Yunnan South Asia Elevator Co., Ltd.'s Elevator IoT Technology: Yunnan's Smart Elevator Solutions

　　Driven by the dual forces of the Belt and Road Initiative and Yunnan's strategic focus on "strongly developing industries and prioritizing manufacturing," Yunnan South Asia Elevator Co., Ltd. has emerged as a leading enterprise in Yunnan Province's specialized equipment manufacturing sector. Leveraging its state-of-the-art 42,000-square-meter factory located in the Yanglin Economic and Technological Development Zone, the company has seamlessly integrated elevator IoT technology into every stage of its operations—research & development, production, and service—creating a smart management system that spans the entire lifecycle of elevators. This innovative approach not only elevates Yunnan’s capabilities in elevator manufacturing but also positions the province’s “Made in Yunnan” intelligent solutions as a key player in penetrating markets across South Asia and Southeast Asia.

　　 I. Technical Architecture: The Intelligent Hub for Cloud-Based Collaboration

　　South Asia Elevators' IoT system is built around a core three-tier "cloud-pipe-device" architecture. By deploying IoT monitoring terminals on top of elevator cabs, the system continuously collects real-time data on elevator operation parameters, safety status, and environmental conditions. These terminals integrate network routing and sensor connectivity features, enabling direct data links with production equipment such as laser cutters and CNC bending machines—creating a closed-loop monitoring system that spans from the manufacturing stage all the way to end-user operations. For instance, in an 85-meter-high elevator test tower where seven hoistways simultaneously operate different elevator models, the IoT system can instantly compare test data, helping to refine product designs for optimal performance.

　　The system employs a cellular networking model, where a single data node is sufficient to cover all elevators within one cell. Combined with cloud-based server architecture, this approach reduces the per-elevator traffic cost to 30% of the industry average. Additionally, the company’s 1,500-unit-per-year elevator production line—currently undergoing commissioning in 2025—has already achieved end-to-end digital control, spanning everything from steel plate cutting to finished product shipment. Moreover, the IoT platform enables full traceability, allowing users to track installation data for every single screw throughout the entire manufacturing process.

　　 II. Core Function: From Passive Maintenance to Proactive Prevention

　　1. Intelligent Early Warning and Self-Diagnosis of Faults

　　The system comes equipped with a library of over 2,000 fault models, leveraging machine learning algorithms to analyze historical data and predict potential risks—such as traction machine bearing wear or wire rope strand breakage—up to 72 hours in advance. In 2024, this technology successfully alerted authorities to the risk of fatigue-induced wire rope failure in an elevator at an office building in Kunming, preventing a major safety incident.

　　2. The "Golden 4 Minutes" for Emergency Rescue

　　When an elevator entrapment incident occurs, the system automatically activates a three-level response mechanism:

　　Within 10 seconds: Identify the number and location of trapped individuals using intelligent video equipment inside the elevator car.

　　Within 30 seconds: Simultaneously push precise location information to property management, maintenance providers, and the 96333 emergency platform.

　　Within 4 minutes: Initiate video-based voice reassurance, guiding the trapped individual to assume a safe posture.

　　In the first half of 2025, the system reduced the average rescue time by 62% compared to traditional methods across 127 elevator entrapment incidents handled in Kunming City.

　　3. Energy Efficiency Management and Carbon Footprint Tracking

　　Based on the unique climatic characteristics of the Yunnan Plateau, an adaptive energy-saving mode has been systematically developed:

　　Dynamically adjust lighting brightness based on elevator usage frequency.

　　Automatically switches to standby mode during idle periods.

　　Utilizing an energy feedback device to return braking energy back to the power grid.

　　In a pilot project at a residential community in Kunming, the annual electricity consumption of a single elevator dropped by 18%, equivalent to reducing carbon dioxide emissions by 1.2 tons.

　　 III. Application Scenarios: A Smart Ecosystem with Comprehensive Coverage

　　1. Old Building Renovation "Revitalization Program"

　　Addressing the elevator upgrade needs in older residential communities in Yunnan, Nanya Elevator has introduced an IoT-powered retrofit solution for adding elevators. At the Expo Shou'an project on Longqing Road in Qingyun Subdistrict, Panlong District, Kunming, the company has integrated lightweight IoT modules into the existing building structure, enabling:

　　Real-time monitoring of wall stress changes during construction

　　Runtime Automatic Load Distribution Balancing

　　Predicting steel structure fatigue life during the maintenance period

　　This project has reduced the construction period for elevator installations by 40% and lowered maintenance costs by 35%.

　　2. Cross-border Elevator Regulatory Platform

　　Leveraging the locational advantages brought about by the opening of the China-Laos Railway, Nanya Elevator has built a cross-border elevator supervision platform for the Mohan Port. This platform:

　　Synchronizing and aligning special equipment inspection standards between China and Laos

　　Achieve cross-border mutual recognition of elevator maintenance and inspection records

　　Supports multilingual emergency call services

　　In the first half of 2025, the platform has already supervised 287 elevators along the China-Laos Railway route, with the failure rate dropping by 51% compared to the same period last year.

　　3. Precise Targeting of Elevator Advertising

　　Through the intelligent display device inside the cabin, the system can:

　　Identify passenger characteristics such as age and gender

　　Dynamically adjust ad content based on time periods

　　Real-time monitoring of ad performance

　　In the T2 Terminal elevator project at Kunming Changshui International Airport, this technology boosted ad conversion rates by 27%, marking Yunnan's first successful commercial implementation of "elevator media + IoT."

　　 IV. Technical Standards: Yunnan’s Industry-Leading Approach

　　South Asia Elevator has spearheaded the development of the local standard, "Yunnan Province Elevator IoT Construction Specifications," which clearly mandates:

　　Newly installed elevators must be equipped with a dual-mode communication module (4G + LoRa).

　　The maintenance unit must respond to IoT alerts within 30 minutes.

　　Elevator operation data must be stored for at least 5 years.

　　As of July 2025, the company has secured 5 patents related to elevator IoT technologies, including the "Blockchain-Based Elevator Maintenance and Service Record Evidence System," which earned a third-place award for Scientific and Technological Progress in Yunnan Province.

　　 V. Future Outlook: Building the Elevator Industry Internet

　　South Asia Elevators is advancing the "Three Ones" initiative:

　　Unified Management System: By 2026, complete IoT integration for 100,000 operational elevators in Yunnan Province.

　　One-code traceability: Assigning a unique digital ID to each elevator, enabling full-process tracking from manufacturing to decommissioning.

　　Smart One-Screen Control: Developing an "Elevator Industry Brain" that integrates over 20 business systems spanning design, production, services, and regulatory oversight.

　　Under the leadership of the "A Life Called Yunnan" brand, Nanya Elevators is leveraging IoT technology to seamlessly integrate Yunnan’s breathtaking blue skies, fluffy white clouds, and vibrant ethnic cultures into elevator spaces—transforming every ascent and descent into a meaningful dialogue between innovation and culture. As company Chairman Zhu Jinshui puts it: "We don’t just build elevators—we’re creating a forward-thinking vertical transportation ecosystem that connects us to the future."
