Description

Technical Field

[0001] This utility model relates to the field of railway signaling equipment, specifically a touch-screen LEU message reading device based on GSM-R railway dedicated network data transmission. Background Technology

[0002] In recent years, high-speed railways have made remarkable progress, and the higher train speeds have placed higher demands on the accuracy and reliability of messaging equipment.

[0003] Existing message reading devices mostly use probes inserted into the LEU test port slots inside the LEU cabinet. When reading messages, operators need to manually hold down the probes while simultaneously operating the device's buttons to read and review the LEU messages. After reading the LEU messages, the operator returns to the office area to export the messages from the device to the message management computer for data analysts to analyze for anomalies. Because LEU message reading operations are frequent and require reading a large number of messages each time, existing message reading devices often have the following problems and defects:

[0004] 1. When reading LEU messages, the operator needs to manually keep the probe in contact with the metal contact spring in the LEU test port slot to read the data. The operator's hand may shake, which often causes poor contact with the metal contact spring, resulting in data reading failure and affecting the efficiency of the operation.

[0005] 2. When reading LEU messages, if the operator presses the probe tip against the spring in the LEU test port slot with heavy force for a long time and at high frequency, it can easily cause the spring to deform and loosen, or the plastic of the test port to be punctured by the probe tip, resulting in damage to the test port.

[0006] 3. When reading LEU messages, the operator needs to hold the message reading device with one hand and press various buttons on the device (such as read, page up / down, return, confirm, etc.) while pressing the probe. This two-handed operation causes great inconvenience to operators with heavy workloads.

[0007] 4. When reading LEU messages, because the LEU message reading operation is frequent and the number of messages read each time is large, it is necessary to press the buttons of the LEU message reading device frequently. Over time, this will cause the buttons to be damaged, which will lead to damage to the entire device.

[0008] 5. After completing the LEU message reading, the operator returns to the office area and needs to export the message data read from the message reading device to the message management computer terminal for data analysts to analyze the message. This message transmission method is inconvenient for the operator in terms of both convenience and timeliness. Utility Model Content

[0009] To address the aforementioned issues, this invention provides a touch-screen LEU message reading device based on GSM-R railway dedicated network data transmission, which is convenient for operators to use and improves the success rate of LEU message reading.

[0010] The technical solution adopted by this utility model to solve its technical problem is as follows: a touch-sensitive LEU message reading device based on GSM-R railway dedicated network data transmission, including an LEU device and an LEU message reading device. The LEU device is provided with a test port slot, and the LEU message reading device is provided with a plug. The plug is provided with a protrusion that mates with the test port slot. The protrusion is provided with a protrusion, and the test port slot is provided with a spring piece that mates with the protrusion to fix the protrusion.

[0011] Furthermore, the protrusion is either a gently sloping circular protrusion or a spherical protrusion. The height of the protrusion is 1 mm.

[0012] Furthermore, the plug is connected to the LEU message reading device via a wire, the other end of which is provided with a pin. The LEU message reading device is provided with a pin interface that mates with the pin. The pin-type design facilitates insertion and removal, provides greater flexibility during use, and the pin interface has good oxidation and moisture resistance, reducing signal instability caused by contact and providing a better LEU message reading success rate.

[0013] Furthermore, the LEU message reading device is equipped with a touch screen display, replacing button operation with touch screen operation, eliminating the need to switch between various buttons, which improves work efficiency and reduces the probability of physical damage to the equipment.

[0014] Furthermore, the LEU message reading device is equipped with a SIM card slot for the GSM-R railway dedicated network (also supporting ordinary commercial 3G / 4G / 5G communication cards), which transmits the acquired message data to the back-end management terminal in real time via wireless data transmission for analysis by analysts. This function greatly shortens the data transmission time, saving valuable time for emergency fault repair. It improves work efficiency and provides convenience for operations.

[0015] Furthermore, the LEU message reading device is also equipped with a control switch.

[0016] The beneficial effects of this utility model are as follows: This design transforms the probe-type plug of the LEU message reading device test meter into a insert-type plug that fits snugly into the test port slot, improving the success rate of message data reading, enhancing the convenience of operation for operators, and reducing the probability of LEU test port damage. The touchscreen operation mode facilitates quick reading, page turning, returning, and closing operations, improving work efficiency under heavy workloads. The mobile data transmission function significantly shortens data transmission time, saving valuable time for emergency repairs. Overall, this design improves work efficiency and provides greater convenience for operations. Attached Figure Description
