Description

A kind of personnel location system
Technical field
The present invention relates to be positioned at wireless sensing field, and in particular to a kind of personnel location system.
Background technology
The domestic patent of invention related to personnel location system or method nearly hundred, be related to RFID, Zigbee, Wi-Fi, The multiple technologies such as UWB system and based on a variety of location technologies such as coding, field strength, phase calculation.These alignment systems Basic framework is fixed deployment locating base station, and personnel carry positioning label, and locating base station receives the positioning carried from personnel The information of label, is identified and positions according to information such as its field strength, phase, sequence label codes, recognizes that the calculating with positioning is led to Cross central server completion.This framework is suitable for the scene such as colliery, factory of fixed environment, high density of personnel, this framework Shortcoming be:(1)Deployment density of the raising of its positioning precision dependent on increase locating base station, because the networking between base station is more That it needs external power source to power by wire transmission modes such as optical cable, buses, cause improve positioning precision needed for investment, line The quantities such as cable erection, engineering construction cycle become rapidly big.(2)Positioning label degree of intelligence entrained by personnel is low, only exists The manager at center can see the situation of personnel, and positioning label-carrier can not learn the position of itself and periphery Confidence ceases, it is impossible to realize the function of navigation, help can not be provided to the personnel for getting lost or be unfamiliar with surrounding scene, to entering or connecing The personnel of nearly similar " forbidden zone " also can not real-time informing.(3)The calculating of all about positional information all relies on central server, clothes Once device lost contact of being engaged in or machine of delaying, system is at a standstill.
For example, Chinese patent CN102523621A discloses a kind of Mine Personnel Positioning System, it by ground monitoring center, Transmit base station, optical fiber, gateway node, bus, beacon node, training node and mobile node composition.Beacon node is in tunnel Laid by block, personnel carry mobile node, mobile node reads the signal of beacon node and to the beacon node that receives Location information is handled, and is uploaded to ground monitoring center and its station-keeping mode data progress matching primitives, realizes positioning;Instruction Practicing node is used to measure, obtain, correct station-keeping mode data.But, the complexity of (1) system first is high, by up to 8 Part is constituted;(2) structure of its subsystem needs to lay the wire transmission medias such as optical fiber, bus, and quantities is big and is difficult to quick Deployment, is difficult to be applicable for the mobile environment or adverse circumstances for being not easy to set up cable;(3) furthermore its mobile node positioning according to Rely the matching primitives at ground monitoring center, once system and ground monitoring center lost contact, terminal can not then realize positioning, (4) its The degree of intelligence of mobile node is low, and terminal does not possess local processing and display capabilities in real time, and the carrier of mobile node can not see To oneself position, enter without possessing the ability of navigation, once it is lost also useless even if mobile node is carried;(5) it is positioned The raising of precision needs to rely on training node and gathers signal to each block in tunnel, establishment model data, complex operation and Positioning precision easily by the humiture being continually changing in site environment, block, electromagnetic environment is influenceed.In summary, the system Complexity is high, mobility is poor, the characteristics of not possessing rapid deployment.Accordingly, it is desirable to provide it is a kind of it is more simple, reliable, quick, The technology of intelligence, to realize rapid, effective use to location information.
