Embodiment 1

[0035]Embodiment 1. First, the power company deploys and applies NB-loT networks in the 470MHZ frequency band, and builds three NB-loT base stations in the county-level area to form a basic NB-loT network. The cells in the county-level area randomly select multiple access points. The collector of a smart meter, the NB-loT-based power multi-service access terminal connects to the collector of the electric energy meter through the RJ485 interface, collects the status information of the electricity and the state information of the electric energy meter, and passes through the NB-loT of the electric multi-service access terminal. The loT communication module processes and transmits the data to the encryption chip for encryption, then sends the information to the NB-loT base station through the radio frequency signal, and the collected information transmits the data to the communication interface machine through the NB-loT network for data conversion, and the communication interface ...

Embodiment 2

[0036] Embodiment 2, the electric multi-service access terminal based on NB-loT is connected to the collector of the electric energy meter through the RJ485 interface, and the state information of the electric quantity and the state information of the electric energy meter are collected, and after data processing and encryption by the electric multi-service access terminal, the The information is sent to the NB-loT base station through radio frequency signals. When the communication failure of the NB-loT base station fails to receive the radio frequency information, the NB-loT communication module of the power multi-service access terminal transmits the collected service data to the SIM card. The SIM card transmits the collected data to the communication interface machine of the main station through the GPRS network, and the data processed by the communication interface machine is transmitted to the collection server through the firewall, and finally the collection server transm...

Embodiment 3

[0037] Embodiment 3, the user issues an instruction for remote device parameter configuration on the interface of the NB-loT terminal communication management system. First, the user selects the specified device, remotely configures the port parameters of the device, executes the command signal for adding device parameters, and the communication interface machine converts the command into a radio frequency signal and transmits it to the NB-loT base station, and finds the corresponding power multiple through the connection relationship of the NB-loT network. The service access terminal, when the NB-loT terminal antenna receives the command signal, transmits the command information to the NB-loT communication module, and the NB-loT communication module executes the command of the terminal communication management system, adds device parameter configuration, and The LCD display module shows that the device parameter configuration is successful.

Abstract

The invention discloses an NB-loT-based power multi-service access terminal and a management system. The terminal includes an NB-loT communication module, a power supply module, an LCD display module,an antenna, a SIM card slot, a communication interface, an encryption chip, a warning light, and a reset button. After an NB-loT terminal collects electric quantity and sensing service information ismetered, the power multi-service access terminal transmits collected information to an NB-loT base station, and the collected information is transmitted to a terminal management system of a primary station through an NB-loT network. The NB-loT-based power multi-service access terminal and the management system solve the problem that an existing wireless communication network is less in user capacity and is insufficient in covering capability and the technical problem of remote management of a terminal device, the safety of wireless communication data transmission is improved, effective monitoring and management of a terminal node are achieved, and an operation and maintenance management level is improved.

Description

technical field [0001] The present invention relates to the technical field of narrowband Internet of Things application, in particular to an NB-loT-based power multi-service access terminal and management system. Background technique [0002] With the continuous extension of the communication smart grid from the power grid side to the user side, the development of new business is deepening, and the demand for the number of terminal access of provincial companies has expanded from the original hundreds of thousands of substations to the hundreds of thousands of 10kV power distribution systems And tens of millions or even billions of user terminals, so mass terminal communication is an urgent problem to be solved in the current power communication network. At present, the terminal communication network mainly adopts optical fiber and LTE wireless technology to solve the 10kV power distribution system, but there are still a large number of service points located in indoors, ba...
