Embodiment 1

[0041] Example 1: Take the sale of liquefied petroleum gas by automobile as an example

[0042] Such as image 3 As shown, the customer takes the product delivery note printed by the sales system (ERP system or the local sales management system of the regional branch) to the operating room of the oil delivery station to issue the product delivery note, and the operator of the oil delivery machine automatically distributes oil in quantitative quantities according to the delivery note number. Enter the bill of lading number or select the same bill of lading number according to the type of the bill of lading number on the control system of the vehicle, and the control system of automatic quantitative fuel delivery and loading will transfer the key data in the bill of lading such as the bill of lading number, vehicle number, The information such as lifting capacity is stored in the database. Since the maximum safe filling capacity of each transport vehicle has been entered into th...

Embodiment 2

[0043] Example 2: Take the sale of diesel by railway as an example

[0044] Such as Figure 4 As shown, diesel is sold as a unified distribution, and no paper bill of lading is required. The railway tank car is transferred to the loading platform through the sales management system of the regional branch. When the tank car enters the factory, the train number and model information of each tank car are automatically collected and stored in the database through the railway tank car number recognition system, and the automatic quantitative distribution The control system of oil loading assigns each tank car to correspond to the corresponding oil distribution crane position, and the control system of automatic quantitative oil distribution and loading automatically calculates the standard filling amount according to the vehicle model information of each tank car, and puts the vehicle number and standard filling The amount is downloaded to the PLC operation terminal of the oil gen...

Abstract

An embodiment of the invention discloses a method and a system for controlling oil distribution and vehicle loading automatically and quantitatively. The method comprises the steps as follows: lading bill information comprising a lading bill number, a vehicle number and a pre-lading quantity of a to-be-loaded vehicle is obtained; whether the pre-lading quantity exceeds the pre-stored maximum safety filling quantity is judged according to the vehicle number; if the pre-lading quantity does not exceed the pre-stored maximum safety filling quantity, the lading bill number, the vehicle number, the pre-lading quantity and the maximum safety filling quantity are sent to an oil distribution machine PLC (programmable logic controller) system through an OPC (OLE for Process Control) interface; the oil distribution machine PLC system controls oil distribution according to the pre-lading quantity and returns to an actual oil distribution quality; and the OPC interface receives the actual oil distribution quality and stores the actual oil distribution quality. According to the method and the system for controlling oil distribution and vehicle loading automatically and quantitatively, an oil distribution quality is not required to be input manually, the accuracy of the oil distribution quality is guaranteed, and the pre-lading quantity is restrained by the maximum safety filling quantity, so that an actual filling quantity cannot exceed the maximum safety filling quantity, and the safety of an oil product in a transportation process is guaranteed.

Description

technical field [0001] The invention relates to a vehicle automatic fuel delivery and loading technology, in particular to a control method and system for automatic quantitative fuel delivery and loading. Background technique [0002] The current oil generator system adopts an advanced PLC control system, and the measurement method is also accurate flow meter measurement, and combined with the linkage technology of the numerical control valve and the oil pump, then the quantitative hair can be realized by inputting the amount of oil on the PLC control terminal. Oil. [0003] However, the existing PLC control system is independent. When filling oil, the operator needs to manually input the oil delivery amount on the delivery machine according to the pre-lifted amount on the customer's bill of lading. Therefore, if human error will cause excessive delivery of oil, it is easy to cause a fire hazard; in addition , if the advance amount of the bill of lading is greater than the...
