Innovation Solution
A magnetic levitation test system comprising a central control unit, vehicle on-board controller test-bed, electromagnet controller test platform, and electromagnet test-bed, which allows for joint testing of the vehicle on-board controller, electromagnet controller, and electromagnet by simulating operational states and transmitting control commands to perform function verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional technology is used, then the system structure remains simple, but the vehicle on-board controller, electromagnet controller, and electromagnet cannot be tested
Solution Approach 1:
The test system is divided into four independent modules: central control unit, vehicle on-board controller test-bed, electromagnet controller test platform, and electromagnet test-bed. Each module can be independently configured and tested, enabling comprehensive testing of individual components while maintaining overall system integration. This segmentation resolves the contradiction by providing testing capability through modular architecture rather than a monolithic system.
Solution Approach 2:
The central control unit acts as an intermediary that coordinates communication between all test modules. It transmits control commands to the vehicle on-board controller test-bed, which then communicates with the electromagnet controller test platform, and finally to the electromagnet test-bed. This intermediary structure enables complex testing functionality while maintaining manageable system organization.
2Measurement precision
If the test system is not established, then the system complexity remains low, but the performance verification of controllers and electromagnets cannot be performed
Solution Approach 1:
The test system employs dynamic signal transmission and control where the central control unit sends real-time control commands through the hierarchical test beds. The system dynamically adjusts test parameters and monitors performance metrics, enabling precise performance verification through active control rather than static measurement arrangements.
3Adaptability or versatility
If hierarchical test beds are implemented, then joint testing capability is achieved, but the system complexity increases
Solution Approach 1:
The hierarchical test bed structure serves multiple functions: the central control unit coordinates all tests, the vehicle on-board controller test-bed interfaces with multiple controllers, the electromagnet controller test platform tests different electromagnet controllers, and the electromagnet test-bed verifies electromagnet performance. This multi-functional design enables joint testing of various component combinations without requiring separate dedicated test systems for each scenario.

AI summary
A magnetic levitation test system and an electromagnet test method. A vehicle-mounted controller (1024), an electromagnet controller, and an electromagnet are subjected to joint test by means of the magnetic levitation test system integrated with a vehicle-mounted controller test bed (102), an electromagnet controller test bed (104), and an electromagnet test bed (106). The running condition of a train can be simulated, and the vehicle-mounted controller (1024), the electromagnet controller, and the electromagnet are subjected to joint test under the simulated running condition of the train. Therefore, the vehicle-mounted controller (1024), the electromagnet controller, and the electromagnet are subjected to function verification, thereby reducing the fault rate when the vehicle-mounted controller (1024), the electromagnet controller, and the electromagnet are used at the same time.
