随着我国人口的增长，室内公共资源（如图书馆、商场、教室等）的有限性变得日益突出。因此，对于资源有限的公共场所进行实时的人数统计，有助于人们做出更加合理的资源分配，节约人们在排队和寻找空间上消耗的大量时间。针对上述需求，设计了基于ZigBee的无线室内人数统计系统。该系统采用多组红外传感器组成人数信息的感知模块，然后通过ZigBee无线组网来实时收集传感器数据，并根据这些数据分析室内人数的变化情况，从而计算得到室内实时人数。实验结果表明，该系统能够有效统计室内人数信息，并具有低成本、低功耗、实时性强等特点。

With the growth of population in China, the limitation of indoor public resources (such as libraries, shopping malls and classrooms) has become increasingly prominent. Therefore, real-time people counting in public places with limited resources is helpful to allocate resources more reasonably, and save the time for waiting in queue up and looking for space. In response to these requirements, a wireless indoor people counting system based on ZigBee technology was designed. Multigroup infrared sensors are adopted in the system to compose perception modules of people counting information, the real-time sensor data is collected by ZigBee wireless network, the change of indoor people number is analyzed based on the data, and ultimately real-time indoor people number is worked out. The experimental results show that the system with low cost and low power consumption is capable of counting indoor people statistic information in real time.
