Description

[Detailed description of the invention] Remote control device for water ski tugboat Technical field The present invention relates to the broad field of water activities. More particularly, the invention provides water skiing This invention relates to a remote control device for controlling a ship that is towed. In particular, the present invention A remote control system using one or more Hall effect sensors to enable control of the ship. The present invention relates to a distance control device.

Background technology Water skiing traditionally involves a minimum of three people. One person who is a skier is driving attached by a tow lobe to a motorboat controlled by a second person Hold the I\$. The third person, the observer, watches over the skier. and verbally relays the skier's signals and the safety of the skier's situation to the driver. .

Skiers should be able to practice their skills independently while being towed. At the request of the person, we will tow the person and provide an observer to ensure the person's safety. We understand and rely on the efficiency and integrity of the bar and its drivers. So Additionally, skiers are responsive and willing to interact with drivers and observers. Without your participation, you will not be able to indulge in this water activity at all. Moreover, Even when the skier responds to noise and observers, the Due to the fact that we cannot physically control the performance of limited. The skier's ability to communicate with those on the boat is limited.

The area of cable skiing was developed as an alternative to the traditional form of water skiing. It's been coming. In these areas skiers do not have access to mechanical equipment on land. It is towed by an attached cable. However, these cable skis The equipment is installed on cable skis where these equipments are installed with huge capital support. are limited to parks and require some type of waterway condition in any case.

It can be adapted to the traditional form of water skiing on any waterway, yet is easy for drivers and drivers. It would be desirable to have a system that does not require both observers and observers.

111+ Such a remote control device that controls a boat capable of towing a water skier One attempt has been made in the prior art to replace this. However, this device There are big disadvantages. For example, always apply both hands to operate this device. It is necessary to have a considerable amount of physical strength to steer the tugboat, and to do so, Difficult to operate by women and because the design is based on hydraulics Furthermore, the problem of maintenance management is critical.

Disclosure of invention The present invention overcomes or at least substantially alleviates the above problems and uses If you intend to use a safe and reliable remote control device, Ru.

Therefore, the present invention is a remote control device for controlling a tugboat, which connects the tugboat with a cable. (i) a towboat for enabling the towboat to travel at a desired speed; and (li) transmit steering commands to the tugboat. The control device includes a control unit configured to control the speed of the power source. , or a Hall effect sensor to enable the transmission of steering commands. A remote control device is folded down, characterized in that it is combined with a control unit.

Two Hall effect sensors are located within the control unit, one sensor is connected to the power source. One sensor allows for speed control and the other sensor allows for the transmission of steering commands. is preferable.

Hall effect sensors are used, for example, in Pembroke, Concord, New Hampshire, USA. Sprague Electric Company located at 70 03301 Rok Road. It is commercially available. These sensors are electromagnets, permanent magnets or magnetically biased. The Hall effect is used to detect motion, position, or changes in the applied magnetic field of ferromagnetic materials. (discovered by E.F. Hall in 1879).

A Hall effect sensor is a sensor in which a constant voltage source is passed through a small sheet of semiconductor 44 material. A sensor configured to force a bias current to flow. If a magnetic field exists If not, the output, i.e. the voltage measured across the width of the sheet, will be zero. It becomes close to. According to the Hall effect, if a biased Hall effect sensor If placed in a magnetic field oriented at right angles to the Hall current, the voltage output Ill is proportional to the strength.

A basic pole effect sensor basically works if the applied magnetic field is in the form of a single tone. If there is a change in the output voltage, it is the transducer that responds to the output voltage. Ho One of the most important features of the Hall effect sensor, and in this invention the Hall effect sensor One feature that makes it effective is that the sensor must be in contact with the magnet to be activated. There is no such thing. Therefore, it is possible to remove the Pall effect sensor from dyed materials, e.g. from water. It is possible to

Changing the magnetic field can be done in various ways. Two of these methods are particularly suitable for the present invention.

The first method is to move the magnet across the working surface of the Hall effect sensor from one side to the other. This occurs when moving in the so-called "slide-by" mode.Second This method uses a rotating operation in which the magnet is rotated in a plane perpendicular to the active surface of the sensor. rotary activation.

r) occurs when

In the present invention, the sensor that enables control of the power source is placed in "sliding" mode using a magnet. It is preferable to operate at

Furthermore, it is preferable that the sensor that transmits the steering command is operated by a magnetic rotor. stomach. The magnet in each case can be ferromagnetic. The magnet is made of rare earth alloy or Preferably, it is made of samarium cobalt. The reason is the latter.) - Strong and sturdy, and allows for a larger space between the magnet and the Hall effect sensor. This is because it is possible to set a pace.

Commercially available sensors do not allow water to flow freely as encountered in the control device of the present invention. Can be fixed and completely sealed making it extremely suitable for crowded environments. Ru.

This Hall effect sensor includes a DC booster to increase the level of the signal, if desired. A width gauge can be incorporated.

In the device of the invention, each control unit (to increase or decrease the towing speed) Operates both the power source sensor (for steering) and the steering command sensor (for affecting steering). A pair of control handles can be included that can be controlled. This control unit One can operate the power source sensor while the other can operate the steering command sensor. A pair of control handles can be included to operate the sensor.

Additionally, a single unit that can operate both the power source sensor and the steering command sensor is also available. It is also possible to fold down the control unit for only the control handle.

In a preferred embodiment of the invention, the remote control device is also capable of being towed in case of an emergency. Includes a safety release device to stop the vessel.

The safety release device has one end attached to the skier and the other end attached to the control unit. A cord or similar member attached to a magnet, such that the magnet is magnetically absorbing. It is particularly preferred that the control unit be held in contact with the control unit by a pull. This way The magnetic field created by the sensor device, such as a reed relay, keeps the power supply operating. make it work.

If the skier drops the control handle, the cord removes the magnet from the control unit. pull, the magnetic field disappears, and the power supply becomes inoperable. As a result, the tugboat stops.

Speed to set a limit on the maximum speed of the towboat, especially for inexperienced skiers It may be convenient to provide a control device. The maximum speed control device is the control unit The magnetic rotor placed outside the and the selected highest placed inside the control unit Hall effect sensor that detects the speed and allows the towboat to speed up to 114m and may include.

The skier can achieve maximum skiing by rotating the rotor to the desired degree before starting skiing. A desired speed can be set in advance. After that, power source control/1nd (or several handles) to speed up to preset limits. enhance Speed can of course be reduced using the control handle during skiing can.

A float can be provided to prevent submersion of the control unit. system Preferably, the float is configured such that the control unit occupies a predetermined position in the water. Yes.

Ideally, the tugboat to which the remote control device of the present invention is connected is for supporting a power source. propelled by a jet constructed of sufficient size and capable of traveling at the desired speed. It is a boat with a single hull that is propelled. The device of the present invention has a driver and a driver inside the tugboat. Towboats are now used as skiports, as they eliminate the need for skiers and observers to board. It is possible to have a smaller τJ method than the one used.

The cable that connects the control unit to the tugboat transmits commands issued from the control unit. accessible and any wiring can be protected from contact with water. It should be.

The power source is typically a jet engine, but may be of any suitable type. I can do it.

When moving in direction A, the emitted signal is changed. The magnet 50 has the north pole From the point located at Do JJ- of the When the sensor moves to a position below the sensor 52, an electrical signal is generated. It changes from the value of iT2 through zero to a negative value.

This configuration has two advantages for use in the remote control device of the present invention. vinegar That is, the signal is weaker due to the spacing of the magnetic sensors, and the signal is weaker over the central region. It is approximately a linear function of the position of the magnet.

The variant shown in Figure 7 is a vertically oriented Hall hole that responds to horizontal magnetic field components. It has a rate sensor.

The magnet 50 can rotate around the central axis 53 as shown by arrow B; This produces a zero signal when the magnetic field is along the sensor plate, and The maximum positive or negative signal is at +900 or -90' from the zero position.
