Abstract

PURPOSE:To simplify equipment in structure and reduce the cost of production as well as to make handling operation so easily by making an infrared ray emitting means, emitting a locking signal according to unlocking operation, so as to emit a warning signal in addition. CONSTITUTION:When unlocking operation is performed by an input switch group 2a of an electric lock controller 2 situated in a spot distant from an electric lock 1, a locking signal by infrared rays is emitted out of an infrared ray emitting part 2c. When it is received by an infrared ray receiving part 3b of an electric lock controller 3 adjacently installed in the electric lock 1 and it is confirmed as a specified signal, the electric lock 1 is unlocked via an electric lock control part 3c. In addition, when a warning mode is set to the first controller 2 in advance, the infrared ray emitting part 2c emits a warning signal in succession, and when the fact that this signal has been stopped longer than the specified time is judged by the controller 3, a warning buzzer 3d is buzzed.

This will be explained with reference to the flowcharts of FIGS. 5 and 6 showing the work performed by the system.

First, the CPU 2111 of the controller 2 starts operating when the power is turned on, and in the first step S1 reads the switching state of the state changeover switch 2b, and thereby determines whether the state changeover switch 2b is in the normal mode or the warning mode. do. When the state changeover switch 2b is in the normal mode, the process proceeds to step S2, where it is determined whether the locking switch of the input switch group 2a has been turned on by pressing the locking button 2aI. When the determination in step s2 is No, the process proceeds to step s3, where it is determined whether or not the unlock switch of the input switch group 2a has been turned on by pressing the unlock button 2at. If the determination in step S3 is also No, the process returns to step s1, and steps 81 to S
3 is repeated, and as long as the state changeover switch 2b is in the normal mode, the process waits until the determination in either step S2 or S3 becomes YES.

Now, when the determination in step S2 is YES, that is, when the lock button 2a is pressed, step S
The process proceeds to step 4, where the infrared light emitting section 2c is driven to send out a locking signal using infrared light. On the other hand, the determination in step S3 is Y.
When ES is reached, that is, when the unlock button 2az is pressed, the process proceeds to step S5, where the infrared light emitting section 2c is driven to send out an unlock signal using infrared light.

Further, when the state changeover switch 2b is switched to the warning mode and the determination in step S1 is warning, the process proceeds to step S6, where the infrared light emitting section 2C is driven to send out a warning signal in infrared rays.

The locking signal and the unlocking signal are sent out in a predetermined pattern for a predetermined time according to the operation of the locking/unlocking buttons 2a+ and 28z, and the warning signal is sent out continuously during the period when the state changeover switch 2b is switched to the warning mode. , the pattern is, for example, a 1 second transmission followed by a 1/4 second pause.

Next, the CPU 3g of the sub-controller 3 starts operating upon power-on, and in the first step S11 determines whether or not there is a signal received by the infrared light receiving section 3b. When the determination in step S11 is NO, that is, when the infrared receiver 3b does not receive a signal, step S1
2, it is determined whether the lock switch of the input switch group 3a of the sub-controller 3 has been turned on by pressing the lock button 3al. When this determination is No, the process proceeds to step S13, where it is determined whether the unlock switch has been turned on by pressing the unlock button 3at, and when this determination is No, the process returns to step Sll, and the process proceeds to step S13. S
Repeat step 13.

Now, when the determination in step S12 is YES, that is, when the locking operation is performed on the sub-controller 3 side, the process advances to step S14, where a locking signal is applied to the electric lock 1 via the electric lock control section 3c. to perform the locking operation. On the other hand, when the determination in step S13 is YES, that is, when the unlocking operation is performed on the sub-controller 3 side, step S
15, where the electric lock 1 is activated via the electric lock control section 3c.
The unlocking operation is performed by applying an unlocking signal to.

When the infrared receiver 3b receives some kind of signal, the determination in step Sll becomes YES, and the process proceeds to step S16.In step S16, it is determined whether the signal received by the infrared receiver 3b is a normal type signal. Determine whether the signal is a warning type signal. If the received signal is of the normal type, the process proceeds to step 317, where it is determined whether the signal is a locking signal. When the determination in step S17 is No, the process proceeds to step 318, where it is determined whether the signal is an unlock signal, and when the determination is No, the process returns to step Sll.

On the other hand, when the determination in step S17 is YES,
That is, when the locking signal is received, the process proceeds to step S19, where a locking signal is applied to the electric lock 1 via the electric lock controller 3C to perform a locking operation. And the above step S
When the determination in Step 18 is YES, that is, when an unlocking signal is received, the process proceeds to step S20, where an unlocking signal is applied to the electric lock 1 via the electric lock controller 3C to perform an unlocking operation.

By the way, when it is determined in step 316 that the signal received by the infrared light receiving section 3b is a warning signal, the process proceeds to step S21, where it is determined whether or not the signal is present for a predetermined time or longer. In this step S21, for example, the output of the infrared light receiving section 3b is monitored for a predetermined period of time at regular intervals. If there is no warning signal continuously during monitoring at specified time intervals, as shown in FIG. 7, an intruder It is determined that the warning signal has been interrupted, and the process proceeds to step S22, where an alarm signal is sent to the alarm buzzer 3d to generate an alarm. If there are continuous warning signals during monitoring at specified time intervals, it is determined that there is no intruder X, the process returns to step Sll, and the above-described operations are repeated.

In the embodiment described above, the lock signal, unlock signal, and warning signal are only sent unilaterally from the controller 2 to the sub-controller 3, but mutual communication is performed between the controller 2 and the sub-controller 3. The reliability of operation can be increased by

By the way, when the controller 2 is set to the alert mode, the determination in step S31 causes the controller 2 to proceed to step S3.
The process proceeds to step 7, where a warning signal is sent to the infrared receiving/emitting unit 2f. Thereafter, the process proceeds to step S38, where it is determined whether or not the warning signal is normally returned from the sub-controller 3. If not, the warning buzzer 2g is activated to generate an alarm in step S39. If the warning signal is returned normally, the process returns to step S31 and the above-described operations are repeated.

Note that when the determination in step S34 is YES, that is, when the time on the calendar clock is within the predetermined time period, the process proceeds to step S37, and a warning signal is generated even if the state changeover switch 2b is in the normal mode. ing.

As shown in FIG. 10, the CPO 3g of the sub-controller 3 in FIG. 8 starts operating in response to power-on, and in the first step S41 determines whether a signal is coming to the infrared receiving/emitting unit 3h. . If no signal is received, the process advances to step S42, where it is determined whether there is a locking operation, and if there is no locking operation, the process advances to step S43, where it is determined whether or not there is an unlocking operation. The determination in step 342 is YES.
When S, that is, when there is a locking operation, step S
The process proceeds to step 44, where a locking operation is performed and a completion signal of the operation is sent from the infrared receiving/emitting section 3h. Further, when an unlocking operation is performed and the determination in step s43 is YES, the process proceeds to step 345, where the unlocking operation is performed and a completion signal of the operation is sent from the infrared receiving/emitting unit 3h.

If any signal is coming from the controller 2 to the infrared receiving/emitting section 3h, the determination in step S41 is YES, and the process proceeds to step S46. In step S46, it is determined whether the signal is normal or warning, and if the signal is normal, step S46 is performed.
The process proceeds to step 47, where it is determined whether the signal is a locking signal. If it is not a lock signal and the judgment is No, step 34
The process proceeds to step B, where it is determined whether the signal is an unlock signal or not, and if this determination is NO, the process returns to step S41.

When the determination in step 347 is YES, that is, when a locking signal is received from the controller 2, the process proceeds to step 349, where a locking operation is performed, and a completion signal of the operation is transmitted from the infrared receiving/emitting unit 3h. Further, when the determination in step 348 is YES, that is, when an unlock signal is received from the controller 2, step S5
0, an unlocking operation is performed here, and a completion signal of the operation is transmitted from the infrared receiving/emitting unit 3h.

When the signal from the controller 2 is a warning signal, the process advances to step S51, where it is determined whether or not the warning signal has been present for more than a specified time, and when the determination is YES, the warning signal is sent to the infrared receiving/emitting unit 3h in step S52. through controller 2
If the determination is NO, the process advances to step S53, where the alarm buzzer 3d generates an alarm.
