Telemetry system designe for electric vehicles

Telemetry systems are used to remotely control and/or monitor a system as wired or wireless. In this study, a control algorithm is designed to prevent data loss for RF based telemetry system. In the designed algorithm, in case of RF transmision a partial or complete blockage, there is an automatic frequency shifting process that can switch to a different carrier frequency. A micro-controller-based test platform designed to test the purposed algorithm is carried out and RF modems are used in the test platform. The results obtained from the tests show that the data which could not sent in blockage of RF transmision saved in eeprom memory and the data can be re sent to center telemetry unit after the removed blockage.
