Embodiment one
Figure 1A is the flow chart of the method for sitting posture adjustment prompting that the embodiment of the present invention one provides, and the present embodiment is suitable for intelligence
Energy desk lamp carries out user the situation of sitting posture adjustment prompting, and this method can adjust the device prompted to perform by sitting posture, the dress
Putting can be realized by the mode of software and/or hardware, and described device is configured in intelligent desk lamp, and the method for the present embodiment is specifically wrapped
Include following steps：
Step 110, when on intelligent desk lamp the first ultrasonic detector open when, pass through first ultrasonic detector
Obtain first shortest distance of first ultrasonic detector and user's head.
Wherein, ultrasonic detector is emitted using ultrasonic wave, passes through the time difference after the reflection of testee, echo reception
Tested distance is measured, precision of ultrasonic ranging can reach 0.5 millimeter.Ultrasonic detector emits ultrasound to a direction
Wave, the direction of the launch is different, and the distance between testee that ultrasonic detector measures also differs.For example, it can select
Angle is the ultrasonic detector of 15 degree of ultrasonic wave transmitting range.
Wherein, the first ultrasonic detector can be arranged on the lamp stand top of intelligent desk lamp.When user uses intelligent desk lamp
When, can be detected by the first ultrasonic listening between the first ultrasonic detector and the user's head on intelligent desk lamp away from
From.
Step 120 is closed when first ultrasonic detector, and the second ultrasonic detector on the intelligent desk lamp
During unlatching, the second of second ultrasonic detector and the user's head is obtained most by second ultrasonic detector
Short distance.
Wherein, second ultrasonic detector is set to the lamp stand bottom end of the intelligent desk lamp.When user uses intelligence
During desk lamp, it can be detected by the second ultrasonic listening between the second ultrasonic detector and the user's head on intelligent desk lamp
Distance.It is understood that the lamp stand top of intelligent desk lamp is at the position that lamp stand is connected with fluorescent tube, bottom end is lamp stand and pedestal
At the position of linking, ultrasonic detector is set at cohesive position, does not interfere with the beauty of intelligent desk lamp.Ultrasonic listening
Device can be set to lamp stand surface and can also be set to inside lamp stand, when being set to inside lamp stand, need to adapt on lamp stand
Setting trepanning in order to avoid ultrasonic wave is blocked.
When different ultrasonic detectors measure same testee, need to avoid because depositing between different ultrasonic waves
Interfere with each other and the problem of cause dysmetria true.It is understood that in order to ensure that data are interference-free, it can be
When the ultrasonic wave of one ultrasonic detector transmitting is all decayed to until can not detecting, the second ultrasonic detector is opened.Example
Such as, detector transmitting ultrasonic wave effective distance it is related with the transmission power of detector, using the detector of 6 meters of effective distances as
Example, the aerial spread speed of ultrasonic wave are 340 metre per second (m/s)s, then (6/340) * 1000=17.6, i.e., after 17.6 milliseconds
Ultrasonic wave is decayed completely substantially, thus can using 40 milliseconds as the first ultrasonic detector or the second ultrasonic detector from
It is opened into the time interval of closing.
The unlatching of ultrasonic detector can manually or automatically, illustratively, can pass through user's language
Ultrasonic detector is opened in sound instruction, such as opens intelligent desk lamp microphone, and voice adjustment is sent out when intelligent desk lamp receives user
During instruction, the first ultrasonic detector is automatically turned on, the ultrasound that the first ultrasonic detector emits after 40 milliseconds of time interval
Wave whole pad value can not detect, and the first ultrasonic detector is automatically closed；The second ultrasonic detector is automatically turned on simultaneously,
The ultrasonic wave whole pad value that the second ultrasonic detector emits after 40 milliseconds of time interval can not detect, and be automatically closed and the second surpass
Acoustic detector.
Step 130, when the change rate of first shortest distance described in the first setting time is in the range of first threshold, and
When the change rate of second shortest distance described in the second setting time is in the range of second threshold and when described second most short
When the difference of distance the first setpoint distance corresponding with normal sitting position exceeds third threshold range, then prompting user's sitting posture is sent
The information of adjustment.
Wherein, change rate is the ratio of two neighboring moment distance change amount and time interval.Such as at the 5th millisecond, obtain
First shortest distance taken is 25 centimetres, and when the 10th millisecond, second shortest distance of acquisition is 20 centimetres, then first most
Short-range variable quantity is -5 centimetres, and time interval is 5 milliseconds, then the change rate of first shortest distance is -1, and is no unit
Amount.The change rate of second shortest distance is the variable quantity of second shortest distance of adjacent moment and the ratio of time interval.
First setting time is the different or identical time ranges set according to actual user's sitting posture situation.First threshold
Value range is the threshold range of the change rate of first shortest distance, and first threshold range is predetermined, that is, can be according to reality
Border user's sitting posture situation predefine user first shortest distance the two neighboring period minimum and maximum change rate.Example
Such as, first shortest distance of normal condition of user's sitting posture is 30 centimetres, and within the period of 3 seconds, it is most short to deviate state every 1 second
Range data is followed successively by 29 centimetres, 26 centimetres, 30 centimetres, then can be [- 3,4] by first threshold range set.When at 3 seconds
In period, the change rate of first shortest distance is in [- 3, -4], the then shape that user during this period of time deviates in dynamic at this time
State.
It is understood that the second setting time, second threshold range and the first setting time, first threshold range class
Seemingly.Can second threshold range be predefined by the ranging of the second ultrasonic detector with actual user's sitting posture situation.And work as
When the change rate of user's second shortest distance in the second setting time is in the range of second threshold, determine user at this at this time
Section the time in dynamic deviate state, when determine user be in dynamic deviate state when do not send sitting posture adjustment prompting letter
Breath.
Third threshold range is the shortest distance and the deviation for user's normal sitting position that the second ultrasonic detector measures in advance
The difference range of the state shortest distance.When first setpoint distance is user's normal sitting position that the second ultrasonic detector measures in advance
The shortest distance.
The embodiment of the present invention is passed through by obtaining two sensors on intelligent desk lamp respectively to the distance of user's head
When two distances of acquisition meet preset condition, and one of distance and the difference of setpoint distance exceed given threshold range, then
The information of prompting user sitting posture adjustment is sent, can be in when dynamic deviates state in user's sitting posture to avoid intelligent desk lamp and frequently report
The problem of alert.
In a specific embodiment of the embodiment of the present invention, Figure 1B is that one kind that the embodiment of the present invention one provides is adopted
With the scheme of installation of ultrasonic detector, as shown in Figure 1B, two ultrasonic detectors of intelligent desk lamp can be made as follows
Setting：To prevent the first ultrasonic detector and the second ultrasonic detector from interfering with each other, need to open detector in turn, be spaced
Time is 40 milliseconds.According to actual user's sitting posture situation, the detector of 15 degree of ultrasonic wave transmitting ranges is selected, by the first ultrasound
Wave detector is set to lamp stand top, and the installation of user side, the setting of the second ultrasonic detector are directed toward with 15 degree under horizontal alignment
In lamp stand bottom end, the installation of user side is directed toward with 15 degree on horizontal alignment.
In order to ensure the reliability of data, 3 data can be taken to average to data and calculated, such as obtain first most
Short distance, can be taken in the range data measured the first ultrasonic detector three times the shortest distance average as first
The shortest distance.
Fig. 1 C are a kind of scene schematic diagrames using the detection of the first ultrasonic detector sitting posture provided in an embodiment of the present invention,
As shown in Figure 1 C, user starts to learn before table, and intelligent desk lamp is provided on desktop.The first ultrasonic wave for opening lamp stand top is visited
It surveys device to be detected the sitting posture of user, in user's head moving process, be obtained by the first ultrasonic detector in difference
Moment user's head obtains the first shortest distance a1, then judges in setting time to the distance of the first ultrasonic detector
Whether the change rate of interior first shortest distance is in the range of first threshold.
Head during according to user's actual learning is constantly towards situation about being moved close to the direction of desktop, and a1 is by normal sitting position
Corresponding first shortest distance is constantly decremented to the minimum value of first shortest distance under state, is then constantly incremented by, until user
Head reaches desktop.Assuming that with 1 second for time interval, in 3 second time, the changing value of a1 is [- 2 centimetres, 0) U (0,2 centimetre],
Then first threshold range is [- 2,0) U (0,2].The change rate of first shortest distance is in the first threshold in the first setting time
In the range of value, i.e., the change rate of first shortest distance continue for 3 seconds in [- 2,0) U (0,2].The process is that user's sitting posture is continuous
The scene of deviation.
It is change rate of the user in two neighboring first shortest distance of moment it is understood that when change rate is -2
Minimum value, the first ultrasonic ranging at this time obtain first shortest distance be minimum value.Therefore, beyond change rate [- 2,0) U
(0,2] range be [0] U [2, ∞], such as when change rate be 3 when, corresponding first shortest distance be more than normal sitting position institute it is right
First shortest distance answered, then it is assumed that for user's head far from the first ultrasonic detector, user's head is the state far from desktop.
Such as when change rate is 0, corresponding first shortest distance is equal to first shortest distance corresponding to normal sitting position, then it is assumed that uses
Account portion keeps corresponding first shortest distance of normal sitting position, and user keeps normal sitting position constant.
Fig. 1 D are a kind of scene signals using the detection of the second ultrasonic detector sitting posture that the embodiment of the present invention one provides
Figure as shown in figure iD, closes the first ultrasonic detector, opens the second ultrasonic detector positioned at lamp stand bottom end to user's
Sitting posture is detected, and takes the second most short distance that the second ultrasonic detector under the different moments of family moving-head measures
From b1, then judge the change rate of second shortest distance in the second setting time whether in the range of second threshold.
Head during according to user's actual learning is constantly towards situation about being moved close to the direction of desktop, and b1 is by normal sitting position
Corresponding second shortest distance is constantly successively decreased, until user's head reaches desktop.With 1 second for time interval, within 3 second time,
The changing value of b1 for [- 2 centimetres, 0), then first threshold range be [- 2,0).The described second most short distance in the second setting time
From change rate in the range of second threshold, i.e., the change rate of second shortest distance [- 2,0) in continue for 3 seconds.The process is
The scene that user's sitting posture constantly deviates.
And it is understandable that and refers to that change rate is 0 beyond second threshold range.
Fig. 1 E are the scene schematic diagrames of the second ultrasonic detector of another kind sitting posture detection that the embodiment of the present invention one provides,
As referring to figure 1E, second shortest distance that can be measured according to the second ultrasonic detector, judge second shortest distance with it is normal
Whether the difference of corresponding first setpoint distance of sitting posture exceeds third threshold range.
It is installed since the second ultrasonic detector is directed toward user side with 15 degree on horizontal alignment, angle can be ignored not
Meter, then it is the difference of second shortest distance the first setpoint distance corresponding with normal sitting position that can determine threshold range described in third
Value, i.e. b2-b1, head during according to user's actual learning is constantly towards situation about being moved close to the direction of desktop, third threshold value
Range can be [0,10 centimetre).
The mode of traditional intelligent desk lamp sitting posture adjustment prompting is to set a ultrasonic detector, for measuring ultrasound
The distance between wave detector and user's sitting posture, as long as user's sitting posture distance and normal sitting position, apart from inconsistent, intelligent desk lamp is
Alarm is sent out to remind user.In this way set the defects of be, for user in learning process, sitting posture is dynamic change, with
During the sitting posture dynamic change of family, if the sitting posture of the user a certain moment deviates, subsequent time sitting posture may just restore normal, this
When alarm the user of quiet study may to cause to frighten, interfere the normal study of user, user experience is bad.
And the specific embodiment of the embodiment of the present invention changes according to practical sitting posture of the actual user in learning process
Situation, state is deviateed to the sitting posture of user and carries out many condition limitation, meets preset condition, and wherein one when obtaining two distances
When a distance and the difference of setpoint distance exceed given threshold range, then the information of prompting user sitting posture adjustment is sent, it can be to avoid
Intelligent desk lamp is in the problem of frequently alarming when dynamic deviates state in user's sitting posture.
