Abstract

PURPOSE:To prevent the occurrence of maloperation as well as make operations safer and easier when the last person goes out of room by a method in which a room-leaving switch is operated at the time of room-leaving, a card is read out within a given time period thereafter, and light-putting out and crime preventing functions are allowed to work. CONSTITUTION:When a room-leaving switch 6 is operated by the last person to leave room in the room, the output is sent out to the output unit 56 of an arithmetic processor 5. When a card is inserted into a card reader 3 set on the entrance within a given time period thereafter, it is judged by a card availability discriminator 51 and sent out along with signals from the unit 56 to a lock controller 52, a lighting controller 53, and a crime-preventing controller 54, followed by locking of an electric key 1, putting-out of an illuminator 4, and operation of an alarm 7 through an outgoing means 55. The last person who leaves room can thus pass safely on light passage to the entrance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a card lock device, that is, basically a card input type electronic lock.

[Prior Art and Its Disadvantages] Generally, when the last person leaves the room, it is necessary to turn off the power of the lighting device that had been operating up to that point and to activate the security device that had been deactivated until then.

However, conventional card lock devices are independent from the power ON/OFF control of these lighting devices and security devices. That is, conventionally, when leaving the room, the power switch for the lighting device installed inside the room was manually turned OFF, and the security switch installed outside the room was turned ON using a predetermined key.

Therefore, it takes time and effort to perform the operations when leaving the room. If the power switch is located far from the doorway, you will have to walk to the doorway in the dark after the lights are turned off.If the outside area is not bright enough, it will not be easy to operate the security switch with the key. There were drawbacks such as.

[Technical Problem to be Solved] Of course, in a card lock device, each person entering and exiting the room carries a card as the minimum necessary item. Therefore, it would be extremely convenient if the card could be used to turn off the lighting device and turn on the security device when the user finally leaves the room.

Therefore, the problem to be solved by this invention is how to configure a card lock device so that the card can be used to turn off the lighting device and turn on the security device when the user leaves the room for the last time. How is it?

[Means for Solving the Problems] The present invention solves the above-mentioned problems, and includes an electric lock provided for an entrance door, a door sensor for detecting opening/closing of the door, and a door sensor for detecting opening/closing of the door. A card lock device having a card reader provided on the outside, and an arithmetic processing unit electrically connected to the electric lock, the door sensor, the card reader, and the lighting device on the indoor side of the doorway, having the following configuration. It is characterized by

That is, (a) A push button switch is provided on the indoor side of the doorway to be operated when leaving the room.

(b) The arithmetic processing device includes an output means, a card validity determination means, a lock control means, a lighting control means, a crime prevention control means, and an alarm means.

a. The output means outputs for a predetermined period of time based on the input from the push pin switch.

b. The card validity determining means compares the data from the card reader with reference data and outputs a validity determination signal when a predetermined condition is satisfied.

C1 The lock control means outputs an unlock command signal to the electric lock based on the output from the card validity determination means when not receiving the output from the output means, and receives the output from the output means. In this case, an unlock command signal is not output to the electric lock even if an output is received from the card validity determining means.

d. The lighting control means outputs a power cutoff command to the lighting device based on a logical product of the output from the output means and the output from the card validity determination means.

e. The crime prevention control means, based on the AND of the output from the output means and the output from the card validity determination means,
The drive condition is output to the alarm means.

f. The alarm means outputs an alarm signal when a door opening detection signal is input from the door sensor when receiving a driving condition from the crime prevention control means.

"Function" If the person who is not the last to leave the room opens the door by simply turning the doorknob and leaves the room, the electric lock will be locked based on the door closing detection by the door sensor when the door is closed. In this case, locking may be performed by causing an electric lock to perform a locking operation based on the input of a locking command signal from the lock control means of the arithmetic processing unit, or by detecting the closing of the door from a door sensor without depending on the arithmetic processing unit. The electric lock may be caused to perform a locking operation directly based on the signal.

When the last person to leave the room presses a push button switch provided in the room before leaving the room, the output means of the arithmetic processing unit outputs to the lighting control means and the crime prevention control means based on the signal from the switch.

When leaving the room, you can always open the door freely and leave the room, so if the last person to leave also opens the door and leaves,
Locks when the door is closed.

If a valid card is inserted into the card reader within a predetermined time after the output means starts outputting, the card validity determination means outputs a validity determination signal.

As a result, in the lighting control means and the crime prevention control means, the output from the output means and the output from the card validity determination means respectively satisfy the logical product condition, so the lighting control means sends a power cutoff command to the lighting device in the room. The crime prevention control means outputs a drive signal to the alarm means.

Therefore, the lighting device is turned off. Further, the alarm means always monitors whether the door sensor outputs an open door detection signal, and when the drive signal is input and an open door detection signal is input, the alarm signal is e.g. The information is sent to alarm devices and security centers to perform crime prevention functions.

On the other hand, if a valid card is not inserted into the card reader within a predetermined period of time after operating the push button switch, the card validity determination means will not output to the lighting control means and security control means, and the lighting device will remain as it is. The lighting continues, and the alarm means maintains the state in which the crime prevention function is released. That is, in this case, the effect is the same as when leaving the room normally, and the operation of the push button switch is invalid.

If a valid card is inserted into the card reader after a predetermined period of time has elapsed after operating the push button switch, the output of the output means is set to 0FFL, the lighting control means is turned on to illuminate the vehicle, and the crime prevention control means is turned off. Stop monitoring. Also, unlock the door.

When the output means is not outputting and the card validity determination means outputs a validity determination signal, the lock control means outputs an unlocking command signal to the electric lock, similar to the conventional card lock device.

Therefore, a valid card holder can open the door and enter the room after having the card read by the card reader. When the door is closed after entering the room, it is locked based on the door closing detection signal.

[Example of this invention] Next, embodiments of the invention will be described based on the drawings.

As shown in FIG. 1, the card lock device according to the present invention includes an electric lock 1 provided for an entrance/exit door, and a door sensor 2 for detecting the opening/closing of the door and window, if any.
, a card reader 3 provided on the outdoor side of the doorway, and an arithmetic processing unit 5 electrically connected to the electric lock, door sensor, card reader, and lighting device 64 on the indoor side of the doorway.

Further, in order to achieve the object of the present invention, an exit switch 6 is provided on the indoor side of the doorway. This switch uses a push button switch that outputs an output every time it is pressed.

The room exit switch 6 is pressed once when the user finally leaves the room. The exit switch 6 is electrically connected to the arithmetic processing unit 5. Further, an alarm device 7 is connected to the rear stage of the arithmetic processing device.

Arithmetic processing unit! 5 is a card validity determining means 51, a lock control means 52, a lighting control means 53, and a security control means 5.
4, alarm means 55, and output means 56.

The output means 56 includes a final room exit storage section 561 and a room exit timer 562 so that the card lock device performs not only control when leaving the room, which is directly related to the problem of the present invention, but also control when entering the room. There is.

The card validity determining means 51 stores in advance the PIN number and other predetermined data of the card read by the card reader 3 in the storage unit, compares it with the registration number and other standard data, and determines that the two numbers match. The validity determination signal a is output only when the data meets a predetermined condition or when both data satisfy a predetermined condition.

The output a of the card validity determining means is stored in the final exit storage unit 56.
1 and input to gates G1 + G2 and G3.

When the logical product condition is satisfied by the inputs a and b from the final exit storage unit 561 and the card validity determination unit 51, the gate G1 operates to operate the first human-powered boat of the lighting control unit 53 and the second human-powered boat of the security control unit 54. Output each to a human-powered boat.

When the output C of the gate G1 is input to the lighting control means 53, the lighting rFIJal1 means outputs a power-on command signal d to the lighting device 4 based on this.

Furthermore, when the output C of the gate G is input to the security control means 54, the security control means stops outputting the drive signal e that had been given to the alarm means 55 based on this.

When the exit switch 6 is not pressed, its output f is input to the exit timer 562. This timer is the exit switch 6.
It starts counting based on the input from , and gives the output g to the gate C2°G3. Gate G2 is exit timer 5
If the validity determination signal a is input from the card validity determination means 51 while receiving the input from the card validity determination means 62, the logical product condition is satisfied and the output is sent to the second manual boat of the lighting control means 53. and is given to the first human-powered boat of the crime prevention control means 54.

The lighting control means 53, which has been given this output, outputs a power cutoff command signal i to the lighting device 4 based on this. The same meaning applies to a method of eliminating the output of the power-on command signal d.

Furthermore, the crime prevention control means 54, which is given the output from the game) G2, sends a drive signal e to the alarm means 55 based on the input.
give.

The gate G3 sends a signal j to the subsequent lock control means 52 only when the validity determination signal a is input from the card validity determination means 51 while not receiving the output g from the exit timer 562.
Output. However, while receiving the output g from the exit timer 562, the card validity determining means 51 does not output the signal j even if the validity determination signal a is input.

Then, the lock control means 52 outputs an unlock command signal k to the electric lock 1 when inputted from the gate G3. The electric lock 1 itself is a known one. Based on the unlocking command signal k, the latch bolt is moved back and unlocked using a solenoid, and when the door is opened and then closed again, a door position sensor, etc. It has a function to automatically lock the door based on the closed door detection signal from the door.

The alarm means 55 receives a door opening detection signal l from the door sensor 2.
If the door open detection signal l is input from the door sensor while the drive signal e is being input from the crime prevention control means 54, an alarm signal m is sent to the alarm device installed in the building. 7 and/or transmit it to a remote security center.

Next, the operation of the above configuration will be explained based on the flowcharts of FIGS. 1 and 2.

The operation of the card lock device according to the present invention differs when the user first enters the room, during normal times, and when the user finally leaves the room.

That is, when no one is in the room, the security function of this card lock device is in operation. Therefore, the first person to enter the room must first insert their card into the card reader 3.
need to be read. When the card is read, the data is given to card validity determining means 51, which determines whether it is valid or invalid. If the card is valid,
Card validity determining means 51 is game) G1, G2. G3
is output to the final exit storage unit 561.

Since the exit switch 6 cannot be pressed now, the output of the gate G3 is not inhibited, so the gate G3 gives an output j to the lock control means 52 in response to the validity determination signal a. Therefore, from the lock control means 52, electricity! Unlock command signal k to 21
, so you can open the door and enter the room.

In response to the validity determination signal a and the output of the final room exit storage section 561, the gate G1 outputs an output C, and the second
Enter into a human-powered boat. The crime prevention control means 54 does not output the drive signal e to the alarm means 55 while inputting the drive signal to the second boat. Therefore, even if the entrance door is opened, the alarm means 55 outputs the alarm signal m. do not.

The output C of the gate G1 is also input to the first manual boat of the lighting control means 53, so this input causes the lighting device 4 to
N command d is given.

Further, the security control means 54 cancels the security function until the first human-powered boat receives input again from the gate G2. That is, the output of the drive signal e to the alarm means 55 is stopped.

Therefore, from now on, even if a door such as a window is opened instead of using the door scale at the entrance/exit, no alarm signal will be output.

A person who enters the room after the above-mentioned operation by the first person who enters the room can enter the room where the lighting device is already lit by simply having the card in his/her possession read by the card reader.

In other words, if you insert a valid card into the card reader,
According to the output a of the card validity determining means 51, the result is 1"G.
3 outputs a signal j, and the lock control means 52 transmits an unlock command signal k to the electric lock based on this signal, so that the user can enter the room by opening the entrance door.

Even if the door is not kept open all the time, the electric lock is unlocked by turning the inside doorknob, so you can always leave the room freely.

The last person to leave the room is required to press the exit switch 6 provided on the indoor side of the entrance before leaving the room. In other words, it is numerically necessary for the last person to leave the room to turn off the lights in the room when leaving the room. In the card lock device according to the present invention, when leaving the room, the user presses the exit switch 6 instead of operating the conventional light switch.

When the exit switch 6 is pressed, the exit timer 562 starts.
The signal g is output to G2 and G3 for a certain period of time. Then, if you leave the room within the certain period of time and have the card reader read a valid card, the card validity determining means 51 outputs to the gates Gz and G3, so only the gate G2 satisfies the AND condition and outputs it. .

This output is input to the second human-powered boat of the lighting control means 53 and the first human-powered boat of the security control means 54. Therefore, the lighting control means 53 supplies the power supply MItIi command signal i to the lighting device 4, so that the lighting is turned off. The lights turn off when you read your card after leaving the room, allowing you to exit safely through the bright passageway to the entrance.

Further, the crime prevention control means 54 outputs a drive signal e to the alarm means 55 to activate the crime prevention IR function. Therefore, if the user forcibly opens the entrance door and enters the room without using a predetermined card, or pries open the window to enter the room, the alarm means 55 outputs an alarm signal.

In the above configuration, if the indoor air conditioner is started at the time of entering the room for the first time, and stopped at the same time at the time of leaving the room,
The output of the lighting control means 53 can be used to control the air conditioner.

According to the above embodiment, when entering the room for the first time, the lighting device is turned on after reading the card, and the security function is maintained in the deactivated state. is easy to release.

[Effects of the Invention] As described above, in the card lock device according to the present invention, the card is read by the card reader provided on the outdoor side within a predetermined time after the exit switch provided on the indoor side of the entrance is operated. When it is set, the security v1 function is activated and the lighting device is turned off. Therefore, the user can safely leave the room through the well-lit passageway leading to the entrance, and since the security function is activated after leaving the room, the security device will not malfunction due to an erroneous operation before leaving the room.
