Problems solved by technology

It is not difficult to see that the bottleneck of my country's gas station information management is the lack of definition and scope of gas station information management; second, the communication protocols of control equipment such as oil machines are diversified and not open, and basic data collection is difficult
Among them, the incompatibility between new and old equipment caused by protocol diversification and non-openness is the biggest difficulty

Abstract

The invention relates to the field of information automated management used for refueling devices of a gas station, and discloses a multiprotocol oil machine communication concentrator comprising a bus control device, same-direction bus driving devices, a reverse-direction bus driving device, optical coupler isolation devices and a communication interface device. The bus control device is respectively connected with the same-direction bus driving devices and the reverse-direction bus driving device. The optical coupler isolation devices are connected between the same-direction bus driving devices and the communication interface device and connected between the reverse-direction bus driving device and the communication interface device respectively. The invention also discloses a multiprotocol oil machine communication method. Advantages of the multiprotocol oil machine communication concentrator are that the multiprotocol oil machine communication concentrator is simple in circuit structure, great in compatibility, compatible with various existing communication protocols, higher in anti-interference capability, high in security and higher in application value.

Description

technical field [0001] The invention relates to the field of information automation for refueling devices at gas stations, in particular to a multi-protocol fusion fuel-machine communication hub device and a multi-protocol fuel-machine communication method. Background technique [0002] Petroleum is a strategic resource that is related to national economy, people's livelihood and national defense security. With the rapid development of China's oil product retail industry and the active influx of foreign oil companies, the necessity and importance of gas station network management has become increasingly prominent. The information center needs to determine the production of petrochemical products of petrochemical enterprises through the analysis of real-time information, and reasonably allocate the quantity of petrochemical products for each gas station or regional fuel center. It is not difficult to see the importance of informatization in petrochemical enterprises. [000...
