Problems solved by technology

GPS satellite positioning requires more accurate positioning in relatively open places where high-rise buildings are not densely populated. It cannot be used indoors and consumes a lot of power.
However, when the GPS receiver works in a city with dense buildings or indoors, the signal strength is greatly attenuated due to the influence of buildings, resulting in low positioning accuracy or even failure to complete positioning. GPS positioning must be transmitted through multiple networks (up to 6 unidirectional transmissions), which is tantamount to the occupation of a large amount of air resources for operators

Abstract

The invention discloses a prison indoor positioning system based on WiFi. The system is characterized in that a service end in a police service monitoring chamber and a client end in a prison are included; the service end comprises a Web server, a database server, a positioning server and a router, and the Web server, the database server, the positioning server and the router at the service end are connected through a local area network; the client end is used for monitoring and positioning mobile terminals of prisoners; the router at the service end and the mobile terminals of the client end are connected through a wireless WiFi network. According to the system, the WiFi network is used for positioning, limitations caused when GPS is applied in dense buildings or in rooms can be eliminated, the application industry and range of positioning service are widened, positioning precision is improved, deployment cost is lowered, the equipment utilization rate is improved, rescue ability for dealing with emergencies is improved, and the system plays an important role in prison monitoring and management.

Description

technical field [0001] The invention relates to the technical field of prison wireless positioning and monitoring, in particular to a WiFi-based prison indoor positioning system. Background technique [0002] In prison environment monitoring, location information plays an important role. Timely and accurate grasp of the location information of relevant personnel will help improve the level of security management and simplify prison management. At present, the Global Positioning System (GPS, Global Positioning System) is the most common way to obtain the location information of the outdoor environment. In recent years, with the rapid development of wireless mobile communication technology, the A-GPS (Assisted Global Positioning System) positioning method combining GPS and cellular network has gradually become more and more popular in emergency rescue and various Location-Based Services (LBS, Location-Based Services). got applied. GPS satellite positioning needs to be relati...
