Embodiment

For becoming apparent the purpose of this utility model, technical characteristic and advantage, below lift preferred embodiment and coordinate accompanying drawing to be described in detail.

Please first consult Fig. 1 and Fig. 2, for supervising device 10 of the present utility model is in the schematic perspective view of different visual angles.As shown in the figure, supervising device 10 comprises a body 11, this body 11 is formed with an opening 12, extends along first direction X.Supervising device 10 also comprises a plurality of transmitter and receiver is arranged at this body 11 inside; Specifically, described transmitter is sequentially arranged in this opening 12, and described receiver is arranged in this opening 12 equally according to corresponding described transmitter.Thus, described transmitter outwards can send ripple by driving ground from this opening 12, described ripple can be the ripple with directive property, such as infrared light-wave or ultrasonic, and transmits along the second direction Y (as shown in Figure 3) vertical with this first direction X in fact, described receiver then via this opening 12 accept respectively this relative transmitter send and ripple through reflecting.

The utility model supervising device 10 comprises M transmitter and N number of receiver, and wherein M and N is positive integer, M≤3 and usually M equal N, but its quantity be not restricted also do not need equal, as long as can the purpose of this utility model be reached.

Refer to Fig. 3, be depicted as a preferred embodiment of the present utility model.As shown in the figure, the present embodiment is described with 7 transmitters 21a, 22a, 23a, 24a, 25a, 26a, 27a and 7 corresponding receiver 21b, 22b, 23b, 24b, 25b, 26b, 27b, and described transmitter 21a ~ 27a sends described ripple 31,32,33,34,35,36,37 respectively, received for receiver 21b ~ 27b after reflection, and for convenience of description, in accompanying drawing, same group of transmitter and receiver are indicated in same position, in fact can separate and be disposed adjacent.Wherein, described ripple 31 ~ 37 is infrared waves, have directive property and transmit along second direction Y, and the proper definable of the bang path of described ripple 31 ~ 37 goes out a monitoring range.

For example, supervising device 10 of the present utility model can be arranged on above the head end of a sick bed, supervising device 10 is installed in above sick bed 90 one end, it has certain altitude, make described monitoring range haply when patient lies down above, its width is equal with sick bed width haply, and length is to be no more than bed length for principle; That is in monitoring range, but when sitting up on one's sick bed, then monitoring range can not be entered when patient lies down.Supervising device 10 can be assemblied on wall, or is installed on bedstead, all can implement.

Please consult Fig. 5 further, when the first subject matter 50 (being such as patient) is positioned within this monitoring range, described ripple 31 ~ 37 part that described transmitter 21a ~ 27a sends can be reflected by the first subject matter 50, and received by this receiver 21b ~ 27b of correspondence, this supervising device 10 can judge the first position of subject matter 50 in this monitoring range accordingly.As shown in Figure 5, the ripple 33,34,35 only having transmitter 23a, 24a, 25a to send can be reflected by the first subject matter 50, then received device 23b, 24b, 25b receive respectively, other receivers 21b, 22b, 26b, 27b then can not receive the ripple 31,32,36,37 reflected by the first subject matter 50, therefore supervising device 10 and then can judge the position of the first subject matter 50, with Fig. 5, be positioned at the middle position of monitoring range exactly at corresponding transmitter 23a, 24a, 25a.

Please consult Fig. 6 further, it is original in the position of Fig. 5 that dotted line is depicted as the first subject matter 50, when the first subject matter 50 moves to the solid line position of Fig. 6, the ripple 32,33,34 that transmitter 22a, 23a, 24a send is projected to the first subject matter 50 and after reflection, received device 22b, 23b, 24b receive, now other receivers 21b, 25b, 26b, 27b then can not receive the ripple 31,35,36,37 reflected by the first subject matter 50, and then can judge the position of the first subject matter 50.

Please then consult Fig. 7, be depicted as the first subject matter 50 and continue from the position of Fig. 5 and Fig. 6 to move towards the edge of monitoring range.Now, the ripple 31,32 only having transmitter 21a, 22a to send is projected to the first subject matter 50 and received device 21b, 22b receive through reflection, and other receivers 23b, 24b, 25b, 26b, 27b then can not receive described ripple 33,34,35,36,37.Specifically, the moving process of the first subject matter 50 from Fig. 5 to Fig. 7, can sense by the receiver of reflection wave, be 3 receivers 23b, 24b, 25b from the beginning, to another 3 receivers 22b, 23b, 24b, be then only have 2 receivers 21b, 22b.Ground can be infered, if the first subject matter 50 maintains same mobile trend again, can only can sense by the ripple 31 reflected by remaining 1 receiver 21b, then next time point then can sense by the ripple reflected without any receiver again, means that the first subject matter 50 leaves monitoring range completely.

Described in brought forward, by receiving by the number change of the described receiver of the described ripple reflected, effectively can judge the mobile trend of this first subject matter 50 relative to this monitoring range, in other words, if receiving is successively decreased gradually by the number change of the receiver of the described ripple reflected (such as become 2 by 3, become 1 again, then become 0), this just can be defined and belong to patient by the behavior that sick bed leaves.

And if medical personnel's (or looking after the family members of patient) carry out as medical treatment or look after behavior, when patient is recumbency, by reflecting, received device 21b ~ 27b receives the ripple 31 ~ 37 that any transmitter 21a ~ 27a substantially can't be made to send, but medical personnel then can cause the reflection of ripple 31 ~ 37, and due to medical personnel be by entering outside monitoring range, therefore receive and be incremented to such as 3 by 0 exactly by the number change of the described receiver 21b ~ 27b of the described ripple 31 ~ 37 reflected.

When the group number of transmitter and receiver less as only having 3 groups time, its setting position then will adjust especially, directly can reflect the ripple that 3 transmitters send, just can have and successively decrease or increasing trend when patient is sat up.

More preferably, if in the moving process of the first subject matter 50, collocation receives by the combination of the described receiver 21b ~ 27b of the described ripple 31 ~ 37 reflected again, and the physical location of this first subject matter 50 in this monitoring range of namely arranging in pairs or groups, more can fine-resolution behavior kind.The receiver corporation such as receiving reflection wave is 21b, 22b, 23b, then can judge that the first subject matter 50 is in the side of bed, and if 23b, 24b, 25b, be then the centre at bed.And if combination changes with quantity simultaneously, be such as by 21b, 22b, 23b (3), become 21b, 22b (2), then become 21b (1), then become 0, just can judge be patient by left side from bed.

Remark additionally a bit in addition, above-mentioned number change, if by 0 directly become 3 non-ly increase progressively situation gradually, or the non-situation of successively decreasing gradually of 0 is directly become by 3, may be then that patient sits up on one's sick bed or lies down and causes, such behavior can further by confirming that the position of the first subject matter 50 is distinguished in the combination of receiver 21b ~ 27b, such as if receiver 23b, 24b, 25b these 3 receive described ripple 33,34,35, namely in the central authorities of monitoring range, namely can be considered the behavior that patient sits up on one's sick bed or lies down.

Preferably, described transmitter 21a ~ 27a system of the present embodiment is sequentially driven in turn, with the amount of saving energy, described ripple 31 ~ 37 is alternately transmitted in this monitoring range, and implement in aspect at this, corresponding receiver 21b ~ 27b is driven with transmitter 21a ~ 27a system in turn by synchronous and close, this supervising device 10 just can by receive described ripple 31 ~ 37 described receiver 21b ~ 27b number change and/or combination change, judge this first subject matter 50 relative to the mobile trend of this monitoring range or the physical location in this monitoring range change.

For example, described transmitter 21a ~ 27a is sequentially driven in turn with a time interval T, such as this time interval T is 1 millisecond (ms), and in other words, transmitter 21a closes after being driven 1 millisecond, changing to switch drives transmitter 22a to start, close after same 1 millisecond, then change driving transmitter 23a, the rest may be inferred, now, the overall switching frequency of described ripple 31 ~ 37 is 1000 hertz (Hz).When time interval T is enough little time, phase same-action when simultaneously opening close to whole transmitter 21a ~ 27a can be reached in fact.

Because the same time only has a transmitter to send ripple, therefore the operation of receiver 21b ~ 27b, no matter be sequentially drive in turn equally according to relation in groups, can operating state or all maintain, are all the modes that can operate for supervising device 10.If only consider power saving, then receiver and corresponding transmitter synchronization drive in turn is preferably embodiment.

When transmitter 21a ~ 27a is sequentially driven in turn with a time interval T, receiving by the number change of the described receiver of the described ripple reflected is often take turns calculating once, namely need setting one cycle, if the quantity M (the present embodiment M is 7) defining described transmitter 21a ~ 27a is multiplied by this time interval T and namely forms this cycle, and this supervising device 10 just can by the number change comparing the described receiver receiving the described ripple reflected by this first subject matter 50 in different cycles, judge such as whether patient first subject matter 50 leaves monitoring range, more can to arrange in pairs or groups further the combination of receiver and change thereof, accurately judge the mobile trend of the first subject matter 50.

And when the mobile trend of the first subject matter 50 exceeds a default door, this supervising device 10 just can produce an alerting.For example, as shown in Figures 5 to 7, because the first subject matter 50 continues to move in the same direction, extremely only ripple 31 is reflexed to receiver 21b by the first subject matter 50, and even finally all receiver 21b ~ 27b all fail any ripple reflected by the first subject matter 50 of perception, mean that this first subject matter 50 leaves monitoring range.If setting preset door be only have receiver 21b and 22b receive first subject matter 50 reflect ripple 31,32 time (as shown in Figure 7), when supervising device 10 to judge to sense by the receiver quantity of ripple that reflects from 3 being gradually reduced to 2 (follow-up more may be reduced to 0), and these 2 receivers are receiver 21b and 22b, namely reach default door, now just can produce an alerting immediately.But the setting of this default door can not be restricted at this according to user demand setting, as being also by mobile trend and default thresholds settings: can sense when being gradually reduced to 1 by the receiver quantity of the ripple reflected from 3, and be this receiver 21b at monitoring range edge, be also feasible embodiment.Wherein, this alerting can be the combination that a prompt tone, externally circulates a notice of signal or aforementioned signal.Prompt tone, except being the general synthesized voice preset, also can be the voice document that user records voluntarily.

In addition, supervising device 10 of the present utility model is also applicable to more complicated situation, refers to Fig. 8, and the aspect that continuity previous embodiment is provided with 7 groups of transmitter 21a ~ 27a and receiver 21b ~ 27b is described.When the first subject matter 50 is arranged in monitoring range, the ripple 33,34,35 that transmitter 23a, 24a, 25a are sent is reflected by the first subject matter 50 and received device 23b, 24b, 25b receive, and supervising device 10 can judge the position of the first subject matter 50.Now, if the second subject matter 55 (being such as medical personnel) enters monitoring range from outside, as shown in the figure, then the ripple 31 that transmitter 21a sends also can be reflected by the second subject matter 55 and received device 21b receives.Now, the receiver quantity receiving reflection wave is 4, and combination is 21b, 23b, 24b, 25b, but 22b does not then receive reflection wave, this quantity and combination, just may represent in monitoring range and have two subject matters.In other words, by receiving by the described quantity of receiver 21b ~ 27b of described ripple 31 ~ 37 that reflects and the change of combination, position and the mobile trend of multiple subject matter in monitoring range can be judged.

Be noted that especially, if the second subject matter 55 leaves monitoring range (being returned to the state shown in Fig. 5), receiver 21b can not sense that the ripple 31 that transmitter 21a sends is reflected, but owing to receiving by the number change of the described receiver of the described ripple reflected be: be reduced to 3 by 4 and namely no longer change, do not meet default door, therefore any alerting can not be produced.In other words, the utility model, by the design presetting door, accurately can judge the situation in monitoring range, and the situation that significantly can reduce erroneous judgement occurs.

In addition, when described ripple 31 ~ 37 is infrared light, extraneous sunshine, daylight lamp may be subject to or uses other infrared equipments to disturb, or also may disturb each other between ripple 31 ~ 37.Therefore, be preferably and make described transmitter 21a ~ 27a send described ripple 31 ~ 37 respectively to include a different coding, so can effectively get rid of aforementioned interference.Feasible mode is that described ripple 31 ~ 37 has different characteristic frequency respectively, when described receiver 21b ~ 27b accepts described ripple 31 ~ 37, then can carry out decoding and identification.

Further illustrate as follows about the coding of described ripple 31 ~ 37 and decoded mode, see also Fig. 9.For infrared light, the infrared light frequency of infrared light unit is about 38000 hertz (Hz) on the market at present, namely infrared light unit can launch infrared light in every 1/79000 second voluntarily, then stops transmitting 1/79000 second, and the cycle constantly circulates that this is reference wave W1 according to this.Because the reference wave W1 of each infrared light unit is identical, cannot mutually distinguish, so just need to add coding ripple W2.Figure 9 shows that the local of one of them ripple, coding ripple W2 opens infrared light unit 3/38000 second (sending the reference wave W1 in 3 cycles), then infrared light unit is turned off 3/38000 second (stopping launching base quasi wave W1 totally 3 cycles), circulate according to this, this can be considered the first coding ripple W2.The reference wave that another transmitter sends can be then open infrared light unit 5/38000 second (the reference wave W1 in 5 cycles), then infrared light unit is turned off 5/38000 second (the reference wave W1 in 5 cycles), by that analogy, and be considered as another kind of coding ripple W2.If each transmitter all has different coding ripple W2 (namely comprising the reference wave W1 of different cycles), can distinguish mutually.

Understandably, the reference wave W1 that Fig. 9 illustrates and coding ripple W2 is only the explanation of conveniently encoding, and its condition such as cycle and waveform is not used to limit the utility model.It is noted that, receiver 21b ~ 27b misjudgment is avoided in order to maintain the complete of coding ripple W2, the cycle of coding ripple W2 must be the integral multiple in reference wave W1 cycle, and practical operation in time interval T, need send enough reference wave W1 to form multiple complete coding ripple W2.Preferably, time interval T is the integral multiple in coding ripple W2 cycle, makes the coding ripple W2 sent in time interval T be all complete.When receiver 21b ~ 27b open and sense by reflect ripple 31 ~ 37 time, as long as judge that in the time interval T that opens, coding ripple W2 is whichever, then can Xie Code and judge that the ripple 31 ~ 37 actually for which transmitter 21a ~ 27a sent is reflected easily.

Above-mentioned design, all transmitter 21a ~ 27a and receiver 21b ~ 27b be all drive simultaneously time (namely keeping often opening), good difference effect can be produced, for example, when the ripple 32 that transmitter 22a sends is reflected by the first subject matter 50, in fact may not only go back to allow receiver 22b receive by complete righting reflex, the position of receiver 21b and 23b also may can receive by the ripple 32 reflected, but because it is the coding ripple W2 of a uniqueness that the ripple 32 that sends of transmitter 22a has, so receiver 21b and 23b just can distinguish after carrying out decoding, got rid of and avoided erroneous judgement.In like manner, if there are other to launch the electronic installation of infrared wave in monitoring range, also by the same manner, signal can be got rid of.

In addition, if transmitter is driven with receiver in turn by synchronous and cut out, owing to only having corresponding receiver 22b when transmitter 22a starts by synchronous averaging, other receiver is all cut out, and also can get rid of the problem receiving by mistake or judge by accident thus.
