The ground control system and a plurality of devices such as single-machine on a plurality of arrows are networked through a CAN bus network, and a double-bus networking mechanism is adopted. The invention uses the online upgrade of the program as the application scene, and the ground control system and the single machine on each arrow transmit the upgrade files in batches so as to realize the online upgrade process of each single machine.
The control bus is responsible for the transmission of control information of the core single machine node, and ensures the real-time performance and reliability of important information transmission. The test bus is used as a redundant bus of the control bus, and transmits the measurement data of each single-unit node in addition to the control information of the core single-unit, and simultaneously completes the control command transmission and feedback of each battery node. After receiving the control information, the stand-alone node firstly confirms whether the information comes from any bus or not as repeated information, and if the information does not come from the repeated information, the stand-alone node executes the action.
In order to ensure that the bus is low in load, the bus speed is set to be 500Kbps, the clock crystal oscillator of each single node is required to be an integral multiple of 8MHz, and the time slice allocation scheme is shown in the following table.
Table 1 bus rate time slice allocation table
Note that: bit time tbit=1 s/500 kbps=2000 ns/bit; the clock period T=1s/8MHz=125ns.
The CAN bus communication of the control system adopts an extended frame format of the CAN2.0B standard. An ID that does not follow this specification is an illegal instruction and the end node should discard or report the exception.
And the on-arrow message 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 number, and the data frame numbers increase in sequence from 0.
For the 8-byte data field of each data frame, the byte transmission sequence of the CAN bus is that the low byte is transmitted first, then the high byte is transmitted, and the 8 bits of each byte are transmitted first, then the low bit is transmitted.
The bus protocol follows a small-end mode for the coding and storage mode of the data field, the low bytes are stored in the low addresses, and the high bytes are stored in the high addresses. Encoding 8-bit single byte data follows a pattern in which the high order bits of data are placed in the high order bits of bytes and the low order bits of data are placed in the low order bits of bytes.
The CAN bus is a broadcast universal channel, various information is transmitted on the bus, and in order to avoid the interference of irrelevant information on each execution node, each node stand-alone machine has to filter the CAN bus node information and only responds to the information related to the node.
In the whole CAN bus network, by the identifier filtering function of the CAN bus controller, whether D10-D15 of the data frame ID is consistent with the node number of the device is utilized to filter irrelevant information.

step B, the ground control system receives the response and sends binding data;
step C, the arrow stand-alone receives the binding data and judges whether a data checking instruction is received or not, if the arrow stand-alone receives the data checking instruction, data checking is carried out, and a corresponding response is sent;
step D, the ground control system judges whether the response confirms the binding data to be correct or not, and if so, the ground control system inquires the rest binding data;
e, when the ground control system data are bound, sending a file verification instruction to the single machine on the arrow, performing file verification by the single machine on the arrow, and sending a corresponding response;
step F, the ground control system judges whether the response determines that the file verification is correct, if so, the ground control system sends a flash erasing instruction, and the single machine on the arrow erases the flash and sends a corresponding response;
step G, the ground control system judges whether the response determines whether the flash erasure is correct, if so, a flash writing instruction is sent, the single machine on the arrow writes the flash, and a corresponding response is sent;
step H, the ground control system judges whether the flash writing is correct or not according to the response, and if so, the message writing process is ended;
the block data transmission message reading process comprises the following steps:
step a, a ground control system sends a reading instruction, an arrow stand-alone machine receives and replies a corresponding reading instruction response, and the ground control system receives the reading instruction response within a set time;
b, if the ground control system receives the response of the reading instruction within the set time, the arrow stand-alone machine sends data, and the ground control system receives the data;
step c, the ground control system sends a verification instruction, if the arrow stand-alone machine receives the data verification instruction, data verification is carried out, and a corresponding response is sent;
step d, the ground control system judges whether the response determines the reading of the data is correct, and if so, the ground control system inquires the rest read data;
step e, when the ground control system data is read, sending a file verification instruction to the single machine on the arrow, and carrying out file verification by the single machine on the arrow and sending a corresponding response;
and f, the ground control system judges whether the response determines that the file verification is correct or not, and if so, the message reading process is ended.
