With the rapid development of my country’s automobile industry, we are also facing tremendous pressure brought by the automobile industry: environmental protection issues. With the deteriorating environmental quality, environmental protection has become a focal issue of common concern for the whole society.
In order to reduce vehicle exhaust emissions and rectify air pollution, the government has issued a series of policies and regulations. For example, more than a dozen exhaust gas detection stations have been set up in major urban areas of Beijing to carry out exhaust gas detection on vehicles currently in use, and remediate, investigate and even force scrapping of all vehicles that do not comply with exhaust emission regulations. However, in the process of exhaust gas detection and supervision, how the government adopts scientific and advanced methods to provide reasonable and efficient services and management is a question worthy of discussion.
Problems encountered in exhaust gas treatment
In the exhaust gas treatment process, there are two links that are very important. One is how to use scientific and effective methods to accurately and quickly detect each car in the exhaust gas detection field, and record the detection parameters and detection time in real time. Law enforcement agencies provide evidence of supervision, and at the same time provide automobile quality supervision agencies with inspection statistics for each vehicle type. These statistics are very precious to law enforcement agencies and auto manufacturers; the second is how law enforcement agencies can effectively supervise the control of automobile exhaust. Ultimately realize the fundamental purpose of environmental governance.If you take a walk to the United States, you will find that they have adopted many advanced and effective methods in exhaust gas detection and supervision. These are what my country can learn and learn from. One of the technologies is the use ofPDF417Two-dimensional barcode technology. The following briefly introduces the application of the new automatic identification technology of Nankai Gode’s two-dimensional barcode in exhaust gas detection and supervision that the government is more concerned about.
Nankai Gode QR Code – Perfect solution
QR codePDF417The information capacity is large, the information density is high, and the coding ability is strong. It can encode photos, text, fingerprints, palmprints, voices, signatures and other information, and it is easy to print, low cost, strong error correction ability, and high decoding reliability . It is precisely because the two-dimensional barcode can realize the two important functions of machine reading and anti-counterfeiting, therefore, internationally,PDF417Bar codes are widely used in document management, vehicle management, logistics and warehouse management.In our country, the first two-dimensional barcode national standard “4-17 Barcode” was established in1997year12Officially promulgated in December, it markedPDF417The application of bar codes in our country is entering a formal and orderly development stage.
Relying on the technical strength of Nankai University, Nankai Gold has established its own irreplaceable advantages in the field of 2D barcodes with its own technical advantages: hardware: owns the only production base of 2D barcode readers in the Asia-Pacific region; software, haveGDDigital encryption technology, first-class system analysis engineer, first-class software design engineer. Nankai Gode’s two-dimensional barcode solution with its own characteristics will perfectly solve your problem.
Exhaust gas detectionPDF417
In the United States, if you go to Arizona (Arizona),Colorado(Colorado),Delaware(Delaware),New York state(New York),Pennsylvania(Pennsylvania),Virginia(Virginia) For exhaust gas detection in other places, you will be surprised by the fast, accurate and efficient work here.from1997Beginning in the year, all vehicles must be pastedPDF417The exhaust gas detection tag is used to record the parameters of the car and the detection parameters.In 1997, a total of nearly8,000towerSymbolProduced by the companyLS4804Equipment for readingPDF417.
The workflow of the entire inspection site is as follows:
The advantages of using Nankai Gode QR code
Used in exhaust gas detectionPDF417Can bring many benefits:
Can realize high-efficiency operation.In the inspection station, each car will have a lot of data to be copied, which requires a lot of time and manpower, such as the use ofPDF417, All the data that must be copied repeatedly in the test, including the car engine number, license plate number, and the last test parameters, etc., are all stored inPDF417, The staff only needs to scan with the scanner, and the required data is less than1All enter the computer within seconds, greatly improving work efficiency. Data entry is automated.
The supervision of law enforcement agencies can be strengthened. As a sign of whether a car can be legally used on the road, the exhaust gas detection label is a prerequisite for the annual car inspection in many states in the United States. Only cars that pass the exhaust gas detection may receive a car permit.becausePDF417It is a portable data file that can store a large amount of information, and it has strong anti-counterfeiting ability and is not easy to forge. Therefore, the data carried by the exhaust gas detection tag is convenient for law enforcement officers to read anytime and anywhere on the road, strengthening the supervision of law enforcement agencies Intensity.
Can provide precious statistical data for relevant departments. The test data obtained at the test site can be directly transmitted to the central database through the network, providing law enforcement agencies and environmental supervision agencies with fast and accurate parameters and statistical data, so that the government can adjust guidelines and policies in a timely manner.
Small investment, quick results, can make upEDIAnd the lack of network construction. At present, my country’s network construction still cannot meet the needs of practical applications, and the network construction investment is large and the cost is high.andPDF417Two-dimensional barcode is a kind of paperEDI, It has no requirements on the network, and the functions of data storage, transmission and automatic identification can be easily realized through a piece of label paper, and the investment is very low, which can make up for it well.EDIAnd the lack of network construction.
Can reduce the burden on the network.In the United States, where network construction is very developed, why still choosePDF417As a carrier for carrying data?The reason is that although each exhaust gas detection station has a remote network connected to the central database, the network may be disconnected or congested, so it is adoptedPDF417As a carrier of information, it can quickly and accurately realize the data acquisition function of the network. After all vehicles have been detected, it can communicate with the central database during off-duty hours, thus avoiding network congestion and providing customers with accurate and timely services.
Today’s Beijing city,“Calling for blue sky and white clouds“It has become the common wish of all people who love Beijing. Although this article introduces the application of a new technology in exhaust gas detection and supervision, it is essentially an introduction to a new foreign management model. Only by adopting as perfect, practical and advanced supervision and management model as possible in our country, and plugging loopholes as much as possible, can we really improve our country’s ecological environment, raise the awareness of environmental protection of every citizen, and usher in the sky of Beijing Walan again.
