Description

ELECTRONIC DEVICE AND OPERATION METHOD THEREOF The present invention relates to an electronic device and an operation method thereof, more in particular the invention related to an electronic device and method for updating a navigation system of a ship.
Ships rely heavily on digital nautical navigation systems such as ECDIS. These navigation systems are essential in planning and safely performing voyages. When navigation data on the navigation system is not up to date, ships are at significant risk of grounding or collisions. All ships are therefore mandated to update their navigation system frequently, often on a daily basis.
Updates of the navigation system can often be obtained via CD, DVD and/or internet downloads.
Traditionally, type approved navigation systems on ships (ECDIS or RADAR) have been stand-alone, or connected by network only to the other bridge equipment. Direct internet connections to navigation systems have been discouraged because of security concerns, as navigation systems are vital to the safety of the ship, corruption or hacking of the navigation system can cause severe problems. Navigation systems are therefore often updated by loading updates on a portable storage device, such as a USB-stick, from a computer that is connected to a network or that is capable of reading CDs and/or DVDs, and transfer the portable storage device physically to the navigation system in order to perform the update. A disadvantage of this approach is that the portable storage device might get infected by a computer virus which might corrupt the navigation system. Another disadvantage is that this way of updating the navigation system involves many steps that have to be carried out manually. This is especially the case given the frequency at which updates are required.
The present invention aims to obviate or at least significantly reduce the aforementioned problems by providing an electronic communication device and method to act as a gateway device between a navigation system of a ship and a chart update service.
To that end, the invention provides an electronic device comprising: — a first communication interface comprises at least one wireless interfaces and/or at least one wired interface and configured to connect to a chart update service; — asecond communication interface comprises at least one wireless interfaces and/or at least one wired interface and configured to connect to a navigation system; — a memory module comprising a chart information section; — at least one processor; — a memory accessibility switch to control a connection to the chart information section, wherein the memory accessibility switch is switchable between:
— a first connection state allowing information transfer between the chart update service and the chart information section via the first communication interface and the memory accessibility switch; and — 4 second connection allowing information transfer between the navigation system and the chart information section via the second communication interface and the memory accessibility switch; — an activity sensor electronically connected to the processor and to the memory and configured to measure an activity on the chart information section; and, wherein the processor is configured to obtain activity data from the activity sensor and to control the memory accessibility switch to switch between the first connection state and second connection state based on the activity data. It is noted that the activity data may comprise reading activity and/or writing activity on the memory. By having an electronic device comprising an activity sensor and memory accessibility switch it is possible to alternately provide the chart update service and the navigation system with access to the chart information section of the memory. An advantage of this is that it enables a user to update the navigation system without having to switch a USB storage device between a computer and the navigation system. This prevents the USB storage device from getting corrupted by, for example, a virus, making the navigation system safer from being hacked or infected by a virus.
Another advantage is that the electronic device according to the invention enables the user to update the navigation system more easily, since fewer manual steps are involved.
Another advantage is that by having an activity sensor, it is possible to alternate between providing access to the navigation system and to providing access to the chart update service without the possibility of having concurrency problems caused by both having access to the chart information section at the same time.
It is noted that the writing activity and/or reading activity might refer to activity of the processor of the electronic device, the chart update service, the navigation system and/or other processes, systems or elements which may access the memory.
In an embodiment of the invention the processor is configured to: — determine an inactivity period based on the activity data wherein the activity sensor does not measure any activity; and — only control the memory accessibility switch to switch during a determined inactivity period of a duration that is longer or equal to a predetermined memory inactivity threshold.
It is noted that controlling the memory accessibility switch to switch may comprise controlling the accessibility switch to switch from the first connection state to the second connection state or vice versa depending on a current connection state.
An advantage of this embodiment is that the memory accessibility switch is only controlled after a period of inactivity; making is less likely that a writing of reading activity of the navigation system or the chart update service is interrupted.
In a further embodiment of the invention the predetermined memory inactivity thresholds is between 1 second and 300 seconds, preferably between 5 seconds and 30 seconds.
It is noted that the inactivity period is reset after control of the memory accessibility switch, This means that, for example, when both a connected chart information service and connected navigation system do not cause any activity when, for example, no new data available, the processor will control the memory accessibility switch to alternate between the first connection state and the second connection state until there is new activity.
In an embodiment of the invention the predetermined memory inactivity threshold is based on at least one of: a number of files stored on the chart information section, an age of the files stored on the chart information section, a size of one or more files stored on the chart information section, a number of iterations of inactivity periods.
It is noted that the predetermined memory inactivity threshold may be adapted by the processor in reaction to a change in at least one of the number of files stored on the chart information section, the age of the files stored on the chart information section, the size of one or more files stored on the chart information section, the number of iterations of inactivity periods.
An advantage of basing the predetermined memory inactivity threshold on the above mentioned factors is that it is less likely that the memory accessibility switch is controlled prematurely.
In an embodiment of the invention the chart information section comprises a dedicated chart service section and a dedicated navigation system section, and wherein a connection that is available in the first connection state is a first connection and comprises a connection to the dedicated chart service section of the chart information section and wherein a connection that is available in the second connection state is a second connection and comprises a connection to the dedicated navigation system section of the chart information section and wherein the dedicated chart service section is not accessible through the second connection and wherein the dedicated navigation section is not accessible through the first connection.
In a further embodiment the memory accessibility switch has a third connection state wherein the first connection and second connection are both available and a fourth connection state in which neither the first connection and the second connection are available and wherein the processor is configured to control the memory accessibility switch to switch to the third connection state after the period of inactivity and is further configured to, when the activity data comprising writing activity to the dedicated chart service section and/or the dedicated navigation system section, perform the following actions: — switch to the fourth connection state; — mirror the content of the dedicated chart section and the dedicated navigation system; — switch to the third connection state.
In an embodiment of the invention the processor is configured to establish a rest state based on an occurrence of a predetermined number of consecutive inactivity periods, wherein the processor is configured to, after establishing the rest state, control the memory accessibility switch to switch to the second connection state and to no longer determine the inactivity period while in the rest state, and wherein the processor is configured to terminate the rest state on the basis of the activity data comprising reading and/or writing data, wherein terminating the rest state comprises determining the inactivity period.
It is noted that the predetermined number of consecutive inactivity periods may comprise one or more consecutive inactivity periods.
An advantage of this embodiment is that the memory accessibility switch does not switch continuously between the first connection state and the second connection state during a longer period of no memory activity. This is especially advantageous when, for example, the user of the navigation device gets a notification from the navigation device if a new peripheral is connected, since switching to the second connection state may be perceived by the navigation system as a storage device being connected.
In a further embodiment of the invention the processor is further configured to terminate the rest state based on a switch request of the chart update service.
An advantage of this embodiment is that the chart update service can easily terminate the rest state when, for example, new chart update data is available.
In a further embodiment of the invention the switch request comprises an API request or a writing activity to the memory.

An advantage of this embodiment is that new files added to the chart information section are scanned by a virus scanner before being made accessible to the navigation system, lowering the IO changes of the navigation system getting corrupted by a virus.
In an embodiment of the memory module comprises connection information data that enables the first communication interface to connect to the chart update service, preferably using a secured protocol, the secured protocol more preferably comprising a SSH connection or a VPN connection.
An advantage of this embodiment is that the electronic device can automatically connect to the chart update service.
In an embodiment of the invention the connection information data enables the first communication interface to communicate with the chart update service using a secured communication protocol.
