Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Valve 81F) The present invention provides a gate that locks and unlocks an electric lock using an IC card with a large storage capacity and excellent safety. Regarding a control device.

(Conventional technology) To ensure the safety (security) of entering the room,
The key to the door (gate) of the room is an electric lock, and specific entry conditions are set.
There is a gate control system that unlocks this electric lock and allows entry to the room only when the conditions are met.

In this gate control system, conventionally, magnetic stripe cards (hereinafter referred to as magnetic cards) have often been used. However, since the amount of information that can be stored on a magnetic card is approximately 78 characters, it is possible to store only 78 characters.
There was a limit to the amount of news.

In addition, recently, the conditions for entering a room do not necessarily mean that any employee of the same company can enter the room, but rather strict conditions may be attached. for example,
Only people from the department involved in the development and who have specific qualifications can enter the room where new development is being carried out, and entry conditions vary depending on the time of day. In some cases, the conditions are becoming more precise.

In the case of such entry conditions, conventional magnetic cards do not allow details such as departments and qualifications to be stored on the card, and restrictions on what can be written on the card are a drawback from the perspective of ensuring security.

(Problem to be solved by the invention) However, recently, ICs with large storage capacity and excellent safety have become available.
Cards have appeared. And, an IC card with a storage capacity of 64 bits has a storage capacity of about 10 bits compared to a magnetic card.
It has 0 times the storage capacity.

As described above, the IC card has a large storage capacity and can sufficiently store information such as departments and qualifications within the card, thereby making up for the drawbacks of magnetic cards. Furthermore, since data storage and retrieval of IC cards are controlled by a microprocessor inside the IC card, forgery and unauthorized use are difficult to occur, and the IC cards have a high level of confidentiality in terms of security.

The present invention has been made in view of the above circumstances, and aims to provide a gate control system that has high upstream security and can be used for multiple purposes by applying an IC card with a large storage capacity and excellent safety. The purpose is

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a gate control device that reads the memory contents of an IC card and controls the opening and closing of a door at the time of entry and exit. A reader/writer for writing information on the t! Instructions on work content, display of equipment abnormalities,
A display unit that displays messages, a transmission control circuit that controls the transmission and reception of information with the processing device, an input/output circuit that outputs operation commands to the electric lock and inputs the status of the electric lock, and a It consists of a control circuit that gives control instructions, and a storage circuit that stores the above-mentioned operation 1 display, control contents, and results.

(Function) When entering the room, the IC card holder unlocks the function key on the operation unit and then inserts the IC card into the reader/writer.The information read by the reader/writer is passed to the control circuit and stored in the memory circuit in advance. If the information read by the reader/writer matches the contents of the memory circuit, you will be prompted to enter your PIN number.If this PIN number matches the number already registered, It gives an unlocking command to the electric lock, displays it on the display circuit, and sends entry/exit times and other information to the processing device.The information sent to the processing device is used as management information for people entering and leaving the room.

(Example) Examples will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a gate control device according to the present invention.

In FIG. 1, the gate control system includes a gate control device 1, an IC card 2, a processing device 3, an electric j24,
Furthermore, the gate control device 1 includes an IC
Card reader writer 11. It is composed of an operation section 12, a display section 13, a transmission control port #114, an input/output circuit 15, a control circuit 16, a memory circuit 17, and a clock device 18.

Figure 2 is a diagram showing the flow of operations in relation to functions.
FIG. 3 is a flowchart showing the processing contents. The operation when entering a room will be explained using FIGS. 1, 2, and 3. The numbers given in FIG. 2 indicate the order.

First of all, Fl! is a place consisting of computers, etc. The device 3 transmits control information such as information on the accident card, IC card conditions, electric lock model, etc., that is, initial setting information, as entry/exit conditions for checking whether the IC card user can enter the room. and transmits it to the control circuit 16 and sets it in the table of the storage circuit 17. That is, the initial setting information is sent to the processing device 3.
From there, it is set in the memory port 1R117 of the gate control device 1 using the downline loading function.

Next, to explain the case where an IC card user uses an IC card to enter the room, in step S31, the operation section 1
2, operate the function key ``unlock'' on the touch panel etc. incorporated in 2, and then proceed to step 832.
Insert the IC card into the reader/writer 11 at ■. In step 833, the reader/writer 11 inserts the inserted I
2. Read the information stored in the C card and pass the information to the control circuit 16.

In step 834, the information input to the control port 116 and
Compare the information set at the time of initial setting and stored in the memory circuit 17, and check whether it is possible to enter the room.

If the initially set memory information and the input information from the IC card match, it is possible to enter the room.
Ask for a PIN number to confirm your identity ■, I
The C card user confirms this and inputs the PIN using the numeric keypad on the operation section 12. In step S83, the control circuit 16 inputs the PIN entered from the operation section 12 and the PIN stored in the IC card. The password is compared with the number, and if the password is correct, it is confirmed that it is the person in question, and the Sudebu S37 issues an unlocking command to the electric lock 4 via the input/output circuit 15.■, [Phase]. The electric lock 4 performs control based on this command and makes it possible to enter the room. This control result is input to the control circuit 16 through the input/output port 115, and is displayed by the control circuit 16 at step 838.
Since the IC card user has confirmed that the electric lock 4 is unlocked and can enter the room, the user opens the door (gate) and enters the room in step S39.

Then, the Stellaf S40 edits information regarding the entry of the IC card user who performed these series of operations (operated function key IC card user number, etc.), entry time read from the clock device 18, and information regarding the electric lock. Then, the information is sent to the processing device 3 via the transmission control circuit 14.If the stored information and the read information do not match in step S34, or if the password does not match in step 836, the process advances to step S41. The gate controller 1, the electric lock 4, and the door (gate) 5 are constantly monitoring whether the gate controller 1 itself, the electric lock 4, and the door (gate) 5 are operating normally. The information is transmitted to the processing device 3 via the transmission control circuit 14. Also, if an abnormality occurs for some reason, the information is transmitted to the processing device 3 and the display unit 1
3 and alarm with an alarm 0゜In combination with an electric lock that controls the door (gate) like this,
By effectively utilizing the calculation function, large storage capacity, and high security of an IC card, it is possible to ensure the safety (security) of entering a room and to control the electric lock.

In the above-described embodiment, it has been explained that the gate control circuit gives permission to enter and exit the room for those who have an IC card. However, this device also has the functions listed below.

■ Ascertaining who enters the room Management information, personnel information, qualification information, and other information for each purpose are input into the IC card possessed by the person who enters the room. The management information is information that checks whether the IC card can be used.
It is used to manage the C card itself and contains information such as the card number and expiration date. Personnel information is detailed information about the IC card holder, and includes information such as surname, first name, gender, employee number, department/department code, position name, position code, and contact information. Qualification information is information that checks the qualifications of the IC card holder.
There is information such as security class and card number.

An example of how to track the number of people entering the room is shown below.

First, personnel information of persons who can enter the room is set in the memory circuit 17 of the gate control device 1 from the processing device 3 at the time of initial setting. When the IC card 2 is inserted into the gate control device 1,
The person Ti information is read from the IC card 2, and this personnel information and the employee number, department code, and department code set in the memory circuit 17 are read.
This is a method of determining by comparing personnel information such as job title codes. This method allows for individual comparison and discrimination based on personnel information, so detailed discrimination can be made. However, since the personnel information itself is set, the capacity of the setting section of the storage circuit becomes large, and since the contents of the personnel information are directly compared, it may take time for verification.

Another example of how to grasp the number of people entering the room is shown below.

Although this overlaps with the personnel information described above, this is a method in which a security class item is provided in the qualification information, and the person entering the room is identified using this security class information. As a concrete method, as shown in Figure 4, N items for setting the security class are prepared in the memory circuit of the IC card (in the case of Figure 4 256), and for each item gender, position, department name, etc.・・・
For each IC card, 1° is set in the item corresponding to the IC card owner.

On the other hand, this type of entry condition for the gate control device 1 is set at the time of initial setting from the processing device 3. These entry conditions are set for each gate control device in correspondence with the security class items shown in FIG. For example, if there is a room that only employees with the rank of manager or above can enter, a security class as shown in FIG. 5 is set from the processing device 3 to the gate control device 1 at the time of initial setting.

Specifically, if we assume that female employees can enter the women's locker room, the security class employee/female item is I.
If it matches the C card control device, you can enter the room. Even in this case, if there is a women's changing room on each floor and people from other floors are not allowed to enter, create an item to represent each floor such as 1st floor, 2nd floor, etc. If the items on the M floor do not match, you will not be able to enter the room.

In addition, if there are many items for which security classes can be set, an item that summarizes all the items that meet each condition, that is,
Another method is to set a security class item that includes all conditions. In the above example, the method is to assign one security class of employee, female, and floor M.

In this method, the comparison and verification of the security classes in the gate control device can be performed quickly and easily because it is sufficient to verify only one security class item.

As described above, when an IC card is inserted into the reader/writer of the gate control device when entering a room, the gate control device reads the information stored inside the IC card from the IC card to understand the person entering the room. be able to.

Furthermore, since the IC card user enters the PIN number and confirms the PIN number, it is even more secure.
can be secured.

In addition, if you have a lost accident card, register the accident card number in advance during the initial settings for the gate control device, and compare and match the card number read from the IC card with the registered accident card number. , it is possible to identify accident cards that have been used illegally.

■ Information transmission for management tasks such as location management and work management The IC card user inserts the IC card 2 into the gate control device 1 and operates the operation unit 12 to input information corresponding to the purpose, i.e., dispatch, clock-out, etc. , Contents of function keys when operated on a business trip, going out, returning to work, etc., or contents of PIN code being operated to enter the room,
The employee number read from the IC card 2 and the time information read from the clock device 18 are transmitted from the gate control device 1 to the processing device 3. The processing device 3 performs the following operations based on the information sent from the gate control device 1.

Based on the time, employee number, and contents of the operated function key transmitted from each gate control device 1, the IC
Check the arrival time, leaving time, leaving time, etc. of the employee who has the card, and perform work management such as creating work schedules and calculating overtime hours.This content is the work management performed using magnetic cards. is the same as ).

On the other hand, when entering a room, the gate is opened and the IC card 2 is inserted into the gate control device 1 and the password is entered, so the processing device 3 uses the employee number transmitted from each gate control device 1 to You can see which rooms people are in. In addition, the contents of the function keys operated by the IC card user from the operation unit 12, such as dispatch, return to work, business trip, etc.
You can see the details of your outings, etc., and if you are not at the office, you can know the purpose of your outings.

In this way, the location of each person can be known, as well as where they are located or for what purpose they have gone outside the company, making it possible to manage the whereabouts of IC card users.

In addition, if there is a room where the door (gate) is kept open at all times due to the frequent coming and going of IC card users, the gate control color 1 will be installed each time a person enters the room to manage the location.
only insert the IC card 2.

As described above, by transmitting the entry information from the gate control bag 0 to the processing device, the processing device uses the I/O based on this information.
It is possible to perform management tasks such as location management and work management of C card users.

Message Display 1 FIG. 6 shows the gate control system shown in FIG. 1, which includes a gate control bag W1, an IC card 2, a processing device 3, and a terminal device 31 connected to the processing device 3. Further, the gate control device 1 has the same configuration as that in FIG. 1.

As described in the management item above, although the location management function allows you to know where each person is, it is not always possible to contact them, and it is not possible to contact people who are out of the house. In such a case, when the person you want to contact uses the gate control device, a message is displayed to the person and the content is conveyed to the person in the following manner.

The employee number and contact information of the person to be contacted are input into the processing device 3 from the terminal device of the processing device 3. Upon receiving this, the processing device 3 inputs the employee number of the person to be contacted to each gate control device 1.
Set to . When the IC card is inserted in the gate control device 1, the employee number and IC
I matched it with the employee number read from the card and it was Ren M!
If you are a person who has set the item, on the display section 13,
For example, display °°Notifications required°. Upon receiving this display, the IC card user notifies the processing device 3 of confirmation information from the operation unit 12. The processing device 3 transmits the memorized message to the gate control device 1.
The message is displayed on the display section 13 of the IC card user, and the message is conveyed to the IC card user as a message display. This method transmits information after the person you want to contact is known, so it is possible to communicate detailed information, but on the other hand, it may take time to transmit the information.

Another method for displaying messages is to determine the text (standard text) of the message in advance between the processing device 3 and the gate control device 1.

For example, 1. return to your seat.

2. Call your seat.

Decide on the text and number. When a matter to be contacted occurs, the employee number of the person who wishes to contact the processing device 3 and the number of the text of the matter to be contacted are inputted from the terminal device 31 of the processing device 3.

The processing device 3 sets the employee number of the person to be contacted and the text number of the message to each gate control device 1. When the IC card is inserted in the gate control device 1, the employee number for which notification items have been set is compared with the employee number read from the IC card, and if the person has notification items set, the display unit 13 is displayed. For example, a message indicating that there is a notice and a document containing the notice may be displayed at the same time. This method allows you to quickly display a message because you can identify the person you want to contact and also display the message, albeit a fixed phrase. Note that the fixed phrase is set in advance in the memory circuit 17 of the gate control device 1.

In other words, in cooperation with the processing device, if there is a matter to be notified to a specific IC card user, the processing device communicates the contents to each gate control device, and the specific IC card user controls the gate. When an IC card is inserted into the bag, it is determined that the IC card user is a specific IC card user based on the information on the IC card, and messages can be displayed on the display section to convey the contents.

@ Message display 2 The company name mark and the names of each department are input from the terminal device 31 of the processing device 3 to the processing device 3. The input company name mark and each department/section name are transmitted from the processing device 3 to the corresponding gate control device 1 and set in the storage circuit 17. Based on this set content, the gate control device 1 displays the company name mark on the display unit 13 when the gate control device is not operating using an IC card, or displays the company name mark in each room. Display the name of the department to which you belong and act as a guide board.

Also, notices from the company, such as ``Tomorrow is a health checkup day. '°, the contents of the notice are input to the processing device 3 from the terminal device 31 of the processing device 3. The input contents are transmitted from the processing device 3 to all the gate control devices 1 and set in the storage circuit 17.

Based on this set content, the gate control device 1 constantly displays the notification content on the display unit 13 when the gate control device is not operating using an IC card, so that employees can It is possible to thoroughly inform the public.

In other words, if a large display such as a liquid crystal display is used for the display section, in addition to displaying the operation instruction guide and operation results during the operation described above,
When not in operation, it can display information such as company information, department color display, and messages such as notifications set in the processing device.

(2) Flexible change of entry control level The memory circuit 17 of the gate control device 1 shown in FIG. 1 uses a rewritable memory, such as EEPROH.

The purposes for which buildings and rooms are used change each time a company changes its organization or layout. A room that was once a general office may become a development project room for developing highly confidential new products at the same time as an organizational change. In this case, the conditions for controlling the entry of persons entering the room will naturally become stricter, so the entry conditions of the gate control device 1 must be changed. In a conventional gate control device configured with a hardware circuit and a circuit set to one read-only memory (RO14>), it is necessary to modify the hardware, set the memory to read-only memory (110M), and replace the memory each time. Must be.

Therefore, since a rewritable memory is used in the storage circuit 17 of the gate control device 1, when the entry conditions for each layer (gate) are changed, the processing device 3 It is possible to create a new room entry condition and set its contents to each gate control device 1 using the initial setting function.

In this way, information such as room entry conditions is set from the processing device as initial setting information in the memory circuit of the gate control device, and entry checks are performed based on this information, so the information can be changed depending on the installation location and environment of the gate control device. Entry level can be changed flexibly. That is, when the purpose of the room in which the gate control device is installed changes, the entry check conditions etc. can be changed flexibly and easily by changing the initial setting information.

■ Real-time change of entry qualifications As is clear from the above explanation, the entry conditions created by the processing device can be set for each gate control device using the initial setting function, so the entry conditions etc. can be changed in real time for each gate control device. can do.

for example, 1. Change the conditions for entering the office during and outside of working hours.

2. Change entry conditions on weekdays and holidays.

3. Change the conditions for entry when there are special events.

4. When there is flL, change the entry conditions only during that time, and return to the original once the event is over.

5. When important people are present, strict entry conditions will be imposed and people from other departments will be restricted from entering the room.

6. If there is a specific work to be done, change the eligibility conditions for the person entering the room only during the working hours of that room.

By being able to easily change the entry qualification conditions in real time, flexible operations are possible.

[Effects of the Invention] As explained above, according to the present invention, various information can be stored in an IC card with a large storage capacity, and records stored in advance can be stored in an IC card.
! If the conditions match the a information, entry permission will be granted.
The configuration allows for highly secure entry management, control of electric locks, identification of persons entering the room, display of operation instruction guides and operation results on the display section I\, information display, message display from the processing equipment, It is possible to provide a gate control device that can flexibly change the entry management level, change entry qualifications in real time, etc.
