Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric lock control device for controlling a plurality of electric locks and an electric lock control module used in the electric lock control device.

[0002]

2. Description of the Related Art In an electric lock control system configured to control a plurality of electric locks, an operator operates a card reader or a ten-key pad when locking or unlocking the electric locks. When the card reader or the like is properly operated, the data input from the card reader or the like is transmitted to the electric lock control device. In the electric lock control device,
Identify the electric lock to be controlled based on the received data,
A control signal is transmitted to the specified electric lock to cause the locking or unlocking operation.

[0003]

In the conventional electric lock control device, when a card reader or the like is simultaneously operated for a plurality of electric locks, a control signal is simultaneously sent to the plurality of electric locks. Therefore, a plurality of electric locks unlock or lock at the same time. Therefore, as a power source for the electric lock,
It was necessary to have a capacity capable of operating a plurality of electric locks at the same time.

As a result, the power supply device becomes large, and when the power supply is housed in the electric lock control device, the electric lock control device also becomes large. In addition, since it is necessary to prepare a power supply with the capacity necessary to operate all the electric locks to be controlled, if there are few electric locks actually connected to the electric lock control device, an extra power supply will be provided. , Which led to higher costs.

An object of the present invention is to provide an electric lock control device capable of controlling a plurality of electric locks and reducing the capacity of the electric lock power source, and an electric lock control module used in the electric lock control device. To provide.

[0006]

To achieve the above object, the present invention provides an electric lock control module for controlling an electric lock of an electric lock control device according to a locking / unlocking control signal from the locking / unlocking control means. Have a plurality of. Each of the electric lock control modules has a control signal output means for outputting a control signal to its own electric lock, a control signal input means for receiving a locking / unlocking control signal from the locking / unlocking control means, and its own electric lock. Of the control reservation signal of the other electric lock control module, and a monitoring means for detecting the control reservation state of the other electric lock by the control reservation signal from the other electric lock control module, and its own electric lock. When the locking / unlocking control signal is input to the control signal input means, the monitoring means does not detect that the other electric lock is in the control reserved state from the monitoring means to the other electric lock control module. Control reservation signal is transmitted by the control signal output means and the control signal output means outputs a signal for controlling its own electric lock.

By the means described above, when one electric lock control module outputs a control signal to its own electric lock, another electric lock control module simultaneously outputs a control signal to another electric lock. Will disappear. Therefore, the power source of the electric lock is sufficient if it has a capacity for operating one electric lock, and the power supply device can be downsized.

Further, the electric lock control module may be provided with a priority setting means for setting the priority of the electric lock of its own. In this case, the control means, when the locking and unlocking control signal for its own electric lock is input to the control signal input means, the monitoring means does not detect that another electric lock is in the control reserved state, or Even if it is detected that the other electric lock is in the control reserved state, the control signal output means determines that the priority set by the priority setting means is higher than the detected priority of the other electric lock. A signal for controlling the electric lock is output.

In this case, when a plurality of locking / unlocking control signals are input at the same time, each electric lock sequentially performs the locking / unlocking operation according to the set priority. Even in this case, since the plurality of electric locks do not simultaneously perform the locking / unlocking operation, the power source can have a small capacity.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 is a diagram showing an internal configuration of the electric lock control device. FIG. 2 is a diagram showing a configuration of an electric lock control system that controls a plurality of electric locks.
FIG. 3 is an operation flowchart showing an operation flow of the electric lock control device.

The electric lock control system shown in FIG. 2 includes one electric lock control device 1, three electric locks 2a, 2b and 2c and three card readers 3a and 3 for controlling the locking / unlocking of electric locks.
b, 3c. These are connected to each other by a cable 4. The cable 4 has a power supply line and a signal line. In addition, the electric lock control system power supply 19
Are stored in the electric lock control device 1.

The general operation of the electric lock control system of FIG. 2 will be described. When the operator operates the card with the card reader 3 a, the card data is read and transmitted to the electric lock control device 1 via the cable 4. The electric lock control device 1 locks and unlocks the corresponding electric lock 2a based on the card data. In the system of FIG. 2, a card reader is used as the locking / unlocking control means, but other devices such as a numeric keypad can be used. Further, the power supply 19 is installed in the electric lock control device 1, but can be installed in any place.

The configuration of the electric lock control device 1 will be described with reference to FIG. The electric lock control device 1 includes the electric locks 2a, 2b, 2
electric lock control module 10a provided corresponding to c,
It has 10b and 10c. Electric lock control module 10
a, 10b and 10c are electric locks 2a, 2b, and 10b via the signal lines 43a, 43b and 43c of the cable 4, respectively.
2c is connected. In addition, each card reader 3a, 3
b and 3c are connected via a common signal line 42.
Furthermore, each electric lock control module 10a, 10b, 10
c are interconnected by reservation lines 18a, 18b, 18c.

The electric lock control modules 10a, 10
The electric lock 2 and the reservation line 18 that match the attached alphabetic characters of b and 10c are referred to as the electric lock of the electric lock control module 10 and the reservation line thereof. For example, the electric lock 2a is the electric lock of the electric lock control module 10a, and the reservation line 18a is the electric lock control module 10a.
It is a self-reservation line.

The power supply 19 is a power supply line 41 of the cable 4.
Power is supplied to the electric lock control module 10, the electric lock 2 and the card reader 3 via the. Each means constituting the electric lock control module 10 will be described. The storage means 12 is composed of a ROM / RAM and stores a program and its own address. The timer 13 measures a plurality of waiting times. Priority setting means 14
Is a dip switch and sets the priority of each electric lock control module 10.

The reservation line monitoring means 15 monitors the reservation line 1
The voltage appearing on 8 monitors whether or not the electric lock control module other than itself is in the control reserved state. Further, a control reservation signal is output to the reservation line 18 in order to notify the other electric lock control module that its own electric lock control module is in the control reservation state. The control reserved state means a state in which the electric lock control module 10 is preparing (reserving) control of the electric lock or a state in which the electric lock is actually controlled. In this embodiment, it means a state in which a predetermined voltage is applied to the reservation line 18.

The communication control means 16 communicates with the card reader 3 via the control signal line 42. The electric lock control signal output means 17 is composed of an output relay and outputs a locking / unlocking signal to its own electric lock 2 via the electric lock control signal line 43. The control means 11 comprises a CPU and its peripheral circuits and controls the electric lock control module 10 as a whole. An operation flow of the electric lock control module 10 will be described with reference to FIG.

In the following description, the electric lock control module 1 will be described.
As a representative example of the operation of 0, the operation in the case where the first electric lock control module 10a controls the locking and unlocking of the first electric lock 2a by the operation of the first card reader 3a by the operator will be described. In step 1, the locking / unlocking control signal from the card reader 3 to the electric lock 2 is the communication control means 1
It is monitored whether or not the data is received at 6. Now, when the operator operates the card with the card reader 3a and the card data is read, the card data is transmitted to each electric lock control module 10a, 10b, 10c via the signal line 42. Each electric lock control module 10a, 10
In b and 10c, this card data is sent to the communication control means 16
When it is received, the card data is collated with the self-address and the authentication code stored in the storage means 12. If they match as a result of collation, the process proceeds to step 2, and if they do not match, the process returns to step 1 to continue monitoring whether or not the locking / unlocking control signal is received.

In this description, since the card held by the operator is a card that can unlock the electric lock 2a, it is the first electric lock control module 10a that the processing proceeds to step 2 when the collation results match. Only. The other electric lock modules 10b and 10c continue to monitor step 1.
In step 2, the electric lock control module 10a having the matching check result confirms the state of the reserved line 18 by the reserved line monitoring means 15. That is, it is confirmed whether a predetermined voltage is applied to the reserved line 18b or 18c of another electric lock control module. At this time, if there is the reservation line 18 to which the predetermined voltage is applied, it is determined that the other electric lock control module 10b or 10c is in the control reservation state, and the process waits for 100 ms in Step 8 and then Step 2
Return to. This timing is performed using the timer 13.

On the other hand, if the predetermined voltage is not applied to the other reserved line 18, the other electric lock control module 10b.
Alternatively, it is determined that 10c is not in the reservation control state, and the process proceeds to step 3. In step 3, the reserved line monitoring means 15 outputs a predetermined voltage to its own reserved line 18a.

In step 4, waiting for the passage of time according to the priority of the user set in the priority setting means 14,
Go to step 5. Here, the time according to the priority is a time according to the priority of each electric lock module 10 preset in the priority setting means 14, and a shorter time is set in the timer 13 as the priority is higher. It In step 5, the states of the other reservation lines 18b and 18c are confirmed in the same manner as in step 3 described above, and if the other electric lock control modules 10b and 10c are in the control reservation state, the process proceeds to step 9. On the other hand, the other electric lock control modules 10b, 1
If 0c is not in the control reserved state, the process proceeds to step 6.

In step 6, a control signal is sent from the electric lock control signal output means 17 to the electric lock 2a via the signal line 43a to operate the electric lock 2a for locking and unlocking. Step 7
Then, the application of the predetermined voltage to the own reserved line 18a is stopped, and the process returns to step 1. In step 9, the priority of the other electric lock control module 10b or 10c in the control reserved state is compared with its own priority, and when its own priority is the highest, the process proceeds to step 6 to perform the above-mentioned operation. On the other hand, if there is an electric lock control module 10b or 10c having a higher priority than its own priority, the process proceeds to step 10.

In step 10, the own reservation line 18
After stopping the output of the predetermined voltage to a, and waiting for about 100 ms using the timer 13 in step 11,
Return to step 2. In addition, after confirming the control reservation state in step 2 above, further confirming the control reservation states of the other electric lock control modules in step 5 is performed by the plurality of electric lock control modules 10 simultaneously operating the plurality of electric locks. This is because even if a plurality of control signals are received at the same time, such as when receiving a locking / unlocking control signal for controlling the plurality of electric locks, the plurality of electric locks are not driven at the same time. In this case, step 2
At this stage, no electric lock control module 10 outputs a predetermined voltage to the reservation line 18. On the other hand, at the stage of step 5, each electric lock control module 10 outputs the control reservation. Therefore, in step 5, the control reservation states are confirmed again in descending order of priority.

Then, since the waiting time corresponding to the priority order is waited in the above-mentioned step 4, in step 9, the own electric lock control module should have the highest priority order, normally. Step 9 to Step 6
It will go to. However, due to electromagnetic noise etc.,
When the electric lock control module having a low priority proceeds to step 5 before the electric lock module having a high priority, the process proceeds from step 9 to step 10 in the electric lock control module having a low priority.

As is clear from the above description, even if lock / unlock control signals are simultaneously input to a plurality of electric locks 2,
Multiple electric locks will not operate at the same time. Therefore, the power supply for the electric lock is sufficient if it has a capacity for operating only one electric lock, and a small-capacity and small-sized power supply device can be used. Further, even when the power source is incorporated in the electric lock control device, the electric lock control device can be downsized.

Although the electric lock control module is provided for each electric lock in the example described above, a plurality of electric lock control modules are realized by one software to control each electric lock. It can also be monitored. Further, in the above example, the locking / unlocking control signal is transmitted from the card reader or the ten-key pad connected by the signal line to the electric lock control device, but the locking / unlocking control is performed by the external button provided in the electric lock control device. The signal may be obtained, or the locking / unlocking control signal may be obtained from a security system connected to the electric lock control system.
