Description

Technical Field

[0001] This invention relates to the field of control system technology, and more specifically to a control system and a light-emitting bracket for indicating the location of a fire extinguisher in conjunction with a security alarm. Background Technology

[0002] Smoke detectors are essential security alarms in residences and office buildings. When a fire occurs in the environment, the smoke detector will sound an alarm to remind users of the fire hazard and notify them to evacuate, minimizing casualties. In general, when a fire occurs, users should first evacuate the fire site quickly, or they can use the fire extinguishers placed in the building to extinguish the fire and eliminate the danger. However, when a fire occurs, the large amount of smoke reduces the user's visibility, making it difficult for the user to identify the location of the fire extinguisher and find it.

[0003] Therefore, the applicant proposes a control system and a light-emitting bracket that are linked to a security alarm to indicate the location of a fire extinguisher. The light-emitting bracket emits light when a fire occurs to remind the user of the location of the fire extinguisher, allowing the user to quickly find the fire extinguisher and continue to extinguish the fire quickly.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] In the description of this application, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Example 1 Please refer to a control system for indicating the location of fire extinguishers that is linked to a security alarm. Figure 1 , Figures 2a-2f As shown, it includes: a micro central processing unit 100, a wireless receiver module 200, a wired connection module 300, a light sensor 400, a low-light module 500, a high-light module 600, a temperature sensor module 700, and a power supply module 800.

[0022] The control system is applied to the luminous bracket for storing fire extinguishers. The micro central processing unit 100 processes the received signals and issues control commands. The wireless receiver module 200 is connected to the micro central processing unit 100, and the wireless receiver module 200 communicates with the security alarm wirelessly. The wireless receiver module 200 receives alarm signals from the security alarm and transmits the signals to the micro central processing unit 100.

[0023] In this embodiment, the security alarm refers to a smoke alarm.

[0024] The wireless receiving module 200 is any one of an RF module, a WIFI module, a ZIGBEE module, an NB-IoT module, and a 4G module; the security alarm is equipped with a wireless transmitting module that matches the wireless receiving module 200. If the wireless receiver module 200 is an RF module, specifically an RF receiver module; then the security alarm is equipped with an RF transmitter module, which, through the RF receiver module and the RF transmitter module, enables the security alarm to send alarm signals to the control system. For example, the 200ZIGBEE wireless receiver module is specifically a ZIGBEE receiver module; then the security alarm is equipped with a ZIGBEE transmitter module, and the security alarm sends alarm signals to the control system through the ZIGBEE receiver module and the ZIGBEE transmitter module.

[0025] The wired connection module 300 is connected to the micro central processing unit 100, and the wired connection module 300 communicates with the security alarm via a wired connection. The wired connection module 300 can be any one of the following: IO interface, RS485 interface, TTL interface, and RS232 interface. Therefore, the security alarm should be equipped with a matching interface. For example, if the wired connection module 300 has an I / O interface, then the security alarm device also has an I / O interface and is connected via a wire; For example, if the wired connection module 300 is equipped with an RS485 interface, then the security alarm device is also equipped with an RS485 interface and is connected via a wire.

[0026] As mentioned above, the control system can reserve a wired connection module 300 and a wireless receiving module 200. When the light-emitting bracket with this control module is used in a building, the user can choose to connect the control system and the security alarm wirelessly or wiredly, depending on the actual needs.

[0027] Alternatively, the control system may only have one of the wired connection module 300 and the wireless receiving module 200, which can reduce costs.

[0028] The light sensor 400 is used to sense ambient light. The light sensor 400 is connected to the micro central processing unit 100. The light sensor 400 can be any one of a photoresistor, a photodiode, or a phototransistor. In this embodiment, a photoresistor is used.

[0029] The light sensor 400 senses ambient light and sends a light signal to the micro central processing unit 100; Here, the light signal actually refers to the electrical signal. The working principle of the photoresistor is based on the internal photoelectric effect. When light shines on the semiconductor photosensitive material, the photons interact with the atoms or molecules in the semiconductor material, converting some of the light energy into the kinetic energy of electrons, causing the electrons to jump from the valence band to the conduction band, forming free electron-hole pairs, thereby increasing the conductivity of the semiconductor material and reducing its resistance value.

[0030] The higher the light intensity, the more electron-hole pairs are generated, and the lower the resistance of the photoresistor. Conversely, when the light intensity decreases or disappears, these electron-hole pairs recombine, and the resistance gradually returns to the initial dark resistance state. As light intensity increases, resistance decreases; as light intensity decreases, resistance increases, which in turn causes a change in current. The micro central processing unit 100 then issues corresponding instructions based on the changes in the electrical signal.

[0031] The low-light module 500 emits a dim light to indicate the location of the fire extinguisher when the ambient light is dim. The high-intensity light module 600 emits a strong light to indicate the location of fire extinguishers during a fire. The low-light module 500 and the high-light module 600 are LEDs or lighting tubes. Preferably, the low-light module 500 and the high-light module 600 are LEDs.

[0032] The micro central processing unit 100 receives alarm signals from the security alarm via the wireless receiving module 200 or the wired connection module 300 and controls the operation of the high-intensity light module 600; the micro central processing unit 100 receives light signals from the light sensor 400 and controls the operation of the low-intensity light module 500.

[0033] Specifically, when there is no fire hazard, the micro central processing unit 100 controls the operation of the low-light module 500 based on the light signal from the light sensor 400. For example, during the day, when the light intensity is sufficient, the user can clearly observe the location of the fire extinguisher without the need for auxiliary light, and the low-light module 500 is turned off. At night, when the light intensity is insufficient, the user has difficulty observing the location of the fire extinguisher. At this time, the micro central processing unit 100 controls the operation of the low-light module 500 based on the light signal from the light sensor 400, and the low-light module 500 emits light to indicate the location of the fire extinguisher.

[0034] For example, even during the day, if the building is dimly lit and the light intensity is insufficient, it is difficult for users to observe the location of the fire extinguisher. In this case, the micro central processing unit 100 controls the low light module 500 to operate according to the light signal from the light sensor 400. The low light module 500 emits light, which can indicate the location of the fire extinguisher.

[0035] In the event of a fire hazard, the micro central processing unit 100 controls the high-intensity light module 600 to operate based on the alarm signal received by the wired connection module 300 or the wireless receiving module 200, emitting a bright light so that users can observe the location of the fire extinguisher even in a smoke-filled environment.

[0036] For example, a temperature sensor module 700 may also be provided, which is used to detect the ambient temperature; In the event of a smoke alarm failure, when the ambient temperature reaches a certain level, the micro central processing unit 100 controls the high-intensity light module 600 to operate. Generally speaking, in China, the highest temperature in summer is usually no more than 40°C, and the highest temperature in some areas is usually no more than 50°C. In the event of a fire, the ambient temperature will rise significantly. If the temperature sensor module 700 detects that the ambient temperature has reached 70°C, the micro central processing unit 100 controls the high-intensity light module 600 to operate.

[0037] Optionally, depending on actual use, the above temperature value of 70°C can be modified, such as set to 60°C, 65°C, 80°C, etc., and the micro central processing unit 100 controls the operation of the high-intensity lamp module 600.

[0038] Optionally, the light color of the high-intensity light module 600 can be red or yellow; Optionally, the high-intensity light module 600 may flash during operation.

[0039] The aforementioned high-intensity light module 600 can also continuously emit light in the event of a fire hazard. In addition to indicating the location of fire extinguishers, it can also serve as lighting, illuminating the environment and improving the user's visibility.

[0040] For example, it also includes a power module 800, which provides power to the control system. The power module 800 can be a power interface that is directly connected to the mains power through a power cord; or it can be equipped with a battery to power the control system.

[0041] Of course, AC power can also be used for power supply; Optionally, when the control system is powered by AC power or a power adapter, the power module 800 may also include a backup battery, which provides power to the control system during a power outage to ensure normal operation.

[0042] Figure 2 shows a schematic diagram of the specific circuit of this control system, which enables the control system to be linked with the security alarm.

[0043] Example 2: A luminous bracket has a bracket body with a location for accommodating a fire extinguisher. It includes: a control system, as described in Embodiment 1, linked to a security alarm for indicating the location of the fire extinguisher; the fire extinguisher can be accommodated on the bracket body. In the event of a fire, the smoke alarm sends an alarm signal to the control system of the luminous bracket, and a high-intensity light module 600 illuminates, allowing the user to clearly see the location of the fire extinguisher and quickly retrieve it.

[0044] Example 3: In the same building, there may be multiple light-emitting brackets placed in different locations. The control systems of the multiple light-emitting brackets are connected by communication, which can be wireless or wired. When the control system of one light-emitting bracket receives an alarm signal from a smoke detector, the high-intensity light module 600 of one light-emitting bracket lights up, and the high-intensity light modules 600 of the other light-emitting brackets light up at the same time. Alternatively, the control systems of the luminous brackets on different floors can be connected for communication. For example, when a fire occurs on the 5th floor, the smoke detector on the 5th floor sends an alarm signal to the control system of the luminous bracket on the 5th floor, and the high-intensity light module 600 of the luminous bracket on the 5th floor lights up. At the same time, the high-intensity light modules 600 of the luminous brackets on other floors light up.

[0045] This invention connects the control system of the luminous bracket to a smoke detector, ultimately enabling the high-intensity light module 600 to illuminate and inform the user of the specific location of the fire extinguisher when a fire occurs.
