Description

  The present invention is a security that centrally monitors and controls a plurality of security monitoring terminal devices that monitor and report fires and crime prevention situations provided in a wide area from a base side device installed at a monitoring base. More particularly, the present invention relates to a security monitoring control system capable of monitoring and controlling one security monitoring terminal device from two or more monitoring bases.

  In recent years, with the rapid advancement of electronic technology and IT-related technologies, multiple security monitoring terminal devices (hereinafter simply referred to as “monitoring terminals”) that monitor fires and crime prevention situations, such as subscriber line networks and ISDN Security monitoring and control systems that centrally monitor and control from base-side devices (hereinafter simply referred to as “base-side devices”) installed at a monitoring base via a network have come to be widely used.

  In such a security monitoring and control system, the reliability of the system is strongly demanded for the purpose of security monitoring of fire and crime prevention situations. For this reason, for the base side equipment, for example, the active system and the standby system are duplicated, and if any failure occurs in the active system, the system is switched to the standby system to ensure the sustainability of the operation as a security monitoring control system. Measures to take are taken.

  Furthermore, from the recent remarkable development of various communication networks, a significant reduction in communication costs, or an increase in concerns about wide-area disasters such as large-scale earthquakes, for example, in remote locations as shown in Patent Document 1 and Patent Document 2 A duplex system capable of monitoring and controlling each monitoring terminal from two or more monitoring bases provided has also been proposed.

  Such duplication further ensures the redundancy of the entire system. Even if a monitoring base in one region loses its function due to an accident or disaster, the monitoring base in another region can quickly Backup processing is possible. Thereby, even when an accident or disaster occurs, the security monitoring operation is not interrupted, and the reliability of the security monitoring control system itself can be further improved.

  However, these conventional techniques take the form of switching the monitoring / control of a plurality of monitoring terminals from the base-side device of the active system to the base-side device of the standby system when a failure occurs. For this reason, with such switching, the base side equipment that will newly bear the monitoring work will increase the number of newly monitored terminals in addition to the conventional monitoring terminals, so the load temporarily increases As a result, the normal monitoring / control processing may be hindered.

Limited to some areas.

  Furthermore, in the prior art disclosed in Patent Document 2, although synchronization between the base-side devices is taken into account by a dedicated network connecting the base-side devices, data transmitted between the base-side devices is mainly The data is limited to data indicating the communication state between the site side device and the monitoring terminal. For this reason, a base-side device that has newly inherited monitoring / control of a monitoring terminal needs to grasp the status of the monitoring terminal by transmitting and receiving data to and from the monitoring terminal anew. The problem of the accompanying temporary increase in load remained.

  For this reason, when the business at one base-side device becomes busy, the base-side device provided at the other base can perform security monitoring / monitoring on the monitoring terminal under the jurisdiction of the base-side device at which the business is busy. It is also possible to perform part of the control work.

  That is, in the system of the present invention, for each monitoring terminal installed at the contracting party, the monitoring console provided in the site-side device to which the transmission data from the terminal is allocated is stored in the database in the site-side device. It is specified by the setting table.

  Therefore, changing the processing assignment of the transmission data from the monitoring terminal of the contract partner to be substituted to another place (non-busy place) in response to busy conditions, etc., the database setting table from the concerned base side This can be done by changing the designation. Further, such designation can be performed across both bases AB. Therefore, if the setting table is created in advance so as to straddle both bases AB, it is not necessary to change the setting during busy periods.

  When the base side device receives the transmission data from a predetermined monitoring terminal, a “notification dialog”, which will be described later, is created on all of the monitoring consoles specified in advance, and the monitoring operation is performed together with the sounding of the alarm. Displayed on the desk display screen. Then, in any of the monitoring consoles where the alarm is first reset by the operator who has recognized the notification, a “command card” to be described later is displayed, and thereafter, the monitoring console performs processing for the monitoring terminal. Will be responsible. Thereby, in the system of the present invention, the redundancy of the entire security monitoring control system can be increased.

It becomes possible to quickly take over the security monitoring / control work for the security monitoring terminal, and the reliability of the security monitoring control system as a whole can be improved.

  A plurality of embodiments, which are the best mode for carrying out the present invention, will be described below with reference to the accompanying drawings.

  First, the configuration of a security monitoring control system (hereinafter simply referred to as “the present system”) according to one embodiment of the present invention is shown in the block diagram of FIG. In the figure, a monitoring terminal 20 is a security monitoring terminal device installed in an office, factory, or general home. Therefore, the monitoring terminal 20 is connected with, for example, a disaster prevention sensor that monitors fire and smoke generation, and various security sensors that detect intrusion detection and opening / closing of windows and doors. When a change in the status of the monitoring target is detected by these sensors, the monitoring terminal 20 is configured to transmit an alarm signal to the base-side device 10 described later.

  Furthermore, photographing devices such as security cameras are connected to the monitoring terminal 20, and image signals from these devices are also transmitted to the base-side device 10 as necessary. The monitoring terminal 20 executes control processing such as camera zoom adjustment and camera angle adjustment, for example, in accordance with various control signals received from the site-side device 10.

  Further, the monitoring terminal 20 can transmit the monitoring status by various sensors at that time and the monitoring image by the security camera to the site side device 10 in response to the request signal from the site side device 10, or These monitoring statuses and the like can be transmitted to the base-side apparatus 10 at predetermined time intervals.

  The communication network 30 is a communication network that connects the monitoring terminal 20 and the site side device 10, and may be, for example, a normal subscriber telephone network, or a digital line network such as ISDN, a digital packet network, or the like. Other various network lines for data communication may be used.

  The site-side device 10 is a monitoring control device installed at a monitoring base such as a security center or a central monitoring center operated by a security company, for example, and the monitoring terminals 20 in a monitoring area managed by the monitoring base are collectively displayed. It is a device that monitors and controls.

  As shown in FIG. 1, the site-side device 10 mainly includes a control server 11, a terminal interface unit 12 (hereinafter simply referred to as “terminal I / F unit 12”), and an inter-site interface unit 13 (hereinafter simply referred to as “ A base I / F unit 13 ”), a database 14, and a monitoring console 15. Needless to say, these parts are connected to each other by a bus line in the base-side device 10 or a LAN provided in the base A.

  The control server 11 is a part that controls the above-described parts constituting the base-side device 10 through such a bus line or LAN, and forms, for example, a microprocessor, a memory circuit, and its peripheral circuits. It consists of various circuits. In addition, although the single control server 11 is shown in the block diagram of FIG. 1, from the viewpoint of ensuring the reliability of the entire base-side device 10, for example, the configuration of the control server 11 is a master that operates in the active system. It is preferable to configure as a duplex system separated into a server and a slave server operating as a backup system for backing it up.

  The terminal I / F unit 12 is a part responsible for transmission / reception of various data with the monitoring terminal 20 via the communication network 30. Incidentally, the data received from the monitoring terminal 20 includes, for example, an abnormality occurrence notification from various sensors connected to the monitoring terminal 20, an image signal from the monitoring camera, and the like. On the other hand, the data transmitted to the monitoring terminal 20 includes, for example, an adjustment signal for the monitoring camera, a control signal for various machine security devices connected to the monitoring terminal 20, a reset signal, and the like.

  In FIG. 1, only one terminal I / F unit 12 is drawn inside the base-side apparatus 10, but in this system, depending on the operation status, the type of the communication network 30 actually used, and the like. Needless to say, a plurality of terminal I / F units 12 of various types and specifications corresponding to each communication network are provided.

  For example, when a normal analog subscriber line network is used as the communication network 30, the terminal I / F unit 12 including an NCU (network control circuit) is used, and when an ISDN line is used, a DSU (digital A terminal I / F unit 12 dedicated to an ISDN line having a service unit) is used. Further, when an IP network is used as the communication network 30, a VPN (virtual private network) interface device or the like is used as the terminal I / F unit 12.

  The base I / F unit 13 is a part responsible for transmitting and receiving data to and from the base-side device 10 installed at another base via a high-speed transmission path 40 described later. The terminal I / F unit 12 described above. Similarly to the above, various equipments are provided according to the type and specification of the high-speed transmission path 40 used.

  The database 14 is, for example, a data storage unit configured from a storage medium such as a hard disk memory or a semiconductor memory, and various types of data related to all the monitoring terminals 20 in the monitoring area under the jurisdiction and various operations in the site side device 10. This is the part where data is stored.

  The monitoring console 15 is a console portion for an operator resident at the monitoring base to monitor and control each monitoring terminal 20. Therefore, on the display screen provided in the monitoring console 15, monitoring statuses by various sensors connected to each monitoring terminal 20, captured images from the monitoring cameras, and the like are displayed as necessary.

  In addition, from the operation panel of the monitoring console 15, the operator inputs control data for each monitoring terminal 20, various setting data, and the like. Incidentally, the monitoring console 15 may be configured to use an off-the-shelf personal computer, or a dedicated console provided with a display screen and an operation panel specialized for security monitoring work may be used. .

  The base-side device 10 described above is provided in both the base A and the base B shown in FIG. 1, and each device has the same component. However, the number and type of terminal I / F units 12 included in each base-side device, or the number of monitoring consoles 15 are determined according to the security monitoring work implementation and implementation scale at each base, respectively. It goes without saying that they are different.

  The high-speed transmission path 40 may be configured to use a dedicated line such as a high-speed digital line, or may be configured to use an IP network capable of data transmission at a high speed such as a wide area Ethernet (registered trademark). There may be. In the data transmission between the bases, the contents of the data table included in the database 14 of each base-side device 10 may be transmitted to each other. Therefore, the high-speed transmission path 40 can transfer a relatively large amount of data. A communication path capable of transmitting at a speed is preferable.

Next, processing operations in the present system will be described with reference to the accompanying drawings. In the following description, the flow of processing in this system is
(1) Processing when receiving monitoring data from the monitoring terminal (2) Various setting data input processing to the contracted party (3) Control data input processing to the monitoring terminal (4) Four processing of synchronization repair processing between bases The explanation is roughly divided into the following.

(1) Processing at the time of receiving monitoring data from the monitoring terminal First, based on FIG. 2, processing in the base side apparatus 10 when receiving monitoring data from the monitoring terminal 20 will be described.

  In the monitoring terminal 20 in the monitoring area A under the jurisdiction of the base A, when any change occurs in the detection signal of the sensor connected to the terminal, the monitoring terminal 20 transmits the change to the base-side apparatus 10 via the communication network 30. The change data representing the change in the state of the security site is reported. In the description of the present embodiment, there are n contract destinations of a user who has contracted with a security company having jurisdiction over the mechanical security in the monitoring area A, and there are n monitoring terminals associated therewith. Assume that

  In the base-side device 10, when the terminal I / F unit 12 receives a transmission signal from the monitoring terminal 20 that has notified the change data, the base-side device 10 notifies the control server 11 of this. As a result, the reception processing task 11a in the control server 11 is activated, and the reception processing task 11a creates signal information data based on the change data. Incidentally, the signal information data refers to data in a predetermined integrated format in which change data transmitted from various monitoring terminals 20 existing in the monitoring area A are aggregated.

  Note that each processing task appearing in the following description, including the reception processing task 11a, represents one processing unit of software processing executed by the microprocessor included in the control server 11, and the control server 11 Needless to say, they do not exist as independent hardware components.

  The signal information data created by the reception processing task 11a is notified to the journal processing task 11b and the notification processing task 11c in the control server 11. The journal processing task 11b is a processing task for creating journal data recorded and displayed as a journal from the signal information data.

  Incidentally, the journal is a recording of signal information received from a monitoring terminal installed in each contracted user in time series, and corresponds to a daily report, a monthly report, etc. in a so-called data log system. In other words, the journal data in this case is generated by the operator of the monitoring console 15 at the monitoring terminal 20 by adding the name of the contractor or a predetermined color code for display on the display screen to the signal information data. Data in a form that can easily determine the contents of the status change.

  The journal data is supplied to the monitoring console 15, displayed as a list on the display screen of the monitoring console 15, and sent to a journal database 14 a (hereinafter referred to as “journal DB 14 a”) provided in the memory area of the database 14. . The journal DB 14a is a database that stores journal data, and has a data table that stores journal data for each contract destination in time series. Therefore, the journal data sent from the control server 11 is stored in a predetermined data table corresponding to the contract destination.

  In the configuration of the data table of the journal DB 14a, one record corresponding to one row of the table corresponds to one journal, and various information such as the reception date / time and received contents of the journal is stored in one record. The The configuration of the data table included in the journal synchronization error DB 14b described later is the same as that of the data table of the journal DB 14a.

  On the other hand, the notification processing task 11c creates notification data based on the signal information data received from the reception processing task 11a. Here, the notification data is data in which various information such as a contract name and a notification sound code for the operator of the monitoring console 15 are added to the signal information data. Data in a form that can easily convey the state change report.

  Such notification data is supplied to the monitoring console 15 and displayed on the “notification dialog” and “command card” on the display screen of the monitoring console 15. Incidentally, the alert dialog is a dialog box displayed on the display screen of the monitoring console 15 together with a predetermined warning sound when the state change data from the monitoring terminal 20 is received. Further, the command card is a partial display screen generated for each monitoring terminal of the contracted user, and the contents of the alarm at the time of the alarm and the security state are displayed in a compact manner, and the current status of the monitoring terminal 20 of the contracted user is displayed. It has a configuration that can be grasped at a glance.

  In parallel with the above processing, the control server 11 transmits the signal information data generated by the reception processing task 11a from the base I / F unit 13 to the base B via the high-speed transmission path 40. Transmit to device 10. In response to this, in the site side apparatus 10 at the site B, the journal processing task 11b and the notification processing task 11c of the control server 11 are activated, and the same processing as in the case of the site A described above is executed.

  That is, also at the base B, journal data and report data are created based on the signal information data received from the base A and supplied to the monitoring console 15. At the same time, the journal data is also supplied to the database 14 at the site B and stored in a data table for each contract destination provided in the journal DB 14a. In this way, in the base side apparatuses 10 at both the A and B bases, the same information is shared regarding the security status of one monitoring terminal, and the synchronization of the monitoring information is maintained at both bases. It shall be defined as a state.

  By the way, the monitoring terminal 20 in the monitoring area A is not the original jurisdiction for the base B, and when the monitoring function of the base A is operating normally, the monitoring terminal 20 intentionally performs monitoring from the base-side device 10 of the base B. There is no need. Therefore, in this system, when both bases are functioning normally, at the base B, the monitoring console 15 does not display journal data or report data generated based on the signal information data received from the base A. Such an operation mode can be selected.

  Such an operation mode can be freely set by an operation procedure designation table (not shown) provided in the database 14. Furthermore, for example, by setting the table, data received from a predetermined monitoring terminal 20 can be distributed to a specific monitoring console 15 for display / reporting.

  On the other hand, when transmitting signal information data from the base A to the base B, the base I / F units 13 of both bases are configured to transmit data while confirming transmission / reception with each other. Therefore, for example, when data from the base A cannot be transmitted to the base B due to a line failure in the high-speed transmission path 40, the control server 11 at the base A can recognize the situation.

  In such a case, the control server 11 records matters relating to the signal information data not transmitted to the base B in the journal synchronization error database 14b in the database 14 (hereinafter referred to as “journal synchronization error DB 14b”). The configuration of the journal synchronization error DB 14b is the same as that of the journal DB 14a described above, and includes a data table for each contract partner.

  Therefore, matters relating to the signal information data not transmitted to the base B are stored in a predetermined data table corresponding to the contract destination in the journal synchronization error DB 14b. It should be noted that the signal information data that has not been transmitted can be repaired, that is, transmitted to the site B by the method described in (4-1) Manual synchronization repair processing or (4-2) Automatic synchronization repair processing described later. Will be done.

  In the above description, the processing of the base-side device 10 at the base A when the change data is received from the monitoring terminal 20 in the monitoring area A has been described. However, the change data from the monitoring terminal 20 in the monitoring area B has been described. It goes without saying that the same processing is performed at the site B even when the message is received.

  As described above, according to the present system, the change data from the monitoring terminal 20 received at one of the two bases A and B is transferred to the other base in real time and transferred to the respective databases 14. At the same time, the data is issued and displayed on the display screens of the monitoring consoles 15 at both sites.

  Therefore, even if a failure occurs in the base-side device 10 of one base by ensuring synchronization between the two bases regarding the received data from the monitoring terminal 20, the base of the other base The side device 10 can immediately continue the monitoring operation for the monitoring terminal, instead of the site-side device 10 at the failure occurrence site. Moreover, since the state can be monitored from the base-side devices 10 at both bases for one terminal, the redundancy of the entire system can be increased.

(2) Inputting process of various setting data to contractor Next, an input process of various setting data to each contractor in the site side apparatus 10 will be described with reference to the explanatory diagrams shown in FIGS. Incidentally, the various setting data are various data relating to each contractor provided with the monitoring terminal. For example, the name and contact information of the contractor, or the attribute of the monitoring terminal installed in the contractor Data that represents information necessary for security.

  As shown in FIG. 3, these data are stored on each table (TBL1-N) included in the setting database 14c (hereinafter referred to as “setting DB 14c”) in the database 14. For example, the basic information table (TBL1) of the setting DB 14c stores basic information such as the name of the contractor and the location of the head office, and the contact information table (TBL2) contains information about these contractors. Information such as the telephone number and mail address is stored.

  FIG. 4A shows an outline of the configuration of each table included in the setting DB 14c. In the figure, one line is a storage area called a record and having a data length of about 10 to 200 bytes. The number of records in which information about one contractor is stored is set within a range of about 10 to 500 records depending on the amount of information related to the contractor. Accordingly, in one table, the number of records corresponding to the information amount of each contractor is accumulated in the order of contractor 1 to contractor n.

  The setting DB 14c is provided with N tables TBL1 to N for different fields such as basic information and contact information. However, since the amount of information of each contractor differs for each field, The size of each table of TBL1-N is different.

  Next, specific operations of various setting data input processing will be described. In the base-side device 10, when the operator performs various setting data input processing, first, the customer information management task 11 d of the control server 11 is activated from the monitoring console 15. As a result, information about the contractor that the operator intends to input (change) the setting data is extracted from various tables included in the setting DB 14c, and so-called customer information in which various types of information regarding the contractor are aggregated. It is formed.

  For example, when the operator intends to input (change) the setting data related to the contractor 2, the customer information management task 11d stores various data such as basic information and contact information regarding the contractor 2 in each table in the setting DB 14c. (TBL1 to N) are picked up in record units, a customer information file in which these are collected is created and displayed on the display screen of the monitoring console 15.

  In parallel with the above processing, the control server 11 accesses the editing exclusion table 11f and checks the state of the flag corresponding to the contract partner 2 in the table. Here, the edit exclusive table 11f is a data table provided in the memory area of the control server 11, and as shown in FIG. 4B, a table having a 1-bit flag for each of the contracting partners 1 to n. It is. Note that the editing exclusive table 11f may be provided in the database 14 in the same manner as other data tables.

  The flag corresponding to each contract partner in the edit exclusion table 11f is set when the setting data is being input from any of the monitoring consoles 15 with respect to the contract partner (the flag bit is “1”). Otherwise, it is reset (the flag bit becomes “0”). That is, when the flag corresponding to the contracted party 2 in the editing exclusive table 11f is 1, since the setting data input process for the contracted party 2 has already been performed from another monitoring console 15, it is started by the current operator. The input processing of the set data is rejected.

  On the other hand, when the flag corresponding to the contracted party 2 in the edit exclusive table 11f is 0, the setting data for the contracted party 2 is not input from the other monitoring console 15 of the base A, so the control server 11 Then, the editing exclusive table 11f in the base side apparatus 10 provided in the base B is accessed via the base I / F unit 13 and the high-speed transmission path 40, and the state of the flag corresponding to the contracted party 2 in the base table is checked. To do.

  As a result, when the flag corresponding to the contract destination 2 is determined to be 1 in the editing exclusion table 11f on the site B side, the setting data input processing for the contract destination has already been performed from any monitoring console 15 at the site B. Therefore, the setting data input process started by the current operator is rejected in the same manner as described above.

  On the other hand, if the flag is 0, the base B side has not performed the setting data input process for the contracted party 2, and therefore the control server 11 on the base A side performs entry processing on the edit exclusion table 11f. The contractor 2 flag is set (from 0 to 1). The result of such an entry is notified to the operator via the monitoring console 15, and the operator who has recognized this is intended for the contract partner 2 based on the customer information file displayed on the display screen of the monitoring console 15. A setting data input (change) process is executed for the field information.

  In each table in the setting DB 14c, only the records related to the data changed by the setting data input process are rewritten. When the input (change) of the setting data for each table in the setting DB 14c is completed, the control server 11 accesses the editing exclusive table 11f again and resets the contracted party 2 flag (from 1 to 0).

  In parallel with the above processing, the control server 11 accesses the site B again via the site I / F unit 13 and the high-speed transmission path 40, and records the input (change) items of the setting data performed on the site A side. The data is transmitted to the site side apparatus 10 on the site B side in units. In response, in the site-side device 10 on the site B side, the control server 11 activates the file management task 11e.

  The file management task 11e is a task responsible for maintaining synchronization between the two sites for the recording data of each table of the setting DB 14c. Therefore, the file management task 11e performs a writing process on each table included in the setting DB 14c on the site B side in accordance with the change items of the various setting data transmitted from the site A. It goes without saying that the processing for writing into the table is also performed in units of changed records as in the case of the site A.

  The control server 11 at the site A is included in the synchronization management database 14d (hereinafter referred to as “synchronization management DB 14d”) in the database 14 at the site A after completing the transmission (setting) of setting data to the site B side. Access the synchronization management table.

  As shown in FIG. 4C, the synchronization management table has a configuration in which one flag bit is assigned to one record of each table (TBL1 to TBLN) included in the setting DB 14c. . Incidentally, such a flag bit represents a synchronization holding status for a record corresponding to the flag.

  The control server 11 accesses the synchronization management table, resets the flag for the record that has been successfully transmitted to the base B among the changed setting data, and sets the flag for the record that has caused a problem in transmission. To do.

  That is, when the flag of the synchronization management table is “0”, synchronization is maintained for each record in the table corresponding to the flag, that is, the same setting data is stored in the tables on the setting DBs of both AB sites. It is recorded. On the other hand, when the flag is “1”, the synchronization of the record is lost, that is, the setting data update at the site A (B) is not reflected on the site B (A) side. become.

  In the above description, the case where the setting data input process is performed at the site A has been described as an example, but it goes without saying that the same applies to the case where the setting data input process is performed at the site B. In this case, the setting data transmitted from the site B side is written to each table (TBL1 to TBLN) in the setting DB 14c by the file management task 11e on the site A side.

  As described above, according to the present system, even when the setting data input (change) processing related to the contracted party (monitoring terminal) is performed at either of the A and B bases, the input is performed. The (changed) data is written into the tables in the database 14 at both bases almost simultaneously, and the synchronization of the setting data between the two bases is ensured. Further, when setting data is written to each table in the setting DB 14c, only the changed part is performed in units of records, so that the performance at the time of writing can be improved.

  Furthermore, since the same processing is performed for transmission of setting data to the partner site, data transmission can be performed in a very short time. Thereby, in order to transmit the updated setting data, it is not necessary to occupy the transmission path for a long time, for example, by nighttime batch processing, and the performance when the transmission path is used can be improved.

(3) Control Data Input Processing for Monitoring Terminal Next, control data input processing for the monitoring terminal 20 from the base side device 10 will be described based on FIG. 5 and FIG.

  First, when the operator performs control on a specific monitoring terminal 20, designation of the target monitoring terminal 20 and a control command indicating the content of control are input from the monitoring console 15. Here, the control with respect to the monitoring terminal 20 means, for example, processing such as a command for starting / ending security at the monitoring terminal or a command regarding ON / OFF of various control units incorporated in the monitoring terminal. .

  As a result, the control task 11g in the control server 11 is activated, and various control data input from the monitoring console 15 is stored in a control management database 14e (hereinafter referred to as "control management DB 14e") provided in the database 14. Written in the control management table. The configuration of the control management table is as shown in FIG. 6, and control data for one control process is written for each record.

  For example, in one record of the control management table, the base code indicating the base where the control data is input, the control code indicating the control content, the monitoring terminal number of the control destination, the time when the control data is input, etc. Various data is written. Further, as the accompanying data, for example, the subsequent progress status of the input control process may be written afterwards.

  When the control data is written in the control management table, the control server 11 sends the contents of the control data written this time to the inter-site I / F unit 13 and the high-speed transmission path 40 as in the case of the setting data input described above. To the base-side device 10 of the base B. Also in such transmission processing, since only the changed part of the control management table is transmitted in units of records, the contents of the control data can be transmitted to the site B in an extremely short time.

  On the other hand, the database 14 of the site side apparatus 10 at the site B is also provided with a control management DB 14e similar to the above, and the control data sent from the site A is stored in the control management DB 14e by the control server 11 at the site B. Written in the control management table.

  When the control server 11 at the site A transmits the control data to the site B side, it subsequently starts the download waiting list management task 11h and the download waiting list display task 11i. The download waiting list management task 11h is a task responsible for processing to download control data written in the control management table to a communication processing task (not shown) at a predetermined timing.

  The communication processing task in which the control data has been downloaded selects the terminal I / F unit 12 corresponding to the predetermined communication network 30 designated by the control data, and the destination monitoring terminal 20 designated by the control data is selected. Control data is transmitted in accordance with a predetermined communication processing procedure.

  That is, the control data written in the control management table is not immediately transmitted from the base side device 10 to the monitoring terminal 20 via the communication network 30. This is because, depending on the attribute of the communication network 30, there is a case where the certainty such as the constant connection using the dedicated line cannot be secured in the connection between the base side device 10 and the monitoring terminal 20.

  For example, when the communication network 30 with the monitoring terminal 20 to be controlled is a normal subscriber telephone line, when a call is made from the base side device 10 for control data transmission, the monitoring terminal 20 side normally Control data cannot be transmitted to the monitoring terminal 20 when a call arrives at a telephone or fax machine.

  Therefore, when the communication network 30 is a subscriber telephone line, the site side device 10 waits for an incoming call by a scheduled report from the monitoring terminal 20, for example, and at the time of the incoming call, the control data is received together with the reception of the scheduled report data. Can be said to be reliable. For this reason, it is necessary to make a timing for downloading the control data written in the control management table to the communication processing task. The download waiting list management task 11h manages such timing.

  The system has the same control management table updated in real time at both AB sites. However, the download wait list management process by the download wait list management task 11h described above is performed. Needless to say, this is only when the base code in the control management table indicates control by the local base.

  On the other hand, the download waiting list display task 11i is a task responsible for displaying the contents of the control management table on the display screen of the monitoring console 15 in a predetermined format. The operator can easily confirm the state of the control status of each monitoring terminal 20 from both AB sites by viewing the display screen.

  As described above, according to the present system, the information being controlled is shared in real time at both the AB sites, but since the download waiting list management process is performed by the download waiting list management task 11h, the same contract is used. There is no possibility that the same monitoring terminal placed first will be controlled simultaneously from both bases. In addition, since the control status of the local site and the remote site can always be grasped at a glance, the redundancy of the entire monitoring system can be increased.

(4) Synchronization Repair Process Between Bases Next, a synchronization repair process between bases will be described with reference to FIG.

  Incidentally, the synchronization repair process between the sites refers to a process for maintaining the identity of data included in various tables in the database 14 at both AB sites. In this system, data is exchanged between the AB sites at the various timings described above, and the identity of the data stored in the various tables in the database 14 at both sites is maintained. Yes.

  However, for example, the data may not be transmitted to another site due to a failure of the high-speed transmission path 40 or the like. The synchronous repair process is a process provided to relieve such a situation and restore the identity of the data in the database 14 between the two sites. In this system, there are two processing modes, ie, a manual synchronization repair process and an automatic synchronization repair process, as patterns of the synchronization repair process. Each mode will be described below.

(4-1) Manual Synchronization Repair Process The manual synchronization repair process refers to a synchronization repair process that is performed manually by an operator stationed at the base A (or B). First, an operator who intends to repair synchronization of various data at both AB sites starts an application file (not shown) of a repair information list from the monitoring console 15.

  As a result, various tables included in the journal synchronization error DB 14b and the synchronization management DB 14d in the database 14 are searched, and the contracted party data that is not synchronized at that time is used as the repair information list, and the monitoring console 15 Are listed on the display screen. The operator performs a synchronous repair process based on the repair information list.

  First, when the operator designates a contract destination for synchronization repair from the monitoring console 15, the control server 11 does not synchronize the contract destination from each table in the setting DB 14c, that is, transmission to the base B is an error. Extract the record data. Whether or not synchronization is established can be easily determined by referring to the flag bit of the synchronization management table included in the synchronization management DB 14d.

  The control server 11 transmits the setting data extracted from each table in the setting DB 14c to the base B in record units. In response to this, at the site B, the file management task 11d of the control server 11 at the site B is activated, and the setting data sent from the site A is written in a predetermined table in the setting DB 14c. Further, a predetermined flag bit of the synchronization management table included in the synchronization management DB 14d is reset.

  Similarly, when the control server 11 at the site A confirms that the data transmission to the site B is normally performed, the control server 11 resets a predetermined flag bit of the synchronization management table included in the synchronization management DB 14d of the site. .

  Regarding the journal data, the control server 11 at the site A refers to the journal synchronization error DB 14b, extracts the corresponding data from the journal DB 14a, and transmits this data to the site B in record units. As a result, the journal management task 11b of the control server 11 at the site B is activated, and the journal data sent from the site A is stored in the journal DB 14a at the site.

On the other hand, when the control server 11 at the site A confirms that the transmission of the journal data to the site B has been performed normally, the corresponding journal data is deleted from a predetermined table of the journal synchronization error DB 14b at the site.
By the processing described above, the synchronous recovery of the data between the AB sites by the operator's manual operation is performed.

(4-2) Automatic synchronization repair process The automatic synchronization repair process is a process in which the synchronization management inspection task 11j in the control server 11 included in the site-side apparatus 10 is always operating, and the above-described synchronization repair by manual operation of the operator In this mode, a series of processes are automatically performed. As a result, synchronization repair processing is automatically performed on data that is not synchronized between the AB sites without requiring any operation by the operator.

  As for details of the automatic synchronization repair process, the start of the process is not performed manually by the operator from the monitoring console 15 but, for example, from a predetermined timer control task (not shown) in the control server 11 in time series. Since this is only different from the manual synchronization repair processing in that it is performed by an interrupt signal or the like that is issued automatically, the description thereof is omitted.

  However, in this system, for data that is not synchronized at both bases, it is not possible to determine whether the data in the database 14 at either base is correct, so automatic synchronization repair processing is not performed. Therefore, in such a case, after the operator determines the data of both bases from the list of repair information displayed on the monitoring console 15, manual synchronization repair processing is performed.

  Since the synchronization management inspection task 11j operates in the background of the normal processing operation in the control server 11, it is set to operate at an extremely slow processing speed in order to reduce the influence on other processing tasks. Yes. Therefore, when urgent recovery of data between both bases is urgent, it is preferable to perform an operator's manual synchronization repair process.

  As described above, according to this system, data that is not synchronized between bases can be easily restored by referring to a list of repair information displayed on the monitoring console 15 by the operator. Can do. Further, data relating to a synchronization error occurring at any of the bases is automatically repaired without synchronization via an operator's manual operation by automatic synchronization repair processing.

  Further, in the synchronous restoration process, data transmission between the two bases or data writing to the data table is performed in units of records only for the data having the synchronous error. Can be increased.

  If any of the sites AB stops its function due to an accident or disaster, the reception processing of monitoring data from the monitoring terminal 20 is normal at the remaining sites (that is, sites where the function is not stopped). It is done like time. In this case, a function of transmitting monitoring data to a plurality of bases provided on the monitoring terminal 20 side (a function of transmitting monitoring data to the next reporting destination when monitoring data cannot be transmitted to the first reporting destination) As a result, the monitoring data is transmitted to the base functioning normally.

  The base-side apparatus 10 that has received the report data from the monitoring terminal 20 accumulates these data in the database in the same way as in normal times, and executes predetermined processing. However, since the function stop at the other base can be recognized by the base apparatus 10 that is functioning normally, in such a case, a process for stopping the transmission of the received data to the faulty base is performed. It will be.

  In addition, regarding the input processing of setting data and control data, an operator at a base that is functioning normally is based on an alarm signal that is issued when the function of the base-side device 10 at another base stops. After the function of the side device 10 is switched to the single site operation mode (operation mode in which setting data and control data are input from a single site), the setting data and control data input processing is performed.

  Even in the case of shifting to the backup processing in the event of a failure at another site, the security monitoring control system according to the present invention stores various data relating to the monitoring terminal 20 in the monitoring area of the failure-occurring site. Since it is always shared, it is possible to suppress an increase in load during the migration of backup processing.

  Next, a security monitoring control system of Example 2 which is another embodiment of the present invention will be described. The security monitoring control system according to the second embodiment has the same basic configuration as the system according to the first embodiment. For this reason, in the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and the description thereof is omitted.

First, the configuration of the security monitoring control system according to the second embodiment is shown in the block diagram of FIG.
In the figure, the base-side device 10, the monitoring terminal 20, the communication network 30, and the high-speed transmission path 40 are the same as those in the first embodiment. A feature of the system according to the second embodiment is that base-side devices 10 provided at three or more bases are connected to a wide area network 50 capable of high-speed data communication via a high-speed transmission path 40. .

  Thereby, for example, the base-side device 10 placed at the base A can exchange data between the bases described in the first embodiment with the base-side devices 10 provided at a plurality of other bases. It becomes possible. That is, the base-side devices 10 placed at the respective bases can share the data on the monitoring terminals 20 in the monitoring areas respectively managed by the plurality of bases in real time.

  In order to smoothly perform the monitoring and control processing in such a system, a sequence control table (not shown) is prepared in the database of the base-side apparatus 10 provided at each base, What is necessary is just to define the process procedure by each base side apparatus 10 previously.

  For example, when the function of the site B is stopped, it is determined that 80% of the number of monitoring terminals managed by the site B is entrusted to the site A, and the remaining 20% is entrusted to the site C. You may make it determine the base which transfers the monitoring control to. By configuring such a multiple monitoring control system with a plurality of bases, it becomes possible to dramatically increase the reliability and redundancy of the entire security monitoring control system.

  The present invention is not limited to each embodiment described above. For example, the shape and arrangement of each part constituting the present invention, or its material, etc., do not depart from the spirit of the present invention. Needless to say, it can be changed as appropriate according to the actual implementation.

The configuration of the present invention described above can be used in, for example, a wide-area monitoring and control system performed by a security company, a local government, or a specific government office.
