Description

Intelligent Control System of Classroom Power Supply Based on Semester Class Schedule

technical field

The utility model relates to an intelligent control system of a classroom power supply based on a semester schedule.

Background technique

At present, there is a large waste of electricity in the operation of classroom lighting, multimedia consoles and other related equipment in colleges and universities. Because these colleges have the characteristics of large area, many classrooms and complicated learning locations, colleges and universities Large electricity consumption and difficult management of electrical appliances have forced the management to install electrical switches in classrooms to facilitate teachers and students to turn off electrical appliances. However, due to different class hours or study time, electrical appliances are often turned off randomly. After being opened, it cannot be closed in time, resulting in a large amount of waste of electric energy, which is closely related to the extensive management of electric energy consumption of teaching facilities. How to refine the electric energy of colleges and universities without increasing the difficulty of property management Management, reducing power consumption and waste, there is no relevant practical technical solution yet.

Contents of the invention

The purpose of the utility model is to provide an intelligent control system of classroom power supply based on the semester schedule, which has the advantages of simple and convenient control, high reliability, energy saving and environmental protection.

The utility model is realized in this way, it comprises single-chip microcomputer, pyro-release infrared sensor module, clock module, reset circuit module, clock display module, keyboard array module, drive module, solid state relay module and power switch, it is characterized in that single-chip microcomputer and The pyro-infrared sensor module, the clock module, the reset circuit module, the clock display module, the keyboard array module are connected with the drive module, and the drive module is connected with the power switch through the solid state relay module.

The technical effects of the utility model are: the utility model designs an intelligent control system for classroom multi-channel power supplies based on timetables in view of the current operating status of classroom lighting, multimedia consoles and other related equipment and the phenomenon of massive waste of electricity. The system uses a single-chip microcomputer as the intelligent component of the control device, and uses a pyro-infrared sensor to detect the existence of the human body; according to the classroom schedule of this semester, with the help of the electronic clock configured for the classroom by this system, the intelligent control of the power supply of each electrical equipment in the classroom is completed. , avoiding a lot of waste of electricity in the classroom and difficult management. The system has the advantages of small size, convenient control, high reliability, strong specificity, and reasonable cost performance. It can meet the requirements of power control for classroom equipment in various large and technical secondary schools, and achieve the purpose of energy saving and staff reduction to a large extent.

Detailed ways

As shown in Figure 1, the utility model is realized in this way, and it comprises single-chip microcomputer, pyrolysis infrared sensor module, clock module, reset circuit module, clock display module, keyboard array module, drive module, solid-state relay module and power switch, Its structural feature is that the single-chip microcomputer is respectively connected with the pyro-infrared sensor module, the clock module, the reset circuit module, the clock display module, the keyboard array module and the drive module, and the drive module is connected with the power switch through the solid state relay module.

The work process of the present utility model is such that according to the semester schedule, the schedule data is input to the single-chip microcomputer through the keyboard array module, and the clock module counts the schedule time data, and displays it at the clock display module. Drive the solid-state relay module and control the power switch through the solid-state relay module. When people randomly enter the classroom, the pyro-infrared sensor module senses the heat-sensitive signal of the person entering and sends it to the single-chip microcomputer. The single-chip microcomputer makes a judgment of temporarily turning on the power switch. If you need to change the settings in the microcontroller, you can reset the clock data through the reset circuit module and reset the clock.
