Diesel-powered Irrigation pump with Murphy EMS-PRO controller and Ranch Systems RM210 remote telemetry.
Ranch Systems products are ideal for remote monitoring and control of 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 most advanced control is enabled by the partnership between Ranch Systems and Murphy Corporation and Macquarrie Corporation in Australia, allowing any suitable Murphy-controlled engine to be monitoring and controlled on-line.
Ranch Systems RM210 or RS210 unit is connected to the engine controller or transducers. This unit regularly samples key statistics and transmits back to the Ranch Systems online 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 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.
On-line Application: Typical map view of current status. Clicking on a specific value brings up a "drill-down" time graph. Clicking within an outline ("zone") brings up a stacked time graph (as shown in screenshot below)
Murphy EMS-PRO controller with connection to Ranch Systems RM210 for telemetry/on-line control
There several scenarios depending on the sophistication of the engine and the monitoring/control required. Below are some typical configurations
This is the most economical solution but 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. Cellular/mobile coverage is required. 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.
This is the most advanced solution provided both real-time monitoring and remote control. In this case a Murhpy controller such as the EMS-PRO 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 Internet 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. Whenever the user decides to turn engine on/off this is a few simply clicks in 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.
On-line Application: Typical time graph of key parameters (user selectable)
The following is typical data available online (depends on register map of Murphy controller used)
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.
One or more of the following products are typical for engine control applications:
RS210-CELL telemetry node
RM210 telemetry base station
| Part Number | Description |
|---|---|
| RM210-G/C/H | Ranch Systems celluar telemetry base station (GSM/GRPS/CDMA/1XRTT/NextG/HSPA models available). The RM210 is used where Murphy Controller interface is required and where the most real-time response is desired. |
| CBL-RS-MURPHY | Ranch Systems communications cable for Murphy EMS-PRO Controllers (RS485) |
| RS210-CELL-G/C/H | Ranch Systems celluar telemetry node (GSM/GRPS/CDMA/1XRTT/NextG/HSPA models available). The lower cost RS210-CELL option is used where monitoring engines without Murphy controllers and where 15-30 minutes delay in data upload and 5-15 minute delay in control is acceptable. |
| PS-MS-200 | Pressure transducer for simple monitoring of engine on/off via oil pressure. Typically paired with RS210-CELL. |
