Telemetry is a system that allows the measurement and transmission of data from various vehicle systems to a control center in real time.
This data can include information on speed, vehicle position, temperature, pressure, or even particulate emission levels, among others. In the case of TMB, this system has become an essential tool for maintaining its bus fleet in the best possible condition.
Data collection with the telemetry system
To collect telemetry data, TMB employs a number of sensors found in various systems on its buses. These sensors measure a wide range of parameters, such as speed, temperature and pressure.
All this information is transmitted through a CAN bus, which allows communication between all devices inside the vehicle. Relevant data is collected by the in-vehicle system and sent via 4G to a centralized system.
In this control center, data can be visualized in real time and stored for later analysis. This information provides TMB with an in-depth view of the performance and operation of each of its buses.
Telemetry to avoid breakdowns
Telemetry technology is revolutionizing the management of public transport fleets in Barcelona, with remarkable results in the prevention of breakdowns and operational efficiency.
First, telemetry allows constant monitoring of the vehicles. Sensors and communication systems collect real-time data on fleet performance.
This information is crucial to identify areas of improvement and adjustments needed to maximize bus performance.
A highlight of this monitoring is the early detection of potential problems. Telemetry can identify anomalies in vehicle operation, such as engine overheating or excessive brake wear, allowing preventive measures to be taken before problems become costly breakdowns.
Especially in the case of electric buses, telemetry plays a key role in preventing battery failures.
The detection of abnormal battery temperatures allows anticipating potential problems and applying corrective actions in an efficient manner, avoiding costly battery replacement and ensuring the continuous operation of the vehicles.
The implementation of telemetry for vehicle monitoring is an approach towards the evolution from preventive to more predictive maintenance.
