A modular test system for subdivision turnouts

Abstract

The present invention provides a modular testing system for turnouts in different regions, including a turnout power supply traction simulation unit, a system host, a switch position and locking sensor simulation unit, and a communication unit; wherein: the turnout power supply traction simulation unit is used to simulate the power supply of the turnout system The system host controls the switch position and the lock sensor simulation unit to simulate the switch position of the switch system and the locking information at this position, and controls the power supply traction simulation unit of the switch to provide the cut-off state of the measured object for The measured object is collected; the communication unit is used for communication between the measured object and the system host. The invention considers the complexity and completeness of the test, and through associating the test system with the equipment to be tested, the test function of the divisional switch module is completely realized.

Description

technical field [0001] The invention relates to the safety field of high-speed magnetic levitation trains, in particular to a test system for sub-regional turnout modules. Background technique [0002] The high-speed maglev turnout is a track switching facility set up to enable high-speed maglev trains to run on different tracks. In order to ensure the operation of the maglev train, the operation control system must ensure that the turnouts passing by the route are in the correct position and have been locked safely, so as to ensure that the functions of switch movement and protection are finally implemented through the divisional switch module DSM. [0003] In order to ensure the functional realization of the divisional turnout and the safety and reliability of the system at the same time, the divisional turnout module is realized 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: [0004] ...

Problems solved by technology

[0003] In order to ensure the functional realization of the divisional turnout and the safety and reliability of the system at the same time, the divisional turnout module is realized 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:

[0004] Since the R&D and production of the divisional turnout module DSM and the turnout control 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 high-speed magnetic levitation turnout system is very complex, bulky and The price is expensive, and it is not economical for the R&D and production units of the divisional turnout module to directly purchase the turnout system; in the development process of the divisional turnout module, its function cannot be guaranteed to be completely correct. If it is directly connected to the turnout system for testing, it may be damaged and expensive turnout system, which leads to a large degree of loss. Taking a step back, even if the function of the divisional turnout module is correct after the development is completed, it still needs long-term operation and repeated tests to ensure the stability of its work, and the turnout system is complex and energy-consuming. The high-power system with high power requires the cooperation of multiple people on site during the debugging process. If the turnout system is tested for a long time after the development is completed, a considerable degree of power consumption and accompanying labor costs will also be generated.

[0005] In addition, the real partitioned turnout module cannot completely provide fault information for the turnout system, which is not conducive to testing the fail-safe characteristics of the measured object
