The present invention can be used in underground, tunnel, cave, mine down hole, in particular long and large possible curvy confined space; and capable of sending paging instruction to tracked object through system.
Description
Technical field
Patent of the present invention relates to the system of using radio frequency recognizing technique tracking target, more specifically, relates to the system of enclosure space using radio card real-time follow-up target that grow up in subway, tunnel, cavern, down-hole, mine, particularly coal mine roadway etc., may be crooked.
Background technology
(Radio Frequency Identification RFID) is a kind of non-contacting automatic identification technology to radio RF recognition technology, and its ultimate principle is to utilize radiofrequency signal and space coupled transfer characteristic, realizes being identified the automatic identification of object.
Typical radio-frequency recognition system is made up of radio-frequency card, frequency read/write, computer management device three parts usually.Radio-frequency card is mounted in and is identified on the target (or claiming object, object), or is carried by the people, and storage is identified the electronic installation of target relevant information, and the information in the storer that radio-frequency card comprises can be carried out the noncontact read/write by frequency read/write; Frequency read/write is the equipment that utilizes radio-frequency technique to read radio-frequency card information or information is write radio-frequency card; The radio-frequency card information that frequency read/write is read is managed by the computer management device.
As shown in Figure 1, the course of work of modal radio-frequency recognition system is such: frequency read/write 2 emitted energy in a zone forms electromagnetic field, send the data that store after detecting this signal during this zone of radio-frequency card 1 process, the signal that frequency read/write 2 received RF cards 1 send, after the decoding data are issued computer management device 3,3 pairs of data of computer management device are further handled to reach the purpose of Target Recognition.
Different radio-frequency recognition systems has the technical characterictic that varies because of the difference of its application need.System for the remote identification of needs, general radio-frequency card adopts active mode, frequency of operation adopts hyper band (UHF) or higher microwave frequency band, be 300Mhz～3Ghz or higher frequency scope, typical frequency of operation is about 315Mhz, 433Mhz, 915Mhz, 2.4Ghz and 5.8Ghz.
In the field that long-range radio-frequency identification is used, there is a class to have similar geographic entity, as subway, tunnel, cavern, down-hole, mine, particularly coal mine roadway: the space that their cover is very long-range, can reach tens kilometers as colliery underworkings extended line; And the width in space generally has only several meters with highly relative very little; And these space structure complexity, have a lot of layerings, fork and the anxious slow bent angle that differs.
Has the enclosure space of growing up of above-mentioned geographic entity, particularly at the colliery underworkings, realization is to being identified target, gamut real time position monitoring as coal mine down-hole personnel, vehicle and equipment, it is a very exigence, if can grasp the particular location of all miners under the coal mine in real time, this is to daily production scheduling and security control under the coal mine, and can both provide vital effective means to the colliery emergency relief.Yet, use existing REID, mthods, systems and devices, can not realize above-mentioned target.
At first,, require system must reduce frequency read/write quantity as far as possible, otherwise will greatly reduce, even eliminate the possibility of system applies for reducing system complexity and application cost.Under this prerequisite, to realize the gamut that is identified target is monitored in real time in the above-mentioned curved space of growing up very much, just require the one side frequency read/write enough far away to the reading/writing distance of radio-frequency card, requirement simultaneously can realize the transmission of radiofrequency signal in the curved space, and radiofrequency signal, can only be along the straight line transmission in air, so under present technical conditions, can not achieve the above object.
As mentioned above, to realize the gamut that is identified target is monitored in real time in the above-mentioned curved space of growing up very much, require frequency read/write enough far away to the reading/writing distance of radio-frequency card, at this moment, the position that is identified target be determined receive be identified target in the read-write scope of frequency read/write of corresponding radio-frequency card information, because of this distance enough far, therefore the position that is identified target can only be judged in a very large scope, can not realize being identified the more accurate judgement of target location, this greatly reduces the validity of system applies, then can not reach the purpose of Target Recognition sometimes substantially.
In existing radio-frequency recognition system, radio-frequency card is not accepted the paging instructions of system's issue and can not paging instructions be showed in modes such as diode displaying, thus do not use radio-frequency recognition system as a kind of to being identified the command means of target.
