　　Along with the constant acceleration of urbanization construction in our country, the intelligent construction of city public facilities is already the important symbol of smart city construction. As a modern urban public place, public toilets, clean surrounding environment and fresh air inside the toilets, have become an important symbol of civilization in modern urban construction。

　　There are many problems in the management of urban public toilets：

　　The basic data management of public toilets is heavy and inefficient；

　　Public toilets are "dirty and bad", which affects the use of residents；

　　The number, specifications and facilities of public toilets are outdated and backward；

　　Problem response speed lags；

　　Public participation in supervision is insufficient。

　　Therefore, in order to comprehensively improve the management level of public toilets, establish a long-term management mechanism, comprehensively build a modern new city and create intelligent public toilets in a "smart city"; The realization of public toilet flow monitoring, odor detection, toilet flow detection, squat detection, automatic deodorization and other intelligent remote management; New Internet of Things, cloud computing and other technologies have been adopted to realize the integration of sanitation toilet management and intelligent technology. The "smart public toilet" can not only eliminate the unpleasant smell, but also provide scientific and reasonable management means for the sanitation of public toilets, so that the management business of urban sanitation public toilets is more intelligent and orderly。
