1. The market background
In 1996, the country began to promote electronic door locks in star hotels (hotel decoration effect diagram), the hotel without electronic door locks will not be able to participate in acceptance, can not be rated star. As a result, most of our first encounters with electronic door locks were probably in hotels. From the current Chinese market, the vast majority of the electronic door lock customer base is still only concentrated in the organization of users, from the beginning of the hotel to the present real estate, villa (villa decoration effect diagram), institutions, enterprises, and so on, the average family user share is very low. According to statistic, electronic door lock of Japan and Korea occupies the market of civil lock above 70%, the utilization rate of electronic door lock of Korea apartment is even as high as 90%, euramerican electronic door lock also occupies the market of civil lock 50%, Chinese electronic door lock occupies the market of civil lock less than 2% only however. The next few years will be a rapid period of China's electronic door lock market share; Big to star class hotel small to inn inn will realize intelligence to manage. Every year, the real estate investment in China exceeds 2 trillion yuan, the national real estate decoration market is hundreds of billions yuan, and the national lock market is over 10 billion yuan. In 70 key cities across the country, the average price of real estate in a primary building exceeds 6,000 yuan/m2, all of which have reached the purchasing ability of smart electronic locks and have gradually formed a real market demand. In 2014, the national investment in real estate reached 4 trillion yuan, and the demand for mechanical locks and electronic locks exceeded 26 billion yuan. National redecoration and second-hand real estate decoration demand of the door lock more tens of billions of yuan; Each city's high-end villas, apartments share more than 6%, high-end office buildings share more than 5%, this is the reality of the existing market demand.
So, the electronic door lock market of our country still has very big development space. With the introduction of the 12th Five-Year Plan, the strategic emerging industry represented by the Internet of Things will become one of the seven strategic industries to be vigorously supported and developed in China. The country will invest 4 trillion yuan in the next decade to vigorously develop the Internet of things. Smart buildings, smart homes and electronic door locks will be the key areas for future development. As an indispensable part of the Internet of Things industry, the 12th 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 percent of end users and 80 percent of industry respondents believe that in the next three to five years, they want to replace traditional door locks with cell phones, key plates, tags or credential CARDS. This is good news for the development of electronic door locks. Electronic door lock got rid of the bondage of traditional mechanical key, finger, card, password, remote control can be used to switch the door lock.
It is reported, market of lock of our country in the future still will grow with the rate of above 20% every year.
2. Product categories
Classification of electronic door lock products
Electronic door lock is divided into three categories: intelligent door lock, electronic control lock and electromechanical integrated lock.
Smart door lock
1. Card reader smart door lock: Smart door lock opened by authorization of access control card (such as magnetic stripe card, IC card and induction card). There are offline or network mode of operation, battery or weak current power supply.
2. Password type smart door lock: enter password authorization to open the smart door lock (such as password keyboard type, touch screen type). There are offline or network mode of operation, battery or weak current power supply.
3. Biometric smart door lock: intelligent door lock authorized to be opened by human biological characteristics (such as fingerprint, palmprint, retina, finger pulse, facial features, etc.). There are two kinds of working modes: off-line or networked, which can be operated by battery power supply or weak current provided by access control system.
Electric control lock
1. Magnetic lock: It is composed of electromagnetic main lock body and armature. Electromagnetically absorbing armature is generated by electric current, so as to achieve locking. There are different sizes of suction force products to choose from.
2. Electric plug lock: it is composed of the lock body and the lock gusset plate. Electrifying produces electromagnetic force to drive the mechanical component to drive the latch to move up and down to achieve the locking state. The locked state switch has mechanical dome 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 the mechanical limit device, prevent or release the opening of the movable plate of the electric lock, and realize the state of locking and unlocking. Must be used in conjunction with cartridge lock, ball lock and escape device. Power off to unlock or lock.
4. Shear lock: it is composed of electromagnetic main lock body and elastic adsorption plate. Electromagnetic force is generated in electrified state. Power off state, can have power off unlock or power off lock to choose. There are different sizes of suction force products to choose from.
Electromechanical integrated lock
Electromechanical integrated lock: through the mechanical lock body built in the electronic control components and mechanical components closely cooperate to achieve a variety of electronic control functions, and clearly convey the connotation of its electronic control lock. The appearance of the mechanical lock, the nature of the electronic control lock, the electromechanical integration lock is named.
The most significant functional advantage of electromechanical integration lock is its internal and external lock separation function, that is, the door is controlled outside, the door is often open, effectively solve the contradiction between security and escape.
3. Access control system
Also known as access management control system, is a management personnel in and out of the digital management system. Common access control systems include: password access control system, non-contact card, inductive card access control system, fingerprint iris palm biometric access control system, etc., the executive mechanism of access control system is generally electromechanical integrated lock or electronic control lock.
4. Production technology
1. Surface treatment technology of decorative parts:
Paint baking process: spray several layers of paint on a base (usually a high-density plate) that has been ground to a certain degree of roughness. And by high temperature baking finalize the design. This process has a high requirement for paint and good color rendering. Its advantage is colour and lustre is bright-coloured, have very strong vision wallop, surface is smooth degree is good, easy scrub, have good moistureproof, fireproof performance belongs to more high-end surface craft.
2 spraying process: Electrostatic spraying is a spraying method that USES high voltage electrostatic field to make the negatively charged paint particles move in the opposite direction of the electric field and adsorb the paint particles on the surface of the workpiece. Electrostatic spraying equipment is composed of spray gun, spray cup and electrostatic spraying high voltage power supply. Adopt such craft wear-resisting and durable, the price also can be more appropriate. However, the non-smooth lines that may exist on the surface have a certain impact on the visual effect, and such a surface technology as spraying has limited resistance to the environment.
Electroplating process: Electroplating process is one of the most familiar surface processes, through electrolysis, the plating solution to gold plated cationic deposition on the surface of the matrix metal, forming a coating surface processing method. Easy to operate, cheap to build, the common chromium electroplating can bring good hardness and good color. But the corrosion resistance is not as good as other processes.
2. Decoration materials and processing technology:
L Zinc alloy die casting: good forming performance, high strength, suitable for electroplating.
2 aluminum alloy casting: light weight, but poor strength, not suitable for electroplating
The specific gravity of 3 zinc alloy is aluminium alloy 2.5 times or so, and the price is equal, so cost of material zinc alloy is more expensive than aluminium alloy two or three times. Now many enterprises in order to save costs, want to use aluminum alloy instead of zinc alloy, but some can not be replaced, because the strength of zinc alloy, hardness and molding performance are much better than aluminum alloy. If you want to polish and electroplate the surface of your product, and require very high appearance quality, that must use zinc alloy. Aluminum alloy material is very difficult to achieve very high surface quality requirements, because aluminum alloy die casting molding performance is poor, in the product surface is easy to product a lot of pores, electroplating out of the surface quality is very poor.
3. Locking material and processing technology:
Stainless steel, copper material, iron material, zinc alloy material choice
L The best material should be stainless steel, especially as a surface material, the brighter you use it. It has good strength, strong corrosion resistance and constant color. But there are a variety of stainless steel, mainly divided into ferrite and austenite. Ferrite stainless steel 201 is magnetic, commonly known as rust iron, for a long time, the environment is not good will rust, only austenite, stainless steel 304 will not rust. General processing technology is precision casting or powder metallurgy, precision casting strength, good electroplating performance, but poor dimensional consistency, high price. Powder metallurgy, poor strength, poor electroplating, but the size of the same model, low price.
Aluminium or aluminium alloys, ordinary aluminium alloys (except for aerospace applications) are soft and light in quality and have low material strength. Processing technology for casting or profile. Easy to process and form. But the carrying capacity is low.
Copper material: good corrosion resistance, excellent electroplating performance, but high price, lower strength than stainless steel material, processing technology for casting or profile.
4 Iron material: good strength, low cost, but easy to rust. Electroplating is needed to meet the anti-corrosion requirements. The processing technology is profile or mechanical processing.
Zinc alloy material, relative to stainless steel, its strength and rust resistance is much worse, but higher than aluminum alloy. The processing technology is die casting.
