Problems solved by technology

[0003] In the application scenario where the coaxial cable is used to transmit power, the receiving device needs to be a POC device. Since the power is transmitted through the coaxial cable, the voltage amplitude received by the receiving device through the coaxial cable is relatively high, for example, it can be 24V or 48V , if the receiving device is a non-POC device or is a POC device but has not switched to the POC state, the power output from the source device directly to the receiving device will cause damage to the receiving device

Embodiment Construction

[0022] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0023] The embodiment of the present invention provides a power transmission system, such as figure 1 As shown, the power transmission system includes a receiving device 11 and a source device 12. The receiving device 11 and the source device 12 are connected through a coaxial cable 13, and the transmission of the control signal and the transmission of the power signal are realized through the coaxial cable 13.

[0024] The source device 12 is used to output the first level voltage V1 to the receiving device 11 through the coaxial cable 13, so as to activate the controller in the receiving device 11 to read whether the receiving device 11 supports POC transmission power signal, and after receiving the receiving device 11 After the first feedback signal that supports the PO...

Abstract

The present invention provides a receiving device, a source device and a power transmission system, the receiving device is connected to the source device through a coaxial cable and receives a power signal, and the receiving device is used to receive the first level voltage through the coaxial cable , start the controller in it to read whether the receiving device supports POC transmission of power signals, and if so, feed back the first feedback signal supporting POC transmission of power signals to the source device, and wait to receive the target standard voltage transmitted through the coaxial cable . The power transmission system in the embodiment of the present invention can prevent the source device from directly outputting the target standard voltage to the receiving device, and prevent damage caused by the receiving device being a non-POC device.

Description

Technical field [0001] The present invention relates to the technical field of power transmission through coaxial cables, and in particular to a receiving device, a source device and a power transmission system. Background technique [0002] In the prior art, there is a technology that transmits power and signals through the same coaxial cable, and this technology is referred to as POC (Power over coaxial cable) for short. Using the POC technology, it is possible to transmit power and signals from a source device (Source device) to a sink device (Sink device), and Sink devices are usually required to be POC devices. [0003] In the application scenario of using coaxial cable to transmit power, the receiving device needs to be a POC device. Since the power is transmitted through the coaxial cable, the voltage amplitude received by the receiving device through the coaxial cable is relatively high, for example, it can be 24V or 48V If the receiving device is a non-POC device or altho...
