Description

Tractor data recording system and method Technical Field The invention relates to the technical field of agricultural machine data, in particular to a tractor data recording system and method. Background The tractor is the core of modern agriculture, greatly improves the operating efficiency, and is especially indispensable in large-area large-scale mechanized farming. The conventional tractor has the problems of low cultivation efficiency, high maintenance cost and high difficulty, the tractor data recording system records the operation condition by cultivating and analyzing the operation data of the tractor, so that the operation efficiency is improved, and meanwhile, the recording system monitors the state of the tractor in real time, prompts and guides the failure possibly in time, reduces the equipment failure rate and the maintenance cost, enables maintenance personnel and users to know the operation condition of the tractor in the fastest mode, and ensures the normal operation of the tractor. Currently, tractor data recording systems exist on the market that are largely divided into two categories. One type is a factory-matched system provided by foreign well-known tractor manufacturers for their particular make or model, which is typically integrated deep into the tractor's navigation or auxiliary farming module. The other type is simple data recording function of the domestic part of agricultural machinery products, and the functions are relatively single. Existing data recording systems have significant limitations. Firstly, the data record and display content of the system are usually solidified when leaving the factory, and a user cannot customize data items required to be collected or mainly displayed according to actual monitoring requirements, so that the flexibility is poor. And secondly, because protocols of all manufacturers are not uniform and data formats among different systems are not compatible with each other, maintenance personnel are difficult to compare and analyze data of various tractors by utilizing a uniform tool, and the complexity and cost of operation and maintenance are increased. Therefore, developing a universal tractor data recording system that is compatible with protocols, flexible in configuration, and widely applicable has become a technical problem to be solved in the art.
