摘　　要：为实现都市公厕信息化管理,给广大市民和旅客提供公厕使用情况的信息服务,公厕蹲位显示系统采用51单片机进行数据采集并控制LED屏显示,以实现高性价比的目的。本系统用磁控开关作为信号源,通过"STC12C5A60S2单片机最小系统+08接口+LED显示屏"的精简硬件结构将蹲位使用情况信息实时、准确地显示出来。该系统现已在实际项目应用中通过测试,具有耗电量低、成本低廉、灵敏度高、美观大方等优点。此外,从更广阔的应用角度考虑,试图将该系统推广到银行营业排队人数显示、停车场剩余车位显示等公共服务领域信息可视化应用场景中去。In order to realize the information management of public toilet in city and provide the general public and tourists with the information service about using situation of public toilet, the public toilet kneeling-squatting position display system uses 51MCU to collect data and control the LED panel for the purpose of improving the ratio of performance. The system uses magnetic switches as signal sources and uses the simple hardware structure of ＂STC12C5A60S2 single chip microcomputer minimum system ＋08 port ＋ LED panel＂ to show the real-time and accurate information of using situation about public toilet. The system has been applied in practical project and past the test; it has the virtues of low power consumption, low cost, high sensitivity, beautiful and generous, etc. In addition, from the wider application point of view, this paper tried to promote the system to applications to display the num- ber queuing up in bank, and display remaining the parking number in parking, and field of other public service in information visual- ization application scenarios.
