Description
Technical field
The present invention relates to mapping and communication field, relate in particular to a kind of digital mapping method.
Background technology
The ground digital mapping is to utilize electronic total station or other measuring instruments to carry out the digital terrain data acquisition in the open air, under the support that becomes figure software, through the computer processed, obtains the method for digital topography map.At present, the digital mapping pattern generally adopts the field acquisition coordinate data, on paper, draws the landform sketch simultaneously, gets back to the indoor cable data transmission of carrying out, and coordinates extention on topographic map drawing software is according to the sketch drafting topographic map.Recently, although to have occurred with the bluetooth be the near field communication (NFC) of representative, but can not tackle the problem at its root.If adopt the data in real time of measuring total powerstation with upper type to be transferred in the computer, just need the scene to carry computer, and require computer and total powerstation together operation or closely operation; Therefore, the work pattern that this interior field operation is separated can not become figure in real time, becomes the figure time cycle long; Influence into figure efficient; If coverage of survey area is bigger, each group's surveying and mapping data can not gather in real time, will cause task to accomplish under specific circumstances; Simultaneously, field operation personnel's working strength is big, and the operating personnel can not get sufficient rest, causes operating efficiency low.
Summary of the invention
Technical problem to be solved by this invention provides the digital mapping method of a kind of ability remote live high efficiency of transmission coordinate data and sketch data.
For addressing the above problem, a kind of digital mapping method of the present invention may further comprise the steps:
(1) starts total powerstation, smart mobile phone I and receiving system respectively;
(2) said smart mobile phone I searches for the bluetooth communication equipment of said total powerstation, and connects with said total powerstation, and communications parameter is set;
(3) on said total powerstation, coordinate is set, and carries out the scene mapping, obtain describing X, Y, the Z coordinate data of landform; This coordinate data is stored, and pass through Bluetooth transmission to said smart mobile phone I;
(4) drafting is surveyed and drawn sketch and is saved as binary format on said smart mobile phone I, obtains the sketch data;
(5) with after the sketch data compression in the said step (4), through Short Message Service technology or general packet radio service technical transmission to said receiving system;
(6) Short Message Service technology or general packet radio service technical transmission to said receiving system are passed through in the compression of the coordinate data in the said step (3) back;
(7) said receiving system is drawn through topographic map drawing software, can obtain topographic map.
Receiving system in the said step (1) is note machine and host side; Said note machine links to each other with said host side through data wire.
Receiving system in the said step (1) is smart mobile phone II and host side; Said smart mobile phone II links to each other with said host side through data wire.
The present invention compared with prior art has the following advantages:
1, because the present invention is provided with the smart mobile phone of band Bluetooth function; And link to each other with receiving system through Short Message Service technology (SMS) or general packet radio service technology (GPRS); And because SMS or GPRS coverage are extremely wide, the not restriction of distance of transmission; Therefore, realized that real time remote carries out point-to-point data coordinates and sketch transfer of data, thereby greatly improved the operating efficiency of measurement-one-tenth figure; The needs of surveying and mapping data confidentiality have also been satisfied simultaneously.
2, because the receiving system among the present invention can in time send back to smart mobile phone to the map of having drawn, therefore, make the field operation survey crew can in time find to survey and draw mistake, in time do over again, thereby improved mapping efficient.
3, because the smart mobile phone among the present invention is easy to carry, after the data back host side, interior industry personnel draw in real time, make the field operation personnel need not carry out drawing work, therefore, have reduced field process personnel's working strength effectively, have improved operating efficiency.
4, adopt the present invention, can realize the transmission of a plurality of mapping small set of data, long-range receiving system receives, thereby guarantees that a plurality of mapping small set of data gather into figure in real time.
