Temperature sensor, for regulating the power adjustment apparatus of microwave heating equipment power, described microcomputer, temperature pass
Sensor, power adjustment apparatus and microwave heating equipment are all connected with PLC.Microcomputer need to be equipped with
STEP-Micro/WINV4.0 programming software and pro digital image processing software, microcomputer to possess process in real time
Ability.PC/PPI many main websites cable RS-232 is connected to the communication port COM1 of computer.Figure
As collecting unit can use the digital camera of Canon HSF S21, can be installed in microwave heating equipment
The heart so that it is there is the image effect of high definition, it is simple to gather and check.PLC can be Siemens S7-200PLC,
And PLC includes CPU224, Analog input mModule and analog output module.It is preferred that analog quantity is defeated
Entering module is EM231 module (4 tunnel input), and analog output module is EM232 module (2 tunnel output).
Wherein, CPU224, EM231 module and EM232 module are powered by 24V power supply.Temperature sensor is used
In the temperature of collection microwave heating equipment, and being passed along PLC analysis, PLC is by analysis result and presets
Definite value contrasts, and then judges that controlling power adjustment apparatus controls whether microwave heating equipment heats；Specifically,
When the temperature of detection is less than pre-set value, PLC controls microwave heating equipment by power adjustment apparatus and heats.
Preferably, microcomputer also includes edge detection unit and the stress and strain model dividing the image outline after detection
Unit.Specifically, what digital camera was real-time carries out image acquisition to bituminous paving, and the image of collection is incoming to be taken
Having the microcomputer of digital imaging processing software, microcomputer carries out rim detection by Marr edge detection algorithm to image,
Microcomputer carries out stress and strain model to the image outline after detection again.Owing to picture noise has certain shadow to rim detection
