Inspection remote control system and method for cooperative protection with fire-fighting system

Abstract

The invention relates to an inspection remote control system and method for cooperative protection with a fire extinguishing system. The system comprises an SCADA system and a video monitoring system,and the SCADA system comprises a monitoring computer, a PLC system, a man-machine interface, and a collection device. The fire extinguishing system comprises a fire detector and a fire alarm controller. The fire detector is used for collecting the concentration of natural gas, the temperature of a gas conveying pipeline and the concentration of flue gas in a fireproof subarea and uploading the above data to a monitoring computer. The fire alarm controller is in communication connection with the PLC system and is used for outputting an alarm signal when the natural gas concentration, the gas transmission pipeline temperature or the flue gas concentration exceeds the limit, and the monitoring computer controls the PLC system to control the running state of onsite equipment according to thealarm signal. The system and method have the advantages that the fire extinguishing system information can be accessed to the station control SCADA system, so that the fire alarm system information can be displayed on the SCADA system, the information of the whole station control system is platformized, and fire alarm processing and station control system processing can be both considered when a fire occurs.

Description

technical field [0001] The invention relates to the technical field of natural gas transmission and distribution control and fire alarm, in particular to a patrol inspection remote control system and method thereof for coordinated protection with a fire protection system. Background technique [0002] With economic development and environmental emphasis, natural gas has been widely used. The monitoring control and data acquisition system with industrial computer as the core, that is, SCADA system, has gradually become the core of pipeline system management and control. The SCADA system has real-time and reliable acquisition capabilities and remote control capabilities, and can integrate real-time monitoring and information systems. [0003] At the same time, for the field of natural gas transmission and distribution, the fire alarm system is also indispensable. The existing fire alarm system and the station control system of the natural gas station are independent systems, ...

Problems solved by technology

[0003] At the same time, for the field of natural gas transmission and distribution, the fire alarm system is also indispensable. The existing fire alarm system and the station control system of the natural gas station are independent systems, and the information is not connected with each other. The SCADA station control system is generally staffed 24 hours a day On duty, but few people pay attention to the fire alarm system on a daily basis. They only pay attention to it when there is an alarm. When there is a fire alarm, the first thing the personnel think of is to deal with the fire situation, while ignoring the related problems of the station control system, such as: Regarding the disposal of natural gas shut-off valves and other valves, whether it is necessary to close the natural gas shut-off valve according to the fire situation
