Industrial powerline ethernet bridge products

Model: Industrial powerline ethernet bridge 

Working principle: Using OFDM modulation and demodulation technology, the network signal is modulated onto the power line, so that the power line can transmit the network signal while supplying power.

Technical features: Ethernet network signals are transmitted using busbars (or drag chains), with a bandwidth of up to 1200Mbps and a transmission distance of up to 500 meters.

Transmission speed: The bandwidth can reach up to 1200Mbps. In actual use, the bandwidth can reach 400Mbps in the use of 100-meter bridges.

Stability and reliability: The average delay is about 5ms, ensuring the real-time nature of the control signal. There was no disconnection during the test, showing extremely high stability.

Safety: As a wired transmission method, it is not affected by the external environment and has higher stability and safety.

Scope of application: This project is applied to bridge cranes; it is also applicable to logistics warehousing, smart garages, industrial manufacturing, overhead cranes, rail transit, energy, mines, and various types of intelligent robots.

Basic information of bridge erecting machine

Bridge erection machine type: DJ1000 single-girder bridge erection machine.

Purpose: Used for erecting box beams with a span of 40 meters or less and a weight of less than 1,000 tons for high-speed rail and light rail. It is particularly suitable for construction conditions such as bridge-tunnel connection, large slope and small curve, and frequent transfer.

Working principle: It consists of front, middle and rear outriggers and 2 traveling cranes. The gear transmission makes the walking wheels walk on the main beam to realize the walking action of the whole machine under no-load and hoisting conditions.

Control requirements: It is necessary to accurately transmit control signals to each trolley, including lifting, lowering, grabbing and other actions.

Application of industrial powerline ethernet bridge products in bridge erection machines

Application scenario: Ethernet communication is required between the various mechanisms of the bridge erection machine. The industrial powerline ethernet bridge transmission method can effectively solve the strict requirements of the special field environment for control signal transmission.

Signal transmission method:The control signal is modulated and demodulated to the busbar on the bridge erection machine through the industrial powerline ethernet bridge to achieve simultaneous power supply and network supply. Supports mainstream Plcs and various industrial communication protocols on the market (such as Profinet, EtherNet/IP, Modbus TCP).

Software and hardware integration: The industrial-grade power network bridge is seamlessly integrated with industrial control systems such as Schneider PLC to achieve signal transparent transmission between devices.

Performance: Real-time: The average delay is about 5ms, which meets the real-time requirements of the control signal.

Stability: There was no disconnection during the test, showing extremely high stability.

Compatibility: It is fully suitable for the use of bridge erection machines and supports the expansion of subsequent bridge erection machine transformation.

Case sharing: At a bridge construction site in Shaanxi, the bridge erection machine consists of front, middle and rear legs and 2 cranes. The industrial-grade power bridge communication solution is used to transmit control signals, which successfully solves the problem of complex on-site environment and unsuitability for wireless communication.

Customer feedback: Customers are very satisfied with the application of industrial powerline ethernet bridge products on bridge erection machines, believing that it solves the on-site application problems and is willing to continue to use the transmission solution of industrial-grade power bridges in subsequent special scenarios.

Summary and Outlook
