Smart public toilet is an intelligent public health facility based on advanced technologies such as Internet technology and Internet of Things technology, which can improve the convenience, hygiene and management efficiency of public toilets.

The main features of smart public toilets are as follows:

· Intelligent: Intelligent sensors, monitoring, automatic cleaning, three-dimensional garbage sorting and other technologies are adopted to achieve automatic control and intelligent management of public toilet facilities.

· Internet: Through Internet technology, public toilet facilities can be interconnected to improve the convenience of use and management efficiency. The location and usage of nearby public toilets can be checked through the mobile App.

· Black technology: The use of advanced technology, such as Hongkou flexible LED screen, stereo broadcasting system, positioning and navigation system, facial recognition system, etc.

· Environmental protection: Equipped with efficient garbage sorting devices and waterless cleaning equipment to realize waste resource utilization and reduce pollution to the natural environment.

· Graphic and graphic: enrich the cultural connotation of public toilets, such as wall murals, billboards, garbage cans, etc., as well as information displays such as news information and public welfare publicity. This way can provide users with more abundant services, while improving the image of public toilets.

Smart public toilets are an important measure for the society to use new technologies and new thinking to improve the urban public environment, upgrading public toilets from the traditional "smelly, dirty and disorderly" to a new era of "wisdom, green and civilized".

Lidar is a sensor that measures distance through a laser beam and records the reflected light. In smart public toilets, LiDAR is usually installed at the entrance, pit area or top of the public toilet to detect the flow of people and pit status to achieve intelligent management and service.

The application of Lidar in smart public toilets is as follows:

1. Human flow monitoring: LiDAR can detect the human flow of public toilets in real time, adjust the cleaning and disinfection plan in real time according to the changes in the number of people, and maintain the quality of the public toilet environment.

2. Pit status detection: The liDAR emits a laser in the pit area to measure the size prevalent in the pit area to determine whether the toilet space in the bathroom is occupied and whether it needs to be cleaned. When the pit is occupied, the system will record and prompt in time to speed up the repair or cleaning speed and avoid wasting time because of the user.

The advantages of Lidar in smart public toilets are as follows:

1. Enhance the safety of public toilets: LiDAR can realize the monitoring and identification of the flow of people, prevent too many people from entering or entering public toilets, and avoid the abuse or illegal use of toilets.

2. Improve cleaning efficiency: Through the monitoring of the pit area, the bathroom can be cleaned in a progressive state, rather than a comprehensive cleaning every time, which can shorten the cleaning time and reduce the occurrence of errors.

3. Reduce operation and maintenance costs: Smart public toilets can be repaired when necessary by monitoring the status of use, greatly reducing maintenance costs.

The application of Lidar in smart public toilets can make the public toilet environment cleaner and sanitary, speed up cleaning, improve work efficiency, and also reduce the maintenance cost of public toilets.
