Since the introduction of the smart city, it has received the attention of the general public. Now the smart city project has been launched in various regions, and the results are also very happy. However, wisdom is too hot, and now they are beginning to move to the countryside, so that urban and rural areas can have a real wisdom. This wave of wisdom will become an important opportunity to narrow the gap between urban and rural areas and effectively help solve the three rural issues.
The construction of smart countryside should guarantee the safety of farmers' lives and property, vigorously optimize the way farmers live their lives, and improve the quality of life of farmers as a never-ending pursuit.
The wave of intelligent construction flocks to the rural Internet of Things to help solve the three rural issues
The rise of Internet of Things technology has not been long. In general, the introduction and development of different regions are still on the same starting line. Nowadays, the construction of smart cities has already spread throughout the country, and the corresponding layout of the countryside has been followed up in time. This wave of wisdom will become an important opportunity to narrow the gap between urban and rural areas and effectively help solve the three rural issues.
The construction of a smart countryside should first guarantee the safety of farmers' lives and property. Unlike cities, the geographical environment in rural areas is often more complex and diverse. There are hidden dangers of various natural disasters in mountainous areas, forest areas, waters and other areas. It is necessary for villagers to maintain vigilance and prevent them in time.
Traditional manual monitoring methods are mostly inefficient and insufficient to cope with unexpected situations. And deploying the right security IoT can be accurate and fast in terms of forecasting, monitoring and alerting. In 2014, Hubei Province launched the “Village Village†rural intelligent broadcasting network project. By implanting smart chips for the broadcasting horns in the village and using mobile Internet of Things technology, a timely and effective disaster early warning system was constructed. In the event of a disaster, an authorized person can issue an alarm directly via a mobile phone, the Internet, etc., regardless of time and location.
Second, the construction of smart rural areas needs to vigorously optimize the way farmers earn a living. Crop cultivation and livestock rearing are the main economic sources for farmers. At present, the Internet of Things system dedicated to planting, aquaculture and animal husbandry has been implemented. Some new applications in rural areas in China have begun to introduce labor costs and improve product quality.
However, what the Internet of Things can do is not limited to this. The rise of rural e-commerce is allowing farmers as producers to take into account the role of operators and thus gain more profits. The Internet of Things can be a good medium for buyers and farmers to talk about business. Compared with a single picture, text and other information, real-time product production images, specific product-related data are more attractive to buyers, and this is what the Internet of Things can provide. In addition, in recent years, new projects such as crops and livestock adoption have emerged in rural tourism. If the Internet of Things enables the adopters to remotely grasp the growth of animals and plants at any time, it will undoubtedly attract more consumers to participate in the experience.
Finally, improving the quality of life of farmers should be a never-ending pursuit of smart rural construction. Objectively speaking, it is difficult to balance the spatial distribution of medical care, education, culture, entertainment and other resources in urban and rural areas, and the city will occupy a dominant position for a long time. However, these resources are equally important to the lives of the rural population.
The Internet of Things can greatly promote the sharing of urban resources in this kind of social resources, so that the distance in space is no longer a problem. Telemedicine, distance learning, digital libraries, etc. are maturing solutions. The city's high-quality resources are directly used by the rural population through the Internet of Things, and farmers do not have to travel long distances in order to seek medical advice or study. Although this is not as eye-catching as the construction of high-rise buildings, it has injected strong soft power into the urbanization process.
To realize the various ideas of smart rural construction, the first step is to complete the coverage of the vast rural areas by the Internet of Things. In addition to the three major operators actively preparing for the battle, the radio and television also took action in May this year, which will promote the super Wi-Fi rural Internet of Things to the whole country. It is believed that with the improvement of the basic network, various applications of the Internet of Things in rural areas will soon be promoted. The construction of smart villages will go hand in hand with the construction of smart cities and create a smart future that will benefit the entire population.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
In addition to SCSI, IDE is also a very common interface. From the point of view of ease of use, IDE is more suitable for ordinary users. In addition, personal computer users not only need to configure a few peripherals, but also do not require high speed. Therefore, it is more appropriate to choose IDE interface. In addition, IDE also has the characteristics of high performance price ratio and wide application. Although the SCSI interface has many incomparable characteristics, the price of the interface and its peripherals is too expensive to be borne by ordinary users, which determines the limitation of its actual use range.
1. The working mode of IDE requires the whole process participation of CPU. When the CPU reads and writes data, it can't perform other operations. In this case, in the multitask operating system of Windows 95 / NT, the system reaction will be greatly slowed down. The SCSI interface controls the data reading and writing operation completely through the independent high-speed SCSI card, so the CPU does not have to waste time to wait, which obviously can improve the overall performance of the system. However, IDE interface has also made great improvements to improve this problem. DMA mode can be used instead of PIO mode to read and write data. DMA channel is responsible for data exchange, which greatly reduces the CPU consumption. However, comparing the CPU utilization of SCSI and IDE, we can find that SCSI still has considerable advantages.
2. The scalability of SCSI is larger than that of IDE. Generally, each ide system can have two IDE channels, with a total of four IDE devices. The SCSI interface can connect 7-15 devices, much more than IDE, and the cable connected is far longer than ide.
3. Although the price of SCSI device is higher, compared with IDE, the performance of SCSI is more stable, durable and reliable.
