Description

화물의 중량 및 체적 계측 시스템Cargo weight and volume measurement system
본 발명은 화물의 중량 및 체적 계측 시스템에 관한 것으로, 더욱 상세하게는 선박 또는 항공기에 적재 예정인 화물의 중량 및 체적 계측을 논스톱으로 진행할 수 있는 화물의 중량 및 체적 계측 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo weight and volume measurement system, and more particularly, to a cargo weight and volume measurement system capable of non-stop the weight and volume measurement of a cargo to be loaded on a ship or an aircraft.
선박 또는 항공기는 적재 가능 중량이상의 화물이 적재되거나, 어느 한쪽으로 하중이 편중되도록 화물이 적재되는 경우, 침몰 또는 추락의 위험에 노출되게 된다. 즉, 선박 또는 항공기에 적재될 화물의 중량 및 체적을 계측하는 것은 선박 또는 항공기의 안전과 화물의 보호를 위해 중요한 작업이다.A vessel or aircraft is exposed to the risk of sinking or falling if the cargo is loaded in such a way that the cargo is loaded above the loadable weight or the load is concentrated on either side. In other words, measuring the weight and volume of a cargo to be loaded on a vessel or aircraft is an important task for the safety of a vessel or aircraft and for the protection of cargo.

도 1에 도시되어 있는 바와 같이 종래의 측정 시스템은 정지된 화물의 외주면 전체를 연속적으로 스캔하여, 화물의 체적을 계측한다. 그러나 종래의 측정 시스템은 정지된 화물의 외주면 전체를 연속적으로 스캔하여야 하기 때문에, 체적의 계측에 많은 시간이 소요되어, 화물의 선적이 지연되는 문제점이 있었다.As shown in FIG. 1, the conventional measurement system continuously scans the entire outer circumferential surface of the stopped cargo to measure the volume of the cargo. However, since the conventional measurement system must continuously scan the entire outer circumferential surface of the stopped cargo, it takes a long time to measure the volume, and there is a problem that the shipment of the cargo is delayed.
따라서, 이동되는 화물에 대한 체적 계측을 실시하며 체적 계측에 많은 시간이 소요되지 않으면서 정확도가 높은, 화물의 중량 및 체적 계측 시스템에 대한 요구가 생기게 되었다.Therefore, there has been a demand for a cargo weight and volume measurement system, which carries out volumetric measurement of the cargo being moved and does not require much time for volumetric measurement, and has high accuracy.

As a result, the user does not need to separately calculate the total amount of cargo shipped to the ship or aircraft.

이와 같이 본 발명은 기설정된 간격으로 화물의 일부분에 대해 측정을 진행한 후, 이를 바탕으로 3차원 이미지를 생성하여 계측을 진행하기 때문에, 화물 전체를 촬영하는 종래의 방식에 비해 소비 전력을 줄이면서도, 계측의 정확성이 향상될 수 있다.As described above, according to the present invention, a measurement is performed on a part of a cargo at a predetermined interval, and then a three-dimensional image is generated based on the measurement, so that power consumption is reduced compared to a conventional method of photographing a whole cargo , The accuracy of the measurement can be improved.
도 6은 본 발명의 일 실시예에 따른 화물의 중량 및 체적 계측 방법을 도시하는 도면이다.6 is a view showing a method of measuring the weight and volume of a cargo according to an embodiment of the present invention.
S100단계에서 제어부(42)는 중량측정모듈(10)로부터의 중량데이터를 수신하고, S110단계에서 중량데이터가 기설정된 중량 이상인지 판단한다. 이때, 기설정된 중량은 화물의 최소 무게일 수 있다.In step S100, the control unit 42 receives the weight data from the weight measurement module 10, and determines whether the weight data is equal to or greater than a predetermined weight in step S110. At this time, the predetermined weight may be the minimum weight of the cargo.
중량데이터가 기설정된 중량 이상인 경우, S120단계에서 제어부(42)는 제2거리센서부(31)에 활성화 명령을 송신하여, 제2거리센서부(31)를 활성화한다. 이때, 제2거리센서부(31)는 일정한 유효시간 동안 활성화될 수 있으며, 유효시간 동안 제2거리데이터를 출력할 수 있다. If the weight data is equal to or greater than the predetermined weight, the control unit 42 transmits an activation command to the second distance sensor unit 31 in step S120 to activate the second distance sensor unit 31. [ At this time, the second distance sensor unit 31 can be activated for a certain valid time, and can output the second distance data for a valid time.
이후, S130단계에서 제어부(42)는 제2거리센서부(31)로부터 송신된 제2거리데이터가 기설정된 제1거리인지 판단하고, 기설정된 제1거리인 것으로 판단하면, S140단계에서 제1거리센서부(21)에 활성화 명령을 송신하여, 제1거리센서부(21)를 활성화하고, 제1거리센서부(21)로부터 제1거리데이터를 수신할 수 있다. 이때, 제1거리센서부(21)는 활성화 명령을 수신하는 순간에만 활성화되어, 제1거리데이터를 출력한다. 즉, 제1거리센서부(21)는 제2거리센서부(31)보다 짧은 유효시간 동안 활성화될 수 있다.Thereafter, in step S130, the control unit 42 determines whether the second distance data transmitted from the second distance sensor unit 31 is a predetermined first distance, and if it is determined that the second distance data is a predetermined first distance, It is possible to transmit the activation command to the distance sensor unit 21 to activate the first distance sensor unit 21 and receive the first distance data from the first distance sensor unit 21. [ At this time, the first distance sensor unit 21 is activated only at the moment of receiving the activation command, and outputs the first distance data. That is, the first distance sensor unit 21 can be activated for a shorter effective time than the second distance sensor unit 31.
S150단계에서 제어부(42)는 기설정된 제1거리와 제2거리데이터의 차가 기설정된 양의 정수(X)의 배수(n)인지 판단할 수 있다. 즉, 제어부(42)는 제2거리데이터가 소정의 간격(X)만큼 변하였는지 판단할 수 있다.In step S150, the controller 42 may determine whether the difference between the first distance data and the second distance data is a multiple (n) of a predetermined positive integer (X). That is, the control unit 42 can determine whether the second distance data has changed by the predetermined interval X. [
제1거리와 제2거리데이터의 차가 기설정된 양의 정수인 경우, S160 단계에서 제어부(42)는 제1거리센서부(21)에 활성화 명령을 송신하여 제1거리센서부(21)를 활성화하고, 제1거리센서부(21)로부터 제1거리데이터를 수신할 수 있다. If the difference between the first distance and the second distance data is a predetermined positive integer, the control unit 42 transmits an activation command to the first distance sensor unit 21 in step S160 to activate the first distance sensor unit 21 , And can receive the first distance data from the first distance sensor unit (21).
이후, S170단계에서 제어부(42)는 제1거리센서부(21)로부터 송신된 제1거리데이터가 기설정된 제2거리인지 판단할 수 있다. 이때, 제2거리는 제1거리센서부(21) 사이에 어떠한 화물도 위치하지 않았을 경우의 거리일 수 있다. 즉, 제어부(42)는 제1거리센서부(21) 사이에 화물이 위치하는지를 판단할 수 있다.Thereafter, in step S170, the controller 42 may determine whether the first distance data transmitted from the first distance sensor 21 is a predetermined second distance. In this case, the second distance may be a distance when no cargo is located between the first distance sensor units 21. That is, the control unit 42 can determine whether the cargo is located between the first distance sensor units 21.
제1거리데이터가 기설정된 제2거리가 아닌 것으로 판단하면, 제어부(42)는 제1거리센서부(21)를 활성화하는 S150단계로 돌아갈 수 있다.If it is determined that the first distance data is not the predetermined second distance, the control unit 42 may return to step S150 in which the first distance sensor unit 21 is activated.
제1거리데이터가 기설정된 제2거리인 것으로 판단하면, S180단계에서 제어부(42)는 제1거리데이터 및 제2거리데이터를 서로 대응되는 데이터끼리 묶어 복수의 데이터그룹을 생성하고 이를 형상생성부(43)로 송신해 3차원 이미지를 생성한다. S190단계에서 제어부(42)는 형상생성부(43)에서 송신된 3차원 이미지를 바탕으로 체적을 연산할 수 있다.If it is determined that the first distance data is a predetermined second distance, the controller 42 generates a plurality of data groups by grouping the first distance data and the second distance data into corresponding data, (43) to generate a three-dimensional image. In step S190, the control unit 42 can calculate the volume based on the three-dimensional image transmitted from the shape generation unit 43.
이와 같이 본 발명은 화물의 중량에 의해 제2거리센서부(31)가 자동으로 활성화될 수 있으며, 제2거리센서부(31)에 측정된 거리에 따라 제1거리센서부(21) 및 제3거리센서부(22)가 자동으로 활성화되어 화물의 특정 단면에 대한 측정을 실시하고 이를 바탕으로 체적을 연산할 수 있다. 즉, 본 발명은 최소한으로 제1거리센서부(21) 내지 제3거리센서부(22)를 활성화하기 때문에, 화물의 체적을 계측하는데 많은 전력이 소모되지 않으면서, 많은 시간이 소요되지 않는다 As described above, according to the present invention, the second distance sensor unit 31 can be automatically activated by the weight of the cargo, and the first distance sensor unit 21 and the second distance sensor unit 31 can be automatically activated according to the measured distance to the second distance sensor unit 31 3 distance sensor unit 22 is automatically activated to measure the specific cross-section of the cargo and calculate the volume based on this. That is, since the present invention activates the first distance sensor unit 21 to the third distance sensor unit 22 at a minimum, much power is not consumed in measuring the volume of the cargo,

중량 측정이 완료되면, S220단계에서 화물은 중량측정모듈(10)에서 진출하게 되고, S230단계에서 넓이측정모듈(20)에 진입하게 된다. 이때, S310단계에서 시스템(1)의 제2거리센서부(31)는 계속해서 거리를 측정하여 컨트롤박스(40)로 송신하고, 컨트롤박스(40)는 제2거리센서부(31)의 측정값에 따라, 넓이측정모듈(20)의 제1거리센서부(21) 및 제3거리센서부(22)를 활성화하여, 체적 측정을 시작할 수 있다. 이때, 제1거리센서부(21) 및 제3거리센서부(22)는 화물의 너비 및 높이에 대한 측정을 진행하고, 제1거리데이터 및 제3거리데이터를 생성하여 컨트롤박스(40)로 송신할 수 있다. When the weight measurement is completed, the cargo advances in the weight measurement module 10 in step S220, and enters the area measurement module 20 in step S230. At this time, in step S310, the second distance sensor unit 31 of the system 1 continuously measures the distance and transmits it to the control box 40. The control box 40 measures the distance of the second distance sensor unit 31 The first distance sensor portion 21 and the third distance sensor portion 22 of the width measurement module 20 can be activated to start the volume measurement. At this time, the first distance sensor unit 21 and the third distance sensor unit 22 measure the width and the height of the cargo, generate the first distance data and the third distance data, and transmit them to the control box 40 Can be transmitted.
S240단계에서 화물은 넓이측정모듈(20)에서 진출하고, 화물이 넓이측정모듈(20)에서 진출하게 되면, S320단계에서 시스템(1)의 컨트롤박스(40)는 화물의 중량 및 체적 측정을 종료하고, S330단계에서 화물의 중량 및 체적을 연산한다.In step S240, the cargo advances in the area measurement module 20. When the cargo advances in the area measurement module 20, the control box 40 of the system 1 in step S320 ends the weight and volume measurement of the cargo And calculates the weight and volume of the cargo in step S330.
본 발명의 일 실시예에 따르면, 본 발명은 화물의 이동에 따라 중량 및 체적 계측을 실시할 수 있으며, 화물의 이동 정도에 따라 화물의 체적 계측을 위한 거리센서부(21, 22, 31)가 활성화되기 때문에, 불필요한 전력소모를 방지할 수 있다.According to an embodiment of the present invention, weight and volume measurement can be performed according to the movement of a cargo. Distance sensors 21, 22, 31 for measuring the volume of cargo are provided according to the degree of movement of the cargo So that unnecessary power consumption can be prevented.
또한, 본 발명은 화물 전체를 연속적으로 스캔하지 않고, 특정 단면에 대해서만 스캔을 진행하여 체적을 연산하기 때문에, 체적 계측에 시간이 소요되지 않을 수 있다.Further, since the present invention does not continuously scan the entire cargo but scans only a specific cross section to calculate the volume, it may take time to measure the volume.
