[0028] Among them, the motor simulator is a device used to simulate the real cabinet environment, and is usually used to test and verify the performance and stability under different working conditions. Through the motor simulator, different environmental parameters such as temperature, humidity, voltage, etc. can be simulated to conduct comprehensive performance testing and reliability evaluation. This helps to ensure that the equipment can operate normally in various working environments and improve the quality and reliability of the motor.

[0029] In this embodiment, refer to Figure 3 As shown, the Canoe host computer includes a control information module, and the control information module includes at least one of a motor angle module, a direct axis current module, a quadrature axis current module, and a three-phase current module. For example, the control information module of the motor simulator test includes a motor angle module and a direct axis current module; or includes a motor angle module, a direct axis current module, and a quadrature axis current module, etc. Of course, what is said here is only one way that can be implemented. The control information module in the specific motor simulator includes but is not limited to the modules mentioned above.

[0030] Furthermore, the motor simulator is a load simulation device for the motor, which responds to various control information of the motor controller, and then feeds back relevant working information to the Canoe host computer after the motor is running to verify whether the function of the motor controller is normal.

[0031] In this embodiment, the working information module includes at least one of a torque working module, a speed working module, a power working module and a temperature working module. For example, the working information module includes a torque working module and a speed working module; or includes a torque working module, a speed working module, a power working module, etc. What is described here is only one possible implementation method, and the specific working information module includes but is not limited to the modules mentioned above.

[0032] Furthermore, the Canoe host computer is a computer or device in the industrial control system that is responsible for managing, monitoring and controlling the entire system. The Canoe host computer receives the working information collected by the motor simulator and processes and controls it according to the preset logic. The Canoe host computer usually has higher computing power and human-computer interaction interface, which can realize remote monitoring, parameter adjustment, data recording and analysis of the entire industrial control system.

[0033] Reference Figure 2As shown, the Canoe host computer is connected to the motor controller through communication, the motor controller is connected to the input end of the motor simulator through a wire, and the output end of the motor simulator is connected to the motor controller through a wire; the output end of the motor simulator is also connected to the Canoe host computer through communication. In addition, the working information of the motor tested by the motor simulator can also be directly stored in the motor controller, the working information and control information in the motor controller can be read through the display screen, and the test results can be displayed by a specific algorithm analysis, so as to more intuitively understand the working status of the motor.

[0034] The motor testing system also includes a display screen, which includes a control information display area, a working information display area and a fault information display area. The display screen is connected to the Canoe host computer and the motor controller through wires, and then the data in the control information module and the working information module are displayed in the relevant display area of ​​the display screen, and the test results are displayed through specific algorithm analysis; and the fault information stored in the motor controller itself during operation is displayed in the fault information display area, so as to more intuitively understand the working status of the motor.

[0035] The motor controller includes a UDS diagnostic module and a drive module. The UDS diagnostic module is used to collect fault information of the motor controller and feed it back to the display screen during detection for the next step of operation. Of course, the UDS diagnostic module can also be updated through the human-machine interface. The drive module is used to transmit the control information in the control information module to the motor simulator.

[0036] In the motor test system, the UDS diagnostic module mainly collects information including motor overcurrent, overvoltage, overspeed and incomplete data.

[0037] UDS automatic testing is a diagnostic service protocol used for communication between automotive electronic control units. UDS automatic testing usually refers to automated testing of the diagnostic system on the vehicle to verify and ensure the functionality and performance of the diagnostic system.

For example, regarding the torque diagnostic module, the operator can click on the torque correction module before performing a diagnosis. The operator can determine whether to perform a motor test by observing the swing of the simulation pointer or whether the data reading is normal.

[0040] Of course, in the correction module, you can also set up a one-button simultaneous detection of whether multiple diagnostic modules are working properly, avoiding separate verification of each diagnostic module, which is faster and more convenient.
