DESIGN OF INTELLIGENT SYSTEM FOR PROTECTION AND MONITORING COOLING SYSTEM OF MILLING MACHINE WITH AUTO NOTIFICATIONS AT UJANGE VILLAGE.

PROBLEM STATEMENT

It is Observed that, Overheating and air sucking of the milling machine due to the shortage of water and oil respectively resulting to failure and stacking of the milling machine to operate at UJANGE.Also, excess heating machine parts reduces the life span of machine and can cause high maintenance cost. The existing system of that village depends on human intervention to refill water in water tank hence it is not efficient and user friendly

MAIN OBJECTIVES

The main objective of this project is to design an intelligent system for protection and monitoring cooling system of milling machine with auto notifications at Ujange.

 SPECIFIC OBJECTIVE

i. To study the existing system for cooling system in milling machine 

ii. To design water detecting circuit

iii. To design the control circuit  

iv. To design the switching circuit

SIGNIFICANCE

i.   The milling machine is protected against failure or stacking due to overheating caused by lack of water.

ii.  The milling machine is also protected from  failure due to air sucking caused by shortage of oil

iii. It will increase the life span of machine 

iv.  It will avoid unnecessary cost for maintenance cause by damage of machine parts due to overheating 

EXPLANATION OF EXISTINGSYSTEM

The existing system at Ujange use manual way to monitor cooling system where by operator has to regular checkup the water tank if there is enough water, is there is no enough water in the water tank has to refill manually same applies to the oil tank the operator has to do regular check in the oil tank so that he/she can refill when oil run low. The existing system does not check the oil quality it involve the operator to check it after a certain period of time. Due human error this system is not doing well enough because sometimes it can happen the machine runs in absence of either water or oil which results in overheating of machine something which can eventually damage the machine parts. Damage of machine parts it can cause high maintenance cost, also it can reduce the life span of machine. Another problem is time wastage for refilling water manually in reserve tank and poor efficiency as it is difficult for human being to be active all of the time monitoring the water level in water tank and the oil quality. 

DISADVANTAGE OF EXISTING SYSTEM.

 i. The machine gets overheating due to lack of water causing   stacking of the machine.

 ii. The machine sucks air when there is no oil causing failure.

 iii. Poor lubrication when the oil quality degrades

 iv. It is not user friendly 

  v. It is not efficient.

EXPLANATION OF PROPOSED SYSTEM

The proposed system is intelligent system for protection and monitoring cooling system of milling machine with auto notifications is a system which protects the machine from damage or any other inconveniences when it is operating. This system will be monitoring presence of oil and water in their tanks as well as the oil quality automatically. Whenever shortage of water is detected by sensor, microcontroller will command the switching circuit to switch on the water pump and start refilling water from reserve tank to water tank automatically without human intervention, whenever water in both water tank and reverse tank is below the recommended level it will turn on the indicator to alert the operator so that can find out the alternative for refilling water in reserve tank otherwise the machine will be switched off automatically in order to protect it from overheating. On other hand when oil in its tank is below the recommend level it will turn on the indicator to alert the operator, when it is not refilled on time the machine will be switched off automatically in order to protect it from overheating due to shortage of oil. All are displayed through  Liquid crystal display whenever are below the recommended.

DISPLAY ANALYSIS

20x4  Liquid crystal display is chosen due to the following features.

1. Low power consumption
2. Inexpensive compared to other LCDs
3. Only few words are displayed, thus it meets 

ATmega328p is an 8-bit and 28 Pins AVR Microcontroller, manufactured by Microchip, follows RISC Architecture and has a flash type program memory of 32KB.

It has an EEPROM memory of 1KB and its SRAM memory is of 2KB.

It has 8 Pin for ADC operations, which all combines to form Port A ( PA0 –PA7) .It also has 3 built-in Timers, two of them are 8 Bit timers while the third one is 16-Bit Timer.

It operates ranging from 3.3V to 5.5V but normally we use 5V as a standard.
