A locomotive wind pressure and flow monitoring device and method

Abstract

The invention provides a locomotive wind pressure and flow monitoring device and method. The locomotive wind pressure and flow monitoring device is characterized by comprising a pressure sensor used for collecting real-time data of wind pressure of a main reservoir of a locomotive, flow sensors used for collecting real-time data of wind flow of a wind supply duct of the locomotive, a host which can preset alarm threshold values of the wind pressure of the main reservoir of the locomotive and the wind flow of the wind supply duct of the locomotive according to locomotive operation requirementsand alarms in signal connection with the host; the host is in data transmission connection with the pressure sensor and the flow sensors and receives and displays the real-time data. If the real-timedata of the wind pressure or the real-time data of wind flow are less than or equal to the corresponding alarm threshold values, the host controls the alarms to give alarm. The locomotive wind pressure and flow monitoring device and method can change the alarm threshold values of the wind flow of the wind supply duct and the wind pressure of the main reservoir of a locomotive according to change of locomotive operation parameters and road condition information, thereby improving the reliability and practicality of locomotive wind pressure and flow monitoring; the air output flow of a dryer ofa locomotive can be monitored in real time, so that safety hazards can be reduced and operation safety of a locomotive can be improved.

Description

technical field [0001] The invention relates to a locomotive wind pressure and flow monitoring device and method, which are used to realize real-time monitoring of the locomotive wind pressure and flow. Background technique [0002] If the electric locomotive lacks effective monitoring and management of the air supply pipe, the driver will not be able to know the real-time wind usage status of the vehicle. If the air consumption of the vehicle air supply pipe system increases and measures cannot be taken in time, the total air pressure may change too frequently and too fast, causing Driving poses a safety hazard. When the air compressor of the electric locomotive is working abnormally or the air volume of the vehicle is too large or the air leaks, the total air pressure of the locomotive main air cylinder will not be effectively supplemented, causing the total air pressure of the locomotive to drop too quickly. It is easy to find that the air compressor is working abnormall...

AI Technical Summary

Problems solved by technology

[0006] In the above schemes, the air flow of the air supply pipe of the locomotive and the air pressure of the total air cylinder are detected to judge the real-time wind usage status of the vehicle, and an alarm is issued when there is an abnormality, so as to achieve the monitoring of the real-time wind usage status of the locomotive. During the operation of the locomotive, as the operating parameters and road condition information change, the air flow of the locomotive air supply pipe and the demand range of the total air cylinder air pressure will also change. When the desiccant in the locomotive is severely damp or polluted , the output capacity of the dryer will be reduced, and in serious cases, it will cause insufficient air supply capacity of the main air cylinder, which will also cause low total air pressure. The method of monitoring the air pressure and flow of locomotives is changed according to the demand of air pressure, and there is no method of judging the air output flow of the locomotive dryer, and this kind of fault is also difficult to judge manually
