Abstract
The invention discloses a tracking method of fallen mobile electronic equipment. The mobile electronic equipment is internally embedded with an acceleration transducer connected with a microprocessor; when the microprocessor detects that the mobile electronic equipment is at a falling state by the acceleration transducer, the microprocessor sends a control signal to an alarming module so as to send alarming information; the judging standards for the falling of the mobile electronic equipment are as follows: no acceleration in any direction at any moment is detected by the acceleration transducer, and then acceleration which is more than g in any direction is detected within the subsequent time; and then the acceleration which is more than g in any direction is detected within the subsequent time and kept for at least 0.5 second. By using the method provided by the invention, practical convenience is provided for a user. The invention also discloses mobile electronic equipment.
Description
Technical field
The present invention relates to the method for tracing after a kind of mobile electronic device falls.The invention still further relates to a kind of mobile electronic device.
Background technology
Portable mobile electronic device as mobile phone, password protection, game paddle, telepilot, wireless mouse, laser pen etc., brings people a lot of convenience.Therefore kind equipment all has small and exquisite characteristics, thereby also has easy loss and ND shortcoming simultaneously.For example, generally mobile phones such as mobile phone can be placed on one's body or fixing position, so that seek; But mobile phone is in a position at random then using or carrying in the process and might drop.And the user looks for the process of mobile phone is time-consuming effort.
Summary of the invention
The technical problem to be solved in the present invention provides the method for tracing after a kind of mobile electronic device falls, residing position after it can effectively point out mobile electronic device to fall.
For solving the problems of the technologies described above, method for tracing after mobile electronic device of the present invention falls, this mobile electronic device is embedded with acceleration transducer that is connected with microprocessor and the alarm module of being controlled by microprocessor, when microprocessor detected mobile electronic device and is in fall condition by acceleration transducer, microprocessor sent control signal and gives alarm module to send information warning; The criterion that mobile electronic device falls is: at a time described acceleration transducer detected acceleration on any direction is 0, upwards detect acceleration greater than g in any one party at subsequently 0.1-10 in second, and after 0.01-10 detect any one party in second upwards for the acceleration of g and kept at least 0.5 second.
Mobile electronic device of the present invention, this mobile electronic device comprise acceleration transducer, microprocessor and the alarm module that connects successively; Described acceleration transducer is used to detect the state of described mobile electronic device, and will detect information transmission and give microprocessor; Described microprocessor is used for judging by the acceleration transducer detection information that receives whether described mobile electronic device falls, then send control information in this way to shown in alarm module send information warning.
Method for tracing after mobile electronic device of the present invention falls, by embedded acceleration transducer in mobile electronic device, value by the microprocessor calculating sensor is determined the residing state of mobile electronic device, and a certain moment is detected acceleration of gravity disappear, and in a period of time subsequently in any one party to the acceleration of gravity that detects greater than g, after 0.01-10 detect any one party in second upwards for the acceleration of g and kept at least 0.5 second, the criterion of falling as mobile electronic device.After detecting the falling process of equipment, send information warning by alarm module (can be boombox), remind falling of this mobile electronic device of user, and the mobile electronic device that helps the user location to be fallen.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the schematic flow sheet of method for tracing of the present invention;
Fig. 2 is the structured flowchart of mobile electronic device of the present invention.
Embodiment
Method for tracing after mobile electronic device of the present invention falls, degree of will speed up sensor places mobile electronic device, is connected with microprocessor, simultaneously, the microprocessor (see figure 2) that links to each other with alarm module.Can periodically obtain the parameter of acceleration transducer (being preferably three acceleration of gravity sensors) by the computer program in the microprocessor, promptly can obtain this mobile electronic device, the acceleration of y and three directions of z at x.Micro-acceleration sensor is a kind of of MEMS (micro electro mechanical system) (MEMS), and its volume is very little, has only the part of nail cover big, can be placed in the mobile electronic device in order to parameters such as the relative position of checkout equipment in the space, acceleration.Particularly, microprocessor can obtain a sequence on the time shaft from acceleration transducer, each point on this sequence be this mobile electronic device should the time at the acceleration of x, y and three directions of z: (x
0, y
0, z
0), (x
1, y
1, z
1) ..., (x
t, y
t, z
t), wherein, t is the time.When mobile electronic device remained static, microprocessor detects can arrive it has big or small g in certain direction acceleration of gravity.In case and this mobile electronic device falls, acceleration of gravity on this this direction of moment disappears, and in a period of time subsequently, will detect acceleration (constantly in certain direction corresponding to bump greater than g, the detected information of acceleration of gravity), the acceleration that detects a certain direction within the certain hour after bump takes place is g and keeps at least one special time.When can being in other states with mobile electronic device at an easy rate, this feature distinguishes as keep flat, rock, shake, the normal use of quilt etc.Therefore, in the method for tracing after mobile electronic device of the present invention falls, will " at a time described acceleration transducer does not all detect acceleration on any direction; and subsequently 0.1-10 second (be preferably 0.3-3 second) inherent any one party upwards detect acceleration greater than g; at bump 0.01-10 detects a certain direction within second acceleration taking place is g and kept at least 0.5 second " be defined as the mobile electronic device peculiar pattern in the process of falling, this is differentiated for basis for estimation, after microprocessor detects this information, send control information and make the information warning (see figure 1) to alarm module.Information warning can provide by the form of sounding, realizes as sending chimes of doom continuously or periodically by loudspeaker in the mobile electronic device.Information warning also can realize by the light-emitting caution lamp, as makes warning lamp luminous, or warning lamp is extinguished etc.
In case microprocessor system detects the acceleration model that falls, judge that just mobile electronic device falls.This moment, its control loudspeaker was disposable or periodically send a section audio to loudspeaker, the specific alarm song that its broadcast is continued for some time.According to alarm song, the user can know that equipment falls, and can locate its position according to judging that sound is originated.
Method of the present invention is an embedded acceleration transducer in mobile electronic device, determine the residing fall condition of mobile electronic device by microprocessor according to the information of sensor, and detect fall after, send information warning (as prompt tone) by alarm module by loudspeaker plays a period of time, remind user's device fall, and help the user to locate the position of mobile electronic device.
