  • Detail

Sensor technology has entered the field of food detection. With the arrival of the new technological revolution, the world has begun to enter the information age. In the process of using information, the first thing to be solved is to obtain accurate and reliable information, and sensors are the main ways and means to obtain information in nature and production fields. In modern industrial production, especially in the process of automatic production, various sensors should be used to monitor and control various parameters in the production process, so that the equipment can work in a normal state or the best state, and the products can achieve the best quality

in the 12th Five Year Plan, China's industrial output value will increase by an average of 20% annually. RFID tags will increase by about 21% annually in the next five years. IOT applications have entered the market introduction period from government policy support. As the basis of IOT, sensors are at the upstream of the industrial chain and benefit greatly from the development of IOT at the beginning. However, sensors have become the bottleneck of the development of IOT in China

according to the analysis, the development of China's sensor industry is backward, the domestic sensor demand, especially the high-end demand, is heavily dependent on imports, and the localization gap is huge. At present, the import of sensors accounts for 80% and the import of sensor chips accounts for 90% There is an urgent need for localization

sensor technology has entered the field of food industry

it is understood that at present, integrated circuit detectors have been widely used in foreign food processing plants, and this technology can detect the deterioration time of food. The food quality inspection configuration is mainly composed of a scanner and a sensor. As long as the scanner is aimed at the food and emits a radio wave signal, the food will vibrate and form a music score wave, which will be transmitted to the sensor

among machine vision products, color machine vision products have been applied in food detection, mainly judging the maturity and quality level of food by its color. In addition, the application of wireless sensor networks is also popularized rapidly. Large foreign food processing plants have applied this technology to the system of collecting food information and ensuring food safety, which is one of the goals of alloy composition design and microstructure control. Through the networking function of wireless sensors, consumers can better understand the whole process of food production, storage and transportation in food processing plants, making food processing more intuitive and transparent, which can effectively dispel consumers' concerns about food safety. At the same time, in the case of problems, the wireless practice results show that the sensor technology also facilitates the regulatory authorities to find problems in time, and make it well documented to curb food safety problems from the source

motion control system is the key to the development of food packaging machinery in China, and the technology is becoming more and more mature. Motion control technology in food packaging machinery mainly realizes the accurate control of position, and strictly requires the synchronization of speed. It is applied to food transportation, loading and unloading, stacking without black smoke, unloading, marking and other procedures. Through the application of motion control technology, high, medium and low-grade packaging machinery can be effectively divided, which plays a vital role in the upgrading of food packaging machinery in China. The mechanical assembly line of food packaging has continuity, so it puts forward higher requirements for its speed, accuracy, dynamics and torque, which just conforms to the characteristics of products

therefore, the bus type motion controller proposed in the current automation technology has a broad development prospect in the food packaging industry. With the high-speed bus communication mode, it can realize the functions of high-speed tracking, converting multiple position control modes, and exchanging data information of multiple communication ports. In addition, China's food packaging machinery is correspondingly facing the process of changing from labor-intensive to knowledge intensive. Managers of enterprises should also pay more attention to motion control technology, so as to reduce production costs and improve food packaging quality

China's sensors must achieve breakthroughs in localization, application and technology in order to have a certain position in the international sensor market and realize the accelerated development of the IOT industry
