Automatic double-circuit power supply controlling system for ventilating fan of air-conditioned bus

Abstract

The invention discloses an automatic selecting and controlling system for power supply modes of a ventilating fan of an air-conditioned bus. The automatic selecting and controlling system comprises a PID (proportional-integral-derivative) controller, a solar energy power supply module and a conventional power supply module, wherein the conventional power supply module comprises a vehicle-mounted motor and a storage battery, the solar energy power supply module comprises a solar cell panel, a piezoresistor, a capacitor, a rectifier diode, a storage battery and a relay, the controller is used for measuring terminal voltage of the storage battery of the solar energy power supply module, controlling working conditions of the solar energy power supply module and the conventional power supply module via triodes, and controlling working conditions of different LED lamp displaying systems. By the aid of the automatic selecting and controlling system, the power supply modes of the fan can be automatically switched, and the automatic selecting and controlling system is environmental-friendly and energy-saving, and can be utilized in various air-conditioned buses.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a design scheme for automatic control of the power supply of a ventilating fan of an air-conditioned bus with solar energy as the main power supply and ordinary power supply as the supplement. Background technique [0002] In recent years, in order to solve the problem of increasing urban population and increasingly congested urban roads, various cities have invested a lot of money in developing their own public transportation, especially ordinary ground buses. While continuously expanding bus lines and increasing the number of buses, it is also constantly improving the bus ride environment and ride comfort. For example, providing ventilation fans for air-conditioned buses and improving the air quality inside the bus are among them. a measure of. At present, the vast majority of air-conditioned bus ventilation fans are powered by on-board generators or batteries, and the energy...
