Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electric lock that performs locking and unlocking without wiring.
[0002]
[Prior art]
The electric lock is attached to the door, and an input device such as a switch or a numeric keypad installed in the door is operated to input a personal identification number. The input personal identification number is set in advance with the personal identification number set in the controller. When they coincide with each other, a control signal is output from the controller to actuate the actuator so that locking or unlocking is performed.
[0003]
In addition to the switch and numeric keypad, the input device is a card reader that reads a card with a password stored in advance. When the read password is checked by the controller and matched, the electric lock is unlocked. Some are also known.
[0004]
Conventionally, when the electric lock actuator having the above-described configuration is operated to lock and unlock, electric power is supplied between the door and the door frame through the wiring using an energizing metal fitting or built into the electric lock body. Electricity was supplied from the battery.
[0005]
However, in the configuration in which power is supplied using a current-carrying metal fitting, there is a risk of disconnection or short-circuiting with long-term opening and closing of the door, causing problems in terms of structure and safety.
[0006]
In addition, in the configuration in which power is supplied by the battery built in the electric lock, especially in the case of an electric lock equipped with an input device, the power supply of the input device is also covered by the battery. It was necessary to replace the battery and its management was troublesome.
[0007]
Therefore, as an apparatus that has solved the above-described problems, an electric lock apparatus that incorporates a battery in an electric lock and stores electricity in the battery using electromagnetic coupling is known.
[0008]
As shown in FIG. 5, the electric lock device includes an electric lock main body 72 provided on the door 71 side to be unlocked when data stored in advance and input data match, and a frame side. An indoor control box 75 on the door frame 74 side, in which the communication head 73 is embedded, is schematically configured.
[0009]
The indoor control box 75 includes an AC oscillator 77 that generates an alternating current having a predetermined frequency and supplies the alternating current to the power supply coil 76 of the frame-side communication head 73, a communication transmission / reception coil 78 provided in the frame-side communication head 73, and A communication control unit 80 connected to the center side via a communication line 79 is provided. The door-side communication head 81 facing the frame-side communication head 73 is provided with a power receiving coil 82 and a communication transmitting / receiving coil 83 at positions facing the power supply coil 76 and the communication transmitting / receiving coil 78. The power receiving coil 82 is connected to a battery 87 that supplies a predetermined DC power source to the control unit 86 of the electric lock body 72 via a rectifier circuit 84 and a resistor 85.
[0010]
For example, in the case of a system using a key card, the control unit 86 reads data from the key card, compares the data with previously recorded data, performs arithmetic processing, and when the two data match, drives the solenoid to drive the electric lock. Is locked or unlocked. In addition, the control unit 86 exchanges data with the communication control unit 80 via the transmission / reception coils 78 and 83 for communication.
[0011]
In the electric lock device configured as described above, when the door 71 is closed, the door-side communication head 81 and the frame-side communication head 73 face each other, and the alternating current oscillated from the power supply coil 76 is used as the power receiving coil. 82. The received alternating current is rectified by the rectifier circuit 84 and then stored in the battery 87 and supplied to the controller 86.
[0012]
For example, the control unit 86 reads data recorded on the key card, and when the content matches the data recorded in advance in the memory, the control unit 86 drives the solenoid to lock or unlock the electric lock.
[0013]
[Problems to be solved by the invention]
However, in the electric lock device having the above-described configuration, since electromagnetic coupling is used to store electricity in the battery 87, the door side coils 82 and 83 and the frame side coils 76 and 78 are disposed in close contact with each other. The construction was troublesome.
[0014]
When the door is opened, the electromagnetic coupling between the door-side coils 82 and 83 and the frame-side coils 76 and 78 is released, and communication is immediately interrupted. It cannot be distinguished whether there is no signal response due to other factors. Accordingly, it has not been possible to reliably monitor remotely whether or not the electric lock is operating normally.
[0015]
Accordingly, an object of the present invention is to provide an electric lock that does not require battery replacement and that can be remotely operated and remotely monitored in order to eliminate the above drawbacks.
[0016]

[0019]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a schematic circuit diagram showing a first embodiment using a non-wired electric lock 1 according to the present invention.
[0020]
On the remote operation side outside the lock, for example, in a building, an energy supply signal transmission means 2 for transmitting an energy supply signal, an input means for transmitting a locking / unlocking command, a control signal transmission means 6 for transmitting a control signal, and a monitor Monitor signal receiving means 9 for receiving signals is provided.
[0021]
The energy supply oscillator as the energy supply signal transmission means 2 includes an AC power source 3 as an oscillation source wired indoors and a transmission loop antenna as a transmission unit 4. The frequency f is always continuously transmitted from the transmission loop antenna 4 to the energy supply signal receiving means 12 described later.1The energy supply signal is transmitted.
[0022]
Examples of the input means 5 include a card reader that reads a password of a card in which a password is stored in advance, in addition to a switch and a numeric keypad. A command for locking or unlocking the electric lock input by the input means 5 is sent to the control signal transmitting means 6.
[0023]
The control signal transmission means 6 includes a control signal generation circuit 7 and a transmission loop antenna as the transmission unit 8. The control signal generation circuit 7 receives a lock or unlock command from the input means 5 and receives a frequency f corresponding to the command.2(≠ f1) Control signal is generated. The control signal generated at this time is transmitted from the transmission loop antenna 8 to the control signal receiving means 16 described later.
[0024]
The monitor signal receiving means 9 includes a monitor signal demodulating circuit 10, a receiving loop antenna as a receiving unit 11, and a lock / unlock display lamp (not shown). The reception loop antenna 11 has a frequency f transmitted from a monitor signal transmission unit 25 described later.Three(≠ f1, F2) To receive a monitor signal indicating locking or unlocking.
[0025]
The monitor signal demodulation circuit 10 demodulates the received monitor signal. The lock / unlock display lamp includes, for example, a lock display lamp and an unlock display lamp connected to the monitor signal demodulation circuit 10. When the demodulated monitor signal indicates locking, the lock display lamp is turned on, and when the demodulated monitor signal indicates unlocking, the unlock display lamp is turned on.
[0026]
The electric lock side at the gate or the entrance has an energy supply signal receiving means 12 for receiving an energy supply signal, a power storage unit 15 for storing the power of the received signal, a control signal receiving means 16 for receiving a control signal, 1 A control circuit 19, a drive circuit 20, an actuator 21, a dead bolt 22, a detection switch 23, and a monitor signal transmission means 24 for transmitting a monitor signal are provided.
[0027]
The energy supply signal receiving unit 12 includes a receiving loop antenna and a rectifying circuit 14 as a receiving unit 13. The frequency f transmitted from the energy supply signal transmission means 21The energy supply signal is received by the reception loop antenna 13. The received energy supply signal is sent to the rectifier circuit 14. The rectifier circuit 14 includes a diode D and a capacitor C as shown in the figure, and converts the energy supply signal into a direct current and sends it to the power storage unit 15.
[0028]
The power storage unit 15 is composed of, for example, a large-capacity capacitor, and stores the power of the energy supply signal converted into a direct current. The stored electric power is supplied as drive power when the control signal receiving unit 16, the first control circuit 19, the drive circuit 20, and the monitor signal transmitting unit 24 are driven. Since the lifetime of the capacitor is expected to be 10 years, the use of the capacitor for the power storage unit 15 eliminates the need for battery replacement with a standard of 2 to 3 years for a storage battery.
[0029]
The control signal receiving means 16 includes a receiving loop antenna as a receiving unit 17 and a control signal demodulating circuit 18. The frequency f transmitted from the control signal transmission means 162These control signals are received by the reception loop antenna 17. The received control signal is sent to the control signal demodulation circuit 18. The control signal demodulation circuit 18 receives power supply from the power storage unit 15 and demodulates the received control signal. The demodulated control signal is sent to the first control circuit 19.
[0030]
The detection switch 23 includes a locking / unlocking detection switch that switches according to the advance / retreat of the dead bolt 22 and a door detection switch that switches according to the opening / closing of the door. From the detection switch 23, information on locking or unlocking due to advance / retreat of the dead bolt 22 and information on opening or closing according to opening / closing of the door are sent to the first control circuit 19 and the monitor signal transmitting means 24. .
[0031]
The monitor signal transmission means 24 includes a monitor signal generation circuit 25 and a transmission loop antenna as the transmission unit 26. The monitor signal generation circuit 25 is supplied with power from the power storage unit 15, and has a frequency f according to information on locking or unlocking of the detection switch 23 and information on opening or closing of the door.Three(≠ f1, F2) Monitor signal is generated. This monitor signal is transmitted from the transmission loop antenna 26 to the monitor signal receiving means 9.
[0032]
Next, the operation of the first embodiment will be described.
When a predetermined AC voltage is applied to the energy supply oscillator 2, the frequency f1The energy supply signal is always transmitted continuously. And frequency f1The energy supply signal is received by the reception loop antenna 13, converted into a direct current by the rectifier circuit 14, and sent to the power storage unit 15. The energy supply signal converted into a direct current is continuously stored in the power storage unit 15. The electric power from the power storage unit 15 is supplied as individual drive power when the control circuit 19, the drive circuit 20, and the monitor signal generation circuit 25 are driven.
[0033]
When locking or unlocking, a command for locking or unlocking the electric lock is input from the input means 5. More specifically, the personal identification number is input with the numeric keypad on the remote operation side, or the card is inserted into the card reader. The code number read by the numeric keypad or the card reader is sent to the control signal transmission means 6 as a lock or unlock command, and the frequency f2Control signal is transmitted. As the input means 5, when the operator need not be restricted, a simple push button for unlocking or locking may be used instead of the numeric keypad or card reader.
[0034]
Frequency f from control signal transmission means 62The control signal is received by the control signal receiving means 16, demodulated, and then sent to the first control circuit 19. The first control circuit 19 determines whether or not the password set in the first control circuit 19 in advance matches the input control signal (password).
[0035]
By the way, the first control circuit 19 is sent from the detection switch 23 information on locking / unlocking according to the advance / retreat of the dead bolt 22 and information on opening / closing according to opening / closing of the door. For this reason, when the correct password is authenticated by the determination in the first control circuit 19 and the lock / close information is sent from the detection switch 23, an unlock command is sent from the control circuit 19 to the drive circuit 20. . On the other hand, when the correct password is authenticated by the determination in the first control circuit 19 and unlocking / closing information is sent from the detection switch 23, a locking command is sent to the drive circuit 20.
[0036]
If the password set in the control circuit 19 in advance does not match the input control signal (password), that is, if the correct password is not authenticated, the unlocking command is sent to the drive circuit 20. Alternatively, the locking command is not output, and the electric lock is not unlocked.
[0037]
When an unlocking command is sent to the drive circuit 20, a current flows from the drive circuit 20 receiving power supply from the power storage unit 15 to the actuator 21. Thereby, the solenoid in the actuator 21 operates, the dead bolt 22 moves backward, and the electric lock is unlocked. On the other hand, when a command for locking is sent to the drive circuit 20, the dead bolt 22 is fitted into a receiving hole (not shown) by the operation of the actuator 21, and the electric lock is locked.
[0038]
Since the energization time of the actuator 21 in the above operation is only at the time of locking / unlocking switching, the power is consumed in a short time. Further, even when the actuator 21 is a DC motor instead of a solenoid and the dead bolt 22 is advanced and retracted by the DC motor, the DC motor is energized only for a short time during which the dead bolt 22 is advanced and retracted.
[0039]
Therefore, according to the first embodiment, the first control circuit 19 and the drive circuit 20 use the stored power only when necessary, so that the peak power consumption when actually used can be shortened. It is possible to operate with a power supply stored with weak radio waves. In addition, since power can be supplied without wiring, remote monitoring without wiring is also possible.
[0040]
Next, a second embodiment of the non-wired electric lock of the present invention will be described. FIG. 2 is a diagram in which the transmitters 4 and 8 and the receiver 11 are integrally formed on the remote operation side of the first embodiment. The electric lock side is the same as in the first embodiment.
[0041]
In the second embodiment, on the remote operation side, the input means 5, the second control circuit 27, the timing circuit 28, the AC power supply wired indoors, the control signal generation circuit 7, the remote operation side antenna unit 29, the filter F and a monitor signal demodulation circuit 10 are provided.
[0042]
As in the first embodiment, the input means 5 includes, for example, a card reader or the like that reads a personal identification number of a card in which a personal identification number is stored in addition to a switch and a numeric keypad. A command for locking or unlocking the electric lock input by the input means 5 is sent to the second control circuit 27.
[0043]
The second control circuit 27 sends a lock or unlock command to the control signal generation circuit 7 according to the presence or absence of the lock or unlock command, the lock or unlock information based on the monitor signal, and the presence or absence of the opening or closing information. And whether or not to switch the timing circuit 28 is determined. In response to this determination, a lock or unlock command is sent to the control signal generation circuit 7 and a timing signal is sent to the timing circuit 28.
[0044]
The control signal generation circuit 7 receives a locking or unlocking command from the second control circuit 27 and receives a frequency f corresponding to the command.2(≠ f1) Control signal is generated. The control signal generated at this time is transmitted from the remote operation side antenna unit 29 to the control signal receiving means 12 via the timing circuit 28.
[0045]
The AC power supply 3 wired indoors is continuously and continuously supplied to the remote operation side antenna unit 29 via the timing circuit 28.1Supply energy supply signal.
[0046]
The timing circuit 28 selectively turns ON / OFF according to the timing signal sent from the second control circuit 27, thereby sending one or both of the energy supply signal and the control signal to the remote operation side antenna unit 29. .
[0047]
The remote operation side antenna unit 29 is formed by integrally forming the transmission units 4 and 8 and the reception unit 11 on the remote operation side of the first embodiment. The remote operation side antenna unit 29 transmits an energy supply signal and a control signal, and receives a monitor signal. The received monitor signal is sent to the monitor signal demodulation circuit 10 via the filter F.
[0048]
The monitor signal demodulation circuit 10 demodulates the received monitor signal. The demodulated monitor signal is sent to the second control circuit 27. The filter F is connected between the remote operation side antenna unit 29 and the second control circuit 27. This filter F has a frequency fThreeHowever, the energy supply signal and control signal having a frequency different from that of the monitor signal are not passed.
[0049]
In the above-described embodiment, the energy supply signal transmission unit 4, the control signal transmission unit 8, and the monitor signal reception unit 11 are integrally formed. However, the energy supply signal transmission unit 4 and the control signal transmission are described. Only the portion 8 may be integrally formed.
[0050]
Next, the operation of the second embodiment will be described.
When a predetermined AC voltage is applied to the AC power source 3, the frequency f is set from the remote operation side antenna unit 29 via the timing circuit 28.1The energy supply signal is transmitted. And frequency f1The energy supply signal is received by the reception loop antenna 13, converted into a direct current by the rectifier circuit 14, and sent to the power storage unit 15. The energy supply signal converted into a direct current is continuously stored in the power storage unit 15. The electric power from the power storage unit 15 is supplied as individual drive power when the first control circuit 19, the drive circuit 20, and the monitor signal generation circuit 25 are driven.
[0051]
When locking or unlocking, a command for locking or unlocking the electric lock is input from the input means 5. Specifically, a password is input to the numeric keypad on the remote operation side, or a card is inserted into the card reader. The personal identification number read by the numeric keypad or the card reader is sent to the second control circuit 27 as a lock or unlock command.
[0052]
The second control circuit 27 is input with lock / unlock information and door opening / closing information as monitor signals from the monitor signal demodulation circuit 10. When the unlocking command is input from the input means 5 while the locking / closing door monitoring signal is input, the unlocking command is output from the second control circuit 27. On the other hand, when a monitor signal other than the above is input, even if an unlocking command is input from the input means 5, the unlocking command is not output from the second control circuit 27.
[0053]
Further, when a lock command is input from the input means 5 while an unlocking / closing monitor signal is input, the lock command is output from the second control circuit 27. On the other hand, when a monitor signal other than the above is input, even if a locking command is input from the input means 5, the locking command is not output from the second control circuit 27.
[0054]
Then, the locking or unlocking command output from the second control circuit 27 is sent to the control signal generating circuit 7, and the frequency f corresponding to the command is sent from the control signal generating circuit 7.2The control signal is sent to the timing circuit 28.
[0055]
The timing circuit 28 connects the AC power source 3 and the remote operation side antenna unit 29 in a normal state. At this time, the control signal generating circuit 7 and the remote operation side antenna unit 29 are not connected. In this state, when a locking or unlocking command is output from the second control circuit 27 and a timing signal is input to the timing circuit 28, the timing circuit 28 is switched, and the control signal generating circuit 7 and the remote operation side antenna unit are switched. 29 is connected. At this time, the AC power source 3 and the remote control antenna unit 29 are not connected. At this time, the time during which the AC power supply 3 and the remote operation side antenna unit 29 are not connected is only a very short time between the transmission of the control signal and the reception of the monitor signal. Therefore, sufficient power can be stored in the power storage unit 15.
[0056]
As a result, the frequency f2The control signal is sent to the remote operation side antenna unit 29 and sent to the control signal receiving means 16 on the electric lock side.
[0057]
After operating the electric lock, the frequency f from the electric lock sideThreeIs transmitted to the monitor signal demodulating circuit 10 via the filter F. The monitor signal is received by the remote operation side antenna unit 29. The monitor signal is demodulated by the monitor signal demodulation circuit 10. At the same time, a lock / unlock display lamp (not shown) is turned on according to the state of the monitor signal.
[0058]
Therefore, according to the second embodiment, the first control circuit 19 and the drive circuit 20 use the stored power only when necessary, so that the peak power consumption when actually used can be shortened. It is possible to operate with a power supply stored with weak radio waves. In addition, since power can be supplied without wiring, this enables remote monitoring without wiring.
[0059]
Next, a third embodiment of the wiring-free electric lock of the present invention will be described. FIG. 3 is a diagram in which the receiving units 13 and 17 and the transmitting unit 26 are integrally formed on the electric lock side of the first embodiment. The remote operation side may be either the first embodiment or the second embodiment.
[0060]
In the third embodiment, on the electric lock side, the electric lock side antenna unit 30, the rectifier circuit 14, the power storage unit 15, the control signal demodulation circuit 18, the first control circuit 19, the drive circuit 20, the actuator 21, and the dead bolt 22 are provided. , A detection switch 23 and a filter F are provided.
[0061]
The electric lock side antenna unit 30 is formed by integrating the receiving units 13 and 17 and the transmission unit 26 on the electric lock side of the first embodiment. The frequency f1Energy supply signal and frequency f2Control signal and frequency fThreeTransmit the monitor signal.
[0062]
The filter F is connected between the electric lock side antenna unit 30 and the detection switch 23. This filter F has a frequency fThreeOnly the monitor signal is passed, and the energy supply signal and control signal having a frequency different from that of the monitor signal are not passed.
[0063]
The rectifier circuit 14, the power storage unit 15, the control signal demodulator circuit 18, the first control circuit 19, the drive circuit 20, the actuator 21, the dead bolt 22, and the detection switch 23 are the same as in the first embodiment. Description is omitted.
[0064]
In the above-described embodiments, the energy supply signal receiving unit 13, the control signal receiving unit 17, and the monitor signal transmitting unit 26 are integrally formed. However, the energy supply signal receiving unit 13 and the control are described. The signal receiving unit 17 alone may be integrally formed.
[0065]
Next, the operation of the third embodiment will be described.
Frequency f from remote control side1When this energy supply signal is transmitted, the energy supply signal is received by the electric lock side antenna unit 30 and sent to the rectifier circuit 14. The energy supply signal is converted into a direct current by the rectifier circuit 14 and stored in the power storage unit 15. The electric power from the power storage unit 15 is supplied as individual drive power sources when the control signal demodulation circuit 18, the first control circuit 19, and the drive circuit 20 are driven.
[0066]
Frequency f from remote control side2The control signal is received by the electric lock side antenna unit 30 and sent to the control signal demodulation circuit 18. The subsequent operation is the same as that of the first embodiment.
[0067]
The frequency f from the monitor signal generation circuit 25ThreeIs output to the electric lock side antenna unit 30 via the filter F. Then, a monitor signal is transmitted from the electric lock side antenna unit 30 to the remote operation side.
[0068]
Therefore, according to the third embodiment, since the first control circuit 19 and the drive circuit 20 use the stored electric power only when necessary, peak power consumption when actually used can be shortened. It can be operated by a power source stored with weak radio waves. In addition, since power can be supplied without wiring, this enables remote monitoring without wiring.
[0069]

[0090]
Further, when a lock command is input from the input means 5 while the unlock monitor signal is being input, the lock command is output from the second control circuit 27.

[0094]
By the way, during the above-described power storage operation, the level detection circuit 31 detects the level of the signal received by the electric lock side antenna unit 30 and sends the detection signal to the first control circuit 19. The first control circuit 19 determines the presence or absence of a control signal based on the detection signal from the level detection circuit 31. Specifically, when the detection signal input from the level detection circuit 31 is interrupted and the detection signal is input again after the time when the detection signal has stopped exceeds the set time, the electric lock side antenna unit 30 is It is determined that the control signal has been received, and the control signal demodulated by the control signal demodulation circuit 18 is captured.
