Remote sensing detection is a kind of emission test method which does not affect the normal passage of the road. It is suitable for exhaust inspection in the vehicle exhaust. This standard specifies the use of remote sensing detection method in real time on the actual road driving diesel vehicle exhaust pollutant emission measurement side Method, instrument installation requirements, results determination criteria and emission limits. Appendix A, Appendix B, Appendix C, Appendix D are normative appendices, Appendix E is an informative appendix. This standard is the first release. This standard is organized by the Department of Environmental Protection of the Ministry of Environmental Protection and the Department of Science and Technology Standards. The drafting of this standard. China Environmental Science Research Institute, Beijing Institute of Technology, China University of Science and Technology. This standard is approved by the Ministry of Environmental Protection on July 27,.2017. This standard shall come into force as of the date of promulgation. Since the implementation of this standard date, the existing relevant local remote sensing testing standards abolished. This standard is explained by the Ministry of Environmental Protection. In the use of diesel vehicles exhaust pollutant measurement methods and technical requirements (remote sensing detection method)1 Scope of applicationThis standard specifies the use of remote sensing detection method in real time on the actual road driving diesel vehicles exhaust pollutant emissions measurement Method, instrument installation requirements, results determination criteria and emission limits. This standard applies to fixed remote sensing detection and mobile remote sensing detection. This standard applies to GB/T 15089 of the M class and N class equipped with compression ignition engine car.2 normative reference documentsThis standard refers to the following documents or the terms thereof. For undated references, the latest edition of this document applies standard. GB 3847 Vehicle Compression Ignition Engine and Compression Ignition Engine Automobile Exhaust Smoke Emission Limits and Measurement Methods Classification of Motor Vehicles and Trailers GB/T 21255 motor vehicle speedometer General technical requirements for telemetry equipment for motor vehicle tail gas JB/T 11996 Standard Terminology and Definitions for JJF 10013 terms and definitionsThe following terms and definitions apply to this standard. 3.1 M and N vehicle vehicles of category Mand N According to GB/T 15089-2001 regulations. Class M cars are motor vehicles that have at least four wheels and are used to carry passengers. The M1 class refers to the driver's seat Within the seat number of not more than nine passenger cars. Class N vehicles are motor vehicles that have at least four wheels and are used for loading. 3.2 Remote sensing method Method of measuring the exhaust pollutants in automobile by means of optical principle. 3.3 Stationary remote sensing Fixed installation, can be unattended continuous operation, test results data sent directly to the environmental protection department or its commissioning machine Structure Fixed remote sensing detection can be divided into two types. vertical remote sensing detection and horizontal remote sensing detection. 3.4 Mobile remote sensing With a special car loading, according to the need to randomly select the measurement location, the use of equipment in accordance with the provisions of the installation commissioning, After the work is completed, the equipment will be collected and the test result data will be sent directly to the environmental protection department or its commission. 3.5 Vertical remote sensing A fixed remote sensing detection method. Arrange the detection instrument optical path in the vertical direction to obtain the vehicle on the road to be tested And its emissions of pollutants and other related information to achieve rapid detection of vehicle exhaust pollutants remote sensing detection method. 3.6 Horizontal remote sensing A fixed remote sensing detection method. Arrange the detection instrument in the horizontal direction to obtain the vehicle on the road to be tested And its emissions of pollutants and other related information to achieve rapid detection of vehicle exhaust pollutants remote sensing detection method. 3.7 Exhaust pollutant Refers to the exhaust emissions of particulate matter and particulate matter. This standard refers to nitric oxide (NO) and particulate matter (with opacity And blackness meter). 3.8 Opacity opacity Refers to the light emitted from the light source through the diesel exhaust smoke to reach the optical receiver receiver percentage, recorded as "%". 3.9 Ringelmann blackness A mixture of exhaust pollutants and Ringermann concentration map measured by a smoke and dust concentration representation, divided into 0 to 5 level. There are six corresponding Ringermann concentration maps, 0 for all white, 1 level of blackness of 20%, 2 for 40%, 3 for 60%, 4 for 80%, 5 for all black.4 measurement requirementsMeasured in accordance with the measurement method specified in Appendix A, the technical parameters of the test equipment shall comply with the requirements of Annex AA Record and real-time sharing of data should be consistent with the requirements of Appendix B and Appendix C. The test report format is shown in Appendix E. The equipment should be calibrated and checked in accordance with the relevant requirements in Appendix D before and after use.5 pollutant discharge limitsInstalled compression-ignition engine The use of remote sensing detection of emission limits in Table 1. Table 1 Installed Compression Ignition Engine Vehicle Pollutant Emission Limits Opacity (%) Ringermann blackness NO (1) (volume concentration) Limit 30 1 1500 × 10-6 (1) NO limits are only used for screening high-lift vehicles6 result judgmentThe results of the same contaminant test for two or more consecutive periods exceed the emission limits specified in Table 1, and the measurement interval is 6 Within the month, the vehicle is judged to be unqualified.7 standard implementationThis standard shall come into force as of the date of promulgation.Appendix A(Normative appendix) Measurement methods A.1 Overview This appendix specifies the method of remote sensing detection. A.2 Measurement conditions A.2.1 Measurement location The measurement site should be a long road with a good view and a smooth road surface. The measurement section may be a single lane section or a multi-lane section, the distance between each vehicle passing through is not less than 1.0s, The vehicle passing time is less than 1.0s. The measurement result is invalid. A.2.2 Environmental conditions The atmosphere should meet the following conditions. - no rain, fog, snow; - no obvious dust; - wind speed ≤5.0m/s; - Ambient temperature. -20.0 ~ 45.0 ℃; - relative humidity ≤ 85.0%; - Atmospheric pressure. 70.0 to 101.4 kPa. A.3 Measurement method A.3.1 Equipment installation The measuring equipment shall comply with Annex AA. The measuring equipment shall be installed in accordance with AA.4. A.3.2 Equipment commissioning - preheat the analyzer into the measurement application; - enter the information required in Appendix B and Appendix E; - adjust the transmitter and receiver; - adjust the camera focal length, aperture to ensure that the shooting of a clear diesel vehicle emissions Ringermann black degree and license parts picture; - Enter the calibration interface for zero scale and full scale calibration. A.3.3 Measurement and recording When the diesel vehicle passes the inspection point, the remote sensing detection device automatically shoots and identifies the vehicle license plate number, automatically measures the vehicle pollutant Concentration, shooting Rhegman blackness, and the collected data and calculation results into the database.
