ONLINE MONITORING SYSTEM AND METHOD FOR HYDRAULIC OIL OF POWER AERIAL WORK VEHICLE, AND DEVICE

An online monitoring system and method for hydraulic oil of a power aerial work vehicle, and a device. A microprocessor receives a monitoring instruction, and the microprocessor sends an oil extraction signal to a gear pump; then, the gear pump is started after responding to the oil extraction signal, extracts hydraulic oil from a hydraulic oil tank, and conveys same to the hydraulic oil tank by means of a pipeline, wherein the hydraulic oil in the hydraulic oil tank is cyclically extracted; a detection module detects the hydraulic oil in the pipeline in real time, generates oil quality parameters and sends the oil quality parameters to the microprocessor; and the microprocessor compares the received oil quality parameters with preset parameter threshold values, and finally generates oil quality state information and displays same. By means of a microprocessor, a gear pump and a detection module, online monitoring can be performed on the oil quality state of hydraulic oil in real time, oil quality state infor
