Road sweeping and cleaning car electric control system based on touch screen control

Abstract

The invention discloses a road sweeping and cleaning car electric control system based on touch screen control. The road sweeping and cleaning car electric control system based on the touch screen control comprises a programmable logic controller (PLC) (1) and a peripheral input and output circuit of the PLC (1), and is characterized in that the PLC (1) is connected with an operation panel (2) in cab through an RS485 or RS422 or controller area network (CAN) bus, and a touch screen controller (21) is arranged in the operation panel (2). The road sweeping and cleaning car electric control system based on the touch screen control has the advantages that the structure of the circuit is simple, the wiring difficulty is lowered, an original key switch is replaced by a touch screen, the integration degree is largely improved, the visibility and the operability are largely strengthened, the work state indication can be provided in real time, and the failure of the equipment can be resolved conveniently.

Description

technical field [0001] The invention relates to an automatic control technology on a special vehicle, in particular to an electrical control system of a cleaning and sweeping vehicle based on touch screen control. Background technique [0002] Road cleaning and sweeping vehicle is a special vehicle for road cleaning that integrates high-pressure floor washing and road sweeping. The vehicle has the advantages of a road sweeper and a cleaning vehicle, and realizes no dust in daily operations, no water accumulation on the road surface, no dust retention, and can adapt to the cleaning requirements of different polluted road surfaces. [0003] With the development of the economy, the pace of urban construction is constantly accelerating, and road sweepers have been widely used for quick cleaning and washing of roads in municipal, sanitation roads, squares and expressways. [0004] At present, most of the control devices of cleaning and sweeping vehicles adopt the mechanical cont...

Problems solved by technology

And when working, according to different road conditions and requirements, there are various operation modes such as left sweep, right sweep, left and right full sweep, left wash, right wash, left and right full wash, flushing, etc. There are many actions and the control principle is more complicated.

[0007] Therefore, using conventional key switches and PLC program controllers to realize control still has difficulties such as complicated wiring, low operation visualization, and difficult troubleshooting.
