Telemetry - definition
Telemetry is a technology for remotely measuring and transmitting data on physical, chemical or operational parameters of objects, devices and systems, used in engineering, industrial automation, energy, transport and scientific research. It is based on the collection of information from sensors and transducers, its processing and wireless or wired transmission to control centres, databases or analysis systems in real time.
The functioning of telemetry systems is based on the interaction of three main components: measurement units equipped with sensors, signal processing systems and data transmission systems. Sensors measure physical quantities such as temperature, pressure, speed, electrical voltage or radiation levels, and then convert them into electrical, digital or radio signals. Microprocessor systems perform conversion and data filtering, eliminating noise and optimising the flow of information according to system requirements.
Data transmission in telemetry systems is carried out using a variety of communication technologies, including radio waves, GSM/LTE/5G cellular networks, satellite systems, IoT (Internet of Things) communications, LPWAN (Low Power Wide Area Network) networks and wired transmission protocols such as Ethernet, RS-485 or fibre optics. Depending on the application, telemetry can use one-way transmission, which involves sending data to a receiver, or two-way communication, which allows interaction and control of devices at a distance.
Telemetry applications include industrial process monitoring, management of power grids, air and rail traffic control, vehicle diagnostic systems and space exploration, where telemetry allows data to be sent from spacecraft and satellites to operational centres on Earth. In the medical sector, it is used in telemetry systems to monitor patients' vital signs and transmit information to diagnostic units, enabling remote health monitoring.
Advanced telemetry systems integrate artificial intelligence algorithms and machine learning, which analyse large amounts of data in real time, predict failures and optimise device performance. The implementation of cloud technologies allows global access to and analysis of telemetry data in predictive maintenance systems. Today's telemetry standards include communication protocols with low power consumption and high fault tolerance, enabling long-term operation of equipment in hard-to-reach locations such as undersea industrial installations, drones or remote weather stations.
