基站通用数据采集器的设计

Design of universal data acquisition equipment for base stations

数据采集器是基站监控系统内的一种核心设备,用于实现对基站内各种动力设备和环境的监测和报警。设计了一种具有多个输入通道的基站通用数据采集器,每个通道均可采集电压、电流和开关量这3种类型的信号,并且每个输入通道的类型、名称、单位、所接传感器/变送器的转换特性以及报警的上限和下限都可通过软件进行配置。这种通用数据采集器的精度达到了1mV,利用它可以组建从简易到复杂的各种监控系统。

Data collector is a kind of kernel equipment m supervision and control system for base statiom. It can be used to supervise all kinds of power equipments and surroundings to give an alarm. An universal data collector with multi input channels is designed. Every channel can be linked to three kinds of signal such as voltage, current and on-off signal. Every channel＇s type, name, unit, conversion characteristic of sensor and the upper or lower limit can be configured by software. This universal data collector＇s accuracy reaches 1mV. It can be used to constitute simple or complex supervision and control system.
