Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a processing method of multiple communication protocols of an IR46 smart meter in an embodiment of the present invention, which specifically includes the following steps:
s101, starting a serial port interrupt service program, and identifying a serial port interrupt request mark;
specifically, a serial port interrupt service program is executed, and whether a serial port receiving interrupt flag RI satisfies RI 1 is judged; if yes, executing step S102;
s102, reading serial port data received by a serial port, storing the serial port data into a serial port communication cache, and updating a first serial port communication cache pointer into a second serial port communication cache pointer;
specifically, assuming that a first serial communication cache pointer when the serial data is not received is a, the number of bytes of the serial data is N, and every time a byte of the serial data is read, adding 1 to the first serial communication cache pointer, storing data corresponding to the byte of the serial data in the serial communication cache, and when the complete serial data is received, generating a second serial communication cache pointer as a + N.
It should be noted that the first serial communication buffer pointer points to an address of the serial communication buffer, and when one byte of the serial data is read, an address offset occurs in the serial communication buffer once, so as to store data corresponding to the one byte of the serial data.
It should be noted that, when the serial port data is read, the serial port interrupt service program clears the serial port reception interrupt flag RI to zero, and waits for receiving the next serial port data.
S103, starting a main program, and judging whether a serial port data processing pointer is consistent with the second serial port communication cache pointer or not; if the serial port communication is consistent with the serial port communication, judging that no data is updated, and executing the step S103; if not, judging that data updating exists in the serial port communication, and executing the step S104;
specifically, assuming that the serial data processing pointer is a, the serial data processing pointer is compared with the second serial communication cache pointer a + N generated in step S102, and it is determined that the two pointers are inconsistent and have a difference of N, so that it is determined that there is data update in the serial communication, and the number of bytes of the serial data is N.
If the serial port data processing pointer is compared with the first serial port communication cache pointer A when the serial port data is not received, the serial port data processing pointer is consistent with the first serial port communication cache pointer at the moment, therefore, no data update on serial port communication is judged, and the main program returns to continuously inquire and judge whether the serial port data processing pointer is consistent with the second serial port communication cache pointer.
It should be noted that, under the condition that there is no data update in serial communication, the second serial communication buffer pointer is still the first serial communication buffer pointer when the serial data is not received.
S104, reading the serial port data by the main program;
specifically, the main program sets reading of bytes of the serial port data one by one.
S105, judging whether the serial port data is consistent with frame headers of all communication protocols supported by the meter; if yes, go to step S106; if not, the step S105 is executed;
specifically, it is known that the number of bytes of the serial port data is N, and the serial port data processing pointer is a.
Reading the data of the first byte of the serial port data, judging whether the data are consistent with the frame headers of all communication protocols supported by the meter, and if so, executing the step S106; if the serial port data processing pointer is not consistent with the serial port data processing pointer, the serial port data processing pointer is updated to be A +1, the data of the first byte is lost, the byte number of the serial port data is N-1 at the moment, and the step S105 is executed again;
continuously reading the second byte of the serial port data, judging whether the second byte of the serial port data is consistent with the frame headers of all communication protocols supported by the meter, and if so, executing the step S106; if the serial port data processing pointer is not consistent with the serial port data processing pointer, the serial port data processing pointer is updated to be A +2, the data of the second byte is lost, the byte number of the serial port data is N-2 at the moment, and the step S105 is executed again;
judging in the loop until the M +1 (M +1 < N) th byte of the serial port data is judged to be consistent with all the frame headers of the communication protocols supported by the meter, executing step S106, wherein the serial port data processing pointer is A + M and the byte number of the serial port data is N-M;
it should be noted that, if it is determined that the nth byte of the serial data is inconsistent with the frame headers of all communication protocols supported by the meter, the serial data processing pointer is a + N, and the main program stores that the current serial data processing pointer is a + N and then exits the determination.
It should be noted that, after it is determined that the data of the current byte of the serial port data is inconsistent with the frame headers of all communication protocols supported by the meter, the data of the current byte of the serial port data is discarded, and then the procedure returns to step S105, so as to ensure that the main program reads the data of the next byte of the serial port data at this time.
S106, acquiring first serial port data based on a frame header matching result;
specifically, when the data of the M +1 (M +1 < N) th byte of the serial port data is judged to be consistent with the frame headers of all communication protocols supported by the meter, the first serial port data with the number of bytes N-M is obtained, and the first serial port data is composed of the last N-M bytes of the serial port data with the number of bytes N.
S107, matching the first serial port data with frame formats of all communication protocols supported by a meter to obtain a first communication protocol to which the serial port data belongs;
specifically, given that data corresponding to M +1 th byte to nth byte in the serial port data with the byte number N is the first serial port data, here, the description is still performed by replacing the first byte of the first serial port data with the M +1 th byte of the serial port data, as follows:
according to the step S105, it is determined that the M +1 th byte of the serial data matches the frame headers of all communication protocols supported by the meter, and frame format matching is performed between the M +2 th byte of the serial data and the nth byte of the serial data and all communication protocols supported by the meter to obtain a first communication protocol to which the serial data belongs, where the first communication protocol is one of all communication protocols supported by the meter.
It should be noted that, the current serial port data processing pointer is generated as a + N by adding the corresponding serial port data processing pointer a + M to the byte number N-M of the first serial port data, and the main program records the current serial port data processing pointer a + N. And when the main program executes a new round of cycle judgment, the current serial port data processing pointer A + N is taken as a judgment condition.
It should be noted that, when the first serial port data is matched with the frame formats of all communication protocols supported by the meter, the judgment of the frame end and the check code is included.
And S108, analyzing the serial port data according to the first communication protocol, generating a reply frame of the serial port data, and sending the reply frame of the serial port data out through a serial port.

S109, waiting for receiving next serial port data, analyzing the received next serial port data according to the first communication protocol, generating a reply frame of the next serial port data, and sending the reply frame of the next serial port data out through a serial port.
It should be noted that, after the communication protocol matching is performed on the serial port data, the matched communication protocol is continuously used to process the next serial port data, so as to complete the data interaction.
In a specific implementation process, when a serial port data request is sent to an IR46 intelligent electric energy meter for communication, the IR46 intelligent electric energy meter receives the serial port data based on a serial port interrupt service program, the IR46 intelligent electric energy meter judges the serial port data based on a main program, the serial port data is a communication protocol supported by the serial port data matching meter, a reply frame of the serial port data is sent to a sender according to the communication protocol, and communication between the sender and the IR46 intelligent electric energy meter is established at the moment.
