[0017] Beneficial effects:

[0018] 1. This indoor fire hydrant box water pressure real-time intelligent monitoring device, through the setting of insulation components, temperature controller, water pressure sensor and alarm components, allows for the setting of maximum and minimum water pressure thresholds on the water pressure controller. The water pressure sensor is used to detect the water pressure inside the fire hydrant body. When the detected water pressure exceeds the maximum threshold or falls below the minimum threshold, the water pressure controller controls the alarm light to sound an alarm to remind personnel to come and check. In winter, when the temperature is low, the water inside the fire hydrant body may freeze. At this time, the temperature controller controls the heating network to heat the water inside the fire hydrant.
