Activities of the latin american center for open technologies

The project RFIDMonitor aims to provide a generic way of monitoring data from “collection points”.  These collection points can be understood as, for example, electronic turnstiles, barcode readers, RFID identifiers, temperature sensors, etc.
The received data can represent, for example, the badge number of an employee, an identifier of an animal in the jungle, the values ​​of a seismic sensor, among others. These are sent to a central server through automated or semi-automated techniques. At the server, the data is stored in a centralized database that can provide the reading and manipulation of it through a software interface. Thus, other software such as web applications, mobile devices and applications in server applications can interact with the data manipulating them and presenting them as information to end users, such as biologists, researchers, engineers, among others.
Technical objective
Offer a smart way to manipulate data and provide a “point of data collection”, storing them in a central “server” so that data structures are generic, and can be used by other systems.
It is understood by “point of data collection” as the device that receive information and through input devices and is able to transmit data using the network.
It is understood by “central server”: a central, working on a server computer that receives data sent from collection points, stores the data and makes them available for manipulation by other authorized software.

The first usage of the RFIDMonitor was in the context of monitoring the fish stream in the Piracema channel located in ITAIPU, please visit https://www.itaipu.gov.br/meioambiente/canal-da-piracema for more details. The Piracema’s fish monitoring was an issue back then that led to the need of this project. Due to the specific purpose of the project at that time, the development of  the application required:

The creation of new modules so it may be possible to use the existing reading equipments;
The implementation of a data structure considering the informations that biologists expect the system to read;
A web application with an interface for server interaction so that users can get access to stored data, as well as searching, filtering and exporting data. Regardless of the default data structure, users can also register new data structure for merging purpose. The web application allows other types of iteration than those mentioned so far.
