The data of acquisition are passed to PLC control module with current signal, PLC control module is according to itself code value range, instrument amount by collection
Journey, measured current calculate the true value of data.
The transformation of PLC signal is needed by following procedure: physical quantity-sensor signal-standard electric signal-A/D turns
Change-numerical value shows, it is linear signal transformation that the PLC said herein, which is calculated, skips over the included signal conversion process of sensor.
It is assumed that physical quantity is A, range is A0-Am, real-time physical amount is X；Standard electric signal is B0- Bm, real-time tele-communication number is Y；A/D
Transforming numerical is C0-Cm, real time value Z, in this way, B0Corresponding to A0, BmCorresponding to Am, Y correspond to X and Y=f (X), due to
It is linear relationship, show that equation is
Again due to being linear relationship, the math equation Z=f (X) after A/D is converted can be expressed as

Then,After the mathematical operation of PLC instruction calculates, HMI can be posted from result
Project amount is read and is indirectly displayed as in storage, and with same principle, we can input project amount on HMI, then by soft
Part is converted into the standardized value that control system uses.
Further, the parsing and transmitting of data are carried out between the handheld device and communication module using RTU/TCP agreement.
Further, the start and stop of the control module control field device, aperture regulation, frequency adjusting, automatic running, control
System instruction passes to PLC control module, and PLC control module controls field device accordingly.
The acquisition mode of data is connected depending on connection mode by wifi, the mode of acquisition be using Transmission Control Protocol,
PLC control module is connected, corresponding MODBUS instruction is then sent, obtains the data of respective nodes；Bluetooth connection is to pass through hand
The bluetooth of machine and equipment is linked up, and is just had the MODBUS of RTU to instruct, is obtained the data of respective nodes, what data acquisition obtained is floating
Points obtain data rule according to device definition, and the number of specified 2 nodes is carried out 16 systems by the needs that numeric type obtains
Conversion obtains final data in the number for transforming into float type after merging.Boolean categorical data obtains to obtain
The specified node number taken is converted into 2 systems, obtains the number that Rule specifies digit further according to device definition, 0 is vacation, and 1 is
Very.(it similarly sends data to be sent according to the mode reversely converted, in addition bluetooth mode, since it is desired that transmitted by RTU mode,
So the ordered series of numbers for needing additionally entirely to transmit carries out CRC check, 2 check codes for RTU transmitting are obtained), after obtaining data
It by the transfer mode of eventbus, is sent to and specifies received position, finally when calling the interface, reception is called to destroy
Data are shown.
