Factory Worker Alcohol Detector with Automatic Machine Shutdown System

Factory Worker Alcohol Detector with Automatic Machine Shutdown System Factory worker alcohol detector with automatic machine shutdown system is a system, that checks the worker condition constantly, either he is in drunk or normal condition if he is in drunk condition then also check the range of this drunk value if it is above the permissible range then shutdown the machine automatically with sending alert message at authorized mobile no. If we see in our industry side, then there are so many machines which are so much costly and their operating system is also so much complicated. For operating this complicated system, the worker should be in medically or mentally fit condition, otherwise a one mistake leads to a serious consequence, such as in the form of life or business loss. If anyone or factory worker take a drunk then, it directly effects on his mental condition and in this condition if he operates the machine then he would damage the machine or loss of the life. For escaping this life or business loss here we have designed a system that is called a factory worker alcohol detector with automatic machine shutdown system with the help of pic microcontroller 18F452, alcohol sensor, GSM modem, LCD display and motor. This system shutdown the machine automatically after detecting the worker drunk condition. Block Diagram of Factory Worker Alcohol Detector with Automatic Machine Shutdown System: Here is the block diagram of this factory worker alcohol detector with automatic machine shutdown system with all essential components. Figure 1 Block Diagram of Factory Worker Alcohol Detector with Automatic Machine Shutdown System Components List with Detail of Factory Worker Alcohol Detector with Automatic Machine Shutdown System: Transformer: In this factory worker alcohol detector with automatic machine shutdown system, transformer is used for steps down AC voltages. It steps down the 220V ac to 12V ac and works on the principle of mutual induction. Bridge Rectifier: In this factory worker alcohol detector with automatic machine shutdown system, bridge rectifier is used for converting the ac voltages into dc voltages and consists of four diodes. Blocking Diode: In this automatic system, the blocking diode is used for blocking the reverse polarity current in other words it provides the protection of transformer. Voltage Regulator: In this factory worker alcohol detector with automatic machine shutdown system, voltage regulator is used for regulating the 12V dc into 5V dc. Here for regulating dc voltages LM 7805 IC have been used. LCD Display: In this factory worker alcohol detector with automatic machine shutdown system, LCD display is used for displaying the alerting mode of this system. It is 16 pins LCD display and is interfaced with microcontroller. It is powered up with 5V dc supply. Max232: In this factory worker alcohol detector with automatic machine shutdown system, the max 232 IC is only used for serial communication between microcontroller and GSM modem. It 16pins dual channel integrated circuit IC and is powered up with 5V dc supply. GSM Modem: In this factory worker alcohol detector with automatic machine shutdown system, the GSM modem is used for communication purposes between the user mobile phone and microcontroller. It is wireless base modem, accepts the sim card and works on the principle of used mobile phone subscription. Microcontroller: In this factory worker alcohol detector with automatic machine shutdown system, microcontroller pic18F452 is used for the intelligent control of this system. It is 40 pins integrated circuit microcontroller, programmed in C language with the help of mikro/c software and is powered up with 5V dc supply. Here it is interfaced with GSM modem, alcohol sensor and output motor. Buzzer: In this system, the buzzer is only used for releasing the sound during the alert mode on this system. Alcohol Sensor: In this factory worker alcohol detector with automatic machine shutdown system, the alcohol sensor is used for sensing the concentration of alcohol through human breathing. It is a 5 device and for its operation pin 3 is connected to VCC, pin 2 is connected to ground and pin 2 is connected to output. This sensor has very good sensitivity and fast response for alcohol detection. Motor: The working of this system is checked by connecting the dc motor at output side. Working Principle of Factory Worker Alcohol Detector with Automatic Machine Shutdown System: This factory worker alcohol detector with automatic machine shutdown system works on the principle of alcohol detection. Alcohol is detecting through the alcohol sensor, when this sensor senses the alcohol then its resistance is changed as per the concentration of alcohol, means when alcohol concentration is high then its resistance would be low and when alcohol concentration is low then its resistance would be high. Here for demonstration purposes dc motor has been used. When any drunk person takes the breath in front of alcohol sensor then alcohol sensor senses this breath and check the concentration level of alcohol if the concentration level is high then permissible level then it gives the logic high signal to microcontroller. After receiving the logic high signal, microcontroller goes into the alerting mode. In alerting mode, it turns on the buzzer for giving warning intimation and display this alert mode on LCD display. In this condition, microcontroller also gives the logic low signal to turn off the motor and gives the intimation message at authorized mobile phone through the GSM modem. So, this is the main working principle of the automatic system. Applications and Advantages of Factory Worker Alcohol Detector with Automatic Machine Shutdown System: 1. This factory worker alcohol detector with automatic machine shutdown system could be used in industries for saving human life. 2. By using this system machine could shutdown automatically when any drunk person is worked. 3. By using this system authorized person can easily know the worker mentally condition through the alerting message. 4. By using this system factory owners can easily escape from human and business loss. 5. This system is more precise, easy to install and has less installation, maintenance cost as compared to the other systems.
