Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric lock management system applied to a building for centrally managing electric locks locked and unlocked by operating a card reader at each of a plurality of doorways.

[0002]

2. Description of the Related Art Conventionally, a system for centrally managing electric locks installed at the entrances and exits of each room has been introduced in large-scale buildings. A control controller provided for each floor is connected to the central management computer, and each control controller is connected to a gate unit that is connected to an electric lock provided at each entrance and a card reader. And constitutes an electric lock management system.

The management computer manages the state of each electric lock, and displays the locked, unlocked, and broken states of all the electric locks it manages on a display or the like. Further, an electric lock can be designated and the electric lock can be locked or unlocked. Each control controller connected to the management computer, in a normal monitoring state, communicates with each gate unit by the polling method, and if the information returned from the gate unit is different from the previously received information,
The received information is transmitted to the management computer.

Further, when each control controller receives a control signal for locking or unlocking the electric lock from the management computer, the control controller transmits the control signal to the corresponding gate unit by the selecting method, and the gate unit unlocks the electric lock. It is controlled. Furthermore, from the management computer to each gate unit via the controller,
The ID code of the card that permits locking and unlocking of the electric lock can be registered. Each gate unit locks or unlocks the electric lock only when the ID code read from the card by the card reader is an ID code registered in advance.

FIG. 12 shows the operation at the time of ID code registration. Here, a controller and a plurality of gate units (1 to 1 connected to the controller
It shows the exchange of signals with n). In the normal monitoring state, the controller polls each gate unit, but when the management computer requests the card ID registration for the gate unit (gate unit 1 in the figure), the polling is performed. Interrupt and register for that gate unit I
The D codes are transmitted in sequence, and when the registration of the ID code is completed, the polling operation is returned to.

[0006]

However, in the above-mentioned conventional electric lock management system, as shown in FIG. 12, while the ID code is registered in the gate unit from the management computer via the control controller, as shown in FIG. Since the polling operation by the controller is interrupted, the management computer has a problem that the locked / unlocked state of the electric lock and the occurrence of a failure during that time cannot be immediately understood.

In particular, if there are many ID codes to be registered in the gate unit, for example, if there are several thousand, it will take several tens of minutes to register the ID code, and furthermore, registration of the ID codes for a plurality of gate units will continue. This would effectively stop the monitoring function of the system. Also,
Even if you try to control the electric lock from the management computer,
Similar to the above, if the ID code is being registered, it may take time until the control signal reaches the gate unit, and there is a problem that locking / unlocking of the electric lock is delayed.

The present invention has been made in view of such circumstances, and the state of the electric lock can be monitored even while the ID code of the card is being registered in the gate unit.
Another object of the present invention is to provide an electric lock management system capable of controlling the electric lock from a management computer.

[0009]

In order to achieve the above object, in the electric lock management system according to claim 1 of the present invention, each controller communicates with a management computer via a first transmission line. And a second communication means for controlling communication with each gate unit via the second transmission line, and one normal transmission buffer for accumulating information to be transmitted to each gate unit. , One or a plurality of low-speed transmission buffers provided for each of the gate units and storing information to be transmitted to each of the gate units.

In the monitoring state, the controller is in the second state.
The communication means communicates with each gate unit by the polling method, and if the received information is different from the previously received information, the first communication means transmits the information received this time to the management computer. Here, in order to prevent an increase in communication volume on the first transmission line between the management computer and the control controller, the information returned from the gate unit in response to polling is the information returned previously. And only if that information is sent to the management computer.

On the other hand, the control controller, when receiving the information from the management computer by the first communication means, if the transmission type of the information is the normal mode, accumulates it in the normal transmission buffer and transmits the information. Is in the low speed mode, the data is stored in the low speed transmission buffer corresponding to the gate unit that is the transmission destination. At the same time, the control controller normally refers to the transmission buffer, and if there is stored information, sequentially retrieves that information, and by the second communication means,
If the stored information is transmitted to the corresponding gate unit by the selecting method, and the normal transmission buffer has no accumulated information, the low-speed transmission buffer is sequentially referred to. If there is accumulated information, only the first accumulated information is extracted and the second communication is performed. By means of a selecting method, transmitting to the gate unit corresponding to the low-speed transmission buffer, and if there is no accumulated information, repeating the above series of operations of communicating with the gate unit corresponding to the low-speed transmission buffer by the polling method. Due to
Transmission is performed in the order of priority: accumulated information in the normal transmission buffer and accumulated information in each low-speed transmission buffer.

According to a second aspect of the present invention , each control controller further includes one high-speed transmission buffer for storing information to be transmitted to each gate unit. When the control controller receives the information from the management computer by the first communication means, if the transmission type of the information is the high-speed mode, the control controller stores the information in the high-speed transmission buffer and the transmission type of the information is the normal mode. For example, if the information is stored in the normal transmission buffer and the transmission type of the information is the low speed mode, the information is stored in the low speed transmission buffer corresponding to the gate unit that is the transmission destination.

At the same time, the control controller refers to the high-speed transmission buffer, and if there is stored information, sequentially retrieves the stored information and transmits it to the corresponding gate unit by the second communication means by the selecting method, and the high-speed transmission is performed. If there is no accumulated information in the send buffer, the normal send buffer is referenced, and if there is accumulated information, that information is sequentially fetched,
By the second communication means, when the information is transmitted to the corresponding gate unit by the selecting method, and the stored information in the normal transmission buffer is exhausted, the low-speed transmission buffer is sequentially referred to. If there is stored information, only the first stored information is stored. Take out the second
By the communication means of (1), the above-mentioned series of operations for transmitting to the gate unit corresponding to the low-speed transmission buffer by the selecting method and communicating with the gate unit corresponding to the low-speed transmission buffer by the polling method if there is no accumulated information. By repeating the above, transmission is performed in the order of the priority of the accumulated information of the high-speed transmission buffer, the accumulated information of the normal transmission buffer, and the accumulated information of each low-speed transmission buffer.

According to a third aspect of the present invention, the information transmitted and received by each controller in the first or second aspect is specifically shown, and each controller receives the information from each gate unit by the second communication means. The information is status information and failure information of the electric lock and the card reader, and the information received from the management computer by the first communication means is
It is control information of the electric lock, to which the transmission type is added, and ID code information of the card that permits the operation of the card reader.

That is, here, in order to prevent an increase in communication volume in the first transmission line L1 between the management computer 1 and the control controller 2, the information returned from the gate unit 3 in response to polling is Only if it is different from the information that was previously returned,
The information is transmitted to the management computer 1.

Further, the management computer 1 transmits a control signal for locking or unlocking the electric lock 4 to each control controller 2, and the control controller 2 which receives the control signal.

Only when the D code is a pre-registered ID code, the electric lock 4 is locked or unlocked.

Next, an example of the configuration of the controller 2 is shown in a block diagram in FIG. Each controller 2 includes a control unit 20 that controls each unit, a first communication unit 21 that controls communication with the management computer 1 via the first transmission line L1, and a second transmission line L2. A second communication means 22 for controlling communication with each gate unit 3 is provided, and one normal transmission buffer 23 for accumulating information to be transmitted to each gate unit 3 is provided as a buffer for accumulating information.

In the normal monitoring state, the controller 2 polls each gate unit 3, but from the management computer 1 a certain gate unit 3 is polled.
When the message of the card ID registration command is received, since the low speed mode (S) is specified as the transmission type m2 of the message, the message is stored in the low speed transmission buffer 24 and the other gate units 3
While continuing polling, register the ID code.

With this operation, the gate unit 3 is transferred from the management computer 1 via the control controller 2.
Even while the ID code is registered in, the polling operation for the other gate unit 3 of the controller 2 is not interrupted, and the management computer 1 can know the locked / unlocked state of the electric lock 4 and the occurrence of a failure. Next, another configuration of the controller is shown in a block diagram in FIG.

In addition to the configuration of the controller 2 shown in FIG. 2, this controller 2A is provided with one high-speed transmission buffer 26 for accumulating information to be transmitted to each gate unit 3, as a buffer for accumulating information. There is. In the monitoring state, the controller 2A communicates with each gate unit 3 by the polling method by the second communication means 22 as described above, and if the received information is different from the previously received information, the controller 2A receives this time. The information is accumulated in the upper transmission buffer 25, and the accumulated information is sequentially transmitted to the management computer 1 by the upper transmission means 21b of the first communication means 21.

On the other hand, the control controller 2A receives the information from the management computer 1 by the upper receiving means 21a of the first communication means 21, and if the transmission type of the information is the high speed mode, the high speed transmission buffer 26 If the transmission type of the information is in the normal mode, it is stored in the normal transmission buffer 23. If the transmission type of the information is in the low speed mode, the low speed transmission buffer 24 corresponding to the gate unit 3 as the transmission destination is stored. Accumulate in.

At the same time, the control means 20 of the control controller 2A refers to the high-speed transmission buffer 26, and if there is stored information, it sequentially retrieves that information, and the second communication means 22 applies it in a selecting method.

When there is no accumulated information in the normal transmission buffer 23, the low-speed transmission buffer 24 is referred to in sequence. If there is accumulated information, only the first accumulated information is taken out and the second communication means 22 selects. It transmits to the gate unit 3 corresponding to the low-speed transmission buffer 24 by the method, but if there is no accumulated information, it communicates with the gate unit 3 corresponding to the low-speed transmission buffer 24 by the polling method.

By repeating such a series of operations, the priority order is set to the accumulated information in the high speed transmission buffer 26, the accumulated information in the normal transmission buffer 23, and each low speed transmission buffer 2.
The transmission is performed in the order of the accumulated information of No. 4. FIG. 8 shows an example of the configuration of information transmitted from the management computer 1 to the controller 2A. The message shown is

FIG. 9 is a flowchart (300 to 306) showing the operation when the controller 2A receives information (message) from the management computer 1. When the control controller 2A receives a message from the management computer 1 (300) and the transmission type of the message is the high speed mode (F), the message is stored in the high speed transmission buffer 26 (301, 30).
2) If the transmission type of the message is the normal mode (N), the message is stored in the normal transmission buffer 23 (303, 304), and if the transmission type of the message is the low speed mode (S), The message is sent to the low-speed transmission buffer 24 corresponding to the gate unit 3 that is the transmission destination.
(305, 306).

FIG. 6 is a flow chart (400 to 413) showing the operation when the controller 2A sends information (message) to each gate unit 3. In the controller 2A, after initializing the gate unit number (400), the high speed transmission buffer 26 is referred to,
If there is accumulated information, that information is extracted and transmitted to the gate unit 3 designated as the destination (401, 40
2) After waiting for a certain period of time (413), the high-speed transmission buffer 26 is referenced again, and if there is accumulated information, that information is extracted and transmitted to the gate unit 3 designated as the transmission destination (401). , 402), and when there is no accumulated information in the high-speed transmission buffer 26, the normal transmission buffer 23 is referred to.

If there is stored information in the normal transmission buffer 23, that information is taken out, transmitted to the gate unit 3 designated as the transmission destination (403, 404), and after waiting for a fixed time (413), it is stored in the high-speed transmission buffer 26. If there is no accumulated information and there is accumulated information in the normal transmission buffer 23, the information is extracted and transmitted to the gate unit 3 designated as the transmission destination repeatedly (403, 404).
When the normal transmission buffer 23 has no accumulated information, it refers to the low-speed transmission buffer 24 corresponding to the gate unit number (405).

If the low-speed transmission buffer 24 has accumulated information, only the first accumulated information is taken out and transmitted to the gate unit 3 corresponding to the low-speed transmission buffer 24 (406), but if there is no accumulated information, polling is performed. By the way,
Gate unit 3 corresponding to the low-speed transmission buffer 24
If the information returned from the gate unit 3 is different from the previously received information, the received information is transmitted to the management computer 1 (407-40).
9).

Then, the gate unit number is incremented (410), and when the number before the increment is the last gate unit number (n), the leading gate unit number (1) is set (411, 412). After waiting for a certain period of time (413), the high-speed transmission buffer 26 is referenced, and if there is accumulated information, it transmits. If there is no accumulated information, it refers to the normal transmission buffer 23, and if there is accumulated information, it transmits and If there is no accumulated information in 23 as well, the low speed transmission buffer 24 corresponding to the gate unit number is referred to and the accumulated information is transmitted or the polling operation is performed.

As described above, the controller 2A has the information stored in the high-speed transmission buffer 26, the normal transmission buffer 23.
The accumulated information of 1) and the accumulated information of each low-speed transmission buffer 24 are transmitted to each gate unit 3 in this order. FIG. 11 shows the operation in the case of controlling the electric lock 4 during the card ID registration. Here, the exchange of signals between the control controller 2A and a plurality of (1 to n) gate units 3 connected to the control controller 2A is shown.

In the normal monitoring state, the controller 2A polls each gate unit 3, but receives a card ID registration command (IS) message for a gate unit 3 from the management computer 1. If the normal mode (N) is designated as the transmission type m2 of the message, the normal mode (N) is stored in the normal transmission buffer 23 and the ID code is registered. Further, during this time, when a message of an electric lock control command (CT) to another gate unit 3 is received from the management computer 1, if the high speed mode (F) is designated as the transmission type m2 of the message, the message Is stored in the high-speed transmission buffer 26, and the electric lock is controlled with priority over the ID code registration.

With this operation, even while the ID code is being registered in the gate unit 3 from the management computer 1 via the controller 2A, as in the conventional case,
The management computer 1 can control the locking / unlocking of the electric lock 4 without waiting for the completion of the registration of the ID code. Although the normal mode (N) is registered as the transmission type m2 of the message of the card ID registration command here, when the low speed mode (S) is designated as the transmission type m2, As described with reference to FIG. 6, the polling operation of the control controller 2 with respect to the other gate unit 3 is not interrupted. Therefore, in the management computer 1, even when the card ID is registered, the locked / unlocked state of the electric lock 4 and the failure are detected. You can see the occurrence.

[0048]

As can be understood from the above description, in the electric lock management system according to the first aspect of the present invention, the control controller polls while prioritizing the information stored in the normal transmission buffer. Since transmission is performed to each gate unit in the order of accumulated information in each low-speed transmission buffer, if the registration information of the ID code for the gate unit from the management computer is accumulated in the low-speed transmission buffer, the ID code will be stored. Even during registration, the polling operation for the other gate units of the controller is not interrupted, and the management computer can recognize the locked / unlocked state of the electric lock and the occurrence of a failure.

According to a second aspect of the present invention, the controller carries out polling, and the priority is assigned to each gate unit in the order of the accumulated information of the high speed transmission buffer, the accumulated information of the normal transmission buffer, and the accumulated information of each low speed transmission buffer. Since the transmission is performed, if the control information of the electric lock from the management computer is stored in the high-speed transmission buffer, the ID code can be registered without waiting for the completion of the registration of the ID code.
The management computer can control locking and unlocking of electric locks.

In the third aspect, the effect of the first or second aspect can be obtained in the electric lock management system for monitoring the electric lock and the card reader, and controlling the electric lock and registering the ID code of the card. .

Send to the gate unit corresponding to the send buffer, if there is no accumulated information,
By the polling method, by communicating with the gate unit corresponding to the low-speed transmission buffer, and then repeating the series of transmission operations to the gate unit until the data is accumulated in the low-speed transmission buffer corresponding to the gate unit, the priority order is set. , The information stored in the high-speed transmission buffer, the information stored in the normal transmission buffer, and the information stored in the low-speed transmission buffer are transmitted in this order. I am polling for
When a message of a card ID registration command for a gate unit is received from the management computer, the message is accumulated in the low speed transmission buffer based on the low speed mode information of the transmission type of the message, and the other gate units are polled. ID while continuing
An electric lock management system characterized by registering codes. 3. The control controller receives the information from the gate units by the second communication means, which is the status information and failure information of the electric lock and the card reader, and the first communication means. The information received from the management computer is control information of the electric lock to which a transmission type is added, and ID code information of a card permitting the operation of the card reader. Item 2. The electric lock management system according to item 2.
