Object of the invention

5 The generic concept of smart city or “Smart City” in English is known as a modern and sustainable city where the latest technologies and communications systems are applied to the entire urban fabric, achieving intelligent and efficient city management and enabling Direct and immediate access to information to citizens, administration and companies.

10 The device object of this invention, called “iZONO” (Intelligent Zoned Open Node), allows different city services to be connected in a single zonal network such as: points of light, led traffic lights, environmental sensors, actuators, meters, street furniture etc., with Control Centers and / or data platforms (Open Data, big data), achieving with this single device a convergence of electronic elements and communications networks,

15 simplifying components and improving management and operation. Complying with regulations, standards and being an open system.

Background of the invention

There are currently multiple independent smart device solutions for the control of Smart City facilities.

20 There are also different communication systems to access your information such as, control cable, fiber optic, carrier wave, radio frequency, etc.

On the other hand the irruption of the led lamp has revolutionized the lighting improving its efficiency and facilitating its control.

Led lamps, sensors and other services, for their operation they need auxiliary equipment that facilitates the appropriate voltage and intensity, these equipment are called Drivers.

Detailed statement of a preferred embodiment

With reference to Figure 1, it can be seen that the device "iZON" is a device that integrates in a single envelope 1, a plurality of modules: communications 3, control 4, and power 5. The input power 6 allows powering the device to various levels of AC voltage and the power output 8 allows one to three outputs in continuous and with different voltages and power. Input 9 allows sensors to be connected as presence detectors.

Figure 2 shows the aforementioned communication module 2, which comprises two communication interfaces 11, 13, compatible with a transceiver 14, a Radio Frequency (RF) element or a carrier wave through the same power cable (OP ) by which the communication module 3 communicates, externally with a remote control center and / or platform (open data), and internally, through the transceiver 14, to the control module 4 when an order or event is received from control, management or alarm.

Figure 3 shows the control module 4 comprising a Central Unit (microprocessor) 50 that communicates with peripheral elements such as power sensors 40, a Calendar Clock 60, a read and write memory 80, a GPS 90, a temperature sensor 100 and with the communication module 3. When the Central Unit 50 considers it appropriate according to the parameters obtained, it gives the desired regulation order to the Power Module 5.

Figure 4 shows the power module 5 for small powers. This module 5 mainly comprises a step of correction of the power factor 51 to reduce the impact of the reactive energy that is generated, to obtain galvanic isolation by means of an indirect converter. It also has a low voltage output, filtered, and constant. The power module also comprises a low power auxiliary power supply 52 to power the control and other internal stages of the driver, some of these outputs have galvanic isolation; a constant current source 53 by which the value of the current to be circulated through the LEDs is previously adjusted, with their respective protections; a module of LED’s 54 that will depend on the needs, will be of low power either in configuration with discrete LED’s or integrated solutions of ARRAY COB type; a control module 55 for managing the brightness level. The output of this stage will be a PWM signal or by analog control, which governs the intensity level of the constant current source. The input signal may be wireless, KNX type control bus, DALI or PLC [Power Line Communications].

Figure 5 shows the power module 5 for intermediate powers. In this case, the module comprises a step of correction of the power factor 61 to reduce the impact of the reactive energy that is generated, in this case it is a previous converter without galvanic isolation that raises the rectified input voltage to a high continuous voltage level. Likewise, it also comprises a direct current / direct current converter 62 that reduces the high input voltage at a lower and manageable voltage with galvanic isolation, the topology of this converter can be the indirect converter or a resonant bridge means to obtain � high efficiency. An auxiliary power supply 63, of low power, feeds the control and other internal stages of the driver, some of these outputs have galvanic isolation. A constant current source 64 previously adjusts the value of the current to be circulated through the LED’s, with their respective protections, and a

LED module, which will depend on the needs, will be of low power either in configuration with discrete LEDs or integrated solutions of type ARRAY COB 65. Finally, it also includes a control module 66, for the management of the brightness level . The output of this stage will be a PWM signal or by analogue control that governs the intensity level of the constant current source. The input signal may be wireless, control bus type KNX, DALI or PLC [Power Line Communications]

In order to verify the correct operation of the proposed device, a real counter has been carried out that includes the implementation of a network using a market gateway, to create 3 zonal networks and 15 “iZONO” devices (5 “iZONO” devices for each zonal network).
