It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more.

[0039] Please refer to Figure 1 , Figure 1 is a structural block diagram of the answerer 100 provided by some embodiments of the present application.

[0040] The embodiments of the present application provide an answerer 100, which comprises a power supply module 10, a control module 20, a storage module 30, a display module 40, a key module 50 and a communication module 60.

[0041] The control module 20 is connected with the storage module 30, the display module 40, the key module 50 and the power supply module 10 respectively, and the power supply module 10 is also connected with the storage module 30, the display module 40 and the key module 50 respectively.

[0042] Specifically, the power supply module 10 is configured to be connected with the first power supply 200 and / or the battery 300, obtain electric energy from the first power supply 200 to charge the battery 300, and obtain electric energy from the battery 300 to supply power to the control module 20, the storage module 30, the display module 40 and the key module 50.

[0043] The storage module 30 is configured to store data.

[0044] The display module 40 is configured to receive data input by the control module 20 and display information in the data input by the control module 20.

[0045] The key module 50 is configured to receive operation data input by a user.

[0046] The communication module 60 is configured to perform wireless communication with the receiving end device 400 to establish a binding relationship with the receiving end device 400.

[0047] The control module 20 is configured to receive operation data through the key module 50, send the operation data to the receiving end device 400, receive feedback data sent by the receiving end device 400, and send the feedback data to the display module 40 to enable the display module 40 to display information in the feedback data.

[0048] The first power source 200 is a power source of the answerer 100. It can be a power source in various forms, such as an alternating current power adapter that converts mains (usually 220V alternating current) into lower voltage direct current suitable for charging the answerer 100, or a USB interface connected power source, such as a connection to a computer USB interface to obtain 5V direct current. The main function is to charge the battery 300 in the answerer 100, to ensure that the battery has enough power to power the various modules of the answerer. For example, in a school classroom, if the answerer 100 is low in power, the student can connect the answerer 100 to the USB interface of the classroom computer through the charging line (at this time the USB interface of the computer serves as the first power source 200), so that the battery of the answerer can be charged while the answerer is being used, so that the answerer can continue to work normally.

[0049] The battery 300 is mainly used for power storage, and is usually a rechargeable battery such as a lithium battery. Its main role is to store electrical energy, and when the answerer 100 is not connected to the first power source 200 or the first power source 200 cannot provide power, it provides the required electrical energy for the operation of the control module 20, the storage module 30, the display module 40 and other key modules of the answerer, to ensure that the answerer can work independently and normally. For example, when a student takes the answerer 100 to a place without a power outlet for an exam, the battery 300 plays a role, as it can provide enough power for the answerer, so that the student can operate the answerer through the key module 50, view the questions and feedback information through the display module 40, and so on.

[0050] The receiving end device 400 is an external device that communicates with the answerer 100, receives the operation data sent by the answerer 100, processes the data, and then sends the processed feedback data to the answerer. It can be various types of devices, such as a server in an examination system, a teaching management terminal for teachers, etc. Its main function is to serve as a data processing center, to perform corresponding operations (such as grading, counting the progress of answering, etc.) according to the operation data (such as the answering situation of students) sent by the answerer, and to feed back the results to the answerer. For example, in the context of an examination in a school, the receiving end device 400 can be a classroom server installed with examination management software. After a student selects an answer through the answerer 100, operation data (including the student's answering information) is obtained, which is sent to the server. The server judges the answer and determines whether it is correct, and then sends feedback data to the answerer indicating whether the answer is correct, so that the student can see his / her answering situation on the display module 40 of the answerer.

[0051] The operation data is the content input by the user through the key module 50 of the answerer 100. These contents are data related to the user's operations on the functions of the answerer. For example, in the context of answering, the user presses the number keys on the answerer to select answer options, or presses the function keys to submit answers, go to the next question, etc. The information corresponding to these key actions (such as the selected answer number, submission instructions, etc.) is the operation data. After being received by the key module 50, these data are transmitted to the control module 20 for further processing, such as sending the answers to the receiving end device 400 for grading, etc.

[0052] The binding relationship refers to an association established between the communication module 60 of the answerer 100 and the receiving end device 400. Through this association, the answerer 100 can stably and specifically communicate with the receiving end device 400. For example, in an examination system in a classroom, the receiving end device 400 can be an examination management device used by a teacher. When the answerer 100 is turned on, the communication module 60 communicates with the receiving end device 400 wirelessly, and through a series of authentication and configuration steps (such as inputting a pairing code, device scanning, etc.), the answerer 100 and this specific receiving end device 400 establish an exclusive relationship. In this way, the operation data sent by the answerer 100 can be accurately sent to the receiving end device 400 to which it is bound, and the feedback data sent by the receiving end device 400 can also be correctly returned to the answerer 100, avoiding the situation that the data is sent to other irrelevant devices or that the communication is chaotic.

[0053] The feedback data is the data sent by the receiving end device 400 to the answerer 100. These data are the result-related data generated by the receiving end device 400 after processing the operation data sent by the answerer 100. For example, if the answerer 100 sends the answer selected by the user as the operation data, the receiving end device 400 (such as an examination server) will send the grading result (such as correct or incorrect, score, etc.) to the answerer 100 after grading the answer. After the control module 20 receives these feedback data, it will send them to the display module 40, and then the display module 40 can display the information in the feedback data (such as “the answer is correct” or “the answer is incorrect, the correct answer is XX”, etc.) to let the user know the result of the operation.

[0054] In actual application, the answerer 100 can be connected to the first power source 200 (such as a USB interface power source or a power adapter) through the power supply module 10, at which time the power supply module 10 will obtain electrical energy from the first power source 200 and use this part of electrical energy to charge the battery 300. When there is no first power source 200 connected or the first power source 200 cannot supply power, if the battery 300 connected by the power supply module 10 has electricity, the power supply module 10 can obtain electrical energy from the battery 300 to provide power for the control module 20, the storage module 30, the display module 40, the key module 50, etc. to ensure that these modules can work normally.

[0055] The user inputs the operation data through the key module 50. For example, in the answer scenario, the user presses the keys to select the answer, start answering, submit the answer, etc. The key module 50 will receive the signals corresponding to these operations and convert them into operation data, and then send the operation data to the control module 20.

[0056] After receiving the operation data, the control module 20 will send it to the receiving end device 400. Before that, the communication module 60 can establish a binding relationship with the receiving end device 400 in advance, which is like establishing a dedicated channel for data transmission to ensure that the operation data can be accurately sent to the corresponding receiving end device 400.

[0057] After receiving the operation data, the receiving end device 400 will process these data. Taking the examination answering as an example, the receiving end device 400 can grade according to the operation data (answer), or record the answering progress, etc. Then, the receiving end device 400 will send the feedback data (such as whether the answer is correct, the score, the next question content, etc.) to the answerer 100 after processing.

[0058] After the control module 20 of the answerer 100 receives the feedback data, it sends the feedback data to the display module 40. After the display module 40 receives the feedback data, it extracts and displays the information in the feedback data, such as displaying "correct answer" "score: 5 points" or the content of the next question on the screen, so that the user can intuitively see the result of the operation or the subsequent task.

[0059] During the entire process, the control module 20 can store operation data, feedback data, etc. in the storage module 30 as needed. For example, store the user's answer record, score history, etc. The stored data can be used for subsequent query, statistics, etc. functions, such as viewing historical answer conditions or analyzing learning progress.

[0060] Please refer to Figure 2 , Figure 2 is a structural block diagram of the power supply module 10 provided by some embodiments of the present application.

[0061] In some embodiments, the power supply module 10 includes a power supply interface 11, a charging unit 12, a battery interface 13, and a voltage stabilizing unit 14. The power supply interface 11 is connected to the charging unit 12, the charging unit 12 is also connected to the battery interface 13, the battery interface 13 is also connected to the voltage stabilizing unit 14, and the voltage stabilizing unit 14 is also connected to the control module 20, the storage module 30, the display module 40, and the key module 50.

[0062] Specifically, the power supply interface 11 is used to connect with the first power source 200. The battery interface 13 is used to connect with the battery 300. The charging unit 12 is used to process the first voltage input by the first power source 200 to obtain a charging voltage, thereby charging the battery 300. The voltage stabilizing unit 14 is used to process the discharge voltage of the battery 300 to supply power to the control module 20, the storage module 30, the display module 40, and the key module 50.

[0063] In actual application, first, the first power source 200 (such as an external power adapter or a USB interface power source) is connected to the power supply module 10 through the power supply interface 11. This interface plays a role in physical connection and preliminary electrical connection, ensuring that the power source can be smoothly connected to the subsequent charging unit 12.

[0064] The first voltage provided by the first power source 200 cannot be directly used to charge the battery 300. The charging unit 12 starts to work, which mainly performs a series of processing on the first voltage. This may include voltage reduction (if the first voltage is higher than the charging voltage required by the battery 300), current limiting (if the current is higher than the charging current required by the battery 300), etc. Through these operations, the charging unit 12 converts the first voltage into a charging voltage suitable for charging the battery 300.

[0065] The charging voltage processed by the charging unit 12 is transmitted to the battery 300 through the battery interface 13.

[0066] When the answerer 100 is not connected to the first power supply 200 or the first power supply 200 cannot supply power normally, the battery 300 starts discharging.

[0067] The voltage discharged by the battery 300 is processed by the voltage stabilizing unit 14. It realizes this function through the internal voltage stabilizing circuit. If it is a linear voltage stabilizing circuit, it will stabilize the output voltage by adjusting the conduction degree of the internal transistor according to the difference between the output voltage and the reference voltage; if it is a switching voltage stabilizing circuit, it will convert the battery voltage into a stable output voltage through high-frequency switching action. For example, the voltage discharged by the battery 300 fluctuates between 3.7V-4.2V, and the voltage stabilizing unit 14 can stabilize it at a fixed value, such as 3.3V, which can meet the working requirements of the internal modules such as the control module 20, the storage module 30, and the display module 40.

[0068] In some embodiments, the power supply module 10 further comprises a power-on delay unit 15, wherein the power-on delay unit 15 is connected with the power supply interface 11 and the charging unit 12 respectively.

[0069] Specifically, the power-on delay unit 15 is used to turn on after the power supply interface 11 is connected with the first power supply 200, so as to connect the path between the power supply interface 11 and the charging unit 12.

[0070] In actual application, when the first power supply is connected with the power supply interface 11 (i.e. at power-on), the power-on delay unit 15 does not immediately turn on the path between the power supply interface 11 and the charging unit 12. It starts a delay process according to the internal circuit design (usually based on capacitor charging, timer or other delay circuit elements). This delay time can be set according to the specific circuit parameters and design requirements, for example, several milliseconds to several seconds.

[0071] During the delay process, the capacitor in the circuit may gradually charge, or the timer is counting. Taking capacitor charging as an example, when the power supply is connected, the current charges the capacitor through a resistor, and the voltage across the capacitor gradually rises during the charging process. When the capacitor voltage reaches a certain threshold, the subsequent switching circuit or logic circuit is triggered, so that the path between the power supply interface 11 and the charging unit 12 is completely turned on.

[0072] Please refer to Figure 3 , Figure 3 is a structural schematic diagram of the control module 20 provided by some embodiments of the present application.

[0073] In some embodiments, the control module 20 comprises a master chip U1, a resistor R14 and a resistor R15.

[0074] The 3rd pin (VBAT pin) of the master chip U1 is connected with the power supply module, and the 26th pin (GPIO23 / TP7 pin) of the master chip U1 is connected with the storage module 30 and the display module 40 through the resistor R14. The 18th pin (GPIO4 / BOOT pin) of the master chip U1, the 24th pin (GPIO21 / TP5 pin) of the master chip U1, and the 25th pin (GPIO22 / TP6 pin) of the master chip U1 are all connected with the storage module 30.

[0106] In some embodiments, the answerer 100 further includes the charging detection module and the battery power acquisition module.

[0107] The charging detection module includes a resistor R25 and a resistor R28. The first end of the resistor R25 is connected with the power supply module 10. The second end of the resistor R25 is connected with the first end of the resistor R28. The second end of the resistor R28 is grounded. The second end of the resistor R25 is used to output a charging detection signal.

[0108] Specifically, the battery power acquisition module includes a resistor R24, a resistor R27 and a capacitor C28. The first end of the resistor R24 is connected with the power supply module 10. The second end of the resistor R24 is connected with the first end of the resistor R27, the first end of the capacitor C28 and the control module 20 respectively. The second end of the resistor R27 is connected with the second end of the capacitor C28 and grounded. The second end of the resistor R24 is used to output a battery power acquisition signal.

[0109] The resistor R25 and the resistor R28 constitute a voltage division circuit. When the answerer 100 is in a charging state, the power supply module 10 has a charging current passing through. Since one end of the resistor R25 is connected with the power supply module 10, the charging current will generate a voltage drop when passing through the resistor R25. According to the voltage division principle, the resistance ratio of the resistor R25 and the resistor R28 determines the voltage value of the second end (i.e. the output end) of the resistor R25. This voltage value is the charging detection signal. The charging detection signal is mainly used to detect whether the answerer is being charged. The control module 20 can determine whether the charging process is in progress by detecting the level (voltage) state of the charging detection signal. For example, if the voltage of the second end of the resistor R25 is higher than a certain threshold voltage, the control module 20 can determine that the answerer is being charged; otherwise, if the voltage is lower than the threshold, it is considered that the answerer is not being charged.

[0110] The resistor R24, the resistor R27 and the capacitor C28 constitute a circuit for battery power acquisition. The resistor R24 and the resistor R27 are in a voltage division relationship. The capacitor C28 functions as a filter. The output voltage of the battery is connected to the first end of the resistor R24. When the battery is discharging, the battery voltage is divided by the resistors R24 and R27, and a voltage signal related to the battery power is generated at the second end of the resistor R24. After the signal is filtered by the capacitor C28 to remove high-frequency noise, the battery power acquisition signal is formed. The battery power acquisition signal is used to provide the control module 20 with information about the battery power. The control module 20 can estimate the remaining battery power according to the voltage of the signal.
