And calculate the transformation matrix in plane design drawing internal coordinate and artwork between longitude and latitude；
Step 4, after mobile terminal enters closed area, scans the Quick Response Code Sign Board of equipment at one's side, obtains the equipment flat
Coordinate in the design drawing of face, according to transformation matrix longitude and latitude is converted into, and in the electronic chart after replacement current location is shown；
Step 5, according to the coding of target device, obtains the longitude and latitude of target device；
Step 6, according to current location and target device longitude and latitude, generates guidance path.
Quick Response Code Sign Board is the Quick Response Code Sign Board with directional information.
Quick Response Code Sign Board is the Quick Response Code Sign Board indicated with North and South direction.
The plane design drawing of acquisition is the electronic document of DWG forms.
Before encoding, the plane design drawing of DWG forms is converted into the plane design drawing of SVG forms.
When transformation matrix is calculated, the conversion between coordinate and longitude and latitude is not only considered, it is also contemplated that plane design drawing
Ratio, the anglec of rotation between artwork.
The beneficial effect that the present invention is reached：The present invention can be effectively overcome in large area photovoltaic plant operation maintenance process
In, attendant is being difficult to be accurately positioned the problem of photovoltaic plant individual equipment by navigator, is easy to attendant to look for
Equipment in photovoltaic plant.
Description of the drawings
Fig. 1 is electronic map match schematic diagram.
Specific embodiment
Below in conjunction with the accompanying drawings the invention will be further described.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
A kind of closed area accurate navigation method identified based on preset Quick Response Code, is comprised the following steps：
Step 1, obtains the plane design drawing of closed area；The plane design drawing is the electronic document of DWG forms, need to use instrument
