Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] see figure 1 , the present invention provides a technical solution: a method for controlling the constant power of the upper equipment of a pure electric compression garbage truck, comprising the following steps:

[0025] Step S100, judge which actuator of the bodywork equipment is acting according to the state signal of the multi-way valve. If it is the action of garbage bin rising, scraper scraping or sliding plate rising, enter the constant power working mode; if it is other actions, enter the constant power working mode. Speed ​​operation mode, enter step S102, set the motor speed n as 1800rpm;

[0026] Step S101, setting the initial target speed of the motor to 1800rpm;

[0027] Step S103, measuring and storing the outlet pressure of...

Abstract

The invention provides a constant-power control method for equipment mounted on a pure electric compression type garbage truck. The method comprises performing working mode selection through a state signal of a multi-way valve, if a garbage can rises, a scraper plate performs scraping joining or a slide plate performs rising motion, entering a constant-power working mode; and if other motions are performed, entering a constant-rotating-speed operation mode. In the constant-power working mode, an outlet pressure of a hydraulic pump is detected. If the outlet pressure exceeds a preset pressure of an overflow valve, a motor rotating speed is set to a least allowed rotating speed, and otherwise, a motor target rotating speed is calculated according to a pressure-rotating-speed constant-power relationship. If the calculated rotating speed exceeds a maximal allowed rotating speed, the motor rotating speed is restricted to the maximal allowed rotating speed. If the calculated rotating speed does not exceed the maximal allowed rotating speed, the motor is operated according to the calculated rotating speed. According to the constant-power control method, not only can operation efficiency of the equipment mounted on the pure electric compression type garbage truck be improved, but also overflow loss of the hydraulic pump can be reduced, thereby prolonging duration mileage of an electric vehicle.

Description

technical field [0001] The invention relates to a constant power control method for top-loading equipment of a pure electric compression garbage truck. Background technique [0002] With the continuous strengthening of people's awareness of environmental protection, local governments have increasingly higher requirements for emissions, and pure electric vehicles have the advantages of zero emission, low noise and high efficiency, so they are more and more valued by the state and enterprises. Various pure electric vehicles Cars have been introduced to the market in large numbers. At present, the application of electric vehicles has gradually penetrated into the fields of special vehicles such as sanitation, postal services, and logistics. [0003] The compressed garbage truck is a special vehicle for urban sanitation that efficiently collects and transfers garbage. During the garbage collection and transfer process, it can avoid secondary pollution caused by spilling along t...
