Description

A multifunctional classroom roll call management system

technical field

The invention relates to the field of intelligent instruments, in particular to a multifunctional classroom roll call management system.

Background technique

With the continuous popularization of higher education, more and more people are able to enter universities for further studies. Because university teachers generally need to take many classes of students to class, it is impossible to keep in mind the appearance of each student, so roll call before class is a common practice in university classes. In addition, students playing mobile phones in class is also a headache for teachers.

There is a classroom roll call system on the market, but the efficiency and practicability are relatively low. In addition, classroom roll call and mobile phone management are separated in the current market, and there is no unified all-in-one machine with a relatively high degree of automation. At present, there is no perfect classroom roll call system on the market, and classroom roll call systems are relatively rare. Currently there are mobile phone management devices on the market, but they are bulky and immovable.

At present, teachers seldom use the roll call system in class. Basically, they use verbal roll call or sign in. On the one hand, they need to use a lot of class time, and on the other hand, it is impossible to avoid the phenomenon of answering or signing on behalf of others.

The existing classroom roll call and mobile phone management systems are separate, and the efficiency is relatively low.

The existing mobile phone management is mainly in the form of a cloth bag. Students put their mobile phones into the cloth bag before get out of class, and it is easy to be confused when students take it out after class.

Wherein, the main controller includes a time setting module, through which the class time is set; the microprocessor generates the data of the number of people who should arrive according to the quantity of the storage drawer 200, and generates actual data according to the actual sensing data of the pressure sensor 300. The number of people will be received, and the number of people who will be late will be generated according to the class time and the actual sensing data of the pressure sensor 300.

In an optional embodiment of the present invention, the main controller is a programmable single-chip microcomputer.

Optionally, the display screen can be a display screen installed on the classroom wall, or the teacher's own mobile phone, which receives the attendance data sent by the data transmission module via Bluetooth.

Each storage drawer 200 is marked with a number, and students can put their mobile phones in the designated storage drawer 200 according to their student numbers, thereby reducing the possibility of students taking it by mistake or missing it.

Concretely, in conjunction with Fig. 1-3 and shown in Fig. 4, the step of using the multifunctional classroom roll call management system provided by the present invention to carry out roll call includes:

The number of the storage drawer 200 is pre-entered into the memory (such as 1, 2, 3, 4, 5, 6, 7...50), and the class time is set through the time setting module, such as 9:40. When students enter the classroom, they need to put their mobile phones into the corresponding storage drawers 200 according to their individual student numbers. The student who is 02 puts the mobile phone into the storage drawer 200 numbered 2. When the student puts the mobile phone into the storage drawer 200, it can be sensed by the pressure sensor 300 at the bottom of the storage drawer 200, and the sensed data will be transmitted to the microprocessor of the main controller. The microprocessor generates the data of the number of people who should arrive according to the quantity of the storage drawer 200 (that is, the quantity of the storage drawer 200 is the number of people who should arrive), and generates the actual number of people according to the actual sensing data of the pressure sensor 300 (that is, the pressure that generates the data). The number of sensors 300 is the number of actual arrivals), and the number of latecomers is generated according to the class time and the actual sensing data of the pressure sensor 300 (that is, the time when all pressure sensors 300 generate sensing data is later than the number of class time). For example, in one embodiment, a storage box 100 with 50 drawers is provided to carry out the roll call. There are 45 people in the class of the roll call, and 40 people arrive, of which 5 people are late. This data can be displayed on the display screen in real time. The teacher can check the attendance status by watching the display screen.

In addition, considering that in actual situations, students can put other objects into the storage drawer 200 to create the illusion that the mobile phone has been put into the storage drawer 200, so the present invention is provided with an infrared image recognition module in the storage drawer 200 , preferably, the infrared image recognition module is arranged on the inner side of the baffle of the storage drawer 200 . The infrared image recognition module has an infrared lens, which collects the three-dimensional image data of the objects stored in the storage drawer through the infrared lens, and uploads the three-dimensional image data to the cloud server, and the cloud server compares the received three-dimensional image data with the data in the database The data is matched to determine whether the object stored in the storage drawer is a mobile phone. This system adopts cloud intelligent recognition method for image recognition, which makes the recognition effect more accurate. For example, in one embodiment, a storage box 100 with 50 drawers is provided to carry out the roll call. There are 45 people in the class of the roll call, and 40 people arrive, of which 5 are late, and two of the 40 people who actually arrive If the mobile phone is not put into the storage drawer 200, the infrared image recognition module sends the result of abnormal recognition to the display screen for display, which is convenient for the teacher to check.

The ingenious classroom roll call system and the mobile phone management system of the present invention are well combined together, saving time and labor, eliminating the bad phenomenon of students playing with mobile phones, and being conducive to the construction of the style of study. At the same time, this device uses the Bluetooth receiving device to realize real-time feedback on the attendance results, and the degree of automation is relatively high. And through the single-chip microcomputer program control, the function of one-key copying the attendance results can be realized and summarized.

The preferred embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; Under the circumstances of the technical solution of the invention, many possible changes and modifications can be made to the technical solution of the present invention by using the methods and technical contents disclosed above, or be modified into equivalent embodiments with equivalent changes, which does not affect the essence of the present invention .
