Description
Technical field:
The utility model relates to warning device, relates in particular to storage tank ultrasound wave full level alarm instrument.
Background technology:
Storage tank is the Fuel Tanking Unit that oil, chemical system generally use, and for preventing the storage tank roof fall, need upper limit warning device be installed on the top of jar.The storage tank upper limit alarm adopts float switch more, and float switch is comparatively suitable for dome-roof tank.And when being used for floating roof tank, because pontoon moves below ball float for a long time, if cold weather, ball float position temperature is lower, when idol once oil level rise to ball float when above, crude oil can condense at the ball float position, makes the ball float warning device malfunctioning, and warning device tends to cause tremendous loss after malfunctioning.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of storage tank ultrasound wave full level alarm instrument is provided, and with low cost, miniaturization and high reliability, guarantees the security of operation of storage tank.
Storage tank ultrasound wave full level alarm instrument described in the utility model includes radiating circuit, pulse oscillating circuit, C8051F007 embedded scm, jtag interface, setting button, apparatus for shaping, filter amplification circuit, detecting circuit, pontoon, Pt100 thermal resistance temperature measurement circuit, resistance/voltage changer and alarm output device and forms.Said C8051F007 embedded scm is the core members of storage tank ultrasound wave full level alarm instrument described in the utility model, the low-power-consumption embedded single-chip microcomputer C8051F007 that adopts U.S. west lattice Nores (cygnal) company to produce.The output of said C8051F007 embedded scm subtend pontoon is connected with the pulse oscillating circuit, and the pulse oscillating circuit is connected with radiating circuit again, is connected with pontoon by the radiating circuit ultrasonic waves transmitted.The ultrasound wave that feeds back through pontoon is delivered to detecting circuit, connects filter amplification circuit behind the detecting circuit, connects apparatus for shaping after the filter amplification circuit, and apparatus for shaping connects the C8051F007 embedded scm again.Pt100 thermal resistance temperature measurement circuit connects resistance/voltage changer, and resistance/voltage changer inserts the C8051F007 embedded scm again.The opposite side of C8051F007 embedded scm is provided with jtag interface, can be used for on-line debugging and program upgrade at full speed.Arranged side by side with said jtag interface, also be provided with and set button and alarm output device.
Storage tank ultrasound wave full level alarm instrument described in the utility model, one-piece construction is simple, and volume is little, and cost and operating cost are low.Both applicable to dome-roof tank, again applicable to floating roof tank.Because ultrasound wave is insensitive to color, illuminance, electromagnetic field, applicable to detecting transparent and translucent object, can under rugged surroundings such as night, smog or dust, electromagnetic interference (EMI) are strong, work; Because ultrasonic propagation velocity is low, can directly measure nearer target besides.
