Description

  The present invention relates to a measuring apparatus that measures a measured quantity used for evaluating a non-contact power feeding apparatus.

  As this type of measurement apparatus, a test apparatus disclosed in Non-Patent Document 1 below is known. This test apparatus is a test apparatus for evaluating a non-contact power feeding device, and the first coil (Primary Coil) on the supply side and the second coil (Secondary Coil) on the power receiving side of the non-contact power feeding device are opposed to each other. In this state, the power is supplied from the first coil and the power received by the second coil can be measured. In this case, the efficiency and the like of the non-contact power feeding apparatus is evaluated by changing the position and orientation of each coil and measuring the power described above for each state of the position and orientation. For this reason, this test apparatus includes a positioning mechanism and can change the position and posture of each coil. Specifically, in the positioning mechanism of this test apparatus, the support portion that supports the first coil is configured to be movable in the XY direction, and in the rotation direction (θ direction) about an axis perpendicular to the XY plane. It is configured to be rotatable. In addition, the support portion that supports the second coil is configured to be movable in the Z direction.

  However, the above-described conventional test apparatus has the following problems to be improved. That is, in this test apparatus, the positions and postures of the first coil and the second coil can be changed by the positioning mechanism. In this case, in the test apparatus described above, the positions and postures of the coils are changed by moving the support portions that support the coils in the XYZθ directions manually or by the driving force of the motor. On the other hand, in order to accurately evaluate the efficiency and the like of the non-contact power feeding device, it is preferable to obtain a large number of measured values by changing the position and posture of each coil as much as possible. However, in the above-described test apparatus, each support portion that supports each coil is moved in the XYZθ direction manually or by the driving force of the motor to change the position and posture of each coil. It is necessary to manually measure the position of each coil using a measuring instrument such as a measure and to record the position and the measured value in association with each other. For this reason, this test apparatus has a problem that it is difficult to improve measurement efficiency. In addition, since the position of each coil is manually measured in this test apparatus, it is difficult to specify the exact position. As a result, the accuracy of the data (measurement accuracy) associated with the coil position and the measured value is reduced. There is also a problem that improvement is difficult.

It is configured to be able to. Specifically, as illustrated in FIG. 2, the holding device 2 includes a supply side holding unit 21, a power receiving side holding unit 22, a moving mechanism 23, and a frame 24. In this case, the supply-side coil 101 is an example of a supply-side electrode, and is formed by winding a conductive wire in a coil shape. The power-receiving side coil 102 is an example of a power-receiving side electrode, and the conductive wire is wound in a coil shape. However, depending on the type (power feeding method) of the non-contact power feeding device, a supply side electrode and a power receiving side electrode formed in a plate shape with a conductive material may be employed.

Specifically, the supply-side holding unit 21 includes a table on which the supply-side coil 101 can be placed, and a fixture (not shown) that fixes the supply-side coil 101 placed on the table as necessary. Has been. In this case, in order to reduce the influence on the magnetic field generated by the supply-side coil 101, a material having a small relative permeability (permeability) and a relative permittivity (dielectric constant) is used as the material constituting the supply-side holding unit 21. Is preferred. Specifically, a resin (for example, an amorphous resin such as polycarbonate, polystyrene, or ABS resin) can be used. Further, when using a metal in consideration of ensuring rigidity and manufacturing efficiency, it is preferable to use aluminum having a relatively low relative permeability and relative permittivity. Further, as shown in FIG. 2, the supply-side holding unit 21 is fixed on a rotary table 32ψ, which will be described later, in the moving mechanism 23 and is moved by the moving mechanism 23. In the drawing, in order to facilitate understanding of the configuration of the moving mechanism 23, the supply side holding portion 21 is illustrated in a state of being separated from the rotary table 32ψ.

  The power receiving side holding unit 22 is configured to be able to hold the power receiving side coil 102 of the non-contact power feeding device. Specifically, the power receiving side holding portion 22 includes a board on which the power receiving side coil 102 is disposed on the lower surface, and a fixture such as a clamp for fixing the power receiving side coil 102 disposed on the board as necessary. Has been. In this case, it is preferable to use a material having a small relative permeability (permeability) and a relative permittivity (dielectric constant) as in the case of the supply side holding unit 21 for the material constituting the power receiving side holding unit 22. Resin similar to the material which comprises the side holding | maintenance part 21 can be used. In addition, when metal is used in consideration of securing rigidity and manufacturing efficiency, it is preferable to use aluminum. Moreover, the power receiving side holding | maintenance part 22 is being fixed to the flame | frame 24, as shown in FIG.

  The moving mechanism 23 moves the supply-side holding unit 21 in six axial directions (XYZ direction and φψθ direction) according to the control of the control unit 8. Specifically, as shown in FIG. 2, the moving mechanism 23 has three movements that can move in the X direction, the Y direction, and the Z direction (three moving directions), which are three axial directions among the six axial directions. Tables 31x, 31y, and 31z (hereinafter also referred to as “movement table 31” when not distinguished) are provided. Further, as shown in the figure, the moving mechanism 23 includes the φ direction (rotation direction centered on the X direction axis) and the ψ direction (Y direction axis) which are the other three axis directions of the six axis directions. Three rotation tables 32φ, 32ψ, 32θ that can be moved in the rotation direction about the center) and θ direction (the rotation direction about the axis in the Z direction) (hereinafter also referred to as “rotation table 32” if not distinguished). It is configured with. In this case, as shown in the figure, the supply side holding part 21 is fixed to the upper surface of the rotary table 32ψ.

  The moving mechanism 23 includes an actuator (not shown) that drives each moving table 31 and each rotating table 32 under the control of the control unit 8. As the actuator, various actuators such as an electric actuator (motor), an air cylinder, a hydraulic cylinder, a linear actuator, and a piezoelectric actuator can be used.

  In this case, the position of the supply-side coil 101 held by the supply-side holding unit 21 is changed (changed) by the movement of the supply-side holding unit 21 in the XYZ directions by each moving table 31, and the supply by each rotary table 32 is performed. The posture of the supply-side coil 101 held by the supply-side holding unit 21 is changed (changed) by the movement of the side holding unit 21 in the φψθ direction.

  The output unit 3 outputs electric power supplied via the supply-side coil 101 of the non-contact power feeding device according to the control of the control unit 8. In this case, the output unit 3 outputs power in a state where the voltage value is maintained at the specified value (state where the current value varies), and a state where the current value is maintained at the specified value (where the voltage value varies) Output mode in which the power is output in the state) and the output mode in which the power value is maintained at the specified value (a state in which the voltage value and the current value fluctuate) and the output mode in which the power is output to the operation unit 5 The power can be supplied in the mode selected by the operation.

  The measurement unit 4 is in a state where power is supplied via the supply side coil 101 of the non-contact power feeding device (in a state where power is output from the output unit 3 to the supply side coil 101) according to the control of the control unit 8. The amount to be measured used for the evaluation of the non-contact power feeding device is measured. In this case, the measurement unit 4 measures the ratio (power supply efficiency) of the power received by the power receiving side coil 102 with respect to the power supplied from the supply side coil 101 of the non-contact power supply apparatus as a measured amount.

  The operation unit 5 includes, for example, a keyboard and a pointing device, and is used when performing various operations related to measurement. Specifically, the operation unit 5 is used when a measurement start instruction operation or a measurement end instruction operation is performed. The operation unit 5 is used when an operation (designation operation) for designating the position and orientation of the supply side coil 101 held by the supply side holding unit 21 of the holding device 2 is performed. The operation unit 5 is used when performing an operation for designating the position and orientation of the supply-side coil 101 so as to change continuously over time. Further, the operation unit 5 is used when performing an operation for specifying the type of the amount to be measured to be measured by the measurement unit 4 and an operation for selecting the output mode when the holding device 2 outputs power.

  The storage unit 6 stores the amount to be measured measured by the measurement unit 4 under the control of the control unit 8. Under the control of the control unit 8, the display unit 7 displays the contents set (designated) using the operation unit 5, the value of the measured amount measured by the measuring unit 4, the image based on the measured amount, and the like.

  The control unit 8 controls each component constituting the measuring device 1 according to an operation on the operation unit 5. Specifically, the control unit 8 moves the supply side holding unit 21 to the moving mechanism 23, and positions the supply side coil 101 held by the supply side holding unit 21 by the operation on the operation unit 5. A movement process is executed to change the state to the position specified in (1) (hereinafter, this state is also referred to as “specified state”). In addition, the control unit 8 executes a measurement process that causes the measurement unit 4 to measure the amount to be measured when the position and orientation of the supply-side coil 101 are set to the designated state. In addition, the control unit 8 stores the measured amount measured by the measuring unit 4 in the storage unit 6 in association with information indicating the position and orientation of the supply-side coil 101 at the time of measurement.

  Further, when the control unit 8 is designated to continuously change the position and posture of the supply side coil 101 as time passes by an operation on the operation unit 5, the supply side coil 101 is moved in the movement process. The position and orientation of the sensor are continuously changed over time according to the designation, and in the measurement process, the measured amount is continuously measured according to the continuous change of the position and orientation of the supply side coil 101. Let

  Next, a method for measuring an amount to be measured used for evaluating the non-contact power feeding apparatus using the measuring apparatus 1 and an operation of the measuring apparatus 1 at that time will be described with reference to the drawings. First, as an example of a measurement target, an example in which a measurement amount used for evaluation of a non-contact power feeding device used for charging a battery of a household electric appliance will be described.

  First, as shown in FIG. 3, the supply-side coil 101 of the non-contact power feeding device to be inspected is placed on the supply-side holding portion 21 of the holding device 2 and fixed by a fixing tool (not shown). The side coil 101 is held by the supply side holding unit 21. Next, the power receiving side coil 102 is held by the power receiving side holding portion 22 by placing the power receiving side coil 102 of the non-contact power feeding device on the lower surface of the power receiving side holding portion 22 and fixing it with a fixing tool (not shown). In this case, when the supply-side coil 101 is housed in a housing or the like, or the power-receiving coil 102 is housed in an electrical product, the state (the supply-side coil 101 is taken out of the housing) When the non-contact power feeding apparatus is evaluated using the measured amount measured in a state where the power receiving coil 102 is not taken out from the electrical product), the supply coil 101 is held by the supply holding unit 21 together with the housing. Then, the power receiving side coil 102 is held by the power receiving side holding portion 22 together with the electric product.

  Subsequently, various settings are performed by operating the operation unit 5. First, the position at which the supply side coil 101 (for example, the central part of the supply side coil 101) is positioned when measuring the measured amount is designated by XYZ coordinates. Next, the posture of the supply-side coil 101 at that position is designated by inputting angles in the φ direction, the ψ direction, and the θ direction. Thereby, the operation of designating one designated state is completed. In this case, the measuring apparatus 1 can measure the measured amount in the designated state each time one designated state (one position and orientation) is designated, or can designate a plurality of designated states in advance. It is also possible to continuously measure the amount to be measured in each designated state while changing the designated state. In this example, a description will be given below assuming that a plurality of designated states are designated in advance.

  Subsequently, the operation unit 5 is operated to specify the type of the measured amount to be measured by the measurement unit 4 and to select an output mode when the holding device 2 outputs power. In this case, power supply efficiency (ratio of received power to supplied power) is specified as the amount to be measured, and an output mode that outputs power while maintaining the voltage value at the specified value is selected as the output mode. And

  Next, the operation unit 5 is operated to perform a measurement start instruction operation. In response to this, the control unit 8 controls the output unit 3 to start the output of power in the selected output mode. Further, the control unit 8 controls the moving mechanism 23 of the holding device 2 so that the supply side coil 101 supported by the supply side holding unit 21 assumes a specified posture at the position specified as the first specified state. In this way, the supply side holding part 21 is moved in the XYZ direction and the φψθ direction (execution of movement processing).

  Subsequently, the control unit 8 controls the measurement unit 4 when the supply-side coil 101 is in the first designated state, and the power received by the power-receiving-side coil 102 with respect to the power supplied from the supply-side coil 101. The power supply efficiency is measured as the amount to be measured, which is the ratio of (measurement processing execution). Next, the control unit 8 causes the storage unit 6 to store the power supply efficiency in the first designated state measured by the measurement unit 4 in association with information indicating the position and orientation of the supply side coil 101 at the time of measurement.

  Subsequently, the control unit 8 controls the moving mechanism 23 of the holding device 2 so that the supply side coil 101 assumes the specified posture at the position specified as the second specified state. Move. Next, when the supply-side coil 101 is in the second designated state, the control unit 8 controls the measurement unit 4 to measure the power feeding efficiency, and subsequently determines the power feeding efficiency in the second designated state. The information is stored in the storage unit 6 in association with information indicating the position and orientation of the supply side coil 101 at the time of measurement. In the same manner, the control unit 8 controls the holding device 2 and the measurement unit 4 to measure the power supply efficiency in each designated state (execution of the movement process and the measurement process), and to improve the power supply efficiency. The information is stored in the storage unit 6 in association with information indicating the position and orientation of the supply side coil 101 at the time of measurement.

  This completes the measurement of the power supply efficiency as the measured quantity used for the evaluation of the non-contact power supply apparatus. In this case, the power supply efficiency stored in the storage unit 6 is displayed as a list of differences in power supply efficiency depending on the position (the coordinates in the XYZ directions) and the posture (the angle in the φψθ direction) of the supply side coil 101, or displayed as a three-dimensional image. Can be used.

  In the measuring apparatus 1, as described above, the control unit 8 is in a specified state in which the position and orientation of the supply-side coil 101 held by the supply-side holding unit 21 are specified by a designation operation on the operation unit 5. A movement process for moving the supply side holding unit 21 to the movement mechanism 23 is executed, and a measurement process for causing the measurement unit 4 to measure a measurement amount when the position and posture of the supply side coil 101 are in a specified state is executed. . For this reason, in this measuring apparatus 1, compared with the conventional configuration in which the position and the measured value of the supply-side coil 101 measured manually each time the supply-side holding unit 21 is moved, the measurement efficiency and Measurement accuracy can be sufficiently improved.

  Next, an example in which the measurement device 1 is used to measure a measurement amount used for evaluating a non-contact power feeding device used for charging a battery of an electric vehicle 200 (see FIG. 4) as another example of a measurement target. Will be described.

  In this case, when the non-contact power feeding apparatus is evaluated using the measured amount measured in a state where the power receiving side coil 102 is disposed in the electric vehicle and the power receiving side coil 102 is not taken out from the electric vehicle, FIG. As described above, the frame 24 and the power receiving side holding unit 22 of the holding device 2 are removed, and the electric vehicle 200 is positioned above the supply side holding unit 21 using the slope 300. In addition, as shown in the figure, the supply-side coil 101 is held by the supply-side holding portion 21 of the holding device 2.

  Next, the operation unit 5 is operated to specify the position and orientation of the supply-side coil 101 when measuring the amount to be measured. In this case, for example, assuming a usage form of a non-contact power feeding device that feeds power to the traveling electric vehicle 200 via the supply coil 101 fixed to a road or the like, the supply coil 101 and the electric vehicle 200 are assumed. It may be preferable to evaluate the non-contact power feeding apparatus using the measured amount measured in a state where the power receiving side coil 102 arranged in the position is relatively moved. When measuring the amount to be measured used for such evaluation, it is specified that one or both of the position and posture of the supply side coil 101 are continuously changed over time. As an example, an initial value (initial position) of the XYZ coordinates of the supply side coil 101 and initial values (initial postures) of angles in the φ direction, ψ direction, and θ direction are designated, and the Y, Z coordinates of the supply side coil 101 and The X coordinate is designated to change at a constant speed for a specified time (for example, 10 seconds) with the angle in the φφθ direction being constant.

  Subsequently, the operation unit 5 is operated to specify, for example, the power supply efficiency as the type of the amount to be measured to be measured by the measurement unit 4, and as the output mode when the holding device 2 outputs power, for example, the power value. Select the output mode to output while maintaining the specified value. Next, the operation unit 5 is operated to perform an instruction operation to start measurement, and in response thereto, the control unit 8 controls the output unit 3 to start outputting power in the selected output mode. Further, the control unit 8 controls the moving mechanism 23 of the holding device 2 so that the supply-side coil 101 supported by the supply-side holding unit 21 has an initial posture (initial specified state) specified at the specified initial position. ) To move the supply side holding portion 21 in the XYZ direction and the φψθ direction.

  Subsequently, the control unit 8 controls the measurement unit 4 when the supply-side coil 101 is in the initial designated state, and receives the power received by the power-receiving-side coil 102 with respect to the power supplied from the supply-side coil 101. The measurement of the power supply efficiency as the measured quantity that is the ratio of Next, the control unit 8 controls the moving mechanism 23 of the holding device 2 to continuously change the X coordinate (position) of the supply-side coil 101 for a specified time at a speed specified by a specified operation on the operation unit 5. (Execution of move processing). Further, the control unit 8 controls the measurement unit 4 to continuously measure the power supply efficiency in accordance with the continuous change in the position of the supply side coil 101 (execution of the measurement process). In addition, the control unit 8 causes the storage unit 6 to store the power supply efficiency continuously measured by the measurement unit 4 in association with information indicating the position and orientation of the supply side coil 101 at the time of measurement.

  In this case, the speed of change of the X coordinate of the supply side coil 101 (that is, the movement speed of the supply side coil 101 in the X direction) is changed a plurality of times, and movement processing and measurement processing are executed for each speed to supply power. By storing the efficiency, the relationship between the speed of the supply-side coil 101 (that is, the moving speed of the electric vehicle 200) and the power supply efficiency can be known, and the non-contact power supply apparatus can be evaluated from the result.

  As described above, the measuring apparatus 1 includes the operation unit 5 that can perform the designation operation for designating the position and orientation of the supply side coil 101, and the supply side holding unit in the moving mechanism 23 so that the supply side coil 101 is in the designated state. And a control unit 8 that executes a measurement process that causes the measurement unit 4 to measure a measured amount when the supply-side coil 101 is in a designated state. For this reason, according to this measuring apparatus 1, the position and attitude | position of the supply side coil 101 are measured whenever the supply side holding | maintenance part 21 is moved, and the measured position and attitude | position, and a measured value are linked | related and recorded. As a result, the measurement work can be shortened sufficiently, and as a result, the measurement efficiency can be sufficiently improved. Moreover, according to this measuring apparatus 1, since the position and attitude | position of the moved supply side coil 101 are the positions designated beforehand, the supply side coil 101 by measuring the position and attitude | position of the supply side coil 101 manually. Therefore, it is possible to reliably prevent a decrease in the accuracy (measurement accuracy) of data in which the position and orientation are associated with the measurement value, thereby sufficiently improving the measurement accuracy.

  Moreover, according to this measuring apparatus 1, since the moving mechanism 23 is configured to be able to move the supply side holding portion 21 in the six-axis directions, only the supply side coil 101 can be arbitrarily moved without moving the power receiving side coil 102. The position (arbitrary relative position with respect to the power receiving side coil 102) can be positioned in an arbitrary posture (arbitrary relative position with respect to the power receiving side coil 102). For this reason, for example, when measuring a measurement amount used for evaluation of a non-contact power feeding device that is used in a state where the power receiving coil 102 is fixed, the measurement amount is measured in a measurement environment according to an actual usage pattern. be able to.

  Further, in this measuring apparatus 1, the operation unit 5 is configured to enable a designation operation for continuously changing the position of the supply-side coil 101 with time, and the control unit 8 designates the designation operation by the designation operation in the movement process. Accordingly, the position of the supply side coil 101 is continuously changed over time, and the measurement target is continuously measured in accordance with the continuous change of the position of the supply side coil 101 in the measurement process. For this reason, according to this measuring apparatus 1, for example, when the non-contact power feeding apparatus is evaluated from the relationship between the change state of the position of the supply side coil 101 (for example, the moving speed of the supply side coil 101) and the measured amount. It is possible to measure the amount to be measured that can be used effectively in

  The measuring device is not limited to the above configuration. For example, the example in which the moving mechanism 23 that can move the supply-side holding unit 21 in the six-axis direction is described above. However, the moving mechanism 23 that can move in all six-axis directions is not necessarily used, and contactless power feeding It is also possible to employ a moving mechanism 23 that can move the supply side holding portion 21 only in a part of the six axial directions according to the usage form of the apparatus.

  Further, the configuration example in which the moving mechanism 23 moves the supply-side holding unit 21 that holds the supply-side coil 101 of the non-contact power feeding device has been described above. However, the power-receiving side holding unit 22 that holds the power-receiving side coil 102 of the non-contact power feeding device. It is also possible to adopt a configuration in which the moving mechanism 23 moves. Also in this configuration, it is possible to employ a moving mechanism 23 that can move the power receiving side holding portion 22 in the six-axis direction. It is also possible to employ a moving mechanism 23 that can move the side holding portion 22.

  In addition, a configuration in which the moving mechanism 23 moves both the supply side holding unit 21 that holds the supply side coil 101 and the power reception side holding unit 22 that holds the power reception side coil 102 may be employed. In this case, the axial direction in which the supply-side holding unit 21 is moved can be defined as any number of axial directions from one axial direction to six axial directions, and the axial direction in which the power-receiving-side holding unit 22 is moved is also one axis. Any number of axial directions from the direction to the six axial directions can be defined. Further, in the configuration in which the moving mechanism 23 moves both the supply-side holding unit 21 and the power-receiving-side holding unit 22, the supply-side holding unit in the n-axis direction (n is a natural number of 1 or more and 5 or less) among the six axis directions. 21 is moved, and the power receiving side holding part 22 is moved in the m axis direction (m is 6-n) excluding the n axis direction of the six axes (that is, the supply side holding part 21 and the power receiving side holding part 22 are moved). It is also possible to adopt a configuration in which they are moved in the 6-axis direction. With this configuration, both the supply-side holding unit 21 and the power-receiving-side holding unit 22 are moved to position the supply-side coil 101 and the power-receiving-side coil 102 in arbitrary relative positions. The structure of the moving mechanism 23 can be most simplified among various configurations to be performed (a configuration in which the moving directions of the supply-side holding unit 21 and the power-receiving-side holding unit 22 are six or more axial directions).

  Moreover, although the configuration example for measuring the power supply efficiency as the measured amount has been described above, other measured amounts can also be measured. For example, a magnetic field sensor is arranged around the frame 24 of the holding device 2 and the holding device 2, and the magnetic field generated from the supply-side coil 101 can be measured as a measured amount based on a detection value detected by the magnetic field sensor. 4, and the control unit 8 may perform a measurement process that controls the measurement unit 4 to measure a magnetic field when the movement process is executed.
