and it is not easy to move the product. It is mainly suitable for monitoring product samples. And it needs someone to take care of it, it is impossible to realize the real open sale, and the consumer experience is not good
