Problems solved by technology

[0003] In general, the controllers in traditional redundancy systems mostly adopt an integrated design. In addition to the signal acquisition, data processing, and control algorithm implementation related to actuation control, the redundancy management algorithms are all implemented on the controller, which affects the computing power of the controller. The requirements are high. In addition, the integrated design has poor portability. It is difficult to port the code when replacing the program (such as changing the MCU chip type), and the system has poor flexibility.
In addition, the existing redundancy systems often use point-to-point connection or dedicated bus, the wiring is complicated and the bus utilization rate is not high

The redundancy system comprises a first redundancy equipment and at least one second redundancy equipment. The first redundancy equipment comprises a first controller and a first programmable module; the first controller is connected with the first programmable module through a communication interface; the first programmable module performs data transmission with the at least one second redundancy equipment and a downlink execution unit through at least one redundancy bus; wherein at least two kinds of data are respectively transmitted between the first programmable module and the at least one second redundancy equipment and between the first programmable module and the downlink execution unit through the same redundancy bus in different time periods. The programmable module serves as a function extension peripheral of the controller, the data processing speed and the system flexibility can be improved, in addition, at least two kinds of data are transmitted in different time periods through the same redundancy bus, the bus utilization rate can be improved, and the wiring complexity is simplified.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a redundancy system, a redundancy management method and a readable storage medium. Background technique [0002] Redundancy technology is one of the design methods for system or equipment to obtain high reliability, high security and high survivability. Especially when the quality and reliability of components or parts are relatively low, and the reliability requirements of equipment cannot be met by general design, redundancy technology has important application value. [0003] In general, the controllers in traditional redundancy systems mostly adopt an integrated design. In addition to the signal acquisition, data processing, and control algorithm implementation related to actuation control, the redundancy management algorithms are all implemented on the controller, which affects the computing power of the controller. The requirements are high. In addition...
