IC card is another new information tool after magnetic card, which refers to integrated circuit card. Bus card is a kind of IC card. The common IC card uses RF technology to communicate with IC card reader. According to its structure, IC card can be divided into general memory card, encrypted memory card, CPU card and super smart card. 1. Memory card, whose embedded chip is equivalent to ordinary Serial EEPROM memory, has the advantages of convenient information storage, simple use, low price of IC card, and can replace magnetic card in many occasions. However, because it does not have the function of information security, it can only be used in applications with low security requirements. 2. The logic encryption card and the encryption memory card are embedded with chips, and the control logic is added outside the storage area. Before accessing the storage area, the password needs to be checked. Only the password is correct, can the access operation be carried out. This kind of information has good confidentiality. 3. CPU card, with chip embedded in the card, is equivalent to a special type of single-chip microcomputer, which has not only controller, memory, timing control logic, but also algorithm unit and operating system. Because CPU card has the characteristics of large storage capacity, strong processing capacity, information storage security and so on.

On July 1, 2019, the long-awaited regulations of Shanghai Municipality on the management of domestic waste was officially implemented, and "waste classification" was incorporated into the legal framework in China. By the end of 2020, the 46 key cities in the pilot area will have basically completed the waste classification and treatment system, and by 2025, the cities at prefecture level and above will have basically completed the waste classification and treatment system. Garbage classification will become a major issue in the health management of major cities in China. In the face of increasingly standardized garbage classification management, effective garbage classification solutions are urgently needed in the market to meet the huge garbage management needs in the future. Garbage classification is a whole chain link, which involves classified delivery, classified collection, classified transportation and classified disposal. There is no link to be missed. Garbage classification is closely related to everyone's daily life, while China has a population of 1.4 billion. The huge amount of garbage means that a huge number of garbage cans are needed for classification and transportation. In the waste classification system, the Internet of things industry is quietly playing a role. The application of the Internet of things enables the intelligent garbage sorting and recycling function to accurately classify, analyze, track and process all kinds of garbage. The traditional grid waste management mainly relies on human cost, which has the problems of high timeliness cost, low problem disposal efficiency and weak construction overall planning mode. The standardized waste classification is in urgent need of supporting waste classification solutions. At this time, lorawan low-power Internet of things based on Lora technology is the most suitable for smart waste classification applications. The solution applied to garbage classification has its special requirements: large amount of connection, low communication frequency, low power consumption, complex coverage environment, high-cost sensitivity. The RF-AL42UH module based on Lora technology and ASR6501 is particularly suitable for waste classification solutions. The garbage can be equipped with a light sensor to monitor whether the capacity of the garbage can is full in real time. A smoke alarm can be installed to monitor the ignition of the garbage can. Sensors send data to Lora terminals or modules. Lora communication is transmitted to Lora gateway thousands of meters away through low-power Lora network. The gateway then transmits the data to the cloud. The cloud reanalyzes the sensor data. Garbage managers can more intuitively understand the filling status of each garbage can in their jurisdiction, and plan the best recycling route for clean vehicles. RF-AL42UH module based on Lora technology has a wide application prospect in garbage classification with excellent performance and flexible networking f...

The initial technology maturity curve for iot development is only based on an increase in the number of deployed and potential sensors. Today, we can look to the future and explore some important success factors. Future trends in the Internet of things, including IoT applications, will bring economic benefits to end users. There is also a trend towards longer battery life, lasting for years. In any wireless iot monitoring system, data transmission consumes power. Therefore, the perception and processing take place at the edge nodes through intelligent partitioning, and the amount of data is reduced (in a more sporadic or shorter period) through local decisions, thus bringing significant added value to the iot system. Finally, the key element of the future is the ability to operate safely and reliably. Therefore, for successful iot systems, the focus of iot design will shift to key performance indicators such as trusted sensors and system uptime. Analysts estimate that low - cost development systems are currently in the Peak of expectation inflation. In the next two to five years, differentiated or specialized high - precision sensors and analog signal chains will become the mainstream and truly push the Internet of things market into the future. Importance of Good Data A key process in iot systems is the conversion of analog signals into digital signals. Simply put, the better the transformation,the more useful the data. Silicon technology innovates to transform and interpret the world around it, bridging the real and digital worlds through detection, measurement, interpretation, and connectivity. The most effective iot deployment is the ability to use this data to determine change. And best change is the biggest value for end customer, such as higher efficiency and higher security, such as in factories, machine learning is not only able to identify when may need to machines for predictive maintenance in the future, but also can identify the details and reach a higher level of recognition, to determine what action to take (for example, to identify specific ball bearing in motor wear). Therefore, the first stage of any iot system is to detect, measure, and then convert real-time signals into analytical data. How well this stage is completed will lay the foundation for future success. If the wrong information data is entered, the results obtained from any iot analysis cloud platform will also be wrong. Therefore, the most successful iot systems have to have measurement and reporting levels that other systems cannot. This needs to improve measurement and reporting makes good hardware essential. A recent Gartner report said the same. Report that they are low cost iot development look fast into the bubble period of disillusionment (trough of disillusionment. This may be due to the plethora of low-cost development platforms available. But I think it's more likely that we're focusing on more challenging iot applications that have more real economic valu...
