Description
Technical field
The utility model relates to the railway signals equipment field, is specifically related to the transponder message reading device, for be the portable set that the transponder message is read and writes, line side electronic equipment message is read.
Background technology
Present transponder message reads instrument and adopts the PC computer to add the design of peripheral circuit, volume weight is very large, distance is made troubles to personnel's maintenance work between the on-the-spot transponder, and present reader only shows original message data and user's message data, does not show the detailed parsing that current message comprises.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art, the transponder message reading device is provided, this device signalization conditioning unit and signal resolution unit, the signal condition unit can be resolved message transmissions to the signal resolution unit of transponder, show by the message display unit more afterwards, also realized simultaneously the parsing with the LEU equipment message, thereby the message that can be applicable to transponder and LEU equipment reads needs, and be formed centrally the closed loop inspection in final and the row control, guarantee the fail safe of driving.
The utility model purpose realizes being finished by following technical scheme:
A kind of transponder message reading device, be used for reading the message of transponder and line side electronic equipment, it is characterized in that: described device comprises that at least one is used for receiving antenna element, a signal condition unit, a signal resolution unit and a message display unit of described message, described antenna element is connected with described signal condition unit, described signal condition unit is connected with described signal resolution unit, and described signal resolution unit is connected with described message display unit.

The utility model has the advantages that: volume is little, lightweight, easy to carry, can quick and precisely read to write the transponder message and read LEU message, stored record greater than 5000, can derive message information by USB interface.
Description of drawings
Fig. 1 is theory diagram of the present utility model.
Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technical staff's of the same trade understanding:
Embodiment: as shown in Figure 1, transponder message reading device in the present embodiment is comprised of antenna element, signal condition unit, signal resolution unit, CPU processing unit, the CPU processing unit is comprised of memory cell, interface unit and message display unit, and the function of its various piece is specific as follows:
1, antenna element
Antenna element is fixed in the circuit board of message reading device, be set to be the oblong-shaped of independent annular by the printed board copper cash, be divided into transmitting antenna and reception antenna two-way, reception antenna is used for receiving the message signals of transponder or LEU equipment, transmitting antenna is used for providing energy to transponder, activates transponder circuit.Transmitting antenna and reception antenna are connected respectively to the signal condition unit, in order to carry out message switching with the signal condition unit.
2, signal condition unit
When needs read the message of transponder, the generation of the transponder pumping signal of 27.095MHz is realized in the signal condition unit, this moment, transponder was sent to the signal condition unit with message by the reception antenna in the antenna element, the signal condition unit carries out detection and conditioning to the FSK signal of the 3.9MHz/4.5MHz that antenna element receives, converts digital square-wave to and transfer to the signal resolution unit to resolve.
When needs read the message of LEU equipment, the signal condition unit received the 8M carrier signal that LEU equipment sends and also carries out detection and processing, was converted to afterwards the DBPL signal and delivered to the signal resolution unit and resolve.
3, signal resolution unit
1023 bit data streams (through the message signals after the signal condition cell translation) that the signal resolution unit is responsible for that the signal condition unit is sent here carry out substep according to eurobalise message coding decoding agreement FFFS resolves, and the message display unit that its analysis result is delivered to the CPU processing unit by the RS232 interface shows.
4, CPU processing unit
CPU processing unit hardware comprises memory cell, interface unit and message display unit, memory cell is connected to record transponder or the next message data of LEU device transmission with signal condition unit and signal resolution unit, the message that the message display unit receives in order to demonstration, interface unit is in order to be connected with remaining element or external equipment.The CPU processing unit has USB2.0 main interface, LCD interface, 4 wire resistive touchscreen interfaces, a plurality of serial ports, the application program that adopts Qt to write writes message, has realized that human-machine operation, packet storage, the message with the user imports and exports, software upgrading, date are revised, the record queries function.
Present embodiment is in the specific implementation: described signal condition unit comprises the generation of 27.095MHz signal, filter circuit, detecting circuit, comparison circuit, power amplifier, power amplification control circuit.The signal resolution unit comprises the FPGA circuit, produces to finish the FFFS protocol analysis and to write the message control waveform.The CPU processing unit comprises that memory cell is used for the stored messages record, interface unit adopts one tunnel USB interface to be used for connecting external USB flash disk and stores.The message display unit adopts a liquid crystal touch screen control circuit to be used for carrying out human-machine operation with the user.
