A first aspect of the present application provides a food material management apparatus 10, and fig. 1 is a schematic structural framework diagram of an embodiment of the food material management apparatus 10 provided in the present application.
Referring to fig. 1, the food material management apparatus 10 includes a near field communication module 11, a control module 12, a power module 13 and a capacitor 14.
Specifically, the near field communication module 11 is capable of performing near field communication with the terminal, and further, performs data transmission with the terminal through the near field communication. Among them, the terminal communicating with the near field communication module 11 may be a mobile terminal, such as a mobile phone, a bracelet, and the like.
The near field communication technology is integrated and evolved from a non-contact radio frequency identification and interconnection and intercommunication technology, and is a short-distance high-frequency wireless communication technology. The devices using the near field communication technology can exchange data in close proximity to each other, that is, the near field communication module 11 can perform near field communication with the terminal when the distance between the material management apparatus 10 and the terminal is within a preset distance.
When the food material management apparatus 10 performs data transmission with a terminal, the food material management apparatus 10 can acquire and store food material management information from the terminal through the near field communication module 11. The food material management information may include information such as a food material mark, a food material name, a storage date, and an expiration date.
Specifically, a terminal performing near field communication with the food material management apparatus 10 is installed with corresponding software in which the user can set food material management information. During the information transmission process of the terminal, the terminal transmits the food material management information to the food material management device 10 based on the software.
Further, the near field communication module 11 may further obtain an induced voltage, specifically, when the distance between the food material management device 10 and the terminal is smaller than the preset distance, the induced voltage is obtained between the near field communication module 11 and the terminal through electromagnetic induction.
In some embodiments, an induction module (not shown) for data transmission and acquiring an induced voltage may be disposed in the near field communication module 11, where the near field communication module 11 may perform data transmission through the induction module, and the near field communication module 11 may also perform charging through the induction module. The sensing module may include an antenna so that data transmission is performed or an induced voltage is acquired by the antenna acting with the terminal.
It should be understood that, in the process that the near field communication module 11 obtains the induced voltage through the induction module, the induction module in the near field communication module 11 may perform electromagnetic induction with the induction module correspondingly arranged in the terminal, so that the near field communication module 11 obtains the induced voltage through the electromagnetic induction.
Of course, in other embodiments, the sensing module in the food material management device 10 may be disposed independently of the near field communication module 11, and the near field communication module 11 is electrically connected to implement communication and voltage transmission.
Further, the near field communication module 11 is provided with a charging port 111, and the induced voltage acquired by the near field communication module 11 can be output from the charging port 111. The near field communication module 11 can control the charging port 111 to be turned on or off, and when the charging port 111 is turned on and the distance between the food material management device 10 and the terminal is within a preset distance range, the induced voltage in the near field communication module 11 can be output through the charging port 111. When the charging port is disconnected, the induced voltage in the near field communication module 11 cannot be output from the charging port 111, and at this time, the near field communication module 11 does not obtain the induced voltage from the terminal.
Further, the control module 12 is in communication connection with the near field communication module 11, and the control module 12 is configured to obtain the food material management information from the near field communication module 12. With the above, after the near field communication module 11 obtains the food material management information from the terminal, the food material management information is stored in the near field communication module 11, so that the control module 11 can obtain the food material management information from the near field communication module 11.
Specifically, the near field communication module 11 is provided with a data area capable of storing food material management information data, and the control module 12 may read data in the data area in the near field communication module 11 through SPI (Serial Peripheral interface) or I2C (Inter-Integrated Circuit) communication, and analyze the data according to a preset rule.
After the control module 12 acquires the food material management information, the control module 12 can control other devices to display the food material management information, so that a user can know the food material management information according to the display information of the devices. The other components may be a part of the food material management apparatus 10, and may be integrated together and provided independently of the food material management apparatus 10.
Further, the power module 13 is electrically connected to the control module 12, and the power module 13 is configured to supply power to the control module 12. When the power module 13 supplies power to the control module 12, the control module 12 can work, and can acquire the food material management information from the near field communication module 11. In conjunction with the above, the device for displaying connected to the control module 12 may also be electrically connected to the power module 13 to supply power to the device.
Further, the first terminal 141 of the capacitor 14 is electrically connected to the charging port 111 and the power module 13, respectively, and the second terminal 142 of the capacitor 14 is grounded. When the charging port 111 is turned on, the induced voltage is output to the first terminal 141 of the capacitor 14, and the capacitor 14 is charged, so that the voltage at the first terminal 141 of the capacitor 14 gradually increases.
In summary, the near field communication module 11 performs near field communication with the terminal when the charging port 111 is disconnected, and at this time, the near field communication module 11 only performs communication without charging any device. The near field communication module 11 charges the capacitor 14 when the charging port 111 is turned on, and the near field communication module 11 only charges the capacitor 14 and does not perform near field communication with the terminal. Therefore, the communication process of the nfc module 11 and the induced voltage obtaining process are not performed simultaneously in the present application.
Further, when the voltage of the capacitor 14 is greater than a preset value, the power module 13 supplies power, which may specifically be as follows:
when the voltage of the capacitor 14 is smaller than the preset value, the power module 13 and the capacitor 14 cannot transmit electric energy, and the power module 13 cannot supply power at this time. When the voltage of the capacitor 14 is greater than the preset value, electric energy transmission can be performed between the power module 13 and the capacitor 14, and the capacitor 14 discharges the power module to supply power through the power module 13, so that the power module 13 supplies power to the control module 12. At this time, the power module 13 stably outputs an operating voltage, which can be used for the control module 12 to stably operate.
In summary, the beneficial effects of the food material management device 10 provided by the present application are further described:
on the one hand, the nfc module 11 does not charge other modules through electromagnetic induction when the terminal performs nfc. Compared with a mode of charging other modules while the near field communication module is in communication, the method can reduce the occupation of a communication electromagnetic field, and further improve the stability and speed of data transmission.
On the other hand, when the voltage of the capacitor 14 is greater than the preset value, the capacitor 1 is powered by the power module 13. Compared with a mode that the induced voltage acquired through the near field communication module directly supplies power to other modules, the power module 13 can output voltage capable of supporting the control module 12 to stably work, so that the control module 13 can stably work, and further, the control module 13 can stably control other devices to display food material management information.
It should be understood that, in the manner of directly supplying power to other modules by obtaining the induced voltage through the nfc module, because the induced voltages provided by different terminals are different in magnitude, when the nfc module obtains a smaller induced voltage from a terminal to supply power to the terminal, the control module may not stably control other devices to display due to insufficient voltage, and then the displayed food material management information may be refreshed many times to cause content flicker or residue.
Therefore, the power module 13 can output a voltage supporting the stable operation of the control module 12, so as to ensure that the control module 13 can stably control other devices to display the food material management information, and thus unstable and incomplete content display caused by insufficient power supply can be prevented.
Fig. 2 is a schematic structural framework diagram of another embodiment of the food material management device 10 provided by the present application.
Referring to fig. 2, in particular, the power module 13 includes an input port 131 and an output port 132, the output port 132 is connected to the control module 12, the input port 131 is connected to the first terminal 141 of the capacitor 14, and the output port 132 outputs the operating voltage Vcc when the voltage of the capacitor 14 is greater than a preset value, so as to supply power to the control module 12.
It should be understood that the specific connection manner between the output port 132 of the power module 13 and the control module 12 is not directly shown in fig. 2, but the connection between the output port 132 and the control module 12 is indicated by outputting the operating voltage Vcc at the output port 132 and inputting the operating voltage Vcc to the control module 12, so that the operating voltage Vcc output from the output port 132 is input to the control module 12.
In conjunction with the above, the voltage of the capacitor 14 can be output from the input port 131 to the power module 13, and the operating voltage Vcc can be output through the output port 132, so as to input the operating voltage Vcc to the control module 12.
In combination with the above, the voltage at the input port 131 of the power module 13 may be equal to the voltage at the first terminal 141 of the capacitor 14, and the operating voltage Vcc output by the output port 132 of the power module 13 may be smaller than the voltage at the input port 131. At this time, the voltage value of the working voltage Vcc is smaller than the preset value.
For example, if the operating voltage Vcc required by the control module 12 during stable operation is set to 3v, the preset value may be set to 5v. When the voltage of the capacitor 14 is greater than 5V, the capacitor 14 can supply power to the power module 13, and the output port 132 stably outputs 3V to the control module 12.
Fig. 3 is a schematic structural framework diagram of a food material management device 10 according to still another embodiment of the present application.
With reference to fig. 3, in particular, the food material management device 10 further includes a display module 15, the display module 15 is electrically connected to the power module 13, the display module 15 is communicatively connected to the control module 12, and the display module 15 is configured to receive and display the food material management information from the control module 12. The control module 12 and the display module 15 are grounded to ensure safety.
Similarly, a specific connection manner between the output port 132 of the power module 13 and the display module 15 is not directly shown in fig. 3, but the connection between the output port 132 and the display module 15 is indicated by outputting the operating voltage Vcc at the output port 132 and inputting the operating voltage Vcc at the display module 15.
With the above, the power module 13 can simultaneously supply power to the control module 12 and the display module 15, and after the control module 12 obtains the food material management information, the control module 12 can send the food material management information to the display module 15 for displaying. The control module 12 may send the food material management information to the display module 15 by means of SPI (Serial Peripheral interface) or I2C (Inter-Integrated Circuit) communication.
In some embodiments, the display module 15 may be an ink screen. After the food material management information is displayed on the ink screen, if the food material management information is not refreshed, the food material management information on the screen is always kept displayed, so that a user can know the food material management information at any time.
Fig. 4 is a schematic structural framework diagram of a food material management device 10 according to still another embodiment of the present application.
In conjunction with fig. 4, in particular, the control module 12 is provided with a discharge port 121, the discharge port 121 is grounded, and the discharge port 121 is electrically connected with the first end 141 of the capacitor 14. When the control module 12 turns on the discharge port 121, the capacitor 14 is discharged through the discharge port 121.
A discharge circuit is formed between the discharge port 121 and the capacitor 14, and when the discharge port 121 is turned on, the discharge circuit is turned on, and the capacitor 14 is discharged through the discharge circuit, so that the voltage at the first terminal 141 of the capacitor 14 is reduced.
In conjunction with the above, when the capacitor 14 discharges to supply power to the power supply module 13, the terminal may not be within the preset range of the food material management apparatus 10, and the near field communication module 11 does not charge the capacitor 14 through the charging port 111. Moreover, since the capacitor 14 is discharging, the voltage of the first end 141 of the capacitor 14 will gradually decrease, and when the voltage of the first end 141 is lower than the preset value, the power module 13 stops outputting the working voltage through the output port 132. In addition, the control module 12 can continuously refresh the display module 15 during normal operation, and if the power module 13 stops outputting the operating voltage to the control module 12 and the display module 15, the display module 15 may flicker or be interrupted to cause a defect.
Therefore, the capacitor 14 can be discharged through the discharge port 121 after the control module 12 controls the display once, so that the power module 13 stops supplying power to the control module 12 and the display module 15, and further, the display module 15 is prevented from flickering or being interrupted to cause deformity.
Fig. 5 is a schematic structural framework diagram of a food material management device 10 according to still another embodiment of the present application.
Specifically, referring to fig. 5, the food material management apparatus 10 further includes a resistor 16, one end of the resistor 16 is electrically connected to the discharge port 121, the other end of the resistor 16 is electrically connected to the first end 141 of the capacitor 14, and the capacitor 14 discharges through the resistor 16 and the discharge port 121.
Specifically, the resistor 16 and the capacitor 14 form a resistance-capacitance discharge circuit by the arrangement of the resistor 16. When the capacitor 14 is discharged, the capacitor 14 can be rapidly discharged through the rc discharge circuit, so as to rapidly reduce the voltage of the capacitor 14, thereby ensuring that the power module 13 rapidly stops supplying power.
Further, the power module 13 is grounded, and the discharge port 121 is connected to the ground terminal of the power module 13, so that the discharge port 121 discharges through the ground terminal of the power module 13.
Fig. 6 is a schematic structural framework diagram of a food material management device 10 according to still another embodiment of the present application.
With reference to fig. 6, specifically, the food material management apparatus 10 further includes an antenna coil 17, the near field communication module 11 is provided with an antenna port 112, the antenna coil 17 is connected to the antenna port 112, and the near field communication module 11 performs near field communication with a terminal or obtains an induced voltage through the antenna coil 17.
The near field communication module 13 is provided with two antenna ports 112, one end of the antenna coil 17 is electrically connected to one of the antenna ports 112, and the other end of the antenna coil 17 is electrically connected to the other antenna port 112, so that a closed loop is formed between the antenna coil 17 and the near field communication module 11.
In combination with the above, in this embodiment, the antenna coil 17 is used as an induction module and is provided separately from the near field communication module 11, and the near field communication module 11 realizes communication or obtains induction voltage through the separate antenna coil.
Fig. 7 is a flowchart illustrating a control method of a food material management apparatus according to an embodiment of the present disclosure. The method may be based on the food material management apparatus 10 described in any of the above embodiments, and with reference to fig. 7, the method includes the following steps:
s11: and when the charging port is disconnected, acquiring food material management information from the terminal through the near field communication module.
After the food material management information is set in the terminal, the user enables the terminal and the near field communication module to carry out data transmission through approaching the food material management device, so that the near field communication module can acquire the food material management information from the terminal.
When the near field communication module acquires the food material management information from the terminal, the charging port is disconnected, so that the near field communication module cannot charge the capacitor through the charging port, and data transmission is performed between the near field communication module and the terminal.
By the method, the electromagnetic field can not be occupied by acquiring the induction voltage when the near field communication module carries out near field communication, and the stability and the speed of data transmission are improved.
S12: and controlling the charging port to be connected based on the terminal instruction, and charging the capacitor through the charging port.
After the near field communication module acquires the food material management information from the terminal, the terminal further sends a command for connecting the charging port to the near field communication module, and at the moment, the near field communication module controls the charging port to be connected based on the terminal command.
When the charging port is connected, and the distance between the terminal and the food material management device is within the preset distance, the terminal can generate electromagnetic induction with the food material management device, so that the near field communication module can continuously acquire induction voltage, and the capacitor is charged through the output of the charging module.
Fig. 8 is a flowchart illustrating a control method of a food material management apparatus according to another embodiment of the present disclosure. In combination with the above, in some specific embodiments, before step S11, the method further includes the following steps:
s21: and acquiring a user instruction through the near field communication module.
After the near field communication module can perform near field communication with the terminal, and before the near field communication module acquires the food material management information from the terminal, the terminal firstly sends a control instruction to the near field communication module, wherein the control instruction comprises an instruction for disconnecting the charging port.
It should be understood that when the terminal and the near field communication module are capable of near field communication, the charging port may be in an on state, and thus the charging port needs to be turned off.
