A remote digital two-way transmission technology

Abstract

The invention discloses a remote digital quantity two-way transmission technology. The remote digital quantity two-way transmission technology comprises the following steps that: a data collection module in a field device terminal module collects a digital quantity signal at field, the data collection module transmits the collected digital quantity to a data processing module, the digital quantityinformation collected in the data processing module is processed, the data is integrated, and the integrated data is sent to a data analysis module. The present invention relates to the technical field of information transmission. The remote digital quantity two-way transmission technology employs an optical fiber transmission mode different from a mode of using a lot of cables in the prior art,a lot of cables are saved, the construction difficulty is reduced, the engineering cost is reduced, the anti-interference ability is high, the optical fiber transmission has a high ability to resist electromagnetic interference and industrial interference so that the signals transmitted in the optical fiber is not easy to be intercepted to facilitate secrecy, and the later maintenance is convenient in the different from the large workload of the later maintenance by employing a lot of cables.

Description

technical field [0001] The invention relates to the technical field of information transmission, in particular to a remote digital two-way transmission technology. Background technique [0002] Information transmission is to transmit commands or status information from one end to the other end through the channel, and be received by the other end, including transmission and reception. The transmission medium is divided into wired and wireless. The wired is a telephone line or a dedicated cable; the wireless is the use of radio stations, Microwave and satellite technology, etc., the information cannot be changed during the information transmission process, and the information itself cannot be transmitted or received. There must be a carrier, such as data, language, signal, etc., and the transmission and reception aspects have a common interpretation of the carrier. Digital Quantity is a kind of physical quantity. Their changes are discontinuous in time and always occur in a s...
