Design and development of quality control and power monitoring system for dairy shops.
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryRunning a dairy shop is labour-intensive. It requires a number of workers to accomplish backbreaking, repetitive, and monotonous physical tasks day and night, with low levels of motivation.Labor costs could reach a whopping 50% of the entire product cost. Into this comes automated milking machines as much-needed relief to boost production and profitability in dairy systems.Technology today allows dairy farms to automate much of the complex and repetitive tasks, using robots, and provide more control and speed over the production and processing of milk. One of the use cases of automation in the dairy industry is automatic milking systems , which replace the practice of milking by hand. They provide greater flexibility of milking times and frequency than conventional milking systems. Automated dairy systems can help us to deliver a diverse mix of consistently high-quality, safely produced products.As we have selected 'Automated dairy system with power control' after observing a lot of projects, because we have observed that automation is widely used in most of the companies for various processes. In today's generation it is needed in each field. Thus all the process needs a few operators to control automation. Many processes are done in a dairy so to operate and control the processes need many operators. Our aim is to reduce operators and to save time and money. The benefits of automated dairy (milking) systems are far-reaching. Cost-cutting in terms of less workforce is the biggest advantage, as it doesn’t require too many people to operate or monitor. The milking frequency can increase up to three times per day. On a typical day, it can reach 2.5 times per day.This will be achieved by automation and we have used STM32 and Esp32 with cloud.
The embedded based system allows users to know the quality regarding milk and As the milk is kept in containers in dairy shops , the expansion of bacteria will get increased which ends up in undesirable smell, style and harmful substances. Hence there is a necessity for a monitoring system to discover and determine the spoilage of milk and turn out into a healthy product.
In this proposed system, Microbial activity is determined using a gas sensor, high quality milk should have no salinity, so salinity of the milk is measured by using a salinity sensor and also level of the milk will be measured by using a level sensor. In addition to that, customers should have their own choice to enter in HMI for accessing the milk diaries.
Project ObjectivesThe basic aim of this project is to design and develop an automated milk device for power monitoring and quality control system that enable it’s user to monitor the total amount of milk present in the tank, it will enable the user to get the desired amount of dairy liquid on giving input and will stop the flow of it as soon as the desired amount is poured. Our project will be programmed in such a way that it will close the valve automatically as soon as the desired amount is filled and will upload data to an IoT cloud where the sent data will consist of date, liquid quantity (in Litres), price according to that day. Our project will also monitor the power which is drawn by the system and will also upload the daily power consumption by the system. This is how we will help dairy shops to innovate their shops by introducing this new product which will make so many tasks easy for them i.e. power monitoring, record keeping, flow control with less human involvement.The system in this project is new therefore, it will take time to develop trust in the Industry and its further implications. Similarly, it will also be a difficult phase to compete with big names such as PEL Siemens, Schneider Electric etc. Although we will make our project user friendly and cost effective.
In this embedded system, we aimed to present some aspects regarding milk quality and quantity estimation. So, in this proposed system each customer should have their own choice for accessing the milk quantity. High quality milk must have no salinity, so salinity of the milk is measured by using a salinity sensor for detecting adulteration of milk and level of the milk will be measured by using a level sensor for measuring the quantity of the milk. When the milk is stored for long, the microbial activity gets started which gives the milk a foul smell which can be detected using a gas sensor. In the existing system only the gas sensors are used for detection of early microbial activity which makes it useless when it comes to detection of adulteration of milk, our proposed system detects both aspects, adulteration as well as early microbial activity in milk.
Project Implementation MethodThe initial part is to design the hardware part of the project involving the tank with the innovated valve system that will be controlled using the microcontroller(STM23) interference with IoT clouds that will be working on sort of HMI in which the user will input the value that data will b store in backlog using thee IoT cloud and laer on the amount will be delivered to the user sing the weighing scale .All the data plus the power monitoring will be done through the sensor and actuators that will monitor the voltage and current level these all values will be stored on log through the controller.
We will make a IoT based solution for dairy shops to monitor the total amount of milk/dairy product in the tank, this system will give user the ability to take desired amount of dairy product on giving the input i.e. 1 litre, 2litres etc and as soon as the output amount becomes equal to amount (in litres) entered by user the dairy product will stop flowing automatically. This system will also monitor the power drawn by the system and also upload the daily datasheet of all the product transactions with its quantity, date, and total price on IoT based cloud.
We will use a Microcontroller STM32 which can drive by DC supply; the quality of the milk is maintained by using the smart sensors the temperature sensor helps in monitoring the temperature of the milk. The viscosity sensor measures the viscosity, the gas sensor is used to detect the odour of the milk, the milk level sensor is used to measure the quantity of milk, and the salinity sensor detects the salinity of the milk. The reader reads a card which consists of the customer details and the payment details, if the predefined customer makes the successful payment the motor will be switched on denoting the milk is filling. If there is an unknown entry or the insufficient payment the buzzer will be blown.
Benefits of the ProjectThe project is beneficial for industrial purposes as it is helping the local market by a simple device that All the data of the milk collection process is recorded digitally, eliminating the need of maintaining it manually in registers. Thus, it provides a smart, technological solution to cumbersome procedures. Digital recording also speeds up the milk collection process, allowing the collection of more milk in less time.This device will enable the user to interface directly by using HMI so it will be easier to do and thus an automatic record will be maintained.The power consumption of the system will be monitored by the device that will help user to serve money at a single device with multiple purpose. This device will help users to control the quality of milk by using multiple sensors for salinity ,gas pH and level of the product in the container will be monitored directly through the surface..
Technical Details of Final DeliverableThe final product of this project will be a device with multiple task performance ability that helps users to interface directly through HMI. The device will check the quality of milk including the PH, viscosity,salinity ,gas in the milk.it will keep record of the whole process on the back log using a cloud that will store daily sales,purchase and current and voltage consumption of the whole system.the backlog of all the thing utilised will be monitored through cloud and each and every usage of current and voltage will be checked and maintained
The device will reduce the labour work and wastage of food through any means as it will check the quality and each and every measurement will be according to the controller used.
