Currently, the application of face recognition technology in the fields of finance, security, access control, public security, transportation, education and mobile payment is gradually increasing. Among them, finance and security are two areas where the face recognition technology is relatively easy to realize commercialization. Therefore, Its application is relatively mature. This article excerpted Industry Research Institute report "face recognition industry research report", a good demonstration of the B-face recognition industry market. Face recognition technology rapid development in recent years, recognition accuracy and speed of effective promotion of face recognition in many fields provides a basis for face recognition applications since 2015 began to gradually increase, from the previous access control attendance Mainly to the public security, transportation, finance, education, real estate, mobile payment and other fields to expand. In particular, from the second half of 2016, application cases of various types have landed far faster. As of now, cases of public face anti-terrorism combined with face recognition have already taken place in Beijing, Shenzhen and Guangzhou. Traffic has dropped in the C-market Has begun to use the brush face, 2017 Spring Festival return multiple high-speed rail stations have applications. Dozens of banks in the financial field, including the top four banks, have all introduced face recognition products in various business sectors from the second half of 2016 to the end of 2016. The fields of education include the entrance examination in 2016, Beijing, Sichuan, Hubei, Guangdong, Liaoning, Inner Mongolia and so on Provinces used a "face recognition + fingerprint identification" biometric identification of candidates to confirm the identity. With the development of pilot areas and cases in various fields and the maturity of operational models, the Institute for Industry Research estimates that face recognition in 2017 is expected to usher in large-scale popularization. B-side incremental market core power lies in building a large security system. B market covers many areas, the traditional market mainly in attendance attendance, from public security, transportation, education and medical industries and other industries are incremental markets, are on the face recognition products have certain needs. Face recognition products can effectively identify whether the identity is fraudulent or not. Through the networking with the back-end system, it is of great significance to quickly retrieve the target person and to ensure the security and stability of the society. Therefore, the core of its needs in the field of industry lies in security, and the government driving force for the popularization of products is also in the fields of security and multi-industries, which will help build a large security system. We think the current face recognition product industry is at a good time. The state has already started to introduce relevant policies in 2015 to speed up the construction of a security system. It is explicitly required that the network monitoring rate of video surveillance in key public areas will reach 100% by 2020; the networking rate of video image resources in key industries and public areas will reach 100%. After nearly two years of construction, the traditional video surveillance system in the city has been well established and the video surveillance resources have been improved. The next issue is how to effectively use data resources and deepen the construction of video surveillance system. Face recognition provides better ideas in three aspects: The backstage support system uses the dynamic face recognition system to retrieve the stock videos and enhances the use efficiency of resources, abandoning the original manual retrieval. Security will be raised to the matter and even before the stage. Video surveillance system and the public security data system interconnection can help identify suspects in advance, even before the event to stop in a timely manner. In-depth mining of each subdivision scene, such as face recognition products in the police handheld terminals, the hotel front desk, examinations, hospitals and medical use of the scene, to further refine the application scenarios, further monitoring system construction. We sort out several major industry application scenarios of face recognition and estimate the market size: Public security: The use of face recognition products in the public security area is mainly reflected in two aspects. One is the use of a background dynamic face recognition system, and the other is the use of a front-end face recognition handheld device and a person-ID comparison machine. The dynamic face recognition system is based on the calculation of only the prefecture-level administrative regions. Each prefecture-level administrative region has set up a face recognition system. Assuming that it needs 2 million, the number of the prefecture-level regional divisions is 334, and the overall market size is up to 667 million. Hand-held face comparison device in accordance with a single device 1000 yuan calculation, the country about 2 million police force, assuming the inspection police accounted for 10% of the total, the market size 200 million yuan. Accreditation comparison machine at the border check, the police station staff identity checks are required, only the calculation of the police station requirements, the national township level division number 39789, conservatively estimated that each township configuration 1 police station, a single device 20,000 yuan, the market size of 790 million yuan. Therefore, without considering other criminal investigation and anti-terrorism scenarios, the market size of the public security system can exceed 1.6 billion yuan. Traffic: The main application scene in the field of traffic lies in the deployment of face recognition devices at the security gate and the gate of the ticket gate. Including airports, railway stations, bus stations, docks and other locations. Spring Festival in 2017, there are some high-speed rail station face brushing face security pilot. We estimate the market size of the transportation sector as a whole. According to the calculation of a single gate access equipment of 100,000 yuan, there are 516 high speed rail stations, 210 civil aviation airports, over 2,000 general passenger train stations and more than 2,000 long-distance passenger transport stations. In the early stage of high-speed rail stations and airports, the scene landed fast. Based on the average demand of substituting 10 gateways for each site, the market size was about 720 million yuan. Considering the follow-up scenarios such as the replacement of ordinary train stations and long-distance bus terminals, the entire market scale Expected to exceed 5 billion yuan. Finance: In the field of finance, face recognition products are mainly used for banking face matching, face-opening accounts and face-brushing withdrawals. Therefore, the requirements of witness-to-device comparison are stronger. At present, there are already many banks including ABC, China Construction Bank and Minsheng Bank that introduce face recognition into different business processes. According to the statistics of the People's Bank of China, in 2015, the number of outlets of financial institutions reached 220,700, of which 69,293 were large-scale commercial banks. Therefore, based on a single equipment of 20,000 yuan and two outlets of each branch, the size of the large commercial bank You can reach 2.8 billion, the overall market size is in billions of level. Education: The main needs of the education industry is the identification of candidates identity, campus, dormitory access management and other scenarios. As the state severely punished candidates for exams and cheating on important exams, the college entrance examination in 2016 adopted the biometrics technology of "face recognition + fingerprint identification" in Beijing, Sichuan, Hubei, Guangdong, Liaoning, Inner Mongolia and other provinces to confirm candidates' identity , To prevent the test, cheating incident. With the concern of society on campus security, some colleges and universities have also started using face recognition for campus and dormitory access management. According to the statistics of the Ministry of Education, there were 2,845 colleges and universities, 249,000 compulsory education schools and 223,700 kindergartens in 2015. Therefore, the entire market scale of education will reach 10 billion level. Through the statistical analysis of the above major areas, it can be seen that there are abundant application scenarios for face recognition and the market size is huge. Without regard to the 100 billion security market that can be extended in the future, only the market scale in public security, transportation, finance and education can reach hundreds Billion size. Under the core driving force of security, the B-side market landing cases continue to emerge, is expected to be the first to erupt.
Natural Graphite, as its name implies, is naturally formed by natural graphite, which is generally found in graphite schist, graphite-gneiss, graphite-bearing schist and metamorphic shale.
Features
The chemical composition of graphite is carbon (C). Naturally produced graphite is rarely pure and often contains impurities, including SiO2, Al2O3, MgO, CaO, P2O5, CuO, V2O5, H2O, S, FeO and H, N, CO2, CH4, NH3, etc. Natural graphite minerals are black, steel gray, striated black; Metallic luster, crypto, dull, opaque; The hardness is isotropic, the vertical cleavage surface is 3 ~ 5, the parallel cleavage surface is 1 ~ 2; Qualitative soft, density is 2.09 ~ 2.23 g/cm3, have the feeling of greasy, easy to contaminate finger. Mineral chip under the transmitted light is generally not transparent, extremely thin can pervious to light, the light green gray, refractive index of 1.93 ~ 2.07, under the reflected light is light gray, reflective pleochroism, Ro gray with brown, Re dark blue gray, reflectivity Ro23 (red), Re5.5 (red), the reflected color, double reflection were significantly, strong heterogeneity, polarization color for straw yellow.
Graphite is a complex six-party double cone, assumes the six-party tabular crystal, common simplex are parallel double, six-party double cone, hexagonal prism, but in good condition with rare crystal forms, the generally show scaly or platy, aggregate density lump, earthy or globular.
Type
The process performance and usage of graphite is mainly depends on the degree of crystallization, in accordance with its natural graphite crystal morphology can be divided into crystalline graphite, Flake Graphite) and aphanitic graphite (earthy graphite) two types of industry.
Crystalline graphite
In the crystalline (scale) graphite ore, the diameter of graphite crystals is greater than 1 mu m. Ore grade is low, but optional; The mineral associated with graphite is usually mica, feldspar, quartz, diopathic stone, diabase, garnet and a small amount of pyrite, calcite, etc., some of which have some useful components, such as rutile and vanadium. The ore is scales, grainy scales or granulocyte structures, flaky, flaky, or blocky structures.
Crystalline (scale) graphite is divided into High Purity Graphite, high carbon graphite, medium carbon graphite and low carbon graphite according to the fixed carbon content.
The high purity graphite (fixed carbon content is greater than or equal to 99.9%) is mainly used for flexible graphite sealing material, nuclear graphite, instead of platinum crucible for chemical reagent melting and lubricant base material, etc.
High carbon graphite (fixed carbon content 94.0% ~ 99.9%) is mainly used for refractory materials, lubricant substrate, brush raw materials, carbon products, battery raw materials, pencil materials, filling materials and coatings, etc.
Carbon graphite (80% ~ 94% fixed carbon content) is mainly used for crucible, refractories, casting materials, foundry coatings, pencil raw materials, battery materials and dyes, etc.
Low carbon graphite (fixed carbon content 50.0% ~ 80.0%) is mainly used for foundry coatings.
Cryptocrystalline graphite
Cryptocrystalline graphite is also called soil graphite or amorphous graphite. In cryptocrystalline graphite ore, graphite crystals are less than 1 mu m in diameter, which are microcrystalline and can only be seen in the electron microscope. High grade of ore, but poor selectable; The mineral associated with graphite is often quartz and calcite; The ore is microscaly - cryptocrystalline structure, block or soil structure.
Cryptocrystalline graphite ore is mainly distributed in contact metamorphic deposits. Actually the diameter graphite flake graphite ore is uneven, the so-called crystalline graphite ore, may also contain the aphanitic graphite, are too many content is often referred to as the mixed type graphite ore, may also contain a small amount of aphanitic graphite quality mineral crystalline flake graphite piece diameter slightly larger than 1 microns.
Cryptocrystalline graphite ore is mainly used in pencil, battery, electrode, graphite emulsion, graphite bearing ingredients and the raw materials of battery carbon rod. The non-ferrous graphite is mainly used for casting materials, refractory materials, dyes and electrode paste.
