Description

Technical Field

[0001] This utility model belongs to the field of rail-water intermodal transport and control technology, specifically relating to a rail-water intermodal transport and control system based on an industrial equipment ring network. Background Technology

[0002] The rail-water intermodal transport centralized control system mainly consists of on-site industrial equipment. Each main industrial equipment has its own controller. Traditional system integration cannot simply connect to the centralized control system through an industrial ring network to transmit industrial control data, safety monitoring system data, and power monitoring data.

[0003] Conventional centralized control systems are based on a star network structure. Connecting all industrial control equipment point-to-point in a physically dispersed space generates a large number of network devices and communication cables, resulting in increased construction costs and significantly higher material costs for communication cables. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model designs a centralized control system for rail-water intermodal transport based on an industrial equipment ring network. This centralized control system is based on a ring Ethernet network, which features secure and reliable communication, stable signal acquisition, and a long service life.

[0005] This utility model discloses a centralized control system for rail-water intermodal transportation based on an industrial equipment ring network, which adopts the following specific scheme: The rail-water intermodal transportation centralized control system includes a network structure composed of network-side equipment, OLT central office equipment, multiple passive optical splitters, and ONU terminal equipment. Multiple industrial control devices are connected in the network structure. The OLT central office equipment is connected to the network-side equipment at the upper level, and the OLT central office equipment is connected to a passive optical splitter network with multiple passive optical splitter architectures at the lower level. The ONU terminal equipment is connected to other ONU terminal equipment. The passive optical splitter network transmits data from the OLT central office equipment to the ONU terminal equipment through the passive optical splitters, and the passive optical splitter network combines the optical signals sent by N ONUs into one optical signal for transmission to the OLT central office equipment.

[0006] Furthermore, the passive optical splitter network is a two-level networking architecture network.

[0007] Furthermore, there are two OLT central office devices, each with one PON port, forming a daisy-chain networking configuration, which is a two-level PON system.

[0008] Furthermore, the network-side equipment uses two core switches, which are two identical switch configurations and are redundant with each other.

[0009] Furthermore, the connected industrial control equipment includes a tippler equipment controller, a sewage treatment equipment controller, a temperature and vibration controller, a belt conveyor general contracting controller, a belt cooling water controller, a safety monitoring controller, a coal shed fogging controller, a bucket wheel excavator controller, and controllers for the No. 1 and No. 2 centralized control centers. All connected industrial control equipment are equipped with communication interfaces that uniformly support the PROFINET communication protocol.

[0010] Furthermore, the rail-water intermodal transport control system also includes an industrial control hyper-converged backend, which provides IaaS services such as computing, storage, and networking, including a host computer with a display screen that displays uploaded industrial control data, security monitoring system data, and power monitoring data in real time.

[0011] The advantages of this utility model are:

[0012] This utility model adopts the above-mentioned technical solution, which can integrate data from multiple subsystems on an industrial equipment ring network and uniformly adopt the standard communication protocol PROFINET, ensuring the stability of data interaction between the systems, while saving the use of communication cables and optical fibers, thus saving money.

[0013] The conveyor control system is highly scalable and flexible. In the industrial equipment ring network, there is no limit to the number of nodes. Multiple network nodes can be added or removed. The performance requirements of the control units of various brands of industrial control equipment are not high. If a problem occurs in a single industrial network node, it will not affect the operation of other industrial equipment. Attached Figure Description

[0017] This utility model provides a centralized control system for rail-water intermodal transport based on an industrial equipment ring network. (See also...) Figure 1 , Figure 2 ,like Figure 1As shown in this embodiment, a rail-water intermodal transport centralized control system based on an industrial equipment ring network is provided. The rail-water intermodal transport centralized control system includes a network structure consisting of network-side equipment, OLT central office equipment, multiple passive optical splitters, and ONU terminal equipment. Multiple industrial control devices are connected in the network structure. The OLT central office equipment is connected to the network-side equipment at the upper level and to a passive optical splitter network with multiple passive optical splitter architectures at the lower level. The ONU terminal equipment is connected to other ONU terminal equipment.

[0018] The industrial control equipment is configured with a communication interface that uniformly supports the PROFINET communication protocol. Different protocols can be converted through corresponding gateways to access the ring network switch using a unified standard protocol.

[0019] In this embodiment, two OLT central office devices are used, and their number can be arranged according to distance and location. The switch configurations are kept consistent, and they are connected in a ring network via optical ports. The characteristic of a ring network is that Ethernet can still operate normally when one or more fault points occur, and the ring network switching time is less than 50ms. Optical signals are transmitted between the ring network switches via optical fiber.

[0020] The network-side equipment described in this embodiment uses two core switches, which are connected to the ring network for connection with the upper-layer industrial control hyperconverged back-end equipment, thereby achieving network redundancy and improving the stability of core data exchange.

[0021] The rail-water intermodal transport control system described in this embodiment also includes an industrial control hyper-converged backend, which provides IaaS services such as computing, storage, and networking. It includes a host computer with a display screen that displays uploaded industrial control data, security monitoring system data, and power monitoring data in real time.

[0022] The two core switches described in this embodiment are two sets of identical switch configurations, and they are redundant with each other.

[0023] The industrial control equipment described in this embodiment includes a tippler equipment controller, a sewage treatment equipment controller, a temperature and vibration controller, a belt conveyor general control unit, a belt cooling water controller, a safety monitoring controller, a coal shed fogging controller, a bucket wheel excavator controller, and controllers for the No. 1 and No. 2 centralized control centers. All subsystem controllers are equipped with communication interfaces that uniformly support the PROFINET communication protocol.

[0024] This embodiment's industrial control hyperconverged backend, with corresponding application software installed, provides a unified, distributed storage service including hard disk, file storage, object storage, and backup, supporting massive data storage and unlimited capacity expansion. Primarily geared towards resource management and maintenance personnel, it offers functions such as resource creation, daily monitoring and alarm management, log management, work order management, security management, and cost management. After uplinking through the PON system, it connects to the smart factory communication network via the OLT interface, enabling the interface between intelligent manufacturing MES, ERP, PLM, and other systems and underlying physical devices, thereby achieving industrial control, data acquisition and analysis, and video surveillance.

[0025] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
