FIG. 11 is a block diagram illustrating an overall configuration of a reception antenna adjustment support device according to a second embodiment.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) First Embodiment (1-1) Configuration of Receiving Antenna Adjustment Supporting Apparatus According to This Embodiment In FIG. 1, reference numeral 1 denotes a receiving antenna adjustment assisting apparatus according to the present embodiment as a whole. The receiving antenna adjustment support device 1 is a device that assists an operator in adjusting a resonance frequency of the receiving antenna 2 in a power wave receiving device or a manufacturing factory of the receiving antenna 2. , A transmission antenna 11, a control unit 12, a power measurement unit 13, a voltage measurement unit 14, and a display unit 15.

  Note that each of the transmitting antenna 11 and the receiving antenna 2 is formed of a loop antenna. Further, a trimmer capacitor (not shown) is mounted on the receiving antenna 2, and the operator 3 can change the resonance frequency of the receiving antenna 2 by rotating the knob of the trimmer capacitor.

  The oscillator 10 includes a voltage-controlled transmitter, generates a first AC signal S1 having a frequency and an amplitude specified by a setting instruction COM given from the control unit 12, and transmits the generated first AC signal S1. Output to the antenna 11. The transmitting antenna 11 converts the first AC signal S1 supplied from the oscillator 10 into a power wave S2 and transmits the power wave S2, and also generates a signal in proportion to the amount of power applied to the transmitting antenna 11 by the first AC signal S1. The transmission antenna power observation signal S3 whose level fluctuates is output to the power measurement unit 13.

  The power measurement unit 13 measures the amount of power applied to the transmission antenna 11 at that time based on the transmission antenna power observation signal S3 given from the transmission antenna 11, and outputs the measurement result to the control unit 12.

  On the other hand, the receiving antenna 2 receives the power wave S2 transmitted from the transmitting antenna 11, converts it into a second AC output, and converts the second AC output into a DC output by a built-in rectifier circuit (not shown). To generate operating power for the internal circuit. The DC output of the rectifier circuit is also provided to the voltage measurement unit 14 of the receiving antenna adjustment support device 1 as a rectified output signal S4. Then, the voltage measurement unit 14 measures the voltage value of the rectified output signal S4 given from the reception antenna 2 and outputs the measurement result to the control unit 12.

  The control unit 12 gradually increases or decreases the oscillation frequency of the oscillator 10 by appropriately giving the setting instruction COM to the oscillator 10, and at this time, the power value of the power wave S 2 provided from the power measurement unit 13 and the voltage The current resonance frequency of the receiving antenna 2 is detected based on the voltage value of the rectified output signal S4 output from the rectifying circuit of the receiving antenna 2 given from the measuring unit 14.

  When the detected current resonance frequency of the reception antenna 2 is out of the allowable error range, the control unit 12 sets the resonance frequency of the reception antenna 2 to a preset target frequency (hereinafter, this is referred to as an adjustment target). The operation amount (the number of revolutions R) of the trimmer capacitor of the receiving antenna 2 for approximating the frequency (referred to as frequency) is calculated, and the calculated amount is displayed on the display unit 15 including a liquid crystal display or the like.

  Accordingly, the worker 3 can change the resonance frequency of the receiving antenna 2 toward the adjustment target frequency fr by rotating the knob of the trimmer capacitor of the receiving antenna 2 by the number of rotations R displayed on the display unit 15. it can.

(1-2) Adjustment work support processing FIG. 2 shows a processing procedure of the adjustment work support processing executed by the reception antenna adjustment support apparatus 1 according to the present embodiment. This adjustment work support process is a process for assisting the worker 3 in adjusting the resonance frequency of the receiving antenna 2.

  In this adjustment work, the receiving antenna 2 to be adjusted (hereinafter, referred to as an adjusting receiving antenna 2) is centered on a transmitting antenna 11 for adjustment (hereinafter, referred to as an adjusting transmitting antenna 11). Must be kept on the same axis as the center of, and parallel to the adjustment transmitting antenna 11 and always at a constant distance from the adjusting transmission antenna 11. Therefore, the receiving antenna adjustment assisting apparatus 1 of the present embodiment has an installation jig shown in FIG. 3 in order to quickly and accurately perform the positioning work of the adjustment target receiving antenna 2 with respect to the adjusting transmitting antenna 11. A tool 20 is provided.

  The installation jig 20 is configured such that a first plate 31 on which the adjustment transmitting antenna 11 is fixed and a second plate 32 on which the receiving antenna 2 to be adjusted is placed are parallel to each other via a plurality of columns 33 and have a predetermined distance. It is configured to be connected only at a distance. Then, at the mounting position of the adjustment target reception antenna 2 on the upper surface of the second plate 32, the mounted adjustment target reception antenna 2 can be positioned with the center position aligned with the adjustment transmission antenna 11. A frame 34 having substantially the same inner dimensions and inner shape as the outer dimensions of the receiving antenna 2 to be adjusted is fixedly arranged.

  When starting the adjustment operation of the resonance frequency of the adjustment target receiving antenna 2, the worker 3 (FIG. 1) first fits the adjustment target receiving antenna 2 into the frame 34 of the installation jig 20. Place on the second plate 32. As a result, the receiving antenna 2 to be adjusted is positioned such that the center position of the receiving antenna 2 matches with the transmitting antenna 11 for adjustment fixed on the first plate 31 and is separated from the adjusting transmitting antenna 11 by a certain distance.

  After that, the worker 3 performs a predetermined operation input to the reception antenna adjustment support device 1. Thereby, the adjustment work support processing shown in FIG. 3 by the control unit 12 of the reception antenna adjustment support device 1 is started.

  When the control unit 12 starts the adjustment work support processing, first, in order to measure the frequency characteristic of the reception antenna 2 to be adjusted, the oscillator 10 (FIG. 1) gradually increases or decreases the frequency of the AC signal S1 (FIG. 1). 1), and at this time, the voltage value of the rectified output signal S4 (FIG. 1) output from the rectifier circuit of the receiving antenna 2 to be adjusted is associated with the frequency of the AC signal S1 at that time. , And sequentially store them (SP1).

  Specifically, for example, when the target value of the resonance frequency of the receiving antenna 2 to be adjusted (hereinafter, referred to as an adjustment target frequency fr) is 27.1 [MHz], the control unit 12 sets the setting instruction COM (FIG. 1). Is appropriately transmitted to the oscillator 10 so that the frequency of the AC signal S1 output from the oscillator 10 is within a predetermined range including the adjustment target frequency fr (for example, within a range of 26.9 to 27.3 [MHz]), and the frequency is constant ( For example, the oscillator 10 is controlled so as to sequentially increase or decrease at intervals of 10 [kHz]. Then, the control unit 12 sequentially acquires the voltage value of the rectified output signal measured by the voltage measurement unit 14 (FIG. 1) every time the frequency of the first AC signal S1 is increased or decreased in the above-described frequency increment. , And stores the acquired voltage value in association with the frequency of the first AC signal S1 at that time.

  At this time, the impedance of the adjustment transmitting antenna 11 changes with the change of the frequency of the AC signal S1, and the power of the power wave S2 (FIG. 1) also changes. Therefore, the control unit 12 sends the AC signal to the oscillator 10 in the setting instruction COM so that the amount of power applied to the transmission antenna 11 by the first AC signal S1 measured by the power measurement unit 13 is always constant. The amplitude of S1 is also indicated.

  In the process of step SP1, when the voltage value of the rectified output signal S4 measured by the voltage measurement unit 14 is equal to or smaller than a preset threshold, the reception antenna 2 to be adjusted at that time is a defective product. The control unit 12 may determine that there is.

  Subsequently, based on the voltage value of the rectified output signal S4 at each frequency of the first AC signal S1 acquired in step SP1, the control unit 12 determines the frequency of the first AC signal S1 at which the voltage value becomes the maximum. It is acquired as the current resonance frequency f of the receiving antenna 2 to be adjusted (SP2).

  Next, the control unit 12 sets the current resonance frequency f of the adjustment target receiving antenna 2 acquired in step SP2 to an adjustment error range (for example, adjustment) set in advance with respect to the adjustment target frequency fr of the adjustment target reception antenna 2. It is determined whether the target frequency fr falls within ± 100 [kHz] with respect to 27.1 [MHz] (SP3).

  If a negative result is obtained in this determination, the control unit 12 determines the rotation speed of the trimmer capacitor of the reception antenna 2 to be adjusted, which corresponds to the difference between the resonance frequency f obtained in step SP2 and the adjustment target frequency fr. R is calculated, and the calculated rotation speed R is displayed on the display unit 15 (FIG. 1) (SP4).

Here, in general, the relationship between the resonance frequency f of the reception antenna 2 and the capacitance C of the resonance capacitor in the reception antenna 2 (the capacitance of the entire reception antenna 2) is represented by the following equation, where K is a constant. is there.

  The capacitance C of the resonance capacitor in the receiving antenna 2 is a combined capacitance of a fixed capacitance component and a variable capacitance component by a trimmer capacitor, and a change rate Q of the resonance capacitor per rotation of the trimmer capacitor is represented by an antenna circuit constant, It can be defined by the component characteristics of the trimmer capacitor.

  Therefore, the control unit 12 calculates the current resonance frequency f of the adjustment target receiving antenna 2 acquired in step SP2, the adjustment target frequency fr, and the change rate Q of the resonance capacitor per rotation of the trimmer capacitor of the adjustment target reception antenna 2. The rotation speed R of the trimmer condenser is obtained by the following procedure.

によりを求める。 Specifically, the control unit 12 first determines that the capacitance C of the entire receiving antenna 2 to be adjusted at the current resonance frequency f of the receiving antenna 2 to be adjusted and the resonance frequency of the receiving antenna 2 to be adjusted are the adjustment target frequency fr. The frequency ratio X (= √Cr / √C) to the capacitor capacitance Cr of the entire receiving antenna 2 to be adjusted at the time of

By

により、かかるコンデンサ容量Ｃと、かかるコンデンサ容量Ｃｒとの容量比Ｙ（=C/Cr）を求める。 Subsequently, the control unit 12 uses the frequency ratio X obtained by the equation (2) to calculate the following equation.

Thus, the capacitance ratio Y (= C / Cr) between the capacitor capacitance C and the capacitor capacitance Cr is determined.

により、調整対象受信アンテナ２全体のコンデンサ容量の調整量Ｚ（=(Cr-C)/Cr）を算出する。 Further, the control unit 12 uses the capacity ratio Y obtained by the equation (3) to calculate

Thus, the adjustment amount Z (= (Cr−C) / Cr) of the capacitor capacitance of the entire receiving antenna 2 to be adjusted is calculated.

により、調整対象受信アンテナ２のトリマコンデンサの回転数Ｎを求める。 Further, the control unit 12 uses the adjustment amount Z obtained by equation (4) to calculate

Thus, the rotation speed N of the trimmer capacitor of the receiving antenna 2 to be adjusted is obtained.

  Thereafter, the control unit 12 converts the rotation speed N obtained by the expression (5) into a rotation speed R in 0.5 rotation steps in order to reduce the variation in the rotation accuracy of the trimmer condenser caused by the worker 3. Specifically, for example, the control unit 12 determines that R = 1 when the rotation speed N obtained by the equation (5) is 0.8 to 1.2, and R = 1.5 when the rotation speed N is 1.3 to 1.7. When N is 1.8 to 2.2, R = 2,... Then, the control unit 12 displays on the display unit 15 the rotation speed R thus obtained as the operation amount of the trimmer capacitor.

  Thus, the operator 3 rotates the knob of the trimmer capacitor of the receiving antenna 2 to be adjusted by the same rotation speed as the rotation speed R displayed on the display unit 15. Note that the rotation speed R can be any of a positive value and a negative value. The operator 3 can recognize the rotation direction of the trimmer condenser by the sign of the rotation speed R displayed on the display unit 15.

  Then, the control unit 12 returns to step SP1, and thereafter repeats the processing of steps SP1 to SP4 until a positive result is obtained in step SP3.

  Then, the control unit 12 eventually determines that the current resonance frequency f of the receiving antenna 2 to be adjusted determined in step SP2 converges within the allowable error range set for the adjustment target frequency fr. When it is obtained, the adjustment work support processing ends. Thus, the worker 3 then removes the adjustment target receiving antenna 2 from the installation jig 20. Thus, the adjustment operation for the adjustment target receiving antenna 2 is completed.

(1-3) Effects of the present embodiment As described above, in the receiving antenna adjustment support device 1 of the present embodiment, at the time of adjusting the resonance frequency of the receiving antenna 2, the trimmer capacitor mounted on the receiving antenna 2 The operation amount (the number of rotations R) to be operated is displayed on the display unit 15.

  Then, the worker 3 adjusts the resonance frequency of the reception antenna 2 to be closer to the adjustment target frequency by rotating the knob of the trimmer capacitor of the reception antenna 2 by the number of rotations R displayed on the display unit 15. Can be.

  Therefore, according to the reception antenna adjustment support device 1, it is possible to support the adjustment work so that an operator who does not have specialized technical knowledge can adjust the reception antenna 2 with stable adjustment accuracy.
