Method for controlling power-switching stable operation of air-conditioner unit of dual-powered trolley bus

Abstract

The invention discloses a method for controlling power-switching stable operation of an air-conditioner unit of a dual-powered trolley bus. The method comprises the steps: S1, a detection circuit real-timely monitors the voltage of a network cable power supply and the electric quantity of storage batteries and transmits detection values to a main logic control unit; the main logic control unit sends high-level / low-level signals of forced energy-saving and forced shutdown and an air-conditioner unit enters a forced energy-saving status or a forced shutdown status according to each control signal; S2, under the forced energy-saving status, the detection circuit real-timely monitors the voltage of the network cable power supply and the electric quantity of the storage batteries and transmits the detection values to the main logic control unit; the main logic control unit controls the air-conditioner unit to keep the forced energy-saving status or enter the shutdown status or recover normal operation according to the detection value. The air-conditioner unit is operated according to the control signals transmitted by the main logic control unit; when the trolley bus is running by switching the power between a high-voltage overhead line network and a wireless network zone, the stable operation of the air-conditioner unit is maintained and the driving mileage of the electric vehicle is guaranteed sufficiently.

Description

technical field [0001] The invention relates to a control method, in particular to a control method for stable operation across power sources of an air-conditioning unit of a trolleybus with dual power sources. Background technique [0002] Double source trolleybus is a kind of public transportation that uses electricity to drive and does not rely on fixed rails on the road. The electricity it uses is generally obtained through overhead cables and collector poles on the car. On road sections, electricity is supplied by batteries for a short time. In order to ensure the comfort of driving, the dual-drive trolleybus is equipped with an air-conditioning unit. When the vehicle is driving in the high-voltage overhead line network section, the power is sufficient, and the air-conditioning unit can perform high-frequency operation according to the temperature inside the car. When the vehicle is driving in a section without high-voltage overhead power grid, the vehicle is powered b...

Problems solved by technology

In order to ensure the comfort of driving, the dual-drive trolleybus is equipped with an air-conditioning unit. When the vehicle is driving in the high-voltage overhead line network section, the power is sufficient, and the air-conditioning unit can perform high-frequency operation according to the temperature inside the car. When the vehicle is driving in a section without high-voltage overhead power grid, the vehicle is powered by the battery. At this time, the air-conditioning unit still maintains high-speed operation, which will consume a large amount of battery power and cannot guarantee the cruising range of the vehicle.
