STATE OF THE PREVIOUS TECHNIQUE

25 The number of devices that surround users and can provide information through sensors is progressively increasing thanks to what is known as the "Internet of Things" paradigm, whose acronym is IoT. The user can access data from the sensors in a simple way and act according to specific needs. Thanks to that, applications that until now were utopian

complicated implementation or its high cost, are making their way among the common public. This paradigm opens the possibility to the creation and access of large networks of sensors and actuators on wired or wireless media based on widely proven technologies such as TCP / IP or HTTP.

5

Many applications of the internet of things can be foreseen, from the domotization of a home, to personal area networks to monitor physiological variables, through defense, "smart cities", infrastructure or industrial control systems. environments that can make use of and benefit from the control and flexibility offered by sensor networks, and thereby provide greater security, control, economic and energy savings, increased level of automation, parameter optimization, etc. among other advantages .

In order to make these applications, a central control system is needed that is responsible for the logic, configuration, access and coordination of the control system and a set of sensors and actuators (also called transducers) that allow acting on the aforementioned systems.

This poses several problems. The main one is due to the amount of transducers 20 necessary to provide any of these systems with basic functionality, another problem concerns the heterogeneity of said sensors and actuators. These problems are increased when you want to provide a network of sensors to an environment that was not originally conceived under this premise, such as the case of implementing a home automation system in an already built house or an environmental control system in a city. .

Additionally, the means to communicate with the transducer network (physical or wireless), the set of protocols to communicate and manage all the elements that are prone to be controlled, the configuration system and the rules for the processes of

automatic control and other underlying aspects, have caused that due to the large number of variables there is no established standard, and that the implementation of such systems is expensive and complicated.

5 One of the first issues to address when designing a sensor network is the type of technology to use, especially those based on wireless type. The two best-known and widely used wireless interconnect technologies currently are Wireless LAN IEEE 802.11 (WLAN) and Bluetooth IEEE 802.15.1. A priori, none of them is adequate since they have been designed for high-speed data transfer, making it difficult to fit them into the necessary power and cost requirements in the sensor networks.

It is worth mentioning that to solve the problems of consumption and cost, while maintaining the reach, the BLE (Bluetooth low energy) technology emerged, which allows extending the use of Bluetooth 15 to health care applications, "fitness", "beacons" (beacons), security, etc. Another interesting feature is the use of the IPSP ("Internet Protocol Support Profile") profile, which allows devices with BLE technology to discover and communicate with other devices that support this technology. This is made possible by using IPv6 packages over these Bluetooth networks .

twenty

Within all these technologies there is a subset of them that has been explicitly designed for use in sensor networks, including Z-Wave, EnOcean, NanoNET, KNX RF, LonWorks, X10, One-Net, Wireless Meter- Bus, RuBee (IEEE 1902.1), BACnet and WirelessHART.

In addition, WPAN (Wireless Personal Area Network) networks for general use have also gained a special role. Among them are ZigBee, the IEEE 802.15.4 and 6LoWPAN standard.

Currently the convergence of the sensor systems is going towards the use of the IP protocol to the end devices (“end-to-end” IP). Another important aspect for the adoption of technologies is that the specifications of the proprietary systems are not available for free, quite the opposite to IP-based solutions.

5

In the case of home automation systems with transducer networks, in the academic field there are different alternatives to commercially available systems. Analyzing the work, it can be concluded that the different academic solutions indicated focus on certain specific relevant aspects of home automation systems. Some focus on interoperability between standards and the consolidation of the home automation system with a security system, others on obtaining a friendly environment or interacting with mobile applications.

As for the proprietary systems mentioned above, it should be noted that they present 15 different drawbacks, since they are characterized by being closed and not very flexible systems that are currently not oriented to use Internet protocols, provide little or no interoperability between them and hinder development of transducers due to the costs associated with obtaining the specifications and having to submit to them to develop compatible products. No commercial solution based on these proprietary systems 20 is easily transferable to the concept of IoT, being necessary, if possible, the translation of these protocols to IP, with the extra cost and overhead that this would imply.

With the arrival of the IPv6 protocol, the possibility that a large number of 25 elements with their own IP coexist is a reality. Despite the Internet service providers (whose acronym in English are ISPs), they are still reluctant to make the change from IPv4 to IPv6 and to offer ranges of IP addresses to customers to make this possible. However, the use of IP in sensor networks allows a direct interaction with them, in addition to the use of widely used and tested protocols and standards

over IP allows from detection and configuration to their control and ubiquitous access. As for security, a wide range of possibilities and protocols can be used, from the use of the TLS (transport layer security) protocol for secure connections over HTTPS, to Firewalls or IDS (intrusion detection systems) in the installation. final to maximize security. Likewise, the creation of a user interface and its extension to mobile devices is simplified by using IP consistently.

As already mentioned above, although the use of Wi-Fi technology in the beginning may not seem suitable for use in a transducer network, more and more battery-dependent devices, such as smartphones or “ smartphones ”, which make intensive use of Wi-Fi connectivity. This has caused research and development in this regard to concentrate on reducing its size, cost and, above all, energy consumption. SoC’s (“System 15 on a Chip”) are now produced and marketed with Wi-Fi capabilities that can run on batteries for long periods of time, such as the GainSpan 1010SoC or ESP8266. These advances have led to the emergence of 802.11 b / g / n modules, with a very low cost and aimed at low consumption (for example 1mw standby, 750 mw maximum peak consumption in the case of ESP8266).

twenty

Therefore, both the emergence of the IPv6 protocol and the aforementioned "Internet of Things" paradigm have once again focused attention on the IEEE 802.11 standard for this type of network, specifically the 802.11s extension, which allows WLANs adopt a mesh topology (in English “mesh”) The most important manufacturers such as Qualcomm, Atheros, 25 Broadcom, Marvel or Mediatec market solutions with an available stack or 802.11s stack, and for Linux systems the stack is available ”Complete in software.

The above considerations confirm the need to develop an IP-based transducer system by deploying them for example over a Wi-Fi infrastructure, with

all the advantages that this entails: high data transfer, transmission distance, larger packet sizes, security mechanisms, IP standards, ease of adding new elements ...

5 On the other hand, it is worth mentioning that there are not many public implementations that allow the ability to confer intelligent transducers capacity for self-configuration and self-detection.

The most notable initiative is the ISO / IEC / IEEE 21451 standard, previously known as IEEE 1451. The standard aims to provide sensors with a series of mechanisms that provide desirable characteristics of an intelligent sensor such as self-identification, self-description , self-calibration, standardized data formats, etc., performing a dynamic "plug and play" of the sensors and facilitating interoperability between networks with heterogeneous technologies (for example IEEE 802.15.4, 15 6LoWPAN, Bluetooth or IEEE 802.11) Its use allows to abstract the intrinsic particularities of the software / hardware of the nodes of the sensor network, creating a series of software components at different levels of the architecture of an application so that you can use them to interact with various functionalities implemented in the sensors and in the intermediate nodes of the sensor network.

twenty

A key element of the ISO / IEC / IEEE 21451 family of standards is the specification of the TEDS (Transducer Electronic Data Sheets) information blocks. This data structure may be stored locally in a non-volatile memory of the transducer. In applications where this is not practical it is possible to use an electronic TEDS from a sensor description repository (virtual TEDS). TEDS, whose character is similar to the "datasheets" or data sheet provided by the suppliers, contains information related to the sensor, such as the manufacturer's name, sensor types, serial number, measurement range, accuracy, calibration data and Standardized data formats Among the benefits of its use should be highlighted:

5

10

fifteen

twenty

• They allow the self-identification of sensors or actuators, being able to identify or self-describe the host or the network.

• They provide long-term self-documentation: in the sensor the TEDS can store information that can be updated: sensor location, recalibration data, repair records and many maintenance related data.

• Reduce human error by automatically transferring TEDS to the network or system, thus eliminating manual sensing parameters that lead to errors.

• They facilitate the installation of field, update and maintenance of the sensors, helping to reduce the life cycle costs (total) of the sensor systems, since these tasks cannot be performed via "plug-and-play" sensors .

• Provide plug-and-play capabilities.

The architecture of an ISO / IEC / IEEE 21451 system is divided into two subcomponents:

• Network Capable Application Processor (NCAP). It is a special node of the network that performs functions of processing and channeling of communications. Its radio interface allows you to communicate with smart transducers, while offering different web services through another interface (for example Ethernet).

You can have an HTTP server through which to provide the network of sensors with access to each of the transducers through the Internet. For this it has a network interface, services of the transducer with which it is intended to carry out communication and the wireless communications module through which the transducer module is connected. When you receive a request you use the service and through the communications module send the request to the transducer module. The latter receives and manages it, and sends the response to the NCAP that finally and again through the HTTP server communicates it to the client.

5

10

• The smart transducer module. Referenced in the standards as TIM (Transducer Interface Module), STIM (Smart TIM) or WTIM (Wireless TIM). Acquires sensor signals and controls actuators. Through services, it is able to offer remote users sensor data or the possibility of operating an actuator. Communications with the rest of the network and with these remote users are carried out thanks to the embedded radio interface.

This component subdivision generates two new interfaces:

• Network Interface (NI): defines a network communication protocol for NCAP communications to the network.

• Transducer Independent Interface (TII): defines a means of communication and a protocol for the transfer of sensor information. It provides a set of read and write operations.

Components based on ISO / IEC / IEEE 21451 can be connected to a standardized physical communications medium and operate without any change in the software. Therefore, different drivers, profiles, or other software changes are not necessary to provide the basic operations of the transducers:

• TIMs from different sensor manufacturers can perform "plug-and-play" with NCAPs from a particular sensor network provider through the same communication module.

• TIMs of a manufacturer can perform "plug-and-play" with NCAPs supplied by different sensors or network distributors. Through the same communication module ISO / IEC / IEEE 21451.

• TIMs from different manufacturers can be interoperable with NCAPs from different network distributors through the same ISO / IEC / IEEE 21451 communication module.

5

• NCAPs can perform "plug-and-play" with a wide variety of TIMs through the standard 1451.x interface. An NCAP can support a wide variety of sensors or actuators.

10 Through this partitioning approach, a migration route is provided to those sensor manufacturers who want to build TIMs with their sensors but do not intend to become network providers. Similarly, it is applicable to those network distributors who do not want to become sensor manufacturers. Of course, vendors can combine both TIM and NCAP in a single module and sell it as an integrated network sensor. In this case the interface between the TIM and NCAP is hidden but the integrated sensor is compatible with ISO / IEC / IEEE 21451 at the network level.

In addition, the ISO / IEC / IEEE 21451 standard allows the implementation of new types of TEDS for proprietary solutions.

twenty

The main problem of the ISO / IEC / IEEE 21451 standard is the need for each transducer to implement the standard itself. This implies the use of more expensive transducers due to the extra need for hardware and the complexity required by the TEDS implementation. The TIM and NCAP modules must be fully implemented according to the aforementioned standard.

The complexity presented by the standard and the cost of its implementation to comply with all its functionality implies the use of a separate microcontroller or a processor for each TIM, which entails a significant increase in both the cost and consumption of

power of the plug-and-play sensors. This result is not desirable when scalable transducer networks are targeted. Due to this, to date the ISO / IEC / IEEE 21451 standard has not had a great reception as far as to functional implementations.

A variation of the TEDS 15 (Transducer Electronic Data Sheets) concept of the IEEE 1451 standard is presented in document EP2418463 A2. A memory component is proposed that is directly coupled to one of the transducers that stores the datasheet information for a Transducer in particular and also that of other transducers in the system.The system transducers are assigned a unique index and the data stored in the memory component is indexed to distinguish the data 20 corresponding to a particular transducer.

The main difference with the TEDS template formats for the different types of transducers defined by the IEEE 1451 standard is that the same template can be used to store information on multiple transducers in a single memory component, but different indexes are used to label data corresponding to particular transducers. In the standard each transducer has its memory device, and a particular memory device only stores information pertaining to that transducer, but in this document the template is still treated in the relative system

exclusively to transducers, and transducers must meet the specifications of a specific standard.

To establish the integration of non-SOA sensors in an SOA environment, the module has at least one first interface to connect at least one sensor, and a second interface to connect to the SOA network, that is, it requires at least one pair of IEEE interfaces 1451.x and a second integration into an SOA web service.

communication 108 between the control system 150 itself and a data network 113 such as the Internet. The configuration access point 110 is capable of establishing a data connection with wireless communication means of a transducer node 105.

10

The control system 150 is an element that has control over one or more transducer networks 103, 104, managed through the respective transducer nodes 102, 105. Said control can be exercised automatically by computer algorithms, by human intervention. , or through a hybrid approach, in which certain tasks are managed automatically while others require human intervention.

The transducer nodes 102, 105 are of the intelligent type or intelligent transducer nodes (Intelligent Transducer Node, ITN). The term intelligent refers to the fact that the transducer node 102, 105 respectively comprises a processing system linked to communication means or devices, and at least one transducer 103, 104 (analog or digital) preferably integrated. These communication means are configured so that they are capable of establishing a data communication 109 between each transducer node 102, 105 and the control system 150. These communication means can be of the wireless or wired type. The number of transducers 103, 104 associated with the same node of transducers 102, 105 may vary according to needs, thanks to the flexibility granted by the present invention.

The characteristics of an intelligent transducer node include, among others: self-identification, self-description, self-diagnosis, self-calibration, location self-knowledge, temporal instant self-knowledge, reliability, coordination with other nodes, processing of data, reasoning capacity, data fusion, alert notification, standardized data formats, communication protocols, standard control and network interface protocols, software and digital signal processing functions and easy installation.

Returning to the present transducer network installation 100, illustrated in Figure 1, its different components can be classified into three subsystems to control them, such as:

• Control and management subsystem 116: this subsystem is responsible for controlling and managing the rest of the subsystems. It controls and records all transducers 103, 104, obtains data from the sensors with the appropriate frequency and controls the actuators according to the user's indications, supporting the self-configuration and auto-detection procedures that can be carried out in the present invention.

• Communications subsystem 115: the function of this subsystem is to interconnect all transducers 103, 104 and transmit the necessary information between them and the control and management subsystem 116.

• Transducer subsystem 111: This subsystem groups sensors and actuators 103, 104 included in the corresponding transducer nodes 105, 102.

To facilitate understanding, these subsystems have been represented with dashed lines in the attached figure 1.

The control system 150 is responsible for centralizing the data collection and managing the requests associated with the transducer nodes of the installation 100, comprising the central server 101 and the gateway "Gateway" 107 for communications 106, 108, 109 of the network, and the configuration access point 110. It will also save the configuration of the transducer network (persistence of the configuration) and of the information of the transducer nodes 102, 105 that are part of it, and also It will act as an entry point for applications that allow user interaction with the system through a web API type user interface Another function that it fulfills is to provide such web API type interface.

10

Among the various alternatives on which to base the central server 101 of the control system 150 could be to use a personal computer, either a tower with a reduced format board, such as a "micro ATX", or a laptop. of these two options it provides a power and storage capacity much greater than 15 that required by the present installation 100, even with a cost, consumption and space requirements too large.

Therefore, another alternative is the use of a single board computer (SBC) as a central server 101, a platform that in its most basic format 20 integrates a system into a chip (in English "system on a chip ”SoC), RAM and a series of ports on a small board. Its cost is reduced, as well as its size and consumption, which facilitates the integration of the central server 101 in an electrical installation without complications, due to its low power and dissipation requirements.

25 A possible embodiment of the central server 101 would comprise the use of an SBC such as a Raspberry Pi 2 Model B, which has a quad-core ARM-Cortex A1 900 MHz processor and 1 GB of RAM. However, this model can be logically replaced by another version or model if the expert requires it.

As for the configuration access point 110, it is intended for communication of those wireless transducer nodes 105 with the control system 150 to achieve a definitive configuration of the connection or communication 109 between the transducer nodes 105 and the central server 101 of the control system 150 through the 5 "Gateway" 107. Preferably, the wireless communication of the nodes of transducers 105 through their means or communication devices is of the Wi-Fi type, however it will be evident to any expert in the matter that wireless communication can follow other types or protocols available.With this type of communication Wi-Fi can be achieved, several advantages are achieved: high data transfer, transmission distance 10, larger packet sizes, security mechanisms, IP standards, ease of adding new items, etc.

As a "Gateway" 107, a conventional "router" similar to the one that any ISP can provide with a home Internet connection is preferred, and among its 15 preferred features it supports WPA2 and the 802.11 b / g / na 2.4 GHz protocols. Concrete model that has been selected for the present preferred embodiment is a LinkSys WRT54G v2.2. The "Gateway" 107 may be any available on the market and that allows data communication between the control system 150 itself and a data network 113, for example the Internet.

twenty

The configuration access point 110 may be any available on the market and may even be incorporated into the central server 101, or its function may be performed by one of the transducer nodes 102, 105 that form the network or any other device with capabilities to function, even temporarily, as a point of configuration access; the choice may be made taking into account that a communication 114 can be established between the two elements. In a possible embodiment it may be a conventional "router" by default.

Although wireless communications will preferably be used, the present invention may also be carried out with wired connections, such as Ethernet type, between transducer nodes 102 and central server 101 of control system 150, through for example the gateway "Gateway" 107.

5

As described above, the transducer nodes 102, 105 respectively comprise a processing system, communication means, and a transducer / s 103, 104 preferably in an integrated manner.

The processing system of the transducer nodes 102, 105, is preferably a microcontroller that receives and processes the data that arrives and sends the transducer node. As an example, a microcontroller is used, which can be an ATmega328P or an ATmega32U4; The ATmega328P provides 14 digital inputs / outputs, 6 analog inputs, and has 32 KB of flash memory, 2 KB of RAM and 1 KB of EEPROM.

fifteen

In order to be able to store the information stored in the transducer node 102, 105, an exemplary division of the EEPROM microcontroller in bytes can be used in an exemplary manner as described in table 1. It should be noted that both the size and the number of fields can be vary if the implementation requires it:

The media may have wireless or wired modules. In the case of wireless, you can use a ESP8266 Wi-Fi module, which is a SoC of

relatively low cost that supports communications according to IEEE 802.11 b / g / n IPv4 protocol with WPA / WPA2 security.

As for the type of transducers 103, 104, they can be used depending on the particular needs of each case. By way of example, the following can be cited:

- Sensors: temperature and humidity sensor, lighting sensor and a presence sensor.

- Regarding actuators: a relay, and lighting intensity controller

10 based for example on a TRIAC.

The person skilled in the art may modify the aforementioned list of sensors and actuators according to the requirements of the installation, so the list cannot be considered limiting.

fifteen

An advantageous feature of the present invention resides in the fact that procedures are followed to auto-configure the wireless transducer nodes in a wireless network, and auto-detect the wired transducer nodes 102 or wireless 105 to the rest of the installation 100 (other transducer nodes and control system 150). 20 An example will be followed for description of wireless transducer nodes 105, in which an exemplary TCP / IP protocol is used, in other alternatives the use for example of UDP or other protocols is not ruled out.

In the first place, the self-configuration of the access to the network by the 25 nodes of wireless transducers 105 will proceed. Once the transducer node 105 is started, the finite state machine (FSM) is started.

Next, the transducer node 105 is connected to the configuration access point 110 of the control system 150. The control system 150 has a point

configuration access 110 with an SSID (network identifier) and a default password (of the configuration network). Any wireless transducer node 105 may be connected through this configuration access point 110, since they may have the SSID (network identifier) and the default password of the wireless configuration network, for example in the EEPROM of the The microcontroller of the processing system may find the SSID (network identifier) and the configuration network password known by default.

The control system 150 starts, for example, a TCP server, to listen to a configuration request message from the transducer node 105. The transducer node then issues a message requesting the configuration of definitive access to the control system 150. Subsequently, the Transducer node 105 is waiting for a response to the final parameters of the network access configuration. Then the control system 150 sends a definitive access configuration to the node of 15 transducers 105, which is written / stored in the memory, for example non-volatile, of the node of transducers 105, and more specifically the processing system through of the WFTU. At that time the transducer node 105 is restarted and connected to the "Gateway" gateway 107 using the definitive access configuration received.

20 Alternatively, the central server 101 of the control system 150 can automatically send the final access configuration parameters at the time the connection is established between the transducer node 105 and the configuration access point 110. That is , in this alternative it would not be necessary for the transducer node 105 to request the aforementioned definitive access configuration, to the control system 150.

The configuration data of definitive access to the wireless network preferably comprise the following (definitive) data, however the amount of the data may change depending on the particular needs of each case:

- SSID data;

- Wireless network password;

- Unique network identification data (for example IP);

5 - Subnet mask;

- Gateway;

- DNS server.

With these steps, the self-configuration of the intelligent transducer node 105 10 is achieved in an installation 100 with information exchange via wireless means.

In the case of a wired transducer node 102, several possibilities for accessing the transducer network, such as a unique identifier in the network, such as an IP, can be considered. In a first possibility, the transducer node 102 also accesses the configuration network, similar to what happens in the example for wireless transducer nodes 105. Another possibility is to manually adapt the identifier in the network by a user. In another possibility, the DHCP protocol may be followed for the assignment of IP addresses.

20 In order to achieve the self-detection of the intelligent transducer node 102, 105 whether wireless or wired in the network, a message announcing its presence to a control system 150 is emitted by the transducer node 102, 105. through "Gateway" 107 (if the communication is wireless, it will be done following the definitive access configuration achieved in the self-configuration procedure described above 25). Subsequently, the presence announcement message is received by part of the control system 150. After a waiting period that may be predetermined, the control system 150 (particularly the central server 101) issues a message requesting that the transducer node 102, 105 request an ID to register it in the network, and the transducer node 102, 105 issues said ID to the system of

control 150. The ID identifier preferably comprises at least the type of transducer node, the serial number of the transducer node and the version of the transducer node.

5 Control system 150 searches for said ID identifier in a repository of data structures, either local and / or remote. The data you can use can be the type of transducer node and the serial number as a search index. In the event that the ID identifier of the transducer node is located in the data structure repository, said transducer node 102, 10 105 is registered by the control system 150 together with a corresponding unique IP network identifier that he owns at that time and

a data structure of the transducer node. In addition, the time (time stamp or time stamp) at which the transducer node 102, 105 in question is added to the network can also be recorded.

15 To facilitate the access, communication and interpretation of the data handled by each of the transducer nodes 102, 105, the aforementioned data structures that encapsulate all this information are used. These structures are based on the idea of storing all the necessary information to access the data of the sensors and actuators, process them and interpret them. These data structures (of information) can be called ITEs (Intelligent Transducer Enablers), since they contain all the information to access the values of the transducer node 102, 105, interact with their transducers and interpret the information they can send or Receive the transducers. Likewise, they store the identification data of the node type of transducers involved in the auto-configuration and auto-detection processes. This information is stored in a data format such as JSON or XML, so that it can be easily accessed through "parsers". The data structures also describe units, maximum and minimum values, precision, resolution or other parameters necessary to understand the information transmitted to the user of the respective transducers.

The above steps summarize the simplified case, in which any node of transducers 102, 105 is added without the need for any type of confirmation. There is the possibility of configuring the system so that confirmation is required upon the addition of a transducer node to the network. Each transducer node 102, 105 has an ID identifier, and it can also have a MAC address associated with the user interface that the control system 150 has to communicate. Therefore, three mechanisms or operations are defined in the present invention: normal operation (simplified case that does not require confirmation), dynamic request and prior registration of identifiers; These last two are described below:

10

- Dynamic request: at the moment when the control system 150 receives a configuration request message or the transducer node 105 is connected to the configuration access point 110 (i.e., during self-configuration), or a Announcement message (that is, during auto-detection), sends a message from

15 confirmation request to all customers-users who may be making

use of the API type interface. In case there is none, the request is stored and displayed on the client's next connection. The message identifies, for example, the ID identifier and the MAC address (alternatively any other name or identifier that allows identifying a node of

20 concrete transducers uniquely) of the transducer node 102, 105, so

that the user can easily verify that the request corresponds to the transducer node 102, 105 that he is trying to add to the installation 100. At the time the positive confirmation is received, the process proceeds normally.

25

- Prior registration of ID identifiers: if you want to add a plurality of transducer nodes to the network, they can be previously registered in the system by a combination of ID and MAC (or any other name or identifier that allows you to identify a node of unique transducers). In the process of self-

configuration, the control system 150 before a configuration or connection request message through the configuration access point 110 by the transducer node 102, 105, verifies that the ID and MAC of the transducer node from which the request comes or connection is previously registered. 5 In that case send the final access configuration.

In the self-detection process the check is repeated either with dynamic request or with prior registration, and in case of being positive the control system 150 registers the transducer node 102, 105 and makes it available on the network (such as already mentioned 10 above).

As already mentioned, the identifier ID of the transducer node comprises at least the type of transducer node, the serial number of the transducer node and the version of the transducer node, which appear in the corresponding cells of Table 1. With 15 the division of EEPROM memory in Table 1 there are 16777216 possibilities for the node type, 4294967296 for the serial number and 256 for the version. In addition, 8 bits are available to establish status flags, which will be used to determine, for example, whether or not the transducer nodes have obtained the configuration of definitive access to the network, nodes of transducers and other future uses.

twenty

In the event that new transducers are incorporated into existing transducer nodes, the version of transducer node 102, 105 will have to be adapted, for example manually through the API interface.

25 The API interface facilitates, once the transducer nodes 102, 105 are registered by the control system 150, a mechanism that allows us to make the requests supported by each of them, and even recalibrate them. The aforementioned API interface allows access to sensors and actuators for example from a remote position. At the moment

preferred embodiment communication will be established at HTTP level, although other types may be used such as HTTPs, CoAP, etc ...

Once the transducer nodes 102, 105 have been registered, a user may receive from the control system 150, the unique network identifier data and the data structure associated with a transducer node and its respective transducers. Said data will be displayed on an electronic user device 112 via a user interface. However, depending on the particular needs of each case, the user will be able to access the said API interface directly through the central server 101, so that in that case an access to a data network 113 would not be necessary.

In addition, the control system 150 can also send the data of a transducer, to the electronic user device 112 via the user API interface, the data may be:

fifteen

- Type of transducer;

- Number of inputs / outputs;

- Current value;

- Rate of soda.

twenty

Reciprocally, the control system 150 can subsequently receive action orders on a transducer 103, 104, from the electronic user device 112 via the user interface, since the associated transducer nodes 102, 105 are already registered in the net.

25

All interaction between the control system 150 and a user explained in this preferred description is done through the API user interface. However, the aforementioned interaction can also be carried out against other "non-human" systems (ie M2M, "machine to machine")

of carrying the program.

In addition, the carrier means may be a transmissible carrier medium such as an electrical or optical signal that can be transmitted via electrical or optical cable or by radio or other means.
