Abstract:
(EN) Disclosed are an electromagnetic field detection apparatus (10), a movable device (20) and a boundary identification system. The electromagnetic field detection apparatus (10) comprises a control unit and at least one group of electromagnetic field sensors, wherein each of the electromagnetic field sensors comprises at least two induction coils which are arranged at an included angle and are capable of carrying out detection in different directions for an magnetic field signal at any position of a working field, thus avoiding the occurrence of a magnetic field being absent, making a detection result more precise, and solving the problem in the prior art of low identification precision of a sensor with regard to a working boundary, resulting in a relatively large degree of path distortion when a device walks along a boundary line.
(FR) L'invention concerne un appareil de détection de champ électromagnétique (10), un dispositif mobile (20) et un système d'identification de limite. L'appareil de détection de champ électromagnétique (10) comprend une unité de commande et au moins un groupe de capteurs de champ électromagnétique, chacun des capteurs de champ électromagnétique comprenant au moins deux bobines d'induction qui sont agencées en formant un angle d'ouverture et peuvent effectuer une détection dans différentes directions pour un signal de champ magnétique à n'importe quelle position d'un domaine de travail, ce qui évite la survenue d'une absence de champ magnétique, rend un résultat de détection plus précis, et résout le problème, dans l'état de la technique, de faible précision d'identification d'un capteur en ce qui concerne une limite de travail, entraînant un degré relativement important de distorsion de trajet lorsqu'un dispositif marche le long d'une ligne de limite.
(ZH) 一种电磁场检测装置(10)、可移动设备(20)及边界识别系统。该电磁场检测装置(10),包括控制单元与至少一组电磁场传感器,该电磁场传感器包括至少两个呈一夹角排布的电感线圈,可以对工作场地上任何位置的磁场信号进行不同方向的检测,避免了磁场缺失的情况发生,检测结果更加精确,解决了现有技术中传感器对工作边界的识别精度不高,导致设备沿边界线行走时路径歪曲幅度较大的问题。
