Abstract

The invention discloses a multi-service bus transmission system based on FSK modem. The multi-service bus transmission system comprises a plurality of device nodes. Each device node comprises a bus transmitter and a user information access unit connected with the bus transmitter through a user interface. Each bus transmitter comprises a control assembly for controlling each medium connected with a bus to realize information access, and an FSK modem unit in communication connection with the control assembly; and each bus transmitter is in communication connection with each device node through an external bus to form a multi-service bus transmission communication link. According to the multi-service bus transmission system and data transmission method based on the FSK modem, field bus transmission technology based on an FSK modem mode is provided, and the system has the function of realizing bus transmission in twisted pairs, and meanwhile, has the advantages of long transmission distance, low device power consumption, good real-time performance and high bandwidth and the like.

Description

technical field [0001] The invention belongs to the field bus transmission device technical field of a wired communication system, and specifically relates to the flexible construction of a multi-service bus transmission system based on FSK modulation and demodulation based on IP data, voice, control and other services in a twisted pair transmission medium environment and transmission method. Background technique [0002] Bus transmission is a kind of on-site information transmission with shared transmission medium, which provides users with a shared information transmission platform and realizes information delivery of multi-point access. [0003] With the development of information technology, especially in the field of bus transmission technology, it is required to realize the field bus transmission technology with long distance, low power consumption, anti-interference and strong real-time performance. In the contemporary field of bus transmission technology, the main r...
