Abstract

PURPOSE:To improve the reliability of information supervision control, by calling the centralized supervisory controller of another building control system by auto-dialing when the centralized supercisory controller of its own system becomes faulty and supervising its own building by transmitting generated information. CONSTITUTION:The telephone number of a centralized station A is stored in remote devices RMA1, RMQ2... and information is transmitted to the centralized station A by auto-dialing the telephone number. In addition, the telephone number of another centralized station B is also stored in advance and, when the station A is fauly, the telephone number is automatically switched to that of the station B. Even if the remote device RMA1 auto-dials the telephone number of the station A in order to transmit the information of its own building, the device RMA1 cannot comunicate with the station A when the station A becomes faulty. Then the device RMA1 auto-dials the previously stored telephone number of the station B and transmits the information to the station B. Therefore, information of its own building can be backed up.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application This invention relates to a backup system for a building group management system that monitors and controls information from equipment such as power, air conditioning, and disaster prevention equipment in a plurality of buildings.

B6 Summary of the Invention This invention provides a backup method for a building group management system, in which information from equipment is transmitted through a telephone exchange installed in each building. When a control device malfunctions, the information for that building is transmitted to the pre-designated central monitoring and control device in another building via the telephone exchange, making the central monitoring and control device redundant within the same building. This makes it possible to improve the reliability of information monitoring and control even if there is no need to do so.

0. Conventional technology The building group management system centrally monitors and controls information from equipment such as power, air conditioning, and disaster prevention equipment in multiple small and medium-sized buildings, and integrates the monitoring and control with a central control center device via public telephone lines. It is a system that performs integrated management and control.

D0 Problems to be Solved by the Invention The above-mentioned building group management system has a problem in that if the equipment of the central control center device breaks down, the building group management control function is lost. Therefore, in order to improve the reliability of the central control center equipment, it is possible to duplicate the equipment, but this has the disadvantage that the utilization rate of the equipment that serves as standby equipment is extremely low, and the equipment cost increases. There's a problem.

Means for Solving Problem E6 This invention provides each building with a remote device, a telephone exchange, and a central monitoring control device, and the remote device stores in advance a telephone number for selecting its own and other central monitoring control devices. The remote device also has an auto-dial function, and the remote device transmits the collected occurrence information to its own central monitoring and control device via a converter. In the event of a failure, the phone number of the central monitoring and control device of another building group management system is automatically dialed and the generated information is monitored and controlled by the other central monitoring and control device.

79 Effects This invention, when one's own central monitoring control device malfunctions, automatically dials and calls up the central monitoring control device of another building group management system stored in advance in a remote device, and transmits the occurrence information to the other central monitoring control device. The information is transmitted to and monitored by one device. In this way, remote equipment Rf
Memorize in advance the phone numbers of the central monitoring and control systems in other building groups that can be backed up, and be sure to automatically switch the phone numbers using the remote device in the event that your own central monitoring and control system malfunctions.

G. Example An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, A and B are centralized monitoring and control devices (hereinafter referred to as centralized centers) installed in different buildings,
sa and sb are telephone exchanges of public telephone lines in which centralized centers A and B are accommodated. This telephone exchange Sa, Sb
There are remote devices RMA, , RMA, . . . and RMB, , RMB installed in each building of the building group.

. . . are connected to each other via separate telephone lines. The remote devices RMA, , RMA, . The information listed includes electricity, air conditioning, disaster prevention, etc. Also, remote device R

In addition, the remote device RMA, , RMA,...
・The phone number of central center B is the remote device RMB.
, , RMBl...l The telephone number of central center A is stored in advance, and it also has a function to automatically switch the telephone number when central center A or B is out of order. .

In the embodiment configured as described above, the centralized center A
Suppose that something goes wrong. At this time, the remote device HMA auto-dials the telephone number of the centralized sensor A in order to transmit the information generated within the building to the centralized center A. However, if the centralized center A is out of communication and communication is interrupted, the pre-stored telephone number of the centralized center B is automatically dialed and the occurrence information is transmitted to the centralized center B.

As a result, the occurrence information is backed up.

Next, the operator of central center A informs central center B that central center A is out of order, operates central center B, and uses remote devices RMA, , RM of central center A.
A case will be described in which groups A, . . . are placed under the control of centralized center B.

When operating central center B (by dialing and connecting the remote devices RMA, , RMA, ... of central center A), the remote devices RMA, , RMAI, ...
. . . sends a command to switch the reading unit (not shown) of the telephone number stored as data to the calling telephone number side of the centralized center B. After this switching, the remote devices RMA, , RMB, . . . can dial and transmit the generated information to the central center B.

In addition to the above, when operating central center B, remote device RMA
, , RMA, . . . , central center B transmits the central center B's calling telephone number and rewrites the telephone number for calling central center A to that number. After rewriting, remote device RMA, , RMA,...
can transmit the occurrence information by dialing the central center B.

As described above, when centralized center A fails, backup processing is performed at centralized center B, but when the failure of centralized center A is recovered, the information accumulated in centralized center B is transferred to centralized center A#. Transfers can also be made via public telephone lines. Note that the restoration may be performed by performing an operation opposite to the above-mentioned means. That is, the telephone number for calling the center of the remote device from central center A is switched to that for central center A.

Thereafter, the telephone number for centralized center A is sent and rewritten.

FIGS. 2 and 3 are block diagrams showing other embodiments of the present invention, and FIG. 2 is an embodiment in which a backup system is used in which the central centers are sequentially visited when there are three or more centers. This second
In the figure, a telephone number is stored in advance in the remote device in order to back up a center preceding the own center. The operation at this time is similar to that of the previous embodiment. This embodiment is particularly effective when there is an odd number of concentration centers.

FIG. 3 shows an embodiment in which there is a management center 2 that supervises the centralized centers, and this FIG. 3 shows the centralized center A.

B and O are backed up by the computer 2 for management purposes. In the embodiment shown in FIG. 3, since information is transferred to the management computer 2, the cost for the backup function can be reduced.

In each of the above-described embodiments, the auto-dial number can be changed from the backup center by transmitting a telephone number switching command or by downloading the telephone number, and recovery can be done in the same way. Furthermore, since the data accumulated in the backup center is transferred to the original center after recovery, data loss does not occur.

Effects of the Hole Invention As described above, according to the present invention, a remote device in which the telephone numbers of one's own and other centralized centers are stored in advance and has an auto-dial function transmits the generated information to one's own centralized center. When transmission is impossible, the phone number of another centralized center is automatically dialed and the information is transferred to the other centralized center. It is possible to manage electricity, air conditioning, etc., and since there is no duplication, the equipment cost does not increase and the utilization rate of the equipment can be increased.
