Siemens's wide temperature range type all-in-one in a specific embodiment of the present invention, its model is: EPC T120 C2D, Programmable Logic Controller PLC model is: 6AG1312-5BE03-2AB0, digital quantity input module model is: 6AG1321-1BL00-2AA0, digital output module model is: 6AG1322-1BH01-2AA0, analog input module model is: 6AG1331-7KF02-2AB0, analog output module model is 6AG1332-5HD01-7AB0, radar level gauge model is: 5401AH1E54SPVCAM1C1, electromagnetic flowmeter model is: 8705TSA020C1WOE3B3, the model of pressure transducer is: 3051GP2A2B21AB4E5M5D4HR5, the model of rotating speed transducer is: D421.51u1.
System is in operation and first adopts transmitter that the collection value of each sensor is converted to 4 ~ 20mA analog current value, this current value enters analog input module, through PLC, calculate 6400 ~ 32000 digital quantity, and be stored in internal storage, complete A/D conversion (analog to digital conversion).Then and by PLC internal processes, this value is converted to the analog quantity of 4 ~ 20mA, be shown on touch-screen, complete D/A conversion (digital-to-analog conversion).Finally, the value that the industrial computer programming software Wincc of employing all-in-one inside shows needs, with the form of coordinate curve, is shown in the picture of setting, is convenient to real time inspection; These variablees are stored in the big capacity hard disk that industrial computer carries with the collection period of setting simultaneously, facilitate data storage and print at any time.
One of them embodiment is as follows:
1. the I_DI instruction transformation of the data of analog quantity channel AIW0 being programmed by PLC is DINT data type, and deposits in AC0.
2. use DI_R to be converted to floating number the data in AC0, promote computational accuracy.Because Siemens does not allow integer data to be directly converted to floating number, therefore must be by 1,2 step conversion.
3. by AC0-6400, because being captured in Siemens's 200 series of 4-20mA moved and carried out by coordinate, namely because for 0-20mA, the image data of Siemens S7-200 is at 0-32000, that is to say that the numerical value that every 1mA is corresponding is 32000/20=1600, therefore 4-20mA is exactly 6400-32000 so, input value will be deducted to 6400 movements that complete coordinate.
4. then divided by (DIV_R) 25600, obtain the number percent that input value takies whole input range, 32000-6400=25600,25600 is exactly the input range that 4-20mA is corresponding.
5. then by being multiplied by (MUL_R) 100, the data of 0-100 have just been obtained.By said procedure, the data between 6400-32000 corresponding to the analog signals of input are converted to the data between 0-100, complete linear transformation.
6. the mathematical computations in signal conversion.Suppose that physical quantity is A, scope is A0-Am, and real-time physical amount is X; Standard electric signal is B0-Bm, and electric signal is Y in real time; A/D transforming numerical is C0-Cm, and numerical value is Z in real time.So, B0 is corresponding to A0, and Bm is corresponding to Am, and Y is corresponding to X, and Y=f (X).Owing to being linear relationship, show that equation is Y=(Bm-B0) * (X-A0)/(Am-A0)+B0.Owing to being linear relationship, the math equation Z=f (X) after A/D conversion can be expressed as Z=(Cm-C0) * (X-A0)/(Am-A0)+C0 again.With regard to being easy to, show that the math equation of inverse transformation is X=(Am-A0) * (Z-C0)/(Cm-C0)+A0 so.The X calculating in equation just can directly be expressed as detected physical quantity on display.In PLC, to take S7-200 and 4-20mA be example to the computing method of inverse transformation, and after A/D conversion, the numerical value that we obtain is 6400-32000, and C0=6400, Cm=32000.So, X=(Am-A0) * (Z-6400)/(32000-6400)+A0.For example certain temperature sensor and transmitters sense is-10-60 ℃, with above-mentioned equation, is expressed as X=70* (Z-6400)/25600-10.
7. after the mathematical operation command calculations of PLC, integral type industrial computer can read and directly be shown as quantities from result register.By same principle, can on above-mentioned integral type industrial computer, input quantities, then by software, convert the standardized value that control system is used to.
Finally by integral type industrial computer, shown in real time and store data.This function is programmed every group of data was stored in data in the hard disk of industrial computer according to the cycle of setting by Wincc, also can control in real time and check each data of this system by this software simultaneously.Make that whole acquisition system is more stable, simple operation, cost is low, automaticity is high.
