Embodiment Construction

[0024] Further description will be made below in conjunction with drawings and embodiments.

[0025] The hardware composition of the car air purification system is as follows: figure 1 As shown, the system is mainly composed of AT89C51 single-chip microcomputer and its peripheral circuit, smoke concentration sensor, air purification device, external control switch and other components. Low-voltage, high-performance CMOS 8-bit microprocessor, compatible with the industry standard MCS-51 microcontroller instruction set and output pins, AT89C51 microcontroller provides a flexible and inexpensive solution for many embedded systems. In the system, it mainly receives various information from the detection input of the smoke concentration sensor, and performs corresponding processing to control the operation of the car air purification device; The concentration signal is converted into a voltage signal, which is input to the single-chip microcomputer AT89C51 through signal amplifica...

Abstract

The invention relates to a car air purifying system. According to the car air purifying system under the control of a singlechip AT89C51, smoke particles can be automatically detected through a smoke consistency sensor, so that the running of an air purifier can be controlled. The system comprises a control unit, the smoke consistency sensor and a car air purifier, wherein the singlechip AT89C51 is adopted in the system to receive various information detected and input by the smoke consistency sensor and carry out corresponding treatment, thus controlling the running of the car air purifier; the smoke consistency sensor is used for sensing whether the smoke particles exist in a carriage of a car, and transforming the sensed smoke consistency signals into voltage signals; the voltage signals pass through a signal amplifying circuit and other processing circuits, and then are transmitted into the singlechip AT89C51, so that the running of the air purifier is controlled to keep the air in the carriage clean; and the car air purifier is primarily structured through an air blowing motor, a filter, an air adjusting door of an air blower, a housing, and the like.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to an automobile air purification system controlled by a single-chip microcomputer AT89C51. Background technique [0002] With the acceleration of the electronic process of automobiles, higher requirements are put forward for the comfort, safety and environmental protection of automobiles. In the car compartment, the air pollution inside the car is caused by passengers smoking or invading dust from outside the car, which will seriously endanger human health. Designing an automatic air cleaning system for this reason seems necessary to meet people's requirements for high-quality automobile performance. The air purification device that is widely used in automobiles is a part of the automobile air conditioning system, and only high-end cars have it, and ordinary cars do not have air purification devices. Therefore, an automatic air purification system that is simple, prac...
