Description

Technical Field

[0001] The utility model relates to the technical field of detectors, in particular to a smoke detector and an alarm system. Background Art

[0002] At present, indoor detectors are usually powered by batteries. However, since the detectors need to be in a detection state all the time, the battery power will be continuously consumed. Once the battery runs out of power, the indoor detectors will lose their detection function. This requires the batteries to be frequently replaced in the places where the indoor detectors are installed. Once the battery replacement is forgotten, it is easy for the indoor detectors to fail to play their due detection role due to battery exhaustion, which undoubtedly makes the use of indoor detectors very inconvenient.

[0028] The present utility model provides an indoor detector.

[0029] Referring to Figure 1 , the indoor detector includes: a housing, a photoelectric conversion module 100, an energy storage module 200, and an electric control module 300. The photoelectric conversion module 100 is disposed on the outer side of the housing, and the energy storage module 200 and the electric control module 300 are disposed in the housing;

[0030] The energy storage module 200 is electrically connected to the photoelectric conversion module 100 and the electric control module 300 respectively. The energy storage module 200 is used to supply power for the operation of the electric control module 300. The photoelectric conversion module 100 is used to convert the received light energy into electrical energy and then output it to the energy storage module 200 to charge the energy storage module 200.

[0031] In this embodiment, the photoelectric conversion module 100 can be implemented using a polysilicon photoelectric or perovskite conversion module. The photoelectric conversion module 100 can be exposed outside the housing to receive the light in the environment where the indoor detector is installed, and can convert the received light into electrical energy and output a corresponding voltage. The electronic control module 300 includes various functional modules that need to be powered to maintain the working state in the indoor detector, such as the detection module 300, etc. The energy storage module 200 can use a battery or a super capacitor to discharge and provide power for the operation of the electronic control module 300.

[0032] In the technical solution of the present utility model, by arranging the photoelectric conversion module 100 on the outer side of the housing, since the installation environment of the indoor detector is usually in a family room, an office, a shopping mall, etc., and there are often lighting lights with a long existence time, a high light intensity, and stability in such installation environments, it is possible to charge the energy storage module 200 by using the lighting lights in the installation environment, thereby improving the endurance of the energy storage module 200, and further achieving the purpose of reducing the number of battery replacements in the indoor detector. And since renewable energy (light energy) is used as the main power source, the dependence on traditional batteries is reduced, and environmental pollution is reduced.

[0033] Referring to Figure 2 and Figure 3 , the electronic control module 300 includes a detection module 300, a main controller 320, and an alarm module 330;

[0034] The main controller 320 is respectively connected to the detection module 300 and the alarm module 330. The main controller 320 accesses the detection signal output by the detection module 300 and is used to control the alarm module 330 to send an alarm message when the detection signal reaches a preset standard.

[0035] In this embodiment, the main controller 320 can be implemented by a microprocessor such as an MCU, a DSP, or an FPGA, or can also be implemented by a CPU main control chip; the detection module 300 can be an indoor detection module such as a smoke detection module, a gas detection module, a carbon monoxide detection module, or a temperature detection module; the alarm module 330 can be implemented by a functional module such as a buzzer or a speaker that can emit sound and light information. The detection module 300 can detect the environmental parameters in the room in real time (such as smoke concentration, gas concentration, carbon monoxide concentration, ambient temperature), and output corresponding detection signals to the main controller 320. The main controller 320 can convert the received detection signals through analog-to-digital conversion and continuously compare them with preset parameters representing preset standards, and can determine whether the preset standards are met according to the comparison results. For example, it can be determined that the preset standards are met when the detection signal is not less than the preset parameters. The main controller 320 can also control the alarm module 330 to emit sound and light alarm information when it is determined that the detection signal reaches the preset standard, so as to give corresponding prompts to the people in the environment. In this way, the alarm function of the indoor detector can be realized.

[0036] In another alternative embodiment, the alarm module 330 is implemented by a buzzer sheet 331.

[0037] Optionally, the detection module 300 is any one or a combination of a smoke detection module, a gas detection module, a carbon monoxide detection module, and a temperature detection module. Among them, the smoke detection module is used to detect the smoke concentration in the environment; the gas detection module is used to detect the gas concentration in the environment; the carbon monoxide detection module is used to detect the carbon monoxide detection module concentration in the environment; the temperature detection module is used to detect the temperature of the environment where the indoor detector is located.

[0038] Optionally, the smoke detection module includes a darkroom housing and an infrared pair tube assembly, and the infrared pair tube assembly is arranged in the darkroom housing.

[0039] In this embodiment, the infrared pair tube assembly includes an infrared emitting tube 313 and an infrared receiving tube 314. The darkroom housing includes an optical darkroom bottom shell 311 and an optical darkroom upper cover 312, and the two can be enclosed to form the darkroom housing; air holes are provided on the darkroom housing for air in the environment to diffuse between the infrared emitting tube 313 and the infrared receiving tube 314 through the air holes. When the smoke content in the environment rises, the air containing smoke will affect the infrared light emitted by the infrared emitting tube 313, thereby affecting the voltage output by the infrared receiving tube 314 after receiving the infrared light, so as to realize the detection of smoke in the environment. And the technical solution of the present utility model can reduce the influence of infrared light in the ambient light on the infrared pair tube assembly as much as possible by arranging the infrared pair tube assembly in the darkroom housing, which is beneficial to improving the smoke alarm accuracy.

[0040] Optionally, a shielding cover 315 is further provided in the darkroom housing.

[0041] In this embodiment, the shielding cover 315 is configured to shield the infrared pair tube assembly to reduce the influence of electromagnetic signals in the environment on the working state of the infrared pair tube assembly, thereby further reducing the influence of infrared light in ambient light on the infrared pair tube assembly.

[0042] Optionally, a light-shielding sheet 316 is further provided in the darkroom housing. The light-shielding sheet 316 can be arranged near the air hole in the darkroom housing. The light-shielding sheet 316 is used to reduce the ambient light entering from the air hole while ensuring that the air hole can intake air, thereby further reducing the influence of infrared light in ambient light on the infrared pair tube assembly.

[0043] Optionally, the indoor detector further includes:

[0044] A power management module (not shown in the figure), the power management module is respectively connected to the main controller 320, the energy storage module 200 and the photoelectric conversion module 100. The power management module is used to adjust the charging voltage output by the photoelectric conversion module 100 to the energy storage module 200 under the control of the main controller 320, and is further used to control the power supply voltages respectively output by the energy storage module 200 to the detection module 300 and the alarm module 330.

[0045] In this embodiment, the power management module can be implemented by a power management integrated chip and its peripheral circuits. The power management module can perform corresponding voltage conversion on the output voltage of the energy storage module 200 under the control of the main controller 320, so as to convert the output voltage of the energy storage module 200 into a suitable power supply voltage and then output it to the detection module 300 and the alarm module 330 to ensure the power supply stability for the detection module 300 and the alarm module 330. And the power management module can also monitor the electric energy output by the photoelectric conversion module 100 under the control of the main controller 320. Specifically, the output voltage connected from the photoelectric conversion module 100 is compared with a preset voltage threshold. Only when its output voltage is greater than the preset voltage threshold (that is, it means that the light in the current environment is relatively strong), the power management module will perform corresponding voltage change on the output voltage of the photoelectric conversion module 100 and output the changed output voltage to the energy storage module 200 for charging it. Among them, the voltage conversion can be a boost conversion or a buck conversion, and this embodiment does not limit this. In this way, by setting the power management module, it can be avoided that the photoelectric conversion module 100 directly outputs too high or too low electric energy to the energy storage module 200 due to too strong or too weak light, thereby realizing overvoltage charging protection and undervoltage charging protection for the energy storage module 200.

[0046] Optionally, the housing includes a front shell 400, a rear shell 500 and a hanging bracket 600;

[0047] The photoelectric conversion module 100 is disposed on the outer side of the front case 400. The front case 400 and the rear case 500 enclose to form a receiving space. The energy storage module 200 and the electronic control module 300 are accommodated in the receiving space. The rear case 500 is installed in the hanging bracket 600.

[0048] Optionally, the energy storage module 200 is a lithium iron phosphate battery. Since the lithium iron phosphate battery has the characteristics of high energy density and long life, it can meet the power supply requirements for the long-term stable operation of the indoor detector. At the same time, the lithium iron phosphate battery also has high environmental protection performance, which can further reflect the energy-saving and environmental protection advantages of the detector.

[0049] Optionally, the housing includes a front case 400, a rear case 500 and a hanging bracket 600;

[0050] The photoelectric conversion module 100 is disposed on the outer side of the front case 400. The front case 400 and the rear case 500 enclose to form a receiving space. The energy storage module 200 and the electronic control module 300 are accommodated in the receiving space. The rear case 500 is installed in the hanging bracket 600.

[0051] The front case 400 and the rear case 500 enclose to form a nearly cylindrical housing. A main board 700 is also accommodated in the receiving space. The main controller 320 can be disposed on the main board 700. The energy storage module 200 can be arranged on one side of the main board 700. The alarm module 330 can be disposed between the main board 700 and the front case 400. The detection module 300 can be disposed between the main board 700 and the rear case 500. The rear case 500 can be installed on the hanging bracket 600, and the hanging bracket 600 is used for installing the indoor detector indoors. At the same time, the photoelectric conversion module 100 is disposed on the front case 400 and is exposed on the front case 400, so that it is convenient to convert into electric energy to receive light energy after the indoor detector is installed.
