Abstract

The invention discloses a liquid level instrument communication module for a skid-mounted oil tank and a communication method. The liquid level instrument communication module comprises a data receiving unit, a data processing unit, a 4G data transmission unit and a network communication switching unit. The network communication switching unit comprises an analog electronic switch and two paths of Internet of Things card slots; the data receiving unit is in communication connection with a liquid level instrument sensor of the skid-mounted oil tank; the data receiving unit, the data processing unit and the 4G data transmission unit are connected in sequence; and the 4G data transmission unit is in communication connection with a background system. According to the invention, the double internet of things cards are additionally arranged in the liquid level instrument communication module. The situation that the network communication quality is poor in the actual installation environment is handled, accurate data transmission is achieved through the RS232 communication technology and the RS485 communication technology, and therefore long-time high-quality stable operation of the liquid level instrument communication module is achieved. Meanwhile, the oil quantity information in the skid-mounted oil tank is timely and accurately transmitted.

Description

technical field [0001] The invention relates to the technical field of liquid level gauge communication, in particular to a liquid level gauge communication module and a communication method for skid-mounted oil tanks. Background technique [0002] In order to understand the oil storage situation of the skid-mounted oil tank, the data of the liquid level sensor of the skid-mounted oil tank is usually transmitted to the background system for processing. However, the existing technology mainly relies on the 4G network for data interaction with the background system, which requires good network conditions at the installation site, but the actual situation is complex and changeable, which may lead to communication disconnection and inaccurate data transmission. [0003] In view of this, this application is proposed. Contents of the invention [0004] The technical problem to be solved by the present invention is: the existing technology mainly relies on the 4G network for dat...
