Low-power-consumption intelligent fire hydrant system, control method and control system

According to the low-power-consumption intelligent fire hydrant system, the control method and the control system, on the basis of the implementation scheme of the low-power-consumption intelligent fire hydrant system, the normal-state average operation power consumption is comprehensively considered from four aspects of hardware design, software design, communication algorithm design and device type selection, the current is smaller than 30 uA, and the quiescent current is smaller than 10 uA and is far lower than the power consumption of Internet of Things equipment on the market. In the aspect of hardware, a water drainage detection circuit of the intelligent fire hydrant and an on-off control circuit of an external sensor are mainly redesigned, and in the aspect of software, logic control over system operation is mainly programmed, so that the working state of a hardware layer works according to a process control result. And after the data is successfully sent, a retransmission back-off mechanism is adopte
