Abstract

PURPOSE:To grasp an event without residing in a center by storing in advance information containing a pager identification number which has been determined in advance, and sending out the identification number to a paging terminal, when some event has been generated in a device. CONSTITUTION:A control center 5 starts a paging call use automatic calling telephone set 6, when some event which has occurred in devices 1-4 is detected. The telephone set 6 informs the start to a paging terminal 8 through a switchboard 7. Subsequently, the center 5 converts message information corresponding to an ID number of a paper, which has been determined in advance, and the event, to dial signal information, and sends it to the telephone set 6. The telephone set 6 converts it to a dial signal and sends it to the terminal 8. The terminal 8 receives a received terminal signal as the page ID number and the message information, converts it to a paging code and sends it out in the air through a transmitter 9, and informs the event of the devices 1-4 to a manager having a pager of a specified ID number.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to remote monitoring systems.

[Prior art and its problems]

Conventionally, to monitor whether a system is working properly, wired or wireless lines are used to collect monitoring data from devices at a control center.

There are systems that can monitor each device even when it is away from its location. With this system, for example, even in systems where devices are scattered in multiple locations, there is no need to have a manager stationed anywhere other than the control center.
It is possible to reduce the number of personnel and achieve efficient operations.

However, even with the above system, a manager must be permanently stationed at the control center, which is a major drawback in practice.

[Purpose of the invention]

Therefore, an object of the present invention is to provide a remote monitoring system in which a manager can reliably know events occurring in a device even if he is not permanently stationed at the control center.

[Structure of the invention]

In the present invention, in order to eliminate this drawback, a paging system for public services (telephone company services) or for private use within the system is embedded in the remote monitoring device, so that when something happens to the device, it is not resident in the control center. The pager that the administrator has is automatically called up.

According to the present invention, event detection means for detecting a plurality of events and information including at least a predetermined pager identification number are stored, and when the event detection means detects the event.

and memo 1y control means for sending the stored at least predetermined identification number to a paging terminal. A remote monitoring system using a paging system is obtained. Note that the information may be information about only the predetermined pager identification number, or may be information about the pager identification number that corresponds to at least two of the plurality of events, and furthermore, the information may be information about only the predetermined pager identification number. The message information may be an identification number and message information corresponding to the detected event.

〔Example〕

FIG. 1 is a diagram showing an example of the configuration of a remote monitoring device to which the present invention is applied. This embodiment uses pagetem. In a paging system with a message, by inputting a pager identification number (hereinafter abbreviated as ID No.) and message information into a telephone or an input terminal as input information, a pager with the specific ID No. is called up, and the message Information is displayed on a pager.

Now, in FIG. 1, when some event occurs in the devices 1 to 4, for example, when a device alarm is activated, the content is notified to the control center 5. In this case, this notification method prepares as many lines as the number of events, and when an event occurs, it gives the line an alert. When the control center 5 detects the above-mentioned event, it activates (off-hook) the automatic calling telephone 6 for paging calls (off-hook). Selective calling device) 8 is notified of activation.

Next, the control center 5 sends the pager I set in advance to the automatic calling telephone 6 for paging calls.
The D No. and message information corresponding to the event are converted into dial signal information (gutshuphone pushbutton information) and sent. The automatic calling telephone 6 for paging calls converts the dial signal information into a dial signal (DTMF signal) and advances it to the paging terminal 8. The paging terminal converts the received terminal signal into the pager-IDN.
o. Receive the message as message information, convert it into a paging code, send it to the air through the transmitter 9, and send it to the air using the specific ID.
The manager holding the pager No. is notified of events that have occurred in the devices 1 to 4.

FIG. 2 depicts the control center 5 and the automatic paging telephone 6 in more detail. Event 1 detection circuit 11 to event 4 detection circuit 14 are prepared as many as the number of events to be monitored, and notify the memory/control circuit 15 when each event is detected. The memory/control circuit 15 has a predetermined pager IDN.
o, and message information corresponding to the event are stored, and the pager ID is stored in accordance with the notified event.
No. and the message information are sent to the dial signal information generation circuit 16. The dial signal information generation circuit first gives off-hook information to the hook switch, then pages the pager ID number and message information one digit at a time as dial signal information (push button information of 4 waves in the low group and 3 waves in the high group). It is sent to the automatic calling telephone 6 for calling. The paging system used in this case may be for public service (telephone company service) or may be for private use within the system.

In the above embodiment, a paging system with a message is used, but a paging system with only a call without a message may also be used. Furthermore, by having at least two pager ID numbers corresponding to detected events, multiple events can be classified and notified by event to managers who have at least two pagers. This makes it possible to carry out appropriate checks quickly. In this case, it is preferable to have message information.

Needless to say, it may be only a call. Further, although in the above embodiments a telephone is used to enter the call into the paging terminal, the call may be entered directly into the paging terminal.

〔Effect of the invention〕

As can be seen from the above description, according to the monitoring system of the present invention, events that occur in the device are reliably communicated to a manager who is not resident at the control center. Application examples of the present invention include, in addition to large systems such as online systems, home security systems that allow you to know alarms such as fires and windows even when you are not at home, monitoring systems in factories and buildings, etc. Can be applied to various fields.
