[0082] Example 3, based on Examples 1-2, the present invention provides the following practical application effects and test data examples:
[0083] A. In a test at an industrial park, compared with the traditional manually controlled fog cannon equipment, the response speed of this system was shortened by about 50% when the pollution source suddenly appeared, from 3 minutes to 1.5 minutes to complete the spraying start. In the dust control test, the system reduced the PM10 concentration from 300 micrograms / cubic meter to 120 micrograms / cubic meter within 10 minutes, and the dust reduction efficiency reached more than 60%. Through automatic control and self-learning optimization, the system saved 30% of water resource usage and about 40 hours of manual operation time in a one-month test cycle;
[0084] B. In a simulated test environment, compared with traditional fog cannon equipment, within 10 minutes after the system was started at the same dust concentration, the concentration of PM2.5 and PM10 decreased by an average of 60%, while the traditional equipment decreased by 40%. In construction site applications, the system reduced water usage by about 30% within 1 month and increased spraying efficiency by 25%. In actual application in an industrial park, the system was able to start spraying measures within 1 minute during sudden pollution (such as increased smoke and dust emissions), which doubled the response speed of traditional systems. In urban road dust control projects, the system achieved remote automated control, reducing manual maintenance time by more than 70%, ensuring the continuous and stable operation of the equipment at night and in severe weather conditions;
[0085] In addition, based on the Internet of Things technology and edge computing, real-time fusion and processing of multiple sensor data is achieved, which greatly shortens the response time of pollution detection and governance. Edge computing technology enables the equipment to process data and execute control locally without relying on cloud computing, reducing data transmission delay. In the experimental scenario, compared with the traditional manual control method, the system can start spraying within 1-2 minutes of the pollution concentration change, which is more than 50% faster than the traditional method.
[0086] The system's automated operation and self-learning capabilities significantly reduce the need for manual operation and maintenance costs. The intelligent control algorithm combined with automated control devices can operate unattended, reducing the manpower investment in long-term operations. According to field application feedback, the application of the system on construction sites can reduce manual operation time by more than 50 hours per month and save about 30% of water consumption.
[0087] Traditional fog cannon equipment relies on timed spraying and manual operation and cannot be adjusted in real time according to the pollution situation. This system can dynamically adjust the spraying angle and intensity through intelligent analysis and adaptive control to achieve more refined governance. Under the same environment, the pollutant concentration of this system decreases more than 20% faster than traditional fog cannon equipment.
[0088] Other smart devices usually need to rely on cloud processing and have certain network delays, especially in areas with unstable networks. This system is based on edge computing and performs fast processing locally, ensuring the device's immediate response capability. In industrial area applications with unstable networks, the response delay of this system is reduced by about 30% compared to other devices, greatly improving processing efficiency.
[0089] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
