Problems solved by technology

[0005] The disadvantage of the existing technology is: after the centralized controller is powered on, all street light terminals are powered on at the same time, and a large number of terminals are connected to the network at the same time
At this time, the number of access terminals in the local area is too large, and the capacity of the PRACH channel of the base station is insufficient, resulting in failure to access the network
At the same time, a large number of terminals access the network at the same time, and failed terminals repeatedly access the network, resulting in a significant increase in network uplink interference, causing a large number of terminals to fall into a vicious cycle of access failure, uplink transmission power increase, and uplink interference increase
As a result, a large number of terminals fail to access the network, or fail to report data, and the overall network performance deteriorates

Abstract

The invention discloses a discrete access method and structure of an NB-IoT intelligent street lamp terminal, and the structure is connected with a RESET interface of an NB-IoT communication module through a control line, and achieves the delayed power-on function of the NB-IoT communication module through program control. Or a direct-current power supply distributor is connected in series between a power supply circuit and the NB-IoT communication module, and then a microcontroller controls the direct-current power supply distributor to supply power to the NB-IoT communication chip without a RESET pin in a random delay manner, so that the power-on time of each street lamp terminal is staggered to realize discrete network access. According to the invention, the problems of insufficient instant network resources and greatly improved uplink interference level caused by simultaneous network access of a large number of terminals when the NB-IoT intelligent street lamp is powered on can be solved, and the NB-IoT network communication success rate and the terminal data reporting success rate are improved.

Description

technical field [0001] The present invention relates to the technical field of NB-IoT intelligent street lamps, in particular to a discrete access method and structure of NB-IoT intelligent street lamp terminals. Background technique [0002] Such as figure 1 As shown, the existing NB-IOT smart street light system uses a control center, a centralized controller, and street light terminals to form a system. The street light terminals use NB-IOT communication modules to connect to the network and return data. [0003] The existing system uses NB-IoT (Narrow Band Internet of Things, Narrow Band Internet of Things) street light terminals to directly connect to the power module through the mains, and the power module supplies power to the lighting circuit module, MCU (micro control unit), and NB-IOT communication module respectively. [0004] Such as figure 2 As shown, after the mains is powered on, the MCU and NB-IoT communication module are powered on at the same time and st...
