Microcomputer control system of electric-wheel truck

Abstract

The invention relates to a microcomputer control system of an electric-wheel truck, comprising a microcomputer control device and a display device; the microcomputer control device comprises a bottom plate and a plurality of plug-in plates which are connected with the bottom plate; a control plate comprises a digital signal processor, a programmable logic device, a plurality of AD converters, a plurality of storages and a communication interface; the AD converters convert analog quantity of the electric-wheel truck into digital quantity; and the digital signal processor respectively controls the programmable logic device, the AD converters, the storages and the communication interface, simultaneously receives the data of the programmable logic device and the AD converters, operates the transmitted data, sends operated results to the display device for display by the RS485 communication interface and correspondingly transmits the data to an output plate and a DA plate for delivering data quantity for output so as to control the electric-wheel truck. The microcomputer control system improves the using performance of the electric-wheel truck, reduces production cost and has the advantages of simple structure and simple and convenient repairing.

Description

technical field [0001] The invention relates to electric wheel vehicles, in particular to a microcomputer control system suitable for 170t electric wheel vehicles. Background technique [0002] At present, more than a dozen domestic units that use electric wheel vehicles are mainly distributed in metallurgy, coal and other industries and large-scale water conservancy projects. The load capacity is mainly about 100 tons. In order to pursue production efficiency, users prefer to use electric wheel vehicles with a larger load capacity. In recent years, with the increase of mining scale and the construction of major water conservancy projects, the proportion of demand for large-tonnage electric wheel vehicles has been increasing. Electric wheel vehicles mainly rely on imports. With the increase of the service life of the vehicle, the condition of the equipment is gradually aging, and the performance of the control panel has declined, resulting in an increase in the failure rate ...

AI Technical Summary

Problems solved by technology

Electric wheel vehicles mainly rely on imports. With the increase of the service life of the vehicle, the condition of the equipment is gradually aging, and the performance of the control panel has declined, resulting in an increase in the failure rate of the vehicle. In addition, the price of the control panel is high, the procurement cycle is long and the repair is difficult. Especially the most core CPU board, its structure is complex, expensive, and cannot be repaired at all in China, and the operating cost is high, which directly restricts the operation rate of the car. Therefore, the localization of the control system of electric wheel vehicles is imminent.

So far, two domestic companies have developed microcomputer control systems for electric wheeled vehicles, but they are only suitable for electric wheeled vehicles with a load of less than 154t.
