Description
技术领域technical field
本发明涉及水下探测领域,特别涉及一种深海逆式回声测量系统及测量方法。The invention relates to the field of underwater detection, in particular to a deep-sea inverse echo measurement system and a measurement method.
背景技术Background technique
21世纪是海洋的世纪,要认识海洋、开发和利用海洋就要进行海洋调查。高新技术的海洋装备是海洋调查的重要保障。为发现海洋新现象、验证海洋新理论和满足海洋科学发展需求,在研究海域获取长周期海洋科学数据除了依靠浮标和潜标外,坐底式观测设备对获取长期现场观测数据至关重要。The 21st century is the century of the ocean. To understand the ocean, develop and utilize the ocean, it is necessary to carry out ocean surveys. High-tech marine equipment is an important guarantee for marine surveys. In order to discover new ocean phenomena, verify new ocean theories, and meet the needs of marine science development, in addition to relying on buoys and submersible buoys to obtain long-term marine scientific data in the research sea area, bottom-mounted observation equipment is essential to obtain long-term on-site observation data.
当海底的产生的声波辐射至海面并被反射回海底时,垂直声波传播的时间(Vertical Acoustic Travel Time,以下简称VATT)是一个重要的参数。我们知道,VATT变化主要遵循所测量水柱上综合温度剖面的变化规律。在一些大、中尺度洋流和锋带的应用已经证明,VATT往往可以被重新解释为位势高度(高度动态),受海流弯曲或涡的影响而不停变化。在许多地区,温度和位势高度,随时间变化的垂直剖面特征,有可能从VATT测量决定。然后从横向分离测得的数据可以估算水平梯度位势高度,可以反演计算地球自转引起的海流剖面。When the acoustic waves generated on the seabed radiate to the sea surface and are reflected back to the seabed, the vertical acoustic travel time (Vertical Acoustic Travel Time, hereinafter referred to as VATT) is an important parameter. We know that the change of VATT mainly follows the change law of the comprehensive temperature profile on the measured water column. The application of some large and mesoscale ocean currents and frontal belts has proved that VATT can often be reinterpreted as geopotential height (height dynamics), which is constantly changing due to the influence of current bending or eddies. In many regions, temperature and geopotential height, with time-varying vertical profile characteristics, may be determined from VATT measurements. Then the horizontal gradient geopotential height can be estimated from the data measured by the lateral separation, and the ocean current profile caused by the Earth's rotation can be inversely calculated.
逆式回声仪是一种安装于海底用来测量从海床到海面的垂向声传播时间的仪器。可用于监测温度结构和动态高度变化。其工作原理是在海底面布置一个换能器并向上发射声波,当发射的声波经海平面反射回接收换能器,二者之间的时间差即为VATT。观测数据可以通信上传给水面母船,也可以待逆式回声仪回收后通过读取存储设备获取,用以监测海洋主温跃层的起伏,并结合压力数据及历史水文数据利用经验公式间接推算出不同深度上的温度、盐度及密度等水体参数的变化。An inverse echometer is an instrument installed on the seabed to measure the vertical sound travel time from the seabed to the sea surface. Can be used to monitor temperature structure and dynamic altitude changes. Its working principle is to arrange a transducer on the seabed and emit sound waves upwards. When the emitted sound waves are reflected back to the receiving transducer by the sea level, the time difference between the two is VATT. The observation data can be communicated and uploaded to the surface mother ship, or can be obtained by reading the storage device after the inverse echometer is recovered, to monitor the fluctuation of the main thermocline of the ocean, and combine the pressure data and historical hydrological data with empirical formulas to indirectly calculate Changes in water parameters such as temperature, salinity and density at different depths.
目前传统的逆式回声测量系统结构简单,在深海中工作时易受海底环境的影响,布放时很难与海平面完全垂直。测量数据不够精确,测量时,混响和虚假目标(如鱼等)造成的假回波会对测量结果造成很大影响。而且,在海底工作时,各模块同时工作,对电池要求比较高,耗电量大,使用寿命短,需经常更换电池。At present, the traditional inverse echo measurement system has a simple structure and is easily affected by the seabed environment when working in the deep sea. It is difficult to be completely perpendicular to the sea level when deployed. The measurement data is not accurate enough. During measurement, false echoes caused by reverberation and false targets (such as fish, etc.) will have a great impact on the measurement results. Moreover, when working on the seabed, each module works at the same time, which requires relatively high battery requirements, large power consumption, and short service life, requiring frequent replacement of batteries.

为使发射声波和接收声波的换能器时间一致,减小测量误差,我们采取发射/接收二合一的水声换能器2。水声换能器2是通过水声信道发送和接收信号,采用90°开角向海面发射信号,根据不同水深设置发射功率,借助返回的声波信号获取声传播时间。水声换能器2包括信号产生电路、振荡器、声波发射器、声波接收器、转换器和智能处理器。水声换能器2的中心频率12kHz,工作水深500-5600米,具有圆锥状波束,开角90°,频带宽度150Hz。水声换能器2为圆柱状纵振换能器,最大声源级195dB,外壳采用硫化橡胶套,且硫化橡胶套外侧设有保护笼架,防止投放过程中损坏水声换能器2。In order to make the time of the transducers that emit sound waves and receive sound waves consistent and reduce measurement errors, we adopt a two-in-one underwater acoustic transducer 2 that emits/receives. The underwater acoustic transducer 2 sends and receives signals through the underwater acoustic channel, transmits signals to the sea surface with an opening angle of 90°, sets the transmission power according to different water depths, and obtains the sound propagation time by means of the returned acoustic wave signal. The underwater acoustic transducer 2 includes a signal generating circuit, an oscillator, a sound wave transmitter, a sound wave receiver, a converter and an intelligent processor. The center frequency of the underwater acoustic transducer 2 is 12 kHz, the working water depth is 500-5600 meters, it has a conical beam, the opening angle is 90°, and the frequency bandwidth is 150 Hz. The underwater acoustic transducer 2 is a cylindrical longitudinal vibration transducer with a maximum sound source level of 195dB.

The measurement interval parameters are saved in the duty module, and the transmission power adjustment and measurement depth range are saved in the main control module.
如图3所示,电子系统由值班模块进行长时间低功耗值班,其余电路模块处于断电状态,值班模块对外部实时时钟进行判别,符合测量时间点,则打开电子系统完成规定的测量任务,测量任务完成后关闭电子系统,保留值班模块的供电,等待下一次测量。As shown in Figure 3, the electronic system is on duty for a long time with low power consumption by the duty module, and the other circuit modules are in a power-off state. The duty module judges the external real-time clock, and if it meets the measurement time point, it turns on the electronic system to complete the specified measurement task After the measurement task is completed, the electronic system is turned off, and the power supply of the on-duty module is reserved, waiting for the next measurement.
电子系统开机进行测量时,主控模块控制回声测量模块工作,同时读取外部可选的传感器数据,回声测量模块工作完成后将测量数据传送给主控模块的数据接口,主控模块将测量数据和传感器数据按照MS-DOS的文件格式存储到CF存储卡中,测量结束,通知值班模块关机。When the electronic system is turned on for measurement, the main control module controls the echo measurement module to work, and at the same time reads the external optional sensor data. After the echo measurement module completes its work, it transmits the measurement data to the data interface of the main control module. And the sensor data are stored in the CF memory card according to the MS-DOS file format, and the measurement is completed, and the duty module is notified to shut down.
回收时启动释放器8释放掉锚系7,并依靠玻璃球4的浮力使设备上浮到海面。GPS信标机9利用一个小浮体3安装在系留系统的顶部,在设备上浮到海面时启动,向外发射GPS位置信息,回收船利用GPS信标机接收设备寻找该测量系统并进行回收。Start the release device 8 to release the mooring system 7 during recovery, and rely on the buoyancy of the glass ball 4 to make the equipment float to the sea surface. The GPS beacon machine 9 utilizes a small buoyant body 3 to be installed on the top of the mooring system, starts when the equipment floats to the sea surface, and transmits GPS position information outwards, and the recovery ship utilizes the GPS beacon machine receiving equipment to find the measurement system and reclaim it.
回声测量系统返回岸上以后,保存的数据可以有2种方式读入PC机。一种是将CF存储卡插入PC机的读卡器直接读取数据;另一种方式是选配无传模块,可以在不打开设备外壳的情况下通过无线串行接口直接读入PC机。After the echo measurement system returns to the shore, the saved data can be read into the PC in two ways. One is to insert the CF memory card into the card reader of the PC to read the data directly; the other is to choose a wireless module, which can directly read the data into the PC through the wireless serial interface without opening the device casing.
