Abstract: In order to realize remote automatic flow measurement,we designed a hydrological cableway flow measurement system based on Web technology.This system can provide hydrological cableway control service by combining Web application Server embedded with WebSocket Server.This system has following features:(1) It can allow client access the application service system and can realize real-time control of the hydrologic cableway equipment simultaneously.Hence,immediacy and stability of the system is improved by reducing the intermediate relay link.(2) It can reduce the coupling between hardware equipment and business functions,which solves the difficulty of upgrading and maintaining hardware equipment.(3) It can solve problems of upgrading and maintaining traditional C/S(Client/Server)system.(4) It can be applied to other platforms or systems that need remote real-time control on hardware devices.
