技术领域technical field

背景技术Background technique
目前,随着内河航运量不断增大,船舶密度大幅提高。船舶吃水检测对于保障通航船舶安全具有十分重要的意义。现有的船载侧吃水检测系统是构建单一线阵列的超声波发射模块,然后利用同步使能模块分时控制超声波发射传感器等间隔地依次循环发射超声波,再根据超声波传感器接收端接收的直达波推出船舶吃水深度。此方法适用于固定安装或满足发射换能器阵列摆角很小的情况,当摆角过大时,因接收线阵列无法正确接收发射线阵列相对应的信号,造成系统无法正常工作,因此该方法无法直接用于船载安装,使得其应用受到很大的限制。At present, with the increasing volume of inland waterway shipping, the density of ships has increased significantly. Ship draft detection is of great significance to ensure the safety of navigable ships. The existing shipboard side draft detection system is to build a single line array of ultrasonic transmitting modules, and then use the synchronous enabling module to control the ultrasonic transmitting sensors to transmit ultrasonic waves at equal intervals in sequence, and then push out according to the direct waves received by the receiving end of the ultrasonic sensors. The ship's draft. This method is suitable for fixed installation or when the swing angle of the transmitting transducer array is very small. When the swing angle is too large, the system cannot work normally because the receiving line array cannot correctly receive the signal corresponding to the transmitting line array. The method cannot be directly used for shipboard installation, so its application is greatly limited.

The angle of the probe of the line array deviates too much from the horizontal line, which leads to the fact that the ultrasonic transmitting probe is not in the reasonable working range, which further affects the problem that the receiving line array cannot correctly receive the signal corresponding to the transmitting line array.

安装在航道另一侧的超声波接收模块4接收信号并实时传给数据处理模块7。The ultrasonic receiving module 4 installed on the other side of the channel receives the signal and sends it to the data processing module 7 in real time.
步骤7:数据处理;Step 7: data processing;
数据处理模块7根据发射端压力传感器模块6传送的超声波发射线阵中心位置距离水面的深度H计算出第I个安装支架10上的超声波发射线阵第一个超声波发射探头9距离水面的深度H1以及接收端压力传感器模块5传送的超声波接收线阵中心位置距离水面的深度L计算出水下第一个超声波接收探头距离水面的深度L1,H1和L1取平均后的值D作为水下第一个超声波接收探头距离水面的深度,再结合超声波接收线阵接收的信号强弱计算出下端最后一个被遮挡超声波接收探头距离第一个超声波接收探头的长度X进而计算出吃水深度为D+X。The data processing module 7 calculates the depth H of the first ultrasonic emission line array on the I mounting bracket 10 from the first ultrasonic emission probe 9 of the ultrasonic emission line array to the water surface according to the depth H of the ultrasonic emission line center position transmitted by the transmitter pressure sensor module 6 from the water surface 1 and the depth L of the center position of the ultrasonic receiving linear array transmitted by the pressure sensor module 5 at the receiving end from the water surface to calculate the depth L 1 of the first underwater ultrasonic receiving probe from the water surface, and the average value D of H 1 and L 1 is used as the water surface The depth of the first ultrasonic receiving probe from the water surface, combined with the strength of the signal received by the ultrasonic receiving line array, calculates the length X of the last blocked ultrasonic receiving probe at the lower end from the first ultrasonic receiving probe, and then calculates the draft as D +X.
以下通过附图对互成角度的多发射线阵补偿浮体11上仰角度β带来的误差做进一步地描述:The error caused by the elevation angle β of the buoyant body 11 is further described by the mutually angled multi-emission linear array compensation in the following drawings:
如图2所示,当浮体上仰角度β,同步使能模块2对角度传感器模块1实时传送的浮体11上仰角度β进行处理,即计算:As shown in Figure 2, when the floating body is raised at an angle β, the synchronization enabling module 2 processes the raised angle β of the floating body 11 transmitted by the angle sensor module 1 in real time, that is, calculates:
i=-INT(β/θ+0.5),INT表示取整数,则选取第i个安装支架10上的超声波发射线阵作为发射线阵,如果β值远远小于θ值,则选取编号为0安装支架10上的超声波发射线阵作为发射线阵。i=-INT(β/θ+0.5), INT means taking an integer, then select the ultrasonic emission line array on the i-th installation bracket 10 as the emission line array, if the β value is far less than the θ value, then select the number as 0 The ultrasonic emission line array on the mounting bracket 10 is used as the emission line array.
