Further, described LED nixie display comprises liquid level display window, volume display window, density display window and weight display window.
Further, described alarm comprises the pilot lamp of hummer and connecting luminous diode.
Further, the load button for inputting liquid level warning value is also comprised.
Further, described load button is the keyboard being placed on shell.
By such scheme, the present invention at least has the following advantages: a kind of boats and ships cargo tank liquid level emasuring device provided by the invention, liquid level and the density of fluid goods is measured by liquid level sensor and density sensor, and what calculate obtains volume and weight, more can reflect intuitively cargo tank the truth of thing of freighting; By the liquid level alarm value of setting, make liquid goods be loaded into certain altitude output alarm signal, remind personnel's goods to fill.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present invention;
Fig. 2 is work block diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
See Fig. 1 and Fig. 2, a kind of boats and ships cargo tank liquid level emasuring device of a preferred embodiment of the present invention, comprise shell (not shown), be placed on the liquid level sensor 1 of shell, be arranged on the LED nixie display 2 of case surface, be built in the single-chip microcomputer 3 of shell, A/D collector 4 and liquid level analog signal collector 5, single-chip microcomputer 3 and LED nixie display 2, A/D collector 4 is connected, liquid level analog signal collector 5 and liquid level sensor 1, A/D collector 4 is connected, above-mentioned boats and ships cargo tank liquid level emasuring device also comprises load button 6, be placed on the density sensor 10 of shell, be arranged on alarm 7 and the light beam liquid crystal display 8 of case surface, be built in the density analog signal picker 9 of shell, single-chip microcomputer 3 and load button 6, alarm 7, light beam liquid crystal display 8 is connected, density analog signal picker 9 and density sensor 10, A/D collector 4 is connected.In the present embodiment, LED nixie display 2 comprises liquid level display window 21, volume display window 22, density display window 23 and weight display window 24, alarm 7 comprises the pilot lamp of hummer and connecting luminous diode, and load button 6 is for being placed on the keyboard of shell.
Workflow of the present invention is as follows: when this device is started working, be placed in liquid level sensor 1 in cargo tank and density sensor 10 detects the liquid level of fluid goods and the parameter value of density, this parameter is sent into liquid level analog signal collector 5 and density signal collector, A/D collector 4 is sent into after converting simulating signal to, the calculating carrying out liquid level and density in single-chip microcomputer 3 sent into by A/D collector 4 after converting simulating signal to digital signal, the volume of goods is calculated by liquid level and with reference to the table of tank capacities of storage, then the weight of goods is calculated with reference to density value, liquid level, volume, density and weight all show in LED nixie display 2, very clear during use, more can reflect the truth of goods in cargo tank intuitively.Light beam liquid crystal display 8 is for simulative display liquid level, and unit is the number percent of full scale, with 9 green 1 red interval displays, reflects liquid level situation more intuitively.Meanwhile, processed to single-chip microcomputer 3 by keyboard typing liquid level alarming value, compare with the actual value of its measured value, when measured value is higher than setting value, the hummer sounding of alarm 7 and instruction pilot lamp is luminous.
In sum, this device is a kind of liquid goods measurement instrument of comparatively sense organ at present, compare other liquid goods measurement instrument, by adding density sensor 10, the density value of liquid goods can be recorded more accurately, and by calculating the weight of liquid goods, more intuitively reflect cargo tank the number of thing of freighting; Arranged by input, make liquid goods be loaded into certain altitude output alarm signal, remind personnel's goods to fill; In addition, this device also has data power down persistence, fault self-checking, automatic detection sensor short circuit and open circuit, compact structure, the advantage such as easy for installation.
The above is only the preferred embodiment of the present invention; be not limited to the present invention; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
