Description

Technical Field

[0001] This invention relates to the field of testing technology for road and non-road mobile sources, and in particular to a mobile source on-site enforcement device integrated with an environmental data platform, used to meet the closed-loop on-site enforcement verification requirements of the environmental data platform. Background Technology

[0002] Currently, the "Emission Limits and Measurement Methods for Pollutants from Heavy-Duty Diesel Vehicles (China VI) (National Standard GB 17691-2018)" and the "Technical Requirements for Emission Control of Pollutants from Non-Road Diesel Mobile Machinery (Environmental Standard HJ 1014-2020)" have made requirements for the installation and data transmission specifications of vehicle-mounted terminals, requiring the national environmental protection data platform to conduct data analysis and statistics and form clues for tracking violations after receiving data.

[0003] The above two national environmental protection standard documents require: (1) The operating status data uploaded by the on-board terminal of heavy-duty diesel vehicles includes vehicle speed, atmospheric pressure, engine net output torque, friction torque, engine speed, engine fuel flow, output value of the NOx sensor (nitrogen oxygen sensor) upstream of SCR (selective catalytic reduction technology), output value of the NOx sensor downstream of SCR, reactant balance, intake air volume, SCR inlet temperature, SCR outlet temperature, DPF (wall flow particulate filter) pressure difference, engine coolant temperature, fuel tank level, positioning status, latitude and longitude, and cumulative mileage. (2) The operating status data uploaded by the on-board terminal of non-road machinery includes vehicle speed, atmospheric pressure, diesel engine output torque, friction torque, diesel engine speed, output value of the NOx sensor upstream of SCR, output value of the NOx sensor downstream of SCR, reactant balance, intake air volume, SCR inlet temperature, SCR outlet temperature, DPF pressure difference, diesel engine coolant temperature, fuel tank level, actual EGR (exhaust gas recirculation valve) opening, set EGR opening, and latitude and longitude.

[0004] In addition, the on-board terminals of heavy-duty diesel vehicles and off-road machinery must also upload terminal data such as: emission control diagnostic protocol, emission control warning light status, total number of emission control fault codes, and emission control fault code information list.

[0005] After data from vehicle-mounted terminals on heavy-duty diesel vehicles and off-road machinery is uploaded to the national environmental data platform, the platform performs data cleaning (i.e., invalid data filtering). If the proportion of invalid data exceeds a certain limit, the uploaded data is deemed abnormal. Abnormal patterns include: data packet loss, abnormal data rationality, abnormal data correlation, and data with fixed values ​​or regular repetitive transmission. These abnormal patterns affect the calculation results of the data platform's algorithm, and this behavior is defined as data tampering (i.e., data inconsistency), which is part of the supervision and governance for illegal correction.

[0006] Meanwhile, the environmental data platform performs algorithmic analysis on the data uploaded by the vehicle-mounted terminal. On the one hand, by modeling and analyzing the engine operation and emissions through the uploaded data from the engine and emission sensors, it obtains the actual operating conditions and emission characteristics of mobile sources (i.e., mobile air pollution sources, also called mobile pollution sources, such as heavy-duty diesel vehicles and non-road machinery). On the other hand, by comparing and evaluating the engine status, the monitoring status of key emission components, and the abnormal status of the OBD system (i.e., on-board automatic diagnostic system), it obtains the evaluation conclusion of the OBD system monitoring function, thereby obtaining the conclusion of the abnormal judgment of the OBD system (i.e., on-board automatic diagnostic system).

[0007] Based on the algorithms and violation clues of the aforementioned environmental data platform, violation clues can be categorized into: emission-related, OBD function-related, and data quality-related.

[0008] Currently, in order to achieve the goal of closed-loop management of identification, judgment and control of mobile pollution sources, it is necessary to conduct on-site testing and confirmation of violation clues obtained from the environmental data platform to realize closed-loop control.

[0009] However, there is currently no technology that can conduct closed-loop on-site testing to confirm the violation clues obtained by the environmental data platform, thereby enabling the environmental data platform to effectively control mobile pollution sources and achieve closed-loop governance. Summary of the Invention

[0010] The purpose of this invention is to address the technical deficiencies of existing technologies by providing a mobile source on-site law enforcement device that integrates an environmental data platform.

[0011] Therefore, the present invention provides a mobile source on-site law enforcement device that integrates an environmental protection data platform, which includes a communication module and a testing module;

[0012] The communication module wirelessly communicates with the environmental data platform to receive clues about suspected illegal vehicles sent by the existing environmental data platform. Then, based on the vehicle location information in the clues about suspected illegal vehicles, it locates the suspected illegal vehicles and alerts law enforcement officers. At the same time, it alerts law enforcement officers to conduct on-site verification of the suspected illegal vehicles based on the vehicle identification number in the clues about suspected illegal vehicles.

[0013] The testing module, which is connected to the communication module, is used to conduct compliance tests on suspected vehicles based on the violation category information in the clue information of suspected vehicles sent by the communication module when law enforcement officers conduct on-site verification of suspected vehicles. The on-site test results are then sent to the communication module.

[0014] The communication module is also used to receive the on-site test results sent by the test module and then upload them to the environmental protection data platform to achieve closed-loop supervision.

[0015] Among them, the environmental protection data platform is used to receive the operating status data wirelessly uploaded by all vehicle terminals, identify and determine the suspected illegal vehicles with clues of violations, and then send the clue information of the suspected illegal vehicles to the communication module of the mobile source on-site law enforcement equipment.

[0016] Information on suspected violations includes: vehicle identification number, vehicle location information, and violation category.

[0017] Preferably, the communication module is specifically used to locate the suspected illegal vehicle on an electronic map based on the vehicle location information in the clue information of the suspected illegal vehicle.

After the test, the OBD function test results of the suspected non-compliant vehicles are uploaded to the environmental protection data platform through the communication module.

[0030] Preferably, the testing module performs on-board terminal data consistency testing on suspected non-compliant vehicles, specifically including the following operations:

[0031] The testing module is used to establish a data connection with the vehicle terminal (i.e., T-BOX) of the suspected violating vehicle, and then send standard template information to the vehicle terminal of the suspected violating vehicle.

[0032] The vehicle's onboard terminal, which is suspected of being in violation of regulations, is used to upload standard template information to the environmental data platform in real time after receiving the standard template information.

[0033] At this time, the environmental data platform is used to receive standard template information uploaded by the on-board terminals of vehicles suspected of violating regulations;

[0034] The testing module is also used to download the standard template information uploaded by the vehicle terminal of the suspected non-compliant vehicle from the environmental protection data platform through the communication module, and then compare the standard template information uploaded by the vehicle terminal of the suspected non-compliant vehicle with the standard template information originally sent to the vehicle terminal of the suspected non-compliant vehicle to obtain the data consistency test result of the vehicle terminal of the suspected non-compliant vehicle, and then upload the test result to the environmental protection data platform through the communication module.

[0035] Preferably, standard template information includes OBD diagnostic data and / or engine data stream;

[0036] To obtain OBD diagnostic data, the following steps are specifically included:

[0037] The test module establishes a data connection with the ECU of the suspected violating vehicle, and then sends an OBD diagnostic request to the ECU of the suspected violating vehicle.

[0038] The ECU of a suspected non-compliant vehicle returns OBD diagnostic data to the test module upon request.

[0045] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] See Figures 1 to 4 This invention provides a mobile source on-site law enforcement device that integrates an environmental data platform. It is an on-site law enforcement device for mobile sources (i.e., mobile air pollution sources, which are pollution sources whose location can be moved), and includes a communication module and a testing module.

[0049] The communication module communicates wirelessly with the environmental data platform (e.g., 5G or 4G wireless communication) to receive clues about suspected illegal vehicles sent by the existing environmental data platform. Then, based on the vehicle location information in the clues about suspected illegal vehicles, it locates the suspected illegal vehicles (specifically, the location of the suspected illegal vehicles can be located on an electronic map) and alerts law enforcement personnel. At the same time, it alerts law enforcement personnel to conduct on-site verification of the suspected illegal vehicles based on the vehicle identification number in the clues about suspected illegal vehicles.

[0050] The testing module, which is connected to the communication module, is used to conduct compliance tests on suspected vehicles based on the violation category information in the clue information of suspected vehicles sent by the communication module when law enforcement officers conduct on-site verification of suspected vehicles. The on-site test results are then sent to the communication module.

[0051] The communication module is also used to receive the on-site test results sent by the test module and then upload them to the environmental protection data platform to achieve closed-loop supervision.

[0052] Among them, the environmental protection data platform is used to receive the operating status data uploaded (wirelessly uploaded) by all vehicle terminals, identify and determine the suspected illegal vehicles with clues of violations, and then send the clue information of the suspected illegal vehicles to the communication module of the mobile source on-site law enforcement equipment.

[0053] Information on suspected violations includes: vehicle identification number (including license plate number, engine number, etc.), vehicle location information (i.e., location information), and violation type (i.e., violation pattern).

[0054] It should be noted that the violation clue categories (i.e. violation patterns) can specifically include at least one of the following: emission-related (including smoke emission and nitrogen oxide emission), OBD function-related, and data quality-related violation clues.

[0055] It should be noted that, according to the requirements of the "Emission Limits and Measurement Methods for Pollutants from Heavy-Duty Diesel Vehicles (China VI) (National Standard GB 17691-2018)" and the "Technical Requirements for Pollutant Emission Control of Non-Road Diesel Mobile Machinery (Environmental Standard HJ1014-2020)," heavy-duty diesel vehicles and non-road diesel mobile machinery must be equipped with on-board terminals. These on-board terminals (specifically, the OBD system) upload engine and vehicle (engine) operating status data in real time to the environmental data platform via a wireless network (e.g., 4G or 5G communication network) (see the background section above for details). They also upload vehicle location information, OBD (On-Board Diagnostic) information and status, and vehicle location information. After receiving the data uploaded by the on-board terminals, the environmental data platform evaluates the quality and consistency of the uploaded data and performs data cleaning and screening. The filtered data is then processed using algorithms and compared with the limits specified in current environmental standards to determine potential violations and identify suspected non-compliant vehicles. As mentioned earlier, the specific methods and algorithms used are well-known and mature technologies in existing environmental data platforms, and will not be elaborated upon here.

[0056] In practice, the environmental data platform adopts a grid-based environmental supervision model, which sends clues about suspected illegal vehicles, such as violation categories (i.e. violation patterns), vehicle identification information, and location information, to the communication module in the mobile source on-site law enforcement equipment via the 5G network in TCP / IP communication format.

[0057] In specific implementation, the environmental data platform refers to the existing environmental data platforms established by relevant national departments. For example, it could be the Beijing Mobile Source Emission Remote Online Monitoring Integrated Platform established by the Beijing Municipal Bureau of Ecology and Environment. This platform can achieve vehicle information reception and vehicle positioning functions for heavy-duty vehicles registered in Beijing that meet the National V and National VI emission standards through algorithms. It can also determine whether the data consistency function meets regulatory requirements through data quality evaluation algorithms, whether the vehicle emissions meet regulatory limits through nitrogen oxide algorithms, whether the excess air coefficient meets smoke opacity regulatory limits through intake air volume and fuel injection volume algorithms, and whether the vehicle's OBD function meets regulatory requirements through OBD function algorithms. The platform will then push the identified violation clues and vehicle positioning information to the enforcement terminal (such as the mobile source on-site enforcement equipment of this invention) to guide the enforcement terminal in locating suspected non-compliant vehicles and determining the vehicle verification items.

[0058] In this invention, specifically, the communication module, based on the vehicle location information in the clue information of the suspected illegal vehicle, after locking the location of the suspected illegal vehicle (specifically, the location of the suspected illegal vehicle can be locked on an electronic map), is also used to navigate to the location of the suspected illegal vehicle (i.e., the target location), providing law enforcement officers with navigation planning routes (specifically, this function can be implemented based on existing electronic map software), and providing law enforcement officers with navigation tracking functions.

[0059] In this invention, specifically, the testing module performs compliance tests on suspected non-compliant vehicles based on the violation category information in the clue information of suspected non-compliant vehicles sent by the environmental data platform, as follows:

[0060] When the violation category information of the suspected vehicle is nitrogen oxide emission violation information, a nitrogen oxide emission compliance test will be conducted on the suspected vehicle.

[0061] When the violation category information of the suspected vehicle is smoke emission violation information, a free acceleration smoke emission compliance test will be conducted on the suspected vehicle.

[0062] When the violation category information in the clue information of a suspected violation vehicle is OBD function violation information, an OBD function compliance test is conducted on the suspected violation vehicle.

[0063] When the violation category information of a suspected violating vehicle is data quality violation information, a data consistency test of the vehicle terminal is conducted on the suspected violating vehicle.

[0064] The four compliance tests mentioned above are explained in detail below:

[0065] First, the testing module conducts nitrogen oxide emission compliance tests on suspected non-compliant vehicles, specifically including the following operations:

[0066] The testing module is used to conduct nitrogen oxide emission tests on suspected non-compliant vehicles in accordance with existing national document requirements and the testing specifications stipulated in the national documents. After the test, the nitrogen oxide emission test results of the suspected non-compliant vehicles are uploaded to the environmental protection data platform through the communication module.

[0067] It should be noted that, in order to realize the nitrogen oxide emission testing function, the testing module may specifically include existing and known nitrogen oxide detectors, and perform this function in a specific way.

[0068] It should be noted that nitrogen oxide emission testing for suspected non-compliant vehicles can be conducted according to the nitrogen oxide testing methods and limits specified in the document "Rapid Detection Methods and Emission Limits for Nitrogen Oxides from Heavy-Duty Vehicles" (Beijing Municipal Bureau of Ecology and Environment DB11 1476-2018), using the dynamic 30-second moving average transient emission result testing method specified in the document, for on-site testing and result evaluation. This is a well-known existing technology and will not be elaborated upon here.

[0069] Second, the testing module conducts a free acceleration smoke emission compliance test on suspected non-compliant vehicles, specifically including the following operations:

[0070] The testing module is used to conduct free acceleration smoke emission tests on suspected non-compliant vehicles in accordance with existing national document requirements and the testing specifications stipulated in the national documents. After the test, the free acceleration smoke emission test results of the suspected non-compliant vehicles are uploaded to the environmental protection data platform through the communication module.

[0071] It should be noted that, in order to realize the free acceleration smoke emission test function, the test module may specifically include the existing known opacity meter, and the opacity meter is used to perform this function.

[0072] It should be noted that the free acceleration smoke test for suspected non-compliant vehicles can be conducted according to the test method and limit requirements for free acceleration smoke in GB3847-2018 "Limits and Measurement Methods for Pollutant Emissions from Diesel Vehicles (Free Acceleration Method and Loaded Deceleration Method)," using the opaque smoke test method to conduct on-site testing and result evaluation of suspected non-compliant vehicles. This is a well-known existing technology and will not be elaborated upon here.

[0073] Third, the testing module performs OBD function compliance testing on vehicles suspected of violating regulations, specifically including the following operations:

[0074] The testing module is used to conduct OBD function tests on suspected non-compliant vehicles in accordance with existing national document requirements and testing specifications stipulated in the national documents. After the test, the OBD function test results of the suspected non-compliant vehicles are uploaded to the environmental protection data platform through the communication module.

[0075] It should be noted that OBD function testing for suspected non-compliant vehicles can be conducted according to the basic OBD function requirements for heavy-duty vehicles in stages 5 and 6 as specified in "HJ437-2008 - Technical Requirements for Engine and Automobile On-Board Diagnostic (OBD) Systems" and "Emission Limits and Measurement Methods for Pollutants from Heavy-Duty Diesel Vehicles (China Stage VI) (GB 17691-2018)". On-site testing can be performed according to the testing specifications stipulated in these two national documents. This is a well-known existing technology and will not be elaborated upon here.

[0076] Fourth, the testing module performs on-board terminal data consistency testing on suspected non-compliant vehicles, specifically including the following operations:

[0077] The testing module is used to establish a data connection with the vehicle terminal (i.e., T-BOX) of the suspected violating vehicle, and then send standard template information to the vehicle terminal of the suspected violating vehicle.

[0078] The vehicle's onboard terminal, which is suspected of being in violation of regulations, is used to upload standard template information to the environmental data platform in real time after receiving the standard template information.

[0079] At this time, the environmental data platform is used to receive standard template information uploaded by the on-board terminals of vehicles suspected of violating regulations;

[0080] The testing module is also used to download standard template information uploaded by the on-board terminal of the suspected violating vehicle from the environmental data platform via the communication module (the download can be based on the vehicle identification number of the suspected violating vehicle). Then, it compares the standard template information uploaded by the on-board terminal of the suspected violating vehicle with the standard template information initially sent to the on-board terminal of the suspected violating vehicle to obtain a data consistency test result for the on-board terminal of the suspected violating vehicle. This test result is then uploaded to the environmental data platform via the communication module. Specifically, if the two sets of information are inconsistent, it is determined that the on-board terminal of the suspected violating vehicle has a data inconsistency problem; if the two sets of information are consistent, it is determined that the on-board terminal of the suspected violating vehicle does not have a data inconsistency problem.

[0081] It should be noted that the on-board terminal data consistency testing technology proposed in this invention meets the data consistency testing requirements for on-board terminals in the "Emission Limits and Measurement Methods for Pollutants from Heavy-Duty Diesel Vehicles (China VI) (National Standard GB17691-2018)".

[0082] In terms of specific implementation, the standard template information includes OBD diagnostic data and / or engine data stream;

[0083] To obtain OBD diagnostic data, the following steps are specifically included:

[0084] The test module establishes a data connection with the ECU of the suspected violating vehicle, and then sends an OBD diagnostic request to the ECU (Electronic Control Unit) of the suspected violating vehicle.

[0085] The ECU of a suspected non-compliant vehicle returns OBD diagnostic data to the test module upon request.

[0086] In terms of specific implementation, it should be noted that the testing module is specifically used to send OBD diagnostic data to the on-board terminal of the suspected non-compliant vehicle only after receiving an OBD diagnostic request from the on-board terminal (i.e., T-BOX) of the suspected non-compliant vehicle.

[0087] It should be noted that when the standard template information is OBD diagnostic data, the test module acts as a diagnostic tool; when the standard template information is engine data stream, the test module acts as a diagnostic tool.

[0088] It should be noted that the engine data stream, specifically the 16 engine data streams stipulated in existing national documents, is publicly known information and will not be elaborated upon here.

[0089] It should be noted that, in terms of specific implementation, the communication module can be an existing computing device with 5G or 4G communication capabilities (such as a laptop or tablet).

[0090] It should be noted that the development and application of the mobile source on-site law enforcement equipment provided by this invention can meet the environmental data testing and law enforcement requirements under the new national standard documents, and realize on-site confirmation and closed-loop management of violation clues.

[0091] It should be noted that the mobile source on-site enforcement equipment provided by this invention, which integrates with the environmental protection data platform, is mainly used to track and verify on-site violations of mobile sources (heavy-duty diesel vehicles or non-road machinery) that have been identified by the environmental protection data platform as having excessive emissions or malfunctioning OBD monitoring functions. Furthermore, it conducts on-site verification of the data transmission consistency of the remote monitoring system for heavy-duty diesel vehicles or non-road machinery as required by the "Emission Limits and Measurement Methods for Pollutants from Heavy-Duty Diesel Vehicles (China VI) (GB 17691-2018)" and the "Technical Requirements for Pollutant Emission Control of Non-Road Diesel Mobile Machinery (Environmental Standard HJ 1014-2020)". It also verifies on-site violations of smoke opacity, nitrogen oxide emissions, and OBD function of the heavy-duty diesel vehicles or non-road machinery, thus meeting the closed-loop on-site enforcement verification requirements of the environmental protection data platform.

[0092] To better understand the technical solution of the present invention, a specific embodiment is described below. Figures 2 to 4 The overall working process of the present invention will be illustrated as shown below.

[0093] Step 1: The environmental data platform receives data transmitted by all heavy-duty diesel vehicles through their on-board terminals. Using existing algorithms on the environmental data platform, it statistically analyzes and identifies suspected non-compliant vehicles.

[0094] Step 2: The environmental data platform sends the clues of suspected illegal vehicles to the on-site law enforcement equipment (specifically the communication module). The clues of suspected illegal vehicles include: vehicle identification number, vehicle location, and violation type (i.e., violation pattern).

[0095] Step 3: After receiving the violation clues transmitted by the environmental protection data platform, the on-site enforcement equipment locates the suspected violation vehicle based on the vehicle's location information and prompts enforcement personnel to conduct on-site verification.

[0096] Step 4: Law enforcement officers will verify the violation clues based on the violation categories (i.e. violation patterns). For violation patterns of excessive nitrogen oxides and excessive free acceleration smoke, tests will be conducted in accordance with the testing procedures required by relevant national documents.

[0097] Step 5: For vehicles suspected of violating regulations and exhibiting OBD violation mode, connect the on-site enforcement equipment to the vehicle's CAN network and follow the equipment prompts to perform testing operations in accordance with the requirements of relevant national documents.

[0098] Step Six: For suspected violations involving inconsistent onboard terminal data, law enforcement officers connect the on-site enforcement equipment (specifically via its CAN card) to the vehicle's CAN network. First, the vehicle is powered on. Using a host computer, the on-site enforcement equipment connects to the vehicle's CAN network via a diagnostic node. It reads ECU characteristic information (specifically ODB diagnostic data) from the vehicle's ECU and then disconnects the power. The onboard terminal of the suspected vehicle is then disconnected, and power is supplied to the on-site enforcement equipment. The equipment connects to the ODB system via the ECU node and responds to the onboard terminal (specifically the ODB system) with ECU characteristic information. After normal communication, the ECU characteristic information (specifically ODB diagnostic data) or engine data stream information is broadcast as a standard template to the onboard terminal. The onboard terminal uploads the data (i.e., the standard template information) to the environmental data platform. The on-site enforcement equipment then downloads the corresponding data (i.e., the original data) from the environmental data platform and compares it with the initially sent standard template information for data consistency. For details, please refer to [link to relevant documentation]. Figure 4 The test procedure is shown below.

[0099] For example, see Figure 3 As shown, the on-site enforcement equipment 6 is connected to the ECU of the suspected violating vehicle 9 and the vehicle terminal 8 via CAN card 7. The on-site enforcement equipment 6 communicates wirelessly with the environmental protection data platform 5, and the environmental protection data platform 5 communicates wirelessly with the vehicle terminal 8 via signal base station 10.

[0100] It should be noted that when the standard template information is OBD diagnostic data, the test module acts as a diagnostic tool, and in this case, the OBD diagnostic data collected from the vehicle's ECU can be stored.

[0101] Step 7: After obtaining on-site test results indicating violations, the on-site enforcement equipment will issue test result notices to suspected violating vehicles on-site, based on relevant regulatory limits and functional requirements, and upload the test results to the environmental data platform for closed-loop supervision.

[0102] It should be noted that, for the present invention, when conducting specific on-site law enforcement operations, before the test is carried out, the on-site law enforcement personnel need to verify the characteristics and vehicle identification number of the test object (i.e., the suspected illegal vehicle), and input key information such as the fuel type and emission stage of the test object (i.e., the suspected illegal vehicle) into the on-site law enforcement equipment in accordance with the requirements of existing national documents.

[0103] Compared with existing technologies, the mobile source on-site law enforcement equipment integrated with an environmental data platform provided by this invention has the following beneficial effects:

[0104] This invention addresses the current situation where environmental data platforms receive vehicle-mounted terminal data and analyze it to obtain clues of violations, but lack sufficient on-site enforcement methods. It enables precise location and accurate measurement of mobile source emissions, allowing law enforcement personnel to verify on-site vehicle violation clues and issue test results. This fills a gap in the field and realizes the environmental management requirements of big data closed-loop governance.

[0105] In summary, compared with existing technologies, the mobile source on-site enforcement device integrated with an environmental protection data platform provided by this invention is scientifically designed and can conduct closed-loop on-site testing and confirmation of violation clues obtained from the environmental protection data platform, thereby realizing the effective control of mobile pollution sources by the environmental protection data platform and achieving closed-loop governance, which has significant practical significance.

[0106] By applying this invention, it is possible to locate, track, and conduct on-site testing of violation clues obtained from environmental data platforms, thereby filling the current gap in closed-loop management equipment and meeting testing and law enforcement needs.

[0107] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
