Concrete structure, annexation to positioner describes below.
Fig. 3 is a positioning device structure schematic diagram two, and as shown in the figure, interface in the positioner and annexation can be divided into two parts.One be the RFID read module card reader-and the CPU of control unit module between interface, its function is to be responsible for the data message in the card reader in the RFID read module is passed to CPU in the control unit module, the order of CPU sends to card reader, and interface adopts 8 parallel-by-bit port communications; Another is an interface between the CPU of wireless data module and control unit module, its function is that CPU gives the wireless data module with the card reader data forwarding that reads, and can receive the operational order that ground-based computer is sent by cordless communication network from the wireless data module, interface adopts serial communication.Also promptly:
1, link to each other by interruptive port, FPDP between RFID read module and the control unit module, wherein:
The RFID read module carries out next step operation by interruptive port notice control unit module;
The control unit module by FPDP from RFID read module reading of data, by FPDP to RFID read module transmit operation order.
Further, can also link to each other by the enable port between RFID read module and the control unit module, the control unit module is carried out enable operation by the enable port to the RFID read module.
Concrete, in card reader-cpu i/f part, CPU and RFID read module adopt 8 parallel-by-bit IO port communications, and physical interface is:
8 IO parallel data mouth: CPU read the data of RFID read module by parallel port, and instruct to the transmit operation of RFID read module;
Enable Pin: thus CPU can carry out the purpose that enable operation is avoided the repetition reading tag and realized low-power consumption to the RFID read module;
Interrupt: when the RFID read module reads label information, can produce by this pin and interrupt, remind CPU to carry out next step operation.
2, link to each other by the serial ports that comprises TX pin, RX pin between wireless data module and the control unit module, wherein:
The control unit module sends data by the TX pin to the wireless data module;
The control unit module receives from the next operational order of wireless data module transmission by the RX pin.
Further, can also link to each other by the enable port between wireless data module and the control unit module, the control unit module is carried out enable operation by the enable port to the wireless data module.Concrete, CPU can receive and dispatch the data of label information by the enable operation of wireless data module is controlled the wireless data module.
Concrete, in wireless data module-cpu i/f part, CPU and wireless data module section adopt the serial communication operation, and physical interface is:
Enable Pin.CPU can carry out enable operation to the wireless data module;
TX (transmission): CPU sends label data information by this pin to the wireless data module;
RX (reception): CPU sends the associative operation that gets off by this pin reception ground-based computer and instructs.
Fig. 4 is a positioner data interaction implementing procedure schematic diagram, as shown in the figure, can comprise the steps:
If step 404,16 random codes of label check correct, then respond card reader, reply PC+EPC (the product electronics sign indicating number) information of self; If invalid, then ignore order;
After step 407, card reader read handle information, can carry out read-write operation to label, CPU is sent to label together with handle random code and read order, gets final product the user data area part (UID) of reading tag, and this part is needed ground of native system physics and chemistry digital information;
After step 410, wireless data module are received data message, be forwarded to ground-based computer automatically, finish.
In further implementing, the locate mode that adopts the RFID mode also exists if multiple users when computer sends information earthward simultaneously, might occur collision problem; When card reader is read a plurality of label simultaneously, need to consider that the label information (promptly nearest with card reader label information) with signal stiffness of coupling maximum screens, present software section lacks this function, haves much room for improvement; When many card reader read a label simultaneously, conflict phenomenon might appear, and cause the part card reader to read less than label information.Given this, also provide two kinds of settling modes in the embodiment of the invention, a kind of is to adjust transmitting power by positioning service, and a kind of is to carry out the power adjustment after positioner self is judged, describes below.
1, the control unit module can also be further used for after reading geographical location information, and the power adjustment in the identification of geographic location information identifies, and adjusts transmitting power to adjust read range according to this marking command RFID read module;
The RFID read module can also be further used for adjusting transmitting power according to the order of control unit module.
Concrete, the card reader chip self contains the transmitting power that changes, and regulates the function that reads distance.When laying the tunnel with passive label, then in advance the different label ID that put density in the tunnel are carried out erasablely distinguishing, be 5**** as the label ID at 5 meters intervals, the label at three meters intervals is 3****, just and this label 5,3 can be used as power adjustment sign.When terminal was read certain scope interior label, the order that the then automatic reading card device of CPU sends the change transmitting power changed the purpose that terminal reads distance to reach.The real-time read-only unique tags information of terminal, thereby pinpoint method have so just been realized in the different densities tunnel.

The label aspect, simple in structure, cheap because inclement condition under the coal mine adopts passive label, be convenient to a large amount of the laying and maintenance in mine.
Radio frequency part, according to communication distance and transmitting power, the relation formula between receiving sensitivity and the operating frequency:
[Lfs](dB)＝32.44+201gd(km)+201gf(MHz)
Lfs is a loss in the formula, and d is a transmission range, and the unit of frequency calculates with MHz.
By following formula as seen, radio wave propagation loss in the free space (also claim decay) is only relevant with propagation distance d with operating frequency f, and when f or d increase when being twice, [Lfs] will increase 6dB respectively.
The loss of following formula explanation radio wave propagation under free space:
Los＝32.44+201gd(Km)+201gf(MHz)
Los is propagation loss, and unit is dB, and d is a distance, and unit is Km, and f is an operating frequency, and unit is MHz.
Can calculate, read if want to carry out radio frequency under 900MHz, and read apart from being about 10 meters, the loss of required chip or module is that difference is about 38 between transmitting power and the receiving sensitivity.Under the adverse circumstances of tunnel, need the decay that also has signal of consideration, so also will select the antenna and the label of suitable gain.
The wireless transmission part can be selected novel TD-SCDMA (Time Division-SynchronousCode Division Multiple Access, TD SDMA inserts) module (abbreviating the TD module among the application as).This module transmission speed is fast, and stability is high, and it is big to carry data volume.On this basis, select for use suitable TD module can shorten the construction cycle of hardware, and improve the stability of system.
In the software design part, can use MCU (MicroControllerUnit, miniature control unit claim one chip microcomputer again) to control radio frequency and TD part.Radio-frequency module is made as polling mode, in case it receives id information, data can partly be sent to ground-based computer by TD.Finish if data send, radio-frequency part branch enters poll next time.
