A kind of prison indoor locating system based on WiFiTechnical field
The present invention relates to wireless location monitoring technique field, prison, especially relate to a kind of prison indoor locating system based on WiFi.
Background technology
At the prison in environmental monitoring, positional information plays important effect, grasps the positional information of related personnel timely and accurately, contributes to improving safety management level, simplifies prison administration work.Current global positioning system (GPS, GlobalPositioning System) is the most common way obtaining outdoor environment positional information.In recent years, along with the fast development of wireless mobile telecommunication technology, A-GPS (the Assisted Global Positioning System) locate mode that GPS and cellular network combine obtains application gradually in emergency relief and various position-based service (LBS, Location-Based Services).Gps satellite is located, and needing in relatively spacious, that skyscraper is not intensive place could more accurate location, indoorly cannot to use and power consumption is higher.But when the receiver of GPS is when the intensive city of housing-group or office work, because signal strength signal intensity is subject to the impact of building and large high attenuation, cause that positioning precision is low even can not complete location, the location of GPS realizes must by repeatedly Internet Transmission (can reach at most 6 one-way transmissions), and this is occupied concerning being tantamount to a large amount of air resource operator.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned deficiency of the prior art, a kind of prison indoor locating system based on WiFi is provided, the present invention is positioned by WiFi network, the restriction of GPS in building dense or indoor application can be made up, expand application industry and the scope of positioning service, improve positioning precision, reduce lower deployment cost, improve utilization rate of equipment and installations, strengthen the rescue ability of solution of emergent event, significant in monitoring management at the prison.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, a kind of prison indoor locating system based on WiFi, is characterized in that: comprise the service end being arranged on police service monitoring room and the client being arranged on prison; Described service end comprises Web server, database server, location-server and router, and the Web server of described service end, database server, location-server and router are interconnected by local area network (LAN); Described client is the mobile terminal for monitoring location convict; The router of described service end is connected by wireless WiFi net with the mobile terminal of client.
In the present embodiment, described mobile terminal is portable mobile termianl, notebook computer, inmate monitor dress electronic equipment any one.
As shown in Figure 2, in the present embodiment, described monitoring dress electronic equipment comprise microprocessor and be connected with its input for identify convict's identity identification module, for monitor convict's person situation physiological parameter sensors, for monitor prison environment information environmental parameter sensor, for detecting the acceleration transducer of convict's action message and gravity sensor and the communication module for following the trail of convict present position, described microprocessor is also connected with power module, memory module and display module.
In the present embodiment, described physiological parameter sensors comprises blood pressure detecting transducer, heart rate detection transducer and temperature check transducer; Described environmental parameter detector comprises temperature sensor, humidity sensor, vibrating sensor, gas detection sensor, noise measuring transducer and soaks one of transducer or wherein two or more arbitrarily sensor combinations.
In the present embodiment, described communication module is wifi module.
As shown in Figure 1.The Location Request of service end primary responsibility location Calculation and response terminal.Consider based on load balancing, the Web server of response position request is separated with the location-server running location, and data exchange ways adopts the data exchange ways that client is identical with Web server.Client depends on concrete object, and primary responsibility gathers the wireless signal strength of periphery AP, and submits signal characteristic to service end, and server uses the signal characteristic of client collection to position, and obtains the location estimation of mobile terminal.
The collecting device of client is generally be worn on convict's wearable device with it (such as wrist strap), or aim at the portable mobile termianl of convict's customization, its internal circuit structure is the structure of above-mentioned monitoring wearing described in electronic equipment, transducer collects physiology, the information such as action and living environment of convict, and by Microprocessor S3C44B0X process, to be finally sent to by wifi network by communication module in the router of service end and finally to realize wireless monitor and locate.
Above-described embodiment is preferred embodiment of the present invention; it is not the restriction to technical solution of the present invention; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of patent of the present invention.
