Abstract

PURPOSE:To obtain a system with comparatively low cost and high reliability by providing a standby power supply with a comparatively small capacity to a slave station, notifying the occurrence of power failure to a master station with high reliability, collating present information with information just before the power failure at the restoration of power failure and restarting the supervisory function. CONSTITUTION:The system consists of slave stations 2 collecting alarm data from plural sub slave stations 3 and a master station 1 collecting alarm data from plural slave stations 2 and giving processing to each alarm. If power failure takes place in a slave station 2A, a power switching section SE detects it and a main power supply MS is switched immediately into a standby power supply PS. Then a telephone number of the master station 1 is sent from a control section CT by automatic dialing and redialing is repeated until the station is connected with a limit of number of times set depending on the capacity of the standby power supply PS. When the connection is confirmed, the slave station 2A entering the halt state due to the power failure is informed to the master station 1. After the end of notifying the power failure, the power of the slave station 2A is switched from the standby power supply PS into the main power supply MS, and awaits the power restoration while stopping its function. Since a memory M keeps the information of sub slave stations 3 just before the power failure, the function is continued by the standby power supply PS.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a notification management system using a telephone line, and particularly relates to a dial notification υ1@ system when a power outage occurs.

(Prior art) Figure 2 is a system diagram of a general notification management system, where 1 is a master station, 2 is a slave station, 3 is a substation, and A, B, and C are alarm sensors for gas leaks, crime prevention, etc. It is.

Each substation 31 to 3Il of the person in charge 83 is a residence information board installed in each residence, and each alarm sensor Δ.

A change in the status of B and C is automatically reported to the slave station 2 each time. Each of the slave stations 21 to 2o of the slave station 2 has a monitoring transmission WAr installed in each housing group, and each slave station 21 to 2o is notified via each line 41 to 4o of the telephone line 4. Alarm sensors A and B.

Information on the state change of C is automatically reported to the master station 1.

The master station 1 centrally manages housing groups dispersed in each area, is uninterrupted by a standby power supply, and takes actions in response to alarms automatically reported from each slave station 21 to 2n. .

On the other hand, regarding the slave station 2 and grandchild station 3, power outage is handled by the following methods according to the required functions of each system.

First of all, as a first method, the slave station 2. The grandchild station 3 unconditionally stops its function and immediately returns it when the power is restored.

The second method is to use the power outage slave station 2. Substation 3 unconditionally suspends its functions. However, child 82. In order to check the operating status of the grandchild station 3, the master station 1 can frequently call the slave station 2 to collect information, or the slave station 2 can periodically transmit the information.

As a third method, the slave station 2. The entire system, including substation 3, will be made uninterrupted. This method is carried out by equipping the slave station 2 with a backup power source of a predetermined standard based on the provisions of "Ministry of Home Affairs Ordinance No. 19, Article 4-8".

(Problem to be Solved by the Invention) However, in order to deal with a power outage in a slave station or a grandchild station, for example, according to the first method described above, it is not necessary to provide an uninterrupted power outage for both the slave station and grandchild station, so it is possible to reduce the cost. However, the system lacks reliability because the master station cannot monitor power outages of the slave stations.

In addition, according to the second method, it is possible to monitor slave stations, but the operating cost is high because telephone lines are used even when there is no change information.

According to the third method, the reliability of the system is high, but the initial investment amount is large.

As described above, there is a problem in that an attempt to improve system reliability increases operational costs or initial investment.

The present invention focuses on important functions for dealing with power outages, and assumes that during a power outage, related equipment also stops, so it is unavoidable that the system in the area stops.
To provide a system at a low cost that is automatically notified that a function will stop during a power outage and can reproduce the state before the power outage when the power is restored.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a substation installed in each dwelling unit to which an alarm sensor is connected, and alarm data of a plurality of substations. In a notification management system consisting of a slave station that collects alarm data and a master station that collects alarm data of multiple slave stations and takes action on each generated alarm,
Each slave station has a reserve of capacity required for a limited number of notifications @7t
& source, a memory which is made uninterruptible by the primary source and holds information of the secondary stations, and a slave station's power source are mutually connected to the main power source and the backup Mm. It is equipped with a power supply switching unit that switches the IJ, and when a power outage occurs in the slave station, the slave station is
After switching to the A power source, the main station is automatically dialed up to the number of re-dials set according to the capacity of the backup power source to report the power outage, and the state change data during the power outage is sent to the installed power source. This is to notify the parent station.

(Function) According to the present invention, when a power outage occurs in a slave station, the slave station is switched to the backup power supply, and the master station is called by automatic dialing with a limit of re-dial failures depending on the capacity of the backup power supply, and no response is received. If there is, a power outage will be reported.

When power is restored, the information collected in the memory just before the power outage is reported to the master station, and normal monitoring operations resume.

(Implementation V/4) Figure 1 is a block diagram of a notification management system showing one embodiment of the present invention, and parts equivalent to the system diagram in Figure 2 are designated by the same reference numerals and their explanations are omitted as appropriate. .

In the figure, 2Δ is a slave station, and its connection relationship with the master station 1 and grandchild 83 is the same as that of the slave 82 in FIG. MS is the main power supply, PS is the backup ffi source, and the main power supply MS is used in the event of a power outage.
Act on your behalf. The CT is a control unit that collects each data of each alarm sensor A, B, and C from the substation 3 and transmits it to the master station 1, and when a power outage occurs, pre-fi! When the number of re-dials is set according to the capacity of the power supply PS, or the capacity is detected and the number of re-dials is set as a limit, the master station 1 is automatically dialed to report a power outage, and when a TI call is made. Master station 1
The main station 1 automatically dials to report the power restoration, and also transmits information on changes between the data collected immediately before the power outage and the current data to the master station 1. The memory M is controlled by the control unit CT, and sequentially stores the current data of the sensors A, B, and C.
When the power is restored, it is also used as a transfer buffer for storing the change information. The SE constantly checks the single power supply MS at the power supply switching section, and when a power outage occurs,
Immediately switch and connect the control unit CT from the terminal t1 of the main power supply MS to the terminal t3 of the standby power supply PS, and! l11M
When a power outage is reported from the first CT to the master station 1 or a power failure is dialed the predetermined number of times, the control unit CT is connected to the terminal t2 and disconnected from the main power supply MS and the standby power supply PS, and when the power is restored, the main power supply Restore connection to MS. The power supply switching unit SE also connects the memory M to either the terminal t1 of the main power supply MS or the terminal t3 of the standby power supply PS to provide uninterrupted power supply.

FIG. 3 is a flowchart of the operation of the slave station 2A in the notification management system of FIG. 1, and this series of operations will be explained below.

In the slave station 2A, when a power outage occurs, the power supply switching section SE detects this (step 81) and immediately switches from the main power supply MS to the standby power supply PS (S2). Then, in order to notify the master station 1 that a power outage has occurred, the control unit CT sends the telephone number of the master station 1 to the automatic dial by full (S3), and the connection is confirmed (S4). If the connection cannot be confirmed, the call will be hung up and then dialed again after a while. The number of re-dials is planned! The process is repeated until the connection is made, up to the number of times set according to the capacity and weight of the i-power source PS (S5). When the connection is confirmed, the master station 1 is notified that the local station is in a stopped state due to a power outage (S6
). Note that from now on, the master station 1 takes a system corresponding to the power outage of the slave station 2A. After reporting the power outage, slave station 2A switches to the standby power supply PS.
The power source MS is switched from the power source MS to the main power source MS (S7). The slave station 2A stops functioning and waits for power restoration (S8). The memory M maintains the information of the substation 3 immediately before the power outage, so it continues to function by pre-ordering 'IQps'.

Due to the power restoration, the power reset of the slave station 2A is canceled, the slave station 2A resumes its functions (39), and the control unit CT
The current state information of the current state is collected, the change data is compared with the state before the power outage, and the change data is filed in a transfer buffer (not shown) in the memory M (810). Then, the control unit CT automatically dials the master station 1 (511), and when the connection is confirmed (S12), the master station 1 is notified that 11 calls have been made, and change information during the power outage is transmitted (S13). , returns to normal monitoring operation (S14).

(Effects of the Invention) As explained above, according to the present invention, by equipping the slave station with a relatively small backup power supply, the master station is notified of a power outage with high reliability, and the power is restored. Sometimes, the information immediately before a power outage is compared with the current information to restart the monitoring function, so a highly reliable system can be obtained at a relatively low cost.
