By intuitively displaying the current state of the classroom, the query personnel can easily select a suitable classroom for different purposes. Brief Description of the Drawings

[0012] Figure 1 It is the overall flowchart of the real-time query method for idle classrooms in the embodiment of the present invention. Detailed Embodiment

[0013] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0014] A real-time query system for idle classrooms based on a single-chip microcomputer includes a single-chip microcomputer AT89C52, a classroom status display module, a real-time clock module, a key query module. In addition, in order to monitor data, a serial port monitoring module is also included.

[0015] The classroom status display module uses a liquid crystal display screen (touch control enabled), and includes a key query module and an information display module; the information display module is specifically used for displaying the following information: the current query time, the number of busy and idle classrooms, the names of idle classrooms, the class schedules of idle classrooms on the current day, the locations of idle classrooms, and the navigation to the locations of idle classrooms; the key query module includes query function keys and navigation keys; users can query the busy and idle status of classrooms in the teaching building by clicking the query function keys on the touch liquid crystal display screen; when the user clicks the navigation key of the target idle classroom, the optimal path information from the current location to the target classroom is displayed on the liquid crystal display screen, saving the arrival time.

[0016] The serial port monitoring module is a monitoring device installed inside the classroom; the real-time clock module includes a clock system and an information storage system. The clock system is used to determine the time, and the information storage system stores the images and videos of the classroom usage status collected in real time by the serial port monitoring module.

[0017] The single-chip microcomputer AT89C52 determines the busy or idle situation of the classroom by calling the stored images and videos of the classroom usage status; specifically, it randomly calls the images and videos of the classroom usage status stored at the user's query time, analyzes and discriminates the data of the number of students assigned to each classroom and the noise intensity data present in the classroom, obtains the usage situations of different classrooms, and the single-chip microcomputer AT89C52 returns the determined classroom status to the classroom status display module, and the current query time, the number of busy and idle classrooms, the names of idle classrooms, the class schedules of idle classrooms on the current day, the locations of idle classrooms, and the navigation to the locations of idle classrooms are displayed through the liquid crystal display screen.

[0018] The analysis and discrimination specifically include image recognition and noise recognition; the image recognition is specifically as follows: identify the seats in the classroom usage status image, and when the number of vacant seats exceeds the set proportion of all seats in the classroom, which is set to 80% in this embodiment, it is determined to be in an idle state; the noise recognition is specifically as follows: discriminate the signal-to-noise ratio in the classroom usage status video, and when the noise is lower than the set threshold, it is determined to be in an idle state.

[0019] The classroom status display module controls the display of the busy and idle status of each classroom and the keyboard key control through the single-chip microcomputer AT89C52.

[0020] The data also includes querying the time, and obtaining the status information of the classroom at the corresponding time through the query of the time; the effective combination of the information storage system and the clock system makes the system work more accurately and have higher real-time performance.

[0021] In this embodiment, C language is used for programming. C language instructions execute relatively fast and occupy less memory. At the same time, in order to facilitate the expansion and modification of the system functions, each function of the system is divided into small pieces in this design, and a modular structure is adopted to design the logical relationship of the program design, and different functions are set for calling respectively.

[0022] In this embodiment, as Figure 1 shown, the real-time query system for idle classrooms adopts a one-key query method. By clicking the query function button on the touch display screen, the busy and idle status of the classrooms in the teaching building can be queried. By calling the query function, several factors affecting the idle and busy status of the classrooms are randomly called and analyzed to obtain the real-time status of the classrooms (in this design, the number of students in the classroom and the noise intensity are considered as two factors). Finally, information such as time information and the number of idle classrooms is returned to the liquid crystal display for display, and students can intuitively see the currently queried information, which is convenient for them to select the use of classrooms.

[0023] In this embodiment, the information storage system aims to achieve the effective storage and data retrieval of the information of each classroom, and realizes the functions of information storage and retrieval query through programming. As the core of the research, the information storage and call system completes the tasks of data storage and query by processing the information storage, data call and programming writing of each classroom in the teaching building. This system details the basic concepts and operation steps of information storage, information display, clock setting and data random allocation.

[0024] Using the DS1302 clock system, we can accurately time time information such as year, month, day, week, hour, minute and second. The main functions of this system include querying the idle or busy status of each classroom at the current time, randomly calling data from the information storage for comparative analysis to judge the use situation of the classrooms, and displaying the required information, so as to facilitate students to select suitable classrooms.
