Embodiment 1

[0039] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for compatible PSE chips, the method comprising:

[0040] S101, the central processing unit CPU sequentially scans the PSE chip through the channel corresponding to the interface set on the POE switch main board; the corresponding channel of the interface set on the POE switch main board includes an IIC channel and a UART channel;

[0041]S102, if the PSE chip is scanned through any one of the channels corresponding to the interface set on the main board of the POE switch, then determine the corresponding driving function of the PSE chip according to any channel;

[0042] S103, the CPU invokes the driver function and sends a control instruction to the PSE chip through any channel to complete the control of the PSE chip.

[0043] It is worth noting that the function of the driver function in S102 is to enable the CPU to control the PSE chip to supply power to the POE switch port through t...

Embodiment 2

[0065] Such as Figure 5 As shown, Embodiment 2 of the present invention provides a device compatible with PSE chips, including a POE switch main board 201, the interface provided on the POE switch main board 201 is connected to the PSE chip 202, and the device also includes:

[0066] The scanning module 203 is used to scan the PSE chip 202 through the channel corresponding to the interface provided on the POE switch main board 201 in turn; the corresponding channel of the interface provided on the POE switch main board 201 includes an IIC channel and a UART channel;

[0067] The processing module 204 is used to scan the PSE chip 202 if any channel in the channel corresponding to the interface provided on the POE switch mainboard 201, then determine the corresponding driver function of the PSE chip 202 according to any channel; call the driver function and pass any One channel sends control commands to the PSE chip 202 to complete the control of the PSE chip 202 .

Embodiment 3

[0074] Such as Image 6 As shown, Embodiment 3 of the present invention also provides a device compatible with PSE chips, the device comprising:

[0075] A POE switch main board 301, the POE switch main board is provided with a CPU 302, an IIC channel 303, a UART channel 304, and interfaces for connecting the IIC channel 303 and the UART channel 304 to other devices;

[0076] The CPU 302 is configured to: sequentially scan the PSE chip 306 through the channels corresponding to the interfaces connected to other devices; if the PSE chip 306 is scanned through any channel in the channels corresponding to the interfaces connected to other devices, Any of the channels determines the corresponding driver function of the PSE chip 306; calls the driver function and sends a control instruction to the PSE chip 306 through any of the channels to complete the control of the PSE chip 306;

[0077] A PSE board 305 , on which a PSE chip 306 is disposed, and the PSE board 305 is movably conn...

Abstract

The present invention provides a method and device compatible with PSE chips, which are used to solve the problem in the prior art that the switch cannot be used after the PSE chip using the IIC interface or UART interface is discontinued, and realizes that the same POE switch main board supports different types of PSE chip compatible. The method is applied to the main board of the POE switch, and the interface provided on the main board of the POE switch is connected with the PSE chip. The channel corresponding to the interface includes IIC channel and UART channel; if the PSE chip is scanned through any channel of the channel corresponding to the interface set on the main board of the POE switch, the driver function corresponding to the PSE chip is determined according to any channel; the CPU calls the driver function And send control commands to the PSE chip through any channel to complete the control of the PSE chip.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device compatible with PSE chips. Background technique [0002] POE (Power Over Ethernet) refers to the transmission of data signals for some IP (Internet Protocol, network protocol)-based terminals without any changes to the existing Ethernet wiring infrastructure. Technology that can provide DC power for such devices. The difference between a POE switch and an ordinary switch is that the POE switch has a built-in PSE (Power Sourcing Equipment, power supply device) chip, which is used to control the power supply function. The CPU (Central Processing Unit, central processing unit) of the POE switch can obtain the state of the PSE chip through a fixed interface. [0003] But in the prior art, a kind of PSE chip can only communicate with CPU through a kind of interface, the most commonly used is IIC (Inter-Integrated Circuit, integrated circuit bus) interface ...
