Intelligent power utilization on-line monitoring device based on NBIOT communication

Abstract

The invention relates to the technical field of power utilization monitoring, in particular to an intelligent power utilization online monitoring device based on NBIOT communication. The device comprises a communication module, a monitoring terminal and a controller; and a power grid adopts a mode of instant power generation and instant use for electric energy between a power generation side and a power utilization side, the demand of the power utilization side is met by performing power balance in real time, and in the rapid charging process of a new energy automobile, power regulation of power supply of the power generation side has hysteresis, so that the charging experience of the automobile is weakened, and the stable operation of the power grid is inconvenient. Therefore, a card holder arranged in the monitoring terminal is directly installed on the power supply line of a power utilization terminal to monitor the electrical parameters in the power utilization process of the power utilization terminal, and a converter installed in the communication module is utilized to mark the monitored electrical parameters with an identification card in a card slot and transmit the electrical parameters to the constructed NBIOT through an antenna, so that the power utilization state of a charging pile can be mastered in real time, and the use effect of the intelligent power utilization online monitoring device is improved.

Description

technical field [0001] The invention relates to the technical field of electricity consumption monitoring, in particular to an intelligent electricity consumption online monitoring device based on NBIOT communication. Background technique [0002] NBIOT (Narrow Band Internet of Things) refers to the narrowband Internet of Things, which is built on the cellular network and coexists with the existing network. It can be directly deployed on the GSM network, UMTS network or LTE network. NBIOT has stronger coverage than GPRS , its ultra-low power consumption is based on the device's own battery, with a service life of more than 10 years, and supports tens of thousands of connections in one sector. It is applied to the field of online monitoring of electric energy, which can effectively reduce the deployment cost of monitoring devices and realize Smooth upgrades.

Problems solved by technology

[0003] The power grid adopts an instant-on-use method for electric energy between the power generation side and the power consumption side, and satisfies the demand of the power consumption side through real-time power balance. However, during the fast charging process of new energy vehicles, the impact on the grid load is relatively large. Obviously, it is difficult for the power grid to provide sufficient power supply when the car is fast-charging. At the same time, after the car's fast-charging state ends, the power regulation of the power supply on the power generation side has a hysteresis, which weakens the car's charging experience and is not convenient for the smooth operation of the power grid.

[0004] In the prior art, there are also some technical solutions for online monitoring of smart electricity consumption based on NBIOT communication. For example, a Chinese patent with the application number CN201811615069.X discloses a charging pile system based on the NBIoT Internet of Things, including smart charging piles , Internet of Things connection platform, charging pile user platform and charging pile management platform; smart charging piles are used to receive charging requests from three ways: user mobile terminals, IC stored value cards or coin insertion, and provide charging services for electric vehicles; The charging pile includes the main controller, charging power supply system, card reader, coin acceptor, NBIoT wireless communication module, etc.; the Internet of Things connection platform implements real-time two-way communication through the MQTT long connection between the NBIoT wireless communication module and the main controller; charging pile users The platform is used to receive the user's charging request and send it to the main controller through the Internet of Things connection platform; the charging pile management platform is used to receive the administrator's operating parameter configuration command for the main controller, which is forwarded to the main controller by the Internet of Things connection platform device; this technical solution provides users with more convenient charging services, realizes the network management of charging piles, and increases safety and efficiency; however, this technical solution does not solve the power consumption of charging piles in the grid during use The impact problem of the charging pile makes the fast charging power of the charging pile limited by the output power of the grid, which reduces the use effect of the charging pile of the electric equipment
