Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a two-wire-based data conversion and transmission equipment. Background technique [0002] At present, the dedicated server for medical intercom, the management platform of the nurse station, the management machine of the nurse station, the data conversion and transmission equipment, and the extension equipment of the hospital bed in the ward need to form a complete communication network. [0003] At present, the common equipment networking schemes in hospitals include two-wire power carrier scheme and network cable wiring scheme. Power second-line carrier (that is, supplying power on two lines and transmitting data at the same time) products are divided into two types: low-speed and high-speed. The more common ones in the market are low-speed products. The transmission bandwidth is very small, which cannot meet the information transmission needs of the information age; hig...

AI Technical Summary

Problems solved by technology

Electric two-wire carrier (that is, power supply and data transmission on two lines) products are divided into low-speed and high-speed products. The market is more common for low-speed products, and the transmission bandwidth is very small, which cannot meet the information transmission needs of the information age; high-speed The product has a large transmission bandwidth, but generates a lot of heat

Both low-speed and high-speed products have the following defects: 1. The integrated modules in each device are expensive; 2. The heat generation is large, and it is prone to overheating and cause system instability; 3. It is easy to be interfered by surrounding signals, resulting in poor signal quality ;4. The whole system is paralyzed when the equipment is faulty or short-circuited; 5. Centralized power supply requires too much power. The network capacity is weak. When the number exceeds a certain number, it is necessary to add another host or add a relay device

The characteristics of network cable networking are high reliability, but the construction volume is huge, the construction period is long, the construction cost is high, the wire consumption is large, the wire cost is high, the switching equipment is large, and the switching equipment cost is high
