With the development of ports, environmental pollution problems are inevitable. For example, dust pollution has become a major environmental problem that cannot be ignored in bulk ports. Surveys show that the atmospheric dust concentration values ​​of Chinese ports generally exceed the standard, especially in some old port areas. The dust fall in the central area is large and the pollution is serious. The dust pollution of some ports accounts for more than 50% of the total dust pollution in the city, constituting a serious environmental pollution. Port environmental problems have become a major problem faced by my country in building green ports. The prevention and control of port air pollutants has gradually become a key area of ​​concern in my country's air pollution control.

[0003] A bulk cargo port whose main cargo type is bulk coal. From the analysis of the sources of port pollutant emissions, it can be seen that dust pollution from bulk cargo operations in the yard is the main source of pollution. During loading, unloading, storage and transportation, coal powder and coal dust are easily naturally volatilized into the air, causing dust pollution. Especially in dry and windy environments, the dust phenomenon is more obvious. Therefore, a port service safety device with an alarm function and a method of using the same are proposed to solve the above problems. Summary of the invention

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-2 A port service safety device with an alarm function includes a dust multi-dimensional monitoring component 1, a monitoring and early warning management platform 2, an LED display screen 3, a spraying device 4 and a spraying and watering control system 5. The dust multi-dimensional monitoring component 1 includes a set of β-ray dust online monitors 101, a plurality of sets of light scattering dust online monitors 102 and a set of laser radar dust pollutant monitors 103.

[0026] Specifically, the spraying equipment 4 is a plurality of spray guns. According to the control area range, the monitoring system is divided into monitoring grid areas, and the grids are divided both inside and outside the field. The dust concentration is traced back to each independent grid area. When the grid exceeds the standard, the monitoring and early warning management platform 2 sends a spray signal to the spray sprinkler control system 5, directly controlling the spray gun of the grid to open, thereby realizing precise control of each grid.

[0027] Specifically, the monitoring and early warning management platform 2 includes a data map module, a data query module, a data analysis module, a statistical report module, an early warning alarm and linkage control module, a video monitoring module, a quality control module, an event processing module, an emission source information module, a compliance control module and an assessment notification module.

[0028] Furthermore, the data map module can realize the display, ranking, location information, data status information, equipment status information and other types of data of various monitoring equipment in real time, and display the air quality data and pollution event information of each grid in real time. At the same time, it supports the real-time concentration distribution and historical concentration distribution functions of various pollution factors in the entire port area; the combination of the data query module, the data analysis module and the statistical report module can realize the data query function within a certain period of grid, micro station and mobile station of various types, different precisions (minutes, hours, days, months, years), different factors (PM2.5, PM10, TSP, etc.), and display the data in the form of charts and export them in the form of reports.

[0029] Furthermore, the early warning alarm and linkage control module sets alarm rules to conduct data alarm statistics and inquiries, and can push them to grid members, enterprise management departments and other personnel in different roles through the monitoring and early warning management platform 2, mobile phone APP, WeChat, etc.; the video monitoring module can view the real-time video information of each monitoring point and review the historical video information. When a pollution incident occurs, it will automatically record and save the pollution process video within the set time.

[0030] Furthermore, the quality control module includes a data review submodule and a data retransmission submodule: the data review submodule sets data anomaly judgment rules, and the system automatically determines whether the data is valid, and then makes automatic screening for manual review. After manual confirmation, the statistical data is regenerated; the data retransmission submodule can actively send missing data requests to the device, thereby improving the comprehensiveness and accuracy of the data.

[0031] Furthermore, the event processing module implements the submission, query, and processing of pollution time; the emission source information module displays information related to emission sources in the grid to provide reference for decision makers; the compliance control module performs compliance analysis, query, and other operations by setting indicators such as the number of compliance days for the area and the reduction of pollutant concentration; the assessment notification module sets assessment targets for grids and personnel, and then automatically generates assessment results.

[0032] Specifically, the β-ray dust online monitor 101 and the light scattering dust online monitor 102 are used to calibrate the dust concentration at a fixed point. The laser radar dust pollutant monitor 103 obtains the concentration distribution information of dust pollutants at different heights by generating scattered light after the laser interacts with particulate matter and gaseous molecules. Through the combination of "1+1+N", the demand for real-time reflection of the dust concentration and its distribution in the terminal area can be realized.

[0033] Furthermore, the light scattering dust online monitor 102 can simultaneously measure TSP and PM in real time online. 10 、PM 2.5 , and can also be expanded to monitor NO 2 、SO 2 , CO and O 3 .

[0034] Specifically, the output end of the dust multi-dimensional monitoring component 1 is connected to the input end of the monitoring and early warning management platform 2, the output end of the monitoring and early warning management platform 2 is connected to the input end of the LED display screen 3, the output end of the monitoring and early warning management platform 2 is connected to the input end of the spray sprinkler control system 5, and the output end of the spray sprinkler control system 5 is connected to the input end of the spray equipment 4.

[0035] A method for using a port service safety device with an alarm function comprises the following steps:

[0036] S1. Use the β-ray dust online monitor 101 to monitor the dust at the site boundary, use the light scattering dust online monitor 102 to monitor the dust inside the site, and use the laser radar dust pollutant monitor 103 to monitor the dust pollutants in the wharf area;

[0037] S2, the dust multi-dimensional monitoring component 1 transmits the collected data to the monitoring and early warning management platform 2, and the monitoring and early warning management platform 2 performs data alarm statistics and inquiries according to the set alarm rules;

[0038] S3. When dust pollutants exceed the standard, the monitoring and early warning management platform 2 sends an early warning signal to the sprinkler control system 5. The sprinkler control system 5 links the secondary pump room and the control pump room to control the sprinkler equipment 4 in the yard, and issues the sprinkler instruction to the spray gun PLC. Spraying and dust reduction work is carried out through multiple spray guns to control the dust in the yard.

[0039] Specifically, the monitoring and early warning management platform 2 uses the dust precision control operation model to determine the weighted dust concentration in the grid area through intelligent integrated planning, and uses the inverse model of the Gaussian diffusion model to calculate the source strength of the unorganized emission source. The contribution rate of each grid source strength to the high-value detection concentration point is obtained according to the matrix model, and the contribution rate of the grid matrix to the pollution process is compared to realize intelligent identification of high emissions, thereby linking the sprinkler control system 5 to realize intelligent dust control.

[0040] In summary, the port service safety device with alarm function and its use method, by setting a dust multi-dimensional monitoring component 1 composed of a set of β-ray dust online monitors 101, multiple sets of light scattering dust online monitors 102 and a set of laser radar dust pollutant monitors 103, can directly reflect the dust concentration in the yard in real time, and can find out the dust generation points and dust generation rules in the yard. At the same time, it can also reflect the concentration at the yard boundary in real time, effectively reflect whether the environmental protection emission meets the standard, and can also directly reflect whether there is dust from outside the yard migrating into the yard and its concentration. There is no need to set up a large number of points in the yard, and only a few points are needed in the dock area. Just a few instruments are enough to meet the full-area coverage effect of dust monitoring, making the port's air pollution prevention and control more targeted, scientific and accurate, effectively improving the level of refined management of the port's atmospheric environment, truly realizing the precise prevention and control of air pollution, and solving the bulk cargo port whose main operating cargo is bulk coal. From the analysis of the source of pollutant emissions in the port, it can be seen that dust pollution from bulk cargo operations in the yard is the main source of pollution. During loading and unloading, storage and transportation, coal powder and coal dust are easily volatilized into the air naturally, causing dust pollution, especially in dry and windy environments, where the dust phenomenon is more obvious.
