Concepção de um sistema de monitoramento GSM de nível de água em reservatórios, bombas de água e do gerador de energia eléctrica em uma residência

Abstract

The substitution of human labor, in favor of safety of people, quality of products, eficient production or cost reduction is directly related to the concept of automation. Residential automation for example, concerns a set of technologies with the ability to sche- dule events in a house and make automatic operation of various equipment. The objective is to offer simplicity and more practicality to residents through remote control and mana- gement of the residence and this is done through a simple mobile device, being able to control the home appliances from anywhere you are. For this control to be possible, it is necessary a use of controller that meets the demands of the system to be controlled. For the specific case of this project, a CWT5112 Remote Terminal Unit is used, which is an equipment that interfaces objects in the physical field with a distributed control system or SCADA system, transmitting telemetry data to a master supervision system to control or monitor the operation of connected objects. This controller is connected to level sensors, generator status relays and lifting pump con- trol units (Pump that raises the water from the underground tank network to the filtered water tank, immediately after the filtering process) and the pressure pump control unit (Pump that ensures the ideal water pressure for the entire hydraulic system of the resi- dence) being these the elements to be controlled by RTU. According to the configurations made in the RTU, when it detects the presence or absence of the activation signal in its input terminals (whether digital or analog), it must notify by means of an SMS message, the deviation or anomaly previously established to the con- tact groups configured in the system.
