Smart public toilet application scheme based on PLC data acquisition gateway

Introduction

The Jrepus smart public toilet IoT solution is based on wireless communication technologies such as 5G, 4G, and WiFi. Through Jrepus' powerful edge computing capabilities, IoT gateways, wireless data transmission/collection equipment, and smart modules, etc., are equipped with corresponding peripheral sensors, such as display Screen, camera, temperature and humidity sensor, odor detector, human body infrared sensor, one-key call for help, etc., and transmit the data collected by the sensor network to the server or cloud platform to realize the management of smart public toilets and improve the comfort of people's urban life .

The smart public toilet includes five parts: environmental monitoring and alarm and early warning, toilet position sensing, display guidance, intelligent gateway, and cloud system management platform.  

◆ Environmental monitoring and alarm and early warning: monitor the environment inside the toilet, including odor (gas), temperature and humidity, water immersion, automatic disinfection (toilet), floor flushing, etc., all of which can be automatically linked and controlled, and the user's emergency help, smoke Triggered alarm notifications, etc.;  

◆ Toilet seat sensing: detect whether the toilet seat is occupied through infrared human body sensors or smart door locks; passenger flow equipment counts the flow of people in the toilet;  

◆ Display guidance: provide toilet location guidance services, toilet seat guidance services, etc. for tourist users; including environmental information display of toilets, passenger flow conditions, and air quality conditions in toilets;

◆ Intelligent gateway: collect the data of on-site instruments and equipment, provide equipment data to the cloud and remotely control the working status of on-site equipment, and remotely upload and download PLC programs.

◆ Cloud system management platform: big data cloud service platform, equipment operation management; data summary management, storage, analysis, etc.; and provide users with login portals and third-party platform interface services.

Summary

● Compared with previous communication technologies such as 3G, the speed of 4G communication technology has been significantly improved.  

● 4G communication system has advanced technology applications, such as: OFDM multiple access method, smart antenna and space-time coding technology, wireless link enhancement technology, etc.  

● The 4G communication system adopts new modulation technologies, such as multi-carrier OFDM modulation technology and single-carrier adaptive equalization technology, to ensure spectrum utilization and extend user terminal battery life.  

● Based on the operator's network, the points are widely distributed, which saves users expensive network construction and maintenance costs, high real-time performance, and low networking costs.  

● Support all Netcom to ensure the coverage and popularization of the network, and support APN of operators to ensure the safety and reliability of data communication.
