Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a motor control method for controlling a plurality of motors for multi-axis driving.

[Conventional technology]

Conventional motor control methods for multi-axis drives can be broadly divided into methods in which multiple motors are operated one by one and moved to the target position, and methods in which multiple motors are operated simultaneously and moved to the target position. .

In addition, in order to operate multiple motors at the same time to move them to the target position, if the keys for multi-axis drive of multiple switches on the transmitter-side operation switch are pressed at the same time, the transmitter will One is that each individual operation signal for driving is simultaneously output to the receiver, and the other is that the transmitter generates each operation signal corresponding to each combination of key human power for multi-axis drive and outputs it to the receiver. There is.

Hereinafter, a two-axis drive motor control device using a conventional multi-axis drive motor control method will be described.

As a first conventional example, a motor control device that operates two motors for two-axis driving one by one will be described.

This motor control device operates one of the two motors on the receiver side by operating multiple switches on the transmitter side one by one.As shown in Figure 1O, first, The motor for driving in the X-axis direction is operated to move the driven object (not shown) from the origin O to point Q in the direction of the arrow.

Next, the motor for driving in the Y-axis direction is operated to move the driven object from point Q to the target position P in the direction of arrow B.

This motor control device does not output an operation signal and does not operate the motor on the receiver side if two or more keys are pressed simultaneously from a plurality of operation switches on the transmitter side.

As a second conventional example, when the respective keys for X-axis direction drive and Y-axis direction drive of a plurality of switches of the operation button on the transmitter side are pressed at the same time, from the transmitter 21, A motor control device that simultaneously outputs individual operation signals for drive in the Y-axis direction to a receiver will be described.

In this motor control device, when the keys for driving the X-axis direction and the Y-axis direction of the multiple switches on the transmitter-side operation button are input simultaneously, the transmitter allows each key to be manually operated. Output the signals to the receiver simultaneously. Then, the motors for driving in the X-axis direction and the motor in the Y-axis direction on the receiver side operate simultaneously according to the respective operation signals, and as shown in FIG. z) moves diagonally in the direction of arrow C.

In addition, this motor control device protects the motor by stopping the output of operation signals on the transmitter side when multiple switches that operate one motor in opposite directions are pressed at the same time. I'm trying.

As a third conventional example, when the keys for X-axis direction drive and Y-axis direction drive of multiple switches of the operation button on the transmitter side are pressed at the same time, the transmitter A motor control device that generates respective operation signals corresponding to combinations of key manual inputs for driving in the Y-axis direction and outputs them to a receiver will be described.

As an example of this motor control device, an infrared remote control type two-axis drive motor control device 1111 will be described with reference to FIGS. 12 and 13.

FIG. 12 shows the configuration of the oscillation circuit of the transmitter of this infrared remote control.

This transmitter includes a DC power supply 21 and a transmitting integrated circuit IC.

According to the above configuration, the crystal oscillator X + + of the reference frequency oscillation circuit 23, the capacitor C11, and the capacitor C

The reference frequency is divided into a modulation frequency of, for example, about 38 KHz within tt. Then, in order to operate the two motors, a plurality of switches SW□ of the operation switch group 22

When any one of S W e + is pressed, the transmission integrated circuit ICt+ confirms the human power of each key and determines the code of the input key. Furthermore, a transmitting integrated circuit IC

＋ ＋ blinks and the receiver (not shown) is used as an operation signal.
Output to.

An example of this operation signal will be explained based on FIG. 13.

This operation signal has a high level portion T modulated with a rectangular wave having a frequency of approximately 38 KHz. The infrared light emitting diode LED shown in FIG. 12 blinks with this modulated signal of 13 parts shown in FIG. 13. In addition, the suspension period T
The light goes out at the I, T and z parts.

Here, T is defined as 1, T is defined as O, and the combination 1 of this pause period T, , T2 is 1, for example, 1010 or 1.
The operation of each axis of the operation signal is determined by a combination such as 001.

This combination of operation signals is used as a transmission signal channel.

Here, a series of specific operations on the transmitter side of this motor control device will be explained.

First, the transmitter checks the presence or absence of manual keystrokes from the plurality of switches SW□, SwL, , sw, , , SW, of the operation switch group 22. And multiple Sui Nchi S
WNl, S WLl, S WLII, S
When at least one or two keys of the WDI are pressed and each key is pressed manually, the code of the manually pressed key is determined and an operation signal corresponding to the key pressed is output to the receiver.Here, 2. If there is any key manual force, that is, multiple switches S of the operation switch group 22
WNl, S WLI, S Wut, S W
For example, if SW □ and SW, , from There is. Then, after a predetermined period of time has elapsed, confirmation of the presence or absence of key human power is started again, and the above-described operation is repeated.

On the other hand, the receiver determines the operation signal input from the transmitter. When a single key manual operation signal is input, either the X-axis direction drive motor or the X-axis direction drive motor corresponding to the key human power is activated. Also,
When an operation signal corresponding to two simultaneous keys is input manually, it is determined that the operation signal is for both X-axis direction drive and X-axis direction drive, and the motors for X-axis direction drive and X-axis direction drive are operate at the same time. As a result, as in the second conventional example, the driven object moves diagonally in the direction of arrow C from the origin 0 to the target position P, as shown in FIG.

[Problem to be solved by the invention]

According to the first conventional motor control method described above, when controlling a multi-axis motor, there is no choice but to control each axis individually, and two axes cannot be moved at the same time. There was a problem in that it was not possible to move diagonally from point P to the target position.

Further, according to the second conventional motor control method, the problem of the first conventional example can be solved, but in a remote control type motor control device using infrared rays etc., the output of the operation signal is a serial signal output. Therefore, there was a problem in that a plurality of operation signals could not be output at the same time, and as a result, the object to be driven could not be moved diagonally.

According to the third conventional motor control method, the problems of the first and second conventional examples can be solved, but the two-axis motor control method simultaneously controls the two-axis motor separately from the operation signals of the individual operation keys of the operation switch on the transmitter side. An operation signal is required at the time of operation, and the number of channels for the operation signal increases, which increases the length of the transmission signal.

As a result, there is a problem in that the time required to transmit the operation signal for operating the motor becomes longer.

In addition, in cases where the number of combinations of operation signals on the transmitter is limited, the number of operation signals during simultaneous operation cannot be increased, so in such cases, similar to the first conventional example, multiple axis There was a problem in that each axis had to be operated in sequence.

Note that in the second and third conventional examples, when operating two motors at the same time, the power supply capacity for driving a plurality of motors is required to drive two motors. A power supply capacity twice as large as that of the conventional example No. 1 is required. Furthermore, there is a problem in that when three axes are operated simultaneously, three times as much power supply capacity is required. Furthermore, as the power supply capacity increases, the size and weight of the device also increase.

Incidentally, the same problems as those described above also exist with respect to the motor control devices for multi-axis driving of three or more axes in each of the above-mentioned conventional examples.

Therefore, an object of the present invention is to reduce the power supply and capacity for driving the motors when moving a driven object by operating a plurality of motors, and to reduce the number of channels for transmission signals of operation signals. It is an object of the present invention to provide a motor control method capable of moving a driven object in an oblique direction by operating a plurality of motors.

[Means to solve the problem]

In the motor control method for multi-axis drive according to the present invention, when a plurality of switches for operating different motors are simultaneously operated, a plurality of types of code signals corresponding to the operation of each of the plurality of switches are transmitted every predetermined time on the transmitter side. The code signal is sequentially and repeatedly sent to the receiver, and the receiver selectively operates one of the plurality of motors depending on the type of the code signal.

[For production]

According to the configuration of the present invention, when a plurality of switches for operating different motors are simultaneously operated on the transmitter side to drive an object to be driven in a diagonal direction, a plurality of switches corresponding to each operation of the plurality of switches are activated. The different types of code signals are sequentially and repeatedly sent to the receiver at predetermined time intervals. Then, on the receiver side, one of the plurality of motors is selectively operated depending on the type of the code signal. At this time, a plurality of types of code signals are sequentially and repeatedly sent from the transmitter, so that the plurality of motors are operated in a 111-order time division manner.

As a result, the driven object appears to move obliquely to the upper target position.

Further, since any one of the plurality of motors is selectively operated, the capacity of the motor driving power source is sufficient to drive one motor.

Furthermore, when multiple switches that operate different motors are operated simultaneously on the transmitter side to drive an object in a diagonal direction, multiple types of code signals corresponding to the operation of each of the multiple switches are predetermined. Since the signals are sent to the receiver repeatedly in sequence over time, the transmitted signal only requires codes corresponding to each of the multiple switches. There is no need to create one.

Timing pulses as shown in FIGS. 4-) are sequentially applied to the column lines of the switch matrix consisting of swL and sw. and a plurality of switches SW.

By pressing any of sw, sw, swL, sw, timing pulses are sequentially applied to the key human control circuit 10 from the row lines of the switch matrix via the pressed switch. As a result, multiple switches s w, s w, s wu, s w
The key manual control circuit 10 can determine which switch, L, SW, has been pressed, and the priority order of key manual power is determined.

Further, the direction in which the motor M1 is operated to move the driven object consisting of a spotlight is the X-axis, and the direction in which the motor M2 is operated to move the driven object is the Y-axis.

Next, a plurality of switches SW, , S of operation switch group 2
If you press any one of the switches W, SW, and Swe that are compatible with the X-axis drive and X-axis drive, or the combination of the switches for the X-axis drive and the By being
The timing pulses output from the timing generation circuit 9 in the transmitting integrated circuit IC are sent as key manual signals through the pressed switches in the order of the timing pulses in the transmitting integrated circuit ICT. 1 circuit 10.

Then, the key manual control circuit 10 sequentially applies signals as shown in FIG. 4(a) corresponding to each key to the pulse train generation circuit 8 in the order in which the timing pulses are input.

The pulse train generation circuit 8 inputs the output signal output from the key manual control circuit 1O, and applies a code signal as shown in FIG. 5 to the modulation circuit 7.

The modulation circuit 7 receives the code signal corresponding to the key input input from the pulse train generation circuit 8 from the frequency dividing circuit 6, and converts the code signal to approximately 3.
8 to 1 (modulate at the modulation frequency of z, base resistor R8
is applied to transistor Q1 through.

The transistor Q is turned on and off by a code signal modulated with the modulation frequency input from the modulation circuit 7, and causes the infrared light emitting diode LED to blink.

The blinking of this infrared light emitting diode LED is sent as an operation signal from the operation signal sending unit 12 shown in FIG. 9 to the receiver H.

A series of operations of this transmitter I will be explained based on the flowchart shown in the third part.

When the DC power supply 1 is applied to the transmitter I, the transmitter I
starts operating, and the plurality of switches S of operation switch group 2
We return confirmation of the presence or absence of human power from each of S WL, S WU, and S WD (Step S,)
. And a plurality of switches S WD of operation button 2,
One of S WL, S WLl, or S Wo.

Alternatively, if a plurality of keys are pressed and there is a key force, the number of key keys is determined (step S2). Here, if there are three or more key keys, no operation signal is output (step Sl
Then, return to step S again.

If the number of keys is one, a code corresponding to the key is determined (step S3), and a pulse train operation signal corresponding to the key is output (step S4). After waiting for a predetermined period of time (step SS), the process returns to step S1 again to confirm the key force.

Next, when the number of key manpower is two, the code corresponding to each key manpower is determined (step S,).
Keys for human power to operate the motor in the opposite direction (
coaxial) (step S?). here,
If the two key inputs are coaxial (YES), no operation signal is output (step SI, return to step SL).The two key inputs are for X-axis drive and Y-axis drive, respectively. If so, it corresponds to either the X-axis driving code or the Y-axis driving code, which is prioritized depending on the order of timing pulses output from the timing generation circuit 9 in the transmission integrated circuit Icy, that is, the first code. A pulse train operation signal is output (step S8), and a predetermined time t
, after waiting (step S), an operation signal of a pulse train corresponding to the other code, that is, the second code, is output (step 5ho). After waiting for a predetermined period of time (step S), the process returns to step SI.

By repeating the above operation, an operation signal is outputted from the transmitter I to the receiver (2) at predetermined time intervals.

Next, the specific operation of the receiver H will be explained based on FIG. 2.

When the receiver (2) inputs the operation signal from the transmitter (2) through the infrared light receiving element PD, the receiver (2) applies the input operation signal to the amplifier AMP. Then, the operation signal is amplified by the amplifier AMP and applied to the receiving integrated circuit IC. Furthermore, in the order of input operation signals, the receiving integrated circuit IC, the transistor that drives the relay of the motor to be operated, and the transistor Q2~
A drive signal is applied to any one of Q5. When the transistor is turned on, current flows through the coil of the relay connected to this transistor.

Then, the contacts of this relay (contacts Sl l + corresponding to the coils of each relay indicated by broken lines in FIG.
3112, SL++ SL! , 5LI1+SUN or S, 1°SO2) are closed, and the motors M1°M2 operate in the desired direction.

As a result of the above, by repeating the above operations in the order of priority of the operation signals output from the transmitter 1, the two motors operate one after the other in a time-sharing manner, as shown in Fig. 7. Thus, the main driving object appears to move obliquely from the origin O to the destination point P.

Note that since the motors M I and M t are DC motors, for example, the voltage applied to the motor M when the coil of relay R1l shown in FIG. The polarity is opposite to that of the voltage applied to M1. Therefore, the rotation of motor M when the coil of relay RII operates is opposite to that when the coil of relay RL operates.

Here, the states of the output signals of the transmitter I and the receiver (2) will be explained in detail based on FIG.

Now, for example, switch SW of the operation switch of transmitter l
Fig. 6 (a) in which the motor M1 is operated to the right when the motor M1 is pushed.
Assume that an operation signal R as shown in -1) is output from the transmitter 1. Then, the receiver ■ inputs the operation signal, and after a while (time t8 when the reception integrated circuit IC judges the operation signal manually inputted), the reception integrated circuit rc inputs the operation signal to the transistor Q2 as shown in FIG. 6 (a- An output signal as shown in 2) is output at 1° for a certain period of time.

With this output signal, for a certain period of time tl, transistor Q2
turns on, and current flows through the coils of relay R. Then, the contact of relay R closes, and motor M1 operates in the right direction for a certain period of time t1.

Also, switch SW of the transmitter I operation switch.

If the button is kept pressed, an operation signal R as shown in FIG. 6(b-1) is continuously outputted from the transmitter 1. Then, after the receiver ■ inputs the first operation signal, the reception integrated circuit IC judges the operation signal at a time t2, similar to the above.
After that, the receiving integrated circuit rc.

The output signal is output to transistor Q2 for a certain period of time.

Output. Furthermore, by inputting the next operation signal R, the output signal for a certain period of time t1 is repeatedly output. Also, like the previous output signal, this output signal is output after a time t2 during which the input operation signal is determined by the receiving integrated circuit IC. Here, the fixed time period L1 of the output signal of the receiving integrated circuit IC5 is made shorter than the period time t4 of the operation signal to eliminate the time period in which the two output signals overlap.

As a result, an intermittent output signal having a pause time as shown in FIG. 6(b-2) is applied to transistor Q2. Then, as a result of the current flowing in the coil of relay R intermittently for time t3, contacts S□ and Sl□ intermittently flow for time 1. Opens between. As a result, the motor M1 opens and stops for a period of time, and then operates intermittently in the right direction for a period of time L1.

Next, when the X-axis drive switch SWヮ and the X-axis drive switch SWu of the operation switch 2 are pressed at the same time in the transmitter I, the pulse trains are different in the priority order of the key manual power from the transmitter H1 as shown in Fig. 6. Operation signal R as shown in (c-1)
and U are output.

Then, the operation signals R and U are inputted to the receiver ■, the operation signals R and U are discriminated by the receiving integrated circuit IC, and the transistors Q for the X-axis drive and the X-axis drive respectively are
Figure 6 (c-2), (c
As shown in -3), output signals each having a certain period of time t1 are sequentially applied. In this case, as well as when one switch is kept pressed, the fixed time t1 of each output signal of the receiving integrated circuit IC is the period from when the operation signal R is input until when the operation signal U is input. It is made shorter than the cycle time t4. As a result, the composite signal of the respective output signals of the receiving integrated circuit IC corresponding to the operation signals R and U has a pause time t.

Then, the transistors Q, , Q, sequentially operate for a certain period of time t1.
It is turned on for a while and current flows through the coils of relays R+t and Ru. and relays R,,R.

respective contacts S□+SR1 and 5Lll+S
u2 is closed sequentially for time t1. As a result, motor M
1°M2 sequentially, intermittently at time t,
It will operate for 1 hour. Therefore, as shown in FIG. 7, the X-axis drive motor M1 and the X-axis drive motor M
2 are operated in sequence, and the driven object consisting of the spotlight moves apparently upwardly diagonally from the origin 0 to the target position P point.

The motor control 'l'Il device for two-axis drive according to the second embodiment includes, on the transmitter I side, a plurality of switches SWl, SWL, SW, .
When you operate SW, multiple switches SW, SWL at the same time.

The receiver H sequentially repeats multiple types of code signals corresponding to each operation of S W u and S W e at predetermined time intervals.
On the receiver side, two motors M, , M are used depending on the type of code signal output from the transmitter I.

Since one of the two motors is selectively activated, the two motors M+ and Mz are sequentially driven in a time-division manner, so the object to be driven is apparently operated diagonally upward to the target position. Can be done. Further, since either one of the two motors M+ and Mt is selectively operated, the capacity of the motor driving power source 4 is sufficient to drive one motor.

Furthermore, on the transmitter l side, two motors M + ,
A plurality of switches SW, l actuating M t.

When S W L, S W u, S W o are operated simultaneously, multiple switches S WR, S Wt, S
Since multiple types of coat signals corresponding to each operation of Wu and S We are sequentially and repeatedly sent to the receiver ■ at predetermined time intervals, the transmitted signals are sent to multiple switches SW
R, S WL.

Only the codes corresponding to SWu and SWD are required, and there is no need to create separate operation signals corresponding to the human power of the keys of the two switches when they are operated simultaneously. Therefore, the number of transmission signal channels can be reduced.

In this embodiment, an infrared remote control type motor control device for two-axis drive has been described, but a motor control device for multi-axis drive of three or more axes can also be used.

Moreover, other remote control methods other than the infrared remote control method may be used.

Further, it may be used in a multi-axis drive motor control device that does not use remote control.

〔Effect of the invention〕

In the motor control method of the present invention, when a plurality of switches for operating different motors are simultaneously operated, a plurality of types of code signals corresponding to the operation of each of the plurality of switches are sequentially transmitted to the receiver at predetermined time intervals on the transmitter side. On the sending and receiving side,
Since any one of the plurality of motors is selectively activated according to the type of code signal output from the transmitter, the plurality of motors are driven in one time-division manner.

As a result, the object to be driven can be operated obliquely to the target position, although it appears to be upward. In addition, the capacity of the motor drive power supply is sufficient to drive one motor.
Furthermore, in order to drive an object diagonally, the transmission signal only needs to be the code corresponding to each of the multiple switches, and it is necessary to create a combination of operation signals that correspond to the human power of the keys of multiple switches when operated simultaneously. is gone,
The number of transmission signal channels can be reduced.
