本发明涉及通信技术领域，特别是涉及一种物联网数据采集端及其通信方法和系统。The invention relates to the field of communication technology, in particular to an Internet of Things data acquisition terminal and a communication method and system thereof.
【背景技术】【Background technique】
在物联网技术领域，传感器依托网络和通信技术实现感知信息的传递和协同。传感器的网络技术分为两类：近距离通信以及光与网络通信技术等。在近距离通信方面，目前应用较多的为免许可证的2.4GHz ISM频段的相关传感节点设备，如Wi-Fi、蓝牙、Zigbee(IEEE 802.15.4协议的代名词)和SubGhz等。In the field of Internet of Things technology, sensors rely on network and communication technologies to realize the transmission and collaboration of perceived information. Sensor network technology is divided into two categories: short-distance communication and optical and network communication technology. In terms of short-distance communication, the relevant sensor node devices in the license-free 2.4GHz ISM band are widely used at present, such as Wi-Fi, Bluetooth, Zigbee (synonymous with IEEE 802.15.4 protocol) and SubGhz.
虽然上述相关传感节点设备都是低功耗设备，但是对于目前容量与体积都受到一定限制电池应用来说，此类设备的功耗还是相对过大，续航时间还不够长。而传统RFID读卡器以及CPU待机应用的电流一般为80mA/5V，其电源转换会带来功率损耗，实际消耗功率达500mW。同时，三种技术都是基于2.4g频段展开的，在自由空间传播的损耗较大，在同样的发射功率(10mw)情况下，难以做到有效传输距离超过100m以上。Although the above-mentioned sensor node devices are all low-power devices, the power consumption of such devices is still relatively high and the battery life is not long enough for current battery applications with limited capacity and volume. However, the current of traditional RFID card readers and CPU standby applications is generally 80mA/5V, and its power conversion will cause power loss, and the actual power consumption is up to 500mW. At the same time, the three technologies are all based on the 2.4g frequency band, and the loss of propagation in free space is relatively large. Under the same transmission power (10mw), it is difficult to achieve an effective transmission distance of more than 100m.
因此，上述相关传感节点设备应用于物联网数据采集设备端，会耗费较高的功耗，会增加物联网数据采集设备端的充电频率和电池更换频率。Therefore, the application of the above-mentioned related sensor node devices to the IoT data collection device will consume relatively high power consumption, and will increase the charging frequency and battery replacement frequency of the IoT data collection device.
