Abstract

PURPOSE: To attain quick processing on the occurrence of a fault by sending a fault signal directly to an automatic metering meter by a fault detector and sending the signal to a management center via an alarm device and an automatic metering system. CONSTITUTION: A fault detector 9 connects to a radio master set 5 via a communication line 10 and a fault signal is sent to an automatic metering meter 7 and a management center 1 via the radio master set 5. The alarm device 11 is connected to the fault detector 9, a T-NCU 4, the radio master set 5 or the radio slave set 6 directly or via the communication line 10. In this case, when the fault detector detects a fault, the signal is directly sent to an automatic metering meter 7 or sent via the radio slave set 6 or the radio master set 5. In this case, the signal is sent earlier to the management center 1, the management center 1 receiving the signal discriminates the content of a fault to control the automatic metering meter 7 so as to cope with a fault event.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of coping with an abnormality in a system for managing a management center and an automatic meter-reading meter to be managed by using a telephone line.

[0002]

2. Description of the Related Art Management information such as automatic meter reading meters for gas, water, electricity, vending machines, etc. is acquired via a telephone line, and various signals are transmitted from the management center to these terminal devices. Interactive communication management systems are known. As this type of management system, it is difficult to connect the terminal device directly to the terminal of the telephone line depending on the method of connecting the terminal and the management center with a telephone line and the installation condition of the terminal device. A system has been proposed in which a wireless slave device is attached to the side, a wireless master device is attached to the T-NCU of a terminal of a telephone line, and wireless communication is performed during this period. Also, a system is known in which, when an abnormal situation such as a fire or gas leak occurs in a consumer, these detectors drive an alarm device or notify the management center side.

[0003]

However, in the case of the above-mentioned conventional automatic meter reading and warning system, since each is individually systematized, the equipment is expensive and it may not be possible to quickly deal with it.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, and the constitution thereof is as follows. 1. When the abnormality detector detects an abnormality, it drives an alarm device,
At the same time, while using the automatic meter reading system to report to the management center side, how to deal with abnormalities in the automatic meter reading system that controls the automatic meter reading meter. 2. 1. The method for coping with an abnormality in the automatic meter reading system according to the above 1, wherein the abnormality detector is installed on the automatic meter reading meter or T-NCU side. 3. 1 or 2, wherein the T-NCU side is connected to a wireless master unit, and the automatic meter reading side is connected to a wireless slave unit. 4. In the above 1 or 2 or 3, the abnormality detector is provided with an abnormal signal transmitting radio circuit or an abnormal signal transmitting / receiving radio circuit, and the wireless automatic meter reading meter, the wireless slave device or the wireless master device is provided with an abnormal signal receiving circuit or an abnormal signal transmitting / receiving radio circuit. A method for coping with an abnormality in the automatic meter reading system provided with. 5. In 1 or 2 or 3 above, a method for coping with an abnormality in an automatic meter reading system in which an abnormality detector and an automatic meter reading meter, a wireless slave unit, or a wireless master unit are connected by an abnormal signal communication line.

[0005]

When an abnormal situation such as a fire or a gas leak occurs on the customer side and the abnormality detector detects this, an abnormality signal is transmitted from the abnormality detector. This abnormal signal is transmitted to the automatic meter reading meter, the wireless slave unit, the wireless master unit, or the T-NCU side via the communication line or the wireless, and also to the alarm device and the management center side. As a result, automatic stop of the automatic meter-reading meter, driving of the alarm device, and various actions at the time of abnormality on the management center side are performed.

[0006]

1 and 2 show an embodiment of the present invention. Reference numeral 1 is a management center, 2 is a telephone line, 3 is a switch, 4 is a T-NCU, 5 is a wireless master device, 6 is a wireless slave device, 7 is an automatic meter reading meter, 8 is a telephone device, and 9 is abnormality detection. The abnormality detector 9 is connected to the automatic meter-reading meter 7 through a communication line 10. When the abnormality detector 9 detects an abnormality, it sends an abnormal signal to the automatic meter-reading meter 7. Upon receipt of this abnormal signal, the automatic meter-reading meter 7 immediately stops its operation, and further issues an abnormal notification to the management center 1 side by automatic calling.
Further, an alarm device 11 is attached to the customer, and an abnormal signal is transmitted to this alarm device 11 at the same time. As a result, the alarm device 11 is driven. In addition, although the abnormality detector 9 is connected to the automatic meter-reading meter 7 in the case of FIG.
Alternatively, the wireless master device 5 may be connected to the communication line 10 or by a wireless communication system as shown in FIG.

FIG. 3 shows an embodiment in which the automatic meter reading meter 7 is directly connected to the T-NCU 4. In FIG. 4, the abnormality detector 9 is connected to the wireless master device 5 via the communication line 10, and the abnormality signal is transmitted to the automatic meter reading meter 7 side and the management center 1 side via the wireless master device 5. The alarm device 11 may be connected to the abnormality detector 9, the T-NCU 4, the wireless master device 5 or the wireless slave device 6 via the communication line 10, or only the alarm device 11 may be independently connected by a wireless communication method. May be. The mounting position of the alarm device 11 is a place or a plurality of places most easily noticed by a family member.

In the above embodiment, when the abnormality detector 9 detects an abnormality, the signal is transmitted directly to the automatic meter reading meter 7 or via the wireless slave unit 6 or the wireless master unit 5. , The management center 1 side is configured to be transmitted first, and the management center 1 that has received this signal determines the content of the abnormality, and based on this, controls the automatic meter-reading meter 7 to respond to the abnormal situation. You may do it.

[0009]

As described above, according to the present invention, the abnormality signal detected by the abnormality detector is sent to the management center side by directly controlling the automatic meter reading meter by using the automatic meter reading system, driving the alarm device, or the like. Since the notification is made, in the automatic meter reading system, it is possible to construct a system for coping with an abnormality at low cost, and it is possible to swiftly respond.
