Recently, NFC applications have been combined with Taiwan ’s Chunghwa Telecom, Yoyo Card Company, NXP and financial companies, and finally combined smart phones with NFC technology for practical applications, and RIM also introduced NFC technology on the new BlackBerry. The NFC application has finally moved from the leisure card to the smartphone field, which also means that the Internet of Things has taken another big step from the mature stage.
The Internet of Things has a wide range of aspects. This time we will start from the perspective of NFC applications. In addition to understanding the status of NFC applications and technological development, we will also look at the MCU, terminal applications, wireless communications, etc. to understand what various players think about the Internet of Things .
The term The Internet of Things, or the M2M (machine-to-machine) technology mentioned abroad, can be said to be basically the same in terms of application concepts. In general, the definition of the Internet of Things is mainly to introduce all entities into the sensing system and wired or wireless networking technology, so that they can communicate and share information with each other, and even further analyze the information into more valuable data, let When people are doing various jobs or work, they can greatly reduce unnecessary costs or time.
The origin of the term Internet of Things comes from the mainland. Due to the large population of the mainland, it has become the world's largest consumer market. If you can connect electronic devices within the mainland, the benefits that can be produced are bound to be quite amazing. According to the plan of the Ministry of Industry and Information Technology of Mainland China in June 2010, during the period of the 12th Five-Year Plan promoted by the mainland, the China Internet of Things Standards Joint Working Group will be established in Beijing to formulate the Internet of Things standards. The mainland industry predicts that by 2015, the Internet of Things industry will reach a scale of 700 billion yuan.
From the definition of the Internet of Things, the range of applications it can cover is quite wide, from smart grid, home automation, public safety, homeland security monitoring, NFC (Near Field CommunicaTIon; near field communication or short-range wireless communication), RFID ( Radio Frequency IdenTIficaTIon (radio frequency identification), logistics management, telecommunications industry, Internet, etc., can all be included in the application range of the Internet of Things. Therefore, in the discussion of the Internet of Things, each application or major player in the technical field will have a slightly different perspective when observing the current status or future development of the Internet of Things.
From the perspective of logistics management, it is necessary to build a complete platform for the Internet of Things
Lin Hankun, the project manager of the NEC Planning Department in Taiwan, said that NEC has a lot of experience in RFID in the past, and it will be extended from RFID in the development of the Internet of Things. For RFID applications, such as access control systems, production processes or logistics management, are all application fields that RFID can import, and the role played by NEC is to provide complete system integration solutions for enterprise-end customers To use it, you must build a platform to integrate the back-end database, such as the solutions provided by Oracle and Cisco, and the front-end must also integrate the reading system. However, Lin Hankun also mentioned that for the logistics management system alone, it is relatively inadequate to control with RFID. It must combine temperature, humidity, impact and pressure sensing components. When the goods are being transported, they can be understood in the first place. And control the on-site condition of the goods. For example, when shipping cantaloupe from the origin, the operator can take the picture first, then send it to the background to build the file, and after delivery to the destination, the picker can take another photo action and then compare the photos. Confirm whether the cantaloupe is damaged. From the beginning of the delivery to the pickup, the Internet of Things is responsible for data transmission.
RFID applications also need to consider security mechanisms
Lin Hankun further mentioned that NEC has also been cultivating for a long time in the field of Internet of Things. In this year's mainland market, NEC has provided related IT technologies to mainland industry players. Networking to cloud computing creates a comprehensive and highly integrated platform, so it also spawned issues related to private cloud and data confidentiality. He also revealed that this year NEC will show a special tablet computer dedicated to enterprises in Japan, which has a built-in RFID two-way communication module. Through the establishment of this function, employees can start up by using the employee ID of the built-in RFID antenna Use an exclusive tablet computer. In addition, due to the establishment of the Internet of Things and confidential data within the enterprise, as long as the enterprise employees log in to the company's internal website remotely and then use the printer's RFID reading system, they can print the internal data.
Return to application orientation from the technical field
However, the technology of the Internet of Things covers a wide range, and the business opportunities are also quite huge, so that many manufacturers have rushed into this market to share the pie. In various applications of the Internet of Things, various technical camps have indeed formed a situation in which they intend to take a leading position in certain applications. Lin Hankun said bluntly, whether it is ZigBee or Bluetooth, it will be the technical field that NEC will focus on in the development of the Internet of Things. Taking ZigBee as an example, the application field in the mainland will be placed on the positioning of equipment, such as expensive diagnostic equipment in medical institutions. Once the equipment is idle, it is a waste of resources from the perspective of management level. . But after all, ZigBee is one of the active RF technologies. The battery is built in the front-end device to operate. Therefore, the durability of the system must be considered, and the replacement problem must also be considered in actual management. This Are all parts to be considered.
