The invention discloses an oxygen cabin controlled by a computer. The oxygen cabin comprises a touch screen industrial control integrated machine, a PLC, a cabin body, a humidification antistatic device for inflating the cabin body with humidity, an oxygen adding device for inflating oxygen into the cabin body, an oxygen exhausting device for exhausting oxygen inside the cabin body out of the cabin body, a temperature adjusting device for adjusting the temperature inside the cabin body and a monitoring device for detecting the state inside the cabin body. The dehumidification antistatic device, the oxygen adding device, the oxygen exhausting device, the temperature adjusting device and the monitoring device are electrically connected with the PLC. The PLC is connected with the touch screen industrial control integrated machine through an RS 485 communication circuit. The oxygen cabin has the advantages that the varieties of monitored parameters are complete, the automatic control degree is high, the control process is stable and accurate, parameter fluctuations are small, it is ensured that the pressure, temperature, humidity and the oxygen concentration of the oxygen cabin are still within the set range, and the using effect and using safety of a patient are ensured.
