Quantitative distribution system of oil products

Abstract

The invention discloses a quantitative distribution system of oil products. The system realizes automatic control of quantitative distribution of oil materials. A driver manipulator is connected with an optical fiber exchange machine by an industrial Ethernet; a PLC (programmable logic controller) batch controller is also connected with the optical fiber exchange machine by the industrial Ethernet; and an oil distribution system server and an oil distribution system upper computer are connected with the optical fiber exchange machine by the industrial Ethernet in the same way. When one driver manipulator has a fault, IP addresses of PLC controllers to which other driver manipulators point are configured such that the other driver manipulators can send instructions to the PLC batch controller corresponding to the driver manipulator with the fault to enable the PLC batch controller to quantitatively control an oil distribution pipeline to distribute oil, therefore, the oil distribution operation of an oil distribution platform cannot be influenced and the normal oil distribution of an oil depot is guaranteed.

Description

technical field [0001] The invention relates to a quantitative distribution control device for oil products, in particular to a control system for quantitative distribution of oil on highway oil platforms. Background technique [0002] In the highway oil quantitative distribution system, when the oil delivery volume is close to the set value, in order to avoid damage to the valve, pipeline and equipment caused by the water hammer caused by the sudden closing of the valve, the valve needs to be closed step by step to make the oil in the pipeline The flow rate gradually decreases, so as not to cause damage to valves, pipelines and other equipment. However, the step-by-step closing of the valve will make it difficult for the dispensing system to accurately control the amount of oil delivered, and the overshoot generated during the valve closing process will directly affect the accuracy of the oil delivery. [0003] Usually, in the quantitative distribution system of highway oi...

Problems solved by technology

Since the driver operator is integrated with the fuel delivery controller, once the driver operator fails, the corresponding fuel delivery controller will not be able to work, which will cause the fuel delivery equipment controlled by the fuel delivery controller to fail to work. bit can't get oily

And because one oil delivery controller often needs to control the work of multiple oil delivery devices, once the driver's operator fails, it will cause multiple oil delivery stations to be unable to deliver oil, thus affecting the oil delivery capacity and efficiency of the oil depot

Especially for oil depots, there are many vehicles that lift oil every day, and the oil delivery load of the oil platform is very large. Once the oil delivery platform fails to work normally, it may lead to a backlog of oil delivery vehicles in the oil depot, and the oil delivery time of the oil trucks will be shortened. Prolonged, seriously affecting oil hair efficiency

In addition, the driver's manipulator, fuel controller and the equipment in the central control room are connected through RS485 communication cables. Because the lightning protection of RS485 communication cables is poor, it is easy to cause lightning strike failures
