Everything around us is getting smarter and changing. The change is taking step toward a better and smart future. The major role of engineering focus to play a pivotal role in bringing those changes to make a point-breaking understanding of the technologies around us in a better way. A smart home can make a smart city, likewise a smart industry can revolutionize the process for a smarter maintenance. It is a small step in making smart industries by reducing the complexity of wired communication with replaceable—connecting devices and cloud platform for analysis and control . This also solves the problem of complex hardware architecture by replacing structural complexity with logical devices and advanced communication devices.
This paper aims to deploy computing techniques in creating a barrier to integration, complexity, to provide more financial gains and energy savings. Sustainability of resources in many small- and medium-scale industries is a current dominant issue. Automated process is a very efficient and effective process on installing very-high-configured equipment, which is a possible constraint in small and medium industries. Consistent growth in market defines targets, but lack of resources has become a possible challenge in many ways.
A simple consideration of a mushroom harvesting plant, where the production process takes minimum of 14 weeks for the yield and most of the approach, is manual. A conveyor system would possibly reduce time of transporting yield; maintain the same environment and easy handling [2, 3]. But yet most of the process is manual and all the information is recorded by a person. This has a possible disadvantage of failure in certain conditions.
The problem persists in many other companies, where the process is dependent on manpower. To avoid problems of human error and to utilize all the manpower for a better production, this paper provides a brief insight of possible advantages of IoT in automation industry.
Initiating the process, identifying metal from nonmetal, handling the part as per requirement are the general insights briefed in this paper with real-time deployment. Usage of IoT concepts helps to monitor the process from any part of the world. One needs not to possibly be live at the moment to see the process. All the processes can be recorded, sorted, and are ready for analytics at an instance.
2 Internet of Things: A Case Study
The way of communication, life style, work culture, and ease of data extraction has changed with Internet. Connecting people bought revolution in once livelihood and next era of modernization is connecting various devices through Internet and cloud, by which smart and intelligent devices revolutionize once working methodology. A survey report stating the number of estimated connecting devices will be 50 billion at least by 2020 which are connected to cloud platform [4, 5]. A better and sophisticated way to connect with other devices is by machine-to-machine (M2M) applications. With IoT, the maximum allowance of physical devices connected to cloud platform would lead to mobile revolution. Comfort, safety, and efficiency are the driving factors for IoT, connecting physical objects to cloud Internet platform. The abbreviation IoT is not yet well defined; Cisco calls it Internet of Everything. Generally, it is Industrial Internet and IBM calls this as the same Internet. But all agree that IoT will make our physical systems much smarter.
2.1 Different Layers of IoT Protocols
2.2 Networking Protocols and Standards for IoT
IoT got a lot of importance from recent past from both academic researches an industrial approach. Due its vast application, support a lot of funding for research is encouraged. Lot of financial aid is being supported and spent to IoT-related technologies and on research, yet a lot of research is being expected in the following years [5, 6, 7].
Considering the protocols related to IoT which are operating at various layers in the networking stack, which includes: MAC—medium access control layer, network and session layer. Representing IoT, the standards and protocols were supported by Internet Engineering Task Force (IETF), IEEE—Institute of Electrical and Electronics Engineers, ITU—International Telecommunication Union (ITU), and other standard organizations. A consistent research of half decade proposed a lot of standards for current and future necessity.
2.3 IoT Ecosystem
Developing a successful IoT application is still not an easy task due to multiple challenges [10, 11]. These challenges include mobility, reliability, scalability, management, availability, interoperability, and security and privacy.
3 Basic Concept
3.1 Working Principle
A command from user will initiate the process; the part on the conveyor system is identified by a metal sensor integrated over the system. An ultrasonic sensor will identify the exact position of the part over conveyor and stop the sequence; every piece of working can be monitored by a custom-designed Webpage 1tuch.in.
4 Design and Implementation
Initial setup for the design is as follows: a metal sensor is interfaced to sense the metal objects or parts with better accuracy. MCU (Arduino Uno) is being used for automatic control of entire system which reduces the complexity of design and control. Entire input from sensor unit is provided to MCU for processing, the input from the sensor unit which senses the metal, the data is transmitted to user through Wi-Fi which is connected to cloud/Internet. Acceptance information is being monitored and maintained the server, which will send a message to the user, and the response from the user will decide the action to be performed by the robotic arm with respect to the status of metal sensor.
Later stages implementing the ultrasonic sensor for measuring exact location of part on conveyor reduced the complexity for robotic arm to take necessary action.
4.1 Programming Steps for Programming Arduino Uno Board
Connect Arduino Uno to USB port of computer.
Initialize the board by selecting type of board being used and also with virtual port assigned to the board in the tools menu.
An Arduino Uno sketch usually has five parts: declaring the variables; enabling the setup routine, which will initialize the variables and conditions to run the preliminary code; looping, is the place you add the main algorithm which will be executed repeatedly till an external reset is actively pressed or the sequence is terminated by the user; final section will be for other important functions to activate during the setup enablement and for loop routines.
To test the device, upload a preloaded program. This will ensure the device functioning.
Once after testing, the board is ready for any purpose deployment. Once disconnecting from computer and integrating it with proposed projects directly.
Once the program is executed and compiled the project is converted into hex format and can be downloaded into device.
- (vii)Thus, the project life cycle is accustomed with the project implementation (Fig. 8).
4.2 Processing Programming Environment
This is a tool to learn how to program using flexible software sketchbook and within the context of visual arts. This open-source tool is more compatible for integrating with external devices like Arduino Uno.
4.3 Real-Time Model
5 Results, Conclusion, and Future Scope
Through this approach, a lot of calibrations were recorded with few IoT protocols. Considering only one parameter like metal to provide results, being a repetitive process it needs better algorithms and advanced communication protocols to integrate more sensoric data into the cloud platform.
Among 15 iteration cycles, 2 cycles were out of the algorithm. This is a constraint to focus on. A general loop governing the system yields such a result. Further progress is achieved with control algorithms creating a feedback loop using PID tuning filter.
TCP protocol is being implemented for regular communication, with this algorithm, and by using open-source hardware equipment, the designed node could not resist the high-flow buffer rate and the timing function plays a vital role. Little iteration was satisfactory with a time lag of 3–4 s, while few took a time gap of above 10 s. This has a severe effect at the process and outcome. A server-to-server communication way is being implemented for further understanding. Considering packet ratio, durability, timing functions, the approach has given some satisfactory results. Despite this, a lot of research, implementation, and understanding is necessary.
Advanced protocols like MQTT have a benefit compared to TCP and UDP. Few other protocols should also be revised in this case.
This research review paper portrays the importance of IoT in manufacturing and assembly units, its current growth, protocols defining the rules, and further expansion in large scale.
