Description

\! Μί3β% r ^ i, 92113155 ____ ^ Modified January 5th: ^ ϋ⑴. [Technical field to which the invention belongs] The present invention is a single-chip monitoring server, which mainly uses a single-chip microcontroller as an Internet dynamic The monitoring server can be used for remote monitoring or data collection through its function of long-distance bidirectional data and command transmission. It can also be used for instruments and equipment that require an embedded server. [Previous technology] Today people live in an information age. Internet technology has entered people's work and life, browsing information online, exchanging information through email, and file transfer, etc., to make people feel It is easy and simple to exchange information, so the Internet has become an important part of the current information society. However, until now, Internet technology has mainly been used for information exchange between people (or groups). For example, e-mail (_ 丨 1), webpage (Webpage) browsing, etc., even if "" ^ further application of technology, such as e-business, only stay in the business with enterprises or with individuals in business Information exchange. If so, it restricts people from other fields to obtain important information that is closely related to people's work and life. They are controlled, for example, from some electronic equipment. One disagreement is that users' applications have been increasingly concentrated on two ft devices in daily life, such as mobile phones, cars, vending machines, electrical 2 = security systems, medical monitoring equipment, etc .; these electronic devices They all have some features, that is, they have an embedded microcontroller, which can provide functions, services, and control functions, and can obtain and use some information.

Description of the invention… mongolian ⑵ 92113155 said to amend these electronic devices with n t e r n e t so that people can remotely obtain information about these electronic devices and control their operation. Because the microcontroller itself is a small microprocessor, with built-in memory and control programs, a small chip can increase the additional price of the product. Therefore, the microcontroller has always been a favorite in the system design and automatic control industry. One of the architectures; because of its small size, it contains countless technologies, applications, knowledge, and business opportunities. In the past, data collection from remote field devices through dedicated communication lines, and remote display and control technology are not without, but the disadvantage is that

The communication medium should be dedicated, the communication protocols should be written by themselves, and the supporting software and hardware should be designed by themselves.

As long as the remote display and control of 'embedded devices can access the Internet, its conventional shortcomings can be solved, and the level is very high, and no dedicated communication line is needed; because the existing global network infrastructure can be separated from you Spread across the sea to the ends of the earth, the speed is astonishing, coupled with the Internet protocol is readily available and open, any web browser can be connected to monitor, up to 丨 0 million bits ( Mbyte) complete desktop browser, as small as 6,000 kilobytes (kbyte) Mosaic browser, whether it is Microsoft browser or Netscape browser; information Directly reflected on colorful web pages, the form can be data, text, images, tables or voice, real-time data will be automatically updated, 'the operation of the device will have timely visible and even audible feedback. But how do ’embedded devices access I n t e r n e t? In principle

獍 Amended in January, 199213155—I. As long as the embedded device is transformed into a Web server, plus the Transmission Control Protocol / Internet Protocol (TCP / IP) network protocol, You can go to Internet. The principle is one, and there are many different technologies. The conventional solution has the following methods: 1. Utilize the system on the Micro Processor Unit (MPU), for example, the system-level chip developed by sicom company NET + AR M is the most orthodox solution. Already. It is the micro-processing of the smart property rights architecture of Arm A RM 7 using Reduced Instruction Set Computing (RISC) technology with a processing speed of 40 MIPS (Million Instruction Per Second; Millions of instructions per second). Device (micrcore), plus Ethernet (Ethernet); use the following network protocols · Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Reverse Address Translation Protocol (RARP), Internet Control Report Protocol (ICMP); the following high-level software protocols on the Internet: Hyper File Transfer Protocol (HTTP), Simple Mail Transfer Protocol (SMTP), File Transfer Protocol (FTP); and then includes the real-time operating system (pSOSRTOS, Integrated system (System on a Chip; S0C) composed of integrated system company's operating system. For example, when the above SOC is embedded into a printer, it can be connected to the Internet to become an online printer, making any Internet Clients can use this printer to monitor, control and control the printer on their web pages. 2. Using 32 / 64-bit embedded single-chip microcontroller system, it has sufficient capabilities and resources to follow the above-mentioned soc-like thinking in operating system b.

Implemented effortlessly with the support of the sum function. 3, 8 / 16-bit embedded single-chip microcontroller system, the principle of implementation is not different from the above, but should take care that the 8 / 丨 6-bit system is not fast enough and the memory is not large enough, think about some The method is to simplify and keep the most basic things, that is, the embedded device must be transformed into a web server, and the TCP / IP network protocol must be added.

However, the technical difficulties of using the embedded single-chip microcontroller system to access the Internet described above are: how to use the limited source of the microcontroller itself to perform Tcp / iKm fixed processing on the information to make it into IP data that can be transmitted on Intern ^ package. At present, there are two schemes to solve this problem: one is a personal computer (pers〇nal c〇mputer; pc) gateway + dedicated, 罔, the other is a 32-bit microcontroller (Microcontroller; MCU) + timely operation system (Real-Time OS; RT0S).

The PC gateway + private network solution uses a private network (such as RS232, RS485 ′ CAN Bus, etc.) to connect a small batch of single-chip microcontroller systems together, and then connects the private network to a pc. This pc has the function of converting the information on the private network into a Ηττρ agreement data packet, and then sending it to the online persistent information sharing. This solution can connect a variety of single-chip computers, but it has the following disadvantages: it relies on the PC as a gateway for protocol swapping. In the case of multiple single-chip computer systems, the private network is inconvenient to deploy; Protocol conversion software, and the second body is usually provided by a third-party software vendor at a higher cost. One person

I / P agreement processing; thanks to the use of high-end single-chip microcomputers, this solution can open the function of ‘ί ί ί. Its shortcomings: high-end microcontrollers are more expensive, development weeks are longer, and expensive RT0S development software needs to be purchased, and: when people are quoting, they must also consider the Internet protocol and other regulations at the same time 2: increase The complexity of application development requires higher development capabilities of developers. "Slave Moon Dagger" [Summary of the Invention] The main purpose of the present invention is to solve the above-mentioned shortcomings and avoid
