智慧停车都在跟进的NB-IoT，到底是个什么技术
随着停车难现象的日益严重，智慧停车行业异军突起，进入发展快车道。不知道大家有没有发现，许多智慧停车企业在宣传的时候都用到了NB-IoT技术这个词汇。
既然这么受欢迎，这个NB-IoT技术到底是个什么东东？其实NB-IoT是Narrow
Band Internet of
Things的缩写，即窄带物联网，NB-IoT构建于蜂窝网络，只消耗大约180KHz的带宽，可直接部署于GSM网络、UMTS网络或LTE网络，以降低部署成本、实现平滑升级。因为它耗能少，传输快，可以达到的效果也很好，我们目前看到的物联网技术应用，基本上都是窄带物联网。
当然研究技术细节不是本文的目的，我们只需知道NB-IoT叫做窄带互联网，是物体与物体之间的信息交互的一种方式，是基于互联网技术实现的。
和传统的互联网相比，物联网有其鲜明的特征。
首先，它是各种感知技术的广泛应用。物联网上部署了海量的多种类型传感器，每个传感器都是一个信息源，不同类别的传感器所捕获的信息内容和信息格式不同。传感器获得的数据具有实时性，按一定的频率周期性的采集环境信息，不断更新数据。
其次，它是一种建立在互联网上的泛在网络。物联网技术的重要基础和核心仍旧是互联网，通过各种有线和无线网络与互联网融合，将物体的信息实时准确地传递出去。在物联网上的传感器定时采集的信息需要通过网络传输，由于其数量极其庞大，形成了海量信息，在传输过程中，为了保障数据的正确性和及时性，必须适应各种异构网络和协议。
还有，物联网不仅仅提供了传感器的连接，其本身也具有智能处理的能力，能够对物体实施智能控制。物联网将传感器和智能处理相结合，利用云计算、模式识别等各种智能技术，扩充其应用领域。从传感器获得的海量信息中分析、加工和处理出有意义的数据，以适应不同用户的不同需求，发现新的应用领域和应用模式。
窄带物联网的应用模式和物联网是一样的，简单的说，窄带物联网是物联网的一个分支技术，窄带物联网特点是传输速度快，耗能少，可以提高电池寿命。
正是因为窄带物联网有了这么多优点，在势头正盛的智慧停车领域得到了广泛应用，停车场的车位信息实时获取、停车场流量的监控、空闲车位导航、反向寻车的实现等便捷功能都能依靠窄带物联网技术变得更简单。
车停停车深入的研究、结合窄带物联网技术，配合大数据、云计算技术，为停车场提供智慧停车解决方案，帮助停车场用最低的成本，实现停车场智慧化升级改造。
