Telecontrol communication isolation device with bypass control

The utility model relates to a telecontrol communication isolation device with bypass control, which comprises a first system processing unit and a second system processing unit which are mutually independent and are respectively provided with a plurality of network ports. The bypass module is connected with one of the network ports of the first system processing unit and the second system processing unit; and the bypass module only identifies the DL/T634.5104 message in the network data and does not process the message, and the identified message is also forwarded to the corresponding equipment on the other side through the network port. According to the utility model, network connection of equipment in two aspects of transformer station network data acquisition and data uploading is successfully and thoroughly blocked, but normal data interaction of the two kinds of equipment is not interfered, and original protocol communication can also be maintained. The normal production operation is not influenced unde
