| 摘 要： | 为了快速、准确地获取奶牛产奶量数据,避免目前常用的间接测量方法产生的误差,设计了基于质量计量的奶量采集系统。该系统通过在奶罐下安置基于压力传感器的质量称量机,将压力产生的模拟电信号通过A/D转换模块转变为数字电信号,再经分级处理从而获取牛奶质量数据,并直接上传至上位机。上、下位机之间通过CAN总线连接,基于自主协议进行相互通信。经多次测试表明,在5～35kg范围内该系统的测量误差可以控制在6%以下,且具有采集速度快、容错性强的特点。

| 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. |
