The invention discloses an outdoor LEU test system and an implementation method, the outdoor LEU test system comprises an industrial control computer, an LEU communication interface unit, a photoelectric conversion module, a transponder read-write tool, an active transponder, a controllable power supply and a switching recovery relay, a data port of the industrial control computer is connected to the photoelectric conversion module through the LEU communication interface unit; and the photoelectric conversion module is connected with an S interface of the tested outdoor LEU; meanwhile, the industrial control computer is connected with a transponder read-write tool, and the transponder read-write tool reads messages sent by the active transponder in a wireless mode; and the active transponder is connected with a C interface of the tested outdoor LEU, and the tested outdoor LEU is connected with a simulation load. According to the invention, the real working state of the outdoor LEU is simulated, the function and the performance of the outdoor LEU are tested, the test efficiency and the measurement accuracy are improved, the labor intensity is reduced, and the consistency and the accuracy of the test are ensured.
Description
technical field [0001] The invention relates to a railway signal equipment detection application technology, in particular to an outdoor LEU test system and a realization method. Background technique [0002] The outdoor LEU (Lineside Electronic Unit, ground electronic unit) is an important part of the ground equipment of the transponder transmission system, which can periodically receive transmission messages from external equipment (ground train control center, etc.) After the message information is processed by the circuit signal, it is converted into a C interface signal and sent to the transponder device, which solves the problem of long-distance transmission. After the outdoor LEU has been used in the field for a period of time, it is necessary to regularly perform functional tests on each module. [0003] At present, the test of each module in the outdoor LEU is done manually, which has low efficiency, large test errors, high labor intensity, and a single test range....
