Design and Implementation of a Wireless Data-acquisition System for the Oil and Water Temperature Measurement in Diesel Locomotive
For oil and water temperature measurement in Diesel locomotive is the most essential work for ac-curate warming-up operation for Diesel locomotive in winter,A rapid deployment wireless system for the oil and water temperature measurement in Diesel locomotive is designed and implemented,including a wireless monitoring terminal,3 low-power-wireless temperature acquisition and transmission modules and 3 NTC tem-perature sensors with high sensitivity.The temperature sensors are mounted on the pipe line surface with en-hanced thermal insulation case in order to guarantee thermal-equilibrium with oil and water in pipelines.Oil and water temperature are acquired with the low-power-wireless temperature acquisition and transmission mod-ule,which is composed of low power MCU,wireless module and A/D circuit,and transmitted to the monito-ring terminal.Data are recorded and displayed at the wireless monitoring terminal which is implemented with an industry-HMI and a wireless gate.The data-acquisition and transmission module powered with independent battery is designated to be mounted as closer as possible for suppressing the interference from signal line of sen-sors.Practical application shows that the system can be rapid deployed on the Diesel locomotive in less than 1 hour with reliability and accuracy met the requirement of dynamic measurement of oil and water temperature in Diesel locomotive.
