Abstract

The utility model provides a circuit with a home pointing function. The circuit can drive a pointer to point to the direction of a home all the time, and is formed by a control core MCU (Micro-programmed Control Unit) (1), a GPS (Global Position System) module (2), a geomagnetic sensor module (3), an input module (5), a pointer display module (5) and a system power supply module (6); and a position coordinate of the home is set by one key through the input module (4) so that the circuit is a good helper for a stray to find the home.

Description

A kind of circuit that the man function of finger is arranged

Technical field

The present invention relates to a kind of brand-new design of electronic circuits, specifically a kind of circuit that the man function of finger is arranged.

Background technology

Some people has often forgotten tame position and direction in the society after going out, thereby the family of having wandered away back not, finds house in order to help the stray, and the spy has invented has the circuit that guides the direction of going home to the stray.

Summary of the invention

Technical problem to be solved in the utility model is: invented a kind of circuit that refers to tame function that has, be transplanted on the different carriers and formation had the various products that guide the stray that goes out to go home.

The technical scheme that its technical matters that solves the utility model adopts is: circuit design is control core MCU(1), GPS module (2), geomagnetic sensor module (3), load module (4), pointer display module (5), system power supply module (6).It is characterized in that: control core MCU(1) link to each other with GPS module (2), geomagnetic sensor module (3), load module (4), pointer display module (5), system power supply module (6), system power supply module (6) and control core MCU(1), GPS module (2), geomagnetic sensor module (3), load module (4), pointer display module (5) link to each other.By load module (4) core MCU(1 is controlled in coordinate position input in destination) in, GPS module (2) and geomagnetic sensor module (3) are sent to control core MCU(1 to the data of measuring) in carry out analyzing and processing, data are after treatment given pointer display module (5), make pointer point to orientation, place, destination all the time, system power supply module (6) is given each module for power supply.

Acting as of each module:

(1), data storage processing, instruction issue.

(2), measure current position coordinates information.

(3), measure the drift angle data.

(4), input data and control.

(5), indication orientation, place, destination.

(6), provide power supply for system.

The beneficial effects of the utility model are, circuit has a key assignments function, press this key when leaving home to go out, the present position namely is set to unique coordinate points of family, after going out no matter in where, the finger man pin that liquid crystal type or high brightness paster LED formula form can point to the direction of family all the time, allows possessor's NEVER GET LOST; Circuit design is simple, powerful, and volume is small and exquisite, and power consumption is extremely low, can be designed to the wrist strap product separately, also can be placed on the articles for use such as crutch, wheelchair, is the excellent helper that the stray seeks house.

Description of drawings

Accompanying drawing 1 is enforcement structural representation of the present utility model.

Control core MCU(1 among the figure), GPS module (2), geomagnetic sensor module (3), load module (4), pointer display module (5), system power supply module (6).

Embodiment

With reference to description of drawings the utility model is done following concrete detailed description: as shown in Figure 1, the utility model is by control core MCU(1), GPS module (2), geomagnetic sensor module (3), load module (4), pointer display module (5), system power supply module (6) form; It is characterized in that: control core MCU(1) link to each other with GPS module (2), geomagnetic sensor module (3), load module (4), pointer display module (5), system power supply module (6), system power supply module (6) and control core MCU(1), GPS module (2), geomagnetic sensor module (3), load module (4), pointer display module (5) link to each other.

Enforcement recited above only is that preferred implementation of the present utility model is described; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; common engineering technical personnel make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all has been documented in claims.

Claims

1. one kind has the circuit that refers to tame function, by control core MCU(1), GPS module (2), geomagnetic sensor module (3), load module (4), pointer display module (5), system power supply module (6) form; It is characterized in that: control core MCU(1) link to each other with GPS module (2), geomagnetic sensor module (3), load module (4), pointer display module (5), system power supply module (6), system power supply module (6) and control core MCU(1), GPS module (2), geomagnetic sensor module (3), load module (4), pointer display module (5) link to each other.
