This project consists of developing a simple device in order to count pulses and sending a report to a backend using NB-IoT. The main requirements of the whole system are: NB-IoT communication. The device has to be as small as possible. The device has to be able of sending 2 sessions during 6 months everyday, so the total number of sending sessions are 365, using a lithium primary battery non-rechargeable.
This project consists of developing a simple device in order to count pulses and sending a report to a backend using Sigfox. The main requirements of the whole system are: Sigfox communication. The device has to be as small as possible. The device has to be able of sending 2 sessions during 2 years everyday, so the total number of sending sessions is 1460, using a lithium primary battery non-rechargeable.
The goal of this project is to develop the hardware to be able to detect possible anomalies in offshore windmills. The HW platform consists of 4 ADCs (Analog Digital Converters) with phantom power supply using a raspberry pi 3B. The SO is an embedded Linux system generated with buildroot. These ADCs are connected to sensors that are able to make a precise measurement of the bearing vibrations, in order to analyze that data with algorithms, to make an estimate the need to be replaced.
This project consists of developing an industrial controller with the following features: 10 relay outputs. 6 optocoupled inputs. 1 RS-485/RS422 port (configurable). 4 Wiegand ports for NFC card reading. The HW platform is based on a Raspberry Pi 3B with PLP (Power Loss Protection) in order to create a robust platform against voltage drops avoiding corruption in the file system. The SO is an embedded Linux system generated with buildroot.
This project belongs to a IBEROEKA project and it was developed in two different phases. Phase I: Proof Of Concept The goal of this phase is manufacturing an HW platform in a fast way, using open hardware in order to validate that an image sensor NIR (Near InfraRed) is able to extract useful information when the image is illuminated with LEDs with different wavelengths. The open hardware selected is the raspberry pi 3B with an optimized embedded Linux system generated by buildroot.
The goal of this project is to develop the whole electronic system for controlling an ROV, as well as the embedded system. The system is equipped with 6 thrusters, an IMU (Inertial Measurement Unit), a pressure sensor, 2 temperature sensor, 6 ADCs (Analogue Digital Converters) in order to get the thrusters speed and 6 DACs (Digital Analogue Converters) to set the speed thrusters. The system has to be able to perform the acquisition of 6 analogue digital using 6 ADCs (in order to know the thruster speed), the IMU data (in order to know the ROV position), the pressure and temperature to send the data by UDP to an external unit.
Limva project is based in an OMAP3 platform, OMAP3730 by Texas Instrument with an optimized embedded Linux system generated by buildroot. The goal of this device is to make an image acquisition for further processing. The MT9P031 by Aptina (now On Semiconductor) is used for image acquisition. This device is portable with a lithium-ion battery rechargeable. Other platform features: PMIC (Power Management Integrated Circuit) TPS65950 by Texas Instruments. NOR Flash S29NS512P by Spansion (new Cypress).
The v2 is designed and optimized with several improvements. It is based on the same microprocessor the i.MX27 by Freescale. In this v2 there is only the possibility of digital video acquisition, with an image acquisition sensor by OmniVision OV7675 and for the audio system acquisition is used an electret microphone and one speaker of 500m Watts with the Audio Code WM8974 by Cirrus Logic. One of the new main features is PoE(Power Over Ethernet) support.
This Video/Audio IP device was designed with the goal to be used in the surveillance and access control market. The main processor is a i.MX27 by Freescale and is based on an optimized embedded Linux system generated by buildroot. There are two possibilities of video acquisition: analogue video acquisition using a video code TVP5151 by Texas Instruments or digital video acquisition using an image acquisition sensor by OmniVision OV7670. For the audio system acquisition is used an electret microphone and 2 speakers of 500m Watts with the Audio Code TLV320AIC3254 and the audio amplifier TPS2012 by Texas Instruments.
The goal of this project was to develop the automation of a powder recycling plant. I used a PLC(Programmable Logic Controller) of SIEMENS, more specifically one of the family S7-300. The challenge of this project was to be able to manage all the different devices which take part in the recycling process, like for example valves, flow meters, temperature measurement, pressure measurement, level measurement, pumps, filter press, variable speed drives and so on.
