Description

Technical Field

[0001] This utility model relates to the field of smoke detectors, and in particular to a long-distance beam smoke detector system. Background Technology

[0002] Currently available linear smoke detectors are typically designed for short-range detection, generally not exceeding 100 meters. Because existing detection technology cannot meet the demands of ultra-long-range detection, these short-to-medium range fire detectors are unsuitable for large buildings (such as warehouses, industrial plants, large shopping malls, and tunnels). This can lead to the failure to detect early-stage smoke in a timely manner, increasing fire safety hazards. Therefore, there is an urgent need for a linear smoke detector with a detection range of up to 160 meters to solve this problem. Utility Model Content

[0003] To address the aforementioned issues, this technical solution provides a long-range beam smoke detector system.

[0004] To achieve the above objectives, the technical solution is as follows:

[0006] The main control unit is used to send control signals;

[0007] The transmitting unit, connected to the main control unit, is used to transmit light to the reflecting unit;

[0008] A receiving unit, connected to the main control unit, is used to receive light from the reflecting unit;

[0009] The detection unit is connected to the main control unit and the receiving unit, and is used to detect whether the light intensity is too high after receiving the optical signal from the receiving unit.

[0010] An amplification unit, connected to the main control unit and the detection unit, is used to select and amplify the optical signal.

[0011] The filtering unit, connected to the main control unit and the amplification unit, is used to filter stray light signals and feed the light signals back to the main control unit to identify whether smoke has occurred in the current environment.

[0012] In some embodiments, the emitting unit is an infrared LED light.

[0013] In some embodiments, the receiving unit is a photodiode.

[0014] The beneficial effects of this application are:

[0015] This application uses light emission, reflection, and reception by a receiving unit to determine the smoke concentration in the detection area and triggers an alarm based on the concentration level, ensuring a detection range of 160 meters. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the system structure of an embodiment of the present utility model;

[0019] Figure 3 This is a flowchart illustrating an embodiment of the present utility model. Detailed Implementation

[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please refer to Figure 1-3 As shown, a long-range beam smoke detector system includes:

[0022] The main control unit is used to send control signals;

[0023] The transmitting unit, connected to the main control unit, is used to transmit light to the reflecting unit;

[0024] A receiving unit, connected to the main control unit, is used to receive light from the reflecting unit;

[0025] The detection unit is connected to the main control unit and the receiving unit, and is used to detect whether the light intensity is too high after receiving the optical signal from the receiving unit.

[0026] An amplification unit, connected to the main control unit and the detection unit, is used to select and amplify the optical signal.

[0027] The filtering unit, connected to the main control unit and the amplification unit, is used to filter stray light signals and feed the light signals back to the main control unit to identify whether smoke has occurred in the current environment.

[0028] Specifically, the transmitting unit is an infrared LED light.

[0029] Specifically, the receiving unit is a photodiode.

[0030] like Figure 2 As shown, the detector is located on one side and the reflector is located on the other side. After the infrared light is emitted, if the smoke concentration is too high, the reflector cannot reflect the light. If the concentration is too low, the receiver will receive various types of light, including natural light, ambient light, and infrared signal light. The detection unit determines the current smoke concentration based on the amount of light received. Then, the light signal reaches the amplification unit. Since each type of light has a different frequency, the amplification unit filters and amplifies the light signal of the corresponding frequency. Finally, unsuitable light signals are filtered by the filtering unit, and the remaining light signal is the detected infrared light signal, which is fed back to the main control unit, thus determining the smoke concentration in the current detection area. The optimized optical design and intelligent signal processing enable the system to work stably in various environments.

[0031] High-power infrared LEDs are selected as the emission light source to enhance sensitivity to smoke particles. A high-sensitivity photodiode is used as the receiver, enabling precise measurement of light intensity changes after scattering by smoke particles, ensuring stable light transmission within a 160-meter range. Furthermore, it accurately filters and amplifies the received light signal, precisely determining the smoke concentration and automatically setting alarm thresholds based on changes in the intensity of the received light signal, while also possessing the ability to suppress optical noise interference. These modules combined achieve accurate smoke detection within a 160-meter range.

[0032] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
