Abstract
The invention discloses a small-hydropower-station key information monitoring terminal based on a Beidou satellite. A master station serving as a collecting terminal, a plurality of substations and a communication data protocol converter are installed in a small hydropower station, wherein the substations are in charge of collecting electric energy of a multifunctional electric energy meter and analog quantity signals of three-phase alternating voltage and three-phase alternating current of secondary sides of a PT and a CT of each machine set. The master station is respectively connected with each substation and the communication data protocol converter, the communication data protocol converter converts information collected on the electric power site into Beidou satellite data information and then uploads the Beidou satellite data information to a Beidou subscriber's machine in an RS-422 communication mode, the Beidou subscriber's machine sends the Beidou satellite data information to a communication process layer through Beidou satellite communication, and the Beidou satellite data information is received by a Beidou satellite receiving terminal and displayed on an information management platform in real time. The information collected on the electric power site is converted into the Beidou satellite data information through the communication data protocol converter, seamless connection between an electric power site sensor and the Beidou satellite communication is achieved, and key information monitoring of the small hydropower station is achieved.
