Remote Monitoring of Tyre Pressure

Outline

Data Capture Services Australia supplies a Data Capture Device (DCD) that measures tyre pressure and temperature in real time and transmits each change of pressure or temperature to the Data Capture Server (DCS).

The Server monitors the pressure and temperature of each tyre and based on an algorithm determines if a tyre has an abnormal reading. When an abnormal reading is detected the DSC generates a workflow identifying the equipment and tyre position to be corrected. The algorithm takes into account the current temperature of the tyre and includes variables based on the tyre manufactures requirements, the type of equipment and the tyre position.

The following alarms are actioned immediately:

    • Low pressure warning
    • High pressure warning
    • High temperature warning
    • Rapid deflation

 

Tyre Sensor Cap

The DCD for Tyre Pressure comprises

    •  4 or 6 Earth Mover Sensor Cap (EMSC). One fitted to each tyre on the equipment
    • 1 EMSC Receiver
    • I DCD
 The standard valve cap is replaced with an EMSC that incorporates a pressure and temperature sensor enclosed within a protective aluminium case. The EMSC screws onto the EM valve stem, replacing the traditional EM cap. The EMSC is designed to withstand the rigors of a harsh mine environment and has a minimum one year life. When the battery is depleted the EMSC is replaced.

 

Data Capture Server – Tyre Pressure Module

The EMSC transmits the current tyre pressure and temperature to the DCD. The DCD forwards a record to the Server each time there is a change in either pressure or temperature.

The Tyre Pressure Module on the Server records the pressure and temperature of each tyre. A set of variables are maintained based on the manufactures recommended pressure setting for a given temperature. In addition, the DCS allows different standards to be configured depending on the tyre position. For example, the standard pressure of the front tyres of an FEL can be set to a different value to the rear.

Data is recorded on a Microsoft SQL database and this data is accessible at any time is available for download by the customer.

The Business Intelligence reporting system provides historical analysis and uses pre-configured reports written in Excel and PowerPivot.

At any time a report on the entire fleet detailing all the pressure adjustment required by each tyre is available. This report allows for increased utilisation of the fleet as the current practice of reducing pressure by resting equipment can be measured. The system also advises the required increase or decrease in pressure for each tyre to bring all tyres back to the standard pressure for their current temperature.
