ABSTRACT
This design is the mine gas concentration detection system design. This system uses the
single chip microcomputer as the main control. The control system of single chip microcomputer
can be used in various industrial environments. Even in the strong interference environment, it
can run stably, so it has a profound significance for the research of single-chip microcomputer
control system.
The first chapter of the design mainly describes the current situation of the mine gas
concentration detection system design, through the use of the gas detection system used in the
current society survey, function introduction, as well as for the current gas detection view, gas
use process encountered problems. For the current gas detection system for the use of scenario
analysis. The second chapter mainly describes the design and implementation of the mine gas
concentration detection system, whether it can meet the current design requirements, according to
the design requirements to select the components, drive circuit selection. Draw a general design
framework. The third chapter mainly describes the hardware design of the mine gas concentration
detection system, including the minimum system of the single chip microcomputer; key module,
alarm module, LCD1602 display module, buzzer module, ADC acquisition module, LED display
module circuit principle explanation and analysis, and finally summarizes the whole circuit. The
fourth chapter mainly describes the software design of the mine gas concentration detection
system design, the programming software keil has carried on the detailed introduction, compiles
the single module program flow, through the flow chart to compile the program, the key module,
the alarm module, the LCD1602 display module, the buzzer module, the ADC acquisition module,
the LED display module program. The fifth chapter mainly describes the simulation realization of
mine gas concentration detection system design, through Proteus Software to simulate the system,
and verify whether the designed functions meet the requirements.
At the end of the paper, the whole system is tested and recorded in detail, through which the
function of each module is verified and recorded, and then the system is analyzed to see if there is
