Abstract

PURPOSE:To inform monitored contents such as abnormalities of the person in charge of monitoring securely by repeating communicating actions until an answering signal is returned from the prescribed communicating destination. CONSTITUTION:When in a device to be monitored, abnormalities occur, monitor inputs Ki(i=a-n) are set to on. A communicating decision circuit 6 decides establishment of communicating conditions in accordance with the inputs Ki, and transmits a signal output to a CPU1, which dials the prescribed communicating destination. When the CPU1 detects that a receiver has been picked up at the communicating destination, the CPU1 transmits abnormality generation order signals Pi(i=a-n) to a sound generation circuit 4 to generate a sound signal. When the person in charge of monitoring at the communication diestination receives the information, depresses prescribed pushbuttons and transmits an answering signal, the answering signal is received through an answering detection circuit 5. The circuit 6 deletes the establishment of communicating conditions, but a communicating action is repeated until the answering signal is received.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a reporting device that reports monitoring status to a designated reporting destination via a telephone line.

[Prior art]

Conventionally, as this type of reporting device, there is one shown in FIG. 1, for example.

This notification device operates as follows in the case of automatic notification.

A computer (hereinafter referred to as "CPU") (1) that controls the entire device operates a dial setting switch ( After reading the reporting telephone number set in step 2) and energizing the network control relay S of the network control circuit (3) to turn its contact e on (a side), the relay for pulse signal generation is activated. The DP is controlled and the contact point DP is turned on and off the number of times corresponding to the telephone number of the destination.

Then, the telephone line is connected to the destination and the polarized relay E
operates and its contact e turns on, the CPU (1
) activates the transmission/reception switching relay CML and turns its contact cml on (a side) to turn on the sound generation circuit (4).
is connected to the line via the freewheeling transformer T of the network control circuit (3).

Thereafter, the CPU (1) outputs the abnormality alarm command signal Pi to the sound generation circuit (4), which causes the sound generation circuit (4) to generate, for example, a sound signal such as "Device Noi has failed." When this voice operation is finished, or when the called party disconnects the telephone line, the relay F for detecting the called party's response is deactivated, and the CPU (1) detects the open circuit of the contact f. Deactivate relay CML to disconnect the device from the line.

However, conventional reporting devices are configured to unilaterally report when a user picks up the phone at a designated destination, regardless of the number of people on the other end. There were concerns that appropriate measures and treatment would not be taken despite reporting an abnormality.

[Summary of the invention]

The present invention was made in consideration of the above-mentioned problems, and an object of the present invention is to provide a reporting device that repeats the reporting operation until the notification can be sent to a person who can understand the content of the report and respond appropriately.

[Embodiments of the invention]

Hereinafter, the present invention will be described with reference to the block diagram in FIG. 2 and the flowchart in FIG. 3.

In Figure 2, parts that are the same or have the same effect as in Figure 1 are indicated by the same symbols, and (5) is a response signal sent when a person responsible for monitoring receives a report at a specified report destination. (6) is the monitoring input Ki
This is an alarm determination circuit that determines whether or not an alarm is necessary based on the response signal and the above-mentioned response signal. The response detection circuit (5) is a telephone line,
A filter (5) filters only frequency components pre-assigned to the response signal received via the network control circuit (3).
a) and a transistor (5b) that drives the output of the filter (5a) and sends it to the alarm determination circuit (6). The alarm determination circuit (6) is set by the monitoring input Ki, reset by the output of the transistor (5b), and consists of a group of flip-flops (6a) to (6n) that send the output to the CPU (1).

Next, the operation of the apparatus of this embodiment will be explained based on the flowchart of FIG.

A monitoring sensor (not shown) repeatedly checks for the occurrence of an abnormality in the monitored device, and turns on the monitoring input Ki when an abnormality occurs.

The alarm determination circuit (6) determines whether the alarm condition is satisfied based on the response signal and the monitoring input Ki, and outputs an output indicating that the alarm condition is satisfied when the monitoring input Ki is on and no response signal has been input yet. is sent to CPU (1). Upon receiving that output, C
PU (1) dials a predetermined reporting destination. CPU (1
) picks up the receiver at the designated reporting destination, and when it detects that the line has been closed, it sends an abnormality alarm command signal Pi to the voice generating circuit (4) and generates a voice signal that says, for example, "Device Noi has failed." to occur. If the person who received the report at the specified destination is, for example, a person responsible for monitoring, when the voice report has been received, the person who received the report at the specified destination, for example, presses a specified push button on the telephone to send a response signal to the super alarm device. Send it back. Alarm determination circuit (6) via response detection circuit (5)
When it receives the response signal, it cancels the establishment of the above-mentioned alarm condition. Therefore, the alarm operation is repeated only from when the CPU (1) monitoring input Ki is turned on until the alarm determination circuit (6) receives the response signal.

In this way, it is possible to reliably transmit and make the person responsible for monitoring the monitored device aware of the reported matters.

Therefore, unlike in the past, the report does not become meaningless because a person who cannot understand the information to be reported picks up the receiver.

FIGS. 4 and 5 are block diagrams and flowcharts according to another embodiment of the present invention.

This embodiment is different from the above-mentioned embodiments in that the alarm determination circuit (6
) is different, therefore, only the alarm determination circuit (6) of this embodiment is shown in FIG.

In the same figure, (00) represents each flip-flop (6a)
A switch connected to the reset terminal of ~(6n), (6
1) is an OR circuit that takes the logical sum (OR) of the outputs of each flip-flop (6a) to (6n), and (62) is an OR circuit (
61) is a lamp that is turned on and off by the output.

In other words, in the device of this embodiment, it is possible to notify a person close to the device that a report is being made to a predetermined destination by turning on the lamp (62), and also by turning on the switch (00) by that person. The reporting operation can be terminated.

If an abnormality in the monitored device can be recognized by someone close to the device and can be dealt with, there is no need to repeatedly report to a predetermined reporting destination, and the device of this embodiment is configured with such a case in mind.

In both of the embodiments described above, the response signal is a signal generated by pressing a push button on a telephone, but it may also be a sound signal in accordance with Morse code formed by a person at a predetermined destination, and in this case, This has the advantage that the present device can be applied to any type of telephone, without being limited to a push type telephone at a predetermined reporting destination.

〔Effect of the invention〕

As described above, according to the present invention, the reporting operation is repeated until a response signal is returned from a predetermined reporting destination, so that the person responsible for monitoring the monitored device can be assured of monitoring details such as abnormalities. can be reported, greatly improving security.
