Abstract

PURPOSE:To suppress the troubles caused by the treatment given to the abnormality produced at storage of a passing control system by correcting a zone recorded before a system down into a passed zone based on the personal collation result only. CONSTITUTION:When a card reader 2a performs the open control of an entrance/exit door 1 with only the collation of the ID code of an ID code 4a at system down of a host computer 5a, the reader 2a leaves the system down record on the read card 4a. Then an unlock signal transmission command is sent to the reader 2a based on only the personal collation result of the ID code when the system downrecord is received from the reader 2a together with the ID code at system restoration of the computer 5a. Then the recorded zone where a passing requester precedently entered and left is updated after the requester entered and left without performing a zone check to decide whether or not a passing request is given from the zone where the requester entered and left precedently. As a result, a passing control operation set before the system down can be restored in a short time.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a traffic control system, and in particular to a system that smoothly transitions to normal traffic control when the system is restored due to a system failure of a host computer that supervises the system. be.

[Conventional technology]

FIG. 3 is a system configuration diagram of a traffic control system to which a conventional access control system is applied.

In the figure, (1) is a traffic control door installed at the entrance to the specified management area, and an electric lock that is unlocked according to an unlock signal output from a card reader (2b) placed near the traffic control door. (3) is provided. (4b) is an ID cart carried by a person requesting passage to a specific management area, which causes a card reader (2b) to read an Il) code and output an unlock signal when requesting passage. (5b) is read with the card reader (2b) and checks the ID code,
It determines whether the person is a legitimate person requesting passage, outputs an unlock signal to the traffic control m (1) side according to the determination result, and displays the abnormality determination result on the CRT display (6), thereby controlling traffic and traffic management. This is the main computer that does this.

Next, the operation of the conventional system according to the above configuration will be explained with reference to the flowchart shown in FIG.

Normally, when the card reader (2b) receives the ID code from the ID card (4b) (S-40), it determines that the transmission line and main computer are alive and sends the I[) code to the main computer (5b). Transmit (S-41) ~ (S-
43). The main computer (5b) retrieves the personal data corresponding to the ID code stored in the memory fs-4
4) Check personal information such as registration number, expiration date, and qualifications (S-45). Next, check whether the passerby passing through the traffic control door (1) has passed from the correct area (S-46), and if it is correct, issue an unlock command to the traffic control door (1) (S-47). (S-51)). next,
After the passerby passes through traffic control m(1), the previous area of personal data that the passerby passed through is updated to the area after passing through fs-48).

In addition, if there is an error in determining personal data and passing from the correct area in (S-45) and (S-46), an abnormality will be displayed on the CRT display (6) (S-49). , passersby cannot pass through traffic control m(1).

By the way, when the card reader (2b) receives the ID code from the power source (4b) and determines that the transmission line and main computer are alive, if it determines that the system is down (s-so), the card reader Since the reader (2b) cannot communicate with the main computer (5), it unlocks the traffic control door (1) without performing the traffic check described above (S-51).

[Problem to be solved by the invention]

In the conventional system, traffic is controlled at the toll SA door as described above, and the card reader (2b) and main calculator (5b)
If the transmission line between the two and the main computer (5b) go down, the card reader (2b) will send a large number of passersby tolls without toll checks while the system is down.
Since the person is allowed to pass through the area to each area, the area information of each individual stored in the main computer (5b) is not changed regardless of the movement of the area. Therefore, when the transmission line and the main computer are restored, the area for which a traffic request is made is different from the recorded area, and there are many cases where traffic checks are made in the wrong area, such as when a traffic request is not made from a legitimate area, and abnormalities occur. There was a problem in that security was confused in order to deal with the outbreak.

This invention was made to solve the above-mentioned problems, and after the system is restored due to a system failure of the transmission line and the main computer, the personal data stored in the main computer can be quickly accessed from the retention area and traffic. The purpose is to obtain a traffic control system that can correctly control traffic by matching the actual areas of people.

[Means to solve the problem]

The traffic control system according to the present invention includes a card reader that is installed near the entrance/exit door of a specific management area and reads an ID code from a 10 card of a person requesting passage to the specific management area;
The ID code read out above is manually used to determine whether the user is an authorized pass requester and is making a pass request from the recorded area, and when each requirement is met, an unlock command is issued to the above entrance/exit door. In a traffic control system equipped with a host computer that transmits and updates the area record, the card reader is read as a means for outputting an unlock signal to an entrance/exit door according to a 10-code verification result when the system of the host computer goes down. and a means for recording system downtime on the ID card, and sends an unlocking command to the above-mentioned host computer after determining that the person is an authorized pass requester according to the ID code transferred from the card reader at the time of system restoration and the system down record. and means for updating the area record to the area after passing.

[Effect]

According to this invention, when the system of a host computer goes down,
Card reader <10 When controlling the opening of the entrance/exit door only by checking the ID code of the card, the card reader leaves a system down record on the ID card read, and then when the system of the host computer is restored, the card reader sends the ID code. At the same time, if a system data entry record is transferred, an unlock signal transmission command is sent to the card reader based only on the result of personal verification at the ID court, without checking the area to see if a request to pass has been made from the area where the user previously entered or exited. After a person who requests access enters or leaves the system, by updating the previously recorded entry/exit area in that entry/exit area, the traffic control operation before the system failure can be restored in a short time.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure is a configuration diagram of the traffic control system in this embodiment. In the figure, the same reference numerals as in FIG. 4 indicate the same or equivalent parts. In the figure, (2a) is a card reader in this embodiment, which can read and write the local operation number with the ID card (4a) in this embodiment. (5a
) is the main computer in this embodiment.

Next, based on the above configuration, the operation of this embodiment will be explained according to the flowchart of FIG.

First, when it is determined that the transmission line or the main computer (5a) is system down ((S-41)).

(S-42), (S-50)), the cart reader (2a) transmits and stores a local operation signal to the ID card (4a) (S-50a), and the card reader (4)
In a), an unlocking signal is output to the electric lock (3) of the traffic control door (1), and the person requesting passage is allowed to enter and exit the specified controlled area.

Next, when it is determined that the transmission line and the main computer (5a) are alive and the system is restored ((S-411
, (S-42)), the main computer (5a) receives the 10 code and local operation number received by the cart reader (2a). It is not checked whether a request for passage has been made at (S-44). If the personal data is correct, an unlock signal is sent to the card reader (2a) and the traffic control ff1l (1) is released (S-47).

Next, the retention area of the personal data stored in the memory, which indicates which area the traffic requester entered and exited in before the system went down, is corrected to the correct area after the actual traffic control W (lb). S-48a) [Effect of the invention] As described above, system failures of the transmission line and host computer are stored in the card, and when the card is used to pass, the area check is passed once and recorded before the system goes down. By correcting the areas that have been passed through only based on the personal verification results, when the system is restored, troubles caused by checking the wrong area and dealing with abnormalities due to discrepancies in the area can be suppressed, and highly reliable traffic control can be achieved. It has the effect of providing a system.
