摘　　要：以NXP公司SCI6IS752芯片为核心设计的环境数据采集系统，在控制，管理和调配上实现了对环境数据采集的智能化和集成化。该系统电路直接匹配空气温度、土壤湿度、风速／风向等传感器接口，在核心芯片的调控下，采集到的环境数据经过差分运算、电压跟随、滤波等过程，通过与上层系统相连接的接口上传并进行储存和显示。整个系统自身可外接多种不同传感器，并且能够通过上层系统对其核心芯片进行通信和编程，因此具备较高的扩展性和可塑性，在环境监测，数据采集等实际应用中具有较高的价值。The environmental data acquisition system by taking NXP＇s chip SC16IS752 as the core realized environmental data acquisition of intelligent and integration in the aspects of control, management and allocation. The system circuit directly matches the sensor interfaces of air temperature, soil humidity and wind speed ＆ direction etc, under the regulation and control of the core chip, the collected environmental data is uploaded, stored and displayed through the processes of differential operation, voltage following and filtering, meanwhile via the interface that connects the system with the upper layer system. The whole system itself can connects with the various external sensors and also can realize the communication and programming for its core chip by means of the upper layer system, so the system is of higher expansibility and plasticity and it has higher value in the practical applications of environmental monitoring and data acquisition, and so on.
