Embodiment Construction

[0030] The invention will be further described in detail below in conjunction with the accompanying drawings of the specification.

[0031] Such as figure 1 Shown is the data model for configuring map symbols. Sensor devices are designed through dotted map symbols on the GIS map. The organization of the primitive data of traditional dotted map symbols only relies on the primitives instead of establishing and The connection of sensor variables. In order to realize the visualization of sensor device data, referring to the configuration principle, the communication protocol needs to be introduced in the map symbol design process to establish the relationship with the communication server for real-time data acquisition. At the same time, according to the configuration method, the corresponding mapping method is established according to the sensor data type , Drive the change of the visual variable of the corresponding image element, and realize the graphical change driven by the scri...

Abstract

The invention discloses a configuration map symbol design method. The method comprises two phases and is characterized by introducing a configuration method in the real-time monitoring field to map symbol modeling, designing a configuration map symbol data model and realizing organization of map symbol data and sensor data; from the real-time acquisition angle of the sensor data, establishing a parsing logic of the sensor data and coupling the parsing logic with a drawing interface of the map symbol to form a logic model of a configuration map symbol; and verifying feasibility of the map symbol in a GIS software platform. The method fuses the principle of configuration into the design of the map symbol and manages sensor equipment in the map symbol form, and can solve the problem that a conventional map symbol cannot realize real-time visualization of the sensor data in GIS.

Description

Technical field [0001] The invention relates to a design method for configuration map symbols, and belongs to the technical field of geographic information visualization expression. Background technique [0002] With the integration and development of the Internet of Things and GIS, sensor equipment, as the most basic equipment unit of the Internet of Things, is located in all corners of various regions. It is used to collect data in real time and continuously upload massive sensor equipment data to the monitoring management system. Accurate and efficient information methods are presented to equipment monitors. A large number of sensor devices connected to the Internet of Things have spatial location information. The location of such sensor devices and other derived information are expressed by geographic information. This is the most direct and effective combination of the Internet of Things and geographic information. [0003] Map symbols are the basic language of GIS maps and t...
