Abstract

The invention relates to an electronic security seal with geolocation capabilities, which is integrated, programmed and monitored by means of a web platform. The electronic security seal of the invention is characterised in that it comprises a single case that is installed on goods containers or other freight and transportation means, said security seal being secured or anchored to the gasket on the doors of the container, such that it fits to the rubber forming the gasket by means of a groove provided on the rear of the case and, with the aid of neodymium magnets, is solidly attached and ensures that the two doors are closed, along with the activation of two ferrous metal inductive sensors that continuously monitor the contact with the metal surface of the doors of the container on which it is installed and controlled via a resonant circuit. The electronic security seal with geolocation capabilities is integrated into a computer platform or geolocation software program, for the programming, monitoring and management of the different alarms that the security seal registers during the transportation of the container or freight, including an alarm associated with the security seal being opened while the container or freight is being transported, such that if the electronic security seal is removed from the container or in the event of an attempted breach outside the authorised programmed destination geo-fence, this event will be registered as an unauthorised opening and transmitted in real time via GPRS-GSM communications to the computer platform, which will, in turn, communicate said information, also in real time, both to the monitoring centre and also to the pre-determined e-mails and to mobile devices authorised for this purpose, such as smartphones, tablets or laptops.

Description

GEOLOCALIZADOR ELECTRONIC SEAL OF A SINGLE RECEPTACLE WITH PROGRAMMING SOFTWARE, MONITORING AND MANAGEMENT OF ALARMS FOR CONTAINERS AND OTHER MEANS OF

CARGO AND TRANSPORTATION

TECHNICAL FIELD OF THE INVENTION The present invention belongs to the field of manufacturing and development of hardware equipment integrated in its corresponding software, focused on electronic security for freight and freight transport units, generally maritime containers of merchandise, by placing the same mobile security devices, called "Electronic Precinct", which in turn are integrated into a computer platform or geolocation software that, using GPS technology in combination with various telecommunications systems (GPRS, GSM) allow us to monitor, control and ensure in real time, the cargo and transport units of goods, whether they are en route or travel, or if they remain deposited in specific places for temporary custody and control (ports, free zones, warehouses, etc.).

BACKGROUND OF THE INVENTION The invention specifically relates to the electronic seal for containers and other cargo and transport units, as well as to the software or computer platform in which said seal is integrated, and which together provide us with the traceability and security of the load unit Basically, the electronic seals, once placed on the bars of the container door, transmit the position and status of their sensors to the computer platform and the latter is responsible for managing the information, treating it specifically to transmit, by some means known, if there is an unauthorized opening or withdrawal of the electronic seal (among others configurable alarms in the system). For this reason, the electronic seal has become a tool to fight organized crime for theft or assault of merchandise containers, theft or ant theft, smuggling, tax fraud, and drug contamination of transported merchandise. .

The present invention is applicable to maritime containers of merchandise fundamentally, due to its greater volume of presence in the international market as a unit for loading and transporting merchandise; but equally versatile and applicable to other cargo and transport units other than the container (trucks, vans, toned containers, spider or vehicle loading platforms, container-carrying platforms, etc.).

Various types of electronic container seals that are operating in the market are known in the current art.

All of the inventions known to date in the technology of electronic seals for containers, have a common factor or base: they are electronic devices that are complemented with other components or modules external to the main body or receptacle, to be able to hold or anchor it in the opening bars of the container door; In addition to the type of fastening or anchoring to the bars, they require some type of closing and opening mechanism once they have been placed in said bars, in order to detect if there is any attempt of violation or unauthorized opening of the container.

In any of the technologies known at present, to the electronic device itself, all kinds of gadgets or assemblies are attached, such as hook-jaws, shafts with internal pinions, bolts, clamps, brackets, perforations, welds, screws, nuts, bushings, lathes, bars, etc .; thus becoming outgoing mechanical components of the electronic device itself or main body; said components necessary for the placement or anchoring of the main electronic device require, in any case, to carry out their placement on the bars of the container, of common tools or specialized tools of manual action, keys, insurance, pins, picks, etc .; in some cases, and in other cases they require an automated communication system via telematics, gprs, gsm, alphanumeric keypad, wireless commands, etc. to automatically activate the lock or locking system in question. The latter wireless systems have the great disadvantage that if there is a lack or failure of wireless communications, or a power failure in the device itself, it will not be possible to close or open the electronic seal, or therefore proceed to anchoring or unpinning of it. All these anchoring systems and closing / opening systems have the following drawbacks in the known technique:

1. Lack of versatility: currently known electronic seals only serve closed containers or cargo or transport units, and that necessarily have vertical bars for opening and closing the door or doors, since otherwise they have no possibility of be anchored or attached, for example, to freight transport units with doors without bars, flat doors, trucks with curtain doors, enloned or top-loading containers, swing doors, etc. 2. Vulnerability to unauthorized opening attempts or sabotage: being condemned to be anchored or attached to the door bars, the vulnerability of the opening / closing system and the consequent alarm that the electronic seal may issue, depends one hundred percent in turn, the level of vulnerability of the bars themselves and even the door itself.

What happens in practice is that the current electronic seals are subject to violation and violation of their security system, by sabotage of the door bars; since said bars are normally screwed to the container door itself with several anchor points. That is to say, what is happening is that the organized bands do what they do is disassemble the bars of the door of the container where the electronic seal is anchored, and remove these bars together with the anchored seal, a reason why the systems opening / closing and subsequent alarms of the device do not trigger, because it is still anchored to the bars; in this way, once the bars are removed together with the seal, they can proceed to open the doors of the container and commit the illicit in question, with the certainty that the security system of the device has not been triggered.

The same situation of vulnerability happens when instead of unscrewing and disassembling the bars completely from the door of the container, what they do is cut the bars at the top and bottom of where the electronic seal is placed and extract that part cut into a single piece together with the seal still anchored to said bars.

3. False opening or sabotage alarms: the known systems already described, use mechanical systems for the detection of attempted violation or sabotage, such as pushbuttons, switches, relays; In most cases; being mechanical components that depend on electrical or electromagnetic impulses, or a direct physical force or pressure that keeps them in contact with the bars of the door, so that when that impulse, force or pressure is removed when disassembling them and in that case send the unauthorized opening alarm to the monitoring computer platform, what happens in practice is that these same security mechanisms generate false alarms when the load or transport unit travels on roads or roads in poor condition, with potholes, holes, estiva or unloading of the container, etc. ; In these cases, the electronic seal interprets the blow or shock caused, as an attempt to open or violate the equipment by decreasing the pressure or force on its closing / opening sensor, causing a constant uncertainty as to whether they are actual events of violation of the electronic seal during the monitoring of the load units or if it is only due to shocks or shocks. Examples with similar technologies are found in patent documents:

PCT / IB2014 / 002756 Francisco Javier Diossa Arango. "Remote controlled terrestrial satellite electromechanical lock for cargo containers".

Therefore, there are to date a series of needs and technologies not covered by current electronic seals, which can offer us effective security and control measures to ensure the inviolability and integrity of goods transported in containers and other transport units loading solving the problems and inconveniences already mentioned.

We achieve these objectives with the development and manufacture of our geolocation electronic seal, together with the development and implementation of the corresponding software or computer platform where the electronic seal is integrated, to manage and monitor its traceability, as well as alarms and warnings. generated on the routes or trips of the goods or transport units.

DESCRIPTION OF THE INVENTION The object of the present invention, the electronic seal, consists of a unique equipment constructed in injected polyamide shell PA6 reinforced with Fiberglass, (Figure 6) houses inside a GPS module (Figure 6, item 13), a control and communication module via Wifi (Figure 6, point 15), a connection module (Figure 6, point 14) and inductive sensors for alarm detection (Figure 6, points (2A and 2B); via Neodymium magnets included in the base of the equipment (Figure 6, points 1A to 1 H), will be temporarily fixed and installed in the merchandise containers, so that it can detect its opening (by means of two ferrous metal inductive sensors that any of them acts redundantly in case of an attempted rape or sabotage); through the electronic device that provides the functions of geolocation, transmission, data storage, and alarm detection, this s will be transmitted in real time via GPRS to a server center (Figure 5), which, in turn, will forward them to the monitoring computer platform and to the emails that are defined.

The equipment consists of two Technologies for the detection of opening or sabotage: Security 1:

The electronic seal implements an automatic ferrous metal detection process using two inductive sensors (Figure 1, points 2A and 2B).

This type of sensor (Figure 4) is characterized by the design of an internal circuit and a transistor that is used to generate the output voltage with detection. In this case the selected type is an NPN that generates an OV output.

For the selection of the NPN transistor type, both the theoretical specifications of NPN and PNP type sensors, as well as laboratory tests were considered, reaching the final conclusion that the NPN type is faster in switching since it works with reference OV On the contrary it has less noise immunity, less voltage drop.

Thus, the detection of metal by sensors as alarm generators for control systems is indispensable. Compared to mechanical switches, they offer virtually ideal conditions: contactless and wear-free operation, in addition to high switching frequencies and switching accuracy. Together they are resistant to vibrations, dust and moisture. Operation of inductive detectors:

The inductive detectors (Figure 1, points 2A and 2B) implemented in the device use the physical effect of the resonant circuit factor change that originates from eddy current losses in conductive materials. An LC resonant circuit generates a high frequency alternating field. When a conductive electrical material reaches said field, Foucault currents that subtract energy from the resonant circuit originate according to the law of induction. Consequently, the amplitude of oscillation decreases. This change becomes a switching signal. From this principle of operation it follows that the metals where the device is fixed will be detected and when the electronic seal of the container doors tries to be detached, the corresponding opening alarm will be generated; from the control module (Figure 3, item 15) that will send the alert to the GPS-2G module (Figure 3, item 13), and the latter in turn will forward it to the server center.

Technical specifications of the inductive sensor:

• Armor diameter: 12mm.

• Mounting distance: 2mm.

• Ideal detection distance: 0-1.6mm.

• Material: Chromed brass, oil, acid and alkaline proof.

• Standard censoring object: Ferrous metals.

• Power supply: 10-30 V DC.

• Frequency: <600 Hz.

• Output Current: <200mA.

• Operating temperature: -20 ° C to + 70 ° C.

• Protected against over-current and inverted polarity.

• Degree of own protection: IP67 (water and dust resistant)

This security system by means of inductive metal sensors differs greatly from the known security system by means of magnetic field sensors. The latter work in a totally different way: when current flows through an electromagnetic sensor and approaches a magnetic field that flows in a vertical direction to the sensor, then the sensor creates an outgoing voltage proportional to the product of the magnetic field strength and current . The main difference is that the magnetic field sensor needs magnets or electromagnets that work in conjunction with the sensors to create the field that the variable will be measured, and this can be altered in case of approaching a magnet externally. On the contrary, our inductive metal sensor is based on the measurement of the variable that interacts with the metal and not directly with the fields.

Therefore, metal is the means by which this variant travels, as the measurement is interfered with and an output is triggered. Consequently, magnetic sensors are easily vulnerable by varying the electromagnetic field they measure or censor, whose variation we can alter by bringing a magnet or electromagnet external to the sensor in question.

Security 2:

In order to maximize protection against theft, contamination and violations of the merchandise, and make versatile the use of our electronic seal for other cargo and transport units other than the merchandise container, we have implemented a second security system (optional) by means of of a safety cable.

Security cable

Cable detector XLR-3 12V sensor (Figure 3, item 17). This is an optional and additional system to inductive sensors, which will be used when the electronic seal is placed in cargo and transport units other than merchandise containers. According to (Figure 2) it can be seen how the electronic seal includes two inputs (Figure 2, points 10A and 10B) of the XLR-3 male connector, standard RS-297-A, to connect a three-contact cable terminated in the XLR-female connector 3 (Figure 3, point 17). This type of connector is usually connected in balanced lines. "XLR" stands for eXternal Uve Return, in Spanish "Active External Return". The "3" indicates that it has 3 pins or pins (Figure 2, points 10A and 10B). The male connector inputs mounted on the device have an internal wiring that supplies a voltage of 12 V through PIN 1 of the XLR connector, this electronic input passes through the external cable and enters through PIN 1 of the XLR connector, so that, if the supply of this voltage is interrupted by the analog input of the controller that includes the device, it generates an immediate disconnection alarm (this alarm is generated both in the event that the sensor cable is disconnected from the equipment, as if cutting or trying to sabotage said sensor cable). Pins 2 and 3 of the XLR connectors are intended for charging the two lithium batteries included in the equipment (Figure 6, points 16A and 16B). Charging can be done from the XLR connector (Figure 2, points 10A and 10B).

As explained (Figure 6) all components are unified and physically located in a single receptacle of dimensions that allow easy transport and placement in the container with one hand, allowing to secure the doors of the container and at the same time Hold on tightly to it. This makes it resistant to inclement weather and vibrations, blows or sudden movements caused by manipulation or the poor state of the roads and roads where it travels, while avoiding the generation of false opening alarms. It has a degree of protection IP65 totally waterproof and protected against water jets and also complies with the UL 94V2 standard of flammability.

As can be seen (Figure 2), the seal externally has an easily visible identification number (Figure 2, point 7), LEDs with light signals with which the various programming states of the equipment are represented (Figure 2, point 8), as well as alarm indicator (Figure 2, point 9). Wifi module integration

Our electronic seal offers a compact and integrated Wifi SoC solution to offer communication and data download services, with efficient energy use. Using its full and autonomous capabilities of Wi-Fi networks, the device is capable of operating independently or as a slave of an MCU host.

This integrated Wifi is located in the control module (Figure 3, point 15), and operates with high cache speed, which optimizes system performance and memory. In addition, this control module includes a 256Kb microcontroller support and control compatible with the integrated Wifi, through SPI / SDIO or I2C / UART interfaces.

In this way, the Wifi module allows you to communicate with mobile devices such as tablets, smartphones or laptops, and download for example electronic documents or information from the internal memory of the electronic seal, such as reports of container trip alarms, routes, among others. The design includes antenna switches, Balun RF, low noise power amplifier, filters and power management modules. In such a way that it offers features such as:

Description of the components of the Electronic Seal

Our electronic geo-locator seal has been designed in a modular way, so that in other models or versions, other modules of different compatible technologies can be optionally incorporated in addition to the current components, such as: a) One hundred percent satellite communication module (additional to the current GPRS and GSM).

b) Bluetooth module for the purpose of transmitting customs, commercial documents and downloading reports.

c) RFID communication module, to interact with temperature, humidity, and light sensors.

The electronic structure has already adapted the necessary connections for the optional modules described, lacking only the integration and configuration of the modules in the satellite tag software.

Material

As mentioned above, the receptacle is made of polyamide injected with fiberglass, a material that makes it highly resistant to impacts and to which an additive is added to minimize the temperature that it can reach due to the heat dissipated by the electronics and the absorbed by working under the sun's rays. In (Figure 1) its rear part is shown, which has been provided with a gutter (Figure 1, point 5) or groove arranged axially so that it integrates and adapts to the rubber that serves as a joint in the closure of the two doors of the container; in such a way that by placing the anchored seal on the seal that seals the closure of the two doors, said protruding rubber seal is absorbed by the gutter or channel of the back of the seal and consequently the adhesion surface of both the inductive metal sensors (Figure 1, points 2A and 2B), such as the eight neodymium magnets (Figure 1, points 1A to 1H), be one hundred percent. In the case of transport units other than sea containers, the operation is even easier due to the absence of the rubber gasket that they incorporate. The installation of the electronic seal must be carried out in the joint between the two doors of the container, ensuring that each of the sensors is armed and detecting the metal of the doors.

Therefore, the seal is not condemned to the bars and sabotage on them is no longer possible. The safety of the assembly ensures that if you cut the closing tubes of the This container cannot be opened without issuing alerts since the device is installed (attached) between the two doors of the container. Its installation or anchorage to the container door does not require installations of previous components or complements, nor does it depend on the bars of the same, unlike known electronic seals.

On the other hand, this arrangement favors the advantage that the electronic seal is integrated into the container structure, independent of the door bars, so that it does not protrude from the vertical of the door bars. The speed of placing the equipment in the container greatly favors the flow of transport units and prevents congestion or rows of containers in the exit areas.

LEDs

The equipment includes two LED indicators (Red / Blue) located at the top of the device that are responsible for indicating the different states in which the device can be found. The red color (Figure 2, item 9) indicates that some alarm occurred and the blue (Figure 2, item 8) indicates normality. The different flashing frequencies of the LED inform the operators of the current state of the seal, such as "Programming in progress, pending authorization of placement and pending departure", which allows them to proceed with the placement of the device without consulting with The programming and monitoring center. This aspect of the states of the LEDs also influences the agility and fluidity of the placements in the load units.

On the back of the device, in an area not accessible when the device is placed in the container, a tricolor LED (Figure 1, item 4) indicates the battery status / capacity (Green / Yellow / Red). GPS

The GPS locator is the main component of the device. Its main components are:

- Leon G 100 Quadband 2G U-Blox modem.

- GNSS Multichannel Chip (GPS + Galileo / GLONASS) - - ARM7 TDMI Processor

- Eight megabytes of flash memory and 2 mb of RAM.

- Integrated antennas for GSM and GPS with optional connectors for external antennas. - A digital input.

- Three configurable analog / digital connections as input or output.

- Sensors with interface via RS-232 / RS-485/1-Wire / CAN.

- Gyro-magnetic motion sensors in 3 axes.

- Internal temperature sensors.

- 1000 mA backup battery.

- Audio interface

- UBS 2.0 communication

- Supports communication with Garmin devices.

- Falcom PFAL programming language.

- Internet (TCP / UDP / HTTP / SMTP).

- A-GPS (online / offline / autonomous).

- Passive / active RFID connectivity via RS-232.

- CE certification (European community)

GPS performance and features

The locator acquires the GPS position at defined time intervals and transmits it using the GPRS network via the Internet to the TAG-Satellite platform. In addition to communication at fixed time intervals, any alarm or change of course that occurs greater than 60 degrees, or every certain meter, as defined, is also immediately communicated. The transmission time or frequency is modifiable from the platform; This means that if an emergency event occurs, the platform is enabled to change the transmission frequency from the monitoring center in real time (up to a frequency of positions every 15 seconds).

Both the transmission of positions and alarms, remains constant even after arrival at the authorized destination; that is, the device will continue transmitting once it enters its destination Geo-fence, until it is physically removed from the unit; which allows us to receive and know any alarm that occurs after the route is finished and until its removal or withdrawal in the authorized area of destination. In the travel programming windows, information entries have been included, for greater control and control of the trip, such as: identification of the persons in charge of placing / removing the marching, identification and telephone number of the driver, head plate, license plate container platform, bottle seal, shipping company, type of merchandise, importer, customs agent, carrier and identification of additional seals.

Through the inputs and outputs, the locator device manages the detection of the seal opening and the led indicators (Figure 2, points 8 and 9). Upon opening the seal a digital signal is interrupted, this event causes the locator to immediately transmit the alarm to the server. The device can also be programmed for sending and receiving SMS messages with different commands. Thus, in areas where there is no GPRS connectivity (eg jungle mountain area), the device sends the opening messages via SMS; Likewise, when there is no GPRS signal, the device is able to send us its location by means of a triangulation system for telecommunications antennas, facilitating its position in a radius of approximately 300 meters of precision. Additionally, by means of an internal motion / speed (acceleration) sensor, the locator informs the server if the seal is stopped or moving.

In addition, it integrates a high-performance 3-axis motion sensor, which allows the equipment to be linked to the physical conditions in which it is installed. As long as the equipment is installed along the lines of action of the motion sensor, it will be possible to obtain information on the movement of the device and to know on which axis such movement has occurred (horizontal / vertical / oblique-tilt movement). This last feature allows us, in the case of installation in the door of a container for example, to detect if the door is being disassembled or disassembled from the container box, sending the corresponding alarm in real time. In addition, there is the option of obtaining alerts depending on whether a certain level of acceleration has been exceeded in any of the three axes. When this happens, the equipment can generate an alarm message to send to the tracking server.

Using the internal temperature sensor of the device, it incorporates overvoltage protection by means of a reset fuse. It is also able to detect over internal temperature. The integrated Watchdog system allows automatic restart of the unit as soon as the problems reported by temperature or overvoltage disappear.

The team is able to detect any attempt to inhibit its signal, thanks to its algorithms and anti-jamming system. On the other hand, as another option that can be activated remotely, the system supports AES-128, which guarantees the reliability of communications since the data is transmitted encrypted. The battery and the SIM card are located in a secure compartment not externally accessible.

With the Eco-driving features included in the Spider Spider, it is possible to report alarms depending on the driving style of the charging units. This feature, which can be activated remotely, allows to collect a multitude of driving data such as braking, average speed, accelerations, abrupt changes of direction, speeding depending on the type of road, etc. In the case of a container, these reports of the events described may be indicators of aggressive driving as a result of a possible assault or evasive driving in the commission of a crime.

If the communication between the device and the server is interrupted, the device will continue to store the positions and try to re-establish the communication. As soon as the communication is reestablished, the stored positions are transmitted to the platform (regardless of the sending of a possible opening alarm via SMS).

The GPS module that integrates our electronic seal, has a horizontal accuracy of at least 2.5 meters, in 95% of the samples. The registered position is it retains in the internal memory of the device until a new trip is programmed, or while there is no GPRS communication at some point along the route. The device has an 8 MB flash memory, which gives it a storage capacity of more than 100,000 positions.

Each registered position contains the following information:

- GPS date of registration

- Device identification

- Latitude Longitude

- Speed

- Distance traveled since the last record

- Satellites in use

- GSM intensity

- Course

- Motion sensor

- Level of battery charge

- Alarm Identification

Battery, charging circuit and charger

In addition to the main battery module of the electronic seal (Figure 3, points 16A and 16B), the GPS module (Figure 3, point 13) located inside has a backup battery that will be activated automatically if the main battery of the electronic seal will stop working.

States, warnings and alarms implemented in the computer platform or management software:

Our platform has an automatic programming status management system, which supervises that each of the previously programmed rules is fulfilled to give the authorization to follow the programming process. These states or steps are used to guarantee the correct placement of the seal and are also physically reflected by means of the LEDs (Figure 2, points 8 and 9) that the seal has on its front face, for this reason light flashes have been established in different speed frequencies or combinations, which facilitates the operator in charge of placing it and avoids constant communication with the monitoring center or programming manager. Within the programming states of the electronic seal, the following are defined: a) Not prepared: the process where the trip is created and all the information necessary for post-system communication is added, in addition to trip information, such as trip, the assigned seal, the route number and the emails that should receive the alerts in real time, among other data and security parameters to include; in this state the information is not yet sent to the server for the device to load the data)

b) Pending sending to device: it is when the information is sent to the server and it is expected that the electronic seal obtains all the data and is programmed.

c) Programming in progress: at this time the seal is no longer in stand-by, loads certain internal parameters, turns on the GPRS and GPS antennas and connects the server to an established IP address and port and starts downloading the programming, in If there is no programming, the seal is disconnected from the server and returns to the Stand-By state.

d) Pending placement authorization: the device has already correctly received the complete trip schedule, but it is not physically within the authorized geo-fence of departure.

e) Pending placement: the device is programmed and is in the authorized exit geo-fence but has not yet been placed.

f) Placement without authorization: the device has been placed outside the authorized exit geo-fence.

g) Placed Seal: informs that the gear has been correctly placed in the container unit by means of an email.

h) Pending exit: the device has been correctly placed in its geography of origin and is awaiting exit.

Once the electronic seal is programmed and pending departure in its geo-origin of the container's trip, it will inform us in real time, through alarms or alerts that occur during the trip:

a) In progress / start of the route: the container leaves the authorized geo-fence and starts the trip. b) Excessive downtime: this means that the seal has stopped for longer than the authorized time. c) Excess travel time: this refers to exceeding the duration of the authorized travel time since starting the route without having reached its destination. It is the duration of the trip indicated in a number of minutes, included among the parameters that configure the trip or route.

d) Passage zones: they are both safe and insecure geo-fences, in a specific route. Applicable, for example, for unsafe areas with high risk of assault, or for rest areas or safe stops on scheduled routes.

e) Excess without GPS signal: this is when the authorized time without GPS communication was exceeded.

f) Excess without GPRS signal: this is when the authorized time without GPRS communication was exceeded.

g) Route exit: refers to when the seal leaves the authorized map route assigned to the programming.

h) Low battery: in the low battery alert based on an already defined parameter. i) Opening during the current trip: it is the unauthorized opening of the container during the trip, without having reached its authorized destination.

j) Arrival at destination: it is the arrival at the authorized final destination.

k) Opening at destination is the opening of the container within the authorized destination. I) Withdrawal of the seal / End of the trip: it is the removal or opening of the container within the authorized destination.

All these states and their respective alarms are reflected and visualized on the platform through the personnel of the monitoring center. In addition to the warnings and visualization in the monitoring center, the computer platform sends, in real time, all alarms, or the selection of them that are set, to the predetermined emails (for example to the monitoring staff, police fiscal control, security company and / or client, among others).

Web Computing Platform

The communication diagram explains the flow of information (Figure 5). The system information is replicated on two independent servers, one of which acts as host-swap backup of the other and with a guaranteed bandwidth of 100 Mbps. All communications software architecture is developed using Java language and runs on systems Linux operating. The platform consists of different processes that can be distributed on several servers. These processes are:

GalileoComm

Communication processes between the different types of locator devices and the platform. It is responsible for storing in the database all the information that arrives at the server from the location devices, processes millions of transactions a day and continuously.

Tomcat

Web application server and web services. It is the "visible face" of the platform, is responsible for presenting the information to the user. In addition to the web access available to users, the platform also extends by communicating with other information systems, such as those of the computer systems via web service of the different General Customs Directorates worldwide. According to the requirements of each country, the platform transmits the required information through the consumption of web services. The requirements of each country vary considerably and the platform must be customized for each case, while being enriched with each new requirement.

ReportServer

Report generator It is responsible for processing the information and composing the reports offered by the web platform.

Rule manager

Process that evaluates the events required by the platform, analyzing each position received and executing the actions defined for each event. It is the true "brain" of the platform.

GISServer

Geographic information system. It is responsible for verifying each coordinate received, checking whether said position is within or outside the established route, as well as the inverse resolution of the position by converting the geographic coordinates into a postal address. For this last task, the process is based on the Nominatim tool, which allows this type of search to be done on a local OSM database. Database server

As a database engine, the platform uses MaxDB, with more than a hundred gigabytes stored and carrying out 24x7 transactions has proven for years to be a highly reliable system.

Operation of the computer platform and programming of the electronic seal:

From the computer platform or management software we will perform all the necessary operations for the management of a trip of the electronic seal. The data introduced in this process are of vital importance for the correct development of the trip, therefore, the elaboration of the exit-arrival fences and the polygonal route of the allowed routes must be thoroughly verified; An error in any of the above steps may lead to obtaining useless information. The initial management of a trip involves the exchange of information between the computer platform and the electronic gear. This initial management can be divided into the following phases:

• Trip creation

· Trip Assignment

• Sending the programming to the march

Trip Creation

The informative data is added manually in the windows that are observed (figure 8) and with this they are stored in the database and then loaded into the electronic seal. Some of these fields are mandatory or merely for control, the following are mentioned in these:

• Travel (mandatory): This is the internal identifier of the trip on our platform. By agreement we will use the YYYYMMDDNN format; that is, year, month, day and a two-digit numeral with leading zeros. This information cannot be repeated and cannot be modified once the trip has been registered.

• Description (mandatory): Descriptive text of the trip. You can refer to the client, route, type of trip, etc. • N ° Trip and Ordinal (mandatory): Identifier of the trip provided by TICA.

• Device: Identifier of the gear that will make the trip.

• Vehicle (mandatory): Virtual identifier associated with the device for said trip. We can have defined several groups of vehicles each associated to a customer or type of customer. This data is what subsequently allows each client to access the platform to see only the private trips associated with their vehicles.

Other optional data

• Carrier: Identifier of the carrier to which the driver and the tractor (head), trailer (van) and fox (chassis / carriage) license plates belong. The designations or meanings can be modified as indicated by the DGA.

• Driver: The driver's name and identification document are specified, for this we must register the driver in the maintenance of carriers. Optionally you can also include the driver's phone number.

• Head registration: Head registration is specified. Like the driver we must also register the license plates in the maintenance of carriers.

• Container No.: Identifier of the container that is tracked.

• DUA (Single Customs Document): DUA number of transport

• Client: Identifier of the client or cargo owner.

• Shipping: It is the data of the shipping company that has carried out the sea freight of the cargo until its delivery on land.

• Van Plate: In case there is

• Cureña / Chassis Identification: If there is one

• Personnel in charge of placement / removal of marching: they are people in charge of performing the physical placement in the assigned geofence of departure and the retreat in the assigned geofence of destination.

• "Notes" tab: Here the operator can write down any incident of the trip.

It is recommended that annotations be made in case of any anomaly so that the technical department can consult them. There are also other optional data, required by the DGA and grouped in the "More Info" tab

• Additional seal, type and description: The computer platform contemplates the possibility of informing about other additional non-electronic seals that the transport may carry. In the event that such seals exist, this data can be reported. If the type of seal is "Custody", the required description is the name of the security company, otherwise it is not necessary to enter a description.

· Observations: You can fill in a text of observations.

It is important to note that there is other data that the user must not fill in manually, since this data will be automatically completed as the process progresses:

· Last state, date and time: Indicates the state in which the trip is located and the date on which the change occurred to that state.

• Actual departure date: This data indicates the date on which the marching in the container leaves the authorized geo-fence of origin.

• Actual arrival date: This data indicates the date on which the march enters the authorized destination geo-fence.

• Route: This data identifies the route that the march will take. This route is selected by the platform operator, it is composed using the polygons designed previously. The following data are extracted from the generated route:

· Minutes Duration: Estimated minutes of trip duration.

• Minutes Position: Expressed in minutes, it indicates how often the position readings should be taken and stored in the electronic gear. It could be every 60.30 or 15 seconds.

• Minutes Position: Expressed in meters, indicates how many meters the position should be taken and position readings sent to the platform.

• Minutes Maximum Stop: Maximum time that the march can be stopped before our excess stop time alarm goes off.

• Minutes Without GPS: Maximum time that the march can be without finding GPS coverage before launching the excess time alarm without GPS. • Minutes without GPRS: Maximum time that the march can be without finding GRPS coverage before launching the excess time alarm without GRPS, this alert is available to the TAG server, which ceases communication with the device, in case of not receiving information, an email is automatically generated informing of the situation.

• Minutes Mail Tracking: Time established in which a report of the PE's location is automatically sent to a specific email. Finally, for information on the evolution of the trip we can consult the tabs "States" and "Log Web Services.

• "States" tab: The computer platform has a history of the dates on which the state changes have taken place. Additionally, in this tab we add a counter that indicates how long it took that state to jump to the next step.

All the data described above can be completed stepwise as we learn the information. During this entire period the trip will be in the "Not ready" state.
