Description

A kind of device recovering starting point

Technical field

This utility model belongs to GIS-Geographic Information System field, has writing function recover the device of starting point particularly to a kind of.

Background technology

Existing direction giving system is required for greatly online, has electronic chart and just can complete the task of showing the way. Owing to city is in continuous development, urban construction often changes, it is necessary to real-time update electronic chart. But also there is the inaccurate problem of electronic chart, the mistake that shows the way now often occurs, it is impossible to arrive at the destination. In or objective bad at network is clear and definite not, user is often got lost, and the waste plenty of time can not find destination.

Not by the place of electronic chart record, as not having the ground such as the place of road, grassland, desert, sea, field, this kind of direction giving system cannot play effect. On the other hand, this navigation system is general all more complicated, troublesome poeration.

Referenced patent document CN202196402U discloses a kind of direction giving system, this system includes input equipment, controls device and display device, controlling device to include controlling module, message processing module and GIS client, message processing module includes fix information processing module and multidate information processing module. Although this patent documentation can help people to be quickly found out destination, but it still be unable to do without network.

Utility model content

For the weak point that prior art exists, the utility model proposes a kind of device recovering starting point, this device is without online, merely with the acceleration transducer of gyroscope, press recording key when setting out and calculate the route shape set out, press the key that shows the way when going back, by calculating, pointer may indicate that you need the direction advanced, thus the road passed by before finding you, it is ensured that you can walk back starting point. Without network, not by Electromagnetic Interference. Homeposition is found with form the most simply and easily, outdoor indispensable.

This utility model adopts the following technical scheme that

A kind of device recovering starting point, it includes base and the pointer being arranged on base, gyroscope it is provided with in base, acceleration transducer, A/D modular converter, memory module, control module and servomotor, gyroscope, acceleration transducer is connected with A/D modular converter respectively, A/D modular converter, memory module is connected with control module respectively with servomotor, gyroscope, acceleration transducer acquisition angle speed and linear velocity, and change to controlling module via A/D modular converter, control module and control servomotor, corresponding angle is pointed to by driven by servomotor indicators turn.

Further, base being additionally provided with display, display is connected with controlling module.

Further, in base, it is additionally provided with wireless communication module, controls module and set up communication connection by wireless communication module with mobile equipment.

Further, wireless communication module is bluetooth module, WIFI module, 3G module or 4G module.

Further, controlling module is single chip machine controlling circuit or arm processor control circuit.

This utility model is distinctive in that relative to prior art: existing apparatus only has single direction giving system, and need networking, and the mode shown the way is very not direct, very inconvenient, and this utility model recovers this one side of starting point, can accomplish not network, be shown by the most direct pointer and inform route, safe ready. And need the device of networking can not use in the place being not recorded in high in the clouds without network or map, and this device can help people will not get lost in unknown place.

Accompanying drawing explanation

Fig. 1 is the structure chart of the device recovering starting point;

Fig. 2 is the schematic diagram of the device recovering starting point.

Detailed description of the invention

For further illustrating each embodiment, this utility model is provided with accompanying drawing. These accompanying drawings are a part for this utility model disclosure, and it is mainly in order to illustrate embodiment, and the associated description of description can be coordinated to explain the operation principles of embodiment. Coordinating with reference to these contents, those of ordinary skill in the art will be understood that other possible embodiments and advantage of the present utility model. Assembly in figure is not necessarily to scale, and similar element numbers is conventionally used to indicate similar assembly.

In conjunction with the drawings and specific embodiments, this utility model is further illustrated.

Consult shown in Fig. 1 to Fig. 2, a kind of device recovering starting point of this utility model preferably embodiment, it includes base 4 and the pointer 2 being arranged on base 4, it is provided with gyroscope 41, acceleration transducer 42, A/D modular converter 43, memory module 45 in base 4, controls module 44 and servomotor 46, gyroscope 41, acceleration transducer 42 are connected with A/D modular converter 43 respectively, A/D modular converter 43, memory module 45 are connected with control module 44 respectively with servomotor 46, and servomotor 46 controls the rotation of pointer 2.

Gyroscope 41 is used for recording angular velocity, acceleration transducer 42 is for line speed record, the record information of gyroscope 41 and acceleration transducer 42 passes to control module 44 through A/D modular converter 43, A/D modular converter 43 converts electrical signals to digital signal, controls storage after module 44 receives these information and arrives memory module 45.

Controlling module 44 and send control instruction to servomotor 46, control the rotation of servomotor 46, servomotor 46 drives turning to and angle of three directions controlling pointer 2.

Shown in Fig. 1, base 4 is provided with show the way key 1 and recording key 3, and user is pressed recording key 3 and started to record the route that user is passed by, and presses the key 1 that shows the way and recovers starting point for user and show the way.

User presses recording key 3 when setting out, and all information that from homeposition, user is arrived at position are recorded. Wherein, including the speed in each moment, acceleration, angular velocity and angular acceleration. The route map that information synthesis user according to record is passed by.

Owing to the output signal of gyroscope 41 and acceleration transducer 42 is the signal of telecommunication, after this embodiment uses A/D modular converter 43 to convert electrical signals to digital signal, it is transferred to control module 44, controls module 44 and these information are stored in memory module 45.After arriving at the destination, user presses recording key 3 again, so far, records work and completes, and this embodiment has write down one section of unfamiliar distance of user, in case user is got lost.

When user wants to return to starting point from destination, press, in destination, the key 1 that shows the way, according to stored information, control module 44 and send control instruction to servomotor 46, drive turning to and angle of three directions controlling pointer 2. While user moves according to pointer 2, this embodiment according to workflow management before go out user position and lower a moment this direction to walk, indicate again by pointer 2. Namely user may return to start position according to the direction of not pointer 2 indication in the same time.

Additionally, also can be provided with display on base 4, display is connected with controlling module 44. It is additionally provided with wireless communication module in base 4, controls module 44 and set up communication connection by wireless communication module with mobile equipment. The route passed by by user is transferred on mobile equipment. Wherein, wireless communication module is bluetooth module, WIFI module, 3G module or 4G module. Controlling module 44 is single chip machine controlling circuit or arm processor control circuit.

Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; this utility model can be made a variety of changes in the form and details, be protection domain of the present utility model.
