An Internet of Things system for indoor light temperature control

Abstract

The invention provides an Internet-of-things system for controlling the indoor light illumination temperature. The Internet-of-things system for controlling the indoor light illumination temperature comprises a temperature sensor, a photosensitive sensor, an A / D conversion module, a single-chip microcomputer, a motor, a serial port, a wifi module and an upper PC, wherein the temperature sensor is used for collecting the indoor temperature, the photosensitive sensor is made of a photosensitive resistor with the resistance value rapidly decreased under light illumination and is used for collecting indoor light rays, and the A / D conversion module is used for conducting analog-digital conversion on the output voltage value. The temperature sensor sends digital temperature signals to the single-chip microcomputer. After the analog-digital conversion is conducted on the resistance value change generated by the light rays through the A / D conversion module, the resistance value change is sent to the single-chip microcomputer through the photosensitive sensor. The single-chip microcomputer converts the resistance value change to high and low electric levels corresponding to pins according to the received signal, and the high and low electric levels are sent to the upper PC through the serial port by means of the wi-fi module to be displayed and stored. The upper PC obtains light illumination data and temperature data according to real-time measurement, conducts control optimization through a discrete particle swarm algorithm, and returns control instructions to control the motor to work in real time. The Internet-of-things system for controlling the indoor light illumination temperature is high in search speed and efficiency and simple in algorithm.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to an Internet of Things system for indoor lighting temperature control. Background technique [0002] The reason for indoor light temperature control is that the indoor light conditions are mainly natural light, but the utilization rate is only 40% to 60% of the open environment. Therefore, the effective utilization of light should be improved as much as possible. According to the indoor temperature and illuminance collected in real time, the curtain motor control system can be used to adjust the indoor temperature to the maximum extent. [0003] The Internet of Things is an important part of the new generation of information technology. It uses communication technologies such as local networks or the Internet to connect sensors, controllers, machines, people, and things together in new ways to form a connection between people and things, and between thi...
