This training device is mainly composed of various types of industrial sensors, pneumatic controls, hydraulic controls, electrical switches, PLC programmable logic controllers, man-machine interfaces, etc., to cultivate students' corresponding knowledge and skills.
(1) The training platform uses aluminum alloy substrates to build a training platform with a stable structure. Each actuator module is placed on the base plate, which is easy to use and not easy to damage. (2) The training device is equipped with an electrical control cabinet, the power supply of the system is led out through a safety plug, and the wiring of the training device is connected through a terminal, which is safe and reliable. (3) The organic integration of mechanical technology (including pneumatic technology), sensor technology, PLC control and communication network technology reflects the characteristics of the modern manufacturing production process. The overall structure adopts open and disassembly type, which can easily replace the modules. The content of the modules is determined according to the principles of productive functions and integrated learning functions, so that the required modules can be easily selected during teaching or competition.
The power input terminal is placed in the power distribution area on the training platform, led out through the plug, and the total power supply of the system is controlled by the leakage circuit breaker.
Compressed air is supplied to all pneumatic components of the device through the pressure reducing valve. The outlet end of the pressure reducing valve is controlled by a valve, which is convenient for debugging. When the system is running, adjust the pressure value of the pressure reducing valve to 0.6MPa (pull up the pressure adjusting knob, turn the knob to adjust the pressure value to 0.6MPa, after the adjustment is completed, press the knob down to lock the knob and prevent it from rotating) . 1- Pressure adjustment knob 2- Air outlet 3- Air inlet 4- Air outlet switch 5- Pressure gauge

working principle The intelligent circuit board adopts advanced integrated circuit and SMT technology to concentrate the conversion circuit and the processing circuit on a circuit board. The microprocessor of the transmitter controls the work of AD and D/A conversion modules, and also completes digital communication and self-diagnosis functions. When working, the microprocessor controls the A/D conversion module to sample and convert the analog signal from the sensitive element and convert it into a digital signal. The microprocessor processes digital signals, including signal linearization, temperature compensation, engineering unit conversion, etc. The microprocessor can also complete the characterization, range, damping time and other functions of the sensor. E2PROM stores all configuration and fine-tuning parameters. Since the memory is non-volatile, the stored parameters will not be lost after power off.
