Internet of Things Technology: Leading a New Age of Lock Security

In recent years, the technological advances in the field of lock and security have been astounding, and the alarm-free refrigerator is just one of them. It applies only a relatively simple integration technology, but this shows a new direction of development in the lock security industry: the application of Internet of Things technology.

In the future, this alarm device will be able to be integrated in many products. After an abnormal situation is detected, it is not only limited to sounding an alarm, but it is transmitted through the wireless communication network, real-time conditions such as security, lighting, air conditioning, heating, and even remote transmission of the screen. To the owner's mobile phone, or when someone enters illegally, the police's alarm system is directly connected to provide the address, coordinates, and images. This is the true Internet of Things security products.

Recently, with my curiosity about this new technology, the author visited the organizer of 2011 China International Locks and Security Products Exhibition (CILS) who has been committed to promoting the new technology of lock security, and Ms. Shi Xiaolan, Executive Vice President of China Hardware Products Association. Answered questions about the Internet of Things for us.

According to Shi Shi’s briefing, “The Internet of Things” is defined as: through information-sensing devices such as radio frequency identification (RFID), infrared sensors, global positioning systems, and laser scanners, according to the agreed agreement, The Internet connects and exchanges information and communications to realize a network that intelligently identifies, locates, tracks, monitors, and manages.

The concept of "Internet of Things" was put forward in 1999. "Internet of Things" is the "Internet of Things Connected." This has two meanings: First, the core and foundation of the “Internet of Things” is the Internet, which is an extension and expansion network based on the Internet; secondly, its user end extends and expands between any items and objects. Information exchange and communications.

"In China, the application of the "Internet of Things" technology in the field of security products has always been at the forefront. Based on the basic principle of the "Internet of things," the security system in residential homes can now be remotely controlled and monitored. This is the "Internet of Things." "The first step taken by the technology." Shi Shek-chang said.

“But at present, this kind of technology still stays in the labs of high-tech companies, research institutes, and some top-level lock security exhibitions. Due to cost and other reasons, it will take some time for smart security systems to be applied in large areas. But it is certain that The "Internet of Things" technology will certainly be a major trend in the development of the lock and security industry. "The chairman of the stone management said," China's lock and security companies are not involved in this area, and some companies even for the "Internet of things" The concept is not very clear, and it is very dangerous. This part of the company is very likely to face the risk of being eliminated in the future "Internet of Things" technology's rapid development."

"Of course, there are still some companies that have begun to get involved in this area and have achieved certain results. The 2011 China International Lock and Security Products Fair will be held on September 21 this year at the new International Exhibition Center in Shanghai. The organizer will invite leading companies in relevant technology fields to participate in the exhibition and share the charm of this new technology application with the vast number of locks and security companies. "Shizi Director will continue the introduction. "At present, we are planning to hold the "Internet of Things" during the exhibition. The era locks and security product trends forum or seminar, invited the "Internet of things" research and locks, security industry experts and conferences, popularize the "Internet of things" knowledge, interpretation of the national "IoT" construction plan for the development of the industry, common Promote the majority of locks and security companies to grasp the future development of the industry."

According to briefing by Shi Shi, the China International Lock and Security Products Fair is the world's second largest hardware exhibition - China International Hardware Show (CIHS) special exhibition, by the China National Hardware Association, Germany Cologne International Exhibition Co., Ltd., the National Federation of Industry and Commerce Hardware The electromechanical chamber of commerce and the China Light Industry Branch of the China Council for the Promotion of International Trade jointly sponsored by Beijing Shirui Exhibition Co., Ltd. and Shanghai Continental Tools Development Co., Ltd., supported by the Federation of International Hardware and Household Products Associations, was positioned as "internationalization, domestic demand market development, and technology orientation. Brand Promotion".

The 2010 China International Lock and Security Products Fair attracted more than 40,000 professional visitors and nearly 3,000 overseas buyers, of which more than 36.2% came from Europe and the United States, and the rest came from the Middle East, Africa, and Southeast Asia. Among the professional visitors, 30.54% are traders and importers and exporters, 31.23% are manufacturing end users, and 20.01% are hardware lock dealers and distributors. 72.9% of the audience come from corporate management and decision-making.

“The 2011 China International Lock and Security Products Exhibition will expand its area by 20% on the basis of 2010. It is expected that there will be more than 400 exhibitors, professional visitors are expected to reach 45,000, and overseas buyers are expected to exceed 3,000. "The chairman of the stone said finally.

NSK Bearing

NSK manufacture a full range of deep groove ball bearings. These bearings are the most common type and are used in a wide variety of applications.

Single-Row Deep Groove Ball Bearings
Pressed Steel Cages
Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread.
In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.
For big deep groove ball bearings, machined brass cages are used.
Machined cages are also used for high speed applications.

Extra Small Ball Bearings and Miniature Ball Bearings
Miniature and instrument ball bearings can be divided into two basic types, deep groove and angular contact. The first (deep groove) can be further divided into the following five classes depending on their design details:

Standard type
Flanged outer ring
Extended inner ring
Expanded type in which one ring has a radial thickness that is larger than normal compared with the bearing width.
Thin section type in which both rings are extra thin in the radial direction. They can also be classified as: open, shielded, or sealed.
Maximum-Type Ball Bearings
Maximum-Type ball Bearings contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings. Because of their filling slots, they are not suitable for applications with high axial loads. types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 6200 and 6300 respectively. Besides the open type, ZZ type shielded bearings are also available. When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible. Their cages are pressed steel.
