Electrical control system for small multifunctional environmental sanitation electric vehicle

Abstract

The invention discloses an electrical control system for a small multifunctional environmental sanitation electric vehicle. The electrical control system comprises a system master controller, a left rear motor control circuit, a left rear motor power driver, a left rear motor inverter circuit, a left rear hub motor, a left rear motor zero cross detection circuit, a left rear motor overcurrent protection circuit, a right rear motor control circuit, a right rear motor power driver, a right rear motor inverter circuit, a right rear hub motor, a right rear motor zero cross detection circuit, a right rear motor overcurrent protection circuit, a signal acquisition module, a storage battery, a charging interface, a CAN communication interface, a disc sweeping motor and a spraying water pump. The electrical control system has the beneficial effects that a mechanical transmission mechanism of the vehicle is greatly simplified, the speed adjusting range is wide, the speed adjusting performance is smooth, the starting torque is large, control is easy, operation is reliable, efficiency is high, maintenance is free, the service life is long, the noise generated in the operation process is extremely low, and the system is suitable for working in a public place.

Description

technical field [0001] The invention relates to the field of electrical control systems of electric vehicles, in particular to a small-sized multi-functional environmental sanitation electric vehicle electrical control system. Background technique [0002] With the acceleration of my country's urbanization process, a series of urban environmental sanitation problems will inevitably be brought about in the process of its development. Nowadays, labor costs continue to increase. Using manpower for urban environmental maintenance and cleaning is not only inefficient, but also increases government financial expenditures. At present, the domestic sanitation machinery market demand is increasingly strong, the market prospect is huge, and the supply of sanitation machinery is in short supply, especially the small sanitation electric vehicles that can meet the cleaning needs of narrow roads, venues, waiting (aircraft) halls, shopping malls and large buildings. There is a huge vacancy...

AI Technical Summary

Problems solved by technology

Traditional sanitation electric vehicles use ordinary motors as the driving motors of the vehicles. Vehicles using this type of driving motor generally have a complicated mechanical transmission structure. The overall shape and structure of sanitation electric vehicles are large, which is not suitable for working on narrow roads and public places with dense crowds. Inside
