Design And Implementation Of Map Service For Real-time Construction Coverage Monitoring

Construction coverage is a common technical requirement in the process of mechanical construction.Taking road construction as an example,there are strict requirements for the layered laying of the roadbed and the number of compactions for each layer.Traditionally,manual methods are used to check the construction coverage.large error.With the development of high-precision positioning technology and Internet of Things technology,the location information of construction equipment during construction can be collected and transmitted in real time,so that the construction coverage can be estimated based on the location information of construction equipment and related parameters.Map is a common visualization medium,which can intuitively reflect the spatial distribution of the objects that users care about.Map is not only a simple visualization of spatial data,but also in the display of data description information,quick preview of the actual content of data,and the relationship between data and its spatial location.There are also advantages in aspects such as the visual representation of.Using the Internet of Things technology to collect the location information of construction vehicles in real time and transmit it to the server,calculate the construction coverage area in real time through the location information and related construction parameters,and finally display the construction coverage in the form of map services has become a new method in the current construction field.Focusing on "map service for real-time construction coverage monitoring",this thesis analyzes the research status of map service and real-time monitoring of the Internet of Things,and studies the key technologies.(1)The construction area is divided into several units,and each unit is divided into regular grids according to the requirements of construction coverage monitoring accuracy,and the values of the grids corresponding to the overlapping areas are accumulated through the superposition calculation of the construction coverage area and the construction area.To characterize the degree of construction coverage.Multiple units are conducive to multi-device collaboration,and finally multiple units are stitched together,and the values corresponding to the grid are converted into color values to realize the visualization of the construction coverage of the entire construction area;(2)For the collection and processing of real-time construction monitoring data,first analyze and design the construction monitoring data format and transmission data parameter type,and use the Netty framework to realize the construction monitoring data collection,and then implement the Netty framework’s custom Handler method to complete the processing of real-time construction monitoring data.Including the conversion of transmitted JSON data into location information in the construction process,construction coverage data based on the location information in the construction process and combined with the construction surface data algorithm;(3)Integrating the release of the map service of construction coverage monitoring,by integrating real-time construction monitoring data with map information,the coverage of the construction area can be displayed more intuitively,providing more accurate data support for construction management and decision-making.The real-time construction monitoring data is converted into Geo TIFF format,and the service is provided to users through map service publishing.Experiments have proved that by collecting the location information of construction equipment and combining the equipment construction parameters,the construction coverage area can be calculated in real time,and the construction coverage area can be released through map services,which can realize the map visualization monitoring of construction coverage.
