现有的人流量检测装置主要包括：安装在出入口内侧的内红外探测模块、安装在出入口外侧的外红外探测模块和微处理器。假如微处理器先检测到内红外探测信号，则屏蔽后检测到的外红外探测信号，并对该场所内的人数减1，假如先检测到外红外探测信号，则屏蔽后检测到的内红外探测信号，并对该场所内的人数加1，从而实现对该场所内人数的统计。
The existing human flow detection devices mainly include: the inner infrared detection module installed inside the entrance and exit, the outer infrared detection module installed outside the entrance and exit, and the microprocessor. If the microprocessor detects the inner infrared detection signal first, then the outer infrared detection signal detected after shielding is reduced by 1. If the outer infrared detection signal is detected first, the inner infrared detection signal detected after shielding is increased by 1, so as to realize the statistics of the number of people in the place.

本设计通过按S3、S4和S5功能键实现对时间的调整。
其中，S3键为小时/分钟调整选择键；S4键为加1键；S5键为减1键。
时间调整的具体实现过程如下：
S3键功能是判断是否进行时间调整。当按一次S3键后，进入小时调整。再通过按S4、S5键进行对小时的具体调整；当按二次S3键后，进入分钟调整。再通过按S4、S5键进行对分钟的具体调整，直至和当前北京时间一直为止。
然后根据按下S2功能键的情况判断是否显示时间。若是，则将当前时间数据送8155经LED显示器显示。
进行传送。其优点是传送速度快，缺点是数据有多少位，就需要多少根传输线，适合于近距离传输
