Description

Description Title of the invention: AUTOMATION DEVICE FOR A WINCH, AUTOMATED WINCH AND METHOD ASSOCIATED INSTALLATION technical field

[0001] = The present invention relates to the technical field of nautical equipment and, more particularly, accessories used on sailboats. It concerns more specifically- technically an automated or semi-automated winch, that is to say a winch in which at least one maneuver can be performed by means of a motor.

[0002] = More specifically, the invention relates to a winch automation device, a automated winch and a method for installing the automation device. State of the art

[0003] — Generally speaking, a sailboat includes one or more devices called "winches," which are winches around which a rope, also called end, winds and unwinds, for example to trim sheets or hoist a sail. A winch consists of a drum around which the end can be wound to achieve a maneuver. Generally, the doll is rotated by a crank used by a user.

[0004] = To limit the forces and improve the winding speed of the end around the winch drum, it is also possible to use an automated winch, that is to say in which a motor drives the rotating doll.

[0005] Thus, there are now manual winches, automated winches, and winches with motorized assistance. Document FR 3 055 619 describes, for example, the structure of a State-of-the-art motorized winch.

[0006] = In manual or motor-assisted winches, the user feels a feedback haptic feedback during winch operation, allowing him to feel the tension applied to the end by winch.

[0007] — This feeling of the efforts exerted on the rope thanks to haptic feedback is essential for two reasons. First, in terms of security, as soon as the user feels a If the effort is too great relative to the maneuver being performed, it may detect a problem. and stop the maneuver before breaking something. Furthermore, this "feeling" is also very important in sailing practice so that the user can adjust correctly its maneuver (halyard tension, backstay tension, etc.).

[0008] There are a large number of distinct maneuvers that can be performed on a sailboat, such as tacking, reefing, gybing, raising the mainsail sail, genoa sheeting, mainsail sheeting, spinnaker hoisting, sheeting of a spinnaker, tightening the backstays, furling a headsail… In all these maneuvers, it is essential to execute them quickly because, until the maneuver is complete, the boat is in a transitional, unstable, and uncomfortable state, with sails flapping and becoming damaged. Therefore, the aim is to complete the maneuver as quickly as possible to return to a perfectly stable situation and avoid any risk to the equipment. In the example of a maneuver involving raising the mainsail, the goal is to hoist the sail by unfurling it, with the boat facing into the wind, without breaking or tearing anything. However, during this maneuver, the mainsail slides can get stuck, battens can become entangled in a lazy jack line, or reefing lines can obstruct the raising of the mainsail… For another example of a maneuver involving tacking the genoa, the objective is to release the leeward sheet, then take up the sheet on the other tack at the same time as the boat passes head to wind, the genoa then passes on the other tack and the genoa is gradually sheeted in. During this maneuver, a knot can form at the entrance of the sheet car pulley and jam, a sheet can get caught on a mast step or other spar on the deck… In the example of a maneuver involving reefing, the goal is to reduce the area of ​​the mainsail. This maneuver is performed in strong wind conditions, when there is significant stress on the boat, and therefore requires particular vigilance. The transition phase involves reefing the mainsail. First, the mainsail is aligned with the wind, then the reefing line is taken up while simultaneously releasing the mainsail halyard. During this maneuver, a slide can get stuck and, if you continue to force it by increasing the pulling force too much on the reefing line, you risk tearing the mainsail. For another example of a maneuver consisting of hoisting a spinnaker, during the transitional phase of the maneuver, that is to say before tensioning, a jamming situation may occur, in particular if the halyard's snap hook gets caught on a sheave or if the halyard catches on a spreader bar. Consequently, a large number of problems can arise during a maneuver. Furthermore, depending on the maneuvers performed, and the phases of these maneuvers, particularly between the transitional and final phases, the levels of force exerted on the winch vary considerably. In order to limit the duration of the transitional phase, that is to say the phase during which the If the boat is unstable, automated winches are very efficient since they are able to operate the winch at a much higher speed than a manual or motorized maneuver. To manage the need for speed variation on the winch, typically between the transition and final phases, manual or automatic winches generally incorporate two different speeds achieved with distinct gear ratios. To manage the variations in force applied to an automated winch, document EP 2 179 959 proposes detecting the gear ratio used by the winch and setting the torque applied by the electric motor coupled to the winch based on the detected gear ratio. However, this solution does not allow for adaptation to the wide variability of maneuvers that can be used with a winch. For example, using the solution in document EP 2 179 959, it is possible to set two distinct limits for a winch with a 60% efficiency, a first speed with a power ratio of 11, and a second speed with a power ratio of 46. For the first speed, the limit can be set at 25 kg, so that the maximum pull on the line can reach 165 kg (25 x 11 x 0.6). For the second speed, the limit can be set at 20 kg, so that the maximum pull on the line can reach 552 kg (20 x 46 x 0.6). These values ​​are suitable for hoisting the mainsail in first speed and tightening it in second speed. However, for other maneuvers, these limits may be too restrictive for performing the maneuver at full speed, or too broad to minimize the risk of damaging equipment. Thus, even with the solution described in document EP 2 179 959, the major problem with automated winches lies in the risk of equipment breakage when excessive tension is applied to a line or sail. Currently, with an automated winch, it is not uncommon to break equipment or even tear a sail. To address this technical problem, it would be possible to use a torque limiting system imposed by the automated winch. However, torque limitation is extremely complex to implement in practice since a winch is generally used for a large number of distinct maneuvers, and the torques used for these different maneuvers are also highly variable. Thus, by sizing an automated winch with a low-power electric motor so as to prevent the winch from having the power necessary to break equipment, the power of the winch could be insufficient for certain maneuvers, particularly during the final phases, and this power could nevertheless be sufficient to damage equipment. The technical problem with the invention is therefore to find out how to obtain a winch. automated allowing a crew member to effortlessly operate the winch, correctly adjusting its maneuver, while protecting the equipment during the various maneuvers. Description of the invention To address this technical problem, the invention proposes using a human-machine interface with a memory in which maneuvers are pre-recorded along with the force limits associated with each maneuver. The human-machine interface allows a user to select the desired maneuver and to obtain information on the force exerted over time during the maneuver. Thus, the user can obtain information on the effort involved and verify, during the maneuver, that the effort involved is not excessive compared to the pre-recorded limit effort for the selected maneuver. According to a first aspect, the invention relates to a winch automation device comprising a drum for receiving a line to perform a maneuver, said automation device comprising: a motor intended to engage the said winch drum; and a motor monitoring device capable of fixing the torque applied by the motor to the doll. The invention is characterized in that the device also comprises: a memory incorporating a set of pre-recorded maneuvers, each maneuver being associated with at least one limit effort; means of measuring the force exerted on the winch; and a human-machine interface, connected to the supervisory unit, comprising: means of actuation of the engine; means of selecting a maneuver from among the set of pre-recorded maneuvers; and at least one display capable of transmitting to a winch user information on the force exerted on the winch and information on the expected limit force for the selected maneuver. Thus, the invention relates to a winch automation device. This automation device can be installed during boat construction at the same time as the winch is installed. Alternatively, this device can be retrofitted to an existing winch on a boat. Furthermore, the winch's actuation motor can be either an electric or hydraulic motor without altering the invention. Furthermore, this device can provide the sole means of winch actuation, thus achieving a fully automated winch. Mechanical means can also to allow the motor to be disengaged to allow manual operation of the winch, thus forming a semi-automated winch. The invention thus provides the user with two crucial pieces of information: the force applied to the winch and the expected force limit for the selected maneuver. This information allows the user to maintain control over the applied force, even during transitional phases. Similar to the haptic feedback felt by the user when a winch is operated manually, this information transmitted via the human-machine interface enables the user to fine-tune their maneuver with a high degree of safety for the equipment. Regarding the effort exerted on the winch, it can be estimated or measured in several ways. According to a first variant, the motor corresponding to an electric motor, the effort exerted on the winch is estimated from the electrical power consumed by the motor. In practice, the motor is often an electric motor powered by a fixed voltage, while the motor's supply current can vary. It is therefore possible to characterize the motor torque as a function of the current applied to the motor and the motor's rotational speed. By measuring the motor's supply current and knowing its rotational speed, it is possible to determine the torque exerted by the motor at any given time. Knowing the reduction ratio of the electric motor, the different reduction ratios of the motorized winch, and the winch's efficiency, it is possible to calculate the tension force exerted by the line on the winch at any given time, which is directly proportional to the motor torque. Thus, when the winch has two directions of rotation associated with different reduction ratios, the force exerted as a function of the current differs depending on the selected direction of rotation. This first variant of obtaining the effort involved allows us to obtain information with an accuracy of around 10% with the effort actually measured on the tip. According to a second variant, the force exerted on the winch is measured using at least one strain gauge mounted between a moving part of the winch or the engine and a fixed part. For example, the moving part could be an epicyclic gear train of the engine or a gear of the winch, while the fixed part could be a casing of the engine. These strain gauges provide information on the tension exerted on the winch due to the line tension, and therefore on the torque applied to the line. Besides the method of obtaining the effort applied to the winch, this information can be displayed on the human-machine interface in several ways. Indeed, the effort involved can be expressed in kilograms, equivalent to the force exerted by a winch handle. The effort involved can also be expressed as the tension on the rope at the winch exit. To do this, it is necessary to know precisely the characteristics of the winch because the effort in the rope is not only a function of the torque exerted by the motor on the drive shaft of the winch, but also a function of the reduction ratio of the winch in the speed considered, and of course also a function of the efficiency of the winch. Regardless of how the effort exerted on the human-machine interface is expressed (kilograms equivalent to the effort exerted by a crank or rope tension at the winch output), the limit forces of each maneuver are displayed with the same expression. These limit forces can only be used as information for the user, so that they can compare the force currently applied to the winch with the force expected for the maneuver in progress, or for an adjustment (backstay tension, halyard tension, etc.) by approaching what they are used to doing with their traditional winch handle. Preferably, the monitoring device includes a torque limiter configured to limit the engine torque when the force applied to the winch reaches the limit force recorded for the selected maneuver. Thus, even if the user does not monitor the human-machine interface to detect an exceedance of the recorded force limit for the selected maneuver, the monitoring device can be configured to impose a torque limit on the winch for each maneuver Preferably, the human-machine interface incorporates means for modifying the maximum force for the selected maneuver. This modification of the maximum force can be performed during the maneuver to bypass the limit imposed by the torque limiter. Furthermore, this modification of the limit effort may or may not be recorded in memory so that it can be reused for a future maneuver of the same nature. For each type of maneuver, the user can therefore record the maximum force limits they wish to avoid. These limits can differ for various winch speeds. Thus, by iteratively adjusting the limits to suit their needs, the user can create a set of pre-recorded maneuvers. For example, a maneuver might involve raising the mainsail with a limit in first gear of 19.7 kg of equivalent force on a winch handle, or 130 kg of tension on the line, and a limit in second gear of 4.7 kg equivalent force on a crank, or also 130 kg of tension on the end. Another maneuver could correspond to the tensioning of a halyard with a limit in a first speed of 30 kg of equivalent force on a crank, or 198 kg of tension on the end, and a limit in a second speed of 25 kg of equivalent force on a crank, or 690 kg of tension on the end. By storing changes in effort limits in memory, the user can thus modify their preferences over time according to their feelings. Furthermore, this value can also be modified from an administration console. For example, the monitoring device and / or the human-machine interface can integrate wireless communication with a portable device on which an administration console allows the human-machine interface and / or monitoring device parameters to be adjusted. For example, from the human-machine interface or from the administration console, it is possible to modify the brightness, the writing size, the language of the human-machine interface, the winch parameters allowing you to obtain the forces involved, the limit forces associated with the different maneuvers recorded in memory, and add new maneuvers. Furthermore, this device can be attached to any type of winch by sizing the motor according to the characteristics of the winch. According to a second aspect, the invention relates to an automated winch comprising: a doll designed to receive a end to perform a maneuver; and an automation device for the winch according to the first aspect of the invention. Preferably, the winch automation device motor is an electric motor powered by an associated battery. In existing automated winches, the electric motor is typically powered by an electrical supply from the boat's integrated electrical system. However, to provide the necessary power to run the motor, a high-capacity electrical system is often required. This is because boat service batteries are typically 12 or 24 volts, and powering electric winch motors requires thick cables, typically with a cross-section of 35 mm², to carry currents that can exceed 100 amps. However, the integration and routing of these power electrical cables inside a boat poses a large number of installation constraints. By using a battery to power the electric motor, there is no need to run high-power electrical cables inside the boat, and low-power cables may be sufficient to recharge the battery when the winch is not in use. For this purpose, the battery is preferably... connected to a charging circuit with a voltage of less than 40 volts and a current of less than 3 amps. Preferably, the motor is a brushless motor coupled with a gear reducer. A brushless motor is also called a "brushless" motor in English-language literature. A gear reducer can correspond to an epicyclic gear train followed by a possible right-angle drive device to facilitate the integration of the motor under the winch. In conventional winch motors, the motors consist of a DC motor coupled to a worm gear reducer, with an overall efficiency of around 30%. With this embodiment of the invention, using a brushless motor coupled to a gear reducer, the overall motor efficiency can reach around 60%, thus limiting energy losses. Furthermore, to achieve the same effort, the electrical power required to power a brushless motor with a gear reducer can be lower than that required to power a DC motor with a worm gear reducer. Therefore, for the same voltage, it is possible to limit the current required to power a brushless motor with a gear reducer. For example, to obtain a mechanical power of around 500 watts, current motors require a current of 138 amps, and this embodiment allows the use of only 28 amps. It follows that it is possible to use a 6 mm² cross-section cable between the battery and the motor instead of a 35 mm² cable. The human-machine interface can also display information about the battery charge level. Thus, the human-machine interface includes at least one screen to display the applied force, at least one force limit associated with the selected maneuver, possibly a description of the selected maneuver, possibly the selected winch speed, possibly the battery charge level, and possibly the next and previous maneuvers so that the user can easily switch between them. Indeed, to select the maneuver, the human-machine interface may incorporate push buttons to switch from one maneuver to another. In addition to the maneuver selection buttons, the human-machine interface may include two means of motor actuation for each direction of winch rotation. Preferably, motor actuation is conditional upon the use of a "dead man's switch" type control, requiring the user to press at least two buttons to initiate motor operation so that a non-press Intentionally pressing a button does not cause the engine to start. In addition, the human-machine interface can be connected via wired or wireless connection to the supervisory unit. According to a third aspect, the invention relates to a method for installing an automation device according to the first aspect of the invention, the method comprising the following steps: installation of the engine, the monitoring unit and the human-machine interface; defining the winch type in an administration console; downloading, from a server, the limit forces associated with the type of winch defined for different maneuvers; recording of limit efforts in memory; and human-machine interface configuration according to user preferences. Brief description of the drawings The method of implementing the invention, as well as the resulting advantages, will become clear from the description of the embodiments that follow, supported by the attached figures in which: [Fig.1] Fig.1 is a schematic representation of an automated winch according to one embodiment of the invention: [Fig.2] The [Fig.2] is a perspective view of the human-machine interface of an implementation of the automated winch of the [Fig.1]; [Fig. 3] Fig. 3 is a schematic, partially cross-sectional representation of one implementation of the automated winch motor shown in Fig. 1; and [Fig.4] The [Fig.4] is a representation of part of a database containing characteristics of different winches. Detailed description of the implementation methods Figure 1 illustrates an automated winch according to an embodiment of the invention. The winch comprises a base 1 fixed to a hull 0 of a boat and a drum 2 movable in rotation about a main transmission axis 3. More specifically, the doll 2 has an upper part 2.1 which allows a boot 6 to be held during its winding around a central part 2.3 of the doll 2. A pivot joint 2.2 is formed between the doll 2 and the shell 1 so that the doll 2 is mobile in rotation. In a manual winch, the rotational movement of the drum 2 is exerted by a winch handle fixed in a housing 3.1. This housing 3.1 drives two gear trains 4 and 5 in rotation. These two gear trains allow the drum 2 to be rotated in the same direction of rotation but with different speeds. Thus, gears 4.1 and 4.2 of gear train 4 allow the direction of rotation applied to the main transmission shaft 3 to be reversed. When a movement is applied in one direction of rotation to the main transmission shaft 3, only the epicyclic gear train 4 is engaged to drive the headstock 2 at a first speed. Conversely, when the main transmission shaft 3 is driven in the opposite direction of rotation, only the epicyclic gear train 5 is engaged, with gears 5.1 and 5.2 imposing a reduction ratio that limits the speed of the headstock 2. Thus, a classic winch has a transmission shaft 3 allowing it to support two directions of rotation so as to drive a drum 2 with two distinct speeds and the same direction of rotation. Of course, all mechanical configurations can be considered without changing the invention. Regardless of the mechanical configuration of the winch used, the invention proposes to automate the winch by driving the main transmission shaft 3 with a motor 12, preferably an electric motor. To achieve this, the lower part 3.2 of the main transmission shaft 3 can be coupled to the rotor of the motor 12. More specifically, as illustrated in [Fig.3], the rotor of the motor 12 can extend perpendicularly to the main transmission axis 3 so as to limit the size of the automation device. For example, the rotor of the motor 12 can be fixed to an epicyclic gear train 10, the output of which is connected to a pinion 9 supported by a bearing 9-1. A gear 8 then connects the pinion 9 to the main transmission shaft 3 of the winch. Preferably, a fan 13 is placed near the motor 12 to ensure its cooling, and the motor 12 is protected by a housing 16. In addition to the mechanical elements, the motor 12 can be electrically powered by a supervisory unit 15 integrated into the housing 16 of the motor 12. The supervisory unit 15 corresponds, for example, to a motherboard integrating a processor and a power control circuit 19 of the motor 12. As illustrated in [Fig.3], this supervisory unit 15 may have connectors 15-1 accessible by opening a cover 14. Preferably, the motor 12 corresponds to an electric motor and the power supply of the motor 12 is provided by a battery 23 via the power control circuit 19 of the supervisory unit 15. Battery 23 can be placed under motor 12, which is itself placed under the winch, but it can also be mobile depending on implementation constraints and positioned anywhere on the boat. Thus, the power supply for motor 12 can be provided directly by battery 23 without having to to carry a significant amount of electrical power along the hull 0 of the boat. Apart from the phases of use of the battery 23 to power the motor 12, a charging circuit 25 can be implemented by the supervisory unit 15 by recovering the available energy from a low voltage network 25, typically a network 25 with a voltage of less than 40 volts and a current of less than 3 amps. This network 25 may correspond to a cable that carries power from the boat's service batteries, typically in 12 or 24 volts. The monitoring unit 15 can be powered solely by the battery 23 or by the battery 23 and the charging circuit 25. In addition, the supervisory unit 15 can integrate wireless receiving means 21 in order to communicate with a portable device 38, such as a smartphone or a touch tablet. Furthermore, the supervisory unit 15 is connected with the human-machine interface 26. The connection between the human-machine interface 26 and the supervisory unit 15 can be made wired or wireless, for example using wireless communication means 21. The human-machine interface allows the user to select the maneuver they wish to perform and to control the motor 12 in the first or second speed. To start the motor 12 from the human-machine interface 26, the user can press a button 35 to activate the motor 12 in the first speed or a button 36 to activate the motor 12 in the second speed. An example of a human-machine interface 26 is shown in [Fig. 2]. In addition, to ensure the safety of the automation device, the user should preferably press simultaneously one of the buttons 35 or 36 and a second button 37 to ensure that the user operates at least two buttons simultaneously when he wants to start the rotation of the winch. Buttons 35 and 36 may correspond to push buttons while button 37 may correspond to a potentiometer allowing adjustment of the rotation speed according to the force of pressure on button 37. According to the invention, when the user operates the winch, they receive information on the human-machine interface 26 regarding the force exerted 28 on the winch. This force exerted 28 on the winch can be measured by strain gauges or estimated from the electrical power transmitted to the motor 12. To display the applied force 28, the human-machine interface 26 has a display 27, for example a screen, on which the applied force 28 is displayed and updated in real time, for example every tenth of a second. In addition to the applied force 28, the screen 27 also displays information on the expected limit force 30, 31 for the selected maneuver 29. In the example in [Fig. 1], the screen 27 displays the limits Expected values ​​of 30 and 31 are for the two winch rotation speeds. Alternatively, a single limit force can be displayed by detecting the direction of rotation selected by the user. In addition to this information on the effort involved 28 and the limit effort 30, 31, the selected maneuver 29 can also be displayed on the screen 27 so that the user can confirm that he has selected the correct desired maneuver. To select the maneuver to be performed, the human-machine interface 26 preferentially presents maneuver selection buttons 34. For example, if the winch is configured to perform four maneuvers, the human-machine interface 26 may have four buttons 34 to select one of the four maneuvers. In practice, the number of maneuvers is often very large, and it is preferable to use the human-machine interface 26 to allow the user to select the desired maneuver 29 by scrolling through the pre-recorded maneuvers. Thus, on the human-machine interface 26, the screen 27 can also display the previous maneuver 32 and the next maneuver 33, thereby facilitating the scrolling through the different maneuvers offered so that the user can select the desired maneuver. The maneuver selection buttons 34 can also be used to configure some of the information displayed in the human-machine interface 26 or the limit forces 30, 31. For example, of the four buttons 34, two can be used to select the desired maneuver, and two others can be used to raise or lower the expected limit for the current maneuver and the speed being used. Thus, the user can potentially modify the pre-recorded values ​​of the limit forces 30, 31 to suit their perception of the maneuver being performed. Of course, many other parameters can be modified through the human-machine interface 26, such as brightness, language, and font size. In addition, other parameters can be set from an administration console running on the portable device 38. For example, this administration console can be from a mobile application for smartphone or tablet that the user can download from an application store. This administration console is particularly useful when the user wants to install the automation device on an existing winch, as they can then enter the winch's characteristics and use the administration console to connect to a server where limit forces are pre-recorded for different winch types, as illustrated in [Fig. 4]. By downloading the limit forces 30, 31 for different maneuvers and for the specific winch, these limit forces 30, 31 can be stored in a memory 22 of the supervisory unit 15. Alternatively, the memory 22 can be located in the human-machine interface 26. The human-machine interface 26 is configured to display the limit forces 30, 31 of the maneuvers pre-recorded in this memory 22. Furthermore, this administration console can prove particularly interesting for analyzing usage data (history, operating time, forces involved by type of maneuver, etc.). An example of information stored on the remote server is shown in [Fig.4] with different winch brands, different winch types and different sizes. From these winch characteristics, it is possible to obtain the reduction ratios and the winch efficiency allowing us to estimate, from the electrical power consumed by the motor 12, the effort exerted 28 on the winch. With the winch's applied force 28 and the expected limit force 30, 31 for the selected maneuver 29 obtained, the user can now operate a winch effortlessly, while receiving feedback for this maneuver. By regularly monitoring this information available on the human-machine interface 26, the user can therefore limit the risk of equipment damage during various maneuvers, while benefiting from very fast maneuvers to minimize transitional phases. Furthermore, if the user wishes to limit the attention he has to pay to the human-machine interface 26 during maneuvers, the automation device can also include a torque limiter configured to limit the torque of the motor 12 when the effort engaged 28 reaches the expected limit effort 30, 31 for the selected speed and maneuver 29. Thus, the invention proposes to provide new information associated with a winch to facilitate winch control in the various possible maneuvers of a boat, while benefiting from quick maneuvers and limiting the risk of equipment breakage or sail tearing.
