There is no cloud mirror in Kyushu, and the most reunion night is the Mid-Autumn Festival. The Mid-Autumn Festival, a traditional Chinese festival, is coming soon. In order to celebrate the Mid-Autumn Festival in advance with our customers who have always supported and trusted our company and the employees who have dedicated themselves to the company, our company held a grand tasting of Italian famous wines&Mid-Autumn Festival Appreciation Dinner in Langyue Hotel, Foshan, on the evening of September 23, 2020. The guests present were dressed up, men were handsome and women were elegant.
Before the formal start of the dinner party, the company specially prepared the tasting of Italian famous wines for the guests. More than a dozen imported Italian wines with imported Italian cheeses brought different tastes and surprises to the guests, and with the desserts and fruits prepared by the hotel, the guests enhanced their communication while tasting the wine.
At the end of the wine tasting, all guests will be seated. Good wine and delicious food, singing and dancing are ready for tonight's reunion feast.
Song and dance, skit performance, small games, lottery, and special guests came to the stage to dance, and the program was brilliant. Journey to the West "Qi Wei Interview" shows the strength of the company's team through humorous words. Each employee has played a different role in the development of the company, playing a different role, gathering team strength, and building Qiwei brilliant!
Mr. Chen Weitian, the general manager of the company, sang a song "Friends" with the elites of the sales department, which brought the atmosphere to a climax.
An exciting raffle was interspersed in the middle, and the lucky ones were selected from the stage by the wine sponsor, General Manager Luo, and the financial director of our company, Ms. Liu. The prizes were rich.
Sincerity and distance, full of love for the Mid-Autumn Festival! The Mid-Autumn Festival Dinner, a famous Italian wine tasting conference, came to a successful conclusion. Foshan Qiwei Electric Technology Co., Ltd. will work with more automation brands to provide customers with a "one-stop" business platform service of more efficient, fast, professional and honest products+technology+complete solutions.

At present, in the Chinese market, fiber Bragg grating (equipped with ASE broadband light source) and distributed sensor based on optical time-domain reflection are the most widely used optical fiber sensing technologies. This technology can basically meet the needs of the medium and low end general market and is well known by industry insiders. The single-frequency fiber laser with spectral linewidth as narrow as 2 kHz and the latest generation of optical sensing technology introduced now are completely different from the optical fiber sensing we now know. This new technical solution can fully meet the higher demand for ultra-long distance, ultra-high precision and ultra-high sensitivity in the high-end market, which cannot be completed by electric sensing and general optical fiber sensing. However, this technology is still in the stage of project approval and pre-research in China. Compared with traditional sensing technology, fiber-based sensors have the following major advantages: 1. Light weight, compact structure, easy to reuse in multiple ways; 2. Resistance to harsh environment, electromagnetic interference and chemical corrosion; 3. There is no need for electricity at the sensing point, and long-distance distributed sensing is possible; 4. Low cost mass production After optical fiber communication, optical fiber sensing has also ushered in an important development opportunity. It has extensive and huge application value in security, military, oil/gas, electricity and scientific research, especially in western developed countries. The optical principle of single-frequency fiber laser for optical sensing is optical frequency time-domain reflection.MORE +
1. Structure principle of optical fiber sensor The traditional sensor based on electricity is a device that converts the measured state into measurable electrical signals. Its power supply, sensitive components, signal receiving and processing system and information transmission are all connected with metal wires. Optical fiber sensor is a device that converts the measured state into a measurable optical signal. It is composed of optical transmitter, sensing element (optical fiber or non-optical fiber), optical receiver, signal processing system and optical fiber. The light emitted by the optical transmitter is guided to the sensitive element through the source optical fiber. At this time, a certain property of the light is modulated by the measured, and the modulated light is coupled to the optical receiver through the receiving fiber, so that the optical signal is converted into an electrical signal, and finally the desired measured signal is obtained through signal processing. It can be seen that the optical fiber sensor is essentially different from the traditional sensor based on electricity in measuring principle. Traditional sensors are based on mechanical-electrical measurement, while optical fiber sensors are based on optical measurement. Light is a kind of electromagnetic wave, whose wavelength ranges from 1 mm in the far infrared to 10 nm in the far ultraviolet. Its physical and biochemical effects are mainly caused by the electric field. Therefore, when discussing the sensitive measurement of light, we must consider the vibration of the electric vector E of light, namely A - amplitude vector of electric field E; ω—— Vibration frequency of light wave; φ—— Optical phase; T - propagation time of light. It can be seen that as long as one of the parameters such as the intensity, polarization state (direction of vector A), frequency and phase of the light changes with the change of the measured state, or is modulated by the measured state, then the required measured information can be obtained by adjusting the intensity modulation, polarization modulation, frequency modulation or phase modulation of the light. 2. Classification of optical fiber sensors Note: MM multimode; SM single mode; PM polarization maintenance; a. B, c functional type, non-functional type, pickup typeMORE +
The China International Import Expo is a major measure taken by the Chinese government to firmly support trade liberalization and economic globalization and actively open its market to the world. The exhibition covers seven major industries, including service trade, automobile, high intelligent high-end equipment, consumer electrical machinery and equipment. Fuji Electric Co., Ltd. also participated in the exhibition. With the theme of energy and environment business, in the 108 square meters, blue and white Fuji Electric Exhibition Hall, energy optimization and stabilization were carried out; Achieve stable operation and energy-saving effect of the plant; Environmental measurement of air pollution, etc., to the optimal operation of equipment; It also saves labor and people, and provides four displays of food safety and reassurance.MORE +
