The intelligent fire hydrant launched by Weichuan Technology is a powerful fire monitoring device. The product is mainly used to monitor the water pressure of the fire hydrant, ensuring that the equipment operates well. When there is a malfunction or significant water pressure fluctuation, the supervisory unit is notified in a timely manner for fault location and equipment maintenance, greatly reducing the cost of manual inspection and achieving wide coverage monitoring, strengthening the safety guarantee of the public. Smart fire hydrants can monitor the water pressure level of the hydrant in real time, and provide alarm reminders if the water pressure deviates from the normal range. This fire hydrant monitoring system based on long-distance communication technology has the advantages of low cost, easy installation, and simple maintenance.
