Embodiment 1

[0045] RS485 half-duplex mode communication interface is adopted, and RS485 bus communication is adopted between two subsystems using this interface to exchange information. The physical connection between the two subsystems adopts shielded cables or optical cables. When the communication modules of the two subsystems are arranged in the same building (such as the main control building), shielded twisted pair communication is used, and the physical communication interface connection diagram is as follows figure 1 shown. When the communication modules of the two subsystems are arranged in different buildings (for example, the fire alarm host is arranged in the police room, and the video surveillance host is arranged in the main control building), the armored multi-mode optical cable is used for communication, and two additional A photoelectric conversion device, the photoelectric conversion device and its respective subsystems are connected through the RS485 bus, and the two ph...

Embodiment 2

[0053] The RJ45 network port based on TCP / IP, the two subsystems that use this interface to exchange information, use the network communication based on TCP / IP, the physical connection between the two subsystems adopts super five types of Ethernet cables or optical cables, the two subsystems The systems are connected through switches. When the communication modules of the two subsystems are arranged in the same building (such as the main control building), they use Cat5e Ethernet cables for communication, and the physical communication interface connection diagram is as follows image 3 shown. When the communication modules of the two subsystems are arranged in different buildings (for example, the fire alarm host is arranged in the police room, and the video surveillance host is arranged in the main control building), the armored multi-mode optical cable is used for communication, and the physical communication interface connection diagram is as follows Figure 4 shown.

Abstract

The invention discloses a fire warning and video monitoring linkage system of a direct-current converter station. The fire warning and video monitoring linkage system comprises a fire warning subsystem, a video monitoring subsystem and a communication module. The fire warning subsystem and the video monitoring subsystem pass through a communication interface of the communication module and conduct linkage communications based on a Modbus communication protocol, and thus linkage warning can be achieved through data analysis. The specific steps are that the fire warning subsystem sends an address code of a fire sensor in a fire alarm occurring place to the video monitoring subsystem, after the video monitoring subsystem receives the address code of the fire sensor, a camera in an actual area corresponding to the address code of the fire sensor is inquired through an address code mapping table, and the video monitoring subsystem is switched to a corresponding camera picture. By means of the fire warning and video monitoring linkage system of the direct-current converter station, the video monitoring system can immediately and automatically push out the monitoring picture of a fire scene when fire alarm happens, and the original function of an original fire warning subsystem and the original function of an original video monitoring subsystem can not be affected.

Description

technical field [0001] The invention relates to the field of electric power transmission, in particular to a fire alarm and video monitoring linkage system of a DC converter station. Background technique [0002] Generally, the DC converter station is equipped with a fire alarm system and a video surveillance system. Among them, the function of the fire alarm system is to monitor the valve hall, converter transformer, station transformer, main control building, auxiliary control building, relay cell, comprehensive building, spare parts warehouse, garage, comprehensive pump room, and police room in the converter station. Real-time fire monitoring in all fire-probable areas such as , cable interlayer, and cable shaft. In the event of a fire, immediately start the alarm bell in the station, send out an emergency broadcast, link fire extinguishing equipment, and make an emergency landing on the elevator. The function of the video monitoring system is to monitor the valve hall,...
