The invention provides an on-rocket communication method and system, computer equipment and a storage medium. The method comprises the steps that an EtherCAT communication master station generates a target communication data frame according to a current telemetering instruction set and an EtherCAT communication protocol; the EtherCAT communication master station sends the target communication data frames to the EtherCAT communication slave stations in sequence through a dual-redundancy communication channel; the EtherCAT communication slave station analyzes the target communication data frame to obtain a telemetering instruction matched with the EtherCAT communication slave station; the EtherCAT communication slave station executes the telemetering instruction and generates response data; and the EtherCAT communication slave station replaces a telemetering instruction in the target communication data frame with the response data to obtain a target response data frame, and sends the target response data frame to the EtherCAT communication master station. Thus, the problems of low transmission rate and small transmission data volume of on-rocket communication in the prior art are solved, and the transmission rate and the transmission data volume are improved.
Description
technical field [0001] The present invention relates to the technical field of on-arrow communication, in particular to an on-arrow communication method, system, computer equipment and storage medium. Background technique [0002] In the field of aerospace, with the rapid advancement of defense and aerospace technology, the topology of the control system on the arrow has gradually developed from a single control to a control system between multiple devices and multiple platforms. In order to meet the complex topology of the data communication system between spacecraft, the The diversity, reliability, real-time and high-speed transmission of data put forward higher requirements. However, traditional aerospace field buses, such as 1553B, RS485, RS232, and CAN, have disadvantages such as high cost, low transmission rate, small amount of transmitted data, and the need to reduce the rate for long-distance transmission. [0003] It can be seen that the arrow-up communication in t...
