Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.
Embodiment one
As shown in Figure 1, a kind of Intelligent crutch falls warning system, comprises crash sensor 1, for obtaining collision strength signal;
Touch sensor 5, for obtaining the touch signal that crutch handle is touched;
Control module 2, is connected with described crash sensor 1 and touch sensor 5 communication, and described control module 2, when described touch signal being detected, judges whether the intensity of described collision strength signal exceedes pre-set threshold value, if so, then exports control signal;
Warning device 4, is connected with the communication of described control module 2, and described warning device 4 reception control signal also starts to give the alarm;
Supply unit 3, powers for giving described crash sensor 1, touch sensor 5, warning device 4 and control module 2.
As shown in Figure 2, the Intelligent crutch of the present embodiment falls warning system, and its control method comprises the steps:
Step one, crash sensor 1 exports collision strength signal to control module 2;
Step 2, control module 2 gathers collision strength signal, and detects touch sensor 5 and whether produce touch signal, and if any touch signal, then control module 2 does not export control signal to warning device 4, as touch signal do not detected, enters step 3;
Step 3, control module 2 judges the signal intensity of collision strength signal, as described in the intensity of collision strength signal do not reach pre-set threshold value, then control module 2 does not export control signal to warning device 4, intensity as collision strength signal reaches pre-set threshold value, then enter step 4;
Step 4, control module 2 exports control signal to warning device 4, and warning device 4 gives the alarm.
Generally speaking, Intelligent crutch user is when falling or faint, and hand subconsciousness can unclamp crutch, and at this moment Intelligent crutch is answered and alarm, to attract the attention of pedestrian around and to provide assistance in time; And when normally using, namely user still grips crutch, no matter then how huge how or be subject to shock the attitude of crutch, should not give the alarm due to the erroneous judgement of warning system.
Based on this, the warning system of the present embodiment, by above-mentioned control method, by touch sensor 5, control module 2 experiences whether someone holds crutch in use; And whether crash sensor 1 is subject to violent vibrations in order to experience crutch, when crutch is subject to violent vibrations, shockproofness signal is passed to control module 2, then control module 2 judges whether to send to warning device 4 activation signal starting to report to the police by the touch signal gathering touch sensor 5, if touch signal do not detected, warning device 4 can send more sharp-pointed alarm sound to remind the attention of people around; If detect that crutch is touched, can not report to the police.
Wherein, the signal intensity pre-set threshold value of the collision strength signal described in the present embodiment is freely falling body intensity.Like this, only have Intelligent crutch to slip out of the hand and free-electron model time, warning device 4 just can work, and user slips out of the hand when putting Intelligent crutch normally, and this warning system is trigger alarm device 4 not.Certainly, also according to actual conditions or needs can be used, this pre-set threshold value is set as other intensity.
Control module 2 due to the present embodiment does not only experience the state of touch at touch sensor 5, judge that crash sensor 1 receives the collision strength data that crutch falls down to the ground and reaches pre-set threshold value simultaneously, just can send control signal trigger alarm device 4, fall and judge accurately, avoid the situation occurring wrong report.
It should be noted that, the warning system described in the present embodiment and control method thereof, the Intelligent crutch applied, include but not limited to all kinds of Intelligent crutchs such as old man's intelligent navigation crutch, blind walking-aid navigating walking stick.
Wherein, the control module 2 described in the present embodiment controls board-like control module for DSP.DSP control panel (digital singnal processor) is not only programmable, and the travelling speed of its real time execution many complicated order programs is high.As control module, the DSP control panel that the present embodiment adopts has logic judging function, has meaning for the response speed and decision accuracy improving this warning system.Certainly, described DSP control panel is known conputer controlled compute chip, does not repeat its concrete structure and principle of work here.
As shown in Figure 1, the supply unit 3 described in the present embodiment is provided with power switch 31.When power switch 31 closes, supply unit 3 with conduct with crash sensor, control module 2, touch sensor 5 and warning device 4, then Intelligent crutch has automatic drop warning function, uses as Intelligent crutch.When power switch 31 disconnects, then the Intelligent crutch being provided with this warning system also can be used as ordinary canes and uses, and which further improves the ease of use of crutch.
Wherein, the supply unit 3 described in the present embodiment is chargeable lithium cell.Lithium battery volume is little, lightweight, and electrical power storage amount is high, is suitable for the working environment of the present embodiment.
In a preferred embodiment, the control method of this warning system also comprises the steps:
Step 5, control module 2 detects touch sensor 5 and whether regenerates touch signal, and if any touch signal, then control module 2 stops exporting control signal, and alarm quits work, and as touch signal do not detected, then enters step 6;
Step 6, control module 2 timing detects touch sensor 5 and whether regenerates touch signal, and if any touch signal, then control module 2 stops exporting control signal, and alarm quits work, as touch signal do not detected, then circulation step six.
By above-mentioned step 5 and step 6, salvor or user can be in one's hands back Intelligent crutch time, this warning system is trigger alarm device 4 no longer, improves the dependability of Intelligent crutch.
Embodiment two
As shown in Figure 3, in another embodiment, a kind of Intelligent crutch, comprise handle 12 and cane bar 11, also include a warning system, described warning system comprises touch sensor 5, crash sensor 1, control module 2, supply unit 3 and warning device 4, and described touch sensor 5 is arranged at described handle 12 place.
In use, by touch sensor 5, the control module 2 of the present embodiment experiences whether someone holds crutch in use; And whether crash sensor 1 is subject to violent vibrations in order to experience crutch, when crutch is subject to violent vibrations, shockproofness signal is passed to control module 2, then control module 2 judges whether to send to warning device 4 activation signal starting to report to the police by the touch signal gathering touch sensor 5, if touch signal do not detected, warning device 4 can send more sharp-pointed alarm sound to remind the attention of people around; If detect that crutch is touched, can not report to the police.
It should be noted that, because the present embodiment Intelligent crutch be described in embodiment one falls a kind of Intelligent crutch of warning system embody rule, so the Intelligent crutch that the warning system described in the present embodiment is described in embodiment one falls warning system, repeat no more the principle of work of this warning system.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
