Embodiment Construction

[0020] see figure 1 , is a schematic diagram of the first embodiment of the control device of the free-space optical communication system of the present invention. The control device 1 of the free space optical communication system includes: a single chip microcomputer serial port 10 , an electrical interface 12 and an optical interface 15 . The functions and characteristics of the free space optical communication system determine that it must have an on-site installation and commissioning process. During debugging, some internal information of the free space optical communication system may need to be reconfigured, and some debugging instructions may need to be executed. At this time, local management is required. We use the standard hyperterminal program in the windows operating system as the management software. At this time, the single-chip serial port 10 is connected to the electrical interface 12 through the RS-232 level conversion device 11 . After commissioning, remo...

Abstract

This invention discloses controller of free space optical communications system, which contains optical interface, electric interface and communication which connected with electric interface by an electric level converter in local management, in long distance management, said communication interface in turn connected with optical interface by amplifying driving device and electric-optical converter. Said invention also discloses a control method for free space optical communications system. Said invented controller not only can solve thunder leading problem but also reduce cost by adopting the electric and optical interface combination mode.

Description

【Technical field】 [0001] The present invention relates to a control device and method of a data communication system, in particular to a control device and method of a Free Space Optics (Free Space Optics, FSO) system. 【Background technique】 [0002] Traditional communication systems that use cables to connect two or more locations are generally limited to relatively low-speed, low-capacity applications. To overcome these limitations, in recent years, systems have been developed that use optical fibers. However, fiber still requires the use of physical connections. To address this problem, systems have been developed that utilize free space to emit one or more data-modulated beams. Systems using such beams can be installed flexibly, while avoiding the infrastructure costs of laying fiber optic cables to physically connect various locations in the system in traditional communication systems. [0003] Free space optical communication technology is a wireless transmission tec...
