이하, 도면을 참고로 본 발명에 따른 구성요소를 바람직한 일 실시예에 의거하여 설명하면 다음과 같다.Hereinafter, the components according to the present invention will be described with reference to the drawings based on the preferred embodiment.

도 1을 참조하면, 본 발명에 따라 하이브리드, 전기차 모터 제어기의 작동 성능을 검증하는 에이징 검사기(10)는 랙 타입의 산업용 컴퓨터를 사용하고, 기설치된 프로그램을 통해 에이징 지그(20)에 안착된 제어기(40)의 작동 성능을 검증하는 것을 특징으로 하며, 상기 에이징 지그(20)와는 하네스로 연결한다. 에이징 검사기(10)는 CAN(Controller Area Network) 통신 방식을 이용하여 제품(제어기)에 검사 명령을 전송하고 검사 결과를 수신한다. 에이징 검사기(10)는 하나 뿐만 아니라 여러 대의 제품과 연결되어 동시에 검증할 수 있다. 바람직하게는 장비 및 제품 보호를 위한 퓨즈(fuse)나 폴리스위치(poly switch)를 사용하고, 장비의 과열을 방지하기 위해 칠러 또는 냉각 팬의 사용을 철저히 하는 것이 좋다. 또한 전체 공정의 관리를 위한 소프트웨어를 설치하여 복수의 제품 각각에 대한 상태를 수신하고, 작업 진행 시간 및 진행률을 작업자에게 표시하며, 검사 결과의 데이터를 저장하는 기능을 갖도록 한다.1, the aging checker 10 for verifying the operating performance of the hybrid, electric vehicle motor controller according to the present invention uses a rack-type industrial computer, the controller seated on the aging jig 20 through a pre-installed program Characterized in verifying the operating performance of the 40, it is connected to the aging jig 20 in a harness. The aging checker 10 transmits a test command to a product (controller) and receives a test result using a controller area network (CAN) communication method. Aging checker 10 may be connected to a number of products as well as one and can be verified at the same time. Preferably, a fuse or poly switch is used to protect the equipment and products, and the use of a chiller or a cooling fan should be thoroughly used to prevent overheating of the equipment. In addition, by installing the software for the management of the entire process to receive the status for each of a plurality of products, to show the work progress time and progress to the operator, and to have the function of storing the data of the inspection results.

제품을 물리적으로 안착하고 제품을 상기 에이징 검사기(10)와 전기적으로 연결해주는 에이징 지그(20)는 고정선반(fixture) 부분과 와이어로 구성되어 있다.The aging jig 20 which physically seats the product and electrically connects the product with the aging checker 10 is composed of a fixture part and a wire.

고온 챔버(30)는 내부에 제품 자체, 또는 제품이 안착된 상기 에이징 지그(20)를 수납하고 제품 내부 부품의 온도를 80도 내지 90도로 균일화하는 기능을 갖는 것을 특징으로 한다. 고온 챔버(30)는 에이징 지그(20)를 수납하여 고온 챔버(30) 내에서 에이징 지그(20)에 안착된 제품의 전체 테스트를 진행하는 것이 이상적이나, 고온 챔버(30)가 제품만을 수납하고 테스트 시에는 제품을 반출하여 테스트를 하더라도 소기의 목적을 달성할 수 있다.The high temperature chamber 30 has a function of accommodating the product itself, or the aging jig 20 on which the product is placed, and equalizing the temperature of the product internal parts to 80 degrees to 90 degrees. The high temperature chamber 30 is ideally to accommodate the aging jig 20 to perform a full test of the product seated on the aging jig 20 in the high temperature chamber 30, but the high temperature chamber 30 receives only the product In testing, even if the product is taken out and tested, the desired purpose can be achieved.

상기 고온 챔버(30)가 제품만을 수납하도록 제작된 경우, 고온 챔버(30)는 다수의 분리된 고온실로 구성되어 제품의 열처리를 각기 진행하도록 한다. 고온 챔버(30)의 내부에는 온도 모니터링용 센서가 설치된다. 바람직하게는 제품의 온도가 목표 온도에 도달하기 전에 제품이 반출되지 않도록 잠금(lock) 장치를 설치하고, 다수의 제품 각각에 대한 동작상태 및 완료상태를 알 수 있도록 램프(lamp)를 설치한다.When the high temperature chamber 30 is manufactured to receive only the product, the high temperature chamber 30 is composed of a plurality of separate high temperature chambers to allow the heat treatment of the product to proceed. The temperature monitoring sensor is installed inside the high temperature chamber 30. Preferably, a lock device is installed to prevent the product from being discharged before the temperature of the product reaches the target temperature, and a lamp is installed to know the operation state and the completion state of each of the plurality of products.

상기와 같이 구성되는 본 발명에 따른 바람직한 일 실시예의 작동방법을 설명하면 다음과 같다.Referring to the operation method of a preferred embodiment according to the present invention configured as described above are as follows.

도 3을 참조하면, 에이징을 위해서 먼저 검사 대상 제품을 고온 챔버(30) 내에서 내부 부품의 온도를 높여 80도 내지 90도로 균일화되도록 한다[제1단계(S10)]. 균일화가 완료된 제품은 에이징 검사기(10)의 전원이 인가된 상태에서 에이징 지그(20)에 안착하고(아직 안착이 되지 않았을 경우) 에이징 검사기(10)와 전기적으로 연결한다[제2단계(S20)].Referring to FIG. 3, first, the product to be inspected is equalized to 80 to 90 degrees by increasing the temperature of internal components in the high temperature chamber 30 for aging (first step S10). After completion of the homogenization, the product is seated on the aging jig 20 in the state where the power of the aging inspector 10 is applied (when not yet mounted) and is electrically connected to the aging inspector 10 (second step S20). ].

에이징 검사기(10)와 제품이 전기적으로 연결되면 에이징 지그(20)는 시작 신호를 에이징 검사기(10)로 전송하고 에이징 검사기(10)는 제품에 동작 전압을 인가하고 설정된 과정에 따라 제품을 구동하며 검사를 진행하게 된다.When the aging checker 10 and the product are electrically connected, the aging jig 20 transmits a start signal to the aging checker 10 and the aging checker 10 applies an operating voltage to the product and drives the product according to a set process. The test will proceed.

에이징 검사기(10)는 CAN(Controller Area Network) 통신을 통해 제품에 명령을 전송하고 결과 데이터를 수신한다(도 4 참조). 그러나 제품에는 각종 센서 신호 입력부와, 각종 엑츄에이터(릴레이)를 구동시키는 출력부가 존재하므로, 실제 차량 상태를 모사하여 제어기를 구동시키기 위하여 상기 입출력부에 전압, 전류, 스위치 신호 및 로드 연결 등 실제 입출력 부하들을 모사하여 연결해주어야 한다.The aging checker 10 transmits a command to the product through a controller area network (CAN) communication and receives the result data (see FIG. 4). However, since there are various sensor signal input parts and output parts for driving various actuators (relays), the actual input / output loads such as voltage, current, switch signals, and load connections such as voltage, current, switch signals, and loads are connected to drive the controller by simulating the actual vehicle state. You must connect them by copying them.

상기 에이징 검사기(10)는 연결된 제품의 메모리 영역에 검사를 위한 프로그램을 다운로드한다[제3단계(S30)].The aging checker 10 downloads a program for inspection to a memory area of the connected product (step S30).

다음으로 제어기(40)에 실제 차량을 운행하는 것과 동일한 입출력 조건과, 차량이 충분한 거리를 운행한 효과를 내기 위한 가속 조건을 가한다[제4단계(S40)]. 즉, 강제로 제품 내 회로를 구동하지 않고 제품이 실제로 차량에 장착되었을 때 운전자가 시동을 걸고 차량을 운행하는 것과 동일한 입출력 조건을 제공함으로써 제품 내부의 실제 차량 운행용 소프트웨어가 실행되도록 한다. 또한 초기 불량이 충분히 검출되도록 차량이 충분한 거리를 운행한 듯한 효과를 위하여 15분 내지 25분 동안 가속 조건을 가하는데, 이것은 상기 에이징 검사기(10)가 제어기(40)에서 자동차의 모터를 제어하기 위해 출력되는 PWM(Pulse Width Modulation) 신호의 듀티(Duty)를 0% 내지 100%에서 선형적으로 증감시키는 동작을 15분 내지 25분 간 지속하도록 명령함으로써 이루어진다. 이때 상기 에이징 검사기(10)와 상기 제어기(40)의 통신에 있어서는 CAN(Controller Area Network) 방식을 이용하여 검사 명령을 전송하고 출력 조건 등의 결과를 수신할 수 있도록 한다.Next, the controller 40 applies the same input / output conditions as those for driving the actual vehicle and acceleration conditions for the effect that the vehicle has traveled a sufficient distance (fourth step S40). That is, the actual vehicle driving software inside the product is executed by providing the same input and output conditions as the driver starts and operates the vehicle when the product is actually mounted on the vehicle without forcing the circuit in the product to be forced. In addition, the acceleration condition is applied for 15 to 25 minutes for the effect that the vehicle has traveled a sufficient distance so that the initial failure is sufficiently detected, which means that the aging checker 10 controls the motor of the vehicle in the controller 40. The operation of linearly increasing or decreasing the duty of the output Pulse Width Modulation (PWM) signal from 0% to 100% is performed for 15 to 25 minutes. At this time, in the communication between the aging checker 10 and the controller 40, a test command can be transmitted using a controller area network (CAN) method and a result such as an output condition can be received.

상기 과정(제4단계)과 동시에 에이징 검사기(10)는 제품의 입출력을 모니터링하게 된다[제5단계(S50)]. 검사를 진행하는 소프트웨어는 검사 진행에 대한 조작 명령을 에이징 지그(20)에 송신하고, 수신된 여러 채널에 안착된 제품 각각에 대한 상태(Ready/Run/OK 또는 NG)와, 작업 진행 시간 및 진행률을 작업자에게 표시하며, 검사 결과(판정 결과)의 데이터를 저장하는 기능을 갖는다.At the same time as the process (step 4), the aging checker 10 monitors the input and output of the product (step 5 (S50)). The software that conducts the inspection sends an operation command for the inspection progress to the aging jig 20, the status (Ready / Run / OK or NG) for each of the products seated on the various channels received, the work progress time and progress rate. Is displayed to the operator, and has the function of storing data of the inspection result (decision result).
