AN INTRINSICALLY SAFE REMOTE DATA MONITORING SYSTEM AND MONITORING METHOD THEREOF

摘要

This invention refers to an intrinsically safe remote data monitoring systemand a monitoring method for remote data monitoring by using such system.The monitoring system comprises a process control computer that monitors orcontrols the controlled process, a remote monitoring computer that remotelymonitors the process control computer, a signal collecting device physicallyand non-network connected with the process control computer, for acquiringdata from the process control computer, a local monitoring computer (4)connected with the signal collecting device. The local monitoring computer (4)is also connected with the remote monitoring computer through network. Themonitoring method comprises following steps: the signal collecting devicecollecting data from the process control computer in the monitoring system,and then the local monitoring computer (4) transmitting the data signal to theremote monitoring computer for monitoring.
