Problems solved by technology
Existing diesel engine control systems are all controlled by microcomputers with a single method, and the debugging of diesel engine control system lines is slow. If the locomotive microcomputer system or communication system fails, the diesel engine will lose control, the locomotive will lose its power source, and the locomotive will not be able to run, causing serious damage to the entire railway operation system. Security risks

The invention provides a locomotive diesel engine start-stop device and speed regulation control device. The locomotive diesel engine start-stop device and speed control device comprises a microcomputer control system, a standby starting device, a standby stopping device and a standby speed regulation device, wherein the standby starting device, the standby stopping device and the standby speed regulation device are directly connected to an diesel engine independently of the microcomputer control system; and the standby speed regulation device controls the speed of the diesel engine accordingto the gear of a driver controller. Through the locomotive diesel engine start-stop device and speed regulation control device, fault points of the whole set of diesel engine control system can be quickly checked in the locomotive debugging stage, an original diesel engine control system is no longer a simplex control system when the locomotive is running, a power source of the locomotive is guaranteed, and the running stability of the locomotive is improved.
Description
technical field [0001] The present invention generally relates to the field of diesel engine control, and more specifically relates to a diesel engine start-stop and speed regulation control device and method for a locomotive. Background technique [0002] The main transmission system of the DC diesel locomotive adopts the "AC-DC" electric transmission mode. The output end of the diesel engine drives a synchronous traction main generator to generate three-phase AC power, which is rectified by a silicon rectifier device and then sent to six fully parallel DC traction motors. Then the traction motor drives the wheel to rotate through the transmission gear. It can be seen that the locomotive diesel engine system is the power source of the electric system on the locomotive, and the sustainability of its start-stop and control system directly determines the performance of the entire locomotive. [0003] The start, stop and speed regulation of the existing locomotive diesel engin...
