The work process of electronic tag resistance multimachine multi-way detecting equipment is as follows：
Electronic tag resistance multimachine multi-way detecting equipment equipment is divided into main MCU and from MCU slaves, and main MCU controls serial ports number
According to detection, and control data communication between MCU and PC, from MCU be mainly used in the measurement to electronic tag resistance with it is upper
Pass；First have to carry out range setting, give main MCU by PC hair data, main MCU is detected to data, if data are not inconsistent hop communication
Agreement, then main MCU error feedback is carried out to PC, have feedback data it can be seen that the position of error in data, convenient change, if data
Meet communication protocol, then main MCU issues range data from MCU, after MCU is detected to data again, if data are not inconsistent
Communication protocol, then carry out error feedback to main MCU, main MCU simultaneously carries out error feedback to PC, for reminding change from MCU
Data are resend, if data fit communication protocol, from MCU reception amount number of passes evidences, and are occurred on PC correct
Then range data can be sent to TLC5615 by feedback from MCU, so that digital-control constant-flow source circuit produces fixed electricity in detection
Stream, range sets shared multiple choices, may diminish to several milliohms to ten ohms, wherein 0.2 Ω range choosing is lifted here
Select and state its principle：
Amplifier magnification ratio is 11 times, and the MSP430 maximum sampled voltage of AD samplings is 3.3V, so VAD=V*11；
So the maximum 0.3V of the V before amplified；And V=I*R labels, so the maximum that make R labels is 0.2 Ω, as long as
The value perseverance for making I is 0.3/0.2=1.5A, you can to achieve the goal；And I=VDA/R sampling resistors, so needing VDA to export I*R
Sampling resistor=1.5*0.5=0.75V；Inspection information understands that TLC5615 output voltage calculation formula is VDA=2*VREF*
N/1024, VREF here is 2.5V, and 153 are taken by calculating N, as long as then inputting 153 from MCU to TLC5615, it is possible to set
Range is 0.2 Ω, and herewith range setting principle is identical for other ranges；Now, setting completed for range, and digital-control constant-flow source output is constant
Electric current I, the principle of calibration and resistance measurement also according to more than below calculates resistance value；Then equipment enters calibrating die
Formula, sends from PC to main MCU and starts calibration command, equally, main MCU and data can be detected from MCU, until all MCU
Untill receiving correct calibration command, so latter two detection test pencil carries out short circuit, and detection switch is pressed, and two test pencils disconnect, and open
Shut-off is opened, and this will detect that the error resistance between test pencil, and this error resistance is stored into MCU, is made when measurement is started
With.Now, calibration mode is over, and equipment can enter the detection pattern of electronic tag resistance.Next, detection switch is pressed
Under, detection starts, and can enter AD samplings from MCU, the magnitude of voltage between electronic tag is converted into digital quantity, when switching off
Afterwards, AD samplings terminate, and institute's measuring resistance value subtracts error resistance during calibration, as real label resistance, so as to produce one group
The resistance value of electronic tag, this group of resistance Value Data can be by being transmitted to main MCU from MCU, and main MCU can be uploaded to PC immediately.Once survey
After amount terminates, until detection switch is pressed again, MCU can be just entered in measurement next time.
