Description

: einu .viar 10 15 20 25 30 no a I. o u I o u c According to the concept of invention, the control and monitoring system in question must be arranged with a switchable and disconnectable unit, in the connected position of which a control and / or monitoring system complete for function exists and in whose second position an incomplete system thus exists. Despite the relatively complex component and functional structure of the system, the said connection and disconnection function must be able to be arranged technically simple and uncritically from a system point of view. The invention also solves this problem.

In the case of associated types of means of subsistence, there is also a need to be able to identify the means of subsistence to one or more persons or owners who must have full or partial access to the means of subsistence in question. Thus, it should not be possible to use the means of communication unless the identification or green light function is present. The invention also solves this problem.

A relatively large number of components or parts of equipment must be able to be disconnected and brought by the person in question. The invention also solves this problem.

At e.g. boats, there may be problems with leaving components and equipment exposed to weather and wind (salt water, rain, etc.). There is thus a desire to disconnect the unit with its critical components and functions during temporary periods. It is thus, e.g. during winter storage and longer breaks, the need to easily remove sensitive and exposed components during the periods in question. There are also problems with arranging an exchange unit in the system mentioned in the introduction. At e.g. service and capacity changes and / or modernisations, there is a need to be able to replace an existing unit with components and functions of a first embodiment arranged in or near it with an outwardly corresponding unit with components and functions of a second embodiment. The system must thus be able to be updated or changed e.g. due to engine replacement where the new engines require new control and sensing coordinates or control and sensing data. In some cases, it may also be desirable to replace one control and / or monitoring system with another or to be able to coordinate an existing system with one or more other systems afterwards. The invention also solves this problem. 10 l5 20 25 30 na en n n u a o o I s; au What can mainly be considered as characteristic of a device of the type mentioned at the outset appears from the characteristic part of the following main requirement.

Further developments of the inventive concept appear from subclaims to said main claim.

Through the above proposed, prominent advantages are obtained in that in the case of means of transport with complicated and relatively extensive and expensive equipment can be gathered in a common unit which is arranged with the said connection and disconnection functions. The connectable and disconnectable unit can be designed to be easily carried and weigh relatively little. In the case of boats in particular, prominent advantages arise in that during the boat's winter storage you can bring the mentioned components and equipment that are not only prone to theft, but also sensitive to weather and wind. Components and their connections are often exposed to a harsh environment (salt water, rain, rust, etc.).

The unit can thus be stored in a suitable environment in a storage place during the winter.

A presently proposed embodiment of a device which exhibits the key features significant to the invention shall be described in the following with simultaneous reference to the accompanying drawings, in which Figure 1 shows in horizontal view a boat provided with e.g. instrument panel and motors as well as waveguides extending between the instrument panel and the motors, figure 1a in horizontal view shows in principle a connectable and disconnectable unit enclosing and equipped with components, figure 2 in perspective obliquely from above shows the unit according to ñguren la mera i detail and arranged to the waveguide in question, aan; . but: »treat 10 15 20 25 30 figure 3 shows in principle the application of a component included in the unit according to figure 2 in connection with the waveguide in question, figure 4 in perspective obliquely from above shows the transfer function between waveguide and one of the boat's engines, figure 5 in perspective and top view shows parts of the arrangement according to figure 4, and figure 6 in Longitudinal section shows in more detail the structure and interaction of the unit with CAN systems.

With regard to the construction of a control and / or monitoring system useful in connection with the invention, Lex. a CAN system, reference is made to the Swedish patent applications mentioned above. In the present case, one or more spring conductors for microwaves shall be used for the transmission of information (control commands and data) between the modules and the units and the components used in the means of transport to be controlled and / or monitored.

In Figure 1, a means of transport in the form of a boat is shown by 201 and a waveguide arranged in the body or chassis of the boat is indicated by 202. The waveguide in question extends between an instrument panel 203 and the boat's engine or motors which in the present case are three in number and indicated by 204, 205 and 206. The engines in question have been shown as outboard engines, but of course the invention also works for inboard or inboard engines or combinations of inboard and outboard engines. The unit can then comprise the control means (steering wheel) 208 and in figure 1a internal components 209, 210 and 211 used in principle. and included in the unit 207. The unit is arranged to the waveguide 202 in a connectable and disconnectable manner not shown in figure 2. The component 211 is interoperable or connected to a radio gateway 211A which in the case shown is provided with an antenna 212 which extends through a recess (not shown) into the waveguide 202. The said component 211A communicates in the waveguide channel 202 with radio signals which are in principle indicated with 213. The waveguide's inner 202a may consist of a void or be filled with some kind of media, compare the said Swedish patents.

Figure 3 shows in broken lines the position of the component 211A, the antenna 212 of which extends into the interior 202a of the waveguide 202.

The communication 213 (cf. also figure 2) is in the case according to figure 4 intended to take place with one of said motors, e.g. the motor 204. In the manner specified in the said Swedish patent applications, the waveguide 202 is provided with signal sockets 202b to the motor 204 in question, whereby the control and / or monitoring of the motor 204 can take place via wireless connection by means of radio signals 213a. The motor is provided with or connected to two electrical conductors 204a and 204b where the conductor 204a is connected to a conductor 2020 arranged or attached to or on the body of the waveguide 202 and acting as a positive conductor. The conductor 204b is connected to the goods of the waveguide body which serves as ground potential. A battery or a direct current source are connected via conductors B ”and B” to the said conductor 202c and the goods of the waveguide body, respectively. B 'is connected to positive potential and B' to earth potential.

The respective motor (eg motor 204) is provided with a directional antenna 204 which is prevented by the directional function from receiving radiation from a direction other than the recess 202b.

In accordance with Figure 5, the unit 207 may comprise a waveguide part 214, which in accordance with the following is connectable to the waveguide 202. The components 208, 209, 210, 211, 211A are mutually communicable in the CAN system (see also the mentioned Swedish patent applications). . The internal communication in the unit 207 between two or fls of said components takes place via BUS connection, the parts of which between the components in Figure 5 are indicated by 215, 216, 217 and 217 ”. Said connecting parts may consist of -f-p o there were 10 15 20 25 30: ° .: ''. :.:. f::. ' f r); _, ",,". ' 2 'i .2 3. ".... 6: 2 wire connections and / or non-wired connections, eg optical connections, IR connections, electromagnetic connections, etc. Alternatively or in addition, fiber optic connections may be used. The connection 217' connects component 211A (radio gateway) to the BUS connection.

Figure 6 is intended to show examples of connectable unit 207. The unit can then be designed or connected to a connecting part which in Fig. 6 is indicated by 207a.

The connection part can be arranged to be part of a quick-connect function, the connection part 207a having a front part 207b designed as a male. The handle 207b can in the quick coupling function be interconnected with a female part 219. A locking part can be arranged for the parts, which in principle 6 is shown in 220. The locking part can be actuated by means of a spring function which may comprise one or more springs, Figure 6 showing in principle a spring 221. The locking part can work with balls or locking means 222, 223 which are arranged in guide grooves (not shown) on the outside of the male and female parts. Said locking part can be made in a number of different ways and reference is made here to the generally known technique for holding male and female parts together. The female part shows a space 219a for receiving the trade 207b. The female part is or can then be arranged in connection with said guide 202, parts of which are shown in figure 6. During the connection (made in figure 6) the male and female parts have joined the guide part 214 in the unit 207 with one end of the guide 202. Figure 6 is in principle shown sealing means 224 which have a shape and material which seals the inner space 202a of the waveguide and the inner space 214a of the waveguide part so that no prominent leakage of the energy conducted by the waveguide arrangement takes place. In the clock, said bus connection is indicated by 218 (cf. 215, 216, 217, 217 'in Figure 5). Figure 65 also indicates a connection 225 for the unit's power supply. The trade is provided with connection parts 218a, 218b and 225a, respectively, for said BUS connection (CAN, LIN, RS485, etc.) and conductor 225. The female part is provided with connection sleeve 226 for the waveguide part 214 and with connection sleeves 227, 228 and 229 for said wired conductors. . In the case of an optical connection, there are corresponding optical connection means. Additional modules or nodes 230, 231, 232 can be connected to the connection. The module or node 230 represents other components that can be included in the system. The module 232 cooperates via a wireless connection 233 with a system node or system module 234, which in turn can be connected to another controller via a wireless connection 235. and / or monitoring system 236 of the CAN type or other type. the arrangement with the modules or nodes 232 and 234 is arranged to monitor the actual interconnection function between the male and female parts.

Only when an appropriate connection has taken place can a clear signal for full activity in the means of control and / or monitoring of the means of transport be obtained. This ready signal is indicated in Figure 6 by il. The module or node 201 is an identification module. Only when the mutually interconnectable parts 231a and 231b of the module or node 2 assume an interconnected position can the system receive start or initiation for activity or commissioning. Said parts 231a and 231b are shown in figure 6 in disassembled condition. The parts are equipped with a jacking function with pins and sleeves in a manner known per se. The part 231a can cooperate with different parts 231b which are assigned to different persons who are to have access to the means of subsistence in question. Said identification or identifications are in Figure 6 represented by i2.

Alternatives to the current guide or current waveguides can take place in another manner known per se. So Lex. the unpacking and unpacking procedure can be used. Alternatively, the suspension function can be used, whereby the unit is suspended in hinges or guide elements which, depending on manual influences, can be opened and closed.

The unit 207 can be switched on after disconnection according to the above. Alternatively, a basically new or modified second unit with substantially the same design can be connected instead of the first-mentioned first unit. Alternatively, the second unit may be a supplemented or modified variant with respect to the first, second and / or third components listed above, which may be relevant when changing the other components of the means of propulsion (eg new engine (-your)),. Alternatively, you may want to change the control and / or monitoring system or be able to coordinate this with further, e.g. systems of another type.

Digital signals established on the connection between the modules or the nodes are indicated in Figure 6 by i3. In its disengaged position, the unit will prevent all forms of theft of the means of transport and / or its components in a very prominent manner. The detachable unit can be designed with light design technology for easy portability, by which is meant that the unit has an external shape which is easy to remove and connect and carry, respectively. The unit is preferably arranged with low weight, e.g. with a weight selected in the range 1-5 kg. With regard to the sealing functions between the waveguides and the waveguide parts when connecting and disconnecting, reference is made to e.g. to the Swedish patent applications listed above. The locking part works as above with the capercaillie force in the spring 221 which locks the male and female parts to each other in the coupled position. The locking part can be opened against the action of said spring and / or in combination with rotational movements around the center line of the locking part (coincides with the male and female parts according to figure 6).

When disengaging the parts, ie. when the unit is disconnected, the action against the action of the spring force takes place so that the units 207 and 219 can be separated from each other. In Figure 6, a means of supply is symbolically indicated by 237, which means of means can be of the type specified in the above and in the said Swedish patent applications. The control panel and instrument functions may include speed and length measurement functions, _ control functions, etc.

The invention is not limited to the embodiment shown above as an example, but can be subjected to modifications within the scope of the appended claims and the inventive concept. So e.g. the unit can be interchangeable with another unit arranged in with the same or different parameters. Externally, the respective second unit corresponds to the first unit (to the outer dimensions). It can also be emphasized that connection inputs and connection sockets to or on the waveguide or waveguides take place according to known principles (eg in the way that has happened in the Swedish applications. This also applies to the joint arrangement between the waveguides. (for reasons of clarity). oqeoan .nu an. a. nun no ou om oauao nu noucnqy.. 8 coun .u an: nu a. un .. a
