Single board computers are those little circuit boards with the necessary components to be used as a digital computer and ideal for an outsourced IT specialist. They are not commonly seen as they are and that is the reason why most of us can’t recognize them even if we have one in front of us. However, a lot of people have used single board computers because they are often embedded in gadgets like mobile phones, facsimile machines, GPS and other computer technological products.

Single board computer is what a printed circuit board with memory, a processor, input – output and a digital clock is called. Single board computers (otherwise known as SBCs) look a lot like the motherboard inside an ordinary personal computer but with a small design.

Because they are really small, they are also known as embedded computers. SBCs may come in different sizes, too. In fact, they are used from aero planes to sky rockets. In a more general sense, they can be present in toys or highly technological shoes. It is easy to assume that everyone has used single board computers without realizing that they exist.

Nowadays, smaller versions of computers are becoming very common. While they can accommodate full versions of operating system like Windows XP, SBCs have their own internal operating systems which don’t occupy much space. It is a fact that simpler operating systems mean not costing a lot. Without affecting processor performance, input/output, capability to store some files and its wireless connection, single board computers can do the basic functions of a personal computer.

The Good and Bad about Single Board Computers

Like any other products, SBCs have two sides, too. The decision to whether or not to employ the technology of single board computers is influence by how important the application is and how much it costs.

Below are the positive factors to consider:

1. The high technological advancement nowadays have improved the capabilities of single board computers as they become smaller and less costly.
2. Internet access using the SBCs has been made possible with the use of Wireless technology.
3. Because of it is now available in the competitive market, better functions and variety of single board computers are also made available to the users.
4. Highly developed computer technology presents dependability for industrial producers and the quality of their products using SBC’s.

On the other hand, employing SBCs may not be cheap or reasonable when incorporated with products of high volume and other applications. Also, there are some of these applications that need made to order sizes. Another possibility is that the input/output of certain devices are not compatible with single board computers.

Despite these possibilities, though. A lot of companies opt to use SBCs in the production of their high end devices rather than make their customized industrial single board computers, which is why a lot of organizations use a managed services provider to maintain them.

QT demo application

Qt has always been available through a commercial license which allows the expansion of proprietary purposes without any restriction on licensing. In addition, Qt has been steadily made open through an increasing number of other free licenses. Currently, Qt is accessible under the General Public License (GNU); this provision makes it available for utilization for both free software and proprietary. Before the 1.45 version, the source code used for Qt was published under free Qt license. This was not really viewed as amenable with the free software description of the Free Software Foundation and neither by the Open Source principle as described by the Open Source Initiative. The reason behind this was that it did not allow the distribution of other modified versions.
In 1998, many controversies broke out when it was acknowledged that KDE’s  KDE software compilation would undoubtedly become the leading desktop setting especially for Linux. Owing to the fact that it was founded on a Qt basis, many professionals who took part in the free software movement became apprehensive that an imperative component of one of a leading operating system would become proprietary.
Along with the release of the 2.0 version of the toolbox, the license was transformed to the QPL (Q Public License). QPL was a free software license but it was considered incompatible with GPL by the Free Software Foundation. Trolltech and KDE then sought out many compromises which would imply that Qt will not be regarded by any license more restrictive than QPL, even in the case Trolltech goes bankrupt. This major issue led to the invention of the free Qt foundation by KDE.

Since this fast system enables transmission in the form of voice and other data as well it has wide implications. Since most forms of communication today require separate hard wiring it is convenient to use PLC which can employ the pre-existing power cables within the house. Since the power in these cables is AC (alternating Current), it can be employed for various bidirectional modes of communication as well.
Such a communication system can be used for the monitoring and also the controlling of various fundamental functions like energy management, security, and safety control applications at homes, factories, offices, aircraft etc. The Transmission companies use this type of transmission to synchronise the operations in various substations and to monitor the power supply at the consumer end. PLC systems include a transmitter unit competent of sending (transmitting) communication signals over the Power line signal and also have a receiver unit at the receiving end which separates the communication signal and the power signal.
The transmitter generates modulated RF signal at the sending end this signal is then demodulated at the receiving end. A power line communication modem is used to convert digital data from an information processing unit like a computer to analog data; these modems play a crucial role by helping the sending and receiving units to communicate with one another.
Like any modern technology the PLC system also suffers from various constraints, the technology is still not sufficiently advanced to take advantage of all the benefits that it has promised. Also since the PLC network is a electrical supply network and telecommunications network it comes under certain jurisdictions and legal frameworks. But since the technology is new there are not enough guidelines in place, for its proper running and installation. Interference issues are also a major concern that is since the signal is over lapping with lower frequency power signal; there is always an issue of improper decoding. The power wiring system was formerly intended for the transmission of Power, the power wire circuit usually has limited ability when it comes to carrying higher frequencies in which the data signals are encoded.

Modbus is a communication protocol which is used with programmable logic controllers. This communication protocol was published by a firm named Modicon in 1979. It has now become the most de facto standard protocol in the industry. Modbus is now very commonly used as a means to connect the industrial electronic devices. This protocol is very easily available as it is very extensively used. There are certain important reasons for the use of Modbus rather than use of other communication protocol. These are as follows:

1.This protocol is published openly and is royalty free.
2.It is an easiest way to setup an industrial network.
3.This protocol moves raw bits without any restrictions.

modbus webserver

Modbus can be used for various communications. It can be used for communication between devices which are connected to a particular network. For example, a system measuring the speed of the wind will transmits the data collected to a computer for records. Modbus as a communication protocol is used as a connection between the main computers and it is done with the help of Remote terminal unit (RTU) and data acquisitions (SCADA) systems.

There exist many editions of the Modbus. Various Modbus versions are used for Ethernet and also for the serial port. It is also used for the networks which support the IP, i.e. the internet protocol. Many of the Modbus devices commune with the help of a serial EIA-485 physical layer. Various versions of Modbus are as follows:

1. Modbus RTU – it is used for serial communications. This version of Modbus is normally implemented for use in communication.
2. Modbus ASCII – It is as a serial communication and the message transmitted are framed by a colon and a trailing new line.
3. Modbus TCP – this version is used for the communication between TCP networks.

The function calls and data model are same for these versions. The only difference between them is that the encapsulation varies for all. And also the frame formats varies for each of them.

Every device which communicates uses Modbus with a particular address. A Modbus command is used in various networks. This command has the particular device address and that device will only act on this command. All these command have the checking information and it make sure that the message comes undamaged. There is also a Modbus member organisation which can be joined by the large and small suppliers, system developers etc.

PIR sensor

PIR or the Passive Infrared sensor is an electronic device which is used to measure infrared light radiating from a body in its field of view. The sensors are known as Passive since they do not have an in built IR source like active sensors and detect the natural radiation of the body.

All objects have a certain body temperature and at any specific temperature there is a certain radiation that the body emits, this is called the Black Body Radiation phenomenon. The infrared radiation is undetectable to the human eye but can be detected by a PIR sensor. These sensors are commonly used as motion detector that is whenever a different body of different temperature passes from ahead of it, there is an apparent change in the infrared frequency detected due to different temperature of each body. This application is widely used in security equipments and other photo sensing equipment. The PIR sensors are very often paired with other devices to increase their range to encompass even human body sensors.

The PIR sensor is designed such that the light enters through the front of the sensor, which is known as the sensor face. This sensor face usually is made up of smaller sensor components which basically consist of pyroelectric materials in the form of thin films. These thin films may be made of Caesium nitrate or cobalt phthalocyanine and since these materials are pyroelectric they convert the light energy falling on them into small electrical signals. The IR sensor is contained within a fully sealed metal box so as to improve immunity towards noise, humidity, temperature and other effects. The window is the face, which is always made of IR-transmissive substances and is typically covered with silicon which is not only cheap but keeps the sensing element protected. At the rear of the window the balanced sensors are situated.

The device usually has 2 sensors connected to a differential amplifier so that useless signals are cancelled out and only valid inputs are detected. Though the range of PIR sensors is typically up to few 10s of feet but with some modifications, larger detectors using mirrors can sense changes in infrared signals up to a hundred feet away.

These sensors are often used to make other devices as well like PIR based remote thermometers; here a non differential PIR output is used. As the temperature of the body increases the radiation frequency changes and the sensor is able to detect that and a simple circuit attached to the output if properly calibrated can easily read the body’s temperature. In modern robotics such sensors are often installed in autonomous bots for motion sensing and path detection like in the case of line followers.

T-engine hardware

T-Engine is project that standardize the hardware part of development board (not the standardization of main processor).
This project is well-known amongst the processor manufacturer company in Japan. You can buy T-Engine development kit directly from Japanese
microprocessor manufacturers such as Renesas Technology or from electronics company like Personal Media Corp.I list websites where you can
find T-Engine development board to buy as below…

1. T-Engine4u (Personal Media Company)
2. T-Engine forum
3. T-Engine development kit from Yokogawa

T-Engine also has 3 subtypes. They are micro T-Engine, nano T-Engine and pico T-Engine.
Nano T-Engine is small size embedded platform (smaller that micro T-Engine). Its size is not bigger that the coin-size (view applications of nano T-Engine
and its development board here). Pico T-Engine is the smallest platform. It’s generally used for developing small device like switch, sensor or lighting equipment.
It can be used as the sensor node in wireless sensor network application too. If you want to know more about pico T-Engine , please visit this page.

Nowadays, there are various T-Engine development kits on the embedded system market. The difference between each one is the hardware
assembled to be the dvelopment kits. However , when you buy T-Engine board , it usually come along with Software Development Kit such as
Operating System , Driver for the peripheral devices , compiler , toolchains and extension of standard T-Kernel such as Virtual Memory module ,
Process Support Unit and File System , etc. Now , let talk about T-Kernel.

T-Kernel is the kernel for T-Engine platform. It’s one of the real-time operation system that was released by T-Engine forum.
T-Kernel only implement core source code of the kernel that can be commonly used in any T-Engine hardware platform.

It doesn’t include the drivers for specific hardware but it has only one sample driver source code you can use as the reference to make your own driver.

You can download T-Kernel source code directly from T-Engine forum (you need to subscribe to the source code or specification that you want to download).
The document that describe T-Kernel Specification is also available in English too.
However , the implementation guideine for porting T-Kernel to some processor (such as SH7751, VR5500, SH7727 , etc.)
is not written in English (it only availible in Japanese so you need to translate them by yourself ). The objective of T-Kernel is to provide software standard
for T-Engine platform. It also has the subsidiary called “micro T-Kernel or μT-Kernel”. T-Kernel is suitable for large embedded system that has 32-bit main processor
and it can be used in the system that has MMU (memory management unit) while μT-Kernel is proper to use in smaller embedded system like 16-bit CPU system
that has small amount of RAM and ROM and was designed to support the CPU that don’t have MMU.
On the other hand , we can said that μT-Kernel is small version of T-Kernel that cut off some unnecessary functions that will become an overhead in small system.
It has been optimized for efficiency and gain the best performance when using it on small embedded system.
