Abstract

A conversion device converting heterotype serial data into standard asynchronous communication waveform comprises an input module, a judging module, a processing module and an output module which are arranged inside a singlechip and are connected in series, as well as an interrupt processing module, wherein the input end of the interrupt processing module is connected with the other output end of the processing module, while the output end is connected with the output module. The conversion device completes reshaping of low level data waveform through the interrupt processing module, thereby realizing the conversion of the entire waveform and effectively overcoming the disadvantage that the waveform signal formed during bus transmission can not be directly received by a singlechip port; meanwhile, the data output end of the data receiver arranged inside a data transceiver is simply connected with the periphery of the singlechip, which omits the complex connection of peripheral circuit and is propitious to product integration. The invention also designs a method for waveform conversion.

Description

technical field [0001] The invention relates to a waveform conversion device, in particular to a conversion device based on special-shaped serial data generated by a specific bus transceiver to a standard asynchronous communication waveform. Background technique [0002] Aiming at the technical problem that the current industrial fieldbus cannot take into account the transmission distance, transmission rate, resource utilization and cost at the same time, the applicant provides a bus data transceiver to receive and send digital signals, see the application number: 200710178354.5, A patent application for an invention entitled Bus Data Transceiver. At the same time, in order to realize the continuous low-level signal, the applicant provided a digital data formation method, see the application number: 200710178430.2, the invention patent application named the digital data formation method for bus transmission, but this digital data formation method The logic waveform is a non...
