Abstract
피엘씨를 사용하는 엘리베이터 제어시스템에 통신방식을 도입하여 신호선의 수량을 줄이고 현장 작업 공수를 감소하여 원가를 절감하고 제품의 구성을 보다 간략하게 할 수 있게된다.By adopting a communication method to the elevator control system using PLC, it is possible to reduce the number of signal lines and reduce the number of field work to reduce the cost and to simplify the configuration of the product.
Description
피엘씨로 제어되는 엘리베이터는 마이컴 방식과는 달리 입출력의 신호의 대부분을 제어반에서 직접 개별적으로 제어하므로 카측이나 승강장측으로 가는 승강로상의 신호선들이 대단히 많이 소요된다. 특히 5~8개층 이상의 건물에 사용되는 엘리베이터의 경우 층이 증가하면서 기하급수적으로 늘어나는 제어선을 감당하기 어려울뿐만 아니라 수많은 신호선으로 이루어진 시스템이 잦은 고장을 일으키는 원인이 되기도 한다.Unlike the microcomputer, elevators controlled by PLC control most of the input and output signals directly from the control panel so that the signal lines on the hoistway to the car side or the platform side are very large. In particular, elevators used in buildings with more than 5 to 8 floors are difficult to handle exponentially increasing control lines as the floors increase, and a system composed of numerous signal lines can cause frequent failures.
피엘씨를 이용하여 제어되는 엘리베이터 제어시스템에서도 마이컴 엘리베이터 제어시스템처럼 통신을 이용하여 시스템의 신뢰도를 높이고 신호선의 사용량을 대폭적으로 줄여 전체의 비용을 절감할 뿐만 아니라 향후 발생이 예상되는 선로 불량에 의한 고장까지 방지하고자 한다.In the elevator control system that is controlled by PLC, the communication control is used like the microcomputer elevator control system to increase the reliability of the system and drastically reduce the usage of signal lines, thereby reducing the overall cost and even the failure caused by the failure of the line that is expected to occur in the future. To prevent it.
또한, 설치인건비가 파격적으로 줄어들므로 설치 및 유지보수를 위한 비용이 줄어들어 산업 전반적으로 부가가치의 향상이 예상된다. 통신을 적용하므로 생기는 예상되는 시간의 지연은 타이머를 이용한 주기 인트럽트와 제어명령의 일괄전송방식을 채택하여 보완하고자 한다. In addition, installation labor costs are dramatically reduced, and thus, costs for installation and maintenance are reduced, and the value added of the industry is expected to be improved. The delay of the expected time caused by the application of the communication is compensated by adopting a cycle interrupt using a timer and a batch transfer of control commands.
본 고안은 엘리베이터 전체 제어를 주관하는 피엘씨(가)와, 피엘씨(가)와 카통신부(마) 및 각층 승강장 통신부(바,사)와 통신 중계를 담당하는 통신 마스터(나)와 엘리베이터 카 내외부의 신호와 카 부름버튼 및 램프를 관장하는 카통신부(마)와 각층의 상하행 부름 버튼의 등록과 그 램프의 점,소등을 담당하는 승강장 통신부(바,사)로 구성된다.The present invention is the communication master (B) and elevator car in charge of communication relay with the PLC (A), the PLC (A) and the car communication unit (E) and the platform communication unit (bar, company) for each floor, which manages the whole elevator control. It consists of a car communication unit (e) which manages internal and external signals, car call buttons and lamps, and a platform communication unit (bar, company) that is responsible for registering up and down call buttons on each floor and turning off and off the lamps.
피엘씨(가)와 통신 마스터(나)는 서로 슬레이브와 마스터로 데이터를 요구하고 응답하는 방법으로 통신하며 서로 통신상태를 모니터링한다. 통신마스타(나)는 카통신부(마)와 승강장 통신부(바,사)로부터 인터럽트되는 데이터를 받아 피엘씨(가)로 전송하고 주기적으로 하부 시스템, 즉,카통신부 및 승강장통신부에 차례로 데이터를 요구하여 받아들이는 스캔 방식으로 운영한다.The PI and the communication master (B) communicate with each other by requesting and responding data to the slave and the master, and monitor the communication state with each other. The communication master (b) receives the interrupted data from the car communication unit (e) and the platform communication unit (bar, company) and transmits the data to the P.C., and periodically requests data from the lower system, that is, the car communication unit and the platform communication unit. It operates by accepting scan method.
피엘씨(가)의 제어변수에 따라 신속하게 하위 장치들을 제어하기 위하여 주기적 실행루틴을 반복적으로 실행하여 카통신부와 승강장통신부에서 제어지령을 수행할 수 있도록 한다. In order to control subordinate devices quickly according to the control variables of PLC, periodic execution routines are repeatedly executed so that the car communication unit and the platform communication unit can execute control commands.
통신선로는 통신마스타(나)와 카통신부(마) 사이는 주행케이블로 통신선(라)이 연결되며 통신마스타(나)와 승강장통신부(바,사) 사이에도 역시 같은 통신라인(아)을 통하여 데이터를 전송한다.The communication line is connected between the communication master (B) and the car communication unit (E) by the traveling cable (D). The communication line (B) is also connected between the communication master (B) and the platform communication unit (B). Send the data.
피엘씨의 직접 입출력방식으로 설계하면 24가닥의 신호선이 필요하지만 본 고안의 방법으로 통신시스템을 적용하면 통신선로를 통하여 데이터를 주고 받기 때문에 2가닥의 통신라인만 필요하게 되어 신호선의 결선작업량이 현저하게 줄어든다. 또한 이러한 구성의 잇점은 방송하는 것처럼 일괄전송의 경우 신속하게 반복적으로 전송하는데 편리하며 제어명령을 전 시스템의 구석구석까지 재빨리 전파하는데 유용하게 사용되며 전체적인 통신량을 줄이는데 기여할 수 있다. When designing by direct input / output method of PL, 24 signal lines are needed, but when applying the communication system according to the method of the present invention, only 2 lines are needed since data is transmitted and received through communication lines, so the wiring work of the signal lines is remarkable. Is reduced. In addition, the advantage of such a configuration is that it is convenient for quick and repeated transmission in the case of a batch transmission, such as broadcasting, it is useful to quickly propagate control commands to every corner of the entire system and contribute to reducing the overall traffic.
