The carbon dioxide content pick-up unit is based on following principle of work in the urban air of the present invention:
Networking synchronous acquisition test data: in the urban area, the monitoring point is set, and in the net territory, monitoring master station is set by square grid.A suitable high-rise building is selected in each monitoring point, on this external walls of building wall, settles the carbon dioxide pick-up unit, and locates to settle the carbon dioxide detector in the passageway of building etc.According to the time of prior setting; The carbon dioxide content pick-up unit carries out the detection of carbon dioxide content synchronously in the urban air of all monitoring points; And will detect data by carbon dioxide content detector in the urban air and pass through broadband line or telephone wire, flow to monitoring master station immediately and analyze and handle.
Detect the air of differing heights: because the aerial density of carbon dioxide is bigger, often be prone to be sunken to the bottom of air, owing to the influence of wind-engaging or hot-air rising convection current, it is uneven causing differing heights carbon dioxide in air content again.Carry out the detection of carbon dioxide content in order to collect representational air; The breather line of vertical arrangement pick-up unit on the external wall of high-rise building; On breather line, several draft tube are set, more than the highest point draft tube, are disposed with detector tube, air pump, escape pipe by the design height equidistance.Before the detection, the turnover panel flap valve in all draft tube is all closed, and is locked by electromagnetic switch.During detection; Air pump is started in the control of carbon dioxide detector; And open the flap valve electromagnetic switch of each draft tube by regulation order and time; Open the flap valve (guaranteeing at every turn to have only 1 draft tube air inlet) of draft tube one by one, let the fresh air conveying of differing heights carry out the detection of carbon dioxide content to detector tube, and from escape pipe output air to be detected.
Improve the fiduciary level that carbon dioxide detects: on the plate-turning door of detector tube and each draft tube, all settle a flap valve to open and close self-checking unit (constituting) by permanent magnet and Hall switch.Whenever flap valve is closed, permanent magnet on the flap valve and the Hall element on the gate seat near, the resistance of Hall element diminishes and lets electric current pass through; Whenever the flap valve unlatching, the permanent magnet on the flap valve is away from the Hall element on the gate seat, and the resistance of Hall element becomes does not allow electric current to pass through greatly.All flap valves are opened and closed self-checking unit numbering back insert carbon dioxide content detector in the urban air, on this detector, just can grasp the situation that each flap valve is opened or closed., air in the detector tube is not replaced by appointment and causes that mistake surveys because the flap valve of draft tube is opened or closed by the control regulation to avoid occurring.
The sensing of carbon dioxide: the carbon dioxide content pick-up unit is the detection of in detector tube, carrying out Carbon Dioxide in Air content in the urban air of the present invention; Be drawn into fresh air to draft tube by air pump during each the detection, discharge the air that had detected from gas outlet from tested height.After tested fresh air is transported to detector tube through breather line; Close the flap valve at detector tube two ends; Form the detection space (volume of air of regulation) of sealing; Carry out the detection of carbon dioxide content simultaneously by two carbon dioxide sensors in the detector tube, and by temperature sensor test real-time temperature, to revise its influence.
