The distance between the reactive sensor node and the target node is estimated by using the value of RSSI, since the strength of radiation signal and the square of distance is inversely proportional. We proposed a method to derive the position of the target node based on the theory of radical center. With data from three reactive nodes, the position of target node can be analytically estimated.
我们以讯号强度指标来推估节点与被追踪物件的距离,并利用圆之根轴的几何特性,提出一个位置的估算方法,可以简单地利用三个感测节点所回传的资讯计算出被追踪物件的位置,所提出的方法即使在距离值有误差的情况下,依然能够估算出被追踪物件的唯一位置。

One was that research objects were ruleless and dishevelled. Another was that research target was reducing Ommission Error of change parcel. The Distance Discriminate Analysis was meliorated in the paper to get better recognizing effect. One was turning the question of change parcel to the question of standard land type. Another was making strict regulation. This improved Distance Discriminate Analysis is not only visual and briefness, but also easy operational.
在设计变化地块识别的判决函数时,本文针对变化地块识别工作的特殊性:1、以无规律性、无集群性的变更地块为研究对象;2、以降低变更地块的漏判率为目标,对距离判别法做了如下改良:1、将无规律、无集群性的变更地块识别问题转化为有规律、有集群性的地类识别问题;2、严格判类规则(将落入误判高发区的待测样本视为变更地块),以减少变更地块的漏判。

UDZ Series liquid level indicator of flap disassembly fast and convenient, the installation position can be arbitrary choice, free to change the direction of observation, thus instrumented great visibility; UDZ series of cost-effective liquid level was significantly higher than that used multiple sets of glass plate liquid level of cost performance; UDZ series of liquid level indicator, the sender's device, as well as the liquid level with the main transmission medium within the complete separation of the measured structural design, so that level gauge in the job has pressure (up to 320KG), toxic and inflammable conditions, with absolute safety and reliability; UDZ-3 type uses innovative design, improve the sensitivity of the sensor, and its near-zero drift FarEasTone signals and long-term stability so that it has always been at the scene consistent level instructions; sensors and the main body has a certain interval, which can be solved effectively under high-temperature liquids (up to 480 ) remote detection and control; antifrost type UDZ Series Level Gauge, are I plant the patented product (Patent No.: ZL00221022 3), guarantees that the use of cryogenic liquid level gauge is not freezing (such as liquid CO2), the effective guarantee of the level of a normal job.
UDZ系列液位计的翻板指示器拆装快捷方便,安装方位可任意选择,观察方向可随意改动,因而仪表指示的可视度很大;UDZ系列液位计的性能价格比明显高于采用多组玻璃板式液位计的性能价格比;UDZ系列液位计的指示器,发讯器、以及液位变送均与主体内被测介质完全隔离的结构设计,使液位计工作在有压(可达320KG)、有毒和易燃的工况下,具有绝对的安全性和可靠性;UDZ-3型采用了新颖设计,提高了传感器的灵敏度,其远传信号近乎零温漂和长期稳定性使其始终于现场液位指示保持一致;传感器和主体有一定的间隔,因而能有效地解决高温液体(可达480℃)远距离检测和控制;防霜型UDZ系列液位计,是我厂的专利产品(专利号:ZL00221022·3),保证了在低温液体上使用液位计不结冰(如液体CO2),有效的保证了液位计的正常工作。
