Description

[Detailed description of the invention] The present invention relates to an automatic notification device that automatically reports various disaster prevention information 4 such as theft, fire button, gas leak, etc. using a telephone terminal, and is particularly concerned with preventing false notifications 4 due to collision between incoming and outgoing calls. As it relates to an automatic reporting device that can
Upon input of the automatic report command signal, the telephone line is closed and the pre-destination is automatically dialed in 4 lines.After the call is answered, the report information is automatically sent through 4 telephone lines, and the incoming signal tone is detected and a telephone call is made. This invention relates to an automatic notification device that automatically sends out an incoming call response message 4 after all lines are closed.

This type of sensor output brass is a notification device that operates the entire auto dial circuit, dials all the preset numbers of the other party through the entire telephone circuit, and when the other party answers, sends a message to the other party using a tape recorder or digital signal transmitter inside the sensor. Even if an answering machine is equipped with an answering function that automatically answers an incoming call and sends an answering message, it generally monitors whether the incoming call detection relay (R relay) is operating and sends a notification based on sensor operation when an incoming call is received. It prevented operational noise.

However, in such devices, the incoming call signal is sent at a timing of 1 second and 2 second pause, so if you start calling from a pause, the RIJ relay in the incoming call detection circle cannot operate, and the sensor will not work. When it worked, it had the inconvenience of turning on the line relay (L relay) and turning on the entire auto-dial circuit without any incoming calls.

In view of the above points, this invention has been developed to solve such problems.The purpose is to prioritize all incoming calls and perform all reporting operations when outgoing calls overlap, thereby preventing erroneous notifications caused by collisions between incoming and outgoing calls. We provide an automatic reporting system that can

In order to achieve all of these objectives, the present invention includes a dial tone detection circuit that detects all dial tones arriving on a telephone line, and a system that sends notification information based on the output of the dial tone detection circuit when an automatic notification command signal is input. command signal l
It is equipped with a command signal generation circuit 4 for sending all command signals for sending out messages in response to incoming calls, and is designed to prevent false notifications 4 caused by collisions between incoming and outgoing calls.

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

The line relay Lk is built into this device.

SR,1t S R2...SRn is a sensor that dynamically detects situations that should be sent, such as theft, fire, gas leak, and a safe locked. The notification device is configured to be controlled by EAETh.

AD is an AC signal detection circuit that detects AC signals such as dial tone and busy tone from the telephone line, and JC is the output input of the AC signal detection circuit AD, and is a judgment circuit that determines whether or not there is a dial tone. A dial tone detection circuit is also configured to detect dial tone 4 arriving at the same time.

SMS is a sensor message sending command signal generation circuit that is activated by closing a contact (not shown) based on the operation of the called party response detection relay ADH, and AMS is a contact (not shown) based on the operation of the incoming call detection relay R. This is an answering message sending command signal generating circuit which is driven by the output of the dial tone "absent" from the closing or determining circuit JC. It constitutes a command signal generating circuit which sends a notification information sending command signal or an incoming call response message sending command signal based on the output of the dial tone detection circuit when an automatic notification command signal is input.

MS and answer message sending command signal generation circuit A
The tape recorder TRk is controlled by a command signal from the MS, and the sensor message and the answering message from the tape recorder TR are configured to be transmitted by switching channels 4.

Next, the operation sounds of the embodiment shown in this figure will be explained.

Since the operation other than the part enclosed by the dashed-dotted line is generally well known, a detailed explanation will be omitted. The output activates the incoming call detection relay R.

On the other hand, in the case of a call, terminal L1 - contact 4 - dial impulse contact Di - dial shunt contact D8 - terminal L
The two closed-loop gold dial impulse contacts Di provide a ringing signal to the called party through the four telephone lines.

When the called party responds, the called party response detection relay ADH operates by reversing the polarity of the voltages applied to the terminals Ll and L2, thereby detecting a lever response.

The automatic notification device according to the present invention can be implemented as follows.

1. Even if the relay R of the incoming call detection circle is not operating, it is turned on by the automatic notification command signal of the line relay Lk, and after the telephone line is completely closed by closing its contact L, the transformer T is turned on.
AC signals such as continuous dial tone and busy tone are detected by AC signal detection circuit AD.

Then, if there is a dial tone, the line is idle, and if there is no dial tone, it is determined by the determination circuit JC that the line is in response to an incoming call.

As a result of this judgment, if the line is empty, the output a of the judgment circuit JC indicates that there is a dial tone. If relay ADH operates,
The sensor message sending command signal generation circuit 5M5k is driven by the contact of the relay ADR, and all sensor message sending commands are sent out.
Select and send out all sensor message channels.

Here, this sensor message is a pre-recorded message, for example, "...ku...machi...chome...
Number... number... company.

This information is automatically sent to the called party via telephone line 4, stating that an emergency situation involving theft occurred some time ago.

On the other hand, the judgment circuit JC determines that there is no dial tone.
If it is determined that this is the case, after the relay R for incoming call detection operates, the contact of the relay R is closed or the output bK of "absence" of the judgment circuit JC drives the answer message sending command signal generation circuit AMSTh, and the answer message is sent. This command selects and sends the message to the answering machine message channel of the tape recorder TR.

Here, this answering message is a message that has been recorded in advance, for example, ``I'm away at the moment.''

'' information is automatically sent to the four called parties through four telephone lines.

In this way, when incoming and outgoing calls overlap, the incoming call is given priority and the reporting action is set, so there is no need to run the auto dial circuit fully while receiving a call, as was the case in the past, and the answering function is fully utilized. Disaster prevention information detected by the sensor can be automatically sent to the called party via the gold telephone line.

As is clear from the above explanation, according to the present invention, when there are duplicate call operations, the incoming call is prioritized and the reporting operation is performed to prevent false notifications due to call conflict. The effect is extremely large.
