Abstract
The invention discloses an indoor harmful gas monitoring system which comprises an MQ2 gas sensitive sensor, a dust sensor, an A/D conversion circuit, a DSP microprocessor and an air inlet end control circuit. The MQ2 gas sensitive sensor and the dust sensor are connected with the signal input end of the DSP microprocessor through the A/D conversion circuit. The signal output end of the DSP microprocessor is connected with the air inlet end control circuit. The air inlet end control circuit comprises an indoor air valve control circuit and an outdoor air valve control circuit. The indoor harmful gas monitoring system is simple, and has the functions of monitoring the concentration of indoor gases in real time, giving out concentration over-standard alarms and automatically starting an air inlet valve.
Description
Technical field
The present invention relates to a kind of monitoring harmful gases system, be specifically related to indoor harmful gas monitoring system.
Background technology
Along with the development of economic society, it is plentiful that people are no longer satisfied with on material, more focuses on the pursuit to quality of life.In order to enjoy family's warmth and visual sensation, often use a large amount of ornament materials during finishing, and these materials release a large amount of dusty gas, as formaldehyde, ammonia, radon etc., serious threat health safety; Newly renovated house, a large amount of dust also can be filled the air in indoor, causes adverse influence to the breathing of human body.Meanwhile, coal gas or natural gas also enter huge numbers of families, and potential danger also enters huge numbers of families.The thing that the anthracemia that gas leak or gas leakage cause has when being; especially cold winter; people habitually shut the cold air that door and window resists outside; once there is gas leak or gas leakage; the healthy and safe of human body will be injured; the probably life of crisis human body, causes huge life and property loss.So, develop a kind of easy monitoring system, the residing indoor gas concentration of people can be informed at any time, concentration over-standard reports to the police and start the indoor harmful gas monitoring system of inlet flap voluntarily, for people have a health, the living environment of safety provides safeguard.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple and easy, has the gas concentration of Real-Time Monitoring indoor, concentration over-standard reports to the police and start the indoor harmful gas monitoring system of inlet flap voluntarily.
Indoor harmful gas monitoring system, comprise MQ2 gas sensor, dust sensor, A/D change-over circuit, DSP microprocessor, inlet end control circuit, described MQ2 gas sensor is connected DSP microprocessor signals input with dust sensor through A/D change-over circuit, DSP microprocessor signals output connects inlet end control circuit, and described inlet end control circuit comprises indoor air-valve control circuit and outdoor air-valve control circuit.
Further, described DSP microprocessor signals input is also connected with keyboard, the setting value of convenient input gas concentration and some other numerical value.
Further, described DSP microprocessor signals output is also connected with display and warning device, and realizing people can other situation such as real time inspection indoor harmful gas content intuitively, is inform indoor personnel by warning device when harmful gas concentration exceeds standard.
Further, described DSP microprocessor also connects host computer by communication interface, makes control more diversified.
Beneficial effect of the present invention is:
The present invention can according to the harmful gas concentration in MQ2 gas sensor and the real-time nernst cell of dust sensor and dust granules concentration, shown by display after DSP microprocessor processes, and make comparisons with harmful gas concentration setting value and dust granules concentration set point, the opening and closing of air-valve and outdoor air-valve in control room voluntarily, ensure that indoor oxygen content maintains desirable level, also inform indoor personnel by warning device when the harmful substances such as indoor harmful gas exceed standard.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of indoor harmful gas monitoring system of the present invention.
Detailed description of the invention
Accompanying drawing discloses concrete structure of the present invention without limitation, and below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, indoor harmful gas monitoring system, comprise MQ2 gas sensor, dust sensor, A/D change-over circuit, DSP microprocessor, inlet end control circuit, described MQ2 gas sensor is connected DSP microprocessor signals input with dust sensor through A/D change-over circuit, DSP microprocessor signals output connects inlet end control circuit, and described inlet end control circuit comprises indoor air-valve control circuit and outdoor air-valve control circuit.Described DSP microprocessor signals input is also connected with keyboard.Described DSP microprocessor signals output is also connected with display and warning device.Described DSP microprocessor also connects host computer by communication interface.
The present invention is by air concentrations such as the pernicious gases in MQ2 gas sensor, the real-time nernst cell of dust sensor, and signal is sent to DSP microprocessor, the analysis of DSP microprocessor processes is shown by display, and compare with the setting value of input through keyboard, if pernicious gas isoconcentration exceeds standard, DSP microprocessor sends control instruction, action made by warning device, inform that indoor occupant is ready, simultaneously, DSP microprocessor also sends control instruction to inlet end control circuit, and what opening chamber's inner blower was conducive to indoor harmful gas is discharged into outside room; If pernicious gas isoconcentration does not exceed standard, DSP microprocessor sends control instruction to inlet end control circuit, opens the circulation that outdoor fan is conducive to indoor-outdoor air.Administrative staff also control whole system by host computer real time inspection.
