There are many countries where there is no snow to ski on, or simply because there are no mountains. Winter sport enthusiasts who want to gain some experience before going to the slopes in the mountains can do this at a local indoor ski center.

Learn how to ski or snowboard step by step

SkiMachine from the Netherlands, supplier of indoor ski slopes, delivers machines which can be adjusted to the desired height with a conveyor belt covered with so-called ski grass. The conveyor belt is positioned at an angle and moves upwards to the top of the slope; this simulates the sliding speed on the slopes. A sprayer installation keeps the slope moist to give an optimum sliding experience.

Depending on the pupil skier’s competency, a practice bar can be mounted, and they can see themselves moving through a big two-way mirror. The indoor ski slopes are used to give skiing and snowboarding lessons.

Safety first

When a pupil touches a drawstring, the conveyor stops immediately. This prevents him or her from being pushed against the wall after a fall. A drawstring is fastened at the top and on both sides of the slope. In addition, there is a sensor on the top side of the slope that immediately stops the conveyor as soon as this type of movement is detected. The remote control provided by Tyro can manage the speed and also function as an extra stop.

The Pyxis Auriga for operating a ski slope

The teacher has complete control with the Pyxis wireless control which has four function keys. In addition to increasing and reducing the speed, the machine can also be switched on or off, as is normally done. If a student loses balance, he or she can immediately press the quick stop button; the remote control and the receiver have a reaction time of less than 0.1 of a second. The Auriga receiver is connected to the control box.

A Tyro remote control is also delivered as a standard part of the ski slopes. Besides your own icons the remote control is also provided with your logo.

The DS range of speed and standstill monitors are all SIL3/PLe and SIL2/PLd certified.

The abbreviation SIL (Safety Integrity Level) comes from the field of functional safety and is used in the international standard IEC 61508. The specific standard of safety-relevant electrical control systems is defined in the IEC or EN 62061.

The reliability of safety functions of electrical systems is classified into four different safety integrity levels. These classifications are SIL1 to SIL4. SIL1 is the lowest reliability classification, and SIL4 is the highest. The DS range of safety speed monitors can achieve a SIL3 safety integrity level.

PL (Performance Level) is used similarly to the safety integrity level when classifying safety classes. The performance level falls under the standard ISO 13849. This classification takes place from PLa to PLe. PLa has the lowest risk reduction, and PLe has the highest. The DS range of safety relays is certified up to PLe.

The picture below depicts the risk analysis, which assists in the calculation of the performance level. The first analysis step, S determines the severity of the injuries that can be sustained due to an accident. The analysis F deals with the frequency of a possible accident or the duration of the user’s stay under the risk. There is also a section regarding the possibility of avoiding the threat and the limitation of the damage that might occur. Consequently, high-risk applications require components with the highest performance level PLe, such as the DS Range of speed monitors.

The table in the picture compares the performance level to the corresponding safety integrity level. As a result, the combinations SIL3/PLe and SIL2/PLd can be derived.

What is sil3/PLe and SIL2/PLd

A trend that we as exhibitors saw at the last ‘Agritechnica’ trade fair in Hanover is the rediscovery of wood for heating and generating electricity. Wood is gaining a lot of popularity as a renewable energy source and its financial advantages.

Log-splitter

Special forestry machines are used for both the preservation and processing of wood. An example of such a machine is a log splitter, which helps cut the tree trunks into small pieces.

Forestry machines are remotely controlled

Splitters are hydraulically driven. They split logs in a vertical or horizontal position. A thick tree trunk is very heavy, and therefore, to simplify the transportation of those thick trunks to the splitter, a compact winch is mounted on the machine.

Fornax Safe remote control

The manufacturer of log splitters uses the Tyro Fornax Basic / Aquarius remote control for this application.

Radio remote attached to a belt

When dragging the tree trunks, it is essential to position them correctly on the splitter. Using a belt-clip, the operator can attach the remote to his belt. This makes it easier for him to use the remote control when required to adjust the position of the tree trunk. He can now operate the winch to pull the tree trunk and position it as desired without going back and forth to the splitting machine. Thus, having a Tyro remote is a definite plus in terms of comfort and convenience, with a positive effect on productivity.

wireless remote control for irregation

A sprinkler system generally consists of a powerful pump – for example, the pump that pumps out the water from a ditch. When the computer indicates that the spray gun has finished with its program, the pump is expected to stop immediately.

This is done with the help of an Aquarius transmitter and an Aquarius receiver.

Aquarius M2M system

The Aquarius is programmed as a transmitter that receives a signal from the spray gun and sends it to the pump (at a distance of 700 meters!) which then directly shuts down. All this without human intervention, without the touch of a button.

This solution comes from the demand for a stable communication signal that the user can always trust. Tyro Remotes offers this guarantee with the M2M control systems based on the latest radiographic technology.

Machine-to-machine

The term ‘M2M’ or ‘Machine to Machine’ stands for the communication between machines without any human intervention.
