Abstract

The invention provides a method for removing data interference in program upgrade of electronic equipment. The method comprises the following steps: S1, sending a first signal to multiple electronic equipment; S2, judging whether the first signal is received; if the first signal is received, executing step S3; if the first signal is unreceived, executing step S2; S3, enabling other electronic equipment to stop sending data; S4, judging whether the CAN bus is normal in data transmission; if the CAN bus is normal in data transmission, executing S5; and executing S2 if the CAN does not transmit data; S5, performing program upgrading on the upgraded electronic equipment; S6, judging whether the program upgrading of the upgraded electronic equipment is successful, if the upgrading is successful, executing step S7, and executing S5 if the upgrading is unsuccessful; S7, sending a second signal to other electronic equipment on the CAN bus; S8, judging whether other electronic equipment receives a second signal; if other electronic equipment receives the second signal, executing step S9; and executing step S7 if other electronic equipment does not receive the second signal; and S9, exitingafter the upgrading is successful.

Description

【Technical field】 [0001] The invention relates to the technical field of new energy electric power, in particular to a method for eliminating data interference during program upgrade of electronic equipment. 【Background technique】 [0002] The new energy power industry needs multiple electronic devices to monitor. During the monitoring process, different electronic devices will generate different communication information. For example, multiple acquisition modules, main control modules, display screens and other electronic devices are all connected through a CAN bus transmit communication information. When we upgrade the program of an electronic device, the upgrade file needs to be transmitted through the CAN bus, and the upgrade file is large and continuous. When the data volume of the CAN bus is large, the response information will not be received, resulting in The program update of the electronic device was unsuccessful. [0003] Usually, when the program upgrade of the...
