奶牛产奶量测量系统设计
Design of milk yield measurement system
摘要
Abstract
In order to collect milk yield data rapidly and accurately, avoid the measurement error caused by commonly indirect measurement methods used at present, a milk yield collection system based on mass measurement method was designed. A mass measurement device based on pressure sensor was placed under the milk container, and the measuring signal were transformed to digital signal by A/D module to obtain the milk yield data and upload them to host computer. In the system, CAN bus was used to connect the lower computer to host computer with self-developed communication protocol The test results show that the system has the features such as rapid collection, strong fault-tolerance, and the measurement error can be controlled less than 6% in the range from 5 kg to 35 kg.关键词
