Description

Technical Field

[0001] The invention relates to the technical field of power control systems, in particular to a power line broadband carrier communication group network control system. Background Art

[0002] Power line broadband carrier communication group is mainly used in power control systems. For example, signals need to be transmitted between two substations, such as the closing status, voltage, current, safety control, etc. This signal cannot be transmitted in other ways at present, and can only be transmitted on the cable by carrier, because the power cable needs to diagnose whether the transmission cable is broken.

[0003] The power line broadband carrier communication group is mainly composed of a power line carrier machine, power lines and coupling equipment. The signal is modulated to the power line by the carrier machine at one end, and after being transmitted on the power line, it is demodulated on the carrier machine at the other end. However, the carrier machine is generally installed in the equipment room, and the scene is very noisy due to the sound of equipment operation, which is not in the normal operation of the control system. Summary of the invention

[0004] The present invention provides a power line broadband carrier communication group network control system, which can improve the operating environment of operators and enable carrier communication to be operated in a low-noise machine room.

[0005] The present invention adopts the following technical solutions.

[0006] A power line broadband carrier communication group network control system, the control system comprising a signal sending device (100) located in an equipment room and connected to a carrier machine (400); the signal sending device is connected to a signal receiving device (200) located in an operating cabinet (500) in a machine room via a communication cable (300); the operating cabinet is provided with a transparent door (3) adjacent to a display surface of a signal display component of the signal receiving device on the front side, and is also provided with a shift plate (5) integrated with an operating module of the signal receiving device; the shift plate is adjacent to a clearance opening (4) at the transparent door and is connected to a pull switch (6); when the operating module needs to be operated, the pull switch is pulled to drive the shift plate to move and extend from the clearance opening.

[0007] The number of the shifting plate, the giving way opening or the pulling gate is more than one.

[0008] The communication cable is provided with an inner core made of metal material.

[0009] The transparent door of the operating cabinet is set to a normally closed state to save room space and reduce noise.

[0010] A vertical slide rail (7) is fixed in the operating cabinet, and a horizontal cross plate (8) is connected to the upper end of the slide rail. A telescopic rod (9) parallel to the slide rail is provided on the cross plate. The end of the telescopic rod is connected to a vertical slide rod (10) slidably connected to the slide rail. Both ends of the vertical slide rod are hinged with guide rods (11), and the guide rods are hinged at the upper and lower ends of the shift plate. A limit rod (12) located at the lower edge of the clearance opening is provided in the door panel (3) of the transparent door, and the sliding gate is connected to the end of the telescopic rod through a curved plate (13).

[0011] When the gate is pulled downward, the gate drives the vertical sliding rod, the guide rod, and the shifting plate to move downward synchronously. When the shifting plate moves downward to contact the limit rod, the guide rod flips toward the side where the clearance opening is located relative to the vertical sliding rod, and drives the shifting plate to move horizontally along the limit rod toward the side where the clearance opening is located and extend out of the clearance opening.

[0012] The end of the telescopic rod is connected to the vertical sliding rod via a cross bar (14), and a tension spring (15) is provided on the outer sleeve of the telescopic rod; one end of the tension spring is connected to the cross plate, and the other end is connected to the cross bar; a long hole (16) for the vertical movement of the shutter is provided at the side frame (2) of the transparent door, and a limit hook (17) is also hinged on the side frame and is located at the lower end of the long hole;

[0013] When the shift plate extends out of the clearance opening, the limit hook can be hung on the pull gate to limit the pull gate, so as to maintain the state of the shift plate extending out of the clearance opening. At this time, the limit hook restricts the pull gate and the shift plate from moving upward. When the limit hook no longer limits the pull gate, the tension spring resets the shift plate with elastic force.

[0014] The cross bar is connected to the middle position of the vertical sliding bar.

[0015] A drag chain (18) for burying a wire (19) is provided on one side of the moving plate and the slide rail, and the wire is led out from the moving plate for connecting to an operating module.

[0016] A support rod (20) extending toward the slide rail is provided at the end of the vertical slide rod, and the support rod is provided with a pulley (21) for connecting to the slide rail; and connecting ears (22) for hingedly connecting to the guide rod are provided at the upper and lower ends of one side of the shift plate.

[0017] Compared with the prior art, the beneficial effect of the present invention is that the carrier machine that originally needed to be operated between the equipment is led to the machine room for operation through the network control system, that is, the signal sending equipment, communication cables, signal receiving equipment, and operating cabinet connected in sequence. The signal originally transmitted through the carrier is transmitted again in the form of an electrical signal through the communication cable, and finally the operator can perform the corresponding operation on the operating cabinet. The operating environment is improved compared with before.

[0018] The operating cabinet in the present invention is different from the traditional cabinet. During operation, it is not necessary to open the entire door panel like a door and then operate in the cabinet, so the space occupied by the machine room can be greatly reduced; due to the operating module in the operating cabinet of the present invention, only a part of the switch-type devices that can be manually controlled are occupied, and many of them are signal display devices. If the door panel is opened, it will occupy the already compact space in the machine room, so a new operating method is proposed, that is, by pulling the gate downward, the shift plate originally located in the operating cabinet and above the clearance port is moved downward and then extended out of the clearance port. The shift plate is integrated with an operating module for the staff to operate, and other display modules can be directly viewed through the transparent door panel, so that the transparent cabinet door does not need to be opened for operation.

[0019] In the present invention, by providing a plurality of shift plates, clearance openings and pull gates, the operation areas can be divided according to the different functions of the operation modules, so that the number of operation modules integrated on a single shift plate is small, the shift plate does not appear bulky when moving, and the operation experience can be improved. At the same time, the wires and cables at the shift plate are arranged in the drag chain, which can prevent the movement of the shift plate from affecting the wires.
