Design And Construction Of A Machine Overheat Detection With SMS Alert

ABSTRACT

Malfunction or failure of mechanical, electrical and electro-mechanical equipment, for example equipment used in manufacturing operations, is often preceded by an increase in the operating temperature of at least some portion of the equipment. A temperature-sensitive, active material-containing actuator is pre-selected to operate at a pre- determined temperature indicative of impending equipment failure and placed in thermal contact with the equipment. If the equipment achieves the pre-selected temperature the actuator signals this by displaying a flag or providing some other passive visual indication. In this work a review of existing fire-detector types has been carried out along with the development of a low cost, portable, and reliable microcontroller based automated fire alarm system for remotely alerting any fire incidents in household or industrial premises. The aim of the system designed is to alert the distant property-owner efficiently and quickly by sending short message (SMS) via GSM network. A Linear integrated temperature sensor detects temperature beyond preset value. The sensor units are connected via common data line to ATMega AVR microcontroller. A SIM900A GSM kit based network module, capable of operating in standard GSM bands, has been used to send alert messages. The system is implemented on bread board and tested under different experimental conditions to evaluate its performances. The purpose of this device is to provide a new machine overheat apparatus which has many of the advantages of the overheat indicators and some added novel features. It comprises a temperature sensor situated within an engine of a machine which is adapted to transmit an output voltage directly proportional to the temperature within the engine of the vehicle user control over the temperature is provided using a potentiometer. System uses smoke sensor system that keeps measuring and report it through LCD display, Buzzer. The sensor interacts with microcontroller which process this data and transmit it over LCD display. By help of this model that uses GSM module, buzzer and display unit will allow to monitor heat level in different areas, and if system detects heat for that area is above allowed level then the value of temperature will have displayed at display unit section, information will be sent to the owner or the operator with alarm and SMS alert.

1.0                                                        INTRODUCTION

1.1                                                Background of the study

Machine Overheat detection with GSM project is used to detect the temperature of the devices which are overheated. This project is very useful in the industries or factories which have many big machines where the action must have taken place when the machines are overheated. In this system we use the digital sensor of temperature which is used to detect the temperature and after detecting the temperature it sends the signals towards the microcontrollers which are attached in this project. The microcontrollers which are attached in this computer on the data and then transfer the temperature reading and then this reading is displayed onto the screen. The display screen consists of the seven segments which are used to display the three numbers on the LED screen. This system consists of the different push buttons. These buttons are used to set the temperature whether it set high or it set low. When we set the buttons, it allows the user to do increment or do decrement in the temperature of the whole system. In this project we can use the 12 volts of transformer which is used to supply the power to the system. In this system we can set the specific temperature of the machine. If the temperature exceeds the given value which is given to it, the temperature sensor sends signals towards the microcontrollers and then microcontrollers shows message, or we use the buzzer in this system which produces the beep sound on exceeding the specific value of temperature which is given to the system. This proposed system is used to detect temperature of devices that are overheated. This project is very beneficial especially in places like factories or industries consisting of big machines where it is very necessary to take some action in case the machine is overheated. The system uses a digital temperature sensor to detect temperature and pass on the data to the microcontroller. The arduino microcontroller processes data and sends the temperature to be displayed on LCD screen. The display consists of LCD unit to display up to 3 numbers. It consists of potentiometer for setting the high and low temperatures. Adjusting the potentiometer allows user to increment and decrement the temperature of the system. The system uses 12V transformer to supply power to the system. We can set a limit to the temperature and in case if the system exceeds the temperature limit, an alarm rings to indicate that the system has exceeded the set temperature.

This project is very useful. It has many advantages in the industries and on many other places.

1.2      Problem statement

Modern manufacturing operations and other operating devices use many types of equipment that are subjected to loads that cause heating in portions of the machine or unit. Sometimes the heating occurs in electrically powered equipment, such as electric motors, welding transformers, and welding guns. The heating may also occur in equipment such as gear boxes and machining equipment that experience frictional loading. Often the equipment is used in circumstances that make maximum use of its design capabilities and may result in substantial heat generation within a heavily loaded, manufacturing unit. Further, the equipment may be expected to operate with minimal operator attention or oversight, but when an overheat is not detected in time it can lead to breakdown or failure of the machine.

Thus, there is a need for inexpensive and low energy-consuming devices that may be adapted to function autonomously as a temperature monitor, providing an overheat signal or over-temperature signal, for the environment of many different machines used in manufacturing or other operations.

There is a need for such devices to fit, non-obtrusively, on or in thermal contact with the equipment, or within the equipment, and to give a visible warning signal if, or when, some portion of the equipment reaches a temperature that indicates that it is overheating, which is likely to be harmful to its continued operation.

1.3      Aim and objectives of the Project

The main aim of this work is to design a device such as is used, for example, in manufacturing operations, each fitted-device serving to give notice of overheating of the machine to which it is attached or thermally connected the release of the visible overheat sign can be further used to initiate an audible warning signal and SMS alert to the user, and can also initiate a signal for preserving a record of the overheating event. The objectives of the study are:

1. To build the system prototype
2. To send an audible warning signal and SMS alert to the user whenever an engine temperature exceeds the predetermine level.

• To protect an engine from failure or breakdown

1.4      Scope of the study

The scope of this work covers building a device that is adapted for placement on (or in thermal contact with) a surface of an operating unit of equipment, machine, or the like, for raising a visible, SMS when the operating machine unit is experiencing overheating. The device was built around an arduino microntroller as the heart of the circuit, lm35 IC as the sensor and a GSM module. Overheating-detection device is shaped, or otherwise adapted, to be placed on a selected surface of the equipment, often a surface that is visible to someone near the equipment as it is being operated. The selected surface region of the equipment unit will serve as a useful sensing location if the unit experiences an overheating condition of operation. During operation of the equipment, heat will be transferred from the selected surface of the unit into a special material portion of the in-situ device. The special material is sometimes referred to in this specification as an “active” material or as a “smart” material. The material is characterized as active or smart because it is composed or adapted to experience a physical transformation when it is heated to a temperature range indicative of overheating in the equipment on which it is placed or in intimate thermal contact. This transformation of the active material is used to raise (or otherwise re-position) the tabular flag member to a position in which it is visible, or may otherwise give its notice of machine overheating. As will be more fully described in this specification, examples of suitable active materials include linear shapes of shape memory alloy compositions, sheets or other suitable shapes of shape memory polymers or other polymer compositions, and certain confined volumes or bodies of organic paraffin materials. As stated, the active material is selected, composed, or otherwise adapted to experience a useful physical transformation when it is heated by its contacting equipment unit to a temperature, or narrow temperature range, indicative of overheating within the machine that it

Advantages of Microcontroller based Overheat detector using Temperature sensor with Buzzer indication.

This project is easy to use.

1.6      Applications of the Project

Applications of Microcontroller based Overheat detector using Temperature sensor with GSM is that this project can be used in Industries, Companies and Home to monitor and stop High temperature condition resulting in loss of revenue and lives. Firefighting robot controlled using RF transmitter and RF receiver is a simple example electronics project, practical application of heat detector. The circuit consists of heat detector (lm35) that is connected microcontroller of the receiver block which is interfaced with robotic vehicle. Under normal room temperature, heat detector will not give any signal to the microcontroller and thus pump remains off. If once heat detector detects any considerable change, then it sends signal to the microcontroller. Microcontroller sends a signal to the pump through a relay to activate it and extinguish the fire (if any). Detector can be used in real time embedded systems based project firefighting robotic vehicle and temperature controller project.
