无线过程控制系统中用于降低功耗的方法、控制器和计算机程序产品
Abstract:
本发明涉及一种无线过程控制系统1中用于降低无线过程控制系统1的传感器节点S1、S2、…、Si、…、Sn的功耗的方法20。该无线过程控制系统1还包括与传感器节点S1、S2、…、Si、…、Sn进行无线通信的控制器2，其中传感器节点处于休眠模式。方法20包括步骤：基于误差信号预测21何时需要来自传感器节点S1、S2、…、Si、…、Sn的传感器测量数据并且基于其确定用于在控制器2和传感器节点S1、S2、…、Si、…、Sn之间进行通信的时刻；以及传感器节点S1、S2、…、Si、…、Sn重新进入休眠模式。本发明还涉及计算机程序产品和控制器。
Abstract(English):

The invention relates to a method 20 in a wireless process control system 1 for reducing power consumption of a sensor node S1, S2,..., Si,..., Sn of the wireless process control system 1. The wireless process control system 1 further comprises a controller 2 in wireless communication with the sensor node S1, S2,..., Si,..., Sn, wherein the sensor node is in a sleep mode. The method 20 comprises the steps of: predicting 21 based on an error signal, when sensor measurement data is needed from the sensor node S1, S2,..., Si,..., Sn and determining an instant of time for communication between the controller 2 and the sensor node S1, S2,..., Si,..., Sn based thereon; and the sensor node S1, S2,..., Si,..., Sn re-entering the sleep mode. The invention also relates to computer program products and a controller.
