Description

건설기계의 잔여 작업 시간 예측 방법How to predict remaining working time of construction machinery

본 공개는 연료 탱크의 연료 잔량을 기준으로, 엔진 모드 별로 최대 작업 가능시간에 대한 정보를 운전자에게 알려줄 수 있는 것을 특징으로 하는 건설기계에 관한 것이다.The present disclosure relates to a construction machine, characterized in that it is possible to inform the driver of the maximum working time for each engine mode, based on the remaining fuel in the fuel tank.

자동차의 경우, 연료탱크에 남은 연료의 양을 기준으로 최대 주행할 수 있는 거리를 산정, 이를 차량의 계기판에 표시해 주므로서, 차량의 운전자가 적절한 시점에 연료를 보충할 수 있도록 하는데 도움을 주고 있다. 건설장비에도 연료 잔량에 따라 작동가능한 시간을 보여주는 기능이 적용되고 있으나, 건설장비 중 굴삭기를 예로 들어보면, 종래 기술은 현재 운전 중인 굴삭기의 모드와 상관없이 작동 가능한 작업 시간을 획일적으로 보여주는 것에 그치고 있다. 건설장비에는 다양한 작업 모드가 존재할 수 있으며, 선택된 작업 모드에 따라 연료 소비율이 달라질 수 있으므로 선택된 작업 모드에 따라 개별화된 작동 가능한 작업 시간을 보여줄 필요가 있다. In the case of automobiles, the maximum distance that can be driven based on the amount of fuel remaining in the fuel tank is calculated and displayed on the dashboard of the vehicle, thereby helping the driver of the vehicle to replenish the fuel at an appropriate time. . In the construction equipment, the function of showing the operating time according to the fuel level is applied, but in the case of the excavator in the construction equipment, the prior art is only showing a uniform working time irrespective of the mode of the excavator currently in operation. . There may be a variety of working modes in construction equipment, and the fuel consumption rate may vary according to the selected working mode, so it is necessary to show the individual working hours according to the selected working mode.

본 공개에 따른 건설기계의 잔여 작업 시간 예측 방법은, 연료 탱크의 연료 잔량을 기준으로, 엔진의 회전수를 선택할 수 있도록 제공되는 모드 별로 최대 작업 가능시간에 대한 정보를 운전자에게 알려줌으로서, 장비 운전자가 연료 주입이 필요한 시점을 좀 더 명확히 인식해, 예기치 않은 연료 부족, 연료 보충 작업으로 진행중인 작업이 지연되는 문제가 발생하는 것을 예방하게 하는데 도움을 주고자하는 목적을 가지고 있다.The method of estimating the remaining working time of a construction machine according to the present disclosure provides the driver with information on the maximum working time for each mode provided to select an engine speed based on the fuel remaining amount of the fuel tank. The aim is to help to more clearly recognize when fuel injection is needed, and to help prevent unexpected fuel shortages and delays in ongoing fuel replenishment.

본 공개에 따른 건설기계는 잔여 작업 시간을 예측하기 위해 엔진, 연료탱크의 연료량을 측정할 수 있는 연료레벨센서, 상기 엔진의 회전수를 선택할 수 있는 작업모드 스위치, 상기 연료레벨센서로부터 연료 정보를 수신하고, 상기 엔진으로부터 연비 정보를 입력받아, 선택된 작업모드에 따라 예상 작업 시간을 산출할 수 있는 제어부를 포함한다.The construction machine according to the present disclosure provides fuel information from an engine, a fuel level sensor capable of measuring a fuel level of a fuel tank, a work mode switch capable of selecting a rotational speed of the engine, and fuel information from the fuel level sensor to predict a remaining working time. And a controller configured to receive the fuel efficiency information from the engine and calculate an expected working time according to the selected working mode.

본 발명을 통해, 운전자는 장비에 남아 있는 연료량을 기준으로 최대 작업 가능한 작업시간을 인지하게 됨에 따라, 향후 남은 작업 시간 등을 고려, 연료 주입 시점을 적절히 결정할 수 있을 것으로 기대된다. 아울러, (엔진의 회전수를 선택할 수 있도록 제공되는) 모드별 최대 작업 가능시간을 표시해 주므로써, 연료 부족으로 인해 장비가 운행 정지되는 상황을 예방하기 위해서는 어떤 모드로 운전자가 장비를 운전해야하는지 판단을 하는데 도움을 줄 수 있을 것으로 예상되며, 궁극적으로는 건설기계의 생산성 향상에 기여할 것으로 기대된다.According to the present invention, the driver is expected to be able to determine the fuel injection time appropriately in consideration of the remaining work time in the future, as the operator knows the maximum working time based on the amount of fuel remaining in the equipment. In addition, by displaying the maximum working time for each mode (provided to select the engine speed), it is possible to determine in which mode the driver should operate the machine in order to prevent the machine from shutting down due to lack of fuel. It is expected to help improve the productivity of construction machinery.

이하, 첨부된 도면을 참조하여 본 발명을 설명한다.Hereinafter, with reference to the accompanying drawings will be described the present invention.

다만, 이하에서 설명되는 실시예는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 발명을 쉽게 실시할 수 있을 정도로 상세하게 설명하기 위한 것에 불과하며, 이로 인해 본 발명의 보호범위가 한정되는 것을 의미하지는 않는다.However, the embodiments described below are merely to describe in detail enough to be able to easily carry out the invention by those skilled in the art to which the present invention pertains, thereby limiting the protection scope of the present invention It does not mean.

본 발명을 명확하게 설명하기 위해서 설명과 관계없는 부분은 생략하였으며 명세서 전체를 통하여 유사한 부분에 대해서는 유사한 도면 부호를 붙였다.In order to clearly describe the present invention, parts irrelevant to the description are omitted and like reference numerals denote like parts throughout the specification.

건설기계, 그 중에서도 특히 굴삭기의 경우, 작업 모드 스위치에 의해 결정된 모드에 따라, 엔진의 회전수가 선택(조정)될 수 있으며, 장비에서 사용할 수 있는 파워가 달라지는 특징을 가지고 있다. 그러므로, 연료탱크에 남은 연료의 양을 기준으로 계산된 장비 최대 가동 시간도 (엔진) 모드에 따라 달라질 수 밖에 없는 특징을 가지고 있다.In the case of construction machinery, especially excavators, the engine speed can be selected (adjusted) according to the mode determined by the work mode switch, and the power available to the equipment is changed. Therefore, the maximum equipment running time calculated based on the amount of fuel remaining in the fuel tank also has a characteristic that can vary depending on the (engine) mode.

이에 본 공개에 따른 잔여 작업 시간 예측 방법에서는, 모드를 장비 최대 가동시간을 계산하는 데 있어 하나의 중요한 입력으로 삼아, 엔진 가동시간에 따른 장비 최대 가동시간을 다르게 나타내는 것을 구현하고자 한다. Accordingly, in the method for estimating the remaining working time according to the present disclosure, the mode is used as one important input for calculating the maximum operating time of the equipment, and the implementation of representing the maximum operating time according to the engine operating time is different.

도 1은 본 공개의 일 실시예에 따른 건설기계의 블록도이다.1 is a block diagram of a construction machine according to an embodiment of the present disclosure.

본 공개의 일 실시예에 따른 건설기계는 엔진, 연료탱크(60)의 연료량을 측정할 수 있는 연료레벨센서(50), 상기 엔진의 회전수를 선택할 수 있는 작업모드 스위치(20), 상기 연료레벨센서로부터 연료 정보를 수신하고, 상기 엔진으로부터 연비 정보를 입력받아, 선택된 작업모드에 따라 예상 작업 시간을 산출할 수 있는 제어부(10)를 포함할 수 있다.Construction equipment according to an embodiment of the present disclosure is an engine, a fuel level sensor 50 that can measure the amount of fuel in the fuel tank 60, a work mode switch 20 for selecting the rotational speed of the engine, the fuel The control unit 10 may receive fuel information from a level sensor, receive fuel economy information from the engine, and calculate an expected work time according to a selected work mode.

도 2은 본 공개의 일 실시예에 따른 제1순서도이며 본 공개에 따른 건설기계가 어떻게 작업 모드에 따라 예상 작업 시간을 산출하는지 보여준다.2 is a first flowchart according to an embodiment of the present disclosure and shows how a construction machine according to the present disclosure calculates an expected working time according to a working mode.

먼저 건설기계의 제어부(10)는 작업모드 스위치(20)에 의해 모드를 입력받는다(S100). 만약 상기 작업모드 스위치(20)에 의해 입력받은 모드가 제1모드인 경우(S110), 상기 제어부는 제1모드에서의 평균 연비 - P_average_fuel(P_cnt, ave_P) - 를 산정하고(S120), 이를 제1모드에서의 평균 연비(Average fuel consumption = ave_P)로 설정한다.First, the control unit 10 of the construction machine receives the mode by the work mode switch 20 (S100). If the mode input by the work mode switch 20 is the first mode (S110), the controller calculates an average fuel economy -P_average_fuel (P_cnt, ave_P)-in the first mode (S120). Set to average fuel consumption (Average fuel consumption = ave_P) in 1 mode.

이후 상기 제어부는 S140 단계에서 제1모드에서의 연료 잔량을 고려하여 잔여 작업 시간(P_fore_T_new)을 계산한다. 여기서 잔여 작업 시간은 연료레벨 / 평균연비 (Fuel level / Average fuel consumption)의 관계로 설정된다.Thereafter, the controller calculates the remaining work time P_fore_T_new in consideration of the fuel remaining amount in the first mode in step S140. The remaining working time is set in relation to the fuel level / average fuel consumption.

이후 S150 단계로 진행하는데, 만약 제1모드에서 일정시간 동안 평균 연비를 계산한 것이 첫번째인 경우 (If P_cnt = 1), S160 단계에서 상기 제어부에 의해 계산된 잔여 작업 시간(제1 잔여 작업 시간)을 제1모드의 예상 작업 시간으로 설정하게 된다.Thereafter, the process proceeds to step S150. If the first calculation of the average fuel economy for a predetermined time in the first mode (If P_cnt = 1), the remaining work time (first remaining work time) calculated by the controller in step S160. Set to the expected working time of the first mode.

만약 만약 제1모드에서 일정시간 동안 평균 연비를 계산한 것이 첫번째가 아닌 경우 S300 단계로 진행하며, S300 단계에서 상기 제어부는 제1모드가 선택된 횟수가 2회 이상이고 모드의 변경이 없는지 여부를 판단한다. 만약 제1모드가 선택된 횟수가 2회 이상이고 모드의 변경이 없는 경우, 상기 제어부는 이전 잔여 작업 시간 계산 단계에서 계산된 제2 잔여 작업 시간과 현재 잔여 작업 시간 계산 단계에서 새로 계산된 제1 잔여 작업 시간을 비교하게 된다. 이는 순서도에서 If (Engine speed mode == espd_M_old && P_fore_T_new > P_fore_T_old) 로 표현된다.If it is not the first time that the average fuel economy is calculated for a predetermined time in the first mode, the process proceeds to step S300. In step S300, the controller determines whether the first mode is selected more than once and there is no change of mode. do. If the number of times that the first mode is selected is two or more times and there is no change in the mode, the controller controls the second remaining work time calculated in the previous remaining work time calculation step and the first remaining work calculated in the current remaining work time calculation step. The work time is compared. This is represented in the flowchart as If (Engine speed mode == espd_M_old && P_fore_T_new> P_fore_T_old).

현재 잔여 작업 시간 계산 단계에서 새로 계산된 제1 잔여 작업 시간이 이전 잔여 작업 시간 계산 단계에서 계산된 제2 잔여 작업 시간보다 크다면, S310 단계로 진행하여, 예상 작업 시간은 이전에 계산된 제1모드에서의 잔여 작업 시간과 동일하게 설정된다 (Forecasted time to work = P_fore_T_old).If the first remaining work time newly calculated in the current remaining work time calculation step is greater than the second remaining work time calculated in the previous remaining work time calculation step, the flow proceeds to step S310, and the estimated work time is the first calculated first time. It is set equal to the remaining work time in the mode (Forecasted time to work = P_fore_T_old).

다른 말로, 제1 잔여 작업 시간이 상기 제2 잔여 작업 시간보다 큰 경우, 상기 제어부는 이전 잔여 작업 시간 계산 단계에서 계산된 제2 잔여 작업 시간을 예상 작업 시간으로 설정하게 된다.In other words, when the first remaining working time is greater than the second remaining working time, the controller sets the second remaining working time calculated in the previous remaining working time calculation step as the expected working time.

도 3는 제1순서도에서 모드별 평균 연비를 계산하는 단계를 구체적으로 나타내는 제2순서도이다. 도 3은 평균 연비가 어떻게 산출되는지 더 자세히 보여준다.FIG. 3 is a second flowchart specifically illustrating a step of calculating an average fuel economy for each mode in the first flowchart. 3 shows in more detail how the average fuel economy is calculated.

S400 단계에서 If (P_cnt == 0) 이라고 기재되어 있는데, 여기서 P_cnt는 모드가 선택된 횟수를 나타내며, 즉 S400 단계는 제1모드가 선택된 횟수가 처음인 경우를 판별한다. 만약 제1모드가 선택된 횟수가 처음인 경우 S410 단계로 진행하고, 제1모드가 선택된 횟수가 처음이 아닌 경우 S420 단계로 진행한다.If (P_cnt == 0) is described in step S400, where P_cnt indicates the number of times the mode is selected, that is, the S400 step determines the first time the number of times the first mode is selected. If the number of times the first mode is selected is the first time, the process proceeds to step S410. If the number of times the first mode is selected is not the first time, the process proceeds to step S420.

S410 단계에서 평균 연비는 제1모드의 평균 연비의 초기 값으로 설정된다. 즉, 건설기계에 이미 설정되어 있던 평균 연비의 초기 값이 입력되는 것이며 제1모드가 선택된 횟수는 증가하게 된다(P_cnt ++)In operation S410, the average fuel economy is set to an initial value of the average fuel economy of the first mode. That is, the initial value of the average fuel efficiency already set in the construction machine is inputted, and the number of times the first mode is selected is increased (P_cnt ++).

위와 같은 단계를 거쳐 제1모드가 한번 이상 선택된 경우, S420 단계로 진행한다. S420 내지 S450 단계는 건설기계에 설정되는 모드에서 샘플링 횟수에 따라 평균 연비를 구하는 메커니즘을 도시한다. 즉 i는 순간 연비가 측정되는 횟수를 나타내며 샘플링 횟수(SAMPLING NO)는 평균 연비를 측정하기 위해 순간 연비가 측정되어야 하는 횟수를 나타낸다. 순간 연비가 측정될 때마다 순간 연비가 측정된 횟수 i는 1씩 증가하게 되며, 순간 연비 또한 계속 합산된다 (sum + = instant fuel consumption). 이렇게 반복적으로 순간 연비가 합산되며 측정되다가 i가 샘플링 횟수와 같아지는 경우 그 때까지의 순간연비 합산값 (sum)을 샘플링 횟수로 나누어 평균 연비를 계산하게 된다.If the first mode is selected more than once through the above steps, the process proceeds to step S420. Steps S420 to S450 show a mechanism for obtaining average fuel efficiency according to the number of sampling in the mode set in the construction machine. I represents the number of times the instantaneous fuel economy is measured and the number of sampling (SAMPLING NO) represents the number of times the instantaneous fuel economy should be measured in order to measure the average fuel economy. Each time instantaneous fuel economy is measured, the number of times instantaneous fuel economy is measured increases by 1, and the instantaneous fuel economy is also summed (sum + = instant fuel consumption). When the instantaneous fuel economy is added and measured repeatedly, and i is equal to the number of sampling, the average fuel economy is calculated by dividing the sum of the instantaneous fuel economy up until then by the number of sampling.

즉, 다시말해 만약 제1모드가 선정된 횟수가 2회 이상인 경우, 상기 제어부는 i = 0 으로 설정하고(S420), i가 샘플링 횟수(sampling number)와 같아질 때까지 i를 1씩 증가시키며 i가 1씩 증가할 때마다 순간 연비를 합한 값을 합산값(sum)으로 설정하고(S430, S440), i가 샘플링 횟수와 같아지는 경우 '제1모드의 평균 연비 = 상기 합산값(sum) / 샘플링 횟수(sampling number)' 로 설정하게 된다(S450).In other words, if the number of times the first mode is selected is two or more times, the controller sets i = 0 (S420) and increments i by 1 until i is equal to the sampling number. Whenever i increases by 1, the sum of instantaneous fuel economy is set as a sum (S430, S440), and when i is equal to the number of sampling, 'the average fuel economy of the first mode = the sum (sum) / Sampling number '(S450).

본 공개는 건설기계의 예상 작업 시간 계산을 계산하는 방법 또한 제공할 수 있다.The present disclosure may also provide a method for calculating the expected working time calculation of construction equipment.

According to the present disclosure, a method for measuring an expected working time of a construction machine according to the present disclosure may include: i) receiving a mode by a control unit by a mode switch; ii) when the received mode is a first mode, the control unit averages fuel economy in the first mode. Iii) calculating the remaining working time in consideration of the fuel remaining amount in the first mode, and iv) calculating the average fuel consumption for a predetermined time in the first mode.
