1、 1 摘摘 要要 目前绝大数商场都采用传统的进出口系统或者根本没有，并且关于顾客在某个季节对 某些商品的喜好与需求没有一个科学合理的统计调查， 造成一些商品销售库存、 另一些商品 销售短缺的尴尬局面。商场客源减少却没有及时了解，不利于商场的最佳运营。但如果专门 安排人员去调研这方面，不仅浪费资源、影响耽误顾客购物，而且得出的结果不一定准确。 鉴于此，我们设计一个自动检测商场进入顾客的总人数，现在还有多少人在商场内，对顾客 进入商场购物表示欢迎的科学系统是很有利用价值的， 其中检测可以采用激光传感器。 我们 用于此处的传感器属于第类激光，是无公害激光。因采用能量不高的激光，对人的身体不 会造成伤
2、害，所以可以放心的使用在商场进出口处作检测用。本系统还有不少缺点，例如： 当大人抱着小孩就无法正确检测进、出多少人了。虽然此系统有不足之处，但还是适合现在 商场统计人数的。 关键词：STC89C52 单片机；LCD1602 显示模块；AMS1117 稳压模块；激光传器；语音模 块 WT588D16。 2 Market Passenger Count Promotions Specialist Abstract At present, several stores all the traditional import and export system or no, and about the
3、customer in a season for some goods be fond of and demand without a scientific and reasonable statistical investigation, causing some merchandise sales inventory, some other merchandise sales the shortage of embarrassing situation. Market customers reduce but no prompt understanding, go against the
4、best market operation. But if specialized arrangements for the personnel to research this aspect, not only waste resources, influence delay customer shopping, and the results of not necessarily accurate. In view of this, we design an automatic detection market into the total number of customers, and
5、 now there are many people in a department store, shopping for customers into stores welcome scientific system is very useful, including detection can use laser sensor. We used for this sensor belong to the first kind of laser, laser is pollution-free. Because of the high energy laser, to the person
6、s body will not cause damage, so can be at ease use in the market place for inspection of import and export. This system has many disadvantages, such as: when adults hold children cannot correct detection into or out of the how much person. Although the system has shortcomings, but for now store the number of statistics.
