Description
Technical field
The present invention relates to a kind of gas automatic control system and method, particularly a kind of for oxygen automatic control system in survival capsule and method.
Background technology
Existing gas regulation technology occasion regulates as the gas regulation such as silo, vegetable and fruit booth belong to switch substantially, i.e. output is controlled and only opened and close two kinds of modes or chemical oxygen supply, needs manual control and can not accurately control.And human body belongs to complex organization, simple switch regulates and original chemical oxygen supply can not meet the harsh requirement of human body to living environment.
Application for a patent for invention provides a kind of Intelligentized air conditioning device No. 201110339596.4, principle of work be in the time that in confined space, oxygen concentration is low, gas concentration lwevel is while being greater than 1.0% or when each gas parameter exceeds standard, self-actuated controller sends signal, activate oxygen making reaction case, make it to promote oxygen concentration, purify air.Although but this kind of method has certain automaticity, control method has certain property delayed, can not regulate oxygen, accurately oxygen supply and dynamic time limit of oxygen to estimate function by real-time online, discomfort is used as rescue chamber oxygen control program.
Summary of the invention
The object of the invention is in order to overcome deficiency of the prior art, provide a kind of for oxygen automatic control system and method in survival capsule, solve existing Oxygen control method and there is certain property delayed, can not regulate oxygen, accurately oxygen supply and dynamic time limit of oxygen to estimate function by real-time online, discomfort be used as rescue chamber oxygen control program.
The technical solution adopted in the present invention is: in survival capsule, oxygen is automatically controlled and comprised system and method, and described automatic control system comprises: host computer, oxygen sensor, compressed air source unit, gas bus-bar, air pressure reducer, gas flow rate are measured feedback assembly, master controller and oxygen output solenoid valve; Compressed air source unit is measured feedback assembly by gas bus-bar and air pressure reducer and gas flow rate and is linked in sequence, and the gas delivery port that gas flow rate is measured feedback assembly is connected with oxygen output solenoid valve; Together with the gas flow rate measurement signal output part of feedback assembly and the output terminal of oxygen sensor, be connected with the input end of master controller, master controller is connected with host computer, the control output end of master controller is connected with oxygen output solenoid valve, the folding size of STOCHASTIC CONTROL oxygen output solenoid valve.
Described autocontrol method: be first high-pressure oxygen cylinder output after slow pressure is processed by compressed air source unit, enter same pilot piping through bus-bar, through air pressure reducer, effect becomes voltage stabilizing gas to be exported, after gas flow rate is measured feedback assembly measurement, through oxygen output solenoid valve, order output is carried out in control again;
In the time starting survival capsule, lambda sensor Real-Time Monitoring indoor environment oxygen concentration, and concentration corresponding signal parameter is passed to rescue chamber oxygen system master device processed, master controller carries out corresponding real-time regulating and controlling output according to oxygen actual concentrations and default variation feedback difference by oxygen output solenoid valve by embedded Fuzzy PID, and then oxygen concentration in accurate control cabinet, make trapped personnel in security context, whole control system realizes unmanned robotization;
Gas flow rate is measured feedback assembly Real-Time Monitoring oxygen expenditure speed and accumulative total consumed flow, deposits oxygen total amount and deducts accumulation consumed flow and be residual flow; On the basis of residual flow, system can predict that according to the current spending rate of oxygen remaining oxygen can realize oxygen pot life dynamic pre-estimating function service time.
Beneficial effect, owing to having adopted such scheme, compressed air source unit storage adopts setting up of bomb storage mode and atmospheric buffer device can evade the difficult problem with wayward reaction velocity under chemical oxygen supply mode in seal cavity.Choosing of gas flow rate flow measurement device makes Oxygen control form backfeed loop.Thereby system utilizes the stepless time adjustment of the inner direct current generator of oxygen output valve to realize the continuous uniform oxygen supply of oxygen.Fuzzy PID is applied to system master device processed inside to adapt to the time variation of oxygen control system simultaneously.The continuously accurate oxygen supply that it is survival capsule built-in system that oxygen output valve relies on the electrodeless variable-speed characteristic of direct current generator provides basis.The fuzzy PID algorithm that system controller is embedded in can be realized the self-adaptation of the time-varying characteristics to system model, thereby reaches accurate oxygen supply.Gas flow rate flow measurement device choose the realization that can estimate function the dynamic time limit of completion system oxygen.The design of system controller reduces and controls power consumption when adopting FPGA can solve coal mine intrinsic safety and require as control chip.
