Abstract

A real-time following and positioning system of an indoor camera based on a Zigbee network comprises a positioning RFID (Radio Frequency Identification) tag for marking a target, an RFID reader-writer module connected with the positioning RFID tag, a Zigbee network environment for wireless positioning, and a camera holder for controlling camera following, wherein the RFID reader-writer module comprises an antenna, an RFID chip, a microcontroller and a Zigbee signal transmit-receive module; the Zigbee network environment comprises the Zigbee network and a positioning mater controller; the Zigbee network comprises a Zigbee wireless network consisting of a Zigbee network coordinator and Zigbee network nodes; the positioning mater controller comprises a communication interface module for receiving a Zigbee network environment signal, an embedded information processing platform and a camera holder executing mechanism control module; and the embedded information processing platform integrates an echo state network positioning algorithm based on an RSSI (Received Signal Strength Indicator) model. The system can solve the problems of lack of a special positioning system, a large positioning error, difficult real-time positioning and the like of the existing indoor camera.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network positioning, in particular to an indoor camera real-time tracking positioning system based on Zigbee network. Background technique [0002] Indoor camera positioning has a strong application background, especially the real-time follow-up feature of the camera. At present, there is no complete and feasible system and solution in the field of real-time tracking and positioning of indoor cameras, and more is realized by manual assistance. At present, some people refer to the GPS (Global Position System) positioning method, which uses the embedded GPS module for positioning. However, the positioning equipment with embedded GPS module often has the problem that the indoor signal is easily lost, or the mobile power supply is limited and cannot work normally, which makes GPS tracking and positioning ineffective. At the same time, when the indoor camera uses a GPS module, there are still...
