Abstract

The utility model discloses a globe instrument for a computer, being used as an earth model, and the globe instrument can provide various global relevant information. Two axes are vertically crossed with an axial-center line at a globe center through an axial center extending line, one axis is a polar axis, the other one is a latitude axis for supporting the globe body of the globe instrument, the globe body can be freely rotated to discretional directions, and the two axes respectively drive a sensor through a gear driving system. When the globe body is rotated around the polar axis and the latitude axis according to some one direction, the sensors convert the rotation of the globe body into the correspondingly electric signal which is transferred to the computer, and after the computer processes and calculates the signal and confirms the represented area of the signal, the computer displays the relevant information of the area. The utility model has the advantages of large information quantity, quick display, convenient use, etc.

Description

Globe instrument for global information

The utility model relates to a kind of terrestrial globe of charged brain, promptly relates to a kind of terrestrial globe that can retrieve required regional useful information rapidly.Be applicable to occasions such as school, hotel, office, family, be used for retrieving and geographical relevant knowledge and other useful information.

The terrestrial globe of existing all size all is to be made of a spheroid on the fixed support that is supported on that is printed on world map.Its shortcoming is: limit because of being subjected to drawing, the quantity of information that can provide is very little, only be equivalent to the information that a world map can provide, various places Useful Information for the required understanding of people, grasp in the current social life, as meteorological, geographical, society and astronomical or the like information, then can't provide, cause many of great value information not propagated fully and to utilize.

The purpose of this utility model is, provide a kind of structure simple, make be easier to, terrestrial globe easy to use, that can retrieve the regions of the world useful information rapidly.

The purpose of this utility model takes following technical measures to realize: be provided with orthogonal two axles that intersect at the centre of sphere, wherein one is the pole axis that is supported on the support, and spheroid can freely rotate around pole axis; Another root axle is to be installed in the supported hole of underframe, and one end and support are fixed, and rotate with support.Like this, any point on the sphere of terrestrial globe just can optionally turn to a certain desired location.Pole axis one end makes through the axle rotation by gear, drives the longitude sensor; And the rotation of the latitude axle that is connected with support drives the latitude sensor.When terrestrial globe around mutually perpendicular two respectively when a certain direction is rotated, send corresponding electric signal by the sensor that they drove, input to computer by interface circuit, computer is handled after receiving the region signal of input, calculate, and, relevant this regional useful information that is stored in the computer is retrieved immediately shows as address signal.

Fig. 1 is a structural representation of the present utility model, Fig. 2 be the A of Fig. 1 to view, Fig. 3 is the structural representation of sensor.

In conjunction with the accompanying drawings structure of the present utility model and embodiment are described as follows:

Be fixed in the diaxon 3 and 6 on the spheroid 4, its axial line coincidence is also passed through the centre of sphere, it is the pole axis that is supported on the support, spheroid 4 can freely rotate around it, the end and the support 8 that are installed on the latitude axle 1 in the supported hole 12 of underframe 9 are connected, and the other end is by the input shaft 10e of gear 10a, shaft coupling 10f driving latitude sensor 102; The axes extending line of latitude axle 1 and pole axis axial line are orthogonal and meet at the centre of sphere, gear on the pole axis 6 is meshed with the gear of elasticity flexible axle 7 one ends, the gear of elasticity flexible axle 7 other ends is meshed with the gear on axle 2, pass the center pit of latitude axle 1 after the gear 10b that is meshed with it, shaft coupling 10c through axle 2, drive the input shaft 10d of longitude sensor 101.When spheroid 4 when arbitrary axis rotates, by gear train assembly by certain speed ratio pole axis 3 and 6 and the rotation of latitude axle 1 pass to separately

sensor

101 and 102 respectively, export corresponding electric signal by them and send computer 13 to through interface circuit 11.The signal Y corresponding latitude signal of latitude sensor 102 outputs, the corresponding spheroid 4 of signal X the relatively rotating and the composite signal that involve rotation of support 8 of longitude sensor 101 outputs around pole axis 3 and 6 around latitude axle 1, so longitude signal Z=X-Y, X, Y, Z are algebraic quantities in the formula, send computer 13 to by interface circuit 11, finish the calculating of following formula by computer 13, promptly obtain setting the longitude and the latitude signal in area.The elasticity pointer 5 that points to the centre of sphere is fixed on the underframe 9, the reference mark when rotating as globe sphere.

Warp, latitude sensor adopt shaft-position encoder.As adopt optical electric axial angle encoder, it can change the mechanical rotation of certain orientation into corresponding electric signal by opto-electronic conversion, and umber of pulse is directly proportional with the angle that is turned over, the electric signal of positive and negative corresponding rotation direction as the mechanical rotation of certain orientation, certain angle is changed into.Shaft-position encoder also can adopt contact shaft-position encoder, optical shaft encoder, Magnetic Sensor etc.

The course of work is as follows: in advance zero longitude on the terrestrial globe sphere and 1 latitude point are turned to the position of aiming at 5 indications of elasticity pointer, make computer this point be remembered and store as benchmark then.Again spheroid 4 is turned to required area and aim at elasticity pointer 5, sensor is promptly exported latitude signal Y and composite signal X, send computer 13 to by interface circuit, calculate longitude signal Z=X-Y by computer, as address signal, relevant this regional useful information that is stored in the computer is shown immediately.After rotating the globe with hand when aiming at elasticity pointer 5, unclamping hand, terrestrial globe is because the damping of meshing between axis hole mating surface and gear is promptly slack.

The utility model has the advantages that: by sensor the image of common tellurion, information storage capacity directly perceived and computer is big, computational speed is fast, the advantages such as demonstration is convenient together, thereby the information capacity that makes common tellurion has increased by tens times to several ten thousand times, common tellurion become that gas collection resembles, the knowledge information encyclopaedia grand ceremonies such as geographical, society and astronomy.
