Wireless measuring system and method forrotating speed of waterproof agricultural machine crawler driving wheel

Abstract

The invention discloses a wireless measuring system and method for a rotating speed of a waterproof agricultural machine crawler driving wheel. The wireless measuring system comprises a wireless rotating speed measuring device, a waterproof box, and a display device; the wireless rotating speed measuring device is installed in the waterproof box and is in wireless communication with the display device, the wireless rotating speed measuring device comprises a photoelectric encoder, a single chip microcomputer, and a single chip microcomputer wireless transmission module, QI wireless charging module capable of charging a rechargeable lithium battery, and measured data of the photoelectric encoder are transmitted to the display device through the single chip microcomputer wireless transmission module to be displayed; and the wireless measuring method comprises the steps that after data initialization, the frequency of the photoelectric encoder and the rotational direction of the driving wheel are measured, and the measured data is transmitted to the display device through the wireless transmission module through the set communication protocol to be displayed. According to the wirelessmeasuring system and method, the rotating speed of the driving wheel can be measured in a high accuracy mode, data transmission is completed through wireless communication, effective transmission isprovided, the waterproof capability is relatively high, and thus the measuring system is capable of being used for a long time in paddy fields.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery automation, in particular to a waterproof agricultural machinery track drive wheel speed wireless measurement system and a measurement method. Background technique [0002] Agricultural modernization has developed to the stage of intelligence, and the whole process of agricultural intelligent control has been put on the agenda. Fully automatic agricultural engineering technology has been widely used. The emergence of unmanned agricultural machinery and automatic operating tools has greatly reduced the labor intensity of farmers' farming. Among them, the field operations such as tillage, sowing, fertilization, irrigation, spraying and weeding are digitally controlled. The resource utilization of agricultural inputs is precise and the efficiency is maximized. Among them, the automatic navigation technology of agricultural machinery is one of the key technologies. High-quality agricul...

Problems solved by technology

[0004] In order to better complete the navigation control of crawler agricultural machinery, it is necessary to accurately measure the speed of the left and right crawlers. The traditional Hall sensor speed measuring device has low precision and cannot meet the demand.

Since the paddy field is wet and there are many residues when the paddy field is harvested, if the information is transmitted by wire, the passability will be reduced. At the same time, the waterproof performance of the measuring device must be good. Therefore, a track wheel speed measurement system with wireless and waterproof functions is designed. The navigation control of crawler agricultural machinery is of great significance to agricultural production
