As the accelerated development of the existing mobile communications and Internet integration, high-speed mobile access and Internet Protocol-based service become mature for different kinds of applications, which provide a great convenience for the remote wireless monitoring, mobile data transmission and so on. In this paper, an environmental monitoring data transmission system based on 3G networks is designed to transmit environmental data which is collected through sensors to server-side. The data transmission system is functioning with remote data transmission, and monitoring data reviewing at remote terminal any time. Scientific monitoring data can accurately, timely and comprehensively reflect of the various environmental parameters on-site detection status. The system components of environment monitoring platform based on virtual instrument is introduced firstly. Then, the network transmission system scheme based on Socket communication is proposed. Finally, the data transmission between LabVIEW application of monitoring terminal and PHP application of server-side through Socket interface is achieved. This system transmits well, and queries conveniently. It is safe and timely while being applied in environmental monitoring data transmission.
