Description of the Invention: [Technical Field] The present invention relates to a long-distance infrared adjustable smoke sensor, and more particularly to a smoke sensing system using a separate infrared type as a transceiver module The tenth of the lens and the optical path, the price measurement (4) is raised to a long-distance infrared adjustable smoke sensor of about 1 metric meter. [Prior Art] Generally, there are three major conditions for combustion, fuel, proper high temperature, and oxygen. However, most of the combustion lacks enough oxygen to cause incomplete combustion, and many carbon particles are generated to form smoke. The smoke alarm is to use the above phenomenon to continuously detect the air, and once the smoke is detected, an alarm is issued to achieve the effect of the warning. According to the fire statistics, the number of deaths due to fire in the country exceeds 80/.疋 Because it inhales too much smoke and suffocates, so the smoke alarm will be an indispensable safety device. The fire detectors are divided into three categories, which are discussed in detail below: 1 • Temperature type fire detector: This temperature type fire detector senses the temperature generated by the fire. When the upper limit temperature is reached, it is activated. The controller sends out an alarm' and the sensor uses temperature as its sensing medium. When the sensing environment is low temperature or air-conditioned, the sensitivity and performance of the early detection of fire will be greatly reduced. 2. Ion-type fire smoke detector: λ-ion fire smoke detector, which uses the radiation chemical element tungsten 1262300. After the shortcomings, the detector, Nai Sisi improved and created #', and after years of painstaking research, finally successfully developed this piece. BACKGROUND OF THE INVENTION The object of the present invention is to provide a long-distance infrared adjustable smoke sensor that emits a red line beam and receives the infrared beam. The receiver is used as a fire monitoring, and after the infrared beam emitted by the transmitter passes through the first operational amplifier and the first optical lens, the signal of the infrared beam can be enhanced and concentrated, so that the infrared beam can reach about 100 meters. The range, if the infrared beam is interrupted by smoke caused by a fire, will automatically activate the smoke sensor of the present invention. Therefore, it is extremely practical for a large space area and a factory with a high building structure. Sex. A second object of the present invention is to provide a long-distance infrared adjustable smoke sensor 1 that emits an infrared light beam to monitor the presence of smoke. Therefore, this method can be used to measure smoke in a wide range, and it will not Harm to human health. Another object of the present invention is to provide a long-distance infrared adjustable smoke sensing device. The dip switch provided in the control circuit of the receiver can adjust the sense of sensation for the environment to be used, and the sensitivity system can be divided into 25%, 35%, and 50% options. A long-range infrared adjustable smoke sensor 1262300 that achieves the above-mentioned objectives. It includes a transmitter's - operational amplifier that can be used for ικ Hz shock. , the light-emitting diode system emits an infrared light beam, and - the infrared light beam can be concentrated and the length of the infrared light beam is extended - the first optical lens receiver is a light-emitting diode that receives the infrared light beam The main body is coupled to a second optical lens, and the second port is sent to a back-end control circuit system by a second operational amplifier and a filter. The receiver receives the infrared light emitted by the transmitter. The light beam is used to monitor the attenuation degree of the signal to achieve the function of smoke detection. [Embodiment] One of the present invention is provided by referring to FIG. 1 to FIG. The long-distance infrared adjustable smoke sensor mainly comprises a transmitter 丨 and a receiver 2, and the transmitter 1 can project a specific signal to the receiver 2, and then analyze and compare the signals, and when detected, The smoke sensor of the present invention will activate the warning after the smoke generated by the fire blocks the covered path of the system and reaches the set concentration and time. The smoke sensor of the present invention will automatically disarm after the smoke is removed. The transmitter 1 has a first operational amplifier 11 that amplifies a signal for 1 κ Hz, a light-emitting diode 12 emits an infrared light beam 121, and a light beam 121 can be concentrated. And the divergence angle of the LED 12 can be effectively reduced, and the optical lens 13' of the extended distance of the infrared long beam 121 is shown in FIG. 1. In the embodiment, the circuit of the first 1262300 is The design part of the optical lens 13 is a convex lens, and the emitter is as shown in FIG. 2. The receiving state 2' is a diode that receives the infrared beam as a main body 2 and is coupled with a second optical lens 22. As shown in FIG. 3, in the present embodiment, the second optical lens 22 is also a convex lens, and then the second operational amplifier 23 and a filter 24 are sent to a back-end control circuit. The control circuit system 25 has a control comparison circuit 25:1', as shown in FIG. 4, the degree of attenuation of the signal is measured and compared, and the control comparison circuit 251 is further provided with an optical coupler 252. Signal isolation, as shown in Figure 5, to keep the signal of the receiver 2 stable, and both the transmitter and the receiver g must form an optical system with a convex lens to reduce the divergence angle to achieve a long-range range of motion. The other feature of the system is to use the optical coupler for signal isolation, so that the system can be installed in the harsh environment of the factory for environmental interference to the minimum, and still maintain a certain degree of stability and reliability. The 4 control comparison circuit 2 51 includes a microprocessor 2 5 3, and a dip switch 254 that can set the tobacco/agricultural degree to 25%, 35%, and 50%, and an alarm indicator 255; After receiving the signal of the backend control circuit system 25, the microprocessor 253 uses the delay of the second number to determine whether it is a fire signal. If not, it is ignored, and the alarm is automatically started or released in time, as shown in FIG. To control the comparison circuit diagram. 1262300, as shown in FIG. 6, the transmitter 1 and the receiver 2 are separate entities, and are horizontally in a state of each other. Therefore, under normal circumstances, the receiver 2 detects the transmitter 1 The emitted infrared light beam 21, however, such as when a fire occurs, the smoke generated by the fire will cause scattering and shielding of the infrared light beam 121, thereby causing the control comparison circuit 251 to detect the attenuation of the infrared light beam 121. A warning is issued and the backend control circuitry 25 automatically deactivates the alarm after the smoke is removed. Furthermore, the finger switch 254 of the rear control circuit system 25 of the receiver 2 can provide three different concentrations of concentrated smoke carbon particles, which are 25%, 35% and 50% respectively (25% is a commonly used sensitivity value). A long-range infrared adjustable smoke sensor for use in the present invention is suitable for use in various situations in different environments. In addition, the back-end control circuit system 25 is provided with an optical coupler 252 to isolate the signals, so that the invention can minimize the interference to the environment, so 'when installed in a factory or in a harsh environment, it can still be maintained. Certain stability and reliability. In addition, the infrared light beam 121 emitted by the light-emitting diode 12 of the emitter 1 is astigmatism, and the signal needs to be amplified by the first operational amplifier ,, and then the first optical lens 13 The infrared ray beam 126 is condensed and emitted, and the emitted infrared ray beam 121 is condensed again through the second optical lens 22 of the receiver 2, and then the signal weakened by the second operational amplifier 23 is further amplified by 1262300 times. The invented smoke sensor can monitor a distance of about 100 meters long, and therefore has great practicality for a large space area and a factory with a high building structure. [Features and Efficacy] The long-distance infrared adjustable smoke sensor provided by the present invention has the following advantages when compared with each other: (1) one of the features of the present invention.
