[Abstract]:Digital video optical terminal (DVOT) is an indispensable transmission equipment in the monitoring system, and its products have always been an important part of the monitoring product line of our company. To further meet market demand, the company has developed a low-cost, high-stability optical terminal to upgrade its products. The designed digital video optical terminal is composed of two parts: receiver and transmitter. The remote transmission of information is realized through the mutual conversion of photoelectric signals. The paper elaborates the hardware composition and software design of the optical terminal developed by this project. The hardware part mainly designs the video acquisition module, the video receiving module, the data sending and data receiving module, the photoelectric, electro-optic conversion module and the CPLD data processing module of the core part. The software part makes full use of the flexible programming characteristic of CPLD chip and realizes the fast lossless transmission of remote data through the principle of time division multiplexing (TDM) technology. Most of the circuits used in this design are integrated chips, which not only reduce the cost but also increase the stability of the system. It is also very convenient to detect and debug in the later production process. The core processing module uses CPLD chip, the CPLD chip is cheap, the coding and debugging is convenient, and the application interface is flexible enough to meet the complex system requirements with simple hardware circuit. We developed two video and one data optical machine in the product comprehensive quality has a big breakthrough, reached the international similar products advanced level, for the company in time to provide competitive products.
