5) wireless transmission: by the aid of a wireless narrowband ad hoc network algorithm of the wireless ad hoc network communication module, power consumption of a communication system can be reduced to the greatest extent under the condition of guaranteeing time delay, the communication system can be opened at any time, and high power consumption of the system caused by long-time occupation of narrowband transmission data is effectively saved;
6) a power supply unit: two power supply modes are adopted, one is a special material battery which can supply power for more than several years, the other is a 18650 military standard low-temperature lithium ion battery which is reasonably configured according to the specific condition of front-end equipment deployment, and an electronic sentinel can be ensured to be on duty for more than one month.
