Abstract

PURPOSE:To prevent a fault arising at a receiver in an emergency mode, etc. by driving a sound output device to inform the originating side that the dialing is wrong in case the originating side has the wrong dialing with a receiver exclusive for reception of data from a specific device. CONSTITUTION:A network controller NCU2 detects the presence or absence of an incoming call, then closes a telephone circuit if an incoming call is detected to wait for the prescribed data to be fed from a specific device like an informing device, etc. Then the NCU2 decides that the originating side is equal to a specific device when the prescribed data is received by a data receiver 1. A CPU4 has the prescribed processing based on the received data and sends the data to an output device 6. Then the device 6 delivers the processing data and opens the telephone circuit. While it is decided that the originating side is equal to a human being not a specific device in case it is impossible to receive the prescribed data within a fixed period of time after the telephone circuit is closed. Thus a sound output device 8 informs in voices via the telephone circuit L that the dialing is wrong.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a receiving device in a remote monitoring system. The output device notifies the user that the dialed destination is incorrect.

[Prior art]

2. Description of the Related Art A receiving device dedicated to data reception in a long distance monitoring system has conventionally been configured as shown in FIG. 1, for example.

In the above configuration, the data receiving device (
When a call occurs in 1), the R in the network control unit (2) (hereinafter referred to as NOU) that controls the closing and opening of the telephone line
Since the relay (8) turns on and off at regular intervals, contact r
The microprocessor (4) (CPU) detects the occurrence of an incoming call and turns on the 8 relay (5).

As a result, the contact point t of the telephone line is turned on, the telephone line is closed, and connection with the data receiving device &(1) is established, making it possible to receive data.

A capacitor C is inserted between the contact t and the R relay (8) to prevent them from forming a DC loop.

Therefore, if the source of the call to the receiving device is the reporting device, the dead body will be sent to the predetermined data reception 'Mf! (1,) within a certain time after it is closed. Then, the data 'lx 9 <8, the CPU (4'i) performs predetermined data processing, and the output device (6) outputs processed data corresponding to the data.

After receiving the data, the data receiving device (1) connects the telephone [
The J line will be opened. In addition, if the destination of the call opens the telephone line, the polarity of the telephone line is reversed, so a FIJ relay (7) is installed in the telephone line to detect the reverse polarity. When contact f is activated, the destination of the call releases '1' (assuming that the line has been opened, returns B relay (5), and returns IJ to '111').

However, if the destination is other than a radio alarm device that transmits predetermined data, that is, if a person mistakenly dials the receiving device, the data at W will be received within -1f41 hours after the line is closed. Data love device (1) because it is not sent
) is determined that the destination is other than the alarm device = y.11ji L
'Open the cheering bullet.

In such a case, the person on the other end of the call will be disconnected as soon as the phone line is connected (σ), so it will take time for the person on the other end of the call to realize his or her mistake, such as dialing the person again. On the IM equipment side, repeating erroneous notifications by humans monopolized the telephone line, preventing necessary data transmission from the notification equipment V during the delivery period, which could lead to problems in emergencies.

[Summary of the invention]

The present invention has been made in view of the points mentioned in "-", and when the destination of the call mistakenly dials a receiving device dedicated to receiving data from a specific device, the voice output device is activated and the destination is contacted by voice. The purpose of the present invention is to provide a complete receiving system for a remote monitoring system that notifies the user that a call is being made and that there is no problem with the receiving device in an emergency or the like.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG. 2, in which the same parts as in FIG. 1 are given the same reference numerals.

In the present invention, the microprocessor (4) has a means for distinguishing whether data sent from the diaphragm is predetermined or not, and a K11i-voice when it is determined by this discriminating means that the data is not the predetermined data. It has an output device W (W that sends drive commands to sr).

The voice output device M (8) is driven by a drive command from the microprocessor (4) and is used to notify by voice that the destination has been dialed incorrectly via the telephone line.

Next, according to the flowchart in FIG. 5, the operation V of the above configuration is
Let me explain about C.

Then, at (3-+), the presence or absence of an incoming call is detected by NCU (21), and when the presence of an incoming call is detected, the call is concluded at (3-2), and a message is sent from a specific device such as a reporting device. If the predetermined data of (;Ir"':l, (3-3) is received, it is determined that the destination is a phase-setting device, and then (5-4)
Receive and update data with the Data Love Device (]).

CP +J t4) performs predetermined processing based on the received data, then sends it to the output device 1ffi (6), and (3-5
) outputs the processed data from the output device (6). Then, at (3-6), the '11 talk line is released and the process ends.

Next, after the line is closed in (3-2), if the specified data cannot be received within a certain period of time in (ro-5), then (3-7)
), it is determined that the person ahead of call 1 is a person rather than a specific device, and
At (3-8), the voice output device (8) notifies the user via the telephone line that the dialed destination is incorrect. That is, (1) the other party to which Jikinuta was applied is a receiving device +i dedicated to receiving data from a specific device; (2)
(3) In the case of a call to the monitoring 7-unit, tell the dial number of the 7-phone line called by the one-stop machine that can send and receive by voice, and then repeat the same as above (5-6). ) to unlock the telephone number win.

The above-mentioned voice output device (8) is configured so that, for example, the above-mentioned information such as "Dial number is incorrect" is recorded in advance, and the information is outputted by drive commands from the microprocessor (4). Furthermore, the audio output is not limited to one output, but may be output nine times.

〔Effect of the invention〕

As described above, the present invention provides a data receiving device dedicated to receiving data from a specific device, a discrimination means for discriminating whether or not the data is a predetermined data from the specific device, and a microcontroller that detects when the discrimination means determines that the data is not the predetermined data. The voice output device g is driven by the drive finger from the processor, and it is possible to loudly notify the person on the calling side via the telephone line that there is a mistake in the dialing, so the user can receive the call repeatedly without noticing the mistake. This eliminates unnecessary trouble such as dialing a device, and on the receiving device side, data reception from a specific device is not hindered while a human continues to call the device again.Especially in an emergency, immediate data reception allows subsequent measures to be taken quickly. There are effects such as being able to perform.
