Abstract
The utility model discloses a kind of public lavatory exhaust system detected based on Smoke Detection and ammonia, comprise handheld terminal, some supports and monitoring modular, to the road surface of pressure be needed to be divided into some regions, and at each region frame support, above support, monitoring modular is installed; The radio receiving transmitting module that described monitoring modular comprises power supply for powering, single-chip microcomputer and is connected with single-chip microcomputer; Handheld terminal is connected by wireless network with radio receiving transmitting module; Ultrasonic distance measuring module real-time monitors the distance on road surface, and data are passed to single-chip microcomputer, and the data received compare with the standard value of setting by single-chip microcomputer, and sends the result compared to handheld terminal by radio receiving transmitting module.This device degree of accuracy is high, good energy-conserving effect.This system can better improve air ambient in public lavatory.
Description
Technical field
The utility model relates to Smoke Detection and gas detect, by the monitoring to ETS and ammonia concentration, controls exhaust fan work, particularly relates to a kind of public lavatory exhaust system detected based on Smoke Detection and ammonia.
Background technology
Public lavatory majority does not now have exhaust system, and compared with between domestic sanitary, public lavatory causes its inner air muddiness unpleasant due to improper ventilation and frequent use.In addition, in some public lavatories, smoking population has increased the weight of air pollution degree further, makes public lavatory air more allow people be difficult to stand.
Current most of exhaust fan, is all directly manipulated by user.As accomplishing with driveing with pass during family expenses, but in public lavatory, in default of management, manual control is difficult to realize, and therefore wastes energy very much.
Utility model content
The purpose of this utility model, is to provide a kind of public lavatory exhaust system detected based on Smoke Detection and ammonia, better can improve the environment of public lavatory and energy conservation.
In order to reach above-mentioned purpose, solution of the present utility model is:
Based on the public lavatory exhaust system that Smoke Detection and ammonia detect, comprise the power supply for powering, single-chip microcomputer and the ion type smog sensor be connected with single-chip microcomputer respectively, ammonia concentration sensor, exhaust fan driver module; Described ion type smog sensor detects smokescope in real time and sends smokescope data-signal to single-chip microcomputer, ammonia concentration sensor detects ammonia concentration and in real time to single-chip microcomputer transmission ammonia concentration data-signal, and the smokescope data-signal received and ammonia concentration data-signal compare with preset value and determine whether starting exhaust fan driver module by single-chip microcomputer respectively.
Further, described exhaust fan driver module comprises the optical coupled switch, relay and the exhaust fan that connect successively, and single-chip microcomputer is connected with optical coupled switch; When smokescope and ammonia concentration in public lavatory air are all low than preset value, single-chip microcomputer sends to optical coupled switch and cuts out exhaust fan signal, and optical coupled switch drives cut-off exhaust fan; When smokescope in public lavatory air or ammonia concentration are than preset value height, single-chip microcomputer sends to optical coupled switch and opens exhaust fan signal, and optical coupled switch drives cut-off exhaust fan.
Further, the chip of STC89C52 model that what described single-chip microcomputer adopted is.
Further, described ion type smog sensor adopts the sensor of HIS-07 model.
Further, described ammonia concentration sensor adopts the sensor of MQ-135 model.
Adopt after such scheme, the utility model be a kind of can the exhaust system of environmentally situation self-contained operation, air ambient in public lavatory can better be improved, safeguard health, and can also the switch of automatic control exhaust fan, energy conservation.
Accompanying drawing explanation
Fig. 1 is the utility model general frame figure.
Fig. 2 is utility model works flow chart.
Detailed description of the invention
Below with reference to accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of public lavatory exhaust system detected based on Smoke Detection and ammonia comprises for the power supply of power supply, single-chip microcomputer and the ion type smog sensor be connected with single-chip microcomputer respectively, ammonia concentration sensor, exhaust fan driver module; Described exhaust fan driver module comprises the optical coupled switch, relay and the exhaust fan that connect successively, and single-chip microcomputer is connected with optical coupled switch.
Described ion type smog sensor adopts the sensor of HIS-07 model, is arranged on by this sensor and the most easily smog is detected and away from the position of exhaust fan, detect smokescope in real time and also send smokescope data-signal to single-chip microcomputer.
Described ammonia concentration sensor adopts the sensor of MQ-135 model, is arranged on by this sensor and the most easily ammonia is detected and away from the position of exhaust fan, detect ammonia concentration in real time also to single-chip microcomputer transmission ammonia concentration data-signal.
Described single-chip microcomputer adopts the chip of STC89C52 model, the smokescope data-signal received and ammonia concentration data-signal compare with preset value and determine whether starting exhaust fan driver module by this single-chip microcomputer respectively, determine whether send work order to exhaust fan.When smokescope and ammonia concentration in public lavatory air are all low than preset value, single-chip microcomputer sends to optical coupled switch and cuts out exhaust fan signal, and optical coupled switch drives cut-off exhaust fan; When smokescope in public lavatory air or ammonia concentration are than preset value height, single-chip microcomputer sends to optical coupled switch and opens exhaust fan signal, and optical coupled switch drives cut-off exhaust fan.
Described power supply needs that 5V power supply is sensor, single-chip microcomputer STC89C52 and optical coupled switch are powered; 12V power supply is needed to be that relay is powered.
Be illustrated in figure 2 workflow diagram of the present utility model, described ion type smog sensor HIS-07 and ammonia concentration sensor MQ-135 real-time data collection, the data collected are transferred to single-chip microcomputer STC89C52, single-chip microcomputer STC89C52 judges whether smokescope and ammonia concentration exceed standard, if exceeded standard just start exhaust fan, otherwise close exhaust fan.When ammonia concentration is too high in public lavatory, automatically start exhaust fan, reduce peculiar smell; When smokescope is too high in public lavatory, automatically start exhaust fan, reduce smog.
The public lavatory exhaust system detected based on Smoke Detection and ammonia of the present utility model be a kind of can the exhaust system of environmentally situation self-contained operation, air ambient in public lavatory can better be improved, safeguard health, and can also the switch of automatic control exhaust fan, energy conservation.
Above embodiment is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection domain.
