Abstract

PURPOSE:To set the unlocking time as desired by connecting a clock circuit, a program input circuit, and a central control device including memory and CPU to a common entrance machine and door terminal machines. CONSTITUTION:When the unlocking time for an electric lock 12 to be set is entered through a program input circuit 22 of a central control device 19, it is indicated in a circuit 22 and written in a memory 23 via CPU 20. When an electric lock switch 4 of any door terminal machine 1 is closed, an unlocking signal is emitted to a bus line 13 from a terminal machine CPU 2 via a communication I/F 3. Then the control device 19 enters signal into the CPU 20 through a communication I/F 21, reads the unlocking time out of the memory 23, and gives control signal to the bus line 13 via the I/F 21. Further a common entrance machine 5 takes the control signal into entrance machine 7 through a communication I/F 6, operates a transistor 8, actuates a relay 9, closes a contact 9a, and unlocks the electric lock 12 for the set time.

The present invention solves these conventional problems, and aims to provide a control device for a common entrance electric lock that allows the timer setting time to be arbitrarily set in short or long time units. That is.

Means for Solving the Problems In order to achieve the above object, the present invention provides a clock circuit for unlocking the electric lock at a common entrance at a predetermined time interval, and a clock circuit for unlocking the electric lock at a predetermined time interval. a program input circuit that sets the electric lock to be unlocked at a predetermined time and at predetermined time intervals, a memory that stores the settings set by the program input circuit, and a central processing that controls the entire system. A central control device having a device is connected to the common entrance machine and the residential unit terminal unit, and when the electric lock switch of the residential unit terminal is turned on, a control relay is operated to unlock the electric lock at the common entrance machine. This is how it was done.

Function: With the above-described configuration, the present invention sets the unlocking time of the electric lock from the program input circuit, sets the electric lock to be unlocked at a predetermined time and at predetermined time intervals, and stores this information in memory. In response to the unlock signal from the door terminal, the central processing unit of the central control unit unlocks the electric lock for the time set based on the information from the memory and the input from the clock circuit. The electric lock can be opened and closed at any time by instructing the common entrance machine to unlock the electric lock at a preset time and at a predetermined time interval.

Example Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a configuration diagram showing an embodiment of the present invention. In FIG. 1, the same or equivalent components as in FIG.

In FIG. 1, reference numeral 14 is the manager's master unit, which is the master unit C that inputs the unlocking time and automatic opening/closing time of the electric lock 12.

and a display section 18 for displaying operation keys.

19 is a medium heat control device, and this central control device 19 is
A central processing unit (hereinafter referred to as CPU) 20 that controls the entire system, a communication interface 21, and an electric lock 1
Program input circuit 22 for inputting setting contents related to 2.
, a memory 23 for storing setting information, and a clock circuit 24.

Next, the operation of the above embodiment will be explained.

When the system is started up, the program input circuit 22 of the central control device 19 is used to control the electric lock 12 in units of seconds or minutes, for example.
input a set time for unlocking the electric lock 12, or input a set time for automatically opening and closing the electric lock 12 at a predetermined time.

The setting contents of this time and time are stored in the program input circuit 22.
The information is displayed on the display unit and confirmed, and is also written and stored in the memory 23 via the CPU 20. The system operates in this state, and the electric lock switch 4 of the dwelling unit terminal 1
By closing the terminal, an unlock signal is output from the terminal CPU 2 to the pass line 13 via the communication interface 3.

The central control unit 19 transmits the unlock signal from the pass line 13 to the CPtJ207 through the communication interface 21.
・ ・ The unlocking time of the electric lock 12 is stored in the memory 23 along with the input time.
, and outputs a control signal to the pass line 13 through the communication interface 21 to unlock the electric lock 12 for that time.

The common entrance unit 5 outputs the /C control signal to the pass line 3 and sends it to the entrance unit CPU via the communication interface 6.
7, operate the transistor 8 for the specified time, excite the control relay 9, and close the contact 9a.
The electric lock 12 is unlocked only for a set time.

Next, a case will be described in which the electric lock 2 is to be unlocked for a predetermined time at a set time.

The CPU 20 outputs an electric lock opening signal to the pass line 13 when the time of the clock circuit 24 being monitored reaches the set time.

The common entrance machine 5 is activated by the entrance machine CPU by the above-mentioned electric lock release signal.
Control relay 9 is activated by operating transistor 8 via 7.
energizes and closes contact 9a. As a result, the electric lock 12 remains unlocked, and the entrance door becomes unlocked, allowing people to freely enter and exit from the entrance.

Then, when the set time comes, the central controller 19
The CPU 20 outputs an electric lock closing signal to the pass line 13. Therefore, the communal entrance device 5 deactivates the transistor 8 via the entrance device CPU 7 in response to the electric lock closing signal, de-energizes the control relay 9, opens the contact 9a, and restores the electric lock 12 to its original state. Return to closed state.

In this way, according to the present embodiment, the unlocking time of the electric lock 12 can be set by the program input circuit 22 in a desired time unit of seconds or minutes according to the user's request.
The clock function automatically locks the electric lock 1 at a specific time according to the contents stored in the memory 23 of the central control unit 19.
2 can be kept open.

Next, instead of the program input circuit 220, the administrator main unit 14
The case where the dial key 17 is used will be explained.

The manager main unit 14 of the apartment complex system usually uses a dial key 14 and its operating instructions to call the apartment complex.
' The program input circuit 22 of the dial key 17 of the central control unit 19 is equipped with a display unit 18 that displays the status.
The unlocking time and automatic opening/closing time of the electric lock 12 are input from the dial key 17 of the manager's master device 14 without using the key.

Based on this input, the base unit CPU 15 displays the input content on the display unit 18 and outputs a setting input signal to the pass line 13 through the communication interface 16.

On the other hand, in the central control unit 19, this setting input signal is input to the CPU 20 via the communication interface 21 and stored in the memory 23.

In this way, by sending the setting input signal to the central controller 19 via the pass line 13, control information can be input using the dial keys 17 of the manager base unit 14, and a special program input circuit is used. This has the effect that it does not need to be provided.

In the case of an apartment complex with multiple common entrance machines, if the address of the common entrance machine is stored in memory, it can be easily used in a large-scale apartment complex system.

10.＼-7 Effects of the Invention As is clear from the above embodiments, the present invention provides a central control unit with a clock circuit, a memory, a program input circuit, and a central processing unit, thereby reducing the unlocking time of an electric lock. This has the effect of allowing settings to be made in any time unit and allowing the electric lock to be opened and closed automatically at any time.
