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 slave, and main MCU controls serial ports number
According to detection, and control data communication between MCU and PC, from MCU be mainly used for the measurement to electronic tag resistance value with it is upper
It passes；It first has to carry out range setting, gives main MCU by PC hair data, main MCU detects data, if data are not inconsistent hop communication
Agreement, then main MCU carries out error feedback to PC, has feedback data to can be seen that the position of error in data, facilitates change, if data
Meet communication protocol, then main MCU issues range data from MCU, after being detected to data again from MCU, if data are not inconsistent
Communication protocol then carries out error feedback to main MCU from MCU, and main MCU simultaneously carries out error feedback to PC, to be used to remind change
Data or retransmission from MCU reception amount number of passes evidence, and will appear correct if data fit communication protocol on PC
Then range data can be sent to TLC5615 from MCU by feedback, so that digital-control constant-flow source circuit generates fixed electricity when detecting
Stream, range are arranged shared multiple choices, may diminish to several milliohms to ten ohms, lift the range choosing of wherein 0.2 Ω here
It selects and states its principle:
Amplifier magnification ratio is 11 times, and it is 3.3V that the AD of MSP430, which samples maximum sampled voltage, so VAD=V*11；
So the maximum value 0.3V through the V before amplifying；V=I*R label again, so to make 0.2 Ω of maximum value of R label, as long as
Make the value perseverance 0.3/0.2=1.5A of I, it can achieve the goal；I=VDA/R sampling resistor again, so VDA is needed to export I*R
Sampling resistor=1.5*0.5=0.75V；Inspection information is it is found that the output voltage calculation formula of TLC5615 is VDA=2*VREF*
N/1024, VREF here are 2.5V, 153 are taken by calculating N, as long as then inputting 153 from MCU to TLC5615, so that it may be arranged
Range is 0.2 Ω, and herewith range setting principle is identical for other ranges；At this point, setting completed for range, digital-control constant-flow source output is constant
Electric current I, calibration and resistance value below, which is measured, calculates resistance value also according to above principle；Then equipment enters calibrating die
Formula sends from PC to main MCU and starts calibration command, equally, main MCU and can be detected from MCU to data, until all MCU
Until receiving correct calibration command, so latter two detection test pencil is shorted, and detection switch is pressed, and two test pencils disconnect, and is opened
Shutdown is opened, this will detect that the error resistance between test pencil, and this error resistance is stored into MCU, is made when starting measurement
With.At this point, calibration mode is over, equipment can enter the detection pattern of electronic tag resistance.Next, detection switch is pressed
Under, detection starts, and can enter AD from MCU and sample, the voltage value between electronic tag is converted to digital quantity, until switch disconnects
Afterwards, AD sampling terminates, and institute's measuring resistance value subtracts error resistance when calibration, as true label resistance, to generate 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.It is primary to survey
After amount, until detection switch is pressed again, MCU can just be entered in measurement next time.
