Description
Technical field
The utility model is related to a kind of measuring device more particularly to a kind of GPS land survey devices with alignment function,
Belong to land survey technical field.
Background technology
With China's urbanization, industrialized fast development, the bases such as the Rapid Expansion of town boundary and traffic, water conservancy
The gradual perfection of this construction, land patrol law-enforcing work become more and more important.Executing The Law While Managing Land device related to this is got over
To be more widely applied.With the application of GPS, GPS placement technologies have obtained extensively in measuring work
General application, and due to the fast development of computer technology and Internet technology, measuring instrument also therewith towards digitlization and
The direction of miniaturization is developed.At present, it then follows the computer communication interface of international standard has obtained in measuring instrument extensively
Application, can be realized the data communication of instrument and peripheral equipment using these computer communication ports, realize human-computer dialogue.Mesh
Before, it is applied there are no ripe in measuring device in the wild using GPS and prefabricated electronic map, survey especially in the prior art
Amount affects the precision of measurement there is still a need for using more original measuring device such as ruler tool etc..
It is held currently, widely used hand-held Executing The Law While Managing Land device is the soil GPS (Global Position System)
Although subtraction unit, measurement accuracy can reach Centimeter Level, still, since the GPS Executing The Law While Managing Land devices itself do not have measurement point
Alignment function, therefore, to improve measurement accuracy, it is necessary to be used cooperatively with the measurement point centralising device of auxiliary, otherwise measured deviation
It is larger, it is difficult to meet measurement request, realizes and measure purpose.The enforcing law of existing hand-held GPS land law enforcement device is as follows：It is first
Portable centering rod is first set up, after so that it is directed at measurement point, then the measurement point is carried out using GPS Executing The Law While Managing Lands device
Investigation law enforcement, so as to substantially meet the requirement of law enforcement precision.
For the law enfrocement official of urban land, during carrying out Executing The Law While Managing Land, need select by investigation plot or
Each inflection point of person's building passes through hand-held GPS land law enforcement device and corresponding measurement point centralising device, acquisition as measurement point
The corresponding geographic information data of each measurement point, you can obtain geographical location, floor space and the height in the plot or building
Etc. information.And for field land survey law enfrocement official, due to the limitation of current Executing The Law While Managing Land survey tool, to ensure soil
Ground law enforcement precision, it is necessary to carry the centering rod of stent-type, more accurate field measurement map could be obtained.Meanwhile being
Ensure the stability of centering rod and measures the accuracy of point location, it is real generally by the length and weight that increase centering rod
It is existing, and field work usually carries out on foot, Executing The Law While Managing Land personnel will also shoulder other than bearing required Executing The Law While Managing Land tool
More heavy centering rod so that physical demands is larger when Executing The Law While Managing Land personnel's field work, is easy to tired；And portable
It is very inconvenient, substantially increase the labor intensity of Executing The Law While Managing Land personnel.In addition, it is also very not square to carry out centering rod erection in the wild
Just, hack lever centering process is extremely slow, greatly influences Executing The Law While Managing Land efficiency.
In conclusion no matter for urban land law enforcement or field land survey, currently used handhold GPS
Executing The Law While Managing Land device needs the measurement point centralising device for additionally carrying the auxiliary such as centering rod because not having measurement point alignment function,
To increase Executing The Law While Managing Land difficulty, Executing The Law While Managing Land precision is reduced, meanwhile, also reduce Executing The Law While Managing Land efficiency.
For this purpose, someone has invented a kind of hand-held GPS land measuring device having both measurement point alignment function, such as application No. is
CN201010272037.1, a kind of entitled hand-held GPS land measuring device and method having both measurement point alignment function,
Including shell, the GPS receiver being packaged in shell, keyboard and display screen, the keyboard and display screen are being mounted on shell just
Face, which is characterized in that further include measurement point centralising device, the measurement point centralising device includes spirit level and miniature laser hair
Emitter, the spirit level include liquid holding device and the level(l)ing bubble that is packaged in liquid holding device, the spirit level and miniature laser hair
Emitter is fixedly mounted on the shell, and in the built-in aerial of laser beam and GPS receiver that is emitted of miniature laser transmitter
The heart is located along the same line, meanwhile, the laser beam that the miniature laser transmitter is emitted is vertical with liquid holding device.It is by level
Device, laser emitter and GPS receiver are integral by shell integration packaging, are sent out using the horizontal location and laser of spirit level
Emitter emits the synergistic effect of vertical laser light, to ensure GPS receiver built-in aerial center face target measurement point；Then
Target measurement point geographic information data acquisition is carried out using GPS receiver, completes the Executing The Law While Managing Land.The invention passes through existing
In some hand-held GPS land measuring devices, integration packaging spirit level, laser emitter are not necessarily to during realizing Executing The Law While Managing Land
The auxiliary of centering rod, you can quickly and accurately Alignment measuring point is independently completed the Executing The Law While Managing Land of the measurement point.
But when measurement, after the entire height change of instrument, forgets modification record and cause the error of measurement data still
In the presence of, therefore also need to further improve.
