Introduction: Transportation has always been an important source of economic development, and it is related to the rise and fall of the nation. According to the requirements of economic development, China's high-speed rail technology has undergone earth-shaking changes in the short 16 years. While the domestic high-speed rail is developing and improving, China's high-speed rail technology has even gone global, leading the development of the world's high-speed rail. However, while China’s high-speed rail is bringing convenience and boosting economic development, it also implies a huge potential for public safety.
Advanced technology leads the era of high-speed rail, passenger flow far exceeds expectations
China's high-speed rail can develop rapidly in more than ten years, first of all from technology introduction. Since 2004, the introduction of advanced high-speed rail technology in China and the introduction of advanced technological achievements have enabled China’s high-speed rail companies to have a global technological foundation and gather hundreds of leaders. Second, independent research and development and innovation, China's high-speed rail is not a simple technical reference, but independent digestion and introduction of technology, research breakthroughs and innovation. This is an important reason for the emergence of high-speed rail in China. Third, with institutional advantages, China’s high-speed rail is coordinated by the Ministry of Railways, making China’s high-speed rail into a fist. Such an institutional approach enabled China's high-speed rail development to grasp the technology, and also grasped the market, developed steadily without confusion, and concentrated quickly.
The practicality, soundness, and innovation of technology have made China’s high-speed rails a high-speed, safe, and comfortable feature. Taking the Beijing-Shanghai high-speed rail as an example, the operating speed exceeds 350 kilometers per hour. In 2014, Beijing-Shanghai high-speed rail transported more than 100 million passengers. The increase in passenger traffic has far exceeded expectations. The data proves everything, and the high-speed rail era has arrived!
Public safety pressure, a generation of security system needs to be eliminated
In the entire operation process of the high-speed rail, people are the subjects that can not be ignored, and they are also the source of hidden dangers of public safety. Huge passenger flow will bring enormous public security pressure. At present, China's traffic safety inspection system, including high-speed rail security inspections, mostly uses the first-generation security inspection system. This system is not sufficient to meet the public safety maintenance needs of China's huge traffic flow. Defects in the first generation of security systems :
First, only metal material contraband can be detected. There is no alarm for all types of explosives and firecrackers. The first-generation security system can only recognize the shapes of non-metallic prohibited items by human eyes, and its recognition reliability is unsatisfactory. The false alarm rate of products is generally between 30% and 50%, and sometimes even as high as 60%.
Second, the degree of dependence on manpower is too high. The first-generation inspection system requires human monitoring. The use of uncertainties such as work attitude and responsibility of security personnel ensures safety, making the security unstable and unreliable.
The smooth passage of contraband all the way, the status quo of high-speed rail security is worrying
A few days ago, the Ministry organized and conducted a simulation test on the detection of contraband in the security inspection system : a passenger carried a high-speed rail security screening for all types of dangerous goods (such as fruit knives, firecrackers, and acid chemicals) and tracked it all along the Beijing-Shanghai high-speed rail line. As passengers carried prohibited goods along the way, the security inspection system was just like decoration and it was worrying.
The high precision of high-speed rail car body design and the features of high-speed operation mean that as long as there is a mistake, the consequences are unimaginable. However, there is no excellent security system on the market. This has become a source of tremendous pressure on security systems. In order to ensure the efficient and safe operation of the high-speed rail system and strictly block contraband, it is imperative to upgrade the security inspection system.
The accuracy of the third-generation security system is as high as 90%
It was recently learned that the third-generation security inspection system has been launched into the Chinese security market. The third-generation security inspection system was successfully developed by Zhongfu Optoelectronics Group. The alarm accuracy rate of this system is as high as 90%. It is reported that this system has been tested and widely tested by an authoritative organization. The advantages are:
First, multi-functional composite testing: The third-generation security inspection system breaks through the technical difficulties, can detect metal, solid and liquid in the bag at the same time, covering metal items (such as control tools, guns, charging treasures, circuit boards, etc.), flammable and explosive Products (such as explosives, detonators, firecrackers, etc.), liquid contraband (such as flammable and explosive liquids, acids, alkalis and corrosives, radioactive liquids, etc.)...
Second, intelligent automatic alarm: Compared with the first-generation, second-generation security system, the third-generation security system can automatically alarm immediately, greatly reducing the manpower requirements, but also reduces the probability of false negatives reported, reducing the dependence on manpower.
Third, safe and reliable: The third generation of security system leakage radiation dose rate is very low, in line with all international and domestic radiation safety standards, greatly reducing the radiation damage to the human body.
Fourth, the operation is simple: the third-generation security inspection system software interface is concise and clear, the image processing function is rich, the man-machine interaction is friendly, the software function is powerful, greatly improves the security inspection work efficiency, reduces the public security pressure under the huge passenger flow.

Alluvial Gold Dressing Equipment
The STL water-jacketed Gold Concentrator is a kind of gravity separation equipment. It was developed by Changchun Gold Research Institute Co., Ltd. in 1985 and entered the market. At present, it has been used in many domestic and foreign companies. It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.
The main indicators of this series of equipment basically reach the level of similar international products (such as Nielsen gold selectors, etc.). Compared with similar equipment at home and abroad, this series of equipment has the advantages of high cost performance, easy operation, and low maintenance costs.
