[0017] Reference Figure 1-4 As shown, an online monitoring device for dust accumulation and full-range dust concentration includes a dust collection bin 1, a weighing component 2, and a dust module 3. The lower end of the dust collection bin 1 is connected to the weighing component 2, and the lower end of the weighing component 2 is connected to the dust module 3.
[0018] Specifically, the dust collection bin 1 includes an upper dust collection bin 101, the lower end of which is threadedly connected to a lower dust collection bin 102.
[0019] Specifically, the weighing component 2 includes a balance 201, a lifting mechanism 202 is fixedly installed at the left end of the balance 201, a lifting tray 203 is movably connected to the top of the lifting mechanism 202, and a dust collection tray 204 is fixedly connected to the lifting tray 203.
[0020] Specifically, the dust module 3 includes a dilution chamber 301. The outer wall of the dilution chamber 301 is provided with a pipe 3011, a valve 3012, a pipe 3013, a valve 3014, a valve 3015, a pipe 3016, a valve 4, a pipe 4, a valve 5, a valve 6, a sampling pipe 3021, and a dust concentration sensor 4, forming an environment that is both closed and open. The specific state is controlled by the corresponding valves.
[0021] Furthermore, valve 3012 is placed at the top of dilution chamber 301 to control the entry of zero gas; valve 3017 is placed at the bottom of dilution chamber 301 to control the discharge of detected gas.
[0022] Furthermore, the dilution chamber 301 has a cavity structure, and a pressurization device is installed inside the dilution chamber 301.
[0023] Furthermore, a sampling gas inlet 5 is provided at the tee connection between the sampling tube 3021 and the tube 3011 for introducing detection gas.
[0024] Furthermore, a sampling gas outlet 6 is provided at the tee connection between the sampling tube 3021 and the tube 3015 for discharging the gas being tested.
[0025] Specifically, an online monitoring system for dust accumulation and full-range dust concentration comprises a dust collection bin 1, a weighing component 2, and a dust module 3, including: S1 Dust Accumulation Acquisition Module: Composed of dust accumulation bin 1, this system is used to collect data on the gas being monitored. S2 Dust Concentration Monitoring Module: Monitors the dust concentration of the gas being tested through a micro-weight sensor installed in the weighing component 2; S3 Communication Module: Connected to the AI algorithm via the router, responsible for establishing communication links and transmitting collected data and control signals; S4 Control and Data Storage Module: An electrical component used to connect the dust accumulation module, dust concentration monitoring module, and communication module.

[0026] Furthermore, the S4 control and data storage module is controlled and monitored by the main control board 7 located on the outer wall of the dilution chamber 301.
[0027] The working principle of this invention is as follows: When the device is working, when the dust concentration is low, that is, within the range of the dust concentration sensor 4, the gas being detected is discharged through the sampling gas inlet 5, valve 2 3014, sampling tube 3021, valve 3015, and then through the sampling gas outlet 6. When the dust concentration exceeds the range of dust concentration sensor 4, valves 3014 and 3015 switch, closing the sampling gas inlet 5 and sampling gas outlet 6, locking the high-concentration gas in the sampling tube 3021. Simultaneously, the channel to the dilution chamber 301 is opened. The zero gas in the dilution chamber 301 mixes with the high-concentration dust gas locked in the sampling tube 3021. The mixture is then aided by a pressurization device inside the dilution chamber 301. After homogenization, the dust concentration is detected by dust concentration sensor 4. If the concentration is within the range of the dust sensor, the actual dust concentration of the high-concentration dust gas can be counted according to the dilution ratio of the device. If the detected concentration still exceeds the range of dust concentration sensor 4, the gas is locked again, and a cleaning program is initiated. Valve 3012, valve 3017, and the pressurization device inside the dilution chamber 301 work together to introduce zero gas to expel the dust gas from the chamber, cleaning the dilution chamber 301. Then, the zero gas in the dilution chamber 301 mixes again with the dust gas in the sampling tube 3021. The detection of high-concentration dust gas is completed until the concentration can be correctly detected by the dust concentration sensor 4.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
