Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an order entry system for ordering products, and particularly to an order entry system for automatically accepting orders for products via a public communication network, for example, a telephone line. The present invention relates to an order entry terminal device having an ordering function and suitable for use in configuring an order entry system.

[Prior Art] In recent years, order entry in which orders for products are placed from households has become commonplace.

Order entry from general households like this can be done electrically,
Conventional techniques related to mechanical methods include a PB signal communication method using a push-button telephone and a voice response device, a personal computer communication method using a personal computer, and a barcode input method using a barcode reader. There are known techniques to do this.

Each of these techniques has the following problems.

That is, in those using the PB signal communication method, it is necessary to manually press the push button in a timely manner, and the operation is complicated. In addition, conventional technology that uses computers, barcode readers, etc. has been slow to spread into general households because these terminals are too expensive, and even if they do become widespread, they are difficult to accept due to poor operability. There is a fear that they will not be able to receive it.

Further, as another conventional technique, an order entry method using OCR, which has been supported by recent improvements in character recognition technology, is known. This conventional technology requires off-line input and collection processing of OCR sheets, so the turnaround time from ordering to delivery of the product is long, making it unsuitable for urgent orders.

That is, its operation is performed by the following method.

The product seller regularly distributes product catalogs and OCR sheets to users, and the users fill out the ○C1 sheet with the necessary ordered products, quantities, etc., and send it to the product seller. The seller of the product inputs the collected OCR sheet into the computer as data using the computer's oCR reader, and then causes the computer to perform processing according to the order.

As described above, in the conventional technology using OCR, input is performed offline, resulting in a long turnaround time from placing an order to receiving the product.

Therefore, an ordering terminal using the PB signal system was once again accepted as an inexpensive and compact ordering terminal that can be accepted in general households, is easy to operate, can place orders in real time (short turnaround time), and is easy to use. It's starting to get worse. The reason behind this is that the type of microphone on the phone
It cannot be overlooked that carbon microphones, which were a major cause of PB signal deterioration, have been replaced with condenser microphones, and that the use of condenser microphones has improved the quality of PB signal transmission.

Now, in order entry using the conventional PB signal system, cancellation of order contents, change in quantity, and additional orders are performed as explained below.

That is, in this conventional technology, P sent from the order terminal
Information on whether the order is for ordering a product or for canceling the order is added to the order data from the B-time signal, and such order data is sent to a PB signal receiving device such as a voice response device, for example. The receiving device then determines whether to order or cancel the order, and depending on the result, processes the order or cancel, respectively.

As mentioned above, in the conventional technology using the PB signaling system, - in order to cancel the ordered contents, it is necessary to input the cancellation contents to the order terminal and send them to the receiving side device at the same time; - If you want to change the quantity of the products you have already ordered, you will need to cancel the order data mentioned above and then order the required number of products again. In order to do so, it is necessary to enter the order data into the order terminal again and place the order.

In addition, as a conventional technique regarding order entry as described above, for example, Hitachi Hyoron Vol. 63° No. 12r
The technology described in the input/output device J for a voice response system is known.

[Problem to be solved by the invention] The conventional technology using OCR mentioned above saves labor on the order receiving side,
No consideration was given to rationalization, and the problem was that computer processing could not be performed without distributing and collecting OCR sheets for hundreds of thousands of people.

Further, there was a problem in that the accuracy of OCR reading could not be improved because no consideration was given to accurately receiving orders from customers, and various customers were required to write characters for OCR.

Further, no consideration was given to ease of ordering by customers, and there was a problem in that customers could not place orders unless they filled out an OCR sheet and delivered it to a designated location by the deadline.

In addition, in the above-mentioned conventional technology that uses PB double signals, when canceling the ordered contents or changing the quantity, it is necessary to newly confirm the quantity of the canceled product, the changed product, and input it into the order terminal. , When reducing the quantity, it is necessary to cancel, reorder, and send a PB signal twice.
This has the problem that the operations for this are extremely complicated.

In addition, after repeatedly canceling and reordering, the orderer may become unsure of the final status of the order.
This poses a problem in that a situation arises in which the order has to be delivered in time to the order center.

The purpose of the present invention is to solve the problems of the prior art described above,
By using a public communication network such as a telephone line from the customer's home or other location, the order details can be sent after confirming the line connection to the ordering party, and the order details can be transmitted from the ordering party. To provide an easy-to-use order entry terminal device that can be confirmed based on the announcement content and can close the line after the confirmation to complete the product order.

Another object of the present invention is to input order details using buttons;
Another object of the present invention is to provide an order entry terminal device that allows confirmation of order details.

Still another object of the present invention is to provide an order entry terminal device that allows data to be easily retransmitted when an error is notified by an announcement from the ordering party after transmission.

[Means for Solving the Problems] According to the present invention, the object is to provide an order terminal with a keyboard, a display for displaying the order input from the keyboard, a memory for storing order data, and an order data. This is achieved by comprising a PB signal transmitter that converts into a PB signal, a speaker that can be coupled to send order data based on the PB multiplied signal to a mouthpiece of a telephone, and a CPLJ that controls these.

Further, the above object is achieved by making it possible to place an order through the procedure of batch transmission of order data and voice confirmation of the transmission result.

For this reason, the communication control unit,
A voice response device including an automatic voice response section and a voice signal reception section, and a host computer are provided.

[Operation] The ordering terminal is configured with a keyboard, display, speaker, memory, and CPU, and allows the orderer to enter the order details using the keyboard while looking at the catalog, and at the same time confirm the entered details on the display. can do. In addition, since the entered order details are stored in the memory, it is possible to check and change the entered details at any time after placing the order.

Then, by pressing the transmit key, the data stored in the memory from the speaker can be converted into an audio signal based on the PB double signal and output, so just by placing the mouthpiece of the telephone on the speaker, you can connect the telephone line to the speaker. Order data can be sent to.

On the center side, there is a communication control unit, automatic voice response unit,
A PB signal receiving section and a control section that controls these, processes received data, and inputs the received data to the host computer are provided.

Then, the center-side device automatically receives a telephone call from the orderer, requests the orderer to send voice signal data, and then converts the transmitted voice signal into data at the voice signal receiving unit. The data is reversely converted and processed in the computer section, and a voice response can be returned to the orderer according to the result, so the order data can be input directly from the terminal to the host computer.

In addition, the receiving side, that is, the center side, can be operated unmanned, resulting in labor savings.

The PB signal oscillator 20 oscillates a PB multiplied signal as instructed by the CPU 17, and outputs this PB multiplied signal as an acoustic signal via the speaker interface 14 and the speaker 11.

Next, a description will be given of processing operations when ordering products, etc., according to an embodiment of the present invention configured as described above.

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

(1) A user of the order entry system according to the present invention uses the keyboard 13 to enter his or her ID on the order terminal 1.
In addition to inputting the code, while looking at the catalog of already distributed products, enter the catalog code, the product code of the product you want to order, and the quantity (data input).

During this input process, the input numbers are displayed on the display 12, so the user can work while confirming the input.

Further, the various input data are stored and held in the backup battery RAM 19, and the contents are held even if the main power of the order terminal 1 is cut off.

It should be noted that when inputting this data, input errors may occur, so the person in charge can modify the entered data, add the number of ordered products, etc.

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

(3) On the other hand, the voice response device 4, which has detected an incoming call signal from the public network 3 by the communication control unit 41, performs an incoming call operation (response to the called call) using this communication control unit 41, and communicates with the telephone 2. Form a path (incoming call).

(4) At this time, the voice response bag M4 normally sends a message such as "This is ○○○
is. Please send. ” etc. will be sent back. The audio output for this purpose is generated by the C-PU 44, which receives the incoming call report from the communication control unit 41, from a digital audio file (for example, 64K) stored in the disk 47.
bps μ-1aw PCM audio) and converting it into analog by the D/A converter 43, and the communication control unit 41. It is sent to the telephone set 2 via the public network 3.

(5) When the user confirms that the call has been received by the voice response device 4 as described above, the user places the mouthpiece of the telephone 2 on the position of the speaker 11 of the ordering terminal l, and uses the keyboard 13 to store the call in the backup battery RAM 19. The ordered data is converted into a PB signal by the PB signal oscillator 20, and a trigger is given to send it to the speaker 11, thereby transmitting the order data (transmission).

(6) On the other hand, the voice response device 4 receives and analyzes the voice signal based on the PB double signal transmitted from the order terminal 1 using the PB receiver 42, converts it into a digital value, and stores it in the memory 45. . Upon receiving this audio signal, the audio response device:
In order to increase the reliability of acoustic communication methods using PB double signals,
The voice response device 4 side also uses the check digit for error detection given on the order terminal 1 side using an error detection method such as a checksum for transmitted data, which has been agreed upon in advance between the order terminal 1 and the voice response device 4. Check and
The reliability of the data received from the order terminal l is improved.

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

As shown in Figure 3, this data includes an order message code to distinguish it from a cancellation message, and an ID for order form identification.
code, catalog code, order number 2, which is a serial number of the product that is automatically given by the order terminal sequentially for each ordered product, the product code, its quantity, and the end of the data sent 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 aforementioned delimiter code.

If there is an error in the received data due to a check digit error, the voice response device 4 will issue a voice requesting retransmission, such as ``A reception error has occurred.'' Please send again. An audio file such as J is read 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.

Also, the user can use the mouthpiece of telephone 2 as an ordering terminal! When transmitting order data through the speaker 11 of the order terminal 1, when the data transmission from the order terminal 1 is completed, the user is notified of the completion by, for example, the sound of a buzzer. , the user will put the receiver to his/her ear in order to listen to the response 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 notified order product code and the disk 54.
The order file corresponding to each ID code is checked against the product master file corresponding to the catalog code stored in the disk 54 and the inventory quantity of each product corresponding to the catalog code stored in the disk 54. is created in the disk 54.

This order file is updated with each additional order that is added until the applicable catalog code is valid, that is, until immediately before order processing is performed based on the applicable order file. In addition, when creating such an order file,
An order reception number is assigned to each order so that each order file can be specified for each ID code.

That is, the order file is created using the ID code and order reception number as keys.

(9) The host computer 5 further sends a reply audio file number to the voice response device 4 in order to reply to the user whether there are any products that cannot be ordered due to a product master check error, lack of stock, etc. and notify the reception number that the order cannot be placed and the order reception number (answer).

(10) The voice response device 4 reads from the disk 47 the voice of the reply voice file number, the non-orderable order number, and the order acceptance number received from the host computer 5 via the computer interface 46, and combines the respective voices. For example, [The product with order number (No. 2) is not in the catalog. The order reception number is (1234).

Please check. ” etc. is notified to the user's telephone 2 via the D/A converter 43 and the communication control unit 41 (answer voice).

In this case, the reply voice file number in the voice response device 4 described above must be stored in the host computer 5 in advance. Also, as a response voice,
You can prepare the total amount of ordered products, request for resending, voice of thanks, etc., and use them in any combination.

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

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

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

An orderer who wishes to cancel an order inputs data using an order terminal according to the data format shown in FIG.

In other words, when canceling an order, the user must
．． D code, catalog code, and order reception number output from the voice response device 4 when the order is completed.

After inputting the product code to be canceled, the voice response device 4 is called by the 1i telephone 2, and the two are connected. In this state, in order to transmit the cancellation data input earlier from the ordering terminal 1, place the mouthpiece of the telephone 2 on the speaker 11 of the ordering terminal L, and press the trigger from the keyboard 13 to transmit the cancellation data. give. This trigger causes
A cancellation message code is automatically added to the input data for cancellation, and this cancellation data is converted into a PB signal by the PB oscillator 20 and output from the speaker 11.

Thereafter, 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 order acceptance number in the received cancellation data as keys, and reads out the canceled product code in the cancellation data from the disk 54. The data is deleted from the order file or rewritten to invalid data, and stored again in the disk 54 using the ID code and order reception number as keys.

If you wish to increase or decrease the quantity of the ordered product, you may perform a new order operation after performing the above-mentioned cancellation operation, or you may change the quantity of the product to be increased or decreased without performing the cancellation operation. It is sufficient to simply perform an order operation with an order reception number assigned to the order. In this case, since there is a new order that duplicates the previous order reception number, the host computer 5 invalidates the previous order and stores the new order in the file.

Next, an example of order entry will be described in which order contents can be canceled, quantity changed, and additional orders can be made through the same procedure.

Figure 5 is a diagram explaining the operating procedure of the order terminal when canceling an order, changing the quantity, or placing an additional order after placing an order. 12 is a flowchart illustrating an overview of message reception processing on the host computer side when performing the above.

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

First, the previously transmitted order data stored in the order terminal 1 is displayed on the display using function keys such as line feed. Next, for example, when a correction key is pressed, the product code 123 flashes to prompt correction of the product code.

When the enter key is pressed in this state, the product code 123 is reset to the memory as it is, and the quantity OO flashes to prompt the user to correct the quantity. Here, if you correct the quantity to OO and press the enter key, this quantity of 00 will be registered in the memory.
This means that the quantity of product code 123 is registered as 00.

After the memory in the ordering terminal has been rewritten in this way, the voice response device is called using the telephone and communication is performed using the voice signal using the PB double signal, just as in the case of a normal order. The order details are entered into the host computer via the response device. In this case, the order details of products having order numbers other than 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 explained using the flow shown in Figure 6. (1) First, it is determined whether the received message is an order message or not. If the message is , other message processing (not shown) is performed (step 600).

(2) If the determination in step 600 is an order message, the order file with 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 used as the order file. If it does not exist in the order file, it is assumed that there is an order for a new product, and the product code and its order quantity are added to the order file as a code (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 set to the quantity of the corresponding product code set in the order message. Replace it with the quantity (step 640).

(4) It is determined whether the product code in the order message to be searched is the final data. If it is not the final data, the process returns to step 620 and repeats the process related to the next product code. If it is the final data, the order file is written from the memory 53 to the disk 54 and the process is completed (steps 650 and 660).

In the quantity change procedure shown in FIG. 5(b), it is sufficient to perform exactly the same procedure as in the cancellation procedure described above.
All you have to do is change the quantity data of the ordered product so that it becomes the absolute quantity you currently want. In this case, as in the case of the cancellation procedure described above, R
After registering the changed product code and quantity in the AM, call the voice response device 4 using the telephone 2, perform voice signal communication using the PB double signal, and send the message to the host computer 5 via the voice response device 4. Enter the order details.

In this case, of course, the order details for products with order numbers other than order number 05 stored in the order terminal 1 are simultaneously transmitted to the voice response device! Then, on the host computer 5 side,
The same process shown in FIG. 6 as in the case of cancellation is executed.

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

Now press the input key to enter a new product code, for example 456, and store this product code 456 in the RAM! Register at 9,
Next, press 08 and enter key to register the current absolute quantity of the product, for example o8, in R, AM19.

In this case, as in the case of the cancellation procedure described above, after registering the product code and quantity added to the order terminal in the RAM 19, the telephone 2 is used to call the voice response device 4, and the voice response by the PB double signal is sent. Perform signal communication and voice response device 4
The order contents are entered into the host computer 5 via the order number 01 along with the contents of the order number o5. In this case as well, the process shown in FIG. 6 is executed on the host computer 5 side as in the case of order cancellation.

According to the above-described embodiment of the present invention, - After placing a supporting order, the operation of the ordering terminal when canceling the order, changing the quantity, or placing an additional order is performed in the same procedure as when placing an order. This makes it possible to provide an order entry service that is easy to use for users. Furthermore, according to the above-mentioned embodiment, the same program can be used for processing on the host computer side for all processes of new orders, cancellations, quantity changes, and additional orders. It is possible to obtain the effect that the number of development steps during development can be reduced.

Furthermore, according to the above-described embodiment of the present invention, the order details stored in the order terminal always indicate the latest order details, so it can be used to confirm when the product has been delivered. , the absolute number of order details can be grasped simply by looking at the memory contents of the order terminal.

Above, we have explained the configuration example and operation of an order entry system using voice signal communication using PB double signals.Next, I)
Another embodiment of the present invention using a modified example of audio signal communication using B signals will be described.

Another embodiment of the present invention is a PB transmitted from an order terminal.
A start code is added to the beginning of the data based on the double signal.

Fig. 8 is a diagram showing the format of data based on the PB multiplied signal when a start code is added, and Fig. 10 shows the operation of the voice response device 4 when receiving data based on the PB multiplied signal to which a start code is added. This is a schematic flowchart for explaining, and will be described below.

In the format shown in Figure 8, the start code is
This is automatically given by the order terminal l. Furthermore, although the order message code and catalog code shown in FIGS. 3 and 4 are not provided in FIG. 8, these codes may be provided.

(1) When order data having a data format as shown in FIG. ), the received data is not buffered until a start code is received, the received data is read, and if the received data is a start code, the start code is read. Perform buffering (step 1000.1゜2)
0).

(2) Next, determine whether or not the data has ended by sending a telephone call by monitoring the reception of the delimiter code (for example, #).
The received data after receiving the start code is buffered until the start code is received (step 1040.r06o).

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

Note that in the general flowchart shown in FIG. 10, if the start code and delimiter code cannot be received, the process falls into an infinite loop, so in another embodiment of the present invention, the time from the start of reception to the end of reception is monitored. ,or,
The maximum allowable number of digits for buffering can be determined, and if the number of time-over digits is exceeded, the reception processing can be terminated as a reception error.

Next, we will explain a method that can avoid reception errors due to unreceivable control codes such as start codes and delimiter codes (even if these control codes cannot be received, the data itself is normal). do.

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

In this example, @), n consecutive tart signs and n consecutive delimiter codes are added, and the order data with these added is,
The order terminal l sends the message to the voice response device 4. In this case, the voice response device performs processing such that if it is able to receive even one of a plurality of consecutive start codes and delimiter codes, it is deemed that the start code and delimiter code have been received.

(1) Determine whether the received data is a start code or not, do not buffer the received data until the start code is received, and when the start code is received, buffer the received data, that is, the start code. (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, the received data is buffered (steps 1120 and 1130).

(3) From then on, as in the case of the process explained in FIG. The reception process ends (steps 1140 to 1160).

Figure 12 is a sequence diagram when the PB signal code is transmitted from the ordering terminal 1 to the voice response device 4 without adding a start code, and Figure 13 is a sequence diagram when the PB signal code is transmitted with a start code.
FIG. 4 is a sequence diagram when transmitting a signal code.

In FIGS. 12 and 13, it is assumed that a button on the telephone 2 is pressed by mistake before the data is transmitted by the PB signal code from the ordering terminal 1, and the signal is received by the voice response device 4. .

In this case, in the example of FIG. 12 which does not have a start signal,
Because 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, a check digit is checked on the voice response device 4 side. When this happens, a reception error occurs.

However, if there is a start code as shown in Figure 13, the range of data due to the PB double signal transmitted from order terminal l becomes clear, so ■ It is possible to prevent reception of invalid data on the voice response device 4 side due to the PB double signal button, and it is possible to prevent received data errors due to missing start codes and delimiter codes, and the voice signal due to the PB double signal can be prevented. The reliability of data transmission in the communication method can be improved.

Next, we will introduce a method that can further improve the reliability of data transmission, that is, the order data based on the PB double signal sent from the order terminal 1 is divided into record units, and a check digit for error detection is added to each record. A method for transmitting a voice response device to a voice response device will be explained.

FIG. 14 is a diagram showing the format of data based on a PB multiplied signal in which a check digit for error detection is added to each record, and FIG. 15 is a flowchart illustrating the reception analysis operation on the voice response device side in this case. In addition, the 15th
The flow shown in the figure is the flow of a program that is started after the received data is stored in the memory 45 according to the flow of the reception processing program shown in FIGS. 1O and 11.

(1) First, the ID code in the order data received from the order terminal is retrieved from the memory 45, the check digit of the ID code is calculated, and the check digit is compared with the attached check digit. A check is performed to determine whether the check digit is correct (step +5001510).

(2) If the check in step 1510 is not correct,
To notify the host computer of incorrect ID code,
A flag indicating that the ID code is invalid is set in the transmission buffer to the host computer, and the process is terminated (step 157).
0).

After this process, information that the ID code is invalid is notified to the host computer 5, and the host computer 5 instructs the voice response device 4 to provide a voice file number for prompting the order terminal 1 to resend the data. The rID code is invalid from device 4 to the user of phone 2. Please send again.

” etc. will be output.

(3) If the check digit of the ID code in step 1510 is correct, then the order record is checked. Immediately, the first order record is retrieved from the memory 45, and it is determined whether the order number is a sequential number and whether the check digit check result is correct (step 1).
520-1550).

(4) If both checks in steps 1540 and 1550 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 for notification to the host computer (step 1560).

(5) If an error occurs in the sequential order number check and check digit check in steps 1540 and 1550, the next order record is retrieved 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, and step 153
If the final order record is determined to be 0, this reception analysis process is terminated.

After the processing by the reception analysis program described above is completed, the voice response device 4 starts a communication request program to the host computer 5, and sends the ID record and order record set in step 1560 described above to the computer interface 46. .51 to the host computer 5.

The host computer 5 stores the I in the received ID record.
The voice response device 4 checks the D code, the master file for the product code in the order record, checks the product inventory, etc., and if the order is possible, returns the processed product code or order number to the user. Notify the response audio file number and variable word data. Voice response device side 4
combines the audio file number and variable word data received from this host computer 5, and outputs, for example, [Orders numbered 1, 2, and 3 have been received.

The total is 10,000 yen. ” etc. is output to the user.

Note that the embodiment of the present invention described above uses an ID code,
It is assumed that the record length of the order code, etc. is a fixed length, and the record length is known in advance on the voice response device side.

According to the embodiment of the present invention described above, since a check digit for error detection is attached to each order record and transmitted, even if a reception error occurs due to transmission at one location, the error can be corrected. All other data is not affected, only the reception error of the corresponding record is caused, and other normal records can be normally received by the voice response device 4.

Therefore, according to the embodiment of the present invention described above, it is possible to improve the degree of completion of the order entry service that uses the voice signal communication method using the PB double signal, and to record order records that allow normal order processing. Since the order can be notified to the user by voice, the order details can be made clear to the user.

Next, another embodiment of the present invention that can further improve the reliability of transmission of order data using a PB double signal transmitted from an order terminal will be described.

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

FIG. 16 is a functional block diagram explaining the principle of the PB signal receiver in the voice response device 4, FIG. 17 is a diagram explaining the truth value for determining the PB multiple signal, and FIG. 18 is a diagram showing the values of the frequencies used. , FIG. 19 is a diagram explaining the PB double signal frequency characteristics,
FIG. 20 is a diagram illustrating a processing procedure in an embodiment of the present invention using PB signal replacement processing. In Figure 16,
62 is a low pass filter, 63 is a bypass filter, 6
4 is an L group output controller, 65 is an 8 group output controller, 71 to 74, and 81 to 84 are band pass filters.

Generally, the PB multiple signal is constructed by selecting one frequency from each group out of four frequencies belonging to the low group and four frequencies belonging to the high group and combining them. and,
4 types of frequencies L1 to L4 that belong to the low group and 4 that belong to the high group
The seed frequencies H5 to H4 are determined to be the frequencies shown in FIG. 18, and the PB multiplied signal truth value formed by combining these is determined as shown in FIG. 17.

The PB signal receiver 42 configured as described above for receiving PBB signals includes a low-pass filter 62, a bypass filter 63, and a band-pass filter 71, as shown in FIG.
~74.81~84 and output controller 64.6
5.

In the PF3 signal receiver configured in this manner, the low-pass filter 62 extracts the low frequency components of the input PBB signal 1 from the PBB signal.

Next, one low group frequency signal included in the PBB signal is passed through each of the band pass filters 71 to 74 of each frequency of the low group, = 697 ratio, L = 770 Hz, L = 852 Hz, L4 = 941 Hz. is identified and output. This output is outputted to the output terminal as digital output 1'' or u OI+ depending on whether the output level of the filter exceeds a certain threshold value or not.

Similarly, from the input PBB signal 1, the high frequency component of the PBB signal is extracted via the bypass filter 63. Furthermore, as in the +iii description, each frequency H,=
12091h, t-1, = l 33611z, )
1=l 477tJ l(,=] 63311z through each bandpass filter 81 to
One high frequency signal included in the B signal is identified and output. This output is outputted to the output terminal as a digital output ``bi'' or ``0°'' depending on whether the output level of the filter exceeds a certain threshold value or not.

The outputs of the bandpass filters 71 to 74 are input to an 11th group (low group) output controller 64, and this L group output controller determines whether the outputs of the bandpass filters 71 to 74 continue for a certain period of time. It checks whether the level difference with the high group frequency is within a certain range, and whether only one of the four outputs is valid. I” group output controller 65 performs similar control for high group frequencies.
is entered and a similar check is performed.

If both of the above check results in the surface output controller are OK, S terling P
u1se) signal is turned on, instructing to capture the received PBB signal, and the illustrated PB signal receiver
Prepare for next PBB signal reception.

Note that the above-mentioned group output controller 64 and first group output controller 65 do not measure the absolute value of the output level of each bandpass filter, but control the relative level difference between the output levels of the low group and high group bandpass filters within a certain range. This prevents the I) B signal from becoming undetectable due to weakening of the audio level.

That is, the L group output controller 64 and the 1 group output controller 65 turn on the SP multiplication signal when only one output of the low group bandpass filter and one output of the high group bandpass filter are output, respectively. At this time, the signals output from both bandpass filters represent two frequency components constituting the received PBB signal.

The PB code can be determined using these two frequency components and the truth value code shown in FIG.

Next, in the circuit shown in FIG. 16, for example, the numerical value rr 3
The operation will be explained assuming that the PB signal 61 indicating n is input.

When the P and B signals are input to the circuit shown in the figure, the low group frequency is extracted by the low-pass filter 2, and this signal is further outputted via the band-pass filter 21. 1
The first group output controller 64 checks whether this output signal has continuity for a certain period of time, whether the output level exceeds a threshold value, and whether the other three outputs are invalid. The high group frequency is also processed in the same way, and an output of high group frequency 11 is obtained.

When the output conditions of the L group output controller 64 and the 11 group output controller 65 are satisfied as described above, the SP multiplication signal turns on, and the PB code par 3, which is the intersection of the frequencies L1 and Hl, is turned on by the code indicating the truth value in FIG. ''' can be obtained.

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

Now, the PB double signal transmitted from the ordering terminal 1 is originally transmitted to the voice response device 4 as a two-frequency signal as shown in FIG. There are cases where this second high frequency component of the PB multiplied signal is superimposed due to reflection from the carbon microphone in the mouthpiece of the telephone 2 or the like.

This situation is shown in FIG.

As shown in Figure 19(a), the PB double signal in a normal case is composed of only two frequencies, the low group and the high group.
What becomes a problem here is the case where the second harmonic as described above is generated. That is, as shown in FIG. 19(b), when the second high frequency of the low group frequency is superimposed on the high group frequency and a level difference occurs between the PB multiple signal low group frequency and high group frequency, the voice response device PB signal receiver 42 in 4
In this case, the PB code cannot be detected accurately.

Such a phenomenon is caused by the PB signal 112 ++ 1131 where the second harmonic of the low group frequency is relatively close to the high group frequency.
1i+ 6 ++ tends to occur.

Therefore, in another embodiment of the present invention, even if the second high frequency of the low group frequency of the I)13 signal is generated, it is decided to use a PB multiplied signal that does not overlap with the high group frequency.

That is, in this embodiment, the second high frequency of the low group frequency is superimposed on the high group frequency of the PB signal 1.
12 II II 311 are respectively replaced with the PB multiplied signal I A11 ′′B′°, and the PB multiplied signal I 611 in which the second high frequency of the low group frequency is considered to be superimposed on the high group frequency is obtained. , the PB signal ″′D′
’.

The processing procedure in this embodiment is shown in FIG.

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

After that, the order terminal l receives the PB double signal I 2 u ′
'3'' and '6'', respectively, II A II
Sends order data using the PB double signal replaced with l B II II D II (box 2015).

Therefore, the PB signal 11211'3'' and the PB signal 6'' do not pass through the speaker II of the ordering terminal 1, the mouthpiece of the telephone 2, and the public network 3, and the PB signal 11211'3'' and the
The B signal receiver 42 receives order data based on the PB signal.

Among the order data based on the PB double signal received by the PB signal receiver 42, the PB double signal I A It II B +
+ “D” is the PB multiplied signal I 2 + in the voice response device 4
+II 3 II, II 6 ++ (box 2025).

Thereafter, the voice response device 4 calculates and checks the check digit, and if the check is correct, transmits the order details to the host computer (boxes 2030 to 2).
040).

Thereafter, the voice response device 4 receives the processing results from the host computer 5 in the same manner as in the previously described embodiment.

Convert to audio and notify the user.

According to the other embodiment of the present invention described above, since the PB multiple signal can be transmitted and received without being affected by the second high frequency of the low group frequency of the PI3 signal, the voice signal communication system using the PB multiple signal can be used. It is possible to achieve the effect that the reliability of data transmission can be improved.

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

Fig. 21 is a diagram showing the external appearance of the order terminal l, Fig. 22 is a diagram showing an example of a catalog, Fig. 23 is a flowchart explaining the operation of the order terminal, and Figs. 24 to 32 are diagrams showing the display accompanying the operation. It is a figure showing an example of a display.

The ordering terminal 1 has the internal configuration already explained in FIG. 2, but is further equipped with a power supply voltage detection section, and has a function of displaying a dead battery on the display 12 when the battery voltage drops below a certain level. can have. 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, ON and OFF keys for turning the power on and off, and various other function keys (these various A keyboard 13 is provided with function keys (which will be explained later in conjunction with the explanation of terminal operations).

The operation when placing an order using the ordering terminal 1 with reference to a catalog as shown in FIG. 22 is performed as follows according to the flow shown in FIG. 23.

(1) First, press the ON key to turn on the power.

As a result, the cooperative member code is displayed on the display 12, and a menu selection screen appears. The cooperative member code will be described later, but it corresponds to the ID code in the above-mentioned embodiment (Box A).

(2) Next, "order" used for menu selection
, "Inquiry", and "Send" buttons, when you press the order button, a check is made to see if an order has been placed before this operation, and if there is no previous order data, the project number input state will be displayed. "Project number" flashes (Box I)
.

(3) At this point, enter the project number (4 digits) manually on the numeric keypad to identify the type of catalog. At this time, under par is displayed on the display 121 so that you can know which techniques require input. For example, the user selects project number 12 from the numeric keypad.
34, the display 12 will display the 24th
The screen changes as shown in FIGS. 26 to 26, and displays the input project number. When you confirm that this display matches the project number in the catalog and press the "Register" key, a beep will sound, the entered project code will be stored in memory, the display data will disappear, and the product code will be entered. mode. As a result, the "r product code" flashes, and the required input technique is displayed as under par. At this time, the order number is automatically assigned and displayed in the left two digits of the screen from 01 to 50 (
box cow).

(4) In this state, for example, when ordering bread, to input the order product code 123, press the numeric keypad L, 2.3 in the same manner as described above. The display at this time is as shown in FIG. 27. After entering this product code, the system will automatically switch to the next quantity input mode, the "Quantity" will flash and the required input will be displayed as under par (Box E).

(5) Enter the quantity (2 digits). For example, set the quantity to lO
If you want to enter a code, press the numeric keys l and 0. As a result, the display becomes as shown in FIG. 28. After entering the quantity, press the [Register J] key, a beep will sound,
The input product code and quantity are stored in memory. Thereafter, a display as shown in FIG. 29 is performed in which the order number is incremented by one and the product code flashes.

Enter the order data by repeatedly entering the product code and quantity of the next ordered item in the same way as above.
When the input of order number 50 is completed, END is displayed (box o).

(6) After repeating the above operations and inputting all the data to be ordered, press the △ key and the key.
The display of order number NO0 of the orders entered so far will decrease or increase, allowing you to confirm the order of arbitrary order number NO6 (box power).

(7) In addition, if you turn the power back on after you have finished ordering and turned off the power, if you press the order key in the condition shown in Box A above, the display shown in (Box K) will appear. You can also confirm the order details by pressing the Δ key.

(8) If an error is found in the confirmation operation described above, the order details can be corrected by pressing the correction key while the order details are displayed. For example, when correcting the order product code 129 to 123,
When product code 129 is displayed and the correction key is pressed, product code [i'129. ! 1 blinks as shown in FIG. Here, a new product code 123 is input. As a result, the display becomes as shown in FIG. 31. After that, the quantity will be entered automatically as in the case above, so if the quantity needs to be corrected, enter a new quantity, and if the quantity does not need to be corrected, just click "Register".
Press the key. At this time, a beep sounds and the entered product code and quantity are registered in memory. If the quantity is one digit (0 to 9), it will be registered in the memory in the same way even if you press the "Register" key after inputting only that one digit.

(9) Next, if you want to correct only the quantity, use the Δ key to display the order details you want to correct, and press the "Correct" key.
j will blink, so press the "Register" key at this time. By pressing this "Register" key, the mode enters the quantity correction mode, and "Number ffi, U[m1OJ" flashes.If you want to correct the quantity individually, for example, from ]O to 01, press the numeric key 1.
Press 1°.This causes the display to appear as shown in FIG. 32. After that, when the "Register" key is pressed, a beep will sound and the corrected quantity will be registered in the memory.

Further, the above-mentioned cooperative member code is a code that is registered for each terminal in order to identify an orderer in a consumer cooperative, etc., and may generally be an ID code or the like. When placing an order, this cooperative member code is sent at the beginning of the order data to allow the order receiving side to identify the orderer. Furthermore, this membership code can be made a secret operation so that the membership code can be input after entering the password so that the membership code cannot be changed without permission by the membership, thereby preventing mischief.

Through manual ordering operations as described above, order data can be input, confirmed, and corrected into the order terminal, and the order data can be stored in the memory of the order terminal.

Once your order data is stored, wherever your phone is located,
After calling the center and confirming the response, place the mouthpiece on the speaker of the order terminal and press the send button.The order data will be sent directly to the computer.
You can enter order data. Order data can be sent any number of times using the send button, and data can be easily resent.

In the above-described manual operation for ordering a product, the product code and quantity are input, but the unit price of the product may also be input thereafter.

In this case, at the end of the input operation, the total amount of the order can be calculated and displayed within the order terminal, and the user can check the total amount of the products he or she has ordered. Furthermore, after transmitting the order data, the total amount of the ordered products can be checked by listening to the response from the voice response device.

Additionally, product catalogs are generally changed over a certain period of time, and as a result, project numbers are changed.

When such a change is made, the order data based on the previous project number stored in the order terminal becomes unnecessary and needs to be deleted.

In the present invention, when a new project number is input to the order terminal, the order data of the previous project number is cleared from the memory, thereby making it possible to perform an operation for clearing the memory when placing an order based on a new project. It can be made unnecessary.

Details of this operation will be explained with reference to FIG. 23.

When the m source of the order terminal is turned on and the order key is pressed, the project number flashes. If you enter a new project number here, the order terminal will display a message indicating that the order data stored in memory has already been sent and that the entered project number is different from the saved project number. Please confirm that the project number entered has been updated.
Clears the order data from the previous project in the memory and sets the display to the box state in order to enter order data using the new project number.

Thereby, an order based on a new plan can be placed without automatically clearing the previous order data, that is, without performing any clearing operation.

In addition, in the order operation explained in Fig. 23, up to 50
Although it is assumed that the user can order up to 10 products, this number can be arbitrarily set depending on the memory capacity.

Furthermore, if you place more orders than can be set in - degrees,
-After transmitting the maximum number of order data and having the host computer, which is the center device, accept the order data,
It is only necessary to create and send similar order data again. In this case, as in the case described above, the previous order data can be automatically cleared from the memory.

After the transmission is completed, it is possible to listen to the voice response from the voice response device at the center, check its contents, and check the data transmission status.

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

This embodiment improves the adhesion between the mouthpiece of the telephone and the speaker of the ordering terminal when performing communication by acoustically coupling the speaker provided on the ordering terminal with the mouthpiece of the telephone. This allows transmission of audio signals with frequency characteristics.

The order terminal 1 has an upper case 32 and a lower case 33.
It is configured to have a horizontal slope.

The acoustic coupling section to which the speaker 11 is attached is constituted by the speaker II housed between the two cases and the rubber receiver 34 provided on the upper case 2.

In addition, at the rear of the speaker 11, there is a tube or ribs on the case 32 and the lower case 33 to prevent the transmitted signal sound from spreading into the internal space of the ordering terminal 1 and resulting in unstable frequency characteristics. 36.

As shown in FIG. 34, the ordering device l is constructed with a horizontal inclination, so by simply placing the mouthpiece 37 of the telephone on the rubber receiver 34, the ordering device 1 can be placed as shown in FIG. To,
The mouthpiece 37 of the telephone can be acoustically coupled to the speaker 11 of the ordering terminal 1 easily and reliably. That is, the rubber receiver 34 is composed of a boss 34a and a receiver part 34b, which allows the mouthpiece 37 of the telephone to
The mouthpiece 37 of the telephone can be easily fixed by simply placing the telephone on the ordering terminal 1. In addition, the receiver is provided with a hole 34c next to the rubber 34 for improving acoustic characteristics, and the speaker 1
The frequency characteristics of the acoustic signal output from 1 are optimized for manual use, and the difference in output level due to frequency is reduced.

According to the embodiment of the ordering terminal described above, since the tube is provided at the rear of the speaker 11, it is possible to prevent the transmitted signal sound from spreading into the internal space of the ordering terminal, so that the signal sound with stable frequency characteristics can be produced. can be sent.

In addition, since the ordering terminal is configured to be tilted horizontally, the mouthpiece of the telephone and the speaker of the ordering terminal can be brought into close contact, making it easy to place the handset of the telephone on the ordering terminal. Acoustic coupling can be performed.

The above-described embodiment of the ordering terminal is suitable for use with a 600-type telephone, but in recent years, telephones of various shapes have come into use. The shape of the mouthpiece of a telephone varies depending on the type of telephone.
There may be cases where reliable acoustic coupling cannot be achieved.

Next, still another embodiment of an ordering terminal that can solve the above-mentioned problems will be described.

In this embodiment, the ordering terminal is provided with a jack for connecting an external speaker, and a speaker box that matches the shape of the telephone is prepared.

FIG. 36 is a perspective view showing the external appearance of the ordering terminal, FIG. 37 is a perspective view showing the external appearance of the external speaker, and FIG. 38 is a diagram showing a state in which the mouthpiece of the telephone and the external speaker are coupled. Third

The external speaker 31 can be fixedly coupled to the mouthpiece 37 of the telephone.

According to the ordering terminal according to the embodiment of the present invention, the acoustic coupling state between the mouthpiece 37 of the telephone and the external speaker 31 can be made more preferable and optimal. In particular, this embodiment is effective in terms of ease of use when used in cordless telephones, wall-mounted telephones, etc., which are difficult to connect directly to the speaker of the ordering terminal.

In addition, by preparing multiple types of external speakers with different speaker box shapes to match the shape of the phone's mouthpiece, there is no need to change the shape of the ordering terminal itself. You can also get

[Effects of the Invention] As described above, according to the present invention, order data can be accurately and quickly transmitted to the order receiving side via a public communication network such as a telephone line.

Further, according to the present invention, it is possible to easily and reliably perform acoustic coupling with the mouthpiece of a telephone, so it is possible to order products from any place where telephone service is available.

Furthermore, since it is possible to retransmit the same data after confirmation by announcement, recovery can be easily performed if a communication error occurs.
