Low-voltage power line carrier networking communication protocol conversion terminal and conversion method

Abstract

The invention discloses a low-voltage power line carrier networking communication protocol conversion terminal and conversion method, a communication protocol conversion assembly is installed at the inner side of a basic frame, an adjustable heat dissipation assembly is installed at the top end of the basic frame, and the adjustable heat dissipation assembly comprises a frame, a blade plate, a short shaft, a driving gear, a driven gear, a rack, a servo motor and a supporting strip; according to the low-voltage power line carrier networking communication protocol conversion terminal, when the interior of the basic frame is overheated, the servo motor drives the driving gear, and the driving gear is linked with the driven gear through the rack, so that the driven gear and the driving gear can rotate at the same rotating direction and rotating speed, and meanwhile, the two gears can drive the blade plates through the short shafts; the blade plates are closed and opened, the blade plates in the adjustable heat dissipation assembly are located over the communication protocol conversion assembly, heat dissipation of the communication protocol conversion assembly is assisted after the blade plates are opened, and internal dust accumulation can be avoided while the heat dissipation performance of the whole communication protocol conversion terminal is good.

Description

technical field [0001] The invention relates to a communication device, in particular to a low-voltage power line carrier network communication protocol conversion terminal and a conversion method. Background technique [0002] Power line communication technology appeared in the early 1920s. It is a means to use the existing low-voltage distribution network as a transmission medium to realize data transmission and information exchange. When using power line communication to send data, the transmitter first modulates the data onto a high-frequency carrier, and then couples it to the power line through a coupling circuit after power amplification. The peak-to-peak voltage of the signal frequency band generally does not exceed 10V, so it will not cause adverse effects on the power line. [0003] The power line communication technology on the low-voltage distribution network needs a communication protocol conversion terminal. Often, this communication protocol conversion termi...

Problems solved by technology

[0003] The power line communication technology on the low-voltage distribution network needs a communication protocol conversion terminal. Often, this communication protocol conversion terminal will generate a large amount of heat at a certain moment of work and needs to be dissipated in time. Therefore, an auxiliary tool with good heat dissipation is required. The existing In order to ensure heat dissipation, the communication protocol conversion terminal will have large-sized cooling holes on the body, but it is prone to dust accumulation
