As an international metropolis, the cleanliness of Hong Kong’s urban environment is closely related to the healthy life of its residents. With the development of science and technology, intelligent equipment plays an increasingly important role in improving work efficiency and quality of life. This article will introduce a 4G smart watch designed for Hong Kong garden cleaning and sanitation workers, which integrates health monitoring functions, and combines with background servers and small programs to form a complete set of intelligent monitoring and management system.

Product overview
​
Product name: Garden cleaning smart watch
​
Main functions: health monitoring, real-time positioning, emergency help, work management
​
Target users: Hong Kong garden cleaning and sanitation workers
​
Technical features: 4G communication, GPS positioning, heart rate monitoring, blood pressure monitoring, blood oxygen monitoring, body temperature monitoring
​
Health monitoring system
​
The smartwatch is equipped with a variety of sensors that can monitor key physiological indicators such as heart rate, blood pressure, blood oxygen saturation and body temperature of sanitation workers in real time. With this data, the system can assess the health status of workers and alert users to take action in a timely manner if anomalies are detected.
​
4G communication module
​
The watch’s built-in 4G communication module ensures that even in outdoor environments without Wi-Fi coverage, workers can maintain communication with the outside world. This not only makes it easier to call for help in an emergency, but also makes the transmission of work instructions and information faster and more accurate.
​
GPS positioning function
​
With the GPS location function, the background server can track the location of each worker in real time, ensure their safety at work, and optimize work routes and scheduling.
​
Emergency help system
​
In the event of an emergency, workers can quickly send a help signal and current location information to managers through the one-click help function on the smartwatch, so that they can get help in time.
​
Background server
​
The background server is the data processing and management center of the whole system. It not only stores the health data and location information of all workers, but also has data analysis capabilities that can predict the health status of workers based on the data and prevent potential health risks.
​
Small program
​
In order to facilitate managers and workers to view information at any time, a supporting small program has been developed. Managers can view workers’ health status, work progress and location information through the applet, while workers can receive work orders, view health reports and submit work feedback through the applet.

System advantage
​
Real-time: real-time transmission and processing of data through 4G network.
​
Comprehensive: Health monitoring covers multiple key indicators to comprehensively assess the health status of workers.
​
Convenience: One-click help and information reception, simplifying the operation process.
​
Intelligence: Intelligent analysis of background servers, early warning of health risks.
​
Interactivity: The use of small programs enhances the interaction between managers and workers.

Conclusion
​
The launch of this garden cleaning smart watch not only improves the work efficiency of sanitation workers, but more importantly, ensures their health and safety. With the continuous progress of technology, more intelligent equipment will be put into the maintenance of the urban environment in the future, and contribute to the construction of a more healthy and environmentally friendly living environment.
