Problems solved by technology

This method solves some problems to some extent, but there are still the following disadvantages: 1. One-to-one matching equipment will increase the implementation cost; 2. A single video surveillance device often has blind spots in vision, and it is necessary to manually call other video surveillance devices Only then can we see the whole picture of the fire; 3. With the increase of functions of the new equipment formed by integration, the possibility of failure is also increasing
The disadvantages of this method are: 1. Each configuration or modification requires a lot of manpower and time to complete; 2. The change, increase or decrease of a single device requires modification of many related devices; 3. When the fire spreads, causing Some facilities are damaged, the pre-configured information cannot be used, and the device needs to be called manually

Embodiment 1

[0032] Building A is a high-rise building, and the building structure of each floor is similar. The equipment that can send out fire alarm signals includes smoke alarms and temperature sensors. The corner position, there is no need for video capture on the back side.

[0033] Such as figure 1 As shown in , establish a linkage system between the fire alarm signal and surveillance video of a certain building A. First draw a separate two-dimensional coordinate system for each floor according to the floor, draw the building structure in the form of a line drawing into the two-dimensional coordinate system with reference to the position in the real space, and then use the coordinates of the fire sensors and video surveillance devices in the area Points are plotted to a two-dimensional coordinate system. Secondly, carry out linkage judgment, if there is a result that can be connected in a straight line and does not intersect with other lines or structures between the coordinate po...

Embodiment 2

[0035] Building B is a high-rise building. The building structure of each floor is similar. The equipment capable of sending out fire alarm signals includes smoke alarms and temperature sensors. Type monitoring heads are arranged in the corners of the building, and spherical cameras are set up in other areas.

[0036] Such as figure 2 As shown in , establish a linkage system between the fire alarm signal and surveillance video of a certain building B. First draw a separate two-dimensional coordinate system for each floor according to the floor, draw the building structure in the form of a line drawing into the two-dimensional coordinate system with reference to the position in the real space, and then use the coordinates of the fire sensors and video surveillance devices in the area Points are drawn in the two-dimensional coordinate system, and at the same time, the monitorable range ∠B of the dome camera with adjustable viewing angle is set. Secondly, carry out linkage jud...

Embodiment 3

[0038]Building C is a multi-storey building. The building structure of each floor is similar. The equipment capable of sending out fire alarm signals includes smoke alarms and temperature sensors. Gun-type surveillance heads are arranged at the corners of the building, and spherical cameras are set up in other areas. The single-floor area of ​​building C is relatively large, and there is a problem that multiple video monitoring devices can capture a fire sensor.

[0039] Such as image 3 As shown in , establish a linkage system between the fire alarm signal and surveillance video of a certain building C. First draw a separate two-dimensional coordinate system for each floor according to the floor, draw the building structure in the form of a line drawing into the two-dimensional coordinate system with reference to the position in the real space, and then use the coordinates of the fire sensors and video surveillance devices in the area Points are drawn in the two-dimensional...

Abstract

The invention proposes a method for linking a fire alarm signal with a monitoring video. Including the establishment of a response relationship, so that any fire sensor is associated with several video surveillance devices, and the association relationship is stored in the data server; the response process, when any fire sensor sends out an alarm signal, according to the association relationship stored in the data server , and project the monitoring images corresponding to the video monitoring device to the display interface of the monitoring center in sequence. The beneficial effect is that: through the method provided by the present invention, the automatic association configuration of the fire sensor and the video monitoring device in the complex building or vehicle is realized, and then the response of the associated video monitoring device is realized for any fire sensor alarm, saving The labor cost and time cost of configuration are reduced, the degree of automation is improved, and work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a method for linkage of fire alarm signals and monitoring video. Background technique [0002] In existing buildings or vehicles, a large number of fire sensors and video monitoring devices will be installed to prevent fires. Once a fire point occurs somewhere, the nearby fire monitoring devices will immediately send out an alarm, and the monitoring personnel will immediately call the nearby monitoring devices manually. Video view of the scene. However, with the increase in the complexity of buildings and vehicles, the number of these devices is also increasing. In a high-rise building with dozens of floors, there are tens of thousands of such facilities. Manually call or view These facilities are not quite in line with the development of the current situation. [0003] In order to solve this problem, Patent No. CN201320004152X (a fire prevention video linkage device fo...
