What makes it a new element for the state of the art capable of solving the problems of the technical area mentioned above.

TECHNICAL STATUS

[023] There are some devices similar to the proposed invention, presented in some patent documents that have exactly the same installation concept, as proposed here, as a standard circular connector that is present in various types of commercial vehicles and heavy machinery, however these devices have some deficiencies and disadvantages in relation to the approach proposed by the present invention, the main one being the concept of telematics, that is, the ability to read and write data in the electronic control units of the machine. Among these devices can be mentioned those described in the following patent documents:

[024] Patent document US2014011483, VEHICLE BUS ACCESS POINT SYSTEM AND METHOD, which describes a system and method of transmitting vehicle information from a vehicle to a server over an external network.

[025] A vehicle bus connector module is connected to a vehicle bus via the vehicle's vehicle bus connector. The vehicle bus connector module is also communicatively connected to a personal communication device. Vehicle information is collected from the vehicle's bus and combined with the information captured by the personal communication device to form a driver record. The driver log is transmitted to the server via the external network;

[026] Patent document US2009102626, SYSTEM APPARATUS AND METHODS FOR DATA COMMUNICATION BETWEEN VEHICLE AND REMOTE DATA COMMUNICATION TERMINAL, BETWEEN PORTIONS OF VEHICLE AND OTHER PORTIONS OF VEHICLE, BETWEEN TWO OR MORE VEHICLES, AND BETWEEN NETWORKS, AND BETWEEN system, apparatus and methods are provided for data communications associated with a vehicle. The apparatus preferably includes at least one electronic subsystem associated with the vehicle and a plurality of electrical conductors connected to at least one electronic subsystem and associated with the vehicle. A vehicle data communication protocol converter is preferably connected to the plurality of electrical conductors to convert a first data communication protocol associated with data communication over the plurality of electrical conductors to a second data communication protocol, such as an infrared, RF data, Internet, or other network communication protocol. The apparatus preferably also includes a transceiver connected to the data communication protocol converter to transmit the vehicle's second data communication protocol and receive the data communication protocol from another part of the vehicle, a remote data communication terminal. data, another vehicle or other communications network;

[027] The patent document US2004137768, REMOTE DIAGNOSTIC UNIT ENCLOSURE ASSEMBLY, where an electrical connector with a removable printed circuit board is disclosed. The printed circuit board is capable of electrical connection with pins that extend through a connector body and a spacer and is capable of electrical connection with conductive wires. The printed circuit board has key elements to ensure proper alignment with the pins. A lens piece cooperates with the printed circuit board to allow visibility of at least one light emitting diode on the printed circuit board. The lens part, the printed circuit board and the spacer are held in place by a collar attached to the connector body;

[028] Patent document US2005010341, REMOTE DIAGNOSTICS DEVICE (RDU), which describes a remote diagnostic unit for use in a heavy vehicle includes a pin connector that communicates with a data bus in the vehicle. The pin connector receives a signal from the data bus. A microcontroller receives and interprets a standard diagnostic message as a function of the signal received by the pin connector. A plurality of lights are controlled by the microcontroller according to the standard diagnostic message; and

[029] Patent document WO2016187386 (US2017202044, US2016344859, BR 11 2017 024503 5), PROTECTIVE CONNECTOR AND APPLICATIONS THEREOF, which describes a protective connector includes a central mounting structure, coupling pins and a coupling coupling structure. The core assembly structure has circuits mounted on it. The corresponding coupling structure substantially surrounds the core mounting structure and joins with another connector, so that the corresponding pins of the protective connector are electrically coupled to the pins of the other connector. The corresponding coupling structure is mechanically free in relation to the core assembly structure, so that the forces applied to the corresponding coupling structure to couple the protective connector to the other connector are not applied to the circuits within the core assembly structure.

[030] All the mentioned patent documents present devices capable of only reading the operating data and making the telemetry for the remote system which can be different in each application. None of the similar inventions presented in these patent documents is capable of writing data in the referred units, that is, applying remote control techniques to effectively change the operational behavior of the machine, such as, engine shutdown or start, increase or decrease gait or acceleration, among others.

[031] The fundamental difference is the fact that the state of the art presented by these similar inventions necessarily requires an external peripheral device to communicate with the cellular network to send data from the machine or vehicle to the world wide web. In the proposed invention, the use of these devices is optional, as its internal electronic board is innovative in integrating all electronic components and internal antennas for communication that exist in portable devices, such as: cell phones, tablets and the like.

[032] Another important innovation is the integration, within the telematics device itself, of special receivers and antennas tuned with the satellites of the global navigation system that are part of the external devices necessary for the complete operation of similar devices presented in other patents.

[033] In addition to the automatic synchronization of the internal clock with the world time, the reception of satellite signals allows the accurate calculation of the speed, altitude and geographical position of the machine in real time. In addition, all similar electronic devices presented in other patent documents still have the deficiency of not sensing the various axes of angular movements that cannot be detected by the satellite positioning system, such as: tilt, rotation and azimuth.

[034] Another major disadvantage of the state of the art presented in other patent documents is the lack of signal control interfaces for reading sensors and actuator control present on the machine, as well as the lack of direct communication with the badge or medium. similar operator identification.

[035] The last important innovation is the mechanical solution that allows the opening of the device to access its interior without the characteristics of resistance against the ingress of dust or liquids, allowing the user to change the cellular operator's subscriber card and the expandable memory card, non-existent in the state of the art of the mentioned patents.

[036] This data plan exchange between operators can also be carried out without changing the card, that is, through a configuration carried out remotely, through another innovation integrated with the electronic card telematics device.

MOTIVATION

[037] The precise definition of the technical terms used in the title of this patent is fundamental to justify the innovative concept of the present invention. Thus, it should be clarified that heavy motorized machines for off-road operations are different from light and commercial vehicles such as cars, trucks, buses and utilities for use on regulated roads and roads. Machines are designed to perform a certain operation in areas where the use of nameplates for traffic on public roads is not normally regulated, such as tractors, excavators, forklifts, motor graders, loaders, harvesters and the like that are operated by specially trained people. trained.

[038] In addition to being important for the operation of the machine itself, the data and information of these activities can be monitored to determine the performance of the work performed, fuel consumption and other specific inputs, in addition to alarms and other information that are important to to avoid failures, breaks or unplanned stops of these machines.

[039] In order to clarify one of the main innovations of the present device, it is important to emphasize that Telematics is a well-defined term and of public knowledge, which can be divided into two complementary fields or terms normally used to designate devices that may have the function of interface with machines for remote communication, as follows: Telemetry, which refers to applications for reading or measuring information at a distance, that is, the data flow follows from the machine to a remote system; and the Remote Control, which refers to applications of writing or commanding information at a distance, that is, the data flow follows from a remote system to the machine.

[040] Remote System is any computer equipment that has the function of storing and processing information received or sent to the machine, and can be classified into three types: the fixed system, which is the most common type of system processing where data is computed by networked servers that are normally within reach of users who can still access information on their normal or portable computers; the mobile system, which is performed by personal devices with portable operating systems such as cell phones, tablets, watches and the like, where it is possible that the processed information is available to the user with mobility in any location, including near the machine itself if the technology of wireless connectivity has the range; and the cloud system, which is the most recent processing approach where the entire server infrastructure can be distributed in several geographic locations, with the possibility of access by the user in any terminal with access to the world wide web.

[041] Although this whole concept of telematics of machines for communication with remote systems is public knowledge, there are substantial innovations in how these concepts can be applied in practice through the invention presented here, which is based on a design of a specific device to withstand the machine operating environment, which is more demanding than vehicle environments.

With a maximum weight of 102 grams, it has 60 mm in diameter and 50 mm in length and can be opened by means of fixing elements such as screws and or locking pins, to access its interior to exchange removable cards.

[078] The electronic boards, main and secondary, work together to program both the reading and the writing of data from electronic control units for engine, transmission and others that are loaded on motorized machines intended for off-road operation.

[079] The operation of the telematics device is only possible through several blocks of digital and analog electronic circuits, responsible for the energy management of the boards, data interfaces with the machine network, data processing and storage, as well as control of the data. signal from internal antennas tuned to various frequencies for communication using different wireless communication technologies.

[080] The electronic part of the telematics device consists of the Secondary Board (4), with three functional circuit blocks, and the Main Board (3), which has a total of six functional blocks responsible for the processing, storage and communication functions without wire of the data processed by the device, according to the block diagram shown in Figure 3.

[081] The Secondary Plate is responsible for the three blocks that interface with the machine through the Integrated Connector (20) which has nine pins in all identified by the letters A to J in alphabetical order. Each pin is responsible for a corresponding electrical connection on the standard complementary connector SAE-J1939 / 17 located on the machine that can supply voltage levels between 6 and 36V on 2 of its pins for the Power Supply (11) that manages the energy of all the signs. The integrated Connector (20) has seven connection pins with several electronic modules that are embedded in the machine to control the engine, transmission, cabin and others. It is these pins that connect and communicate with the Data Interface (12) that has the function of decoding the electrical signal levels and communication rates of the RS232, KLINE and CAN data protocols.

[082] The Data Interface (12) works in conjunction with the Control Interface (13) which connects to the same connector pins and can be activated when there is no data communication to alternatively read voltage levels up to 36V from different sensors that may be present on the machine, such as temperature, pressure, fuel level and others, whose reading values of information may be necessary to trigger actions to activate current outputs up to 1.5A necessary to supply the signal control of the machine's actuators, such as solenoids, valves, sounders and others.

[083] The Card Interface (14) is responsible for the standard removable MicroSD memory card, which allows the device to have its data capacity expanded by the user. This interface has another connection for a removable card size 4FF or Nano SIM (Subscriber Identification Module) for signing the standard cellular data plan and function for controlling access to cellular networks. This block of the Card Interface (14) manages the writing and reading of all the data that are analyzed and manipulated by the Processing Cores (15) that form the main block responsible for the telematics intelligence necessary for data reading and writing operations. in the machine's electronic control units. This block of the Processing Cores (15) is controlled by programming codes stored in its memory that implement algorithms developed especially to apply remote control techniques to effectively give command instructions to the operator or even automatically change the machine's operational behavior, such as example, engine shutdown or start, gear up or down or acceleration, among others.

[084] Motion Sensors (16) are circuits dedicated to measuring up to nine axes of linear and angular displacements, three of acceleration (m / s2), three of angle (rad / s) and three of magnetic fields (mT). The processing of all these readings allows, through mathematical calculations, to infer the slope of the terrain through which the machine travels to alert the user to risks of tipping and excessive vibrations, for example. Another important function of this block of Motion Sensors (16) is to increase the accuracy of the location coordinates decoded by the Satellite Receiver (19) with the ability to simultaneously tune up to sixteen satellite signals from the American (GPS), Russian (GLONASS) and Chinese (BEIDOU), so that the device automatically synchronizes with the world time and calendar and makes real-time calculations of the distance traveled, travel speed, altitude and geographical position of the machine.

[085] The Cellular Modem (17) integrates all electronic components that manage the two-way communication of the telematics device with the base stations of networks with 2G and 4G coverage signal from cellular operators. This Cellular Modem block (17) works in conjunction with Radio Transceivers (18) to use the Internal Antennas (20) that tune various communication frequencies to expand the even more possibility of connectivity to standard 802.11 b Wi-Fi home networks / g / n and LoRa standard 802.15.4. This interaction between these two blocks of the Cellular Modem (17) and Radio Transceivers (18) and the antennas that allow the best wireless communication technology and frequency to be selected automatically according to the demand for data rate and the availability of coverage by the region of operation of the machine, so that it is connected to the world wide web as much as possible without the need for an external peripheral device such as cell phones, tablets and the like.

[086] The main objective of the invention is to be a flexible telematics solution, that is, compatible with various types of motorized machines for off-road use, and complete, that is, that does not depend on external peripherals such as portable devices or the like for communication with a remote system as previously defined.

[087] For this to be possible, the invention has a robust mechanical concept, due to the demanding operational environment of operation, subject to high vibrations and bumps, extremes of temperature and humidity, in addition to weather and other corrosive liquids.

[088] In addition, the internal electronic boards have a high tolerance for electrical surges and anomalies common in the machine's power generation system, as well as immunity to electromagnetic radiation from other radio frequency equipment present inside the cabin.

[089] An important advantage is the presentation to the operator of a graphical interface with buttons where in addition to entering data manually presented on the original screen of the on-board computer embedded in the machine where information created by the telematics device can be viewed. Other solutions are based on the interface presented on the portable device handled by the operator, which obviously can take away your attention and is therefore not recommended for safety reasons inside heavy machines in operation.

[090] Another benefit of innovation is the integration of input and output interfaces to the device with programming of different voltage and current levels for reading sensors and controlling actuators.

[091] This innovation allows security actions, such as, for example, the measurement of external signs of locking the cabin door or weight detection on the operator's seat, which are reported to the remote data processing system. In this case, a remote control can be sent so that the machine's engine is turned off, or even for the device to activate its output interface connected to the machine's horn or light siren to alert the operator or other people who are close to the machine that there is a situation of imminent danger.

[092] The motion sensors are a great advance in relation to similar devices, as they have the important function of alerting about the imminent danger of tipping the machine when operating on sloping terrain, being still of fundamental importance for those that operate with stops. cab rotating around the operating platform, making it possible to measure the performance of the work performed by the operator

[093] The wireless interface with the badge or similar means of identification of the operator has the advantage of recording your work shift directly on the telematics device that can, in addition, control the automatic start of the machine in case the remote system authorizes it. established rules of schedule permissions or individual authorization to operate each type of machine.

[094] Unlike other similar solutions that have the problem of losing new data, or discarding old ones when there is no more memory space, the device has the advantage of internally storing operating data in its expandable memory, something essential in the lack of coverage of a data network that increases the demand for memory space depending on the time without connectivity.

[095] Thus, due to the characteristics of configuration and operation, described above, it can be clearly noted that the TELEMATICS DEVICE FOR MOTORIZED MACHINES FOR OFF-ROAD OPERATIONS, it is a new device for the State of the Art which it covers. of unprecedented conditions of innovation, inventive act and industrialization, which merit the Utility Model Patent Privilege.
