Abstract
The invention provides a portable multifunctional acoustic beacon detection device. The device includes an acoustic beacon mounter, an internal detection circuit, an information interaction unit and a portable multimeter. The internal detection circuit of the detection device is installed in a box; an acoustic beacon mounting hole and the information interaction unit are designed on a panel; the portable multimeter is separately stored in a pocket of a box body; and the detection device is externally connected with a power supply. The effects and benefits of the portable multifunctional acoustic beacon detection device are that the device is small and exquisite and portable, has many test items, and can enable a user to detect an acoustic beacon on a using site, thereby obtaining the electric quantity and working state of the acoustic beacon without returning the acoustic beacon to the factory.
Description
Technical field
The invention belongs to Underwater Acoustics Engineering technical field, it relates to detect device to acoustic marker, it is related specifically to the acoustic marker detection device of a kind of portable multi-function.
Technical background
Acoustic marker is a kind of device that can send acoustical signal in water, is commonly used in the water surface, the equipment of underwater operation and personnel. The working order of detection acoustic marker, is generally use professional test equipment to carry out in manufacturer, does not have the instrumentation that can test acoustic beacon in user's hand. If user wants detection, whether acoustic beacon is in standard state, can only use volt ohm-milliammeter test acoustic beacon voltage or be detected by acoustic beacon return-to-factory. The former can only judge whether acoustic beacon has electricity, cannot judge its working order; The latter is by the time and efforts of at substantial.
Summary of the invention
It is an object of the invention to provide a kind of portable multi-function acoustic marker detection device, the working order of acoustic beacon can be detected by this device at scene, this device can the electricity of on-line checkingi acoustic beacon, source level, frequency, signal pulsewidth, can also intuitively be shown the acoustical signal of acoustic beacon by loud speaker, solve the difficult problem that acoustic marker user does not have portable multi-function acoustic marker detection device.
The solution of the present invention is:
A kind of portable multi-function acoustic marker detection device, comprises acoustic marker erector, internal detection circuitry, information interaction unit and Portable universal meter; The internal detection circuitry of detection device is arranged on device inside; Acoustic marker open holes and information interaction unit are outside at device; Portable universal meter is singly deposited separately in device, detection device external source.
Described internal detection circuitry is that bandpass filter connects amplification circuit, connects thereafter a/d converter and digital signal processor, arranges a subcircuit in digital signal processor, and a road is connected to threshold controller and clock count device; Another road is connected to signal amplitude detection device and comparer. After beacon signal enters signal processor unit, process by amplifying circuit and A/D converter circuit, detect respectively through subcircuit afterwards, it may also be useful to the pulsewidth of threshold controller and clock count device detected beacon signals and frequency; Use signal comparer standard signal maker and beacon signal to be compared, obtain the source level of signal.
There are beacon open holes, signal trigger device, Signal reception device in described underwater sound letter erector inside, and beacon open holes perforate is on panel, and signal trigger device is arranged on the lower section of beacon open holes, and Signal reception device is connected with internal detection circuitry.
Described information interaction unit is made up of touch LED display and loud speaker, and the instruction of user is transferred in master control unit by information interaction unit.
Described Portable universal meter independently leave in detection device in, when acoustic beacon be positioned at small space cannot take off time, it may also be useful to the electricity of Portable universal meter on-line checkingi acoustic beacon.
The effect of the present invention and benefit are that this device is small and exquisite, portable, test item is many, it is possible to allow family be detected by acoustic marker at use scene, when Bu Fan factory, know electricity and the working order of acoustic marker.
Accompanying drawing explanation
Fig. 1 is by the vertical view of the application, and top is divided into inside case lid, lower part bit manipulation panel.
Fig. 2 is the front view after the application removes outer-layer box body.
Fig. 3 is that internal detection circuitry part realizes schematic diagram.
In figure: 1 Portable universal meter; 2 acoustic beacon erectors; 3 acoustic markers; 4 internal detection circuitry; 5 information interaction unit.
Embodiment
Below in conjunction with accompanying drawing, the application is described in further detail:
In Fig. 1,2, acoustic marker 3 water switch is downward, and in the beacon open holes of insertion acoustic beacon erector 2, beacon trigger device triggers acoustic marker water switch and works on power, and Signal reception device receives underwater sound signal, and is transferred in internal detection circuitry 4; Detected result is passed through information interaction unit and user interactions by internal detection circuitry. Portable universal meter 1 leaves in the pocket of box cover, it is possible to take out use at any time.
In figure 3, by amplifying, circuit enters in bandpass filter signal, and bandpass filter connects a/d converter and digital signal processor, arranges a subcircuit in digital signal processor, and a road is connected to threshold controller and clock count device; Another road is connected to signal amplitude detection device and comparer, and high precision clock connects comparer. Acoustic marker signal enters signal processing device postpone, and first through amplifying circuit amplification process, by band-pass filter to unnecessary signal, signal, after a/d converter 4 enters digital signal processor, carries out classification process. Digital signal processor arranges a subcircuit, is calculated pulsewidth and the frequency of signal by threshold controller and clock count device; Use comparer 9 to compare with high precision clock by the signal after signal amplitude detection device amplification, obtain the source level of signal.
