Embodiment

[0015] Refer to attached figure 1 , taking the image-based fire detection system adopted by Shatuo Power Plant as an example, the system includes image fire detector 1, composite cable 2, local chassis 3, signal centralized main cabinet 4 and power station industrial TV system 5, image fire detector 1 is the AE900 image fire detector, a total of 15 image fire detectors 1 are installed on site, and they are respectively installed in 2 central warehouses, 2 generator floors, 2 GIS rooms, 1 oil treatment room, and 2 water inlet corridors , 1 Tuoqing outlet platform, 1 Tuohuang outlet platform, 2 tailwater platforms, and 2 dams.

[0016] The image fire detector 1 is connected to the local cabinet 3 through the composite cable 2 respectively. The composite cable 2 is composed of a video cable, DC24V power cord and linkage cable. , The main signal centralized cabinet 4 is also connected to the industrial television system 5 of the power station.

[0017] The signal concentration m...

Abstract

The invention provides a power plant image type fire and temperature surveillance detection system which comprises image fire detectors, composite cables, in-situ cases, a signal concentrating mainframe and a power-station industrial television system. The image fire detectors are distributed in a power-plant fire surveillance area and are respectively connected with the in-situ cases through the composite cables, the in-situ cases and an AC220V power line are connected with the signal concentrating mainframe, and the signal concentrating mainframe is further connected with the power-station industrial television system. By the arrangement, the shortcoming that traditional point type fire detectors and line type fire detectors cannot judge fire accurately in large-space areas is overcome, and the power plant image type fire and temperature surveillance detection system belongs to the field of power plant safety surveillance.

Description

technical field [0001] The invention relates to a monitoring information publishing system, which belongs to the field of safety monitoring of hydropower plants. Background technique [0002] With the development and wide application of my country's hydropower plant monitoring system and the development and popularization of modern communication technology, it is one of the important subjects of hydropower plants to establish a set of practical and effective fire (smoke, flame) and temperature monitoring and detection systems. Point-type fire detectors and linear fire detectors cannot accurately judge the fire situation in important and large-space areas such as generator floors, turbine oil depots, and outlet platforms, and there are serious deficiencies. Contents of the invention [0003] The object of the present invention is to provide an image-based fire and temperature monitoring and detection system in a power plant to make up for the inability of traditional point-t...
