Market research and technical research on RFID card access controller and electric drop bolt lock

1. market background
In 1996, the state began to promote electronic door locks in star-rated hotels (hotel decoration renderings). Hotels that did not use electronic door locks would not be allowed to participate in the acceptance and star rating. Therefore, most of us may be in hotels when we first came into contact with electronic door locks. Judging from the current Chinese market, the vast majority of the customer base of electronic door locks is still focused on organizing users, from the initial hotel to the current real estate, villas (villa decoration renderings), institutions, enterprises, etc., ordinary The share of home users is still very low. According to statistics, electronic door locks in Japan and South Korea occupy more than 70% of the market for civilian locks, and the utilization rate of electronic door locks for apartments in South Korea is as high as 90%. European and American electronic door locks also account for 50% of the market for civilian locks. Electronic door locks in China But it only accounts for less than 2% of the market for civilian locks. The next few years will be a period of rapid increase in the market share of China's electronic door locks; hotels ranging from star-rated hotels to small hotels will realize intelligent management. The national annual real estate investment exceeds 2 trillion yuan, the national real estate decoration market is hundreds of billions, and the national door lock market is tens of billions; in 70 key cities across the country, the average first-hand real estate price exceeds 6,000 yuan / square meter, all of which are intelligent The procurement capacity of electronic locks has gradually formed a real market demand; the national real estate investment reached 4 trillion yuan in 2014, and the demand for mechanical locks and electronic door locks generated by it exceeded 26 billion yuan; Door locks are more than tens of billions; the share of high-end villas and apartments in each city exceeds 6%, and the share of high-end office buildings exceeds 5%. This is an existing market demand.
From this point of view, my country's electronic door lock market still has a lot of room for development. With the promulgation of the national "Twelfth Five-Year Plan", the strategic emerging industries represented by the Internet of Things will become one of the seven strategic industries that my country strongly supports and develops. The country will invest 4 trillion yuan in the next ten years to vigorously develop the Internet of Things, and smart buildings, smart homes, and electronic door locks will be key areas for future development. As an indispensable part of the Internet of Things industry, the "Twelfth Five-Year Plan" provides an opportunity for the development of electronic door locks. In fact, according to research on the physical access control market, more than 70% of end users and 80% of industry respondents believe that in the next 3 to 5 years, they hope to use mobile phones, key tags, tags or credential cards And other ways to replace the current traditional door locks. This is a good thing for the development of electronic door locks. Electronic door locks get rid of the shackles of traditional mechanical keys. Fingers, cards, passwords, remote controls, etc. can all be used to switch the door locks.
It is reported that my country's lock market will continue to grow at an annual rate of more than 20% in the future.

Electronic door lock product classification
Electronic door locks are divided into three categories: smart door locks, electric control locks, and electromechanical integrated locks.
Smart door lock
1. Card-reading smart door locks: smart door locks that are authorized to open using access control cards (such as magnetic stripe cards, IC cards, and proximity cards). There are two working modes, offline or networking, and can be powered by battery or weak current.
2. Password type smart door lock: Enter the smart door lock authorized by password (such as password keyboard type, touch screen type). There are two working modes, offline or networking, and can be powered by battery or weak current.
3. Biometric smart door lock: a smart door lock that is authorized to open through human biological characteristics (such as fingerprints, palm prints, retina, finger veins, facial features, etc.). There are two working modes, offline or networking, and it can work with battery power or weak current provided by the access control system as a power source.
Electric lock
1. Magnetic lock: It is composed of two parts: an electromagnetic main lock body and an armature. Electromagnetic force is generated by electrification to attract the armature to achieve locking. The locking direction is front and rear pull-in, and power off to unlock. There are products with different suction force for selection.
2. Electric mortise lock: consists of two parts: the lock body and the lock plate. Electricity generates electromagnetic force to drive mechanical components to drive the bolt up and down to achieve the locked state. The lock state switch has mechanical top ball type and electromagnetic type. Power off to unlock or lock.
3. Electric lock: the internal electromagnetic solenoid is energized to generate electromagnetic force to drive its mechanical limit device to prevent or release the opening of the electric lock movable plate to realize the locked and unlocked state. Must be used with mortise locks, ball locks and escape devices. Power off to unlock or lock.
4. Shear lock: It is composed of an electromagnetic main lock body and an elastic adsorption plate. The electromagnetic force is generated in the energized state, and the elastic adsorption iron plate is attracted to achieve locking. The locking direction is up and down. In power-off state, there are options for power-off unlock or power-off lock. There are products with different suction force for selection.
Electromechanical lock
Electromechanical integrated lock: The various electronic control functions realized by the close cooperation of the built-in electronic control components and mechanical parts in the mechanical lock body clearly convey the connotation of its electric control lock. The appearance of the mechanical lock, the essence of the electric control lock, the mechatronics lock is named after it.
The most significant functional advantage of the mechatronic lock is its internal and external locking separation function, that is, the door is controlled outside and the door is always open, which effectively solves the contradiction between security and escape.

3. Access control system
Also known as the access management control system, it is a digital management system for the access of managers. Common access control systems include: password access control systems, non-contact card, inductive card access control systems, fingerprint iris palm biometric access control systems, etc. The executive mechanism of the access control system is generally an electromechanical integrated lock or an electric control lock.

4. Production process
1. Surface treatment process of decorative parts:
l Baking paint process: spray several layers of paint on the ground to a certain degree of roughness (usually high-density boards). And it is shaped by high temperature baking. This process currently requires high paint and good color rendering. Its advantages are bright color, strong visual impact, good surface finish, easy to scrub, and good moisture-proof and fire-proof performance. It belongs to relatively high-end surface technology.
2 Spraying process: Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the opposite direction of the electric field and adsorb the paint particles on the surface of the workpiece. The electrostatic spraying equipment is composed of spray gun, spray cup and electrostatic spraying high voltage power supply. Using this process is wear-resistant and durable, and the price will be more appropriate. However, the possible uneven textures on the surface have a certain impact on the visual effect, and the surface technology of spraying has limited resistance to the environment.
3 Electroplating process: The electroplating process is the most familiar surface process. Through electrolysis, the cations of the metal to be plated in the plating solution are deposited on the surface of the base metal to form a surface processing method of the plating layer. The operation is simple, the cost is cheap, and the common electroplated chrome can bring good hardness and good color. But it is not as good as other processes in corrosion resistance.
2. Decoration materials and processing technology:
l Zinc alloy die-casting: good formability, high strength, suitable for electroplating.
2 Aluminum alloy casting: light weight, but poor strength, not suitable for electroplating
3 The proportion of zinc alloy is about 2.5 times that of aluminum alloy, and the price is equivalent, so the material cost of zinc alloy is two or three times more expensive than aluminum alloy. Many companies now want to use aluminum alloys to replace zinc alloys in order to save costs, but some cannot be replaced because the strength, hardness and formability of zinc alloys are much better than aluminum alloys. If the surface of your product needs to be polished and electroplated, and high appearance quality is required, then zinc alloy must be used. Aluminum alloy material is difficult to meet high surface quality requirements, because aluminum alloy die-casting performance is poor, and there are many pores on the surface of the product, and the surface quality after electroplating is very poor.
3. Lock body material and processing technology:
Available in stainless steel, copper, iron, zinc alloy
l The best material should be stainless steel, especially for surface materials, the more you use it, the brighter it will be. It has good strength, strong corrosion resistance and unchanged color. However, there are many types of stainless steel, mainly divided into ferrite and austenite. Ferritic stainless steel 201 is magnetic, commonly known as stainless steel. It will rust for a long time and in a bad environment. Only austenitic stainless steel 304 will not rust. The general processing technology is precision casting or powder metallurgy. Precision casting has good strength and good electroplating performance, but the size consistency is poor and the price is high. The powder metallurgy has poor strength and poor electroplating, but the size is the same and the price is low.
2 Aluminum or aluminum alloy, ordinary aluminum alloy (except for aerospace use) is soft and light, and the material strength is lower. The processing technology is casting or profile. Easy to process and shape. But the carrying capacity is relatively low.
3 Copper material: good corrosion resistance, excellent electroplating performance, but high price, lower strength than stainless steel material, processing technology is casting or profile.
4 Iron material: good strength, low cost, but easy to rust. Electroplating is required to meet the anti-corrosion requirements, and the processing technology is profile or mechanical processing.
Compared with stainless steel, zinc alloy materials have much worse strength and rust resistance, but higher than aluminum alloys. The processing technology is die-casting processing.
