Description

Navigation system

This creation is a navigation system, and in particular refers to a navigation system that can obtain power by wireless charging.

In museums, art galleries or other exhibition venues, in order to facilitate the public to understand the information about the exhibits, audio guide services are usually provided, as shown in Figure 1, which is a schematic diagram of a guided tour service. Usually, visitors will borrow the audio navigation device 1 from the counter at the exhibition hall. In general, the navigation device is attached to the earphone 11, or the sound information is output by the built-in speaker. After the visitor obtains the navigation device 1, the navigation device can be held to the guided object, and then the navigation device generates a corresponding voice description.

There are several ways to generate voice. One is that each object has a corresponding number. The user only needs to input the corresponding number to the navigation device, the navigation device will output the corresponding sound information; the other way is One side of the object is usually provided with a wireless transmitting component, such as an RFID. When the user holds the navigation device close to the object, the navigation device reads the wireless identification information sent by the RFID and recognizes it. Identify the sound information of the information.

However, in conventional navigation devices, the source of the power provided, as shown in FIG. 1, is mostly from the battery 12 within the navigation device 1. The battery 12 may be a rechargeable battery or a normal battery in a replaceable manner, or a built-in rechargeable battery that is directly charged by wire. Either way, since the navigation device needs to obtain power through the battery, there may be a problem that half of the power is not used, causing trouble to the user, or the battery is often charged or replaced. The problem of inconvenience in the manpower of the service work. In addition, the use of batteries can also cause environmental problems. Moreover, since the battery needs to be installed, the navigation device also has a certain volume, which may also cause inconvenience to the user.

The present invention provides a navigation system that can receive power from the outside in a wireless charging manner without using a battery, thereby eliminating the problem that the navigation device has no power or a battery. In addition, since the installation of the battery is dispensed with, it is possible to have an environmentally friendly effect and to reduce the volume of the navigation device.

In one embodiment, the present disclosure provides a navigation system including a navigation device and a wireless charging dock. The navigation device is configured to output navigation audio, and the navigation device has a wireless energy harvesting unit. A wireless charging stand with a sensor, a controller, and a wireless energy transfer unit. The sensor generates a sensing signal when detecting an object approaching. The controller is configured to generate a control signal according to the sensing signal. The wireless energy transfer unit generates power according to the control signal. Wherein, when the navigation device is placed on the wireless charging stand, the wireless receiving unit receives power generated by the corresponding wireless energy transmitting unit.

In another embodiment, the navigation system further has a wireless transmitting component disposed on a side of the navigation object for generating a wireless identification signal, and the navigation device receives the wireless identification signal and outputs the wireless identification signal according to the wireless identification signal. Corresponding navigation audio.

In another embodiment, the sensor is an ultrasonic sensor or an infrared sensor.

Referring to FIGS. 2A and 2B, the navigation device 2 of the present invention includes a navigation device 20 and a wireless charging stand 21. The navigation device 20 has a function of audio navigation. In the present creation, the navigation device 20 further has a wireless energy harvesting unit 201. In an embodiment, the wireless energy-receiving unit 201 is composed of a coil and a voltage-variable rectifying element, which are elements well known to those skilled in the art, and are not described herein.

The wireless charging stand 21 is disposed on one side of the guided object 90. The navigation object 90 of the present embodiment is a picture, but is not limited thereto. For example, a craft, a statue, a book, or a document may be used as an embodiment of the guided object. The wireless charging stand 21 has a base 213 on which a plurality of sensors 210 are disposed. In this embodiment, the sensor 210 is used to sense whether an object is close to, for example, sensing whether a user is approaching the guided object. The sensor 210 can be an ultrasonic sensor or an infrared sensor, as long as it can be used to sense whether the object is close, or even more, the distance between the object and the guided object can be detected. The implementation of the present sensor. It should be noted that the number of sensors is determined according to requirements, and is not limited by the number shown in FIG. 2A of the embodiment.

The sensor 210 is configured to generate a sensing signal when an object is sensed to be approached by the guided object. A controller 211 and a wireless energy transfer unit 212 are disposed in the base 213. The controller 211 is electrically connected to the sensor 210 and the wireless energy transfer unit 212. The controller 211 is configured to receive the sensing signal generated by the sensor 210. When the controller 211 receives the sensing signal, it represents that an object approaches the guided object, so the controller 211 generates a control signal to the wireless energy transmitting unit 212. When the wireless energy transfer unit 212 receives the control signal, it will start to generate the capability of wirelessly providing power. It is to be noted that the wireless energy transfer unit 212 is composed of a coil and a transformer rectifier element, and is well known to those skilled in the art, and will not be described herein. In addition, the number of wireless energy transfer units 212 can be determined according to requirements, and is not limited by the number shown in FIG. 2A. It should be noted that, on the mesa of the wireless charging stand 21, a certain indication may be set for each wireless energy transmitting unit 212 to facilitate the user to recognize the position of the wireless energy transmitting unit 212. In another embodiment, the light number can be set corresponding to the position of each wireless energy transmitting unit 212. Therefore, after the wireless energy transmitting unit 212 is activated, the light of the corresponding wireless energy transmitting unit 212 is illuminated. In order to facilitate user identification.

After the wireless energy transfer unit 212 is activated, in an embodiment, as shown in FIG. 3, the user carrying the navigation device 20 can place the navigation device 20 on the surface of the surface of the base 213 of the wireless charging stand 21. on. After the navigation device 20 is placed, the wireless energy transfer unit 212 corresponding to the navigation device 20 senses with the wireless energy receiving unit 201 of the navigation device 20, and transmits power to the wireless energy receiving unit 201. . Once the wireless receiving unit 201 receives the power, the function of the entire navigation device 20 is activated. In an embodiment, as shown in FIG. 2A and FIG. 3, the navigation device 20 reads the wireless signal emitted by the wireless transmitting component 91 on the side of the navigation object 90 to identify the content corresponding to the wireless signal. The corresponding navigation audio is then activated and the navigation audio is output. In one embodiment, the wireless transmitting component 91 is a radio frequency identification tag (RFID) for transmitting wireless RF signals to the near-field communication by the navigation device 20. In addition, in another embodiment, after the navigation device is activated, the user can directly input the number to the navigation device 20 according to the number of the navigation object, so that the navigation device 20 outputs the corresponding navigation. Audio. In addition, it is to be noted that the manner of outputting the audio may be output to the user through the earphone 202 connected to the navigation device 20, or directly through the surface of the navigation device 20 via the built-in speaker of the navigation device 20. Open the hole to output audio.
