Coordination control method of double-main-control-board circuit

Abstract

The invention discloses a coordination control method for a double-main-control-board circuit. The method comprises steps that a first working instruction is obtained through a first main control board, and a first working task is transmitted to an external working module or a second main control board according to the first working instruction; when the second main control board receives the first work task, the second main control board controls the external work module according to the first work task; and / or, the second main control board obtains a second working instruction and sends a second working task to the external working module or the first main control board according to the second working instruction; and when the first main control board receives the second work task, the first main control board controls the external work module according to the second work task. According to the method, when the load interfaces are not enough, the two mainboards are used for communication joint debugging, so coordination control of the unit is realized, the utilization rate of main control resources is realized, the situation that main control hardware needs to be designed for the unit again and the period is too long is avoided, and working reliability of the unit is improved.

Description

technical field [0001] The invention relates to the technical field of main control board control, in particular to a coordinated control method for dual main control board circuits. Background technique [0002] In the traditional technology, when dual main control boards are used for control, the other main control board is usually used as the load driving board, and there is no actual main control logic for control. This control method has several problems: first, when the load interface of the main control board is not enough, the coordinated control of the unit cannot be realized; second, if coordinated control is required, it is usually necessary to redesign the main control hardware for the unit. The cycle is too long; finally, in the traditional dual control method, when one motherboard is broken, the other motherboard cannot work independently. It can be seen that the traditional dual main control board technology has a great impact on the reliability and effective...

Problems solved by technology

This control method has several problems: first, when the load interface of the main control board is not enough, the coordinated control of the unit cannot be realized; second, if coordinated control is required, it is usually necessary to redesign the main control hardware for the unit. The cycle is too long; finally, in the traditional dual control method, when one motherboard is broken, the other motherboard cannot work independently

It can be seen that the traditional dual main control board technology has a great impact on the reliability and effectiveness of the unit's work.
