Everything began when a group of electrical and computer experts decided to transform the traditional structure of the building’s electricity. It was time for automation with all its advanced dimensions to enter the building and bring a new soul to the dead bodies of houses. The exact prediction IBM acknowledged at next Five in Five meetings a few years ago, and in an official article, predicted that one of the five phenomena that will change the world over the next five years is the smart house phenomenon. Founders of M & H were looking for a system for many and long meetings to enter the new world. At the same time, a number of European and American companies had achieved similar products, offering them as smart home appliances or larger in the form of BMS. The easiest way is to check these products and choose the best ones, and in the next step, obtain representation from the foreign manufacturer. Not spending too much, and not having to create a large structure for the intelligent system, were points that could not be passed.
The research was started and all the brands were checked one by one, but the more time it took, the results were more disappointing. The research method should be changed.
Regardless of what services are available in the world, the expectations of the indigenous industry in Iran should be explored. This time, M & H found itself in the position of builders and consumers of buildings, and in his view, identified the features of an ideal smart home system. Given the new technology in the building, the need to pay attention to beliefs, the degree of acceptance of changes by consumers, and a word of respect for customer taboo work. The customer was accustomed to turning the lights on with a regular electric switch, and resisted turning the keys into equipment that had not yet quit their test. The high price of housing and the difficulty of providing it to the buyer reduced the risk of taking risks in this area and the builder was afraid of selling homes with difficulty. So the first essential feature in the dreamy home, which M & H was looking for, was to maintain the traditional structure of electricity along with the provision of modern capabilities. With this in mind, the research circle was even more restricted.
The use of the X10 prototype was at the peak of the day due to the feature that could be provided on traditional wiring. But due to the high noise and difficulty of filtering it, especially in houses with more than one phase, it could not be a good option. The presence of noise sources such as televisions or wireless devices could produce virtual or ON signals. Noise filtering, which is installed on most computers or modems, could help keep these noises from X10 signals, but Noise filters that were not designed for the X10 could themselves absorb X10 signals. Later on, even the newer generation X10, known as the Power Line Carrier, still did not provide 100% accuracy.
At a later stage, the integration of the Knx protocol, which is a network communication protocol, seemed to provide traditional semi-intelligent mode in the building. Some smart keys and some others are common with the sockets. But this half-design was not approved by the builders due to the disassembly of keys and sockets and was a weakness. The full use of the knx smart keys was also not approved for the complete disturbance of the traditional wiring structure.
There were also other products on the market that replaced electric keys with full wiring. But these equipment did not provide the consumer, especially the manufacturers. The manufacturer was committed to the house he had built, and in case of the slightest failure in these keys, due to the lack of adequate and reliable services in the market, the buyers were found liable. The claims of the manufacturers of these types of keys were that in the event of a malfunction and a lack of sufficient services, these keys can easily be replaced with ordinary electric keys, but this does not return the water to the atmosphere and the brand is a good builder. It was because he had sold the house smartly to the customer. Meanwhile, the bankruptcy or failure to provide products of some of these companies to Iran was made more difficult by economic sanctions. Later, large companies like the French Lecce joined the crowd, and the makers who used the company’s products had unforeseen challenges in providing customer service.
Along with these reviews, there were suggestions on the use of wireless equipment around the corner and encouraged the group to investigate the issue. But the results of the survey were also not satisfactory. Because of the capabilities such as the announcement of theft, fire alert and gas leakage, it was one of the important capabilities that the group deemed necessary to be in the building, putting away these features in the wireless technology would eliminate any kind of assurance. win. Even if the product was presented, only reasonable control of the lights was made by the manufacturers. In the event of a potential problem, home lighting was disrupted, and this alone was enough to reject the new offer. Even more advanced devices such as WiFi modems were subject to intermittent power failure. However, there is still a problem with the use of these equipment for networking between computers, and the need for sufficient technical knowledge to make network settings is essential for a domestic consumer. Even looking at the technologies that came later, like Zigbee, despite the connectivity of more than 64,000 devices with each other, and a data rate of 250 kilobytes per second, which is a better alternative to Bluetooth, is still available for use in an ideal smart home, Not sure In general, all wireless equipment is 100% uncertain.
Reviews one after the other yielded a negative result and there was still no system that could meet the constructive expectation of maintaining the traditional structure of electricity and providing day-to-day capabilities on this traditional platform. This disappointment was a turning point in the emergence of an idea. The idea came after a week-long silent, with fear and shiver from a member of the group. No one seemed to have a better idea, and apparently the only way it did, except for defeat, was the same; production. The word that all members of the band liked, but in spite of the beautiful and ingenious association that the word originated from the birth of a new phenomenon, it was necessary to hope for an operational method. The overall structure of the design was formed little by little, and the result was that a central and powerful processor and, of course, a trusted computer as the heart of the system, would create a central control for the production of such a product. Power Distribution in the traditional way but from a smart power board with a processor.
Identifying the essential features of this processor was the next step. Creating an electronic board using a microcontroller of any kind was not logical and did not provide the desired quality for every reason, and more research was conducted every day using a market controller and programmable controller, that is, the same Programmable Controller This processor should be of sufficient frequency and, if removed from the market, simply replaced by another type. The lack of an obstacle in connecting a variety of sensors to it and the possibility of adding inputs or outputs of IO and Analog were other features expected by the group. On the other hand, the processor in a smart home should have the ability to control and display through a touch screen, which should be easily replaced in the future. The other feature that the group thought was to maintain this structure for future versions and should not have to change the basis of product upgrades because of the difficulty of providing services to previous customers. Even previous customers to upgrade The product itself should not bear the cost of replacing parts, and the structure should be designed in such a way that new features were introduced by adding new components. A topic that has come about in the coming years, such as the ability to control the smart home by tablet and mobile. Despite the fact that the system was enhanced and enjoyable, these features were not considered as the main frame of the device, and by eliminating them, the system still shines at peak performance. Eventually, this time, the research came to an end and, after a long time, the fatigue of the members went out. The processor that was introduced as the centerpiece of this system was a product that, while having an incredible diversity worldwide, could be replaced by all sorts of its own, and after 12 years of global baccalaureate at the International Electrotechnical Commission, the Brief Description of the International Electrotechnical Commission IEC called it in 1990, its final standards were closed and no producer had the right to change it. This decision was taken to create security in the industry, so that a manufacturer who uses this controller for his own devices in his factory, in the event of a breakdown in the years to come, could replace it with another type, and the plant would tolerate losses.
So, the group decided to build smart boards using the Programmable Logic Controller, which is briefly called PLC and is a familiar and confident name in the world’s industry. The design and firm structure of the product was so reliable that in the following years, many people copied this product. The unique design of the device, in keeping with the traditional structure of the electric power, made it easy to integrate traditional power systems in the event of an incident such as breaking a monitor or connecting power to home appliances. This will multiply the attractiveness of the product and there is no need to turn off the home lights before reaching the after-sales service. Ideally, with increasing day-to-day quality and quantity of capabilities by the manufacturing company, it became a fanatical product. A product that was created by the efforts of a dedicated expert group of experienced experts to enter the realm of the construction industry; the smart home of M & H has been a product that, by maintaining its customers’ consistent satisfaction, has been able to create the most powerful and diverse day of smart home in the country, and not only from Its makers and consumers, as well as from all the world’s top concerns. M & H is very pleased that it is a product of Iranian origin that is highly researched by its customers, but ultimately it always takes pride of choice on the part of its customers on the basis of its merit, and this is a golden brand that is trusted by M & H’s high-end customers. The role is closed. Now, after about 10 years of grace and thanks to friends and customers who helped us to get to this position, since then, we have become one of the creator of more dedicated service to our customers.
