Record and Analysis Device for Control Signal and Communication Signal of the Instrumentation Control System for Water Treatment Plant

摘要

The control and communication record analysis device of the instrumentation control device for a water treatment plant of the present invention is an urgent need by checking in advance whether the wastewater treatment facility operates normally in wastewater and water treatment facilities, and taking measures to cause problems in the chemical treatment facility in advance. The purpose is to secure the safety of the wastewater treatment process by preventing the delay in the wastewater treatment process that requires the use. Accordingly, the control and communication record analysis apparatus of the instrumentation control device for a water treatment plant according to an embodiment of the present invention includes a field facility configured to measure and maintain water quality of wastewater and water treatment facilities; An instrumentation control device connected to the field facility and installed for operation at the site of wastewater and water treatment facilities, receiving status and measurement information of the field facility, and transmitting a control signal to the field facility; A host server connected to the instrumentation control device through a communication network and installed at a remote location, receiving status and measurement information of the field facility from the instrumentation control device, and transmitting a control signal for the field facility; A terminal unit connecting the instrumentation control device and field equipment; A recording and analysis device for recording and analyzing control signals and communication signals transmitted/received between the host server and the terminal unit, wherein the terminal unit includes: a monitoring terminal for receiving the status of field facilities and measurement information to the instrumentation control device; And a control terminal receiving a control signal from the instrumentation control device and providing it to the field facility.
