Description

Sonar type object-seeking system and implementation method thereof

A searching system for searching for a relative position of a physical object within a certain range. The present invention particularly relates to a portable electronic device, and uses a voiceprint database as a basis for comparison to achieve accurate sound searching. Nano-type object-seeking system and its implementation method.

At present, the electronic application device that can be carried around is mainly based on RFID. The reason is that the application of RFID conforms to the requirements of miniaturization and lightness. The common object-seeking device mainly consists of a sensing device and at least one label ( TAG) is configured. When implementing, the user needs to first attach the label to a specific object, such as a key, a leather bag, etc., since the label and the sensing device have completed the frequency matching in advance, the user After the sensing device is turned on, it is possible to actively monitor whether the specific object is within the effective monitoring range. If the distance between the specific object and the sensing device exceeds the preset range, the sensing device generates, for example, sound or light flashing. Warning to remind the user that the specific item is out of the scope of monitoring. The common use is mostly used in small sizes that can be easily taken. Articles, there are also inventors applying this technology to the prevention of child loss monitoring; however, this type of object-seeking device has its problems in implementation. First, the operator needs to carry another sensing device, and needs a Or a plurality of tags, if there are multiple objects to be monitored, when the sensing device issues a warning, the operator often cannot correctly know what the object (person) left the monitoring range, and further, this type of object-seeking device Only the warning can be issued, and the relative position between the monitored object and the operator cannot be immediately and correctly known. If the monitored object happens to be covered by other objects, the user still cannot find the monitored object; Therefore, the inventor is actively researching whether other technologies can be applied, so that the object-seeking device (system) can provide the operator with quicker and more accurate access to the object to be monitored; thereby, the inventor mainly selects Based on the application of the principle of sound waves, as the basis for sensing the object, the inventor and the relevant basic technology are used as a reference for the invention. However, after multiple searches, there are related technologies. For the discretion, but the technology currently seen can not be completely simple and practical; currently known technology of the object-seeking device can be roughly divided into two types: (1) two-way signal transmission type of device: need to be a signal transmitter and a The signal receiver is matched, that is, the monitored object itself must be loaded with any one of the signal transmitter or the signal receiver to form a two-way signal sensing effect, which is extremely inconvenient to implement, and if it is random Sexual search, the conventional technology is obviously impossible to achieve, for example, the operator is looking for a TV remote control within a certain range (such as in the living room), if the TV remote control is not equipped with signal transmission in advance Any one of the devices, or the signal receiver, obviously cannot be achieved by conventional techniques. For example, the Republic of China Patent Open Publication No. 200818845 "Methods for Searching by Using Mobile Communication Devices and Related Shaped Communication Devices"; Republic of China New Patent No. M395226 "Collaborative Device for Providing Items by Electronic Objects" (2) One-way type object-seeking device: At present, the principle of applying ultrasonic waves is mainly used, for example, US Patent Publication No. 2013/0003502 "configurable ultrasound measurement logic in a moible computing", which discloses related technologies, but this technology only It can be used for specific purposes, for example, by monitoring the heart rate of a baby in a uterus, the distance of a single target object by an ultrasonic transceiver, and the like, and the "sound wave identification system and method" of the Republic of China Patent Publication No. 201142820 is used to identify a specific material.

It can be seen that the related technologies currently uncovered cannot be universally applied in daily life.

As can be seen from the above, the existing technology of the related object-seeking device can not fully meet the needs of the portable, instant and accurate providing operator to quickly find the object to be monitored.

In view of the above needs, the inventors have made correlations based on user experience, habits, etc. based on years of experience in designing related products. The research and analysis can design a more practical product; accordingly, the main object of the present invention is to provide a sonar-type object-seeking system that can provide an operator with a quick and easy access to the object to be monitored. Its implementation method.

In order to achieve the above objectives, the system referred to in the present invention mainly uses the principle of sound wave as a basis for sensing the object, and uses sonar technology, a sonar application, and a voice database to operate. The method of searching for objects can be performed in the quickest and simple manner; further, the method for implementing the system of the present invention utilizes the principle of active sonar to emit sound waves by the sonar module, and simultaneously collect and detect sound waves. The rebound sound wave after the physical object is compared with the voiceprint data stored in the voiceprint database, and the relative position of the physical object to be found is directly displayed on the screen of the portable electronic device.

Step 34: In the step of ascending, when the probe sound wave S hits any physical object P in the field, a rebound sound wave R is generated, and the physical material P of different materials has a rebound. The wavelength of the sound wave (or sound grain) is different. As shown in the figure, when the sound wave S hits the physical object P in the scene environment, several rebound sound waves (R1, R2, ...) are generated. The sonar application 12 then drives the radio unit 114 to receive the rebound sound waves (R1, R2, ...) returned by the scene (please refer to "1st picture" and "figure 5"), (5) one tone ratio Step 35: According to the step, the voiceprint matching unit 14 performs the voiceprint on the received rebound sound waves (R1, R2, ...) based on the selected voiceprint data 131 in the voiceprint data selection step 32. (6) One position presentation step 36: bearing, after comparison, when one of the rebound sound waves R conforms to the preset voiceprint data 131, this is where the physical object P that has been found is located Position, and in combination with the central processing unit 111, calculate the relative distance D between the physical object P to be found and the portable electronic device 11, As a base range display area 1211 of the menu 121, a mark icon M1 is generated (please refer to "FIG. 6". As shown in the figure, a cross-axis center position M represented by the base range display area 1211 is a portable electronic device. The position of the device 11 and the position indicated by the symbol M1 are the relative positions of the physical object P and the portable electronic device 11 (please refer to "FIG. 6").
