Plastic optical fiber network electricity checks meter system

Abstract

The invention provides a plastic optical fiber network electricity checks meter system, and belongs to the field of power line information transmission. The checks meter system provided by the invention has strong anti-electromagnetic interference and nuclear radiation resistance as well as reliable performance; collected data has strong real-time performance, and low cost and high speed transmission of data are realized; the plastic optical fiber network electricity checks meter system is composed of electricity meters, a meter reading module, plastic optical fiber, a plastic optical fiber network switch and a data processing center; The signal flow direction of the checks meter system is as follows: an optic transmitter of the meter reading module converts an electricity meter signal to a network optical signal; the optical signal is coupled to the plastic optical fiber; an optical receiver of the meter reading module receives signals and reduces the optical signal to a network electrical signal; the plastic optical fiber network switch is used for data processing; and the data processing center is used to process data so as to complete the whole process of meter reading. The checks meter system provided by the invention has excellent anti-electromagnetic interference performance, strong security, high sensitivity and small volume, is simple to prepare, requires low cost, and has waterproof and moistureproof properties as well as long service life.

Description

technical field [0001] The invention belongs to the field of information transmission on power lines, and in particular relates to a plastic optical fiber network power meter reading system. Background technique [0002] The existing power remote automatic meter reading system adopts a two-level reporting mechanism. The first level is from the meter to the concentrator, and the transmission method is RS485 and 220V power carrier; the second level is from the concentrator to the power management center, and the transmission method is wired local telephone. network, broadband metropolitan area network, GPRS, wireless communication network and 10kV power line carrier network. The bipolar reporting mechanism adopts a concentrator connection between the electric meter and the data processing center, which increases the volume and manufacturing cost of the meter reading system, and the reading and control of data are affected by the concentrator. [0003] Except for the power lin...
