Embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the present utility model, rather than whole embodiment.Based on embodiment of the present utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
In existing automatic fire alarm system, as shown in Figure 1, comprise detector 110, circuit board 120, motherboard 130, display board 140 and alarm device 150, wherein, detector 110 and circuit board 120 communications, circuit board 120 and motherboard 130 communications, display board 140, alarm device 150 and motherboard 130 communications.Detector 110 is used for the fire-fighting situation at detection of fires scene, smog situation at detection of fires scene etc. for example, when smokescope surpasses alarm threshold value near detecting the installation site, by circuit board 120 and motherboard 130 communications, send corresponding fire alarm alarm by motherboard 130,140 pairs of warning messages of display board show that alarm device 150 can be used to give the alarm for alert speaker.Wherein, display board 140 and alarm device 150 can be installed in fire alarm control duty room the duty personnel is carried out fire alarm.But, according to background technology, because the normal unmanned of fire alarm control duty room, the operation conditions of automatic fire alarm system equipment can not get effectively monitoring and safeguards, when breaking out of fire, administration of the prevention and control unit can't in time grasp the actual conditions of scene of fire by fire alarm system, thereby can not formulate the condition of a disaster processing scheme and evacuation route according to the concrete condition of scene of fire, has limited the application and the function expansion of fire system warning system.
For solving the above-mentioned defective of prior art, the utility model proposes a kind of fire alarm network supervisory system, as shown in Figure 2, comprise video acquisition device 210, radio transmitting device 220, radio network gateway 230, client-server 240 and monitor terminal 250, wherein, video acquisition device 210 is connected with radio transmitting device 220, radio transmitting device 220 is sent to radio network gateway 230 with the video data that collects by wireless network, client-server 240 obtains video data by the internet from radio network gateway 230, is connected with the monitor terminal 250 of one or more execution monitoring functions for 240 times at client-server.
Video acquisition device 210 is a video camera, its quantity is one or more, can be installed in the fire alarm system pulpit and gather duty personnel's situation on duty, obtain fire alarm system equipment (relevant devices such as detector 110, loop 120, motherboard 130, display board 140 and warning device 150 as shown in fig. 1) ruuning situation in real time, be arranged on zones such as fire safety passage, fire safety evaluating hidden danger position, neighboring buildings or facility, these regional field conditions are carried out real time video collection.
Radio transmitting device 220 comprises 3G network video server 221 and 3G router two 22, and 3G network video server 221 is connected by the RJ45 interface with 3G router two 22.The video data that collects is carried out after a series of compressed encodings handle, by 3G network video server 221 and 3G router two 22 by wireless network transmissions to internet network or VPDN private network, and corresponding radio network gateway is set.Concrete, by the wireless video gateway is being set on the Internet, perhaps VPDN private network gateway is set at the VPDN private network, adopt the 3G wireless network with video Data Transmission to wireless video gateway or VPDN private network gateway.Wireless video gateway or VPDN private network gateway can receive the video data in a plurality of zones, a plurality of cities.
In third party regulators such as administration of the prevention and control unit, control center, fire-fighting detachment/squadrons client-server 240 is set, client-server 240 is connected with one or more monitor terminals 250 by internet and wireless video gateway or the communication of VPDN private network gateway for 240 times at client-server.By IE browser or special-purpose client software, monitor terminal 250 obtains relevant video data.Concrete, monitor terminal 250 according to the video data that obtains to the duty personnel of fire alarm chamber on duty on duty monitoring the whether, whether monitoring automatic fire alarm system equipment operate as normal, thereby in time grasp the actual conditions of scene of fire, supervise and supervise the fire facility situation of constituent parts, effectively prevent and eliminate the hidden danger of potential fire.
In the utility model; by the collection site video data and carry out the transmission of video data by wireless network; for example mechanisms such as administration of the prevention and control unit, control center, fire-fighting detachment/squadron monitor the operation conditions of fire alarm control duty room and monitoring automatic fire alarm system equipment; improve the fire-fighting supervision; guarantee the normal operation of fire alarm system equipment, thereby improve urban fire control information system management level.
When breaking out of fire, the positioning function of video data of gathering in real time according to video camera and fire alarm system equipment (for example among Fig. 1 detector 110 etc.), in time located exactly, report to the police in the specified place and the position of fire the condition of a disaster, formulate rational the condition of a disaster processing scheme and evacuation route.On the other hand; can be used for regional security alarm; for example for the area of breaking out of fire; effect by the utility model fire alarm network supervisory system; if periphery has warehouse or the factory that dangerous products is deposited; can in time grasp the fire situation, to realize that the resident of peripheral region withdrawn or security alarm the maximum magnitude protection security of the lives and property.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
