Abstract
Description
A smart fire alarm control system, method, device, and readable storage medium Technical Field
[0001] This application belongs to the field of fire alarm technology, specifically relating to a smart fire alarm control system, method, device, and readable storage medium. Background Technology
[0002] For fires occurring in residential locations and other places (such as hotels, restaurants, cultural and entertainment venues, and large complexes), existing fire alarm technologies typically use a combination of personnel detection and fire detection for alarm control. The control principle is as follows: if a fire occurs when no one is present, the fire alarm system needs to sound an alarm to notify relevant personnel to handle the fire situation promptly; if people are present, artificially generated smoke or fire usually does not require an alarm, and if smoke remains after people have left the location, an alarm is also usually not required. For example, the applicant's prior patent, patent number ZL 202210640095.8, entitled "A Smart Fire Alarm and Rescue System," controls whether to send out an alarm signal by considering whether people are present in the residential area and the state of smoke or fire.
[0003] However, in the aforementioned existing technologies, for situations where smoke remains after people have left the premises following a man-made fire, a fire detection device (or a type of fire detection device), namely a high-sensitivity smoke detector T1 (which can only detect smoke), controls another fire detection device (or a different type of fire detection device), namely an integrated module TYKF11 of a high-sensitivity fire detector and a remote control transmitter (TYKF11 can be a visual smoke detector, or a visual open flame detector, or a visual smoke and open flame detector, or a smoke detector, or an aspirating smoke detector, or a flame detector, or a heat detector, or a composite fire detection method, etc., to achieve fire detection). When T1 detects smoke, TYKF11 is in a power-off state and does not perform fire detection control. When T1 does not detect smoke, TYKF11 is in fire detection control state. However, because the fire signals detected by the two are asynchronous and / or have different frequencies, T1 may delay control or fail to control TYKF11. For example, if TYKF11 detects smoke or fire signal before T1, it will perform fire detection control alarm. Therefore, the above-mentioned existing technology will still lead to equipment failure and / or false alarms. It cannot effectively solve the problem of false alarms caused by the presence of harmless (smoke) fire characteristics left by people after they leave the place.
[0004] In addition, in existing technologies, personnel detectors are always in a detection state, regardless of whether there is smoke or fire. At the same time, as long as the personnel detector detects a person, it will activate the corresponding detection control module, resulting in ineffective and frequent activation, which causes energy consumption and mechanical wear, affecting its service life and economy. Summary of the Invention
[0005] To address the false alarm problem in existing technologies, this application proposes a smart fire alarm control system, method, device, and readable storage medium. This application can trigger a fire alarm when there is no one around and a fire is burning, but not when there are people around and a fire is burning. It also does not trigger an alarm if smoke or fire is generated by human intervention, or if harmless smoke or fire characteristics remain after people have left the premises. This avoids false alarms and improves the reliability and accuracy of fire alarms.
[0006] Firstly, this application achieves its purpose through the following technical solution:
[0007] A smart fire alarm control system, the control system comprising:
[0008] A fire detection and control module is used to detect fire signals and outputs a first control signal to the controller when a fire is detected.
[0009] A personnel detection control module is used to detect personnel signals, and when a personnel is detected, it outputs a second control signal to the controller.
[0010] And, a controller, the controller being used to implement:
[0011] When both the first control signal and the second control signal are received simultaneously, no alarm control signal is output.
[0012] If the first control signal is received but the second control signal is not received, and the situation is that the fire was caused by human activity and people left, then no alarm control signal will be output; otherwise, an alarm control signal will be output to sound an alarm.
[0013] In some implementations, the personnel detection control module is activated by the fire detection control module. The personnel detection control module is activated only when the fire detection control module detects a fire signal; otherwise, the personnel detection control module is in standby mode.
[0014] In some implementations, the controller includes:
[0015] The second control unit has its control terminal D connected to the output terminal of the personnel detection control module, its input terminal E connected to the output terminal of the fire detection control module, and its output terminal F connected to the control terminal G of the third control unit. When the control terminal D of the second control unit receives the second control signal, it controls the input terminal E and the output terminal F to be connected. When the control terminal D of the second control unit does not receive the second control signal, the input terminal E and the output terminal F are disconnected.
[0016] In addition, there is a third control unit, wherein the control terminal G of the third control unit is connected to the output terminal F of the second control unit, the input terminal H of the third control unit is connected to the output terminal of the fire detection control module, the first output terminal I of the third control unit is connected to the control terminal G of the third control unit, and the second output terminal J of the third control unit is connected to the fire remote control transmitter; wherein, when the control terminal G of the third control unit does not receive a signal, the input terminal H of the third control unit is connected to the second output terminal J; when the control terminal G of the third control unit receives a signal, the input terminal H of the third control unit is connected to the first output terminal I.
[0017] In some implementations, the controller further includes:
[0018] The first control unit has its control terminal A connected to the output terminal of the fire detection control module. The first switch terminal B and the second switch terminal C of the first control unit serve as power switches for the personnel detection control module 2. When the control terminal A of the first control unit receives a signal, the first switch terminal B and the second switch terminal C are closed under the control of the control terminal A, and the personnel detection control module is activated. When the control terminal A of the first control unit does not receive a signal, the first switch terminal B and the second switch terminal C are open, and the personnel detection control module is in standby mode.
[0019] In some implementations, the first control unit, and / or the second control unit, and / or the third control unit employs an electromagnetic relay.
[0020] In some implementations, the controller is configured to execute the following program:
[0021] The first and second control signals received are stored in sequence.
[0022] If the first control signal and the second control signal are received simultaneously at the current moment, no alarm control signal will be output.
[0023] If the first control signal is received at the current moment, but the second control signal is not received, and the most recent historical moment is when both the first and second control signals are received simultaneously, then no alarm control signal is output; otherwise, an alarm control signal is output to trigger an alarm.
[0024] In some implementations, the fire detection control module employs image detection, and / or smoke detection, and / or aspirating smoke detection, and / or flame detection, and / or temperature detection, and / or a combination of fire detection methods to achieve fire detection.
[0025] In some implementations, the personnel detection control module employs image detection, and / or radar detection, and / or infrared detection, and / or Bluetooth technology, and / or a combination of personnel detection methods to achieve personnel detection.
[0026] Secondly, this application proposes a smart fire alarm control method, the control method comprising:
[0027] The system receives signals from the fire detection control module and the personnel detection control module in real time; wherein, the fire detection control module is used to detect fire signals and outputs a first control signal when a fire is detected; the personnel detection control module is used to detect personnel signals and outputs a second control signal when personnel are detected.
[0028] When the first control signal and the second control signal are received simultaneously, no alarm control signal is output.
[0029] When the first control signal is received but the second control signal is not received, and if the fire is caused by human activity and people have left, no alarm control signal is output; otherwise, an alarm control signal is output to sound an alarm.
[0030] In some embodiments, the control method further includes:
[0031] When the first control signal is received, the personnel detection control module is activated; otherwise, the personnel detection control module is in standby mode.
[0032] In some embodiments, the control method further includes:
[0033] The first and second control signals received are stored in sequence.
[0034] If the first control signal and the second control signal are received simultaneously at the current moment, no alarm control signal will be output.
[0035] If the first control signal is received at the current moment, but the second control signal is not received, and the most recent historical moment is when both the first and second control signals are received simultaneously, then no alarm control signal is output; otherwise, an alarm control signal is output to trigger an alarm.
[0036] Thirdly, this application proposes a computer device including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the above-described method.
[0037] Fourthly, this application proposes a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the above-described method.
[0038] This application proposes a smart fire alarm control system, method, device, and readable storage medium that can trigger an alarm when there is no one and a fire, but not when there are people and a fire, and also not when harmless smoke remains after people have left the premises after the fire is started by human intervention. This avoids the risk of false alarms and improves the reliability and accuracy of fire alarms. This application uses only one fire detection device to detect fire signals, and there is no problem of false alarms caused by the fire signals detected by two fire detection devices being out of sync and / or having different frequencies. This effectively solves the defects existing in the prior art.
[0039] This application proposes a smart fire alarm control system, method, device, and readable storage medium. The fire detection control module controls the activation of the personnel detection control module. That is, the personnel detection control module is activated only when there are fire characteristics, and remains in standby mode when there are no fire characteristics. This can save energy, reduce mechanical wear of the personnel detection control module, and improve the service life and economy of the device.
[0040] The present application proposes a fire intelligent alarm control system, method, device and readable storage medium, which is simple to implement. It only requires a fire detection control module, a personnel detection control module and simple control logic to achieve accurate and reliable fire alarm control. It is low-cost, low-energy consumption and easy to apply in large-scale engineering. Attached Figure Description

For example, the above terms do not limit the order and / or importance of the elements. The above terms are only used for the purpose of distinguishing one element from other elements.

For example, without departing from the scope of the various embodiments of this application, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.
[0051] It should be noted that if a description is made of "connecting" one component to another, then the first component can be directly connected to the second component, and a third component can be "connected" between the first and second components. Conversely, when a component is "directly connected" to another component, it can be understood that there is no third component between the first and second components.
[0052] The terminology used in the various embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the various embodiments of this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of this application pertain. The terms (such as those defined in a generally used dictionary) are to be interpreted as having the same meaning as in the context of the relevant technical field and are not to be interpreted as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.
[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.
[0054] Example 1: Existing fire alarm technologies address situations where harmless smoke remains after people have left the premises following a man-made fire. This is achieved by having one fire detection device control another, thus preventing alarm activation when this occurs. However, due to asynchrony and / or frequency discrepancies in the detected fire signals, equipment malfunctions and / or false alarms can still occur. This fails to effectively solve the problem of false alarms occurring when harmless smoke remains after people have left the premises. To address this, this example proposes a smart fire alarm control system. This system alarms when there is no fire and no one is present, but does not alarm when there is fire and people are present. It also does not alarm when people have left the premises after a man-made fire, thus avoiding false alarms and improving reliability.
[0055] As shown in Figure 1, the control system proposed in this embodiment includes:
[0056] Fire detection and control module 1, which is used to detect fire signals and outputs a first control signal to the controller when a fire is detected;
[0057] Personnel detection control module 2 is used to detect personnel signals, and when a personnel is detected, it outputs a second control signal to the controller.
[0058] And, controller 10, which is used to implement:
[0059] When both the first and second control signals are received simultaneously, no alarm control signal is output.
[0060] When the first control signal is received but the second control signal is not received, if the situation is a case of smoke and fire caused by human intervention and personnel leaving (i.e., a fire with harmless smoke and fire characteristics remaining after personnel leave the location), no alarm control signal will be output; otherwise, an alarm control signal will be output to trigger an alarm.
[0061] The control system proposed in this embodiment alarms when there is a fire but no one is present, and does not alarm when there is a fire but people are present. Even if harmless smoke remains after people have left the location, the fire characteristics are considered as if people are present, and no alarm is triggered. This avoids false alarms and further improves the accuracy and reliability of fire alarms. At the same time, this embodiment uses only one fire detection device to detect fire signals, so there is no problem of false alarms caused by asynchronous and / or different frequencies of fire signals detected by two fire detection devices. This effectively solves the defects existing in the prior art.
[0062] Furthermore, the control system proposed in this embodiment also includes:
[0063] The fire remote control transmitter 6, when receiving the alarm control signal sent by the controller 10, transmits a fire alarm signal to trigger a fire alarm.
[0064] Furthermore, considering that the personnel detection control module will be in working condition as long as it detects personnel, regardless of whether there is a fire or not, frequent invalid starts cause energy consumption and mechanical wear of the components, thus affecting the service life and economy of the components. To address this, in the control system proposed in this embodiment, the personnel detection control module 2 is controlled by the fire detection control module 1. That is, the personnel detection control module 2 is only activated when the fire detection control module 1 detects a fire signal; at other times, the personnel detection control module 2 is in standby mode, thereby saving energy, reducing mechanical wear, and improving the service life and economy of the components.
[0065] Furthermore, based on the same technical concept described above, this embodiment also proposes a smart fire alarm control method, as shown in Figure 2. The control method proposed in this embodiment includes:
[0066] The system receives signals from the fire detection control module and the personnel detection control module in real time. The fire detection control module is used to detect fire signals and outputs a first control signal when a fire is detected. The personnel detection control module is used to detect personnel signals and outputs a second control signal when a person is detected.
[0067] When both the first and second control signals are received simultaneously, no alarm control signal is output.
[0068] When the first control signal is received but the second control signal is not received, and if the fire is caused by human activity and personnel have left, no alarm control signal will be output; otherwise, an alarm control signal will be output to sound an alarm.
[0069] Furthermore, the control method proposed in this embodiment also includes:
[0070] Upon receiving the first control signal, the personnel detection control module is activated; otherwise, the personnel detection control module remains in standby mode.
[0071] Furthermore, the aforementioned fire detection and control module can employ image detection (e.g., visual smoke detection, and / or visual open flame detection, and / or visual smoke and open flame detection), and / or smoke detection, and / or aspirating smoke detection, and / or flame detection, and / or heat detection, and / or composite fire detection methods to achieve fire detection.
[0072] Furthermore, the personnel detection control module can employ image detection, and / or radar detection, and / or infrared detection, and / or Bluetooth technology, and / or composite personnel detection methods to achieve personnel detection.
[0073] Example 2: This example further describes the design of the controller 10 in Example 1, as shown in Figure 3. The controller 10 in this example includes:
[0074] The second control unit 4 has its control terminal D connected to the output terminal of the personnel detection control module 2, its input terminal E connected to the output terminal of the fire detection control module 1, and its output terminal F connected to the control terminal G of the third control unit 5. The connection between the input terminal E and the output terminal F of the second control unit 4 is controlled by the control terminal D. When the control terminal D receives the second control signal, the input terminal E and the output terminal F are connected, and the first control signal input by the input terminal E can be output to the third control unit 5. When the control terminal D does not receive the second control signal, the input terminal E and the output terminal F are disconnected, and the first control signal input by the input terminal E cannot be output to the third control unit 5.
[0075] Furthermore, the third control unit 5 has its control terminal G connected to the output terminal F of the second control unit 4, its input terminal H connected to the output terminal of the fire detection control module 1, its first output terminal I connected to the control terminal G, and its second output terminal J connected to the fire remote control transmitter 6. The conduction relationship between the input terminal H of the third control unit 5 and the first output terminal I and the second output terminal J is controlled by the control terminal G. If the control terminal G of the third control unit 5 receives the first control signal output from the output terminal F of the second control unit 4, the input terminal H of the third control unit 5 is connected to the first output terminal I until the fire detection control module 1 no longer detects smoke signals, at which point the input terminal H of the third control unit 5 returns to being connected to the second output terminal J.
[0076] The working principle of the controller 10 proposed in this embodiment is as follows:
[0077] When there is no fire or no fire, or when there is fire but no fire, the fire detection and control module 1 does not detect a fire signal. At this time, the input terminal H of the third control unit 5 is connected to the second output terminal J, and no alarm is triggered.
[0078] When there is no one and a fire (i.e., a real fire occurs), the fire detection control module 1 detects the fire signal. At this time, the fire detection control module 1 outputs the first control signal to the input terminal E of the second control unit 4 and the input terminal H of the third control unit 5. If the personnel detection control module 2 does not detect anyone, that is, the personnel detection control module 2 does not output the second control signal to the control terminal D of the second control unit 4, the control terminal D does not perform control, the input terminal E and the output terminal F are disconnected, the control terminal G does not perform control, then the input terminal H of the third control unit 5 is connected to the second output terminal J, and an alarm signal is emitted through the fire remote control transmitter to trigger an alarm, thus realizing fire alarm in the case of no one and a fire.
[0079] When a fire is started by someone but not by anyone (i.e., a fire with harmless smoke remaining after someone leaves the location is considered as if someone is present), the fire detection control module 1 detects a fire signal and outputs a first control signal to the input terminal E of the second control unit 4 and the input terminal H of the third control unit 5. If the personnel detection control module 2 simultaneously detects someone, it outputs a second control signal to the control terminal D of the second control unit 4. Input terminal E and output terminal F are connected. The first control signal is output through output terminal F to the control terminal G of the third control unit 5. This controls the input terminal H of the third control unit 5 to switch to be connected to the first output terminal I, and disconnects the input terminal H from the second output terminal J. The first output terminal I of the third control unit 5 returns the received first control signal to the control terminal G of the third control unit 5, thus... The input terminal H of the third control unit 5 is always connected to the first output terminal I. If personnel need to leave the premises and there are still harmless fire characteristics in the premises, the personnel detection module 2 will no longer detect anyone after the personnel leave the premises. That is, the personnel detection control module 2 will no longer output the second control signal to the control terminal D of the second control unit 4. The control terminal D will no longer perform control, and the input terminal E and the output terminal F will be disconnected. At this time, the control terminal G of the third control unit 5 will receive the first control signal output by the first output terminal I and continue to perform closed-loop control until the fire detection control module 1 no longer detects the fire signal and no longer outputs the first control signal. That is, the input terminal H can be restored to being connected to the second output terminal J. During this stage, no alarm will be triggered. That is, no alarm will be triggered when there is fire and people are present, or when there is fire but no people are present (the fire characteristics of harmless fire left behind after personnel leave the premises due to human-caused smoke are regarded as people being present).
[0080] Furthermore, the second control unit 4 and the third control unit 5 in this embodiment can be implemented using, but are not limited to, electromagnetic relays. The working principle of the electromagnetic relay is as follows: when the control terminal receives a signal, it generates electromagnetic induction, controlling the switching of the switching plates to achieve conduction of different lines.
[0081] Example 3: This example further optimizes the controller 10 of Example 2, as shown in Figure 4. The controller 10 in this example includes:
[0082] The first control unit 3 has its control terminal A connected to the output terminal of the fire detection control module 1. The first switch terminal B and the second switch terminal C of the first control unit 3 act as power switches for the personnel detection control module 2, controlling the on / off state of the positive or negative power supply of the personnel detection control module 2. When the control terminal A receives the first control signal, the first switch terminal B and the second switch terminal C are closed under the control of the control terminal A, and the personnel detection control module 2 starts working. When the control terminal A does not receive the first control signal, the first switch terminal B and the second switch terminal C are open, and the personnel detection control module 2 is in standby mode. This ensures that the personnel detection control module 2 is only activated when a fire signal is present, and remains in standby mode at other times, reducing energy consumption, mechanical wear, and extending the service life of the device.
[0083] The structure and connection relationship of the second control unit 4 and the third control unit 5 are as shown in Embodiment 2 above, and will not be described in detail here.
[0084] The working principle of the controller 10 proposed in this embodiment is as follows:
[0085] When the fire detection control module 1 does not detect a fire signal, the power switch of the personnel detection control module 2 is turned off (i.e., the first switch terminal B and the second switch terminal C of the first control unit 3 are turned off), thereby disconnecting the positive or negative power supply of the personnel detection control module 2, and the personnel detection control module 2 is in standby mode.
[0086] When the fire detection control module 1 detects a fire signal, it outputs a first control signal to the control terminal A of the first control unit 3, the input terminal E of the second control unit 4, and the input terminal H of the third control unit 5. At this time, the control terminal A of the first control unit 3 controls the energization switch of the personnel detection control module 2 to close (i.e., the first switch terminal B and the second switch terminal C of the first control unit 3 are closed), thereby closing the positive or negative power supply of the personnel detection control module 2, causing the personnel detection control module 2 to start and perform personnel detection. This ensures that the personnel detection control module 2 only starts when a fire signal is present, and remains in standby mode at other times, reducing energy consumption, mechanical wear, and extending the service life of the device. Other control principles are as described in Embodiment 2 above, and will not be elaborated further here.
[0087] Furthermore, the first control unit 3 in this embodiment may employ, but is not limited to, an electromagnetic relay. The working principle of the electromagnetic relay is as follows: when the control terminal receives a signal, it generates electromagnetic induction, controlling the switching of the switch plates to achieve the conduction of different lines.
[0088] Example 4: This example further describes the design of the controller 10 in Example 1. Compared to the hardware circuit implementation in Examples 2 and 3, the controller 10 in this example is implemented in software. The controller 10 in this example is configured to perform the following steps:
[0089] The first and second control signals received are stored sequentially.
[0090] If the first control signal and the second control signal are received simultaneously at the current moment, no alarm control signal will be output.
[0091] If the first control signal is received but the second control signal is not received at the current moment, and the most recent historical moment is when both the first and second control signals are received simultaneously, no alarm control signal will be output; otherwise, an alarm control signal will be output to trigger an alarm.
[0092] Furthermore, the controller proposed in this embodiment is also configured to perform the following steps:
[0093] Upon receiving the first control signal, the personnel detection control module 2 is activated; otherwise, the personnel detection control module 2 remains in standby mode.
[0094] Compared to the hardware implementation methods of Embodiments 2 and 3, this embodiment uses software to achieve fast and accurate alarm control, which does not require a large number of supporting hardware components and reduces hardware costs.
[0095] As can be seen from the above embodiments, the intelligent fire alarm control system proposed in this application can realize fire alarm when there is a fire but no one is there, and fire alarm when there is a fire but no one is there, and fire alarm when there is a fire but no one is there, and fire alarm when there is smoke or fire caused by human intervention and people leave the place but there are still fire characteristics of harmless smoke or fire, it is also regarded as fire and people are there, and no fire alarm is triggered, thereby ensuring the accuracy and reliability of fire alarm, and effectively solving the defects existing in the prior art. Its implementation method is simple, low cost, low energy consumption, and easy to apply in large-scale engineering.
