Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage cable laying equipment, and in particular to a wireless measurement and control system and its application in intelligent high-voltage cable laying equipment. Background Technology

[0002] High-voltage cable laying employs a mechanical traction method. Cable reels are transported by cable laying machines, and traction machines pull the cable body via steel wire ropes through several cable conveyors and turning trolleys to deliver the cable to the designated location. High-voltage cable laying is divided into two categories: conventional laying and intelligent laying. Conventional laying equipment uses electrical control lines for control signal transmission, while intelligent laying equipment uses fiber optic lines. When using high-voltage cable laying equipment, control lines (including electrical control lines or fiber optic lines) of equal length to the laying path need to be laid. A central control platform and several monitoring and control boxes monitor and control the equipment in the entire laying system. During the laying process, the central control platform acts as a power and information integration platform. Power and control lines are connected from the central control platform to the wiring inlet of the next-level monitoring and control box, and then from the outlet of the next-level monitoring and control box to the wiring inlet of the next-next-level monitoring and control box, connecting step by step until covering the entire laying site. Therefore, the control network cabling distance is long and very complex. Furthermore, when using fiber optic cables to transmit signals, the central control platform and the measurement and control box must have physical interfaces to expand and connect the equipment. The measurement and control box must have incoming / outgoing fiber optic interfaces inside and outside for signal transmission between the measurement and control boxes. Moreover, the internal and external wiring of the incoming / outgoing fiber optic interfaces inside and outside the measurement and control box must correspond one-to-one. If the fiber optic connections inside and outside the measurement and control box are inconsistent, the signal transmission between the measurement and control boxes will be interrupted.

[0003] In summary, in long-distance high-voltage cable laying projects, the large intervals between the first and last devices of the laying system (i.e., between the central control platform and several intelligent measurement and control boxes) and the entanglement between power lines and control lines make the wiring situation on the high-voltage cable laying site very complicated, leading to difficulties in on-site maintenance.

The wireless module networking is flexible, and the connection between the main wireless module and sub-wireless modules is quick, allowing for easy addition of new devices and rapid integration of new device nodes into the existing network for remote monitoring.

[0066] In some embodiments of this utility model, reference is made to Figure 2The first main wireless module 110 includes a first main antenna, the first sub-wireless module 210 includes a first sub-antenna, the second sub-wireless module 310 includes a second sub-antenna, and the third sub-wireless module 410 includes a third sub-antenna. The antennas are used to receive and transmit wireless signals.

Depending on actual needs, a second intelligent conveyor may be set up at a location further away from the main control platform 100. However, the second intelligent conveyor is not within the wireless communication range of the first main wireless module 110.

The second main wireless module 420 then uploads the status information of the second conveyor to the first main wireless module 110 through the third sub-wireless module 410 to increase the information transmission distance.

[0072] It should be noted that the specific location mentioned above is only one embodiment. A new main wireless module can be connected to the sub-wireless module at the edge of the coverage area of ​​the first main wireless module 110 according to the actual situation. This should not be regarded as a limitation of this utility model.

[0073] In some embodiments of this utility model, reference is made to Figure 2 and Figure 7 The second main wireless module 420 includes a second main antenna, and the fourth sub-wireless module includes a fourth sub-antenna. The antennas are used to receive and transmit wireless signals. The main antenna can communicate wirelessly with each sub-antenna within its coverage area, but the sub-antennas do not communicate with each other. It should be noted that the second main wireless module 420 and the fourth sub-wireless module may also include other components; their specific structures and working principles are prior art known to those skilled in the art and will not be described in detail here.

[0074] In some embodiments of this utility model, the wireless communication between the first main wireless module 110 and the first sub-wireless module 210, the second sub-wireless module 310, and the third sub-wireless module 410 employs a long-distance transmission protocol for information transmission.
