DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a card lock device applied to card-type electronic locks installed in a plurality of rooms in one building.

[Prior art and its disadvantages] In principle, with conventional card-type electronic locks, the door can be opened from the indoor side by rotating the door knob at any time, but from the outdoor side, a predetermined card must be read by a card reader. Then, the card information verification means of the control device connected after the card reader compares and verifies the information read from the card and the unlocking permission information stored in advance to determine whether they match or not. In this case, the door knob can be rotated by giving an unlocking signal to the locking mechanism and causing the locking mechanism to perform an unlocking operation.

By the way, having a card reader read each card at times when employees frequently enter and leave the room, such as when they are dispatched to work or when they leave work, is extremely complicated and impedes smooth entry and exit. Therefore, during times when entering and exiting the room is frequent, the door is kept unlocked at all times without reading the card, and you can enter the room from outside by simply turning the door knob. It is requested that this be set.

Conventionally, a control mode selection section was provided in the lock device of each room in the building, and free time was started by pressing the free time mode setting key, and free time was started by pressing the normal monitoring mode setting key. The timer was released and normal control based on card information verification was performed.

Therefore, it is necessary to start and cancel free time each time by key operation, which makes the operation very complicated.
This was a problem in practice.

Connect all locking devices in one building with a central device,
Even when centrally managing and controlling rooms using the central device, if the free time of each room is different, it is not easy to start and cancel free time for each room individually.

[Technical Section II to be Solved] The problem to be solved by this invention is that when different free times are set for card lock devices provided in a large number of rooms, it is difficult to set different free time starts and times in each room.

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

As shown in FIG. 3, the card lock device according to the present invention is installed in each room where entry is restricted by a central bag of 1 mA and a card-type electronic lock, and is a terminal device connected online to the central device A. It is composed of B, , B2 to Bh.

Central device The central device A, as shown in FIG. 1, includes input devices rI1i,
It has a control device 2 and a transmission device 3.

The input device 1 is a keyboard with full keys, or as described below, inputs a room number (or a predetermined number for a terminal device installed in the room), a start time and end time of free time, and an execution command. It consists of the minimum necessary keys consisting of digital switches.

The transmission device 3 transmits information of predetermined contents, that is, a terminal code specifying a destination and a free time start signal, based on the output from the free time start signal output means V125 or the free time end signal output means 26 of the control device 2. Alternatively, a free time end signal is sent to each terminal device.

The control device 2 includes a free time writing means 2i, a free time table 22, a clock means 23, a table lookup means 24, a free time start signal output means 25, and a free time end signal output means 26. This control device can be configured using a microcomputer.

The basic configuration and operation of each constituent means of this control device 2 will be explained.

Based on the room number, free time start time, and free time end time input from the input device 1, the free time writer Vi21 stores the room number in the free time table in correspondence with each time.

The free time table 22 stores the free time start time and free time end time given by the free time writing means, and the room number to which each time is applied, in association with each other.

The table lookup means 24 determines whether the free time start time or end time of the free time table 22 matches or does not match based on the current time signal output from the clock means 23, and the room corresponding to the matched time. Read and output the number. If the matched time is the free time start time, the read room number is sent to the free time start signal output means 25, and if the matched time is the free time end time, the read room number is sent to the free time end signal. The signals are outputted to the output means 26, respectively.

The free time start signal output means 25 includes the table and
Based on the output from the lookup means 24, a free time start signal and a room number read out corresponding to the free time start time are output to the transmission device 3.

Furthermore, the free time end signal output means 26 outputs the free time end signal and the room number read corresponding to the free time end time to the transmission device 3 based on the output from the table lookup means 24. do.

FIG. 4 is a block diagram showing an embodiment in which the central device A is configured using a microcomputer.

The microcomputer that constitutes the control device 1f2 is C
ROM2b, RAM2c and I10 boat 2 in PU2a
The computer has a basic configuration in which d is connected, and is further provided with a buffer memory 2e and a clock mechanism 2f for temporarily storing information inputted from a keyboard 1 as an example of an input device. A keyboard i, a transmission device 3, and a clock mechanism 2f are connected to the I10 boat 2d via a buffer memory.

The CPU 2a decodes and processes signals input from each section via the I10 port 2c, and outputs control number 13 necessary for each section.

The ROM 2b stores basic programs necessary for the operation of the CPU 2a. One of these basic programs is related to the free time setting for the keyboard 1, and the other is to look up the free time table based on the time signal output from the clock mechanism 2f, and set the free time. If there is free time, information corresponding to it is transmitted to the terminal device.

The clock mechanism 2f is referenced by the CPU 2a every predetermined period of time, for example, every 5 or 10 minutes, and the CPU gives the current reference time to the table lookup means 24 to look up the free time table 22. let

The above control operations are executed according to predetermined programs based on commands input from the keyboard 1 or based on time signals input from the clock mechanism 2f, and necessary control signals are given to each part.

The operating procedure in the central device is shown in the flowcharts of FIGS. 5 and 7.

Figure 5 shows the operating procedure when setting free time.When a free time setting command is input from keyboard 1,
Start running the program for free time setting.

First, input the free time start time and the room number to which this applies (room number), then the free time end time and the room number to which this applies, and then execute after inputting each information. As the key is pressed, these pieces of information are stored in the buffer memory (steps 1 to 8. Hereinafter, a step is represented by p).
For room numbers that have a common start time or end time, you can input multiple common room numbers after inputting the time (R3, pt), and press the execution key after inputting (ps), free time It is determined that all the information necessary for the settings has been entered, and then the free time writing means 21 writes the free time start time, the room number to which it applies, and the free time table 22 configured by the RAM 2c. The free time end time and the room number to which it is applied are stored in correspondence, and the contents of the time table are created (Plo).

Table 1 shows an example of the stored contents of the time table.

The table above shows the free time shared by room numbers R1 and R2.
That is, from 8:20 to 8:40 and from 16:02.
From 0 to 16:40, room numbers R1 and R7 have common free time, that is, from 8:50 to 9:10, and from 16:50 to 17:10, room number R6
and R1□ have common free time, that is, from 9:20 to 9:40 and from 17:20 to 17:40, and room number RIO has free time from 8:50 to 17:10. An example is shown when the time is used.

FIG. 6 shows the operating procedure during table lookup.

The execution of the program starts at the same time as the power is turned on to the central unit, and the table lookup means 24 of the CPtJ2a performs the following steps.
Refer to the current time output by the clock mechanism 2f every time a predetermined time elapses, p1x+p! 2) Look up the free time table 22 based on the time signal at that time R13
), it is checked whether there is time information that matches the time signal (R14).

If there is matching time information, it is determined based on the storage area whether the time is the free time start time or end time (R18>, if it is the start time, the table lookup means 24 of the CPU The room number read out is output to the free time start signal output means 25 (p
la, ptT), based on this, the free time start signal output means 25 outputs the free time start signal and the room number as I1.
The data is sequentially output to the transmission device 3 via the 0 port 2d in correspondence with each room number. The transmission device 3 sends a free time start signal together with the terminal code to the terminal device designated based on the input room number.

Every time you output data corresponding to one room number, check whether the transmission corresponding to all room numbers has finished or not (pta)
, if it is unfinished, sends data corresponding to the next room number (
R19), repeating until the transmission corresponding to all the read room numbers is completed.

In this way, the transmission device 3 sends out a free time start signal corresponding to each room number input from the control device 2.

If it is determined that the matched time information is the end time (P2°), the table lookup means 24 outputs the room number read from the table to the free time end signal output means 26. Based on this, the free time end signal output means 26 outputs the free time end signal and each room number to the transmission device 3 via the I10 boat 2d (
pxs), based on this, the transmission device sends an end signal to all the terminal devices to which the common free time end time is applied (P22 + P23) also has a similar configuration as shown in FIG. That is, 4 is a known card reader that reads information recorded on a magnetic card or the like. Reference numeral 5 denotes a detection switch provided at the opening/closing portion of the door, which detects the opening/closing state of the door and outputs an opening/closing detection signal. 6 uses an electric lock! 2t1! The door is normally locked, but upon receiving an unlock signal from the lock control means 73 of the control device 7, the door is unlocked. The transmission device 8 is the central device A
If the terminal code sent from the terminal code is the own terminal code, the free time start signal or end signal sent is received and inputted to the control device 7.

The control device 7 includes a card information verification means 7i, a lock state determination means 72, a lock control means 73, and a free time control means 74. This control device can be configured using a microcomputer.

The basic structure and operation of each constituent means of this control device f7 will be explained.

The card information matching means 71 determines whether the card information read by the card reader 4 matches or does not match the unlocking permission information stored in advance, and outputs a validity determination signal when they match. The lock state determination means 72 determines whether the lock mechanism 6 is locked or unlocked and outputs a determination signal corresponding to each state to the lock control means 73. Based on the output signal from the collation means 7i and the lock state determination means 72, an unlocking signal for unlocking the lock 81 structure 6 is output.

When the free time start signal is input from the transmission device 8, the free time control means 74 stores the free time until the free time end signal is input thereafter.
The lock control means 73 is outputted to continuously output an unlock signal. Further, when a free time end signal is input from the transmission device, the memory of the free time is canceled and the lock control means 7
Stop output to 3.

As a result, the lock control means stops outputting the release signal that had been continuing until then.

The control device 7 of the terminal device described above can also be configured using a microcomputer.

FIG. 7 is a block diagram showing an embodiment in which the terminal device A is configured using a microcomputer.

The microcomputer that constitutes the control device 7 is a CPU
It has a basic configuration in which a ROM 7b, a RAM 7c, and an I10 board 7d are connected to a ROM 7a, and a buffer memory 7e for temporarily storing card information read by the card reader 4 and a clock mechanism 7f.

110 baud) 7d has card reader 4, detection switch 2
, a drive circuit 6a and a solenoid 6b constituting the clock i7f and the lock mechanism 6 are connected.

The ROM 7b stores basic programs necessary for the operation of the CPU 7a and unlocking permission information for checking with card information. The CPU 7a decodes and processes signals input from each section via the I10 port 7c, and outputs necessary control signals to each section.

The clock mechanism 7f runs the CPU every time the lock mechanism 6 is unlocked.
7a, and the CPU determines whether the set time for maintaining the unlocked state has elapsed based on the reference time at this time.

A drive circuit 6a constituting the lock mechanism 6 is driven by an unlock signal outputted via the I10 port as a result of information processing by the CPU, and excites the solenoid 6b. The locking mechanism performs an unlocking operation by energizing this solenoid.

The above control operations are executed according to a program, and necessary control signals are given to each part.

The operating procedure in the terminal device is shown in the flowchart of FIG.

By starting the program execution, the free time control means 7
4 has input the free time start signal, that is, whether the free time has been set (pza
), when free time is set, after giving an unlocking signal to the locking mechanism 6 and causing the unlocking operation (p25), check whether or not a free time end signal is input, that is, free time is released. This checking continues until free time is released (Pzs). Then, when the free time is released, the lock control means gives a locking signal to the lock mechanism (pz□), and thus the lock mechanism maintains the unlocked state after the free time is set until it is released.

After locking based on free time release, step P3
．． The open/open state of the door is determined in step Pza, and if the door is in the closed state, the process returns to the first step Pza. However, if the door is in the open state, the process waits until the door is closed in step p4°, and returns to the first step when the door is in the closed state.

If free time is not set at the start of program execution, the presence or absence of card input is determined in step P28, and if there is card input, the information recorded on the card is read and stored in the buffer memory, and card verification is performed. Perform processing (P2).

Card verification and discrimination processing is performed by determining whether the card information (information read from the card) matches any of the unlocking permission information stored in advance. Includes number, ID code, validity period, etc. If the card information matches the unlocking permission information, the card is judged to be valid and the locking mechanism 6 is unlocked (p3t).On the other hand, if the card information matches the unlocking permission information, Determine that the card is incorrect, clear the contents of the buffer memory (P3□),
Returning to the first step, if free time has not been set yet, waits for the next card input.

If you unlock the lock mechanism, be sure to set a timer p.3.
), check whether the door was opened during the set time of the timer (P3 a + P3S) +1 If the door was opened within this set time, lock the lock mechanism (P3
6) If the door cannot be opened within the set time, the lock mechanism is locked (937) and the process returns to the first step.

Also, if the door is opened within the set time, step P311
After the door is locked, it is monitored whether the door is closed (P3M), and this monitoring continues until the door is closed. When performing work such as indoor cleaning or maintenance repairs,
The door is often kept open until the end of the process.

When the door is closed, it is monitored whether the door has been opened again (P39), and even if the locking mechanism is locked from the inside, the door can always be opened. Therefore, if you enter the room - times, close the door, then open the door again and leave,
The process proceeds to step Pao through steps P and s, and then returns to step pza. If you open the door from inside the room,
After confirming that the door is locked (pm), return to the first step Pza. If you want to set a new free time in a certain room or change the already set free time, the central device If you first input the room number of the room using the keyboard 1, and then input the free time start time and free time end time, the free time writing means 21 will write the free time based on the judgment of the input order. - Determines whether or not there is a setting corresponding to the same room number in the table, and if there is not (when setting a new setting), the free time information entered in money is newly registered in the free time table and the start time and end of each. (memorize the room number according to the time)
Furthermore, if free time for the same room number is already registered in the free time table, the previous registration is deleted and the newly inputted free time information is registered.

Instead of inputting the room number when setting free time, it is also possible to input the terminal code.

[Effects of the Invention] As described above, the card lock device according to the invention sets and registers the free time applied to each room at the center, and adjusts the current time to the set free time start time and end time. When the free time starts and ends, the free time start signal and end signal are automatically transmitted to the terminal device, and the terminal device controls the locking mechanism to maintain the unlocked state and stop it. Free time settings and changes for each terminal device can be easily performed from the central location.

This inventive device is very useful when each room is used by different tenants and each tenant has different free time, or when free time is shifted depending on the season.
