Engine Monitoring & Control



RanchMaster is capable of remote monitoring and controlling engine-driven equipment such as irrigation and mining pumps, generators or wind machines or any other engine-driven equipment. The solutions range from simple on-off monitoring using an oil pressure transducer to complete monitoring of engine statistics and start/stop of engine.

The RanchMaseter RM210 or RS210 node unit is connected to the engine controller or transducers. This unit regularly samples key statistics and transmits back to the RanchMaster online software application. When the user decides to start or stop, or when indicated by a program defined online, the signal is transmitted back to the unit and then the engine is started or stopped as required, typically within seconds. The connectivity can be via the cellular/mobile phone system or by direct internet connection.

Simple remote engine monitoring (no control)

The most economical solution allows only monitoring; no remote control is provided. An RS210 CELL unit is placed near or on the engine and a pressure transducer is attached to the pressure line, typically using a T near an existing pressure gauge. The RS210-CELL will upload data to the online application every 30 minutes, providing detailed historic data on engine run time. This can be used to indirectly determine such measures as gallons/kilolitres of irrigation water delivered, verification of frost protection equipment function and even the amount of fuel consumed.

Advanced engine monitoring and control (via Murphy Controller)

This is the most advanced solution provided through both real-time monitoring and remote control. In this case, a Murhpy EMS-PRO controller is required. The Murphy controller is connected to an RM210 base station unit using a special cable providing both power and RS-485 network communications. Cellular/mobile coverage is required, or optionally a nearby direct iternet connection (e.g. WiFi). The RM210 will pull current engine data at regular intervals (typically 5 or 15 minutes) and deliver this to the online application via the cellular/mobile network. The user may turn the engine on/off at any time, using a few simple clicks on the online application. Control signals are then sent via cellular/mobile network to the RM210 and immediately after the RM210 will send the signal via the RS485 connection to the Murphy controller. Control delay depends on cellular/mobile network, but is typically less than 1 minute.

The remote control can be ad-hoc, meaning the user decides to turn on or off and clicks a button in the online application. However, the control can also be programmed as part of an irrigation schedule and there by happen in a pre-determined fashion without requiring the user to go online. Finally, control could also happen as result of a rule reacting to input from another sensor in a Ranch Systems installation, such as a temperature sensor indicating frost or a level sensor indicating high or low water level.
