Technical Field
[0001] This utility model belongs to the field of window breaker technology, and in particular relates to an automatic fire-fighting window breaking system. Background Technology
[0002] In automatic window-breaking systems for fire protection, sensors are typically used to detect changes in the environment. When a change in environmental parameters is detected, the automatic window-breaking system is activated to open the emergency escape route.
[0003] However, in existing technologies, sensor detection may be subject to bias and error, causing the automatic window-breaking system to perform incorrect actions. Therefore, it is necessary to provide a fire-fighting automatic window-breaking system to solve the aforementioned problems. Utility Model Content
[0004] This utility model provides an automatic window breaking system for fire protection, which uses multiple smoke sensors for environmental detection, thereby improving the detection accuracy of the window breaking system.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic window-breaking fire protection system includes a power management module, a smoke sensor, an audible and visual alarm module, and a control execution module. The smoke sensor is electrically connected to both the power management module and the control execution module. The power management module supplies power to the smoke sensor, the audible and visual alarm module, and the control execution module. The smoke sensor is a scattering type photoelectric smoke sensor, which includes an infrared emitting tube, an infrared receiving tube, a detection cavity, and a signal processing circuit; the smoke sensor includes a first smoke sensor and a second smoke sensor. When neither the first smoke sensor nor the second smoke sensor detects smoke particles, the control execution module outputs a low-level signal, and the system is in standby mode. When the smoke particles detected by the first smoke sensor or the second smoke sensor exceed the first threshold, the first smoke sensor or the second smoke sensor outputs a high-level signal to the audible and visual alarm module, and the system triggers the audible and visual alarm signal. When the smoke particles detected by the first smoke sensor and the second smoke sensor both exceed the first threshold, the first smoke sensor and the second smoke sensor output a high-level signal to the control execution module, causing the window breaking system to break the window instantly.
[0006] Preferably, it also includes an oxygen sensor as an auxiliary trigger sensor, wherein the oxygen sensor is an electrochemical oxygen sensor and includes a gas-permeable membrane, a working electrode, a counter electrode, an electrolyte, and a signal acquisition circuit.
[0007] Preferably, when the oxygen sensor detects that the oxygen concentration is lower than the second threshold, the oxygen sensor outputs a high-level signal to the control execution module, causing the window breaking system to break the window instantly.
[0008] Preferably, it further includes a backup power management module, which is electrically connected to the smoke sensor, the audible and visual alarm module, and the control execution module. When the power management module fails, the backup power management module is used to supply power to the smoke sensor, the audible and visual alarm module, and the control execution module.
[0009] Preferably, the audible and visual alarm module is electrically connected to the audible and visual alarm module via a GPIO interface.
[0010] Preferably, when the fire hazard is eliminated or the system is reset, the audible and visual alarm module stops working and the system returns to standby mode.
[0011] Preferably, the window-breaking system breaks the window instantly by using an electromagnetic coil to attract the striking pin and shatter the glass.
[0012] Preferably, the system further includes a display module for electrical connection with the power management module, the display module being used to display the operating status and power parameters of the system.
[0013] Compared with the prior art, the technical solution of this utility model has beneficial effects.
[0014] This utility model provides an automatic window-breaking system for fire protection, comprising a power management module, a smoke sensor, an audible and visual alarm module, and a control execution module. The smoke sensor is electrically connected to both the power management module and the control execution module. The power management module supplies power to the smoke sensor, the audible and visual alarm module, and the control execution module. The smoke sensor is a scattering-type photoelectric smoke sensor, comprising an infrared emitting tube, an infrared receiving tube, a detection cavity, and a signal processing circuit. The smoke sensor includes a first smoke sensor and a second smoke sensor. When neither the first nor the second smoke sensor detects smoke particles, the control execution module outputs a low-level signal, and the system is in standby mode. When the smoke particles detected by either the first or second smoke sensor exceed a first threshold, the first or second smoke sensor outputs a high-level signal to the audible and visual alarm module, triggering the audible and visual alarm. When both the first and second smoke sensors detect smoke particles exceeding the first threshold, the first and second smoke sensors output a high-level signal to the control execution module, causing the window-breaking system to break the window instantly. By using multiple smoke sensors for environmental detection, the detection accuracy of the window-breaking system can be improved. Furthermore, it also includes an oxygen sensor as an auxiliary trigger sensor. The oxygen sensor is an electrochemical oxygen sensor, which includes a breathable membrane, a working electrode, a counter electrode, an electrolyte, and a signal acquisition circuit. When the oxygen sensor detects that the oxygen concentration is lower than a second threshold, the oxygen sensor outputs a high-level signal to the control execution module, causing the window breaking system to break the window instantly. By setting an oxygen sensor as an auxiliary trigger sensor, the limitations of the smoke sensor can be compensated for. For example, in some fire environments, although there is less smoke, oxygen is consumed quickly. Furthermore, it also includes a backup power management module, which is electrically connected to the smoke sensor, the audible and visual alarm module, and the control execution module. When the power management module fails, the backup power management module is used to supply power to the smoke sensor, the audible and visual alarm module, and the control execution module. By setting up a backup power management module, the failure of the power management module can be prevented from causing the entire window breaking system to stop working. Attached Figure Description

Detailed Implementation
[0016] To make the objectives, features, and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described below are merely for explaining this utility model and are not intended to limit it. Furthermore, the same or similar reference numerals may be used in the drawings to refer to the same or similar elements in different embodiments, and descriptions of the same or similar elements in different embodiments, as well as descriptions of prior art elements, features, effects, etc., may be omitted.

[0018] Reference Figures 1-3 This utility model provides an automatic window-breaking system for fire protection.
[0019] Specifically, the automatic window-breaking fire protection system includes a power management module 10, smoke sensors 111 and 112, an audible and visual alarm module 12, and a control execution module 13. The smoke sensors 111 and 112 are electrically connected to the power management module 10 and the control execution module 13, respectively. The power management module 10 is used to supply power to the smoke sensors 111 and 112, the audible and visual alarm module 12, and the control execution module 13. The smoke sensors 111 and 112 are scattering type photoelectric smoke sensors, each including an infrared emitting tube, an infrared receiving tube, a detection cavity, and a signal processing circuit; each includes a first smoke sensor 111 and a second smoke sensor 112. When neither the first smoke sensor 111 nor the second smoke sensor 112 detects smoke particles, the control execution module 13 outputs a low-level signal, and the system is in standby mode. When the smoke particles detected by the first smoke sensor 111 or the second smoke sensor 112 exceed the first threshold, the first smoke sensor 111 or the second smoke sensor 112 outputs a high-level signal to the audible and visual alarm module 12, and the system triggers the audible and visual alarm signal. When the smoke particles detected by the first smoke sensor 111 and the second smoke sensor 112 both exceed the first threshold, the first smoke sensor 111 and the second smoke sensor 112 output a high-level signal to the control execution module 13, causing the window breaking system to break the window instantly.
[0020] Specifically, the first threshold can be set according to the actual situation. Environmental detection is performed by the first smoke sensor 111 and the second smoke sensor 112, which can improve the detection accuracy of the window breaking system and avoid the error caused by the detection of a single smoke sensor.
[0021] In a specific implementation, an oxygen sensor 14 is also included as an auxiliary trigger sensor. The oxygen sensor 14 is an electrochemical oxygen sensor, comprising a breathable membrane, a working electrode, a counter electrode, an electrolyte, and a signal acquisition circuit. In a specific implementation, when the oxygen sensor 14 detects that the oxygen concentration is below a second threshold, the oxygen sensor 14 outputs a high-level signal to the control execution module 13, causing the window-breaking system to break the window instantly.
[0022] Specifically, the second threshold can be set according to the actual situation. At the fire scene, even if the first smoke sensor 111 and the second smoke sensor 112 do not detect any environmental abnormalities, that is, the smoke particles have not exceeded the first threshold, the oxygen concentration is lower than the second threshold. In order to prevent people from suffocating due to lack of oxygen, the breaking system needs to be driven to break the window instantly.
[0023] In a specific implementation, a backup power management module 100 is also included. The backup power management module 100 is electrically connected to the smoke sensors 111 and 112, the audible and visual alarm module 12, and the control execution module 13. When the power management module 10 fails, the backup power management module 100 is used to supply power to the smoke sensors 111 and 112, the audible and visual alarm module 12, and the control execution module 13.
[0024] Specifically, when the power management module 10 fails, the backup power module 100 is activated to supply power to each module, thereby ensuring that the window breaking system can work normally.
[0025] In a specific implementation, the audible and visual alarm module 12 is electrically connected to the audible and visual alarm module through a GPIO (General-Purpose Input / Output) interface.
[0026] In practice, once the fire hazard is eliminated or the system is reset, the audible and visual alarm module 12 stops working and the system returns to standby mode.
[0027] In practice, the instantaneous breaking of the window by the window-breaking system is achieved by using an electromagnetic coil to attract the striking pin and shatter the glass.
[0028] In a specific implementation, a display module is also included, which is electrically connected to the power management module 10. The display module is used to display the operating status and power parameters of the system.
[0029] In summary, this utility model provides an automatic window-breaking system for fire protection, comprising a power management module, a smoke sensor, an audible and visual alarm module, and a control execution module. The smoke sensor is electrically connected to both the power management module and the control execution module. The power management module supplies power to the smoke sensor, the audible and visual alarm module, and the control execution module. The smoke sensor is a scattering-type photoelectric smoke sensor, comprising an infrared emitting tube, an infrared receiving tube, a detection cavity, and a signal processing circuit. The smoke sensor includes a first smoke sensor and a second smoke sensor. When neither the first nor the second smoke sensor detects smoke particles, the control execution module outputs a low-level signal, and the system is in standby mode. When the smoke particles detected by either the first or second smoke sensor exceed a first threshold, the first or second smoke sensor outputs a high-level signal to the audible and visual alarm module, triggering the audible and visual alarm signal. When both the first and second smoke sensors detect smoke particles exceeding the first threshold, the first and second smoke sensors output a high-level signal to the control execution module, enabling the window-breaking system to break windows instantly. By using multiple smoke sensors for environmental detection, the detection accuracy of the window-breaking system can be improved. Furthermore, it also includes an oxygen sensor as an auxiliary trigger sensor. The oxygen sensor is an electrochemical oxygen sensor, which includes a breathable membrane, a working electrode, a counter electrode, an electrolyte, and a signal acquisition circuit. When the oxygen sensor detects that the oxygen concentration is lower than a second threshold, the oxygen sensor outputs a high-level signal to the control execution module, causing the window breaking system to break the window instantly.

When the power management module fails, the backup power management module is used to supply power to the smoke sensor, the audible and visual alarm module, and the control execution module. By setting up a backup power management module, the failure of the power management module can be prevented from causing the entire window breaking system to stop working.
