Description
Technical field
The present embodiments relate to industrial instrument mechanics of communication, more particularly to a kind of data transmission method of instrument slave computer
And device.
Background technology
At present, industrial circle is due to the raising of automaticity, and most instrument can all carry data remote function, allusion quotation
Type is the slave computer for needing to be connected from instrument, transfers data to host computer.
In industry spot, generally by the data transmitted required for the slave computer of different instrument individually or parallel connection upload to it is upper
Machine.The host-host protocol of slave computer and host computer can select Modbus agreements.Although the data format of Modbus agreements is disclosed,
The data content that specific instrument slave computer need to be communicated, and had nothing in common with each other because of the instrument and field requirement of different companies.
In actual industry spot, the instrument of same application environment is not only for a company, the instrument of different company
The parameter setting of table is typically different.In general, the instrument of same company is when dispatching from the factory, and corresponding parameter has been set
Set, user can not be modified.Field requirement can limit the specific several groups of data in the measured total data of instrument transmission,
And arrange, specifically while transmitting the parameters such as the data format and register position of data to instrument and having in particular order
Ask, these are limited the transmission requirement of data by host computer.
In order to ensure communication be normally carried out, it is necessary to solve the content of parameter of instrument slave computer and live data to be transmitted and
Not the problem of requirement of its parameter is not inconsistent.At present, prior art mainly ensures being normally carried out for communication by following three kinds of modes：On
Position machine constantly changes program, to adapt to the communications protocol of different instrument slave computer；Instrument producer is according to the agreement of different user
It is required that, program is constantly updated, to adapt to the communications protocol of different host computers；Increase protocol converter.
There is following drawback in three of the above mode：Increase the operation content of host computer, be also unfavorable for same section unification
Management；Instrument producer needs to constantly update program according to order, is unfavorable for unification and the readability of program, and difficult management expends
Manpower, causes situation about getting half the result with twice the effort；Increase cost.

Embodiment five
Fig. 5 is a kind of flow chart of the data transmission method for instrument slave computer that the embodiment of the present invention seven is provided.This implementation
Example can there is provided a kind of preferred embodiment based on above-described embodiment.This method includes：
Step S510, understanding client agreement requirement；
Wherein, client agreement requirement typically refers to the protocol requirement of site of deployment, specifically may include communication data type,
Sequentially, form and/or register original position.
Step S520, the communications parameter into instrument slave computer set menu；
Wherein, preferably menu may be configured as touch or button, equipped with liquid crystal display, user-friendly.
Communication data needed for step S530, selection；
Wherein, one group or several groups of data, such as temperature, rotating speed and/or pressure are selected according to the protocol requirement of client.
Step S540, a newly-built communication data；
Wherein, select one group or several groups of data are established as to the communication data of an entirety.
Step S550, the serial number for selecting data；
Wherein, client agreement requirement has setting to the order of each data, such as first transmits temperature, then transmits pressure, most
After transmit rotating speed.So the serial number of temperature is 1, so the serial number of pressure is 2, so the serial number of rotating speed is 3.
Wherein, flexible configuration preferably is carried out by the menu structure of specific instrument, data amount check can also be arranged by designer,
Can be according to liquid crystalline type and size, using different selections and numbering.Such as can be simply in the way of 1~n pair
Communication data is numbered.If repeated number value then reports an error, and order up and down is carried out to communication data using button exchanges realization order
Reformation.
Wherein, in the program of single-chip microcomputer, the corresponding data of Modbus can be carried out according to the order of selected data in menu
Autonomous arrangement (data format is identical, in a floating-point format exemplified by), due to user be typically all when register is read from
0001 starts, so only needing to according to newly-generated data communication.Data format preferably for communication data and logical
The register initial address of data is interrogated, can also be selected in a menu.Because the direct-reading effect of floating data more facilitates,
And the universal reading since 0001 of register, so the data format and register original position of the communication data of instrument slave computer
Typically it is defaulted as both selections.
Step S560, the order numbered by selected communication data reset communication data；
Wherein, communication data is regenerated according to the data sequence number of selection.Actual communication data is numbered by communication data
Order is determined.After communication data numbering is set, communication data is numbered the order set according to communication data and assigned again
Value, putting in order for such communication data can just match with field requirement.
Step S570, exit communication data actions menu；
Wherein, require to reset after communication data according to client agreement, exit communication data actions menu, carry out next step number
According to transmission.
Step S580, Modbus routine call communication data；
Wherein, the communications protocol of data transfer is selected, can be Modbus communications protocol.
Step S590, the transmission for carrying out communication data.
Wherein, the communication data after being reset according to selected communications protocol transmission.How Modbus communication program is realized
Just repeat no more.
The simple programming that the replacement to communication data is carried out is the following is, different instrument and different processor are pressed in actual programming
Performance handled.
