Abstract

The invention provides an audio and data forwarding device with multiple transmission means based on a compact peripheral component interconnect (CPCI) bus. The device comprises a CPCI bus, an interface module, a main control module, a wired modulation module and a wireless modulation module, the interface module, the main control module, the wired modulation module and the wireless modulation module are connected with the CPCI bus, and the main control module controls the wired modulation module and the wireless modulation module to modulate signals input by the interface module and to forward the modulated signals in a wired mode and a wireless mode respectively. The forwarding device has multiple transmission means of audio and data signals, the transmission mode is reliable, and the transmission distance is far.

Description

technical field [0001] The invention relates to the field of electronic circuit design, in particular to a CPCI bus-based audio and data forwarding device with multiple transmission means. Background technique [0002] In short-wave communication, after the receiver demodulates the audio and data, it needs to send the data to the information center through the transmission equipment. In some occasions in the past, using ordinary audio cables to realize signal transmission has relatively simple means and poor invulnerability. The development of various networking technologies such as Ethernet, Wimax, and Wifi provides a basis for realizing various transmission methods. Among them, wireless Wimax is a large-capacity, high-speed, and wide-coverage communication technology based on the IP protocol. Wifi is also the most widely used wireless network transmission technology, with wide coverage of radio waves and fast transmission rates. Contents of the invention [0003] The p...
