Abstract

PURPOSE:To allow a supervisory personnel not resident always in a control center to confirm an event caused in the device even in a paging system possible for call only by allowing the supervisory personnel to carry a pager identification number (ID-No). CONSTITUTION:If a device alarm, for example, takes place in devices 3-6, the content is informed to the control center 1. In detecting the event, the content of event is stored temporarily to start a paging call/response telephone set 2 next. Then start is informed to a paging terminal 8 through an exchange 7 and a predetermined pager ID-No is dialed from the telephone set 2. The paging terminal 8 receiving it sends the ID-No from a transmitter 9. The pager possessor (supervisor) uses a pager 10 by generation of the event and makes a call to the telephone set 2. Then the control center replies the stored event content in voice synthesis.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote monitoring system, and particularly to a remote monitoring system using a paging system.

Traditionally, to monitor whether a system is working properly, wired or wireless lines are used to collect monitoring data from devices at a control center, making it possible to monitor devices even when they are far away from their locations. Systems that can do this are known. With this system, for example, even in systems where devices are scattered in multiple locations, there is no need to have a supervisor stationed outside of the control center, so the number of personnel can be reduced by one, allowing for efficient operation.

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

[Conventional technology]

Therefore, the inventor of the present invention aimed to eliminate this drawback.

Patent Application No. 59-257 filed on December 7, 1980.
No. 638 No. 9 In the title of the invention [Remote monitoring system using paging system].

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, the stored at least the predetermined pager identification number is stored. A paging system is incorporated into the remote monitoring device, so that a monitoring person who is not permanently stationed at the control center can take the paging system into the remote monitoring device. A remote monitoring system that automatically calls up the pager in the device, so that even if a monitor is not stationed at the control center, he or she can reliably know what is happening to the device.

Already proposed.

[Problem that the invention seeks to solve]

However, if the paging system you are trying to use is a paging system that only allows calls, such as one for public services (telephone company services), you can only call the pager. The disadvantage was that the observer could not know whether something had happened.

[Purpose of the invention]

Therefore, an object of the present invention is to provide a remote monitoring system that allows a monitor who is not permanently stationed at the control center to check the contents of events occurring in the device, even if the paging system to be used is a paging system that can only be called. This is what we are trying to provide.

[Means for solving problems]

One aspect of the present invention includes a first detection means for detecting a plurality of events, a first storage means for storing a predetermined pager identification number, and a first detection means for detecting a plurality of events in the first detection means. When any one of the plurality of events is detected, a second storage means stores the content of the detected event, and when any one of the plurality of events is detected in the first detection means, the first storage means stores the content of the detected event. means for transmitting the stored pager identification number to the wireless selective calling device via the paging call/response telephone; and a second means for detecting an incoming call to the paging call/response telephone from a general telephone or the like. detecting means, and when the second detecting means detects the incoming call, transmitting the event content stored in the second storing means to the paging call/answering telephone using a tone signal or a voice signal; This is a remote monitoring system that uses a paging system that includes means for sending information to the general telephone set or the like via a paging system.

Another aspect of the present invention is a first detection means for detecting a plurality of events, and a first storage means for storing a predetermined pager identification number.

When any one of the plurality of events is detected in the first detection means, a second detection means stores the content of the detected event.
storage means, and when any of the plurality of events is detected in the first detection means, the pager identification number stored in the first memory is transmitted via a paging call/answer telephone. a second detection means for detecting an incoming call from a general telephone or the like to the paging/answering telephone, and when the second detecting means detects the incoming call; , and fifth detection means for detecting a voice command from the general telephone or the like.

When the command is detected in the sixth detection means, the content of the event stored in the second storage means is transmitted to the general public via the paging call/answer telephone as a tone signal or voice signal. This is a remote monitoring system that uses a paging system with a means for sending data to a telephone or the like.

[For production]

According to such a configuration, by carrying a pager (wireless selective calling receiving device) with the above-mentioned pager identification number (hereinafter abbreviated as "No"), the monitor can travel to a place far from the control center. Even when the person is at home, he/she can know the occurrence of the above-mentioned event, and by calling the above-mentioned paging call/response telephone at the control center from the above-mentioned general telephone nearby,
The content of the event that occurred in the tone signal or voice signal can be known.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an example of the configuration of a remote monitoring device embodying the present invention.

When some event occurs in the devices 6 to B, for example, a device alarm, the content is notified to the control center 1. When the control center 1 detects the event, it temporarily stores the event contents and makes a paging call/
Activate the answering telephone (butsuhon telephone) 2 (off-hook) and connect the paging terminal (
Wireless selective discharge device) 8 is notified of activation.

A predetermined pager ID number is dialed from the paging call/response telephone 2.

The paging terminal 8 that received the dialed pager ID No.
is sent into the air from the transmitter 9 as a paging signal.

The pager owner (watchman) knows that some event has occurred when the pager (wireless selective calling receiver) 10 rings, and makes a paging call/response at the control center 1 from a nearby general telephone 11. call telephone number 2. When the telephone 11 is connected, the pager owner instructs the control center 1 to

,−,.

A voice says, "Nanigaokitaka?"

The control center 1 that detected this word responds by synthesizing the content of the temporarily stored event that triggered the sending of the pager ID number (for example, "Souchi No. 1 Koshiyou").

The pager owner can immediately see what the event is about.

Next, the operations of the control center 1 and the paging call/answer telephone 2 will be described in more detail with reference to FIG.

First, we will describe the operation from when an event is detected to when the pager is called. Events from devices 6-6 are:

Detected by event detection circuits 111 to 114, respectively,
The CPU 121 is informed through the system path 124 that an event has occurred. CPU that knows event detection 12

And pager 1D stored in RAM 122
No. System bus 124. A dial is made from the paging call/response telephone 2 through the button information signal generation circuit 134 (outgoing call). After dialing, the control center 1 puts the paging call/answer telephone 2 on-hook through the activation circuit 161. In addition, ROM12
3 stores a program for performing a series of these operations of the CPU 121.

Next, we will describe the operation when the pager owner recognizes the detection of an event by the sound of the pager and calls (receives) the paging call/response telephone set 2.

Incoming calls from the paging call/response telephone 2 are sent to the CPU via the ringing detection circuit 165 and the system bus 124.
121 will be notified. Upon learning of the incoming call, the CPU 121 uses the system bus 124. The paging call/response telephone set 2 is off-hook through the activation circuit 131 and waits for a command from a caller.

When the caller (pager owner) speaks the command "Nanigaokita-riki?", the CPU 121 activates the voice recognition circuit 162. Event inquiry commands are learned through the system bus 124. Next, the CPU 121 reads the RAM 1
The event number temporarily stored in 22 is transferred to the system bus 12.
4. Through the voice synthesis circuit 163, the paging call/response telephone 2 informs the caller of the event details by voice.

Note that if the incoming call detection is enabled only during the period from when an event occurs until a response is made, the paging call/response telephone 2 can be used as a general telephone at other times. Conversely, if it is always enabled, there will be no pager call, and even if the device is normal, its normal state can be confirmed by making a phone call. (If it is normal, another response will be made, for example, "Send a message.") In addition, in the paging/answering telephone 2, if the

212 is a speaker part of the receiver, 213 is a microphone part of the receiver, 221 is a button button DTMF signal generation circuit, 222 is a keypad for the button button, 23
1 is a protection circuit for voltage limitation, and 262 is a diode bridge to prevent reverse connection.

263 has one phosphorus circuit (bell), and 234 has a hook switch, which is almost the same as a regular telephone. Also, switch 241
．． 242, 243, 244, 245, 246 are switches for changing between the state of connection with the control terminal 1 (remote monitoring state) and the state of a regular telephone, and FIG. 2 shows the state of a regular telephone.

To enable remote monitoring, simply flip these switches to the opposite side.

The voice recognition circuit 162 is not particularly necessary, and the voice synthesis circuit 135 may be replaced with, for example, a tone signal generation circuit or a tape recorder.

〔Effect of the invention〕

In this way, if the present invention is used, a system will be created that can perform detailed remote monitoring even when using a call-only paging system such as the NTT (Nippon Telegraph and Telephone Public Corporation) wireless selective calling system. It can also be applied to home security systems, etc., where you can receive warnings such as alarms even when you are out.
