Objectives

The well-being of people depends in part on the sense of freedom, and one aspect is certainly the possibility for people to remain at home. However, there is a need for “following” the movements and, if possible, the activity of the person. The problem is that very few home systems make it possible to have these data at a reasonable price, and at an acceptable reliability level. We offer a simple to use, reliable and energy self-sufficient person location system. People are the first “targets”, but objects could be involved.

Material and methods

The system is described and their performance analyzed in real conditions of use. The positioning algorithms are explained and the practical implementations described.

Results

First results on the activity of a person at home are presented as well as some tracks on the type of data processing that could be considered.

The simplicity of deployment is shown and the usefulness of the available data is discussed in the context of home care of an elderly person as well as the monitoring of hospital equipment.

Conclusion

Our approach provides simplicity of implementation and very high reliability in real time, without aiming for high accuracy in all cases. Conceptually taking into account the high variability of indoor radio measurements makes it possible to significantly increase the reliability of the geo-data produced. Moreover, we will mention two real deployments and the associated performances obtained, carried out in order to follow the behavior of an old autonomous man living alone at home, and in another hand to follow the stretchers of the emergency department of a French hospital.

地理数据生产系统

目标

人们的福祉部分取决于自由感，一方面当然是人们留在家中的可能性。但是，需要“跟随”人的动作，如果可能的话，还需要“跟随”人的活动。问题是很少有家庭系统能够以合理的价格和可接受的可靠性水平获得这些数据。我们提供简单易用、可靠且能源自给自足的人员定位系统。人是第一个“目标”，但可能涉及物体。

材料与方法

描述了该系统并分析了它们在实际使用条件下的性能。解释了定位算法并描述了实际实现。

结果

介绍了关于一个人在家活动的初步结果，以及一些可以考虑的数据处理类型的轨迹。

展示了部署的简单性，并在老年人的家庭护理和医院设备监控的背景下讨论了可用数据的有用性。

结论

我们的方法提供了简单的实施和非常高的实时可靠性，而不是在所有情况下都追求高精度。从概念上考虑室内无线电测量的高度可变性可以显着提高所生成地理数据的可靠性。此外，我们将提到两个真实的部署和获得的相关性能，执行这些部署是为了跟踪一位独自住在家里的自主老人的行为，另一只手跟踪法国医院急诊室的担架。
