System and method of handheld terminal of outdoor escorting device to simultaneously control a plurality of electronic foot fasteners

Abstract

The invention discloses a system and method of a handheld terminal of an outdoor escorting device to simultaneously control a plurality of electronic foot fasteners. The method comprises the following steps: the electronic foot fastener broadcasts and sends a network access message to the handheld terminal in a wireless manner; the handheld terminal allocates a unique time slot to the electronic foot fastener within a communication period, and the handheld terminal replies a network access agreement message to the electronic foot fastener, wherein the network access agreement message carries a communication time length, a working time slot of the foot fastener and accurate clock information of the handheld terminal; the electronic foot fastener synchronizes its own clock according to the accurate clock information of the handheld terminal after receiving the network access agreement message; the electronic foot fastener performs normal work on the time slot in a subsequent working period according to a period time length and time slot information specified by the handheld terminal, and the above steps are repeated to access other electronic foot fasteners working at the same time to perform normal work. by adoption of the method disclosed by the invention, the demands of escorting a plurality of escorted people by escorting personnel at the same time in the field of public security are satisfied.

Description

technical field [0001] The invention relates to the field of public security, in particular to a system and a method for simultaneously controlling multiple electronic foot buttons by a handheld terminal of an outbound escort device. Background technique [0002] At present, the outbound escort system mainly includes three parts, the handheld terminal, the electronic foot buckle, and the geographic location display and distance measurement software control and control platform. In this system architecture, the handheld terminal and the electronic foot buckle need to be paired for use. The usual method is: [0003] The handheld terminal and the electronic foot button send and receive messages one-to-one in the wireless communication frequency band they use, and realize pairing and work through the defined communication protocol; [0004] The disadvantage of this approach is: when a group of escorts escorts multiple escorts at the same time, the handheld terminal needs to cont...

Problems solved by technology

[0004] The disadvantage of this approach is: when a group of escorts escorts multiple escorts at the same time, the handheld terminal needs to control multiple electronic foot buttons at the same time. The handheld terminal in the current electronic foot button system can only be connected to one electronic foot button at the same time. Communication, cannot meet this usage scenario
