Detailed Description
For a further understanding of the invention, reference will now be made to the following examples, which are provided to illustrate further features and advantages of the invention, and are not intended to limit the scope of the invention as set forth in the following claims.
As shown in fig. 1, the new energy open-air infrastructure field environment monitoring system of the invention comprises an unmanned aerial vehicle, a computer processing module and an alarm module; the unmanned aerial vehicle is provided with an information acquisition module; the computer processing module comprises an information processing module and an information output module.
The unmanned aerial vehicle is used for cruising at a new energy open-air infrastructure site, and acquiring local environment information through the information acquisition module, wherein the local environment information comprises image information, temperature information, noise information and dust samples; specifically, image information, temperature information and noise information of the construction site environment are collected through the information collection module and transmitted to the information processing module, dust samples in air of the local construction site are collected through the information collection module, and dust components are subsequently detected manually.
The information processing module compares the received noise information with a noise threshold value, compares the received temperature information with a temperature threshold value, and starts the alarm module to inform workers of site construction if the noise is higher than the noise threshold value or the temperature is higher than the temperature threshold value; otherwise, processing the received image information, extracting the position of the sound generating equipment and the position of the heating equipment from the image information, generating a three-dimensional space model of the construction site, and carrying out numerical simulation prediction on the atmospheric variation trend of the construction site by combining the collected noise information and the temperature information by using a numerical calculation method to obtain a simulation prediction result.
And the information output module is used for outputting the simulation prediction result obtained by the information processing module.
And the alarm module is used for giving an alarm when the noise is higher than the noise threshold value or the temperature is higher than the temperature threshold value and giving an alarm when pollutants in the dust sample exceed the standard.
Wherein, the camera should have high definition; a resolution of not less than 4k is used. The temperature sensor has the measurement precision requirement that the change of the temperature fluctuation exceeding 0.5 ℃ can be quickly detected; noise sensors require precision to quickly detect changes in noise fluctuations beyond 7 dB.
A single unmanned aerial vehicle is only responsible for gathering an environmental information, can reduce unmanned aerial vehicle repacking cost like this, even certain unmanned aerial vehicle damages and does not influence the collection of other environmental information yet, and the most important can use the parallel programming framework, reduces the degree of difficulty of programming. The number of unmanned aerial vehicles used for each information acquisition is determined by the size of a construction site. Be responsible for gathering the unmanned aerial vehicle of dust sample and add the control circuit integrated module and the response dust collection system's that use the singlechip as the core quality sensor at the repacking in-process, deposit the judgement analysis program that detects dust collection system quality change in advance in the singlechip, set for collection system's quality or capacity information in the procedure for judge whether dust fills with, if fill with then return through program control unmanned aerial vehicle and set for the position.
As shown in fig. 2, the method for monitoring the environment of the new energy open-air infrastructure site of the invention comprises the following specific implementation processes:
firstly, adopt unmanned aerial vehicle to gather job site environment's image information, noise information, temperature information and gather the dust sample.
Then, the unmanned aerial vehicle transmits the acquired image information, the acquired noise information and the acquired temperature information back to the information processing module. The noise value and the temperature value are judged in the information processing module, if at least one index in the noise or the temperature exceeds the corresponding threshold value, the alarm module is directly started to remind workers to stop construction, and potential safety hazards in the construction environment are checked or the construction flow is adjusted; and if the noise and the temperature do not exceed the corresponding threshold values, processing image information, extracting the position information of the sound generating equipment and the position information of the heating equipment by adopting an image processing technology, generating a three-dimensional space model of the construction site, and carrying out numerical simulation prediction on the atmospheric change trend of the construction site by combining the collected noise information and the collected temperature information by using a numerical calculation method to obtain a simulation prediction result.
In a calculation mode of predicting the atmospheric change trend of a construction site by numerical simulation, the method does not adopt a common multi-physical-field coupling calculation mode of a sound field, a temperature field and a flow field, because the calculation mode has higher accuracy but longer calculation time, and cannot meet the requirement of coping with the constantly-changing environment of the construction site; therefore, in order to simulate and predict the change process of the environment quickly and accurately, the invention adopts the calculation flow shown in fig. 3 in the aspect of numerical simulation prediction:
(1) Constructing a three-dimensional space model of a construction site through image information and carrying out grid division;
(2) Setting boundary conditions and related physical property calculation parameters of sound field calculation in a three-dimensional space model;
(3) Calculating the steady sound field distribution by adopting an absorption attenuation model to obtain pressure distribution; the control equation in the process uses a pressure acoustic equation (namely in the form of Helmholtz equation) in a frequency domain;
(4) Setting initial conditions, boundary conditions and related physical property calculation parameters of fluid flow and heat transfer in a three-dimensional space model;
(5) Taking the pressure distribution obtained in the step (3) as a volume force calculated by a flow field, wherein the heating equipment is equivalent to a heat source at a known space geometric position in the calculation; performing numerical calculation simulation on the coupled flow field and the temperature field, wherein a flow field control equation adopts a continuous equation, an N-S equation (adding a volume force term) and an energy equation (adding a heat source term); the heat transfer equation adopts a transient fluid heat transfer equation;
(6) And (5) outputting a numerical calculation simulation result which is used as a basis for researching and analyzing the influence on the environment in the construction process and provides reference for optimizing the construction flow at the later stage.
To explain further: because the natural flow speed in the atmospheric environment is very slow, the capability of improving the heat transfer rate is far inferior to the condition that forced convection exists, and a local area with larger pressure gradient does not exist; therefore, the background flow field is approximately considered to be stable, the initial speed is zero, and the pressure is atmospheric pressure; and in addition, the numerical simulation prediction is carried out, namely, if the sound generating equipment and the heat generating equipment which exceed a preset threshold value do not exist in the construction environment, the flow driving force in the atmospheric flow field is approximately considered to be from the gravity and the sound disturbance of the sound generating equipment.
And finally, outputting the prediction result by an information output module to provide reference for workers, and adjusting the construction process and the progress by the workers according to the prediction result.
When the above-mentioned work flow goes on, unmanned aerial vehicle constantly gathers dust sample at the flight in-process. After the dust sample collecting device is filled, the unmanned aerial vehicle automatically sets a fly-back set position according to a program and takes the collected dust sample down by a worker for component inspection to obtain an inspection result; if the inspection result shows that the pollutants in the dust sample exceed the standard, the alarm module is directly started to remind workers of stopping construction; and if the pollutants in the dust sample do not exceed the standard, storing the detection result.
According to the construction method, the unmanned aerial vehicle is used for collecting real-time information of a construction site, the computer processing module is used for rapidly identifying local environment change and safety risk caused by construction, and feedback is made in time to help constructors to adjust schemes, so that potential damage caused by the local environment change is eliminated. The system can effectively enhance the information acquisition capacity of the new energy open-air infrastructure construction process, ensure the safety of constructors, timely adjust the construction flow, reduce the pollution to the local environment and eliminate the irreversible damage to the local environment.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
