The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.
As shown in Figure 1, DC/DC power isolation module 1 provides isolated from power for each sensor, thereby reduces to disturb; The PLC primary controller is controlled two oxygen supply valves through control relay 2 and relay 5; Connection terminal 3 its wiring and the protective effects of band wire fuse; Sensor 4 comprises pressure, temperature, humidity, gas concentration lwevel, oxygen concentration sensor; The 24VDC power module provides direct supply for each sensor and industrial flat-panel monitor and PLC primary controller; The PLC primary controller is the brain of The whole control system; The current signal of the corresponding 4-20mA of oxygen concentration sensor concentration value, analogue collection module is responsible for gathering current signal, and is translated into digital quantity.
As shown in Figure 2, oxygen concentration upper limit alarm indicator lamp 9, when greater than 23% the time, indicator lamp is bright; Industry flat-panel monitor 10, it can show oxygen concentration, gas concentration lwevel, temperature, humidity and cabin internal pressure; Oxygen concentration lower limit warning indicator lamp 11, when less than 17% the time, indicator lamp is bright; Oxygen concentration sensor is selected change-over switch 12, and select switch 12 carries out the selection of two or more oxygen concentration sensors, selects wherein control of carrying out the oxygen supply valve group.
As shown in Figure 3, oxygen concentration sensor changes into the current signal of corresponding 4-20mA with oxygen density value 0 ~ 25%, gets into analogue collection module; Analogue collection module changes into corresponding digital quantity with analog quantity, and digital quantity gets into the PLC primary controller, and CPU controls two relays through control corresponding digital amount; Two relays are controlled the switching of two-way oxygen supply valve respectively, thereby realize the control to oxygen flow, and concrete mode is: two-way oxygen supply valve one Lu Changkai; One the tunnel is normally closed, during normal oxygen supply, often opens oxygen supply valve and be in open mode; Normally closed oxygen supply valve is in closed condition, and when the PLC primary controller detected oxygen concentration and is lower than 19%, normally closed oxygen supply valve was opened; Often open oxygen supply valve and maintain the original state, oxygen flow increases and is twice like this, thereby oxygen concentration is raise; When oxygen concentration was elevated to 20%, normally closed oxygen supply valve recovered closed condition, and oxygen flow is got back to original value; When oxygen concentration is higher than 21%, often to open oxygen supply valve and close, normally closed oxygen supply valve maintains the original state, and is that oxygen flow reduces one times; When oxygen concentration is reduced to 20%, often open oxygen supply valve and restore to the original state, get back to normal oxygen supply state; When oxygen concentration is lower than 17% or greater than 23% the time, control corresponding delivery port through comparator, make corresponding warning indicator lamp bright.In addition, oxygen concentration sensor, gas concentration lwevel sensor, temperature sensor, humidity sensor and the detected analog value of pressure sensor all can show through the industrial flat-panel monitor that is attached thereto.The entire controller volume is less than 290 * 290 * 150 (mm), and weight is less than 5kg.
As shown in Figure 4; The software control flow process is: initialization I/O at first, carry out the timer sampling then, and oxygen concentration bound alarming value compares through comparator and controls corresponding delivery port; The digital quantity control of oxygen concentration adopts the rest-set flip-flop function to realize; Thereby realize control, finally control the oxygen supply valve group, reach the purpose of control oxygen concentration relay.
More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under situation about conceiving basically without prejudice to the utility model, the utility model can be done any type of modification.
