Abstract

The utility model relates to a hand-held GNSS (global navigation satellite system) receiver capable of collecting GIS (geographic information system) data. The receiver comprises a front casing, a front and rear casing sealing ring, a rear casing, a GPS reception antenna, a GPS module, a mainboard, a GPRS communication module, a battery assembly, an LCD screen and a battery connection stand. The receiver is characterized in that the an external structure composed of the front casing, the front and rear casing sealing ring, the rear casing, the battery assembly, the LCD screen and the battery connection stand enables the receiver to effectively meet standards of industrial water, dust and shock prevention; an industrial grade processor as high as 1Ghz is adopted by the mainboard, so that the operation speed of the receiver is effectively increased; and by using the hand-held receiver, a worker can collect, in a real-time manner, GIS data and image/audio data that are attached with real-time difference technical high precision position information in a field environment directly through a real-time communication function provided by the GPRS communication module and through data received by the GPS reception antenna and the GPS module.

Description

A kind of hand-held GNSS receiver that can gather the GIS data

Technical field

The utility model relates to the integrated handheld device of utilizing the Global Navigation Satellite System (GNSS) technology to carry out geography information (GIS) data acquisition.

Background technology

Mostly traditional global navigation satellite system GNSS (Global Navigation Satellite System) receiver is that mapping worker uses, and is mainly used in and obtains the atural object more specific location information; Usually, the GNSS receiver adopts the arm processor than low side, and memory size is low, and travelling speed is slower; Simultaneously traditional hand-held GNSS receiver industry three anti-aspect (dustproof and waterproof is shockproof) have defective; In addition, general GNSS receiver does not have communication function, accepts difference information like need, and the mobile phone that then must set up radio station or connecting band GPRS module communicates, and does not more have camera, microphone etc. to support the functional module of data acquisition; Along with socioeconomic fast development, the GIS Data Update faces big challenge, and is badly in need of novel, efficient, portable integration apparatus, upgrades to help the solving position attribution synchronization of data.

Summary of the invention

The utility model purpose is in order to overcome the deficiency of prior art, as: the miniaturization of equipment, the variation of technology, the enhancingization of function; And design a kind of small volume and less weight of providing, simple in structure, simple operation and the complete hand-held GNSS receiver of function for new-type GIS data acquisition plan.

For achieving the above object, the overall technological scheme that the utility model adopts is: structure adopts modular design, at limited structure space, each functional module is rationally utilized space arrangement by the zone, and strictly observes electrical specification.

The GNSS receiver enclosure divides fore shell and back cover, is provided with O-ring seal between fore shell and the back cover, and the external interface place is equipped with dust cap, can reach the purpose of waterproof, and shell adopts advanced ABS+PC material, plays antihunt action.

The built-in GPRS communication module of GNSS receiver has the real-time Communication for Power function, has guaranteed the GIS real time of data acquisition, and the bi-directional data of GPS receiving antenna capable of using and GPS module reception simultaneously realizes that the GPS real time differential is to improve bearing accuracy.

The GNSS receiver adopts outdoor color LCD screen, and light is had the half-reflection and half-transmission function, even but also operation under the high light in the open air.

Control main board adopts and moves processor up to the 1Ghz technical grade, cooperates the interior 512MByte of high capacity can effectively improve receiver travelling speed and acquisition speed.

Described GNSS receiver lithium battery and outside batteries housing combine the composition battery component, make things convenient for the battery installing/dismounting; Adopt the probe-type web member to be connected with the battery Connection Block on the receiver mainboard, can supply power to receiver by the effective and safe battery that lets, even also can not be out of shape at the back probe-type web member that works long hours with battery component; Features simple structure makes that the access of battery is convenient and swift; Adopt vast capacity 4200mAH lithium battery simultaneously, can make the machine continuous working more than 8 hours, battery component can be changed in real time, satisfies all weather operations.

The GPS receiving antenna increases filter unit to be installed simultaneously and has certain angle of inclination, a search of satellite number to greatest extent, and effectively improve signal to noise ratio (S/N ratio).

Because the technique scheme utilization, the utility model is compared like product and had following advantage: performance is higher, availability is stronger, the design of novelty Highgrade integration, reasonable in design; The placement of each functional module, the putting all of interface with easy to operate, changing simply is purpose; Design details is particular about; As shockproof dustproof, plug and play, thus have great practicality.
