and writing the error code and the error value into an error response frame to obtain error response data, and sending the error response data to the EMS energy management system.
7. The EMS and BMS transmission protocol method of claim 1, wherein after the determining whether the protocol identifier is an ETH protocol identifier, further comprising:
and if the command is not the ETH protocol identifier, sending a data request command to the EMS energy management system for reacquiring the character data of the data read-write command.
8. An EMS and BMS transmission protocol system, comprising:
an EMS energy management system and a BMS battery management system;
the EMS energy management system is used for sending a data read-write instruction to the BMS battery management system based on a TCP/IP protocol;
the BMS battery management system is used for receiving the data reading and writing instruction, reading a protocol identifier of the data reading and writing instruction, and judging whether the protocol identifier is an ETH protocol identifier, wherein the ETH protocol identifier comprises: the method comprises the following steps that a TCP/IP protocol is used between EMS and BMS to transmit character strings of an ETH physical layer communication interface protocol;
if the read-write instruction is an ETH protocol identifier, reading a function code, an equipment address and a register address of the data read-write instruction;
judging whether the function code is a preset write-in function code;
if the function code is written, reading a register value of the data read-write instruction, writing the register value into a register address in the equipment address according to an execution instruction corresponding to the function code, and sending a command of successful modification to the EMS energy management system;
and if the write-in function code is not the write-in function code, reading a register value of the register address in the equipment address, and sending the register value to the EMS energy management system.
9. An EMS and BMS transmission protocol device, comprising: a memory having instructions stored therein and at least one processor, the memory and the at least one processor interconnected by a line;
the at least one processor invokes the instructions in the memory to cause transmission protocol devices of the EMS and BMS to perform the transmission protocol method of the EMS and BMS according to any of claims 1-7.
10. A computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the EMS and BMS transmission protocol method according to any one of claims 1 to 7.
