[0011] Each embodiment will be described below with reference to the drawings. In all drawings, the same or corresponding components are denoted by the same reference numerals, and common descriptions will be omitted.

[0012] First Embodiment Hereinafter, the position adjustment device according to the present disclosure will be described with reference to the drawings. FIG. 1 is a first diagram showing an overview of a radiated emission test system including a position adjustment device. FIG. 1 shows a radiated emission test system that performs radiated emission measurements for EMC (Electromagnetic Compatibility). Hereinafter, the radiated emission test system will be referred to as system 100. System 100 includes a position adjustment device 1, a target device 2, a base 3, a turntable 4, a moving mechanism 5, and a scanner 6. System 100 is installed in an anechoic chamber, and scanner 6 is installed near the ceiling of the anechoic chamber.

[0013] FIG. 2 is a top view of the base on which the target device is placed. The target device 2 may include multiple devices such as an electronic device under test (EUT) that emits electromagnetic waves and associated equipment (AE) for testing. The target device 2 disclosed herein includes three target devices 2. As an example, the target device 2 may be a PC main unit, a monitor, a peripheral device connected to the PC main unit, etc.

[0014] FIG. 3 shows the state of the target device after the position adjustment. Based on the positions of multiple target devices 2, the position adjustment device 1 identifies the center position of an imaginary outer circumference circle C1 that contains the target devices 2, and calculates movement information to align this center position with a predetermined position. As an example, the center position O of a turntable 4 is set to a predetermined position in advance, and the position adjustment device 1 controls the center position O to align with the center position of the imaginary outer circumference circle C1. The target devices 2 are placed on a pedestal 3, which may be rotatable by the turntable. The pedestal 3 is equipped with a movement mechanism 5, which will be described below. A scanner 6 scans the pedestal 3 on which the target devices 2 are placed. The scanner 6 may also be a camera that photographs the pedestal 3 on which the target devices 2 are placed.

[0015] FIG. 4 is a second diagram showing an overview of a radiated emissions test system. As shown in FIG. 4, the system 100 includes an antenna 7. The system 100 receives electromagnetic noise emitted by an electronic device among the target devices 2 using the antenna 7 and measures the intensity of the electromagnetic noise. When performing radiated emissions measurements, the system 100 must align the center of an imaginary outer circle that includes three target devices 2, including the target electronic device and auxiliary devices, with a predetermined position, such as the center O of the turntable 4. The turntable 4 is predetermined based on the direction and position of the antenna 7. As shown in FIG. 2, the base 3 placed on the turntable 4 can be moved in the front-to-back direction about an axis that is the axis between the antenna and the turntable center O, and in the left-to-right direction perpendicular to the axis. In the present disclosure, the position adjustment device 1 can move the base 3 in the front-to-back direction using the movement mechanism 5 of the base 3. In the present disclosure, the left-to-right direction can be moved manually. In another embodiment of the system 100, the position adjustment device 1 may be able to freely move the base 3 in the front-to-back and left-to-right directions.

[0016] FIG. 5 is a diagram showing the appearance of the position adjustment device. As shown in FIG. 5 , the position adjustment device 1 is provided with a display 31, a scan execution switch 32, an adjustment start switch 33, a movement stop switch 34, a first movement distance display unit 35, and a second movement distance display unit 36. The display 31 displays an image scanned by the scanner 6, including the target device 2. The scan execution switch 32 is a switch that instructs the scanner 6 to start operation. The adjustment start switch 33 is a switch that operates the movement mechanism 5 of the base 3 to control the position of the base 3, including the target device 2. The movement stop switch 34 is a switch that stops the operation of the movement mechanism 5. The first movement distance display unit 35 is the distance in the forward / backward direction calculated by the position adjustment device 1. As an example, the distance in the forward / backward direction is displayed as a positive or negative distance, with a positive value indicating the distance moved forward toward the antenna 7 and a negative value indicating the distance moved backward away from the antenna 7. The second movement distance display unit 36 ​​is the distance in the left / right direction calculated by the position adjustment device 1. As an example, the distance in the left / right direction is displayed as a positive or negative distance, with a positive value indicating the distance moved rightward toward the antenna 7 and a negative value indicating the distance moved leftward toward the antenna 7.

[0017] FIG. 6 is a diagram showing the relationship between the target device, the base, and the turntable. As shown in Fig. 6, the base 3 on which the target device 2 is placed may be equipped with wheels 31. Furthermore, as shown in Fig. 4, the turntable 4 may be provided with guide rails 41. The movement mechanism 5 may move the base 3 along the guide rails 41 based on control from the position adjustment device 1. Alternatively, the position adjustment device 1 may control the movement of the base 3 by rotating the wheels 31.

[0018] FIG. 7 is a diagram showing the relationship between the movement mechanism and the guide rails. As shown in Fig. 7, the movement mechanism may move linearly along a guide rail. For example, in the present disclosure, the movement mechanism 5 may move the base 3 along the guide rail so that the target device 2 moves back and forth toward the antenna. In another example, a guide rail may be provided in the left-right direction, and the base 3 may be moved left and right.

[0019] FIG. 8 is a diagram showing an example of movement information. Based on the positions of multiple target devices 2, the position adjustment device 1 calculates an imaginary outer periphery circle C1 that is tangent to the inside of the target devices 2. The position adjustment device 1 calculates movement information for positioning the center Co of the imaginary outer periphery circle C1 at a position that is predetermined based on the orientation (or direction of directivity) and position of the antenna 7, such as the center O of the turntable 4. In the present disclosure, the movement information is a forward / backward movement distance d1 and a left / right movement distance d2. If the predetermined position is the center O of the turntable 4, the position adjustment device 1 moves the base 3 to align the center Co of the imaginary outer periphery circle C1 with the center O of the turntable 4. Alternatively, if the predetermined position is another position O2, the position adjustment device 1 may calculate movement information for moving the imaginary outer periphery circle C1 to position O2 and move the turntable 4 so that the imaginary outer periphery circle C1 aligns with position O2.

[0020] FIG. 9 is a hardware configuration diagram of the position adjustment device. As shown in FIG. 9, the position adjustment device 1 is a computer equipped with various hardware components such as a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a storage device 104, a communication module 105, and a sensor 106.

[0021] FIG. 10 is a functional block diagram of the position adjustment device. 10, the position adjustment device 1 performs the functions of an image acquisition unit 11, a position calculation unit 12, a position acquisition unit 13, a center position identification unit 14, a movement information calculation unit 15, a movement control unit 16, and a test start unit 17. The CPU 101 of the position adjustment device 1 may execute a predetermined program to perform the functions of each processing unit shown in FIG.

[0022] The image acquisition unit 11 acquires an image including the target device 2 from a scanner 6 installed above the target device 2 . The position calculation unit 12 calculates the positions of a plurality of target devices. The location acquisition unit 13 acquires the locations of a plurality of target devices. The center position specifying unit 14 specifies the center position of a virtual outer circle that includes a plurality of target devices 2 inside the circle. The movement information calculation unit 15 calculates movement information for aligning the center position of the virtual outer circle with a predetermined position. The movement information indicates, for example, a forward / backward movement distance and a left / right movement distance. The movement control unit 16 controls the movement of the position of the base 3 on which each of the plurality of target devices 2 is placed so that the center position of the virtual outer circumferential circle coincides with a predetermined position based on the movement information. After detecting the completion of the movement control, the test start unit 17 outputs a start signal for the radiated emission test to the analyzer for the antenna received signal and the target device 2.

[0023] In another disclosure, a position adjustment device 1 having functions corresponding to the above-mentioned processing units may be configured by connecting multiple devices 1 via a communication network. In this case, each device constituting the position adjustment device 1 may execute a predetermined program to perform each function similar to that of the position adjustment device 1 of the present disclosure.

[0024] FIG. 11 is a diagram showing an outline of the processing of the radiated emission test system. FIG. 12 is a diagram showing a processing flow of the position adjustment device. Next, the details of the processing of the position adjustment device 1 will be explained step by step. A measurer who is to measure the radiated emissions of the target device 2 places the target device 2, including the test target device and auxiliary equipment, on the test pedestal 3. The measurer then presses the scan execution switch 32 of the position adjustment device 1. The movement control unit 16 detects that the scan execution switch 32 has been pressed (step S101). The movement control unit 16 outputs a control start signal to the scanner 6. Based on the control start signal, the scanner 6 captures an image of the area of ​​the pedestal 3 including the target device 2 (FIG. 11, S1). The scanner 6 transmits a scanned image of the pedestal 3 to the position adjustment device 1 (FIG. 11, S2).

[0025] The image acquisition unit 11 of the position adjustment device 1 acquires a scanned image from the scanner 6 (step S102). The scanned image may be an image showing a two-dimensional plane including the base 3 in a predetermined three-dimensional space. The image acquisition unit 11 outputs the scanned image to the position calculation unit 12. The position calculation unit 12 detects the range within the image of multiple target devices 2 included in the scanned image by pattern recognition of known target devices 2 (step S103). The position calculation unit 12 identifies the in-image coordinates of the contours of the multiple target devices 2 in the image detected by pattern recognition (step S104). The in-image coordinates may be coordinates within the scanned image based on a predetermined position such as the upper left. The position calculation unit 12 outputs the in-image coordinates of the contours of the multiple target devices 2 to the position acquisition unit 13. Note that the function of the position calculation unit 12 may be provided in the scanner 6 or another information processing device, and the position acquisition unit 13 may acquire the in-image coordinates of the contours of the multiple target devices 2 from the scanner 6 or another information processing device. The position acquisition unit 13 outputs the coordinates of the contours of the plurality of target devices 2 within the image to the center position identification unit 14 .

[0026] Based on the coordinates of the contours of the multiple target devices 2 in the image, the center position identifying unit 14 calculates the smallest imaginary outer circle that is tangent to any two or more of those coordinates and includes the target devices 2 inside (step S105). The center position identifying unit 14 also calculates the center coordinates of the imaginary outer circle in the image (step S106). The center position identifying unit 14 calculates three-dimensional space coordinates corresponding to the center coordinates in the image of the imaginary outer circle based on a predetermined conversion formula between the coordinate system in the scanned image and the coordinate system in real space. The center position identifying unit 14 outputs the three-dimensional space coordinates corresponding to the center coordinates in the image of the imaginary outer circle to the movement information calculating unit 15.

[0027] The movement information calculation unit 15 acquires from a storage unit or the like the three-dimensional coordinates of a predetermined position that is set in advance based on the position, orientation, etc. of the antenna. The movement information calculation unit 15 calculates a forward / backward movement distance d1 and a left / right movement distance d2 for planar movement to align the three-dimensional spatial coordinates corresponding to the center coordinates within the image of the virtual outer circle with the three-dimensional coordinates of the predetermined position (step S107). The movement information calculation unit 15 outputs movement information including the forward / backward movement distance d1 and the left / right movement distance d2 to the movement control unit 16. The movement information calculation unit 15 displays the forward / backward movement distance d1 of the movement information on the first movement distance display unit 35 (step S108). The movement information calculation unit 15 displays the left / right movement distance d2 of the movement information on the second movement distance display unit 36 ​​(step S109). After checking the forward / backward movement distance d1 and the left / right movement distance d2, the measurer presses the adjustment start switch 33. The measurer's pressing of the adjustment start switch 33 is an example of an instruction to start position adjustment. The movement information calculation unit 15 detects that the adjustment start switch 33 has been pressed (step S110). The movement information calculation unit 15 outputs the forward / backward movement distance d1, which is movement information, to the movement control unit 16. The movement information calculation unit 15 may further output the left / right movement distance d2, which is movement information, to the movement control unit 16.

[0028] The movement control unit 16 outputs the acquired forward / backward movement distance d1 to the movement mechanism 5 (FIG. 11, S3) and controls the base 3 to move in the forward / backward direction (step S111). The movement mechanism 5 moves the base 3 based on the acquired forward / backward movement distance d1 (FIG. 11, S4). This causes the center of the virtual outer circle in the image to coincide with the forward / backward position of the predetermined position to which the center coordinates should be aligned. The movement control unit 16 detects when the measurer presses the movement stop switch 34. In this case, the movement control unit 16 may output a stop signal to the movement mechanism 5 to stop the movement operation.

[0029] If the movement mechanism 5 cannot move in the left-right direction, the measurer then adjusts the left-right direction of the pedestal 3 based on the left-right movement distance d2. As a result, the center of the virtual outer circle in the image coincides with the predetermined position to which the center coordinate should be adjusted. Alternatively, if the left-right direction has already been adjusted, the movement control unit 16 can control the movement of the pedestal 3 in the front-back direction. Note that the movement mechanism 5 may be a mechanism that can move the pedestal 3 in the left-right direction. In this case, the movement control unit 16 outputs the front-back movement distance d1 to the movement mechanism 5, and then outputs the acquired left-right movement distance d2 to the movement mechanism 5 to control the movement of the pedestal 3 in the left-right direction. The movement mechanism 5 moves the pedestal 3 based on the acquired front-back movement distance d1.

[0030] When the movement mechanism 5 completes the movement of the base 3 based on the forward / backward movement distance d1 and the left / right movement distance d2, it transmits a control completion signal of the movement mechanism 5 to the position adjustment device 1. The test initiation unit 17 of the position adjustment device 1 acquires the completion signal (step S112). After detecting the completion signal, the test initiation unit 17 outputs a start signal for the radiated emission test to the target device 2 and the noise signal measurement device (step S113). This causes the electronic device of the target device 2 to operate, and the measurement device measures the electromagnetic noise emitted from the electronic device via the antenna 7.

[0031] According to the above process, simply by placing the target device 2, such as an electronic device or auxiliary device to be measured, on the pedestal 3, it is possible to easily align the center of the imaginary outer circle including the target device 2 with a predetermined position, such as the center of the turntable. As a result, it is possible to obtain test results that meet the requirements of the radiated emission test standard and are highly reproducible.

[0032] In the above example, the position adjustment device 1 is communicatively connected to the scanner 6 and the moving mechanism 5 via a wire. However, the position adjustment device 1 may be communicatively connected to the scanner 6 and the moving mechanism 5 via a wireless connection. In this case, the scanner 6, the moving mechanism 5, and the position adjustment device 1 each have a wireless communication unit.

[0033] In the above example, the position adjustment device 1 calculated the forward / backward movement distance d1 and the left / right movement distance d2 as movement information. However, the position adjustment device 1 may output the three-dimensional coordinates corresponding to the center position of the imaginary outer circumference circle of the scanned image name and the three-dimensional coordinates of a predetermined position to the movement mechanism 5, and the movement mechanism 5 may calculate a movement path based on the three-dimensional coordinates corresponding to the center position of the imaginary outer circumference circle and the three-dimensional coordinates of the predetermined position, and control the movement mechanism 5 so that the center position of the imaginary outer circumference circle moves to the predetermined position. Alternatively, the wheels of the base 3 may be operated based on the control of the movement mechanism 5, so that the center position of the imaginary outer circumference circle moves to the predetermined position.

[0034] In related technology, the target device 2 is placed on the pedestal 3, and the virtual outer circumference and its center are roughly estimated visually in one's mind, and the test table is then manually moved to align the center of the imagined virtual outer circumference with a predetermined position such as the center of a turntable. This made it difficult to align the position accurately, but this technology can solve this problem.

[0035] FIG. 13 is a diagram showing another configuration of the position adjustment device. FIG. 14 is a diagram showing another processing flow of the position adjustment device. The position adjustment device 1 may include at least a position acquisition unit 13, a center position identification unit 14, and a movement information calculation unit 15. The location acquisition unit 13 acquires the locations of a plurality of target devices (step S301). The center position identifying unit 14 identifies the center position of a virtual circle that includes a plurality of target devices inside the circle (step S302). The movement information calculation unit 15 calculates movement information for adjusting the center position to a predetermined position (step S303).
