Problems solved by technology

And these areas cannot use traditional RTU (remote terminal control system) for online monitoring because there is no mobile network signal
At the same time, the traditional RTU (remote terminal control system) only has a single data transmission method. When the signal of this data transmission method is not good, data upload cannot be realized.

Abstract

The invention discloses a remote terminal control system capable of intelligently switching data transmission modes and a storage medium. The system can execute the following methods: judging whethera signal meets a transmission requirement or not through an NB-IOT communication module, if yes, sending data through the NB-IOT communication module and waiting for a response signal, when the response signal is received within the preset time, continuing to send the data, if no or no response signal is received, judging whether the signal meets the transmission requirement or not through a mobile cellular network communication module, if so, sending data through the communication module and waiting for a response signal, when the response signal is received, continuously sending the data, otherwise, sending the data through a Beidou short message communication module. The system can automatically switch a data transmission mode according to a current NB-IOT network service signal and a mobile cellular network signal, and preferentially adopts NB-IOT to upload data so as to save power consumption and improve communication stability, and secondly, uploading the data to a mobile cellular network, otherwise, uploading the data by adopting a Beidou short message to ensure that the data is uploaded in time.

Description

technical field [0001] The present invention relates to the technical field of remote terminal control systems, in particular to a remote terminal control system capable of intelligently switching data transmission modes and a storage medium. Background technique [0002] In long-term monitoring projects such as engineering and scientific research, it is necessary to monitor monitoring objects such as strain, stress, displacement, deformation, etc., and different sensors will be used for different monitoring objects. RTU (remote terminal control system) collects the sensor and analyzes the data, and finally uploads it to the server, so as to realize the automatic monitoring, display and analysis of the data. [0003] When the RTU (remote terminal control system) currently on the market uploads data to the server, most of them use the mobile cellular communication network for data transmission. The power consumption of mobile cellular network services is high, the signal tra...
