There are currently many business areas struggling, but the Internet of Things and Industrial Internet of Things are not included in this pressure range. If you are concerned about the risks of COVID 19 and the distance between you and your colleagues, then you don’t have to worry about the benefits of the Internet of Things and IoT.
The advantage of the Internet of Things and the Internet of Things lies in the ability to obtain data from a long distance. We now have a greater way to connect our information at greater distances. In the current business trend, we are trying to become more creative. This means we adopt past systems and work hard to adapt them to our rapidly changing information needs.
A year ago, manufacturers were still considering how to weave IIoT into their information structure and existing IT systems. Fast forward to the present, we are adapting to Zoom meetings, working at home, and need to get answers. We used to walk on the factory floor or run a report in the office, but now we need to complete it at home.
Access is one of the big problems. How do we safely allow remote access to the server, and who can gain access to what system? This may be a difficult situation, because it is likely that the content that a person thinks they need to access may not be what the IT department and supervisor deem necessary.
You need to determine who needs what and when. Can they publicly access the Internet of Things information that is input to the reporting software or processor? Can you use a firewall to lock it outside? It is like a safe in a movie. Once locked, can it be opened the next morning? Once you Once you have determined who is authorized and needs this information, you can view the next stage. How to proceed?
How do users need this information? Let’s use a simple example of a sensor to track machines that are running or not. Once the sensor inputs the information to the accumulation device or controls it through the gateway, it will be filled and the information pushed to the cloud. Now, the software that reads the sensor time will put it in a register or location, and your other cloud programs will extract information from it. You may have an OEE program that uses this information to generate reports on OEE or efficiency. This is an advanced report that can combine this information with downtime information used by the maintenance department for preventive maintenance.
Uptime may be combined with work data to help managers in production determine whether they can meet demand, or to let them know that they will have to work overtime.
The above example is the department or person using this information. However, there are many programs that also need to extract this information. ERP (Enterprise Resource Planning) and MRP (Material Requirements Planning) systems, these systems will extract the same information and registration data to determine whether the manufacturer has sufficient supply of raw materials and whether the work in process can be completed.
Other programs, such as maintenance programs that use the number of running hours as a parameter to plan preventive care, also need to use these registers. Sharing data with people and programs is a very important part of the Internet of Things.
We know that accessibility and sharing are critical to the value of the Internet of Things, but what else? Feedback. Once we receive the information, we need to obtain the data and adjust the parameters. Many sensors today are tunable, and their sensitivity curves can be adjusted and calibrated according to the environment and even chemical composition. Many times, we think of the sensors and actuators that we are most familiar with, but there are many types that can monitor chemicals, gases, and locations. Some of these sensors require manual adjustment, or in many current sensors, there is an electronic adjustment. Feedback gives you better control over the accuracy of the sensor and makes it more sensitive.
The feedback also provides information to the smart controller, which is able to obtain data profiles and customize the sensor for the job or application. Many sensors are now using a combined approach. Using an optical sensor, coupled with an accelerometer, can provide a large range of motion to track position 1. Other sensors use depth, optical, and acoustic sensors to work in sync to input Microsoft computers using their Kinect system.
Programming the sensors and tracking their functions will give you a better result. The details of each sensor can be modified, the status of the sensor can be tracked, and compared with historical benchmarks.
One problem with sensors is that the closer you set the conversion distance, the more likely you are to receive errors such as switches or sensor bounces. This manifests itself as multiple openings and closings of the sensor. The intelligent system provides a solution by ignoring the transition that occurred near the first transition or using other measures to move the transition point to a more stable area.
In the field of IoT, an often overlooked solution is to look at the sensor’s actuator. In many cases, the switch arm or flag of the proximity switch may not be optimally set. Perhaps using a different switch arm with a different range of motion or one using a larger actuation point provides better performance.
Smart sensors use on-site processing, allowing the sensor to process on-site and only transmit “clean” information. This means that it is processed and attenuated to an appropriate level, and has a certain degree of safety and field wiring protection2. Many softwares are now integrated in a single software package for monitoring, communication or gateway, voltage and fault monitoring, and backup.
With more and more requirements for these sensors to be wireless and installable in other locations, the requirements for performance are also increasing. Failure is not an option, planning must be part of your IoT solution for all foreseeable problems, including signal outages and power outages. You need to develop a plan to process this sensor data in the event of a failure.
If you think about self-driving cars and their sensors. The more we rely on sensors and the Internet of Things, the more reliable it must be when lives are threatened. We have seen some failures ended in accidents, so we must work hard to optimize the performance of the sensor.
All parts of the Internet of Things are growing, and all parts must be improved to meet demand. Sensor performance, zero failure rate, gateways, communications and cloud infrastructure, as well as the speed and processing of upgrading all our software and programs.
In our future Jason world, everything must be dynamic and flexible to meet technological challenges. In manufacturing optimization, we discuss the fact that the strength of a chain is only its weakest link. The Internet of Things is working hard at all stages to avoid becoming the weakest link. Sensors are being improved to reduce energy consumption so that they can be restarted in a longer period of time. The redundant system is backing up data. While using better communication protocols, gateways are becoming more secure and faster. The speed of 5G is just around the corner, and our program is also being redesigned to speed up processing.
