Proximity detection device
The invention relates to a device (D) for detecting the proximity of a part (M) of a user's body and/or of a portable user device (200), intended to be housed on board a motor vehicle (V), comprising: a) a near field communication antenna (A1) configured to transmit and receive signals at a high resonant frequency selected between 3 and 30 MHz, the antenna comprises at least one winding (E1, E2, E3) extending continuously in the form of a set of bars (O1, O2... Oi, N1, N2... Ni) such that the bars have a variable capacitance connected to the antenna and the antenna is capable of generating a capacitance change in response to the approach of a part of the user's body, b) a measurement means (M2) for measuring the capacitance of the antenna in response to the approach of a part of the user's body, and measuring means for measuring a change in impedance or frequency of the antenna by electromagnetically coupling with the antenna, the measuring means having a series resonance frequency at the selected high resonance frequency and being capable of detecting proximity of the portable user device or proximity of a part of the user's body.
本发明涉及一种用于检测用户身体的一部分(M)和/或便携式用户设备(200)的接近的装置(D)，该装置旨在车载容纳在机动车辆(V)上，该装置包括：a)近场通信天线(A1)，该近场通信天线被配置成以在3与30MHz之间选择的高谐振频率传输并接收信号，所述天线包括至少一个绕组(E1，E2，E3)，该至少一个绕组以一组棒(O1，O2……Oi，N1，N2……Ni)的形式连续地延伸，使得所述棒具有连接至所述天线的可变电容并且所述天线能够响应于用户身体的一部分的接近来产生电容变化，b)测量器件(M2)，该测量器件用于通过与所述天线电磁耦合来测量所述天线的阻抗的变化或频率的变化，测量器件在所选择的高谐振频率下具有串联谐振频率并且能够检测便携式用户设备的接近或用户身体的一部分的接近。
