Problems solved by technology

[0005] In order to overcome the shortcomings that the existing network equipment cannot provide multiple basic applications, and the server is too complicated and troublesome to use, the present invention proposes a new type of multifunctional network application equipment. The multifunctional network application equipment has both ordinary network devices It can be used for a long time, has high reliability, and does not require complicated settings. It also has the advantages of providing basic applications with servers built on ordinary PCs or workstations, such as providing web pages, corporate mailboxes, enterprise-level firewalls, enterprise-level network hard disks, Enterprise-level network application system, etc.

Embodiment 1

[0055] figure 1 , figure 2 It is a schematic diagram and functional block diagram of multi-functional network equipment. The serial numbers in the figure indicate: 1. WAN line, 2. LAN line, 3. Power line, 4. Multi-functional network application equipment, 5. Liquid crystal display module, 6.WAN interface, 7.LAN interface, 8.USB interface, 9. Random access memory, 10. Hard disk, 11. Central processing unit, 12. System memory card, 13. Main board, 14. Single-chip microcomputer.

[0056] Such as figure 1 As shown, this embodiment is very simple from the outside, usually only WAN line 1, LAN line 2 and power line 3 are connected to the outside world, which is equivalent to general network equipment. WAN cable 1 and LAN cable 2 are universal crystal connectors, which are easy to connect and operate. The liquid crystal display module used in this embodiment is a low-cost monochrome multi-line dot matrix LCD, and the displayed information is sufficient for this embodiment.

Embodiment 2

[0064] What this embodiment describes is a method for starting a multifunctional network application device. The multifunctional network application equipment uses an industrial computer-style embedded computer system, which is close to a general-purpose PC system, and uses a disk service model. That is, the root location of the system files is always in the disk during the running process. The disk is an important part of the computer running and cannot be separated from other parts of the computer during running. The startup method described in this embodiment is a brand-new startup mode for embedded systems, which abandons the disk service mode commonly used in traditional embedded systems, and transfers the root location of the dedicated device operation file from the conventional disk to the random access memory In the RAM, the tasks of loading device running files, building the original directory structure of device running files, and assigning user rights are completed ...

Embodiment 3

[0080] What this embodiment describes is an online upgrade method for a multifunctional network application device.

[0081] The device operation files of traditional embedded systems are stored in the form of several files, and the storage and operation are interoperable in the same storage space. During the operation of the device operation files, most of the storage files are in the exclusive form. The upgrade system is complicated, and it is necessary to fully consider the dependency relationship and running status between the device's running files. A little carelessness will cause the device's running files to crash. Therefore, the embedded system basically does not have an online upgrade function. The storage structure of traditional embedded systems such as Figure 4 Shown:

[0082] 1. Boot partition, system boot program storage area;

[0083] 2. System partition, storing the system kernel and system files;

[0084] 3. Application partition, storing all application ...

Abstract

The invention discloses a multifunctional network application device, startup and online update method thereof, which relates to a digital communication device. The multifunctional network application device comprises a mainboard, a CPU, a DRAM, a hard disc, a WAN, Lan interfaces, USB interfaces, a SCM, a LCD display module and a system memory card. The CPU is directly connected with the mainboard, the DRAM is connected with the CPU via the slot on the mainbody, the hard disc is connected with the CPU via the interface on the mainboard, the SCM is connected with the mainboard via the interface, the LCD display module is connected with the SCM, and the system memory card is connected with the mainboard via the interface. The use of process control computer mainboard which has various PC interfaces, not only realizes the server function, but also can work continuously as the network apparatus. The invention can provide a plurality of foundation applications such as web page, mailbox, fireproof wall, network hard disc, network application system, FTP, gateway etc.

Description

technical field [0001] The present invention relates to a multi-functional network application device and its start-up and online upgrade method, it is a digital communication device and its operation control method, it is a network service device connected with LAN and WAN, characterized by path configuration, and The invention relates to a starting method for loading and running files of the device and an online upgrading method for the running files of the device. Background technique [0002] Known small-scale servers used by small and medium-sized enterprises are usually common PCs or workstations, and such servers have many disadvantages. First of all, an ordinary PC or workstation is not a dedicated network device, so it is not designed according to the standard of network devices. The basic design requirements of network equipment are high reliability, uninterrupted continuous work, and effective prevention of virus intrusion. However, general PCs or workstations a...
