Description

A kind of tank capacity detection device
Technical field
The utility model relates to a kind of detection device, especially a kind of tank capacity detection device belongs to measurement monitoring Equipment design and manufacturing technology field.
Background technique
Maximum difference is that the oil storage tank of skid-mounted type gas station is directly pacified between skid-mounted type gas station and conventional gasoline station It is placed on ground, and the oil storage tank at conventional gasoline station is then embedded in underground.During oil storage, oil density can be with outside Temperature change and change, therefore existing oil storage tank all uses V25 density to be multiplied to obtain quality with volume.This way the temperature difference compared with When big, being easy to appear the practical oil reserve of oil storage tank, there are relatively large deviations with tank gage height calculated value.In addition, if adding Fuel charger breaks down during oil, finds not in time, and metering inaccuracy also will affect the accuracy of tank capacity.It is long-term tired Product brings the deviation of tank capacity excessive, will cause operator and holds inaccuracy to tank capacity, thus to oil product operation The problems such as bringing adverse effect.It is therefore desirable to be improved the prior art.
Summary of the invention
It is easy to be influenced by extraneous factor to solve the oil mass measuring and calculating mode of existing oil storage tank use, and occurs what measuring and calculating was not allowed Problem, the utility model provide a kind of tank capacity detection device.
The utility model is completed by following technical proposal: a kind of tank capacity detection device, including oil storage tank, special Sign is to be respectively equipped with digital temperature meter, liquidometer and digital densitometer on oil storage tank, in which: digital temperature meter, liquid Position meter and digital densitometer pass through conducting wire respectively and are connected with signal/data converter, signal/data converter and controller phase Even, it is sent to will pass through digital temperature meter, liquidometer and digital densitometer for the temperature, liquid level, density signal of acquisition Signal/data converter is sent to controller and is counted after temperature, liquid level, density analog signal are converted to digital signal It calculates, to obtain true oil storage magnitude, guarantees the regular supply of oil plant.
Signal/the data converter is conventional equipment, and input terminal is by signal transmssion line successively and on oil storage tank Digital temperature meter, liquidometer are connected with digital densitometer, and output end is connected by cable with controller.
The controller is model STM32F103 chip, and pin 8 therein, pin 9 are turned by signal/data respectively Parallel operation 6 is connected with corresponding digital temperature meter access end 8, liquidometer access end 9, and pin 42, pin 43 pass through signal/data Converter 6 is connected with corresponding digital densitometer access end 11,12, after obtaining temperature, liquid level, density data, passes through The software for calculation of load on the chip, calculates oil mass data, obtains true, effective oil storage magnitude, guarantees oil plant Regular supply.
The utility model has following advantages and effect: using the above scheme, it is convenient to by being arranged on oil storage tank Digital temperature meter, liquidometer and digital densitometer, and by set digital temperature meter, liquidometer and digital density Meter is connected by signal transmssion line with signal/data converter, then passes through cable for signal/data converter and controller phase Even, after temperature collection, liquid level, density signal are converted into digital signal, controller is sent to be calculated, to obtain true Real, effective, accurate oil storage magnitude, guarantees the regular supply of oil plant.The utility model structure is simple, easy to use, accuracy It is high.An actually ideal tank capacity detection device.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model;
Fig. 2 is controller circuitry figure;
Fig. 3 is thermometer access circuit figure;
Fig. 4 is tank gage access circuit figure;
Fig. 5 is densitometer access circuit figure.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
Tank capacity detection device provided by the utility model, including oil storage tank 1, are respectively equipped with number on oil storage tank 1 Word formula thermometer 2, liquidometer 3 and digital densitometer 4, in which: digital temperature meter 2, liquidometer 3 and digital densitometer 4 It is connected respectively with signal/data converter 6, signal/data converter 6 is connected with controller 8;Signal/the data converter 6 For conventional equipment, input terminal passes through signal transmssion line 5 and digital temperature meter 2 corresponding on oil storage tank 1, liquidometer 3 respectively It is connected with digital densitometer 4, output end is connected by cable 7 with controller 8;The controller 8 is conventional equipment, and Software for calculation is installed on the controller.
The controller is model STM32F103 chip, and pin 8 therein, pin 9 are turned by signal/data respectively Parallel operation 6 is connected with corresponding digital temperature meter access end 8, liquidometer access end 9, and pin 42, pin 43 pass through signal/data Converter 6 is connected with corresponding digital densitometer access end 11,12, after obtaining temperature, liquid level, density data, passes through The software for calculation of load on the chip, calculates oil mass data.
When work, by digital temperature meter 2, liquidometer 3 and digital densitometer 4 in due course by collected oil storage tank 1 The temperature of interior oil plant, liquid level, density analog signal are sent to after signal/data converter 6 is converted to digital signal, are sent to control Device 8 processed is calculated, to obtain true, effective, accurate oil storage magnitude, guarantees the regular supply of oil plant.
