The embodiment of the invention discloses a signal transmission device and method. The signal transmission device provided by the embodiment of the invention comprises a direct-current power supply, main equipment, a direct-current power supply line and a load, the main equipment comprises a first switch, and the main equipment is configured to transmit a signal to the load through the direct-current power supply line when the first switch is in an off state; and the DC power supply is configured to supply power to the load through the DC power supply line when the first switch is in the on state. Based on the technical scheme, when the first switch in the main equipment is turned off, the direct current power supply line is used for transmitting the signal to the load, a signal transmission line does not need to be additionally arranged, a wireless signal transmission mode is avoided, the wiring mode can be simplified, signal transmission can be reliably carried out, and the system cost is reduced.
Description
technical field [0001] Embodiments of the present invention generally relate to the field of electronic power, and in particular, to a signal transmission device and method. Background technique [0002] Using DC power supply lines to supply power to multiple loads is a common power supply method in the field of power electronics. However, if signal transmission / control operations are required for multiple loads in a signal transmission device, additional signal transmission lines or wireless method of transmission. [0003] However, the method of adding signal transmission lines will increase the complexity of wiring and adversely affect the stability of the system, while the method of wireless transmission will greatly increase the system cost and be susceptible to wireless electromagnetic interference, which will affect the signal transmission. Reliability is adversely affected and, in some cases, the issue of signal transmission security is also involved. SUMMARY OF T...
