Abstract

standalone electronic presence tags for improvements arising from the use of standalone presence tags, which do not require a power or communication network and work individually, we have tags with circuits for detecting and recording proximity to tags and supplying our own long-term energy duration 1.0. thus, any body in motion (people, land vehicles, aircraft) or fixed (doors, buildings, fences, trees) can have their tags and they will register the encounter in the passage between them 2.0.

Description

Autonomous Electronic Presence Tags

01. The present invention relates to autonomous electronic tags for presence detection, capable of communicating with each other, functioning both without an electrical network and without an external communication network.

02. Current tag solutions based on RFID (radio frequency identification) or other protocols, demand robust readers that generate the electromagnetic field necessary for the tag to be activated and transmit its data. Current systems operate at Low Frequency (30KHz to 500KHz) or High Frequency (850MHz to 950MHz and 2.4GHz to 2.5GHz).

03. In this way RFID solutions are characterized by a simplified tag and a more sophisticated, larger reader, which has an energy source capable of activating the tag at a certain distance.

04. Current electronic label solutions, therefore, are based on a simpler label, with low energy consumption combined with a more sophisticated reader and that demands a more powerful energy solution. The tags do not communicate with each other, all are read by a specific reader.

05. For demands of control and operational management where the tags can exchange information with each other when they approach, in an autonomous and independent way, they can store in themselves the occurrences of these approaches and at some point can transmit the content of their memories, the current solutions are unsatisfactory.

06. The invention has the basic task of creating sensory electronic presence tags that communicate with each other, both being small, with low energy consumption, autonomous and with no demand for reading very close or directed manually with a reader, thus eliminating the need that one side of the process (sender or reader) is in a powerful network of energy or data transmission.

07. This task is solved according to the characterization part of the claim 1. According to this, each label has a transmitter and receiver module, memory that records the moment of the encounter between two or more labels, and its own energy source. In a second future moment, when the tag enters a communication source, it transmits its data to it, which in turn can send the data to the Internet or any computer network.

08. For this invention of a communication solution between these tags to work, it is necessary to solve logical and physical problems (circuits) by defining a specific communication protocol between them, as well as defining correct radio frequency bands.

09. The invention has the advantage of solving efficiently and non-trivially the demand for electronic tags that record the occurrence of encounters between tags even in remote places, without power or external data networks and in a dynamic or random way (not pre- determined).

10. The invention also has the advantage of working for long periods (greater than 2 years) in a completely autonomous and independent way, without a centralized organization.

11. The invention consists of modules on each label called, a) Transmitter, which is an electronic circuit that emits a signal from the label, b) Receiver that receives signals from nearby detected labels, c) Recorder, which records the encounter, the proximity of some tag, with date, time and ID (identifier) of the tag found and d) Communicator, which transfers the data recorded in the tag's memory with all records of encounters with other tags and e) Concentrator, module that receives the module data Communicator of each label and stores and / or transfers this data to external sources (computer or network).

12. The minimum protocol for data to be shared is Tag ID, Date and Time of the connection, encounter or proximity to other tag (s).

13. All labels are therefore identical, with all modules installed. When they are close to other similar tags, presence information (date, time and identifier of the other tag) is exchanged and stored on the tag itself. When it approaches a Concentrator, it downloads its memory information by sending its data to this Concentrator, which in turn sends it to the Internet or any computer network.

14. Next, the invention will be described in greater detail with the aid of examples of presentation presented in Figures.

15. It shows:

16. In figure 1, a general scheme of labels installed at fixed points 1.1 or on movable bodies 1.2 that exchange information between themselves when close and the Concentrator module that receives the information from the labels when close and transmits to the Internet or Computers 1.3.

17. In figure 2, an individual label with its radio frequency modules that communicates with other labels and with Concentrator 2.1, internal clock to record the date and time of meetings with other labels 2.2, memory to store the records of these meetings until pass this information on to Concentrator 2.3 and the local battery module to be autonomous from external energy for at least 2 years 2.4. The Concentrator 3 module also has a radio frequency module 3.1, also its own memory that accumulates records of tags that approached it 3.2 and a USB 3.3 module that connected to a computer transmits the historical record stored against tags to the computer or Internet network.

18. Results obtained in the field resulting from the implementation of the invention demonstrate that the use of electronic presence sensory tags solve control and management problems not possible with other solutions. Especially in cases where specific fixed or mobile readers cannot be installed, where power and data networks are not available or discretion and anonymity are still required at the time of reading.
