Description

Technical Field

[0001] This utility model belongs to the technical field of rail transit vehicle equipment, specifically relating to an ATP software upgrade and version verification system for high-speed trains. Background Technology

[0002] In the rail transit sector, the Automatic Train Protection (ATP) system, as a core onboard device ensuring the safe operation of high-speed trains, directly impacts train operation safety and efficiency due to the stability and timeliness of its software functions. Currently, domestic high-speed trains widely utilize various ATP models, including the 300S, 300H, 300T, 200H, and 200C. These systems require at least one software upgrade annually based on operational needs and technological advancements. However, existing upgrade methods have significant limitations: firstly, a single train's ATP software upgrade typically takes over 3 hours, and with the continuous increase in the number of high-speed trains deployed, the workload for upgrades rises dramatically; secondly, onboard equipment workshops generally face a low personnel-to-train ratio, making staff organization and allocation difficult, hindering upgrade efficiency and failing to meet the maintenance needs of large-scale train fleets. Meanwhile, traditional upgrade equipment lacks integrated design, relies on external power supplies, and has poor interface compatibility, making it difficult to meet the upgrade needs of multiple ATP (Automatic Train Protection) equipment models and achieve simultaneous upgrades of multiple boards. Furthermore, software version verification after upgrades largely depends on manual operation, lacking standardized recording and closed-loop control mechanisms, which can easily lead to version inconsistencies and a lack of traceability in the upgrade process, posing potential safety hazards to train operation. Therefore, developing a portable, efficient, multi-model compatible ATP software upgrade and version verification system with closed-loop verification capabilities has become an urgent technical problem to be solved in the field of rail transit onboard equipment operation and maintenance. Summary of the Invention

Detailed Implementation

[0018] The following description, in conjunction with the accompanying drawings of specific embodiments of the present invention, will provide a clear and complete illustration of exemplary solutions. Unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art.

[0019] This utility model discloses an ATP (Automatic Train Protection) software upgrade and version verification system for high-speed trains, including a battery power supply and an ATP board upgrade chassis connected to the battery power supply. The battery power supply includes battery units, a power management circuit, a control unit, and a charging interface. The power management circuit is connected to the battery units and provides DC 110V and DC 24V power outputs. The control unit includes a touch screen and a relay switching circuit. The touch screen receives the ATP equipment model command selected by the user. The relay switching circuit responds to the command and controls the DC 110V power interface to output the appropriate power to the corresponding ATP equipment cabinet power supply interface. For example, when powering a 300S ATP, it may be necessary to power the ALA unit first and then the JRU; while when powering a 200H ATP, the power supply sequence and the units involved (VC, DRU, STM, etc.) are completely different. The charging interface is used to connect to an external AC power supply (AC 220V) to charge the battery units and power external equipment, which refers to the ATP cabinet or ATP board upgrade chassis that needs to be upgraded, to ensure operational continuity. The battery power supply utilizes mature battery cells and power management circuits, featuring battery protection functions including overcharge, over-discharge, short circuit, overload current, and temperature protection. It uses an AC220V charging socket with a charging interface located on the back of the power supply and equipped with a charging switching circuit, allowing simultaneous power supply to external devices and battery charging during the charging process.

[0020] The battery power supply also includes a casing, a power status indicator light, a work light, and a power display unit. The casing is made of aluminum alloy and has a portable rubber handle for easy carrying. The power status indicator light indicates the working status of the main power supply, DC110V output, and DC24V output. The work light provides a working light source for construction workers. The power display unit displays information such as battery voltage, remaining power, charging status, and output power.

[0021] The battery cell performance of the power supply shall meet the following requirements: battery capacity not less than 0.3 kWh; rated output power not less than 400 watts, and continuous working time not less than 1 hour under 400 watt load and not less than 2 hours under 200 watt load; AC220V charging, charging time not more than 3 hours; battery cycle life greater than 4000 cycles and capacity retention not less than 70%; overall weight not more than 5 kg, and dimensions not more than 250 mm (length) × 160 mm (width) × 150 mm (height).

[0022] The control unit is configured to: when a user selects a specific ATP model via the touchscreen, control the relay switching circuit to control the on / off switching of multiple DC110V power supplies output to the power adapter according to the preset logic corresponding to that model, so as to achieve time-sharing independent power supply to different functional units in the target ATP device; typical application scenario: upgrading unit by unit, which is the most common and reliable mode, avoiding the surge current impact on the battery power supply caused by multiple units being powered on at the same time; the software upgrade process is clear and faults are easy to isolate.

[0023] The system also includes various power adapter cables for connecting the DC 110V battery power interface to the power interfaces of different ATP devices, including the 300S, 300H, 300T, 200H, and 200C models. Details are as follows: ①For example Figure 1 and Figure 2 As shown, the DC110V power interface of the battery power supply is connected to the J100 power interface of the 300S ATP via a 300S power adapter cable. The relay switching circuit controls the power on and off of the ATP, JRU, DMI1, and DMI2 power interfaces via software. The ATP power interface provides slave power to the ALA unit, BTM unit, and GSM-R unit, the JRU power interface provides direct power to the JRU unit, and the DMI1 and DMI2 power interfaces together provide redundant power to the DMI unit. Independent power supply control for each unit is achieved by combining the circuit breaker of the 300S ATP circuit breaker module.

[0024] ②For example Figure 5 and Figure 6As shown, the DC110V power interface of the battery power supply is connected to the CN2 power interface of the 300H ATP via a 300H power adapter cable. The relay switching circuit controls the power-on and power-off of the DMI, VC1, VC2, MSU, BTM and fan power units via software. Among them, the VC1 and VC2 power interfaces provide main and backup power to the VC unit, and also provide slave power to the RTM unit and GSM-R unit. The MSU power interface provides direct power to the MSU unit, the BTM power interface provides direct power to the BTM unit, and the DMI power interface provides direct power to the DMI unit.

[0025] ③ For example Figure 3 and Figure 4 As shown, the DC110V power interface of the battery power supply is connected to the CN2 power interface of the 200H ATP via a 200H power adapter cable. The relay switching circuit controls the power on and off of the DMI, VC, DRU, STM, BTM and fan power supplies via software. The DMI power interface provides direct power to the DMI unit, the VC power interface provides direct power to the VC unit, the DRU power interface provides direct power to the DRU unit, the STM power interface provides direct power to the STM unit, and the BTM power interface provides direct power to the BTM unit.

[0026] ④ For example Figure 7 and Figure 8 As shown, the DC110V power interface of the battery power supply is connected to the P1 power interface of the 200C ATP via a 200C power adapter cable. The relay switching circuit controls the power-on and power-off of EVC-A, EVC-B, and EVC-C via software. Among them, EVC-A, EVC-B, and EVC-C units are triple redundant power supply modules for the EVC unit, providing redundant power supply to the EVC unit. The EVC unit contains CCTE module, CFSK module, CODOU module, MTORE module, and CBCH configuration data. The BTM unit and DMI unit are both subordinate functional modules of the EVC unit, obtaining power through the internal power supply circuit of the EVC unit.

[0027] ⑤ For example Figure 9As shown, the DC110V power interface of the battery power supply is connected to the X7 power interface of the ATPCU, C2CU, TSG, SDP, STU-VN, and STU-VV of the 300T ATP through a 300T power adapter cable, supplying power to the ATPCU, C2CU, TSG, SDP, STU-VN, and STU-VV units; it is connected to the BTM power interface through a 300T BTM power adapter cable (including the original BTM and the self-developed BTM), and connected to the GSM-R power interface through a 300T GSM-R power adapter cable. The BTM power interface directly supplies power to the BTM unit, and the GSM-R power interface directly supplies power to the GSM-R unit (since there is no available power interface for the DMI, the system does not support software upgrades for the DMI unit).

[0028] The general process for upgrading the ATP (Automatic Train Protection) system software on high-speed trains is as follows: 1. System preparation and connection: Connect the DC110V power output of the battery power supply to the power interface of the target ATP cabinet through the corresponding model of dedicated adapter cable; 2. Intelligent power supply start-up: Select the ATP model on the system touch screen. According to the preset logic, the system will sequentially connect the DC110V power supply to the designated functional units (such as VCU, BTM, DMI, etc.) in the cabinet through relays in a time-sharing manner. 3. Perform software upgrade: After the target unit is powered on and stabilized, connect its maintenance interface through the host computer and dedicated data cable, run the upgrade tool, and complete the erasure, burning, and verification of the unit's software / data.

[0029] 4. Iteration and Completion: Repeat steps 2-3 in the upgrade order to complete the operation of all units in the cabinet that need to be upgraded. Finally, power off the machine to complete the overall upgrade.

[0030] The system provides two types of ATP board upgrade chassis: the first type upgrade chassis (such as...) Figure 10 (as shown) and second-class upgrade chassis (such as Figure 11 (As shown).

[0031] The first type of upgrade chassis is equipped with power supply interfaces for the ALM, EVC, TMM, and RIM (including the proprietary RIM) boards of the 300S ATP, and can power four boards simultaneously. Specifically, the 300S board upgrade chassis can simultaneously power four modules: EVC, ALM, TMM, and RIM (including the proprietary RIM), to meet the needs of board program and configuration upgrades. The battery power supply provides power to the DC24V input power interface of the 300S board upgrade chassis. After pressing the power button, the power indicator light will illuminate, and power will be supplied to the EVC and other modules through the chassis base plate.

[0032] The second type of upgrade chassis is equipped with power supply interfaces for the VC unit OPE and FSC modules of the 200H ATP, the VC unit EOP module of the 300H ATP, and the EVC unit CCTE module of the 200C ATP, enabling simultaneous power supply to four boards. Specifically, the 200H / 200C / 300H board upgrade chassis can perform program upgrades and version verifications for the 200H VC unit FSC and OPE modules, the 200C CCTE module, and the 300H EOP module. After the battery power supply powers the 200H / 200C / 300H board upgrade chassis, it simultaneously powers all four modules through the chassis base plate.

[0033] The ATP board upgrade chassis is powered by a DC 24V battery output. The chassis features an aluminum alloy shell and a portable rubber handle. Figure 12 As shown, it is easy to carry, weighs no more than 5 kg, and has dimensions no greater than 250 mm (length) * 160 mm (width) * 150 mm (depth). Both the battery power supply and ATP board upgrade chassis are equipped with storage boxes and a high-quality backpack.

[0034] The second type of upgrade chassis also integrates a version verification interface, specifically including: The 200H VC FSC version verification interface is used to extract the RS422 interface signal used by the FSC module to communicate with the DRU unit. The RS422 communication data is read and parsed from this interface to obtain the software version number of the upgraded FSC module. The 200H VC OPE version verification interface is used to obtain the software version number of the upgraded OPE module through RS422 communication data parsing.

[0035] The EOP module of the 300H ATP is connected to the PCR module of the 300H ATP via the VME bus on the chassis base plate, and the PCR module records the version information of the EOP module.

[0036] The process for upgrading software using an ATP board upgrade chassis is as follows: 1. Chassis Power Supply: Connect the DC24V power output from the battery power supply to the power input interface of the ATP board upgrade chassis to provide power to all board slots in the chassis simultaneously.

[0037] 2. Board Installation: Correctly insert the ATP board to be upgraded (such as the EVC or ALM board for the 300S) into the corresponding dedicated slot in the chassis; 3. Sequential connection and upgrade: The operator uses a dedicated data cable to connect to the independent upgrade interface of each board in sequence, and performs software burning, verification and version reading operations on each board through the host computer software.

[0038] 4. Completion and Removal: After all boards have been upgraded and verified to be correct, disconnect the power, remove the boards from the chassis, and complete the offline upgrade process.

[0039] The system also includes a version verification module, which is used to obtain and verify the upgraded software version after the upgrade is completed. ① 300S ATP: The 300S version verification only processes the three modules of the ALA unit: EVC, ALM, and TMM. Other modules are read by the manufacturer's software. The 300S data download cable is inserted into the RS232 interface of the EVC, ALM, and TMM modules. The CRC value of the program file is read via commands and compared with the CRC value in the program file.

[0040] ②200H ATP: If the software upgrade is performed through the 200H cabinet, the upgraded version number is obtained by reading the DRU unit PC card data after powering on the 200H cabinet; if the software upgrade is performed through the ATP board upgrade chassis, the upgraded FSC board version number is obtained by reading and parsing the RS422 communication data of the 200H VC FSC version verification interface, and the upgraded OPE board version number is obtained by reading and parsing the RS422 communication data of the 200H VC OPE version verification interface.

[0041] ③300H type ATP: Obtain the upgraded version number of the OPE module by reading the PC card data of the VC unit PCR module.

[0042] ④200C type ATP: Obtain the upgraded version number by downloading the CCTE module SAM data.

[0043] ⑤ 300T ATP: Obtain the upgraded version number by downloading the log data of each module.
