Description

Technical Field

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

[0002] When a fire breaks out, panic easily spreads among the crowd. In crowded public places like shopping malls and theaters, panicked people may flee blindly, leading to stampedes. In such a chaotic situation, people may be pushed or trampled, suffering injuries such as fractures and suffocation. When a fire breaks out, the direction of its spread is uncertain. If evacuation signs are fixed in a certain direction, and the fire happens to be spreading in that direction, they will lead people into the danger zone. However, fixed evacuation direction signs may not be able to dynamically adjust to the fire's spread, resulting in people being directed into smoke-filled or flame-filled passages.

[0036] To help those skilled in the art better understand this solution, the following will clearly describe the technical solutions in the embodiments of this solution in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of this solution, not all of it. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of this solution.

[0037] Throughout the specification, claims, and accompanying figures of this solution, the term "including" and any variations thereof mean "including, but not limited to," and are intended to cover non-exclusive inclusions and are not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish between different objects, not to describe a specific order.

[0038] The following describes the implementation of the present disclosure in detail with reference to the accompanying drawings:

[0039] Figure 1 This is a structural diagram of a fire monitoring system provided by an embodiment of the present disclosure. Figure 1 The fire monitoring system includes: a first flame detection module 10, a second flame detection module 11, a first comparator module 12, a first central control module 13, a switch module 14, a second comparator module 15, a second central control module 16 and an evacuation direction display module 17;

[0040] The first flame detection module 10 and the second flame detection module 11 are both connected to the first comparator module 12;

[0041] The first central control module 13 is connected to the first comparator module 12 and the switch module 14 respectively;

[0042] The switch module 14 is connected to the first flame detection module 10, the second flame detection module 11 and the second comparator module 15 respectively;

[0043] The second central control module 16 is connected to the second comparator module 15 and the evacuation direction display module 17 respectively;

[0044] The first flame detection module 10 and the second flame detection module 11 are flame detection modules at adjacent outlets.

[0045] In this embodiment, the first flame detection module 10 is configured to detect the infrared radiation value of the first area, and the second flame detection module 11 is configured to detect the infrared radiation value of the second area. The first area and the second area are two adjacent safety exit areas.

[0046] The first comparator module 12 is configured to compare the infrared radiation value detected by the first flame detection module 10 with a preset first reference flame signal. The first comparator module 12 is also configured to compare the infrared radiation value detected by the second flame detection module 11 with a preset first reference flame signal.

[0047] The first central control module 13 is configured to receive information sent by the first comparator module 12 and control the switch module 14 to be turned on or off.

[0048] The second comparator module 15 is configured to compare the infrared radiation value detected by the first flame detection module 10 with the infrared radiation value detected by the second flame detection module 11 .

[0049] The second central control module 16 is configured to receive information sent by the second comparator module 15 and control the display direction of the evacuation direction display module 17 .

[0050] For example, there are two safety exits on the same floor, namely safety exit A and safety exit B. The preset first reference flame signal is 60 milliwatts per square centimeter. The first flame detection module 10 detects that the infrared radiation value at safety exit A is 30 milliwatts per square centimeter and sends it to the first comparator module 12. The second flame detection module 11 detects that the infrared radiation value at safety exit B is 40 milliwatts per square centimeter and sends it to the first comparator module 12. At this time, the first comparator module 12 compares the above two data with the preset first reference flame signal, both of which are less than 60 milliwatts per square centimeter, so it sends "0" and "0" to the first central control module 13, that is, no fire has occurred, and the first central control module 13 does not take any action. At this time, the direction displayed by the evacuation direction display module 17 points to the safety exit closest to the current position.

[0051] After a period of time, the first flame detection module 10 detects that the infrared radiation value at the safety exit A is 30 milliwatts per square centimeter and sends it to the first comparator module 12. The second flame detection module 11 detects that the infrared radiation value at the safety exit B is 70 milliwatts per square centimeter and sends it to the first comparator module 12. At this time, the first comparator module 12 compares the above two data with the preset first reference flame signal. The infrared radiation value detected by the first flame detection module 10 is 30 milliwatts per square centimeter, which is less than 60 milliwatts per square centimeter. The infrared radiation value detected by the first flame detection module 10 is 70 milliwatts per square centimeter, which is greater than 60 milliwatts per square centimeter. centimeters, so "0" and "1" are sent to the first central control module 13, that is, no fire occurs at safety exit A, and a fire occurs at safety exit B. The first central control module 13 controls the switch module 14 to be turned on, and the second comparator 122 receives the infrared radiation value detected by the first flame detection module 10 and the infrared radiation value detected by the second flame detection module 11, and compares them. Since the infrared radiation value sent by the second flame detection module 11 is greater than the infrared radiation value sent by the first flame detection module 10, the output can be "0", and the comparison result is sent to the second central control module 16. After receiving "0", the second central control module 16 controls the display direction of the evacuation direction display module 17 to point to safety exit A.

[0052] As can be seen from the above, the present disclosure can achieve early warning of fires by detecting the infrared radiation values ​​of two adjacent safety exit areas through the first flame detection module 10 and the second flame detection module 11, respectively, and comparing them with a pre-set first reference flame signal. When the present disclosure detects a fire, the first central control module 13 controls the switch module 14 to conduct, while the second central control module 16 controls the evacuation direction display module 17 based on the result of the second comparator 122. If a fire occurs in a safety exit area, the present disclosure can intelligently instruct people to evacuate to a safety exit not affected by the fire, thereby improving evacuation efficiency and safety, helping to provide the most effective evacuation path in an emergency, and improving the reliability and accuracy of fire escape instructions.

[0053] In one embodiment of the present disclosure, the first comparator module 12 includes: a first comparator 121 and a second comparator 122;

[0054] The first comparator 121 has a non-inverting input terminal connected to the first flame detection module 10 , an inverting input terminal for receiving a first reference flame signal, and an output terminal connected to the first central control module 13 ;

[0055] The second comparator 122 has a non-inverting input terminal connected to the second flame detection module 11 , an inverting input terminal for receiving the first reference flame signal, and an output terminal connected to the first central control module 13 .

[0056] In one embodiment of the present disclosure, the switch module 14 includes: a first switch 141 and a second switch 142;

[0057] The first end of the first switch 141 is connected to the first flame detection module 10, the second end is connected to the second comparator module 15, and the control end is connected to the first central control module 13;

[0058] The first end of the second switch 142 is connected to the second flame detection module 11, the second end is connected to the second comparator module 15, and the control end is connected to the first central control module 13;

[0059] The first switch 141 and the second switch 142 are normally open switches.

[0060] In one embodiment of the present disclosure, the second comparator module 15 is a cascade comparator module;

[0061] The second comparator module 15 is configured to send the comparison result to the second central control module 16 .

[0062] In one embodiment of the present disclosure, the evacuation direction display module 17 includes: a first evacuation direction display unit 171 and a second evacuation direction display unit 172;

[0063] The first evacuation direction display unit 171 and the second evacuation direction display unit 172 are both connected to the second central control module 16;

[0064] The first evacuation direction display unit and the second evacuation direction display unit 172 are evacuation direction display units at adjacent exits.

[0065] In this embodiment, the first comparator 121 is configured to compare the infrared radiation value detected by the first flame detection module 10 with a preset first reference flame signal; the second comparator 122 is configured to compare the infrared radiation value detected by the second flame detection module 11 with a preset first reference flame signal.

[0066] The first central control module 13 is configured to control the first switch 141 and the second switch 142 to be closed when receiving “1”.

[0067] The second comparator module 15 is a cascaded 74LS38 comparator module, which can output three signals: "100", "010" and "001", which respectively correspond to: the infrared radiation value detected by the first flame detection module 10 is greater than the infrared radiation value detected by the second flame detection module 11, the infrared radiation value detected by the first flame detection module 10 is equal to the infrared radiation value detected by the second flame detection module 11, and the infrared radiation value detected by the first flame detection module 10 is less than the infrared radiation value detected by the second flame detection module 11.

[0068] The first evacuation direction display unit 171 and the second evacuation direction display unit 172 are each configured to display the direction of the emergency exit closest to the current position. The first evacuation direction display unit 171 and the second evacuation direction display unit 172 are arranged around adjacent emergency exits.

[0069] The second central control module 16 is configured to receive the signal sent by the second comparator module 15 and control the directions of the first evacuation direction display unit 171 and the second evacuation direction display unit 172 .

[0070] For example, there are two emergency exits on the same floor, namely, emergency exit C and emergency exit D. The first evacuation direction display unit 171 is close to emergency exit C, and the second evacuation direction display unit 172 is close to emergency exit D. The preset first reference flame signal is 65 milliwatts per square centimeter. The first flame detection module 10 detects that the infrared radiation value at emergency exit C is 70 milliwatts per square centimeter and sends it to the first comparator 121. The second flame detection module 11 detects that the infrared radiation value at emergency exit D is 85 milliwatts per square centimeter and sends it to the second comparator 122. Since 70 milliwatts per square centimeter is greater than 65 milliwatts per square centimeter, the first comparator 121 sends "1" to the first central control module 13. Since 85 milliwatts per square centimeter is greater than 65 milliwatts per square centimeter, the first comparator 121 sends "1" to the first central control module 13. At this time, the first central control module 13 receives two "1s" and controls the first switch 141 and the second switch 142 to be closed. At this time, the first flame detection module 10 sends the detected infrared radiation value to the second comparator module 15, and the second flame detection module 11 sends the detected infrared radiation value to the second comparator module 15. The second comparator module 15 compares the two. Since 85 milliwatts per square centimeter is greater than 65 milliwatts per square centimeter, "001" is sent to the second central control module 16, which means that the fire at safety exit D is greater than the fire at safety exit C. Therefore, the directions displayed by the first evacuation direction display unit 171 and the second evacuation direction display unit 172 are both controlled to point to safety exit C.

[0071] Even if a fire occurs at the safety exit C which is a distance away from the first evacuation direction display unit 171, since there are only two safety exits on this floor and the fire at the safety exit D is greater than the fire at the safety exit C, the direction displayed by the first evacuation direction display unit 171 still points to the safety exit C.

[0072] Even though the second evacuation direction display unit 172 is relatively close to the safety exit D, the direction displayed by the second evacuation direction display unit 172 points to the safety exit C because the fire intensity is greater than the fire intensity of the safety exit C.

[0073] Or, for example, after the first time, the first flame detection module 10 detects that the infrared radiation value at the safety exit C is 65 milliwatts per square centimeter, and the second flame detection module 11 detects that the infrared radiation value at the safety exit C is 65 milliwatts per square centimeter. The second comparison module sends "010" to the second central control module 16, that is, the fire size at the safety exit C and the safety exit D are equal. At this time, the second central control module 16 controls the direction displayed by the first evacuation direction display unit 171 and the second evacuation direction display unit 172 to point to the safety exit closest to the current position, that is, the direction displayed by the first evacuation direction display unit 171 points to the safety exit C, and the direction displayed by the second evacuation direction display unit 172 points to the safety exit D.

[0074] From the above, it can be concluded that when the present disclosure detects a fire, the first central control module 13 can control the closure of the switch module 14 according to the output of the comparator, and then pass the data of the flame detection module to the second comparator module 15 for further comparison. The above design can flexibly adjust the evacuation guidance strategy according to different fire situations. The present disclosure can intuitively indicate the best evacuation path through the first evacuation direction display unit 171 and the second evacuation direction display unit 172, which helps to quickly guide people to evacuate in an emergency and reduce panic and confusion. The present disclosure can handle a variety of fire situations, including a fire at a single safety exit, a fire at both safety exits but with different fire intensities, etc. By comparing the data of the two flame detection modules, the present disclosure can intelligently select the safety exit with the smaller fire as the evacuation path, or instruct people to evacuate to the nearest safety exit when the fire intensities are equal, thereby improving the reliability and accuracy of fire escape instructions.

[0075] In one embodiment of the present disclosure, the fire monitoring system further includes: a sprinkler module 18 and a spray module 19;

[0076] The spray module 18 and the spray module 19 are both connected to the second central control module 16 .

[0077] In one embodiment of the present disclosure, the spray module 18 includes: a first spray unit 181 and a second spray unit 182;

[0078] The first spray unit 181 and the second spray unit 182 are both connected to the second central control module 16;

[0079] The first spray unit 181 and the second spray unit 182 are spray units at adjacent outlets.

[0080] In one embodiment of the present disclosure, the spray module 19 includes: a first spray unit 191 and a second spray unit 192;

[0081] The first spray unit 191 and the second spray unit 192 are both connected to the second central control module 16;

[0082] The first spray unit 191 and the second spray unit 192 are spray units at adjacent outlets.

[0083] In this embodiment, the sprinkler module 18 is configured to perform spraying to extinguish fire in the target area. The sprinkler module 18 is configured to perform spraying to extinguish fire in the target area.

[0084] The first spray unit 181 is configured to spray and extinguish fire in the third area, and the first spray unit 181 is configured to spray and extinguish fire in the fourth area.

[0085] The first spray unit 191 is configured to perform spraying to extinguish fire in the third area, and the first spray unit 191 is configured to perform spraying to extinguish fire in the fourth area.

[0086] The third area and the fourth area are areas adjacent to the emergency exits. When a fire occurs, the spray module 19 is triggered by default.

[0087] The second central control module 16 is configured to control the opening and closing of the spray module 18 and the spray module 19 .

[0088] For example, there are two emergency exits on the same floor, namely emergency exit E and emergency exit F. The third area is the emergency exit E area, and the fourth area is the emergency exit F area.

[0089] Considering that spray fire extinguishing is more effective and saves more water resources, when a fire occurs, spray fire extinguishing is used first. However, spray fire extinguishing will obstruct people's vision and make it difficult to see the road ahead, and the fire extinguishing substances contained in the spray will cause certain harm to people. Therefore, when a fire occurs, the fire extinguishing method at the safety exit pointed to by the evacuation direction display module 17 is changed to spray fire extinguishing, and the fire extinguishing method for the safety exit in the other direction is still spray fire extinguishing, so as to extinguish the flames as soon as possible.

[0090] Specifically, the second central control module 16 receives "001", which means that fires have occurred at both safety exits E and F and the fire at safety exit F is greater than the fire at safety exit E. At this time, the second central control module 16 controls the first sprinkler unit 181 to turn on and the first spray unit 191 to turn off.

[0091] From the above, it can be concluded that the present disclosure controls the opening and closing of the sprinkler module 18 and the spray module 19 through the second central control module 16. When a fire occurs, the present disclosure can automatically select the optimal fire extinguishing method based on factors such as the size of the fire, the location of the emergency exit, and the evacuation of personnel. For example, when the fire is large and needs to be quickly controlled, the present disclosure will give priority to using spray fire extinguishing; when it is necessary to protect the safety of personnel, avoid obstructed vision or damage from fire extinguishing materials, spray fire extinguishing will be selected. This improves the reliability and accuracy of the fire monitoring system.

[0092] 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. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present disclosure.
