The invention discloses a remote meter-reading intelligent monitoring system based on an NB-IoT wireless communication module, thereby solving problems of disunion of current Internet-of-Things standards, high terminal cost, and insufficient access capability. The system comprises intelligent meters, acquisition devices connected to the intelligent meters in a one-to-one correspondence manner, an NB-IoT base station and a server center. According to the invention, the NB-IoT wireless communication module is used for collection of an intelligent electric meter, an intelligent water meter, an intelligent gas meter, and three-in-one integration; the NB-IoT technology has advantages of deep coverage, massive connection, ultra-low power consumption and low cost. Effects of realizing underground communication, unifying the multi-meter communication protocol, increasing the transmission rate and expanding the communication capacity can be realized. Various relay devices are cancelled by using the NB-IoT-technology-based multi-meter integrated centralized reading; underground pipe network communication is realized; the communication protocols are simplified; the operation and maintenance costs are lowered; and the mounting space is reduced. Remote-transmitting meter reading and metering data are provided for realizing the smart water service, smart gas, and smart power supply; and thus the better services are provided for smart city building.
