Description

Technical Field

[0001] This utility model relates to the field of teaching aids technology, specifically a remotely controllable wireless answer receiver. Background Technology

[0002] Patent CN201922296457.2 discloses a novel wireless quiz terminal transceiver. The transceiver has an antenna on its side and a bottom cover. Between the transceiver and the bottom cover are internally located a microcontroller unit, a power supply unit, a signal output extension unit, a printer control unit, a wireless receiving unit, and a button operation unit. The main viewing surface of the transceiver houses a printer unit and a touchscreen component unit. This invention makes the transceiver operable, while also providing printing functionality and sound prompts, reducing the limitations of wireless quiz systems.

[0003] The existing technical solutions have the following drawbacks:

[0004] The aforementioned transceiver requires the multimedia equipment in the corresponding classroom to open the software to receive answers. This restricts the time and location of the person receiving the answers. Furthermore, after answering the questions, the person must stop receiving answers in the corresponding classroom, which reduces efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a remotely controllable wireless answer receiver to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A remotely controllable wireless answer receiver includes a wireless answer receiver equipped with a central processing unit (CPU). The CPU is connected to a USB interface via a USB bus, and to a WIFI module via a serial bus. The WIFI module is connected to a server. The CPU is connected to a baseband chip via an SPI bus, and the baseband chip is connected to a 2.4G communication antenna. The CPU is also connected to a signal indicator light via a GPIO interface.

[0007] The central processing unit is an APM32F103CBT6 model.

[0008] The server uses the MQTT protocol for communication.

[0009] The baseband chip used is the CI24R1 chip.

[0010] The WIFI module adopts the AI-WB2-12F mode.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: A WIFI module is added to the existing signal transceiver. The WIFI module uses the MQTT protocol to connect to the server and can perform WiFi communication. The USB interface can also perform USB communication. Teachers can remotely control the classroom where answers are recorded through a mobile phone program / feedback system program. After the question is answered, the wireless answer receiver stops receiving after the teacher controls it again through the mobile phone program / feedback system program. Teachers can complete this operation from anywhere, which is convenient for students to answer questions and for teachers to receive answers. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] A remotely controllable wireless answer receiver includes a wireless answer receiver equipped with a central processing unit (CPU). The CPU is connected to a USB interface via a USB bus, and to a WIFI module via a serial bus. The WIFI module is connected to a server. The CPU is connected to a baseband chip via an SPI bus, and the baseband chip is connected to a 2.4G communication antenna. The CPU is also connected to a signal indicator light via a GPIO interface.

[0017] The central processing unit is an APM32F103CBT6 model.

[0018] The server uses the MQTT protocol for communication.

[0019] The baseband chip used is the CI24R1 chip.

[0020] The WIFI module adopts the AI-WB2-12F mode. Example 1

[0021] The teacher sends a control command (start) to the server using a mobile app / feedback system. The server then transmits the command to the receiver via Wi-Fi or USB. The receiver publishes the questions and standard answers and receives the students' uploaded answer data. The answer data is received and entered via a 2.4G communication antenna. After the students finish answering the questions, the teacher sends a control command (stop) to the server using the mobile app / feedback system. The server then transmits the command to the receiver, which stops receiving answer data.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
