Wireless Bluetooth adapter suitable for portable terminal

Abstract

The invention discloses a wireless Bluetooth adapter suitable for a portable terminal. The wireless Bluetooth adapter comprises a power conversion circuit, a signal conversion circuit and a transceiver, and is used for establishing serial port communication or wireless Bluetooth communication between a test instrument and the portable terminal. The wireless Bluetooth adaptor is arranged on a serial port interface, and the test instrument supplies power to the wireless Bluetooth adapter through the serial port interface. The advantages are as follows: wireless communication with the portable terminal can be realized without changing the test instrument, and non-paper office working is realized; and operators can also switch between the serial port communication and the wireless Bluetooth communication, the operation is simple and convenient, and the wireless Bluetooth adapter is little influenced by environment and has quite high practicality.

Description

technical field [0001] The invention relates to an adapter, in particular to a wireless bluetooth adapter suitable for portable terminals. Background technique [0002] With the continuous development of information technology, the new paperless office model will gradually replace the traditional file transfer office model, and in order to actively respond to the country's overall policies on low-carbon, environmental protection, energy saving, and paperless office, the country has established a set of A paperless office system that is compatible with existing instruments and equipment to improve office efficiency. [0003] At present, most instruments establish communication with computers through serial ports. In field use, they are often limited by the length of wiring and communication lines, which makes it very inconvenient to use. Due to the rapid development of portable terminal technologies such as tablet computers, the functions are becoming more and more perfect, a...
