I. Company Overview: Beijing Bohuaxin Zhi Technology Co., Ltd. (Bohuaxin Technology) is a high-tech enterprise specializing in the field of Condition-Based Maintenance (PHM) for critical equipment. It focuses on industrial Internet, industrial AI, condition monitoring of industrial cloud equipment, and health management. The company’s main products include wireless monitoring systems, wired monitoring systems, offline inspection systems, and more. II. Main Products: 1. Product Applications: ① Monitor the operating status of equipment, reduce the workload associated with manual inspections, and improve the efficiency of manual management ； ②Significantly reduce the occurrence of serious accidents involving mechanical equipment ； ③Report to the police promptly, take preventive measures in advance to eliminate the conditions that lead to failures, reduce unplanned downtime, and extend the operational cycle ； ④It provides a scientific basis for maintenance work, helping to avoid both excessive and insufficient testing. It also enables targeted maintenance efforts, reduces maintenance costs, and improves efficiency ； ⑤It ensures the long-term and stable operation of equipment, increases a company’s “potential” profits, and enhances its competitiveness in the market. 2. Advantages of Bohua’s products: Intelligent early warning: A unique intelligent early warning technology based on vibration acceleration, with an accuracy rate of over 95% ； Intelligent diagnosis: Industry-leading automatic diagnosis technology that enables automatic detection of imbalances, misalignments, bearing failures, fluid-related issues, and loose connections ； Data identification: Industry-leading fake information identification technology that effectively reduces the false alarm rate ； Three-in-one solution: An industry-leading comprehensive solution that offers full coverage for wired, wireless, and offline systems. 3. Product Overview of Wireless Nodes: The BH306 wireless monitoring node is a wireless temperature and vibration sensor based on the NB/CAT1 network. It offers real-time monitoring and early warning functions through an app and an online cloud IoT platform, helping manufacturing enterprises reduce losses, increase efficiency, and ensure safe operation over extended periods. Equipped with a high-capacity battery and a proprietary low-power algorithm, it is suitable for long-term monitoring of industrial equipment. No wiring is required; monitoring can begin with just one node. Through the concept of “Internet + industrial services,” it assists equipment manufacturing companies in transitioning toward service-oriented manufacturing. ①Easier to install; ready for use once powered on ； ②Fully functional, integrating collection, monitoring, alarm, and communication capabilities ； ③It has a long battery life; it can be used for two years in normal operating mode ； ④Flexible configuration; various parameters can be customized according to the actual conditions of the device ； ⑤Standard API interface for flexible integration with third-party systems, supporting both integration and being integrated. Hardware features: ① IP68 rating for water and dust resistance ； ②Built-in antenna, compact size ； ③The outer shell is made of a highly durable material, suitable for various installation scenarios ； ④The ultra-low power design ensures a battery life of 2 to 4 years ； ⑤Ultra-wide frequency response range of 0.5Hz to 15kHz ； ⑥Operating temperature range: -40°C to 85°C℃ ； ⑦Supports real-time vibration monitoring with immediate reporting when limits are exceeded (hardware version number with the last two digits being 52 or higher) ； ⑧Supports adaptive adjustment of operation mode based on the startup and shutdown status of the device (firmware version number) ； ⑨Supports configuring modifications via Bluetooth communication ； ⑩Supports custom sampling configurations and working modes. Software features: ① Supports long waveforms ； ②Remote control of sensors to modify configurations or perform OTA upgrades ； ③Supports retrieving historical data ； ④Automated resending of cached data when the network is disconnected ； ⑤Cloud-based intelligent diagnostic alerts. Hazardous area permit: Meets the requirements for Class II and Class III explosion-proof environments. 4.
