Abstract

The invention discloses a power supply and communication circuit based on two direct current lines and a method thereof, the circuit comprises a sending unit and a receiving unit, the sending unit comprises a direct current power supply circuit and a signal modulation circuit, and the receiving unit comprises a signal demodulation circuit and a power supply reduction circuit; the positive output end and the negative output end of the direct-current power supply circuit are connected with the two input ends of the signal modulation circuit respectively. The two differential output ends of the signal modulation circuit are connected to the differential input end of the signal demodulation circuit through a first power line and a second power line respectively and connected with the two input ends of the power supply reduction circuit. The signal modulation circuit modulates the digital communication signal to a direct-current power supply output by the direct-current power supply circuit to form carrier power supply signal output; the signal demodulation circuit receives the carrier power supply signal and demodulates the carrier power supply signal to collect a digital communication signal; according to the invention, on the basis of the two power lines, power supply transmission and information transmission are satisfied.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a DC two-wire power supply and communication circuit and a method thereof. Background technique [0002] Electronic technology has been widely used in various industries, but almost all products on the market are active. Due to the increase in the functions of electronic products, higher requirements must be placed on the control circuit. The low-voltage DC power supply lines and communication lines between the various modules of equipment and products need to be connected independently. The control between the existing functional modules adopts a multi-board structure. The communication methods between the boards mainly include infrared, RF modules and Various multi-bus methods. However, the lines of these communication methods are relatively complicated, and the manufacturing cost is high. Moreover, due to the limited data to be transmitted between electronic products or ...
