Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric lock controller characterized by a method of displaying the status of an electric lock.

Prior Art Conventionally, this type of controller has been designed as shown in FIG.

In FIG. 2, 1 is an electric lock controller installed in the house, and 2 is a so-called electric lock that can be electrically locked and unlocked. 3 is a lock/unlock button; press it once to lock it, press it again to unlock it, and each time you press it, the lock/unlock button repeats. Locked here means that the door cannot be opened, and unlocked means that the door can be opened and closed freely. Reference numeral 4 is an indicator indicating whether the door is locked or unlocked. Reference numeral 5 denotes an unlocking mode changeover switch, which can be set to either "normal" or "automatic locking". This "normal" refers to the unlocked state where the door can be opened and closed freely, as described above, and "automatic lock" refers to the unlocked state where the door can be opened and closed freely. This means that the door can only be opened once per day, and will automatically lock when the door is closed after being opened. Naturally, the door will be automatically locked if it is not opened within the set time. This "automatic locking" function is often used in electric locks for common entrances in apartment complexes. When a visitor comes, the door is checked with a television camera to confirm the visitor's face, and if there is no problem, the door is unlocked and the visitor opens the door to enter.Then, when the door is closed, it is automatically locked to prevent unauthorized persons from entering. .

Problems to be Solved by the Invention However, in conventional electric lock controllers, the unlocked state when "normal" is selected with the unlocking mode changeover switch 5 and the unlocked state when "automatic lock" is selected are different. Since the locked state was distinguished by the selected position of the unlock mode changeover switch 5, visibility was low.

Along with this, there are inconveniences such as forgetting to lock the key because it is mistakenly assumed to be unlocked in automatic lock mode even though it is unlocked in normal mode, or vice versa. Despite this, there were inconveniences such as the lock being mistakenly assumed to be in the unlocked state in normal mode and being locked out of the building.

The present invention solves the above conventional problems, and aims to provide an electric lock controller that can clearly distinguish and display the unlocked state in normal mode and the unlocked state in automatic lock mode.

Means for Solving the Problems In order to solve the above conventional problems, the present invention provides a driving means for locking and unlocking an electric lock, and monitoring the locked/unlocked state of the electric lock and the open/closed state of the door. A monitoring means, a locked state in which the door cannot be opened, a first unlocked state in which the door can be opened and closed freely, the door is unlocked for a preset time, and the door is only opened and closed once during this unlocked time. input means for selecting three types of states including a second unlocked state that is possible only in the first unlocked state; a display means for distinguishing and displaying the locked state and the first unlocked state; and a control means for alternately controlling the display corresponding to the locked state and the first unlocked state of the display means when the second unlocked state is selected by the input means.

Effects According to the present invention, with the above configuration, the unlocked state in the normal mode and the unlocked state in the automatic locking mode can be clearly distinguished and displayed on the display means, and the visibility is high, so the two unlocked states can be displayed. It is possible to prevent mutual misunderstanding.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an electric circuit diagram showing an electric lock and its controller. Types of electric locks include the instant energization type, which locks and unlocks by repeating instantaneous energization, the motor type, which uses a motor to insert and remove the dead bolt, and the unlocking type, which unlocks when energized and locks when the energization is stopped. However, in this embodiment, a type that unlocks when energized will be used.

Reference numeral 6 is an electric lock, and a DC solenoid 7 is provided so that it is unlocked when energized and locked when de-energized.
and a lock signal contact 8 that closes when the lock is locked.
It is composed of a door closing signal contact 9 that closes when the door is closed. Reference numeral 10 denotes an electric lock controller, which is composed of driving means, monitoring means, input means, display means, and control means, which will be explained below.

11 is a relay 14 consisting of contacts 12 and winding 13
and a transistor 15 that drives this relay 14.
and a resistor 16, which is a driving means for driving the electric lock 6 to lock and unlock. By turning on the transistor 15 through the resistor 16, the winding 13 of the relay 14 whose one end is connected to the positive terminal Vcc of the DC power supply 19 is energized, the contact 12 is closed, and as a result, the DC solenoid 7 of the electric lock 6 The DC power supply 19 is connected to the door, the door is unlocked, and the door can be opened and closed freely.

Conversely, if transistor 15 turns OFF, contact 1
2 is opened, and the electric lock 6 is locked, making it impossible to open the door. 20 is an input means for selecting locking/unlocking, which consists of a normally open contact 21, one end of which is connected to a DC power source 19;
The other end is connected to a control means to be described later. In this embodiment, the input means 20 is an inverted input type in which one press is used to lock the lock, and another press is used to unlock the lock, but the input means 20 may be provided separately for locking and unlocking. 22 is a monitoring means, which includes transistors 23 and 24, and a resistor 2 whose one end is connected to Vcc and the other end is connected to the base of each of the transistors 23 and 24.
5, 26. One end of the locking signal contact 8 of the electric lock 6 is connected to the base of the transistor 23, so when the electric lock 6 is locked, that is, when the locking signal contact 8 is closed, the transistor 23 is turned off to lock the electric lock. I know that there is. Also, the door closing signal contact 9 is a transistor 24
Since the gate is connected to the base of the gate, when the door is closed, it can be recognized by turning off the transistor 24. 27 is a control means, and an output end 27a for controlling the drive means 11 that drives the electric lock 6;
A first input terminal 27b inputs whether the normally open contact 21 of the input means 20 is pressed, a second input terminal 27c determines whether the electric lock 6 is locked or unlocked, and a second input terminal 27c inputs whether the normally open contact 21 of the input means 20 is pressed. It has a third input terminal 27d for checking whether the LED is open or closed, and second and third input terminals 27e and 27f for lighting the LED. When unlocking the electric lock 6, the output terminal 27a is set to "High" and the transistor 15
is set to "ON" to activate the relay 14 and energize the DC solenoid 7 to unlock it. To lock the door, conversely, turn the output terminal 27a to "LOW".

The logic of the first input terminal 27b is "LOW" when the normally open contact 21 is pressed, and "HIGH" when it is not pressed. The logic of the second input terminal 27c is "High" since the lock signal contact 8 is closed and the transistor 23 is "OFF" when the door is locked, and "LOW" when the door is unlocked. Become. The logic of the third input terminal 27d is that when the door is closed, the door closing signal contact 9 is closed and the transistor 24
is ``OFF'', so it is ``High'', and conversely, when the door is open, it is ``LOW''. Here, control means 2
7, when inputted from the input means 20, when the second input terminal 27c is "High", ie, locked, it is recognized as an unlocking command, and when it is "LOW", ie, unlocked, it is recognized as a locking command. When it recognizes the locking command, it outputs "LOW" to the output terminal 27a. When it is recognized as an unlock command, the input time, that is, the time when the second input terminal 27b is "LOW" is measured, and if that time is within a predetermined time, it is recognized as an unlock command in the normal mode, and the output terminal 27a is output as "LOW". "High" is output. If it is longer than the predetermined time, it is recognized as a command to cancel the automatic locking mode, and "High" is output to the output terminal 27a, and the third input terminal 27d changes from "High" to "LOW", that is, the door opens and then "High". ” and outputs “LOW” to the output terminal 27a. However, during the preset time (approximately 5 to 10 seconds) the third
When the input terminal 27d does not change from "High" to "LOW", "LOW" is output to the output terminal 27a. 30 is a display means for distinguishing and displaying each state of the electric lock, and includes light emitting elements 31 and 32 (hereinafter referred to as
(LED), resistors 33, 34, 37, 38, and a transistor 35. Light emitting element 3
A single two-color light emitting element may be used instead of 1 and 32.

Next, control of the display means 30 will be explained.

When the electric lock is locked, the output terminal 27
Set e to “LOW” and turn transistor 31 “ON”
Then, the LED 32 is turned on, and the output terminal 27f is set to "High", and the transistor 35 is turned "OFF".
By turning off the LED 36, it is indicated that the electric lock is in the locked state. When the electric lock is unlocked in normal mode, the output terminal 27e is set to "High" and the transistor 31 is turned "OFF".
The LED 32 is turned off, the output terminal 27f is set to "LOW", the transistor 35 is turned "ON", and the LED
36 indicates that the electric lock is in the unlocked state in the normal mode. When the electric lock is unlocked in automatic lock mode, output terminal 2
7e and 27f alternately output "High", transistors 31 and 35 are alternately turned "ON",
By lighting up the LEDs 32 and 36 alternately, it is indicated that the electric lock is in the automatic locking mode and in the unlocked state. When the door is automatically locked from the unlocked state in the automatic locking mode, the control means 27 controls the display means 30 to display the locked state.

Effects of the Invention The electric lock controller of the present invention has the above-described configuration, and has a locked state in which the door cannot be opened, an unlocked state in the normal mode in which the door can be freely opened and closed, and an automatic locking mode in which the door can be opened and closed only once. The unlocked status of each can be clearly distinguished and displayed with high visibility. Therefore, since it is possible to instantly and accurately grasp the state in which the electric lock is, it is possible to prevent misunderstandings between the unlocked state in normal mode and the unlocked state in automatic lock mode, which may occur due to misidentification. Harmful effects can be eliminated. In addition, when locking and unlocking an electric lock, it is possible to easily and accurately grasp the condition of the electric lock before operation and after operation, so that reliable operation can be achieved. And the effect is great.
