Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of pseudo-function means of communication, sets a kind of pseudo-function structure,
Using the thought for calling other side's function, when external demand changes, it only need to change corresponding processing function, reduce program and open
The workload of hair and debugging, to improve the flexibility and convenience communicated between equipment and host computer.
The invention is realized in this way：A kind of pseudo-function means of communication, including：
Step S1, the format of pre-specified communication packet, the head for wrapping communication mainly by total length, device network number,
Device node number, substation number and function coding are constituted；
Step S2, the variant of the given function parameter number sent and each parameter is needed according to practical communication command
Value, the variant value are the actual storage byte of corresponding parameter；
Step S3, the coding of function required for equipment is listed, each function is listed according to function coding, each function is corresponding
One function command, and function coding, function parameter and the corresponding relationship of function command three are stored in communication packet
It is interior, so that communication packet is formed pseudo-function；
Step S4, host computer and the equipment are mutually sent out communication packet, equipment and host computer and are carried out according to the information in communication packet
Communication, and according to the power function of function coding, function parameter and the corresponding relationship of function command three calling equipment
To execute corresponding function command.
Further, it the invention also includes step S5, when the function command changes, need to only modify in communication packet
Function coding, function parameter or function command in corresponding relationship.
Further, the total length occupies 4 bytes, and the device network number occupies 2 bytes, the device node
Number 2 bytes are occupied, substation number occupies 2 bytes, and the function number occupies 4 bytes.
The invention has the advantages that：The header information that the present invention is wrapped by prespecified communication, with anchor-frame
Format, and function coding, function parameter and the corresponding relationship of function command three are stored in communication packet, make to communicate
Packet forms pseudo-function, equipment function can be called by pseudo-function, when external demand changes, as function command becomes
Change, it is only necessary to change corresponding processing function, also only be told without developing a new driver again, and when debugging logical
The pseudo-function definition for interrogating the part that other side changes, greatly reduces the workload of debugging, improves and leads between equipment and host computer
The flexibility of news.
Specific embodiment
Include in the preferred embodiment of the pseudo-function means of communication of the invention：
Step S1, the format of pre-specified communication packet, the head for wrapping communication mainly by total length, device network number,
Device node number, substation number and function coding are constituted；In a specific embodiment, it is arranged as follows：The total length occupies 4
