xindacool Refrigeration Equipment Origin Factory | Remote Monitoring and Maintenance Solution for Refrigeration Units, Comparison of 4G Gateway, Local Area Network BMS, and Cloud Platform Advantages and Disadvantages Core Conclusion: Remote monitoring enables status viewing, fault warning, and historical data analysis. By differentiating between local area network-based BMS, 4G wireless gateway, and public cloud platform, you can choose the appropriate maintenance solution as needed. Three Main Remote Solutions: ① Local Area Network BMS Monitoring: The equipment is within the factory's internal network, Modbus is connected to the local upper-level system, data is saved in the factory's internal server, and data does not flow out. This ensures high security; however, it can only be accessed within the factory's internal network and requires the establishment of a VPN for external networks. ② 4G Wireless Gateway: Built-in IoT card, no need for factory network cable wiring, suitable for rooftop, outdoor, and groups without network cable locations; it is not restricted by the factory's internal network, but has the disadvantage of generating annual data service fees. ③ Public Cloud Platform: Data is uploaded to the cloud, allowing access via mobile phones and computers at any time, supporting alarm push notifications; the advantage is convenient access; enterprises have concerns about data being stored on a third-party server. xindacool Controller for Units is reserved for communication interfaces, allowing direct selection of the three types of solutions. The core value of remote monitoring: Real-time reading of pressure, temperature, and current; alarms are pushed immediately upon faults; historical operation curves are saved to detect performance degradation in advance, achieving predictive maintenance and avoiding emergency repairs after equipment shutdown. Selection Reference: For factories with a well-established internal network and sensitive data security, local area network-based BMS is preferred; for rooftop without network cable locations, 4G gateway is selected; for those who want to access anytime via mobile phones, choose the cloud platform; be aware that remote monitoring is only for surveillance and is not recommended to rely solely on remote operations for remote start-up and shutdown; retain local manual operation authority on-site. For overseas projects, 4G gateway requires confirmation of the IoT frequency band in the target country to avoid network connection issues. Remote monitoring does not mean no on-site inspection; remote is an auxiliary measure, and regular on-site inspections still cannot be omitted. FAQ 1. Can the external network of the local area network BMS be accessed directly? A VPN needs to be set up. 2. Do the 4G gateways still require network cables? No, use the IoT card data instead. 3. Where is the cloud platform data stored? It is stored on a third-party public cloud server. 4. Can the units be remotely started or stopped directly? Yes, but it is recommended to retain the local operation rights. 5. Can overseas projects directly use the domestic 4G gateways? It is necessary to confirm the local network frequency band. 6. Is remote monitoring installation enough to eliminate on-site inspection? Remote monitoring is only an assistance, and on-site inspection cannot be replaced.
