Wireless Cluster Control System for Roll-machine

Abstract. The wireless remote monitoring plays an important role in the process of agricultural information. After investigating current situation of greenhouse roll-machine, this paper deeply discussed problems about greenhouse temperature real-time monitoring, roll-machine switch control and cluster management. Based on these problems, this paper developed a wireless cluster control system for roll-machine, including master control box, slave control box and network monitoring platform. The network monitoring platform adopts B/S mode. The temperature of greenhouse can be obtained through slave control box installed in greenhouse. The temperature data will be send to master control box via digital radio in specific format. Then the master control box will transmit these data to network monitoring platform via GPRS. The network monitoring platform adopts B/S mode. the network monitoring platform will analyze data and display them in curve. In addition, the employee or users can send control command to slave control box so that they can modify parameter of roll-machine controlling. By using this system, roll-machine can be run automatically according to temperature inside greenhouse. The entire system effectively improves the level of intelligence and automation in roll-machine controlling and enhances management of greenhouse.
