Description

AUTOMATICALLY LOCKING AND UNLOCKING SYSTEM OF DOOR}

The present invention relates to an automatic door unlocking system for locking or opening a door using a wireless remote control by radio waves.

Since the locking of doors such as homes and offices is generally a lock type using a manual key, there is a problem such that the key cannot be opened by being removed or inadvertently opened by picking.

Therefore, it is proposed to install a ten-key near the door or the door and to enter the proof number from the tenkey to open the clasp (for example, Japanese Patent Application Laid-Open No. 59 (1984)). See publication 65174].

Moreover, the locking system using the remote control which uses a radio signal other than a tenkey is also proposed. In a locking system using a wireless signal, a manual release means using a key is usually provided in the case where the remote control is broken or the remote control is removed, and battery shortage is also taken into consideration.

However, the conventional automatic door unlocking system still has the following problems to be solved.

In the invention of Japanese Patent Application Laid-Open No. 59 (1984) -65174, Tenkey is used, and the door is opened by inputting a predetermined code in Tenkey, but the person who cannot remember the code, such as a child or dementia The old man had a problem that he could not open the lock. In addition, a person with a short height cannot operate a ten key disposed at a high position, and there is a problem that a person with a short height is difficult to operate with a ten key. Moreover, there existed a problem that by providing a tenkey, it became mechanically complicated and expensive. In addition, since the Tenkey is in contact with and operated, there is a problem that the device is easily deteriorated or broken.

In addition, in a lock system using a wireless signal, in addition to being unlocked and locked by the remote control, an automatic lock (auto lock system) that automatically locks when the door is closed is usually executed. For emergency use, in general, since a release means using a manual key is provided, there is a problem that it is easy to be subjected to picking.

Therefore, although it is considered to remove the manual key at all and use the radio signal or to open the lock only by the remote control, it was found that the following problems exist.

(1) Since there is an auto-lock system, everyone who opens and closes the door needs to carry the remote control at all times, which is very troublesome.

(2) Therefore, it is natural to be able to open the lock with the remote control from the room, and it is more convenient to have a device that unlocks the lock by manual operation from the room.In this case, the lock is opened from the room by manual operation, If the door is closed outdoors, the autolock system will operate and the lock will be locked and the door will not open.

The present invention has been made in view of the above circumstances, and the door can be opened and closed freely by using a wireless remote control by radio waves without installing keys or manual release means outside the door, and manual release from the room. It is an object of the present invention to provide an automatic door unlocking system that can be executed without obstacles.

And a door unlocking mechanism for releasing, a door open / close sensor for detecting that the door is closed, a control unit for outputting a lock and release signal to the door unlocking mechanism, and a radio wave signal corresponding to a predetermined ID code distinguished for each user. Possible remote control, a receiving unit for receiving radio signals from the remote control and sending a remote control signal to the control unit, an operation switch for sending a manual signal to the control unit, a battery for powering them, a battery, a door unlocking mechanism and a control unit And a receiving unit, and surface-mounting the operation unit of the operation switch Have a bracing. In the automatic door unlocking system according to the present invention, since a means for opening the lock using a key from the outside of the door is not provided, a person cannot open the door by picking operation from the outside.

In addition, when the door is closed, the control unit confirms that there is a remote control signal, (a) sends a release signal to the door unlocking mechanism, and there is no door open signal from the door open / close sensor within the first predetermined time. (b) a release signal is sent to the door unlocking mechanism and a door open signal is received from the door open / close sensor within the first predetermined time, and a door close signal is received from the door open / close sensor within the second predetermined time from the door open signal. And (c) a remote control door opening / closing means for giving a locking signal to the door unlocking mechanism when the door closing signal is received from the door opening / closing sensor after the alarm has been issued once beyond the second predetermined time, and the door is closed. , When there is a manual signal from the operation switch, sends a release signal to the door unlocking mechanism, the door opening and closing sensor When the closing signal is issued, it has an operation switch door opening / closing means which receives a radio wave signal from the remote control and sends a locking signal to the door unlocking mechanism.

According to (a), even if there is a signal from the remote control and the lock is opened, if the door is not opened within the first predetermined time, the lock is automatically locked. Further, by (b), even if the lock is opened due to a signal from the remote control and the door is opened within the first predetermined time, the lock is automatically locked when the door is closed within the second predetermined time. And by (c), even if a warning sounds once beyond a 2nd predetermined time, when a door is closed, a lock will lock automatically.

In the automatic door lock release system according to the present invention, the door open / close sensor issues a door open signal to the operation switch door open / close means after the release signal is sent to the door lock release mechanism, and the door open / close sensor then generates a door close signal. If it detects and there exists a manual signal of an operation switch, you may have a means to send a lock signal to a door lock release mechanism. Accordingly, when the lock is opened by the operation switch, the lock is not automatically locked even if the door is opened and closed once, so that the door does not open even when the user goes outside without the remote control.

In the automatic door unlocking system according to the present invention, the controller may be provided with a battery consumption warning means for detecting the voltage of the battery and lighting the light emitting diode in a pulsed manner if the voltage is below a certain voltage. This can prevent the automatic door unlocking system from becoming unusable due to lack of battery capacity. And it is more preferable that the battery consumption warning means be operated from about a month before the battery becomes practically disabled.

In the automatic door unlocking system according to the present invention, when the receiver does not receive a predetermined radio wave signal, an intermittent power supply with an on time of less than an off time is executed from the battery to the feed circuit of the receiver. In the case where the receiver receives the radio signal and the operation switch is operated, the power supply control circuit may be provided to temporarily operate the receiver and to make the controller operate. As a result, it is possible to prevent battery consumption during a period in which the locking and unlocking operation is not actually performed as much as possible, and the automatic door unlocking system can be normally operated for a long time.

In addition, a conventional knob type opening / closing handle (not shown) is attached to the interior side of the door 11, and a conventional knob (not shown) which is integrally connected to the opening / closing handle described above on the outdoor side of the door 11. Equipped with an open handle. In addition, the base (one side) of the door 11 is conically joined by a hinge (not shown) on one side to which the door opening 21 corresponds, and the front (the other) of the door 11 is different. The side part) can rotate in the front-back direction, and can open and close the door opening 21.

The rectangular box-shaped casing 19 formed by standing the circumferential wall 23 on the circumferential edge of the bottom plate 22 is fixed to the interior side of the door 11 by connecting bolts or the like. Similarly, a rectangular box-shaped cover plate 24 is detachably fitted to the casing 19 to form a storage space 25 therein. Further, in the upper part of the storage space 25, a partition wall 29 provided in parallel with a gap from the bottom plate 22 is formed to have a middle layer structure, and the bottom plate 22 and the partition wall ( In the space between 29), the control part 14 mainly having the printed wiring board which mounted the circuit comprised from an LSI element etc. is formed. In addition, in the space between the partition wall 29 and the cover plate 24, a power supply unit 30 composed of a plurality of, for example, four batteries 18 is formed. And in the automatic door lock release system 10, it is exposed to the outer side of the door 11, and the release means of manual operation by a key from the outer side is not provided.

With reference to FIG. 3, FIG. 4, the door lock release mechanism 12 is demonstrated. The door unlocking mechanism 12 is formed on the other side of the door opening 21 by the electromagnetic solenoid 26 driven by the lock and release signal sent from the control unit 14 and the electronic solenoid 26. It has a metal rod-shaped plunger 27 which advances and retreats toward one plunger engaging hole 28.

Moreover, the plunger 27 is arrange | positioned so that it may protrude toward the plunger engaging hole 28 from the hole 28a formed in the circumferential wall 23 whole side of the casing 19. As shown in FIG. When the door 11 is opened, the plunger 27 is substantially received from the whole of the door 11 toward the base side, and the plunger 27 does not contact the wall 20 by opening and closing the door 11. have. In addition, when locking the lock, the plunger 27 advances to the wall 20 side and is inserted into the plunger engaging hole 28.

As shown in FIG. 3, the receiver 16 is attached to the inner upper surface of the cover plate 24, and the antenna 32 of the receiver 16 is attached to the cover plate 24. As shown in FIG. Here, with reference to FIG. 2, the receiver 16 is demonstrated in detail. The receiver 16 employs a well-known superheterodyne system, and includes an amplifier circuit 33, a mixed detector 34, a local oscillator 35, an intermediate frequency amplifier 36, and a waveform shaper 37. Consists of In the present embodiment, the reception unit 16 cooperates with the control unit 14 to operate intermittently at all times. At the time of operation, the reception unit 16 can receive radio signals from the remote control 15, which is a transmitter. After the predetermined radio wave signal from (15) is received, the power supply control circuit 38 which can receive continuously is provided. In other words, when the receiver 16 does not receive the predetermined radio wave signal, the power supply control circuit 38 executes intermittent power supply with a shorter time than the off time for the power supply circuit from the battery 18 to the receiver 16. When the reception unit 16 receives the radio wave signal, the operation of the reception unit 16 can be temporarily continued, and the sleep state of the control unit 14 can be released and brought into an operation state, thereby reducing the consumption of the battery 18. You can do as little as possible. And even when the operation switch 17 is operated, the power supply control circuit 38 is made to operate for a fixed time (for example, about 2 minutes).

Next, the remote control 15 which transmits the radio wave signal which the reception part 16 can respond is demonstrated. There are a plurality of remote controls 15 for each family member, and each of the remote controls 15 has a function of transmitting a radio signal corresponding to an ID code of a user (for example, a family member) to the receiver 16. Have In addition, since the remote control 15 is a transmission by electromagnetic waves (electromagnetic space transmission), for example, it is possible to reliably transmit a radio signal toward the receiver 16 from a position 10 m away from the door 11. Therefore, it is possible to reliably transmit the radio wave signal to the receiver 16 from the outdoor side.

3 and 4, the operation switch 17 for manually locking or opening the door 11 from the room will be described. The operation switch 17 is a switch by push button operation, and is attached to the center part of the storage space 25. By pressing the operation switch 17, a manual signal is sent to the control unit 14, a lock and release signal is sent from the control unit 14 to the door unlocking mechanism 12, and the electronic solenoid 26 is operated to operate the plunger. (27) may advance.

Next, the control unit 14 will be described in detail with reference to FIGS. 1 and 3.

The control unit 14 is composed of a CPU (central computing unit) 39, a ROM 40, a RAM 41, an input interface 42, and an output interface 43.

The input interface 42 is connected to a receiver 16 that receives radio signals from the remote controller 15, a door open / close sensor 13, and an operation switch 17. Here, the door opening / closing sensor 13 is for detecting the state in which the door 11 is completely locked, and vice versa, and when the door is not in the locked state, a specific time (for example, After 30 seconds, the alarm buzzer 44 is operated to notify the bad closed state.

On the other hand, the door unlocking mechanism 12, the light emitting diode 18a, and the alarm buzzer 44 are connected to the output interface 43.

In addition, the controller 14 is provided with a battery consumption warning means to detect the voltage of the battery 18, and when the voltage of the battery 18 is lower than or equal to the predetermined voltage, the light emitting diode 18a is turned on in a pulse manner. In addition, the electrical capacity of the battery 18 is reduced to prevent the automatic door unlocking system 10 from becoming inoperative. As shown in FIG. 1, the power supply unit 30 is configured to be capable of feeding power to the door lock release mechanism 12, the door opening / closing sensor 13, the control unit 14, the receiving unit 16, and the alarm buzzer 44. have.

Moreover, the control part 14 has the remote control door opening / closing means which locks and opens the door 11 of the closed state by the remote control 15, and the operation switch door opening / closing means which locks and opens by the operation switch 17. FIG.

Next, with reference to the flowchart shown in FIG. 5, the locking and releasing operation | movement by the automatic door unlocking system 10 is demonstrated. In addition, when "Y" is attached to the ending of the step, it indicates branching toward "YES", and when "N" is attached to the ending of the step, it indicates branching toward "NO".

(1) When opened with the remote control (15)

First, when the user (for example, the returnee) presses the switch of the remote control 15 in front of the door 11 (outdoor) from the state in which the door 11 is closed (step 100Y), the remote control ( The radio wave signal including its ID code is transmitted from the 15 to the receiver 16. Then, the remote control signal is transmitted from the receiving unit 16 that has received this radio signal to the control unit 14 (step 101Y). The remote control door opening and closing means of the control unit 14 confirms reception of the remote control signal, and sends a release signal to the door lock release mechanism 12. Thereby, the electromagnetic solenoid 26 of the door lock release mechanism 12 is energized, retracts the plunger 27 from the plunger engaging hole 28, and opens the door 11 (step 102).

In order to save power, the CPU 39, which is in the sleep state while not receiving the radio wave signal from the receiving unit 16, is released from the sleep state by the input of the above-described remote control signal, and enters the operating state. The control unit 14 also registers an ID code included in the radio signal from the remote control 15 registered in advance. In the control unit 14, when the confirmation of the ID code is finished, the alarm buzzer 44 sounds a beep (e.g., beep, beep, beep, beep) with a tone or intermittent sound assigned to each user. You can tell someone in your room who has returned home. The notification sound may be different kinds of music.

After release of the door 11 (step 102), the remote control door opening / closing means of the control unit 14 sends a roll signal to the door unlocking mechanism 12 in the following cases (a) to (c). The door 11 is locked by the unlocking mechanism 12.

(a) Even when the timer count for the first predetermined time, for example, 10 seconds ends (step 103Y), when the door 11 is closed (step 106Y), the door 11 is locked (step 107). . That is, when the door is not opened within the first predetermined time after receiving and releasing the remote control signal, the door is locked. Then, the open and closed states of the door 11 are detected by the door open / close sensor 13 (hereinafter, the same).

(b) When the door 11 is open (step 104Y) before the end of the timer count for the first predetermined time, for example, 10 seconds (step 103N), the door 11 is opened and then the second If the door 11 is closed (step 106Y) before the end of the timer count for a predetermined time, for example, 30 seconds (step 105N), the door 11 is locked (step 107).

(c) If the door 11 is open (step 104Y) before the end of the timer count for the first predetermined time, for example, 10 seconds (step 103N), the door 11 is opened and then the second When the timer count for a predetermined time, for example, 30 seconds ends (step 105Y), a notification sound is issued from the alarm buzzer 44 as an alarm (step 108). Here, when the door 11 is closed (step 109Y), the alarm is stopped (step 110) and the door 11 is locked (step 107).

In this way, when the door 11 is released by the remote control 15, the remote control 15 sends a radio wave signal again on the condition that the door 11 is closed, or the operation switch ( Since the door 11 is automatically locked without pressing 17), the locking operation is not cumbersome and is very convenient.

(2) When it is opened by operation switch 17

When the user (for example, a home worker) pushes the operation switch 17 in front of the door 11 (indoor) from the state in which the door 11 is closed (step 100Y), the manual operation is performed (step 101N, step 111Y). The operation switch door opening / closing means of the control unit 14 to which a signal is input sends a release signal to the door unlocking mechanism 12, and the door 11 is opened by the door locking release mechanism 12 (step 112). After the release of the door 11, the operation switch door opening and closing means of the control unit 14 issues a lock signal to the door unlocking mechanism 12 in the following cases (d) to (f), and the door 11 is released. Is locked.

(d) When the door 11 is closed (step 113N), the door 11 is locked by the radio wave signal of the remote control 15 (step 116Y) (step 107). That is, when it is opened by the operation switch 17, even if the operation switch 17 is pressed with the door 11 closed, it will not be locked.

(e) After opening the door 11 (step 113Y), closing the door 11 (step 114Y) and pressing the operation switch 17 (step 115Y), the door 11 is locked (step 107).

(f) After opening the door 11 (step 113Y), closing the door 11 (step 114Y) and pressing the remote control 15 (step 115N, step 116Y), the door 11 is locked (step 107).

As a result, when the door 11 is released by the operation switch 17, even when the vehicle is out without carrying the remote control 15 due to garbage disposal or the like, the door is automatically released as in the case of release by the remote control 15. 11) is not locked, so it is not possible to enter the outdoors. Moreover, even if the door 11 is left open, the alarm buzzer 44 does not sound.

The present invention is not limited to the above-described embodiments, and changes can be made without departing from the spirit of the present invention. For example, the automatic door of the present invention in combination with some or all of the above-described embodiments and modifications. The configuration of the unlocking system is also included in the scope of the present invention.

For example, the alarm release button may be provided by the remote control door opening and closing means so as not to sound an alarm issued over the second predetermined time. Thus, when the door is opened for a long time, it is possible to prevent the alarm from sounding. In addition, the control unit may be provided with an illegal intrusion alarm means for operating the alarm buzzer when the door lock release mechanism of the automatic door lock release system is forcibly opened.

Moreover, you may provide a cover in the operation switch 17 so that an illegal intruder cannot operate the operation switch 17 from a peep hole, a letter box, etc. The door 11 may be opened only by bringing the remote control 15 closer to the receiver 16.

In the automatic door unlocking system according to claims 1 to 4, since the automatic door lock release system is mounted inside the door, exposed to the outside of the door, and is not provided with a release means for manual operation by a key, It cannot be released by the picking operation.

Locking and unlocking of the door is performed by a remote control that emits a radio signal containing a predetermined ID code. And since the control part which sends a lock signal and a release signal to the door lock release mechanism which locks and unlocks a door is equipped with the remote control door opening / closing means demonstrated above, it automatically executes auto-lock when a door is closed, If is open, an alarm can be issued.

Moreover, since the operation switch door opening-and-closing means demonstrated above is provided, the door can be opened from the manual operation switch provided in the inside of the door. Thereby, if it is from the inside of a door, it can release by means other than a remote control.

In particular, in the automatic door lock release system according to claim 2, after the release signal is sent to the door lock release mechanism, the door open / close sensor issues an open signal, and then the door open / close sensor sends a close signal. When it detects and there is a manual signal of an operation switch, it has a means to send a lock signal to a door unlocking mechanism, so when a door is opened by manual operation from the inside of the door, it differs from the case of remote control operation. Even if the door is closed after the door is opened, the door is not automatically locked, and the door is automatically locked so that the door cannot be pushed in.

In the automatic door unlocking system according to claim 3, since the battery consumption warning means described above is provided, it is possible to know the battery consumption in advance, thereby preventing inoperability due to battery consumption.

And since the power supply control circuit demonstrated above is provided in the automatic door lock release system of Claim 4, the battery life can be extended.
