Abstract
The invention discloses a kind of communication protocol recombination methods, and recombination register setting area and data recombination zone are added in existing protocol, wherein recombination register setting area is for being arranged register information, the data recombination area is for storing register data.Communication protocol recombination method provided by the invention has scalability, low cost, the advantage of high efficiency communication process, especially when a variety of intelligence instruments are communicated using the networking of Modbus-RTU communications protocol.
Description
Technical field
The present invention relates to information communication processing technology field, in particular to a kind of communication protocol recombination method.
Background technique
With the development and update of intelligence instrument, many producers are faced with the replacement upgrading of new old product, in escalation process
In there is a problem that new and old edition function and communication protocol are compatible, while the same equipment needs to adopt in different use occasions
The performance data of collection causes to need to acquire several times when data are transmitted and read there are different, leads to data acquisition speed
Rate and efficiency reduce, and are especially easy to influence data timeliness in multiple equipment networking.
Change equipment bottom communication data protocol is allowed to adapt to each occasion acquisition demand, not only increase equipment development cost and
Period also increases the maintenance difficulties of equipment.
Summary of the invention
To solve the above problems, the present invention provides on the basis of not changing original communication protocol content and proposes one kind
Communication protocol recombination method to solve device protocol compatibility issue, while also providing higher efficiency for data transmission and fitting
It is wider with property.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of communication protocol recombination method, comprising the following steps:
1) recombination register setting area and data recombination zone, are added in existing protocol, wherein the recombination register is set
Area is set for register information to be arranged, the data recombination area is for storing register data；
2), according to the setting in recombination register setting area, recombination data is successively updated to deposit data recombination area；
3) when, data communication transmission is read, data recombination area register address is directly read, to return to data after recombination
Group.
Optionally, the register information includes one or more setting groups, and each setting group rises including register
Beginning address, register address 1~register address N, wherein N is up to 255；
Data recombination area quantity and the setting group quantity Matching, and the data length in the data recombination area is pair
Register address 1 should be set in group the sum of to register address N data byte.
Optionally, recombination register setting area is read-write region.
Communication protocol recombination method provided by the invention has scalability, low cost, the advantage of high efficiency communication process,
Especially when a variety of intelligence instruments are communicated using the networking of Modbus-RTU communications protocol, and there are following features:
1) this method, which is not changed, sends code and data transmission format protocol；
2) original communication protocol content, compatible original communications protocol content are not changed；
3) do not increase original function agreement, only legacy data sequence is grouped and is reconfigured, data group has been formed
Continuously；
4) recombination zone length is not limited, and each setting group length can be inconsistent；
5) original discontinuous storing data can be realized it is continuous read, can an instruction read, raising communication efficiency；
According to These characteristics, the present invention can guarantee on the compatible original base of device protocol that it is not necessary to modify logical in use
Protocol format is interrogated, legacy data is re-started and is recombinated using after upper selection, to reach the high efficiency of information transmission.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is that the embodiment of the present invention realizes structure chart.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of communication protocol recombination method, comprising the following steps:
1) recombination register setting area and data recombination zone, are added in existing protocol, as shown in table 1, the recombination is posted
It is 0xAC00~0xAFFF that area's register address, which is arranged, in storage, for register information to be arranged；As shown in table 2, the data weight
Group area's register address is 0xB000~0xBFFF, for storing register data；
2), according to the setting in recombination register setting area, recombination data is successively updated to deposit data recombination area；
3) when, data communication transmission is read, data recombination area register address is directly read, to return to data after recombination
Group.
Optionally, the register information includes one or more setting groups, and each setting group rises including register
Beginning address, register address 1~register address N, wherein N is up to 255, as in table 11 recombination data of setting group storage deposit
Device initial address is 0xB000, and 1 data length of data recombination area is 1 register address 1~register address N1 data of setting group
Byte summation, data recombination area quantity and the setting group quantity Matching make other setting groups respectively correspond distribution corresponding
Memory block, and the data length in the data recombination area is to be correspondingly arranged in group register address 1 to register address N data word
The sum of section, such as data recombination zone 1, data length is that 1 register address 1~register address N1 data byte of setting group is total
With.
When reading data, corresponding data recombination zone data directly can be read according to recombination data area, can once read each
Setting group recombination zone data.1~N of each setting group register can be different, but all support function, each setting group leader for this agreement
Degree can also be not quite similar.
Optionally, recombination register setting area is read-write region.

It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
