Abstract

The invention provides a wireless keyboard and mouse receiving and transmitting device comprising a transmitting part and a receiving part. The transmitting part comprises a PS2 interface for being connected with a keyboard and a mouse, a transmitter processor and a wireless transmitter module, keyboard information and mouse information are transmitted to the transmitter processor through the PS2 interface, coded by the transmitter processor to form coding information which is transmitted to the wireless transmitter module for wireless transmission. The receiving part comprises a wireless receiving module, a receiving processor and a USB interface for being connected with a host, bidirectional series communication is established between the wireless receiving module and the wireless transmitter module, and the coding information transmitted by the wireless transmitter module is received by the wireless receiving module and then transmitted to the receiving processor which converts the keyboard information and the mouse information acquired by decoding the coding information into HID (Host Interface Device) data format and transmits the information to the host through the USB interface. The invention realizes that the PS2 (Play Station) mouse information and the keyboard information are collected, coded, transmitted and received in a wireless mode.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a wireless keyboard and mouse transceiver. Background technique [0002] The 27MHz RF technology adopted by the existing wireless keyboard and mouse (referred to as wireless keyboard and mouse) has an operating range of only 1.8 meters, and similar products are prone to interference problems; Bluetooth technology can achieve an effective distance of 10 meters, but due to the payment of patent fees, The cost of products using Bluetooth technology will increase by an additional 3-5 dollars. 2.4G wireless technology solves the shortcomings of 27Mhz high power, short transmission distance, and mutual interference between similar products. The transmission rate reaches 2Mbps, and supports automatic frequency modulation. The two-way transmission mode also completely eliminates the occurrence of signal interruption, making the development of 15 It is possible to use a wi...
