The invention discloses a multifunctional intelligent
data collecting device, which comprises a power source board, a CPU board, a CPU expansion board and a
bus back board and at least comprises one of an AC sampling board, an AS sampling board and an FT3 serial sampling board. The device cannot only support network transmission of IEC61850-9-2 standard and point-to-point transmission, but also supports point-to-point transmission of IEC60044-8 and an extension protocol thereof. The device can realize collection and transmission of data, has a
cascade function, and can receive sampling data and combine the sampling data with data in the device. The device has intelligent PT paralleling and
voltage switching functions, sends and receives state information and alarm information via a
GOOSE (Generic Object Oriented Substation Event) message, and supports a
GOOSE network control function. The device supports an IEEE1588 high-accuracy network time setting function, supports a GMRP (Garp
Multicast Registration Protocol) protocol and automatically carries out VLAN (Virtual
Local Area Network) division. The device has an intelligent debugging function and can carry out flexible configuration,
dynamic simulation, automatic diagnosis, automatic check, and the like.
