Definitions
- the invention relates to a self-steering system for watercraft, in particular for sports boats and sailing yachts, with an automatic adjusting device by means of which a rudder system of the watercraft can be adjusted.
- the self-steering systems described above are able to keep a watercraft on course with sufficient safety and to offer the mostly small crew enough relief from the monotonous work on the steering gear.
- the control accuracy of the electronic self-steering systems is far higher when it functions properly than with a human helmets or watercraft drivers.
- the invention is based on the object of developing the self-steering system for watercraft described at the outset in such a way that in the event that the skipper or watercraft driver gets overboard, the watercraft will continue to be prevented from continuing on the course set in the self-steering system becomes.
- a transmission unit which is designed separately from the actuating device and can be attached to the watercraft operator or skipper, and by means of which a "man overboard” signal can be transmitted
- a reception unit which is assigned to the actuating device and by means of which a "man overboard” signal emitted by the transmitting unit can be received and the control device and thus the rudder system can be influenced in such a way that the distance between the watercraft and the transmitter unit does not increase.
- the receiving unit when receiving the "man over board” signal, influences the actuating device in such a way that the watercraft is placed in the wind by adjusting the rudder system.
- the actuating device advantageously includes a mechanically acting wind vane.
- the self-steering system can expediently have an electronic control unit, into which course data and the like. can be entered and in which this course data can be processed with other parameters that can be entered, for example wind and flow speeds and directions, into output signals which can be entered by the control unit into the actuating device, the receiving unit being connected to the electronic control unit and one of the Received "man overboard” signal processed there, entered into the control unit and there until the entrance of the "man Program running overboard "signal interrupts.
- the intelligent software used in the self-steering system according to the invention is able to use the detected sea state behavior and the general dynamics to calculate conclusions about the types of watercraft, the sea behavior of the watercraft and the wind conditions.
- Such an electronic control unit is advantageously designed as a fluxgate compass system.
- the rotational dynamics of the watercraft can be checked by evaluating the directional information provided by the compass system.
- the rotational dynamics e.g. the speed of rotation of the watercraft, the wind direction can be determined, for example, without the use of a wind measuring device.
- the actuating device can be designed as a servo motor in a relatively simple manner.
- tiller control is provided in the watercraft, it is expedient if the servomotor is designed as a linear motor. If the watercraft is equipped with a mechanical wheel control, a motor with gear drive is expediently provided as the servomotor.
- the servo motor should advantageously be designed as a hydraulic pump.
- the transmitter unit In order to reliably ensure the functionality of the transmitter unit in use, the transmitter unit has a water-tight encapsulated housing, so that the ingress of water and the associated functional impairments are prevented.
- the transmitter unit has a Velcro strap, it can easily or the like on the collar of a life jacket. be brought up.
- the transmitter unit is equipped with a carrying chain, it can be worn around the neck of the skipper or the watercraft operator in a simple manner.
- the transmitter unit gets to the water surface from where it can transmit, it is expediently constructed in such a way that buoyancy force acts on it in the water.
- the transmitter unit is both automatic and can also be triggered manually. In certain cases of request, however, it can also be expedient to design the transmitter unit to be triggered automatically or manually.
- Automatic triggering of the transmitter unit can be achieved in a simple manner if the transmitter unit has a triggering device which puts the transmitter unit into operation when it comes into contact with water. With such a configuration, the transmitter unit is also put into operation if the watercraft skipper loses consciousness in the event that led to his overboard passage and accordingly, after being in the water, is unable to do so himself Triggering the transmitter unit.
- the triggering device of the transmission unit is splash-proof.
- the transmitter unit can also advantageously be put into operation by a pressure switch which can be actuated manually.
- This pressure switch can always be operated by the skipper or watercraft operator when he is not unconscious. This possibility is particularly advantageous in cases of unclear automatic triggering.
- the transmission of the coded, digitized "man over board” signal by the transmitter unit should advantageously be carried out continuously, so that reliable reception 8 - the "man overboard” signal is guaranteed by the receiving unit.
- the radiation of the "man over board” signal in an uninterrupted sequence is important because radiation of the signal mentioned under water is not possible for technical reasons.
- only a permanent emission of the "man overboard” signal by the transmitter unit ensures that the signal mentioned will be received by the receiver unit at some point becomes.
- a permanent test signal is transmitted by means of the transmitting unit and the self-steering system has an alarm device which emits an alarm signal when the permanent test signal is not received in the receiving unit, it is ensured that the radio link between the transmitting and Receiving unit is immediately determined.
- the autopilot has a non-dead man's circuit with adjustable response time of the transmitting unit carrying skipper or water vehicle operator has in a false alarm, the ability to delete within the • by the set reaction time limited period of time the false alarm and so a Heave of the vessel to prevent.
- the power supply to the transmitter unit is advantageous via a 9V block battery.
- the receiver unit To ensure the functionality of the receiver unit, it is also provided with a waterproof, encapsulated housing.
- This waterproof, encapsulated housing and thus the receiver unit are arranged in close proximity to the control unit of the self-steering system.
- the receiving unit advantageously has an external antenna, which is expediently as high as possible, i.e. is mounted on the mast or on the equipment carrier, on board the watercraft. This ensures that the "man over board" signal is received as free of interference as possible, and this also applies to the most adverse sea conditions.
- Suitable inputs are: inputs of a wind vane to be connected or a cable remote control or an input for connecting a GPS or Decca navigator.
- the control unit is able, by means of suitable sensors, to heel the watercraft or the sailing yacht, i.e. to determine the heeling direction and thus the direction of the incident wind with respect to the longitudinal axis of the ship.
- the heel can also be reliably determined in heavy seas become, which is particularly important with regard to smaller sailing yachts, since such sailing yachts can be thrown back and forth heavily in rough seas.
- the receiving unit expediently contains a separate switch output, which can have, for example, a 12V or 24V output voltage, with which simple switching functions can be performed.
- the receiving unit is able, for example, to switch off the engine of the watercraft, for example, via connected relays, so that motor yachts can also be stopped.
- the invention relates to a device for decommissioning the self-steering system of a watercraft, this device having the transmission unit and the reception unit described above and being installable in an existing self-steering system.
- An electronic self-steering system shown in the single figure serves for the automatic control of watercraft, in particular of sports boats and sailing yachts.
- Such watercraft have a rudder system 1, by means of which the direction of travel of the watercraft can be changed.
- a control device 2 is connected to the rudder system 1 and can be configured, for example, as a servo motor.
- This actuating device 2 performs adjustments and adjustments the rudder system 1 when it receives appropriate control signals from an electronic control unit 3 of the self-steering system.
- a reception unit 4 is connected to the electronic control unit 3 and has an external antenna 5, in which a "man over board" signal 6 can be received, which is emitted by a transmission unit 7 when the skipper or watercraft operator, the the transmitter unit 7 wears in a suitable form on the body, has gone overboard.
- the transmitter unit 7 is put into operation and, as mentioned above, emits the “man overboard” signal. This is received by the external antenna 5 of the receiving unit 4.
- the receiving unit 4 transmits a signal to the electronic control unit 3 indicating the reception of a "man over board” signal 6, in which the electronics located there logically apply control signals to the actuating device 2 as a function of the heeling position or the signals from mechanical sensors, which cause the sailing yacht to shoot in the wind.
- the sensors connected to the electronic control unit measure the transfer of the sailing yacht to the other bow and the electronic control unit 3 inputs corresponding control signals into the adjusting device 2, whereupon the latter sets the rudder system 1 in the opposite direction.
- the sailing yacht then remains turned with the jib standing behind.
- the sailing yacht is equipped with a self-tacking jib, the sailing yacht is constantly driven by the wind.
- a control routine "measure heeling and turn rudder opposite" is practically executed. The sailing yacht then also stays there.
- the subunit of the self-steering system according to the invention consisting of the receiving unit 4 and the transmitting unit 7, can be used in conjunction with conventional control units of commercially available self-steering systems. These control units have the usual adjusting devices, which are designed as servomotors or hydraulic pumps and transmit the desired course change of the watercraft to the steering gear.
- the sub-unit consisting of the receiving unit 4 and the transmitting unit 7 does not require its own servomotors, so that conventional self-steering systems can be easily combined with the sub-unit comprising the receiving unit 4 without major changes and transmitter unit 7 can be equipped, the installation outlay being comparatively low.
