Description

Technical Field

[0001] The utility model relates to rail transit technology, and more specifically, to a connection device for system debugging. Background Art

[0002] As an important part of urban transportation, the subway has the advantages of high efficiency, high speed, punctuality, large capacity, and high density, and undertakes the main demand of modern urban passenger transportation. However, since the opening and operation of the lines in many cities, the on-site equipment has been used at a high load for nearly or more than 10 years or even longer. According to the general service life of computer hardware equipment being 5-8 years, in order to ensure the safe and reliable operation of the subway lines, a large number of equipment on the subway lines need to be updated and transformed one after another.

[0003] The subway power comprehensive monitoring system is generally connected to professional on-site equipment through 485 hard wires, 422 hard wires, and RJ45 network ports to the communication controller in the power control panel. When upgrading and transforming the control signal panel (hereinafter referred to as the "control panel"), the new control panel is placed close to the original control panel after arriving at the site. The communication lines originally connected to the old control panel need to be removed, and then connected to the new control panel correspondingly, and then various debugging works are carried out. After all the debugging works are successfully completed, the old control panel is removed and the new control panel is enabled. Considering the importance of the subway in urban transportation, the equipment transformation of the subway line cannot affect the rigid requirement of the normal operation of the line. Generally, the equipment transformation of the subway line can only be switched and debugged during the night outage time, and must be restored or completed before the normal operation time during the day. Therefore, each switching and debugging can only be carried out in multiple batches, and enough time for disassembling and installing the cables must be reserved, resulting in an extended upgrading and transformation period and low efficiency.
