[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The present invention provides a remote monitoring method for tail gas emissions, such as Figure 1 As shown, the method comprises:

[0048] Step 101: Obtain data information of each time period collected by the remote emission management vehicle terminal within a preset period.

[0049] The remote emission management vehicle terminal can collect exhaust gas concentration, which can be NOx concentration, that is, nitrogen oxide concentration. The remote emission management vehicle terminal can also collect engine speed, water temperature, etc.

[0050] The remote emission management vehicle terminal collects the above parameters at a preset frequency within a preset period to obtain data information for each period within the preset period. The preset frequency can be determined according to the exhaust emission monitoring requirements, for example, a frequency greater than 1 Hz can be used for collection. In addition, the collection period of each parameter can be synchronized.

[0051] Step 102: Perform invalid data processing on the data information to obtain valid data.

[0052] Due to the complex actual road operating environment of vehicles, such as low temperature environment in winter, high altitude environment, long-term idling of vehicles, frequent engine start and stop, OBD failure, etc., all of which will affect exhaust emissions. Therefore, when monitoring exhaust emissions, it is necessary to process invalid data of the data information of each time period collected by the remote emission management on-board terminal in step 101 to obtain valid data, that is, the data required for exhaust emission monitoring.

[0053] Among them, the OBD fault can be a fault diagnosed by the engine ECU that affects exhaust emissions or detects abnormal exhaust emissions.

[0054] As an optional implementation, performing invalid data processing on the data information to obtain valid data includes:

[0055] Delete the data that affects the exhaust emission in the data information, and / or set the data that is less than zero in the data information to zero.

[0056] The invalid data may be data that affects exhaust emissions, or may be abnormal data that is less than zero.

[0057] Optionally, delete the data that affects exhaust emissions, including:

[0058] Delete one or more of the following data: data of vehicle diagnostic system failure, data of driving cycle duration less than a preset cycle duration, data of engine coolant temperature less than a preset temperature, data of ambient temperature not within a preset temperature range, data of atmospheric pressure less than a preset pressure, data of vehicle load not meeting load requirements, and data of the exhaust gas sensor not working normally;

[0059] Among them, the driving cycle duration is the time from engine start to engine shutdown.

[0060] Optionally, delete data of OBD faults, including:

[0061] The data in the period when the on-board diagnostic system fails is deleted, or at least the data in the driving cycle duration corresponding to the on-board diagnostic system failure is deleted.

[0062] For the OBD data remotely transmitted by the vehicle terminal, when an on-board diagnostic system fault (OBD fault) is displayed, one way is to delete the data during the OBD fault, including but not limited to engine speed, exhaust gas concentration, etc. Another way is to delete the data within the duration of the current driving cycle corresponding to the on-board diagnostic system fault, where the driving cycle duration is the time from engine start to engine shutdown. Of course, in addition to deleting the data within the duration of the current driving cycle corresponding to the on-board diagnostic system fault, the data corresponding to the previous n driving cycles and / or the subsequent m driving cycles can also be deleted, including but not limited to engine speed, exhaust gas concentration, OBD data, etc. Here, from engine start to engine shutdown is one driving cycle, and m and n are positive integers, and m and n can be the same or different.

[0063] The data affecting exhaust emissions also includes the data of frequent engine start and stop, and the data with a driving cycle duration less than the preset cycle duration can be deleted. Among them, the preset cycle duration can be determined according to the exhaust gas monitoring requirements or the actual working conditions.

[0064] The data affecting exhaust emissions also includes the data of engine cold start, and the data with the engine coolant temperature less than the preset temperature can be deleted. Among them, the preset temperature T1 can be determined according to the exhaust gas monitoring requirements or the actual working conditions.

[0065] The data affecting exhaust emissions also includes the data of low temperature in winter and extremely high temperature in summer, and the data with the ambient temperature outside the preset temperature range can be deleted. If the lower limit value of the preset temperature range is T2 and the upper limit value of the preset temperature range is T3, and T2 < T3, then the data less than T2 and greater than T3 can be deleted. Among them, the lower limit value T2 and the upper limit value T3 of the preset temperature range can be determined according to the exhaust gas monitoring requirements or the actual working conditions.

[0066] The data affecting exhaust emissions also includes the data of high altitude. The higher the altitude, the lower the atmospheric pressure. Therefore, the data with the atmospheric pressure less than the preset pressure can be deleted. The remote emission management vehicle terminal can collect the atmospheric pressure, calculate the altitude according to the atmospheric pressure, and delete the data with the atmospheric pressure < P1 kPa. Among them, P1 can be determined according to the exhaust gas monitoring requirements or the actual working conditions.

[0067] The data affecting exhaust emissions also includes the data of the exhaust gas detection sensor not working properly, and the data during the period when the exhaust gas sensor does not work properly can be deleted. The exhaust gas detection sensor can be a NOx sensor. The data with the NOx concentration > R1 ppm can be deleted, where R1 can be determined according to the exhaust gas monitoring requirements or the actual working conditions.

[0068] The data affecting exhaust emissions also includes the data of low vehicle load, and the data with the vehicle load not meeting the load requirements can be deleted.

[0069] Optionally, delete the data of vehicles whose load does not meet the load requirements, including:

[0070] One or more of the data of vehicle speed less than a preset vehicle speed, the data of engine torque percentage less than a preset torque percentage, and the data of engine power percentage less than a preset power percentage is deleted.

[0071] The engine torque percentage may be the actual engine torque percentage in the data collected by the remote emission management vehicle terminal, or the difference between the actual engine torque percentage and the friction torque percentage in the data collected by the remote emission management vehicle terminal. The engine power percentage may be calculated based on the speed, torque percentage and engine rated power.

[0072] There may be zero drift data in the data collected by the remote emission management vehicle terminal, that is, data less than 0 in the data information, such as exhaust NOx concentration <0. The data less than zero in the data information can be set to zero, that is, the NOx concentration is set to 0 to correct the zero drift characteristics of the sensor. Data greater than 0 in the data information is not processed. The operation of setting the data less than zero in the data information to zero can be performed after the data affecting exhaust emissions in the data information is deleted as described above.

[0073] Step 103: Calculate the total duration of valid data.

[0074] The total duration of the valid data is the total duration of the remaining data calculated by deleting the data that affects exhaust emissions from the data information collected by the remote emission management vehicle terminal for each time period within a preset period and setting the data that is less than zero in the data information to zero.

[0075] Step 104: Calculate the average exhaust gas concentration value and the average exhaust gas specific emission value according to the exhaust gas concentration of the valid data.

[0076] The average value of the exhaust gas concentration values ​​collected within the total time of valid data is calculated to obtain an average exhaust gas concentration value, wherein the unit of the exhaust gas concentration is ppm.

[0077] The total exhaust emission mass is calculated based on the exhaust concentration value, engine intake volume and fuel injection volume collected within the total time of valid data, and the total engine output power is calculated based on the engine speed and torque collected within the total time of valid data. The ratio of the total exhaust emission mass to the total engine output power is taken as the average exhaust specific emission value. The unit of specific emission is g / kWh.

[0078] Step 105: remotely monitor exhaust emissions based on the total duration of valid data, the average exhaust concentration value, and the average exhaust ratio emission value.

[0079] As an optional implementation, remote monitoring of exhaust emissions is performed based on the total duration of valid data, the average exhaust concentration value, and the average exhaust ratio emission value, including:

[0080] When the total duration of valid data is greater than the preset total duration, the average exhaust concentration value is greater than the preset concentration value, and the average exhaust emission ratio value is greater than the preset emission ratio value, it is determined that the vehicle carrying the remote emission management on-board terminal has abnormal emissions within the preset period.

[0081] As another optional implementation, remote monitoring of exhaust emissions may be performed based on the total duration of valid data, the average exhaust concentration value, and the average exhaust ratio emission value, and may also include:

[0082] When the total duration of valid data is greater than the preset total duration and the average exhaust gas concentration value is greater than the preset concentration value, it is determined that the vehicle carrying the remote emission management on-board terminal has abnormal emissions within the preset period.

[0083] As another optional implementation, remote monitoring of exhaust emissions may be performed based on the total duration of valid data, the average exhaust concentration value, and the average exhaust ratio emission value, and may also include:

[0084] When the total duration of valid data is greater than the preset total duration and the average exhaust gas emission ratio value is greater than the preset emission ratio value, it is determined that the vehicle carrying the remote emission management on-board terminal has abnormal emissions within the preset period.

[0085] Optionally, after determining that a vehicle carrying a remote emission management vehicle terminal has abnormal emissions within a preset period, an early warning may be issued to the vehicle regarding the abnormal emissions within the preset period.

[0086] If the total duration of valid data is not greater than the preset total duration, the average exhaust gas concentration value is not greater than the preset concentration value, and the average exhaust gas emission ratio value is not greater than the preset emission ratio value, it is determined that the vehicle carrying the remote emission management vehicle terminal has normal emissions within the preset period. In addition, if the total duration of valid data is not greater than the preset total duration and the average exhaust gas concentration value is not greater than the preset concentration value, it is determined that the vehicle carrying the remote emission management vehicle terminal has normal emissions within the preset period. Alternatively, if the total duration of valid data is not greater than the preset total duration and the average exhaust gas emission ratio value is not greater than the preset emission ratio value, it is determined that the vehicle carrying the remote emission management vehicle terminal has normal emissions within the preset period. When it is determined that the vehicle carrying the remote emission management vehicle terminal has normal emissions within the preset period, no vehicle warning is issued.

[0087] The present invention can realize remote monitoring of exhaust emissions based on the data of the vehicle-mounted terminal by calculating the total duration of effective data, the average exhaust concentration value and the average exhaust ratio emission value.

[0088] The present invention also provides a method for remote monitoring of exhaust emissions, such as Figure 2 As shown, the method comprises:

[0089] Step 201: Obtain data information of each time period collected by the remote emission management vehicle terminal within a preset period.

[0090] The step 201 and Figure 1 The step 101 shown is similar and will not be described again here.

[0091] Step 202: Perform invalid data processing on the data information to obtain valid data.

[0092] The step 202 is Figure 1 The step 102 shown is similar and will not be described again.

[0093] Step 203: Calculate the total duration of valid data.

[0094] The step 203 and Figure 1 The step 103 shown is similar and will not be described again.

[0095] Step 204: Calculate the average exhaust gas concentration value and the average exhaust gas specific emission value according to the exhaust gas concentration of the valid data.

[0096] The step 204 is Figure 1 The step 104 shown is similar and will not be described again here.

[0097] Step 205: When the total duration of valid data is greater than the preset total duration, the average exhaust concentration value is greater than the preset concentration value, and the average exhaust emission ratio value is greater than the preset emission ratio value, it is determined that the vehicle carrying the remote emission management on-board terminal has abnormal emissions within the preset period.

[0098] Optionally, after determining that a vehicle carrying a remote emission management vehicle terminal has abnormal emissions within a preset period, an early warning may be issued to the vehicle regarding the abnormal emissions within the preset period.

[0099] If the total duration of valid data is not greater than the preset total duration, the average exhaust gas concentration value is not greater than the preset concentration value, and the average exhaust gas specific emission value is not greater than the preset specific emission value, it is determined that the vehicle carrying the remote emission management vehicle terminal has normal emissions within the preset period. If it is determined that the vehicle carrying the remote emission management vehicle terminal has normal emissions within the preset period, no vehicle warning will be issued.

[0100] Step 206: Obtain the emission results of the vehicle within a plurality of preset periods, and obtain the number of times the vehicle's emissions are abnormal; calculate the abnormal emission ratio according to the number of times the vehicle's emissions are abnormal; if the abnormal emission ratio exceeds the preset ratio, issue a vehicle warning.

[0101] If the abnormal emission ratio does not exceed the preset ratio, no vehicle warning will be issued.
