2. The panel adopts a high -grade aluminum -plastic board with 4mm thick corrosion, strike resistance, pollution resistance, fire prevention, and moisture -proof. ① The complete electric vehicle high -voltage system ② the complete motor control system ③ the management system and display system of complete lithium iron phosphate battery pack);

Students can intuitively control the working principle of the structural schematic diagram of the high -voltage safety protection system of electric vehicles, and to understand and analyze the working principle of the high -voltage safety protection system of electric vehicles.

3. Install a little fire switch, the real lithium iron phosphate battery pack, electric vehicle safety m--ntenance plug module, high -voltage circuit simulation system, safety relay component, leakage protection module and simulation operation switch.

4. The panel part uses a 1.5mm cold plate stamping and forming structure, which is beautiful in shape; the bottom part is welded with steel structure, the surface is treated with spraying process, a self -locking wheel device, and a desktop of about 30cm on the bottom of the teaching plate, which is convenient for placing. Data, light detection instruments, etc.

5. The work of the electric vehicle battery pack is used. The 12V DC power supply of other systems is provided by the DC/DC module. The electric vehicle national standard 220V charging port and charging gun are installed to truly realize the charging operation of the electric vehicle.

6. Real electric vehicle high -voltage safety protection system device, safety relay (including total positive relay, total negative relay, pre -charging relay) can control and work normally through the high -voltage safety system control unit of electric vehicles;

The high-voltage safety system control unit adopts CAN-BUS communication control;

7. Real electric vehicle Hall -style current sensor, the current data stream of the system is truly detected, and the 7 -inch color screen display is transmitted through the BMS control unit CAN bus.

8.BMS control unit 7-inch color screen displays use CAN-BUS communication control to wake up and other signals.

9.BMS control unit 7-inch color screen displays use Can-BUS communication to display real signals such as voltage, current, temperature and other status of lithium iron phosphate battery battery.

10. The high-voltage security system control unit uses CAN-BUS communication to display signal information such as security alarms and "Ready".

1. System summary

The tr--ning device of the automatic fire alarm linkage system is usually used as an independent subsystem of BAS (building equipment management system) in smart buildings. The system is a fire alarm by the parameters of various detectives (smoke detectors and temperature detectors) in various detectives in the fire system, and through relevant signals to achieve fire control control. The system can conduct all kinds of simulated fire and alarm linkage operation demonstration, system settings, linkage programming, line design, networking, line, and setting fault judgment and exclusion. And can monitor the computer center through the fire alarm linkage to monitor the entire smart building fire system, and can conduct flat graph improvement, screen layout, alarm point settings, etc., m--nly consisting of computer, programming software, monitoring software, network adapter, etc.
