[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 alarm processing system provided by an embodiment of the present disclosure. Figure 1 , the fire alarm processing system includes:

[0040] Fire detection module 101, central control module 102, first fire extinguishing module 103, first switch module 104, temperature detection module 105, comparator 106, delay module 107, second fire extinguishing module 108 and smoke exhaust module 109;

[0041] The fire detection module 101 is connected to the central control module 102;

[0042] The central control module 102 is connected to the output end of the comparator 106, the first switch module 104, the first fire extinguishing module 103 and the smoke exhaust module 109 respectively;

[0043] The non-inverting input terminal of the comparator 106 is connected to the temperature detection module 105;

[0044] The inverting input terminal of the comparator 106 is used to receive a reference temperature value;

[0045] The output terminal of the comparator 106 is connected to the first switch module 104;

[0046] The delay module 107 is connected to the first switch module 104 and the second fire extinguishing module 108 respectively;

[0047] The first switch module 104 has a first end connected to the central control module 102 , a second end connected to the delay module 107 , and a control end controlled by the central control module 102 .

[0048] In this embodiment, the fire detection module 101 is used to sense the occurrence of a fire. It can detect fire-related signals such as smoke and flames and transmit these signals to the central control module 102. For example, the fire detection module 101 may include a smoke detector that determines whether a fire is present by detecting the concentration of smoke particles. When the smoke concentration reaches a certain threshold, a signal is sent to the central control module 102.

[0049] The central control module 102 receives signals from the fire detection module 101 and coordinates the operations of other modules. It controls the first fire extinguishing module 103 to extinguish the fire and activates the smoke exhaust module 109 to exhaust smoke. It also communicates with the first switch module 104. For example, upon receiving a fire signal from the fire detection module 101, the central control module 102 issues commands based on pre-set logic to initiate appropriate fire extinguishing and smoke exhaust measures.

[0050] The first fire extinguishing module 103 is used for extinguishing fire in the early stage of a fire and may be a water spraying fire extinguishing device, which is activated under the control of the central control module 102 to perform preliminary fire extinguishing.

[0051] Exemplarily, both the fire detection module 101 and the temperature detection module 105 monitor the environment in real time. When the fire detection module 101 detects a fire signal (e.g., smoke), it sends the signal to the central control module 102. Upon receiving the signal, the central control module 102 immediately activates the first fire extinguishing module 103 to extinguish the fire and activates the smoke exhaust module 109 to exhaust the smoke.

[0052] The first switch module 104 (such as a single-pole single-throw switch) can be switched according to the instruction of the central control module 102 to control the operation of the second fire extinguishing module 108.

[0053] The temperature detection module 105 is used to detect the ambient temperature, convert the temperature signal into an electrical signal and transmit it to the non-inverting input terminal of the comparator 106. For example, the temperature detection module 105 can be a temperature sensor that detects the temperature change of the surrounding environment in real time.

[0054] Comparator 106 receives the temperature signal from temperature detection module 105 at its non-inverting input and a reference temperature at its inverting input. When the temperature signal at the non-inverting input is greater than the reference temperature at the inverting input, comparator 106 outputs a high signal; otherwise, it outputs a low signal. These output signals control the state of first switch module 104. For example, if the reference temperature is set to 70°C and temperature detection module 105 detects a temperature of 80°C, comparator 106 will output a high signal.

[0055] When the comparator 106 outputs a high level, the central control module 102 sends a closing instruction to the first switch module 104, and the first switch module 104 switches to a state of connection with the delay module 107, and the delay module 107 starts to work. That is, the delay module 107 can trigger the second fire extinguishing module 108 to extinguish the fire after a certain delay.

[0056] The second fire extinguishing module 108 is usually a fire extinguishing device that is activated when the fire develops to a certain extent or after a delay.

[0057] For example, when a fire occurs in area A at the initial stage, the fire is small and will not spread to area B. The temperature detected by the temperature detection module 105 is lower than the reference temperature value, the comparator 106 outputs a low-level signal, and the central control module 102 sends a disconnect instruction to the first switch module 104 (that is, it is in a waiting state). At this time, the central control module 102 only starts the first fire extinguishing module 103 to extinguish the fire; when the fire in area A has occurred for a period of time, the fire is larger and begins to spread to area B. The temperature detected by the temperature detection module 105 is higher than the reference temperature value, the comparator 106 outputs a high-level signal, and the central control module 102 sends a closing instruction to the first switch module 104. At this time, while starting the first fire extinguishing module 103, the second fire extinguishing module 108 is started after the delay module 107 to extinguish the fire.

[0058] The smoke exhaust module 109 is used to exhaust the smoke generated by the fire, improve the on-site environment, and provide better conditions for personnel evacuation and fire fighting. It can be an exhaust fan or other equipment, which is turned on under the control of the central control module 102 to exhaust the smoke to the outside.

[0059] As can be seen from the above, this embodiment achieves timely detection and response to fires through the mutual cooperation of fire detection module 101 and central control module 102. The combination of temperature detection module 105 and comparator 106 can accurately determine whether the ambient temperature exceeds the safety threshold, effectively avoiding false alarms or missed alarms. The first fire extinguishing module 103 is immediately activated after the fire is confirmed to initially control the fire, while the delay module 107 and the second fire extinguishing module 108 cooperate to provide subsequent fire extinguishing support to ensure that the fire is fully controlled. Therefore, this embodiment can improve the effectiveness of the coordinated control of the fire alarm processing area and enhance the level of automation.

[0060] In one embodiment of the present disclosure, reference Figure 2 , the fire alarm processing system further includes a second switch module 110, an alarm module 111 and an alarm button 112;

[0061] The second switch module 110 is connected to the central control module 102 , the alarm module 111 and the alarm button 112 respectively.

[0062] In this embodiment, the second switch module 110 can determine whether to transmit a signal to the alarm module 111 according to the triggering condition of the alarm button 112 or the instruction of the central control module 102, thereby controlling the opening and closing of the alarm function.

[0063] The alarm module 111 is configured to issue an alarm signal. Upon receiving the on signal from the second switch module 110, the alarm module 111 activates the alarm function, dials the fire alarm number, and issues an audible and visual alarm signal to alert personnel to the fire. The alarm signal can be a loud alarm, a flashing light, or both. For example, in some locations, the alarm module 111 may emit a high-decibel beep accompanied by a flashing red light to attract attention.

[0064] Alarm button 112 is a manually triggered device. Upon discovering a fire, personnel can press alarm button 112. Pressing alarm button 112 sends a closing signal to second switch module 110, which triggers alarm module 111 to sound an alarm. Alarm button 112 can be installed in prominent locations within a building, such as hallways and stairwells, to facilitate quick access in emergencies.

[0065] Under normal circumstances, the second switch module 110 is in a standby state. If the central control module 102 receives a fire signal from the fire detection module 101 and, after certain logical judgment (for example, the system determines that the fire situation requires additional alarm notification), the central control module 102 can send a closing signal to the second switch module 110, prompting the second switch module 110 to transmit a conducting signal to the alarm module 111, thereby activating the alarm function.

[0066] At the same time, when a person discovers a fire and presses the alarm button 112, the alarm button 112 will trigger a closing signal to the second switch module 110. After the second switch module 110 receives the closing signal, the central control module 102 will immediately transmit a conduction signal to the alarm module 111, causing the alarm module 111 to sound an alarm.

[0067] From the above, it can be concluded that this implementation adopts a combination of automatic alarm and manual alarm to achieve fast and accurate alarm output, improve the efficiency and reliability of fire emergency response, and further ensure personnel safety.

[0068] In one embodiment of the present disclosure, reference Figure 2 , the fire detection module 101 includes a smoke detector 201, a temperature detector 202 and a light detector 203;

[0069] The smoke detector 201 , the temperature detector 202 and the light detector 203 are all connected to the central control module 102 .

[0070] In this embodiment, the smoke detector 201 can detect fires by detecting smoke particles in the air. When a fire occurs, smoke generated by the combustion will enter the smoke detector 201. The smoke detector 201 can detect fires in their early stages, before visible flames or high temperatures appear. This is because smoke from a fire often appears before flames and high temperatures, making it a very important early warning.

[0071] The temperature detector 202 detects changes in ambient temperature. The photodetector 203, also known as a flame detector, is sensitive to ultraviolet or infrared radiation from flames. When ultraviolet or infrared radiation from a flame reaches the detection area of ​​the photodetector 203, the detector's photosensitive element (such as a photodiode) receives the radiation signal. For example, in the case of an ultraviolet flame detector, an alarm is triggered when the ultraviolet intensity reaches the detector's threshold. The photodetector 203 reacts quickly to fires that can produce an open flame, especially in environments with strong light interference. It can distinguish flames from other light sources using a specific wavelength range, effectively avoiding false alarms.

[0072] The smoke detector 201 , the temperature detector 202 and the light detector 203 transmit their detected signals to the central control module 102 .

[0073] When the smoke detector 201 detects that the smoke concentration reaches the alarm threshold, it will send a smoke alarm signal to the central control module 102. After receiving the above signal, the central control module 102 will process it according to the preset logic, such as activating the fire extinguishing system and the smoke exhaust system, and at the same time, it can issue an alarm to notify personnel.

[0074] Similarly, when the temperature detector 202 detects a temperature anomaly (whether the temperature reaches a fixed value or the temperature change rate is abnormal) or the light detector 203 detects flame radiation, a corresponding alarm signal will be sent to the central control module 102. The central control module 102 will make a comprehensive judgment on these signals.

[0075] It can be concluded from the above that the cooperation between the smoke detector 201 , the temperature detector 202 , the light detector 203 and the central control module 102 can improve the accuracy of fire alarm and the effectiveness of system response.

[0076] In one embodiment of the present disclosure, reference Figure 3 , the central control module 102 includes a comparison unit 301, a control unit 302 and a timing unit 302;

[0077] The comparison unit 301 is connected to the smoke detector 201, the temperature detector 202, the light detector 203 and the control unit 302 respectively;

[0078] The control unit 302 is connected to the first fire extinguishing module 103 and the timing unit 302 respectively;

[0079] The timing unit 302 is connected to the second switch module 110 .

[0080] In this embodiment, the comparison unit 301 receives signals from the smoke detector 201 , the temperature detector 202 , and the light detector 203 .

[0081] For example, the smoke concentration signal sent by the smoke detector 201, the temperature signal sent by the heat detector 202, and the flame radiation signal sent by the light detector 203 are all transmitted to the comparison unit 301. The comparison unit 301 has preset thresholds for different detector signals and compares the actual signal strength received with these thresholds.

[0082] If the smoke concentration signal exceeds the threshold corresponding to the smoke detector 201, or the temperature signal exceeds the threshold corresponding to the temperature detector 202, or the flame radiation signal exceeds the threshold corresponding to the light detector 203, the comparison unit 301 will determine that a fire has occurred and transmit the above signal to the control unit 302.

[0083] After receiving the fire determination signal from the comparison unit 301 , the control unit 302 first activates the first fire extinguishing module 103 to enable the first fire extinguishing module 103 to start a fire extinguishing operation.

[0084] At the same time, the control unit 302 communicates with the timing unit 302 to start the timing function of the timing unit 302.

[0085] The timing unit 302 is used to record time. When the control unit 302 starts the timing unit 302, it starts timing. The timing unit 302 can record the response time of the alarm module 111 or the alarm button 112 to determine whether the alarm module 111 has an alarm fault.

[0086] As can be seen from the above, this embodiment integrates the comparison unit 301, the control unit 302, and the timing unit 303 to integrate multi-dimensional information such as smoke, temperature, and light sensing, ensuring accurate fire detection and rapid response. The timing unit 302 not only records the response time but also monitors the status of the alarm module 111, effectively preventing failures and ensuring stable system operation.

[0087] In one embodiment of the present disclosure, reference Figure 3 , the second switch module 110 is a single-pole double-throw switch;

[0088] A single-pole double-throw switch has a first fixed end connected to the timing unit 302 , a first movable end connected to the alarm module 111 , and a second movable end connected to the alarm button 112 .

[0089] In this embodiment, the first fixed terminal of the single-pole double-throw switch receives the signal from the timing unit 302 and records the alarm response time. The first movable terminal is connected to the alarm module 111. When the switch is switched to this position, the signal is transmitted from the first fixed terminal to the alarm module 111, thereby triggering the alarm function. The alarm module 111 can dial the fire alarm number and emit audible and visual alarm signals.

[0090] The second active terminal is connected to alarm button 112, providing a way to manually trigger an alarm. In an emergency, a person can press alarm button 112, transmitting a signal via the second active terminal to the first stationary terminal, thereby triggering alarm module 111. Under normal circumstances, second switch module 110 is in a standby state, awaiting a trigger signal from alarm button 112.

[0091] It can be concluded from the above that this embodiment provides a dual alarm triggering mechanism, thereby improving the timeliness and reliability of fire alarm response.

[0092] In one embodiment of the present disclosure, reference Figure 3 , the fire alarm processing system further includes a third switch module 113;

[0093] The third switch module 113 is connected to the central control module 102;

[0094] The third switch module 113 is used to connect to the non-fire power supply 10 .

[0095] In this embodiment, the third switch module 113 can operate the non-fire power supply 10 according to the instructions of the central control module 102. The non-fire power supply 10 refers to the power supply used by other general electrical equipment in a building, except for fire protection equipment (such as fire pumps, smoke exhaust fans, etc.).

[0096] Disconnecting the non-fire power supply 10 is a crucial safety measure in the event of a fire. This is because the non-fire power supply 10 can provide energy for the spread of the fire, such as powering certain electrical devices. These devices may short-circuit, spark, or overheat during a fire, exacerbating the fire. Disconnecting the non-fire power supply 10 also prevents people from coming into contact with live equipment during evacuation and potentially suffering electric shock.

[0097] When the central control module 102 receives a fire alarm signal (from the smoke detector 201, the temperature detector 202 or the light detector 203), after being processed by the internal comparison unit 301 and the control unit 302, the central control module 102 will send an instruction to the third switch module 113 according to the preset logic.

[0098] After receiving the instruction from the central control module 102 , the third switch module 113 will immediately take action to cut off the connection with the non-fire power supply 10 .

[0099] For example, in a commercial building, when the central control module 102 determines that a fire has occurred, the third switch module 113 will cut off non-fire power supplies 10 such as lighting fixtures and ordinary electrical sockets in the mall, and only retain the power supply of fire power supplies such as fire elevators, fire water pumps, and emergency lighting to ensure the normal operation of fire-fighting equipment and the safe evacuation of personnel.

[0100] From the above, it can be concluded that the collaborative working mechanism of this embodiment can effectively prevent the fire from further worsening due to non-fire power supply 10 related equipment, while ensuring the power supply of fire fighting equipment, which is an important link of the fire alarm processing system in ensuring building fire safety.

[0101] In one embodiment of the present disclosure, reference Figure 3 , the fire alarm processing system also includes a voice broadcast module 114;

[0102] The voice broadcast module 114 is connected to the central control module 102 .

[0103] In this embodiment, the voice broadcast module 114 can convey emergency information to people through clear voice broadcast. Compared with traditional sound and light alarms, voice broadcast can more specifically inform people of important contents such as the fire situation, evacuation direction and precautions.

[0104] In emergency situations such as fires, people may panic and become overwhelmed. The voice announcement module 114 can use concise and clear language to guide people to take corrective actions, such as "Attention, there is a fire in this building. Please remain calm and evacuate quickly according to the evacuation signs." This improves people's emergency response efficiency and reduces confusion and panic.

[0105] When the central control module 102 receives the fire signal from the fire detection module 101, it will immediately process the signal and determine whether it is necessary to activate the voice broadcast module 114. If the fire situation is serious or specific instructions need to be conveyed to people, the central control module 102 will send a start signal to the voice broadcast module 114.

[0106] Upon receiving a start signal from the central control module 102, the voice announcement module 114 begins playing pre-recorded audio content. This content can be customized to suit different locations and needs. For example, in a school, the announcement could remind students not to panic and to evacuate in an orderly manner according to the teacher's instructions. In a shopping mall, the announcement could inform customers of the location of evacuation routes and precautions. Furthermore, the announcement module 114 can be updated based on real-time information transmitted from the central control module 102. For example, if the fire expands or new dangerous situations emerge, the announcement content can be adjusted to alert people.

[0107] After a fire occurs, the voice broadcast module 114 can not only help people quickly understand the fire situation and take corrective action, but also provide assistance to rescuers. For example, the voice broadcast can inform rescuers of the specific situation at the fire scene, such as whether there are people trapped, the size of the fire, and the direction of spread, so that rescuers can formulate more effective rescue plans.

[0108] From the above, it can be concluded that the voice broadcast module 114 can convey fire information in a timely and clear manner, reminding personnel to take countermeasures quickly, effectively avoiding delays caused by visual impairment or panic, and providing strong support for personnel evacuation and initial fire fighting.

[0109] In one embodiment of the present disclosure, reference Figure 3 , the fire alarm processing system also includes a hybrid network 115 and a remote monitoring terminal 116;

[0110] The central control module 102 is connected to the remote monitoring terminal 116 via a hybrid network 115 .

[0111] In this embodiment, the hybrid network 115 combines multiple communication technologies, such as wired network, wireless network, Bluetooth, etc., to provide a stable, reliable and flexible connection method between the central control module 102 and the remote monitoring terminal 116.

[0112] For example, if one communication method fails, the system can automatically switch to another available communication method to ensure that the connection between the central control module 102 and the remote monitoring terminal 116 is not interrupted. For example, if a wired network fails, the system can automatically switch to a wireless network to ensure that fire alarm information can be transmitted to the remote monitoring terminal 116 in a timely manner.

[0113] The remote monitoring terminal 116 can be a computer system in a monitoring center or an application on a mobile device. Through the connection with the central control module 102, the remote monitoring terminal 116 can receive various information from the fire alarm processing system in real time, including the status of fire detectors, the operation of fire extinguishing equipment, smoke concentration, temperature, etc.

[0114] Remote monitoring terminal 116 not only receives information but also remotely controls the fire alarm processing system. For example, upon receiving a fire alarm signal, remote monitoring personnel can send instructions to central control module 102 via remote monitoring terminal 116 to activate or deactivate specific fire extinguishing equipment, smoke exhaust systems, and so on. This remote control function enables rapid response in emergency situations, improving firefighting and rescue efficiency.

[0115] The central control module 102 establishes a connection with the remote monitoring terminal 116 via the hybrid network 115. When the central control module 102 receives a fire alarm signal, it processes the signal and sends it to the remote monitoring terminal 116 via the hybrid network 115. After receiving the signal, the remote monitoring terminal 116 displays and processes it accordingly and can send feedback instructions to the central control module 102 as needed.

[0116] As can be seen from the above, diverse networking methods can adapt to different environments and needs, ensuring efficient data transmission in a variety of complex situations. At the same time, two-way communication connections enable remote monitoring personnel to obtain timely information on fire conditions and effectively control and manage the fire alarm processing system.

[0117] 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.
