전동지게차 등의 배터리 원격 모니터링 시스템 {REMOTE MONITORING SYSTEM FOR BATTERY OF ELECTRIC FORKLIFT TRUCK AND THE LIKE}Battery remote monitoring system for electric forklifts, etc. {REMOTE MONITORING SYSTEM FOR BATTERY OF ELECTRIC FORKLIFT TRUCK AND THE LIKE}

본 발명은 전동지게차 등의 배터리 원격 모니터링 시스템에 관한 것으로서, 전동지체차의 배터리, 의약품 냉동고의 배터리, 통신설비의 배터리, 소형자동차용 배터리 등 각 장소에 산재되어 사용되는 배터리에 대하여 충전상태, 발열상태, 충전횟수 등을 원격지에서 모니터링함으로써, 배터리의 점검, 교체, 수리업무를 효율적으로 수행할 수 있도록 하는 배터리 원격 모니터링 시스템에 관한 것이다.The present invention relates to a battery remote monitoring system for an electric forklift, etc., and relates to a battery of an electric delayed vehicle, a battery of a medicine freezer, a battery of a communication facility, a battery for a small car, etc. It relates to a battery remote monitoring system capable of efficiently performing battery inspection, replacement, and repair tasks by remotely monitoring the state, the number of times of charging, and the like.

종래 산업용 배터리는 비상 전원용으로 제한적으로 사용되어 왔으나, 최근에 환경적, 경제적 요인 또는 편의성에 의해 전동지게차, 소형자동차 등에 탑재하여 구동전원으로 사용되고 있다.Conventional industrial batteries have been limitedly used for emergency power, but recently, due to environmental and economic factors or convenience, they are mounted on electric forklifts and small cars and used as driving power.

전동지게차의 경우, 납축전지를 사용하고 있으며, 사용 개시 후 2~3년이 지나면 사용 지속시간이 절반 이하로 줄어들게 되어 결국 폐기가 필요하다.In the case of electric forklifts, lead-acid batteries are used, and after two to three years after the start of use, the duration of use is reduced to less than half, and eventually they need to be disposed of.

또한, 그러한 전동지게차의 배터리는 안정적인 전압출력을 유지하는 장점이 있으나, 과충전 및 과방전시 배터리 수명이 급격히 단축되며, 과방전 상태가 지속될 경우 배터리 수명에 치명적인 요인으로 작용한다.In addition, the battery of such an electric forklift has the advantage of maintaining a stable voltage output, but the battery life is rapidly shortened during overcharge and overdischarge, and when the overdischarge state continues, it acts as a fatal factor to the battery life.

또한, 납축전지로 이루어진 배터리는 증류수를 너무 자주 보충하면, 충전 중, 셀간 비중이 달라져 셀간 출력이 달라지고 어느 하나의 셀에 부하가 과중되어 배터리 수명을 단축시키는 원인이 된다.In addition, if distilled water is replenished too frequently in a battery made of a lead-acid battery, the specific gravity between cells varies during charging, so that the output between cells is changed, and the load on any one cell is excessive, thereby shortening the battery life.

이에, 배터리의 수명 연장 및 배터리 관련 사고를 방지할 수 있도록, 종래 배터리의 전압 및 전류를 측정해서 배터리의 상태를 유추하거나, 관리자가 배터리의 상태를 직접 모니터링 하여 그 결과에 따라 경험적인 관리를 진행하고 있었다.Accordingly, in order to extend the life of the battery and prevent battery-related accidents, the state of the battery is inferred by measuring the voltage and current of the conventional battery, or the manager directly monitors the state of the battery and conducts empirical management according to the result. was doing

또한, 배터리에 블루투스 등과 같은 근거리 통신용 모듈이 장착된 경우라도, 관리자가 각 전동지게차 주변으로 이동해서 배터리의 정보를 수신하고, 육안으로 재점검하는 방식이 흔히 이용되고 있었다.Also, even when a short-distance communication module such as Bluetooth is installed in the battery, a method in which an administrator moves around each electric forklift to receive battery information and visually re-inspect has been commonly used.

결국, 관리자가 해당 사업장의 배터리를 일일이 확인하는 방식에 의한 유지관리가 진행되고 있어, 관리하는 배터리의 수가 늘어나는 경우, 효율적인 관리가 이루어질 수 없고, 배터리의 비효율적 사용으로 비용과 시간의 낭비도 늘어난다.As a result, maintenance is carried out in a way that the manager checks the batteries of the relevant business site one by one, and if the number of batteries to be managed increases, efficient management cannot be achieved, and the inefficient use of batteries also increases the waste of money and time.

이에, 산업용 배터리의 수요가 크게 증가하는 현실에 맞게, 이들을 체계적으로 관리하여 점검, 보수, 교체하기 위한 효율적 시스템에 대한 필요성이 높다.Accordingly, there is a high need for an efficient system for systematically managing, inspecting, repairing, and replacing industrial batteries in accordance with the reality in which the demand for industrial batteries is greatly increased.

또한, 각 사업장에서 사용하는 다수의 배터리가 순차적으로 노후화됨에 의해 노후화된 배터리를 새로운 배터리로 교체하는 시기가 순차적으로 도래함에 따라, 수많은 사업장을 관리하는 관리업체의 입장에서 소수의 배터리 교체작업을 위해 빈번히 여러 작업장을 방문해야 하고, 해당 사업장에서도 소수의 배터리 교체, 점검을 위해 관리업체의 직원이 빈번히 방문함으로써 업무효율을 저해하는 요인이 되고 있다.In addition, as the number of batteries used in each business site deteriorates sequentially, the time to replace the old batteries with new batteries sequentially arrives. Frequent visits to multiple workplaces are required, and employees from management companies frequently visit the workplace to replace and inspect a small number of batteries, which is a factor impeding work efficiency.

상기 배터리(20)는 전동지게차 등에 사용되고 전해액을 수용한 납축전지가 될 수 있고, 납축전지는 안정적인 전압 출력을 유지하는 장점이 있으나, 과충전 및 과방전시 배터리(20) 수명이 급격히 단축된다. The battery 20 may be a lead-acid battery used for an electric forklift, etc. and containing an electrolyte, and the lead-acid battery has the advantage of maintaining a stable voltage output, but the life of the battery 20 is rapidly shortened during overcharging and overdischarging.

전술한 시스템의 구성에 의해, 각 사업장의 관리자가 관리서버(70)로부터 배터리(20)의 상태정보 즉, 온도정보, 전해액 레벨정보, 배터리(20) 충전회수 등에 관한 정보를 전달받을 수 있어, 각 배터리(20)를 일일이 육안으로 점검할 필요없이, 배터리(20)의 효율적 사용 및 수명연장을 위한 관리를 용이하게 수행할 수 있다.By the configuration of the system described above, the manager of each business site can receive information about the state information of the battery 20, that is, temperature information, electrolyte level information, the number of times of charging the battery 20, from the management server 70, Without the need to visually inspect each battery 20 , it is possible to easily perform management for efficient use and life extension of the battery 20 .

또한, 각 사업장의 관리자와 관리서버(70)를 운영하는 배터리(20) 관리업체 간에 배터리(20)의 상태정보를 공유하므로, 각 사업장과 배터리(20) 관리업체 사이의 배터리(20) 관리업무 상의 문제소지를 없애고, 객관적이고 신뢰성있는 유지관리 업무의 진행이 가능하게 된다.In addition, since the state information of the battery 20 is shared between the manager of each business site and the battery 20 management company that operates the management server 70, the battery 20 management task between each business site and the battery 20 management company It eliminates potential problems and enables objective and reliable maintenance work.

특히, 관리서버(70)는 충전횟수카운터(36)에 의한 배터리(20) 충전 횟수를, 배터리(20)의 전체 사용기간(신품장착 후 교체까지의 기간)동안 전송받아 각 사업장의 관리자단말기(80)로 전달할 수 있는 바, 각 사업장의 관리자는 배터리(20)의 현재까지 충전 횟수를 파악할 수 있어 배터리(20)의 수명에 대한 예측이 가능하고, 배터리(20)의 품질에 관해 관리업체와의 분쟁도 예방할 수 있다.In particular, the management server 70 receives the number of times the battery 20 is charged by the charge counter 36 during the entire usage period of the battery 20 (period from installation of new product to replacement), and receives it from the manager terminal ( 80), the manager of each business site can grasp the number of times the battery 20 has been charged so far, so that the lifespan of the battery 20 can be predicted, and the quality of the battery 20 can be communicated with the management company. conflicts can also be prevented.

한편, 본 실시예의 배터리 원격 모니터링 시스템은, 단일 사업장에서 사용되는 복수의 배터리(20)의 노후화를 균일하게 유도하고 교체시기를 대략적으로 일치시키 수 있도록 관리한다.On the other hand, the battery remote monitoring system of this embodiment manages to uniformly induce the aging of the plurality of batteries 20 used in a single workplace and to roughly match the replacement timing.

즉, 관리서버(70)는 단일 사업장에 운용되는 복수의 구동장치(10a,10b,10c;10)에 설치된 각 배터리(20)에 대하여, 배터리(20)의 상태정보에 의해 각 배터리(20)의 노후화 정도를 산출하여 단일 사업장에서 각 배터리(20)의 노후화 순위를 결정하고, 결정된 순위에 따라 평균보다 노후화 정도가 높은 배터리(20)와 평균보다 노후화 정도가 낮은 배터리(20)를 서로 일대일로 매칭시킨 배터리교환정보를 생성하며, 그 배터리교환정보를 사업장의 관리자단말기(80)에게 전송한다.That is, the management server 70 for each battery 20 installed in a plurality of driving devices 10a, 10b, 10c; 10 operated in a single business site, each battery 20 by the state information of the battery 20 The aging degree of each battery 20 is determined in a single workplace by calculating the degree of aging of The matched battery exchange information is generated, and the battery exchange information is transmitted to the manager terminal 80 of the business place.

단일 사업장에서 사용되는 복수의 구동장치(10a,10b,10c;10)는 각 구동장치(10)의 성능 또는 노후화 정도, 작업자의 운전습관, 각 구동장치(10)가 수행하는 작업종류에 따라, 그 각각에 장착된 배터리(20)의 소모량, 충전횟수에 큰 차이가 발생하므로, 노후화 정도에 각기 차이가 발생하는 것이다.A plurality of driving devices 10a, 10b, 10c; 10 used in a single workplace depends on the performance or degree of deterioration of each driving device 10, the driving habits of the operator, and the type of work performed by each driving device 10, Since there is a big difference in the consumption amount and the number of times of charging of the battery 20 mounted thereon, there is a difference in the degree of aging.

배터리(20)의 교환은 단일 사업장 내의 전동지게차와 같은 복수의 구동장치(10a,10b,10c;10)들 사이에서 이루어지는 것이고, 이러한 배터리(20)의 교환을 통해 배터리(20)의 노후화 정도를 균일화시킴으로써, 배터리(20)의 교체시점을 동일한 시점으로 맞출 수 있다.The replacement of the battery 20 is made between a plurality of driving devices 10a, 10b, 10c; 10, such as an electric forklift in a single workplace, and the degree of deterioration of the battery 20 is reduced through the replacement of the battery 20. By equalizing, the replacement time of the battery 20 can be matched to the same time point.

이는 배터리(20) 교체를 단일 사업장 내에서 복수의 구동장치(10a,10b,10c;10)에 대해 일시에 전체를 진행할 수 있으므로, 단일 사업장 내에서 각각 별도로 다른 시기에 배터리(20)가 순차적으로 교체되는 것에 비해, 관리를 용이하게 하고 교체작업을 효율화시킬 수 있으며, 각 사업장에서도 빈번한 배터리(20) 교체에 따른 번잡한 업무의 발생을 최소화시킬 수 있다.This is because the battery 20 can be replaced at a time for a plurality of driving devices 10a, 10b, 10c; 10 in a single workplace, so that the batteries 20 are sequentially replaced at different times in a single workplace. Compared to replacement, it is possible to facilitate management and make replacement work efficient, and it is possible to minimize the occurrence of troublesome work due to frequent replacement of the battery 20 in each workplace.

배터리(20)의 노후화 정도는 배터리(20)의 충전횟수를 고려할 필요가 있고, 배터리(20)의 충전횟수는 배터리(20)의 열화와 상관관계가 있으므로 배터리(20)의 충전횟수에 의해 노후화 정도를 추정할 수 있다.The degree of deterioration of the battery 20 needs to consider the number of charging times of the battery 20 , and since the number of charging times of the battery 20 is correlated with the deterioration of the battery 20 , aging is caused by the number of charges of the battery 20 . extent can be estimated.

도 3은 배터리(20)의 충전용량유지율(%)과 배터리(20)의 충전횟수의 상관관계를 나타내는 것으로서, 수평축은 배터리(20)의 충전회수를, 수직축은 배터리(20)의 용량유지율 즉, 현재용량 대 초기용량을 나타낸다.3 shows the correlation between the charge capacity retention rate (%) of the battery 20 and the number of times the battery 20 is charged, the horizontal axis represents the number of times the battery 20 is charged, and the vertical axis represents the capacity retention rate of the battery 20, that is, , represents the current capacity versus the initial capacity.

여기서, 충전횟수는 배터리(20) 충전률이 약 80%에서 100%의 상태에서부터 충전률이 10% 이하의 상태가 된 후, 약 80%에서 100%의 상태로 다시 충전되는 것을 1사이클로 계산하였다.Here, the number of times of charging is calculated as one cycle of charging the battery 20 from a state of about 80% to 100% to a state of a charge rate of 10% or less, and then charging it again from a state of about 80% to 100%. .

도 3을 참조하면, 충전횟수가 증가함에 따라 충전용량유지율이 점차 감소하고, 충전횟수에 따른 충전용량유지율이 실험적으로 수치로 산출될 수 있으며, 초기 충전용량에 대한 현 충전용량의 비율이 낮을수록 배터리(20)의 노후화 정도가 높음을 의미한다.Referring to FIG. 3 , the charging capacity retention rate gradually decreases as the number of charging increases, and the charging capacity maintenance rate according to the number of charging can be experimentally calculated as a numerical value. As the ratio of the current charging capacity to the initial charging capacity is lower, the It means that the degree of aging of the battery 20 is high.

한편, 배터리(20)의 노후화정도를 추정할 수 있는 다른 방법으로서, 전류센싱모듈(34) 및 전압센싱모듈(35)을 이용하여, 충전 시 배터리(20)전압 V1과, 충전종료 시의 배터리(20)전압 V2와, 충전전류 적산량 ∑I를 포함한 충전정보를 획득하고, 그것의 충전정보와 충전율-개방회로전압(SOC-OCV) 특성을 기초로 노후화정도를 추정할 수 있다.On the other hand, as another method for estimating the degree of deterioration of the battery 20, using the current sensing module 34 and the voltage sensing module 35, the voltage V1 of the battery 20 during charging and the battery at the end of charging (20) It is possible to obtain charging information including the voltage V2 and the accumulated charging current ∑I, and estimate the degree of aging based on the charging information and the charging rate-open circuit voltage (SOC-OCV) characteristic.

충전율-개방회로전압 특성은 배터리(20)의 전체 충전용량에 대한 남은 용량의 비율인 충전율(SOC)과 배터리(20)의 개방회로전압(OCV)과의 상관관계를 표시하는 것이다.The charge rate-open circuit voltage characteristic indicates the correlation between the charge rate (SOC), which is the ratio of the remaining capacity to the total charge capacity of the battery 20 , and the open circuit voltage (OCV) of the battery 20 .

도 4를 참고하면, 배터리(20)의 충전율(SOC)이 증가함에 따라 개방회로전압(OCV)이 증가하는 상태를 그래프로 나타내는 것으로서, 배터리(20)의 개방회로전압(OCV)으로부터 충전율(SOC)을 얻을 수 있다.Referring to FIG. 4 , as a graph showing a state in which the open circuit voltage (OCV) increases as the charge rate (SOC) of the battery 20 increases, the charge rate (SOC) from the open circuit voltage (OCV) of the battery 20 ) can be obtained.

따라서, 충전개시시의 배터리(20)의 개방회로전압 V1으로부터 충전개시시의 충전율 SOC1을 구하고, 충전종료시의 배터리(20)의 개방회전전압 V2로부터 충전종료시의 충전율 SOC2를 구한 후, 상기 충전전류 적산량 ∑I을 이용하여, 충전용량을 구할 수 있다.Accordingly, the charging rate SOC1 at the start of charging is obtained from the open circuit voltage V1 of the battery 20 at the start of charging, and the charging rate SOC2 at the end of charging is obtained from the open circuit voltage V2 of the battery 20 at the end of charging. Using the integrated amount ∑I, the charging capacity can be calculated.

충전용량 = 100× ∑I ÷ (SOC2-SOC1) Charging capacity = 100× ∑I ÷ (SOC2-SOC1)

위 계산식에 의한 충전용량이 초기의 충전용량의 몇 %인지를 계산하여 비율을 산출함으로써, 배터리(20)의 노후화 정도를 추정할 수 있다.The degree of deterioration of the battery 20 can be estimated by calculating the ratio by calculating what % of the charging capacity according to the above formula is the initial charging capacity.

본 실시예에서 배터리(20)의 노후화 정도를 산출하기 위하여, 위의 2가지 방법 중 어느 것을 선택적으로 사용할 수 있으나, 산출과정의 오류를 감소시키고 배터리(20) 교환시기 계산의 정확도를 보다 높일 수 있도록 하기 위해, 위 2가지 방법을 사용하여 평균적 노후화 정도를 산출한다.In this embodiment, in order to calculate the degree of deterioration of the battery 20, any of the above two methods may be selectively used, but it is possible to reduce the error in the calculation process and increase the accuracy of the calculation of the battery 20 replacement time. In order to do so, the average degree of aging is calculated using the above two methods.

즉, 첫 번째 방법에 의해 배터리(20)의 충전횟수와 관련하여 초기 충전용량 대비 현 충전용량의 비율1을 산출하고, 두 번째 방법에 의해 충전율-개방회로전압 특성에 따라 초기 충전용량 대비 현 충전용량의 비율 2를 산출한 후, 비율1과 비율2를 평균하여 평균비율을 산출한다.That is, according to the first method, the ratio 1 of the initial charge capacity to the current charge capacity is calculated in relation to the number of times the battery 20 is charged, and by the second method, the current charge compared to the initial charge capacity is calculated according to the charge rate-open circuit voltage characteristic. After calculating the ratio 2 of the capacity, the ratio 1 and the ratio 2 are averaged to calculate the average ratio.

상기 평균비율을 노후화 정도에 대한 기초수치로 사용함으로써 보다 정확하고 효과적인 판단이 이루어질 수 있다.By using the average ratio as a basic value for the degree of aging, more accurate and effective judgment can be made.

한편, 관리서버(70)는 배터리(20)의 상태정보에 의해 각 배터리(20)의 노후화 정도를 산출한 후, 단일 사업장에서 각 배터리(20)의 노후화 순위를 결정한다.Meanwhile, the management server 70 calculates the degree of deterioration of each battery 20 based on the state information of the battery 20 , and then determines the aging ranking of each battery 20 in a single workplace.

즉, 단일 사업장의 복수의 구동장치(10a,10b,10c;10)에 장착된 배터리(20)를 노후화 정도가 높은 순에 따라 순위를 산출하는 것으로서, 예컨대 단위사업장에서 운용되는 11개의 배터리(20)가 1위부터 11위까지의 순위로 결정될 수 있다.That is, the ranking of the batteries 20 installed in the plurality of driving devices 10a, 10b, 10c; 10 of a single business site is calculated in the order of the highest degree of deterioration, for example, 11 batteries 20 operated in a unit business site. ) can be determined in a ranking from 1st to 11th.

이 후, 결정된 순위에 따라 평균보다 노후화 정도가 높은 배터리(20)와, 평균보다 노후화 정도가 낮은 배터리(20)를 서로 일대일로 매칭시킨 배터리교환정보를 생성한다.Thereafter, battery exchange information is generated in which the battery 20 having a higher degree of aging than the average and the battery 20 having a lower degree of aging than the average are matched one-to-one according to the determined ranking.

즉, 위의 순위에서 6위가 평균순위에 해당하므로, 1위~5위의 배터리(20)를 11위~7위의 배터리(20)와 순차적으로 일대일로 매칭시킨 배터리교환정보, 예컨대 1위와 11위, 2위와 10위, 3위와 9위와 같이 배터리교환정보를 생성하는 것이다.That is, since the 6th place in the above ranking corresponds to the average ranking, battery exchange information that sequentially matches the batteries 20 in the 1st to 5th places with the batteries 20 in the 11th to 7th places sequentially one-to-one, for example, with the first It is to generate battery exchange information as in 11th, 2nd and 10th, 3rd and 9th.

관리서버(70)는 생성된 배터리교환정보를 통신을 통해 사업장의 관리자단말기(80)에 전송하고, 각 단위사업장의 관리자는 배터리교환정보를 참고하여 단위사업장 내에서 복수의 구동장치(10a,10b,10c;10)로부터 각 배터리(20)를 인출하고 배터리교환정보에 따라 서로 교환하여 배터리(20)를 재장착시킨다.The management server 70 transmits the generated battery exchange information to the manager terminal 80 of the business site through communication, and the manager of each unit business site refers to the battery exchange information to a plurality of driving devices 10a and 10b in the unit business site. 10c;

이러한 배터리(20)의 교환장착은 배터리(20)의 교체주기 내에서 2~4회 배터리교환정보를 제공하여 서로 교환 및 재장착이 이루어지도록 하는 것이 바람직하다.It is preferable to exchange and remount the battery 20 by providing battery exchange information 2 to 4 times within the replacement cycle of the battery 20 so that the exchange and remounting of the battery 20 are performed.

이에 따라, 단일 사업장 내에서 사용되는 복수의 배터리(20)의 노후화 정도를 대략 균일하게 맞출 수 있고, 이는 하나의 시점에 단일 사업장의 복수의 배터리(20)의 노후화 정도를 균일화시키고, 단일 사업장 내에서 전체적으로 한 번에 배터리(20) 교체작업이 가능하도록 한다.Accordingly, it is possible to approximately uniformly match the degree of aging of the plurality of batteries 20 used in a single workplace, which equalizes the degree of aging of the plurality of batteries 20 in a single workplace at one point in time, and within a single workplace In this way, it is possible to replace the battery 20 at a time as a whole.

결국, 배터리교환정보에 의해 배터리(20)의 교체작업을 효율화시키고 노후화의 과정도 서로 보조를 맞추게 하여 관리를 용이하게 하며, 개별 배터리(20)가 서로 노후화에 차이가 큰 경우에 발생할 수 있는 빈번한 교체작업, 빈번한 점검방문의 문제를 경감시킬 수 있다.As a result, the replacement operation of the battery 20 is made efficient by the battery replacement information, and the aging process is also made to keep pace with each other to facilitate management, and frequent occurrences that may occur when the individual batteries 20 have a large difference in aging. The problem of replacement work and frequent inspection visits can be alleviated.

한편, 도 5를 참고하면, 관리자단말기(80)에 배터리교환정보가 전송되고, 관리자가 단위사업장 내에서 복수의 구동장치(10a,10b,10c;10)로부터 각 배터리(20)를 인출하고 배터리교환정보에 따라 서로 교환하는 작업이 이루어지는 시점에서, 관리서버(70)는 사업장의 관리자가 배터리 교환작업을 용이하고 정확하게 수행할 수 있도록 실시간으로 교환가이드모드를 진행시킬 수 있다. Meanwhile, referring to FIG. 5 , battery exchange information is transmitted to the manager terminal 80 , and the manager withdraws each battery 20 from a plurality of driving devices 10a, 10b, 10c; At the point in time when the work of exchanging each other according to the exchange information is made, the management server 70 may advance the exchange guide mode in real time so that the manager of the workplace can easily and accurately perform the battery exchange task.

이를 위해, 각 상기 구동장치(10)에는 제어부(50)에 의해 제어되는 표시수단(14)이 설치되어 교환가이드모드를 보조한다.To this end, each of the driving devices 10 is provided with a display means 14 controlled by the control unit 50 to assist the exchange guide mode.

즉, 관리자단말기(80)에 배터리교환정보가 도착하고 특정사업장의 관리자가 배터리(20) 교환작업에 대한 선택신호를 관리자단말기(80)로부터 관리서버(70)로 전달 시, 관리서버(70)는 교환가이드모드를 진행시킨다. That is, when battery replacement information arrives at the manager terminal 80 and the manager of a specific business site transmits a selection signal for the battery 20 exchange operation from the manager terminal 80 to the management server 70, the management server 70 moves the exchange guide mode.

이는 하나의 구동장치(10)에서 배터리(20)를 인출 시, 그 구동장치(10)의 제어부(50)가 배터리(20)의 분리상태를 통신부(40)를 통해 실시간으로 관리서버(70)로 전달하고, 관리서버(70)는 배터리교환정보에 따라 매칭된 구동장치(10)의 표시수단(14)이 알림음 또는 알림불빛을 출력하도록, 제어신호를 실시간으로 통신부(40)를 통해 매칭된 구동장치(10)의 제어부(50)로 전송한다.This means that when the battery 20 is withdrawn from one driving device 10, the control unit 50 of the driving device 10 detects the disconnection state of the battery 20 in real time through the communication unit 40 to the management server 70 and the management server 70 matches the control signal through the communication unit 40 in real time so that the display means 14 of the driving device 10 matched according to the battery replacement information outputs a notification sound or a notification light. transmitted to the control unit 50 of the driven device 10 .

이에 따라, 작업장의 관리자는 알림음 또는 알림불빛이 출력되는 구동장치(10)에서도 배터리(20)를 인출하여 기 인출한 배터리(20)와 서로 바꾸는 교환장착이 이루어진다.Accordingly, the manager of the workplace takes out the battery 20 from the driving device 10 from which a notification sound or a notification light is output, and exchanges and installs the previously drawn battery 20 with each other.

이러한 과정은, 배터리(20) 교환대상이 되는 하나의 구동장치(10)에서 배터리(20)의 인출이 이루어질 때마다 그것과 매칭된 다른 구동장치(10)의 표시수단(14)이 알림음 또는 알림불빛을 출력되도록 하여, 작업자가 매칭된 구동수단을 쉽게 인지하도록 하고, 서로 매칭된 구동수단끼리 배터리(20)의 교환이 정확하고 원활히 이루어질 수 있다.In this process, whenever the battery 20 is withdrawn from one driving device 10 to be replaced with the battery 20, the display means 14 of the other driving device 10 matched with the beep sounds or By outputting a notification light, the operator can easily recognize the matched driving means, and the battery 20 can be accurately and smoothly exchanged between the matched driving means.
