Description

Technical Field

[0001] The present invention relates to the technical field of fire passage monitoring, and more specifically, to a fire scene fire passage monitoring system and a monitoring method. Background Art

[0002] A fire passage refers to a passage for firefighters to carry out rescue and evacuate trapped people. For example, there are fire indicators installed at the stairwells and aisles. The fire passage plays an underestimated role in various emergencies.

[0003] Currently, for the monitoring of fire passages, basically the method of monitoring cameras is adopted. Although it can play a certain monitoring role under normal conditions, such as monitoring the opening and closing state of fire doors and whether the fire passage is blocked, etc., this monitoring method is extremely vulnerable to the interference of thick smoke generated by a fire during a fire, resulting in temporary monitoring failure. And once there is one or more such areas with unclear monitoring in a complete escape route, the danger of the entire escape route will be greatly enhanced. There is a need for a fire scene fire passage monitoring system and a monitoring method that can effectively monitor the state of the fire passage both under normal conditions and during a fire.

[0013] For the fire scene fire passage monitoring system described in the present invention, an annular section sleeving the camera unit is formed on the spray pipeline, and a plurality of high-pressure spray heads are evenly distributed on the annular section; when the fire passage section has been detected for unobstructedness, the control host triggers the plurality of high-pressure spray heads on the annular section to enter the high-pressure spray mode to reduce the smoke and dust around the camera unit.

[0026] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] The fire scene fire access monitoring system in a preferred embodiment of the present invention, as Figure 1 shown, and referring to Figure 2 and Figure 3 simultaneously, includes a fire access provided inside a building. The fire access is composed of multiple spliced fire sections, and also includes a control host for remote control. Among them:

[0028] A camera unit 1 is provided at the top of the fire section, and a spray pipeline 2 is provided along the length extension direction of the fire section; a receiving pipeline 3 is provided at the bottom of the fire section directly below the spray pipeline 2; a plurality of spray heads 20 are provided on the spray pipeline 2, and a plurality of liquid receiving holes 30 corresponding to the spray heads one by one are provided on the receiving pipeline 3, and a liquid sensor 31 is provided in the liquid receiving hole 30;

[0029] The control host receives the monitoring images of the camera unit 1, and controls the trigger of the spray pipeline 2 to enter the dripping mode when the monitoring images are blocked by thick smoke; in the dripping mode, the plurality of spray heads 20 of the spray pipeline 2 drip at a set speed, the liquid receiving holes 30 receive the water droplets from the corresponding spray heads 20, and the corresponding liquid sensors 31 perform dripping monitoring; the control host determines whether the current fire section is unobstructed based on the data of the plurality of liquid sensors 31;

[0030] The control host receives the monitoring images of the camera unit 1 and feeds back to the outside whether the current fire section is unobstructed according to the monitoring images; when the monitoring images are blocked by thick smoke, it controls to trigger the spray pipeline 2 to enter the dripping mode; in the dripping mode, multiple spray heads 20 of the spray pipeline 2 drip at a set speed, the liquid receiving holes 30 receive the water droplets from the corresponding spray heads 20, and the corresponding liquid sensors 31 conduct dripping monitoring; the control host judges whether the current fire section is unobstructed based on the data of multiple liquid sensors 31;

[0031] Based on the existing monitoring cameras, further improvements are made. The spray pipeline and the receiving pipeline are added, and the three are organically combined into a set of systems. The new system can not only perform conventional video monitoring operations, but also monitor the unobstructedness of the fire section in case of thick smoke. At the same time, it also has the effect of cooling and extinguishing fires in the fire section, greatly improving the overall safety performance of the fire passage.

[0032] Preferably, a plurality of temperature sensors 32 are also distributed on the outer surface of the receiving pipeline 3. The control host receives the data of multiple liquid sensors 31 and at the same time receives the data of multiple temperature sensors 32 and feeds back to the outside; the control host judges whether the temperature of the current fire section is higher than the set passable temperature threshold based on the data of multiple temperature sensors 32; the structure is reasonably arranged and can perform multi-point temperature monitoring of the fire section. According to the multi-point temperatures, it can be determined whether the current fire section is suitable for people to pass; in addition, it can also be set that: when the temperature of the current fire section is higher than the set passable temperature threshold, the control host marks the corresponding fire section in red and displays it to the outside; when the temperature of the current fire section is lower than the set passable temperature threshold, the control host marks the corresponding fire section in green and displays it to the outside; this can provide visual identification for the console and facilitate the guidance of safe paths.

[0033] Preferably, when the temperature of the current fire section is higher than the set passable temperature threshold and the unobstructed detection of the fire section has been completed, the control host triggers the spray pipeline to enter the spraying mode; in the spraying mode, multiple spray heads of the spray pipeline start spraying to cool the fire section; when the section is unobstructed and the temperature is too high, the spraying function can be turned on. However, if the section itself is unobstructed due to various external factors, turning on the spray at this time has little practical significance. In the case of limited water storage, priority should be given to cooling the passable fire sections.

[0034] Preferably, an installation groove 4 for installing the receiving pipeline is provided at the bottom of the fire-fighting section. After the receiving pipeline 3 is installed, there is a gap between the inner wall and the bottom surface of the installation groove 4. A drainage groove 40 is provided at the bottom of the installation groove 4; the receiving pipeline 3 is circular and an annular groove 33 is formed on its surface; the liquid receiving hole 30 is located on the lower surface of the receiving pipeline 3 and communicates with the annular groove 33; a drainage cotton rope 34 is wound around the annular groove 33, and the detection pin of the liquid sensor 31 is inserted into the drainage cotton rope 34; the temperature sensor 32 is embedded on the upper surface of the receiving pipeline 3; a data line 35 for exporting the data of multiple liquid sensors and multiple temperature sensors and a wireless communication unit are arranged inside the receiving pipeline 3, and the wireless communication unit is used to externally send the data to the control host;

[0035] While the installation groove is used to install the receiving pipeline, if a large amount of water enters the installation groove, most of the water will flow down from the gap between the installation groove and the receiving pipeline and be quickly discharged by the drainage groove. A small amount of water is absorbed by the drainage cotton rope and triggers the liquid sensor, but it will also evaporate naturally relatively quickly. In this way, the situation of a large amount of water entering the installation groove is dealt with; the liquid receiving hole is arranged on the lower surface of the receiving pipeline instead of the upper surface, which can effectively prevent dust from blocking the liquid receiving hole. At the same time, relying on the liquid absorption ability of the drainage cotton rope, the dripping liquid of the sprinkler head can be effectively absorbed. When the drainage cotton rope is wet, it will trigger the liquid sensor to ensure the triggering reliability; through this structural design, the inside of the liquid receiving pipeline can also be kept dry and will not get water, which is very convenient for laying the data line; in addition, this layout structure design can also ensure the overall appearance integrity and is suitable for ground installation in various places such as the lobby and the conference room.

[0036] Preferably, an annular section 21 sleeving the camera unit is formed on the spray pipeline 2, and a plurality of high-pressure spray heads 22 are evenly distributed on the annular section 21; when the control host has completed the detection of the smoothness of the fire-fighting section, it triggers the plurality of high-pressure spray heads 22 on the annular section to enter the high-pressure spray mode to reduce the smoke and dust around the camera unit 1;

[0037] A method for monitoring a fire scene fire-fighting passage, which applies the fire scene fire-fighting passage monitoring system as described above, includes the following steps:

[0038] Assembly stage:

[0039] A camera unit is provided at the top of the fire-fighting section and a spray pipeline is arranged along the length extension direction of the fire-fighting section; a receiving pipeline is arranged at the bottom of the fire-fighting section directly below the spray pipeline; a plurality of spray heads are arranged on the spray pipeline, and a plurality of liquid receiving holes corresponding to the spray heads one by one are arranged on the receiving pipeline, and a liquid sensor is arranged in the liquid receiving hole;

[0040] Real-time monitoring stage:

[0041] The control host receives the monitoring screen of the camera unit and feeds back to the outside whether the current fire section is unobstructed according to the monitoring screen; when the monitoring screen is blocked by thick smoke, it controls to trigger the spray pipeline to enter the dripping mode; in the dripping mode, multiple spray heads of the spray pipeline drip at a set speed, the liquid receiving holes receive the water droplets from the corresponding spray heads, and the corresponding liquid sensors conduct dripping monitoring; the control host judges whether the current fire section is unobstructed based on the data of multiple liquid sensors;

[0042] Based on the existing monitoring cameras, further improvements have been made. The spray pipeline and the receiving pipeline have been added, and the three have been organically combined into a set of systems. The new system can not only perform conventional video monitoring operations, but also monitor the unobstructedness of the fire section under thick smoke conditions. At the same time, it also has the effect of cooling and extinguishing fires in the fire section, greatly improving the overall safety performance of the fire passage.

[0043] Preferably, the method further includes the steps:

[0044] The control host judges whether the temperature of the current fire section is higher than the set passable temperature threshold. When the temperature of the current fire section is higher than the set passable temperature threshold and the unobstructed detection of the fire section has been completed, it triggers the spray pipeline to enter the spraying mode; in the spraying mode, multiple spray heads of the spray pipeline start spraying to cool the fire section; when the temperature of the current fire section is higher than the set passable temperature threshold, the control host marks the corresponding fire section in red and displays it to the outside; when the temperature of the current fire section is lower than the set passable temperature threshold, the control host marks the corresponding fire section in green and displays it to the outside;

[0045] It can perform multi-point temperature monitoring on the fire section. According to the multi-point temperature, it can determine whether the current fire section is suitable for people to pass through; in addition, it can also give visual markings to the console to facilitate safe path guidance.

[0046] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present invention.
