Abstract

The utility model discloses an ultrasonic level gauge. An ultrasonic probe which is capable of transmitting ultrasonic waves and calculating the liquid level distance of liquid according to the transmitted and received time difference of the reflective waves is connected with an ultrasonic instrument. The ultrasonic level gauge is connected with a GPS (Global Positioning System) through an Rs232 communication interface; the GPS is connected with a GPS server through a wireless signal; the GPS server is connected to a database through a network TCP/IP (Transmission Control Protocol/Internet Protocol); and the database is connected to a client through a network TCP/IP.

Description

Ultrasonic level gage

Technical field

The utility model relates to a kind of gasoline of motor fuel tank liquid level emasuring device field, relates in particular to a kind of by ultrasonic technology, by GPS positioning system ultrasonic level gage connected to the network.

Background technology

At present, the liquid level that adopts applying ultrasonic lever meter to measure liquid to change at any time is widely used, and ultrasonic level gage is the digital liquid level instrument by microprocessor control.Ultrasonic pulse is sent by sensor (transducer) in measurement, sound wave is received or ultrasonic receiver by same sensor after the liquid surface reflection, convert electric signal to by piezoelectric crystal or magnetostrictive device, and by the distance of the time calculating sensor between the transmitting and receiving of sound wave to the fluid to be measured surface.Because adopt non-contacting measurement, measured medium is restricted hardly, can be widely used in the measurement of various liquid and solid material height.

Ultrasonic level gage is connected by sensor device in the prior art, sensor receive data information transfer to the receiver of Instrument connection, receiver receives data transmission and shows to instrument.

The utility model content

It is a kind of by ultrasonic technology, by GPS positioning system ultrasonic level gage connected to the network that the technical problems to be solved in the utility model has been to provide.

For solving the problems of the technologies described above, the utility model is realized by following scheme: ultrasonic level gage, by sending the ultrasonic probe of hyperacoustic ultrasonic probe by the liquid level distance that sends to reflection wave mistiming of receiving, calculate liquid, be connected with ultrasonic instrument; This ultrasonic level gage connects the GPS positioning system by the Rs232 communication interface, and the GPS positioning system connects the GPS server with wireless signal.

Further, described GPS server is connected to database by network TCP/IP; Described database is connected to client by network TCP/IP.

The utility model has the advantages that: this ultrasonic level gage utilizes GPS positioning system and Internet Transmission, with the data transfer of ultrasonic level gage on instrument.

Description of drawings

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the utility model applying ultrasonic lever meter to measure liquid level principle schematic;

Fig. 2 is that the utility model shows the liquid level distance by GPS and Internet Transmission.

Embodiment

As shown in Figure 1 and Figure 2, ultrasonic level gage by sending the ultrasonic probe 2 of hyperacoustic ultrasonic probe 2 by the liquid level distance that sends to reflection wave mistiming of receiving, calculate liquid 3, is connected with ultrasonic instrument 1; Ultrasonic probe 2 is from liquid one plane emission ultrasound wave, ultrasound wave is reflected back ultrasonic probe 2 through another plane of liquid, and ultrasonic probe 2 receives reflection wave, a mistiming of send and receive, calculate the height of liquid in casing, can use following formula to calculate:

S=V×T

S: the height that is indicated as liquid;

V: represent the speed that ultrasound wave moves in liquid;

T: expression ultrasonic probe 2 is from sending ultrasound wave to receiving hyperacoustic mistiming.

This ultrasonic level gage connects GPS 4 positioning systems by the Rs232 communication interface, and GPS 4 positioning systems connect GPS server 5 with wireless signal; Described GPS server 5 is connected to database 6 by network TCP/IP; Described database 6 is connected to client 7 by network TCP/IP.

The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.

Claims (2)

1. ultrasonic level gage, it is characterized in that: by sending the ultrasonic probe (2) of hyperacoustic ultrasonic probe (2) by the liquid level distance that sends to reflection wave mistiming of receiving, calculate liquid (3), be connected with ultrasonic instrument (1); This ultrasonic level gage connects GPS (4) positioning system by the Rs232 communication interface, and GPS (4) positioning system connects GPS server (5) with wireless signal.
2. according to described ultrasonic level gage claimed in claim 1, it is characterized in that: described GPS server (5) is connected to database (6) by network TCP/IP; Described database (6) is connected to client (7) by network TCP/IP.
