| 摘要 |
This invention refers to an intrinsically safe remote data monitoring system and a monitoring method for remote data monitoring by using such system. The monitoring system comprises a process control computer that monitors or controls the controlled process, a remote monitoring computer that remotely monitors the process control computer, a signal collecting device physically and non-network connected with the process control computer, for acquiring data 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. The monitoring method comprises following steps: the signal collecting device collecting data from the process control computer in the monitoring system, and then the local monitoring computer (4) transmitting the data signal to the remote monitoring computer for monitoring.
