Abstract

The invention discloses a mining survival time calculator which comprises a motherboard, a display screen, control display modules and a power supply. The mother board comprises a circuit board, an arithmetic device, a controller and a memorizer, the arithmetic device, the controller and the memorizer are integrally mounted on the circuit board, the display screen is electrically connected with the corresponding control display module, the control display modules are electrically connected with the motherboard, the motherboard is electrically connected with a keyboard, and the motherboard and the display screen are respectively and electrically connected with the power supply. Survival time of a person sealed in a closed space can be rapidly calculated when a mine disaster happens, so that emergency rescue and disaster relief are reasonably arranged, the safety coefficient of mining personnel is improved, and loss caused by the mine disaster is reduced.

Description

technical field [0001] The invention relates to equipment related to mine safety rescue, in particular to a mine survival time calculator. Background technique [0002] When an underground coal mine disaster occurs, the air quality of the shelter determines the longest time that the people in distress can survive in the space. Generally speaking, if there is no or very little harmful gas in the shelter, often only press O 2 reduced to 12% and CO 2 The time required to increase to 10% (whichever is the lesser of the two) estimates the maximum time a person can survive. There is no survival time calculator in the market for mine rescue and disaster relief. Therefore, it is necessary to design a mining survival time calculator, which can be used to quickly calculate the survival time of people trapped in a closed space when a coal mine disaster occurs, so as to reasonably arrange emergency rescue and disaster relief. Contents of the invention [0003] The invention fills ...
