BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an order entry system and, more particularly, to an order entry service using an inexpensive communication system using a voice signal from a PB signal transmitting terminal, which can be introduced to ordinary households. The order entry system to be performed.

[0002]

2. Description of the Related Art In recent years, order entry for ordering goods from a general household has become common. As a prior art 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 technology using a barcode input method using a barcode reader is known.

[0003] Each of these techniques has the following problems. That is, in the case of using the PB signal communication system, 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 prior art, an order entry system based on OCR, which is supported by recent improvements in character recognition technology, is known. This prior art requires an off-line input and an OCR sheet collection process, which is unsuitable for urgent orders that require a long turnaround time from order placement to delivery of goods.

[0005] Therefore, as accepted in ordinary households,
As an inexpensive and compact order-only terminal that has good operability and can place an order in real time (short turnaround time), an order terminal based on the PB signal system is being accepted again. Behind this, the type of telephone microphone has been changed from a carbon microphone, which has been a major cause of PB signal degradation, to a condenser microphone, and it should be overlooked that the use of this condenser microphone improves PB signal transmission quality. Can not.

[0006] Cancellation of order contents, quantity change, and additional order in the order entry using the conventional PB signal system have been performed as described below.

That is, according to the prior art, order data based on a PB signal sent from an order terminal is provided with information on the contents of an order for placing an order for a product or the like, or the contents of an order for canceling an order. Is transmitted to a PB signal receiving device such as a voice response device, for example.
An order or cancellation is determined, and the order and cancellation are performed according to the result.

In the prior art using the PB signal system, as described above, in order to cancel the contents once ordered, it is necessary to simultaneously input the cancellation contents to the order terminal and send it to the receiving side device. In addition, when changing the quantity of ordered products, it is necessary to cancel the order data described above and then order the required number of products again. Requires a procedure of inputting order data again to the order terminal and placing an order.

As a conventional technique relating to the order entry as described above, for example, Hitachi Review Vol. 63,
No. Techniques described in No. 12 "Input / output device for voice response system" are known.

[0010]

In the prior art, when canceling the order contents and changing the quantity once, it is necessary to newly confirm the canceled product quantity, the changed product, and input to the order terminal. , If you want to reduce the quantity,
It is necessary to perform two PB signal transmission operations of canceling and reordering, and there is a problem that the operation for the operation becomes very complicated.

[0011] Further, in the prior art, while repeatedly canceling and re-ordering, the orderer loses the understanding of the final state of the order contents, and a situation arises in which an order center must be inquired. There is a problem that it will.

It is an object of the present invention to provide an order entry system which can solve the above-mentioned problems of the prior art and can provide a user-friendly order entry service with good operability. .

[0013]

According to the present invention, an object of the present invention is to input the quantity of an ordered product by a necessary absolute number into data to be transmitted for performing an 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 or reordering by changing the quantity, the order contents ordered previously are corrected and added, and the order contents without change are simultaneously input and retransmitted. Is achieved.
At this time, the information remaining in the order terminal is the final state ordered by the user.

The contents of an order input from the order terminal for ordering a product include a user ID code, a catalog code of a catalog describing the product to be ordered, a product code, a quantity, and the like.

In the case of canceling the order after the order has been placed or changing the quantity, the absolute number required for the reorder quantity, for example,
In the case of cancellation, it is done by inputting zero.
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, which processes the order contents on the receiving side, updates the latest contents sent from the PB signal receiving device such as the voice response device for the contents of the order from the same user during the period when the catalog code is valid. information,
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. The operation of the order processing will be described below with reference to FIG.

(1) The user of the order entry system according to the present invention uses the keyboard 13 and
Enter your ID code and look at the catalog of products already distributed,
Enter the product code and quantity of the product you want to order (data entry).

In this input process, the display 12
At the top, the entered number is displayed, so the user can
Work can be performed 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.

When inputting the data, since an input error or the like may be considered, it is possible to correct the input data once, 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 device 4 having detected the incoming call signal from the public network 3 by the communication control unit 41,
The communication control unit 41 is used to perform an incoming call operation (answered call) to form a path with the telephone 2 (incoming call).

(4) At this time, the voice response apparatus 4 normally checks the incoming call with the calling party, that is, the user.
Return the incoming response voice such as "This is 〇〇〇. Please send." For this purpose, the CPU 44, which has received the incoming call report from the communication control unit 41, searches a digital audio file (for example, a 64 Kbps μ-law PCM audio) stored in the disk 47,
It can be obtained by converting it into an analog signal by the 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 uses the keyboard 13 to operate the backup battery. The order data stored in the RAM 19 is converted into a PB signal by the PB signal oscillating device 20, a trigger for sending the 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. Store. Upon receiving the voice signal, the voice response device checks the data to be transmitted, which is predetermined between the order terminal 1 and the voice response device 4, in order to increase the reliability of the acoustic communication system using the PB signal. The check digit for error detection given by the order terminal 1 by the error detection method such as the sum is also checked by the voice response device 4 so as to improve the reliability of data received from the order terminal 1.

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

As shown in FIG. 3, the data includes an order message code for distinguishing the message from the cancellation message, an ID code for identifying the orderer, a catalog code, and an order terminal for each product to be ordered. It is composed of an order number 2, which is a serial number of a product automatically given in 1, a product code, a quantity thereof, and a delimiter code (for example, #) which is a code indicating the end of data transmitted from the order terminal.

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

If there is an error in the received data due to the check digit error, the voice response unit 4 outputs a voice requesting retransmission, for example, "Reception error has occurred. Please transmit again." The audio file is read out from the disk 47, subjected to analog conversion by the D / A converter 43, and then 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 transmission of the data from the order terminal 1 is completed, the completion is performed, for example, 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) 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 as described above (order).

(8) The host computer 5 receives the order data from the voice response device via the computer interface device 51, and receives the notified order product code,
A check against the product master file corresponding to the catalog code stored in the disk 54 and a check against the stock quantity of each product corresponding to the catalog code stored in the disk 54 are performed. An order file is created in the disk 54.

This order file is added and updated every time there is an additional order until the catalog code 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
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, etc., the voice response device 4 receives a response voice file number, a non-orderable reception number, Notify the order receipt number (answer).

(10) The voice response device 4 reads the voice of the response voice file number, the order impossible order number, and the order reception number received from the host computer 5 through the computer interface 46 from the disk 47, and Combining the sounds, for example, "The product with the order number (No. 2) is not in the catalog. The order reception number is (123
4). Please check. Is transmitted via the D / A converter 43 and the communication control unit 41 to the telephone 2 of the user.
Notify to (answer voice).

In this case, the above-described voice response device 4
It is necessary to hold the reply voice file number 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) With the above processing, the processing of one order is completed, the voice response device 4 and the telephone 2 are turned on, the public network 3 is released, and all the processing is completed (on-hook). ).

Next, the 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 through the order terminal 1 in accordance with the data format shown in FIG.

That is, when canceling an order, the user has his / her own ID code, catalog code, order receipt number output from the voice response device 4 when the order is completed, and
After inputting the product code to be canceled, the telephone 2 calls the voice response device 4 and connects them. In this state, the transmission terminal of the telephone 2 is connected to the speaker 11 of the order terminal 1 in order to transmit the cancellation data entered earlier from the order terminal 1.
On the keyboard 13 to send cancellation data. With this trigger, a cancellation message code is automatically added to the input data for cancellation,
The cancellation data is converted into a PB signal by the PB oscillation device 20 and output from the speaker 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 out 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 a key, and reads out the cancellation data in the cancellation data from the disk 54. It is deleted from the order file or rewritten to invalid data, and the ID code and the order reception number are stored in the disk 54 again as keys.

When increasing or decreasing the quantity of ordered products,
Once the cancellation operation has been performed, a new order operation may be performed.In addition, without performing the cancellation operation, only performing the order operation with the order reception number of the order to increase or decrease the quantity of the product is performed. May be. In this case, the host computer 5 invalidates the previous order and stores the new order in a file because there is a new order that overlaps with the previous order reception number.

Next, cancellation of order contents, quantity change,
An embodiment of an order entry system that can place an additional order by the same procedure will be described.

FIG. 5 is a view 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 view explaining cancellation of the order, changing the quantity, and adding an additional order. 11 is a flowchart illustrating an outline of a message receiving process on the host computer side when performing the following.

The cancellation procedure shown in FIG. 5A is an example in the case where the ordered product code 123 is canceled.

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. Pressing the enter key in this state will cause product code 1
23 is reset in the memory as it is, and the quantity 06 blinks to urge the correction of the quantity. Where the quantity is 0
Correct the value to 0 and press the enter key.
Is registered, and the quantity of the product code 123 is registered as 00.

After the rewriting of the memory in the order terminal is performed in this manner, as in the case of a normal order,
The voice response device is called using the telephone, communication is performed by voice signal using the PB signal, and the order contents are entered into the host computer via the voice 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 flowchart shown in FIG. 6. (1) First, it is determined whether or not the received message is an order message. If the message is a message other than the message, other message processing (not shown) is performed (step 60).
0).

(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 read. Is determined whether it exists in the order file, and if it does not exist in the order file, it is determined that there is an order for a new product,
The product code and the order quantity are added to the order file as one record (steps 620 and 630).

(3) If it is determined in step 620 that the product code in the order message already exists in the order file, the quantity of the corresponding product code in the order file is changed to the value set in the order message. Replace with the quantity of the product code (step 640).

(4) It is determined whether or not the product code in the order message to be searched is the last data. If not, 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 ends (steps 650 and 660).

In the quantity changing procedure shown in FIG.
What is necessary is just to execute the procedure exactly the same as that of the above-mentioned cancellation procedure, and to change the quantity data of the ordered goods so that they may become the absolute quantity which one wants now. Also in this case, as in the case of the above-described cancellation procedure, after registering the changed product code and the quantity in the RAM of the order terminal 1, the voice response device 4 is called by using the telephone 2,
Voice signal communication is performed by the B signal, and the order contents are entered into the host computer 5 via the voice response device 4.

In this case as well, the order contents of the products having the order numbers other than the order number 05 stored in the order terminal 1 are simultaneously transmitted to the voice response apparatus, and the host computer 5 side cancels the order contents. The same processing shown in FIG. 6 is executed.

In the additional order procedure shown in FIG.
After searching for the last record of the previously ordered contents using a function key such as a line feed, the process proceeds 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, a new product code, for example, 456
Press the enter key, and store the product code 456 in the RAM 19
, And then press the input key 08 to register the absolute quantity of the desired product, for example, 08 in the RAM 19.

In this case as well, as in the case of the above-described cancellation procedure, the product code and the quantity added to the order terminal are stored in R.
After registering with the AM 19, the voice response device 4 is called by using the telephone 2, voice signal communication is performed by a PB signal, and the host computer 5 is transmitted to the host computer 5 via the voice response device 4 together with the contents of order numbers 01 to 05. , Enter the order details. Note that, in this case as well, the host computer 5
On the side, the process shown in FIG. 6 is executed as in the case of order cancellation.

According to the above-described embodiment of the present invention, once an order has been placed, the operation of the order terminal when canceling the order, changing the quantity, or making an additional order is performed in the same procedure as when placing the order. As a result, a user-friendly order entry service can be provided. Further, according to the above-described embodiment, the processing on the host computer side can use the same program for all processing of new orders, cancellations, quantity changes, and additional orders. The effect of reducing development man-hours in wear development can be obtained.

Further, according to the above-described embodiment of the present invention,
Since the order contents stored in the order terminal always indicate the latest order contents, it can be used for confirmation when the product is delivered, and the absolute number of the order contents is stored in the order terminal You can grasp just by looking at

While the configuration example and operation of the order entry system using the audio signal communication using the PB signal have been described above, another embodiment of the present invention using a modified example of the audio signal communication using the PB signal will now be described. Will be described.

In another embodiment of the present invention, a start code is added to the head of the data based on the PB signal transmitted from the order terminal.

FIG. 8 shows PB when a start code is added.
FIG. 10 is a schematic diagram illustrating a data format based on a signal, and FIG. 10 is a schematic flowchart illustrating an operation of the voice response apparatus 4 when receiving data based on a PB signal to which a start code is added.

In the format shown in FIG. 8, the start code is automatically assigned by the order terminal 1. 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,
It is determined whether or not the received data is a start code (for example, *). Until the start code is received, the received data is read without buffering the received data. If so, the start code is buffered (step 100).
0, 1020).

(2) Next, whether or not the data is completed is determined by monitoring the reception of the delimiter code, and the received data is buffered after receiving the start code until the delimiter code (for example, #) is received. (Step 104
0, 1060).

(3) If it is determined in step 1040 that the received data is a delimiter code, buffering of the delimiter code is performed to end the reception (step 1080).

In the flowchart of the outline shown in FIG. 10, if the start code and the delimiter code cannot be received, the process goes into an infinite loop. Therefore, in another embodiment of the present invention, the process from the start of reception to the end of reception is performed. The maximum allowable number of digits for time monitoring or buffering is determined, and if the number of digits exceeds the time limit or the number of digits exceeds, the reception process can be terminated as a reception error.

Next, it is possible to avoid 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 itself is normal can be relieved). The method will be described.

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 the order codes are assigned is transmitted to the voice response device 4. . In this case, on the voice response device side,
If one of a plurality of consecutive start codes and delimiter codes can be received, a process is performed that assumes that the start code and the delimiter code have been received, respectively.

(1) It is determined whether or not the received data is a start code. The buffering of the received data is not performed until the start code is received. A ring is performed (steps 1100 and 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, the received data is buffered (steps 1120 and 1130).

(3) Thereafter, similarly to 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. Then, 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. FIG. 13 is a diagram showing a case where a PB signal code is transmitted with a start code added. FIG. 6 is a sequence diagram in a case where the operation is performed.

In FIG. 12 and FIG. 13, before the data is transmitted by the PB signal code from the order terminal 1, the button of the telephone 2 is erroneously pressed, and the signal is
It is assumed that it has been received on the side.

In this case, FIG.
In the example, the data received by the voice response device 4 is different from the data originally sent from the order terminal 1 due to the erroneously pressed signal.
When the check digit is checked on the side, a reception error occurs.

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, the data is erroneously pressed before the data is transmitted from the order terminal 1. It is possible to prevent reception of illegal data on the side of the voice response device 4 due to the PB signal push button, to prevent a reception data error due to lack of a start code and a delimiter code. The reliability of data transmission can be improved.

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

FIG. 14 is a diagram showing a data format based on a PB signal to which an error detection check digit is added for each record, and FIG. 15 is a flowchart for explaining a reception analysis operation on the voice response apparatus side in this case. The flow shown in FIG. 15 stores the received data in the memory 45 according to the flow of the reception processing program shown in FIGS.
It is a flow of a program which is started after being stored in the file.

(1) First, an ID code is extracted from the order data received from the order terminal from the memory 45, and the ID code is obtained.
An error check is performed by calculating a check digit of the D code and comparing the check digit with the added check digit, and it is determined whether the check digit is correct (steps 1500 and 1510).

(2) If the check in step 1510 is not correct, the ID buffer is sent to the host computer in order to notify the host computer of the ID code error.
A flag indicating that the D code is invalid is set, and the process is terminated (step 1570).

After this processing, information that the ID code is invalid is notified to the host computer 5, and the voice file number for prompting the order terminal 1 to retransmit the data from the host computer 5 is instructed to the voice response device 4. Then, the voice response device 4 outputs a voice such as "ID code is invalid. Please transmit again."

(3) If the check for the check digit 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 1550).

(4) Steps 1540 and 1550 described above
If both are correct, it is determined that the contents of the order record are correct, and the order record is set together with the ID code in the transmission buffer notified to the host computer (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 last order record is determined in step 1530, this reception analysis processing is terminated.

After the processing by the above-described reception analysis program is completed, the voice response apparatus 4 starts a communication request program for the host computer 5 and executes the above-described step 15.
The ID record and the order record set at 60 are sent to the host computer 5 via the computer interfaces 46 and 51.

The host computer 5 checks the ID file in the received ID record, the master file check of the product code in the order record, the stock check of the product, and the like. To the user, the voice response device 4
Notify the voice file number and variable word data of the reply. The voice response device 4 combines the voice file number and the variable word data received from the host computer 5,
For example, a voice such as "Orders # 1, # 2, and # 3 have been accepted. Total 10,000 yen" is output to the user.

Note that the embodiment of the present invention described above is
It is assumed that the record length of the ID code, 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, an error detection check digit is added to each order record for transmission, and therefore, even if a reception error occurs due to a single transmission error, the error can be detected. Does not affect all other data, only the reception error of the corresponding record is required, and other normal records are normally transmitted to the voice response device 4.
Can be accepted.

Therefore, according to the above-described embodiment of the present invention, the degree of completion of the order entry service using the voice signal communication system using the PB signal can be improved, and the order processing can be normally performed. Since the user can be notified of the order record by voice, the order contents can be clarified to the user.

Next, 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 will be described. In this embodiment, PB signals of poor transmission quality representing numbers 2, 3, 6 and the like are converted to PB signals representing A, B, D, etc., respectively.
This is replaced with a signal and transmitted.

FIG. 16 is a functional block diagram for explaining the principle of the PB signal receiver in the voice response apparatus 4, FIG. 17 is a diagram for explaining the truth value for determining the PB signal, and FIG. FIG. 19 is a diagram for explaining the frequency characteristic 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.
62 is a low-pass filter, 63 is a high-pass filter, 6
4 is an L group output controller, 65 is an H group output controller, and 71 to 74 and 81 to 84 are band pass filters.

In general, the PB signal is generated from each of the four frequencies belonging to the low group and the four frequencies belonging to the high group.
One frequency is selected and combined. The four frequencies L _{1 to} L ₄ belonging to the low group and the four frequencies H _{1 to} H ₄ belonging to the high group are determined as shown in FIG. 18, and are configured by combining these frequencies. The truth value of the PB signal is determined as shown in FIG.

As shown in FIG. 16, 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, 81 to 84, and Output controllers 64 and 65 are provided.

In the PB signal receiver configured as described above, a low-pass filter 62 extracts low-frequency components of the PB signal from the input PB signal 61. Next, each of the low group frequencies L ₁ = 697 Hz, L ₂ = 7
One low-group frequency signal included in the PB signal is identified and output through each of the band-pass filters 71 to 74 of 70 Hz, L ₃ = 852 Hz, and L ₄ = 941 Hz. 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.

Similarly, from the input PB signal 61, a high-frequency component of the PB signal is extracted through the high-pass filter 63. Further, similarly to the above, each of the high group frequencies H ₁ = 1209 Hz, H ₂ = 1336 Hz, and H ₃ = 1457H
z, each band pass filter 81 to H ₄ = 1633 Hz
Through 84, one high-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 value.

The outputs of the band pass filters 71 to 74 are
L group (low group) output controller 64
The L-group output controller includes a band-pass filter 71
Checks are made as to whether or not the outputs No. to No. 74 have continued for a certain period of time, whether or not the level difference from the high group frequency is within a certain range, and whether or not there is only one effective output among the four outputs. 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 of both output controllers are both OK, SP (Sterling Pulses)
e) The signal is turned on, the receiving of the received PB signal is instructed, and the illustrated PB signal receiver
Prepare for signal reception.

The L group output controller 64, H
The group output controller 65 checks whether or not the relative level difference between the output levels of the bandpass filters of the low group and the high group is within a certain range, not the absolute value of the output level of the bandpass filter. This prevents the PB signal from becoming undetectable due to weakening of the audio level.

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

Next, the operation of the circuit shown in FIG. 16 will be described assuming that, for example, a PB signal 61 indicating a numerical value "3" is input.

When the PB signal is input to the illustrated circuit, the low group frequency L ₁ is extracted by the low-pass filter 2, and the 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.

As described above, when the output conditions of the L group output controller 64 and the H group output controller 65 are satisfied,
The SP signal is turned on, and the PB code “3”, which is the intersection of the frequencies L ₁ and H ₃ , can be obtained from the code indicating the truth value in FIG.

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

Now, the PB signal transmitted from the order terminal 1 is originally transmitted to the voice response device 4 as a two-frequency signal as shown in FIG.
Due to the structure of the loudspeaker 11, the 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.

As shown in FIG. 19 (a), the PB signal in the normal case is composed of only two frequencies of the low group and the high group. This is a case where two harmonics are generated. That is, as shown in FIG. 19B, 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 device 4, the PB signal receiver 42 cannot accurately detect the PB code. Such a phenomenon is caused by the PB signals “2”, “3”, in which the second harmonic of the low group frequency is relatively close to the frequency of the high group.
"6" tends to occur.

Thus, in another embodiment of the present invention,
Even if the second harmonic of the low group frequency of the PB signal is generated, a PB signal that does not overlap with the high group frequency is used.

That is, in this embodiment, the low group frequency L ₁
PB signal second harmonic is considered to be superimposed on the high frequency group "2", "3", respectively, PB signal "A", used by replacing the "B" low group frequency L ₂ Is considered to be superimposed on the high group frequency of the second harmonic of
The B signal “6” is used by replacing the PB signal “D”.

FIG. 20 shows a processing procedure in this embodiment.

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 2).
010).

Thereafter, the order terminal 1 outputs the PB signal “2”,
"3" and "6" are replaced with "A", "B",
The order data is transmitted by the PB signal replaced with “D” (box 2015).

Therefore, the PB signals “2” and “3” are provided to the speaker 11 of the order terminal 1, the mouthpiece of the telephone 2 and the public network 3.
And "6" do not pass, and the order data by the PB signal is received by the PB signal receiver 42 in the voice response device 4.

Among the order data based on the PB signal received by the PB signal receiver 42, the PB signals “A”, “B”,
“D” is the PB signal “2” in the voice response device 4,
It is replaced with “3” and “6” (box 2025).

Thereafter, the voice response apparatus 4 calculates and checks the check digit, and if the check is correct, transmits the order details to the host computer (boxes 2030 to 2040).

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, P
Since the transmission and reception of the PB signal can be performed without being affected by the second harmonic of the low group frequency of the B signal, the reliability of data transmission in the voice signal communication system using the PB signal can be improved. Can be played.

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

FIG. 21 is a view showing the appearance of the order terminal 1, and FIG.
2 is a diagram illustrating an example of a catalog, FIG. 23 is a flowchart illustrating an operation of an order terminal, and FIGS. 24 to 32 are diagrams illustrating display examples of a display accompanying the operation.

The order terminal 1 has the internal configuration as already described with reference to FIG. 2. However, the order terminal 1 further includes a power supply voltage detecting section, and when the battery voltage falls below a certain level, the display 12 indicates that the battery has run out. Function can be provided. Further, as shown in FIG.
A display 12 using D or the like, a speaker 11, and
Numeric keys, ON / OFF key for turning on / off the power,
A keyboard 13 having other various function keys (these various function keys will be described at the same time as the terminal operation described later) and the like are arranged.

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, the power is turned on by pressing the ON key.
And 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, when an order button is pressed among the “order”, “inquiry”, and “send” buttons used for menu selection, it is determined whether or not an order has been placed before this operation. If it is checked and there is no previous order data, the plan number is entered and the "plan number" flashes (box a).

(3) Here, a plan number (four digits) is input by ten keys 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. The user can use, for example,
When the plan number 1234 is input, the display on the display 12 changes as shown in FIGS. 24 to 26, and displays the input plan number. Confirm that this display matches the plan number in the catalog, and press the "Register" key. A beep sounds, the entered plan number is stored in memory, the display data disappears, and the product code is entered. Mode. As a result, the "product code" flashes, and the required input digits are displayed as underbars. At this time, the order numbers from 01 to 50 are automatically assigned and displayed in the left two digits of the screen (box c). (4) In this state, for example,
When ordering bread, the ten keys 1, 2, and 3 are pressed in order to enter 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 10 quantities, the ten keys 1 and 0 are pressed. Thus, the display is 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. Thereafter, 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 item 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) By repeating the above operations and inputting all the data to be ordered, pressing the △ key and the ∇ key, the order number of the order entered so far is displayed.
Is decreased or increased, and any order number NO.
You can confirm the order of (box f).

(7) In addition, when the order input is temporarily completed, the power is turned off, and then the power is turned on again, when the order key is pressed in the state of the above box, (box key)
The order is also confirmed by pressing the ∇ and Δ 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 order 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. Thus, the display is 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. If the quantity does not need to be revised, press the "Registration" key. Push. At this time, a beep sounds and the input product code and quantity are registered in the memory. When the quantity is one digit (0 to 9), even if only the one digit is input, if the "registration" key is pressed, it is similarly registered in the memory.

(9) Next, when only the quantity is to be corrected, the order contents to be corrected are displayed using the Δ and Δ keys, and when the “correction” key is pressed, the product code indicating the ordered product is displayed.
For example, since "123" blinks, "Register"
Press the key. By pressing the "register" key, the quantity correction mode is set, and "quantity" and "10" blink. For example, when correcting the quantity from 10 to 01, the ten key 1 is pressed. As a result, the display on the display becomes as shown in FIG. 32. After that, when the “register” key is pressed, an audible beep sounds and the corrected quantity is registered in the memory.

The aforementioned member code is a code registered for each terminal in order to identify an orderer in a co-op 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. For example, the order data is transmitted, and the order data can be directly input to the computer. The order data can be transmitted by the transmission button any number of times, and the 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 himself. 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.

In general, the product catalog is changed in a certain period, so that the plan number is changed.
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.

According to the present invention, when a new plan number is input to the order terminal, the order data of the previous plan number is
By clearing from the memory, an operation for clearing the memory when an order for a new project is made can be made unnecessary.

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

When the power of 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 of the previous project in the memory and input the order data with the new project number.
Put the display in the boxed state.

As a result, 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.

In the ordering operation described with reference to FIG. 23, it is assumed that a maximum of 50 items can be ordered. However, the number of items can be arbitrarily set according to the memory capacity.

Further, when ordering more than the number of items that can be set at one time, the maximum number of order data is transmitted once, and the host computer as the center device accepts the order data. Data may be created and transmitted. 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 contents, and check the data transmission state.

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

In this embodiment, when communication is performed by acoustically coupling the speaker provided at the order terminal and the mouthpiece of the telephone,
