[0002] The Shanghai demonstration line of the high-speed maglev train consists of four maglev trains, each of which includes two lead cars and several mid-cars. Lead car A includes two onboard radio control units (MRCU) and two onboard radio transceivers (MST). Lead car B includes two onboard radio transceivers (MST), both of which are train operation control system (VOCS) equipment.

[0003] The Train Operation Control System (VOCS) and the Train Control System (VCS) have a physical interface, including the connection between the Positioning Processing Unit (ORTPR) and the Onboard Radio Control Unit (MRCU), and the connection between the Onboard Radio Control Unit (MRCU) and the Onboard Radio Transceiver (MST). These two connection links transmit train positioning data and other radio data to the ground base station, respectively.

[0004] Because lead car B is far from lead car A, the two onboard radio transceivers (MSTs) and the train positioning sensor on that side of lead car B need to be connected to lead car A via transition cables. All equipment on the lead car and above is connected via adapters. In the event of a fault, problems often arise such as excessive distance making detection inconvenient, or insufficient space making fault diagnosis difficult.

[0005] If the location of the faulty cable cannot be detected smoothly and quickly, it will affect train positioning, communication, and control, posing a great risk to train operation. Utility Model Content

[0042] like Figure 1 and Figure 2 As shown in the figure, this embodiment discloses a high-speed maglev vehicle-mounted cable testing auxiliary device. The high-speed maglev vehicle-mounted cable testing auxiliary device includes a first testing module 1 and a second testing module 2. The first testing module 1 includes a connector 11, a first cable 12 and a first interface panel 13.

The second testing module 2 includes an interface 21, a second cable 22 and a second interface panel 23. The two ends of the second cable 22 are respectively connected to the interface 21 and the second interface panel 23. The interface 21 is used to connect the cable port. The first interface panel 13 and the second interface panel 23 are both used for short-circuit testing and measurement. The first interface panel 13 and the second interface panel 23 correspond to each other and are used to detect the cable resistance between the vehicle-mounted motion control equipment.

[0043] When using the high-speed maglev vehicle-mounted cable testing auxiliary device, the first test module 1 is connected to the MST signal cable via connector 11, and the first interface panel 13 is used for testing and measurement; the second test module 2 is connected to the cable port via interface 21, and the second interface panel 23 is used for testing and measurement. The first interface panel 13 and the second interface panel 23 cooperate with each other to detect the cable resistance between the vehicle-mounted control equipment. The device cables are tested by short-circuiting, avoiding the complex method of laying long-distance test cables required for testing through-cables, greatly simplifying the preparation and verification work for cable testing, and significantly improving the efficiency and accuracy of cable testing. At the same time, considering the maximum compatibility and convenience of the product, both the first test module 1 and the second test module 2 are modularly designed. Using a modular design, the equipment interfaces are brought out, providing a flexible and reliable testing method for testing work in limited maintenance spaces, greatly reducing the physical exertion of maintenance personnel in low-maintenance space conditions, and improving the convenience of testing. The high-speed maglev on-board cable testing auxiliary device of this embodiment can be used for testing the signal cables of the on-board operation control system of all trains on the Shanghai line. In later use, functions such as digital display and buzzer can be gradually added to provide ample expandability and continuous upgrades to the testing auxiliary device. This will provide a more complete and convenient testing method for maintenance and testing work, significantly saving personnel costs and improving equipment availability. The high-speed maglev on-board cable testing auxiliary device can be made of engineering plastics.

[0044] The dimensions of the first test module 1 are 385*145*140 (length*width*height mm), and the dimensions of the second test module 2 are 200*145*140 (length*width*height mm). Connector 11 is a circular aviation connector, and the first test module 1 is connected to the MST signal cable through the circular aviation connector.

[0045] In this embodiment, the first cable 12 has 26 cores, the connector 11 is a 26-pin circular connector, and the first interface panel 13 is an AS interface panel used for testing and measurement. The second cable 22 has 25 cores, the interface 21 is a 25-pin D-type connector used to connect to the MRCU_W9XX cable port, and the second interface panel 23 is a 1-25 numbered interface panel used for testing and measurement. The connector pin numbers in the first test module 1 and the second test module 2 correspond to the interface numbers of their respective panels.

[0046] In this embodiment, the high-speed maglev vehicle-mounted cable testing auxiliary device is used by first connecting the first test module 1 to the MST communication cable connector and the second test module 2 to the MRCU_W9XX cable. Then, using a multimeter set to the ohm range, perform combined short-circuit measurements according to the table.

At the same time, short-circuit pins D and F on the first interface panel 13 of the first test module 1 with a multimeter to perform a through resistance test. A value not exceeding 20Ω is considered normal.

[0047] The first interface panel 13 includes a first test box 131 and a plurality of first terminals 132. A first cable 12 extends into the first test box 131 and connects to the plurality of first terminals 132. All the first terminals 132 protrude from the same side of the first test box 131. By installing all the first terminals 132 inside the first test box 131 and exposing them on the same side, the first interface panel 13 is used for external connection via the first terminals 132, making it very convenient to use. The side of the first test box 131 has letter markings corresponding to the plurality of first terminals 132. The number of first terminals 132 is 16.

[0048] The second interface panel 23 includes a second test box 231 and a plurality of second terminals 232. A second cable 22 extends into the second test box 231 and connects to the plurality of second terminals 232. All the second terminals 232 protrude from the same side of the second test box 231. By installing all the second terminals 232 inside the second test box 231 and exposing them on the same side, the first interface panel 13 is used for external connection via the second terminals 232, making it very convenient to use. The side of the second test box 231 has numerical markings corresponding to the plurality of second terminals 232. The number of second terminals 232 is 25.

[0049] The first test module 1 also includes a first connector 14, which is sleeved on the first cable 12 and connected to the first interface panel 13. The first connector 14 is used to seal the first cable 12 to the first interface panel 13, providing high connection stability and ease of use.

[0050] The second test module 2 also includes a second connector 24, which is fitted onto the second cable 22 and connected to the second interface panel 23.

[0051] The high-speed maglev vehicle-mounted cable testing auxiliary device also includes an adapter 3, which is detachably connected to the connector 11 or the interface 21. The first test module 1 and the second test module 2 are used in combination to detect the cable resistance between vehicle-mounted motion control equipment.

This enables the high-speed maglev vehicle-mounted cable testing auxiliary device to be compatible with existing vehicle-mounted equipment 24V / 5V voltages, thus having a wide range of applications.

[0052] The adapter 3 includes a third cable 31, a first adapter 32, and a second adapter 33.

The first adapter 32 or the second adapter 33 is detachably connected to the connector 11 or the interface 21. One of the first adapter 32 and the second adapter 33 can be connected to the connector 11 or the interface 21, while the other is used to connect other types of cables.

[0053] In this embodiment, the high-speed maglev vehicle-mounted cable testing auxiliary device is mainly used to support the stable operation of the Shanghai line and improve the system maintenance rate. It enables rapid location of faults in communication cables and cross-professional interface cables of the Shanghai Maglev Demonstration Line's vehicle-mounted operation control system, improves maintenance efficiency, and effectively ensures the long-term continuous operation of the Shanghai Maglev Demonstration Line.

[0054] (1) To maximize the compatibility and convenience of the product, a modular design is used to bring out the equipment interface, which can provide a flexible and reliable testing method for testing work in a limited maintenance space, greatly reduce the physical exertion of maintenance personnel in low maintenance space conditions, and improve the convenience of testing.

[0055] (2) By using the short-circuit method to test the equipment cables, the complex method of laying long-distance test cables is avoided, which greatly simplifies the preparation and verification work for cable testing and significantly improves the efficiency and accuracy of cable testing.

[0056] (3) It can be used for the detection of signal cables of the on-board operation control system of all trains on the Shanghai line. In the later use, digital display, buzzer and other functions can be gradually added to provide sufficient expandability.

[0057] This effectively avoids communication disruptions between equipment due to signal cable faults on trains, effectively solves problems such as difficulty in locating and judging onboard cable faults and difficulty in testing due to insufficient maintenance space in cabinets, effectively reduces the time and physical labor costs of fault diagnosis, and improves the effectiveness of fault diagnosis and testing methods.
