The tail gas pollution monitoring system can realize real-time dynamic monitoring of the tail gas of fuel automobile vehicles in a to-be-measured area. The size of a tail gas signal A and the size of a minimum tail gas signal L are compared. If the tail gas signal A is smaller than the minimum tail gas signal L, the tail gas signal A is regarded as an invalid tail gas signal A1, that is, data loss occurs. Then, the tail gas signal collected last time is taken as the lost data, so as to ensure the accuracy of the dynamic change air quality thermal map. A continuous invalid number N is set to distinguish between fuel automobile tail gas sensor failure and transmission interference. In order to more accurately judge whether the fuel automobile tail gas emission meets the national standard, a continuous abnormal number M is set, so that the tail gas pollution monitoring system is more practical and universal.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of monitoring, in particular to a tail gas pollution monitoring system. BACKGROUND

[0002] The pollution of fuel vehicles is mainly discharged near the ground on urban roads, and the main pollutants are NOx and smoke dust, which are the main culprits of urban pollution. In order to improve air quality, in the field of transportation, it is necessary to accelerate the elimination of yellow label vehicles and old vehicles. Article 53 of the Air Pollution Prevention and Control Law of the People's Republic of China clearly stipulates that under the condition of not affecting normal traffic, the atmospheric pollutant emission status of motor vehicles on the road can be supervised and sampled by remote sensing monitoring and other technical means.

[0003] However, the traditional remote sensing monitoring and other technical means for supervising and sampling the atmospheric pollutant emission status of motor vehicles on the road cannot dynamically monitor the entire city vehicle tail gas pollution state. With the progress of current communication and data processing, a long-term dynamic monitoring system can be established for the entire city fuel vehicle. However, due to the large number of vehicle tail gas vehicles, and the simultaneous ignition and start of many vehicles in the same road area at the same time, especially during traffic jams, there are many vehicles in the same road area, and the tail gas monitoring data is relatively redundant. When transmitting data, mutual interference may occur, resulting in data loss. SUMMARY

[0004] In view of the above situation, the purpose of the present application is to provide a tail gas pollution monitoring system, which can dynamically monitor the tail gas of fuel vehicles in the test area in real time, and when data loss occurs, the last collected tail gas signal can be used as the lost data to ensure the accuracy of the dynamic air quality thermal map.

[0007] S2, the data processing module according to the vehicle model in the positioning signal B, call the corresponding minimum tail gas signal L in the database, then compare the size of tail gas signal A and minimum tail gas signal L, the tail gas signal A less than minimum tail gas signal L is regarded as invalid tail gas signal A1, otherwise, regarded as effective tail gas signal A2, finally invalid tail gas signal A1, effective tail gas signal A2 and corresponding positioning signal B1, positioning signal B2 are sent to the calibration module;

[0008] S3, the calibration module according to the license plate number in the positioning signal B1, call the corresponding tail gas signal C after the last calibration module calibration in the database, with tail gas signal C instead of invalid tail gas signal A1, while recording the continuous invalid number N of this license plate number;

[0009] The calibration module according to the vehicle model in the positioning signal B2, call the corresponding standard tail gas signal H in the database, then compare the size of effective tail gas signal A2 and maximum tail gas signal H, effective tail gas signal A2 greater than maximum tail gas signal H is regarded as abnormal tail gas signal A2-1, while recording the continuous abnormal number M of this license plate number, otherwise, regarded as normal tail gas signal A2-2;

[0010] S4, the control module receives tail gas signal C, positioning signal B1 and continuous invalid number N output by the calibration module, when the continuous invalid number N is greater than 5, the tail gas sensor of the fuel automobile corresponding to the license plate number in the positioning signal B1 is regarded as invalid, the prewarning module is controlled to remind the owner of this license plate number to replace the tail gas sensor in time in the form of short message, and the display module is controlled to flash on the screen to remind the relevant staff, so that the relevant staff can directly call the vehicle information through the display module;

[0011] The control module receives positioning signal B2, abnormal tail gas signal A2-1 and continuous abnormal number M output by the calibration module, when the continuous abnormal number M is greater than 3, the tail gas emission of the fuel automobile corresponding to the license plate number in the positioning signal B2 is not regarded as conforming to the national standard, the prewarning module is controlled to remind the owner of this license plate number not to run the vehicle in the form of short message, and the prewarning module is controlled to notify the relevant staff to supervise and remind in the form of short message, and the display module is controlled to flash on the screen to remind the relevant staff, so that the relevant staff can directly call the vehicle information through the display module, when the continuous abnormal number M is less than 3, the prewarning module does not work.

[0012] The control module receives the positioning signal B2 and the normal tail gas signal A2-2 output by the calibration module, and the early warning module does not work.

[0013] Compared with the prior art, the present application has the following advantages due to the adoption of the above technical solutions.

[0014] 1. The fuel automobile vehicle tail gas in the area to be measured can be monitored in real time, and the tail gas signal A smaller than the minimum tail gas signal L is regarded as an invalid tail gas signal A1, that is, data loss occurs, and then the tail gas signal collected last time is used as the lost data, so as to ensure the accuracy of the dynamic change air quality thermodynamic map.
