Description

Digital remote identification system of vehicles.

Object of the invention

The present invention relates to a system which has been specially designed to identify distance to vehicles fully automated, in order to register their positioning, speed, etc., as well as to notify them of possible incidents.

The invention thus falls within the scope of the vehicles, both land and sea.

Background of the invention

In the practical scope of the invention, the only known vehicle identification system it is the one based on the "toll system", consisting of a series of devices used to pay the amount of circulation on a highway, so that the vehicle, equipped with a radio frequency emitting device, when passing through an arc detector, is detected by the system, which loads fully automatic to the account assigned to said vehicle on amount in question, when recognizing and discriminating the signal received, so that it does not have to stand at that toll, with the consequent and negative impact at the level of loss of waiting time and queues that implies.

Without good, these types of devices comply satisfactorily the function for which they have been planned, they are expensive, by incorporating location technology by Satellite or communications via GMS, GPRS, have a high electricity consumption, these are bulky devices, and Above all, they are not designed to control the vehicle positioning along a certain network, receive messages from the authorities, and other functions that will become apparent throughout this description.

Description of the invention

The digital remote identification system that the invention proposes resolves in a fully satisfactory manner the problem previously exposed, allowing to control in All time positioning, speed, and other data of the vehicles that are within the network covered by the system, as well as notify them of possible incidents.

For this, in the system of the invention Three types of devices participate:

-

A coordinating device, which is responsible for controlling all the system, will have a graphical interface that will allow access to the information collected by the system through the different terminals, counting on it with a communications module based on low frequency radio frequency (ZigBee).

-

Terminal devices; installed in Each vehicle is limited to storing and transmitting data, through of a low frequency radiofrequency communications module Consumption (ZigBee) with programmable microcontroller integrated.

Through said communications module, said device may send a signal for its location and identification by a beacon, and consequently of the coordinating device, as well as receiving information, which will be displayed through a screen. The communication will be established automatically with the coordinator if there are no intermediate beacons.

-

Beacon Devices: Arranged on a series of signaling arcs distributed throughout the network covering the system, allow to receive signals from the vehicles through a communications module based on low consumption radio frequency (ZigBee) with microcontroller integrated programmable, as well as send them data, process that will remain registered in the coordinating device, with which they will communicate through the rest of beacon devices, by forming a network of nodes close enough to each other to be able to communicate with each other and act as transmission elements of data in both directions with respect to the device coordinator.

The three devices can be both mobile as fixed.

The system will also serve to warn the drivers through the sending of the corresponding signal, of that approximate an area where there has been a incident, such as a lane cut, an accident, presence of fog banks, etc., information that will be displayed in the terminal automatically when passing through the corresponding beacon.

In the same way the terminal device may send information to other vehicles with the terminal in case of accident, alerts or SOS, to beacons or coordinators.

These media can serve also so that traffic agents can communicate directly with a vehicle when they deem it convenient.

The system thus described, allows to carry out a totally wireless communication, avoiding faces and expensive cable underground installations, with sizes of reduced devices, as well as their electricity consumption, with a range between devices of the order of 4 kilometers, 65,000 nodes can be integrated into each network, which may work according to the different network topologies, point to point, star or mesh, with a data transmission of 250 Kbps.

However, the system of the invention may combine with other technologies, such as GPS, GPRS, etc., being compatible with all types of sensors, presenting, being equally applicable as a measure of remote management and remote control.

Description of the drawings

Preferred Embodiment of the Invention

In view of the figures outlined you can it should be noted that at least one coordinating device, as shown in figure 1, which communicates with a plurality of beacon devices, as shown in figure 3, which form a network, distanced from each other a sufficient magnitude to allow wireless communication between them, so that each vehicle is assigned a terminal as shown in figure 2, which is detected upon entering of the coverage of each beacon, being able to establish a bidirectional communication between all the devices that They participate in the system.

More specifically, and as you can observe in figure 2, the terminal device will incorporate a internal memory (1) in which the vehicle data will be stored, such as registration, owner, insurance information, date of the ITV, etc, internal memory that will be integrated in a communications module based on low consumption radio frequency (ZigBee) (2), equipped with a microcontroller (3), to which the corresponding antenna (4) with hose, device that will have of its own encapsulation (5), with a source of supply (6), in which a voltage regulator (7) is established and an input filter (8).

The aforementioned microcontroller, assisted by the corresponding software, you can incorporate a screen (9), so as another series of sensors (10), in case these were necessary.

Through the antenna, the terminal is identified at every step for each beacon, while across the screen messages received by the Authority may be displayed in question or the beacon device.

As can be seen in Figure 1, the coordinating device is constituted from a module of Communications based on low frequency radio frequency (ZigBee) (11), associated with a microcontroller (12), equipped with a memory (13), and the corresponding antenna (14) with hose, being able to incorporate the corresponding sensor (18), element assisted to same as in the case of the terminal by a power supply (15) equipped with an input filter (16) and the corresponding one voltage regulator (17), with the particularity that it incorporates a integrated system (19) with a microprocessor (20), and a system embedded operation (21), assisted by the corresponding memory (22), to which at least one display (23) and a keyboard are associated (24).

As previously mentioned, this device will allow to write and send messages, allowing inform other vehicles of unforeseen situations or dangerous as well as arrest warrants.

The coordinating device will communicate with the vehicles through the network of beacon devices, such as the shown in figure 3, which are constituted from a low frequency radio frequency communications module consumption (ZigBee) (25), equipped with a microcontroller (26), with its corresponding internal memory (27), and its communications antenna (28), being able to incorporate additional sensor (29), all this electrically powered through a power supply (30), in which an input filter (31) and a voltage regulator (32).

While the beacons must be located some close enough to others to be within its margin of coverage, these can be used to narrow and control large spaces without having to cover all your surface with said beacons, but simply the perimeter of the same, so that both the input and output of any vehicle on that surface.

This application can be of great interest in the naval field, although it is equally applicable in the field land.

It is noteworthy that the terminal devices may be under beacon areas and small size coordinator by the way, like the case of a ship. In this case the device terminal will be carried by the people on the boat with what Get to know if someone has fallen into the water quickly. In case of definitive loss of that person will be able to determine their position if any beacon device or coordinator is placed to sufficient distance to enter coverage, approximately 4 km in the open sea.

Finally, it should be noted that the system could be equally applicable in events such as races, rallies or similar, long-distance, in which a series is established of points to go through, after passing through the goal, in order to allow the passage of vehicles through the different control points, as well as quickly detect possible deviations from them.
