Problems solved by technology

[0002] With the development of science and technology, the demand for communication networks continues to increase. From smart cities, the Internet of Things to various wearable devices, the demand for data transmission rate and transmission quantity is also constantly improving. Full duplex refers to the communication network. At any time, there is two-way signal transmission from A to B and B to A on the line, which can effectively improve the transmission efficiency of data; in full-duplex mode, each end of the communication system is equipped with a transmitter and a receiver, therefore, It can control data to be transmitted in two directions at the same time; this method requires both parties to have a transmitter and a receiver, and at the same time, two data lines are required to transmit data signals; for small wearable devices, full-duplex communication is often There is a problem of high power consumption and high power consumption, which cannot meet people's needs for low power consumption of the Internet of Things. At the same time, there is a problem that the receiver is easily interfered by the transmitter

Abstract

The invention provides a full-duplex data communication device, which comprises a filter circuit, an interference elimination circuit, a receiving antenna, a transmitting antenna, a combiner, a power divider, a receiving frequency mixer, a central processing unit, a transmitting frequency mixer and a power supply. The output end of the receiving antenna is connected with the input end of the interference elimination circuit, the output end of the interference elimination circuit is connected with the input end of the filter circuit, the output end of the filter circuit is connected with the input end of the combiner, the output end of the combiner is connected with the input end of the receiving mixer, and the output end of the receiving mixer is connected with the input end of the central processing unit. The output end of the central processor is connected with the input end of the transmitting mixer, the output end of the transmitting mixer is connected with the input end of the power divider, the output end of the power divider is connected with the input end of the transmitting antenna, and the power supply is connected with the central processor. According to the invention, the interference of the signal transmitted by the transmitting antenna on the signal received by the receiving antenna can be effectively reduced, so that the accuracy of the signal received by the receiving antenna is higher.
