Description

Technical Field

[0001] The present disclosure relates to the technical field of building fire monitoring, and in particular to a fire monitoring system. Background Art

[0002] With the increase in large buildings, there are more and more potential fire hazards, and fire safety plays an increasingly important role. Once a fire occurs, the fire protection system can often play a role before the fire alarm arrives, which has an important impact on the control of the fire.

[0003] In order to make the fire protection system work accurately, there is usually a control module in the fire protection system to intelligently adjust the switch of the sprinkler head according to the fire situation. If only one control module is set up, the probability of failure may increase with the increase of working time, which reduces the working reliability of the fire monitoring system.

[0041] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0042] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0043] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0044] Figure 1 A schematic diagram of the structure of a fire monitoring system provided by an embodiment of the present disclosure. Figure 1 , the fire monitoring system includes an information collection device 10, a first control module 11, a second control module 12, a sprinkler device 16, a first selector module 15, a second selector module 13 and a timing module 14;

[0045] The first control module 11 and the second control module 12 are both connected to the information collection device 10;

[0046] The first control module 11 and the second control module 12 are both connected to the spraying device 16;

[0047] The first control module 11 and the second control module 12 are both connected to the first selector module 15;

[0048] The first control module 11 and the second control module 12 are both connected to the second selector module 13;

[0049] The first selector module 15 and the second selector module 13 are both connected to the timing module 14 .

[0050] The information collection device 10 is used to collect information of the fire protection area and transmit the information to the first control module 11 and the second control module 12 respectively.

[0051] Specifically, the information includes image information and thermal infrared information collected by the camera 101 , smoke concentration information collected by the smoke sensor 102 , and temperature information collected by the temperature sensor 103 .

[0052] Since the first control module 11 and the second control module 12 have the same functions, the first control module 11 is used as an example here, and the second control module 12 works in the same way. After receiving the information from the information collection module 10, the information is analyzed and calculated, and the calculation results are used to adjust the working state of the sprinkler 16. After receiving the instructions from the first control module 11, the sprinkler 16 adjusts the working state and sprays water on the area where the fire occurs.

[0053] Specifically, the first control module 11 compares the collected temperature information and / or smoke concentration information with the preset temperature threshold and the preset smoke concentration threshold, respectively. When the average temperature value is greater than or equal to the preset temperature threshold, and / or the average smoke concentration value is greater than or equal to the preset smoke concentration threshold, the result of "fire occurs" is obtained. The first control module 11 analyzes the specific location of the fire according to the image of the camera 101 and the thermal infrared information, and outputs instructions to the sprinkler equipment 16 to open the solenoid valve 161 and rotate the steering device 162, thereby rotating the sprinkler head 163 toward the specific location of the fire. If the analysis result of the first control module 11 is not "fire occurs", no signal is sent to the sprinkler, and the solenoid valve 161 closes after receiving no signal, and the steering device 162 stops rotating.

[0054] The timing module 14 changes the level output state every preset time period, and the level output state includes two types: high level and low level. The first selector module 15 and the second selector module 13 are adjusted in operation by the timing module 14. When the timing module 14 outputs a low level, the first selector module 15 outputs a low level, and the second control module 12 works normally after receiving the low level. The second selector module 13 outputs a high level, and the first control module 11 stops working after receiving the high level. When the timing module 14 outputs a high level, the first selector module 15 outputs a high level, and the second control module 12 stops working after receiving the high level. The second selector module 13 outputs a low level, and the first control module 11 works normally after receiving the low level.

[0055] The first control module 11 and the second control module 12 will work alternately at preset time intervals to reduce the loss caused by excessive use. The normal operation of either the first control module 11 or the second control module 12 can ensure the normal operation of the fire monitoring system and improve the reliability of the system.

[0056] In one embodiment, referring to Figure 2 , the information collection device 10 includes:

[0057] Camera 101, smoke sensor 102, temperature sensor 103;

[0058] The camera 101, the smoke sensor 102, and the temperature sensor 103 are all connected to the first control module;

[0059] The camera 101, the smoke sensor 102, and the temperature sensor 103 are all connected to the second control module;

[0060] The camera 101 collects infrared information and sends the infrared information to the first control module 11 and the second control module 12 respectively.

[0061] The smoke sensor 102 collects smoke density information and sends the smoke density information to the first control module 11 and the second control module 12 respectively.

[0062] The temperature sensor 103 collects temperature information and sends the temperature information to the first control module 11 and the second control module 12 respectively.

[0063] Since the functions of the first control module 11 and the second control module 12 are the same, the first control module 11 is used as an example here, and the second control module 12 is the same. The first control module 11 compares the temperature information and / or smoke concentration information with the preset temperature threshold and the preset smoke concentration threshold respectively; when the average temperature value is greater than or equal to the preset temperature threshold, and / or the average smoke concentration value is greater than or equal to the preset smoke concentration threshold, the working state of the sprinkler 16 is adjusted according to the image of the camera 101 and the thermal infrared information, specifically including: the first control module 11 compares the collected temperature information and / or smoke concentration information with the preset temperature threshold and the preset smoke concentration threshold respectively, and when the average temperature value is greater than or equal to the preset temperature threshold, and / or the average smoke concentration value is greater than or equal to the preset smoke concentration threshold, the result of "fire occurs" is obtained, and the first control module 11 analyzes the specific location of the fire according to the image of the camera 101 and the thermal infrared information, and outputs instructions to the sprinkler 16 to open the solenoid valve 161 and rotate the steering device 162, thereby rotating the sprinkler head 163 toward the specific location of the fire. If the analysis result of the first control module 11 is not "fire", no signal is sent to the sprinkler device. After the solenoid valve 161 does not receive the signal, the valve is closed and the steering device 162 stops rotating.

[0064] The first control module 11 analyzes the image information and thermal infrared information of the camera to determine the number of flames, the distribution positions of the flames and the sizes of the flames in the area around the camera installation location.

[0065] The first control module 11 and the second control module 12 then adjust the water spray flow rate and / or water spray duration of the spray device 16 according to the number of flames, the distribution position of the flames and the size of the flames in the surrounding area;

[0066] This embodiment enables the fire monitoring system to determine the extent of the fire and extinguish the fire by itself after a fire occurs.

[0067] In one embodiment, referring to Figure 2 , the spraying equipment 16 comprises:

[0068] Solenoid valve 161 , steering device 162 and sprinkler head 163 .

[0069] The solenoid valve 161 is connected to the first control module 11 , the second control module 12 and the spray head 163 respectively.

[0070] The steering device 162 is connected to the first control module 11 , the second control module 12 and the spray head 163 respectively.

[0071] The solenoid valve 161 is used to control the spraying state of the spray head 163 .

[0072] The steering device 162 is used to adjust the water spraying direction of the sprinkler head 163.

[0073] After the first control module 11 and the second control module 12 send instructions to the solenoid valve 161 and the steering device 162 , the solenoid valve 161 and the steering device 162 change their working states, thereby changing the water spraying state of the sprinkler head 163 .

[0074] Specifically, since the functions of the first control module 11 and the second control module 12 are the same, the first control module 11 is used as an example here, and the second control module 12 is the same. When a fire occurs, the first control module 11 sends an "open solenoid valve" command to the solenoid valve 161, and the solenoid valve 161 opens the solenoid valve switch after receiving the signal. The steering device 162 is preset with four moving directions: front, back, left, and right. When the first control module 11 sends a command to the steering device 162, it will send four information of front, back, left, and right according to the fire situation, accurately adjust the position of the steering device, and then adjust the direction of the sprinkler head.

[0075] This embodiment enables the sprinkler head 163 to spray water precisely toward the fire, thereby enhancing the fire control of the fire protection system.

[0076] In one embodiment, referring to Figure 2 , the fire monitoring system also includes a liquid level sensor 17;

[0077] The liquid level sensor 17 is connected to the first control module 11 and the second control module 12 respectively;

[0078] The liquid level sensor 17 collects the liquid level information of the water tank and transmits it to the first control module 11 and the second control module 12. If the liquid level is lower than the preset height information, the first control module 11 and the second control module 12 issue an early warning through the alarm module 18.

[0079] In one embodiment, referring to Figure 2 The fire monitoring system includes a display module 19,

[0080] The display module 19 is connected to the first control module 11 and the second control module 12 respectively;

[0081] The display module 19 is located in the security room and is used to display the monitoring image of the fire area. When a fire occurs, the location and size of the fire can be displayed.

[0082] The first control module 11 and the second control module 12 organize the obtained fire information and send it to the display module 19;

[0083] This embodiment allows the fire situation to be known to people more quickly, making it easier to extinguish the fire.

[0084] In one embodiment, the fire monitoring system further includes an alarm module 18.

[0085] The alarm module 18 is connected to the first control module 11 and the second control module 12 respectively.

[0086] The alarm module 18 is used to indicate the liquid level information and the escape method after a fire occurs.

[0087] This embodiment can help relevant personnel to obtain information on the liquid level so as to replenish fire-fighting water in time and avoid the situation where there is no water available after a fire occurs. It can also prompt people near the fire to escape in time after a fire occurs.

[0088] In one embodiment, referring to Figure 3 The first selector module 15 and the second selector module 13 both include a two-to-one selector.

[0089] The two-choice selector outputs a-terminal level signal when s1 terminal is at a low level, and outputs b-terminal level signal when s1 terminal is at a high level. The first control module 11 and the second control module 12 can execute corresponding working states according to different level signals.

[0090] The timing module 14 outputs signals of different levels.

[0091] When the selector outputs a low level, the first control module 11 works and the second control module 12 does not work. When the selector outputs a high level, the first control module 11 does not work and the second control module 12 works.

[0092] In this embodiment, the first control module 11 and the second control module 12 work alternately, thereby avoiding the problem of accelerated damage caused by long-term operation.

[0093] In one embodiment, the timing module 14 includes:

[0094] Timer and level output;

[0095] The timer is connected to the level output device;

[0096] The level output device is connected to the first selector module and the second selector module respectively;

[0097] The timer changes the working state of the level output device every preset time interval;

[0098] The level follower outputs high level and low level.

[0099] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
