Description

A kind of prediction of air quality system and method
Technical field
The present invention relates to prediction of air quality technical fields, and in particular to a kind of prediction of air quality system and method.
Background technology
AQI (Air Quality Index, air quality index) is the parameter for reporting daily air quality.Describe sky Gas cleans or the degree of pollution, and the influence to health.The emphasis of air quality index be assessment breathing a few houres or Influence of several days pollution air to health.Environmental Protection Agency calculates air quality index and passes through five main pollution norms:Ground level ozone, Particulate Pollution (also referred to as particulate matter), carbon monoxide, sulfur dioxide, nitrogen dioxide.For these pollutants, Environmental Protection Agency has set up National Ambient Air Quality Standards, to protect public health.Two kinds of pollutants of the particle in ground level ozone and air are constituted Biggest threat of this country to human health.AQI is the abbreviation of ambient air quality index, is in March, 2012 country's publication New Air Quality Evaluation standard, pollutant monitoring be 6:Sulfur dioxide, nitrogen dioxide, PM10, PM2.5, carbon monoxide and Ozone, data update once per hour.The unified evaluation criterion of this 6 pollutants is presented in AQI.Air quality index classification It is excellent to be divided into 0-55;51-100 is good;101-150 slight pollutions;151-200 intermediate pollutions;201-300 serious pollutions;>300 is serious Pollution.
Ethernet (Ethernet) is referred to being created by Xerox companies and be developed jointly by Xerox, Intel and Digital Equipment Corporation Baseband LAN specification, be the most general communication protocol standard that current existing LAN uses.Ethernet uses CSMA/ CD (csma and collision detection) technology, and operated on a plurality of types of cables with the rate of 10M/S.Ether Net is similar with IEEE8023 series standards.
Thus there are a kind of fresh air purifying control system based on prediction of air quality, including Programmable logical controller Device, the programmable logic controller (PLC) are separately connected indoor CO2 apparatus for measuring concentration, interior VOC apparatus for measuring concentration, Indoor Temperature Spend measuring device, indoor relative humidity measuring device, outdoor temperature measuring equipment, outside relative humidity measuring device, filter Differential pressure measurement device, apparatus for measuring air quantity, air-treatment quality detection device, frequency conversion fan control device, dynamoelectric water valve control Device, Electric air valve control device and communication device, the communication device are connected with automatic control and simulation framework, the automatic control and Simulation framework connects building automation host computer by Ethernet, and the automatic control connects air quality with simulation framework by internet Forecast servers.
The prediction of air quality server be Environmental Protection Agency, environment monitoring center public prediction of air quality website clothes Business device or the authoritative media server for issuing prediction of air quality.
The automatic control and simulation framework are to be loaded with simulation of energy consumption software and the general commercial computer of control software.
The filter differential pressure measuring device, frequency conversion fan control device, dynamoelectric water valve control device and Electric air valve Control device all can be one or more.
Intelligence degree is high in this way, and control is scientific and reasonable, it is ensured that and fresh air purifying effect improves filter service life, New atmosphere quality and indoor air quality are monitored.It can be based on prediction of air quality and formulate fresh air purifying control strategy with to new Wind purification system is rationally controlled.It can be according to the parameter of differential pressure pickup, using Electric air valve control device to various controls Air-valve carries out keying control, for example can realize the bypass to high-drag filter by opening filter bypass air-valve, reduces system System resistance.It frequency conversion fan control device can be used to carry out frequency control to the wind turbine in New-air purifying system, make its energy-saving run, Energy saving of system effect is good.
It is exposed in order to prevent to be easy to be destroyed in the environment, prediction of air quality server is just set to server machine In cabinet, the server cabinet includes cabinet cabinet, and in order to efficiently use space, cabinet cabinet, which is often stablized, to be provided to vertically Framework on plate, but because of the inducement of ambient brightness, brightness can usually continue to change, and therefore, server is set in maintenance When prediction of air quality server in cabinet, the often maintenance difficulties increase because of ambient brightness deficiency, in addition because Cabinet cabinet and prediction of air quality server can not move, and also increase the difficulty of maintenance, cause to safeguard more time-consuming Laborious situation occurs.
