Abstract
The invention relates to an oiling measuring and monitoring system for a railway tank wagon. The system is composed of a low-pressure control cabinet 1, a gauge controller 2, a multiport valve controller 3, a PLC 4, an upper computer 5, a boiler monitoring system 6, a transfer pump mass flowmeter 7 and an oil tank liquidometer 8 and is characterized in that the gauge controller 2 and the multiport valve controller 3 are arranged on the low-pressure control cabinet 1 and then connected with the PLC 4 inside the cabinet through an MOUDBU protocol and an RS485 interface respectively. The system has the advantages that all equipment on site can be monitored, operated and controlled through the upper computer in a duty room, oil filling level error is controlled to be within a small range, and management level and working efficiency are improved.
Description
Technical field
The present invention relates to a kind of rail tank car oiling measurement monitoring system, be mainly used in crude oil measurement switching automation control system, belong to technical field of industrial automatic control.
background technology
Current domestic rail tank car is plank road opening conduits valve on a people in the oiling process of refinery, and another people turns oil pump in terrestrial operation, the number of injection flow visually result and mass flowmeter read be worth.This oiling mode makes operating personal ascend operation more dangerous; Injection flow error is comparatively large simultaneously, there will be the deviation of 2 tons.
Summary of the invention
Object of the present invention provides a kind of deficiency overcoming above technology, and provide a kind of rail tank car oiling measurement monitoring system to make to obtain injection flow intuitively during operation, operating personal is without ascend operation.Be achieved through the following technical solutions for achieving the above object: the present invention relates to a kind of rail tank car oiling measurement monitoring system, by low-voltage power distributing cabinet 1, metering device controller 2, multiport valve controller 3, PLC 4, upper computer 5, Boiler Monitoring System 6, turn oil pump mass flowmeter 7, oil tank level meter 8 forms, it is characterized in that metering device controller 2 and multiport valve controller 3 layout are at low-voltage power distributing cabinet 1, then linked together with the PLC 4 in cabinet respectively by MOUDBU agreement and RS485 interface.Described Boiler Monitoring System 6, turn oil pump mass flowmeter 7, the monitoring parameter of oil tank level meter 8 is directly connected in PLC 4.Described PLC 4 is connected with upper computer 5 by RS485 interface.
the invention has the beneficial effects as follows:
1, just can be monitored by upper computer in watch house, operate, control on-the-spot all devices;
2, make injection flow control errors in more among a small circle, raise the management level and work efficiency.
description of drawings 1 is a kind of rail tank car oiling measurement monitoring system schematic diagram:
1-low-voltage power distributing cabinet 2-metering device controller 3-multiport valve controller 4-PLC controller 5-upper computer 6-Boiler Monitoring System 7-turns oil pump mass flowmeter 8-oil tank level meter.
detailed description of the invention explanation
embodiment is told about below in conjunction with Fig. 1:
the effect of embodiment 1 one kinds of rail tank car oiling measurement monitoring system compositions and each parts:
The present invention relates to a kind of rail tank car oiling measurement monitoring system, by low-voltage power distributing cabinet 1, metering device controller 2, multiport valve controller 3, PLC 4, upper computer 5, Boiler Monitoring System 6, turn oil pump mass flowmeter 7, oil tank level meter 8 forms, it is characterized in that metering device controller 2 and multiport valve controller 3 layout are at low-voltage power distributing cabinet 1, then linked together with the PLC 4 in cabinet respectively by MOUDBU agreement and RS485 interface.Described Boiler Monitoring System 6, turn oil pump mass flowmeter 7, the monitoring parameter of oil tank level meter 8 is directly connected in PLC 4.Described PLC 4 is connected with upper computer 5 by RS485 interface.
the working process of embodiment 2 one kinds of rail tank car oiling measurement monitoring systems:
During oiling, under the man-hole opening of rail tank car being aimed at the fuel feeding valve of oiling tube, system starts under the operation of PLC 4, and oil level, by the detection turning oil pump mass flowmeter 7, oil tank level meter 8, is injected into assigned position by metering device controller 2, multiport valve controller 3.
Certainly; above-mentioned explanation is not limitation of the present invention; the present invention is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
