| Abstract: | The reliability technology is the key of the monitoring system's realization in coalfield fire zone.Time synchronization and the data transmission from the monitoring node to the center are two center taches of reliability.Most of the current time synchronization algorithms are computationally intensive and ask too much of hardware.A low power cost time synchronization algorithm based on error correction via linear fitting and local clock self-correction is proposed,which is simple and easy to implement on ... |
