The solution to the above-mentioned prior art is as follows: Patent No. 201911183633.X discloses an environmental air quality monitoring system based on big data, which includes a user end and a field end, and the user end realizes data interaction with the field end through communication networking; the field end includes several monitoring nodes, and the monitoring node integrates an MCU control unit and a sensor group. The MCU control unit is electrically connected to the power module, the wireless communication module, the GSM module and the GPS module. The GPS module is used to locate the monitoring node, the GSM module is used for the monitoring node to send data through the network, and the wireless communication module is used to control the monitoring node to work through the wireless network. The air quality of each area is monitored by the distributed monitoring nodes, and the data of each node is uniformly uploaded to the user end through the wireless network. The air quality problem can be queried in real time through the user end, which is more convenient to use.
[0003] In the actual work process, the applicant found that the above-mentioned prior art did not effectively monitor the urban environment, that is, there is an urgent need to provide a monitoring system suitable for the urban environment. Summary of the invention
[0004] The purpose of the present invention is to provide an environmental air quality data acquisition and transmission system using a monitoring device, which is intended to automatically acquire and transmit air quality data for an urban environment.
[0005] The present invention provides an environmental air quality data collection and transmission system using a monitoring device, comprising an urban public air quality data collection unit distributed around a city, a miniature air quality sensor unit distributed on street lamps inside the city, and an air quality data transmission unit; the air quality data transmission unit comprises a first data receiving and storing module, a second data receiving and storing module, and a data analysis module, the first data receiving and storing module is electrically connected to the urban public air quality data collection unit, the second data receiving and storing module is electrically connected to the miniature air quality sensor unit, and the data analysis module is electrically connected to the first data receiving and storing module and the second data receiving and storing module respectively;
[0006] The monitoring ranges of the adjacent urban public air quality data collection units overlap, the data analysis module receives the urban surrounding air quality data values of the first data receiving and storing module in real time, and the second data receiving and storing module stores the urban internal air quality data values of the micro air quality sensor unit;
[0007] When the air quality data value around the city is greater than the preset air quality data threshold, the data analysis module starts to receive the air quality data value inside the city from the second data receiving and storing module;
[0008] When the urban internal air quality data value is greater than a preset air quality data threshold, if it is at night, the brightness of the street lamps in the collection area corresponding to the micro air quality sensor unit is controlled to change, and the brightness of the street lamps increases with the increase of the difference between the urban internal air quality data value and the preset air quality data threshold; if it is daytime, the display screen in the collection area corresponding to the micro air quality sensor unit is controlled to display the air quality data in the area.
[0009] Furthermore, the urban public air quality data collection unit is a small standard automatic air quality station; and the micro air quality sensing unit is a micro air quality monitoring station.
[0010] Furthermore, the coverage area of the micro air quality sensor unit is not less than 50 meters.
[0011] Furthermore, the urban public air quality data collection units are arranged at both ends of each urban main road.
[0012] Furthermore, when the air quality data values around the city are greater than a preset air quality data threshold, the data analysis module begins to receive the stored city internal air quality data values and real-time city internal air quality data values of the preset time length from the second data receiving and storage module.
[0013] Furthermore, the air quality data values around the city and the air quality data values inside the city are both average values of air quality data values within a certain period of time.
[0014] Further, a certain duration is 5 to 15 minutes.
[0015] Furthermore, a relationship between the city's internal air quality data value and a preset air quality warning score is established to determine the air quality warning level of the city's internal air quality data value, and the air quality warning level of the corresponding area is sent to the regulatory department.
[0016] Furthermore, the air quality warning level includes gradually increasing light pollution level, moderate pollution level, heavy pollution level and severe pollution level. When it is above the heavy pollution level, the air quality data in the area collected by the micro air quality sensor unit is played in a loop through the player both at night and during the day.
[0017] Furthermore, it also includes a historical trend unit, which is respectively connected to the first data receiving and storage module, the second data receiving and storage module and the display screen, the historical trend module extracts the environmental air quality data of the monitoring points from the first data receiving and storage module and the second data receiving and storage module, and the historical trend module generates an environmental trend graph based on the environmental air quality data, and sends the environmental trend graph to the display screen for display.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] By cooperating with the urban public air quality data acquisition unit and the micro air quality sensor unit, the ambient air quality around the city and inside the city can be detected simultaneously, and data can be acquired in a timely and effective manner; further, the data analysis module in the present invention receives the air quality data values around the city from the first data receiving and storage module in real time, and when the air quality data values around the city are greater than the preset air quality data threshold, the data analysis module starts to receive the air quality data values inside the city from the second data receiving and storage module, so that the data analysis module first processes the air quality data values around the city, and only analyzes the air quality data values inside the city when an abnormality occurs, thereby reducing the amount of data analysis and improving the accuracy of the analysis. BRIEF DESCRIPTION OF THE DRAWINGS
[0020] Figure 1 The present invention is a flowchart of an environmental air quality data collection and transmission system using a monitoring device according to an embodiment of the present invention. DETAILED DESCRIPTION
[0021] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0022] like Figure 1As shown, the present invention provides an environmental air quality data collection and transmission system using a monitoring device, including urban public air quality data collection units distributed around the city and miniature air quality sensor units and air quality data transmission units distributed on street lamps inside the city; wherein the urban public air quality data collection unit is a monitoring device in the prior art, and the urban public air quality data collection unit has its own power supply, such as being equipped with a solar panel, such as a small standard air quality automatic station; the arrangement of urban public air quality data collection can be various, as long as the air quality data collection around the city can be completed, for example, the urban public air quality data collection unit is arranged at both ends of each urban main road; the miniature air quality sensor unit is a monitoring device in the prior art, such as a miniature air quality monitoring station, and the miniature air quality sensor unit can have its own power supply, such as being equipped with a solar panel, or can use the power supply of street lamps; the coverage area of the miniature air quality sensor unit is not less than 50 meters;
[0023] The air quality data transmission unit includes a first data receiving storage module, a second data receiving storage module and a data analysis module, the first data receiving storage module is electrically connected to the urban public air quality data acquisition unit, the second data receiving storage module is electrically connected to the micro air quality sensor unit, and the data analysis module is electrically connected to the first data receiving storage module and the second data receiving storage module respectively;
[0024] The monitoring ranges of the public air quality data collection units in adjacent cities overlap, the data analysis module receives the air quality data values of the surrounding areas of the city from the first data receiving and storing module in real time, and the second data receiving and storing module stores the air quality data values of the inner city of the micro air quality sensor unit;
[0025] When the air quality data value around the city is greater than the preset air quality data threshold, the data analysis module starts to receive the city's internal air quality data value from the second data receiving and storing module, so that the data analysis module first processes the city's surrounding air quality data value, and only analyzes the city's internal air quality data value when an abnormality occurs, thereby reducing the amount of data analysis and improving the accuracy of the analysis; further, in order to improve the analysis accuracy of the city's internal air quality data value, the present invention uses the data analysis module to start receiving the city's internal air quality data value and the real-time city's internal air quality data value stored for a preset time period of the second data receiving and storing module, that is, by analyzing the stored city's internal air quality data value, the process and trend of the city's internal air quality data change can be analyzed, so that the data is more comprehensive, avoiding only analyzing the real-time city's internal air quality data value, and failing to effectively obtain the overall state of the city's internal air quality change;
[0026] When the air quality data value inside the city is greater than the preset air quality data threshold, if it is at night, the brightness of the street lamps in the collection area corresponding to the micro air quality sensor unit is controlled to change, and the brightness of the street lamps increases with the increase of the difference between the air quality data value inside the city and the preset air quality data threshold; if it is during the day, the display screen in the collection area corresponding to the micro air quality sensor unit is controlled to display the air quality data in the area; wherein, the change in street lamp brightness serves as an air quality display module, which, on the one hand, allows people to know the general state of the air quality here through the change in brightness; on the other hand, it can provide relatively high brightness in the current haze weather to improve the visibility of traffic here.
[0027] In order to reduce the amount of data analysis and ensure the accuracy of the data, the air quality data values around the city and the air quality data values inside the city in the present invention are the average values of the air quality data values within a certain period of time, so as to avoid the problem of abnormality easily occurring when randomly selecting data within a certain time. The certain period of time is 5 to 15 minutes.
[0028] In order to automatically determine the air quality warning level, the present invention establishes a relationship between the value of the air quality data within the city and the preset air quality warning score, determines the air quality warning level of the air quality data value within the city, and sends the air quality warning level of the corresponding area to the regulatory department. The air quality warning level includes gradually increasing light pollution level, moderate pollution level, heavy pollution level and severe pollution level. When it is above the severe pollution level, the player is used at night and during the day to loop the air quality data in the area collected by the micro air quality sensor unit. Among them, the air quality is divided into 6 levels, level 1: air pollution index ≤ 50 excellent; level 2: air pollution index ≤ 100 good; level 3: air pollution index ≤ 150 light pollution; level 4: air pollution index ≤ 200 moderate pollution; level 5: air pollution index ≤ 300 severe pollution; level 6: air pollution index> 300 severe pollution.
[0029] The present invention also includes a historical trend unit, which is respectively connected to the first data receiving and storage module, the second data receiving and storage module and the display screen. The historical trend module extracts the environmental air quality data of the monitoring points from the first data receiving and storage module and the second data receiving and storage module. The historical trend module generates an environmental trend graph based on the environmental air quality data and sends the environmental trend graph to the display screen for display.
