Problems solved by technology

[0003] However, during long-distance driving, the state of network signal strength is constantly changing. On the one hand, due to the inherent high power consumption of mobile networks in data service mode, changes in network signal strength will affect the performance of battery-powered vehicle terminals. On the other hand, the signal change is likely to interrupt the real-time monitoring of the vehicle by the remote management personnel, causing the vehicle to be out of the monitoring for a short time, and there is a certain risk
[0004] If the network signal on the driving path can be predicted and managed to a certain extent, problems such as communication interruption can be avoided in advance. Therefore, a signal strength management system for remote control is urgently needed to monitor the network signal strength of the vehicle terminal and communication methods for monitoring and management

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a remote control signal strength management system and method. Background technique [0002] In the logistics field, in the process of cargo transportation, real-time monitoring of the status of the cargo and the driving status of the vehicle is required. The monitored data needs to be uploaded to the background server in real time through the network, so as to facilitate remote control and supervision. Mobile Internet has become the first choice for mobile access due to its characteristics of good mobile switching and low tariff. [0003] However, during long-distance driving, the state of network signal strength is constantly changing. On the one hand, due to the inherent high power consumption of mobile networks in data service mode, changes in network signal strength will affect the performance of battery-powered vehicle terminals. On the other hand, the signal...
