Multi-valve remote control system and remote control method based on Beidou short message

Abstract

The invention discloses a multi-valve remote control system and a remote control method based on Beidou short messages, and mainly solves the problem that bidirectional communication between a user and multiple valves and between the user and a sensor cannot be realized without network coverage in the prior art. The system comprises a programmable control chip, an electromagnetic relay, current control equipment, an antenna, keys and an LCD (liquid crystal display), five interfaces are arranged outside the programmable control chip and are respectively connected with the electromagnetic relay, the current control equipment, the external switch valve, the Beidou transceiver and the 5G communication module; eight different functional modules are arranged in the programmable control chip, and the functional modules are matched with equipment and parts connected with all ports of the programmable control chip to obtain valve information of an industrial site. According to the invention, the reliability of Beidou short message transmission is improved, bidirectional communication of multiple devices by a user and remote control and information acquisition of an industrial valve can be realized, and the system can be used for remote control of an oil and gas pipeline valve and real-time monitoring of field information.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and in particular relates to a transmission protocol between valve remote control and information acquisition, which can be used for remote control of oil and gas pipeline valves and real-time monitoring of on-site information. [0002] technical background [0003] Most of the current industrial valves use on-site manual control, and the main remote control method is to use 4G network, etc. In practice, valves may be placed in remote or sparsely populated places. If there is no base station signal coverage in the local area, there will be no network. In the case of remote control and communication, however, the amount of actual communication data for industrial valve control is small, and laying network cables or erecting base stations for it will greatly increase the cost. [0004] The Beidou short-message communication technology is adopted, which directly relies on satellite communic...

AI Technical Summary

Problems solved by technology

However, due to its lack of data transmission coordination in the case of multiple sensors and multiple valves, it is easy to cause data congestion and the reliability of communication cannot be guaranteed, and it lacks a processing mechanism for message loss. Reliable communication protocol for multiple devices

[0008] In addition, most of the communication methods of Beidou short messages in the above-mentioned prior art do not have a unified plan for the communication protocol format, and it is difficult to realize two-way communication from one user to multiple devices, and the reliability of communication cannot be guaranteed
