Objective

There are several objectives in order to complete this “development and design Early Warning Fault Detection System”. The objectives are:-

Ø  To prevent the motor from damage because overload current.
Ø  To get the measuring of RPM for the motor during the motor is on the fault condition.
Ø  To generate report during equipment tripping via SMS by using the GSM.

In designing the prototype of development and design Early Warning Fault Detection System, Proteus software is used to design the layout of Printed Circuit Board.

To integrate between phones functionally with, the simulation of Proteus software will represent the right output of simulation result before getting the real output from hardware part. 



Introduction

The demand of reliable and high quality power electricity is widely required by industry and construction sector. The development of information and communication technology also increased as a large number of electrical users. Early Waning Fault Detection System is designed for motor in industry by combining 1 major device which is Short Message Service (SMS) by using the GSM. This device has their own function in order to communicate each other to create one complete system in industry.

            Early Warning Fault Detection System is design and develops for motor or machine protection in industry. Development and design Early Warning Fault Detection System is a project that used in industrial. This project mainly used in industrial at the machine or motor. This project are design to prevent the motor from damage because overload current. With this system, the motor will be saving from damage. This is because we are used magnetic contactor and overload relay. Magnetic contactor is used to start electrical motor because it can prevent damage to the motor in event the motor gets jammed or overload.  Overload relays are electrical switches typically employed in industrial settings to protect electrical equipment from damage due to overheating in turn caused by excessive current flow. In this project also miniature circuit breaker are used for protecting and controlling the electricity supply to respective electrical circuits. Circuit breakers protect electrical circuitry from damage due to an over current condition, such as an overload condition or a relatively high level short circuit or fault condition. Besides that, this project also will generate report during equipment tripping with SMS by using the GSM. This happen when there are overload current, the supply from machine or motor will automatic trip and sent the report by using the GSM to the phone with SMS. So with this, technician will be informing early.

            For the project of the Early Warning Fault Detection System is base on the speed of the motor which is from the monitoring the motor by using speed drive (inverter) it can make a fault. The fault happens from the different of RPM motor. When the speed motor has been adjust the main board will process as a overload current then it will trip directly. For this condition the speed sensor will collect data of the RPM motor to send the controller PIC and make a data logger at the PC. The controller will send the data to GSM to send the phone. Actually many of factory use motor in all aspects, from that the condition of the motor will be change depends on the load, current and others thing. This device is to improve of the fault in the industries by checking their speed of the motor (RPM).

Actually this system are design and develop with no risk to customer, save time, energy and easy to use. Since almost every person have mobile phone and carries most of the time this project used a Short Message Services (SMS) to communicate with user quickly. With a mobile phone, the user can read SMS massage at any time.

            Block diagram description

            Firstly is the input 240V, 240V will supply the voltage to the main board circuit. The main board circuit will receive the 240V to function the miniature circuit breaker (MCB), magnetic contactor and thermal overload relay. On the main board circuit, has a transformer to step down the voltage from 240V to 12V before the 12V supply the motor DC. When the motor DC starts running, there is speed drive (inverter) as a controller the speed of the motor. The inverter will make changing of the speed motor from normal, fast, slow and stop. The inverter will make the main board trip and make the PIC send the data. The speed of motor has record from the speed sensor that use to read the speed motor. For the speed motor, optical speed sensor type is more efficiency than others. From the reading of the speed sensor it will send the data of speed to PIC (RS 232). PIC is one of the important part to make sure the fault is happen. In the PIC, it will control the GSM and the data logger at the PC. The data in a C language will send to the GSM that has program to make sure the GSM can read it. GSM will program the data that will send to the phone. The output of this Early Warning Fault Detection System is the phone and the technician or the engineer will receive the data fault. The data of speed motor also receive to the PC data logger. The engineer can read all the data about the speed motor from the data logger.
