the second comparator 122 has a non-inverting input connected to the second flame detection module 11, an inverting input for receiving the first reference flame signal, and an output connected to the first central control module 13.
In one embodiment of the present disclosure, the switch module 14 includes a first switch 141 and a second switch 142;
The first switch 141 has a first end connected to the first flame detection module 10, a second end connected to the second comparator module 15, and a control end connected to the first central control module 13;
The first end of the second switch 142 is connected with the second flame detection module 11, the second end is connected with the second comparator module 15, and the control end is connected with the first central control module 13;
the first switch 141 and the second switch 142 are normally open switches.
In one embodiment of the present disclosure, the second comparator module 15 is a cascaded comparator module;
The second comparator module 15 is configured to send the comparison result to the second central control module 16.
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;
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;
the first and second evacuation direction display units 172 are evacuation direction display units at adjacent exits.
In the present 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, and 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.
The first central control module 13 is configured to receive a "1", and then control the first switch 141 to close and the second switch 142 to close.
The second comparator module 15 is a cascade 74LS38 comparator module, and can output three signals of "100", "010" and "001", and corresponds to the infrared radiation value detected by the first flame detection module 10 being 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 being 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 being less than the infrared radiation value detected by the second flame detection module 11, respectively.
The first evacuation direction display unit 171 and the second evacuation direction display unit 172 are each configured to display the direction of the nearest safety exit from the current position. The first evacuation direction display unit 171 and the second evacuation direction display unit 172 are arranged around the adjacent safety exits.
The second central control module 16 is configured to receive the signal transmitted by the second comparator module 15 and control the orientations of the first evacuation direction display unit 171 and the second evacuation direction display unit 172.
For example, there are two exits at the same floor, an exit C and an exit D, respectively, the first evacuation direction display unit 171 is near the exit C, and the second evacuation direction display unit 172 is near the exit D. The predetermined first reference flame signal is 65 milliwatts per square centimeter, the first flame detection module 10 detects an infrared radiation value of 70 milliwatts per square centimeter at the safety outlet C and sends it to the first comparator 121, and the second flame detection module 11 detects an infrared radiation value of 85 milliwatts per square centimeter at the safety outlet D 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 a "1" to the first central control module 13, and since 85 milliwatts per square centimeter is greater than 65 milliwatts per square centimeter, the first comparator 121 sends a "1" to the first central control module 13, at which time the first central control module 13 receives two "1" s, controls the first switch 141 and the second switch 142 to close, at which time the first flame detection module 10 sends the detected infrared radiation value to the second comparator module 15, the second flame detection module 11 sends the detected infrared radiation value to the second comparator module 15, and the second comparator module 15 compares the two, and since 85 milliwatts per square centimeter is greater than 65 milliwatts per square centimeter, sends a "001" to the second central control module 16, that is, the fire at the safety exit D is greater than the fire at the safety exit C, controls the directions displayed by the first evacuation direction display unit 171 and the second direction display unit 172 to both point to the safety exit C.
Even if a fire occurs at the safety exit C at a distance from the first evacuation direction display unit 171, since there are only two safety exits at this layer 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 is still directed toward the safety exit C.
Even if the second evacuation direction display unit 172 is relatively close to the safety exit D, since the fire is greater than that of the safety exit C, the direction of display of the second evacuation direction display unit 172 is directed toward the safety exit C.
Or for example, after a 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, 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 at the safety exit C and the safety exit D are equal in size, at which time the second central control module 16 controls the directions 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.
It can be derived from the above that, when the present disclosure detects a fire, the first central control module 13 can control the switch module 14 to be closed according to the output of the comparator, and then transmit the data of the flame detection module to the second comparator module 15 for further comparison. The present disclosure can intuitively indicate an optimal evacuation path through the first evacuation direction display unit 171 and the second evacuation direction display unit 172, and helps to quickly guide people to evacuate in an emergency, reducing panic and confusion. The present disclosure is capable of handling a variety of fire conditions, including a single safety vent fire, both safety vents fire but with different fires, etc. According to the fire escape indication system, the data of the two flame detection modules are compared, the safety exit with smaller fire can be intelligently selected as an escape path, or people are indicated to evacuate to the nearest safety exit when the fire is equal, so that the reliability and the accuracy of the fire escape indication are improved.
In one embodiment of the present disclosure, the fire monitoring system further comprises a spray module 18 and a spray module 19;
The spray module 18 and the spray module 19 are both connected to the second central control module 16.
In one embodiment of the present disclosure, the spray module 18 includes a first spray unit 181 and a second spray unit 182;
The first spraying unit 181 and the second spraying unit 182 are both connected with the second central control module 16;
The first spraying unit 181 and the second spraying unit 182 are spraying units at adjacent outlets.
In one embodiment of the present disclosure, spray module 19 includes a first spray unit 191 and a second spray unit 192;
the first spraying unit 191 and the second spraying unit 192 are connected with the second central control module 16;

The first spraying unit 191 is configured to spray fire-extinguish the third area, and the first spraying unit 191 is configured to spray fire-extinguish the fourth area.
The third and fourth zones are zones adjacent the safety exit and default to trigger the spray module 19 when a fire occurs.
The second central control module 16 is configured to control the opening and closing of the spray modules 18 and 19.
For example, there are two safety exits on the same floor, namely safety exit E and safety exit F, respectively, the third zone being the safety exit E zone and the fourth zone being the safety exit F zone.
Considering that the effect of spray fire extinguishing is better and comparatively saving water resource, so when the conflagration takes place, the preferred use spray fire extinguishing mode, but spray fire extinguishing can lead to personnel's sight to be blocked, be difficult to see the place ahead road, and contain the fire extinguishing substance in the spray and can cause certain injury to the person, so when the conflagration takes place, the fire extinguishing mode of the directional safety exit of evacuation direction display module 17 demonstration direction changes spray fire extinguishing, the fire extinguishing mode of the safety exit of another direction still is spray fire extinguishing, in order to put out the fire as early as possible.
Specifically, the second central control module 16 receives "001", that is, the fire disaster occurs at both the safety exit E and the safety exit F, and the fire disaster at the safety exit F is greater than the fire disaster at the safety exit E, at this time, the second central control module 16 controls the first spraying unit 181 to be turned on and the first spraying unit 191 to be turned off.
From the above, the present disclosure controls the opening and closing of the spray module 18 and the spray module 19 through the second central control module 16. When a fire disaster occurs, the fire extinguishing system can automatically select an optimal fire extinguishing mode according to factors such as fire intensity, safety exit position, personnel evacuation condition and the like. For example, in situations where the fire is large and rapid control is required, the present disclosure may prefer to use spray to extinguish the fire, while in situations where personnel safety is required, sight obstruction or fire extinguishing substance injury is avoided, spray to extinguish the fire is selected. The reliability and the accuracy of the fire control monitoring system are improved
