Background

The number of teachers in China exceeds 1000 thousands, and 105 thousands of teachers in common colleges and adults basically meet the requirement of education career in China. On this basis, there are a large number of new teachers who keep the staff replaced each year, and at the same time, there is still room for further improvement in teaching ability, teaching level and teaching design for young teachers at work.

In the daily teaching process, factors such as time, content arrangement, abnormity and the like occur from time to time, so that the teaching design cannot be implemented in place, and the expected effect cannot be achieved. Further investigation finds that most of excellent teachers need long periods to accumulate teaching experience and cultivate teaching skills, so that teaching evaluation falls out of the seniors, and the phenomenon obviously comes in and goes out with the education law. Most of the confusion of the newly-entered teachers in the teaching process is mainly found in the control of time. In the teaching process, the links of the original teaching design are increased, decreased or avoided due to factors such as tension, excitement or difficulty and the like, so that the phenomena of losing confidence of a card shell, incapability of understanding by a super student, avoidance of switch key knowledge points or dissatisfaction of the student due to repeated explanation and the like occur in the teaching process.

In order to solve the problems, the application provides an auxiliary supervising system for classroom teaching.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-2, the classroom teaching auxiliary supervising system provided by the utility model comprises a housing 1, wherein a display screen 2 is arranged inside the housing 1;

an adding key 3, a subtracting key 4, a direction key 5, a power switch key 6, a NEXT key 7, a starting key 8, a clearing key 9 and a charging interface 10 are arranged on the shell 1;

a circuit board 15 is fixedly installed on the back of the display screen 2, and a clock chip 11, a Bluetooth communication module 12 and a control chip 14 are installed on the circuit board 15;

a rechargeable lithium battery 13 is mounted in the case 1 and connected to the circuit board 15;

the add button 3, the subtract button 4, the direction button 5, the power switch button 6, the NEXT button 7, the start button 8, the clear button 9 and the charging interface 10 are all connected with the circuit board 15.

In an alternative embodiment, the clock chip 11 is a DS1302 clock chip.

In an alternative embodiment, the control chip 14 is an STM32 control chip.

In an alternative embodiment, the display screen 2 is a 7-inch RGB display screen and is mounted inside the housing 1 by screws.

In an alternative embodiment, the bluetooth communication module 12 is communicatively coupled to a cellular phone.

It should be noted that, after the power is turned on, the clock chip 11 and the clock circuit provide information of second, minute, hour, day, date, month and year in real time, the number of days per month and the number of days in leap year can be automatically adjusted, the serial interface is used for communicating with the control chip 14, the data is transmitted to the control chip 14, the control chip 14 receives data generated by pressing a key by a user and controlling the whole system through the bluetooth communication module 12, the data is processed through a program compiled and written into the control chip 14, the 24-bit RGB interface is connected for communication with the display screen 2, and the data is transmitted to the display screen 2, so that the functions of various timing, flashing and time display can be realized.
