Description
Technical field
The utility model relates to electric power system DC control resist technology field, refers to a kind of current conversion station DC control and protection system CAN (Controller Area Network, controller local area network) bus detection system particularly.
Background technology
Some service times can there is the CAN fault of instantaneity in longer current conversion station; for the CAN fault of unknown cause various in current conversion station; there is no the current conversion station CAN maintenance means of pin at present; the current conversion station CAN fault what reason causes can only be judged by artificial experience; so often there will be the situation of current conversion station CAN breakdown judge mistake, bring difficulty to the maintenance of current conversion station CAN.
Utility model content
The purpose of this utility model will provide a kind of current conversion station DC control and protection system CAN detection system exactly, and this system can accurately detect the fault of CAN, facilitates follow-up current conversion station CAN maintenance.
For realizing this object; current conversion station DC control and protection system CAN detection system designed by the utility model; it comprises the CAN of second generation high-voltage dc transmission electric control system; it is characterized in that: it also comprises CAN analyzer, debugging computer and CAN interface; wherein; above-mentioned CAN analyzer is by the CAN of CAN interface access second generation high-voltage dc transmission electric control system, and described debugging computer accesses CAN analyzer.
The utility model achieves the accurate judgement to current conversion station CAN fault by above-mentioned design, and the maintenance for current conversion station CAN provides foundation accurately, improves the efficiency of current conversion station CAN breakdown maintenance.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model;
Wherein, the CAN of 1-second generation high-voltage dc transmission electric control system, 2-CAN analyzer, 3-debugging computer, 4-CAN interface.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Current conversion station DC control and protection system CAN detection system as shown in Figure 1; it comprises the CAN 1 of second generation high-voltage dc transmission electric control system, CAN analyzer 2, debugging computer 3 and CAN interface 4; wherein; above-mentioned CAN analyzer 2 accesses the CAN 1 of second generation high-voltage dc transmission electric control system by CAN interface 4, and described debugging computer 3 accesses CAN analyzer 2.
In technique scheme, CAN interface 4 is PS873 board.
In technique scheme, connected by RS232 serial ports between described debugging computer 3 and CAN analyzer 2.
In technique scheme, described PS873 board is connected by ten heart yearns with between CAN analyzer 2.
The utility model when not changing the second any structure of band high-voltage dc transmission electric control system, can obtain the data of current conversion station CAN, on the normal operation of existing current conversion station without any impact.
Working method of the present utility model is: when needs carry out the detection of current conversion station CAN, debugging computer 3 sends control command to CAN analyzer 2, CAN analyzer 2 obtains message by PS873 board under the ordering about of this control command from the CAN 1 of second generation high-voltage dc transmission electric control system, and message is judged and analyzes, show finally the structural transmission judged and analyze to debugging computer 3, technical staff can know current conversion station CAN according to the display result of debugging computer 3 and whether there is fault.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
