The ground control system and a plurality of devices such as a plurality of rocket single machines are networked through a CAN bus network, and a double-bus networking mechanism is adopted. The invention takes the program online upgrade as an application scene, and the ground control system and the single machines on the rocket transmit the upgrade files in batch to realize the online upgrade process of the single machines.
The control bus is responsible for the transmission of the control information of the core single machine node, and the real-time performance and the reliability of the transmission of important information are ensured. The test bus is used as a redundant bus of the control bus, transmits the control information of the core single machine, transmits the measurement data of each single machine node, and completes the transmission and feedback of the control command of each battery node. After receiving the control information, the single-machine node firstly confirms whether the information is the repeated information or not no matter which bus the information comes from, and executes the action if the information is not the repeated information.
In order to ensure that the bus has a low load, the bus rate is set to 500Kbps, the clock crystal oscillator of each single-machine node is required to be an integral multiple of 8MHz, and the time slice distribution scheme is shown in the following table.
TABLE 1 bus Rate time slice Allocation Table
Note: bit time tBit is 1s/500kbps 2000 ns/bit; the crystal clock period T is 1s/8MHz 125 ns.
The CAN bus communication of the control system adopts an extended frame format of CAN2.0B standard. An ID that does not comply with this specification is an illegal command, and the terminal node should discard or report an exception.
And the message on the arrow is transmitted by one or more CAN bus data frames according to the effective data length to be transmitted. Different data frames constituting a message have the same message code, and the data frame numbers increase from 0 in sequence.
Aiming at the 8-byte data field of each data frame, the byte sending sequence of the CAN bus is that the low byte is sent first and then the high byte is sent, and the 8 bits of each byte are sent first and then the low bit is sent.
The bus protocol follows a little-end mode for the encoding and storing mode of the data field, and low bytes are stored in a low address and high bytes are stored in a high address. The encoding of 8-bit single byte data follows a pattern with the upper bits of the data placed in the upper byte bits and the lower bits of the data placed in the lower byte bits.
The CAN bus is a broadcast general channel, various information is transmitted on the bus, and in order to avoid interference of irrelevant information on each execution node, each node single machine must filter CAN bus node information and only respond to the relevant information of the node.
In the whole CAN bus network, irrelevant messages are filtered by utilizing whether D10-D15 of data frame IDs are consistent with the node number of the equipment or not through the identifier filtering function of the CAN bus controller.
