Wireless Control System for Plug Seedlings Environment Based on GPRS

In order to realize remote monitoring and control for the environment of plug seeding, the environment control system based on GPRS was developed. The systems includes environment sensors, GPRS remote terminal unit (RTU), control unit and WEB server. Through the GPRS network to transmission the environment parameters, and upload data via the Internet to the web server. According the environment parameters, the server get the optimal control scheme based on model. Then transmit the control scheme to the remote terminal unit (RTU) through the GPRS network. The RTU get the control scheme, the control unit send the control signal to the control equipment. This system can achieve real-time control of environment parameters for plug seedling.

Enhance Efficiency

Remote Terminal Unit (RTU) is a standalone data acquisition and control unit which monitors and controls an equipment at a remote location from the central station that utilizes Distribution Automation System (DAS). The RTU acquires information such as measured values, signal, meter readings and it transmits command or instruction, sets points, controls variables and monitors function time. In the present Distribution Automation System (DAS), the distribution field of automation allows the utilities to implement a flexible control of distribution system to enhance efficiency, reliability, and quality of electric service. The implementation of distribution automation system is highlighted based on two factors; benefit and area of distribution automation system implementation. The hardware design uses PIC16F877A microcontroller to control all the functions of RTU. The types of fault detected are undervoltage and overcurrent. The design consists of MPLAB software development using C programming and hardware assembly. RTU is also designed to communicate with the Supervisory Control and Data Acquisition (SCADA) system and resulting in RTU’s ability to detect undervoltage and overcurrent fault.
