Market research firm IDC said in a previous report that it is estimated that by 2020, the global IoT endpoints (such as cars, refrigerators, and all connected devices that exist within the Internet of Things) will exceed 29.5 million, up from 10.3 million in 2014 A IDC also said that more and more devices in the Internet of Things market play a role online and that a number of platforms and services will also grow incrementally online.
In this context, IOT software technology development will encounter two bottlenecks: First, how to achieve massive equipment under the rapid retrieval of information, the second is the IoT software development BUG debugging.
On June 30, "Seminar on Breaking IoT Software Technology Bottleneck" was successfully held at Beijing Jingkang Optics Valley Industrial Co., Ltd., an international business road in Beijing Economic and Technological Development Zone.
This seminar covers two core topics: unlimited growth (days) rapid retrieval technology exploration and IoT software programming method innovation.
Reporters saw at the meeting, China's embedded system industry alliance, China Software Industry Association Embedded Systems Branch Secretary Guo Chun learn mathematical methods step by step to infer the existence of integer trees, proved that the integer tree nodes can be unlimited growth, and, The location code of each node on the integer tree corresponds to the value of the node. So, using the newly discovered integer tree data structure, and the newly defined power-of-number (location code for each node in the integer tree), you can quickly make an infinite amount of growth (days) retrieval. In the meantime, Guo Chunxue also explained the rapid conversion algorithm between power system and decimal integer.
Guo Chunxue said that the discovery of integer trees will greatly promote the development and evolution of the underlying core technologies of IoT software and have the practical value of triggering other technological innovations. Further study of integer trees will also have a profound impact on the development of information technology and mathematics.
Zhao Qian, general manager of Digital World Beijing Digital Technology Co., Ltd. believes that the Internet of Things software system BUG, ​​only by setting the correct network space attributes can be resolved.
Zhao Wenyin said that to achieve the logical function of the physical device can also be seen as a "software", and in order to distinguish the concept of traditional computer software, physical devices, as well as running in the physical device software collectively referred to as "big software" .
At present, the Internet of Things is still only existed in a one-dimensional web space container. Obviously, it is very difficult for one-dimensional space to completely describe the things in the three-dimensional space. Due to the lack of information, the logic process also becomes incomplete.
Therefore, Zhao Wenyin think in the Internet of Things first to set a big software can describe things completely accurate dimension of information.
At the seminar, Zhao introduced his FO software development methodology. FO software development method includes three parts: Fact-Oriented Analysis, Frame-Oriented Design and Form-Oriented Programming.
Fact-oriented analysis refers to the fact that customer needs as an existing fact, the use of logical methods for analysis. Structure-oriented design refers to the fact that the analysis process obtained and the connection form of the object sorted out, and expressed in three-dimensional manner. Formal programming refers to building functional modules by writing program code. The module and the configuration (with normalized text description parameters) combine to form an object.
Zhao Wenyin said FO software development methods will help achieve the software factory production.
In Zhao Wenyin's opinion, the existence of BUG in IoT software development is due to the fact that the current IoT is still in a one-dimensional network space container.
Some guests told reporters that FO programming method is based on the object-oriented to do further abstraction, abstract things into a series of tiny structures or members, and then use the technology such as integer trees to design and development of the structure. The same type of members advocated by this method is only developed once, and then applied to the same kind of members according to the principle of self-similarity, which is a disruptive innovation to the software programming method.
In the current software crisis, major software companies are suffering from the increasing complexity of software programming, programming more difficult, longer programming cycles, maintenance and modification difficulties, increasing staff costs, FO programming is expected to receive attention And promote the use of opportunities.
The so-called "software crisis" is the current emergence of a phenomenon in the IT industry.
Prior to the 1960s, software design was designed and compiled on a given computer for a specific application, using machine code or assembly language that is closely computer-dependent. At that time, the software was small and documentation often did not exist. Systematic development methods were seldom used. Designing software often equates to programming. It is basically personal design, personal use, personal operation, self-sufficient personal software production .
By the mid-1960s, the advent of high-capacity, high-speed computers led to a dramatic increase in the number of software developers. High-level language began to appear, the operating system triggered a change in the way computer applications, big data processing led to the birth of the database management system.
Nowadays, the scale of software system is getting bigger and bigger, the complexity is getting higher and higher, and the problem of software reliability is getting more and more obvious. The traditional way of software development is far from satisfying the existing applications, thus triggering a "software crisis" and the impact of the crisis began to widen dramatically after the era of the Internet of Things.
Participants told reporters that the unlimited growth (days) rapid retrieval technology and FO programming techniques as two innovative attempts to build, with China's independent intellectual property rights can be fair and equitable sharing of the Internet of Things software industry, will effectively ease the software crisis Impact on the Internet of Things industry. If we can combine the two new technologies to further organize the development of the corresponding new database, operating system, high-level language, computer architecture and other basic computer hardware and software systems, will be expected to improve the development of computer software in China.
