Abstract
The invention belongs to the field of electronic information and consumer electronics, and particularly provides an alarm clock with an ultrasonic ranging device. The alarm clock comprises ultrasonic probes, a shell, a controller, a loudspeaker, buttons, a fastening clip, and a fastening bolt. The ultrasonic probes are embedded into the lower part of the shell. The controller is mounted at the left side of the middle of the shell. The controller is connected with the ultrasonic probes. The loudspeaker is mounted at the right side of the middle of the shell. The loudspeaker and the controller are connected by an audio control line. The buttons are embedded into the right side of the middle of the shell, and the buttons are connected with the controller. The fastening clip and the fastening bolt are mounted above the shell. The fastening bolt is embedded into the middle of the fastening clip. The problem that the existing alarm clock cannot determine whether a person is lying in bed or not and cannot control on-off of the alarm sound intelligently is solved. Whether a user gets up can be judged accurately by the ultrasonic ranging probes, and the effects of intelligent wake-up and unprotected sleep prevention are achieved.
Description
Technical field
The invention belongs to electronic information and consumer electronics field, be specifically related to a kind of alarm clock with supersonic range finder.
Background technology
Current wakeup alarm clock is get up to the prompting that namely starts to pipe of a point mostly, until till having people to press to stop the switch piping; Or after a period of time that pipes, stop a period of time, if nobody presses shutdown switch, then continue to pipe.
In a word, current alarm clock judges that standard major part that whether people gets up has nobody to press to stop the switch piping.
This judgment mode is incomplete many times, incorrect.Such as, after someone presses shutdown switch, hit the tick in continuation; Or people gets up sometimes, and forget that pressing stopping pipes switch, then alarm clock still can continue to pipe.
In order to solve this shortcoming of current alarm clock, the present invention devises scheme ultrasonic ranging and alarm clock merged.
The principle of ultrasonic ranging is: ultrasonic probe sends the ultrasound wave propagated with the velocity of sound, returns and received by ultrasonic probe when running into obstacle.Now t of hyperacoustic travel-time can be calculated by controller.So current object distance ultrasonic probe distance be namely t*V 2 (V is the velocity of sound).Current, ultrasonic ranging is simple with its hardware configuration, and the higher advantage of accuracy is widely used in the middle of the equipment such as radar for backing car.
Namely design proposal of the present invention, installs ultrasonic ranging probe in the bottom of alarm clock, then alarm clock is installed the top with bed.So the distance obtained is measured after the distance that when people lies on a bed, ultrasonic ranging obtains can be less than.Thus " whether people gets up " is judged accurately, and then intelligentized control the tinkle of bells switch.
Summary of the invention
The object of the invention is to overcome alarm clock in prior art and accurately cannot judge the problem whether user has got up.
For this reason, the invention provides a kind of alarm clock with supersonic range finder, comprise ultrasonic probe, shell, controller, loudspeaker, button, anchorage clip, fastening bolt.Ultrasonic probe is embedded in the bottom of shell.Controller is arranged on left side in the middle part of shell.Controller is connected with ultrasonic probe.Loudspeaker is arranged on the right side of the middle part of shell.Loudspeaker is connected by audio frequency control line with controller.Button is embedded on the right side of the middle part of shell.Button is connected with controller.Anchorage clip and fastening bolt are arranged on the top of shell.Fastening bolt is embedded in the middle part of anchorage clip.
Above-mentioned a kind of alarm clock with supersonic range finder, controller adopts MSP430 series super low power consuming single chip processor, has adjustment button on the right side of the middle part of shell.
Beneficial effect of the present invention: this kind of alarm clock with supersonic range finder provided by the invention, comprises ultrasonic probe, shell, controller, loudspeaker, button, anchorage clip, fastening bolt.Ultrasonic probe is embedded in the bottom of shell.Controller is arranged on left side in the middle part of shell.Controller is connected with ultrasonic probe.Loudspeaker is arranged on the right side of the middle part of shell.Loudspeaker is connected by audio frequency control line with controller.Button is embedded on the right side of the middle part of shell.Button is connected with controller.Anchorage clip and fastening bolt are arranged on the top of shell.Fastening bolt is embedded in the middle part of anchorage clip.
Therefore, the present invention has can the function of distance between Accurate Determining alarm clock and user, and namely whether this alarm clock continues to pipe is the situation depending on whether real user gets up.Therefore the present invention has accuracy of judgement, do not affect by the lazy idea of user, can the advantage of real intelligentized control method the tinkle of bells switch.Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is a kind of alarm clock schematic diagram with supersonic range finder.
Description of reference numerals: 1, ultrasonic ranging probe; 2, shell; 3, controller; 4, loudspeaker; 5, button; 6, anchorage clip; 7, fastening bolt.
Embodiment
Embodiment 1:
There is an alarm clock for supersonic range finder, comprise ultrasonic probe 1, shell 2, controller 3, loudspeaker 4, button 5, anchorage clip 6, fastening bolt 7.Ultrasonic probe 1 is embedded in the bottom of shell 2.Controller 3 is arranged on left side in the middle part of shell 2.Controller 3 is connected with ultrasonic probe 1.Loudspeaker 4 is arranged on the right side of the middle part of shell 2.Loudspeaker 4 is connected by audio frequency control line with controller 3.Button 5 is embedded on the right side of the middle part of shell 2.Button 5 is connected with controller 3.Anchorage clip 6 and fastening bolt 7 are arranged on the top of shell 2.Fastening bolt 7 is embedded in the middle part of anchorage clip 6.
This alarm clock judges whether the standard whether user gets up does not have people's button, but the probe that arrives of ultrasonic ranging probe detection and the direct distance of bed board.When people lies on a bed, this distance be less than people get up after distance.Therefore the present invention can judge whether user gets up accurately, and then determine whether continue jingle bell.Solve current alarm clock and often accurately cannot judge whether user gets up, the tinkle of bells is not often rational especially problem.
Embodiment 2:
Controller of the present invention adopts MSP430 series super low power consuming single chip processor, has adjustment button on the right side of the middle part of shell.
Therefore, need practical of the present invention time, be fixed in the top of bed by the anchorage clip of shell upper and fastening bolt, the position that when preferably user lies down, chest is corresponding.Then, user arranges between WA by button and alarm clock mode etc.
Whether, when the clock of controller inside arrives between the WA of setting, ultrasonic ranging probe sends ultrasound wave, get up by calculating the Distance Judgment user obtained.If also do not got up, then loudspeaker sends the tinkle of bells; And after people gets up, cephalothorax usually can be upright, so the distance that now ultrasonic probe detects increases, the tinkle of bells stops.
Again owing to present invention employs super low power consuming single chip processor, so relative energy-saving, meet the modern life idea of environmental protection and energy saving.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
