Hereinafter will describe fourth embodiment of the invention.
Underground buried object management system according to the fourth embodiment of the present invention is made up of an elastic wave generation unit and an elastic wave probe unit.The elastic wave generation unit comprises an oscillating plate 414, is used for producing an elastic wave by vibration; A hammer 413 is used to impact oscillating plate 414; An oscillator 412 is used to produce and changes magnetic field and hammers 413 vibration into shape to cause; And a power supply, be used to oscillator 412 that electric current is provided.And the elastic wave generation unit is installed in the pipeline with certain shape.In addition, probe unit comprises: a signal processing unit 415, and when arriving the face of land after elastic wave diffuses through as the soil of medium, this signal processing unit is used to survey the elastic wave sent from oscillating plate and converts the elastic wave that detects to electric signal; A signal processing unit 416 is used to handle the electric signal that transmits from the elastic wave receiver; And a computing unit 417, be used for the electric signal that analyzing and processing is crossed, so that calculate the position of buried pipes.
In the present invention, signal processing unit is processed the signal that transmits by amplification and filtering usually.And power supply can be used to produce the alternating current of certain frequency and the fluctuation generator that this alternating current reaches oscillator is formed by a current supply device that is used to provide certain electric current and one.The elastic wave that the fluctuation that this kind structure forms causes makes the elastic wave that is produced by the elastic wave generation unit can be easy to be distinguished from noise.
The present invention is described in detail with reference to Fig. 5 below.
At first explain basic problem of the present invention.The elastic wave generation unit of underground buried object management system of the present invention must be embedded in underground with pipeline together.In other words, in the stage of building pipeline, just elastic wave generation unit (at least one) should be sticked to the surface of pipeline with certain interval.Usually, for preparing power lead to the power supply of elastic wave generation unit.And for the needs for definite buried pipes position, in suitable zone, electric current is applied to attached to the elastic wave generation unit on the pipeline, so that the measuring channel position.
Usually, elastic wave mainly is a kind of ripple of sound wave level, and it is propagated in the elasticity medium by causing the vibration of forming particulate.Elastic wave has comprised the characteristic of medium and wave source, and the information of relevant wave source can obtain by the elastic wave signal that analysis receives, and it is based on an equation about the ripple of elastic solid (Hookean body), and this equation is that uniform elastic solid (Hookean body) is a prerequisite with the hypothesis medium.The excusing from death wave detector of applying piezoelectric phenomenon is normally used for surveying elastic wave.Yet mechanical type impacts or electromagnetic technique equally also can be used.
Figure 5 shows that and be used to locate elastic wave vibration of buried pipes and the structural representation of measuring system according to the fourth embodiment of the present invention.

According to the different shape of magnetic wave, the magnetic field that oscillator 412 produces applies power to impact oscillating plate to hammering 413 into shape.In other words, the magnetic wave that changing attracts hammer 413 impacting oscillating plate, and then separately.When electric current repeats to supply, so work and to take place repeatedly.And it has a similar structure with typical electric bell substantially.
Oscillating plate is beaten the difference of the pattern of oscillating plate according to its material, shape and hammering, produces unique elastic wave.Therefore, be changed at this oscillating plate, hammer and fluctuation generator under the situation of several different waveforms, the elastic wave shape can be adjusted, for example by adjusting vibration and hammer and according to the rhythm that impacts of fluctuation generator.For this reason, the elastic wave generation unit with by the piping erection of being buried together, these parts are set simultaneously with the environment around being suitable for can be captured to so that be different from the signal of ambient noise, with the measurement of the accurate position of carrying out buried pipes.
After all, the AC ripple of fluctuation generator generation will be reflected to elastic wave.Pass through to propagate up to arriving ground from the elastic wave that oscillating plate produces as the soil of medium.What significantly do not express among the figure is, because will be embedded in undergroundly, the elastic wave generation unit needs with a container pack.There is a space in this container, hammers 413 there into shape and can produce vibration.Oscillating plate passes to soil as medium attached to the surface of the surface of container and container with elastic wave.Choosing is done the material of this container and is wanted anticorrosion and anti-oxidant, also will consider vibration and noise that surrounding environment produces during design.And, when design containers, should consider the grounding requirement of the soil relevant with power supply.
In the drawings, be installed in the above part in ground and constituted probe unit of the present invention.Probe unit comprises: the sensor as the elastic wave receiver is used to survey elastic wave.Sensor detects elastic wave on the ground and the elastic wave acoustic pressure is changed to produce elastomer signal.Once the basic test in order to the timing that obtains appropriate sensitivity may be necessary.If use a vibration level table as the elastic wave receiver, but survey frequency scope is used to measure the vibration that do not have vibration source and according to the position of the wave source that vibration source is arranged and the sound pressure level of the degree of depth at 2Hz to the oscillator between the 1MHz, and when using sensor, the signal analysis of treatment facility and sensitivity can be compensated in advance.
The electric signal that elastic wave produces is handled in signal processing unit 416.The signal that obtains in the elastic wave receiver is very faint, to such an extent as to be easy to be influenced by surrounding environment.Usually finish signal Processing by carrying out amplification and filtering operation.The electric signal of crossing by signal processing unit processes is output to computing unit.Computing unit is usually by forming such as computing machine, and it is installed by using, and can calculate from the program that input signal calculates sound source position.
