The elastomers such as property element, sensitive beam generate flexible deformation under external force, make to be pasted onto the resistance strain gage on its surface also with
Same to be deformed, after resistance strain gage deformation, its resistance value will change, then through corresponding measuring circuit, this resistance
Variation is converted to voltage or current value, so as to complete external force to be transformed to the process of electric signal.Pass through the high-precision AD of instrument
Conversion, shows weight.In the prior art, the weighing system used on quantitative package and filling apparatus be typically by
The compositions such as PLC, HMI and weighing instrument are connected by industrial field bus such as 485 buses or ProfiBus inside them,
And the control of weighing system is completed by several microcontrollers, however, it is necessary to carry in actual industrial on-line weighting system
High AD conversion and sample rate and the precision of quantitative package, just there is an urgent need to improve the ability to communicate between single CPU and can for this
By property, for this purpose, we have proposed a kind of Intelligent weighing control instrument, to solve the above problems.
The content of the invention
It is an object of the invention to provide a kind of Intelligent weighing control instrument, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the present invention provides following technical solution：A kind of Intelligent weighing control instrument, including centre
Reason device, PLC control unit, human-computer interface system, dynamic weighing transducer system and dual channel system bus interface, feature exist
In：The central processing unit carries out human-computer interaction by human-computer interface system and user；The PLC control unit is programmed by PC
Unit is connected with central processing unit, and the dynamic weighing transducer system receives real-time weight signal and is sent to the centre
Device is managed, the dual channel system bus interface carries out data biography for connecting the central processing unit and all types of industries equipment
It passs.
Preferably, the dual channel system bus interface includes TCP/IP interfaces and CAN interface.
Preferably, the central processing unit uses ARM 64-bit microprocessors.
Preferably, the Intelligent weighing control instrument uses RTOS as real time operating system.
Preferably, the human-computer interface system uses dot matrix LED touch display screen.
Preferably, using data analysis, the dynamic algorithm of curve matching in the dynamic weighing transducer system, and use
Risc instruction set.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is used as an integrated PLC technology intelligence
Energy Weighing control instrument, the configuration of the present invention is simple, integrated level is high, and compatibility preferably, has good human-computer interaction function and is
System expanded function, supports programming Control, it is ensured that the accuracy and real-time weighed.
Description of the drawings
Fig. 1 is present system block diagram.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment belongs to the scope of protection of the invention.
Referring to Fig. 1, the present invention provides a kind of technical solution：A kind of Intelligent weighing control instrument, including central processing unit,
