Problems solved by technology
When the master controller fails, the slave controller can take over the management work of the master controller and continue to run. The integrity of the data information of the server can be guaranteed, but since the data synchronization between embedded systems uses the serial port In the way of working, the data synchronization between embedded systems takes a long time, which will lead to the inconsistency of the embedded system status information of the two controllers

The present application discloses an information synchronization method, which is applied to a slave controller of an electronic device. The information synchronization method includes, when an operation instruction is received from an embedded system of the slave controller, recording the receiving time of the operation instruction; forwarding the operation instruction to the embedded system of the master controller; the embedded system of the slave controller executes the operation corresponding to the operation instruction to obtain the second operation result, and sets the second system state information in the slave controller according to the second operation result; Whether the time difference between the receiving moments is greater than the first preset duration; if so, synchronize the second system state information according to the first system state information; if not, keep the second system state information unchanged. The present application can ensure that the state information of the embedded system of the dual controllers is consistent and improve the stability of data storage. The present application also discloses an information synchronization system, an electronic device and a storage medium, which have the above beneficial effects.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular, to an information synchronization method, a system, a storage medium, and an electronic device. Background technique [0002] Data storage is the key to ensuring the stable operation of business. For industries such as finance, transportation, and telecommunications, it is necessary to maintain the stability of data synchronization information, or the strong consistency of synchronization information. At present, most electronic devices use dual controllers to achieve active and standby redundancy. The controllers include operating systems (such as Linux) running on the CPU, and embedded systems other than those running on the CPU. These embedded systems are cured on the chip. The controller includes two copies of the same control information. If the information is inconsistent, when the operating system obtains the information of the embedded system, it will cause...
