If replying correct, you can stop position number is confirmed, to obtain the complete parameter of serial communication.
S4, corresponding equipment letter is obtained according to the corresponding register address of acquisition request, then by parsing register address
Breath.
Serial communication between equipment detection terminal and equipment is as unit of a character, and character is started with start bit, tightly
The lowest order of data word is connect, data word has 7-9 data bit, is terminated with the highest order of data word, immediately check bit after data bit,
Check bit is a kind of in no parity check position, odd parity bit or even parity bit, is finally stop bits, and stop bits is 1 or 2 stop position；
The character data frame format of serial communication is as follows：
1 start bit
7,8 or 9 data bit
No parity check position, odd parity or even parity bit
1 or 2 stop position
Detection terminal ignores the 2nd stop position；The baud rate scope of serial communication is 9600-115200bps, wherein conduct
Standard is totally 6 kinds of 9600bps, 14400bps, 19200bps, 38400bps, 57600bps and 115200bps.It is first when detection
Ignore stop position number, therefore the parameter of serial communication shares 54 kinds of combinations.
In step S1, baud rate, data bits and even-odd check will be received and be set as different values, single character is taken turns
It askes.When there is no mistake, you can be tentatively judged as that baud rate, data bits and even-odd check are correct.
In step S2, the data frame of modbusRTU communications protocol includes that request and response, a request originate in 3.5
Bytesfree, the immediately information frame of 8 bytes, rear 2 bytes of information frame are CRC checks, are also finally 3.5 bytesfrees.
By being not less than the free time of 3.5 bytes before and after identification frame, the information frame of 8 bytes is selected, if CRC check is correct, then is sentenced
Second byte of disconnected information frame（That is function code）Whether it is 1,2,3,4,5,6 verification communications parameters.
Fig. 5 is the example for the data frame that 19200 baud rates are obtained by poll, this is one and reads to deposit to station number 1
Device 71（47h）~76（4Ch）Claim frame.
In step S3, for 9600 minimum baud rate, the frame data time includes front and back free time, about 0.09 second.
If always existing data frame transfer on interface, the longest a cycle of poll about 5 seconds.But it actually often not deposits always
In data frame, it is also possible to which the reply data frame of modbus slave stations is long, therefore the time waited for is longer.
The method parsed in step S4 is register address to be carried out individual data 16BIT respectively and Double Data 32BIT is adopted
Collection, reconvert carry out comparison judgement at decimal floating point number.
An error range is set when comparison, the numerical value in this error range will be labeled.It can also be automatically to every
A register is compared, and is judged again after being saved in file.
The utility model has the advantage of：
1. the control chip using microcontroller as detection terminal not only meets the requirement of equipment health control detection, and
And detection terminal can be logical with high in the clouds in a manner of the realization WebService or HTTP+JSON directly on the microcontroller of no operating system
Letter is not necessarily to special configuration server, effectively reduces cost.
