Today, we share with you about the technology and development of vehicle safety inspection in logistics park. At first glance, you may think that this has little to do with the Smart Logistics Park. In fact, this is the same technology as the positive driving force for the development of the logistics industry, which is conducive to the development of logistics parks. In reality, there are also some constraints affecting the development of the logistics industry, such as the upgrading of anti-terrorism and stability; or with the increase of railway, civil aviation, port, postal security and investment, the concealment of the huge road transport network and freight vehicles will increasingly become the transportation channels of prohibited goods; or It is the transportation factor of dangerous chemicals. There are more than 300,000 dangerous chemicals enterprises and more than 5,000 chemical raw materials are commonly used. More than 95% of chemical raw materials need to be transported in different places. The total amount of dangerous chemicals transported by road every year has exceeded 300 million tons. There are more than 10,000 road dangerous goods transportation enterprises in our country, and more than 300,000 transport vehicles. Flammable and explosive materials threaten the safety of logistics parks. In addition, as far as the logistics park is concerned, there are still many factors restricting its development. For example, the logistics industry only relies on small charter planes to check small cargo and express delivery, large cargo vehicles with greater hidden dangers and no technical equipment to check, such as individual charter planes for each cargo in the vehicle. It will greatly affect the efficiency of logistics park. In view of this situation, the government departments have issued corresponding policies. The Annual Notice of the Ministry of Transport on Strengthening Safety Management in the Acceptance Link of Road Freight Transport issued in 2011 requires that large-scale security checkers should be installed at large stations where conditions permit, so as to prevent dangerous goods from entering or boarding. In 2015, 10 ministries and commissions jointly issued "Some Opinions on Strengthening Logistics Safety Management", pointing out that we should promote the use of technical means to detect and inspect containers and cargo goods, and improve the ability to detect contraband and dangerous goods. Article 20 of the Anti-terrorism Law of the People's Republic of China promulgated in 2016 requires freight transport and postal and express delivery units of railways, highways, waterways and airlines to implement a safety inspection system, check the identity of customers, and carry out safety inspection or Kaifeng of goods transported or delivered in accordance with regulations. Examination. No goods prohibited from transporting or delivering may be transported or delivered if there are major potential safety hazards or if the customer refuses to carry out safety inspection. In summary, we can see that not only the transport vehicles loaded with dangerous chemicals and contraband enter the logistics park, which seriously endangers the logistics park and social security, but also the state issued three policies in 2012, 2015 and 2016, which put forward requirements for the security inspection of the logistics park. Therefore, logistics parks need to equip a modern large-scale vehicle inspection equipment, which is of great significance in combating criminal activities, maintaining social stability and the safety of logistics parks themselves. Hualixing is an enterprise that provides professional services in this field. At the technical level, Hua Lixing's perspective imaging technology uses cobalt-60, accelerator and other radiation sources to emit penetrating rays, penetrate the closed vehicle, and receive radiation signals by the detector on the other side of the vehicle, thus forming an internal cargo scanning image. This technology has been widely used in many fields in China. It was used in customs container smuggling inspection in 1999, in rolling dock vehicle security inspection in 2002, in Olympic vehicle security inspection in 2008, and in highway fresh agricultural products inspection in 2010. Hualixing's security inspection technology and equipment are all pioneering applications in these three areas. In view of the demand of vehicle security inspection in logistics park, Hualisheng has put forward the solution and layout scheme of large-scale vehicle inspection in logistics park. The security inspection is carried out through PDS1000 and PDS6000 fast-passing vehicle security inspection equipment. These equipments have the characteristics of high throughput, automatic operation, small occupancy, all-weather work, safety chain, high reliability, head avoidance, high safety, small occupancy, energy saving, environmental protection, radiation safety and so on.
