As shown in fig. 1 to 5, the system for monitoring low oxygen environment in an air-conditioned cabin of the present invention comprises:

and the oxygen detection end is used for monitoring an oxygen concentration signal in the modified atmosphere bin in real time. The oxygen concentration sensor can be an oxygen detector or an oxygen concentration sensor, and the oxygen detector or the oxygen concentration sensor is arranged in the modified atmosphere bin, so that the oxygen concentration signal in the modified atmosphere bin can be monitored in real time conveniently.

And the signal transceiving end is used for receiving the signal of the oxygen detection end and sending out a processing signal.

And the electronic gate control end is used for receiving the processing signal sent by the signal receiving and transmitting end and controlling the opening and closing of the electronic door lock through the power supply switch. Specifically, when the power supply switch is switched on, the electronic door lock is automatically locked; when the power supply switch is switched off, the electronic door lock is in a normally open state.

And the alarm end is used for receiving the processing signal sent by the signal receiving and transmitting end and triggering the alarm end to alarm. In particular to an audible and visual alarm or a voice alarm.

Specifically, when the oxygen concentration signal of the oxygen detection end received by the signal transceiving end is lower than 19.5%, the electronic door control end switches on the trigger power supply switch, and the electronic door lock is locked; and meanwhile, the alarm end triggers an alarm. The alarm is mainly used for warning that the controlled atmosphere bin is in a low-oxygen dangerous state, prompting custody staff to wear a breathing machine when entering the controlled atmosphere bin, and only authorized staff can enter the controlled atmosphere bin, so that the possibility that non-professional labor staff forget to enter the controlled atmosphere bin due to unknown danger is avoided, and a safety protection measure is provided for the staff who enter and exit the controlled atmosphere bin.
