2. Description of the Related Art In a monitoring device for reporting a facility abnormality, intrusion, fire, or the like in a building or an apartment building to a monitoring center of a maintenance company or a security company through a telephone line, whether the operation of the monitoring device and the telephone line are normal. In order to check whether or not it is, a periodic alarm is actually issued at regular time intervals.
However, there is a phone fee for this regular alert. Especially,
At sites where intrusions and fires are monitored, the time interval for periodic alarms is short and telephone charges are considerable. The time interval of the periodic notification is, for example, every 24 hours to the monitoring center of the maintenance company, and every 108 minutes to the monitoring center of the security company. In the monitoring center, the method of checking for periodic alerts is not limited to the periodic alerts within the above-mentioned fixed time, but also normal processing is performed if there is any alert such as equipment abnormality, and if there is no alert, abnormality is detected. It is determined that there is, and a maintenance person is dispatched to the site to check the operation of the monitoring device. In addition, the judgment of abnormality is automatically processed by the built-in computer of the monitoring center. Also, the dispatch of maintenance personnel is instructed by the staff of the monitoring center based on the output of the computer.

FIG. 3 is a block diagram showing a conventional remote monitoring system. In FIG. 3, a monitoring device 1 for monitoring a monitored object is provided in a building such as a building or a condominium, and when it is determined that a facility failure or abnormality has occurred based on a facility monitoring input 5 and a crime prevention / disaster prevention monitoring input 6. , The signal to I / O
The signal input from the interface 7 is converted by the modulation / demodulation device 12, and the network control device 13 automatically makes a call, and issues a call to the monitoring center via the telephone network 2. In the case of the equipment abnormality signal, the alarm is sent to the monitoring center 3 of the maintenance company, and in the case of the crime prevention / disaster prevention abnormality signal, the alarm is sent to the monitoring center 4 of the security company.

The monitoring device 1 has a computer 11 as a processing device, and the computer 11 has a RAM as alarm storage means for recording alarm contents and the like.
8, a CPU 9 as an alarm control means, and a ROM 10 in which a program for controlling the operation of the monitoring device is stored. In addition to the generation of the above-described equipment abnormality signal and the crime prevention / disaster prevention abnormality signal, the monitoring device In order to check the operation of 1 and whether or not the telephone line is normal, the monitoring centers 3 and 4 are provided with regular alerts at different intervals.
Each of the monitoring centers 3 and 4 has a built-in computer similar to that of the monitoring device 1, a RAM serving as an incoming call storing means for storing an incoming call from the monitoring device 1, and a memory based on the stored incoming call content. C as an incoming call control means for checking the arrival of a scheduled alert and performing a response process when the scheduled alert is not received
A PU and a ROM for storing a control program are provided.

[0005] That is, in the monitoring device 1, in order to check whether or not the monitoring device 1 is normal and whether or not the telephone line network 2 is normal, a regular interval is sent to each monitoring center 3 or 4 at regular intervals. Reporting. First, the timer is counted by the computer 11 after the power of the monitoring device 1 is turned on. When the counter value has passed, for example, 10.8 minutes, a periodic alarm operation is started by a program stored in the ROM 10, a telephone call is automatically made by the network control device 13, and a telephone line is sent to the monitoring center 4 of the security company. Net 2
A periodic alarm signal is transmitted through. After transmitting the periodic alarm signal, the alarm content is recorded in the RAM 8. Further, when the counter value elapses, for example, 24 hours, a regular notification signal is transmitted to the monitoring center 3 of the maintenance company by the same operation. After transmitting the periodic alarm signal to the maintenance company monitoring center, the counter is reset, the timer starts counting again, and the same operation is repeated thereafter.

Next, the signal processing operation of the monitoring apparatus 1 and the respective monitoring centers 3 and 4 in the above configuration will be described with reference to a flowchart shown in FIG. First, a normal operation will be described. When an abnormality occurs in a building such as a building or a condominium based on the input of the equipment monitoring input 5 or the security / disaster prevention monitoring input 6 via the I / O interface 7 (S101), the CPU 9 of the monitoring device 1 issues an abnormality notification. At the same time (S102), the contents of the alert are recorded in the RAM 8 (S3).
01).

[0007] The CPUs of the monitoring centers 3 and 4 of the security company or the maintenance company receive the above-mentioned abnormal alerts (S
103) On the basis of this, an instruction is issued to dispatch a maintenance person to the site where the abnormality has occurred and to confirm it (S104). The received abnormality report is stored in the RAM (S302).

Next, the operation at the time of the periodic alarm check will be described. The CPU of the monitoring device 1 determines that the scheduled time has come (S
201) For example, the monitoring center 4 of the security company is notified at regular intervals of 108 minutes, and the monitoring center 3 of the maintenance company is notified at regular intervals of 24 hours to the corresponding monitoring center (S202). The content of the alert is recorded in the RAM 8 (S301). The CPUs of the monitoring centers 3 and 4 of the security company or the maintenance company receive the regular notification (S
203), and records the contents of the incoming call in the RAM (S30).
2). Then, at the time of the regular check (S30)
3) For example, once every 108 minutes at the monitoring center 4 of the security company, and once every 24 hours at the monitoring center 3 of the maintenance company.
At each time, the history of the incoming call is confirmed from the contents of the incoming call recorded in the RAM (S304).

If there is an incoming history, it is regarded that there is no abnormality (S3
07), normal processing is performed (S308). On the other hand, if there is no history of incoming calls, the monitoring apparatus 1 or the telephone network 2 is regarded as abnormal (S305), and the regular alert non-call processing is performed.
306). It should be noted that the incoming signal to be checked at the regular time is not limited to the signal of the periodic report, but may be any report such as a facility abnormality signal from the site. That is, if there is any alarm from the monitoring device 1 within a certain time interval, it is processed as if there is no abnormality.

[0010]

As described above, according to the conventional remote monitoring system, in the periodic check of the monitoring centers 3 and 4, some incoming history such as an abnormal equipment signal from the monitoring device 1 is detected within a predetermined time interval. If there is, it is determined that there is no abnormality in the monitoring device 1 and the telephone network 2. Therefore, if there is an alarm such as an equipment abnormal signal within a certain time interval, the periodic notification is unnecessary, but the periodic alarm is always emitted at a certain time interval, and as a result, unnecessary telephone charges Will occur.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems of the prior art, and has as its object to provide a remote monitoring system capable of efficiently reducing telephone charges which are increased due to periodic notification. .

The remote monitoring system according to the present invention has a function of confirming a past alarm history stored in the monitoring device, and stopping the periodic alarm if there is an alarm history. Also, if the monitoring center of the maintenance company and the security company are connected via a telephone network, and the regular alert does not arrive at the self-monitoring center, the history of incoming calls at other monitoring centers is checked. The same processing is performed as when the regular alert arrives. With the above function, the conventional monitoring apparatus always issues a periodic alert, but the present invention has the effect of reducing the number of regular alerts and reducing telephone charges.

FIG. 1 is a block diagram showing a remote monitoring system according to a specific embodiment of the present invention. In FIG. 1, reference numerals 1 to 9 and 11 to 13 are the same as those in the conventional example, and thus description thereof is omitted. As a new code, reference numeral 14 denotes a telephone network (dedicated line) for connecting the monitoring centers 3 and 4 of the maintenance company and the security company so that the history of incoming calls between the monitoring centers can be referred to each other. The telephone network 2 may be used without newly providing the telephone network 14.

In this embodiment, the program stored in the ROM is changed, and the CPU 9 as the alarm control means of the monitoring device 1 causes the monitoring center 3, 4 of the maintenance company or the security company to issue the periodic alarm. At regular intervals, the regular alarm is confirmed based on the past alarm history stored in the RAM 8 as the alarm storage means, and the monitoring center of the maintenance company or the security company is checked within the past time corresponding to the regular alarm interval. A function has been added so that when a regular alert is issued to any of the monitoring centers 3 and 4, a regular alert to another monitoring center can be stopped. The CPU as the incoming call control means of the own monitoring center based on the past incoming history stored in the RAM as the incoming call storage means of the own monitoring center at regular time intervals for the own monitoring center. Check the incoming of the regular alert, and if there is no incoming call, check the past incoming history stored in the RAM of the other monitoring center, and receive an incoming call within the past time corresponding to the regular alert interval to the own monitoring center. A function has been added that can determine that there is no abnormality in the regular alert to the self-monitoring center when there is a warning.

Next, the signal processing operation of the monitoring apparatus 1 and the monitoring centers 3 and 4 in the above configuration will be described with reference to the flowchart shown in FIG. First, the normal operation is
This is the same as the conventional example. That is, the CPU 9 of the monitoring device 1
Is the equipment monitoring input 5 via the I / O interface 7
Or, when an abnormality occurs in a building such as a building or a condominium based on the input of the crime prevention / disaster prevention monitoring input 6 (S101),
An alarm is issued (S102), and the contents of the alarm are stored in the RAM 8.
(S301).

The CPUs of the monitoring centers 3 and 4 of the security company or the maintenance company receive the above-mentioned abnormal alerts (S
103) On the basis of this, an instruction is issued to dispatch a maintenance person to the site where the abnormality has occurred and to confirm it (S104). The received abnormality report is stored in the RAM (S302).

Next, the operation at the time of the periodic alarm check will be described. The CPU of the monitoring device 1 determines that the scheduled time has come (S
201) For example, the alarm history stored in the RAM 8 is checked at intervals of 108 minutes for the monitoring center 4 of the security company and at intervals of 24 hours for the monitoring center 3 of the maintenance company (S701). When the alarm is issued to the monitoring center 4 of the security company, the alarm history within the past 108 minutes is checked, and if there is any alarm history, the periodic alarm is stopped (S70).
2 → S703 → S705). If the report destination is the monitoring center 3 of the maintenance company, the report history is confirmed within the past 24 hours, and if there is any report history, the regular report is stopped (S702 → S704 → S705). In any case, if there is no alarm history, a periodic alarm is issued (S202), and the alarm content is stored in the RAM 8 (S301).

The CPUs of the monitoring centers 3 and 4 of the security company or the maintenance company receive the periodic report (S203) and record the contents of the incoming call in the RAM (S302). And
At the time of the regular check (S303), for example, the data is recorded in the RAM of the self-monitoring center at the monitoring center 4 of the security company once every 108 minutes and once every 24 hours at the monitoring center 3 of the maintenance company. The incoming call history is checked from the incoming call contents, and the security company's monitoring center 4
Then, if there is an incoming history within the past 108 minutes and the monitoring center 3 of the maintenance company within the past 24 hours, it is assumed that there is no abnormality and normal processing is performed (S309 → S401 → S603 → S
604, S309 → S501 → S603 → S604).

On the other hand, in the RAM of the self-monitoring center, if there is no incoming call history within the past 108 minutes at the monitoring center 4 of the security company and within the past 24 hours at the monitoring center 3 of the maintenance company, each of the other Monitoring Center RAM
Is confirmed via the telephone network 14 and the incoming call history of the other monitoring center is received when there is an incoming call within the past time corresponding to the regular alerting interval of the own monitoring center. It is assumed that there is no abnormality in the report and normal processing is performed (S309 → S401 → S402 → S403 → S6)
03 → S604, S309 → S501 → S502 → S5
03 → S603 → S604).

At this time, if the RAM of another monitoring center
Is checked via the telephone network 14 and if there is no incoming call within the past time corresponding to the regular alerting interval of the self-monitoring center in the incoming call history of other monitoring centers, monitoring is performed. The apparatus 1 or the telephone line network 2 is regarded as abnormal, and the scheduled alert / non-call processing is performed, the monitoring center staff confirms and dispatches the maintenance staff to confirm the site (S4).
02 → S403 → S601 → S602, S502 → S5
03 → S601 → S602).

Therefore, according to the above-described embodiment, the monitoring device 1 is provided with a function of referring to the past alarm history at the time of the periodic alarm and stopping the periodic alarm if there is any alarm history within a predetermined time. Also, if there is no incoming history from the monitoring device 1 at the time of the periodic alert check, the monitoring centers 3 and 4 of the maintenance company and the security company refer to the incoming history of the other monitoring center via the telephone network 14 and determine the past. If there is a history of incoming calls within the time, the self-monitoring center is provided with a function to handle the occurrence of an alert, so that the number of regular alerts can be reduced and telephone charges can be reduced.
