[0002] Currently, the ZPW2000 series track equipment is widely used in railways nationwide. However, its application in daily shift training and spare parts replenishment testing is not widespread. This makes it inconvenient for employees to operate and wire the equipment themselves, hindering their ability to handle emergency situations when ZPW2000 track circuit equipment malfunctions. It also prevents the need for thorough testing and confirmation of long-term stored spare parts before replacement, thus avoiding the need for secondary applications and track maintenance. Furthermore, most workshops and shifts lack training platforms.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] The following is a detailed description of the portable track circuit equipment training and testing platform of this utility model, with reference to the accompanying drawings.

[0021] Combined with appendix Figure 1-2 This invention will be described in detail below.

[0022] A portable testing and inspection platform for track circuit equipment includes a portable mobile platform 1 and a transmitter 2, a receiver 3, a surge protection simulation network box 4, a tuning unit 5, an analog signal acquisition device 6, and a monitoring and data display terminal 7 fixed on it. The transmitter 2 is connected to the tuning unit 5 via the surge protection simulation network box 4, and the tuning unit 5 is further connected to the track to simulate signal transmission in an actual working environment. The surge protection simulation network box 4 also has an analog signal acquisition device 6 connected in parallel for real-time monitoring and acquisition of the surge protection network's status parameters. The receiver 3 receives and processes signals by connecting to the RS chip of the transmitter 2. The monitoring and data display terminal 7 is responsible for acquiring the voltage and current data of the transmitter 2 and receiver 3 and displaying it in the form of voltage curves, allowing users to intuitively judge the operating status of the equipment.

[0023] This invention also includes a relay 8, which is connected to the RS chip of the transmitter 2 and is used to control the switching and transmission of signals, thereby increasing the flexibility and functionality of the test platform.

[0024] To support dual-track testing or improve test redundancy, this invention also designs two lightning protection simulation network boxes 4, each of which is connected to a tuning unit 5. The analog signal acquisition unit 6 is connected to both lightning protection simulation network boxes 4 simultaneously to achieve synchronous acquisition and monitoring of dual signals.

[0025] In the design of the portable mobile platform 1, this utility model adopts a combination structure of carrier 9, rollers 10 and push handle 11. The rollers 10 are set at the bottom of the carrier 9 to facilitate the movement and handling of the platform; the push handle 11 is set at the top of the carrier 9 to facilitate user operation and pushing, greatly improving the portability and practicality of the platform.

[0026] The specific implementation process of this utility model's portable track circuit equipment training and testing platform is as follows:

[0027] This utility model is applicable to the training and testing of ZPW2000 series track equipment. It can simulate setting fault points, track occupancy and restoration through the fault setting button switch.

[0028] The ZPW2000 series track equipment detection platform transmitter 2 uses a single transmitter 2, which does not require a train control center to provide encoding conditions, nor does it require a dual-machine hot standby redundancy mode. When a single transmitter 2 is connected via internal hooks, it meets the requirements of carrier frequency encoding and DC power supply. After providing a suitable power output level, transmitter 2 will send the detection code by default and can generate frequency shift signals to work normally.

[0029] Receiver 3 uses a single receiver 3. The external connection line includes the same working power supply, CAN address conditions, and carrier frequency encoding conditions as transmitter 2. There is no need to use a paired dual-machine parallel redundancy method. By meeting the main track signal input, track relay 8 output and receiver 3 alarm conditions through the connection conditions, receiver 3 can properly demodulate the track circuit frequency shift signal and activate track relay 8.

[0030] The attenuator is used to adjust the main track circuit, indicating transmission and reception faults, track occupancy, and the DC 24V power supply for transmission and reception, transmission output voltage, and reception GJ and XG test conditions.

[0031] The lightning protection simulation network box 4 is used for cable length compensation. The ordinary speed line is designed with six sections of 0.5, 0.5, 1, 2, 2, and 2 x 2 km. The sum of the cable length and the cable simulation network compensation length is 10 km, which can be adjusted as needed according to the site conditions.

[0032] The frequency of the outdoor transmitting and receiving tuning unit 5 must be consistent with the carrier frequency of this track circuit.

[0033] The power monitoring and acquisition panel is mainly used to collect the voltage and current of transmitter 2 and receiver 3, and to visually display the voltage curve of this section. It also includes an FBJ (Full-Flush Jumper) test; the testing platform, combined with on-site FBJ testing, checks the voltage variation range (within 24V±2V) to determine if there are any faults in the internal components of the module. Furthermore, a series voltage test is added; by connecting the testing platform casing to ground, a ground voltage test is performed, which can effectively rule out insulation problems in the internal components of transmitter 2 and receiver 3.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
