A kind of area measurement method based on GPS area measurement instrument
Technical field
The present invention relates to agriculturally area measurement method, be related specifically to area during harvester harvesting crops
Measuring method.
Background technology
The most agriculturally the harvesting of crops does not the most use manual harvesting mode, the substitute is with harvesting
Machine gathers in, and general peasant household other itself there is no harvester, and renting harvester is its harvesting, this
The most unavoidably can relate to both sides' dispute for harvesting area, so now for the consideration of this respect, now
Have on the market and much position, with GPS, the method measuring area, as disclosed in authorize on August 19th, 2012
The Chinese utility model patent of CN202403694U is just mentioned a kind of GPS farmland area measuring instrument, has
This measuring instrument, people only needs hand-held measuring instrument to enclose around farmland ridge one, just can be by the seat of GPS anchor point
Mark calculates the area of reality, and this method is being widely used in area measurement industry, but this
Hand-held there is also some problems, particularly harvesting vigorous season, the harvester harvesting task of a day
The busiest, but in order to measure area, have to hand-held measuring appliance and take a round along ridge, the most original
Time, hand-held measuring method just became more to lose time with regard in the case of not enough.
Summary of the invention
The technical problem to be solved is just to provide a kind of area measurement based on GPS area measurement instrument
Method, is installed on harvester become vehicular by the GPS area measurement instrument of hand-held, utilizes harvester to receive
Also measure the area of harvesting while cutting work, improve operating efficiency for harvesting work.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that a kind of based on GPS area measurement instrument
Area measurement method, with original hand-held GPS area measurement instrument as instrument, it is characterised in that: by hand
Holding formula GPS area measurement instrument and be arranged on a contractile expansion link top, described expansion link base hinge exists
On the rearview mirror of harvester, bail is set at expansion link base hinge and can clamp expansion link, measure face, soil
Time long-pending:
A) harvester is parked in land survey starting point, adjusts the contracted length of expansion link, extension elongation is adjusted
To ridge edge, rotate and adjust to level;
B) now utilize bail to be clamped by expansion bracket, fix expansion link, then set on GPS area measurement instrument
Putting this point is starting point;
C) harvester is started working, and the harvesting work of its first lap travels, during traveling along the area maximal margin of harvesting
Ensure that the distance between harvester side and ridge keeps unified;
D) suspend after arriving the starting point in step b after harvester travels one week along ridge edge, pack up on expansion link
GPS measuring instrument, set terminating point, thus this land area can be calculated according to the girth travelled.
Further, when harvester driving process runs into have barrier at ridge time, expansion link can be turned
Dynamic angle is got around follow-up the continuing of barrier and is sailed, and is just that the measuring instrument of hand-held is also wanted when running into barrier
To be got around, so the data almost difference that for from anchor point, both measure is little, and flexible
Bar is itself mounted within harvester rearview mirror rotating regulation.
Further, when running into irregular ridge edge, when harvester cannot press edge route running, can hand
Dynamic rotation adjusts expansion link, allows GPS area measurement instrument manually walk by edge route, some irregular soil
Ground, is particularly less than 90 degree at some dead angles, harvester cannot drive to position, dead angle, now may utilize
The expansion link rotated, the track route of manual mobile GPS measuring instrument.
Further, installing a printer in driving cab of harvester, described printer can be by GPS face
The data-printing document of the transmission of long-pending measuring instrument, the most a lot of GPS area measurement instruments can be direct according to unit price
Calculate harvesting expense, but during practical operation, this data are not necessarily believed by peasant household, so best side
Method is exactly first to tell peasant household's actual measurement area, then prints the document of charge according to area and unit price, this
Sample one first charge system and measurement data separates, because the land area that peasant household is to oneself gathering in itself
Oneself having substantially data at heart, if directly informing its expense, seeming, expense is opaque, and if will
Area and expense are separately informed, peasant household just can settle accounts with oneself, and next has had the document peasant household printed to increase
Degree of belief, reduces some unnecessary expense disputes, also improves the operating efficiency of harvesting work.
The GPS area measurement instrument of hand-held is being installed on harvester by advantages of the present invention, utilizes hand
The GPS area measurement instrument holding formula is installed on harvester become vehicular, so when harvester is in harvesting farming
During thing, can the harvesting route of first lap be placed on along ridge edge, so when having gathered in circle crops
Meanwhile, also measure the harvesting area having got well reality, eliminate conventional hand-held GPS area measurement instrument and also want artificial
Around the travel time of farmland one circle, improve operating efficiency for harvesting work.
Detailed description of the invention
Firstly the need of the top being installed to an expansion link on the market than more conventional hand-held GPS area measurement instrument
Portion, the reception antenna on television set that the structure of this expansion link is similar and old-fashioned, expansion link itself can extend
Or shortening, and the base portion of expansion link is ball shape, the base portion of ball shape embeds one with ball recess
Card lock ring, card lock ring is fixed on the rearview mirror of harvester, and the base portion of such expansion link is can be along random angle
Degree rotates, and similar and that reception antenna can rotate at television set top principle is consistent, the GPS of such vehicular
Area measurement instrument, with regard to basic installation, carries out area measurement the most in the following way:
A) harvester is parked in land survey starting point, adjusts the contracted length of expansion link, extension elongation is adjusted
To ridge edge, rotate and adjust to level, be so located at the GPS area measurement instrument of expansion link head
Anchor point is basic and harvester position consistency;
B) now utilize bail to be clamped by expansion bracket, fix expansion link, then set on GPS area measurement instrument
Putting this point is starting point;
C) harvester is started working, its first lap harvesting work along harvesting area maximal margin travel, i.e. edge and
The girth of ridge travels, and ensures that GPS area measurement instrument, so can be by error close to ridge edge during traveling
It is reduced to minimum;
D) suspend after arriving the starting point in step b after harvester travels one week along ridge edge, pack up on expansion link
GPS measuring instrument, set terminating point, thus this land area can be calculated according to the girth travelled.
When harvester driving process runs into have barrier at ridge time, card lock ring can be unclamped, will be flexible
Bar rotational angle, allows GPS area measurement instrument get around follow-up the continuing of barrier and sails, because when running into barrier just
The measuring instrument being hand-held is also to be got around, so the data that for from anchor point, both measure
Almost difference is little, and expansion link is itself mounted within harvester rearview mirror rotating regulation
When running into irregular ridge edge, when harvester cannot press edge route running, can hand rotation adjustment stretch
Contracting bar, allows GPS area measurement instrument manually walk by edge route, some irregular soil, and particularly one
Being less than 90 degree at a little dead angles, harvester cannot drive to position, dead angle, the now available expansion link rotated,
The track route of manual mobile GPS measuring instrument.
