The invention provides a remote meter reading method and system based on an eLTE-IoT technology. The method comprises the steps of setting an eLTE base station and registering a smart electric meter to the eLTE base station; sending a login frame of the registered smart electric meter to an IoT network; forwarding the login frame received by the IoT network to a master station, and establishing communication between the smart electric meter and the master station, thereby realizing meter reading; and instantly processing request data after the smart electric meter receives the request data ofthe master station, sending a replied data frame to the IoT network, and forwarding the replied data frame to the master station. The problem that mobile devices of common users cannot be registered with the network due to the fact that a current mainstream remote meter reading method based on a GPRS, 3G or 4G network is expensive in network communication cost and excessive in occupied bandwidth resources is solved. According to the method, an eLTE module in the smart electric meter is automatically controlled to be registered with the network, the docking with the IoT network is realized, andthe great convenience for field installation and maintenance is provided.
Description
technical field [0001] The present invention relates to the technical field of Internet of Things, and more specifically, to a remote meter reading method and system based on eLTE-IoT technology. Background technique [0002] Smart meters are used more and more widely around the world. The current communication scheme for remote meter reading between the master station and smart meters is still the mainstream of the mobile public network GPRS, 3G or 4G communication network, which is mainly divided into two types of communication: Method: The master station acts as a TCP server, and the smart meter acts as a TCP client; and the master station acts as a TCP client, and the smart meter acts as a TCP server. [0003] When the smart meter acts as a TCP client, it actively initiates a request to establish a TCP link to the master station as a TCP server. After the link is successfully established, the master station can realize remote meter reading and control the smart meter. W...
