i.LON 100 with WebAccess improves safety monitoring of China's Coal Mines.
Government offices monitor safety at coalmines using Echelon's LonWorks technology and Broadwin's WebAccess HMI and SCADA software. October 20, 2004 - San Ramon, California Shanxi province holds the richest coal reserves in China and is a major coal producer with hundreds of small and medium sized mines. Coalmine accidents are a frequent hazard in the province, due to a lack safety monitoring and low risk awareness among miners. The accidents in the coal rich province, led the Shanxi provincial government to implement systems to monitor coalmine safety.
One of the first systems brought on-line utilizes LonWorks control system technology from Echelon and Supervisory Control and Data Acquisition (SCADA) software from Broadwin Technology Inc. Echelon's LonWorks Technology Echelon's LonWorks was selected for the reliability provided by its distributed, multiple-node network architecture. Each node in the LonWorks architecture runs independently of the others; this allows the system to continue to monitor the mine if an explosion or rock fall crushed some of monitoring equipment. Echelon's i.LON100 was selected for its Internet connectivity and the ability to access data remotely.	Figure 1 - Network Drawing of Shanxi coalmine safety monitoring system components
Implementing WebAccess Broadwin Technology's WebAccess HMI & SCADA software provides the Human Machine Interface (HMI) to the i.LON 100 control and monitoring system. WebAccess generates graphical displays of trends, historical and real-time data, alarms and reports that can be viewed in a web browser.
WebAccess allows management and officials to remotely monitor conditions at the mine using an ordinary web browser over the Internet or a dial-up connection. WebAccess was selected over other HMI software for its reputation for reliability and proven interface with the iLON100 at other facilities throughout China. The WebAccess system monitors the ventilation system including fan operation, airflow and toxic gases via the i.LON 100 and the LonPoint field hardware. If fans fail or toxic gases are detected, the system generates alarms. Similar systems are to be installed at all coalmines in the Shanxi Province. By increasing safety at the coalmines, the Shanxi provincial government expects to increase business development in the region.	Figure 2 - WebAccess Graphic Display of Coalmine Ventilation Monitoring
