Automobile exhaust has become a major source of urban air pollutants in one government at all levels from development planning, urban construction, energy supply different aspects of the comprehensive measures to ease vehicle emissions on the atmospheric environment. Also study and formulate relevant policies and measures to promote the establishment of more convenient and efficient public transport system to reduce transport sector energy consumption and emissions. Mobile exhaust Analyzer Is used to detect cars in motion the process of exhaust gas emission targets and the design of a testing device, it will control emissions, the establishment of low-carbon life, play a role. Mobile vehicle exhaust Analyzer When the car starts, the mobile vehicle exhaust Analyzer Start pumping air pump from the vehicle exhaust emission sampling, after the dust to oil, water treatment components into the gas analysis IRidium100 Within the internal infrared treatment, collecting CO, CO2, HC concentration data, and then enter through the external exhaust gas O2, NOx sensors, collect the corresponding O2, NOx in the exhaust gas concentration data. The data is the result signal detection, amplification and processed into a number of results, by IRidium100 The RS-232 serial port spread to the microprocessor. Microprocessor through the statistics, the average processing and storage such as algorithms, according to custom data communication protocols on environmental protection package, through the GSM / GPRS / CDMA data communication or short message communication reached a specified upper management platform. Analyzer There are operations on the LCD menu, the user menu via keyboard operation, availability of equipment, working conditions and exhaust gas analysis, LCD display can be CO, CO2, HC, O2, NOx results of specific test data. Mobile vehicle exhaust Analyzer The structure shown in Figure 1. Mobile vehicle exhaust Analyzer Hardware Design Exhaust Analyzer Analysis of components of gas companies by the British CITY IRidium100 Type of gas analysis module. It is through internal infrared treatment, collecting CO, CO2, HC of the concentration data. IRidium100 O2 sensors can be external and NOx sensors are O2 and NOx concentration data. SCM system using C8051F020, it has two serial ports, one serial port connection IRidium100 Another serial port to connect GSM / GPRS or CDMA communication module, a custom communication protocols and upper management platform for data exchange. Input power supply directly connected car DC12V ~ DC24V, DC12V available to convert IRidium100 , While providing a DC5V power output to the microcontroller and communication modules. Single chip sampling by pumping air pump relay control the work of the main control intake and exhaust of the action. Relay control pump pumping, usually in a disconnected state, when the exhaust gas analysis system began to relay power to pump pumping work 5 minutes. GSM module Siemens MC37I. The module is a full-featured mobile communications industry module, CPU through the serial port control and data transfer it can be transmitted, including SMS, CSD, GPRS, etc., data. CPU module is controlled by the AT command line with ETSI standard GSM07.07 and GSM 07.05. Mobile vehicle exhaust Analyzer Software Design Exhaust Analyzer Work pattern Special Purpose Vehicle Exhaust Analyzer Designed with four modes: manual mode, under the boot menu using the keyboard, perform a process of exhaust gas analysis; automatic mode, when the day time set up automatically when the process of implementation of an exhaust gas analysis; command mode, when receiving an order to upper management platform, the implementation of an exhaust gas analysis process; calibration mode, turned on through the menu options to enter, conduct a calibration process exhaust. One, manual mode and calibration mode provided by the LCD main menu, in the field through the keyboard keys trigger, then perform the appropriate control commands. Manual mode, the need to immediately exhaust analysis, manually enter the main menu, then select a tail gas detection, or choose to implement n-tail test (n from the set menu option input), conducted by or second exhaust gas analysis.
