Automated Quality Control

The purpose of the work is to develop an automated quality control system for welded joints of cable car structures designed and manufactured at the Skado LLC enterprise (Samara) in order to improve the quality of control. The analysis of requirements for welded structures and welded joints of cable cars is carried out, methods of control of welded joints are considered. A block diagram of an automated system for quality control of welded joints based on the method of ultrasonic testing has been developed. The analysis of ultrasonic sensors on phased arrays is carried out. The sensors and actuators of the system are selected. A scheme for interfacing system elements with a programmable logic controller has been developed. The structure of the system and the scheme of interfacing the system elements with the programmable logic controller are described. A method for performing control has been developed.

AbstractIndonesian Low-Speed Tunnel (ILST) has been in operation since February 1987, whose operation is supported by 10 units of the ILST-facility plant, each ILST-facility plant works according to its duties and can be operated locally (onsite) and remotely (from control room/control desk). Local and remote Operations are made possible by system control’s installation at each ILST-facility plant. The control systems used are the Programmable Logic Controller (PLC), which is installed at each -ILST facility plant as local PLC and central PLC.For remote operations, a communication module is installed at local and central PLC. The PLC used by ILST was SATTControl running CPM operating system which is not commonly used anymore, and the spare parts are difficult to find because the PLC manufacturers have confirmed that they no longer provide technical support or spare parts since 2001.To ensure ILST’s continues operations, ILST’s control system update is carried out. The updates include old PLC checks, new locally available PLC surveys, compatibility with existing PLCs, windows-based hardware and software flexibility, inter PLCs communication, system’s reliability and suited with yearly available budget.Keywords: ILST system control, PLCAbstrakIndonesian Low Speed Tunnel (ILST) telah beroperasi sejak Pebruari 1987, dimana dalam operasinya didukung oleh 10 unit plant fasilitas-ILST, dimana plant fasilitas-ILST bekerja sesuai tugas plant masing-masing dan dapat dioperasikan secara local control (onsite) dan secara remote dari ruang kontrol (desk control). Pengoperasian secara local dan remote tersebut dimungkinkan dengan pemasangan kontrol sistem pada masing-masing plant fasilitas-ILST, kontrol sistem yang digunakan adalah Programmable Logic Controller (PLC), yang dipasang di tiap plant fasilitas-ILST sebagai local PLC dan central PLC.Untuk operasi remote dimana dipasang module komunikasi pada local dan central PLC. PLC yang digunakan ILST adalah SATTControl yang menggunakan operating system CPM yang tak umum lagi digunakan saat ini dan sulit mencari spare part karena produsen PLC telah mengkonfirmasi bahwa tak ada lagi dukungan teknis dan spare parts sejak tahun 2001.Untuk kelangsungan operasi ILST dilakukan pembaruan kontrol sistem ILST, pembaruan meliputi pemeriksaan PLC lama, survey PLC baru di dalam negeri, kecocokan dengan PLC existing, flexibilitas hardware dan software yang berbasis windows, komunikasi antar PLC, kehandalannya dan sesuai dengan dana yang diperoleh tiap tahun.Kata kunci: control system ILST, PLC

This article investigates an inverted pendulum on a mobile cart (mobile inverted pendulum) controlled via a programmable logic controller and actuated by a double-acting pneumatic cylinder. The study is conducted both theoretically, by modeling and simulating the entire system, and experimentally, using a specially developed test bench. Four low-cost 2/2 proportional valves are used for cylinder control. The control architecture consists of two nested control loops with proportional–integral–derivative compensators. To reduce cost, a programmable logic controller was used to manage both the system control and data acquisition. The results of the simulations carried out using linear and nonlinear models of the system were validated by comparison with those obtained experimentally.
