Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a method for controlling a point-of-sale terminal includes steps S200, S300, and S400.
And step S200, controlling the sales terminal to enter a sleep mode when the sales terminal is in a standing state.
Specifically, the sales terminal control method is applied to a machine-to-machine communication device, which is an M2M (machine-to-machine communication device) device, and the M2M device integrates core devices such as a CPU, a memory, a power management chip, a radio frequency transceiver, and a PA, and supports a long-distance communication mode of multiple systems such as FDD/TDD-LTE, WCDMA, TD-SCDMA, CDMA2000-EVDO, and GSM, a short-distance wireless transmission mode of bluetooth and WiFi, and a GNSS wireless positioning technology. The M2M device supports an Android operating system and has various interfaces such as LCD MIPI, Camera MIPI, USB, UART, SPI, I2C and audio. The M2M module is the core system preferred scheme of the wireless intelligent product and is suitable for the sales terminal equipment.
The standing state is that the sales terminal is in a state of not performing card reading operation, and at this time, it can be considered that the sales terminal is not inserted with a corresponding card. Under this kind of state, the information that sales terminal need not read outside card carries out the transaction, if continuously open sales terminal will lead to the electric energy extravagant, seriously influences sales terminal's duration. Therefore, when the sales terminal is in this state, it is important to control the sales terminal to enter the sleep mode to reduce power consumption and to extend the cruising ability of the sales terminal.
The machine and machine communication device is provided with a processor, when the sales terminal is in a standing state, the processor controls the sales terminal to enter a sleep mode according to a pre-stored sleep scheme, and the energy consumption of the whole sales terminal is reduced to the minimum. The machine and machine communication device operating the Android system is generally provided with a display screen for displaying transaction amount or card information, so that a user can conveniently realize related transactions. Therefore, the specific step of controlling the sales terminal to enter the sleep mode may be controlling the display screen to be turned off.
In step S300, when the sales terminal is in the sleep mode, it is detected whether an interrupt signal sent by the optical sensor is received.
Specifically, the interrupt signal is a signal generated when the light-sensing device senses that the card approaches the sales terminal. The sales terminal of the embodiment is provided with a light sensing device besides devices required for realizing basic transaction such as a machine and machine communication device, the light sensing device can sense the change of the illumination intensity in the environment, and when the illumination becomes dark or strong in the environment, the light sensing device can sense the change. And sales terminal need insert the card into corresponding draw-in groove in the use, will block light when the card is close to sales terminal, leads to the light of a certain position to darken. Therefore, when the card approaches or is inserted into the sales terminal, the light sensing device can generate an interrupt signal to be sent to the machine and machine communication device of the sales terminal, so that the sales terminal can respond in time.
Further, in one embodiment, the light sensing device is disposed in a card slot of the sales terminal, so that the card can be sensed timely when the user approaches the sales terminal. It can be understood that after the sales terminal enters the sleep mode, the machine-to-machine communication device can still receive the external signal, and the entire sales terminal does not stop operating, but is in a low power consumption operating state, so as to ensure that the sales terminal can enter the operating state in time when the user has a need to use the sales terminal.
And step S400, controlling the sales terminal to exit the sleep mode when the interrupt signal is received.
Specifically, referring to fig. 2, an interrupt GPIO (General purpose input/output) port of the machine-to-machine communication device is communicatively connected to a GPIO port of the light sensing device, and when the light sensing device senses that light is dark, an interrupt signal can be generated and sent to the interrupt GPIO port of the machine-to-machine communication device through the GPIO port to be received by the machine-to-machine communication device. At this time, the processor of the machine-to-machine communication device controls the sales terminal to exit the sleep mode according to the received signal, so that the user can realize the corresponding transaction operation through the sales terminal.
Through the technical scheme, the high-energy-consumption card-approaching sensing system and the card-approaching sensing method can avoid the situation that the sales terminal is in a high-energy-consumption state for a long time, sense that the card approaches, achieve awakening control of the sales terminal, effectively reduce card-reading delay and ensure use reliability of the sales terminal. Meanwhile, the scheme adopts the light sensing device to realize the awakening of the sales terminal, and has stronger operation reliability compared with the button awakening.
Referring to fig. 3, in an embodiment, after step S300, the method further includes step S500.
Step S500, when the interrupt signal is not received, the sales terminal is maintained in the sleep mode.
Specifically, after the sales terminal enters the sleep mode, the machine-to-machine communication device performs an operation of determining whether the machine-to-machine communication device receives the interrupt signal sent by the optical sensing device in real time, and if the machine-to-machine communication device does not receive the interrupt signal, it indicates that the user does not approach the card to the sales terminal, that is, the sales terminal does not have a requirement for transaction operation, so that the sales terminal only needs to be maintained in the sleep mode.
Further, referring to fig. 4, in an embodiment, after step S400, the method further includes step S600.
And step S600, controlling the sales terminal to enter a card reading working state.
Specifically, after the sales terminal exits the sleep mode, in order to ensure that the user can perform online consumption operations of a credit card, a debit card, and other bank cards according to the sales terminal after the card is inserted into the sales terminal, the machine-to-machine communication device controls the sales terminal to enter a card reading working state. The POS machine transmits the information to a bank system of a card issuing through a UnionPay center to complete online transaction and give out transaction information and a printing bill.
Referring to fig. 5, in an embodiment, before step S200, the method further includes step S100.
And S100, judging whether the sales terminal is in a standing state or not through communication with a main controller of the sales terminal.
Specifically, the operation of determining whether the sales terminal is in the standing state is not unique, in this embodiment, since the machine-to-machine communication device needs to receive the control signal sent by the master controller in real time to implement the related transaction operation during the use of the sales terminal, and when the sales terminal is not in use, the two devices do not have the transmission of the control signal. Therefore, whether the sales terminal is in a standing state or not can be judged by detecting the communication between the machine and the machine communication device and the main controller.
And if the sales terminal is in the standing state, executing the operation of controlling the sales terminal to enter the sleep mode when the sales terminal is in the standing state. That is, when no control signal is transmitted between the machine and machine communication device and the main controller, the machine and machine communication device controls the sales terminal to enter a sleep mode, and controls the display screen corresponding to the machine and machine communication device to be turned off, so that the power consumption of the sales terminal is reduced to the minimum, and the endurance time of the sales terminal is effectively prolonged.
Further, with continuing reference to fig. 5, in an embodiment, after step S100, the method further includes: and if the sales terminal is not in the standing state, returning to the step of judging whether the sales terminal is in the standing state or not through the communication with the main controller of the sales terminal. That is, in this embodiment, the processor in the machine-to-machine communication device detects whether the interaction of the control signal occurs between the machine-to-machine communication device and the master controller is performed in real time, and if the signal interaction does not occur between the sales terminal and the standing device, the processor will perform the operation of detecting whether the control signal occurs between the machine-to-machine communication device and the master controller again while implementing the online transaction according to the control signal sent by the master controller. So that when no signal interaction occurs between the machine and the machine communication device and the main controller, the machine and the machine communication device can be found in time, and then the sales terminal is rapidly controlled to enter a sleep mode, and the power consumption is effectively reduced.
Referring to fig. 6, in one embodiment, step S100 includes step S110 and step S120.
And step S110, when the control signal sent by the main controller of the sales terminal is received, timing is started with preset time length.
And step S120, judging whether the control signal sent by the main controller is received again within the preset time length.
Specifically, if the control signal sent by the master controller is not received again, the sales terminal is considered to be in the standing state. In this embodiment, whether the operation of controlling signal transmission is performed between the machine and the machine communication device and the master controller is analyzed, and specifically, whether signal transmission occurs between the machine and the machine communication device within a preset time period is detected. The specific operation is that the processor in the machine and machine communication device starts to time every time after receiving the control signal, whether the control signal from the master controller is received again within the preset time period is judged, and if the control signal from the master controller is received again, the fact that the user still uses the sales terminal is indicated, namely the sales terminal is not in a standing state. If the machine and machine communication device does not receive the control signal from the master controller again within the preset time length, the user does not use the sales terminal, namely the sales terminal is in a standing state.
The method for controlling the sales terminal can detect the running state of the sales terminal in real time, and control the sales terminal to enter the sleep mode in time if the sales terminal is in the standing state. Meanwhile, the light sensing device is arranged at the sales terminal, whether the card is close to the sales terminal or not can be detected through the light sensing device, and the sales terminal is immediately controlled to exit the sleep mode when the card is detected to be close to the sales interruption. Through the scheme, as long as the sales terminal is in the standing state and immediately enters the sleep mode, the sales terminal can be prevented from being in a high energy consumption state for a long time, and the card can be timely sensed to be close through the light sensing device, so that the awakening control of the sales terminal is realized, the card reading delay can be effectively reduced, and the high-reliability card reading device has high use reliability.
Referring to fig. 7, a point-of-sale control device includes a sleep entry module 200, an interrupt detection module 300, and a sleep exit module 400.
The dormancy entering module 200 is used for controlling the sales terminal to enter a dormancy mode when the sales terminal is in a standing state; the interrupt detection module 300 is configured to detect whether an interrupt signal sent by the optical sensor is received when the sales terminal is in the sleep mode; the sleep exit module 400 is configured to control the sales terminal to exit the sleep mode when receiving the interrupt signal.
Specifically, the sales terminal control scheme of the application is applied to a machine-to-machine communication device, which is an M2M (machine-to-machine communication device) device, and the M2M device integrates core devices such as a CPU, a memory, a power management chip, a radio frequency transceiver, and a PA, and supports a long-distance communication mode of multiple systems such as FDD/TDD-LTE, WCDMA, TD-SCDMA, CDMA2000-EVDO, and GSM, a short-distance wireless transmission mode of bluetooth and WiFi, and a GNSS wireless positioning technology. The M2M device supports an Android operating system and has various interfaces such as LCD MIPI, Camera MIPI, USB, UART, SPI, I2C and audio. The M2M module is the core system preferred scheme of the wireless intelligent product and is suitable for the sales terminal equipment.
The standing state is that the sales terminal is in a state of not performing card reading operation, and at this time, it can be considered that the sales terminal is not inserted with a corresponding card. Under this kind of state, the information that sales terminal need not read outside card carries out the transaction, if continuously open sales terminal will lead to the electric energy extravagant, seriously influences sales terminal's duration. Therefore, when the sales terminal is in this state, it is important to control the sales terminal to enter the sleep mode to reduce power consumption and to extend the cruising ability of the sales terminal.
The machine and machine communication device is provided with a processor, when the sales terminal is in a standing state, the processor controls the sales terminal to enter a sleep mode according to a pre-stored sleep scheme, and the energy consumption of the whole sales terminal is reduced to the minimum. The machine and machine communication device operating the Android system is generally provided with a display screen for displaying transaction amount or card information, so that a user can conveniently realize related transactions. Therefore, the specific step of controlling the sales terminal to enter the sleep mode may be controlling the display screen to be turned off.
The interrupt signal is a signal generated when the light sensing device senses that the card is close to the sales terminal. The sales terminal of the embodiment is provided with a light sensing device besides devices required for realizing basic transaction such as a machine and machine communication device, the light sensing device can sense the change of the illumination intensity in the environment, and when the illumination becomes dark or strong in the environment, the light sensing device can sense the change. And sales terminal need insert the card into corresponding draw-in groove in the use, will block light when the card is close to sales terminal, leads to the light of a certain position to darken. Therefore, when the card approaches or is inserted into the sales terminal, the light sensing device can generate an interrupt signal to be sent to the machine and machine communication device of the sales terminal, so that the sales terminal can respond in time.
Further, in one embodiment, the light sensing device is disposed in a card slot of the sales terminal, so that the card can be sensed timely when the user approaches the sales terminal. It can be understood that after the sales terminal enters the sleep mode, the machine-to-machine communication device can still receive the external signal, and the entire sales terminal does not stop operating, but is in a low power consumption operating state, so as to ensure that the sales terminal can enter the operating state in time when the user has a need to use the sales terminal.
Referring to fig. 2, the interrupt GPIO port of the machine-to-machine communication device is communicatively connected to the GPIO port of the light sensing device, and when the light sensing device senses that light is dark, an interrupt signal can be generated and sent to the interrupt GPIO port of the machine-to-machine communication device through the GPIO port to be received by the machine-to-machine communication device. At this time, the processor of the machine-to-machine communication device controls the sales terminal to exit the sleep mode according to the received signal, so that the user can realize the corresponding transaction operation through the sales terminal.
Referring to fig. 8, in an embodiment, after the interruption detecting module 300, the pos control apparatus further includes a dormancy maintaining module 500. The dormancy maintenance module 500 is used for maintaining the sales terminal in the dormant mode when the interrupt signal is not received.
Specifically, after the sales terminal enters the sleep mode, the machine-to-machine communication device performs an operation of determining whether the machine-to-machine communication device receives the interrupt signal sent by the optical sensing device in real time, and if the machine-to-machine communication device does not receive the interrupt signal, it indicates that the user does not approach the card to the sales terminal, that is, the sales terminal does not have a requirement for transaction operation, so that the sales terminal only needs to be maintained in the sleep mode.
Referring to fig. 8, in an embodiment, after the sleep exit module 400, the pos control apparatus further includes a card reading control module 600. The card reading control module 600 is used for controlling the sales terminal to enter a card reading working state.
Specifically, after the sales terminal exits the sleep mode, in order to ensure that the user can perform online consumption operations of a credit card, a debit card, and other bank cards according to the sales terminal after the card is inserted into the sales terminal, the machine-to-machine communication device controls the sales terminal to enter a card reading working state. The POS machine transmits the information to a bank system of a card issuing through a UnionPay center to complete online transaction and give out transaction information and a printing bill.
Referring to fig. 9, in an embodiment, before the dormancy entry module 200, the pos control apparatus further includes a standing detection module 100. The standing detection module 100 is configured to determine whether the sales terminal is in a standing state through communication with a main controller of the sales terminal.
Specifically, the operation of determining whether the sales terminal is in the standing state is not unique, in this embodiment, since the machine-to-machine communication device needs to receive the control signal sent by the master controller in real time to implement the related transaction operation during the use of the sales terminal, and when the sales terminal is not in use, the two devices do not have the transmission of the control signal. Therefore, whether the sales terminal is in a standing state or not can be judged by detecting the communication between the machine and the machine communication device and the main controller.
And if the sales terminal is in the standing state, executing the operation of controlling the sales terminal to enter the sleep mode when the sales terminal is in the standing state. That is, when no control signal is transmitted between the machine and machine communication device and the main controller, the machine and machine communication device controls the sales terminal to enter a sleep mode, and controls the display screen corresponding to the machine and machine communication device to be turned off, so that the power consumption of the sales terminal is reduced to the minimum, and the endurance time of the sales terminal is effectively prolonged.
And if the sales terminal is not in the standing state, returning to the step of judging whether the sales terminal is in the standing state or not through the communication with the main controller of the sales terminal. That is, the interaction of the processor in the machine and machine communication device for detecting whether the control signal occurs between the machine and machine communication device and the main controller is performed in real time, and if the signal interaction does not occur between the sales terminal and the standing device, the processor will perform the operation of detecting whether the control signal occurs between the machine and machine communication device and the main controller again while realizing the online transaction according to the control signal sent by the main controller. So that when no signal interaction occurs between the machine and the machine communication device and the main controller, the machine and the machine communication device can be found in time, and then the sales terminal is rapidly controlled to enter a sleep mode, and the power consumption is effectively reduced.
Further, in an embodiment, the standing detection module 100 is further configured to start timing with a preset duration when receiving a control signal sent by the main controller of the sales terminal; and judging whether the control signal sent by the main controller is received again within the preset time length, and if the control signal sent by the main controller is not received again, considering that the sales terminal is in a standing state.
Specifically, in this embodiment, whether to perform the operation of transmitting the control signal between the machine and the machine communication device and the master controller is analyzed, specifically, whether to perform the operation of transmitting the control signal between the machine and the machine communication device and the master controller is detected within a preset time period. The specific operation is that the processor in the machine and machine communication device starts to time every time after receiving the control signal, whether the control signal from the master controller is received again within the preset time period is judged, and if the control signal from the master controller is received again, the fact that the user still uses the sales terminal is indicated, namely the sales terminal is not in a standing state. If the machine and machine communication device does not receive the control signal from the master controller again within the preset time length, the user does not use the sales terminal, namely the sales terminal is in a standing state.
The sales terminal control device can detect the running state of the sales terminal in real time, and if the sales terminal is in a standing state, the sales terminal is controlled to enter a sleep mode in time. Meanwhile, the light sensing device is arranged at the sales terminal, whether the card is close to the sales terminal or not can be detected through the light sensing device, and the sales terminal is immediately controlled to exit the sleep mode when the card is detected to be close to the sales interruption. Through the scheme, as long as the sales terminal is in the standing state and immediately enters the sleep mode, the sales terminal can be prevented from being in a high energy consumption state for a long time, and the card can be timely sensed to be close through the light sensing device, so that the awakening control of the sales terminal is realized, the card reading delay can be effectively reduced, and the high-reliability card reading device has high use reliability.
Referring to fig. 2, a control system of a point-of-sale terminal includes an optical sensor device 20 and a machine-to-machine communication device 10, the optical sensor device 20 is connected to the machine-to-machine communication device 10, and the machine-to-machine communication device 10 is used for controlling the point-of-sale terminal according to the above method.
Specifically, the standing state is that the sales terminal is in a state where no card reading operation is performed, and it can be considered that the sales terminal is not inserted with a corresponding card. Under this kind of state, the information that sales terminal need not read outside card carries out the transaction, if continuously open sales terminal will lead to the electric energy extravagant, seriously influences sales terminal's duration. Therefore, when the sales terminal is in this state, it is important to control the sales terminal to enter the sleep mode to reduce power consumption and to extend the cruising ability of the sales terminal.
The machine-to-machine communication device 10 is provided with a processor which controls the sales terminal to enter a sleep mode according to a pre-stored sleep scheme when the sales terminal is in a resting state, so as to minimize the energy consumption of the entire sales terminal. The machine and machine communication device 10 operating the Android system is generally provided with a display screen for displaying transaction amount or card information, which is convenient for a user to realize related transactions. Therefore, the specific step of controlling the sales terminal to enter the sleep mode may be controlling the display screen to be turned off.
The interrupt signal is a signal generated when the light sensing device 20 senses that the card is approaching the point-of-sale terminal. The sales terminal of the present embodiment is provided with the light sensing device 20, in addition to the devices required for the basic transaction such as the machine-to-machine communication device 10, which can sense the change of the intensity of the light in the environment, and can be sensed by the light sensing device 20 when the light in the environment becomes dark or strong. And sales terminal need insert the card into corresponding draw-in groove in the use, will block light when the card is close to sales terminal, leads to the light of a certain position to darken. Therefore, when the card approaches or is inserted into the sales terminal, the light sensing device 20 can generate an interrupt signal to be sent to the machine-to-machine communication device 10 of the sales terminal, so that the sales terminal can respond in time.
Further, in one embodiment, the light sensing device 20 is disposed in a card slot of the point-of-sale terminal so that the user can sense the card approaching the point-of-sale terminal in time.
