Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security system installed in a facility to be managed, such as a building, and in particular, not only manages entering and leaving humans and monitors the condition of the facility, but also displays and prints required data. The present invention relates to a supervisory control device having a means for performing.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional supervisory control device of this type is constructed by connecting a terminal device 10, a relay device 20, and a man-machine device 30 via a transmission line such as a bus.
The terminal device 10 includes a card reader 11 for reading the card information inserted at the time of entering / leaving the facility to be managed, a sensor 12 for constantly monitoring the state in the facility to issue an alarm and restore it, and a card reader 11 of the card reader 11. The management target information generation unit 13 is configured to generate the information indicating the entry / exit status based on the output, and generate the sensor state information information based on the detection information of the sensor 12 issued and restored. Generated entry / exit information and sensor status information (hereinafter, management target information)
Is sent to the relay device 20 via the transmission path.

The relay device 20 performs predetermined facility management based on the input / output interface 21 connected to the terminal device 10 and the man-machine device 30 so that they can communicate with each other and the management target information sent from the terminal device 10. The management unit 22 notifies the man-machine device 30 of this management target information. The management unit 22 includes a man-machine device 30.
When a remote control instruction for each unit of the terminal device 10 is received from the terminal device 10, it also has a function of notifying the terminal device 10 of that fact.

The man-machine device 30 presents the management target information to the operator visually or acoustically and accepts the input of necessary instruction data. The man-machine device 30 is connected to the relay device 20 so as to be capable of mutual communication. An output interface 31, a database 32 that stores the management target information transferred from the relay device 20, a display unit 33 that displays the information stored in the database 32, and a printing unit 34 that prints if necessary. An output control unit 35 that controls output to the display unit 33 and the printing unit 34, a data input unit 36 that receives a remote control instruction or the like for the terminal device 10, and the received instruction information via the input / output interface 31 to the relay device 20. And a control instruction section 37 for notifying the user.

In the supervisory control device having such a configuration,
When the card is inserted into the card reader 11 or the sensor 12 is issued or restored, the terminal device 10 generates management target information and sends it to the relay device 20. The relay device 20 is
This management target information is transferred to the man-machine device 30. The man-machine device 30 sequentially accumulates the transferred information in the database 32, displays required instruction information on the screen of a display device or the like, prompts the operator to perform an operation instruction, and performs a printing process or the like.

[0006]

By the way, the frequency of entry / exit to / from the facility and the alarm / restoration of the sensor 12 greatly differ depending on the scale of the facility to be managed and the number of users. Also,
The frequency of these occurrences usually varies depending on the time of day. That is, the load of the monitoring control device changes frequently.
However, the conventional monitoring control device does not perform processing for restricting or relaxing the screen display and printing of the instruction information according to the fluctuation of the load. Therefore, for example, when there is a large number of entrances and exits to the facility and a large number of reports and restorations of the sensor 12, if there is an instruction to display or print the required information based on the accumulated information in the database 32, the security system is supposed to In some cases, the functions of entry / exit management and status monitoring that were required in the past were hindered. Particularly, since a considerable processing time is required for the printing process, there has been a problem that the response speed of the process associated with the entry / exit management and the like is lowered. Further, there is a case where processing processing of accumulated information is required for displaying or printing, but conventionally, this processing processing has only been performed during a time period when the load on the monitoring control device is small.

In view of the above problems, an object of the present invention is to provide a technique capable of ensuring the original function of the security system by reducing the load of the monitor and control device, which involves displaying, printing, or processing accumulated information. Especially.

[0008]

In order to solve the above problems, the present invention has a management object information generating means for detecting the entry / exit situation and sensor status of a management object facility and generating management object information. A monitoring control apparatus comprising: a data management unit that performs predetermined security management including condition monitoring of the facility based on management target information; and a man-machine device that includes a first database that stores the management target information. , At least the first database is connected to a communication path, and communication setting means for selectively setting or canceling communication to the first database based on a command, and storing in the first database at the time of communication setting A second database for copying the copied management target information, an information processing means for processing the copied management target information, and the information processing hand In the processed machining apparatus provided with a data output control means for outputting control information, characterized in that detachably provided on the communication path.

Further, preferably, there is further provided a control means for generating a communication setting command upon attachment to the communication path and generating a communication setting cancellation command upon departure from the communication path. And either of the communication setting cancellation commands is sent to the communication setting means.

[0010]

[Operation] When a person enters / exits a sensor, or a sensor is issued or restored in the facility to be managed, the managed information indicating the entry / exit status and the sensor state is generated at any time, and this is the first database arranged in the man-machine device. Accumulated in. This accumulated information is displayed on the screen of the display unit in the man-machine device, and necessary instructions are presented to the operator. Here, when the processing device is connected to the communication path, the communication setting means sets the communication path with the man-machine device based on the command, and the accumulated information of the first database is stored in the second database. Make a copy.
It is also possible to remove the processing device during normal operation and connect the processing device to the communication path as needed. In this case, the control means generates a communication setting command when connecting to the communication path. And send it to the communication setting means,
Information can be automatically fetched from the first database to the second database, and the communication setting cancellation can be sent upon the departure from the communication path to enable the automatic fetch cancellation.
Then, the display of information other than the operation instruction, the printing process, and the processing process are performed based on the information in the second database. Since the processing device does not need to consider the load of the security system, it is possible to freely perform information retrieval processing and change the layout of screen display and printing at any time.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention, in which components having the same functions as those of the conventional monitoring and controlling apparatus shown in FIG.

The supervisory control device of this embodiment is a terminal device 1.
0, the relay device 20, and the man-machine device 30 as a basic configuration, and further includes a data processing device 1 detachably connected to a communication path such as a network. As the basic component, the same one as the conventional monitor and control device shown in FIG. 2 can be used.

The data processing device 1 is a man-machine device 30.
I / O interface 2 for performing mutual communication with the I / O interface 31 of
Connected to the database 3, a processing unit 4 for processing the information stored in the database 3, and an output control unit 5 for outputting the processed information to the display unit 6 or the printing unit 7.
And a main controller 8 that controls the communication timing of the input / output interface 2 and the timing of processing. The data processing device 1 operates at a timing independent of the basic configuration of the terminal device 10, the relay device 20, and the man-machine device 30.

The data processing apparatus 1 can be realized by a programmed general-purpose personal computer or workstation, and a general-purpose network can be used as a communication path.

In the supervisory control device having the above configuration, when the management target information is sent from the terminal device 10 to the relay device 20,
The relay device 20 performs entry / exit management and sensor state monitoring, and transfers management target information to the man-machine device 30. The man-machine device 30 stores the management target information received via the input / output interface 31 in the database 32.
Accumulate in. Further, the stored information is taken out from the database 32 as needed, and the necessary instruction information is displayed on the display unit 33.

Here, when printing a large amount, a data transfer instruction is input from the data input section 36. The control instruction unit 37 sends this instruction to the input / output interface 31 and sends the accumulated information in the database 32 to the data processing device 1. On the data processing device 1 side, this accumulated information is stored in the database 3. Further, according to a print instruction from the data input unit 36, the output control unit 5 takes out necessary information from the database 3 and prints it on the print unit 7. It should be noted that it is also possible to perform only the transfer between the databases 32 and 3 at any time and to perform printing afterwards. In this way, when access to the facility or notification / recovery of the sensor occurs frequently, processing associated with access control or status monitoring can be preferentially executed.

In the case of retrieving required information or changing the layout of display or printing, the corresponding instruction is input from the data input section 36 of the man-machine device 30 and the control instruction section 37 and It is sent to the data processing device 1 via the input / output interface 31. In the data processing device 1, the processing unit 4 is caused to perform the corresponding process under the control of the main control unit 8. This processing can be performed at an arbitrary time independently of the processing associated with facility management, and it is possible to prevent the influence on the entry / exit management or the processing associated therewith. After the processing, the changed data may be stored again in the database 3 and may be set in the main controller 8 so as to be transferred to the database 32 of the man-machine device 30.

Although the above description is based on the premise that the data processing device 1 is connected to the man-machine device 30 in advance, it is normally operated only by the terminal device 10, the relay device 20, and the man-machine device 30. However, only when data processing is required, the data processing device 1 may be attached to the communication path and the necessary information may be loaded into the database 3. In addition, at that time, the main control unit 8 sends a communication setting command to the input / output interface to establish the communication path upon attachment to the communication path, and on the other hand, to release the communication setting command upon disconnection from the communication path. If the procedure for sending the data and canceling the setting is set in the main control unit 8, the communication path is automatically set or released when the data processing device 1 is attached or detached. Sexuality is greatly improved.

Further, as is apparent from the above description, the monitoring control apparatus of the present embodiment is not focused on dividing the conventional functions, but on the point of distributing the processing that causes an excessive load. For example, when performing security management for a small building or the like having a light load constantly, only the terminal device 10, the relay device 20, and the man-machine device 30 may be operated as in the conventional case. As a result, it becomes possible to flexibly perform only the operation while generalizing the device configuration.

[0020]

As described above, according to the supervisory control device of the present invention, the access control function and the status monitoring function, which are important for the security system, have an excessive load such as print processing and information processing processing. It is not hindered by the processing, and has the effect of improving the reliability in system operation.
