Description

METHOD AND SYSTEM FOR REMOTE ACTIVATION CONTROL

D E S C R I P C I O N TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of remote activation of actuators (eg detonators) and more specifically, to a method and system for controlling remote activation in a given area.

BACKGROUND OF THE INVENTION

A critical part of the mission to fight against all types of explosive devices and especially against improvised explosive devices (called by its initials IED) is the training of security forces. excellence responsible for the development of doctrines, tactics, techniques and procedures with which to face new threats, such as the International Demining Center (CID) of the Hoyo de Manzanares Engineers Academy (Madrid).

This center was founded in 2002 based on Spain's experience in demining issues in conflict zones and since then it has been established as a reference body for training international personnel in humanitarian demining tasks. The collaboration of this center and in particular, the knowledge of the Colonel Head of the Demining Center, Mr. Rafael Jiménez Sánchez, has been fundamental for, during the development of the present invention, to know the possible threats that soldiers have to face and your needs

The new wireless technologies will contribute to improving the training and training of combat forces, and increasing their capabilities on the battlefield, allowing not only to reproduce real conditions that soldiers will have to face (to be effective, we must replicate with possible realism the possible threat environments) and monitor the exercise in real time, but also record all the information generated throughout it for subsequent analysis

The capabilities that technology provides to a training system for the fight against LEDs, mines and other devices of this type can also be applied to remote explosive initiation systems, so that in the particular case of minefields, the The system complies with the Ottawa Treaty on the prohibition of antipersonnel mines, which prohibits the victim from activating the device, so that it is an operator who activates it remotely.

There are several remote controlled explosive initiation technologies. They usually consist of three parts:

1. Control unit: transmitter that can manage several receivers

2. Receiver: which can activate several detonators

3. Detonator: electric or electronic, which activates the explosive There are several patents published on the remote control initiation systems such as US 7,327,550 B2 "Frecuency Diversity Remote Controlled Initiation System", which describes a wireless transmitter that can activate several detonators through A first signal to be received by each receiver causes it to generate a second signal or US Patent, 8,621, 998, B2, "Remote Initiator Breaching System" that describes a blasting load initiation system. In this case, the transmission system generates and transmits several encoded signals that it can send through 16 channels. And 10 addresses per channel, so that the sending of the encoded signal from the transmitter to the receiver is possible by individual channels or all at the same time.

However, in the face of these existing systems and techniques (which in many cases present problems, for example, of robustness and security), there is a need for an intelligent remote activation system that minimizes the number of accidents, accidental activations ... and that allows its use both as training systems for security forces and bodies as well as for protection of outdoor areas, in an efficient, robust and safe way. These and other advantages of the invention will be apparent in light of the detailed description thereof. SUMMARY OF THE INVENTION

The objective of the present invention is to develop an intelligent and safe method and system of remote activation consisting of a network of devices for training systems of forces and security forces. The security forces of a training system in the detection and deactivation of explosive devices are provided by the present invention. The system will detect intrusions through a network of sensors and contemplates the connection to decoys or to acoustic and / or visual signal devices (flash and bang) that can simulate the detonation of an explosive device. You can also inform the control center.

In the case of being used as a force protection system, when the system detects the intrusion in a certain area, it will inform the control center to notify the intruder or to initiate action / detonation mechanisms after confirmation of the anomaly by operator. The operator is a person who can be located in the control centers: that is, in the monitoring and control units (which can be portable) or in the management nodes. To perform the activation safely, avoiding accidental activations, the system has a safety mechanism that requires at least double action by the operator. That is, it may be necessary for the operator to take a double action to initiate the mechanisms of action / detonation.

The activation signal can lead to an action by an actuator. For example, the activation signal could generate the load that starts a decoy or a smoke canister, but it could also lead to the lighting of a siren.

In a first aspect, the present invention proposes a remote activation control method in a given area, where the method comprises the following steps:

a) if a control system node (called an activation node) receives a message from another system node (called a communications base node) indicating that the activation of at least one actuator (eg detonator) is required, determine in the activation node that requires the activation of at least one actuator and go to step e) (activate the actuator), if not received said message, go to step b),

The message indicating that activation is required has been previously received by the communications base node from another system node called a monitoring and control unit. The communications base node, of which there may be one or more depending on the area to be covered, serves as a gateway between the monitoring unit and the activation nodes, since the area to be covered may be so extensive that these are necessary intermediate communication nodes so that the messages of the monitoring unit reach the activation nodes;

b) receive at the activation node information and / or an alarm message generated by at least a first sensor (these sensors are those that detect, for example, if there are intruders in the area they cover or any other anomalous circumstance, indicating that the actuators may have to be activated);

c) determine at the activation node, based on at least the information and / or the alarm message received from the at least one first sensor, if an alarm is activated (e.g. an alarm signal). As will be explained later, the activation node can consult other information, for example, from meteorological sensors, to decide if the alarm is false or if it seems true and therefore it must be activated.

d) if the activation node determines the activation of the alarm, determine if the activation of at least one actuator is required;

e) if it has been determined that activation of at least one actuator is required, the activation node sends an activation signal to at least one actuator;

f) the at least one actuator receives the activation signal from the activation node and initiates the activation (for example, the activation of the detonator load).

As a safety measure, for an actuator to activate, it may be required that the system be pre-assembled (that is, enabled to operate). When the system is not armed it is not possible for the actuators to act by initiating any activation (for example, detonating a load), since if the activation nodes are disarmed the control center does not receive alarms or any other type of notification or activation nodes send no activation signal and if the actuators are disarmed they cannot initiate any load. That is, depending on which nodes are disarmed, one action or another will be stopped, but the end result is that if they are not all armed, actuators will not be activated.

That is, for normal operation (as indicated above), it is assumed that the activation nodes and actuators are previously armed or that, if they are not previously armed, it is assumed that they are sent a previous armed signal or together with the confirmation of the alarm (to the activation nodes) or prior or in conjunction with the activation signal (to the actuators).

Communication between the different nodes and / or system units can be wireless or wired. For this, said nodes and units will have communication modules (transmitter / receiver) with communication interfaces that enable said communication.

In some cases (for example, depending on the configuration of the activation node or the type of alarm), the activation node determines that actuator activation is required whenever it determines the activation of the alarm without prior consultation with the unit. of monitoring and control.

However, in other cases, a prior consultation will be made to determine if the activation of a detonator is required, performing the following steps:

- send from the activation node a message to the communications base node informing of the alarm activation. In one embodiment, a signal is also sent from the activation node to at least one signaling and warning element to activate it, when the activation node determines the activation of the alarm.

- receive the activation node message in the communications base node and send it to the monitoring and control unit

- receive the message in the monitoring and control unit and determine if it confirms or cancels said alarm (this confirmation or cancellation will be given by the operator of the monitoring and control unit if there is one; if there is none or it is not enabled for it , as we will see later, it will consult with a management node and it will be the operator in that management node who will confirm and / or cancel the alarm).

- if the monitoring and control unit determines the confirmation of said alarm, send from the monitoring and control unit a message informing the confirmation of said alarm to the communications base node,

- receive the message informing the confirmation of said alarm in the communications base node and send it to the activation node

- in the activation node it is determined that the activation of at least one detonator is required only if it receives the message informing of the confirmation of said alarm from the communications base node (that is, if no message is received or a message is received canceling the alarm, actuator / detonator activation is not required). Irration or cancellation of the alarm may include:

- send a message to a system node (called management node) informing you of the alarm activation.

- determine in said management node (by an operator or operator supervisor, in the case that there are operators in charge of the monitoring and control units) whether to confirm or cancel said alarm and send a message to the monitoring unit and control with the result of said determination

- determine in the monitoring and control unit whether to confirm or cancel the alarm according to the result received from the management unit. In other words, it is the management node that decides whether to confirm the alarm (and therefore activate the actuator) or cancel it.

In any case, confirmation / cancellation is made in the monitoring and control unit or in the management node, always by an operator, that is, a qualified person. And as we have said before, to confirm the alarm (and therefore activate the actuator), it may be necessary for the operator to take a double action to initiate the actuation / detonation mechanisms. By double action it is understood for example that the operator press two switches for several seconds.

The management node may not be in the area to be controlled and may control several monitoring and control units (which typically are physically in the area to be controlled). That is, the management node is a control entity above the monitoring and control unit and can be used to control several systems.

Also, in step a) the message indicating that the activation of at least one detonator is required can be previously received by the monitoring and control unit of a management node with which the monitoring and control unit is communicated by a mechanism Wireless and / or wired communication. That is, the message can be generated indicating that the activation of a detonator / actuator is required from the management node or from the monitoring and control unit (in this second case, the unit can send a message to the management node indicating which generated said activation message).

The decision to confirm or cancel said alarm (whether taken by the management node or the monitoring and control unit) can be based at least partially on information collected by at least one additional first sensor deployed in the area (for example, a camera infrared or visible).

Before activating the actuator (detonator), a signal can be sent from the activation node to at least one signaling and warning element (which may be a light or sound element) to activate it (thus warning the possible persons that are found in the area, which is going to activate a load).

To determine in the activation node whether an alarm signal is activated (step c)), in one embodiment the following steps are performed:

- receive at the activation node information of at least one additional second sensor in wireless or wired communication with the activation node.

- determine at the activation node, based on at least the information received from at least a first sensor and at least a second additional sensor if the alarm signal is activated.

Sometimes, the activation of the detonators is done when communication between the nodes is lost. Thus, in one embodiment, the method also comprises the following steps:

- periodically send from the communications base node (or from all communication base nodes if there are more than one) check messages to the activation nodes with which said communication base node is in communication, using a first communication mechanism (the one commonly used for communications between the communications base node and the activation nodes);

- if, by means of these verification messages, the communication base node detects any anomaly in the communication with some activation node, the communication base node sends a message informing the anomaly to the monitoring and control unit;

- upon receiving said message, determine in the monitoring and control unit if the activation of at least one detonator is required based at least partially on information collected by at least one additional first sensor deployed in the area. This can be decided by the monitoring and control unit directly with the information available or can be consulted with the management unit and the management unit decides and communicates it later to the monitoring and control unit;

- if the monitoring and control unit determines that the activation of the at least one detonator is required, send a message to the communications base node indicating that the activation of the at least one detonator is required;

- receive the message at the communications base node indicating that the activation of the at least one detonator is required and send it to the activation node using a second communication mechanism other than the first communication mechanism. With this message, the method is started again, that is, the activation node receives it and sends a signal to the actuator to activate it. That is, since the first mechanism does not work, a second mechanism is used. The first mechanism can be a radio link at a certain frequency and the second communication mechanism can be a light beam or a radio link at a frequency different from that used by the first communication mechanism.

The first and second additional sensors can be for example: visible cameras, infrared cameras, radar systems, microphones or weather sensors. In a second aspect the present invention proposes a remote activation control system of actuators (detonators) in a given area, where the system comprises at least one monitoring and control unit, at least one communications base node, at least one activation and at least one detonator node (actuator), where:

- the at least one monitoring and control unit comprises a first communications module configured to communicate it bidirectionally with the at least one communications base node

- the at least one communications base node comprises a second communications module configured to communicate in a bidirectional manner the at least one communications base node with the monitoring and control unit and with the at least one activation node,

- the at least one activation node comprises:

- a third communications module configured to bidirectionally communicate the at least one activation node with the communications base node, with the at least one detonator node and with at least one activation sensor;

- a microprocessor card configured to:

determine the activation of an alarm depending on at least information received from the at least one activation sensor;

determine that activation of at least one detonator is required;

and send an activation signal to at least one detonator through the communications module if it determines that it is required the activation of said at least one detonator;

- the at least one detonator node is configured to initiate detonation (for example, load activation) when it receives an activation signal from the activation node.

The system can also comprise a management unit comprising a fourth communications module configured to communicate it in a bidirectional manner with the at least one control and monitoring unit.

The system can also comprise at least a first additional information sensor that collects information from the determined area where the system is deployed and that sends said information to the at least one control unit and / or at least one communications base node. In this second case, the information collected by the communications base node of these sensors would be sent to the monitoring and control unit.

The system may also comprise at least a second additional information sensor with which the at least one activation node is communicated.

The system can also comprise at least one signaling and warning element and where the third communication module of the activation node is configured to communicate the at least one activation node with the at least one signaling and warning element. As explained above, the activation node can activate these signaling and warning elements before activating the detonator and / or when an alarm is activated.

The detonation of the detonating node can activate a smoke canister or the start of an acoustic or visual signal (in case it is used in a training ground), or a load in the case of a force protection system.

To ensure the reliability of the communications, the second communications module of the at least one communications base node may comprise at least two communication interfaces to communicate with the communication node. activation. These interfaces use different communication mechanisms (radio and light beam, or radio communication at different frequencies) and when the communication base node detects failures in communication with the activation node using one of the communication interfaces, the second communication module Communications uses the other communication interface to communicate with the activation node.

This mechanism of redundancy in communications can also exist in the rest of the nodes and units of the system. Communications between the different nodes of the system can be wired or wireless. In one embodiment, the communication between the monitoring and control unit and the at least one communications base node and the communication between the at least one communication base node and the at least one activation node is performed by wireless communication (for example , radio or photonic communication) and communication between the at least one activation node and the at least one detonator node is done through wired communication (for example, coaxial cable, optical fiber and Ethernet).

The activation nodes and the detonating nodes may have a manual arming / disarming mechanism, so that if it is in the disarmed position they do not activate any activation signal (in the case of the activation node) or initiate any load (in the case of detonation node). Arming / disarming can also be activated by means of a configuration message from the monitoring and control units.

The at least one activation sensor can be mechanical (for example, pressure scale. Trap cable, contact clamp or switch) or electric (for example, visible or infrared video camera, motion detector, light beam cutting, acoustic sensor, presence sensor, timer, magnetic sensor, seismic sensor or radar).

The monitoring and control unit, the at least one communications node, the at least one activation node and the at least one power node and even the sensors may comprise one or more power batteries that may be connected to a solar panel to be recharged or recharged by connecting to a power supply network.

Finally, in a fourth aspect of the invention there is a computer program comprising instructions executable by computer to implement the described method, when running on a computer, a digital signal processor, an application-specific integrated circuit, a microprocessor , a microcontroller or any other form of programmable hardware. Said instructions may be stored in a digital data storage medium.

DETAILED DESCRIPTION OF THE INVENTION

The present invention proposes an intelligent and secure remote activation method and system consisting of several devices. This system will detect intrusions in a certain area and before initiating detonation it will inform the control centers to notify the intruder or so that system operators can initiate action / detonation mechanisms after confirmation of the anomaly. For this, it is proposed to have a two-way communication between the control units and the detonators, so that from the control center, once the confirmation of an alarm is received, an actuator can be activated, which can eventually be a detonator. This Remote Activation Controller system, also called Remote Activation Systems Controller (or by its acronym, CRsA) can be formed by the following elements: a) Management unit.

b) Monitoring and control unit.

c) Communication base nodes.

d) Activation nodes.

e) Detonating nodes and / or sensors / actuators.

The system requires the intervention of an operator that generates the activation signals in a safe way, avoiding a possible accidental activation, without prejudice to the fact that this intervention of an operator is carried out in the management unit or in the monitoring and control unit.

With the previous elements, this CRsA system can be used or in other words configured as:

1. Training system for security forces and bodies. 2. Protection system for outdoor areas, through unattended sensors, remotely and intelligently.

Figure 1 depicts the architecture of the complete CRsA system according to an embodiment of the invention. As can be seen in this figure, each CRsA system consists of one or more management units (1 to - 1z) that communicates with the monitoring and control unit (2), which in turn communicates wirelessly / radio or wired with one or more communication base nodes (3a - 3z), which in turn wirelessly or wired control one or more activation nodes, also called activator nodes (5a - 5z, 5'a - 5'z ). Additionally, different sensors (4a - 4z) are available that collect information for the management units (1) and / or for the monitoring and control unit (2). Each activation node will act wirelessly or hardwired on one or more detonators (6a - 6z, 6'a - 6'z, 6 "a - 6" z, 6 "'a - 6"' z) and on one or various signaling and warning systems (7a - 7z, 7'a - 7'z, 7 "a - 7" z, 7 "'a - 7"' z).

The control units where alarms are received and actions are initiated are divided into two types: · Management units (1). These elements are optional and are understood as a management entity to the monitoring and control units (2). The management units (1) may not be physically at the installation site and could control several monitoring and control units (2) physically located at different locations. As the monitoring units, they receive alarms and can initiate the mechanisms of action. However, unlike the previous ones, the management units (1) can interact on several different systems.

• Monitoring and control unit (2). This element is preferably unique per installation (although in other embodiments there may be more than one such unit). It is the element that receives the alarms and initiates the actions on a single installation. It is also responsible for communication about the nodes of communications (3) and can access sensor information (4a-4z) such as visible, infrared cameras, radar systems, etc.

Communication between the management units (1) and the monitoring and control unit can be carried out in a wired manner via fiber optic link,

Ethernet or any other wired media; and wirelessly through a radio frequency link, satellite link, etc.

The next element of the system is the communications base nodes (3) deployed in the installation. These elements act as a communication gateway between the monitoring and control unit (2) and the activation nodes (5) (that is, the communications node can simply pass the information it receives from the activation node to the monitoring unit and vice versa). To guarantee all communication possibilities, in a preferred embodiment the direct vision between them and the activation nodes (5) must be guaranteed (in another embodiment, for example, repeaters could be used). The control units can also access the information present in auxiliary sensors (4a-4z) displayed. These sensors can be of any type, such as visible, infrared cameras, radar systems, microphones, weather sensors, etc. Below are the activation nodes (5). These activation nodes communicate with the monitoring and control unit (2) through the communication base nodes (3). To the activation nodes (5), one or more actuator nodes (eg detonators) (6) and one or more signaling and warning actuator systems (7) are connected to notify a possible violator that a system has been activated. detonation

The monitoring and control unit (2), the communication base nodes (3) and the activation nodes (5) communicate with each other, following the structure of Figure 1 (i.e. the monitoring and control unit (2) ) communicates with the activation nodes (5) through the communication base nodes (3) that each communicate with a group of activation nodes). In turn, the activation nodes each communicate with one or more detonating nodes and signaling systems. These communications are made through one or more of the following communication mechanisms: • Wireless Communication: distinguishing:

o Radio Communication including low frequency communications, telephony, WiFi, high frequency. Including civil and military bands.

o Photonic Communication understood as the transmission of information through a beam of light or laser.

• Wired Communication: Using coaxial cable, fiber optic, Ethernet, etc.

It is important to emphasize that the communication mechanisms between the elements of the system may be different. For example, the communication between the monitoring and control units and the communication nodes could be done through a secure radio communication (such as that provided by Spearnet equipment), the communication between the communication nodes and the activation nodes could be radio in telephone band; and the communication between the activation nodes and the detonating nodes could be wired.

To provide the system with greater robustness against electronic warfare attacks, the system may have different redundant communication mechanisms. For example, in the event that the radio signal is disturbed, an optical link in the free space or a wired link would allow arming and / or activation directly the activation nodes. Additionally, the system develops intelligence to avoid possible inhibitors: The communication nodes, in a preferred embodiment, repeatedly interrogate the activating nodes. These in turn repeatedly interrogate the detonating nodes. In this way, the control center detects when any of the usual communications has not stopped working. When this occurs, an aim is automatically made, for example, by means of the visible, infrared and / or radar systems cameras, towards the area where the communication has been interrupted. If the anomaly is confirmed, the operator is informed so that he can initiate the detonators in a wired manner or by a photonic signal where the intrusion is detected (this activation may affect one or more detonating nodes). The management units may consist of a hardware element such as a computer, tablet or smartphone (with software that runs on these devices and that may be part of the CRsA system) and a communications element (wired or wireless) that allows communication with the unit or units of monitoring and control. With this software, the control and management of more than one installation will be allowed. This control and management will include alarm management and interaction with the different actuator elements (detonators or signaling / warning systems). The software of this element will have the same options as that of the monitoring and control units with the difference that more than one installation can be controlled. Additionally, the software of the management units will be able to block the operation of the control and monitoring units or to request confirmation of their actions. In short, these management centers are constituted as the element of general control over the entire CRsA system.

The monitoring and control units may consist of a hardware element such as a computer, tablet or Smartphone (with software that runs on these devices and that may be part of the CRsA system), one or more communications elements that allow communication with the management units (if any) and with the communications base nodes and one or more communications elements that allow direct communication with the sensors (visible, infrared cameras or radar systems) deployed in the installation. Optionally you will have a communication module by means of a light beam that allows communication (through direct vision) with the communication base nodes. The software present in the monitoring and control unit allows the user to monitor and control the information from the activation nodes. In the same way the software itself is responsible for receiving and sending notifications to the management units. In the application interface you can see the map of the scenario where the communication base nodes, activation nodes and detonators are deployed. This map shows the position and status of each of the activation nodes and the different detonators associated with each activation node. The possible states for the activation nodes and for the detonators are three: disarmed (green), armed (yellow) and activated (flashing orange). From this interface the operator can arm, disarm activation nodes and detonators (actuators) and activate detonators remotely. In the same way, the user can program arming and activation sequences from the interface, as well as the configuration of the activation nodes.

Figure 2 shows the architecture of a communications base node (3) according to a preferred embodiment of the invention. These nodes are responsible for communicating one or more activator nodes (5a-5z) with the monitoring and control units (2) in a wired or wireless / radio manner. Additionally they collect and forward information from one or more auxiliary sensors (4a-4z) displayed. Each communication base node consists of its own microcontroller card (8) (also called a microprocessor card), its own communications module (9) with physical input (for example Ethernet or similar) to connect communications equipment via secure radio and / or one or several radio interfaces; and optionally for its power system (10) composed of one or more batteries, solar cells, etc.

The communication between the activating nodes and the monitoring and control unit is carried out through a wired or wireless / radio communications protocol that is implemented in a communications module (9) present in the microcontroller board (8) or external to it (as shown in figure 2) which in turn have one or more network interfaces. Within these interfaces, the communications node may have a communication element by means of a light beam to communicate with the activation nodes. This communications element will be implemented in the communications module (9). The function of this node is to bridge the two systems. Using the microcontroller board (8) it processes the messages from the activation nodes and the monitoring and control units. Through this board, information is also received from visible, infrared cameras, radar systems, microphones, weather sensors, etc. (4) deployed in the installation. The information of these sensors is forwarded to the monitoring and control unit. Optionally, the communications base node can have a power system (10) formed by one or more rechargeable batteries connected to solar panels or that can be charged to the power supply network. Figure 3 shows the architecture of one of the activation nodes (5) according to a preferred embodiment of the invention. An activation node (also called the activating node) acts on one or more detonators either wired or wireless / radio (6a - 6z) and on one or more signaling and warning systems either wired or wireless / radio ( 7a - 7z). The activation nodes have several inputs that collect the signals from the sensors: wired and / or wireless / radio (11 a - 1 1z), which, as shown below, can be for example: pressure plates, activation timed, by magnetic contact, by interruption of light / laser beam, by trap cable, by contact, by movement, etc. Inside the activation node is composed of a microcontroller card (12) that houses its own algorithms (13), a communication module (14) that can have several interfaces such as WiFi, Bluetooth, light beam and other radio frequency . Additionally, the activation node will contain a physical activation / deactivation mechanism (15) composed of one or more subsystems. In addition, it should be noted that the activation nodes will consist of a power system (16) that can be composed of an internal battery, a network charging system, solar panels, etc. The activation node may also have one or more information sensors (17a-17z) that provide field information for the activating node.

These activation nodes communicate with the communication base nodes (3) in the ways described above. Similarly, the activation nodes communicate with the detonating nodes (6a - 6z) wirelessly or hardwired through the communication module (14) that has different network interfaces.

These nodes have several physical inputs (11a-11z) that cause an alarm (for example in the case of minefield) or activation (for example, in the case of training camp). So you can start the detonators (6a - 6z) to activate a lure or smoke canister in case of training ground, or a load in the case of a force protection system. The possible inputs of the sensors of the activation nodes can be mechanical and electronic, distinguishing the following:

1. Mechanical inputs can be, among others: • Pressure scale. A pressure scale can be connected to the activation node through an external connector. When a subject activates the scale, the activation node receives the activation information.

• Cable trap. A cable is provided which, in case of being cut, starts an alarm for the activation node.

• Contact clip. A clamp is available that sends a signal for relief

• Switch

Electronic tickets can be, among others:

• Visible / infrared video camera. By analyzing the scenario, it is possible to detect a subject in the field of action of the trigger node. If a change of scenario is detected, an alarm can be generated for the activation node.

• Movement detector. There is a sensor that monitors the movement, if the amount of movement exceeds a certain threshold an alarm is generated for the activation node.

• Light beam (photoelectric) or laser cut. If a subject crosses the beam of light, an alarm is generated for the activation node.

• Acoustic sensor. A microphone is provided with an alarm to the activation node in case of contact, where in case the loudness exceeds a certain threshold, an alarm is initiated for the activation node.

• Presence sensor. An alarm for the activation node is initiated by a presence detector such as infrared.

• Timer. A sensor may be available that initiates an alarm towards the activation node after a temporary event.

• Magnetic sensor. It will be possible to have a magnetic sensor that in case of opening the circuit, an alarm will be generated towards the activation node.

• Seismic sensor • Radar, there are sensors capable of measuring distance and speed of the potential target.

In the same way, each activation node may have one or more signaling and warning elements or systems (7a-7z). These system elements may be bright or sound. The activation nodes will act on these systems when a subject has activated any of the activation inputs, to notify you that one or more detonations can be initiated. As an example, the system could be configured so that with the first activation of some of the activation inputs (1 1a-11z), the activation node would activate the signaling and warning systems (7a-7z); while with the second activation, the activation node could initiate the detonation of one or more detonators (6a-6z) in the case it will serve as a training ground. It is important to highlight the presence of wired or wireless information sensors (17a-17z) controlled from the activation nodes. These sensors, such as weather sensors, send the information wirelessly or hardwired to the microcontroller card (12). The algorithm (13) present in the microcontroller card collects the information present in these sensors and processes it in real time. In case of receiving any alarm from any of the activation inputs (11), the algorithm before generating the alarm or activating the actuator / detonator, can take into account the information collected through these sensors (17a-17z). It is important to note that the information coming from these sensors will not initiate the activation mechanisms of the detonators.

The intelligence of the activation nodes is implemented in the microcontroller card (12) where the different algorithm (13) is executed. The algorithms present in the activation nodes can be configured from the control software present in the monitoring and control unit and in the management units.

The microcontroller card monitors in real time the status and / or values of the different sensors that make up the activation inputs. The algorithms process the information coming from said sensors and based on the configuration values, the alarms that will be sent to the units of information will be generated. monitoring and control, through the communications base nodes. The sensors that make up the inputs of the activation nodes can be of two types: binary or analog. If a sensor is binary, the algorithm only monitors its value. If a sensor is analog (or discrete values), the algorithm monitors the evolution of the sensor value and computes an adaptive threshold in real time, a type of constant false alarm algorithm. If the threshold is exceeded, the algorithm generates the alarm for the monitoring and control center. On the other hand, the algorithm can have access to additional information from the information sensors (17a-17z). Algorithms can use that information to filter false alarms and avoid activating unnecessary actuators. As an example about the use of this information, suppose a sensor that reports weather information to the activation node. In that case, suppose that the activation input corresponding to the motion sensor is activated. In that case the algorithm will check the information of said meteorological sensor to act on the alarm generation threshold depending on the meteorology.

Additionally, the activation nodes may have a manual activation / deactivation system (15) composed of one or more physical switches. These switches will arm or disarm the activation node but will not initiate any detonation.

Finally, each activation node has a power module (16) that can be internal or external, which in turn may or may not be rechargeable. This system can be a battery connected to a solar panel for recharging or a battery that can be charged to the network.

Figure 4 shows the diagram of a detonating node according to an embodiment of the invention. In the simplest case, the detonator node (6) will be composed of an initiator circuit, which can be connected via a pair cable to an activation node, and a load or a decoy such as a smoke canister or sound signal

(for example, in case of training camp). Activation is initiated by the passage of current through the cable to the initiator. In the general case, described in Figure 4, the detonator node (6) will be constituted by a microcontroller card (22) that processes the information from the activation nodes (6) through of the communication module (18) that can have one or more communication interfaces. This module can have a physical input (Ethernet or similar) to connect a radio communications equipment safely, as well as several wireless network interfaces such as WiFi or other radio frequency bands. The detonation nodes will have a power system (20) consisting of one or more internal batteries (for example, rechargeable batteries connected to a solar panel). Additionally, each detonating node has a manual arming / disarming system (19) composed of one or more switches. The status of this arming / disarming system takes precedence over the activation messages from the activation node. Finally, each detonating node has one or several explosive charges in the case of a minefield and one or more smoke boats or other signals (for example, acoustic or visual) in the case of a training field (21). Figures 5 to 1 1 show different schemes of the activation procedure of the detonating nodes.

The activation of the detonators (6) can be initiated in the monitoring and control unit (2) as in Figure 5, which shows the activation mechanism from the monitoring and control unit. The system operator starts the activation of one or more detonators from the graphic user interface present in the monitoring and control unit, this unit generates a message (M 1) that is addressed to the communications base node (3) where it is located the activating node of the selected detonator (s). In turn, the monitoring and control unit sends an informational message (11) to the management units on which it depends. When the communications node receives the message, it sends the message (M2) to the activation node (5). When the message is received, the activation node may, optionally, send a message (M3) to the signaling and warning systems (to all or only to one or more of them) to notify the possible intruder. Finally, after an optional time interval, the activation node sends a message (M4) to the detonating node (s) selected to initiate the detonation.

The activation of the detonators (6) can also be initiated in the units of management. Figure 6 shows the activation of a detonator from one of the management units. An operator located in one of the management units can initiate the activation mechanism by sending the message (M1) to the monitoring and control unit (2) on which the detonating node (or detonating nodes if more than one) depends on Start. When the monitoring and control unit receives the message, it forwards it (M2) to the communications base node to which the activating node that controls the selected detonator (s) belongs. The communications node sends a message (M3) to the trigger node, which in turn sends (optionally) the message (M4) to one or more of the signaling and warning elements and another message (M5) to the detonator to initiate the explosive charge, in case of minefield configuration, or the smoke canister or other element in the case of training camp.

Figure 7 shows the activation mechanism in an embodiment of the invention, when said mechanism is initiated in one of the activating nodes. Specifically, when the mechanism starts autonomously by the activation node, from the signals coming from the activation inputs present. If one (or several) of the activation inputs (1 1a-11z) present in an activating node (5) is activated (for example because it detects the presence of an intruder), said input sends an alarm message (M1) to the activation node The activation node receives the message and, if armed, optionally collects the information from the information sensors (17a-17z) and executes the algorithm present on the microcontroller card, processing the information received from the sensors and / or of the activation inputs. If, as a result of this process, the activation node determines that an alarm has to be generated (in other words, the alarm generated by the activation inputs is confirmed), optionally activates the signaling and warning systems through of the message (M2) and sends the alarm informing of the activation of the input to the communications base node through a new message (M3). The communications base node sends the alarm message (M4) to the monitoring and control unit where a system operator receives the message. The system operator picks up the alarm, being able to cancel or confirm it. Additionally, an informational message (11) is sent from the monitoring and control unit to the management units. The monitoring and control unit sends the operator message (M5) towards the corresponding communications base node, this in turn sends the message (M6) to the corresponding activation node. The activation node receives confirmation or cancellation from the operator. If the message is activation (confirmation), the activation node will communicate with one or more of the detonating nodes in turn to initiate detonation (M7). In an alternative embodiment, a message is only sent from the monitoring and control unit to the communications base node if the operator confirms the alarm. That is, if the operator cancels it, the activation node does not receive any message from the communications base node and in the absence of a message, it will not activate the detonating nodes.

Like Figure 7, Figure 8 shows the activation mechanism initiated from the activating nodes but in this case confirmation is required by the management units (1a-1z). One of the activation inputs of the activating nodes detects the presence of an intruder and sends an alarm message (M1) to the activation node. The activation node receives the message and, if armed, optionally collects the information from the information sensors (17a-17z) and executes the algorithm present on the microcontroller card, processing the information received from the sensors and / or of the activation inputs. If, as a result of this process, the activation node determines that an alarm has to be generated (in other words, the alarm generated by the activation inputs is confirmed), it sends the alarm informing of the activation of the input to the communications base node through a new message (M3) and optionally activates the signaling and warning systems through the message (M2). The communications base node sends the alarm message (M4) to the monitoring and control unit. The operator of the monitoring and control unit receives the alarm but awaits confirmation from the management units. For this, the monitoring and control unit (either because the operator activates the sending or because the software of the unit does it automatically) sends the message (M5) to one of the management units. The operator (s) located in the management unit can confirm or cancel the alarm. The result of the operator's choice (confirmation or cancellation) passes through the system through messages M6 (from the management unit to the monitoring and control unit), M7 (from the monitoring and control unit to the communications base node) and M8 (from the base node of communications to the activation node) until you reach the activation node that receives confirmation or cancellation from the operator. If the message is activation, the activation node will communicate with the detonating nodes to initiate detonation (M9). In an alternative embodiment, a message is only sent to the activation node if the operator of the management unit confirms the alarm. That is, if the operator cancels it, the activation node does not receive any message from the communications base node and in the absence of a message, it will not activate the detonating nodes.

Figure 9 shows the activation mechanism of the actuators (e.g. detonators) from the activation node autonomously, without using the communication base nodes and the monitoring and control units. In this case, the activation node receives an alert message (M1) from one or more activation inputs. Once said message has been received, the activation node optionally sends a message (M2) to the signaling and warning systems to notify the possible intruder. Finally, the activation node sends a message (M3) to one or more detonating nodes to activate them (activating a smoke canister or an acoustic or visual signal). This activation mechanism autonomously only applies to training systems, and never for a detonator to activate any type of explosive charge.

Figure 10 shows the actuator activation mechanism due to interference in communications. The communication nodes and the activating nodes are exchanging messages (M 1) and (M2) to check the correct functioning of the equipment and / or communications. These messages will typically be messages through a wireless radio or wired interface. If any external element to the CRsA system interrupts that communication and the communications node detects it (for example by not receiving a response to any of the check messages) the communications node sends a message (M3) to the monitoring unit and control informing of such interruption. The operator of the monitoring and control unit will consult the information of the sensors (4a-4z) displayed for additional information (11). In case the operator observes an anomaly, it will send a message of information (12) to the management units and at the same time will initiate the activation mechanism by sending the message (M4) to the communications base node. This communications node will activate one of its additional communication interfaces (such as light beam, radio link to another frequency, ..) and will send a message to the trigger node (M5) to start the activation of the load and the activation node sends a message (M6) to one or more detonating nodes to activate them. Optionally, a message (M7) will be sent from the trigger node to the signaling and warning systems to notify a possible intruder. Figure 11 shows the activation mechanism of the actuators (eg detonators) due to interference in communications with confirmation of the management units. The communication nodes and the activating nodes are exchanging messages (M1) and (M2) to check the correct functioning of the equipment and / or communications. These messages will typically be messages through a wireless radio or wired interface. If any external element to the CRsA system interrupts that communication, the communications node sends a message (M3) to the monitoring and control unit. The operator of the monitoring and control unit will consult the information of the information sensors (4a-4z) displayed for additional information (11). If the operator observes an anomaly, it will send a message with the anomaly to the management units (M4). The operator of the management unit will confirm or cancel the alarm by sending the message (M5) to the monitoring and control unit, which in turn sends the message (M6) to the communications base node. In the event that the message received is an alarm confirmation, this communications node will activate one of its additional communication interfaces (such as light beam, radio link to another frequency, ..) and send a message to the trigger node ( M7) to start the activation of the load and the activation node sends a message (M8) to one or more detonating nodes to activate them. Optionally, a message (M9) will be sent from the trigger node to the signaling and warning systems to notify a possible intruder. If the message received by the communications base node is cancellation or does not receive a message, the communications node does not send any message to the trigger node to initiate the activation of the load. By way of recapitulation, preferred embodiments of the system and the fundamental elements of said system are presented in Figures 12-15.

Figure 12 shows the architecture scheme of the CRsA system in a preferred embodiment of the invention (Figure 12 does not show management units). The system, in its preferred embodiment, may be used for the application for which it has been designed (training field). The system will be constituted in its preferred embodiment by a monitoring and control unit (2) that will be the element from which control will be made of both the minefield and the training field depending on the use of the system. This monitoring and control unit (2) will communicate wirelessly (radio at different frequencies, light beam, etc.) with the communication base nodes (3) deployed by the installation. Additionally, from the monitoring and control unit, information from other external sensors (4a-4z) deployed by the installation such as visible, infrared cameras, radar systems, microphones, etc. will be accessed. This information may be used to initiate actuator activation mechanisms. The communications base node (3) is the element responsible for communicating the monitoring and control unit (2) with the activating nodes (5a - 5z, 5'a - 5'z). In your preferred embodiment both communications will be wireless either radio at different frequencies or light beam. To ensure immunity against interference, in the preferred configuration, the direct line of sight between the communication base nodes and the actuator nodes associated therewith must be guaranteed. Similarly, the communications base nodes will be able to access the information of the sensors (4) deployed by the installation to be forwarded to the monitoring and control unit that is the decision-making center. In the preferred embodiment, the activating nodes (5a - 5z, 5'a - 5'z) are wired to the detonating nodes (6a - 6z, 6'a - 6'z, 6 "a - 6" z , 6 "'a - 6"' z) and the signaling and warning elements (7a - 7z, 7'a - 7'z, 7 "a - 7" z, 7 "'a - 7"' z).

Figure 13 shows the block diagram associated with the communications base node (3) in its preferred embodiment. In this configuration, this node communicates wirelessly (radio at different frequencies, light beam, ...) both with the monitoring and control unit (2) and with the activating nodes (5a-5z). In inside it will contain a microcontroller card (8) whose main function will be to manage the communications module (9) (with one or several communication interfaces both wired and wireless) and monitor the status of the power system (10). In this configuration, the communications node acts as a bridge between the monitoring and control unit and the activating nodes.

Figure 14 shows the block diagram associated with the trigger node (5) in a preferred embodiment. In its basic configuration, this element will communicate wirelessly with the communication base nodes (3) and in a wired way with the detonating nodes (6a-6z) and with the signaling and warning elements (7).

The detonator node will have different activation inputs (11 a-1 1z) (for example, wired) mechanical and electronic that will initiate the activation processes. Additionally, the activating node can access additional information sensors (17a-17z) to prevent the generation of false alarms due, for example, to weather conditions. Inside, the activating node consists of a microcontroller card (12) whose functions are to monitor the activation inputs, execute different algorithms (13) associated with these inputs, manage the communication interfaces associated with the communication module (14) (with one or several communication interfaces both wired and wireless) and monitor the status of the power system (16). Additionally, the node has a manual arm / disarm system (15).

Figure 15 shows the block diagram of the detonator node (6). In its preferred configuration, this element communicates wired with the activating node (5). Inside it will consist of a communication module (18) that will manage the wired communication and a charge that will be explosive in case of configuration in the field of mines and of smoke canister or other element (acoustic or visual signal) in case of configuration in training camp (21).
