Detailed Description
The first embodiment is as follows:
the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the multi-protocol data integrated communication device based on serial communication disclosed by the invention comprises a rectangular housing 1, a data processor located in the housing 1, and eight incoming line interfaces 2, one outgoing line interface 3 and one configuration interface 4 which are arranged on the same side of the housing 1. The data processor is a single chip microcomputer with a data integration processing function, and is preferably a single chip microcomputer of STM32F103VCT6 type. The data processor is internally stored with a plurality of receiving subfunctions and output subfunctions corresponding to communication protocols, the communication device is connected with an upper computer through a configuration interface 4, and the upper computer configures the corresponding receiving subfunctions for each incoming line interface 2 and each outgoing line interface 3, thereby realizing that the same interface is suitable for receiving data of a plurality of communication protocols.
For example, the communication protocol a is as follows: 1-bit start bit, 8-bit data bit, 1-bit parity bit and 1-bit stop bit;
the communication protocol B is as follows: 1 bit start bit, 4 are data bit, 1 bit error check bit and 1 bit stop bit;
the communication protocol C is as follows: 1-bit start bit, 1-bit check bit, 8-bit data bit, and 1-bit stop bit.
When receiving the detection data of the detection data output by using the communication protocol A, configuring the mode of receiving the data by the corresponding incoming line interface 2 as a receiving sub-function corresponding to the communication protocol A, extracting the 2 nd-9 th bit data as the detection data, and outputting the detection data in the communication protocol transmission mode corresponding to the output sub-function through the outgoing line interface 3.
In order to enable the outgoing line interface 3 to output the data received by the incoming line interfaces 2, the communication protocol code corresponding to the output subfunction sequentially includes a start bit, two stop bits, and a data bit located between the start bit and the stop bit, and the data of each group of data bits corresponds to the incoming line data of the single incoming line interface 2 and is configured with a blocking bit. Wherein the start bit '1' is valid, the stop bit '01' is valid, the partition bit adopts a four-bit partition bit, and the partition bit '0000' is valid.
If the three incoming line interfaces 2 are respectively configured as receiving subfunctions corresponding to the communication protocol a, the communication protocol B and the communication protocol C, the data codes are as follows:
1 11010110 1 1；
1 1101 0 1；
1 1 11011011 1；
the detection data received by the three incoming line interfaces 2 are respectively: "11010110", "1101" and "11011011", the way of outputting three sets of data by using the communication protocol corresponding to the output sub-function is:
1 11010110 0000 1101 0000 11011011 0000 01；
in order to increase the security during the data transmission process, adding check bits to the communication protocol corresponding to the output subfunction is a conventional means in the field, and is within the scope of the description of the present embodiment, and is not described herein again.
The manner of configuring the receiving subfunction for each incoming line interface 2 by adopting the upper computer is as follows:
if the receiving sub-function to be called is printf (a) and a is data received by the printf sub-function, the data receiving mode of the interface is as follows:
Int main()
{ printf（a）;return a;}
the data received by each incoming line interface 2 is obtained by the "a" value returned by each incoming line interface 2.
Furthermore, the data processor is also connected with a HART communication module, and regional networking of the communication device is realized through the HART communication module, so that the number of field communication lines is reduced, and the arrangement cost of the communication device is reduced.
Furthermore, a read-write interface 5 is further arranged on the shell 1, and workers can update programs in the data processor through the read-write interface 5.
As can be seen from the above, when data acquisition needs to be performed on multiple devices, first, a subfunction for receiving and sending data is configured for each of the outgoing line interface 3 and the incoming line interface 2 through the configuration device, so that data entering through the incoming line interface 2 can be received in a manner of correspondingly receiving the subfunction, and data can be output in a manner of correspondingly outputting the subfunction when data appears at each of the outgoing line interfaces 3, thereby realizing that detection data of detection devices with multiple communication protocols is output in a unified communication manner.
Example two:
the present embodiment is different from the first embodiment in that:
the communication protocol code corresponding to the output subfunction comprises a start bit, a flag bit, a stop bit and a data bit positioned between the flag bit and the stop bit in sequence. Wherein the start bit "1" is valid, the stop bit "01" is valid, the flag bit is provided with three bits, and the value of the flag bit corresponds to the label of the corresponding incoming line interface 2.
Example three:
the present embodiment is different from the first embodiment in that:
as shown in fig. 3, the communication device includes a display screen 6 for displaying the communication protocol of each interface and a configuration button 7 cooperating with the display screen 6, and the display screen 6 is located on the upper surface of the communication device so that the communication protocol configuration of each interface of the communication device can be visually observed by a utility person.
