Method for controlling operation of cleaning and sweeping trolley, controller and cleaning and sweeping trolley

Abstract

The invention provides a method for controlling operation of a cleaning and sweeping trolley, a controller and the cleaning and sweeping trolley, wherein the method comprises the following steps: the controller receives a current operation mode transmitted by an operation mode select switch and water level information reported by a water level sensor inside a clear water tank; the controller controls whether a clutch between an auxiliary engine of the cleaning and sweeping trolley and a high-pressure water pump is started according to the current operation mode and the water level information, and the controller carries out current operation after detecting a start signal of the auxiliary engine, wherein the high-pressure water pump and the auxiliary engine obtain power from the auxiliary engine under the start state. According to the method, the problems that the high-pressure water pump lastingly operates due to the start of the auxiliary engine, and the service life of the high-pressure water pump is reduced are solved, the practicability of the cleaning and sweeping trolley is enhanced, and the performance is improved.

Description

technical field [0001] The invention relates to the field of construction machinery, and more specifically, to a method for controlling the operation of a cleaning vehicle, a controller and a cleaning vehicle. Background technique [0002] When the cleaning vehicle is cleaning, the water in the clean water tank passes through the high pressure generated by the high-pressure water pump, and the nozzles on the spray bar mechanism form a water curtain to wash the polluted road surface, thoroughly clean the stains, and finally the sewage is recycled by the suction nozzle. So as to achieve the effect of road surface cleaning. [0003] In order to meet the different needs of users, cleaning and sweeping vehicles usually have multiple functions. For example, when the road surface is seriously polluted, especially when there are stains, high-pressure cleaning is required; when the road surface only needs general cleaning, the road-sweeping operation mode is used without high-pressur...
