Abstract
The invention discloses an engineering drawing-based navigation method which comprises the following steps of: 1. acquiring a GPS (Global Position System) navigation signal by a user through an external navigation device by using an electronic engineering drawing as a background map; 2. transmitting the GPS navigation signal to a computer immediately through Bluetooth; 3. analyzing the signal in real time; and 4. drawing navigation information with an engineering drawing coordinate system in engineering drawing software and carrying out voice broadcasting and displaying so as to realize the real-time navigation and location. The engineering drawing-based navigation method has the beneficial effects that the user can conveniently obtain navigation information of a coordinate system same as a design drawing by using the engineering design drawing as the background map, the purpose of applying the existing navigator to the engineering field is realized, and the problem of compatibility of spherical coordinates of a WGS84 (World Geodetic System) ellipsoid and coordinates in the existing engineering field is solved; and the engineering drawing-based navigation method is widely applied to industries such as petroleum, geophysical prospecting and electric power.
Description
Technical field
The present invention relates to a kind of air navigation aid, belong to field of navigation technology based on engineering drawing.
Background technology
In industries such as the hydrology, geology, physical prospecting, oil, water conservancy, electric power, archaeologies, the engineering staff often needs to carry out operation to the scene, runs into the situation of topographic condition more complicated, needs the navigating instrument navigation.
Existing navigation is based on the navigational system of existing electronic chart, application has following limitation in the engineering field: the first, map of navigation electronic is the file that is encapsulated in set form in the navigation software, and the navigation of engineering field more need be that electronic chart navigates with the engineering drawing; The second, the electronic chart of tradition navigation is based on the spherical co-ordinate of WGS84 ellipsoid, in China, Beijing 54 coordinate systems, Xi'an 80 coordinate systems, local coordinate system are generally used in the engineering field, two cover coordinate system disunities, above-mentioned defective causes traditional navigator to be subjected to certain limitation in the application of engineering industry.
Summary of the invention
The object of the present invention is to provide a kind of air navigation aid, existing navigating instrument can be applied to the engineering field, the compatibling problem of the spherical co-ordinate of solution WGS84 ellipsoid and the coordinate in existing engineering field based on engineering drawing.
The objective of the invention is to be achieved through the following technical solutions: a kind of air navigation aid based on engineering drawing, it comprises following steps:
(1), the user is background map with electronic engineering drawing, gathers the GPS navigation signal by external navigator;
(2), in time the GPS navigation signal is sent in the computer by bluetooth;
(3), signal real time parsing: the navigation software in the computer receives gps signal in real time, parse navigation information, utilize seven parameters to carry out coordinate conversion, convert the WGS84 coordinate conversion of GPS navigation signal to the engineering drawing coordinate, obtain having the navigation information of engineering drawing coordinate system;
(4), the navigation information that will have an engineering drawing coordinate system is plotted in the engineering painting software, the lang sound of going forward side by side is reported also and is shown, realizes the real-time navigation location.
Described engineering drawing coordinate comprises Beijing 54 coordinate systems, Xi'an 80 coordinate systems and local coordinate system.
Beneficial effect of the present invention is: the user can be easily with project blue print map as a setting, obtain navigation information in real time with the design drawing same coordinate system, realized existing navigating instrument is applied to the purpose in engineering field, solve the compatibling problem of the coordinate in the spherical co-ordinate of WGS84 ellipsoid and existing engineering field simultaneously, be widely used in industries such as oil, physical prospecting, electric power.

As Fig. 1, a kind of air navigation aid based on engineering drawing, it comprises following steps:
(1), the user is background map with electronic engineering drawing, gathers the GPS navigation signal by external navigator;
(2), in time the GPS navigation signal is sent in the computer by bluetooth;
(3), signal real time parsing: the navigation software in the computer receives gps signal in real time, parse navigation information, utilize seven parameters to carry out coordinate conversion, convert the WGS84 coordinate conversion of GPS navigation signal to the engineering drawing coordinate, obtain having the navigation information of engineering drawing coordinate system;
(4), the navigation information that will have an engineering drawing coordinate system is plotted in the engineering painting software, the lang sound of going forward side by side is reported also and is shown, realizes the real-time navigation location.
Described engineering drawing coordinate comprises Beijing 54 coordinate systems, Xi'an 80 coordinate systems and local coordinate system.
Described engineering painting software comprises common AutoCAD mapping software, and the navigation signal that obtains is drawn out by AutoCAD, and the present invention also is a kind of air navigation aid based on AutoCAD software.
