Company Introduction

Founded in 2007, Zhejiang Xinzailing Technology Co., Ltd. is a comprehensive IoT technology and operations service provider. The company is dedicated to providing IoT solutions and operating platform services, with the aim of building the biggest smart elevator management and service platform in China. Xinzailing also monitors environments and offers smart home solutions.
The company has grown quickly— it currently has over 500 employees and many wholly-owned subsidiaries, such as Hangzhou Zailing Electronic Technology Co., Ltd., Hangzhou Zailing Yunti Information Technology Co., Ltd., Shanghai Zailing Information Technology Co., Ltd., Hangzhou Zailing E-Commerce Co., Ltd., and Zhejiang Pengyan Technology Co., Ltd.


Elevators are an important transportation tool used in people's daily life. As the number of elevators increases rapidly, safety incidents, such as people becoming trapped or injured in elevators are occurring more frequently and are often reported on by the media. These types of incidents are usually caused by older elevators that are near the end of their life cycles and have not been properly maintained. These safety issues have caused a public outcry, leading people to demand safer elevators. General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (AQSIQ) has issued multiple reports with the goal of improving elevator safety.

Currently, Hangzhou has nearly 110,000 elevators, with 10,000 new elevators being added every year. With such a large number of elevators, new challenges continue to emerge in elevator safety management and that must be effectively resolved. Challenges include:

Large quantities of elevators are aging.

Elevators are not being properly maintained due to insufficient maintenance expenditure or manpower.

Passengers may behave inappropriately, such as hitting or blocking the door, forcing the door open, and smoking in the elevator. These types of behaviors are responsible for 60% of all elevator incidents.


Xinzailing has worked with Huawei to build an elevator safety management system known as Yunti to ensure the safety of elevators.

Yunti is an integrated service platform that incorporates IoT and Big Data technologies to monitor and manage elevator statuses, supervise passengers, detect and handle faults, and respond to emergencies. Yunti collects dynamic elevator data in a timely manner to identify risks, serving as a preventive measure against incidents and helping to resolve incidents efficiently. With Yunti, the elevator incidents can be prevented by dealing with the root causes of the incidents, enabling responsible government bureau to effectively safeguard public safety.

• Unique AI-based management:
The Yunti AI system automatically monitors, manages, and handles elevator operations with minor human assistance to improve efficiency. The system also supports self-evolution and self-upgrading.

• Video-based behavior analysis
Yunti can analyze videos to identify inappropriate behaviors in elevators, and quickly issue warnings to passengers. This prevents safety incidents caused by human-inflicted damage to elevators.

• Targeted maintenance and preventive warning:
Yunti uses preventive warnings to enhance elevator security. Data recorded by maintenance personnel is uploaded to Yunti to be analyzed along with data obtained through real-time monitoring in order to identify potential risks. This shift from traditional periodical maintenance to more effective targeted maintenance greatly improves elevator safety.

As illustrated in the figure, Yunti collects massive quantities of data and uses various methods to transmit the data to the background. The system background then processes the data in real time and reports information to relevant parties, such as maintenance personnel, property management personnel, or quality supervision departments. During this process, large quantities of data arrive at the system background from networks around China. For example, in Hangzhou's Yuhang District alone, there are over 100,000 connected elevators concurrently accessing the system. If all of the elevators in Hangzhou are connected to the system, the background must meet all of the following requirements in order to work smoothly:

Efficiently process a large number of concurrent access requests
If elevators in all of Hangzhou's 10 districts are connected to the system, over a million elevators will access the background concurrently.

Provide high-performance data processing
The background must use Big Data technology to process large amounts of collected video, physical, and environmental data in real time, and sends information to related parties.

Provide reliable maintenance services
Elevators operate non-stop, 365 days a year. If an elevator if out of service, it can greatly inconvenience the public. Therefore, the background must be highly reliable and able to tolerate faults.

Allow for the access of elevators nationwide
In addition to the elevators located in Hangzhou, the system must also be able to connect to elevators all across the nation.

Ensure data security
The data collected by the system is important and must be protected from security threats.

Support AI
Yunti uses AI video identification technology, and must support the deep learning algorithms in order to process large quantities of video data samples.

Throughout the entire Yunti system, Xinzailing uses the following Huawei cloud service resources to provide services for customers:

Cloud computing resources such as ECS server, Docker container, GPU-accelerated cloud containers, and bear metal server

Storage resources such as CDN and Object Storage Service

Network resources such as Virtual Private Network (VPN)

Big Data basic services such as Data Ingestion Service (DIS), Data Warehouse Service (DWS), MapReduce service, data mining service, and third-party AI service

Customer Benefits

• For the public
Properly maintained elevators ensure the convenience and safety of passengers.

• For the government
The government can improve public safety efforts to ensure the well-being of its citizens. Furthermore, Yunti is an important component of smart city development.

• For Xinzailing
Huawei and Xinzailing's collaborative efforts in deploying Yunti enable Xinzailing to improve the management of tens of thousands of elevators. Elevator statuses can be viewed in a centralized manner, eliminating the need for O&M personnel to collect data onsite. The elevator status data can be obtained quickly and continuously, detecting problems immediately after or even before they occur. Personnel can use this data to schedule resources more appropriately and implement preventive maintenance, thereby minimizing safety risks.

Huawei cloud services provide Xinzailing with a highly-reliable system that can handle large numbers of concurrent access requests with high-performance data processing. Elevators nationwide can be connected to a stable network anytime anywhere to transmit real-time status data to the cloud without any loss. Additionally, scalable resources make quick service rollout and expansion possible, significantly reducing operating expenses for Xinzailing.
