Description

Technical Field

[0001] The utility model relates to the technical field of a network management machine, in particular to a heat dissipation type network management machine. Background Art

[0002] The communication management machine is also called DPU or gateway. It has multiple downstream communication interfaces and one or more upstream network interfaces. It is equivalent to a front-end machine, i.e. a monitoring computer. It is used to organize and summarize the communication data of all intelligent monitoring / protection devices in a substation, and then send it to the upper-level master station system (back-end machine of the monitoring center and DCS) to complete the remote signaling and telemetry functions.

[0003] On the other hand, it receives commands from the backend computer or DCS and forwards them to the intelligent series units in the substation to complete the remote control of the opening and closing of each switchgear in the substation or the parameter setting of the device, realizing the remote control and remote adjustment functions. At the same time, it should also be equipped with multiple serial interfaces to facilitate communication with other intelligent devices in the substation.

[0004] Communication management machines are generally used in substations and dispatching stations. Communication management machines control downlink equipment through control platforms, collect information such as telesignaling, telemetry, and remote control, and feed messages back to the dispatching center. Then, the administrator of the control center processes and analyzes the messages and selects the commands to be executed to achieve the goal of outputting dispatching commands. The existing communication management machines have poor heat dissipation effects, which greatly affects the service life of their internal components.
