Description
Technical field
The invention belongs to industry internet data acquisition applications technical field, specifically a kind of universal data acquisition units.
Background technique
Data acquisition is the basis of industry internet platform construction, currently, MODBUS agreement has become China's industry certainly
One of the national standard of dynamicization network protocol standard, the product or system of domestic many manufacturers support the agreement, still,
MODBUS agreement is a kind of serial port communicating protocol of standard, only defines the message structure that controller can recognize and use,
In same type instrument, the corresponding register address of same parameters is not consistent, and this requires in actual data acquisition
In, for different product or system, there is different acquisition devices to carry out the reading and transmission of data, cause data collection system
Build longer implementation cycle and higher cost input.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the defects of the prior art, provide a kind of universal data acquisition unit.
The present invention provides a kind of universal data acquisition unit, including configuration software and hardware collector equipment, the configuration
Software is used to be written the hardware collector equipment according to the definition of the different agreement of each producer, and the hardware acquisition equipment is by center
Processor, memory block, communication unit and state instruction are constituted, after the universal data acquisition unit is written in the configuration software,
According to established rule, the data conversion of different manufacturers is exported at uniform data protocol ruleization, simplifies data collection system face
Pair object be unified interface, the output protocol of the universal data acquisition unit can be customized tune according to data system
It is whole, have abundant adaptability.
Preferably, the universal data acquisition unit has communication terminal data buffer storage function, can protect when breaking in the communications
Collected data are deposited in locally-stored area, communication is uploaded again after restoring.
Preferably, the universal data acquisition unit is supported but is not limited to the channel LAN, BN-IOT, GSM, 4G.
Preferably, data collection system is in request data, by the universal data acquisition unit be responsible for two kinds of agreements it
Between argument address conversion, that is, can reach the purpose of unified data interface.
Preferably, all instrument in MODBUS RTU agreement scope can be to be mentioned using all devices of the agreement
For protocol conversion.
Beneficial effect
In MODBUS RTU agreement scope, the present invention can to provide protocol conversion using all devices of the agreement, thus
The cost for simplifying system Construction and maintenance reduces the complexity of system Construction, the efficiency of lifting system operation.
Detailed description of the invention
Fig. 1 is floor map of the invention.
Specific embodiment
Below with reference to the example diagram in present example, the technical solution in the present invention clearly, completely describe.
The present invention provides a kind of universal data acquisition unit, and according to the communications protocol register address table that device manufacturer provides, write-in is logical
With data acquisition device, universal data acquisition unit embedded software according to the relationship between the register parameters and address of write-in,
When reading data, register address of the register address of the parameter into output protocol is remapped, as a result, data acquisition system
System is responsible for the conversion of the argument address between two kinds of agreements in request data, by universal data acquisition unit, that is, can reach unification
The purpose of data-interface.
Embodiment
As shown in Figure 1, a kind of universal data acquisition unit, including configuration software and hardware collector equipment, configuration software
For defining write-in hardware collector equipment according to the different agreement of each producer, hardware acquires equipment by central processing unit, storage
Area, communication unit and state instruction are constituted,, will be different according to established rule after universal data acquisition unit is written in configuration software
The data conversion of producer is exported at uniform data protocol ruleization, and simplifying the object that data collection system faces is unified interface,
The output protocol of universal data acquisition unit based on MODBUS rtu protocol can be customized adjustment according to data system, tool
Standby abundant adaptability.
Preferably, universal data acquisition unit has communication terminal data buffer storage function, can save and adopt when breaking in the communications
In locally-stored area, communication is uploaded the data collected again after restoring.
Preferably, universal data acquisition unit is supported but is not limited to the channel LAN, BN-IOT, GSM, 4G.
Preferably, data collection system is in request data, by the universal data acquisition unit be responsible for two kinds of agreements it
Between argument address conversion, that is, can reach the purpose of unified data interface.
Preferably, all instrument in MODBUS RTU agreement scope can be to be mentioned using all devices of the agreement
For protocol conversion.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Summary of the invention within protection scope.
