Abstract

PURPOSE:To efficiently and accurately perform monitor by detecting the signal indicating the abnormality of an electric apparatus to automatically call the telephone having a preliminarily registered telephone number and detecting that the receiver is hooked off to transmit details of the abnormal state. CONSTITUTION:A control part 3 of a monitor part detects the state of an apparatus 1 to be monitored: and if it is in the abnormal state, transmission destinations registered in a storage part 4 in the control part 3 are taken out in accordance with priority level and are called. When a line is established, the control part 3 requests a password after using a voice to inform the terminating side that this call is transmitted from the monitor part and the abnormal state occurs. If a registered password and the received password coincide with each other as the result of collation, the apparatus to be monitored which the abnormal state occurs in and the time when it occurs are reported with a voice. In the terminating side, states of apparatus to be monitored can be heard repeatedly on demand.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a remote monitoring system for general electrical equipment using a telephone line.

(Prior Art) Conventionally, in remote control systems using telephone lines, the operator can only grasp the status of the target device by sending a call to the control device of the target device. It was not possible to know the situation at the time the abnormality occurred. Furthermore, in order to know the status of an abnormality when it occurs, it is necessary to use a dedicated line, provide a transmission path between the control side and the controlled side, and constantly transmit a signal indicating the status. but,
The disadvantage of using a leased line is that it increases costs.

In order to avoid this drawback, in recent years, Japanese Patent Laid-Open No. 11j,
, No. 50-138280 "Remote control monitoring method" is known. In this method, a single dedicated line is used to transmit monitoring information to the controlled side during the idle time of the line, which occurs while the control signal is being transmitted from the control side to the controlled side, which occurs intermittently. It is transmitted from the control side to the control side.

(The problem to be solved by the invention) In the above-mentioned method, the notification of abnormal conditions is realized at a lower cost by using a dedicated line, but since the dedicated line is used, monitoring is possible. places are restricted. Furthermore, if monitoring is attempted from multiple locations, the cost required to install transmission lines becomes extremely large, and since terminals are used, there are disadvantages in that the monitoring requires manpower. Furthermore, there is no record of what conditions occurred and who verified them.

It is an object of the present invention to efficiently and accurately monitor target electrical equipment in a remote monitoring system, regardless of location, and to provide notification in an easy-to-understand manner, and to notify when an abnormal state occurs and who should know when. The purpose is to clarify whether verification has been carried out.

(Function) In the present invention, by combining pre-registered voices according to the situation, and recognizing the pre-registered call destination, notification of an abnormal condition is performed by remote monitoring, and the notification is sent via a telephone line. Input guidance and information notifications are provided by voice.

Therefore, according to the present invention, the operator at the destination is shown the timing to input operation instructions, and can hear by voice what operations are possible. Therefore, even operators who are unfamiliar with remote monitoring systems can use the interactive system. Furthermore, since a telephone line is used, the call destination can be anywhere as long as there is a telephone, and it is easy to register multiple locations. Furthermore, since the operator is alerted by the ringing tone of the telephone and is notified of the abnormal condition by voice, the operator does not need to constantly monitor the situation.

(Embodiments) Next, preferred embodiments of the present invention will be specifically described with reference to the accompanying drawings.

A transmission command is issued according to the information regarding the control operation of the part. Subsequently, the control operation of the storage part in the PB double signal control unit 3 sent from the called side is compared, and a control signal regarding audio transmission to the called side is issued. The receiving side is also checked to see if the call has been correctly received at the pre-registered destination, and the pre-registered destination is notified of the status of the electrical equipment 1, and the call is terminated. The abnormal state of the electrical equipment 1 and the history of calls and notifications are recorded in the storage device 4.

Next, the operation of this embodiment will be explained with reference to FIG.
.

First, the control section 3 of the monitoring section detects the state of the monitored device (FIG. 2, 101). If the detected state is not an abnormal state (not an abnormal state in FIG. 2 102), the control unit 3 repeats the state check of the monitored equipment (FIG. 2 101).
). If the detected state is an abnormal state (second
In the case of an abnormal state in FIG. 102), the control section 3 retrieves the destinations registered in the storage section of the control section 3 according to the priority order and sets the destinations (FIG. 2, 103). Once the destination is determined, the call is made (104 in FIG. 2). It is detected that the receiver of the destination telephone is lifted, and the line is established. If the line is not established (105 in Figure 2), the call is interrupted (11 in Figure 2).
0). If the number of interrupted calls is less than a certain number of times for the same destination, (3 in 107 in Figure 2)
If the number of calls is less than 10 times), try the call again. (Figure 2 1
Return to 04). If the number of call interruptions is less than a certain number of times (
107 in FIG. 2), reset the destination with the next priority after the current destination (FIG. 2 10).
Return to 3. ) When the line is established (when the line is established at 105 in FIG. 2), the control unit 3 sends a voice message to the called party to the effect that this call is from the monitoring unit and that an abnormal condition has occurred. and then requests a password (108 in Figure 3). The control unit 3 compares the received password with the password registered in combination with the destination in the memory part of the control unit 3, and if the received password does not pass (see 109 in Fig. 2), the received password is verified. (if not)
, if the number of failures is less than a certain number (less than 3 times in Figure 2 110), the password is requested again (
(Return to FIG. 2 108). If the number of failures is not less than a certain number (not less than 3 times in 110 of Fig. 2), a voice notification will be given that the password is incorrect and the line will be disconnected (111 of Fig. 2), and the next caller of the current destination will be notified. The destination with priority is reset (return to 103 in FIG. 2). If the password verification is successful (in the case where the password verification is successful in 109 in FIG. 2), a voice notification is given as to which of the monitored devices has caused an abnormal state and when (FIG. 2 112). When the password verification passes, the control unit 3 assumes that the abnormal state has been notified to the authorized notification destination, and in accordance with the priority order,
The call after changing the destination ends. The called party can repeatedly listen to the status of the monitored device as many times as necessary (FIG. 2, 114).

Regarding this embodiment, (1) In the above description, all transmissions from the control unit 3 to the called party are transmitted to the called party by voice via the voice response device.

■Since audio combinations are set using software, changes are easy and flexible.

■For the destination, set the phone number of the destination and set a password accordingly.

■It is possible to set multiple destinations.

■Destination phone numbers and passwords are set using software, making them easy to change and flexible. Furthermore, the number of destinations to be registered and the number of digits in the password can be freely set.

■The receiving party can confirm the caller by voice, and when PB double signal input is required, the input guide shows the necessary information and input timing, making it easy to operate even for users who are inexperienced with operations. can.

■If you make a mistake in an operation, the monitoring unit will send a voice message to the effect that the operation has been interrupted, prompting you to re-enter, and allowing you to continue the operation.

■When the monitoring unit is waiting for the PB double signal input from the receiving side,
If there is no input from the called side for a certain period of time or more, the line is disconnected by the monitoring unit. Since this time is set by software, it can be set freely.

■When an abnormal condition occurs, record the history of what caused the abnormal condition and when.

[Stocks] Automatic call is made, and the history until the notification of the abnormal condition ends is recorded every time one operation is completed.

11 In this embodiment, the call was terminated when the abnormal condition was notified to one of the authorized destinations, but the software settings may not allow the call to be made and notification to all registered destinations. It is also possible to keep a history of whether or not the data was received.

Next, a specific example of repetition will be explained.

Here, the electrical devices to be monitored include a glass breakage alarm system in a remote office, an emergency button, and an intruder detection device installed at the entrance. The explanation will be given by taking as an example a case where a notification is sent to a destination that has been sent, but the same applies when monitoring other electrical equipment.

First, when an abnormality occurs in the glass breakage alarm system, the control unit detects the condition and records what and when the abnormality occurred in the storage device.

Next, set the destination. A plurality of destinations are registered in advance, and priorities are set. First, select the destination with the highest priority among the destinations, and set the destination's phone number.

A call is made to the destination set in the above procedure, and if the destination is busy with another person or the destination is not found when called, the call is made again up to three times. If the line between the destination and the monitoring unit is still not established after making three calls, select the destination with the next highest priority after the current destination,
Set the destination phone number, and then repeat the call by changing the destination one after another until the line is established.

When the line is established, it is announced that the source is the monitoring unit for remote monitoring, and it is notified that an abnormal condition has occurred.

Next, it sends a message saying ``Please enter your PIN'' and prompts you to enter your password.

If the password is not registered together with the received PB double signal and the destination phone number (in this case, you will be prompted to enter the password again).

If a PB double signal different from the registered password is entered three times, a message saying ``Password is incorrect. The service will be terminated.'' After sending a message such as J, the line will be disconnected and the current call will be terminated. Select the destination with the next highest priority, and repeat the same operation by setting the destination again.

When a regular password is received, it is assumed that the abnormality has been notified to the regular destination, and the call is not made to a destination with a priority lower than the current destination.

Next, [What month, day, hour, and minute, the glass breakage alarm system is transmitting an abnormality. ” will be sent. Here, we have taken an example in which only the glass breakage alarm device has experienced an abnormality, but if multiple devices are in an abnormal state, each of them will be notified in the same way.

When the abnormal condition notification ends, [If you want to hear it again, click "
1#Pa, press 1Mtl to exit. Send an operation guide that means j.

When the PB double signal "1#'" is received, the message notifying the above-mentioned abnormal condition is sent again and the operation guide is repeated.

When a PB double signal of +12 +11 is received, the service will be terminated. ] and disconnects the line.

If you receive a PB signal other than ``1#'' or l+2#l+, the message "The number is incorrect. Please try again."
Send a message saying this and return to the operation guide.

The above is one specific example of this invention. The type of equipment to be monitored can be easily changed or added as long as it is an electrical equipment, and remote monitoring is possible using the same method.

(Effects of the Invention) As described above in detail, the present invention is a remote monitoring system that can be easily used even by users who are not familiar with the system by prompting voice input from the monitoring unit. On the other hand, if an abnormal condition occurs, the appropriate contact information is called by telephone and the status is notified, so there is no need to constantly monitor the equipment. Moreover, since calls are made to multiple locations in sequence until contact is established, notifications can be sent more efficiently and quickly. Furthermore, since a public line is used, remote monitoring can be realized at a lower cost than using a dedicated line, and the range of destinations can be expanded. Additionally, since the destination is verified using a password, more accurate notifications can be expected.
