Electronic tag is arranged on the wrist strap that inmate wears, and storage inside that personnel's essential information of preserving with server matches unique No. ID, and uniformly-spaced the time initiatively sends the data message of set form to read write line;

Read write line is arranged on the fixed position in region, and the data that reception electronic tag sends are also added signal strength values;

Repeater is arranged on the fixed position in region, connects Ethernet, the data that in energy receiving area, all read write lines send, and upload the data to management server by Ethernet;

The data that receive are carried out dissection process by management server, according in electronic tag, store No. ID, read write line positional information and receive the signal strength values of electronic tag data and time value, server database in the real-time definite region of the personal information of storing personnel's position.

Described electronic tag all comprises dormancy economize on electricity, power supply capacity detects and alarm detection function, and the time interval that initiatively sends data is adjustable.

Described rfid interrogator comprises the clock chip that precision is high, and the time synchronizes with top service device, has bi-directional communication modules, alarm detection module.

Described management server comprises data decryptor receiver module, Data Analysis processing module, the multiple display module of data memory module and result.

Radio RF recognition technology (Radio Frequency Identification, RFID) be a kind of wireless communication technology, can identify specific objective and read and write related data by radio signals, and without setting up machinery between recognition system and specific objective or optics contacts, it is a kind of senior automatic identification technology, utilize it to carry out contactless full duplex data communication by wireless radio frequency mode, realize the identification to target in kind.Principle as shown in Figure 1.

Advantage of the present invention is: RFID is combined with wireless sensor network and is applied in Prison staff indoor locating system, can make managerial personnel grasp in real time details and the number of each controlled area personnel under detention in prison, reduce the probability that criminal assembles a crowd to make trouble, the high-risk personnel under detention of secret monitoring, trace and the generation of the incident of violence that follows up, effectively prevent running away of personnel under detention, ensure to greatest extent managerial personnel and personnel under detention's personal safety.In addition, system can also realize number and periphery policeman's information on duty in automatic calculating appointed area, greatly reduces prison officer's working strength, can locate rapidly policeman's on duty position in the time running into accident.Meanwhile, can realize closely gate inhibition in conjunction with RFID technology, the all-purpose card such as personnel under detention, current consumption function in prison.System can also be combined with face identification system, gate control system, video monitoring system etc., can launch to provide convenient, efficient modernization means to every management work of criminal for prison, from truly realizing prison administration informationization.

Embodiment

With reference to accompanying drawing:

Indoor occupant wireless sensor network positioning system based on active RFID, it is characterized in that: be divided into the top section that the hard-wired underclad portion of data transmission network and main control system Data Analysis process software are realized, described underclad portion is by active electronic label, rfid interrogator and repeater, described top section operates on management server, the data that described underclad portion is uploaded are carried out dissection process and are stored database into, make personnel's positional information visual, and judge whether to occur abnormal conditions warning;

Electronic tag is arranged on the wrist strap that inmate wears, and storage inside that personnel's essential information of preserving with server matches unique No. ID, and uniformly-spaced the time initiatively sends the data message of set form to read write line;

Read write line is arranged on the fixed position in region, and the data that reception electronic tag sends are also added signal strength values;

Repeater is arranged on the fixed position in region, connects Ethernet, the data that in energy receiving area, all read write lines send, and upload the data to management server by Ethernet;

The data that receive are carried out dissection process by management server, according in electronic tag, store No. ID, read write line positional information and receive the signal strength values of electronic tag data and time value, server database in the real-time definite region of the personal information of storing personnel's position.

With reference to accompanying drawing 2, native system can be divided into lower floor's data transmission network hardware realization part and realize two parts with upper strata main control system Data Analysis process software.Wherein hardware components is made up of active electronic label, rfid interrogator and three parts of repeater, upper layer software (applications) part is to operate on management server, the data that lower floor is uploaded are carried out dissection process and are stored database into, make personnel's positional information visual, and judge whether to occur abnormal conditions warning etc.

Described electronic tag all comprises dormancy economize on electricity, power supply capacity detects and alarm detection function, and the time interval that initiatively sends data is adjustable.
