Embodiment Construction

[0010] The specific embodiments of the present invention will be described in further detail below.

[0011] The power carrier terminal transformer of the present invention includes two main windings connected in series and a secondary winding. The secondary winding is connected in series with a third capacitor and a load resistance is connected in parallel. The common end of the two main windings is connected to the ground. Two-way voltage stabilizing diode, a filter capacitor is connected between the non-common ends of the two main windings.

[0012] The power carrier communication network generally adopts the master-slave control mode, with a master CPU in the upper layer and several slave CPUs in the lower layer. The master control CPU issues instructions to each slave CPU to coordinate work, and only one CPU can use power line resources at a time. The main control CPU is connected with the gateway or the home server, and the slave CPU controls the operation of the intelligent...

Abstract

A power line carrier wave terminal transformer comprises two series-connected main windings and an auxiliary winding. The auxiliary winding and a third capacitor are connected in series, and are connected in parallel with a load resistor. A bidirectional voltage regulator diode is connected between the common end of the two main windings and the ground. A filter capacitor is connected between the non-common ends of the two main windings. Specifically, the turn ratio of the two main windings is 4-7:1. Specifically, the auxiliary winding has the same number of turns as the main winding with a smaller number of turns among the two main windings. The power line carrier wave terminal transformer of the invention comprises a small number of components, is stable and reliable, can resist various common grid interferences, and is easy to implement.

Description

Technical field [0001] The invention belongs to the field of electronic communication and relates to a power carrier terminal transformer. Background technique [0002] Power Line Carrier Wave (PLCW) communication is a communication method that uses power lines for information transmission. Power line carrier communication is widely used in the automatic collection and transmission of remote three meters (water meter, electric meter, gas meter) information, and is favored in the construction of smart communities. With the development of information technology, intelligent networked home appliances have gradually become a research hotspot, and the application of power carrier to the control of intelligent networked home appliances has just begun. There are no research reports on power carrier communication products applied to the control of intelligent network home appliances in China; [0003] There are still many technical difficulties in applying power carrier to the control of...
