Embodiment
The embodiment of the invention discloses a kind of barrier dangerous situation reminding method and a kind of handheld terminal, the information of the various barriers by Real-time Obtaining handheld terminal periphery, and by calculating the relative distance of estimating that can calculate in advance next moment barrier and this handheld terminal, thereby estimate relative distance according to this, holder to handheld terminal carries out early warning, can learn in advance the various barrier dangerous situations of periphery, and make a response in time, to avoid the generation of various danger or accident.
Below in conjunction with accompanying drawing, the embodiment of the present invention is described further, it should be noted that, in this specification, each embodiment adopts the mode of going forward one by one to describe, what each embodiment stressed is and the difference of other embodiment, between each embodiment identical similar part mutually referring to.For the disclosed device of embodiment, because it corresponds to the method disclosed in Example, so description is fairly simple, relevant part illustrates referring to method part.
Embodiment mono-
As shown in Figure 1, the method is applied to a handheld terminal to the flow chart of the disclosed barrier dangerous situation of embodiment of the present invention reminding method, concrete, and the method comprises the following steps:
Step S101: the obstacle information of Real-time Obtaining handheld terminal periphery, described obstacle information at least comprises the actual relative distance of barrier and this handheld terminal;
It should be noted that, the mode of obtaining handheld terminal periphery obstacle information has multiple, can adopt various distance measuring sensors, camera or radar detection apparatus etc., in the present embodiment, only describe as an example of the obstacle information of handheld terminal periphery described in radar detection apparatus real-time detection example, in the present embodiment, be preferably the radar detection apparatus of infrared or bluetooth, described radar detection apparatus can be external or be embedded on described handheld terminal.
Wherein, self neighboring area that the included scope of described handheld terminal periphery can observe for this handheld terminal holder eyesight, concrete, if described handheld terminal has a display screen, the included scope of described handheld terminal periphery is preferably, with a sector region of the displaying contents opposite direction of described handheld terminal display screen.Described displaying contents direction is for being parallel to described display screen place plane, and the direction identical with the direction of displaying contents (word or image etc.), under normal circumstances, namely being parallel in the plane at described display screen place, the direction at reader place.
As shown in Figure 2, the direction of the displaying contents (word or image etc.) of handheld terminal 1 is A direction, so, the barrier of this handheld terminal 1 periphery that can detect is positioned at B direction, and is mainly positioned at the sector region 2 of B direction, that is to say, this handheld terminal holder is positioned at the position of A direction, and in the time that this handheld terminal holder bows reading, what the most easily ignore is the barrier that is positioned at B direction, therefore need the obstacle information of this direction of Real-time Obtaining.
Certainly, in order to obtain the obstacle information of described handheld terminal periphery wider scope, as be positioned at the people of handheld terminal holder body side or the information of thing, the scope of described handheld terminal periphery can also extend to handheld terminal holder's the left and right sides, i.e. the sector region 3 of C direction and the sector region 4 of D direction in Fig. 2.
In order to obtain the obstacle information of handheld terminal periphery, for different handheld terminals, the position that described radar detection apparatus is installed may be different, and the size of described sector region scope depends on the size of angle α and the detection range of sniffer, the two depends on again selection and the installation site of described sniffer, in the case of select sniffer identical, the size of described sector region just depends primarily on the size of angle α.In theory, when radar detection apparatus is embedded in to the side of handheld terminal, the scope of the sector region detecting is less than the scope of the sector region detecting when radar detection apparatus is placed on to the side of handheld terminal, and being often inferior to the former in the latter's shape design outside, concrete How to choose is determined according to actual conditions.
Below for different handheld terminals, to radar detection apparatus is different, quantity is installed, and while being positioned at different installation site, the scope detecting is illustrated respectively.
As common key-press formula mobile phone, when 1 radar detection apparatus is only installed, described radar detection apparatus can be arranged on the side perpendicular to mobile phone display screen, it is mainly the just side edge to front of mobile phone, when holder is gripped, this radar detection apparatus can detect a sector region in holder dead ahead, i.e. sector region 2 in Fig. 2; Certainly, try one's best extensively for the region of surveying, can also increase the quantity of radar detection apparatus, as being respectively provided to a few sniffer at two sides adjacent with the side in dead ahead, the scope that now, can detect comprises the sector region 2,3,4 in Fig. 2; If only use 2 radar detection apparatus, these two radar detection apparatus can be arranged on respectively to two intersection point places of two sides that mobile phone is just being adjacent the side in front, as shown in Figure 3, now, when holder grips, the scope that this mobile phone can detect comprises sector region 5 and sector region 6, and, can be the form that can swing by the probe designs of two radar detection apparatus, thereby can regulate very easily the scope of sector region 5 and sector region 6, to adapt to the detection demand under varying environment, as shown in dotted lines different in Fig. 3.
As the handheld terminal of pad class or can change with the rotation of display screen the mobile phone of displaying contents direction, described display screen rotate to be rotation clockwise or counterclockwise in the plane parallel with display screen, now the direction of word or image also can be rotated along with the rotation of display screen, and direction of rotation is identical.
For this class handheld terminal, described radar detection apparatus can be arranged on the side edge that is likely positioned at holder dead ahead, that is to say, the displaying contents direction of handheld terminal can be using any one direction in the corresponding four direction of self side as to(for) pad class, this handheld terminal all can arrange described radar detection apparatus perpendicular to four sides of display screen, in the time that wherein certain direction is as displaying contents direction, radar detection apparatus corresponding thereto will be opened, survey the sector region with this displaying contents opposite direction, while being displaying contents direction as the A direction in Fig. 4, the B direction corresponding with it, the radar detection apparatus that is b side will be opened, survey corresponding sector region, certainly, for investigative range wider, also can open two other radar detection apparatus of non-display content direction, be two radar detection apparatus of c side and d side.
That is to say, for the handheld terminal of displaying contents direction-agile, as long as and the sector region of displaying contents opposite direction all can be used as the investigative range of radar detection apparatus, the corresponding side edge vertical with display screen all can be installed radar detection apparatus, and, the variation of displaying contents direction is depended in the open and close of the radar detection apparatus of which direction, and in a word, the detection direction radar detection apparatus identical with displaying contents direction is all the time in closed condition.Certainly, also described radar detection apparatus can be arranged on to four intersection point places of four sides, and probe direction can swing, to meet the demand of different detection event.
Such as, the holder of this handheld terminal on the way moves slowly, dangerous may be from his dead ahead, or side, wherein the danger in dead ahead is higher, now just at least can open the radar detection apparatus of detection direction and displaying contents opposite direction; If the holder of this handheld terminal is taking transit bus, dangerous most probable is from his side, the i.e. direction relative with bus wall, now at least can open the radar detection apparatus of a perpendicular side of detection direction and displaying contents direction, if radar detection apparatus is arranged at side intersection, can rotate the direction of probe, make its emphasis survey the larger direction in dangerous source.
It should be noted that, above is only to describe as an example of the terminal of different mobile phones and pad class example, and the thought of the embodiment of the present invention can be applied to any need to carrying out in the terminal of barrier dangerous situation early warning, and this terminal does not have display screen and is fine yet.And the selection of above-mentioned sniffer and mounting means also can not be served as the restriction to embodiment of the present invention thought.
Step S102: utilize Preset Time interval and in the initial time at described Preset Time interval and the difference of described actual relative distance between the finish time at described Preset Time interval, calculate the relative average speed of barrier and this handheld terminal described in current time;
Step S103: according to the relative average speed of current time and Preset Time interval, calculate the relative distance of estimating of barrier and this handheld terminal described in next moment;
Step S104: according to the relative distance of estimating of barrier described in described next moment and this handheld terminal, carry out early warning.
The method of described early warning can be for voice message, buzzing prompting, dodge screen prompting, at least one in the demonstration screen display obstacle information of handheld terminal, demonstration screen display dynamic effect at handheld terminal, concrete alarm method is described in detail in the following embodiments, repeats no more here.
It will be appreciated by those skilled in the art that, the barrier type of handheld terminal periphery is mainly divided into two classes, static-obstacle thing and dynamic barrier, the state of handheld terminal is also divided into inactive state and motion state, but owing in the present embodiment being relative average speed by calculating the two relative distance of carrying out next moment of budget, no matter therefore the state of this handheld terminal and periphery barrier thereof how, all can carry out the danger of disturbance in judgement thing to this handheld terminal holder by estimating the two relative distance of next moment, it is the probability that described barrier contacts with this handheld terminal holder.
It should be noted that, barrier depends on the relative motion state of the two to the danger of hand-held holder terminal, alarm mode in the embodiment of the present invention, on the basis of estimating relative distance according to next moment, can also be determined according to the relative motion state of the two.
For instance, if the two is in relative motion state, and, the movement velocity of barrier is faster, and the relative average speed of the two is just larger, and barrier is just large to the danger of hand-held holder terminal, next moment the two to estimate relative distance just nearer, therefore according to this estimate relative distance can the danger of simple disturbance in judgement thing to hand-held holder terminal, thereby carry out corresponding early warning, to point out handheld terminal holder to note periphery barrier situation; If the two is in relative static conditions, the relative average speed of the two is zero, and current time is identical with the relative distance in next moment, gets final product disturbance in judgement thing very low to the danger of hand-held holder terminal, can not carry out early warning.
The disclosed barrier dangerous situation of embodiment of the present invention reminding method, the information of the various barriers by Real-time Obtaining handheld terminal periphery, and by calculating the relative distance of estimating that can calculate in advance next moment barrier and this handheld terminal, thereby estimate relative distance according to this, holder to handheld terminal carries out early warning, the threat situation of the various barriers that can learn in advance periphery to himself safety, and can make in time reply, to avoid the generation of various danger or accident.
Embodiment bis-
The flow chart of the disclosed barrier dangerous situation of the present embodiment reminding method as shown in Figure 5, what the method in the present embodiment was different from a upper embodiment is, the mode of described barrier dangerous situation being carried out to early warning is specialized, as step S204: according to the grade of relative distance and the corresponding relation of type of alarm between barrier as described in setting in advance and this handheld terminal, adopt the type of alarm corresponding with the grade of estimating relative distance in next moment, described barrier dangerous situation is carried out to early warning.
The corresponding relation of described relative distance grade and type of alarm specifically can be understood as, in the time that described barrier is different from relative distance between this handheld terminal, type of alarm is also different, general described relative distance is nearer, type of alarm is also strong with regard to Shaoxing opera, as increasing in alarm sound, the rhythm of buzzing is more and more faster, and the frequency of dodging screen is more and more faster etc.
Below in conjunction with Fig. 6 and Fig. 7, the alarm mode in the present embodiment is described, Fig. 6 is time shaft, and Fig. 7 is the schematic diagram that is related to of handheld terminal search coverage and barrier.As shown in Figure 7, can be according to the relative distance of handheld terminal and barrier, on detection direction, the sector region that the radar detection apparatus of handheld terminal can be detected is divided between several distance regions, it is the grade of relative distance, range difference between between every two distance regions can be identical, also can be different, from handheld terminal more close to, range difference is less, represent barrier from handheld terminal more close to, the growth of degree of danger is faster, is only all mutually example with range difference here and describes.
If the straight line detection range of radar detection apparatus is L, this detection range is divided into 4 intervals, distance between between every two distance regions is L/4, often differ L/4 as a relative distance grade, described relative distance grade be divided into 0～L/4, L/4～L/2, L/2～3L/4,3L/4～L, Preset Time is spaced apart t.Moment of detection range that a certain barrier is entered into radar detection apparatus is as zero moment, now the actual relative distance of this barrier and handheld terminal is L, by the time after the t moment, the actual relative distance that radar detection apparatus detection obtains this barrier and handheld terminal is D1, in the t of Preset Time interval, the poor S1=L-D1 of actual relative distance of this barrier and handheld terminal, the relative distance that is the two has reduced S1, in the t time, relative average speed V1=S1/t=(the L-D1)/t of the two, according to this relative average speed V1, and Preset Time interval t, can extrapolate, in the 2t moment, this barrier and handheld terminal estimate relative distance D1 '=D1-V1*t=D1-(L-D1)=2D1-L, obtain estimating after relative distance D1 ' of 2t moment, judge which distance regions D1 ' is positioned between, it is relative distance grade, adopt with this distance regions between corresponding type of alarm carry out early warning, by that analogy, while arriving 2t moment, can estimate according to the relative average speed in t～2t time the relative distance of estimating in 3t moment, and adopt corresponding mode to carry out early warning.
In addition, in the disclosed method of the present embodiment, can also comprise, when every, during through a Preset Time interval, which distance regions judgement now this barrier is positioned between with the actual relative distance of handheld terminal, and between employing timely and this distance regions, corresponding type of alarm carries out alarm.That is to say, after carrying out alarm according to the actual relative distance of current time, then according to the average relative of current time, calculate in advance estimating relative distance and carrying out early warning of next moment.
It should be noted that, under many circumstances, barrier is not just to this handheld terminal, be that the position of barrier or the direction of motion and handheld terminal holder's the direction of motion have certain angle, only and relative average speed poor according to actual range judges and may have certain error in this case, therefore in practical operation, can be by relative distance and average relative etc. between barrier and handheld terminal, be parallel to handheld terminal direct of travel and carrying out projection perpendicular to described handheld terminal direct of travel respectively, according to the component that is parallel and perpendicular to described handheld terminal direct of travel, judge, in fact, the final component according to the actual relative distance at the described handheld terminal direct of travel of being parallel and perpendicular to of current time is reported to the police, and carry out early warning according to the component of estimating relative distance that next moment of estimating is parallel and perpendicular to described handheld terminal direct of travel.
Accordingly, described relative distance grade can also be subdivided into the relative distance grade that is parallel and perpendicular to described handheld terminal direct of travel, as shown in Figure 8, the search coverage that is parallel and perpendicular to described handheld terminal direct of travel is carried out to parallel with vertical intersection divides, dividing mode is expressed as in detection plane, can adopt the lines that are parallel and perpendicular to described handheld terminal direct of travel to intersect division, also can adopt the lines of other directions to divide, in the different intersection regions of relative distance, corresponding type of alarm is also different.
It should be noted that, as shown in Figure 7, in the time that described handheld terminal periphery has multiple barrier, with estimating in relative distance of multiple barriers described in next moment calculating and this handheld terminal, the nearest corresponding type of alarm of relative distance of estimating carries out early warning.That is to say, in the time that handheld terminal holder periphery has the barrier of multiple potential hazards, the relative distance of estimating with the most dangerous barrier is carried out early warning, now holder will notice the barrier that other are dangerous simultaneously, so that holder can farthest avoid the generation of dangerous situation at any time.
In addition, taking relative distance in basis for estimation, can also increase other basis for estimation, as the direction of relative movement of barrier and handheld terminal, first need to determine the direction of motion of described barrier, the direction of motion of barrier can be determined by the position of the barrier before and after each Preset Time interval, if the direction of motion of the direction of motion of barrier and handheld terminal is not occured simultaneously, this barrier is just lower to the danger of hand-held holder terminal, as the barrier d in Fig. 7.
Judgment mode in the present embodiment still judges as main taking relative distance, the selection of the bases for estimation such as direction of relative movement, can determine according to actual conditions, certainly can also comprehensively judge in conjunction with the factor such as relative distance and direction of relative movement, relative velocity, judgment mode is similar, is not described in detail here.
