Through the operation training of this device, students can assess the comprehensive ability of the installation, adjustment and maintenance of intelligent elevators, such as the installation of elevator call box, the installation of hoistway information system, the adjustment of leveling switch detection position, the adjustment of door machine mechanism, the adjustment of electrical control cabinet Device installation, wiring, inverter parameter setting, PLC programming and debugging, elevator group control function debugging, elevator troubleshooting, operation and maintenance, etc., in addition to satisfying professional training and teaching, it can also carry out skill assessment and professional skills competition.

Boiler heating program control protection system 1. The boiler heating liner is equipped with a water level and liquid level protection device, and the control system can only control the heating after the water level reaches the specified height. 2. The power control switch of the electric heating tube adopts a key switch, which is easy to manage. Power protection measures 1. There is a current leakage protector. 2. The two-phase power supply has a fuse to prevent disconnection. Power start-stop control mode; Use the start-stop button to control the contactor to control the start and stop of the power supply. Leakage protection device and safety and safety commitment; Reliable protection functions of various power supplies and various instruments

The system integrates programmable controller (S7-1200), Botu software, and simulation control experiment board. In order to combine teaching requirements, a variety of domestic textbooks were used in the design process, and 10 groups of the most typical experiments were selected.

The portable solar power experiment box is a solar photovoltaic power supply system, through which it can provide a practical teaching, experiment and demonstration platform for the working principle of solar cells, controllers and sine wave inverters.

The system adopts a vertical structure, the panel adopts a standard mesh plate, and the experimental modules are completely exposed. It has a strong sense of presence and can quickly allow learners to enter the learning role. The completely closed-loop control method allows users to operate more humanely.

Convenient experiment: The workbench is equipped with four casters to facilitate the overall movement of the equipment. Since the angle and height of the panel are designed according to ergonomics, it can be conveniently used in experiments. The groove interval of the panel is 25mm, and various components can be plugged and unplugged easily.

The control system uses modular , which consists of a variety of actuators and other components, user can combine the modules according to an action or flexible combination, installation and debugging. Protection: chassis mechanical rotation angle limit protection; up and down mechanical limit protection; mechanical arm limit protection.

The system uses modern computer simulation information technology to solve the problem of the disconnection between the previous professional training theory, experiment, practice and practical application through the three training levels of operation, simulation and simulation.

Defensive function. Chassis mechanical rotation angle limit protection function; Rise and fall mechanical limit protection function; Deploy configuration software and provide examples of application guidance and engineering application. The pneumatic part is divided into cylinder, air supply processor, air pump, solenoid valve and pneumatic gripper. It can rapidly grab and drop things.
