ARM9-based Monitoring System For Aquaculture

The traditional fish farming there is a risk factor, the original work and so on. Therefore, the introduction of automated monitoring technology to the traditional fish farming industry, can promote the development of fish farming, reduce farming risks and improve the economic benefits of farmers.The system consists of monitoring terminal (oxygen sensor ME3-O₂, pH value of the sensor E-201-C, the oxygen temperature sensor DS18B20, information acquisition board, ARM development board) and monitor the host composition. Three sensors connected to the information collection plate, the information acquisition board through the serial port to connect to the ARM development board, ARM development board through the network cable connected to the monitoring host to form a monitoring network.Monitoring of the main terminal to complete the information collection and data processing.First, the collected data transmission between PC and set down the parameters of the pre-threshold comparison to determine whether the data beyond the warning line, and decide whether the police. If not overrun, the data is sent to the ARM development board and in its LCD display, and continues to transfer to the host computer into the SQL database. Based on this function, the paper design and development of information based on ATmega16 acquisition board, and using the ARM S3C2440 based development board.From the application point of view, select the embedded Linux system as the system's software platform, built a cross-compiler development environment. And complete the configuration of Linux kernel and root file system migration created.Monitoring station of the PC machine is mainly is to provide users a friendly interface management software. Its main function is to receive three regular collection and transmission onto the sensor data is written during the post-judgment security, local database, the user can query the current real-time data and historical data. And has user management, parameter settings and other functions on the lower limit.
