The sudden explosion at a high-speed intersection a few days ago was very worrying and uncomfortable.

According to an official report, at 16:46 on June 13, at the middle of the on-ramp ramp of the Wenling exit of Taizhou, Zhejiang, Shenhai Expressway, an liquefied gas tanker from Ningbo to Wenzhou exploded, and the exploding tanker smashed to the side of the road.There was a second explosion in a factory building.As of 7 o’clock on June 15, the explosion caused a total of 20 deaths and more than 170 people were hospitalized.
The specific cause of the accident has not yet been determined, and the traffic police initially confirmed that the explosion was a single-vehicle accident in the Wenling tank truck.Some professionals speculate that it is likely that the driver of the tank truck was too fast when passing the ramp and collided with the ramp guardrail, resulting in leakage of liquefied gas and explosion in the event of an open flame.This type of LPG liquefied gas has a low explosion limit and high explosion power.Even more unfortunately, the high-speed ramp at the accident site is very close to the factory residential area, so it is very regrettable to cause such huge casualties.
In fact, we often see such accidents or explosions in the transportation of dangerous goods vehicles in the news.Experienced veteran drivers know that if they encounter such tankers on the highway, they will consciously stay away or accelerate.When you encounter a high-speed ramp, try to keep the distance.
Every time such an accident occurs, all we seem to be able to do is mourn or be indifferent on social media.However, we should go deeper into the specific process links of this kind of dangerous goods transportation and try to use new technologies to improve the weakness of this industry chain.Blockchain technology may become a solution to the safe transportation of dangerous goods.
Technical Reengineering of Dangerous Goods Transportation Process
After the explosion accident of the Wenling tanker truck, we can see that the traffic control departments and safety emergency departments in various places are making voices one after another, and put forward the precautions and solutions for the transportation of dangerous goods and traffic safety management.
The most basic idea is to continuously emphasize the safety precautions for the transportation of dangerous goods from the management process.For example, like strengthening the inspection of dangerous chemical transportation vehicles to prevent vehicles from getting “on the road”; strengthening cargo handling regulations, vehicle escorts should make detailed records of the cargo situation in order to deal with emergencies at any time; strengthen the safety regulations of transportation drivers,Including strict compliance with traffic laws, reasonable arrangement of driving time, etc.; and strengthening the emergency response capability of dangerous goods, capable of timely disposal after leakage and other situations, such as timely evacuation after failure, alarm and organization of evacuation of vehicles around.
These precautions are themselves the daily safety regulations of the dangerous goods transportation industry. They are emphasized only after an accident. There is still a problem of hindsight.
System regulations always require specific carrier companies and specific people to implement, and as long as there are people, there are paralyzed security risks, so security precautions need technical support.There are already a large number of in-vehicle networking technologies to ensure the safe management of dangerous goods transportation vehicles.
In order to ensure the safety of the entire dangerous goods transportation process, comprehensive, timely, accurate, and reliable information supervision and control of transportation vehicles and personnel are required.
At present, the application of intelligent vehicle terminals, through radio frequency technology (RFID), satellite positioning (GPS), OBD and other technologies, can provide technical support for the tracking, monitoring and management of dangerous goods logistics processes, and provide emergency management after accidentsProvide technical support.
In the management of drivers, the identification of the driver and the status of driving behavior can be tracked in real time through identity recognition technology and on-board cameras to achieve efficient management and performance evaluation of drivers.
In the monitoring of transportation vehicles and dangerous goods, the vehicle’s driving status, vehicle condition information, and dangerous goods status (whether there are leaks, theft, or temperature and pressure changes) can be real-time real-time through the vehicle’s outdoor camera, vehicle OBD port and sensormonitor.
In locating transportation vehicles, you can use GNSS to accurately locate vehicle location information, track vehicle positions, optimize route planning, and estimate transportation time, etc., to accurately improve the operational efficiency of transportation fleets.
For emergency incident alarm, the alarm device of the smart vehicle terminal can also be used to automatically send the distress information together with the accident-related information to the alarm center after activation.Losses caused by accidents.
The intelligent vehicle-mounted system not only helps transportation companies to realize real-time dynamic security monitoring of people, vehicles, and goods, but also provides a technical foundation for the entire transportation fleet to achieve network and digitalization.
This is significant because the dangerous goods transportation industry is a very special service industry. In addition to these detailed safety control technologies, the introduction of blockchain technology will also bring more industrial digital capabilities.
Blockchain, the basis of digitalization of dangerous goods transportation process
Blockchain technology is a new opportunity that can help the dangerous goods transportation industry to carry out overall management and operation upgrades.As we all know, blockchain is famous for cryptocurrencies such as Bitcoin and Ethereum. This technology combines distributed data storage technology and advanced encryption functions to record transactions, thereby protecting transactions from malicious revision or deletion.The resulting data generates a high degree of trust and can ultimately drive related transactions, the most important of which is the introduction of the concept of “smart contracts”.
Therefore, not only in the field of cryptocurrency, blockchain has been widely used in finance, insurance, certification contracts, transportation, logistics and other fields. Among them, for the logistics industry, the scope and depth of its technical application has been widely recognized by the industry.
On the one hand, blockchain can enhance trust and transparency in the logistics industry and directly reduce the cost of communication in cargo transportation.It should be known that the communication documents and verification costs in the logistics process only account for one fifth of the cost of transporting goods.
On the one hand, blockchain can improve the safety and efficiency of the entire transportation process.Especially for ocean-going container transportation, a large number of shipping accidents are caused by incorrect declaration of goods and improper shipments causing fire, pollution and other transportation safety problems and cargo mismatch and wrong transportation problems.How the introduction of digital tools including blockchain and sensor chips can improve the traceability of dangerous goods, and improve transparency and accountability to help solve this problem.
Due to the high risk and high profitability, but once the accident occurs, the loss of the industry is particularly serious. Dangerous goods transportation has become a very special existence in the logistics industry.The traceable and traceable characteristics of the blockchain will directly help transportation companies and upstream companies, carrier fleets, traffic control, security supervision departments and financial and insurance companies to establish a transparent and reliable “digital contract”.The entire transportation process has achieved digital management of the entire industry chain such as process data, clarification of responsibility subjects and responsibility traceability.
Specifically, with the help of blockchain technology, the following digital management of the entire process of dangerous goods transportation can be achieved.
1. Help upstream enterprises to distribute transportation capacity.Based on the on-chain data of transportation companies that carry dangerous goods, upstream companies can accurately learn about the use and idleness of vehicles, which can optimize the configuration of vehicles and improve transportation efficiency.
2. Help the fleet achieve safe transportation management.By uploading vehicle safety information and driver behavior data information, you can establish a complete vehicle safety evaluation system and driver safety scoring system certification, especially for drivers to establish a credible safety and integrity scoring system to integrate their daily behavior andThe future career prospects will greatly avoid the driver’s irregular operation and the driver’s concealment of the accident and then job search.
3. Help to condemn vehicle traffic accidents.The combination of blockchain technology and in-vehicle intelligent system can be used to compare vehicle video evidence with traffic department video evidence and other multi-party data to faithfully restore the driver’s condition and driving condition in traffic accidents, effectively determine accident liability and insurance compensationIdentify.
In addition to helping transportation companies do a good job of digital management certification in the process of dangerous goods transportation to improve transportation efficiency, reduce transportation accidents and liability identification issues, blockchain technology can also improve the overall operation level of transportation enterprises and the entire industry.Enhance the scale and anti-risk capabilities of the industry.
New technology for the overall upgrading of the industry
We can first look at the overall characteristics of the dangerous goods transportation industry.In 2018, my country’s transportation of dangerous goods was about 1.86 billion tons, of which more than 50% was transported by road, with a market size of about 1.47 trillion yuan.As of June 2018, there were more than 11,500 enterprises engaged in the transportation of dangerous goods on roads, with approximately 1.506 million employees, including more than 700,000 drivers of dangerous goods vehicles.There are more than 373,000 special vehicles for the transportation of dangerous goods, mainly in the form of tank trucks and vans.
Due to the uneven distribution of production and sales of more than 5,000 kinds of chemical raw materials in my country, more than 95% of them need to be transported in different places. The “separation of production and sales” determines the tight transportation of “hazardous logistics”.From the point of view of the structure of dangerous goods transportation enterprises, the industry is mainly dominated by small and medium-sized enterprises, and the scale of enterprises is small. The above-scale enterprises have higher competitive advantages in the industry and have obvious regional characteristics.
On the one hand, the surge in demand for dangerous goods transportation has led to rapid growth of dangerous goods transportation companies; on the other hand, due to the frequent occurrence of dangerous goods transportation accidents, the pressure of government supervision has increased, and there have been a large number of qualification audits while the transportation companies have grown orEnterprises with insufficient strength are cancelled or their operating qualifications are revoked.
Some of the problems are that the weak fleets are anchored under qualified transportation companies to carry out the actual transportation of dangerous goods. Among them are illegal conversions, insufficient maintenance, and weak safety awareness of carriers and drivers.The fierce competition in the entire industry has also led to low-price bidding, and then through some illegal and illegal transportation, compressing costs to profit.
For example, according to media verification, in the Wenling explosion accident, the industrial and commercial registration information showed that the company in question had received 11 administrative penalties for failure to conduct vehicle comprehensive performance testing and technical grade assessment according to the prescribed cycle and frequency.However, these administrative penalties have not received the attention of the companies involved, nor have they been effectively reviewed by the shipping customers.
Behind the problem is the fundamental reason that restricts the development of the industry, that is, it is difficult for dangerous goods transportation companies to obtain continuous credit support from bank financial institutions, and it is difficult to achieve stable scale growth, so that those companies with strong qualifications, good reputation, and good management can be enlarged.Be strong.
Due to the huge capital turnover demand for dangerous goods transportation, non-core SMEs have difficulties in financing and expensive financing due to low digital informatization and low value of collateral. It is difficult to obtain bank credit and insurance companies’Preferential policies.
As we introduced above, through the data collection of the onboard intelligent system of the transportation vehicle and the storage and authentication of the blockchain data, it will effectively ensure that the transportation company’s business situation, transportation process and safety management measures are transparent and true, and the data can be traced and quantified, Which can form an effective and assessable credit asset.On the one hand, it can help companies to apply for financial loans through effective contracts, on the one hand, it can help banks better control credit risk and high-quality data collection of insurance.
Since blockchain technology can guarantee the updating of operational data and cross-validation of data sources, real-time monitoring and evaluation can be achieved in terms of credit, credit, loan use, and repayment capabilities, thereby effectively guaranteeing the safety of funds.
Relying on blockchain technology, those dangerous goods transportation companies that standardize operations, strictly control transportation safety, and strictly control costs will obviously obtain the enabling value brought by technology, thereby obtaining business support from the entire industry chain and from regulatory authorities, banking and insurance industries.Credit support, and this is the fundamental way for the dangerous goods transportation industry to achieve overall upgrades and controllable risks.
“High risk, high cost and high profit”, these three high characteristics are the industry characteristics summed up by a dangerous goods transportation practitioner.He said that the transportation of dangerous goods will be fine. If something happens, it will alarm the State Council.Post-event tracing, serious accountability, and industry rectification are all immediate measures.Few dangerous goods transportation companies can bear the risk of such accidents, but they often change their face afterwards, and then they can “reinvent the wheel” after recruiting troops.But the real security issue has not been resolved.
Now, the support of IoT technologies such as in-vehicle intelligence and our proposed blockchain technology solutions are already on the eve of industrial application, and should become the new technology foundation that the dangerous goods transportation industry attaches importance to and adopts.
A large number of facts also prove that in any industry, only those companies that can take the lead in adopting new technologies, applying new standards, and setting new standards can win the industry’s future development opportunities and bring new industry value.
As far as the special industry of dangerous goods transportation is concerned, we hope that the popularization and application of new technologies will greatly increase the safety factor during its operation, reduce safety risks, and make dangerous goods vehicles on the road no longer become an unpredictable one.”Mobile bomb” is no longer a nightmare on the road.
