Technical field
The utility model relates to oxygen generating plant control field, more particularly, relates to a kind of plateau and Controlling System of six tower oxygenerators efficiently of being applicable to.
Background technology
Medical oxygen generator adopts molecular sieve transformation absorption (PSA) oxygenerating technology and two tower structure making oxygens substantially, PLC---the control forms of magnetic valve group is adopted in its flow process control, therefore required magnetic valve is no more than 10, and pilot circuit is comparatively simple, but the oxygen yield is generally 25%～35%.Some product can be realized operational process automatization and remote monitoring function.
The control of slave unit and the control of making oxygen can be divided into following several: PLC control mode, full pneumatic control mode, micro-chip control mode, with EPROM as the control mode of programmable logic controller etc.
The PLC control mode generally is used for the control of large-scale medical oxygen generator, and this control mode has the advantage that control is flexible, simple in structure, reliability is high, and can realize the operational process automatization and the remote monitoring of total system.
Consider the product cost problem, in portable home-use oxygenerator, several modes in back that adopt more.Full air control unit is made up of two double air controlled two-position five-way valves, a unidirectional cylinder, a mechanical two-port valve, does not adopt electronic devices and components, and all are controlled automatically and are realized by pneumatic element.The advantage of this control mode be simple in structure, cost is low, shortcoming is that control is dumb, regulates making oxygen time parameter inconvenience, can not realize functions such as the full automatic control of equipment and remote monitoring.
The micro-chip control mode is to adopt micro-chip as time controller, realize the control of making oxygen by solid state relay control magnetic valve group, the advantage of this control mode is to utilize lower cost can realize stronger controlled function, but pilot circuit is especially imported, output interface circuit is complicated, be used in the large-scale medical oxygen generator, because a little less than the influence of support equipments such as air compressor machine, oxygen compressor, force (forcing) pump, immunity from interference, reliability is lower.
To sum up analyze, lack the Controlling System that cost is low, control flexibly and be applicable to hospital's concentrated oxygen supply oxygen generating plant in the prior art.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides that a kind of cost is low, the control Controlling System of six tower oxygenerators flexibly.
The Controlling System of the utility model six tower oxygenerators is achieved by following technical proposals, the PLC controller respectively with running status detector, six tower system oxygen main frames, go out oxygen valve, water drain valve, warning howler, liquid crystal touch screen and be connected; Described six tower system oxygen main frames are connected with the running status detector; Oxygen concn transmitter, intake pressure transmitter, adsorptive pressure transmitter, go out the oxygen pressure unit and be connected with the PLC controller respectively by A/D converter; Described PLC controller is connected with freeze drier, air compressor, pressure exerting device by rly. respectively.
Liquid crystal touch screen described in the utility model is connected with the PLC controller by the serial communication line.
The utility model is applied to medical oxygen generator, make it have functions such as operational process control automatically, remote monitoring, fault self-diagnosis and self-checkign n., online adjustment flow process parameter, thereby improve the end-use performance of oxygen generating plant effectively, for society provides convenience, safe, reliable and economic medical oxygen generator, solve the problem that civilian hospital is produced medical oxygen on the spot fast.

E) judge whether to exist fault, can repair, then carry out alert program, shutdown programm if can not repair if having fault then judge whether; The if there is no fault judgement of then whether shutting down;
F) fault can be repaired the fault selfreparing program of carrying out, and judgements of whether shutting down then is if select shutdown then carry out shutdown programm, if selection is not shut down then carried out oxygen container observed pressure P
O〉=oxygen container upper limit setting pressure P
OhJudge;
G) if oxygen container observed pressure P
O〉=oxygen container upper limit setting pressure P
OhBe false then executing state and failure testing and display routine; If P
O〉=oxygen container upper limit setting pressure P
OhSet up the standby program of then carrying out;
Carry out oxygen container observed pressure P then
O≤ oxygen container lower limit set pressure P
OlJudge, if oxygen container observed pressure P
O≤ oxygen container lower limit set pressure P
OlSet up and then carry out boot program; If oxygen container observed pressure P
