摘要
介绍由MSP430F133单片机为核心的闸门开度仪,它具有测量值和设定值液晶显示,4mA^20mA标准模拟量输出,4个继电器超限动作,测量值通过GSM短消息发送给管理者的功能,从而实现了对闸门开度远程无线监测的目的。
The gate opening instrument cored with MSP430F133 chip is introduced in this paper. It has the following functions： LCD display of the measured value and the setting value, 4mA -20mA standard analog output, four relay-overruns and delivering the measured value to monitor through GSM message. Thereby, gate opening can be monitored remotely and wirelessly.
