Touch screen terminal and communication system and method based on human body electric field conduction

Abstract

The invention is suitable for communication field and provides a touch screen terminal. The touch screen terminal comprises an electrode unit, a working mode switchover unit, a main control unit and a communication information processing unit. The electrode unit is used for transmitting and receiving signals during human body communication and can form the human body electric field signal circuit together with a human body, an external human body communication device and the ground during the human body communication, the working mode switchover unit is used for setting a touch operation mode or a human body communication mode of the touch screen terminal in work, the main control unit is connected with the working mode switchover unit and the electrode unit and is used for receiving and transmitting communication information through the human body electric field signal circuit in the human body communication mode, and the communication information processing unit is used for processing the communication information received by the main control unit through the human body electric field signal circuit, processing the information to be transmitted and transmitting the information through the main control unit and the human body electric field signal circuit. The touch screen terminal is based on a capacitive touch screen technology, can finish human body communication transmission without complicated sensors and hardware, can multiplex an electrode structure and is easy to popularize and use.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a touch screen terminal, a communication system and a communication method based on human body electric field conduction. Background technique [0002] Portable consumer electronic products such as MP3 players, PDAs (Personal Digital Assistant, personal digital assistants), earphones, etc. have developed rapidly in the past ten years. Information exchange between these portable consumer electronic products and other electronic devices The necessity is becoming more and more obvious. In order to avoid cumbersome wired cables, it is necessary to establish a wireless communication network for these electronic devices. HBC (Human Body Communication) is a new short-distance wireless communication method suitable for all sensor devices on the surface of the human body and inside that can be in contact with the human body. The concept of HBC was first proposed by Zimmerman of the...
