[0002] In the field of thermal energy equipment, vacuum hot water boilers are widely used in residential heating, commercial hot water supply and other scenarios due to their stable operation and relatively low energy consumption.

[0003] However, existing vacuum hot water boiler systems suffer from insufficient intelligent control and inconvenient operation and maintenance in practical applications. Specifically, existing boiler control systems mostly use generic brands, lacking targeted design and remote monitoring and control functions. Maintenance personnel must be on-site to monitor equipment operation, resulting in low efficiency and high costs. For example, an industrial park using four traditional vacuum hot water boilers required two maintenance personnel to work in shifts 24 hours a day to monitor parameters such as boiler temperature and pressure. In case of a malfunction, there was no timely remote response. On one occasion, the failure of operators to detect abnormal boiler pressure in time led to equipment shutdown, affecting the normal production of three companies in the park and causing economic losses of approximately 80,000 yuan.
