摘要
本文设计的控制器具有多种功能。首先它可以作为无线调制解调器连接模拟电台和具有485通信接口的设备。其次它具有1路模拟量输入和2路开关量输入。并且它用拨码开关设置地址,方便应用。它还可以在线编程,容易实现多种功能。这样的功能配置使远程监控系统成本低且组建容易。本文说明各功能的实现方法。
The controller designed in this article has multiple functions. First, it can be wareless MODEM connecting analog radio and equipments that have 485 communication interface. The second, it has 1 analog input and 2 digital inputs. It uses a group of switches form the address, so it is convenient to use it. It can be programmed on line,realizing multiple functions easily. Such function configure make the construction of remote supervision system cheap and easy.
