Problems solved by technology

However, the current level of sweeping vehicles is relatively low, and some sweeping vehicles still use basic relay switch solenoid valves to complete some basic hydraulic control. The operation control cannot be completed through a single-chip microcomputer, and the degree of intelligence is too low to complete the cleaning tasks smoothly and intelligently.

Abstract

The invention discloses a single chip microcomputer control system. The system comprises a power supply module, a watchdog circuit, a crystal oscillator, a single chip microcomputer, a first expansion circuit chip, an input isolated optical coupler, a switch value input circuit, a second expansion circuit chip, an output buffer isolating amplifier circuit, an output driving solenoid valve, a stepping motor driving circuit, a stepping motor, a third expansion circuit chip, an isolation circuit, a vehicle speed sensor and a disc brush rotating shaft sensor. Cost is low. Through cooperating with a peripheral circuit, complex program control can be realized. A control task of a hydraulic system can be well completed and digital intelligent control to a motor sweeper is realized. Through re-compiling a program, under the condition that a hardware structure is not changed, a control strategy of the system can be changed to adapt to different control schemes.

Description

technical field [0001] The invention relates to the field of sweeping vehicles, in particular to a single-chip microcomputer control system for sweeping vehicles. Background technique [0002] As one of the sanitation equipment, the sweeper is a new type of efficient cleaning equipment that integrates road cleaning, garbage recycling and transportation. It is widely used in arterial roads, municipal and airport roads, urban residential areas, parks and other road cleaning. However, the current level of sweeping vehicles is relatively low, and some sweeping vehicles still use basic relay switch solenoid valves to complete some basic hydraulic control. The operation control cannot be completed through a single-chip microcomputer, and the degree of intelligence is too low to complete the cleaning tasks smoothly and intelligently. . Contents of the invention [0003] The purpose of the present invention is to solve the problems mentioned in the background technology section a...
