Warmly congratulate Foshan Qiwei Electric Technology Co., Ltd. on joining the Guangdong Food and Packaging Machinery Industry Association
A new chapter of manufacturing towards digitalization, networking and intelligence
On December 29, 2020, Foshan Qiwei Electric Technology Co., Ltd. joined Guangdong Food and Packaging Machinery Industry Association
Foshan Qiwei Electric Technology Co., Ltd., the manager of Zhaojincheng, made a speech
On December 29, 2020, Foshan Qiwei Electric Technology Co., Ltd. joined the Guangdong Food and Packaging Machinery Industry Association Guangdong Food and Packaging Machinery Industry Association, an industrial group and social group legal person approved by the Provincial Department of Civil Affairs (Yue She Zheng No. 0690) in 1992, and is a provincial cross-sectoral food machinery, packaging machinery and corresponding upstream and downstream enterprise industry organization Enterprises and institutions, scientific research and design institutes, colleges and universities, and relevant associations in the industry of food machinery and related machinery are voluntarily formed, with more than 100 group members.
The first general meeting of the seventh session and the first (expanded) meeting of the seventh session of the Guangdong Food and Packaging Machinery Association
For many years, the Association has actively organized and carried out various service activities, such as industrial technical exchanges, seminars, application and evaluation of industrial technical projects, application of intellectual property rights, customization and revision of industrial standards, famous trademarks and famous-brand products, etc., participated in various appraisal meetings, acceptance meetings, achievement evaluation, etc., participated in bidding and tendering work, carried out training activities, foreign affairs activities, held exhibitions, edited and published information publications, Provide information consulting services, etc. The Association maintains business relations with domestic and foreign industrial organizations. Since 1991, the Association has held or participated in national and international trade exhibitions in Guangzhou every year to help enterprises develop domestic and foreign markets, and has become an influential trade fair and technical exchange exhibition in the industry in South China, which has been welcomed by the industry and people from all walks of life.

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 +
