Abstract
The utility model relates to an indoor air real-time monitoring and warning alarm, which is internally provided with a temperature and moisture sensor, a dust sensor, a volatile organic pollutant sensor, a formaldehyde sensor, a carbon dioxide sensor and the like; all the sensors pass through a signal acquisition amplifying circuit and then are connected with a multipath high-precision A/D circuit together, the output end of which is connected with a central processor; and the output of the central processor is connected with a display alarming control circuit which has three paths of output, namely a display, an LED lamp and an alarm. The indoor air real-time monitoring and warning alarm can automatically recognize whether the quality of indoor air meets the requirements of ecological household, can continuously monitor the quality of indoor air to reminding a user of taking measures, reducing the indoor air pollution and improving the quality of living.
Description
Technical field
The utility model relates to a kind of air detection device, specifically a kind of room air real-time monitoring and alarming.
Background technology
Along with improving constantly of living standard and quality of life, people more and more pay attention to the living environment of oneself, the ecological household theory of " comfortable, healthy, efficient, attractive in appearance " has become pursuing one's goal of people, and especially Jian Kang living environment has obtained people and more and more paid close attention to.IAQ (indoor air quality) is an important indicator of healthy living environment.Mostly be single special detection device at room air monitoring and the product of reporting to the police at present, can only monitor the air index of certain individual event, and when this index surpasses critical value, report to the police.This monitoring device can not make the user have one comprehensively to understand to the room or the air quality in the office space at its place, can not remind the user to go how to operate and could improve indoor air ambient at indoor actual air situation.In addition, the special-purpose monitoring device of this class has also that sensitivity is low, complicated operation or defective such as cost an arm and a leg, and not too is fit to popular family and uses.
The utility model content
The purpose of this utility model just provides a kind of room air real-time monitoring and alarming, to satisfy the use needs that people require to improve living environment.
The utility model is achieved in that a kind of room air real-time monitoring and alarming, warm and humid sensor is housed in device, dust sensor, the volatile organic contaminant sensor, formaldehyde sensor and carbon dioxide sensor etc., each sensor is respectively by being connected to the input end of duplex high precision A/D circuit altogether behind one tunnel the signals collecting amplifying circuit separately, the output termination central processing unit of duplex high precision A/D circuit, the output of central processing unit connects the display alarm control circuit, the display alarm control circuit has three tunnel outputs, one the tunnel connects the display that is used for display reminding information, two the tunnel connect the LED lamp that is used to show detected state, and three the tunnel connect the alarm that is used to send overload alarm.
Described display is a LCD; Described LED lamp comprises green, yellow and the red LED lamp that promising difference detected state is set; Described alarm is an audible-visual annunciator.
What the monitoring system in the utility model adopted is high-sensitive sensor, can be used for measuring airborne key index, comprise humiture, dust, volatile organic contaminant, formaldehyde and carbon dioxide etc., after the signal that is detected amplifies through the signals collecting amplifying circuit, reach central processing unit by duplex high precision A/D circuit and carry out signal Processing, result sends the display alarm control circuit to, correspondingly indicating the indoor air quality of user by the LED lamp again is to be in normally, which kind of level status of critical or police circles, every detection index be in normal, which kind of level status of critical or police circles.If any a certain or a few detection index exceeding standards, then send warning by alarm, provide the prompting suggestion accordingly by display simultaneously, suggestion takes those measures necessary to improve the air quality of corresponding index.
The utility model can be discerned the requirement whether IAQ (indoor air quality) satisfies ecological household automatically, can be in the continuous monitoring IAQ (indoor air quality), a kind of display interface of hommization is provided, be used to remind user's air quality to be in which kind of state, thereby make the user in time understand own ambient air quality, make the user according to actual conditions, prompting according to this device, take to improve targetedly measure, reduce indoor air pollution thus, improve the quality of living.
Description of drawings
Fig. 1 is a circuit structure block diagram of the present utility model.
Embodiment
As shown in Figure 1, sensor groups of the present utility model includes warm and humid sensor 1, dust sensor 2, volatile organic contaminant sensor 3, formaldehyde sensor 4 and carbon dioxide sensor 5 etc., also can detect the increase and decrease of index and the increase and decrease of respective sensor according to different user's requests.The output of each sensor is respectively by being connected to the input end of duplex high precision A/D circuit 6 behind the signals collecting amplifying circuit separately.In each the signals collecting amplifying circuit that joins with each sensor, all be provided with temperature-compensation circuit,, improve accuracy of measurement to reduce temperature drift.The output termination central processing unit 7 of duplex high precision A/D circuit 6, central processing unit 7 can adopt conventional single-chip microcomputer, have connected memory module 12 and data-out port 13 on it.The output of central processing unit 7 connects the display control module in the display alarm control circuit 8.Display alarm control circuit 8 is established three tunnel outputs altogether: the one tunnel connects display 9, be used to provide a certain index in the back of transfiniting the relevant information of the countermeasure this respect that should take; Two the tunnel connect LED lamp 10, are used for showing which kind of level status is every index that detects be in; Three road devices 11 taking alarm are used for sending warning when the detection index transfinites.
Above-mentioned used display 9 is preferably LCD, and its volume is little, clear display; Used LED lamp 10 comprises green, yellow and the red LED lamp that promising difference detected state is set, and is which kind of state with the present testing result of prompting user directly perceived; Used alarm 11 can be audible-visual annunciator, sending sound and light alarm, and the air quality that call user's attention is indoor, and take corresponding improvement measure according to prompting.
The utility model also can be made special software according to user's request, by control module, realizes intelligentized home air quality control.
