Description

technical field [0001] The invention relates to the safety field of high-speed magnetic levitation trains, in particular to a test system for partitioned traction cut-off modules. Background technique [0002] When the train speed exceeds the maximum speed curve, the maximum speed curve monitoring function of the high-speed maglev operation control system will start, and the traction cut-off and the auxiliary braking function of the traction system will slow down the train; when the train speed is lower than the minimum speed curve, the high-speed maglev operation The minimum speed curve monitoring of the control system requires safe traction cut-off to ensure that the train can safely slide to the current auxiliary parking area by using the existing kinetic energy and potential energy; The system starts the traction cut-off to stop the train, thereby ensuring the safety of the system guidance. In other emergency situations, the operator can also send a traction cut-off com...

Problems solved by technology

[0004] In order to ensure the realization of the traction cut-off function and the safety and reliability of the system at the same time, the current partition traction cut-off modules are all implemented by a safety computer (two out of three or two out of two by two). It is more complicated, and the following problems generally exist:

[0005] Since the R&D and production of the partitioned traction cut-off module and the traction power supply system are generally carried out relatively independently (such as different units and different cities), the feasibility of debugging in the development stage is not ideal, and because the traction power supply system is expensive, the partitioned traction cut-off module It is not economical for R&D and production units to directly purchase the traction power supply system; in the development process of the partition traction cut-off module, its function cannot be guaranteed to be completely correct. If it is directly connected to the traction power supply system for testing, it may damage the expensive traction power supply system, resulting in a large degree of loss. To take a step back, even if the function of the partition traction cut-off module is correct after development, it still needs long-term operation and repeated tests to ensure its working stability, and the traction power supply system is a complex power consumption system. A high-power high-power system requires the cooperation of multiple people on site during the debugging process. If the traction power supply system is tested for a long time after the development is completed, a considerable amount of power consumption and accompanying labor costs will also be generated.

[0006] In addition, the real partitioned traction cut-off module cannot completely provide fault information for the traction power supply system, which is not conducive to testing the fail-safe characteristics of the measured object
