The operation of this embodiment having the above-described configuration will be described below.

FIG. 5 is a functional block diagram showing a security device in an electronic lock device according to the present invention. FIG. 6 is a flowchart showing an example of the operation of the security device in the electronic lock device. All of these operations are performed within the control device 6.

With reference to FIGS. 5 and 6, the operation of the electronic lock device 2 will be explained first, and then the operation of the security device 3 will be explained.

The operation of the electronic lock device 2 will be explained below.

The output signal from the switch 5 when the switch 5 is operated is a gate part 63, a fixed number storage part 64, a fixed number comparison part 65, an arbitrary number storage control part 66, an arbitrary number comparison control part 68, and an arbitrary number comparison part. 69. Since switch 5 has been operated, the process moves to steps 5601, 5602, and 5603. If the output signal is a fixed number, the fixed number stored in advance is output from the fixed number storage section 64 and compared with the number input from the switch 5 in the fixed number comparison section 65. Here, it is assumed that a number for operating "lock related" is inputted from switch 5 as a fixed number. Then, the output signal from the fixed number comparison section 65 enables the arbitrary number storage control section 66 and the arbitrary number comparison control section 68 to operate.
Moving on to 604. When the code is not stored in the arbitrary number storage unit 67, the arbitrary number storage control unit 66 is activated, and the code is set in the arbitrary number storage unit 67 by operating the switch 5 (that is, from step 5604 to step 8606 is executed.

Next, when switch 5 is operated, steps 5601 to 5
The process moves to step 604, and it is determined that the code has been set by the arbitrary number storage control unit 66, so step 860
7K transition. Then, the arbitrary number comparison control section 68 is activated, and the comparator 69 compares the stored contents from the arbitrary number storage section 67 to determine whether the output signal output from now is "unlocked" by operating the switch 5. . As a result of the comparison in the comparing section 69, if it is determined that the door is "locked", the process moves to steps 8607 to 5609, and the door lock actuator 7 is operated to lock the door. If it is determined that this is not the case, the process moves from step 8608 to step 5601.

Here, the case of "unlocking" will be explained.

When the switch 5 is operated and the code is input, step 86
01 to 5604 and then proceeds to step 5607. The output signal input from the switch 5 is supplied to an arbitrary number storage control section 68 and a comparison section 69. The control section 68
causes the storage section 67 to supply the code to the comparison section 69.

In this comparison section 69, when the code input from the switch 5 and the code supplied from the storage section 67 match, the door lock actuator 7 is activated to unlock the door (
step 5610). Next, if the security device 3 is set to the operating state, it is reset (step 5611).

The above is the operation of the electronic lock device 2.

Next, the operation of the security device 3 will be explained below.

First, the switch 5 is operated to enable the security device 3 operator to operate. By inputting the fixed number through the switch 5, the gate section 63 for the security device 3 is operated. This is nothing but a transition to steps 5601-8603 and 5612. Next, two or more predetermined switches of the switches 5 are pressed simultaneously, for example (step 8612). If this is a set of security devices 3, the process moves to steps 5613 and 5614. In step 5614, a timer (
(realized by a program), the process does not proceed to step 5615 until a certain period of time has elapsed. After a certain period of time has passed in this step 8614, the security device 3 is set (step 86
15). This is because the output signal of the switch 5 is supplied from the gate section 63 to the setting control means 62, the control means 62 is activated, the timer within the control means 62 starts measuring time, and when a certain period of time has elapsed, the alarm command forming means This means setting 61 to the operating state. Since the small security device 3 is set in this way, steps 8601 and 5615 are performed thereafter.
and 5616. That is, the setting control means 62 controls the setting control unit 62 for a certain period of time (for example, 4
0 seconds), the command forming means 61 is not activated;
After this time has elapsed, the command forming means 61 is brought into operation.

Let us now assume that the door 4 is opened, the door switch 8 is closed, and the interior light 10 is turned on.

Then, the process moves to step 5617. door switch 8
The signal 100 that is generated when the indoor light 10 is turned on when the switch is closed is applied to the alarm command forming means 61. Then, in step 5617, the alarm command forming means 61 forms the situation report command 200 and supplies it to the alarm generating means 10. The alarm generating means 10 receives the alarm command 200 and generates an alarm sound. In the case of Figure 3, game) 11C
is opened and the signal from the oscillation circuit 11B is amplified by the amplifier circuit 11D to drive the speaker 11E. In the case of Fig. 4, the relay contacts 11r41.11rf12 are closed and the buzzer 11
G or honk. Such an operation is nothing but activation of the security device 3 in step 8618.

In this embodiment, since the security device 3 is reset when the door is unlocked, it is necessary to set the security device 3 each time.

FIG. 7 is a flowchart showing another example of the operation of the security device of the electronic lock device according to the present invention. In FIG. 7, parts having the same functions as those in FIG. 6 are given the same reference numerals, and their explanations will be omitted.

The difference between the operation example in FIG. 7 and that in FIG. 6 is that when it is determined in step 8613 that the security device 3 is not set, it is determined to reset the security device 3 (step 5701) and the security device 3f is determined to be reset (step 5701). Flow for resetting (step 5702), flow for stopping the security device 3 provided in place of step 5611 in FIG. 6 [step 5703], and step 5616.
In step 8703, when it is determined that the door switch 8 is closed and the interior light 1o is turned on, the security device 3 is activated if the security device 3 is not stopped (step 5704). The point is that

Can this operation example also be explained using the functional block diagram shown in FIG. 5? It's not even 5t. Further, the operation of the electronic lock device 2 is the same as that described in FIG. 6 above.

In short, in this operation example, the security device 3 is set to an operating state (steps 5613 and 8614), or its operating state is reset (steps 5701 and 57).
02), it is necessary to perform a predetermined operation on the switch 5 (for example, press the L/C button three times within a certain period of time).

Of course, when the switch 5 is unlocked by inputting the code, the operation of the security device 3 is stopped in step 5703, so the security device 3 does not operate (step 5704).

By doing this, you will not forget to set the security device 3 to the operating state, and each time you lock the door, the security device 3
This has the advantage of eliminating the hassle of setting the device to an operating state.

Of course, when the operation of the security device 3 is unnecessary, it goes without saying that the security device 3 may be kept in a reset state.

Note that the flowcharts for each of the above operations are shown only to explain the operations of the electronic lock device 2 and the security device 3, and therefore, other portions of the operation flow are omitted.

Furthermore, although the timer of the alarm setting control means 62 was realized by a program in the above embodiment, it is a one-shot program that operates when a signal is continuously input for a certain period of time, for example, in the interface circuit 630 (FIG. 3). It may be realized by providing a multi-vibrator. Furthermore, similarly, a pie break may be provided between the output 606 and the buffer 11.

〔Effect of the invention〕

As described above, according to the present invention, when two or more predetermined switches out of a plurality of switches are operated, the door is activated, and when the door is opened, an alarm sound is emitted to notify the surroundings. As a result, crime prevention settings can be easily performed, and the door is prevented from being opened, thereby preventing crime from occurring.
