Description
technical field:
the utility model relates to a kind of air compressor Redundant Control automation safety installations.
background technique:
current air Compressor unit can not realize automatically controlling and auto-compensation, in use Frequent Troubles, affects using effect, can not ensure safety, there is potential safety hazard.
summary of the invention:
the purpose of this utility model is to provide a kind of air compressor Redundant Control automation safety installations.
above-mentioned object is realized by following technological scheme:
a kind of air compressor Redundant Control automation safety installations, its composition comprises: one group of air-compressor set, described air compressor is connected with knock out drum, between described air compressor and described knock out drum, digital instrument is housed, described digital instrument is electrically connected with ethernet module, described ethernet module and programmable logic controller (PLC) electrical connection, described programmable logic controller (PLC) is electrically connected with described air compressor, described programmable logic controller (PLC) possesses man-machine interface, described knock out drum is connected with pneumatic valve, described knock out drum is equipped with pressure transducer, between described knock out drum and described pneumatic valve, flow transducer is housed, described pressure transducer and described flow transducer are all electrically connected with described programmable logic controller (PLC), described pneumatic valve is connected with user's pipeline.
the beneficial effects of the utility model:
1. the utility model design can the Functional Design Redundant Control scheme of coding by what adopt PLC technology, and redundant system is made up of two independently S7-400 systems of overlapping; During beginning, A system is main, and B system is for subsequent use; When in A system, mistake appears in any one condition or nextport hardware component NextPort, misoperation etc., programmable controller diagnoses the signal that makes mistake, and PLC technology automatically switches in the middle of standby system B and performs, and at this moment B is exactly main system, and A is standby system.
the utility model air compressor controls to be divided into and controls on the spot and telecontrol two patterns, completed by long-range switching push button on the spot, the monitoring state such as temperature, pressure in each state of air compressor and pipeline is divided into two-way to divide being clipped to DCS system and programmable logic controller system.When selecting to control on the spot, programmable logic controller (PLC) carries out Logic judgment to the running state of air compressor and line pressure temperature, then is stopped by the startup of each air compressor of programming Control; When selecting telecontrol, then needing the diagnostic routine by programmable logic controller (PLC), completing the judgement gathering motor status, line pressure, temperature and meet process logic, then being sent the instruction starting and stop by dry contact to programmable logic controller (PLC).7 air compressors are had to be divided into three groups in this device, first group 4, second group 2, the 3rd group 1.Can set air compressor at first group is main frame, subsidiary engine 1, subsidiary engine 2, standby host, and second group can setting air compressor be main frame, subsidiary engine, and the 3rd group is the shared standby host of first group and second group.Air compressor setting upload pressure condition or meet technological process condition under start successively, main frame underpressure or because misoperation do not reach starting condition, start and start subsidiary engine successively, if first group or second group of air compressor all starts deficiency or misoperation causes not meeting technological requirement, then start the 3rd group of air compressor.If first group and second group does not meet, the 3rd group preferentially supplies first group of startup.In like manner setting halt condition be also like this.
the utility model adopts Siemens S7-400 programmable controller to be core, coordinate the various data acquisition parameters of production engineering, comprise the enforcement of the actuating mechanism controls techniques such as air compressor, water pump, motor in addition, device EPA module, maximum transmission speed completes the data transmission in link, in device, digital instrument is according to MODBUSTCP/IP Data Transport Protocol, carry out Logic judgment by ethernet module in the data transmission in instrument to programmable controller, after diagnostic data is errorless, then can start or can carry out next step flow process of program.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is circuit diagram of flow transducer of the present utility model.
accompanying drawing 3 is circuit diagram of pressure transducer of the present utility model.
accompanying drawing 4 is circuit diagram of ethernet module of the present utility model.
accompanying drawing 5 is schematic layout patterns of one group of air compressor of the present utility model.
embodiment:
embodiment 1:
