基于PDA和FSM的肉牛养殖可追溯信息采集与传输方法

为提高肉牛养殖信息采集与传输的自动化程度准确性，该文提出了基于个人数字助理（PDA）和有限状态机 （FSM）的肉牛养殖可追溯信息采集与传输方法。利用PDA采集肉牛的日常养殖信息；在信息传到PC的过程中，通过利用有限状态机原理，以事件驱动的方式实现了PDA与PC之间的串口信息传输。重点研究了串口传输过程中有限状态机的建模，该方法改变了肉牛养殖信息传统、人工的采集与传输的方式，实现了养殖场信息的快速、准确的采集与传输。

Method of traceability information acquisition and transmission for beef cattle sector based on PDA and FSM

For improving the efficiency and accuracy of information acquisition in beef cattle sector, a new approach to information acquiring and transmitting was put forward. It was the personal digital assistant (PDA) which was used to acquire the routine breeding information. And, based on finite state machine (FSM), the transmission of serial information transmission between PDA and PC was realized by event driven way. The modeling of finite state machine was emphatically studied. Changing the mode of information transmitting and acquiring in the beef cattle breeding, the transmission and acquisition was more speedy, effective and accurate and the efficiency of livestock farms management was improved.
