The intelligent magnetic levitation direct drive door machine system developed by the Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences, has been operating continuously for nearly 1 year in the major projects of large-scale treasury guards in Shaoxing Anbang, successfully realizing commercial applications.
The system adopts a magnetic levitation direct drive door machine technology independently developed by Ningbo Material Institute, and a number of innovative technologies such as vehicle entry and exit intelligent management and control technologies. It consists of 4 sets of magnetic levitation direct drive door machines and 1 set of vehicle entry and exit intelligent control systems. Among them, the magnetic levitation direct drive door single door maximum travel is more than 4.0m, the total weight of the single door mobile part is more than 900Kg, and the maximum door opening speed is more than 1.5m/s. According to the international investigation of the national first-grade checking agency, the door The machine technology index is the international leader and the structure is the first in the world.
The vehicle enters and exits the intelligent management and control system. It has a variety of automatic, semi-automatic and manual operation modes. It is equipped with a vehicle identification device that can automatically read the vehicle information and intelligently determine the access permission of the vehicle. It has a multi-level obstacle detection device and stroke limit. The device can effectively prevent the high-speed moving door from hitting a pedestrian or a vehicle. It has an efficient and reliable anti-kick-in and anti-following function, which can effectively prevent illegal vehicles from entering or being forced into the vehicle. Relevant core technologies have applied for invention patents, and some patents have been authorized, and a corresponding portfolio patent protection system has been formed.
Due to the adoption of a magnetically levitated direct drive structure, the door machine system can effectively solve the technical problems of track wear and speed limitation in two major industries at the same time. It can be applied to various strokes, speeds, and loads, and has a wide range of application fields, especially in heavy loads. Long-range applications show unique advantages. The warranty period of this magnetic suspension direct drive door machine system can reach 5 years, which is much higher than the one-year warranty period of similar products. It also has the characteristics of resistance to vehicle's illegal forced impact (it will not be stuck after forcible impact, only the door body must be corrected. Normal work can be done. There is no problem of easy jamming and difficult repair of similar products after unfair forcible impact.
In order to promote the industrialization and commercialization of magnetic suspension direct drive door technology, Ningbo Materials has developed the "Q/CNITECH 002-2015 magnetic suspension direct drive door machine" standard and passed GB/T 19001-2008 and ISO 9001. : 2008 international quality system certification, and third-party type testing of China Inspection & Certification Group.
The successful commercial use of the intelligent magnetic levitation direct-drive door machine system of Ningbo Materials Institute indicates that China has made major breakthroughs in the field of high-end automatic door machines and is conducive to breaking the situation in which high-end automatic door machines depend on imports. The technology can also be applied in the field of high-end CNC machine tools, laser cutting, precision measurement and other intelligent manufacturing equipment, and plays an important role in driving the development of related industries such as magnetic materials, linear motors, intelligent control, and equipment manufacturing.
