With the progress of the construction of Beidou system in our country and the further improvement of satellite navigation and positioning accuracy requirements, high-precision satellite navigation applications have gradually penetrated into many fields such as safety detection, fine agriculture and smart city from the traditional surveying and mapping fields. The subject aims at the urgent need of high-precision positioning equipment and service system in the areas of fine urban management, large-scale structure monitoring, geological environment monitoring, agricultural delicacy management, national forest protection and other areas. A high-precision GNSS reference station receiving Machine and a variety of mobile application terminals to build a constellation-compatible high-precision location service system; in the high-precision Beidou multi-mode multi-frequency card technology, based on Beidou's CORS distribution site management and data processing technology, high-precision Beidou real-time displacement monitoring Platform architecture and other key technologies to achieve a breakthrough.
The research achievements of the project are as follows: Health monitoring of large structures such as the East China Sea Bridge, Huangpu Bridge, CCTV and Shenzhen Ping An Financial Center and other large structures such as super-high-rise buildings and long-span bridges, agricultural operation areas such as Jian Sanjiang Farm in Heilongjiang Province, Animal Husbandry and Animal Husbandry, Nature Reserve animal monitoring and management, etc. In addition to the successful application of the high-precision location information service system in Shanghai, the project has been gradually applied to the domestic provinces and overseas regions such as Qinghai, Fujian, Shandong, Hebei, Zhejiang, Sichuan and Jilin in the recent two years.
The Beidou agricultural autonomous navigation system developed by the project has been widely used in Heilongjiang and Xinjiang. The automatic navigation system of Beidou of agricultural machinery has been installed more than 2000 units in total. By using Beidou navigation satellite automatic driving precision sowing technology, various types of prime time are effectively promoted Sowing of crops, reducing the driver's labor intensity, improving work efficiency by 50% and saving 20% ​​of the land. Sowing per kilometer error 2.5 cm, 30 yuan per mu of land. It has effectively promoted the application of BeiDou in the field of fine agriculture, greatly promoted the promotion of BeiDou in the process of agricultural modernization, and laid a solid foundation for further promoting the extensive application of BeiDou high-precision satellite navigation in China.
H-beam is a kind of economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named after its section is the same as the English letter "H". Since all parts of H-beam are arranged at right angles, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used.
