Green house is generally a building of small or large structures. The structure of the green house is made of walls and the translucent roof, with the capability of maintaining the planned climatic condition. It ensures the growth of plants that requires a specified level of soil moisture, sunlight, humidity and temperature. The green house systems available are human monitored systems that entail the continuous human visit causing distress to the worker and also decrease in the yield if the temperature and the humidity are not properly and regularly maintained. This paves way for the concept of the green house automation. The green house automation formed by the incorporation of the Internet of things and the embedded system addresses the problem faced in the green house and provides with the automated controlling and monitoring of the green house environment replacing the undeviating administration of the farmers. This paper also proposes the automation using internet of things in green house environment by using the Netduino 3 and employing the sensors for the sensing the moisture, temperature, sunlight and humidity, to enhance the production rate and minimize the discomfort caused to the farmers.

The Embedded System

This paper presents the possible new design paradigm that emerged during the author’s design of an embedded communication device for Croatian Navy. Prior to codesign techniques that emerged in 1990's the traditional embedded design methodology involved problem specification, separate hardware and software specification, integration, and the system test as the final step in the embedded device design. Such an approach can potentially lead to numerous iterations and can increase the cost of the development cycle because there are no guarantees that separately developed software will work well with separately designed hardware. Codesign techniques, on the other hand, delay the decision to which components of hardware or software will be used for embedded system until late stages of embedded design process. At the time of the invention of the codesign techniques this seemed as perfectly balanced approach between design of hardware and software spending about equal time in the design of both hardware and software components. However, since the 1990’s the design of embedded devices has changed; nowadays the most working hours are spent in the design of software while the design of hardware requires less working hours due to extensive choice of IC’s and supporting electronic circuits, and due to advancement of EDA software tools. In favor of the software-driven approach presented in this paper, it should be noted that nowadays, there is a large number of freely-available software components and libraries which, if properly utilized, greatly expedite the development of the software part of the embedded system design. Therefore, perhaps it is a suitable time for a new paradigm shift where the design of the hardware is completely dictated by the design of software, and the design of the hardware is simply the matter of selecting proper IC’s and other electronic circuitry that supports the software. In this paper, we present an example of the embedded design using this software-driven design strategy. By the end of this paper, it is shown that software-driven design not only allows the rapid prototyping of embedded devices, but it reduces the possibility of design errors, as well.

Client Side

Due to modern microcomputers and platforms based on microprocessors such as, for example, Raspberry Pi, Orange Pi, Nano Pi, Rock Pi, Banana Pi, Asus Tinker Board – the development of prototypes of em-bedded systems is possible in a «design» mode. The software part is implemented on the basis of operat-ing systems and standard technologies based on well-known programming languages such as C / C++, Python, C#, Java, etc. In such case the control channel for the embedded system can be either imple-mented via a web service separated by a communication channel or controlled independently. It is im-portant to understand that creating an embedded system on a standard platform is much more expensive than buying a ready-made mass-produced device with the same functionality. Therefore, it makes sense to use platforms like the Raspberry Pi mainly for individual artificial devices. If it is necessary to build a project of embedded systems and there is a problem with choosing a hardware platform for the client side, then currently there is a wide range of boards and solutions for building an efficient and inexpen-sive system using ready-made modules. The number of expansion cards and various sensors, video cam-eras, internet connection via Ethernet, Wi-Fi and Bluetooth provides a wide range of opportunities for building almost any solution based on this component base. The foundation can be made within a small budget, with minimal time spent, using large blocks and ready-made libraries for programming embed-ded systems. This article presents the results of research and development work on the creation of a software and hardware infrastructure of a terrestrial platform with the elements of artificial intelligence. Based on the actual results of the research, a deployment diagram and a component diagram of such an infrastructure have been constructed.

This paper explores the challenges and devised solutions for embedded development which arose during the COVID-19 pandemic. While software development, nowadays with modern tools and services such as git, virtual machines and commu-nication suits, is relatively una˙ected by resource location. That is not the case for firmware and embedded systems, which relies on physical hard-ware for design, development, and testing. To overcome the limitations of remote work and ob-structed access to actual hardware, two ideas were implemented and tested. First, based on inte-grated circuit emulation using QEMU to emulate an ARM core and custom software to facilitate communication with the embedded system. Sec-ond, remote programming and debugging over the internet with a dedicated computer system acting as a middle man between a development environ-ment and physical hardware using OpenOCD de-bugger.

In the current natural environment, due to the complexity of the background and the high similarity of the color between immature green tomatoes and the plant, the occlusion of the key organs (flower and fruit) by the leaves and stems will lead to low recognition rates and poor generalizations of the detection model. Therefore, an improved tomato organ detection method based on convolutional neural network (CNN) has been proposed in this paper. Based on the original Faster R-CNN algorithm, Resnet-50 with residual blocks was used to replace the traditional vgg16 feature extraction network, and a K-means clustering method was used to adjust more appropriate anchor sizes than manual setting, to improve detection accuracy. The test results showed that the mean average precision (mAP) was significantly improved compared with the traditional Faster R-CNN model. The training model can be transplanted to the embedded system, which lays a theoretical foundation for the development of a precise targeting pesticide application system and an automatic picking device.
