Description
一种传感器及应用该传感器的通信装置及电子产品 技术领域 Sensor and communication device and electronic product using the same
本发明涉及一种传感器， 尤指一种基于磁场感应的通信传感器， 本发 明还涉及该传感器的应用。 背景技术 The present invention relates to a sensor, and more particularly to a communication sensor based on magnetic field induction, and to the application of the sensor. Background technique
当今社会， 无线通信技术越来越广泛地得以应用， 如通过射频 （RF) 来对信号进行传送和接收的技术， 包括 ί见有的无线通信设备， 如手机等大 都是通过射频技术 （RF) 来进行无线信号的传送及接收。 但是， RF技术需 要复杂的通信线路以及充分的电流供应， 其结构复杂， 增加了通信设备的 体积与重量。 In today's society, wireless communication technologies are becoming more and more widely used, such as the technology of transmitting and receiving signals through radio frequency (RF), including wireless communication devices such as mobile phones, which are mostly through radio frequency technology (RF). To transmit and receive wireless signals. However, RF technology requires complex communication lines and sufficient current supply, and its structure is complicated, increasing the size and weight of communication equipment.
另一方面， RF具有的衰减期小的特性，保证其可做到较长距离的传送。 正因为其传送距离长， 在传送或接收过程中容易受到其他电磁设备对其带 宽的分享及干扰， 并且也会由此引出通信中信息被他人截获而产生通信安 全威胁的问题。 在实际的应用中， 尤其是在室内， 经常会出现因为其他设 备的干扰而带来的信号减弱或阻塞； 并且， 本领域的技术人员熟知， 人体 也会明显的使 RF信号受到衰减及反射。而由于上述因素影响而丢失的数据 信号， 需要更多的能量以及带宽来对其进行恢复。 On the other hand, RF has a small attenuation period, which ensures that it can be transmitted over a longer distance. Because of its long transmission distance, it is easy to be shared and interfered with by other electromagnetic devices during transmission or reception, and it also leads to the problem that communication information is intercepted by others to generate communication security threats. In practical applications, especially indoors, signal attenuation or blockage due to interference from other devices often occurs; and, as is well known to those skilled in the art, the human body also significantly attenuates and reflects RF signals. The data signal lost due to the above factors requires more energy and bandwidth to recover it.
由于目前蓝牙， Wi-Fi等设备的用户越来越多， 使得 2. 4GHz 的 RF带 宽分享变的更为拥挤。 而由此引起的数据丢失即使再次提供更多的能量也 难以恢复， 甚至只会使其更为混乱。 Due to the increasing number of users of Bluetooth, Wi-Fi and other devices, the 2. 4GHz RF bandwidth sharing becomes more crowded. The resulting data loss, even if it provides more energy, is difficult to recover, or even only makes it more confusing.
与 RF技术相比， 磁场通信具有较大的衰减期， 因此其传送范围较短， 大约为 1. 5至 2米。 但对于短距离通信来说， 较大的衰减期使短距禽通信 具有相当安全和保秘性高的优势。 利用磁场通信时， 会在短距离内形成一 致密的 "通信圈" ， 即使在多用户同时通信的情况下， 也仅有很少的带宽 分享， 每个用户都会在一定的空间内拥有独立完整的带宽而不用与他人分 享。 即使偶尔会有很少量的 "重叠" 情况出现， 也可以通过简单的频分技 术来解决。 而且， 磁场也几乎不受周围的金属， 导体或人体的干扰影响。 Compared with RF technology, magnetic field communication has a large attenuation period, so its transmission range is short, about 1.5 to 2 meters. However, for short-range communication, the large attenuation period makes short-distance avian communication quite safe and highly secretive. When using magnetic field communication, a dense "communication circle" will be formed in a short distance. Even in the case of simultaneous communication by multiple users, there is only a small amount of bandwidth sharing, and each user will have independent and complete space in a certain space. Bandwidth without sharing it with others. Even occasionally there will be a small amount of "overlapping" situations that can be solved with simple frequency division techniques. Moreover, the magnetic field is hardly affected by the interference of surrounding metals, conductors or human bodies.
因此， 目前在短距离通信的领域中， 越来越多地应用到了磁场感应来 进行信息的传送。 在现有的磁感应通信技术中， 主要是利用一个磁场传感 器通过磁场感应来发送和接收信息， 该磁场传感器即作为磁场的发生器来
发送信息又作为磁场的感应器来接收信息。 事实上， 磁场的发生与感应是 两个不同的过程， 就磁场发生而言， 其目的是产生较大的磁场来保证发射 信号的强度， 而对于磁场感应来说， 其目的在于提高磁场感应灵敏度。 南 者目的不同， 所需釆用的技术手段必然也不相同， 而现有的磁场传感器即 作为磁场的发生器又作为磁场的感应器， 这就产生了如下的缺陷： 因为要 兼具发送与接收两种功能， 这反而导致了对两种功能的分别削弱， 使发送 与接收都难以得到最优化。 Therefore, in the field of short-range communication, magnetic field induction is increasingly applied to transmit information. In the existing magnetic induction communication technology, a magnetic field sensor is mainly used to transmit and receive information through magnetic field induction, and the magnetic field sensor is used as a generator of a magnetic field. The sending information is in turn used as a sensor for the magnetic field to receive information. In fact, the occurrence and induction of a magnetic field are two different processes. In terms of magnetic field generation, the purpose is to generate a large magnetic field to ensure the intensity of the transmitted signal. For magnetic field induction, the purpose is to improve the sensitivity of the magnetic field. . The purpose of the South is different, and the required technical means are inevitably different. The existing magnetic field sensor acts as a magnetic field generator and as a magnetic field sensor, which has the following drawbacks: Receiving two functions, which in turn leads to a separate weakening of the two functions, making it difficult to optimize both transmission and reception.
基于上述原因， 确实有必要对现有的通信用磁场传感器进行改进。 发明内容 For the above reasons, it is indeed necessary to improve the existing magnetic field sensor for communication. Summary of the invention
