System and method for lube cost control on heavy machinery

Abstract

A system is provided for automatically reporting all the lubes delivered from the lube truck in the field and on the lube bay at the workshop in mining & related business. All the lubes dispensed from both sides need to be accounted for on each machine due to the high cost and volume. The system improves the actual lube process on mining environment avoiding human mistakes and creating a reliable lube report.

(40) The present invention provides a system for automatically reporting a detailed lube consumption on heavy machinery and related business. The system is based on a passive RFID tag/device installed on each machine lube port (11, 12,13,14,15, 16, 17) with the information of a machine number (TAG) and lube type used on each lube port.

(41) The process of the invention as indicated in FIG. 4 for the field and FIG. 6 for the workshop works with the installation of one passive RFID on each lube port of the heavy machinery. The passive RFID on the lube ports provides the information of Machine identifying number (TAG) and lube type. Each digital lube meter/dispensers (29, 31) have a RFID reader (30) inside. RFID reader from the digital lube meter/dispensers for each lubricant can only read and match with the right passive RFID allowing to deliver the right lubricant on the right lube port in order to avoid human mistakes and mixing lubricants.

(42) The digital lube meter/dispenser reports to the lube truck data logger in the field or to the lube bay data logger at the workshop the Machine identifying number, lube type, volume dispatched, date and time. This information is sent from the data logger to the server in order to create the corresponding report viewable in a spreadsheet or CSV file.

(43) The system of the present invention tracks the budget expenditures and equipment conditions so that when heavy machines have a high lube consumption the system is used to provide a warning for early detection of a failure. Accordingly, the actions to repair and correct any deviation from normal conditions will be faster when compared to the actual manual report system (FIG. 1 and FIG. 2). This is done by specific parameters to compare the actual lube consumption versus the normal expected consumption.

(44) Specifically, the process of the present invention begins in the same way for the lube truck and for the workshop. The digital lube meter/dispenser (29,30, 31) is selected to deliver one lubricant on the machine lube port and as the digital lube dispenser is proximate to the lube port for serving the lube, the inner RFID reader (30) gets permission from the passive RFID installed on the lube port (11,12,13,14,15,16, 17) to release the lube. By using this ID matching, the system guarantees that the right lubricants are served on the right lube port. Once the lubricant is filled, the digital lube meter/dispenser is returned to its storage position and the information about the volume delivered is sent to the data logger. The data contains the equipment identifying number (TAG), lube type, volume, date & time. After that, the data is sent from the data logger to the server to create the report. FIG. 7 indicates the source from where the data for the lube report is collected. The reports can be accessed from the server for all the authorized users, where FIG. 8 illustrates an example of a report according to an embodiment of the invention.

(45) The information stored in data logger on the lube truck is transferred wirelessly to the server when the lube truck comes to the lube bay area to refill the lubes, preferably via a WIFI network. The use of RFID on the lube ports of the equipment linked with the RFID reader (30) guaranties the creation of an electronic report free of human mistakes.

(46) Although the present invention has been described herein with reference to the foregoing exemplary embodiment, this embodiment does not serve to limit the scope of the present invention. Accordingly, those skilled in the art to which the present invention pertains will appreciate that various modifications are possible, without departing from the technical spirit of the present invention.
