Embodiment Construction

[0023] The technical solutions of the various embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] Such as figure 1 , figure 2 As shown, the monitoring system for persons with limited activity range includes two parts: the ankle node and the gateway node. Both the ankle node and the gateway node use the CC2530 module as the main control chip. The gateway node is used as the signal receiving node, and the ankle node is used as the signal transmitter. node. The anklet node worn by the monitored person communicates regularly with the gateway node, and the status informatio...

Abstract

The invention relates to the field of alarm equipment, and particularly relates to a supervision system for personnel with limited motion ranges. The system comprises a signal emission node and a signal receiving node, wherein the signal emission node is used for being fixed on the personnel with limited motion ranges, and is used for transmitting a radio frequency signal to the signal receiving node; the signal receiving node obtains an RSSI value of the radio frequency signal after receiving the radio frequency signal; and if the RSSI value is not in the prestored RSSI threshold range of the signal receiving node, an alarm signal is emitted. The supervision system for the personnel with the limited motion ranges, which is disclosed by the invention, achieves an automatic alarm function that the monitored person is broken away from the monitored area through the internet of things; and the defect that a video monitoring system cannot automatically alarm is overcome.

Description

technical field [0001] The invention relates to the field of alarm equipment, in particular to a supervision system for persons with limited range of activities. Background technique [0002] Restricted scope of activities refers to people's courts, people's procuratorates, and public security organs restricting criminal suspects and defendants from leaving their residences or designated residences within a specified period of time during criminal proceedings, and monitoring their behavior and restricting their personal freedom. A coercive measure. Currently, video monitoring is widely used at home and abroad. This monitoring method has some disadvantages. Not only does the video monitoring equipment consume a lot of power, but also the electronic camera is inconvenient to install and debug. When the monitored person has an abnormal situation such as escape, the video surveillance cannot realize timely and automatic alarm, and there are blind spots in the surveillance. The...
