Background technology
Ground trackside electronic unit LEU is the important component part of CTCS-2/3 level train operation control system ground installation, instrument and the passage of train control center and transponder interactive information, the train control center at station sends to the information of LEU by the S interface of LEU, comprise station train route message, circuit temporary speed limitation message and requesting state information, LEU is by serial communication interface and TCC equipment connection, message from TCC is sent to active balise continuously, thus realize sending variable information to mobile unit, when the data invalid of LEU and TCC communication failure or reception, LEU sends acquiescence message to active balise.
The ICE equipment Inspection LEU that the domestic detection to LEU at present can only be carried by LEU is to the break-make of train control center, transponder telecommunication cable, cannot judge message whether normally send and output waveform whether correct, by range estimation, the detection of LEU at ordinary times can only check whether equipment exists obvious outward appearance damaged, for the detection never practicable method of physical characteristic.
If on-the-spot LEU device fails, electricity business operator on duty does not have means of testing effectively to detect reason, can only wait for that LEU indoor equipment changed by higher level department complete machine, the time of this process need at substantial, now reduction of speed travels by train, after administering section by fault LEU, can resume operation, cause great loss to train operation.
Therefore study and a set ofly can detect LEU operating state, outgoing message content, equipment that interface waveform is correct is very necessary.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the present invention is to provide a kind of LEU tester, effectively detects LEU operating state, outgoing message content and interface waveform and graphic software platform.
Its technical scheme solved is, comprise LEU message read module, spectrum measurement module, cable on off test module, main processing block, memory module, display module, function button, test pencil interface, battery and LEU tester shell, described LEU tester shell has the function button be connected with main processing block, LEU tester shell is provided with display module, LEU tester shell is provided with test pencil interface, LEU message read module, spectrum measurement module, cable on off test module, memory module is connected with main processing block respectively with display module, LEU message read module, spectrum measurement module, cable on off test module, memory module, display module is all connected with battery with main processing block.
The present invention effectively detects LEU operating state, outgoing message content and interface waveform and graphic software platform, and detects the break-make of LEU tester and transponder communication cable, adopts Portable hand mode, easy to use, quick, easy to operate and freedom from repairs.
