【概要描述】The years have changed, and the four seasons have come back. The beauty of 2020 has not yet disappeared, and 2021 has quietly arrived. On January 27, 2021, our company held the 2020 year-end conference and the Spring Festival dinner.
The years have changed, and the four seasons have come back. The beauty of 2020 has not yet disappeared, and 2021 has quietly arrived. On January 27, 2021, our company held the 2020 year-end conference and the Spring Festival dinner.
Next, Ms. Liu Jie, the financial director of our company, Mr. Chen Lisheng, the general manager of sales, and other department heads all summarized the work of our department in 2020, and also made detailed arrangements for the work of our department in 2021.
After the end of the annual meeting, we welcomed the exciting Spring Festival dinner that we are all looking forward to!
After Mr. Chen Weitian, the general manager, delivered a speech and toasted the dinner, the banquet officially opened.
Due to the epidemic, only some suppliers and core partners were invited to join us for dinner, with the participation of leaders from Schneider, Siemens, Eaton, Italian M.D., and Shenzhen E-Energy. Get their support and encouragement!
Next is the indispensable excellent employee award and sales outstanding award. Ms. Liu Jie, the chief financial officer, and Mr. Chen Weitian, the general manager, respectively issued honorary certificates and bonuses to the award-winning colleagues. A share of cultivation, a share of harvest, and efforts will eventually yield success!
In the easy and funny game, we also invited guests to play with us.
Together, build a dream for the future! Foshan Qiwei Electric Co., Ltd.'s 2020 year-end conference and Spring Festival Dinner concluded successfully. Clear the past, and everything will be updated. In 2021, ride the wind and waves, set sail, and be fearless!

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.

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 +
