Embodiment Construction

[0035] Adopt embedded CPU, low power consumption. No need for fans;

[0036] The airtight case is adopted, which is not easy to be affected by dust.

[0037] The printed board adopts three defenses, which can effectively prevent dust and corrosion.

[0038] It adopts a 19-inch chassis structure and is easy to install on the cabinet. At the same time, the anti-seismic performance is greatly improved.

[0039] The use of industrial hard drives can increase the temperature range of the device and improve the shock resistance of the hard drive.

[0040] Solid state disks can also be used instead of hard disks. Provide reliability.

[0041] Multiple network ports can be expanded, up to 6 100Mbps Ethernet ports can be expanded.

[0042] Multiple serial ports can be expanded, RS-232, RS-485, RS-422, and optical fiber serial ports can be expanded.

[0043] a) The whole system is divided into two parts as a whole according to real-time and human-computer interact...

Abstract

The invention relates to a method for achieving background monitoring based on an embedded device, which adopts the embedded device with high-performance configuration to achieve the part with strong real-time requirements in the former background system and put the former non-real-time application requiring human-computer interactions on a portable PC machine as a background terminal which is only used when a transformer station is maintained. All data or files associated with a terminal program on the portable PC machine are stored in the embedded device but not stored in the PC machine. Thus, the portable PC machine for maintenance can be applied to maintaining all transformer stations adopting the background monitoring mode.

Description

technical field [0001] The invention relates to an operation method of background monitoring in a substation comprehensive automation system. Background technique [0002] At present, the substation integrated automation system has been widely used in all levels of substations. Its stable and reliable operation is the guarantee for the safe operation of substations. The background monitoring system is the collection point of all data, and its security is particularly critical. Since the background monitoring machine requires real-time operation, the amount of processed data is very large, the response speed is required to be fast, and it is in a strong electromagnetic environment, so general commercial PCs cannot meet the requirements, and even industrial computers have unsatisfactory performance. Large-scale workstations will inevitably increase the investment cost of the substation, and these machines are powered by AC, and their reliability is affected. [0003] The mode...
