Embodiment 1

[0032] Example 1: The structure of the present invention is as figure 1 with figure 2 As shown, the software flow is as image 3 Shown. It is composed of oil inlet pipe 1, filter 2, oil pump 3, manual valve 4, one-way valve 5, flow meter 6, solenoid valve 7, automatic loading control cabinet 15 and microcomputer control device 16, oil pump 3, flow meter 6 The solenoid valve 7 is connected to the automatic loading control cabinet 15, the automatic loading control cabinet 15 is connected to the microcomputer control device 16, and the microcomputer control device 16 is connected to the Ethernet cable 18; the automatic loading control cabinet 15 is connected to the oil tanker 9 There is an anti-static device 11 between.

[0033] The anti-static device is composed of an explosion-proof contact suction cup switch K, two triodes T1 and T2, and a photoelectric coupler TLP521. The explosion-proof contact suction cup switch K is adsorbed on the oil tank of the tanker, and the switch K and...

Embodiment 2

[0047] Embodiment 2: The device and method of the present invention are the same as Embodiment 1, except that the specific steps are as follows:

[0048] (1) Confirm that the initial correction value a of the oil load before starting the device is 18kg;

[0049] (2) Input the initial correction value a (18kg) of the oil filling quantity and the initial data of the predetermined oil filling quantity into the computer;

[0050] (3) The computer sends out the fueling instruction, and the oil pump and solenoid valve are activated through the automatic control cabinet to complete the fueling process of the fuel tanker;

[0051] (4) If the actual error between the actual fuel volume of the first vehicle and the predetermined fuel volume is 24kg, which is greater than a (18kg), then re-determine the correction value b as 9kg;

[0052] (5). Input the correction value b (9kg) and the initial data of the predetermined oil volume into the computer, and repeat step (3);

[0053] (6). If the a...

Abstract

The invention is a device controls the oil tank in-loading of the light oil and its control method. The device consists of intake pipe, filter, oil pump, manual valve, single acting valve, flowmeter. Besides there are also solenoid valve, automatic loading control counter, computer control device, and antistatic device. The oil pump, flowmeter and the solenoid valve is connected to the automatic loading control counter which connected to the Ethernet through the computer control device and cable. The antistatic device is installed between the counter and the oil tanker. Input the initial date of revising intaking amount and the reserved amount of oil by using the device to the computer, the device will pump out oil at the amount calculated. Adjust the revising amounting according to errors of each loading so to meet the need of controlling loading accuracy. The invention is rationally designed, easily produced, conveniently applied, well extended and precisely controlled.

Description

(1) Technical field [0001] The invention relates to a control method for the automatic loading of liquid products, in particular to a control device and a control method for the loading of light oil products. (2) Background technology [0002] In the late 1990s, the dominant industrial process control was the wide application of DCS (distributed control system). With the rapid development of computer network technology, and at the same time due to the further complexity of the production process and control system, people apply computer network technology to the data transmission between the control front-end computer and the front-end computer and the upper computer. The computer still completes its own control functions, but the data transmission between it and the upper computer is realized by a computer network. The upper computer has increased the system configuration function and the network supporting function. The DCS system is the application of computer network technolo...
