Yuzan Tech’s Bluetooth smart locks, leveraging the core advantages of “no external power supply required, Bluetooth wireless communication, and cloud-based intelligent management and control”, perfectly address the pain points in State Grid and operator scenarios, such as scattered equipment, complex environments, high management difficulty, and strict safety requirements. Through technical features including reverse power supply via electronic keys, dynamic encryption authorization, and full traceability of operations, they have achieved large-scale implementation in scenarios like power facility operation and maintenance, and communication base station management, significantly enhancing asset safety protection capabilities and operation and maintenance management efficiency. The following are typical application cases in these two fields.
Application Cases in the Operator Field
China’s three major operators and China Tower own millions of facilities such as communication base stations, optical distribution boxes, and data computer rooms, most of which are located in remote outdoor areas. They face challenges including difficult power supply, high lock maintenance costs, complex cross-regional management, and significant asset anti-theft pressure. Yuzan Tech’s Bluetooth smart locks have become the core solution for operators’ asset intelligent management due to their maintenance-free, strong protection, and easy integration characteristics.
Large-Scale Application Project of Passive Lock Control for China Tower Base Stations
(1) Project Background and Pain Points
As a provider of operator infrastructure, China Tower manages over one million base stations. The locks for base station equipment boxes, tower inspection ports, etc., have three major pain points: first, outdoor base stations lack stable power supply, leading to frequent failures of traditional electric locks due to battery exhaustion; second, maintenance personnel operate across regions, requiring them to carry a large number of keys, resulting in low deployment efficiency; third, base station theft incidents occur frequently, with 65% implemented through key duplication, causing annual losses exceeding ten million yuan.
(2) Solution
1.Adaptation to extreme environments: Yuzan Tech’s locks feature an IP67 dustproof and waterproof design, supporting a wide temperature range of -20℃~65℃ and being undamaged after 2-meter 6-directional drop tests. They are suitable for complex outdoor scenarios such as heavy rain, high temperatures, and extreme cold. The passive design enables maintenance-free unlocking for more than 100,000 times, meeting the outdoor operation and maintenance needs of base stations.
2.Integration of multiple communication modes: Supporting dual modes of Bluetooth local unlocking and NB-IoT/4G remote authorization unlocking. In remote areas without public network signals, emergency unlocking can be performed via Bluetooth; in areas covered by public networks, unlocking records are uploaded in real-time and abnormal alarms are pushed, adapting to communication needs in different scenarios.
3.Group-level hierarchical management: Relying on Yuzan Tech’s cloud-based centralized management platform, management permissions are assigned by province, region, and base station levels. It supports group management of locks, second-level issuance and revocation of permissions, allowing administrators to real-time monitor the status of locks in base stations nationwide and achieve group-level overall management and control.
(3) Implementation Effects
The project has achieved a comprehensive upgrade in base station lock control management: the annual maintenance cost per lock has decreased from 800 yuan to 240 yuan, and maintenance efficiency has increased by 70%; through Yuzan Tech’s national secret SM4 algorithm encryption and abnormal vibration alarm function, the incidence of base station theft has dropped to zero; the remote authorization function reduces on-site trips for personnel, shortening emergency maintenance response time by 50%, providing core support for China Tower’s “shared and intelligent” operation.

Passive Bluetooth Lock Transformation Project for China Mobile’s Outdoor Optical Distribution Boxes
(1) Project Background and Pain Points
China Mobile owns a large number of outdoor optical distribution boxes, distributed in urban street corners, remote villages, and other areas. Traditional mechanical locks have problems such as easy key loss, no unlocking records, and fiber optic interruptions caused by illegal prying. Moreover, the scattered distribution of optical distribution boxes leads to high manual inspection costs and difficult fault tracing. Annual losses due to communication interruptions caused by lock issues exceed one million yuan.
(2) Solution
The project introduces Yuzan Tech’s passive intelligent lock control system, customized and transformed for optical distribution box scenarios:
1.Keyless anti-prying design: Eliminating traditional keyholes, adopting Yuzan Tech’s Bluetooth induction unlocking technology to physically prevent technical unlocking and prying behavior. The lock body is made of 304 stainless steel, featuring strong corrosion resistance and damage resistance, adapting to the outdoor protection needs of optical distribution boxes.
2.Integrated mobile APP management: Operation and maintenance personnel connect to Yuzan Tech’s locks via mobile phone Bluetooth without carrying additional equipment. Unlocking records are automatically synchronized to China Mobile’s operation and maintenance management platform, linking with inspection work orders to ensure a closed-loop inspection process and improve operation and maintenance convenience.
3.Flexible permission control: Supporting temporary authorization function, issuing time-limited unlocking permissions to construction units and emergency repair personnel. Permissions automatically become invalid after the completion of operations, avoiding permission abuse and balancing construction needs with asset safety.
(3) Implementation Effects
After pilot promotion in multiple provinces nationwide, illegal prying incidents of optical distribution boxes have decreased by 95%, and communication interruption time has been shortened by 60%; operation and maintenance personnel no longer need to carry a large number of keys, increasing single-person inspection efficiency by 40% and reducing inspection costs by 30%; unlocking data is fully traceable, realizing the transformation of optical distribution box assets from “passive protection” to “active control”, and building a solid safety barrier for the stable operation of communication networks.
