Problems solved by technology
However, the cost of building an electropneumatic brake system test bench is very high, and generally only suppliers have this condition
Moreover, this kind of test bench of the supplier is mainly used for production testing, and the joint debugging test written by the vehicle manufacturer's combined screen program can only be carried out in the blank, which not only affects the normal production of the supplier, but also the software development efficiency is extremely low, adding high development cost

The invention provides a microcomputer screen-combining simulation debugging method for a locomotive master control system and an electric pneumatic breaking system. According to the method, central processing module simulation software of the electric pneumatic breaking system is mounted in a simulation computer; a certain number of electrical control unit simulation data analog schemes under various working states or failure states of the electric pneumatic breaking system are set; electrical control unit simulation data signals of all the analog schemes are sent to the simulation computer through a man-machine conversation input interface, the central processing module simulation software packages the data in real time and sends the data to a locomotive master control system microcomputer and a microcomputer display screen through communication conversion equipment; the data sent by the locomotive master control system to the electric pneumatic breaking system are observed through a real-time monitoring display window, and tested program software is adjusted according to an observed check result. With the adoption of the method, a joint debugging test can be performed with the locomotive master control microcomputer and the display screen at any time and is not limited by sites and time, the real-time performance is high, the simulation degree is close to the actual condition, and the debugging efficiency is improved. The systems are simple, and the portability is high.
Description
technical field [0001] The invention relates to a microcomputer combined screen simulation debugging method for a main control system of a locomotive and an electropneumatic braking system, belonging to the technical field of locomotive manufacturing. Background technique [0002] The electropneumatic braking system of locomotives includes two sets of electronic brake valves (large and small brakes), a central processing module (IPM), an I / O interface device and an electrical control unit (EPCU). Compressed air is the driving force of the brake. As an independent system provided by the supplier, the electropneumatic braking system usually communicates with the microcomputer and its display screen of the locomotive main control system through the communication network. In order to simplify the structure of the locomotive system, the complete vehicle manufacturer of the locomotive often needs to integrate the electropneumatic braking system into the main control system of the...
