Technical Field

The invention relates to the technical field of electric power, in particular to an uplink channel photoelectric transmission system of an electric energy acquisition terminal.

Background

With the continuous promotion of the construction engineering of the power utilization information acquisition system, at present, the uplink channel of the electric energy acquisition terminal of the transformer substation is mainly transmitted by the traditional network cable, the transmission mode has larger signal attenuation when transmitting long-distance signals, and the transformer substation is not allowed to be replaced by a wireless transmission mode based on the information confidentiality requirement of the transformer substation, so that the acquisition success rate is low and unstable, the line is frequently dropped, the acquisition index is influenced, and the field maintenance is greatly troublesome.

Disclosure of Invention

The invention aims to: the invention provides an uplink channel photoelectric transmission system of an electric energy acquisition terminal, which solves the technical problems of low acquisition success rate and instability caused by the fact that the uplink channel of the existing electric energy acquisition terminal adopts network cable transmission.

The technical scheme adopted by the invention is as follows:

an uplink channel photoelectric transmission system of an electric energy acquisition terminal comprises an acquisition terminal side and a comprehensive data network side, wherein the acquisition terminal side comprises the electric energy acquisition terminal for acquiring electric energy of a transformer substation, and the acquisition terminal side and the comprehensive data network side perform data transmission through optical fibers;

the side of the acquisition terminal is also provided with an optical fiber modulator used for converting the electric energy data into optical signals;

the comprehensive data network side is also provided with an optical fiber demodulator for converting the optical signal into an analog signal;

and the two ends of the optical fiber are respectively connected with the optical fiber modulator and the optical fiber demodulator, so that the long-distance transmission of optical signals is realized.

Furthermore, an ethernet converter a is further arranged at the acquisition terminal side, the ethernet converter a is connected to the electric energy acquisition terminal through a network port, and the other end of the ethernet converter a is connected to the optical fiber modulator, and is used for transmitting the electric energy data to the optical fiber modulator through an E1 transmission circuit.

Furthermore, the side of the acquisition terminal is also provided with a switch A, one end of the switch A is connected with the optical fiber modulator, and the other end of the switch A is connected with the optical fiber.

Furthermore, the comprehensive data network side is also provided with an ethernet converter B, one end of the ethernet converter B is connected with the optical fiber demodulator, the other end of the ethernet converter B is connected with the main control terminal, and the analog signal is transmitted to the main control terminal through an E1 transmission circuit.

Furthermore, the side of the acquisition terminal is also provided with a switch B, one end of the switch B is connected with the optical fiber demodulator, and the other end of the switch B is connected with the optical fiber.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

the invention changes the traditional transmission mode that the electric energy acquisition only depends on the network cable as an uplink channel, greatly reduces the intermediate loss of signals in the process of long-distance transmission and effectively improves the acquisition success rate.

The signal transmission of the invention still takes the wired transmission as a means, and the signal interference to the transformer substation system can not be caused after the transformation.

The invention initiates an uplink channel optical fiber transmission mode for collecting electric energy, and basically realizes signal transmission zero loss by replacing a network cable with optical fibers.

The on-line stability of the terminal is also greatly enhanced after the uplink channel of the electric energy acquisition terminal adopts photoelectric transmission.

The invention has strong adaptability and can be suitable for almost all substations at present.
