Enhancing Safety for Miners on Coal Stockpiles

bwi eagle lightning detection systemThe most significant concern on a coal storage pile is the risk of a dozer falling into the feeder cavity. This occurs when unseen pockets develop in the pile and collapse, swallowing the dozer. The operator’s safety and protection depend on how fast the feeder can be stopped and emergency personnel alerted.  

At that critical moment, the dozer operators must rely on their ability to summon help quickly and reliably. The handheld CB radio in the dozer may not be enough if the signal cannot get through the coal pile. Wireless stop switches are now used to ensure continuous communication so emergency alerts can be sent and received immediately.   

Fail-Safe Protection for Dozers on Coal Stockpiles

The BWI Eagle Dozer Stop Switch wireless system is purpose-built to enable dozer operators to stop the feeder and alert emergency personnel with a single button push from inside the cab.

The Dozer Stop Switch system redefines safety on coal storage piles by featuring a full duplex (handshake) link and an operating range of more than 4,500 feet.

If a dozer starts to fall into a cavity, the operator pushes the button to stop the feeder and alert emergency personnel. It also automatically stops if the handshake link is broken due to a signal loss or power failure, ensuring the feeder stops if the operator is unable to push the button.

The BWI Eagle Dozer Stop Switch is the only fail-safe protection for dozer operators working on coal stockpiles with underground feeders. The system features a continuous link between the dozer operation and the control PLC. Falling into a cavity would break the RF link and activate the e-stop as if the button had been hit.

Other RF systems rely on the emergency signal reaching the control receiver, but fail to consider that RF transmissions will not penetrate through layers of coal.

The system can monitor up to eight dozers simultaneously with a precise frequency auto-scanning signal that cannot be blocked or jammed. Integral high-current relays allow direct interfacing with other equipment and devices, while 900MHz spread-spectrum technology ensures the utmost security and reliability. When the operator logs in, onboard LEDs at both ends of the link verify that the handshake has been established, giving the operator and all other involved personnel a sense of confidence and trust.

Importance of Reliable Communication

Reliable communication between the controller and the generator is crucial for generators to function effectively, especially those that are mechanically or electronically governed. Any lapse in communication can lead to downtime, reducing productivity and increasing costs. Ensuring seamless interaction between the control systems and the generators is paramount for maintaining a consistent power supply and operational efficiency.

Durability in Harsh Environments

Generators often operate in challenging environments, exposed to harsh weather conditions such as rain, snow, dust, and extreme temperatures. Controllers used to power these solutions must be exceptionally durable and designed to withstand these elements. Robust construction and advanced engineering ensure that these control systems can perform reliably, no matter the environmental conditions.

Efficient Controllers for OEMs

By integrating advanced controllers into mobile generators, Original Equipment Manufacturers (OEMs) can monitor and manage generator performance from virtually anywhere. This integration offers several significant benefits:

Better Management of Start/Stop Times: Control solutions enable precise management of when generators start and stop, optimizing their use and reducing unnecessary run times.

Fuel Consumption Adjustment: Efficiently managing fuel consumption is critical for cost savings. Advanced control systems can adjust fuel usage based on real-time data and operational needs.

Issue Diagnosis: Early detection and diagnosis of potential issues can prevent costly breakdowns. By adding telemetry devices with remote monitoring capabilities, controllers allow for real-time diagnostics, helping to identify and address problems before they escalate.

Reducing Downtime and Increasing Efficiency

One of the most significant advantages of integrating control solutions into mobile generators is the reduction of downtime. With real-time adjustments, these systems ensure that generators are always operating at their best. This reliability translates into less downtime for mobile equipment, enhancing overall job site productivity.

The ability to manage generators brings a new level of efficiency and reliability to job sites. OEMs can achieve significant cost savings and operational improvements by ensuring robust communication, durability in harsh environments, and comprehensive remote monitoring. These advancements enhance performance and provide a competitive edge in today’s demanding industrial landscape.

The research station for vegetable cultivation (PSKW) in Belgium is a test facility focused on research, development, and innovation in the agricultural sector. The organization has recently provided a Tyro wireless remote control on a New Holland tractor. In combination with a GPS system, one person is less required for leek cultivation. This is not only during harvesting but for all tasks at the testing facility.

The GPS with which a preset line is followed.

Leek cultivation with the assistance of a remote control.

The New Holland tractor is operated by a GPS in the tractor. This system steers the wheels of the tractor automatically. A preset line is followed, which is also followed when planting the leeks. By applying the necessary safety measures no one is required to sit in the tractor. The GPS system, combined with our wireless Pyxis remote control, allows the tractor to carry out all types of actions.

 

Operate a tractor with a remote control

Due to the 8 functions of the remote control, the driver can stop the tractor, drive it in reverse, and then drive forward. When the ground is wet the tractor must be driven slower and when on dry ground the driving speed can be increased. Next to that, the drives of the machine can be switched on or off, and with the assistance of the remote control the machine is lowered and then raised again.

Tyro remote controls are used in very tough applications.

 

Safety

By pressing the stop button on the top side of the controls everything switches off immediately. The tractor is provided with an obstacle safety provision that stops the tractor if a part breaks down. As an extra safety measure, the range is set to +/- 30 meters; the system immediately cuts out as soon as there is no contact between the remote control and the receiver. 

List of functions

  • Forward drive, reverse drive
  • Start, stop
  • Speeding up, slowing down
  • Pto shaft in/out
  • Stop button: The motor of the tractor completely shut down
  • Out-of-range protection

Video of application

Below is a short video in which the remote control is used for harvesting leeks. Here you can see that the leek falls onto a conveyor belt. The leek is then taken from here and placed in a metal box. As soon as this is full a new box will be loaded and can be driven further.

The wireless control is not only used for harvesting but also when planting, sowing, and hoeing of the leek. In the meantime, the PSKW has also provided their other tractors with a Tyro remote control.
