Vehicle-mounted terminal of round bander and control system and method

Abstract

The invention discloses a vehicle-mounted terminal of a round bander and a control system and a method. A central processor is used for acquiring parameters such as the rotating speed of a feeding knife roll of the bander, the position of a feeding hole bottom door, the position of a baling connecting rod and the pressure of a baling oil cylinder in real time through a signal input module in real time, and the back pressure of a safety valve is changed through an output control module, so that density regulation of bales is realized; the opening of a feeding hole can be adjusted according to the rotating speed change characteristic of the feeding knife roll by changing the position of the feeding hole bottom door, so that straw blockage is avoided, and logical control of picking, bundling, parking, winding and unloading is realized. The operation state and parameters, geographic position information and the like of the bander can be displayed and stored in real time, and output and remote monitoring can be performed through serial communication and wireless communication. The operation state and parameters of the bander are monitored in real time, so that the overall operation performance, efficiency and reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of baler automatic control, and in particular relates to a vehicle-mounted terminal and control system and method of a round baler baler. Background technique [0002] In the field of baler automatic control technology, picking and baling is an important link to realize the comprehensive utilization of crop straw, and baler is the main machine tool to realize straw baling. According to the shape of the bale, the baler can be divided into a round baler and a square baler. Among them, the round baler mainly includes long belt type, short belt type and steel roller type. [0003] In recent years, my country has developed various forms of round balers by itself, but compared with foreign advanced models, its overall matching power is small, the degree of intelligence is low, and the reliability is poor, especially when harvesting wet, tall and complete rice. When baling stalks and pastures, the problem of materi...

Problems solved by technology

[0004] In order to achieve the above-mentioned purpose, the present invention aims at the problems of low automation, poor reliability and serious blockage problem of the current round baler, and designs a vehicle-mounted terminal and control system and method of the baler. The speed of the feeding knife roller changes, and the opening of the feeding opening is automatically adjusted to improve the feeding performance of the baler. By changing the position of the baler connecting rod, the change process of the diameter of the bale is monitored, and the back pressure of the safety valve can be adjusted. To meet the bundling requirements of materials with different moisture content and different compactness requirements, realize the logic control of picking up, bundling, parking, winding and unloading, with fault alarm, operation status storage, serial port and unlimited communication output functions
