Automatic compensation control method of snow sweeper roller brush based on pressure feedback

Abstract

The invention provides an automatic compensation control method of a snow sweeper roller brush based on pressure feedback. According to the method, a pressure signal is monitored in real time through a roller brush motor pressure sensor and a hydraulic cylinder pressure sensor, an overall elevating cylinder and a support wheel cylinder are controlled through a PLC (Programmable Logic Controller), the positions of the roller brush and the support wheels are automatically adjusted, and follow-up control on the positions of the roller brush and the support wheels is realized, so that the automatic compensation to abrasion of the roller brush is realized, and the problems that the conventional roller brush device is poor in road situation adaptation capability and poor in snow sweeping effect as the abrasion cannot be compensated in real time are solved. By utilizing the method, an appropriate pump loading pressure is set according to different snow sweeping tasks effectively, different snow sweeping thickness tasks are realized, the real-time adjustment on the distance of the roller brush and the ground in the roller brush working process is realized, and an effective control method is provided for snow sweeping with high requirements in airports and the like.

Description

technical field [0001] The invention belongs to the field of road snow removal, and relates to a snow removal vehicle, in particular to an automatic compensation control method for a roller brush of a snow removal vehicle based on pressure feedback. Background technique [0002] In winter, three-quarters of China's land receives snow. Especially in the north, the snowfall time is long in winter, and the snowfall period in some cold areas lasts for 5 to 6 months. Airports are closed, especially the aviation industry, which is most affected by the snowfall. [0003] Quick snow removal after snowfall has become a major puzzle for major airports in northern cities. In order to solve these problems, researchers have conducted a lot of research on snow removal equipment for roads and airports. The existing methods of snow removal include artificial snow removal, mechanical snow removal and chemical snow removal. The efficiency of artificial snow removal is too low, so it is suit...
