信息系统管理

• This system use the floater style sensor , mechanical encoder to get water - level signal , and use the at89c51 single chip system to transform the signal into water - level data , use modem through pstn to transmit data for a long - distance , and designed a information management software system hi the irrigation works bureau information center for communication and data management . the structure of the system was discussed in the thesis
  该系统使用浮子式传感器、机械式编码器获取水位信号，利用at89c51单片机系统采集水位数据(简称：下位机系统) ，采用调制解调器、通过公共电话网( pstn )远程传输数据，并在泰兴市水务局信息中心通过主控计算机(简称：上位机)进行通信及信息系统管理。
