In 2018, Shenzhen Kinghelm Electronics Co., Ltd. (www.kinghelm.net) was officially granted an invention patent by the China National Intellectual Property Administration (CNIPA) for its independently developed technology titled “An Intelligent Container Electronic Lock Based on Beidou Positioning Communication and Its Locking/Unlocking Method” (Patent No.: ZL 201510595940.4).
The patent application was filed on September 17, 2015, published on January 27, 2016, and formally authorized on January 2, 2018. The inventor is Mr. Song Shiqiang. This authorization marks a significant technological breakthrough for Kinghelm in the field of intelligent logistics security.
The Beidou-based intelligent container electronic locks developed under the Kinghelm brand include the models Kinghelm KH-201A and Kinghelm KH-201B.
Technological Innovation: Integrating the Beidou BDS System to Enhance Logistics Security and Traceability
This invention relates to an intelligent container electronic lock composed of a housing, a lock body, and a locking plate. The lock body is installed inside the housing and cooperates with the locking plate through an insertion mechanism to physically secure container doors.
The core innovation lies in the integration of Beidou Navigation Satellite System (BDS) positioning technology. The lock body incorporates a locking mechanism, a trigger switch, and devices for information transmission and real-time data processing, enabling intelligent monitoring and control.
The information processing unit functions as the “brain” of the electronic lock. It includes a dual-system BDS/GPS positioning module, a monitoring device for detecting the open/close status of container doors, a communication module responsible for data transmission, and a microprocessor for logical control. All modules are connected to the microprocessor, forming a complete intelligent monitoring system.
The microprocessor is electrically connected to the trigger switch and controls the on/off current of the trigger switch, enabling remote or authorized unlocking of the electronic lock.
The key functionality of this intelligent lock is its ability to accurately acquire real-time geographic location data while continuously monitoring container door status. These critical data are transmitted to a monitoring center via the integrated communication module, enabling full-process transparency and visualized supervision of cargo transportation.
This technical solution effectively addresses major limitations of traditional mechanical locks, such as the inability to track cargo in real time, weak security monitoring, and delayed information feedback during logistics operations.
Application Value: Advancing Digitalization and Security Management in Modern Logistics
As global trade and supply chain management become increasingly complex, higher standards are being placed on cargo security and transportation traceability. The application of this patented technology significantly enhances both management efficiency and security in container logistics.
It can be widely applied in traditional container transportation scenarios such as maritime shipping and railway logistics, reducing the risks of theft, tampering, cargo substitution, or misdelivery. In addition, it provides effective technical supervision tools for customs inspection and the transportation of high-value or hazardous goods.
By integrating China’s domestically developed Beidou BDS satellite navigation system for positioning and communication, Kinghelm’s solution also reflects a broader industry trend toward independently controllable technologies in critical logistics infrastructure. This aligns closely with national strategies for supply chain security and information system development.
Building upon the first-generation intelligent lock Kinghelm KH-201B, Kinghelm’s technical team, led by Mr. Song Shiqiang, further developed a second-generation compact BDS intelligent container lock, the Kinghelm KH-202A. This upgraded model features a smaller form factor, longer battery life, higher positioning accuracy, and compatibility with Europe’s Galileo and Russia’s GLONASS navigation systems.
