摘要
近年来,无线传感器网络逐渐被应用在温室控制系统中。现有的温室中传感器节点位置的确定大都是实施人工对节点进行定位,既浪费时间又浪费人力。为了改善这种情况,着重讨论了温室中传感器节点布置后进行自动定位的方法,应用了基于接收信号强度差的定位方法。这种测距的定位方法精度较高,且成本较低,适合应用于温室控制中。
In recent years, the wireless sensor networks have been gradually applied in the greenhouse control system. In the existing greenhouse, the sensor nodes' localization is mostly implements by the man - power. This is a waste of time and a waste of manpower. In order to improve the situation, we are focusing on the sensor node' s localization by itself in the greenhouse. In this article we will apply a localization method based on the RSSI. This range free localization method's precision is high, and the cost is low, and it is applied to the greenhouse control system.
