First and foremost, many mining equipment, whether underground or on an open cast mine does not have the capability push relevant machine data to the cloud. The advantage of push you data to the cloud is Life data of equipment no matter where you are. Preventative maintenance. Is your machine being used as effective as possible. In many cases, machines are capable to send their data to a SCADA system located in a control room and perhaps sends data to the cloud but utilizing a generic dashboard. We have the capability to change any aspect of a dashboard to give client a more comprehensive dashboard with richer data sets being displayed. Dashboards can also be catered to the clients liking removing unnecessary information and only showing what they need.

Scene 17

The name Raptor CAN Mine has its heritage in that we use a Dell gateway together with a in – house developed CAN Mine board that plugs into the Dell gateway.

Why we did this? Simple. Mining equipment doesn’t always have the intelligence to push its data to the cloud. We place the intelligence factor of a machine in two categories.  Legacy (Hydraulics/Pneumatics, usually no HMI) CAN bus system which in most cases has an HMI from which we intercept the data before it goes to HMI and then push it to the cloud.

Detailed explanation on Raptor CAN mine unit

Perception is that the Raptor CAN Mine in itself is a difficult concept to understand. It is not. As we’ve seen in the intro it is actually very easy to comprehend if you understand the unit’s main components. Component breakdown: Dell gateway CAN Mine board  Power harness that supplies Dell with 24 V from input VCC. The enclosure into which everything is fitted. Dependent on your communication preference the RCM can utilize either Ethernet or  WiFi  connection for breakout to To the cloud

Below slides will have pictures of the RCM assembly to give you an in depth understanding on how inside components  communicate and to pretty much make sense of the device at a lower level.

Let take a look at CAN bus. We all know it is a communication bus used mainly but not solely on vehicles. Keeping above in mind, it would be an obvious choice for mining equipment as it is an established protocol and very stable. Main rules of CAN bus: There are 2 important lines – CAN Low and CAN Low. There are numerous ways to determine which is which but voltage measurements are common and straight forward. CAN high fluctuated between 2.5V and 3.5V measuring between wire and common ground. CAN low fluctuates between 2.5V and 1.5V measuring between wire and common ground. Main rules of Legacy machines All functions of machine will start as an analog value which then triggers a relay on the machine. These machines are mostly pneumatic or hydraulically controlled As per machine electrical diagram, decide on points you want to connect to. Your input into the RCM unit will be Boolean.

Scene 24

As per above pin – out, installation of CAN Bus, is fairly straightforward. Establish where your CAN – High and CAN Low lines are Establish a common ground – you should have this by know as you searched for CAN lines using this point. Utilizing the 5 – pin connector, connect relevant pins to CAN lines, VCC and GND.

Scene 25

Connection done to Vehicle via M12 – 12pin  connector

The tricky part in installing a legacy vehicle is that the vehicle wiring needs to be up to date as from this wiring diagram we can determine to which points we have to connect to see e.g. percussion, transmission and alarms to name but a few. Below shows an example of where connection area sits (Normally in the electrical panel of the vehicle)

Scene 26

Both the above mentioned sensors are extremely easy to install on a hardware level. They make use of MODBUS RS485. In the respective manuals a set of holding and input registers can be found. These registers are then added as scan tags under Raptor Edge gateway portal, under the MODBUS driver. I will provide you with a live example now on what this will look like. There can be up to 32 sensors on one RS485 bus. The Dell has two I/O ports which means a total of 64 sensors can connected to one Raptor. Dell RS485 I/O input config shown below:
