Embodiment Construction

[0048] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0049] In order to solve the problem that the smart liquid level gauge of marine LNG tanks cannot send data without GPRS or 4G full network communication signals at sea or on the river, and at the same time, to solve the monitoring of the whole transportation process of LNG tanks, it is not only necessary to consider the monitoring of marine tank data, It is also necessary to consider the data monitoring of inland waterway transportation, land transportation and other processes, and the original solution that relies solely on maritime satellite system com...

Abstract

The invention relates to an LNG (Liquefied Natural Gas) tank data transmission method based on a Beidou technology. The LNG tank data transmission method based on the Beidou technology comprises the steps of acquiring LNG tank data, selecting a LoRa communication mode, a mobile communication mode or a Beidou short message communication mode according to a current network signal receiving condition, and sending the LNG tank data to a server. The selection sequence priority of the LoRa communication mode, the mobile communication mode or the Beidou short message communication mode is as follows:the LoRa communication mode, the mobile communication mode and the Beidou short message communication mode; and a frame structure of each protocol is defined in detail. According to the scheme of theinvention, the number of equipment is reduced, and meanwhile, powerful support is provided for a power supply system, low power consumption and small size. The system integration difficulty is reduced, the cost is lowered, and the reliability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of LNG tank container data transmission, in particular to a method for transmitting LNG (Liquefied Natural Gas) tank container data based on Beidou technology. Background technique [0002] Intelligent tank level gauge is widely used in petrochemical, metallurgical machinery, water conservancy and electric power, shipbuilding, LO2, LN2, LAr, LCO2, LNG and other industries. It has local detection, GPRS or 4G full network wireless transmission, and server monitoring functions. Using the Internet of Things and cloud service technology, users can conveniently and real-time grasp and monitor the information of various sensors of containers such as storage tanks or tank containers through the web interface. [0003] With the development of mobile communication and Internet of Things technology, the requirements for the use environment of information sending devices are also getting higher and higher. The existing...
