Problems solved by technology
If the auxiliary system fails again, the locomotive will not be able to continue to operate
In addition, the display screens in the cabs at both ends of the locomotive are independently controlled by the main and auxiliary systems. After redundancy switching, only the display screens at the operating end work normally, and the display screens at the non-operating end will no longer display locomotive information.

Embodiment Construction
[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0044] see figure 1 In the locomotive redundant control system of this embodiment, the main and auxiliary systems respectively include the same power supply board, main control board, CAN board, HDLC board and input and output modules. The input and output modules are composed of independent digital input boards, digital output switch boards...

The invention provides a redundancy control method of a locomotive, which changes a respective single input-output board card of a main system and an assistant system into an input-output module constituted of a digital quantity input-type board card, a digital quantity output-type board card, an analog input-type board card and a frequency amount input board card and correspondingly increases the quantity of HDLC board card buses, wherein the main system simultaneously controls display screens of cabs on two ends. During running, each corresponding board card of the input-output module of the main and assistant systems is detected, and the invalid board card with a failure will be switched to the corresponding board card in the other system through redundancy. If overall redundancy switching is required, the display screens of the cabs on the two ends will be controlled simultaneously by the assistant system. The overall redundancy switching is combined with partial redundancy switching in order to increase a redundancy degree of hardware. Due to strict judgment conditions for the redundancy switching, the main system and the assistant system keep on determining whether the other system exists in the aspect of the hardware; and realization of gapless and accurate redundancy switching is guaranteed in the aspect of software.
Description
technical field [0001] The invention relates to a locomotive redundancy control method, which belongs to the technical field of locomotive manufacturing. Background technique [0002] The locomotive control system manages and controls all the electrical equipment of the locomotive. For the safe and reliable operation of the locomotive, redundant backup must be implemented. The locomotive redundant control system consists of two parts, the main system and the auxiliary system, and each system includes the same hardware. The main system controls the whole vehicle, and the auxiliary system is in hot backup state, receiving real-time status information of the whole vehicle, but does not participate in the control of the whole vehicle. And when the main system breaks down, then switch from the main system to the auxiliary system immediately, the main system stops working, and the whole vehicle is controlled by the auxiliary system. [0003] In the prior art, a locomotive contro...
