A METHOD IN A WIRELESS PROCESS CONTROL SYSTEM FOR REDUCING POWER CONSUMPTION, AND A CONTROLLER AND COMPUTER PROGRAM PRODUCTS |
摘要 |
A method in a wireless process control system for reducing power consumption of a sensor node of the wireless process control system. The wireless process control system further includes a controller in wireless communication with the sensor node wherein the sensor node is in a sleep mode. The method includes the steps of: predicting based on an error signal, when sensor measurement data is needed from the sensor node and determining an instant of time for communication between the controller and the sensor node based thereon; and the sensor node re-entering the sleep mode. The invention also relates to computer program products and a controller. |
