基于μC/OS-Ⅱ嵌入式畜禽环境数据采集系统设计

Embedded data acquisition system of poultry environment based on μC/OS-Ⅱ

文章介绍了基于μC/OS-Ⅱ的嵌入式畜禽环境数据采集系统。它采用STC89C516RD+作为控制器,运用Modbus通讯协议,解决数据采集干扰强、采集系统通信速率低、信息标准不统一等问题,实现主站与从站间的通信。本系统能够实现对畜禽环境的数据采集,系统独立性强,可移植性好,实时性得到了明显提高。

Based on μC/OS-Ⅱ, the embedded data acquisition system was introduced. This system used STC 89C516RD＋ as controller and applied Modbus protocol to solve problems including strong interference, low-rate communication and non-uniform information standard, and therefore realize the communication between main station and substation. The system can acquire poultry environment data, has strong independence and good transplant characteristics, which obviously improve the real-time performance.
