Hereinafter, preferred embodiments of the present invention will be described in detail.

1 shows a configuration of a lock device according to an embodiment of the present invention.

Referring to FIG. 1, a circuit for providing a power supply voltage to be supplied to each unit will be described first.

An AC power supply voltage is applied to either input terminal pair ACIN11-ACIN12 or ACIN21-ACIN22 of the transformer TF. Accordingly, an alternating voltage of 12 volts (V) is induced in the output terminal pair of the transformer TF, and the induced alternating voltage is input to the bridge rectifying circuit BR to be converted into a direct current voltage. The first voltage stabilization circuit VS1 performs stabilization, amplification, charging, etc. as a DC voltage from the bridge rectifying circuit BR, and outputs a stable voltage of 12 volts V to its output terminal SV1. Here, since there is a high probability of occurrence of a power failure in the event of a fire, a storage battery of 12 volts V is provided inside the first voltage stabilization circuit VS1.

On the other hand, when the administrator of the lock device according to the present invention intends to use a battery, a battery of 12 volts (V) can be inserted between the battery terminal pair (+ 12V-GND2). The voltage of the inserted battery is output to the output terminal of the second voltage stabilization circuit VS2 through the second diode D2 and the second voltage stabilization circuit VS2.

Therefore, the output voltages of the first and second voltage stabilization circuits VS1 and VS2 are applied to the power supply voltage terminal VDD by the operation of the power selection switch SS, thereby enabling operation of each part. Here, the voltage display unit 17 warns with a light emitting diode when the voltage of the power supply voltage terminal VDD reaches the lower limit voltage.

Referring to FIG. 1, a lock device according to an embodiment of the present invention is a lock device installed at a door of a building to be locked or opened by a magnet switch DM or a key K1. The relay device REL1 and The switching control unit SC is included. The relay REL1 is turned on as a current flows through the excitation coil MC to apply a driving voltage to the magnet switch DM. The switching control unit SC supplies a current to the excitation coil MC of the relay REL1 when a fire signal of 24 volts V is input directly from the fire detector FS installed in the building or through a central receiver. In FIG. 1, reference numeral ES1 is a special switch, which is normally closed but is opened by the user in a special situation, thereby allowing only manual opening and closing by the key K1.

In the state where a fire does not generate | occur | produce, the positive terminal R24V of a fire signal is floating. Accordingly, no current flows through the first resistor element R1, the first diode D1, and the first zener diode Z1. In addition, no current flows to the base and emitter of the voltage adjusting circuit VRC, the second resistance element R2, and the first transistor BT1 of the switching controller SC. Accordingly, the first transistor BT1 is turned off and no current flows through the excitation coil MC of the relay REL1. Further, since the driving voltage is not applied to the magnet switch DM because the switching unit CS of the relay REL1 connects the ground terminal to the floating terminal DLF, the lock DL maintains a locked state.

On the contrary, in the state where a fire has occurred, a voltage of 24 volts V is applied to the positive terminal R24V of the fire signal for a predetermined time. Accordingly, a current flows through the first resistance element R1, the first diode D1, and the first zener diode Z1 for a predetermined time. In addition, current flows to the base and emitter of the voltage adjusting circuit VRC, the second resistance element R2, and the first transistor BT1 of the switching controller SC for a predetermined time. Accordingly, the first transistor BT1 is turned on so that a current flows in the exciting coil MC of the relay REL1 for a predetermined time. In addition, since the switching unit CS of the relay REL1 connects the ground terminal to the negative terminal DL- of the magnet switch DM, a driving voltage is applied to the magnet switch DM for a predetermined time, so that the lock DL ) Is dragged. Therefore, when a fire occurs, the lock DL is automatically opened so that people in the building can quickly evacuate out of the building.

On the other hand, the key K1 is provided with a remote controller for outputting a radio oscillation signal corresponding to any one of the predetermined first and second coded data. The user can push the main body of the key K1 into the handle to be caught. In addition, by pressing the pull-out button B1, it is possible to release the locking state in the handle and pull out the operating part out of the handle by the force of the spring. In addition, the radio oscillation signal can be output for a predetermined time by pressing the outgoing button B2. Reference numeral 31a denotes button switches for setting either one of the first and second coded data.

When the wireless oscillation signal is input from the remote controller provided in the key K1, the receiver SR inputs a control signal having the same function as the fire signal from the fire detector FS to the switching controller SC. Accordingly, the manager of the building can use the key for outputting the radio oscillation signal corresponding to the first code data, and the fire department can store the key for outputting the radio oscillation signal corresponding to the second code data. That is, if the lock DL is not automatically dragged even though a fire has occurred, the firefighter can pull the lock DL quickly and safely using the emergency key stored in the fire department.

The receiver SR may include the input unit 11, the first amplifier 12, the intermediate frequency oscillator 13, the second amplifier 14, the decoder 15, the first and second controllers 161 and 162. Include.

The radio oscillation signal from the remote controller is input to an input section 11 provided with a receiving antenna ATR and an inductance-capacitance resonant circuit. The first amplifier 12 amplifies an output signal of radio frequency (RF) from the input unit 11. The intermediate frequency oscillator 13 provided with the inductance-capacitance oscillation circuit restores the frequency of the output signal from the first amplifier 12 to the intermediate frequency (Intermediate-Frequency). The second amplifier 14 amplifies the output signal from the intermediate frequency oscillator 13. The decoder 15 equipped with a comparator detects the level of the output signal from the second amplifier 14 and generates a serial code signal corresponding to any one of the first and second code data. When the serial code signal corresponding to the first code data is input from the decoder 15, the first controller 161 transmits a control signal having the same function as the fire signal through its output diode CD1 to the switching controller SC. ). When the serial code signal corresponding to the second code data is input from the decoder 15, the second controller 162 transmits a control signal having the same function as the fire signal through its output diode CD2 to the switching controller SC. ).

FIG. 2 shows a state in which the main body of the key K1 of the lock device of FIG. 1 is retracted into the handle. As described above, the user can push the main body of the key K1 into the handle to be caught. In addition, by pressing the pull-out button B1, it is possible to release the locking state in the handle and pull out the operating part out of the handle by the force of the spring. In addition, the radio oscillation signal can be output for a predetermined time by pressing the outgoing button B2. In Fig. 2, reference numeral 31a indicates button switches for setting any one of the first and second coded data.

FIG. 3 shows a remote controller RC provided in the handle of the key K1 of the lock device of FIG. 1.

Referring to FIG. 3, the remote controller RC includes a code selector 31, an encoder 32, a radio frequency oscillator 33, and an output 34. The code selector 31 has a ground potential or 12 at each address input terminal A1, ..., A9 of the encoding element of the encoder 32 by the user operating button switches (31a in FIGS. 1 and 2). The electric potential input through the resistor R31 from the battery BA of the volt | bolt V is selectively applied. Accordingly, any one of the set first and second coded data is input as parallel data to each of the address input terminals A1, ..., A9 of the encoding element of the encoder 32. Here, the first sign data is set when the key provided with the remote controller RC is made for use by the manager of the building. Further, the second code data is set when the key provided with the remote controller RC is made for use by the fire crew of the fire department.

The encoder 32 generates code data corresponding to parallel data from the code selector 31 as a serial code signal of a first frequency belonging to a low frequency region. That is, when the ground potential is input to the trigger enable terminal TE, the encoding element of the encoder 32 generates the serial code signal of the first frequency through the data output terminal DOUT. Here, when the user presses the originating button B2, the light emitting diode LED is turned on and the ground potential is input to the trigger enable terminal TE. In addition, the first frequency of the serial code signal from the data output terminal DOUT is the resistor elements R31 and R33 and the capacitor C31 connected to the external resistor terminals RS and RTC and the external capacitor terminal CTS. It is set by the values of.

The radio frequency oscillator 33 raises the frequency of the serial code signal from the encoder 32 to the second frequency of the radio frequency band and amplifies the serial code signal. Here, the switching transistor ST reproduces and amplifies the serial code signal applied to the base at the set speed of the second frequency. The second frequency is set by the values of the capacitors C1,..., C4 and the coil L connected around the switching transistor ST. An output unit 34 composed of a transmission antenna ATT and a variable capacitor VC is connected in parallel with the radio frequency oscillator 33 to output a serial code signal from the radio frequency oscillator 33 as a radio oscillation signal. . Here, the transmitting antenna ATT is formed by a pattern on a printed circuit board.
