Industrial tablets, power ambient air automatic monitoring system application case is introduced

Ambient air quality automatic monitoring system is composed of a central station and several sub-stations, sub station data acquisition control system and the data processing center control system through the communication network data transmission, data collection and processing, remote control and data in the central station through data processing can form statistical reports on the environmental air quality. System software consists of central station software and sub station of two parts, the two organic combine, coordinated operation of the whole monitoring system, complete the data acquisition and remote communication control of monitoring instruments and data processing, and report form. System of atmospheric pollution monitor: including SO2, NOx, NO、NO2) , CO, O3, air particulate matter ( TSP) , such as PM10 monitor ( According to user needs matching) 。 Weather instrument: can measure wind speed, wind direction, temperature, relative humidity, atmospheric pressure, According to user needs matching rainfall, sunshine, etc. ) 。 Field calibration system: include a variety of standard gas, a zero gas generator, a calibration dynamic gas generator. Sub station computer: continuous automatic collection and atmospheric pollution monitor, weather instrument, calibration data and status information, etc. Preprocessing and storage, and waiting for the central computer polling or instructions. Sampling gas collector: the sampling head, main and branch joint, suction fan, exhaust, etc. Remote data communication equipment: cable transfer or directly use the wireless PC card ( Support for GPRS or CDMA) 。 System software system software development based on the infrastructure, the highly concentrated on function design, maximum limit reduce the requirement for the operating system, almost does not depend on other applications support, low operating environment requirements, easy to install and use and maintenance, is a green software, suitable for long-term stable operation. Sub station 1, test software project can be set by the user configuration, adapt to different sub station configuration. 2, for A instrument output analog signal acquisition, and A/D conversion. 3, can be directly by RS232 and RS485 mouth acquisition with communication function of instrument of data at a time. 4, can contact with the center distance through GPRS or CDMA, achieve data transmission and control. 5, can be three times per minute to collect data, dynamic graphical display, average in minutes as the basic data, automatically generate data file. 6, can refer to any day of the original data, statistics hours and average pollution index, generating daily, weekly, monthly, annual reports, etc. , and can print output. 7, can be any day of the original data and statistical average hours to export the text file. 8, can control the zero and calibration of an instrument operation. 9, can take the initiative to call to the remote data sent any day any time. Central station 1, flexible user configuration function: can adapt to different sub station configuration. 2, a variety of data transfer mode optional: cable ( Telephone or broadband) Way and wireless ( GPRS, etc. ) Way. 3, you can remote adjustable stand at any time the history of the original data, the mean optional minutes or hours. Also can be real-time monitoring data and the working state of the child stand to be obtained, and the dynamic display of graphically. 4, the child stood after the original data were obtained to the central station can be automatically stored in the corresponding database. Central station data processing system can be based on this, any access to the corresponding sub station of raw data, statistics hours mean and pollution index, and can be displayed graphically. 5, each station can be annual statistical journal data into the database, generate statistics can be submitted to the journal, weekly statistics, monthly statistics and report statistics. 6, any day of the original data and hour average export to TXT text format or EXCEL format. 7, can through the remote control station data acquisition system, remote monitoring of the monitoring equipment. Guangzhou industrial tablet android hardware configuration can meet the above functions need interface, on-board quad-core Cortex ® - A9 architecture, main frequency 1. 4 GHZ, integrated Android 4. 4. 2/5. 1 system, the rich resources of peripheral interface, the default RS232 4 road. Two way can be used as interface RS485 bus and have a standard RJ45 front-end ports, 2 USB Host interface, support for the mouse, keyboard, U disk and other equipment, support SD card expanded memory, wireless wifi, bluetooth, etc.
