Weihai Beiyang electric group co., Ltd. (hereinafter referred to as the Northern Group) was founded in 1988, is one of the comprehensive State-owned holding enterprises, high-tech enterprise of the group, since 1993 the Chinese electronics industry enterprises for 15 consecutive years. with State-level Enterprise Technical Center and provincial Engineering Research Center. 93.54 million Yuan registered capital, has formed the optical fiber sensors, radio frequency identification (RFID)/image sensor, a private printer, thermal printing head, energy-efficient lighting, electronics parts, and other varieties of six series of nearly.

in recent years, the Northern Group backed by high-tech electronic technology, technology introduction, digestion and absorption on the basis of, successively took on more than 20 national-level and provincial-level new product development projects, 7 of which filled the domestic blank, and achieved international technical and quality level of similar products.

in radio frequency identification (RFID) technology, Northern by virtue of its strong research and development and the accumulation of radio frequency technology for many years, developed a series of high-frequency (HF) equipment to read and write, products subject to ISO18000-3, ISO15693, a number of international standards such as ISO 14443A/B. products with completely independent intellectual property rights and patents, barrier-free access, smart shelves, far from the reader/reader performance in the domestic leading level in the distance. has been widely used in intelligent asset management, personnel management in home-school connection, open and smart libraries, open access, open, Conference attendance, barrier-free access, attendance management, digital valuables ticket management, medical management, product security, logistics and supply chains, and other areas. developed by RF printer (RFID printers) with electronic labels print plain text information in real time on the surface, the read/write function of electronic data in the label, can be easily read and artificial reading of the machine, can be widely used in Logistics Automation, health care, transportation, production line management, library management and animal husbandry, and other areas.

in the field of optical fiber sensing technology, distributed optical fiber temperature sensing technology developed in recent years for real-time monitoring of temperature field of high-tech, can be widely used in fire alarms, process control, gas leak monitoring and fault diagnosis of liquid, and so on. relying on the Northern Group in the domestic leading position and strong technical strength, developed 2KM/4KM/10KM, a variety of distributed optical fiber temperature sensor, sensor optical fiber has a small size, light weight, low cost, simple structure, easy to use, can be continuously distributed measurement of high temperature, high pressure and from electro-magnetic interference, system safety and reliability. the technical performance and unparalleled advantage over traditional electronic sensor products, technology has reached the international advanced level. products have been widely used in port, the coal and power industries as well as tunnels, subways, roads, and water conservancy construction of petrochemical and other industries, are the user's consistent high praise. as a complement to distributed fiber optic temperature sensor of Fiber Bragg grating, not only within a short time-point measurement, and more accurate, be recognized by the industry and customers, meet the actual needs of the user.

in barcode automatically recognition technology area, Northern Group break abroad patent technology blockade, constantly for technology innovation, has development out has independent intellectual property, and reached international advanced level of series hot printer, and high speed bills scanner, and barcode General read instrument, new products, which, "portable hot sensitive printer" and "small hot go printing printer" won "1999 of national new products" ; "Small thermal transfer printing printer "has won" 2000 of Shandong province technology progress first prize ", and" Shandong province excellent new products "and the" 2001 national technology progress second prize ";" high speed bills scanner "won" 2001 of national new products ", and" 2002 of Shandong province technology progress third prize "," barcode General read instrument "and" II dimension barcode General read instrument "won" 2002 national new products ". the Northern Group in the area of bar code automatic identification technology domestic technology and mass production lead.
