Another project

In fact, this is a project I want to do, but it is difficult for me to realize, so I put it in the second place for the time being. I hope that with the deepening of learning, I have the ability and courage to realize it, because I think this will be more practical.

Respirator is the life support line of firefighters at the front-line disaster relief site. Daily operation and maintenance mainly depends on equipment personnel to ensure sufficient gas volume of oxygen cylinder. At the scene of the fire, the oxygen consumption of different team members is greatly different due to environmental factors, physical factors and other reasons. At present, the main way of traditional oxygen margin early warning is manual registration and timing by safety officers before entering the site, which can not effectively ensure the efficiency of disaster relief, but also has certain potential safety hazards. Safety accidents caused by team members ignoring oxygen margin have occurred at many fire sites.

Function descriptionVime

Firefighters are labeled with NFC tags, and respirators are equipped with NFC communication devices. Every time a team member enters the fire scene, the safety officer quickly reads the exclusive information of respirators and firefighters in the form of card reading through NFC near-field communication, automatically registers it to the equipment end and starts automatic timing. At the same time, the initial value of gas cylinder pressure can be directly read through NFC near-field communication. Firefighters estimate the remaining service time of respirators after entering the fire site, and display it on the breathing mask to remind team members to pay attention to the remaining operation time. The advantage of this project is that it is bound quickly, not affected by ambient light, weather conditions, QR code stains, etc. the PC screen is large, more information can be displayed at the same time, and there is a large space for later upgrading.

I designed the model of the terminal suitcase and made the interface of the terminal software (using PS). Now I’m learning how to realize the communication function
