Description

Technical Field

[0001] The utility model belongs to the field of railway auxiliary equipment. Background Art

[0002] With the increase in railway speed and the construction of high-speed railways, the number of EMUs in operation has increased year by year, and the number of ATP (Automatic Train Protection) on-board equipment installed has also doubled. Therefore, efficient and high-quality ATP maintenance is the basis for ensuring the safety of EMU operation. The management concept of ATPMIS (ATP on-board equipment management system) is to complete the full life cycle management of ATP with ATP resume as the center, that is, to manage a series of activities from ATP leaving the factory to scrapping, mainly including ATP type testing, operation maintenance, advanced maintenance, fault maintenance, software upgrade, parts replacement, operation deployment and scrapping.

[0003] The EMU track circuit reader (TCR) is part of the onboard equipment of the CTCS-2 / 3 level train control system. It consists of a TCR host installed in the ATP cabinet and a dual-channel receiving coil at the bottom of the EMU. The receiving coil receives the track circuit signal transmitted in the track, decodes it and sends it to the subsequent ATP equipment through the serial interface to realize the operation control of the EMU in the CTCS-2 / 3 level mode. The TCR equipment is a key technical equipment to ensure the safe operation of the EMU.

[0004] At present, there are two methods for TCR function testing in the on-board equipment workshop of the EMU: one is to install the TCR on the EMU and use a loop line or a portable coder to confirm the decoding function, which is the most commonly used detection method; the other is a TCR test device connected to the TCR host test interface to directly perform code detection on the TCR host. However, these two operation methods have the following problems: 1) In locations where there is no loop line, it is necessary to use a portable coder to manually send codes. The placement of the coder has many human factors, and there is a risk that the equipment quality acceptance cannot be effectively guaranteed; 2) When the rail is sent through a loop line, the loop line needs to be placed on the rail. The operation process is cumbersome, and when the operator is wiring at the bottom of the EMU, it is easy to cause personnel safety hazards. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model. It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.

[0029] When the EMU is in use and undergoing maintenance, the vehicle is parked on the rails in the depot; during advanced maintenance, the EMU is lifted up with a trench at the bottom to facilitate operators to replace parts and perform maintenance.

[0030] 1. When the EMU is parked on the rails, there are generally two ways to test the performance of the TCR main engine.

[0031] One is to use a wireless code transmitter with a TCR test device, such as Figure 1 As shown, the TCR test device is connected to the TCR host, the remote control encoder sends the track circuit signal, the mechanical induction coil connected to the TCR host senses the signal sent by the encoder, and the performance of the TCR host is judged based on whether the light on the TCR host is consistent with the track circuit signal sent by the encoder below.

[0032] The second is to use a loop line to be arranged on the rails or to use a code rod to be placed on the rails, such as Figure 2 and Figure 3 As shown, it is located below the mechanical induction coil and sends the track circuit signal to the loop line or through the coding pole through the ground coding device. The mechanical induction coil connected to the TCR host senses the signal sent by the coding device. The performance of the TCR host is judged based on whether the light condition on the TCR host is consistent with the track circuit signal sent by the coding device below.

[0033] 2. When the EMU is undergoing advanced maintenance, the EMU will be erected and there will be a trench under the locomotive to facilitate the operators to inspect and replace parts. After replacing the induction coil, the TCR main engine performance will be tested. Figure 4 As shown, the traditional method is to use Velcro to hang the code rod under the machine induction coil. The code rod sends out a track circuit signal, and the machine induction coil connected to the TCR host senses the signal sent by the code generator. The performance of the TCR host is judged based on whether the light condition on the TCR host is consistent with the track circuit signal sent by the code generator below.

[0034] The train control vehicle-mounted TCR calibration device described in the utility model is an improvement based on the drawbacks of the above test methods. The TCR test device is used in conjunction with a mechanical coil hanger and a wireless code generator to achieve the detection of TCR performance. The details are as follows:

[0039] The front cover plate 3 and the second telescopic rod 2 , the upper cover plate 1 and the rear cover plate 4 , and the support plate 6 and the height adjustment plate 7 are all hingedly connected via hinges.

[0040] A groove is formed on the height adjustment plate 7 , and the support plate 6 can be embedded in the groove.

[0041] The rear cover plate 4 is provided with a scale, and the height can be adjusted to a suitable position by adjusting the height adjustment plate 7 according to the needs of on-site testing.

[0042] The test process of the train control vehicle-mounted TCR calibration device in actual application is as follows:

[0043] After fixing the encoder and the induction coil using the induction coil hanger, turn on the two encoders.

[0044] Connect the TCR test device to the test interface of the EMU track circuit reader on the train; turn on the TCR test device and pair it with the two code transmitters under the locomotive; after successful pairing, the TCR test device can remotely control the code transmitter to send codes and test the performance of the EMU track circuit reader.
