The current resonance frequency of the receiving antenna is detected, the operation amount of the frequency adjusting electronic element for bringing the current resonance frequency of the detected receiving antenna closer to the target frequency is calculated, and the calculation result is displayed on the display unit. Changed to display.

Further, in the present invention, in the control method of the adjustment support device that supports the adjustment work of adjusting the resonance frequency of the receiving antenna whose resonance frequency can be adjusted by operating the mounted frequency adjustment electronic element, the adjustment support is performed.

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

(1) First Embodiment (1-1) Configuration of the Receiving Antenna Adjustment Support Device According to the Present Embodiment In FIG. 1, 1 shows the receiving antenna adjustment support device according to the present embodiment as a whole. The receiving antenna adjustment support device 1 is a device that assists a worker in adjusting the resonance frequency of the receiving antenna 2 in, for example, a power wave receiving device or a manufacturing plant of the receiving antenna 2, and is an oscillator 10. , A transmitting antenna 11, a control unit 12, a power measurement unit 13, a voltage measurement unit 14, and a display unit 15.

Both the transmitting antenna 11 and the receiving antenna 2 are composed of loop antennas. Further, the receiving antenna 2 is equipped with a trimmer capacitor (not shown), and the worker 3 can change the resonance frequency of the receiving antenna 2 by rotating the knob of the trimmer capacitor.

The oscillator 10 is composed of a voltage control transmitter and the like, 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. Further, the transmitting antenna 11 converts the first AC signal S1 given from the oscillator 10 into a power wave S2 and transmits it, and at the same time, signals 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 and converts it into a second AC output, and also outputs the second AC output to a DC output by a built-in rectifier circuit (not shown). The operating power of the internal circuit is generated by converting to. Further, the DC output of the rectifier circuit is also given to the voltage measuring unit 14 of the receiving antenna adjustment support device 1 as the rectified output signal S4. Then, the voltage measuring unit 14 measures the voltage value of the rectified output signal S4 given from the receiving antenna 2, and outputs the measurement result to the control unit 12.

The control unit 12 gradually raises or lowers the oscillation frequency of the oscillator 10 by appropriately giving the above-mentioned setting instruction COM to the oscillator 10, and at this time, the power value and voltage of the power wave S2 given from the power measurement unit 13. 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 by the measuring unit 14.

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

As a result, 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. can.

(1-2) Adjustment work support process FIG. 2 shows a processing procedure of the adjustment work support process executed by the receiving antenna adjustment support device 1 of the present embodiment. This adjustment work support process is a process for supporting the adjustment work of the resonance frequency of the receiving antenna 2 by the worker 3.

In the adjustment work, the receiving antenna 2 to be adjusted (hereinafter, this is referred to as the adjusting receiving antenna 2) is centered on the adjusting transmitting antenna 11 (hereinafter, this is referred to as the adjusting transmitting antenna 11). It is necessary to keep the antenna on the same axis as the center of the antenna, parallel to the adjusting transmitting antenna 11, and always separated from the adjusting transmitting antenna 11 by a certain distance. Therefore, the receiving antenna adjustment support device 1 of the present embodiment is installed as shown in FIG. 3 in order to enable the positioning work of the receiving antenna 2 to be adjusted with respect to the adjusting transmitting antenna 11 to be performed quickly and accurately. It is equipped with a tool 20.

In this installation jig 20, the first plate 31 on which the adjustment transmitting antenna 11 is fixed and the second plate 32 on which the adjustment target receiving antenna 2 is mounted are parallel and at a predetermined distance via a plurality of columns 33. It is configured by being connected only apart. Then, at the mounting position of the adjusting target receiving antenna 2 on the upper surface of the second plate 32, the mounted adjusting target receiving antenna 2 can be positioned in a state of being centered with respect to the adjusting transmitting antenna 11. A frame body 34 having substantially the same inner size and inner shape as the outer size of the receiving antenna 2 to be adjusted is fixedly arranged.

Then, when the worker 3 (FIG. 1) starts the adjustment work 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 it on the second plate 32. As a result, the receiving antenna 2 to be adjusted is positioned so that the center position of the receiving antenna 2 to be adjusted coincides with the adjusting transmitting antenna 11 fixed on the first plate 31 and is separated by a certain distance.

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

Then, when the control unit 12 starts this adjustment work support process, first, in order to measure the frequency characteristics of the adjustment target receiving antenna 2, the oscillator 10 (the oscillator 10) gradually raises or lowers the frequency of the AC signal S1 (FIG. 1). FIG. 1) is controlled, and the voltage value of the rectified output signal S4 (FIG. 1) output from the rectifying circuit of the receiving antenna 2 to be adjusted at this time is associated with the frequency of the AC signal S1 at that time and is set at a constant time interval. And store them in sequence (SP1).

Specifically, when the target value of the resonance frequency of the adjustment target receiving antenna 2 (hereinafter, this is referred to as the 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 (for example, within the range of 26.9 to 27.3 [MHz]) including the adjustment target frequency fr (for example, within a range of 26.9 to 27.3 [MHz]). For example, the oscillator 10 is controlled so as to gradually increase or decrease in increments 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) at each time the frequency of the first AC signal S1 is increased or decreased in the frequency increments described above. , The acquired voltage value is stored in association with the frequency of the first AC signal S1 at that time.

At this time, the impedance of the adjusting transmission antenna 11 changes with the change in 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 an AC signal to the oscillator 10 in the above-mentioned 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.

If the voltage value of the rectified output signal S4 measured by the voltage measuring unit 14 is equal to or less than a preset threshold value in the process of step SP1, the receiving antenna 2 to be adjusted at that time is defective. The control unit 12 may determine that there is.

Subsequently, the control unit 12 sets the frequency of the first AC signal S1 at which the voltage value becomes maximum based on the voltage value of the rectified output signal S4 at each frequency of the first AC signal S1 acquired in step SP1. 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 a preset tolerance range (for example, adjustment) with respect to the adjustment target frequency fr of the adjustment target receiving antenna 2. It is determined whether or not the target frequency fr is within ± 100 [kHz] with respect to 27.1 [MHz] (SP3).

When the control unit 12 obtains a negative result in this determination, the control unit 12 rotates the trimmer capacitor of the receiving antenna 2 to be adjusted, which corresponds to the difference between the resonance frequency f acquired 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 resonance frequency f of the receiving antenna 2 and the capacitance of the resonance capacitor (capacitor capacitance of the entire receiving antenna 2) C in the receiving antenna 2 are related to the following equation, where K is a constant. be.

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

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

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

To ask for.

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 Eq. (2) to use the following equation.

The capacity ratio Y (= C / Cr) of the capacitor capacity C and the capacitor capacity Cr is obtained.

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 capacitance ratio Y obtained by Eq. (3) and uses the following equation.

Therefore, the adjustment amount Z (= (Cr-C) / Cr) of the capacitor capacity 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 the equation (4) and uses the following equation.

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

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

Thus, the worker 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. The rotation speed R can be either a positive value or a negative value. The worker 3 can recognize the rotation direction of the trimmer capacitor by the sign of the rotation speed R displayed on the display unit 15.

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

Then, the control unit 12 eventually converges the current resonance frequency f of the adjustment target receiving antenna 2 obtained in step SP2 within the tolerance range set for the adjustment target frequency fr, so that a positive result is obtained in step SP3. When it is obtained, this adjustment work support process is terminated. Thus, the worker 3 then removes the adjustment target receiving antenna 2 from the installation jig 20. This completes the adjustment work for the receiving antenna 2 to be adjusted.

On the other hand, the operation amount (rotation number R) to be operated is displayed on the display unit 15.

Then, the worker 3 adjusts the resonance frequency of the receiving antenna 2 to approach the adjustment target frequency 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. Can be done.
