Specification

Description:FIELD OF THE INVENTION
This invention relates to an iot integrated hydraulic oil condition monitoring solution for hydraulic excavator
BACKGROUND OF THE INVENTION
This development offers an improved technique for IoT integration and cloud-based technology-based hydraulic oil condition monitoring in hydraulic excavators. The hydraulic system continuously collects critical data, such as temperature, flow rate, acidity, and pollution levels, by installing a network of sensors within it. An integrated system like this increases the lifespan and dependability of equipment and improves operational efficiency by allowing remote monitoring and timely response based on the state of the oil.
The issue of effectively and proactively monitoring the hydraulic oil condition in hydraulic excavators is tackled by this innovation. Manual inspections and planned servicing are the mainstays of conventional maintenance techniques, both of which can be time-consuming, costly, and error-prone. Hydraulic systems are susceptible to early wear, reduced performance, and unplanned breakdowns that need costly repairs and downtime if problems are not identified in a timely manner.

A flow-rate control valve 15 capable of selectively closing the reservoir line 8 c is arranged and, when a rod-side hydraulic pressure of the arm cylinder 2 has increased to a preset value or greater while grading work is performed by a combined operation of boom raising and arm crowding, the reservoir line 8 c is closed by the flow-rate control valve 15 to prevent drainage of rod-side pressure oil from the arm cylinder 2 to the working oil reservoir 8 c and to feed the rod-side pressure oil to a bottom side of the boom cylinder.

With the use of IoT technology, cloud-based analytics, and remote monitoring capabilities, this innovation offers a comprehensive method for keeping an eye on the hydraulic oil condition in excavators. The goal is to maximize maintenance efficiency, minimize downtime, and increase equipment lifespan. The implementation of a network of sensors and microcontrollers placed strategically throughout the hydraulic system is the key component of this breakthrough. These sensors, which include the liquid temperature sensor, velocity sensor, and NAS sensor, are made to keep an eye on important factors like temperature, flow rate, acidity, and contamination levels that are crucial for determining the health of the oil. The Atmega2560 Board, which serves as the system's central control unit, then processes and analyzes the data that these sensors have acquired.
The board's preprogrammed algorithms assess the sensor data by contrasting it with predetermined thresholds and patterns that point to possible problems or a decline in oil quality. The processed data is then sent via communication modules such as the ESP01 WiFi board or GSM modem to a specific cloud server. The central location for organizing, maintaining, and evaluating the gathered data is this cloud server. Sophisticated algorithms on the cloud server further examine the incoming data to provide trend charts, vital alerts, and real-time information about the state of the hydraulic oil. Users can get these insights via an internet-based, personalized web-based dashboard. Operators and maintenance staff have the option to safely log into their dashboard accounts and view an intuitive interface with real-time hydraulic oil status updates, trend analysis charts, and important alarms. This gives them the ability to remotely check on the state of the oil and act quickly to address any anomalies or possible problems.
