Abstract

The invention relates to a monitoring system and monitoring method for real-time exhaust of a diesel mine locomotive. The monitoring system comprises a tail gas collecting module, a diesel mine locomotive working condition collecting module and a data processing module. The tail gas collecting module is used for collecting the content of carbon monoxide and oxynitride in tail gas of the diesel mine locomotive in real-time through an explosion proof type gas sensor. The diesel mine locomotive working condition collecting module is used for collecting the rotation speed of an engine of a mining diesel engine and the position of an accelerator of the diesel mine locomotive. The data processing module is used for calculating exhaust data under different working conditions according to the rotation speed of the engine, the position of the accelerator and the content of the carbon monoxide and the oxynitride in the tail gas. According to the rotation speed of the engine, the position of the accelerator and the content of the carbon monoxide and the oxynitride in the tail gas, the exhaust data under different working conditions are worked out, in this way, the real-time exhaust of the diesel mine locomotive can be in one-to-one correspondence with the real-time working conditions, and exhaust indicators of the locomotive in practical application can be reflected accurately and objectively.

Description

technical field [0001] The invention relates to the technical field of mining diesel engine control, in particular to a real-time emission monitoring system and monitoring method for mining diesel locomotives. Background technique [0002] The power source of the mining diesel locomotive comes from an explosion-proof diesel engine, and exhaust gas will inevitably be generated during its operation. Generally speaking, the composition of engine exhaust gas is relatively complex. When the combustion is complete, the general tail gas components are carbon dioxide, water vapor, remaining oxygen, unburned nitrogen, etc. When the combustion is not complete, the exhaust gas will be doped with harmful gases such as carbon monoxide, nitrogen oxides, hydrocarbons, sulfur dioxide, particulate matter, and aldehydes. However, the working conditions of diesel engines after explosion-proof modification are even worse, the intake and exhaust pressures are increased, the cooling method adop...
