As shown in FIG. 3, the power transmission device 100 of this embodiment includes a coil 101, a commercial power source 102, a rectifying / smoothing unit 103, a DC / DC converter 104, a power transmission control unit 105, a power transmission coil excitation unit 106, a power transmission operation unit 107, The display unit 108 and the communication unit 110 are included. The communication unit 110 includes a data processing unit 111, a signal processing unit 112, and an antenna 113.

  On the other hand, the charging device 200 includes a charging coil 201, a rectifying / smoothing unit 202, a charging control unit 203, a secondary battery 204, and a communication unit 210. Further, the communication unit 210 includes an antenna 211, a signal processing unit 212, a communication control unit 213, and a memory 214.

Next, functions of the power transmission device 100 and the charging device 200 will be described.
The AC voltage from the commercial power source 102 is rectified and smoothed by the rectifying / smoothing unit 103 and converted to a DC voltage, and the DC voltage is supplied to the DC / DC converter 104. The DC / DC converter 104 converts the input DC voltage into a predetermined voltage and sends it to the power transmission control unit 105.

  The power transmission control unit 105 is a control unit including a microcomputer and a memory, and controls whether or not to output the DC voltage sent from the DC / DC converter to the power transmission coil excitation unit 106. When a DC voltage can be output to the power transmission coil excitation unit 106, the voltage is output by turning on a switch for controlling the power transmission coil excitation unit 106.

  The power transmission coil excitation unit 106 excites the power transmission coil 101 based on the DC voltage supplied from the DC / DC converter 104 via the power transmission control unit 105 and changes the magnetic flux generated by the coil 101 to the charging device 200. In contrast, power is supplied in a non-contact manner.

  The power transmission operation unit 107 includes a switch for performing the overall operation of the power transmission device 100 such as the output of the power transmission device 100 and the operation of the LCD panel. The display unit 108 displays various types of information to the user in addition to the information on the moving direction and distance of the charging device 200 as described above.

  The communication unit 110 separates the necessary data after demodulating the received signal from the data processing unit 111 that processes the communication data necessary for the power transmission control unit 105. A signal processing unit 112 that performs necessary processing at the time of transmission and then converts the signal into a signal suitable for communication, and an antenna 113 that receives and transmits an electromagnetic wave signal are provided.

  With these functions, the communication unit 110 can exchange information with the communicable charging device 200. The communication unit 110 can be realized using an existing communication technology, and for example, a technology such as BlueTooth, wireless LAN, or Wi-Fi can be used.

  On the other hand, charging device 200 communicates with antenna 113 of power transmission device 100 through antenna 211 of communication unit 210. In the signal processing unit 212, predetermined processing is performed on data to be transmitted / received, and the data is converted into processing data or converted into a form in which data can be transmitted.

  The communication control unit 213 performs an operation of exchanging necessary data from the charging control unit 203 or sending necessary data to the charging control unit 203. The memory 214 stores data necessary for controlling the charged part.

  An electromotive force is generated in the coil 201 by the magnetic flux generated from the coil 101 of the power transmission apparatus 100, and a current flows through the coil 201. Since the voltage supplied to the coil 201 is not stable, it is rectified and smoothed by the rectifying and smoothing unit 202, and the DC voltage is supplied to the secondary battery 204 via the charging control unit 203 and charged.

  Note that the charging control unit 203 detects the state of the secondary battery 204 based on the voltage of the secondary battery 204, the charging time, and the like, and controls the supply of power to the secondary battery. For example, the secondary battery 204 is a secondary battery such as a lithium ion battery or a lithium hydrogen battery that stores electric power.

  In this embodiment, the magnetic sensor unit 205 is a magnetic sensor using a magnetic detection element such as a Hall sensor. The magnetic sensor unit 205 includes four magnetic sensors, ie, magnetic sensors 205a, 205b, 205c, and 205d arranged at separate locations. These four magnetic force sensors 205 a to 205 d detect magnetic flux (magnetic force) generated by the coil 101 of the power transmission device 100 and send the output result to the charging control unit 203. The charging operation unit 206 includes various switches for switching the charging state of the charging device 200 and performing other operations of the charging device 200 in general.

Next, the processing flow of the present embodiment will be described using the flowchart of FIG.
When starting non-contact charging, first, the power transmission device 100 and the charging device 200 are switched to the charging mode using the power transmission operation unit 107 and the charging operation unit 206, respectively. At this time, the power transmission device 100 excites the coil 101 with an output and frequency suitable for the alignment processing, and the charging device 200 receives the output of the magnetic force sensor unit 205 by the charging control unit 203 (step S401). Next, the charging device 200 is placed on the power transmission device 100 and enters the alignment sequence (step S402).

  Here, the description of the flow of processing using the flowchart of FIG. 4 is temporarily interrupted, and the positional relationship between the magnetic sensor and the coil, and the positional relationship between the power transmission device 100 and the charging device 200 in the alignment sequence are shown in FIG. Use and explain.

  FIG. 5 schematically shows the positional relationship between the power transmission device 100 and the charging device 200 during the alignment sequence, and the positional relationship between the coil 201 and the magnetic sensors 205a, 205b, 205c, and 205d in the charging device 200. is there. In FIG. 5, the charging device 200 is intentionally drawn large for easy understanding.

  As shown in FIG. 5, four magnetic sensors 205a, 205b, 205c, and 205d are arranged in a right-angled positional relationship from the center of the coil 201 of the charging device 200, respectively, and a position that is equally spaced from the coil center by a distance a. It has become. As shown in FIG. 1, in the present embodiment, the charging device 200 is assumed to be a digital camera. When the digital camera is placed on the power transmission device 100 as shown in FIG. 6, the coil 201 and the magnetic force sensors 205a to 205d are arranged as shown in FIG. 5 on a surface substantially parallel to the bottom surface of the digital camera. .

  The line connecting the magnetic sensor 205a and the magnetic sensor 205b is parallel to the direction (1) in FIG. 6, and the line connecting the magnetic sensor 205c and the magnetic sensor 205d is parallel to the direction (2) in FIG. Yes. In this embodiment, the direction (1) in FIG. 6 is parallel to the long side direction of the power transmission device 100, and the direction (2) in FIG. 6 is parallel to the short side direction of the power transmission device 100. It is assumed that the charging device 200 is moved.

  In FIG. 5, the distance between the coil 101 of the power transmission device 100 and the coil 201 of the charging device 200 is r. Further, the distance between the coil 101 of the power transmission device 100 and the magnetic force sensor 205a of the charging device 200 is r1, and the distance between the coil 101 of the power transmission device 100 and the magnetic force sensor 205b of the charging device 200 is r2. In addition, an angle formed by a line segment formed by the magnetic sensor 205a and the magnetic sensor 205b and a line segment formed by the coil 101 and the coil 201 is denoted by θ.

Returning to the description with reference to the flowchart of FIG.
In step S403, the values detected by the magnetic sensors 205a, 205b, 205c, and 205d are sent to the charging control unit 203. Here, the charging control unit 203 recognizes the difference between the maximum value and the minimum value within a certain time as the output amplitude.

  This will be described with reference to FIG. For example, assuming that the outputs from the magnetic force sensors 205a and 205b are as shown in FIGS. 7A and 7B, the width formed by the maximum value and the minimum value indicated by dotted lines is set as the output amplitude.

  Next, the output amplitude recognized by the charging control unit 203 is transmitted to the power transmission device 100 via the communication unit 210 (step S404). Here, in the power transmission device 100, the power transmission control unit 105 receives communication data from the communication unit 110, and obtains four output amplitudes of the magnetic force sensors 205a, 205b, 205c, and 205d.

  Next, the process enters a direction / distance calculation process (step S405). In the direction / distance calculation processing, the distance and direction between the coil 101 of the power transmission device 100 and the coil 201 of the charging device 200 are calculated using the outputs of the four magnetic force sensors. This calculation is performed using the following equations (a) to (g).

  When the output amplitude of the coil 101 for power transmission is constant, the magnetic flux density in the magnetic force sensors 205a and 205b can be expressed by the equations (a) and (c) with β as a constant. A modification of these is the equations (b) and (d).

  From the positional relationship of FIG. 5, if the triangle midline theorem is used, a, r, r1, and r2 are in the relationship of equation (e). Expression (f) is obtained from the expressions (b), (d), and (e) described above. Further, the equation (g) is obtained from the triangular cosine theorem and the equations (b) and (d). By the equations (f) and (g), the distance and direction of the coil 201 toward the coil 101 can be obtained.

  At this time, the calculation method described above is indistinguishable from the case where the coil 101 is in a line-symmetrical position with respect to the line segments formed by the magnetic force sensors 205a and 205b when viewed from the charging device 200 in FIG. Become. Here, the output amplitude of the magnetic force sensors 205c and 205d is compared, and the position of the coil 101 is specified by determining which side the coil 101 is with respect to the line segment formed by the magnetic force sensors 205a and 205b according to the magnitude can do. The power transmission control unit 105 of the power transmission device 100 performs the above calculation process.

  After performing the direction detection process / distance calculation process, the calculated movement direction and distance information is displayed on the display unit 108 (step S406). Specifically, an arrow for a corresponding movement is displayed on the display unit 108 according to the calculated direction and distance values.

  FIG. 8 is a diagram illustrating an example of information displayed on the display unit 108 at this time, and the display unit 108 functions as an image display unit. Here, the direction of the arrow changes depending on the direction calculated in step S405, and the length of the arrow changes according to the distance calculated in step S405. In this embodiment, as shown in FIG. 2, since the normal direction of the screen of the display unit 108 is in the horizontal direction, the arrows taking into account the depth as shown in FIGS. It is displayed.

  After the movement direction / distance display is performed, the process performed by the user according to the instruction of the display unit 108, that is, the process of moving the charging device 200 on the power transmission device 100 is detected (step S407). Thereafter, it is determined whether the magnetic force for charging the charging device 200 is sufficiently supplied (step S408). The determination in step S408 is performed by the power transmission control unit 105 after the power transmission device 100 obtains the amplitude obtained from the magnetic force sensor unit 205 via the communication unit 210 and the communication unit 110.

  If a sufficient output is obtained as a result of the determination in step S408, the display unit 108 displays the display shown in FIG. 8C, and the power transmission control unit 105 has an amplitude suitable for charging the power transmission coil excitation unit 106. Instruct to start excitation at frequency. The charging device 200 also ends the alignment sequence in accordance with a communication instruction from the power transmission device 100 and enters a charging operation.

  On the other hand, if it is determined as a result of the determination in step S408 that a sufficient magnetic force supply has not been obtained, the process returns to step S403, and the alignment sequence process is subsequently repeated.

  That is, each time the user moves the position of the charging device 200 based on the information on the direction and distance displayed on the display unit 108, it is determined whether or not the user has been placed at the optimum position. If it is not the optimum position, the moving direction and distance are calculated again, and the information is displayed on the display unit 108. Therefore, the user can intuitively understand in which direction the charging device 200 can be moved to a position suitable for charging according to the instruction of the display unit 108.

  In this embodiment, the direction / distance calculation processing is performed by the power transmission control unit 105 on the power transmission device 100 side, but may be performed by the charging control unit 203 on the charging device 200 side. In the present embodiment, the magnetic force sensors 205 a to 205 d are provided in the charging device 200, and the display unit 108 is provided in the power transmission device 100. However, as illustrated in FIG. 10, a configuration in which the magnetic sensor 100 a is provided in the power transmission device 100 and the display unit 200 a is provided in the charging device 200 may be employed.

  Even in this configuration, the coil 201 of the charging device 200 is excited at the time of alignment, and the magnetic flux density by the coil 201 is detected by the magnetic force sensor unit 100a of the power transmission device 100, thereby conforming to the present embodiment. The alignment process can be performed in the process. In this case, the normal direction of the display surface of the display unit 200a included in the charging device 200 may be a horizontal direction or a vertical direction.

  At this time, when the display surface is oriented in the horizontal direction, an arrow is displayed in consideration of the depth as shown in FIG. However, when the display surface is oriented in the vertical direction, an arrow may be displayed that does not consider the depth as shown in FIG. This may be determined by the charging device depending on the relationship between the orientation of the charging coil and the orientation of the display surface, or by providing the charging device with an orientation sensor, the two displays described above depending on the orientation. The form may be changed.

  In this embodiment, the distance and direction are calculated based on the detection output difference between the plurality of magnetic force sensors 205a to 205d. However, for example, a single magnetic force sensor and an acceleration detection sensor such as a sensor that detects the movement of the charging device are combined. It is also possible to implement the present invention.

  Further, in the present embodiment, the power transmission device 100 is written as an installed device, and the charging device 200 is written as a portable device. However, for example, the case where both are portable devices can also be implemented. In this case, both of them may have both power transmission and charging functions.

  Further, in the present embodiment, the direction / distance calculation processing is performed by the mathematical expression represented by Equation 1, but other appropriate calculation processing may be performed. For example, as shown in FIG. 12 for the output of each magnetic sensor, threshold values of several levels are prepared and the value of the level to be applied is held as an output value.

  Thereafter, in FIG. 5, the output difference between the magnetic sensors 205a and 205b is set as a horizontal vector in FIG. 5, and the output difference between the magnetic sensors 205c and 205d is set as a vertical vector in FIG. May be. In this case, for example, a distance may be estimated by taking an average value of four sensor detection outputs.

  Further, in FIG. 12, the threshold value for dividing the output value by the values indicated by a, b, c, d, e, and f is determined. However, even if a value equal to these values is used, the contactless charging is actually performed. Different values may be used by using values in accordance with

  Further, in this embodiment, when it is confirmed that a magnetic force output of a certain level or more suitable for charging is obtained, charging is automatically performed. However, when it is confirmed that a magnetic force output of a certain level or more is obtained, the output values of the magnetic force sensor 205a and the magnetic force sensor 205b are quantitatively displayed in real time as shown in FIG.

  Then, after the user makes a fine adjustment while watching this display, the charging state may be manually switched through the charging operation unit 206 or the power transmission operation unit 107. In the present embodiment, the display unit 108 is configured to issue a movement instruction to the user using an image. However, a voice instruction unit that generates a voice instruction by sounding the movement instruction may be provided. .

(Second Embodiment)
FIG. 13 is a diagram showing an outline in the second embodiment of the present invention.
A power transmission device 300 that supplies power without contact includes a charging coil 301. In addition, the charging device 400 that charges the battery in a non-contact manner charges the charging coil 401 that receives power from the power transmission device 300, the magnetic sensor unit 405 that detects the magnetic flux (magnetic force) generated by the power transmission device 300, and the charging device 200. A display unit 407 for displaying an instruction to move to a suitable position is provided.

  In this embodiment, the magnetic force generated by the coil 301 is received by the magnetic sensor unit 405, the direction and distance suitable for charging are calculated based on the detection output, and the display unit 407 prompts the user to move the charging device 400. It has become.

  FIG. 14 is a block diagram of a power transmission device and a charging device according to the second embodiment. Each block shown in FIG. 14 has substantially the same function as the corresponding block in FIG. A major difference from the block diagram in FIG. 3 is that neither the power transmission device 300 nor the charging device 400 has a communication unit. In addition, the display unit 407 is provided not on the power transmission device 300 side but on the charging device 400 side.

The processing flow of this embodiment will be described with reference to FIG.
When starting non-contact charging, first, the power transmission device 300 and the charging device 400 are switched to the charging mode using the power transmission operation unit 307 and the charging operation unit 406, respectively. At this time, the power transmission device 300 excites the coil 301 with an output and frequency suitable for the alignment processing, and the charging device 400 receives the output of the magnetic force sensor unit 405 by the charge control unit (step S1501). Next, the charging device 400 is placed on the power transmission device 300 and enters the alignment sequence (step S1502).

  In step S1503, the output values detected by the magnetic sensors 405a, 405b, 405c, and 405d are sent to the charging control unit 403. Here, as in the first embodiment, the charging control unit 403 recognizes the difference between the maximum value and the minimum value within a predetermined time as the output amplitude.

  Subsequently, the process enters a direction / distance calculation process (step S1504). In step S1504, the direction and distance from the output of the four magnetic sensors 405a to 405d obtained in step S1503 to the position suitable for charging from the position where the charging device 400 is currently placed, as in the first embodiment. Is calculated by the charging control unit 403.

  In step S1504, after the direction / distance calculation processing is performed, the moving direction / distance display is performed (step S1505). Next, according to the direction and distance data calculated in step S <b> 1505, a corresponding movement arrow is displayed on the display unit 407. The display form at this time performs display according to the first embodiment.

  After the movement direction / distance display is performed, the user moves the charging device 400 on the power transmission device 300 in accordance with the instruction of the display unit 407 (step S1506). Thereafter, the charging control unit 403 determines whether the magnetic force for charging the charging device 400 is sufficiently supplied from the output result of the magnetic force sensor unit 405 (step S1507).

  If a sufficient output is obtained as a result of the determination in step S1507, the display shown in FIG. 8C is made on the display unit 407, and the charging control unit 403 enters the charging operation. When the display shown in FIG. 8C is displayed on the display unit 407 for the power transmission device 300, the power transmission coil excitation unit 306 is started through the power transmission operation unit 307 so as to start excitation at an amplitude and frequency suitable for charging. An instruction is manually issued to the power transmission control unit 305.

  On the other hand, as a result of the determination in step S1507, if it is determined that sufficient magnetic force supply is not obtained, the process returns to step S1503, and the alignment sequence process is subsequently repeated.

  As described above, when performing non-contact charging according to the embodiment described above, the user can intuitively understand which direction the charging device 400 can be moved to a position suitable for charging in accordance with the instruction of the display unit 407.

  Further, in the present embodiment, the magnetic sensor and the display unit are in the charging device, but conversely, the magnetic sensor 300a and the display unit 300b as shown in FIG. Also good. Even with this configuration, alignment processing can be performed by processing according to the present embodiment.

  In the present embodiment, the distance and direction are calculated based on the detection output differences of the plurality of magnetic sensors. In addition, for example, it can be intuitively understood that even if a single magnetic force sensor and a sensor for detecting the movement of the charging device such as an acceleration detection sensor are combined, it can be moved to a position suitable for charging. It is also possible to make it.

  In the present embodiment, the power transmission device 300 is an installed device and the charging device 400 is a portable device. However, for example, both of the devices can be implemented as a portable device. In this case, both of them may have both power transmission and charging functions. Further, in the present embodiment, the direction / distance calculation processing is performed by the mathematical expression represented by Equation 1, but other appropriate calculation processing may be performed.
