Problems solved by technology

[0003] (1) The positive and negative poles of the RS485 port on the acquisition terminal are not insulated, resulting in a short circuit between the positive and negative poles;
[0004] (2) The RS485 port on the terminal is often connected to the RS485 line, and sometimes the RS485 line is loose due to the small port and insufficient screw pressure;
[0005] (3) The RS485 wiring of the on-site terminal is confusing, resulting in a large amount of manpower and time spent on the maintenance process

Embodiment 1

[0023] Embodiment 1: as Figure 1-Figure 2 As shown, a RS485 port connection adapter of a station terminal includes an RS485 adapter 1, the upper end of the RS485 adapter 1 is connected to the positive and negative poles of the RS485 collection port of the station collection terminal 2, and the left and right ends of the RS485 adapter 1 are provided with The positive and negative poles of the RS485 port correspond to the positive and negative ports of the connected RS485 lead-out line 3, and the lower end of the RS485 adapter 1 is detachably connected in series with multiple RS485 adapters 1 in sequence.

[0024] Preferably, the bottom of each above-mentioned RS485 adapter 1 is detachably plugged into the guide rail 4 through a self-locking card slot (similar to the bottom installation structure of a household circuit breaker) and locked with a locking screw 5, and the guide rail 4 is vertically fixedly connected On the inner wall of the installation box of the collection term...

Embodiment 2

[0032] Embodiment 2: A method of using the RS485 port wiring adapter of the station terminal. The method is: according to the needs of use, a plurality of RS485 adapters are installed on the guide rail and locked, and two adjacent RS485 adapters are electrically connected. Paste the label, connect the uppermost one to the collection terminal, connect the required multi-channel RS485 lead-out lines, and cover the transparent cover.

Abstract

The invention discloses a power station terminal RS485 port wiring adapter and a use method thereof, the power station terminal RS485 port wiring adapter comprises an RS485 adapter, the upper end of the RS485 adapter is connected to the positive and negative electrodes of an RS485 acquisition port of a power station acquisition terminal, and the left end and the right end of the RS485 adapter are provided with positive and negative ports of an RS485 leading-out circuit correspondingly connected with the positive and negative electrodes of the RS485 port. And the lower end of the RS485 adapter is sequentially and detachably connected with a plurality of RS485 adapters in series. According to the invention, convenience is provided for RS485 line operation and maintenance, and manpower and time cost are saved under the condition that RS485 line faults are avoided or reduced; since it is difficult to transform the R485 line of the old transformer substation, the economic cost is saved; and the application of the plant station terminal RS485 port switching device reduces the potential safety hazard of short circuit caused by too many parallel connection lines of the RS485 port.

Description

technical field [0001] The invention relates to an RS485 port connection adapter of a station terminal and a method for using the same, and belongs to the technical field of RS485 port connection auxiliary equipment. Background technique [0002] For the substation wall-mounted terminal, due to the unreasonable wiring of the RS485 port, a series of problems will occur when processing the lack of terminal collection: [0003] (1) The positive and negative poles of the RS485 port on the acquisition terminal are not insulated, resulting in a short circuit between the positive and negative poles; [0004] (2) The RS485 port on the terminal is often connected to the RS485 line, and sometimes the RS485 line is loose due to the small port and insufficient screw pressure; [0005] (3) The RS485 wiring of the on-site terminal is confusing, resulting in a large amount of manpower and time spent on the maintenance process. Contents of the invention [0006] The technical problem to...
