[0002] With the popularity of electric vehicles and the construction of charging facilities, the sales of electric vehicles are increasing year by year. However, there are certain safety hazards in the process of charging electric vehicles, and the most important problem is the fire risk caused by battery overheating. At present, a modular intelligent charging cabinet system based on the concept of "separation of vehicle and electricity" has also appeared, which realizes efficient centralized charging of electric bicycle batteries through independent battery charging units.

[0003] The existing charging shed generally has a fire extinguishing system, but there are certain defects:

[0006] 3. There is no protective device for the battery being charged alone.

[0007] Therefore, a charging pile car shed safety prevention and control system is proposed. SUMMARY

[0011] Preferably, the measuring device uses temperature sensor, smoke sensor or infrared thermal imager.

[0012] Preferably, the charging socket is integrated with current or voltage sensor inside.

[0013] Preferably, the fire extinguisher uses dry ice fire extinguisher or dry powder fire extinguisher.

[0014] Preferably, the clamping mechanical arm adopts a six-axis collaborative mechanical arm, a high-temperature-resistant clamp and a pressure feedback module.

[0015] Preferably, the control box is internally integrated with a linkage controller and an edge computing gateway.

[0016] The edge computing gateway integrates Modbus RTU and CANopen double protocol stacks, and supports heterogeneous communication fusion of sensor data and actuator instructions.

[0017] Preferably, the linkage controller drives the mechanical arm evacuation device, starts the fire extinguishing device and performs staged power-off.

[0018] Compared with the prior art, the utility model has the beneficial effects that: the double criterion of sensor threshold value triggering and AI vision secondary confirmation reduces the false alarm rate from 15% of the traditional scheme to below 2%, mechanical evacuation is prior to fire extinguishing start, avoids freezing of mechanical parts by fire extinguishing agent, delays time is optimized through fluid mechanics simulation, and through LSTM prediction of environmental parameter baseline, the threshold value adapts to long-term interference such as diurnal temperature difference and seasonal change.
