1. Background At
present, with the continuous development of smart city applications such as the Internet of Things, many places that we felt inconvenient before have been gradually solved by artificial intelligence. The "toilet revolution" was born in this wave. The most notable feature of modern smart public toilets is the intelligent guidance system. With this system, people can clearly understand the distribution of male and female toilets and the third toilet through the electronic display on the outer wall of the smart public toilet. In order to comprehensively improve the management level of public toilets, establish a long-term management mechanism to realize a modern, informatized, automated, and intelligent "smart toilet".
2. Scheme principle
Smart public toilet is the product of "toilet revolution" and smart tourism. It uses wireless communication technologies such as 3G/4G/5G and WiFi, and terminal equipment (such as: display screen, camera, gas detector, temperature and humidity detector, Light energy wireless door sensor, indicator light, human body infrared sensor, etc.) Through the third-party M2M cloud management platform through Chenmai’s operating companies, it is possible to implement unified monitoring of the operating status of smart public toilet terminals scattered in different locations, effectively reducing the operation of enterprises Maintenance costs, improve the safety, practicability and comfort of users in the toilet. Create efficient, intelligent, convenient and clean urban environmental sanitation services, and continue to maintain the level of urban environmental sanitation services and urban civilization.
The smart public toilet system is mainly composed of four parts: perception layer, transmission layer, application layer, and terminal layer.
(1) Perception layer, including data acquisition equipment, light sensitive sensors, temperature and humidity sensors, gas detectors, water volume sensors, video surveillance cameras, etc.
(2) At the transmission layer, the wireless router realizes data wireless transmission through 5G/4G/3G and other networks, and uploads various data of the front-end equipment to the central management system.
(3) The application layer is the smart public toilet management platform. It is responsible for monitoring, managing and analyzing the real-time data of the entire Internet of Things system acquired by the perception layer (such as: malodorous gas, temperature and humidity data, passenger flow statistics, toilet occupancy display, resource consumption and equipment Failure etc.)
(4) The terminal layer refers to smart phones, ipads, computers, PCs, etc., which can obtain real-time operation data and fault alarm information of the equipment in the system in time.
Three, system function
1. Platform management function
Collect the data through the gateway to the cloud platform for analysis, processing, and feedback to the public toilet display, public toilet APP or public toilet scanning applet.
2. One-key alarm function
People in the toilet, if they have physical discomfort or an accident, they can press the Chenmai passive wireless pager to send out a distress signal.
3. Flow monitoring function
The flow of people is detected by the camera and uploaded to the server, so that personnel can be reasonably allocated to clean the public toilets, reducing personnel costs; the platform will promptly inform APP users of the situation of the pit, so as to smooth the flow of people and relieve the pressure of public toilets.
4. Automatic door lock function
In each squatting room, an infrared door sensor is added, and the human body is automatically locked by infrared induction. The kinetic energy generation technology of Chenmai Technology is used to send a wireless signal to the master when opening and closing the toilet door.
5. Environmental monitoring function
The environmental collection system collects the temperature, humidity, NH3, H2S and other irritating gases in the entire toilet in real time, uploads it to the server, and then dispatches tasks to maintenance personnel.
6. Multi-network intelligent switching backup function
If the network is abnormal or disconnected, the entire wireless network will automatically switch to the backup network WIFI or 4G to ensure the normal and effective operation of the overall network data.
7. Energy saving system
Smart water and electricity meters can collect the electricity and water consumption of the entire toilet and send the data back to the server to monitor whether the toilet water or electricity consumption is too large.
Fourth, the core product of
the system The core equipment of the system is the CM520-8 3G/4G wireless router to establish a link transmission channel for smart public toilets and enterprise business platforms. This product is an industrial-grade product based on 5G/4G/3G wireless network communication , Using 32-bit high-performance industrial-grade MIPS communication processor, embedded real-time operating system RTOS as the software support platform, the system integrates a full range of communication protocols from the logical link layer to the application layer, supports static and dynamic routing, PPP server and PPP client, DHCP server and DHCP client, DDNS, firewall, NAT, DMZ host and other functions. The device can provide users with a safe, high-speed, stable, and reliable wireless routing network for routing and forwarding various protocols, and help smart public toilet terminals realize 5G/4G wireless network access networking and remote management services.

V. Summary
The solution of smart public toilets is the key to the toilet revolution. It is necessary to conduct on-site surveys of the target toilets, carefully analyze them, and formulate detailed tailor-made design plans. Responding to the call to comprehensively build a modern new city and create a "smart city" intelligent public toilets are currently urgent problems to be solved.
