Prototipo de una estación de auto-lavado utilizando sistemas de control inteligente

Abstract

ABSTRACT The objective of the research was to develop, implement and provide an adequate and innovative automatic payment tool for a prototype of a self-cleaning station, focused on new technologies applied to business models, has web pages, for access to service by the users of the vehicles, also with an emergency warning system by means of an SMS alert message, the payment is made through an online payment system and the monitoring of the process and condition of the equipment was used the same web platform and an HMI screen. The research focuses on the application of cutting-edge technology in the sector and national industry with efficiency and quality. For the development of the proposed system, an s7-1200 1214 PLC was used, in addition a KMI 600 HMI screen was programmed with the SIMATIC STEP7 software (TIA portal V13) .For writing and reading data from the PLC to the web pages, The Python programming language is used and communicates with the Raspberry Pi via the Ethernet S7 protocol, with an average time of 2.16 seconds in writing data and reading 860 milliseconds, from the web pages created to the PLC that controls the prototype of the Auto-wash station. The user has the facility to select between two types of washing the single and double and subsequently liquidates the service, with his credit card on the PayPal online payment platform, and finally the platform is used to send the alert message of communications and messaging Twilio.
