The infrared transmitting means comprises a modulation circuit 56 for PPM-modulating the unlocking command signal, for example, and an infrared light emitting circuit 57 for blinking a light emitting element 57a in accordance with the output of the modulation circuit 56. The light emitting element 57a is a semiconductor element such as a light emitting diode.

The electric lock main body 2 installed on the door includes a lock mechanism 61 including a lock having a deadbolt and an actuator for driving the advancing and retreating of the deadbolt, and receives and demodulates transmitted infrared transmission data. An infrared receiving means for outputting a locking / unlocking command signal, and a locking / unlocking control means for controlling locking / unlocking of the lock mechanism 61 based on the locking / unlocking command signal output from the infrared receiving means.

The infrared receiving means comprises an infrared light receiving circuit 62 for receiving infrared transmission data and converting it into a corresponding electric signal, and a demodulation circuit 63 for PPM demodulating an output signal of the infrared light receiving circuit 62. . The infrared light receiving circuit 62 includes a light receiving element 62a such as a light receiving transistor.
including.

The locking / unlocking control means performs predetermined signal processing based on a ROM 64 storing a personal identification number and a locking / unlocking command signal output from the infrared receiving means, and controls locking or unlocking of the lock mechanism 61. And a CPU 65 that performs the processing. The ROM 64 also stores a control program for the CPU 65.

The control operation of the locking / unlocking control means is as follows. The CPU 65 compares the password contained in the locking / unlocking command signal input from the infrared receiving means, that is, the transmitted password with the password stored in the ROM 64. When the transmitted password matches the stored password, the CPU 65 determines whether the transmitted command signal is the locking command signal or the unlock command signal included in the locking / unlocking command signal. Judge. If the transmitted command signal is a locking command signal, the CPU 65 operates the actuator of the lock mechanism 61 to advance the deadbolt to perform locking.

By the way, when the user goes out after locking the front door, or when he leaves the car by locking the car door in a parking lot, he may be anxious about whether or not he / she has locked the car immediately or after a while. . Locking is the most important act for ensuring safety in daily life, but is often performed almost unconsciously. For this reason, it may not be possible to remember whether or not the lock has been performed, and in such a case, the above-mentioned anxiety is attacked. It seems that many people have experienced such anxiety.

With regard to mechanical locks such as cylinder locks, for example, JP-A-6-212840, JP-A-7-233662 and JP-A-10-238180.
As disclosed in the above publication, various lock confirmation devices have been conventionally proposed, but none of them are commercially available and widely used.

In an electric lock device in which a lock command signal or an unlock command signal transmitted by infrared rays or radio waves from a remote control key is received and an electric lock main body is locked or unlocked, as shown in FIG. The light 59 is used as a lock confirmation means. That is, the indicator light 59 is a semiconductor light emitting element such as a light emitting diode, and is turned on by the CPU 55 based on the transmission of the locking command signal.

Infrared receiving means for receiving and demodulating transmitted infrared transmission data and outputting a monitor signal; and displaying the indicator light 5 based on the monitor signal.
9 is added to the remote control key 1.

In the electric lock device shown in FIG. 5, the indicator lamp 59 is flushed for a predetermined time at the time of locking to make it easy for the user to confirm the locking. Alternatively, without flashing, by turning on the light at the same time as locking and continuing to light until the user turns off, reconfirmation after locking can be performed. However, if the display lamp 59 is kept displayed for reconfirmation of the lock, power is wastefully consumed, and there is a problem that the number of times of battery replacement of the remote control key 1 is greatly increased.
In addition, the indicator lamp may be turned on due to an erroneous operation, and there is a problem that the reconfirmation of the lock lacks certainty.

[0016]

And a CPU 35 that performs the processing. The ROM 34 also stores a control program for the CPU 35.

The control operation of the locking / unlocking control means is as follows. The CPU 35 compares the password contained in the locking / unlocking command signal input from the infrared receiving means, that is, the transmitted password with the password stored in the ROM 34. If the transmitted password matches the stored password, the CPU 35 determines whether the transmitted command signal is a command signal included in the locking / unlocking command signal, that is, whether the transmitted command signal is a locking command signal or an unlocking command signal. Judge. If the transmitted command signal is a locking command signal, the CPU 35 operates the actuator of the lock mechanism 31 to advance the deadbolt to perform locking. If the transmitted command signal is an unlock command signal, the CPU 35 operates the actuator of the lock mechanism 31 to retract the deadbolt to unlock. As the actuator of the lock mechanism 31, a solenoid or a DC motor is used.

Next, with reference to FIG. 4, the operation of locking confirmation and reconfirmation of locking of the electric lock device according to the present invention will be described.

The lock confirmation and the lock reconfirmation of the electric lock device according to the present invention are performed by the remote control key 1. That is, in the remote control key 1, the CP
U15 activates the lock / unlock and lock confirmation program when any one of the lock switch 11, unlock switch 12 and reconfirmation switch 13 is operated and an operation signal is input.
When detecting the operation signal (101), the CPU 15 checks whether or not the input operation signal is a lock signal (102). If it is determined in step 102 that the signal is a locking signal, the CPU
15 reads the password stored in the ROM 14 and generates a locking command signal including the password and the locking signal and having a predetermined format (103). Subsequently, the CPU 15 causes the transmitting means to transmit the locking data obtained by modulating the locking command signal (104). Next, CP
U15 stores the current time measured by the clock circuit 23 in the RAM.
The lock time is stored in the lock time storage unit 20a (105) and the lock time is displayed on the liquid crystal display 19 for a predetermined time, for example, 5 seconds (106). When the display of the lock time ends,
The locking / unlocking and locking confirmation program ends.

As described above, the locking time is displayed on the liquid crystal display 19 of the remote control key 1 at the time of locking, so that the user can easily and reliably confirm the locking. Moreover, since the display of the lock confirmation is not the mere light but the lock time, the user memorizes the lock time together with the lock time in the mind. That is, an unconscious locking action becomes a conscious locking action. Therefore, by using the electric lock device according to the present invention, it is possible to greatly reduce anxiety about locking that is attacked immediately after going out or immediately after leaving the car after parking, that is, it is not possible to remember whether or not locking has been performed. Can be expected. This is because humans remember the past using time as a keyword.

If it is determined in step 102 that the input operation signal is not a lock signal, the CPU 15
It is checked whether or not the lock time is stored in the lock time storage unit 20a of M20 (107). If it is determined in step 107 that the lock time is stored, it is checked whether or not the input operation signal is an unlock signal (108). Step 1
If it is determined at 08 that the signal is an unlock signal, the CPU 15
The personal identification number stored in the OM 14 is read out, and an unlock instruction signal including the personal identification number and the unlock signal and having a predetermined format is generated (109). Then CPU15
Causes the transmission means to transmit the unlocking data obtained by modulating the unlocking command signal (110), and further erases the locking time stored in the locking time storage unit 20a of the RAM 20 (11).
1). When the erasure of the locking time ends, the locking / unlocking and locking confirmation program ends. If it is determined in step 107 that the lock time is not stored, the lock / unlock and lock confirmation program ends.

If it is determined in step 108 that the input operation signal is not an unlock signal, that is, if it is determined that the input operation signal is a reconfirmation signal, the CPU 15
Causes the liquid crystal display 19 to redisplay the locking time read from the locking time storage unit 20a of the RAM 20 (112). The redisplay of the lock time in step 112 is continued for a predetermined time, for example, 5 seconds. When the re-display of the lock time ends, the lock / unlock and lock confirmation program ends.

As described above, since the lock time is displayed again on the liquid crystal display 19 of the remote control key 1,
The user can easily and surely confirm the lock again. The time when the lock time is displayed on the liquid crystal display 19 is
For example, a short time of 5 seconds. Until the unlock switch 12 is operated for unlocking, the user of the lock can reconfirm the lock anywhere, anytime, and any number of times.

The display of the lock time at the time of locking or reconfirmation is as follows:
The required minimum time is about 5 seconds. by this,
The power consumption of the liquid crystal display 19 is reduced so that the number of battery replacements of the remote control key does not increase significantly. In addition, characters such as "locking time" and "kakunin" may be displayed on the liquid crystal display together with the locking time.

In the electric lock device according to the present invention,
It is also possible to provide a means for monitoring whether locking or unlocking has been performed with a remote control key. The lock mechanism 31 includes a lock / unlock state detecting means for detecting a state of the lock mechanism 31 and generating a monitor signal indicating the lock state or the unlock state, and an infrared transmitting means for modulating the monitor signal and transmitting the same as infrared data. And an infrared receiving means for receiving and demodulating the transmitted infrared transmission data and outputting a monitor signal, and a monitor signal processing means for processing the monitor signal and turning on a liquid crystal display device. It is configured in addition to the control key 1.

In an electric lock device provided with means for monitoring whether or not locking or unlocking has been performed by a remote control key, the displayed locking time is determined by the generation time of the locking command signal or the transmission time of the locking data. In other words, the current time is measured by the timing means when the monitor signal indicating the locked state is transmitted from the electric lock main body 2. Therefore, the lock time display storage control means includes a ROM 14 storing a control program and an R having a lock time storage unit 20a.
It comprises an AM 20 and a CPU 15 for storing in RAM 20 the current time measured by the clock circuit 23 based on the monitor signal indicating the locked state.

In the electric lock device according to the present invention, the remote control key 1 can display the current time on the liquid crystal display 19 by operating the current time display switch. Since the function as the electronic timepiece does not directly relate to the present invention, a detailed description of its configuration and operation will be omitted.

[0043]

According to the electric lock device of the present invention, in the remote control key, the lock time is displayed on the time display means at the time of locking, the lock time is stored in the lock time storage means, and the lock time is stored at the time of reconfirmation. The locking time stored in the means is displayed again on the time display means. Therefore, the user of the electric lock device according to the present invention can easily and reliably perform lock confirmation and lock reconfirmation using the lock time as a keyword.
