The wiring diagram of PLC control system of the present utility model, as shown in figure 12, by the upper upper limit of hoisting mechanism, upper limit, operation, fault and the first code device signal, is respectively connected in these six input points of I0.0～I0.5 of PLC；By the second code device signal of wiper mechanism, access in I0.6, I0.7 the two input point of PLC, the descaling bath of wiper mechanism is put in place, rinsing bowl puts in place, run and fault-signal, be respectively connected in these four input points of I1.1～I1.4 of PLC；Q0.0～the Q0.2 these three output point of PLC is coupled with the rising of hoisting mechanism by auxiliary reclay, is declined and stop contact；Q0.4 and the Q0.5 the two output point of PLC is coupled with the startup of wiper mechanism by auxiliary reclay and stops contact；The output signal of fiber amplifier is accessed first input point of the Analog input mModule of PLC.
The program flow diagram of PLC control system of the present utility model, as shown in Figure 13, Figure 14.
PLC program starts:
PLC carries out system initialization: the first encoder and the second code device signal reset, and fibre-optical probe arrives upper limit, and descaling bath and the rinsing bowl of wiper mechanism all exit.
The Q0.1 output of PLC, controls hoisting mechanism and drives fibre-optical probe to decline.
If the output signal bust of fiber amplifier 50%～80%, then the Q0.2 output of PLC, controlling hoisting mechanism and shut down, fibre-optical probe stops declining；Otherwise hoisting mechanism drives fibre-optical probe to continue to decline.
The judgement of fiber amplifier output signal bust:
The output signal of PLC Real-time Collection fiber amplifier, ifThen think the output signal bust 50%～80% of fiber amplifier.

The Q0.0 output of PLC, controls hoisting mechanism and drives fibre-optical probe to rise, until it reaches upper limit, and now the I0.1 of PLC receives upper limit signal, and the Q0.2 output of PLC controls hoisting mechanism and shuts down.
The Q0.4 output of PLC, controls wiper mechanism and starts, and descaling bath enters position, and now the I1.1 of PLC receives descaling bath and puts in place signal, and the Q0.5 output of PLC controls wiper mechanism and shuts down.
The Q0.1 output of PLC, controls hoisting mechanism and drives fibre-optical probe to drop to descaling bath, and now the Q0.2 output of PLC, controls hoisting mechanism and shut down.
After soaking 5～10min, the Q0.0 output of PLC, control hoisting mechanism and drive fibre-optical probe to rise, until it reaches upper limit；Now, the 10.1 of PLC receive upper limit signal, the Q0.2 output of PLC, control hoisting mechanism and shut down.
The Q0.4 output of PLC, controls wiper mechanism and starts, and descaling bath exits, and rinsing bowl enters position, and now the I1.2 of PLC receives rinsing bowl and puts in place signal, and the Q0.5 output of PLC controls wiper mechanism and shuts down.
The Q0.1 output of PLC, controls hoisting mechanism and drives fibre-optical probe to drop to rinsing bowl, and now the Q0.2 output of PLC, controls hoisting mechanism and shut down.
After soaking 5～10min, the Q0.0 output of PLC, control hoisting mechanism and drive fibre-optical probe to rise, until it reaches upper limit；Now, the I0.1 of PLC receives upper limit signal, the Q0.2 output of PLC, controls hoisting mechanism and shuts down.
The Q0.4 output of PLC, controls wiper mechanism and starts, and rinsing bowl exits, the Q0.5 output of PLC, controls wiper mechanism and shuts down.
Single detection process terminates.
The interval time of detection is 20～30 minutes every time, and interval time is set by the intervalometer within PLC.Such as faulty appearance during detection, as hoisting mechanism fault I0.3 receives signal, wiper mechanism fault I1.4 receives signal, then PLC control all devices is shut down until fault clearance, and after fault clearance, the step before system is back to fault continues to run with.
During whole, industrial computer is connected with PLC control system by EPA.Host computer monitoring software uses WINCC, is monitored detection process and operates, and can check the trend curve of process data, filing data, and can form form through printer printout.Host computer programming software uses SIEMENS Micro/Win to be programmed PLC.
