The angular velocity control of the motor 35 is shared. A dial position command Pc is given to the outer loop, and the controller 43 considers the polarity (rotation direction) and the number of pulses of the two-phase pulse from the encoder 64 and outputs the two-phase pulse from the encoder 64 as shown in FIG. The dial position 8 of the dial tablet 8 is calculated by the integral calculation of. The controller 43
Performs initialization of the dial position P (origin reset) by initializing the integral value at the start of the unlocking operation of the dial lock 8.

The controller 43 compares the calculated dial position P with the dial position command Pc to obtain a position deviation ΔP (= Pc−P), converts the ΔP into an angular velocity command, and performs a gain schedule. Angular velocity command ωc
Ask for. The gain schedule is to rotate the DC motor 35 at a high speed when the rotation position of the DC motor 35 is apart from the target value (when the position deviation ΔP is large), and when the rotation position of the DC motor 35 approaches the target value (position Deviation ΔP
Is provided for rotating the DC motor 35 at a low speed. That is, the controller 43
As shown in (b), the position deviation ΔP is converted into an angular velocity command ωc stepwise according to the magnitude.

The controller 43 calculates the angular velocity ω of the DC motor 35 based on the polarity of the two-phase pulse and the pulse interval T from the encoder 64 as shown in FIG. 3D, that is, as shown in FIG. The angular velocity ω is calculated as ω∝1 / T
Ask for. The controller 43 compares the angular velocity command ωc with the angular velocity ω to obtain an angular velocity deviation Δω, converts the angular velocity deviation Δω into a pulse width modulation (PWM) pulse, and then uses the PWM pulse to generate a transistor or a power MOSFET. The DC motor 35 is driven via an H-bridge circuit (not shown).

The DC motor 35 rotates the dial lock shaft 68 via the clutch mechanism 51 and the reduction gear 67, and the encoder 64 is driven by the DC motor 35 via the clutch mechanism 51 to generate two-phase pulses. By the above servo operation, the dial lock shaft 68 rotates by a predetermined amount following the dial position command Pc. The controller 43 stores the dial number based on the calculated dial position P when registering the dial number, and clears the stored dial number when clearing the dial number. The stored dial number is used in the automatic unlocking sequence and the automatic locking process of the dial lock control program.

FIGS. 5 to 9 show the processing flow of the dial lock control program. FIG. 5 shows the main processing of the dial lock control program. The controller 43 has an automatic mode,
It is determined from the mode signal from the setting switch 62 whether any one of the manual mode, the dial number registration mode, and the dial number clear mode is selected and designated, and the dial number registration mode is selected and designated by the setting switch 62. In this case, a dial number registration process is executed.

When the automatic mode is selected and designated by the setting switch 62, the controller 43 determines the open / closed state of the door 3 based on the detection signal from the door open / close detector 44, and determines whether the door 3 is closed. Then, it is determined whether or not the auto lock is established, that is, whether or not the set time has elapsed since the time when the door 3 was closed. Lock open / close detector 4
5, the open / closed state of the cylinder lock 9 is determined. When the cylinder lock 9 is in the open state, the controller 43 checks whether or not an automatic unlocking permission signal has been input from the automatic unlocking permission input means. Execute the lock sequence.

The controller 43 turns on (valid) the switching means 46 in response to a signal from the switching means 46 when the door 3 is closed (changed from the open state to the closed state) in the judgment of the opening / closing state of the door 3. , Or off (invalid). If the switching means 46 is on (valid), the automatic locking process is executed. The controller 43 executes the automatic locking process if the automatic lock is established (if the set time has elapsed from the time when the door 3 is closed) by judging whether or not the automatic lock is established, and opens and closes the cylinder lock 9. When the cylinder lock 9 is closed according to the state judgment (when the state changes from the open state to the closed state)
To execute the automatic locking process.

Here, there are cases where the door 3 is frequently opened and closed due to the use of the safe 1. At this time, if the dial lock 8 is locked each time, it is necessary to release the dial lock 8 each time, and the operability is extremely reduced. In such a case, when the switching means 46 is turned off, the automatic locking process is not performed when the door 3 is closed (when the door 3 is changed from the open state to the closed state). Thereby, even if the door 3 is closed and the bar 6 is positioned at the lock position, the dial lock 8 is not locked, and the door 3 can be opened and closed only by operating the handle 7.

However, when the door 3 is closed, the dial lock 8
When the locking of the dial lock 8 is not performed, the switching means 46 is turned on and the dial lock 8 is not locked.
To prevent this, when the switching means 46 is turned on, when the door 3 is closed, the controller 43 executes an automatic locking process to lock the dial lock 8 automatically.

When the dial number clear mode is selected and designated by the setting switch 62, the controller 43 executes a dial number clearing process.
The controller 43 does nothing when the manual mode is selected and specified. Therefore, when the manual mode is selected and designated, it is the same as the absence of the control system.

FIG. 6 shows the automatic unlocking sequence. The controller 43 executes the dial number registration process before executing the automatic unlocking sequence, stores the dial number unlocking data P1, P2, P3, and P4 of the dial lock 8, and executes the automatic unlocking sequence. Dial lock 8 before
It is assumed that the zero scale of the dial is aligned with the index line. In other words, if the two conditions that the dial number unlock data P1, P2, P3, and P4 are registered and the dial 0 of the dial lock 8 is aligned with the index line are satisfied, the controller 43 automatically sets The execution of the unlocking sequence becomes possible.

In the automatic unlocking sequence, the controller 43 sends the dial number unlock data P1, P2, P
It is determined whether or not P3 and P4 are registered. If the dial number unlock data P1, P2, P3 and P4 are registered, the dial position P is reset by resetting the origin and the clutch mechanism 51 is connected. Next, the controller 43
Is the stored dial number unlock data P1, P2,

12, P13, P14, P21, P22, P23, P3
1, P32, P41) are calculated.

In this case, as shown in FIG. 7, for example, the controller 43 sets P11 = P1, P12 = P11 + 10
0 (for one rotation of the dial lock shaft 68), P13 = P12 +
100, P14 = P13 + 100, P21 = P2, P2
2 = P21-100, P23 = P22-100, P31
= P3, P32 = P31 + 100, P41 = P4, and dial position commands P11, P12, P13, P1
4, P21, P22, P23, P31, P32, P41
Ask for.

Next, the controller 43 sequentially supplies the dial position commands P11 to P41 to the dial lock control loop to rotate the DC motor 35, and the dial lock shaft 68
