Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present utility model and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the utility model described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1:
as shown in fig. 1 and 2, the present embodiment provides a remote power supply control device, which includes an insertion detection device 1, a power supply conductive control terminal 2, a power receiving conductive control terminal 3, a power supply interface 4, and a power receiving interface 5;
the power supply conductive control end 2 and the power supply interface 4 are arranged on power supply equipment, and the power receiving conductive control end 3 and the power receiving interface 5 are arranged on power receiving equipment;
the power supply conductive control end 2 is electrically connected with the insertion detection device 1;
the insertion detection device 1 is configured to determine that the power supply apparatus and the power receiving apparatus are connected by a circuit when detecting that the power supply conductive control terminal 2 and the power receiving conductive control terminal 3 are connected by a circuit, so as to control the power supply apparatus to supply power to the power receiving apparatus through the power supply interface 4 and the power receiving interface 5.
It should be noted that POE refers to providing dc power for a terminal device while transmitting a signal by using a network cable without changing an ethernet wiring infrastructure, which is abbreviated as ethernet power supply. In fact, pure power is supported to be transmitted in a long distance under a normal state of a circuit, but the power over Ethernet is utilized to supply power to POE and simultaneously data signals are transmitted, the data signals are transmitted on a physical medium inevitably to have attenuation and distortion, and when the attenuation or the distortion reaches a certain degree, the effective and stable transmission of the signals is affected.
Thus, the POE power supply distance of 100 meters is obtained to ensure the furthest distance that the data signal can be transmitted before a minimum frame is transmitted when the transmission rate is 100 Mbps. If the remote transmission is to be realized, the Ethernet port needs to be reduced by a lower width, and in the Ethernet with high speed, the POE power supply distance cannot be free from the limitation of 100 meters. In addition, a PSE control chip is required to be added at the power supply equipment end for POE power supply, a PD detection chip is required to be added at the power receiving equipment end, and the manufacturing cost of the equipment is increased.
Therefore, the utility model adds the power supply control interface on the power supply equipment and adds the corresponding power receiving control interface on the power receiving equipment, so that the control process of automatically supplying power to the power receiving equipment is realized when the power receiving equipment and the power supply equipment establish circuits through the power receiving control interface and the power supply control interface. The power supply mode replaces the POE power supply mode, reduces the manufacturing cost of equipment, is not limited by the power supply distance in the power supply process, and can be applied to a remote power supply scene.
Preferably, the power receiving electric control terminal 3 includes a first power receiving control interface and a second power receiving control interface, and the first power receiving control interface and the second power receiving control interface are shorted.
Preferably, the power supply conductive control terminal 2 includes a first power supply control interface and a second power supply control interface, where the first power supply control interface and the second power supply control interface correspond to the first power receiving control interface and the second power receiving control first interface.
Preferably, the first power supply control interface, the second power supply control interface and the power supply interface 4 are arranged on a socket of the power supply equipment, the first power receiving control interface, the second power receiving control interface and the power receiving interface 5 are arranged on a plug of the power receiving equipment, when the plug is plugged into the socket, the power receiving control interface and the corresponding power supply control interface are connected in a circuit, and meanwhile, the power receiving interface 5 and the power supply interface 4 are connected in a circuit.
Specifically, when the power supply equipment supplies power, a 4-bit power supply socket is adopted, and the power supply socket comprises a first interface, a second interface and a fourth interface. The first interface and the fourth interface of the power supply socket are a first power supply control interface and a second power supply control interface respectively, and the second interface and the third interface of the power supply socket are power supply interfaces 4.
The first interface and the fourth interface of the power supply socket are used for completing plug insertion detection, and the second interface and the third interface of the power supply socket are used for realizing a power supply function.
The power supply plug used for being connected with the power supply socket on the power receiving equipment adopts a 4-bit plug as well. The first interface and the fourth interface of the power supply plug are a first power receiving control interface and a second power receiving control interface respectively, and the second interface and the third interface of the power supply plug are power receiving interfaces 5.
The second interface and the third interface of the power supply plug are used for being connected with the second interface and the third interface of the power supply socket in a one-to-one correspondence mode so as to complete power supply of power supply equipment to powered equipment, and the first interface and the fourth interface of the power supply plug are in short circuit.
Preferably, the insertion detection means 1 is configured to detect a voltage between the first power supply control interface and the second power supply control interface, and the insertion detection means 1 is configured to determine that the power supply device and the power receiving device are to establish a circuit connection when detecting that the voltage is at a low level.
Specifically, when the plug is plugged into the socket, the four first interface pairs of the power supply plug and the four first interface pairs of the power supply socket are in circuit connection.
Because the first interface and the fourth interface of the power supply plug are electrically connected with the first interface and the fourth interface of the power supply socket in a one-to-one correspondence manner, the first interface and the fourth interface of the power supply socket of the power supply equipment also become a short circuit state, so that the voltage between the two interfaces changes.
When the insertion detection device 1 detects that the power supply socket is changed from the high level to the low level between the first interface and the fourth interface, it is determined that the power receiving device and the power supply device are in circuit connection, that is, the power receiving device needs to supply power, and then the power supply device is controlled to supply power to the power receiving device through the second interface and the third interface of the power supply socket and the second interface and the third interface of the power supply plug.
The insertion detection device 1 may be a device capable of detecting a level change, such as an MCU or a CPLD of a power supply apparatus.
Preferably, the insertion detection means 1 is configured to determine that the power supply apparatus and the power receiving apparatus are disconnected from the circuit to control the power supply apparatus to stop supplying power to the power receiving apparatus when the voltage is detected to be at the high level.
When the plug is pulled out from the socket, the first interface and the fourth interface of the power supply socket of the power supply equipment are disconnected, the insertion detection device 1 detects that the low-level side between the two interfaces is high level, and then the power supply equipment is controlled to cut off the power supply of the second interface and the third interface of the power supply equipment, so that the power supply socket of the power supply equipment is not electrified, the power supply equipment interface is not electrified under the condition that the power receiving equipment is not connected, and the power supply safety of the power supply process is improved.
Preferably, the insertion detection means 1 is configured to control the power supply apparatus to supply power to the power receiving apparatus after a delay of a preset time after determining that the power supply apparatus and the power receiving apparatus establish the circuit connection.
In this embodiment, after the plug is inserted into the socket, when the MCU or the CPLD inside the power supply device detects that the level change is low, the power supply device is controlled to supply power through the second interface and the third interface after delaying for 1 second, so that the power supply is prevented from being too fast in the insertion process, and the contact is prevented from sparking, so that potential safety hazards exist.

The remote power supply control device in the utility model is arranged in the extension type leather station, so that the purpose of low-cost remote power supply can be realized, and the remote power supply control device can be widely applied to different power supply distance scenes; meanwhile, in the process of realizing power supply control through the remote power supply control device, the power supply equipment interface is effectively ensured to be uncharged when the power receiving equipment is not connected, and the power supply safety is improved.
