The remote monitoring and analysis system of mine safety based on virtual instrument

The remote monitoring system of mine safety based on C/S and B/S mixed mode was developed by using the virtual instrument technology, network technology and database technology. The system consists of sensors,the underground substation, the ground monitoring center remote clients, through internet explorer, the remote client can browse the real-time monitoring data of mine safety, such as gas, wind speed, carbon monoxide, temperature, etc. The storage and access for a large quantity of data in mine safety monitoring was realized by using ADO in LabVIEW. Remote panel technology built-in LabVIEW 8.0 was applied to satisfy the real-time data display of remote monitoring. Web application interface is developed based on ASP technology, while realizes the interaction and data transmission between browser and server.
