Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic dialing announcement device.

An automatic dialing announcement device that sequentially reads telephone numbers from a recording medium that records a large number of subscriber telephone numbers, automatically dials them, and automatically sends a required message when the called party answers. For example, it has already been put to practical use in the telephone office's telegraph telephone billing business. As such an automatic dial announcement device, for example, Japanese Patent Application Laid-open No. 138804/1983 discloses a device that automatically reads the telephone numbers of a large number of subscribers who are to send a predetermined message recorded on a perforated tape one after another using a tape reader. When the called party answers, a prerecorded message is automatically sent, and if the called party is busy or does not answer, the phone number is sent to the tape punch device. There is described a system in which the telephone numbers of all subscribers who have not responded after being called are recorded on another tape of the same type, and the tape is loaded onto a tape reader to perform a re-call. However, in this automatic dial announcement device, when the called party does not answer, the telephone number is recorded on a separate tape using a tape punch device, which has the disadvantage of making the entire device large. This system has the drawback that the operation is troublesome because the operator manually records the telephone number of the unanswered subscriber after the subscriber is called, and then uses the tape reader to call again.
Furthermore, since only the telephone number of the subscriber is recorded on the tape, it is necessary to create a tape according to the message to be sent, and therefore there is a drawback that it lacks versatility.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks, to provide an automatic dial announcement device that can be made compact as a whole and has excellent operability and versatility.

The present invention includes a storage means having a large number of subscriber data columns storing information and telephone numbers related to each subscriber, and a storage means for identifying subscribers meeting preset conditions from the subscriber data stored in the storage means. automatic dialing means that sequentially selects and automatically dials telephone numbers; automatic announcement means that transmits a message that meets the preset conditions in response to a response from a called party dialed by the automatic dialing means; a detection means for detecting a call state of the called party, such as a response, a busy call, or a non-response due to no answer; and information representing the call state detected by the detection means is recorded in a corresponding subscriber data column of the storage means. and a control means for controlling the automatic dialing means to make a re-call in response to a non-response in accordance with the information representing the call status recorded by the recording means.

The present invention will be described in detail below with reference to the drawings.
FIG. 1 is a diagram showing the configuration of an example of an automatic dial announcement device of the present invention. This automatic dial announcement device selectively connects the subscriber's telephone 1 to the subscriber telephone line on the subscriber side, and employs a selection signal system depending on the telephone 1. In this example, it is assumed that the telephone set 1 employs a dial pulse system, and therefore the automatic dial announcement device is configured to call a desired subscriber by dial pulses. The subscriber telephone line to which the telephone set 1 is connected is connected through relay contacts 2-1 and 2-2 which are activated by the telephone switching relay 2 and relay contacts 3-1 and 3-2 which are activated by the driving of the hooking relay 3. and connect it to the primary side of transformer 4. In this example, relay contacts 2-1 and 2-2 are connected to the telephone 1 when the telephone switching relay 2 is deenergized.

A relay contact 6-1, which is activated by driving the dial-in bus relay 6, is connected in series between the dial-in bus relay 6 and the relay contact 3-1. Further, a series circuit of a resistor 7 and a capacitor 8 is connected in parallel to the relay contact 6-1. In this example, dial shunt relay 5
When the relay contact 5-1 is energized, the relay contact 5-1 is closed, and when the relay contact 5-1 is closed, the dial impulse relay 6 is driven according to the required telephone number, thereby opening and closing the relay contact. Generates a dial pulse according to the telephone number.
Furthermore, between the relay contacts 3-1, 3-2, the transformer 4, and the primary side, there are connections for detecting the response of the called party.

7 (personal computer). The drive of each relay 2, 3, 5, 6, 10 and audio cassette device 13 is controlled by a computer 17 via an interface 16 and corresponding inverters 15c to 15i. Furthermore, the computer 17 is connected with a keyboard 18, a floppy disk device (FDD) 19, and a display device 20 consisting of a CRT. Note that the above inverters 15a to 15i can also be incorporated into the interface 16.

FIG. 2 shows a circuit configuration diagram of an example of the AB lever detection circuit 9. As shown in FIG. In this example, a photocoupler 21 is used, and when the called party answers, the -
The photodiode 21a is connected to the subscriber telephone line through a resistor 22 so that the photodiode 21a emits light when the 48V voltage is reversed. In addition, the collector of the phototransistor 21b of the photocoupler 21
The emitter path is connected to the power supply voltage V _cc via a resistor 23.
At the same time, a capacitor 24 is connected in parallel between the collector and emitter, and its terminal voltage is applied to the inverter 15a. In this way, when the called party answers, an H level signal is obtained from the inverter 15a, and when the called party does not respond, an L level signal is obtained.

FIG. 3 shows the configuration of an example of a control circuit for the telephone switching relay 2. As shown in FIG. In this example, a transistor 25 is used, which is fixedly biased by a resistor 26, and a telephone switching relay 2 and a reverse current blocking diode 27 are connected to its collector-emitter path in parallel, and a power supply voltage _Vcc is applied. ,
The output of the inverter 15c is supplied to the base terminal of the transistor 25 via the resistor 28. In this way, when the output of the inverter 15c is set to H level, the transistor 25 is made conductive to energize the telephone switching relay 2, thereby connecting the subscriber telephone line to the automatic dial announcement device, and the output of the inverter 15c When is at L level, the transistor 25 is made non-conductive, the relay 2 is turned off, and the subscriber telephone line is connected to the telephone set 1 side.

The control circuits of the other hooking relays 3, dial shunt relays 5, dial impulse relays 6, and announcement switching relays 10 are also constructed in the same manner as shown in FIG.

FIG. 4 shows an example of the file format of a floppy disk to be installed in the floppy disk device 19. In this example, we set up a number of subscriber data fields with areas to record the record number (RN), telephone number, relevant information related to the subscriber, and call status;
Record the RN, phone number, and related information in advance. As various conditions of the subscriber, for example, the number of family members, occupation (coded), number of cars, televisions, refrigerators, vacuum cleaners, electric kettles, and automobiles are recorded. To record the RN, telephone number, and related information in each subscriber data field, for example, use the automatic dial announcement device shown in FIG. By computer 17
This can be done while being displayed on the display device 20 via.

The operation of this embodiment will be explained below with reference to the flowchart shown in FIG.

First, as shown in FIG. 4, when a floppy disk on which the telephone numbers and related information of many subscribers are recorded in advance is attached to the floppy disk device 19, the call status writing area of all the subscriber data columns is At the same time, clear the conditions of the subscriber's related information to be read according to the message to be sent via the keyboard 18, the number of transmissions, and the start RN.
These conditions are set through conversation with the display device 20. When the condition setting is completed, the telephone switching relay 2 is energized (ON), the automatic dial announcement device is connected to the subscriber telephone line via the relay contacts 2-1 and 2-2, and automatic dial announcement is started.

In the first transmission, the subscriber data from the set start RN to the last RN is read out sequentially, but when reading out the subscriber data sequentially, an interrupt signal for forced termination is first sent from the keyboard 18. If there is no interrupt, it reads out the data for one subscriber and determines whether it meets the setting conditions. If there is an interrupt, it turns off the telephone switching relay 2. ) and connects the subscriber telephone line to telephone set 1 via relay contacts 2-1 and 2-2, thereby forcibly terminating the automatic dial announcement. If the read one subscriber data matches the setting conditions, the data shown in FIG. 6A
As shown in the figure, the hooking relay 3 is turned on, and it is detected whether or not there is a DT within 5 seconds from that point to determine whether or not the line has been seized.
On the other hand, if the read subscriber data does not match the setting conditions, the read subscriber data
Determine whether RN(n) is the last RN, and
If it is not RN, 1 is added to the read RN(n) to similarly determine whether or not forced termination is to be performed, the next subscriber data is read, and it is determined whether or not the setting conditions are met.

Turn on footing relay 3 and turn it on within 5 seconds.
When DT is detected, dial shunt relay 5 is activated as shown in FIG. 6B at the time of detection.
is turned ON, and the dial impulse relay 6 is driven to send out a dial impulse as shown in FIG. Turn off. On the other hand, if DT is not detected within 5 seconds from the time when the hooking relay 3 is turned ON, the hooking relay 3 is turned OFF after 5 seconds have elapsed, the number of times R of flexing is counted, and the counted value R is It is determined whether the preset value (3 in this example) is met, and if R<3, the hooking relay 3 is turned on again to detect DT, and if R=3, it is considered to be a line failure. Then, turn off the telephone switching relay 2 and forcibly terminate the automatic dial announcement. In addition, the count value R
is cleared when DT is detected.

After the transmission of the telephone number is completed and the dial shunt relay 5 is turned off, within 20 seconds from that point
It is determined whether or not BT, AB Reverse, and RBT are detected. If BT is detected, it is determined that the call is busy at the time of detection, and if AB Reverse is detected, it is determined that there is a response at the time of detection. Also, when an RBT is detected, an additional 20
It is determined whether the RBT disappears within seconds or whether there is an AB reversal, and if either of these is detected, it is determined to be a response at that point, and if neither is detected, it is determined that there is no response after 20 seconds have elapsed. judge. Furthermore, within 20 seconds after turning dial shunt relay 5 OFF, BT, AB lever and
If none of the RBTs are detected, it is assumed that the line is congested, and in this case as well, it is determined that there is no output.

When it is determined that there is a response, at that point, Figure 6D
As shown in the figure, the announcement switching relay 10 is turned on and its relay contacts 10-1 and 10-2 are connected to the audio amplifier 14 side, and the audio cassette device 13 is started to send out a message according to the set conditions. The announcement switching relay 10 is turned OFF in synchronization with the completion of transmission of the message. Note that this audio cassette device 13 is
When activated, playback starts from the beginning position of the tape, and after a predetermined announcement, the tape automatically starts playing.
It is controlled to be rewound and set to the starting position. When the transmission of the required message is completed in this way, information representing the response is written in the call status writing area of the read subscriber data column, the hooking relay 3 is turned off, and the RN of the subscriber data is Determine whether or not is the last RN and move on to the next process. On the other hand, when it is determined that the RN is busy or not answered, the first non-response RN of the busy or non-answered state is stored in the memory in the computer 17, and the number N of non-responses is counted and read out. Write information indicating busy or not available in the call status writing area of the subscriber data field, and then activate the hooking relay 3 in the same way as described above.
At the same time as turning it off, it is determined whether the RN of the subscriber data is the last RN.

The predetermined processing described above is performed on the read subscriber data, and in the block that determines whether it is the last RN, the read subscriber data is
When the RN is determined to be the last RN, the number of transmissions M is counted and it is determined whether the count value is the preset number of transmissions. Here, if the number of transmissions M matches the set number, for example, the set number is 1.
When the predetermined processing for the subscriber data from the preset start RN to the last RN is completed, the telephone switching relay 2 is turned off to end the automatic dial announcement. In addition, when the number of transmissions M does not reach the set number, for example, if the number of settings is multiple and the number of transmissions M is 1, that is, the preset start
If only one transmission from the RN to the last RN has been completed, it is then determined whether the number of non-responses N counted in that one transmission is zero.
Here, when the number of non-responses N is zero, that is, when all subscribers meeting the setting conditions have responded, no further transmission is performed, and the telephone switching relay 2 is turned off to terminate the automatic dial announcement. In addition, if the number of non-responses N is not zero, that is, if there is a subscriber who does not respond due to being busy or not answering among the subscribers who meet the setting conditions, the first non-response stored in the previous transmission will be Read RN,
Specify this as the start RN for the next transmission, and from this specified start RN to the last
The subscriber data up to RN is sequentially read out, the subscriber to whom retransmission is to be selected is selected, and an automatic dial announcement is made in the same manner as described above. In this case, the subscriber to whom the retransmission should be made is determined whether the read subscriber data matches the setting conditions or not. It determines whether or not it is non-response information and selects it, and retransmits only to subscribers who meet the setting conditions and for which non-response information is recorded. In addition, in this retransmission, in synchronization with the reading of the specified start RN, the contents of the memory that stores the previous first non-response RN are cleared, and the first non-response RN in this transmission is cleared.
In addition to storing the RN, the count value N of the number of non-responses from the previous time is cleared to count the number N of non-responses in this transmission.

FIG. 7 shows an example of information recorded in the call status writing area of the subscriber data column.
This example shows the case where subscribers with two or more family members are selected from the file shown in Figure 4 and an automatic dial announcement is made. ANS indicates when the subscriber responds, and NOA indicates when the subscriber does not respond. , BSY represents the case where the subscriber is busy, and a blank field represents the case where the subscriber was not selected because the subscriber did not meet the setting conditions. If there is a next transmission here,
Retransmission is performed only to NOA or BSY subscribers who are in a family of two or more, and the information in the call status writing area is rewritten according to the call status at that retransmission to prepare for the next retransmission.

According to the embodiment described above, the subscriber's telephone number is not recorded on another floppy disk, but the subscriber's telephone number is read out on the same floppy disk. Since the telephone call status of the subscriber who answered and the unanswered call is recorded, and the unanswered subscriber is automatically called again according to the call status, only one floppy disk device 19 is required. Therefore, the entire device can be made compact, and the operation is extremely simple since there is no need for the operator to replace the storage medium, which is required when recording the telephone number of a non-responsive subscriber on another storage medium. . In addition to the telephone number, information related to the subscriber is also recorded in the subscriber data field, and by specifying conditions for the related information, subscribers who meet the conditions can be selected and responded to the specified conditions. By preparing one or separate cassette tapes on which different messages are recorded, for example, it can be used to promote products in department stores, shops, etc., to communicate events, and in organizations such as companies, schools, kindergartens, etc. It is possible to select a subscriber who satisfies the required conditions from among a large number of subscribers recorded on one floppy disk for telephone forwarding, etc., and is therefore highly versatile.

Note that the present invention is not limited to the above-mentioned example, and can be modified or changed in many ways.

For example, in the above-described embodiment, the telephone 1 employs a dial pulse system, but even if the telephone 1 employs a multi-frequency signal system, the same implementation can be performed by changing the dialing configuration accordingly. can. Further, in the above example, a floppy disk was used as the storage medium, but other storage media such as a magnetic tape or a magnetic drum may also be used. Further, by using a plurality of telephone lines, an automatic dialing device and an audio cassette device are connected to each of these telephone lines, and required subscribers sequentially read from one storage medium are distributed to these plurality of telephone lines, In other words, it is also possible to perform an automatic dial announcement by allocating required subscribers read out sequentially to a telephone line for which the required operation for one subscriber has been completed. Also,
The condition for the subscriber to be called is not limited to a single condition, but can also be set to a plurality of conditions (for example, in FIG. 4, a family of three or more people and two or more cars). Furthermore, in the above example, the case where no signal is detected within 20 seconds after dialing due to line congestion and the case where no response is detected within 20 seconds after RBT detection are treated as the same "non-delivery". However, it is also possible to distinguish these into, for example, "unreachable" and "absent" and record them in the call status writing area of the subscriber data column. Furthermore, clearing the call status writing area of the subscriber data column prior to the first dialing does not necessarily need to be performed for all subscribers, but may be performed only for the subscriber to be called. Note that if this clearing is performed for all subscribers as in the above-described embodiment, it is also possible to determine only the information in that area and perform retransmission. Furthermore, in the above example, retransmissions for non-responsive subscribers are
This was done in order, but by ranking the contents of non-responses, for example, re-transmitting to the subscriber who was busy first, and then re-transmitting to the subscriber who did not respond. You can also. Furthermore, as the audio cassette of the audio cassette device 13, for example, a compact cassette, a micro cassette, an endless tape, etc. can be used.

As described above, according to the present invention, retransmission to a non-responsive subscriber is automatically performed using the same storage medium without recording the telephone number of the non-responsive subscriber in a separate storage medium. By doing this, the configuration of the device can be simplified, the entire device can be made smaller, and the operation can be made easier. In addition, in addition to the subscriber's phone number, the storage medium is also pre-stored with information related to the subscriber.
By preparing a message according to the conditions to be called, it is possible to automatically dial and announce the required message to subscribers according to various conditions using one storage medium, and it is therefore highly versatile.
