Description

Description: TECHNICAL FIELD The present invention relates to an order entry method, and in particular, to a communication system using an inexpensive voice signal from a PB signal transmission terminal that can be introduced to ordinary households. The present invention relates to an order entry method for performing an order entry service by using a method.

[Related Art] In recent years, order entry in which an order for a product is made from a general household has become common.

As a conventional technique relating to a method of electrically and mechanically performing such order entry from a general household, a PB signal communication method using a push-button telephone and a voice response device, a personal computer communication method using a personal computer, or ,
A technique using a barcode input method using a barcode reader is known.

Each of these techniques has the following problems.

That is, in the case of using the PB signal communication method, it is necessary to press the push button by hand in a timely manner, and the operation is complicated. In addition, the conventional technology using a personal computer, a bar code reader, etc., is too expensive for these terminals to spread to general households. There is a fear that they will not be given.

As another conventional technique, an order entry method using OCR, which is supported by recent improvements in character recognition technology, is known. This prior art requires an off-line 4 input and an OCR sheet collection process, which is unsuitable for urgent orders that require a long turnaround time from order placement to product delivery.

Therefore, as an inexpensive and compact order-only terminal that can be ordered in real time (short turnaround time) with good operability, which can be accepted in ordinary households, an order terminal using the PB signal system is accepted again. It is being done. Behind this is the type of microphone on the phone,
A carbon microphone, which has been a major cause of PB signal degradation, has been changed to a condenser microphone, and it is not overlooked that the use of this condenser microphone has improved the PB signal transmission quality.

By the way, in order entry using the conventional PB signal system, cancellation of order contents, quantity change, and additional order have been performed as described below.

That is, this prior art is sent from an order terminal.
The PB signal gives the order data information on whether the order is to place an order for a product or the order to cancel the order, and such order data is transmitted to a PB signal receiving device such as a voice response device. In the receiving apparatus, an order or cancellation is determined, and the order and cancellation are performed based on the result.

In the prior art using the PB signal method, as described above, in order to cancel the content once ordered, it is necessary to simultaneously input the cancellation content to the order terminal and send it to the receiving device, and once In order to change the quantity of ordered products, it is necessary to cancel the order data described above and then re-order the required number of products. This requires a procedure of inputting order data again to the order terminal and placing an order.

As a conventional technique related to the order entry as described above, for example, the technique described in Hitachi Review, Vol. 63, No. 12, “Input / Output Device for Voice Response System” is known.

[Problem to be Solved by the Invention] In the conventional technique, when canceling the ordered contents and changing the quantity, it is necessary to newly confirm the canceled product quantity, the changed product, and input to the order terminal. In the case of reducing the quantity, it is necessary to perform two PB signal transmission operations of cancellation and reordering, and the operation for that becomes very complicated.

Further, according to the conventional technique, while repeatedly canceling and re-ordering, the orderer loses the understanding of the final state of the order content, and a situation occurs in which the order center must be inquired. Has problems.

It is an object of the present invention to provide an order entry method capable of solving the above-mentioned problems of the prior art and providing a user-friendly order entry service with good operability.

[Means for Solving the Problems] According to the present invention, the object is to input the required quantity of the ordered goods into the data to be transmitted for performing the order entry, and In the case of an additional order, this is achieved by inputting the required absolute number, including the number of orders, instead of inputting the relative number from the number of orders. The processing is also achieved on the host computer side where the latest information (quantity) is processed as valid information for the same product ordered.

That is, according to the present invention, when canceling an order and reordering by changing the quantity,
This is achieved by making corrections and additions, and simultaneously inputting the unchanged order details and retransmitting. At this time, the information remaining in the order terminal is the final state ordered by the user.

[Operation] The contents of an order input from the order terminal to order a product include a user ID code, a catalog code of a catalog in which the product to be ordered is described, a product code, a quantity, and the like.

In the case of canceling or changing the order once the order has been placed, this is done by inputting the absolute number required for the reorder quantity, for example, zero in the case of canceling. The above-mentioned order contents are changed by once reading out the previous order contents and correcting and adding the data. The changed order data is transmitted to a PB signal receiving device such as a voice response device on the receiving side, together with data relating to the unchanged product.

The host computer that processes the order content on the receiving side, during the period when the catalog code is valid, the latest information sent from the PB signal receiving device such as the voice response device for the order content from the same user, The import processing is performed as the contents of the order from the corresponding user.

Next, a description will be given of a processing operation when ordering a product or the like according to the embodiment of the present invention configured as described above.

FIG. 7 is a diagram showing a sequence of the order processing, and the operation of the order processing will be described below with reference to this figure.

(1) The user of the order entry system according to the present invention uses his / her keyboard 13 to input his / her ID code into the order terminal 1 and, at the same time, view the catalog of the already distributed products, Enter the product code and quantity of the product you want (data input).

In this input process, the input numbers are displayed on the display 12, so that the user can work while confirming the input. Further, the input various data is stored and held in the backup battery RAM 19, and the contents are held even when the main power supply of the order terminal 1 is turned off.

In this data input, an input error or the like can be considered, so that it is possible to correct the once input data, add the number of ordered products, and the like.

(2) When the above input is completed, the user makes a call to the voice response device 4 by the telephone 2 (call).

(3) On the other hand, the voice response apparatus 4 which has detected the incoming call signal from the public network 3 by the communication control unit 41 performs an incoming call operation (answered call) using the communication control unit 41, and Form a path (incoming call).

(4) At this time, the voice response apparatus 4 normally asks the calling party, that is, the user, to confirm the incoming call.
is. Please send. Is returned. For this purpose, the CPU 44, which has received the call report from the communication control unit 41, outputs a digital voice file (for example, a 64 Kbps μ-lawP) stored in the disk 47.
It can be obtained by retrieving the CM voice) and converting it into an analog signal by the D / A converter 43, and transmitted to the telephone 2 via the communication control unit 41 and the public network 3.

(5) If the incoming call to the voice response device 4 can be confirmed as described above, the user places the mouthpiece of the telephone 2 at the position of the speaker 11 of the order terminal 1 and stores it in the backup battery RAM 19 by the keyboard 13. The PB signal is converted by the PB signal oscillating device 20 into the PB signal, a trigger for transmitting the PB signal to the speaker 11 is given, and the order data is transmitted (transmission).

(6) On the other hand, the voice response device 4 receives and analyzes the voice signal based on the PB signal transmitted from the order terminal 1 using the PB receiver 42, converts the voice signal into a digital value, and stores the digital value in the memory 45. When receiving the voice signal, the voice response device uses the order terminal 1 to improve the reliability of the acoustic communication system using the PB signal.
The check digit for error detection assigned on the order terminal 1 side by the error detection method such as a checksum for the transmitted data, which is predetermined between the telephone and the voice response device 4, is also checked on the voice response device 4 side. , Order terminal 1
The reliability of the received data is improved.

FIG. 3 is a diagram showing a format of data transmitted from the order terminal 1.

As shown in FIG. 3, this data includes an order message code for distinguishing from a cancel message and an orderer identification ID.
A code, a catalog code, an order number 2, which is a serial number of a product automatically added to the order terminal 1 sequentially for each product to be ordered, a product code, its quantity, and the end of data transmitted from the order terminal. And a delimiter code (for example, #).

The voice response device 4 determines the end of the received data by receiving the above-described delimiter code.

If there is an error in the received data due to the check digit error, the voice response unit 4 transmits a voice file requesting retransmission, for example, a voice file such as "Reception error has occurred. Please transmit again." After reading from the disk 47 and performing analog conversion by the D / A converter 43, the data is output to the telephone 2 via the communication control unit 41.

When the user transmits the order data by placing the mouthpiece of the telephone 2 on the speaker 11 of the order terminal 1, when the data transmission from the order terminal 1 is completed, the completion is, for example, performed by a buzzer. Since the user is notified by a ringing sound or the like, the user touches the receiver to his / her ear to hear the answer voice output from the voice response device 4.

(7) As described above, the voice response device 4 notifies the host computer 5 of the order data received from the order terminal 1 via the computer interface device 46 (order).

(8) The host computer 5 receives the order data from the voice response device via the computer interface device 51, and stores the order product code notified and the product master file corresponding to the catalog code stored in the disk 54. A collation check is performed, and a collation check is performed with the number of stocks of each product corresponding to the catalog code stored in the disk 54, and the order file corresponding to each ID code is stored on the disk.
Create within 54.

This order file is added and updated every time there is an additional order until the catalog card is valid, that is, immediately before order processing is performed based on the order file. When such an order file is created, an order reception number is assigned to each order so that the order file can be specified for each ID code. That is, the order file is created using the ID code and the order reception number as keys.

(9) The host computer 5 further responds to the voice response device 4 with a voice file number for a response in order to reply to the user whether or not there is a product that cannot be ordered due to a product master check error, lack of stock, or the like. Is notified of the non-orderable reception number and the order reception number (answer).

(10) The voice response device 4 is a computer interface
The voice of the voice file number for reply, the order non-order number and the order reception number received from the host computer 5 via the disk 46 are read from the disk 47, and the respective voices are combined, for example, "order number (No. 2)" Is not in the catalog. The order receipt number is (1234). Please confirm. ", The D / A converter 43, the communication control unit 41
Is notified to the user's telephone 2 via (voice response).

In this case, the reply voice file number in the voice response device 4 needs to be stored in the host computer 5 in advance. As the voice for reply, a total amount of the ordered item, a request for retransmission, a voice of thanks, and the like can be prepared and used in any combination.

(11) By the above processing, processing of one order is completed,
The on-hook of the voice response device 4 and the telephone 2 is performed, the public network 3 is released, and all the processing ends (on-hook).

 Next, a processing operation in the case of order cancellation will be described.

FIG. 4 is a diagram showing a data format used in the case of order cancellation.

The orderer who cancels the order inputs data using the order terminal 1 in accordance with the data format shown in FIG.

That is, when canceling an order, the user
After inputting an ID code, a catalog code, an order reception number output from the voice response device 4 when the order is completed, and a product code to be canceled, the telephone 2 calls the voice response device 4 and connects them. In this state, the mouthpiece of the telephone 2 is pushed onto the speaker 11 of the order terminal 1 to transmit the cancel data entered earlier from the order terminal 1, and the keyboard 13 triggers to send the cancel data. give. With this trigger, a cancellation message code is automatically added to the input data for cancellation, and the cancellation data is converted into a PB signal by the PB oscillator 20 and the
Output from 11.

Thereafter, the cancellation data is received by the host computer 5 as in the case of the order described above. The host computer 5 reads the order file stored in the disk 54 into the memory 53 using the ID code and the order reception number in the received cancellation data as keys, and reads the cancellation data content cancellation product code from the disk 54. It is deleted from the order file or rewritten to invalid data, and stored again in the disk 54 with the ID code and the order reception number as keys.

In the case of increasing or decreasing the quantity of ordered products, once the above-described cancellation operation is performed, a new order operation may be performed. It is only necessary to perform the order operation to which the order reception number is assigned. In this case, the host computer 5
Since there is a new order that overlaps with the previous order reception number, the previous order is invalidated and the new order is stored in a file.

Next, a description will be given of an embodiment of an order entry in which order contents can be canceled, a quantity changed, and an additional order can be performed by the same procedure.

FIG. 5 is a diagram for explaining an operation procedure of the order terminal when canceling an order, changing a quantity, and performing an additional order after once placing an order. FIG. 6 is a diagram illustrating cancellation of an order, changing a quantity, and an additional order. 9 is a flowchart illustrating an outline of a message receiving process on the host computer side when performing the process.

The cancellation procedure shown in FIG. 5 (a) is an example in the case of canceling the product code 123 once ordered.

First, the previously transmitted order data stored in the order terminal 1 is displayed on the display by using a function key such as a line feed. Next, for example, when the correction key is pressed, the product code 123 blinks to urge the correction of the product code.
When the input key is pressed in this state, the product code 123 is reset in the memory as it is, and the quantity 06 blinks to prompt the correction of the quantity. Here, when the quantity is corrected to 00 and the input key is pressed, the quantity 00 is registered in the memory, and the quantity of the commodity code 123 is registered as 00.

After the memory in the order terminal has been rewritten in this way, the telephone is used to call the voice response device, and the communication using the voice signal using the PB signal is performed, as in the case of a normal order. The order contents are entered into the host computer via the response device. In this case, the order contents of the product having the order number other than the order number 05 stored in the order terminal 1 are also transmitted to the voice response device 4 at the same time.

Next, the signal operation on the host computer side in this case will be described with reference to the flow shown in FIG. 6. (1) First, it is determined whether or not the received message is an order message, and the received message is other than the order message. If not, another message processing (not shown) is performed (step 600).

(2) If the determination in step 600 is an order message, the order file of the corresponding ID code is read from the disk 54 to the memory 53 using the ID code in the order message as a key, and the product code in the order message is It is determined whether or not it exists in the file. If it does not exist in the order file, it is determined that a new product has been ordered, and the product code and the order quantity are added to the order file as one record (step 620). , 630).

(3) If the product code in the order message already exists in the order file in the determination in step 620, the quantity of the corresponding product code in the order file is changed to the value of the corresponding product code set in the order message. Replace with quantity (Step 64
0).

(4) It is determined whether or not the product code in the order message to be searched is the final data. If the product code is not the final data, the process for the next product code is returned to step 620 and the process of executing the process is repeated. If it is the last data, the process of writing the order file from the memory 53 to the disk 54 is completed (steps 650 and 660).

In the quantity changing procedure shown in FIG. 5 (b), the same procedure as in the above-described canceling procedure may be executed, and the quantity data of the ordered product is changed so as to be the absolute quantity desired by the user. Can be changed. In this case, as in the case of the above-described cancellation procedure, the order terminal 1
After registering the changed product code and quantity in the RAM of
The telephone 2 is used to call the voice response device 4 to perform voice signal communication using a PB signal, and the order contents are entered into the host computer 5 via the voice response device 4.

Also in this case, naturally, the order contents of the product having the order number other than the order number 05 stored in the order terminal 1 are simultaneously transmitted to the voice response device, and the host computer 5
The same processing shown in FIG. 6 as in the case of cancellation is executed.

In the additional order procedure shown in FIG. 5 (c), after searching for the last record of the previously ordered contents using a function key such as a line feed, the next record is advanced to the position of the next order number using the line feed key. . In this example, it is assumed that the order number 05 is the last record ordered first, and the position of the new order number 06 is displayed on the display by line feed. At this time, the product code is displayed by a hyphen (-), meaning that the product code to be ordered has not been input.

Here, press a new product code, for example, 456, and enter key, register this product code 456 in RAM19, then press 08, and press the enter key.
Register 08 in RAM19.

In this case, as in the case of the cancellation procedure described above,
After registering the product code and the quantity added to the order terminal in the RAM 19, the telephone 2 is used to call the voice response device 4,
Performs voice signal communication using a PB signal, and sends the order number 01 to the order number to the host computer 5 via the voice response device 4.
Enter the order details together with the contents of 05. In this case as well, the processing shown in FIG. 6 is executed on the host computer 5 side in the same manner as in the case of order cancellation.

According to the above-described embodiment of the present invention, once an order has been placed, the order terminal can be operated when canceling the order, changing the quantity, or placing an additional order in the same procedure as when placing the order. Thus, it is possible to provide a user-friendly order entry service. Further, according to the above-described embodiment, the processing on the host computer side also includes:
The same program can be used to process all new orders, cancellations, quantity changes and reorders,
The effect that the number of development steps in software development on the host computer side can be reduced can be obtained.

Further, according to the above-described embodiment of the present invention, since the order content stored in the order terminal always indicates the latest order content, it can be used for confirming when the product has been delivered. The absolute number of the order contents can be grasped only by looking at the storage contents of the order terminal.

The configuration example and operation of the order entry system using the audio signal communication using the PB signal have been described above. Next, another embodiment of the present invention that uses a modification example of the audio signal communication using the PB signal will be described. .

This other embodiment of the present invention uses a PB originating from an order terminal.
A start code is added to the head of data by a signal.

FIG. 8 is a diagram showing a format of data by a PB signal when a start code is added, and FIG. 10 is a diagram for explaining an operation of the voice response apparatus 4 when receiving data by a PB signal to which a start code is added. This is a schematic flowchart, which will be described below.

In the format shown in FIG. 8, the start code is automatically given by the order terminal 1.
Further, in FIG. 8, the order message code and the catalog code shown in FIGS. 3 and 4 are not provided, but these codes may be provided.

(1) When order data having a data format as shown in FIG. 8 is sent from the order terminal 1 to the voice response device 4 as described above, first, the received data is converted to a start code (for example, *). ) Is determined, and the received data is read without buffering the received data until the start code is received. If the received data is the start code, Buffering is performed (steps 1000 and 1020).

(2) Next, whether or not the data is completed is determined by monitoring the reception of the delimiter code, and the delimiter code (for example, #)
Until the buffer receives the start code, buffer the received data after receiving the start code (steps 1040 and 1060).

(3) If it is determined in step 1040 that the received data is a delimiter code, the delimiter code is buffered and the reception is terminated (step 1080).

In the flowchart of the outline shown in FIG. 10, when the start code and the delimiter code cannot be received, the process is in an infinite loop. Therefore, in another embodiment of the present invention, the time monitoring from the start of reception to the end of reception is performed. Or
It is possible to determine the maximum allowable number of digits for buffering, and to terminate the reception processing as a reception error if the number of digits exceeds the time and the number of digits exceeds.

Next, a description will be given of a method capable of avoiding a reception error due to an inability to receive a control code such as a start code and a delimiter code (even when these control codes are unreceivable, a case where the data body is normal is relieved). I do.

FIG. 9 is a diagram showing a data format used in this case, and FIG. 11 is a schematic flowchart for explaining the operation of the voice response apparatus 4 in this case.

In this example, n consecutive start codes and n consecutive delimiter codes are assigned, and the order terminal 1 to which these are assigned is transmitted to the voice response device 4 in addition. In this case, on the voice response device side, if even one of a plurality of consecutive start codes and delimiter codes can be received, processing is performed such that the start code and the delimiter code are considered to have been received, respectively.

(1) It is determined whether or not the received data is a start code, and the received data is not buffered until the start code is received. When the start code is successfully received, the received data, that is, the start code is buffered. (Steps 1100, 1110).

(2) Next, the received data is read and discarded until the next received data is no longer a start code, and when the received data is no longer a start code, buffering of the received data is performed (steps 1120 and 1130).

(3) Thereafter, as in the case of the processing described with reference to FIG. 10, buffering of the received data is performed until the delimiter code is received once, and when the delimiter code is received, the delimiter code is buffered. The receiving process ends (steps 1140 to 1160).

FIG. 12 is a sequence diagram when a PB signal code is transmitted from the order terminal 1 to the voice response device 4 without adding a start code, and FIG. 13 is a PB signal code transmitted with a start code added. FIG. 7 is a sequence diagram in the case.

In FIGS. 12 and 13, the PB from the order terminal 1 is now displayed.
It is assumed that a button or the like of the telephone 2 is erroneously pressed before data transmission by a signal code, and the signal is received by the voice response apparatus 4 side.

In this case, in the example of FIG. 12 having no start signal,
Since the data received by the voice response device 4 is different from the data originally sent from the order terminal 1 due to the above-mentioned erroneously pressed signal, the voice response device 4 checks the check digit. Will cause a receiving error.

However, when there is a start code as shown in FIG. 13, since the range of the data by the PB signal transmitted from the order terminal 1 becomes clear, it is erroneously pressed before the data is transmitted at the order terminal 1. It is possible to prevent reception of unauthorized data on the voice response device 4 side by the PB signal push button,
It is possible to prevent a reception data error due to a lack of a start code and a delimiter code, and to improve the reliability of data transmission of a voice signal communication system using a PB signal.

Next, a method that can further improve the reliability of data transmission, that is, the order data by the PB signal transmitted from the order terminal 1 is divided into record units, and a check digit for error detection is divided for each record. A method of transmitting the data to the voice response device will be described.

FIG. 14 is a diagram showing a format of data by a PB signal to which an error detection check digit is added for each record,
FIG. 15 is a flowchart for explaining the reception analysis operation on the voice response device side in this case. The flow shown in FIG. 15 is a flow of a program started after storing the reception data in the memory 45 by the flow of the reception processing program shown in FIGS. 10 and 11.

(1) First, an ID code is extracted from the order data received from the order terminal from the memory 45, a check digit of the ID code is calculated, and the ID code is compared with the added check digit, thereby obtaining an error. Check to determine whether the check digit is correct (step
1500, 1510).

(2) If the check in step 1510 is not correct, a flag indicating that the ID code is invalid is set in the transmission buffer to the host computer in order to notify the host computer of the invalid ID code, and the process ends (step 1570).

After this processing, the information that the ID code is invalid is notified to the host computer 5, and the voice file number for prompting the data retransmission to the order terminal 1 from the host computer 5 is instructed to the voice response device 4, and the voice response A voice such as “ID code is invalid. Please transmit again.” Is output from the device 4 to the user of the telephone 2.

(3) If the check for the check code of the ID code in step 1510 is correct, then the order record is checked. That is, the first order record is fetched from the memory 45, and it is determined whether or not the order number is a sequential number and whether the check result of the check digit is correct (steps 1520 to 155).
0).

(4) If the checks in steps 1540 and 1550 are both correct, it is determined that the contents of the order record are correct,
The host computer sets the order record together with the ID code in the transmission buffer to be notified (step 1560).

(5) If an error occurs in the sequential numbering check and check digit check of the order number in steps 1540 and 1550, the next order record is taken out, and the processing from step 1520 is executed again.

(6) During the processing of steps 1520 to 1560, the record is updated to the position of the delimiter code. If the final order record is determined in step 1530, this reception analysis processing is ended.

After the processing by the above-mentioned reception analysis program is completed, the voice response apparatus 4 activates a communication request program for the host computer 5, and transmits the ID record and the order record set in step 1560 to the computer interface 46. , 51 via the host computer 5
To send to.

The host computer 5 determines the ID in the received ID record.
A code, a master file check of the product code in the order record, a stock check of the product, and the like are performed. If an order is possible, the product code or the order number of the processed order is returned to the user in order to reply to the user. Of voice file number and variable word data. Voice response device side 4
Combines the voice file number and the variable word data received from the host computer 5 and, for example, "Orders # 1, # 2, and # 3 have been accepted. The total is 10,000 yen." Is output to the user.

The embodiment of the present invention described above includes an ID code,
It is assumed that the record length of the order code and the like is fixed, and the record length is known in advance to the voice response device side.

According to the above-described embodiment of the present invention, a check digit for error detection is added to each order record for transmission. Therefore, even if a reception error occurs due to one transmission error, the error is transmitted to another order record. It does not affect all data, only the reception error of the corresponding record is required, and other normal records can be normally received by the voice response device 4.

For this reason, according to the above-described embodiment of the present invention, it is possible to improve the degree of completion of the order entry service using the voice signal communication method using the PB signal, and to store the order record for which the order processing was successfully performed. Since the user can be notified by voice, the order contents can be clarified to the user.

Next, a description will be given of another embodiment of the present invention capable of further improving the reliability of the transmission of the order data by the PB signal transmitted from the order terminal.

In this embodiment, PB signals having poor transmission quality representing numbers 2, 3, 6, etc. are replaced with PB signals representing A, B, D, etc., and transmitted.

FIG. 16 is a functional block diagram illustrating the principle of a PB signal receiver in the voice response device 4, FIG. 17 is a diagram illustrating a truth value for determining a PB signal, and FIG. 18 is a diagram illustrating values of used frequencies. ,
FIG. 19 is a diagram for explaining the frequency characteristics of the PB signal, and FIG. 20 is a diagram for explaining the processing procedure in the embodiment of the present invention by the PB signal replacement process. In FIG. 16, reference numeral 62 denotes a low-pass filter, 63 denotes a high-pass filter, 64 denotes an L-group output controller, 65 denotes an H-group output controller, and 71 to 74 and 81 to 84 denote bandpass filters.

In general, the PB signal is configured by selecting one frequency from each of the four frequencies belonging to the low group and the four frequencies belonging to the high group, and combining them. And
The four frequency H ₁ to H ₄ belonging to four frequency L ₁ ~L ₄ and the high group belonging to low group, are determined in the frequency shown in FIG. 18, PB formed by combining these The truth value of the signal is determined as shown in FIG.

The PB signal receiver 42 that receives the PB signal configured as described above includes a low-pass filter 62, a high-pass filter 63, band-pass filters 71 to 74, and 81 to 8 as shown in FIG.
4 and output controllers 64 and 65.

In the PB signal receiver configured as described above, a low-pass filter 62 extracts a low-frequency component of the PB signal from the input PB signal 61. Next, each of the low group frequencies L ₁ = 697 Hz, L ₂ = 770 Hz, L ₃ = 853 Hz, L ₄ = 941 Hz
, One low-group frequency signal included in the PB signal is identified and output. This output is output to the output terminal as a digital output “1” or “0”, respectively, depending on whether or not the output level of the filter has exceeded a certain threshold.

Similarly, from the input PB signal 61, a high-frequency component of the PB signal is extracted through the high-pass filter 63. Further, as described above, each of the high group frequencies H ₁ = 1209 Hz and H ₂ = 13
36Hz, H ₃ = 1477Hz, through a band-pass filter 81-84 of each H ₄ = 1633 Hz, the frequency signal of one high group included in the PB signal is identified output. This output is output to the output terminal as a digital output “1” or “0”, respectively, depending on whether or not the output level of the filter has exceeded a certain threshold value.

The outputs of the band-pass filters 71 to 74 are input to an L-group (low-group) output controller 64. The L-group output controller determines whether or not the outputs of the band-pass filters 71 to 74 continue for a certain period of time. It is checked whether the level difference from the high group frequency is within a certain range, whether there is only one effective output among the four outputs, and the like. The high group frequency is also input to the H group output controller 65 that performs the same control, and the same check is performed.

If the check results in both output controllers are both OK, the SP (Sterling Pulse) signal is turned on, and the acquisition of the received PB signal is instructed.
The illustrated PB signal receiver is ready for receiving the next PB signal.

Note that the L-group output controller 64 and the H-group output controller 65 are not the absolute values of the output levels of the bandpass filters, but the relative level differences between the output levels of the low-pass and high-pass bandpass filters within a certain range. A check is performed to determine whether or not the PB signal is undetectable due to weakening of the audio level.

That is, the L group output controller 64 and the H group output controller 65 turn on the SP signal when only one output of the low-pass bandpass filter and one output of the high-pass bandpass filter are output, At this time, the signals output from the two band-pass filters indicate the two frequency components constituting the received PB signal. With these two frequency components and the truth code shown in FIG. 17,
PB code can be determined.

Next, for example, the circuit shown in FIG.
The operation will be described assuming that the PB signal 61 has been input.

When the PB signal is input to the circuit shown in the figure, the low group frequency L ₁ is extracted by the low-pass filter 2, and this signal is output via the band-pass filter 21. The L group output controller 64 checks whether or not the output signal has continuity for a predetermined time, whether or not the output level exceeds a threshold value, and whether or not the other three outputs are invalid. High-group is also similarly processed frequency, the output of the high frequency group H ₃ is obtained.

When the output condition of the L group output controller 64 and the H group output controller 65 is satisfied by the above, next SP signal is on, the code indicating the truth value of FIG. 17, the frequency L ₁ and H ₃
PB code “3”, which is the intersection of

As described above, the PB signal transmitted from the order terminal 1 is converted into digital data by the PB signal receiver 42 in the voice response device 4 based on the above-described principle.

The PB signal transmitted from the order terminal 1 is normally transmitted to the voice response device 4 as a two-frequency signal as shown in FIG.
Due to the structure of the PB signal, reflection from the carbon microphone in the mouthpiece of the telephone 2, etc., a case where the second harmonic component is superimposed on the PB signal occurs.

 This is shown in FIG.

The PB signal in the normal case is as shown in FIG.
Although it is composed of only two frequencies of the low group and the high group, the problem here is when the above-mentioned second harmonic is generated. That is, as shown in FIG. 19 (b), when the second harmonic of the low group frequency is superimposed on the high group frequency and a level difference occurs between the low group frequency and the high group frequency of the PB signal, the voice response The PB signal receiver 42 in the device 4 cannot accurately detect the PB code. Such a phenomenon easily occurs in the PB signals “2”, “3”, and “6” in which the second harmonic of the low group frequency is relatively close to the high group frequency.

Therefore, in another embodiment of the present invention, a PB signal that does not overlap with the high group frequency even when the second harmonic of the low group frequency of the PB signal occurs is used.

That is, in this embodiment, PB signal is considered that the second harmonic of the low frequency group L ₁ is superimposed on the high frequency group "2", "3", respectively, PB signal "A", "B "the, PB signal" 6 "replacement using the, PB signal is considered that the second harmonic of the low frequency group L ₂ is superposed on the high frequency group" is intended to be used by replacing the D ".

The processing procedure in this embodiment is shown in FIG.

In FIG. 20, first, order data is input to the order terminal 1. After the order data is input, the order terminal 1 calculates and adds an error detection check digit to the order data (boxes 2005 and 2010).

Thereafter, the order terminal 1 sends the PB signals “2”, “3” and “6”
Is transmitted with the PB signal in which “A”, “B”, and “D” are replaced, respectively (Box 2015).

Therefore, the PB signals “2”, “3” and “6” do not pass through the speaker 11 of the order terminal 1, the mouthpiece of the telephone 2, and the public network 3. The receiver 42 receives the order data based on the PB signal.

Among the order data based on the PB signal received by the PB signal receiver 42, the PB signals “A”, “B”, “D”
Replaced by PB signals “2”, “3”, “6” (box 202
Five).

Thereafter, the voice response device 4 calculates and checks the check digit, and if the check is correct, transmits the order contents to the host computer (boxes 2030 to 20).
40).

Thereafter, the voice response device 4 converts the processing result of the host computer 5 into voice and notifies the user of the result, as in the embodiment described above.

According to the other embodiment of the present invention described above, since the PB signal can be transmitted and received without being affected by the second harmonic of the low group frequency of the PB signal, the audio signal communication system using the PB signal The effect that the reliability of the data transmission in can be improved.

Next, the structure and operation method of the order terminal 1 will be described with reference to the drawings.

FIG. 21 is a diagram showing an appearance of the order terminal, FIG. 22 is a diagram showing an example of a catalog, FIG. 23 is a flowchart for explaining the operation of the order terminal, and FIGS. 24 to 32 are tables of a display accompanying the operation. It is a figure showing an example.

The order terminal 1 has an internal configuration as already described in FIG. 2, but further includes a power supply voltage detecting section, and a function of displaying a dead battery on the display 12 when the battery voltage falls below a certain level. Can be provided. Also,
As shown in FIG. 21, the operation surface includes a display 12 using an LCD or the like, a speaker 11, a numeric keypad, an ON / OFF key for turning on / off the power, and other various function keys (these various types). The function key is provided with a keyboard 13 including a terminal operation which will be described later.

The operation for placing an order using the order terminal 1 with reference to a catalog as shown in FIG. 22 is executed as follows according to the flow shown in FIG.

(1) First, turn on the power by pressing the ON key. As a result, the member code is displayed on the display 12, and the menu selection screen is displayed. Although the member code is described later, it corresponds to the ID code in the above-described embodiment (box A).

(2) Next, if an injection button is pressed among the "order", "arrangement" and "send" buttons used for menu selection, it is checked whether or not an order has been placed before this operation. If there is no previous order data, the project number is entered and the "plan number" flashes (box
I).

(3) Here, a plan number (four digits) is entered with a ten key to identify the type of catalog. At this time, an underbar is displayed on the display 12 so that the required input digit can be recognized. When the user inputs, for example, a plan number 1234 from the numeric keypad, the display on the display 12 changes as shown in FIGS. 24 to 26, and displays the inputted plan number.
Confirm that this display matches the plan number in the catalog,
When the "registration" key is pressed, a beeping sound is heard, the entered project number is stored in the memory, the display data is erased, and the product code input mode is set. As a result, the "product code" flashes, and the required input digits are displayed as underbars. At this time, the order number from 01 on the left two digits of the screen
Numbers are automatically assigned and displayed up to 50 (box c).

(4) In this state, for example, when ordering bread, the ten keys 1, 2, and 3 are pressed in order to input the order product code 123 in the same manner as described above. The display at this time is as shown in FIG. After entering this product code, the system automatically enters the next quantity input mode, “Quantity” flashes, and the required digits are displayed as underbars (Box d).

(5) Input the quantity (two digits). For example, to input ten quantities, the ten keys 1 and 0 are pressed. As a result, the display becomes as shown in FIG. When the "registration" key is pressed after the input of the quantity, a beeping sound is made, and the input product code and quantity are stored in the memory. After that, the order number is incremented by one, and the display as shown in FIG. 29, in which the product code blinks, is performed. By repeatedly inputting the product code and quantity of the next order in the same manner as described above, the order data is input, and when the input of the order number 50 is completed, END is displayed (box E).

(6) Repeat the above operation to input all the data to be ordered, and then press the △ and ▽ keys to decrease or increase the display of the order number of the order entered so far. You can confirm the order with the order number NO.

(7) In addition, if the order entry is once completed, the power is turned off, and then the power is turned on again, if the order key is pressed in the state of the box above, the display shown in (box key) will be displayed. The order contents can be confirmed by pressing the ▽ and 確認 keys.

(8) If an error is found in the above-described confirmation operation, the order content can be corrected by pressing the correction key while the order content is displayed. For example, when correcting the ordered product code 129 to 123, the product code 129 is displayed, and when the correction key is pressed, the product code “129” blinks as shown in FIG. Here, a new product code 123 is input. This will cause the display to
As shown in FIG. After that, the quantity will be automatically entered in the same way as described above. If the quantity needs to be corrected, enter a new quantity. Push. At this time, a beep sounds and the input product code and quantity are registered in the memory. If the quantity is a single digit (0-9), 1
After inputting only the digits, pressing the “register” key also causes the memory to be registered.

(9) Next, when only the quantity is to be corrected, the order contents to be corrected are displayed using the ▽ and △ keys, and when the “correction” key is pressed, a product code indicating the ordered product, for example, “123”
Flashes. At this time, press the “Registration” key. By pressing the "register" key, the quantity correction mode is set, and "quantity" and "10" blink. Individually, for example, the quantity
To correct from 10 to 01, press numeric key 1. As a result, the display on the display becomes as shown in FIG. 32,
Then, when the "register" key is pressed, a beeping sound is heard and the corrected quantity is registered in the memory.

The above-mentioned member code is a code registered for each terminal in order to identify an orderer in a cooperative or the like, and may generally be an ID code or the like. Then, when placing an order, this order code is sent to the head of the order data to allow the order receiving side to identify the orderer. Further, this member code can be prevented from being tampered by performing a secret operation such that the member code can be input after the password is input so that the member cannot change the member code without permission.

By the order input operation as described above, order data can be input, confirmed, and corrected to the order terminal, and the order data can be stored in the memory of the order terminal.

When the order data is stored, if there is a telephone, call the center, check the response, set the mouthpiece on the speaker of the order terminal, and press the send button to place the order. The data is transmitted and order data can be entered directly into the computer. Transmission of order data by the transmission button is possible any number of times,
Data can be easily retransmitted.

In the above-described order input operation of a product, the product code and the quantity are input. However, the unit price of the product may be further input.

In this case, at the end of the input operation, the total price of the order can be calculated and displayed in the order terminal, and the user can check the total price of the product ordered by the user. Also, after transmitting the order data, it is possible to check the total amount of the ordered goods, which is responded from the voice response device, to check.

Further, in general, the product catalog changes in a certain period, thereby changing the plan number. When such a change is made, the order data with the previous plan number stored in the order terminal becomes unnecessary and needs to be deleted.

In the present invention, when a new plan number is input to the order terminal, the order data of the previous plan number is cleared from the memory, thereby performing an operation for clearing the memory when ordering a new plan. It can be unnecessary.

 The details of this operation will be described with reference to FIG.

When the order terminal is turned on and the order key is pressed, the plan number flashes. If you enter a new project number here, the order terminal confirms that the order data stored in the memory has been sent and that the entered project number is different from the stored project number Then, assuming that the entered project number has been updated,
Clear the order data from the previous project in the memory and put the display in the boxed state to enter the order data with the new project number.

Thus, an order based on a new project can be performed by automatically clearing the previous order data, that is, without performing an operation for clearing.

Also, in the ordering operation described with reference to FIG. 23, it is assumed that up to 50 items can be ordered, but this number can be arbitrarily set according to the memory capacity.

Furthermore, when ordering more than the number of items that can be set at one time, once the maximum number of order data is transmitted, the host computer as the center device accepts the order data, and the same order data is created again. And send it. In this case, the previous order data can be automatically cleared from the memory as in the case described above.

After the transmission is completed, the user can listen to the voice response from the voice response device at the center, check the content, and check the data transmission state.

 Next, another embodiment of the order terminal will be described.
