Embodiment Construction
[0040] The present invention will be further explained below in conjunction with the drawings. Such as image 3 As shown, an ultrasonic side-scan ship draught detection system includes an ultrasonic transmitting array 1, an ultrasonic receiving array 2, a vertical ranging module 3, a draught detection processing unit 6 and a display alarm module 7. The ultrasonic receiving array 2. The vertical distance measuring module 3 and the display alarm module 7 are respectively connected to the draft detection processing unit 6 through wired transmission.
[0041] The ultrasonic transmitter array 1 is composed of n ultrasonic transmitter sensors installed in a row, and the ultrasonic receiver array 2 is composed of n ultrasonic receiver sensors installed in a row, and the n is greater than 2. The number and horizontal positions of the ultrasonic receiving sensors correspond to the number and horizontal positions of the ultrasonic transmitting sensors in the ultrasonic transmitting array 1...

The invention discloses an ultrasonic side scanning type ship draft detection system and method. The system comprises an ultrasonic transmitting array, an ultrasonic receiving array, a vertical ranging module, a draft detecting and processing unit and an alarm display module. The ultrasonic receiving array, the vertical ranging module and the alarm display module are connected with the draft detecting and processing unit in a wired transmission mode. According to the system, the ultrasonic transmitting array can adapt to changes of water levels and draft requirements, installation is convenient, and miniaturization of the draft detection system is realized; ultrasonic transmitting sensors in the ultrasonic transmitting array conduct ultrasonic transmission in a time-sharing mode, so interference between the ultrasonic transmitting sensors is eliminated, the ultrasonic receiving array can receive ultrasonic signals accurately, and the accuracy of measurement is improved; meanwhile, due to multiplexing of the ultrasonic receiving array, the complexity of the system is lowered. By the adoption of the system, a hardware system is omitted, and meanwhile the cost of the system is further lowered.
Description
Technical field [0001] The invention relates to a detection system and method for ship draft, in particular to an ultrasonic side scan type ship draft detection system and detection method. Background technique [0002] At present, the volume of inland waterway shipping is increasing year by year, the deadweight of ships is also increasing, and the draught of ships is getting deeper and deeper, leading to frequent shipping accidents. In order to ensure the safety of the waterway and navigation efficiency, the ship's draft must be measured. The existing ship draught detection methods mainly include: [0003] 1. Image recognition method; [0004] 2. Multi-beam ultrasonic measurement method; [0005] 3. Side sonar measurement method; [0006] 4. Single beam array method. [0007] Among the above methods, method 1 mainly relies on the accuracy of the ship’s own water gauge; method 2 because the price of the multi-beam ultrasonic sensor is higher, so the cost of the detection system is hig...
