Description
Technical field
The utility model belongs to the control system technical field, is specifically related to a kind of FCS Fieldbus Control case based on the Profibus bus that connects master control and remote scene smart machine.
Background technology
Fieldbus is the communication system of digital, two-way, the multistation of connection of intelligent field apparatus and automated system.Mainly solve digital communication and the information problem of transmission between these field control equipment and the advanced control system (ACS) between the field apparatus such as intelligent instrumentation, controller, topworks of industry spot.
Got into since the new century, along with the fast development of infotech and network technology, people are transmitted the signal between scene and the control system and are had higher requirement.People's this demand has exactly been catered in the appearance of field bus technique.
The transmission system that originally is the basis with the 4-20mA standard is merely able to transmit a signal, or measured value or controlling value, does not have other information except that this.Whether but this quality of signals is how, for example make signal show as maximal value or minimum value because of short circuit or short circuit, so or mechanism has produced bigger deviation etc. owing in signals transmission, disturbed, these information all can't embody.Though the standard of 4-20mA is having very big improvement than the standard of 0-10mA aspect short circuit or the short-circuit detecting, its ability understanding is limited.In addition, except that measuring and information transmission controlling value, like the parameter of the diagnostic message of field apparatus itself, controlled device with move too information etc., the 4-20mA standard is helpless fully for the scene.
Along with the fast development of infotech and network technology, various digitizings, intelligentized equipment arise at the historic moment, and the digitized epoch arrive.And field bus technique be exactly a kind of be transmission medium with a pair of twisted-pair feeder, be the technology of purpose with the transmission of digital signals.It has solved above-mentioned people's demand.The wiring of field bus system is very simple, owing to can articulate a plurality of equipment usually on a pair of twisted-pair feeder or a cable, thereby the consumption of cable, terminal, groove box, crane span structure significantly reduces, and the line design also significantly reduces with the workload of joint check and correction.When needs increase field control equipment, need not to set up new cable, can be connected nearby on original cable, both saved investment, also reduced the workload of design, installation.
