Abstract
The invention provides an electronic return instrument which comprises a GPS chip, a memory, an arithmetic unit, a buzzer, a recording key and a clearing key. The GPS chip returns a current position to the arithmetic unit in real time. When a user presses the recording key, the memory records the current position returned by the GPS chip as a mark position. When the user presses the clearing key, the memory clears the mark position. The arithmetic unit carries out arithmetic on the current position returned by the GPS chip and the mark position in the memory in real time, acquires the distance between the current location and the mark position, and outputs drive current to the buzzer. The magnitude of the drive current is inversely proportional to the distance. The electronic return instrument can help people carrying out activities in an outdoor unfamiliar environment to easily return to a starting position, so that the people are not lost.
Description
Technical field
The present invention relates to electronic device field, especially, the electronics that relates to a kind of GPS of having positioning function returns to instrument.
Background technology
When people walk out of doors, while particularly walking in metropolis or field forest, extremely easily lost, from certain place, turn several branch roads, tend can not find start position more, for this problem, be to perplex people movable in foreign environment always, and do not have effective equipment to address this problem.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of electronics to return to instrument, this electronics returns to instrument can aid in people movable in outdoor foreign environment, easily turns back to origin, thereby avoids lost.
The technical solution adopted for the present invention to solve the technical problems is: this electronics returns to instrument and comprises GPS chip, storer, arithmetical unit, hummer, records key, clear key; Described GPS chip returns to current location in real time to described arithmetical unit; Described storer presses user the current location that record key time record is returned by described GPS chip, and position serves as a mark; Described storer is removed described mark position in the time that user presses clear key; Described arithmetical unit is done computing by the described mark position in the current location and the storer that are returned by described GPS chip in real time, obtain the distance between described current location and mark position, and to described hummer output driving current, the size of described drive current and the size of described distance are inverse ratio.
As preferably, described electronics returns to instrument and also comprises that one for amplifying the gain switch of described hummer volume, thereby make user too far away apart from origin, when hummer sound is too faint, can improve hummer volume by the mode of gain, until closer from origin time, then the elimination that will gain.
As preferably, described electronics returns to instrument and also comprises a display screen, for showing the distance between current location and the mark position that described arithmetical unit is obtained.
As preferably, described hummer has a switch, thereby guaranteeing safety, do not closed in not needing it to pipe.
Beneficial effect of the present invention is: adopt this electronics to return after instrument, when user is movable out of doors, as long as press and record key in reference position, record start position in described storer, after this voluntary activity arrives any place, will return time, as long as move along the increasing direction of hummer sound, can return to starting point.
Accompanying drawing explanation
Fig. 1 is the structural representation that this electronics returns to instrument.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment shown in fig. 1, this electronics returns to instrument and comprises GPS chip 1, storer 2, arithmetical unit 3, hummer 4, records key (not shown), clear key (not shown); Described GPS chip 1 returns to current location in real time to described arithmetical unit 3; Described storer 2 presses user the current location that record key time record is returned by described GPS chip 1, and position serves as a mark; Described storer 2 is removed described mark position in the time that user presses clear key; Described arithmetical unit 3 is done computing by the described mark position in the current location and the storer 2 that are returned by described GPS chip 1 in real time, obtain the distance between described current location and mark position, and to described hummer 4 output driving currents, the size of described drive current and the size of described distance are inverse ratio, that is be, current location range mark position is far away, and the drive current of hummer 4 is less, and the tweeting sound of hummer 4 is fainter.
Above-mentioned electronics returns to instrument, can also comprise that one for amplifying the gain switch of described hummer 4 volumes, thereby make user too far away apart from origin, when hummer sound is too faint, can improve hummer volume by the mode of gain, until closer from origin time, then the elimination that will gain.Described hummer 4 can also arrange a switch, thereby is closed in guaranteeing safely, not need it to pipe.
Above-mentioned electronics returns after instrument, when user is movable out of doors, as long as press and record key in reference position, record start position in described storer 2, after this voluntary activity arrives any place, will return time, as long as move along the increasing direction of hummer sound, can return to starting point.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
