Abstract

The invention relates to an intelligent interface adapter of an agricultural machinery equipment sensor. The adapter can be used realize intercommunication among different buses in modern agricultural machinery, and provide basis for intelligent condition information collection for the agricultural machinery. The intelligent interface adapter comprises microcontroller, a data collection part, a data conversion module part, a data selector and processing part and a data output part, and is structurally characterized in that the data collection part comprises a CAN bus, an RS232 bus and an RS485 bus, a CAN / RS-485 module in the data conversion module completes conversion between the CAN bus and RS-485, an RS-232 / RS-485 module complete conversion between RS232 and RS485, a data selector is connected with the microcontroller, a button, an indicating lamp, a liquid crystal display and an RS485 output module are arranged outside the microcontroller, and converted data is output and connected to the data selector and processing part.

Description

technical field [0001] The invention belongs to the field of information agriculture, in particular to an intelligent interface adapter for sensors of agricultural machinery equipment. Background technique [0002] Now that we have entered a comprehensive information society, the rapid development of information agriculture has opened up a broad space for the application of sensors in agriculture. In the seedling raising, production, harvesting, storage and circulation of various crops, various sensors are widely used, so that the research on intelligent sensor interfaces has been paid attention to. [0003] Different types of fieldbuses are very different in terms of function, performance and price, and each has its own characteristic application field. As far as the present is concerned, there is no fieldbus that can fully apply to all application fields, and the coexistence of multiple fieldbuses will exist for a long time. In order to solve the problem of parallel tran...
