[0002] With the continuous advancement of industrialization, smoke and dust emissions are a growing concern. Atmospheric smoke and dust not only impacts environmental quality but also poses potential risks to human health. Existing smoke and dust monitoring equipment is mostly fixed, wired, and subject to significant geographical restrictions. It also lacks real-time performance and flexibility. With the maturity of wireless transmission technology, smoke and dust monitoring equipment that combines wireless transmission and sensing technologies has emerged, providing environmental protection departments with more real-time, flexible, and efficient monitoring tools. Utility Model Content

[0003] The purpose of the utility model is to solve the above deficiencies in the prior art and to provide a smoke and dust monitor with real-time wireless transmission.

The monitoring device includes a laser light source, a beam adjuster, a photodetector, and an optical chamber. The beam adjuster quickly focuses or collimates the laser. The optical chamber is the intersection of the laser light source, the sampling channel, and the photodetector. Smoke particles in the air are irradiated by the laser beam in the optical chamber, generating scattered light. The photodetector is used to receive the light scattered by the smoke particles. The photodetector converts the optical signal into an electrical signal. The electrical signal is formed into a digital signal through an amplifier or an analog-to-digital converter. The digital signal is transmitted to the data processing module. The wireless transmission module receives analyzed smoke concentration data from the data processing module.

[0010] Beneficial effects:

[0011] The utility model is cleverly designed and solves the problem that traditional wired monitoring equipment is limited by wiring and location through a wireless transmission module, thereby realizing real-time remote monitoring.

[0012] 1. No wiring required, flexible installation

[0013] Wireless transmission technology eliminates the need for physical cables and communication lines, making equipment installation easier. Whether at a fixed monitoring site or in mobile or difficult-to-wire environments such as high-rise buildings, construction sites, and mountainous areas, wireless transmission can be flexibly deployed.

[0014] In harsh industrial environments or complex geographical locations, laying wired communication lines may be very difficult or even impossible. Wireless transmission can easily meet these challenges and adapt to more application scenarios.

[0015] 2. Real-time data transmission

[0016] Efficient real-time monitoring: Wireless transmission can transmit monitored smoke and dust data to a remote control center or cloud platform in near real-time, ensuring data timeliness. For situations requiring rapid response, such as sudden air pollution incidents or abnormal industrial emissions, wireless transmission can provide timely warnings.

[0017] Low-latency transmission: Through advanced wireless communication technologies such as 4G / 5G, Wi-Fi, LoRa, etc., wireless transmission can provide low-latency data transmission, ensuring that monitoring data can be delivered to the management system or control terminal in real time.

[0018] 3. Remote monitoring and management

[0019] Remote Access and Control: Wireless transmission supports remote monitoring systems, allowing managers to view real-time data, analysis results, and equipment operating status from anywhere via the internet or a dedicated network. This significantly reduces the frequency of on-site maintenance and management, improving system efficiency.

[0020] Remote configuration and maintenance: Not only can data be acquired remotely, but devices can also be debugged, configured, and software updated remotely, significantly reducing maintenance costs. When system anomalies occur, managers can remotely troubleshoot the problem, reducing the number of on-site interventions.

[0021] 4. Wide data transmission range and strong adaptability

[0022] Wide coverage: Modern wireless communication technologies such as LoRa and NB-IoT have ultra-long-distance transmission capabilities and are particularly suitable for wide-area monitoring systems. They can achieve large-scale smoke and dust monitoring in cities, industrial parks and even remote areas.

[0023] Strong penetration capability: Some wireless technologies, such as LoRa and NB-IoT, have strong signal penetration capabilities and can penetrate obstacles such as buildings and trees, making them suitable for complex urban or industrial environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 This is a schematic diagram of the overall structure of a smoke and dust monitor with real-time wireless transmission; DETAILED DESCRIPTION

[0025] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0026] like Figure 1 As shown, a real-time wireless transmission smoke monitor includes a smoke collection module, a data processing module and a wireless transmission module;

[0027] The smoke collection module includes a micro fan or pump device, which is used to introduce external air into the monitoring device through the sampling channel. The sampling channel is equipped with a filter device to prevent larger particles from entering the sensor. The monitoring device includes a laser light source, a beam adjuster, a photodetector, and an optical chamber. The laser light source usually uses a laser diode as a light source, emitting a stable laser beam to illuminate the smoke particles in the sampling channel. The wavelength of the laser light source is generally selected in the visible light or near-infrared range, with common wavelengths of 650nm or 850nm.

[0028] The beam adjuster quickly focuses or collimates the laser to ensure that its energy is concentrated in the sampling area, thereby improving measurement accuracy. The beam adjuster can be a lens, reflector or other optical element to ensure that the laser beam forms a stable illumination area in the sampling channel.

[0029] Photodetectors, such as photodiodes or photomultiplier tubes, are used to receive light scattered by smoke particles. The intensity of the scattered light is proportional to the concentration of the particles. Therefore, by detecting changes in the scattered light, the photodetector can indirectly calculate the concentration of particles in the air. To improve measurement accuracy, the smoke collection module may be equipped with multiple photodetectors located at different angles to detect scattered light signals in different directions. Common angles are 90-degree side scatter and forward scatter.

[0030] The optical chamber is the intersection of the laser light source, sampling channel, and photodetector. Airborne soot particles are irradiated by the laser beam in the optical chamber, generating scattered light. To improve detection efficiency, the interior of the optical chamber is usually coated with an anti-reflection coating to reduce interference caused by internal light reflections. Also, a reflector may be installed to guide the scattered light to the photodetector, further improving detection accuracy.

[0031] The photodetector converts the optical signal into an electrical signal, which is then converted into a digital signal through an amplifier or an analog-to-digital converter. The digital signal is then transmitted to the data processing module. The wireless transmission module receives the analyzed smoke concentration data from the data processing module. The wireless transmission module includes a communication chip and an antenna system. The communication chip is used to execute specific wireless transmission protocols. Wireless transmission protocols include Wi-Fi, cellular networks, LoRa, and NB-IoT. The antenna system is used to receive and send wireless signals. The wireless transmission module is equipped with an embedded protocol stack. The transmission protocols of the embedded protocol stack include TCP / IP, UDP, and MQTT, which are used to process the encapsulation, transmission, error correction, and confirmation of data packets. The wireless transmission module transmits smoke monitoring data from the device end to a remote server or user terminal in real time.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
