Description
Technical Field
The invention relates to a green intelligent lighting system.
Background
The energy source is a foundation stone existing and developing in the modern society. With the continuous development of global economic science and technology, the energy consumption is correspondingly and continuously increased, and the fossil energy is sharply reduced and simultaneously causes great pollution to the environment. In response to this situation, society has begun to pay attention to green energy sources represented by solar energy. The characteristics of safety, high efficiency, no pollution and reproducibility of solar energy, and the gradual maturity of the existing photovoltaic technology, the utilization of photovoltaic power generation becomes a great way to solve the energy problem.
The lighting of corridor lamp example belongs to the public facilities, the installation maintenance management is shared by owners and property in principle, the present corridor lamp charge includes two parts, one part is the maintenance charge, the other part is the electricity charge, but in practice, the corridor lamp charge is different and has no uniform standard, so that the contradiction between owners and property management departments is sharp. Still many corridor lights are still illuminated overnight with light bulbs and old switches, and the corridor lights are now being changed to LED lighting. The solid-state lighting lamp using the light-emitting diode LED as the light source consumes 1/8 power of a common incandescent lamp, and the service life of the solid-state lighting lamp is 10 times longer than that of the common incandescent lamp.
At present, the traditional corridor lamp is controlled by matching two modes of voice control and touch control with light control (the lamp is not on in the daytime). Both of these approaches can achieve energy saving to some extent, but there is still room for improvement. Among them, the voice control method has obvious disadvantages. For example, in a thunderstorm or in a windy weather, the corridor lights are often turned on because the sound control lights cannot accurately judge whether the sounds are artificially generated. Touch lamps sometimes have inconvenience, for example, when people carry full things with hands through a corridor, people need to put down the objects in the hands when trying to turn on the lamps, and some inconvenience is caused. The project adopts the pyroelectric infrared technology to control the on and off of the lamp.
In nature, any object above the absolute temperature (-273K) will produce an infrared spectrum, and the infrared energy emitted by objects at different temperatures will have different wavelengths, so that the infrared wavelength is related to the temperature, and the amount of radiated energy is related to the surface temperature of the object. The human body has constant body temperature, generally at about 37 ℃, infrared rays with specific wavelength of about 10 mu m can be emitted, the infrared probe can detect the infrared rays emitted by the human body, the lamps are controlled to be on through a series of devices to output signals, and then the lamps are controlled to be off through a time delay device, so that the effects of lighting when a person comes and lighting when a person walks are achieved. The light and the fire of the lamp are controlled by the pyroelectric infrared technology, so that the lamp is more convenient and intelligent, and the condition of misjudgment is less than that of a voice-operated switch.

The single chip microcomputer has no reset function, so that the reset operation can be realized only by combining the single chip microcomputer and an external circuit. When the reset signal is at high level, the machine needs to sample once through the reset circuit every period, and if the reset end continues to be at high level for more than two periods, the singlechip is reset. At the moment of power-on, the circuit is charged, and then the reset section generates positive pulse to reset the single chip microcomputer. A reset signal of an STC89 series single chip microcomputer based on an 8051 core is input into a Schmitt trigger of the chip from a RST pin. When the system is in normal operation and the oscillator is stable, the CPU can respond and reset the system if the RST pin has a high level and is held for 2 machine cycles (24 oscillation cycles). Manual push-button reset requires a human to put a high level on the reset input RST. The common approach is to connect a button between the RST terminal and the positive power supply Vcc. When the button is manually pressed, the +5V level of Vcc is directly added to the RST terminal. The time requirement for resetting can be fully met because the button can be kept on for tens of milliseconds even if the action of a person is fast.
