Description

The present invention relates to a monitoring and reporting system.

There is known a monitoring / reporting system in which data to be monitored is taken into a monitoring / reporting device installed at the site, and the status of the monitoring target is transferred to a remote location by communication and displayed. For example, the monitoring and reporting system performs remote monitoring and control of water and sewage water supply and distribution equipment, industrial production equipment, sales data collection equipment, etc., and transfers data and reports warnings to users.

In such a monitoring and reporting system, in order to reduce communication costs, a communication line is often used each time a line connection is made only during communication such as a public telephone line instead of a constant communication line.

The monitoring and reporting system that uses the communication line each time enables the communication function only when an abnormality occurs at the site or when there is access from the outside, and the status of the site and the collected data are used as the monitoring and reporting device. Transmit or notify the user.

Even before network line services such as ADSL (asymmetric digital subscriber line) were provided, a monitoring system that communicates each time using a public line has been known (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2000-286998

In the monitoring and reporting system, data acquisition master unit and data acquisition slave unit are set between terminals, and by sharing monitoring data, data is lost when any terminal fails without installing a central server. prevent.

However, in the public line monitoring and reporting system, the connection between terminals is made by one-to-one communication each time. Therefore, when the failure reporting operation and the data sharing operation overlap, the data acquisition master unit of the public line monitoring / reporting system executes the reporting operation after the data sharing operation is completed.

However, the voice notification operation using the public line may require a predetermined time (for example, 10 minutes or more) to complete the notification. Therefore, when the data acquisition master unit detects an abnormality of the monitoring target, the next data sharing operation may not be started promptly.

An object of the present invention is to promptly perform the next data sharing operation when the data acquisition master unit detects an abnormality of the monitoring target in the monitoring / reporting system.

The monitoring / reporting system of one aspect of the present invention is a monitoring / reporting system in which a first monitoring / reporting device, a second monitoring / reporting device, and a reporting target device are connected via a public line, and the first monitoring / reporting system is described above. When the reporting device acquires monitoring data from the monitored device, shares the monitoring data with the second monitoring and reporting device via the public line, and detects an abnormality in the monitored device, the reporting device has an abnormality. The detection data is sent to the second monitoring / reporting device via the public line, and the second monitoring / reporting device is based on the abnormality detection data sent from the first monitoring / reporting device. It is characterized in that a report is sent to the report target device via a line.

According to one aspect of the present invention, in the monitoring and reporting system, when the data acquisition master unit detects an abnormality of the monitoring target, the next data sharing operation can be quickly performed.

It is a block diagram of the whole monitoring report system of an Example. It is a figure which shows the processing content of the data acquisition master unit at the time of data sharing. It is a figure which shows the processing content of the data acquisition slave unit during data sharing. It is a figure which shows the processing content of a data acquisition master unit when a data acquisition master station detects an abnormality of a monitoring target during data sharing. It is a figure which shows the processing content of a data acquisition slave unit when a data acquisition master station detects an abnormality of a monitoring target during data sharing.

As a monitoring / reporting system, there is a monitoring / reporting system that uses a mobile phone line in addition to a public telephone line. Unlike other communication lines, mobile phone lines use radio waves, so there is no need to install fixed communication lines such as telephone lines at the site. A monitoring and reporting system using a mobile phone line is very easy to introduce, can communicate with a mobile body such as in-vehicle equipment, and the communication cost is generally cheaper than that of a fixed line. For this reason, the demand for monitoring and reporting systems using mobile phone lines has been increasing in recent years. Currently, the demand for monitoring systems using public lines is decreasing due to the spread of inexpensive network line services.

However, the voice report function can directly report to the user's mobile phone. In addition, facilities such as water and sewage supply and water distribution facilities are often installed in the mountains. For this reason, it is often out of the range provided by the constant communication line and the mobile phone line. Under such circumstances, the monitoring and reporting system by communication using the public line is still receiving a certain demand from the market.

Therefore, in the monitoring and reporting system of the embodiment, in order to reduce the communication cost, a communication line is used each time the line is connected only during communication such as a public telephone line instead of the constant communication line.

In the monitoring / reporting system of the embodiment, in a public line monitoring / reporting system having a data server function for recording monitoring data to be monitored, a data acquisition master unit and a data acquisition slave unit are set, and a data acquisition slave unit is set from the data acquisition master unit. Data is shared by making a dial-up connection with a public line at regular intervals.

At this time, when the data acquisition master station detects an abnormality to be monitored, the data acquisition slave unit acquires the abnormality detection data of the data acquisition master unit, and after the data sharing operation is completed, the data acquisition slave unit becomes the data acquisition master unit. Performs a report operation instead. As a result, rapid continuation of data sharing operation and notification operation are realized.
Hereinafter, examples will be described with reference to the drawings.
