Description

Vector sensor self-checking device in a kind of pond
Technical field
This utility model relates to mechanics field of measuring techniques, automatically calibrates particularly to vector sensor in a kind of pond Device.
Background technology
Vector sensor is the sensor of a kind of specific type being different from tradition hydrophone, based on vector sensor The noise measurement system of composition can effectively solve the measurement of low frequency weak signal, but there is no the school of vector sensor in pond at present Standard apparatus, therefore the quality of vector sensor state is also constantly in blind area state, in order to ensure accurately may be used of vector sensor Leaning on, the research of vector sensor collimation technique is increasingly paid close attention to by relevant research worker, it is necessary to solve current China as early as possible The practical challenges of vector sensor periodic calibration in pond.
Summary of the invention
The purpose of this utility model is in order to solve the practical problem of above-mentioned existence, and spy provides vector sensing in a kind of pond Device self-checking device.
This utility model provides vector sensor self-checking device in a kind of pond, including signal generator, transmitting Circuit amplifier, transmitting transducer, pond, revolution lifting device, vector sensor to be measured, standard sound pressure hydrophone, voltmeter, Automatic electric-level monitor, preamplifier, relay and single-chip microcomputer, it is characterised in that: signal generator produces certain frequency The emitted circuit amplifier of waveform is amplified into the input of transmitting transducer, and transmitting transducer is placed on the revolution in pond On lifting device, vector sensor upper end to be measured is fixed on the revolution lifting device in pond, lower end and standard sound pressure hydrophone phase Even, vector sensor to be measured and standard sound pressure hydrophone enter into respective relay through preamplifier respectively, relay Connected state is connected with voltmeter, automatic electric-level monitor respectively by the control of single-chip microcomputer.
Further, also including that oscillograph, described oscillograph are connected with signal generator, oscillograph is monitored signal in real time and is sent out The voltage of raw device and frequency.
Further, described transmitting transducer is identical with vector sensor height in pond, is highly pond deep The half of degree.
Advantage of the present utility model: in this pond, vector sensor self-checking device is capable of vector sensing in pond Device is calibrated automatically, and calibrating installation stability is strong, and automatization level is high, and this device has certain practicality.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and this utility model is described in further detail by embodiment.
Fig. 1 is vector sensor self-checking device theory structure schematic diagram in pond.
Detailed description of the invention
Before measuring, reply vector sensor carries out surface process so that it is the fluctuating of receiving sensitivity, within 1dB, uses The alcohol water blend of 40%, after being soaked 1 minute by vector sensor, then rinses well with water, is finally putting in pond 4.Vector After sensor fully soaks several hours in pond 4, then start calibration measurement.
Vector sensor self-checking device in pond, including signal generator 1, radiating circuit amplifier 2, launches transducing Device 3, pond 4, revolution lifting device 5, vector sensor to be measured 6, standard sound pressure hydrophone 7, voltmeter 8, automatic electric-level record Instrument 9, preamplifier 10, relay 11 and single-chip microcomputer 12, wherein: the waveform that signal generator 1 produces certain frequency is emitted Circuit amplifier 2 is amplified into the input of transmitting transducer 3, and transmitting transducer 3 is placed on the revolution in pond 4 and promotes dress Putting on 5, vector sensor 6 upper end to be measured is fixed on revolution lifting device 5, and lower end is connected with standard sound pressure hydrophone 7, and transmitting is changed Energy device 3 is identical with the vector sensor 6 height in pond 4, is highly the half of the pond degree of depth.Vector sensor 6 to be measured Entering into respective relay 11 through preamplifier 10 respectively with standard sound pressure hydrophone 7, the connected state of relay 11 is subject to The control of single-chip microcomputer 12 connects respectively at voltmeter 8, automatic electric-level monitor 9.Single-chip microcomputer 12 controls relay 11 Table 8 connects, or is connected with automatic electric-level monitor 9, when being connected with voltmeter 8, and vector sensor 6 to be measured and standard sound pressure The output voltage of hydrophone 7 compares, it is achieved thereby that the calibration of vector sensor sensitivity.When with automatic electric-level monitor 9 connect time, vector sensor 6 to be measured along with revolution lifting device 5 rotation time, measure to be measured with automatic electric-level monitor 9 The output signal of vector sensor 6 and the anglec of rotation of revolution lifting device 5, it is achieved thereby that the school of vector sensor directivity Accurate, it is achieved that Automated condtrol and calibration.
In pond, vector sensor self-checking device also includes that oscillograph, oscillograph are connected with signal generator 1, oscillography Voltage and the frequency of signal generator 1 monitored in real time by device, it is ensured that the output of signal generator 1 is reliable and stable, further ensures Calibration accuracy.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate this utility model and not It is limited to the technical scheme described by this utility model embodiment, it will be understood by those within the art that, the most permissible This utility model is modified or equivalent, to reach identical technique effect;Needs are used, all in this reality as long as meeting Within novel protection domain.
