| Abstract: | The oxygen technology by adopting PSA molecule is presented and the control process of the high-- power oxygen machine is researched. The microcomputer control system for the high-- power oxygen machine is designed based on microcomputer AT89C52. The system combines many chips such as TCN75 and A/D, etc to gather and convert the temperature signal, pressure signal, flux signal and purity signal. The system utilizes photoelectrical coupler to control and drive every magnet valve and also communicates with upper computer by RS485. The software and hardware of system is expounded detailedly. The practical implementation shows that the control system for the oxygen machine has reliable capability and is easily operated. It also shows that the performance is high and realizes the intelligentized and digital control really. |
