Description
Technical Field
The invention belongs to the field of cash register, and particularly relates to a display system for a cash register.
Background
With the continuous acceleration of urbanization process in China, large shopping malls are built like bamboo shoots in spring after rain. When the current shopping supermarket is used for manual cash collection, the prior shopping supermarket generally arranges in line for payment in sequence, and collects the cash of the next customer after the previous customer finishes the cash collection. However, when the customer needs to pack the scanned goods, and the cashier device calculates the amount due by the customer, the customer needs to open the wallet or the corresponding payment software to pay again, during which the cashier can only assist or wait for the customer to pack the goods, and wait for the customer to open the wallet or the corresponding payment software to pay, but cannot pay the next customer, which reduces the cashier efficiency.
In order to improve the cash register efficiency, the cash register needs to be designed to simultaneously register two adjacent customers, that is, when the previous customer prepares for payment, the cashier can scan the goods purchased by the next customer, but the traditional cash register system only has one display facing the customer, and is used for displaying the information of the currently scanned goods and displaying the total price information of all the goods after the scanning of all the purchased goods is completed. If a display is still used in the design of the cash register system, the display can only display the price information of the goods purchased by one customer, for example, after the scanning of the goods purchased by the current customer is completed, the display must display the total price information of all the goods purchased by the customer, so as to provide payment reference for the previous customer and prepare for payment. Since the price information on the display of the previous customer during the preparation for payment is not changeable, the price information of the commodity purchased by the next customer scanned by the cashier during the preparation for payment by the previous customer cannot be displayed, so that the next customer cannot know the price information of the currently scanned commodity, thereby reducing the good purchase experience of the next customer.

Referring to fig. 1, a block diagram of an embodiment of a display system for a cash register according to the present invention is shown. The system can comprise a cash register scanning device 1, a cash register processing device 2, an input device 3, a first display 4 and a second display 5, wherein the second display 5 is positioned behind the first display 4, a cashier scans the commodity information of each commodity purchased by a first customer through the cash register scanning device 1, and the cash register scanning device 1 sends the commodity information of each commodity purchased by the first customer to the cash register processing device 2; after all the commodities purchased by the first customer are scanned, the cashier sends a first customer scanning completion signal to the cashier processing device 2 through the input device 3; after that, the cashier scans the commodity information of each commodity purchased by a second customer adjacent to the first customer behind the first customer through the cash registering and scanning device 1, and the cash registering and scanning device 1 sends the commodity information of each commodity purchased by the second customer to the cash registering and processing device 2; after all the commodities purchased by the second customer are scanned, the cashier sends a second customer scanning completion signal to the cash registering processing device 2 through the input device 3; the cashier processing device 2 judges whether a first customer scanning completion signal is received or not after receiving commodity information of commodities purchased by a first customer, if so, the total price information of all commodities purchased by the first customer is displayed on the first display 4 and the second display 5, and if not, the currently scanned price information of the commodities purchased by the first customer is displayed on the first display 4 and the second display 5; after receiving the scanning completion signal of the first customer, judging whether commodity information of commodities purchased by a second customer is received, if so, replacing the total price information on the second display 5 with the price information of the currently scanned commodities purchased by the second customer, and if not, keeping the total price information on the second display 5 unchanged; after receiving the commodity information of the commodities purchased by the second customer, judging whether a scanning completion signal of the second customer is received or not, if the scanning completion signal of the second customer is received, replacing the price information on the second display 5 with the total price information of all the commodities purchased by the second customer, judging whether the first customer completes payment or not, if the payment is completed, replacing the total price information on the first display 4 with the total price information of all the commodities purchased by the second customer, and if the payment is not completed, keeping the total price information on the first display 4 unchanged; if the scanning completion signal of the second customer is not received, whether the first customer completes the payment is judged, if the payment is completed, the total price information on the first display 4 is replaced by the price information of the commodities purchased by the second customer which are scanned currently, and if the payment is not completed, the total price information on the first display 4 is kept unchanged.
In this embodiment, in order to simultaneously receive cash from two adjacent clients, the cash register further includes a cash register display device 6 as shown in fig. 2, and on the side of the cash register display device 6, the cash register displays the scanned commodity information so as to provide a cash register reference to the cashier. The cashier processing device 2 displays the commodity information on the right half part of the cashier display device 6 in a list form each time the cashier processing device receives the commodity information of the commodity purchased by the first customer, and sets all the commodities purchased by the first customer to be in a state of waiting for payment after receiving the scanning completion signal of the first customer; each time the commodity information of the commodity purchased by the second customer is received, the commodity information is displayed on the left half side of the cash register display device 6 in a list form, and after a second customer scanning completion signal is received, all the commodities purchased by the second customer are set to be in a state of waiting for payment.
When two left and right commodity information lists are displayed on the cash register display device 6, a cashier selects the commodity information lists positioned on the left half side and the right half side of the cash register display device through the input device 3, after the commodity information list on the corresponding side is selected and a corresponding payment confirmation signal is sent to the cash register processing device 2 through the input device 3, the cash register processing device 2 settles all commodities purchased by the corresponding client, sets all commodities purchased by the corresponding client to a paid state after payment is completed, and cancels the display of all commodity information lists purchased by the corresponding client on the cash register display device 6; when only one commodity information list is displayed on the cashier display device 6, the cashier directly sends a corresponding payment confirmation signal to the cashier processing device 2 through the input device 3, the cashier processing device 2 settles all commodities purchased by the corresponding customer, sets all commodities purchased by the corresponding customer in a paid state after payment is completed, and cancels the display of all commodity information lists purchased by the corresponding customer on the cashier display device 6.
When the cashier receives the cash, the cashier firstly scans the commodity purchased by the first customer, and after the scanning is finished, the corresponding key in the input device can be pressed, so that the input device sends a scanning completion signal of the first customer to the cash receiving processing device. After all the goods purchased by the first customer are scanned, the first customer may be bagging the goods or preparing for payment, and conventionally, a cashier needs to wait for the customer to complete the preparation for payment before cash can be collected. According to the invention, after the cashier scans all the commodities purchased by the first customer and presses the corresponding keys in the input device, all the commodities purchased by the first customer are not directly settled, but enter a state to be paid. If the cashier finishes scanning all the commodities purchased by the first customer, the first customer finishes payment preparation, only one commodity information list is displayed on the cash register display device at the moment, the cashier can press a corresponding key in the input device to enable the input device to send a payment confirmation signal of the first customer to the cash register processing device, the cash register processing device settles all the commodities purchased by the first customer after receiving the payment confirmation signal of the first customer, sets all the commodities purchased by the first customer in a paid state after payment is finished, and cancels the display of all the commodity information lists purchased by the first customer on the cash register display device.
In actual operation, a cashier needs to press a corresponding key in the input device twice to provide instructions on whether scanning is finished and whether payment is carried out for the cash registering processing device, so that the cash registering processing device can accurately express the current executable instruction in order to realize good interaction, and after receiving a corresponding scanning completion signal and a corresponding payment confirmation signal, the cash registering processing device adopts different colors to display the left half side or the right half side of the cash registering display device. For example, for the product information displayed on the right side, the cashier uses the black font to display before sending the scanning completion signal to the cashier processing device through the input device, and the cashier uses the green font to display after sending the payment confirmation signal to the cashier processing device through the input device, so that the cashier can determine whether the cashier processing device receives the corresponding signal, and a good human-computer interaction interface can be realized.
In addition, if the cashier finishes scanning all the commodities purchased by the first customer, the first customer does not finish the payment preparation, the cashier can scan the commodities purchased by the second customer, after the cashier finishes scanning all the commodities purchased by the second customer, the cashier presses the corresponding key in the input device, the input device sends a second customer scanning completion signal to the cash register processing device (namely, after the first customer finishes the payment preparation after the second customer finishes scanning all the commodities purchased by the second customer), if the first customer still does not finish the payment preparation, the default selection frame is positioned at the left half side, the cashier can press the corresponding key in the input device, the input device sends a second customer confirmation payment signal to the cash register processing device, the cash register processing device settles all the commodities purchased by the second customer after receiving the second customer confirmation payment signal, and after the payment is finished, setting all the commodities purchased by the second customer to be in a paid state, and canceling the display of the information list of all the commodities purchased by the second customer on the cash register display device.
If the cashier finishes the payment preparation during the scanning of the commodities purchased by the second customer, the cashier can move the selection frame to the right side through a left key and a right key in the input device, then press a corresponding key in the input device to send a payment confirmation signal of the first customer to the cashier processing device, the cashier processing device settles all the commodities purchased by the first customer after receiving the payment confirmation signal of the first customer, sets all the commodities purchased by the first customer to be in a paid state after the payment is finished, and cancels the display of an information list of all the commodities purchased by the first customer on the cashier display device. After the first customer completes payment, the purchased commodity list information of the second customer is displayed on the left half side of the cash register display device, the first customer leaves the counter after completing payment, the second customer moves forwards, and if the purchased commodity of the second customer is still displayed on the left half side of the cash register display device, when the purchased commodity of the next customer of the second customer is scanned, the purchased commodity list information of the next customer can only be displayed on the right half side of the cash register display device, so that the association of the commodity and the corresponding customer by a cashier is not facilitated. Therefore, when the cash register processing device displays the product information list on the left half side of the cash register display device after the first customer settles and pays for all the products purchased, the cash register processing device displays the product information list on the left half side of the cash register display device in a state of being placed on the right half side of the cash register display device. According to the invention, after the first client finishes payment, the commodity information list displayed on the left half side is sent to the right half side for display, so that continuous cash collection can be ensured, and a cashier can accurately associate a bill with the client, thereby improving the cash collection accuracy. Therefore, when the former client of the two adjacent clients is preparing for payment, the invention can scan the commodity purchased by the latter client, thereby improving the cash-collecting efficiency and ensuring the cash-collecting accuracy.
In the above embodiment, the display of the cash register display device is preferably controlled. For each customer, when receiving the commodity information of the first commodity purchased by the customer, the cash register processing device allocates a unique identification symbol to the customer, sets the state of the identification symbol to be scanning, and associates all the commodity information purchased by the customer with the identification symbol, wherein each identification symbol has three states: the cashier processing device is used for scanning the state, the state to be paid and the paid state, a first queue and a second queue are locally stored, the first queue inserts and deletes identification symbols of all customers starting from a first customer, the second queue inserts and deletes identification symbols of all customers starting from a second customer, when the states of the head identification symbols in the first queue and the second queue are the paid state, the head identification symbols are correspondingly deleted from the first queue and the second queue, when the right half part of the cashier display device is displayed, a commodity information list corresponding to the head identification symbols in the first queue is searched, and the searched commodity information list is displayed; when the left half part is displayed, firstly, whether the head identification symbols in the first queue and the second queue are the same or not is judged, if so, no display is carried out, if not, the commodity information list corresponding to the head identification symbols in the second queue is found, and the found commodity information list is displayed. After receiving the commodity information, the cashier processing device searches the identifier with the scanning state from the head part in the first queue, and associates the commodity information with the searched identifier. After receiving the scanning completion signal, the cashier processing device searches for the identifier with the scanning state from the head of the first queue, and sets the identifier with the to-be-paid state. When the cashier processing device receives the selection signal and the payment confirmation signal on the right side, the payment is performed on the commodity corresponding to the head identifier in the first queue; and when the selected signal of the left half side and the payment confirmation signal are received, the commodity corresponding to the head identifier in the second queue is settled.
In the following, examples are given: when scanning a first commodity purchased by a first customer, a cashier allocates an identification symbol A to the first customer, inserts the identification symbol A into a first queue, sets the state of the identification symbol A to be scanning, after all commodities purchased by the first customer are scanned, the cashier can send a scanning completion signal to a cashier processing device through an input device, the cashier processing device searches the identification symbol A in the scanned state from the head of the first queue, and sets the state of the identification symbol A to be in a state to be paid. After the cashier scans all the commodities purchased by the first customer, if the first customer is ready for payment, at this time, only the identifier a corresponding to the first customer exists in the first queue, the status of the identifier a is in a state to be paid, the second queue is empty, so that the cashier display device only displays commodity list information corresponding to the identifier a on the right half side, at this time, the default selected frame is located on the right half side, after the cashier processing device receives the payment confirmation signal, the head identifier a in the first queue is searched, the commodities corresponding to the identifier a are settled, after the payment is completed, the cashier processing device sets the status of the identifier a to be paid, and the identifier a is deleted from the first queue.
After the cashier scans all the commodities purchased by the first customer, if the first customer is not ready for payment, the cashier can send a scanning completion signal to the cashier processing device through the input device, so that the state of the identifier symbol A is set to be a state to be paid, then the commodities purchased by the second customer are scanned, and similarly, when the cashier processing device receives information of the first commodity purchased by the second customer, the identifier symbol B is distributed to the second customer, the state of the identifier symbol B is set to be scanned, and the identifier symbol B is respectively inserted into the first queue and the second queue. At this time, the first queue and the second queue have different head identifiers, and therefore, the left half side of the cash register display device displays the commodity information associated with the head identifier in the second queue. If the cashier finishes the payment preparation of the first customer during the scanning of the commodity purchased by the second customer, the cashier can move the selection frame to the right side and send a payment confirmation signal to the cashier processing device through the input device, the cashier processing device settles the commodity corresponding to the head identifier in the first queue after receiving the selection signal and the payment confirmation signal of the right side, and the cashier processing device sets the state of the identifier A to be a paid state after the payment is finished and deletes the identifier A from the first queue. At this time, since the head identifiers in the first queue and the second queue are the same, the left half of the cash register display device does not display the product associated with identifier B, and the right half displays the product associated with identifier B.
If the cashier has scanned all the commodities purchased by the second customer, and presses the corresponding keys in the input device to make the state of the identifier symbol B be the state to be paid, and the first customer still has not finished the preparation for payment, the cashier can directly send a payment confirmation signal to the cash register processing device through the input device, at this time, the default selection frame is positioned on the left half side of the cash register display device, the cash register processing device settles the head identifier symbol B in the second queue after receiving the selection signal and the payment confirmation signal on the left half side, and the cash register processing device sets the state of the identifier symbol B to be the paid state after the payment is finished and deletes the identifier symbol B from the second queue. After the second customer completes the payment, the payment preparation of the first customer is usually completed, so the cashier can check the first customer, and similarly, the status of the identifier a is the paid status after the payment is completed, and the identifier a and the identifier B in the first queue are deleted in sequence. The invention realizes the display of the commodity information and the execution of the settlement by utilizing the two queues and the related logic, has simple control mechanism, and a cashier only needs simple operation without respectively setting corresponding keys and corresponding keys aiming at two customers.
On the basis of simultaneously cashing two adjacent customers, the invention adopts two displays to display the price information of the commodities purchased by the front and the back adjacent customers, thereby ensuring that the two adjacent customers can check the price information of the commodities purchased by the customers and ensuring the good shopping experience of the customers. The cashier of the cashier processing device 2 can scan the commodities purchased by two adjacent customers in sequence, so that when the cashier processing device 2 does not receive the scanning completion signal of the first customer, the cashier processing device 2 can show that the cashier processing device 2 does not receive the commodity information of the commodities purchased by the second customer, the first customer can be at the second display or the first display, and at the moment, the first display 4 and the second display 5 can display the currently scanned price information of the commodities purchased by the first customer, so that the first customer can view the price information of the commodities purchased by the first customer regardless of the position. When the cashier processing device 2 receives the first client scanning completion signal, it indicates that the cashier has scanned all the commodities purchased by the first client, and at this time, the cashier processing device 2 settles the balance of all the commodities purchased by the first client and displays the total price of all the commodities purchased by the first client, and also because it cannot be determined whether the first client is located at the first display or the second display, and the commodities purchased by the second client are not scanned and do not care about the price of the commodities purchased by the second client, the cashier processing device displays the total price information of all the commodities purchased by the first client on both the first display and the second display.
The cashier processing device indicates that all the commodities purchased by the first customer are scanned after receiving the scanning completion signal of the first customer, the commodity information received by the cashier processing device is the commodity information of the commodities purchased by the second customer, and the second customer concerns the price information of the commodities purchased by the second customer, because the second display is located behind the first display and the second customer is located behind the first customer, the first customer will usually move to the first display after all the goods purchased by the first customer are scanned, therefore, after receiving the commodity information of the commodity purchased by the second customer, the cash register processing device replaces the total price information displayed on the second display with the currently scanned price information of the commodity purchased by the second customer, therefore, the price information of various commodities purchased by the second customer can be conveniently checked by the first customer during the preparation of payment.
The cash register processing device judges whether a second customer scanning completion signal is received or not after receiving the commodity information of the commodities purchased by the second customer, if the second customer scanning completion signal is received, all the commodities purchased by the second customer are scanned, and at the moment, the second display used for displaying the price information to the second customer displays the total price information of all the commodities purchased by the second customer. If the first customer is ready for payment after the scanning of all the commodities purchased by the second customer is completed, the cashier should pay the first customer with priority, and after the payment of the first customer is completed, the first customer does not need to view the total price information of the commodities purchased by the first customer any more, while the second customer may still be at the second display, or move forward to the first display when the first customer leaves the first display, so that the display that the second customer may view has the first display and the second display, and at this time, the cashier processing device not only displays the total price information of all the commodities purchased by the second customer on the second display, but also displays the total price information of all the commodities purchased by the second customer on the first display for the second customer to view. If the first customer is not ready for payment after the cashier scans all the goods purchased by the second customer, the first display still needs to display the total price information of all the goods purchased by the first customer so as to provide a reference for the payment of the first customer.
If the cash register processing device does not receive the scanning completion signal of the second customer, the cash register processing device indicates that the commodities purchased by the second customer are not scanned completely, and at the moment, the second display is still required to display the price information of the currently scanned commodities purchased by the second customer. When the cashier scans the commodities purchased by the second customer and the first customer is ready for payment, the cashier should preferentially check the cash of the first customer, after the payment of the first customer is completed, the first customer does not need to check the total price information of the commodities purchased by the first customer, the second customer may still be at the second display or move forward to the first display when the first customer leaves the first display, so that the displays which the second customer may check include the first display and the second display, and at the moment, the cash register processing device not only displays the currently scanned price information of the commodities purchased by the second customer on the second display, but also displays the currently scanned price information of the commodities purchased by the second customer on the first display so as to be checked by the second customer. If the first customer is not ready for payment during the time that the cashier scans the items purchased by the second customer, the first display still needs to display the total price information of all the items purchased by the first customer so as to provide a reference for the payment of the first customer.
The embodiment shows that when two adjacent customers receive cash at the same time, the two displays are adopted to control the contents displayed on the two displays, so that the two adjacent customers can obtain the price information which the customers want to check, and the good purchasing experience of the customers can be ensured.
