Embodiment Construction

[0019] See attached Figure 1~3 , the self-detection circuit of the diesel locomotive controller in this embodiment, after the PWM channel of the controller ADLC is connected to the FI channel, it is connected to the 110V power supply through a resistor, after the DO channel is connected to the DI channel, it is connected to the 110V power supply through a resistor, and the AO channel is connected to the 110V power supply through a resistor. The AI ​​channel is directly interconnected with wires, the CAN bus channel is directly connected with the CAN channel of the PC (using the USB extended CAN channel), and the RS485 channel is directly connected with the RS485 channel of the PC.

[0020] The basic principle of the self-inspection method of the diesel locomotive controller in this embodiment is to use the existing electrical channels of the ADLC of the diesel locomotive controller to perform self-inspection through interconnection. The PWM channel and the FI channel are inte...

Abstract

The invention relates to a circuit and a method for self-detection of an ADLC (advanced diesel locomotive controller). A PWM (pulse-width modulation) channel of the ADLC is interconnected with an FI (filter input) channel, a DO (digital output) channel is interconnected with a DI (digital input) channel, an AO (analog output) channel is interconnected with an AI (analog input) channel, a CAN (controller area network) bus channel of the ADLC is connected with a CAN bus channel on an upper computer PC (personal computer), an RS485 channel of the ADLC is connected with an RS485 channel of the PC, the ADLC sets the output of the PWM channel, the DO channel and the AO channel according to the CAN messages sent by the PC, meanwhile, the ADLC sends the FI, DI and AI detection results to the PC through the CAN bus, the PC sends a life signal to the ADLC through the RS485 channel, the ADLC receives the signal and then returns the signal to the PC through the RS485 channel, and the PC displays and compares the sent and received life signal. The method has the advantages that the original manual detection mode is replaced, the detection efficiency and detection accuracy are greatly improved, and a reliable testing method is provided for the fault diagnosis and maintenance of the controller.

Description

technical field [0001] The invention relates to a self-detection circuit and method for a controller of a diesel locomotive, belonging to the technical field of railway locomotives. Background technique [0002] The diesel locomotive controller is the main control system of the diesel locomotive, which is mainly responsible for the speed regulation control of the diesel locomotive diesel engine, locomotive load control, operating parameter detection, control and other tasks. The multiple control boards in the chassis work in coordination at the same time to realize the control function. Each control board has frequency input, switch input, analog input, excitation output, switch output, analog output, and RS485 channel. In order to ensure the quality and reliability of the controller, it must be functionally tested before leaving the factory. In the existing technology, in order to perform functional testing on all channels, it is necessary to build a control board test be...
