摘要
介绍了一种以高增益弱激发电路和振弦式传感器为数据采集模块,以单片机为核心的煤矿坑口自动称重系统。在煤矿坑口安装自动称重系统,使斗车在驶过坑口称重系统时毫不停歇,由称重系统的数据采集部分将车次、每车重量等数据采集后数字化,通过RS-232串行通信,把数据传给PC机,将煤炭的总量进行汇总、打印等。
The paper introduces a kind of automatic weighting system applied at the coalmine pit, which is stimulated by the high-vain and weakexcitation circuit with single-chip processor serving as the core, and collect data by vibrating wire sensor. Passing the system in coalmine pit, the trolley need not stop, the data such as the number and weight of the trolley are collected by the data collecting unit of the system, then transmitted to computer, finally, the total coal amount is concluded and printed.【 Descriptors】 Vibrating wire sensor Dynamic weighting Mathematical mode
