Description

Portable precision watch with additional function

The present invention relates to a kind of portable precision watch with additional function that meets claim 1 preorder, this table is very small and exquisite, can carry at any time with this, particularly is used as pocket-watch and wrist-watch, and is extremely easy to use.This small and exquisite pocket-watch and wrist-watch are known to have various function: stopwatch function such as stopwatch, alarm clock, zebra time are shown; Its additional function such as counter, data storage, even also have temperature and weather Presentation Function.

On the other hand, for example as radio broadcasting stopwatch or satellite stopwatch and for example as the chronograph watch of traveling clock, be in the public eye, but need the very big thing of expense just can try to achieve precise time, only be only in certain limited zone can usefulness for these stopwatchs in other words for this reason.

In addition, from a diverse aspect, navigational system is that people are familiar with, for example as marine installation, and recently also as the guide piece on the automobile, and the Autotravel that produces of Bosch company for example.Said apparatus is sizable really, it is very bothersome to use, and very expensive, and they are made up of the part that several are separated, and at this, orientating function mainly is to store card and expensive to decide journey software.This situation needs big storage and rated output, and corresponding high energy consumption.In addition, known also have portable GPS (GPS) orienting device, and these devices can only be realized more or less bothersome guide function.

But, utilize the small and exquisite portable chronograph watch as pocket-watch, especially as wrist-watch, remain and realize important orientating function till the ass ascends the ladder.

Therefore, task of the present invention provides a kind of very small and exquisite can using and portable chronograph watch everywhere, this table can also be realized orientation everywhere in not familiar area by way of parenthesis, and can point out the direction towards the destination of being hoped for from any position of not knowing.Refer more particularly to wrist-watch and pocket-watch, such table can carry at any time, for example is placed in the coat pocket or is placed in the woman style handbag.In addition, it is relatively cheap that above-mentioned this precise orientation stopwatch is compared with large-scale orienting device, and energy consumption also is minimum.

Above-mentioned task is solved to meet chronograph watch described in the claim 1.The table that provides a kind of small and exquisite individual to use whereby first, this table are except having accurate accurate clocking capability, and any in the world area can both carry out orientation at desired destination, can also carry at any time.

The possibility of the directed or general satellite orientation of GPS (GPS) usually will be under by the condition of a map or a map of the city actual utilization the in addition.Geographic longitude and latitude data must be arranged on the map.Must be earlier the geographic position of the site of trying to achieve from GPS (GPS) receiver be transferred on the map, people could carry out orientation around it then.As long as the destination also is documented on the map, at this moment also can draw each orientation and towards the direction of destination.Put well as if this map is exposed to the north, can obtain the direction indication of " simulation ".The map that is used for particular locality also can be at this moment electron storage in addition, and the position of measuring originally can automatically be inserted.

At this moment the disadvantage of Chan Shenging is, the orientation on the area promptly can not be answered with GPS (GPS) direction method following of the condition that does not have map reference point by problem most important and the most frequent in the orientation of destination direction.The of course not frequent presumable thing of this point, nonsensical in other words conj.or perhaps: do not have map when on hand, perhaps do not indicate longitude and latitude on the map, the area does not have drawn, that do not have in this area in other words that feature is indicated a little or can not be recognized and can not differentiate, just as in field, in the forest, in the desert, on high sea or this kind situation arranged in the dark.

GPS (GPS) is measured combination with the compass parameter can realize direction calculating and indication from any position to any destination on orienting device, as long as just know that the coordinate of destination can.Above-mentioned task can utilize guider for example to solve on boats and ships.Of course not anyone can both handle this device, and also carry at any time anything but certainly.

The chronograph watch that utilizes the present invention to propose, in the time of not only can realizing the survey of absolute precision, and operation is very simple, all can directly carry out orientation to anyone, at this, the indicating device of a pointer shape is irrelevant with the turned position of the stopwatch that keeps level, and a similar pointer compass that refers to north points to desirable destination.

Some superior especially embodiment are: wrist-watch, pointer, antenna, operating element and two kinds of various combinations that function is accurate timing and accurate pointing parameter; " pocket-watch, promptly small and exquisite clock and watch comprising pocket-watch, traveling clock and the similar stopwatch that is worn on the neck, all can carry whenever and wherever possible easily in addition.

Every claim of subordinate relates to favourable improvement more of the present invention, has proposed exquisite especially, light and energy-conservation embodiment and component structure, thereby has made that purposes is more extensive, orientating function is more.Below will the present invention will be further described according to some embodiment and accompanying drawing.Accompanying drawing is:

Fig. 1 schematically shows the chronograph watch 1 that bright the present invention proposes, and the combination of this table is as follows: the watch time functor 11 that has timing quartz 17; A satellite navigation formula receiver is here as GPS (GPS) receiver 3 of being with antenna 4; With a compass 6 that has magnetic field sensing element 16, in order to determine that south, magnetic north is to Nm; Also have a computing electronics 5.

Input element

7 and 7b are used for importing the coordinate of Z, Z1, Z2 of can selecting your destination.These destinations can be stored in the storer 9, and can change, for example in an EEPROM-storer.Utilize computing electronics 5 to determine the coordinate of position S, S1, S2, and from the coordinate of the coordinate of position S and target ground Z, calculate towards the direction SZ (referring to Fig. 3,4) on target ground.Utilize compass to determine the location of this stopwatch, just determine the axis and the angle W of geographic north between N of table, at this, geographical north orientation N is determined (utilize stored drift angle value) by proofreading and correct according to the magnetic drift angle of the position of being tried to achieve by measured magnetic north orientation Nm.Then, under the situation of the orientation of stopwatch, in an

indicator elment

8 or 8b, the direction of head for target ground Z, Z1, Z2 is shown in consideration, that is to say as vector indication V, irrelevant with turning to of stopwatch, vector indication V points to target ground Z according to direction SZ all the time.On the executive component 7 and represent the time function of stopwatch with 7a, 8a on indicator elment 8, with 7b, 8b represents orientating function.All elements combination with this chronograph watch of orientating function become compact functional unit, and operation of data is carried out in a microprocessor 10.The stopwatch time t that is provided by stopwatch quartz piece 17 is constantly controlled or is proofreaied and correct by GPS (GPS) the time tg of accurate reception, like this, just indicates the time t of pinpoint accuracy on stopwatch time indication 7a.An energy supply assembly 2 of stopwatch has very high energy density, the energy storage device that can recharge preferably, lithium-ions battery particularly, perhaps Ni-metal hydride accumulator, their can be linked on the equipped small charger 49 through web member 12.Some additional web members also can be used for for example an exterior antenna 14 or a programmed control PC50 (Figure 10).

The all functions of stopwatch, be GPS (GPS) function, compass function, stopwatch time function and calculation function, preferably highly integrally be combined in the electronic computing units 5, for example some kinds of functions be integrated in the single chip 15.Fig. 2 shows clear this point, here, except GPS (GPS) antenna 4 and magnetic field sensing element 16 and stopwatch quartz element 17, every other signal Processing processing and calculation function mostly make up in the chip 15, are combined in other words in the microprocessor 10 of electronic computing units 5.

Fig. 3 shows bright, utilizes vector pointer V to try to achieve and point out towards the direction of desirable target ground Z.At first utilize GPS (GPS) to determine location coordinates, calculate simultaneously and become the geographic direction SZ of angle WZ with north orientation N, and stored towards target ground Z at position S place.Then, utilize compass according to geographic north to the location at that time of determining stopwatch, that is to say, calculate position and angle W1 between stopwatch axis U1 and north orientation N and the angle WW1=WZ-W1 of stopwatch axis U1, and utilize vector pointer V in indication 8, correspondingly to indicate direction SZ.If this moment, stopwatch rotated, for example turn to position U2, just can automatically be compensated in the time certain (for example also can select) so, so vector pointer V points to all the time towards the same direction of target ground Z this.In addition, determine angle W2, and the vector that is among the WW2=WZ-W2 of angle is shown in indication at position U2.Utilize that these record with GPS (GPS) position coordinates that stores, can also obtain other desirable target directions very soon, and indicate, locate and carry out GPS (GPS) once more.

Said circumstances also can be as can be seen from Figure 4.This illustrates the sequential of bright different each function.Stopwatch time function (11) must run through overall process.The most expensive function is determine (3) of GPS (GPS) coordinate, is only just connected when the new location of needs.How long the calculating of Duan lining (6) and target direction SZ relatively and indication also just need how long just to connect (7,8).V1 is here corresponding to position S1 in the vector indication, and V2 is corresponding to position S2 in the vector indication.

Fig. 5 a-d shows that bright other vector shows and directed the demonstration and the stopwatch time function, here access by the catalogue control mode, and on same indicator elment 8, promptly be revealed as time indication 8a again as direction indication 8b, for example utilize LCD (LCD) to reach this purpose.

Fig. 5 a shows the vector indication V on Ming Dynasty target ground, has distance parameter D and direction parameter SZ.

Fig. 5 b shows bright stopwatch time function, have quasi-mode intend the stopwatch pointer and digit time parameter.

Fig. 5 c shows the bright a kind of indication that can select desirable direction, here is G=42 ° in the Pyxis.

Fig. 5 d shows the orientation of a bright target direction V parallel with stopwatch axis U that tried to achieve.Utilize a directed edge U of stopwatch also can carry out orientation.(target ground orientation, and utilize button fixed orientation angle)

Basic purpose of the present invention is:

-each combination of elements: stopwatch, the calculating of GPS (GPS) and the chronometer time derivation that matches with it, compass and target direction thus and with the direct vector indication of analog form;

-left out unnecessary degree of accuracy and function;

The microminiaturization of-each assembly;

-with a plurality of function combinations with collect among the electronic circuit;

Working method and least energy consumption that-acquisition is best.

Only in this way can realize with these functions collect in the small-sized stopwatch that can carry at any time particularly its weight for example less than 100 the gram pocket-watches or wrist-watch on.Each embodiment shows the compactly designed especially various possibility of realization chronograph watch, and this stopwatch also comprises big relatively indicating with apparent vector.Known the sort of quite large-scale portable orientor can not be carried on the contrary at any time.

Fig. 6 a, b show bright its size for example be approximately 5 * 5 * 2cm (centimetre) two front elevations of top and side of pocket-watch 20.GPS (GPS) antenna 4 should have one at this and be hemispheric antenna pattern substantially, and this point for example can be utilized helical aerials shown in Figure 6 or utilize Fig. 7 and the pancake antenna of maintenance level shown in 8 is realized.Owing to do not need pinpoint accuracy here usually, so antenna also can design correspondingly smaller and more exquisitely and simpler, the satellite that for example requires institute to comprise compared with higher accuracy can lack for this reason, and a common two-dimensional coordinate locate (X, Y) also just enough.Fig. 6 a shows a bright helical aerials 4 that is in folded position, and chronograph watch can transport simply in this state.Among Fig. 6 b, antenna has been pulled out and has been in accepting state (42).The deployment scenarios that exemplarily shows accumulator 2, compass 6, electronics computing element 5, indicator elment 8 and executive component 7 here.

Example shown in Figure 7 shows another kind of compact pocket-watch 20, and it has an antenna 4 that is designed to amount to the flat configuration of lid 25.Therefore, when being in folded position here, say that in principle the double plane of stopwatch can be used for operation: the left side is an antenna surface 4, and the right is index plane and

input face

8,7.

Fig. 8 shows the wrist-watch 30 that bright the present invention proposes, and a tours antenna 4 is arranged on stopwatch glass face 32, also has a flat liquid crystal display (LCD) device 8 and a compass 6 in the bottom.Input element 7 here is to be made of technical known button of stopwatch and turn-button.Replace a kind of digital lcd display (LCD), also can design a kind of direction indicator elment with vector V, with as simulated pointer 19.In order to utilize space condition very narrow in the wrist-watch better, can or entirely be integrated in the watchband 31 antenna part ground.

Fig. 9 a, b show a bright example that highly utilizes the space especially.On this wrist-watch 30, wrist-watch can not amount to ground (41) be fixed on the watchband 31, according to this, normal close to close for example utilize kayser to be fixed in the state, be placed in according to Fig. 9 b on the last plane of pointer of stopwatch time function 8a.In being in the open mode shown in Fig. 9 a, the directed pointer 8b that has executive component 7b is positioned on the flat horizontal surface of visible face-off mutually, and meanwhile, antenna 4 links to each other with stopwatch through rotary gemel, and is integrated in the watchband 31." two-sided " structure, the limited surface that the is rather narrow utilization factor in principle of wrist-watch can reach three times: be used for GPS (GPS) antenna, be used for time function, and be used for orientating function by this.

Figure 13 shows that another bright example is that a kind of " two-sided " it can be along towards vertically the amounting to of watchband 31 (41) for wrist-watch 30, different shown in this wrist-watch and Fig. 9 a, the b.When being fixed on normal position 8a, demonstrate the stopwatch time function at its visible upper side, when the open mode 8b that is in shown in the figure, just can see the downside that has directed indication.Here, also antenna 4 can be integrated in the watchband 31.

Figure 10 shows the brighter additional function that might link to each other with chronograph watch.Therefore, for example connect an additional antenna 14, with substitute integrated antenna 4, antenna can be placed in automobile for example on the car or settle on aboard ship the vantage point here, and is fixed.The possibility of also showing an outside counter 50 of bright connection among the figure, with as the change scheme.Therefore, for example can design and import the revolution plan, perhaps can utilize chronograph watch evaluation (also can referring to Fig. 1) in addition after the geographic factor received is on programmable counter.

Figure 11 shows a bright exemplary applications, show in outing, for example walking is roamed or is gone on a pleasure trip on one's bike, after arriving route 61 by bus, the chronograph watch that has orientating function that how to use the present invention to propose, at this moment certain place on the way by the button automatic reception, is also stored in the hope of target ground Z11, Z12, Z13.At the target ground Z13 automobile that stops, simultaneously this place is determined as major heading ground Z0 and marked.If there is certain to wish, also can for example Z15 and Z16 import by way of parenthesis by the geographic coordinate of importing them with other target ground.In roaming,, also its geographic coordinate is fixed as target ground at target ground Z14 along route 62.In the stroke afterwards respectively at different place 63 by the desirable orientation of carrying out.At this moment, not only can obtain towards the direction of major heading ground Z0 with from the distance D 0 on major heading ground, also may obtain towards direction and the distance of other impact point Z,, and can also find automobile more very naturally at parking site Z0 so that can obtain an omnibearing location drawing thus.

Just for temporary transient definite those transient target ground Z0 of certain for example outing of time institute, Z11 to Z16, perhaps on some festivals or holidays or the false all determined targets of joint ground, every be of practical significance, they can be stored in the storer 9, also can be with they cancellations once more, and replace the new target ground that realistic meaning is arranged.

In addition, can also take in nonvolatil target ground, they have the validity of long period, the institute of for example having a rest the villa of oneself, weekend or vacation, perhaps Dui Waikaifang the hostel that people's dealing is constantly arranged.

Figure 12 represents, the major part of whole stopwatch surface F preferentially is used to have the index plane FA of the vector indication V of indicator elment 8, like this, even under the wrist-watch of narrow and small restriction or pocket-watch size condition, also can be clear that very much directed indication.Index plane FA accounts for more than 50% of F of stopwatch surface, preferably for example accounts for 70-80% or more.With regard to the linear dimension of stopwatch diameter L in other words, the diameter LA of indication will reach the former 70% at least, preferably reaches 80-90%, perhaps even more.This large-area design structure of index plane FA also shows bright at Fig. 5 a.

Those target ground with a kind of permanent universal significance also can be taken in, for example concerning the Moslem as Meccah on target ground, this is to pray because it is essential can past forever Meccah pay respects to for Moslem religionist.The chronograph watch that utilizes the present invention to propose.First can be directly indicate towards the direction in Meccah, target ground by the arrow on the button at any time in the whole world, for this reason, only need with this target the program of enrolling get final product.

In addition, also often occur such sight in daily life: people are very glad and had fortunately just pointed out originally toward the direction on an inevitable target ground, for example can turn back to the meeting point in fair or the exhibition, perhaps can pick up on the parking lot automobile of oneself in strange city and area, perhaps pick up the hotel lived at dark.For this reason, direction indication V also can be designed to illuminate.This not only is related to the people of the ability of taking one's bearings, and might as well consider often lost children, and the target direction indication that they utilize the present invention to propose helps to pick up correct homeward journey.
