MOXA Telecommunication Equipment Network Management
Chongqing Communications Equipment Co., Ltd. has more than 40 years of history. The existing staff of 1600, total assets of 700 million yuan, the company's headquarters under a national-level enterprise technology development center, three production plants, seven holdings or joint ventures, is a Sino-foreign joint venture large-scale high-tech enterprises. The company's products are widely used in China's public and private communications network and defense industry, education and scientific research, public security, meteorology, enterprises, radio and television and other sectors, covering 30 provinces, municipalities and autonomous regions, and exported to Russia, North Korea, Nepal, Bangladesh, Jordan and other countries.
In this system, users have developed a set of network equipment management systems to manage telecommunications equipment distributed throughout the country. This system abandons the previously wasted solution of managing the waste of resources of a field device through a computer, solves the difficulty of the user's management of telecommunication equipment in different places, realizes centralized management and remote maintenance of equipment, and greatly facilitates management and maintenance, and provides customers with The best system solution.
The size of the NPort Express Module DE-311M is only the size of a credit card, and it can be directly connected to the board level using RS-232 or TTL level for telecommunications equipment. It can be installed inside the telecommunications equipment, enabling the original telecommunication equipment to achieve immediate networking capability. Centralized remote device management over the network.
Vacuum fluorescent display, referred to as VFD, is a low-energy electroluminescent display devices, the working principle and CRT similar. It has the incomparable advantage of liquid crystal display (LCD) in applications where there is a large variation in ambient brightness and no strict requirement for low power consumption, and is now widely used in audio-visual equipment, home electronics, automotive instruments, office equipment and instrumentation.
The structure of a VFD board is a typical vacuum triode structure, consisting of a cathode, a grid and an anode. In between the cathode and the anode there's a thin mesh of metal called the Grid that can be switched on or off, controlling the flow of electrons from the cathode to the anode. This VFD grid mesh is made of a thin metal plate with a thickness of 30 to 50μm, which is lithographed and made into a highly transparent fine lattice or tortoise-shaped metal mesh. When a positive voltage is applied to the grid, electrons emitted from the filament are accelerated and diffused toward the anode. When a negative voltage is applied to the grid, electron flow to the anode is cut off.
We custom VFD Grid with drawings provided by customers. The raw material we use for etched VFD Grid is SUS430 stainless steel. We are equipped with professional metal etching equipment and exposure development equipment. Our etched manufacturing capacity can achieve 0.05mm.
