POE (Power Over Ethernet) refers to the power of some IP-based terminals (such as IP phones, wireless LAN access points, network cameras, etc.) without making any changes to the existing Ethernet Cat.5 cabling infrastructure. ) is a technology that while transmitting data signals, can also provide DC power supply for such equipment.

In the POE system, there are two important components. Among them, the one that provides power is called PSE equipment (PowerSourcing Equipment, power supply equipment), and the one that uses power is called PD equipment (Powered Device, powered device). The PSE device is responsible for injecting power into the Ethernet cable and implementing power planning and management.

If the network status of the PSE device to be tested is normal, then It is determined that the function of the PSE equipment to be tested is normal.

It can be seen from the above that the PSE equipment detection device provided by the embodiment of the present invention has multiple network ports, and the processor can connect to each network port through the network expansion module, and can detect multiple PSE equipment at the same time, which is more efficient.

The PSE equipment detection device provided by the embodiment of the present invention will be described in detail below through specific embodiments.

As shown in Figure 1, it is a schematic structural diagram of a PSE equipment detection device provided by an embodiment of the present invention. The device includes: multiple network ports 110, a load module 120, a processor 130 and a network expansion module 140.

The input end of the network port 110 is used to connect to any PSE device to be tested, and the power supply line pair at the output end of the network port 110 is connected to the load module 120;

The load module 120 is also connected to the processor 130. The load module 120 is used to independently perform load testing for each accessed network port;

The network expansion module 140 has a plurality of first ports and a second port. Each first port is connected to the data line pair of the output end of each network port 110 in a one-to-one correspondence manner. The second port is connected to the data port of the processor 130 ;

The processor 130 is used to detect the level of the load module 120, and detect the network status of the PSE device to be tested connected to the network port 110 corresponding to the level that meets the preset conditions. If the PSE device to be tested is If the network status is normal, it is determined that the function of the PSE device to be tested is normal.

Among them, the network port 110 can be an RJ45 network socket or an RJ45 plug, etc. The input end of each network port 110 is used to connect to the PSE device to be tested, to receive the power supply voltage of the PSE device to be tested, and to communicate with the PSE device to be tested. data communication. The power supply line pair at the output end of each network port 110 is connected to the load module 120 respectively. The load module 120 can independently perform a power supply load test for each accessed network port.

In a possible implementation, the load module 120 is an integrated circuit and includes a plurality of power supply input interfaces. Each power supply input interface corresponds to a power supply line pair at the output end of each network port 110. The load module 120 can connect each power supply input interface. Perform independent voltage input detection.

In a possible implementation, referring to FIG. 2 , the load module 120 has multiple load sub-modules 121 , and the power supply line pairs at the output ends of each network port 110 are connected to each load sub-module 121 in a one-to-one correspondence. Among them, the dotted line represents data transmission, and the solid line represents power transmission. A load sub-module 121 implements voltage detection for a network port 110. The voltage of the network port 110 is provided by the PSE device under test connected to the network port 110.

For example, the PSE device to be tested may be a POE NVR (Network Video Recorder, network video recorder) device, etc., and the load module 120 may be a PD device, etc.

The load module 120 is connected to the processor 130. The load module 120 can output the voltage detection results of each network port 110 to the processor 130 in the form of levels. The voltage detection levels for different network ports 110 can be input to different pins in the processor 130 to distinguish different network ports 110 .

The processor 130 may be a CPU or a microcontroller, or may be a DSP (Digital Signal Processing, digital signal processor), ASIC (Application Specific Integrated Circuit, application specific integrated circuit) or FPGA (Field-Programmable Gate Array, field programmable gate array). )wait.

The processor 130 detects the level of the load module 120 and determines whether the level is reversed. If the level is reversed, it is determined that the level meets the preset condition; otherwise, it is determined that the level does not meet the preset condition. The level reversal in the embodiment of this application means that the level changes from low level to high level, or the level changes from high level to low level.

For example, when the level of the load module 120 is low in the initial state, after the PSE device to be tested is connected, the level of the GPIO (General-purpose input/output, general-purpose input/output) of the load module 120 will be raised. , when the level of the load module 120 is high in the initial state, after the PSE device to be tested is connected, the GPIO level of the load module 120 will be pulled down. In the embodiment of the present invention, the high level of the load module 120 may be 3.3V, and the low level may be 0V.

In a possible implementation, the load module 120 is connected to the processor 130 through the GPIO port of the processor 130;

The processor 130 is specifically configured to detect the level of each pin of the GPIO port to determine whether there is a level that meets the preset conditions.

The voltage detection levels of different network ports 110 can be input to different pins of the GPIO port of the processor 130, thereby distinguishing the network ports 110 according to different pins.

The data line pairs at the output ends of each network port 110 are connected to each first port of the network expansion module 140 in a one-to-one correspondence. The processor 130 expands the data interface of the processor 130 itself through the network expansion module 140, thereby realizing data communication with multiple PSE devices. For example, the network expansion module 140 may be a Switch chip or the like.

In a possible implementation, the processor 130 is specifically configured to: for a network port corresponding to a level that satisfies the preset condition, detect the packets to be connected to the network port through the PING (Packet Internet Groper, Internet packet explorer) protocol. Test the network status of the PSE device.

The following description takes the initial state as a low level as an example. The processor 130 can detect the network status of the PSE device to be tested through the PING protocol when the level meets the preset conditions. The specific ones can be shown in Figure 3, including:

Step 1: Try to connect to the PSE device under test using the POE protocol.

After the PSE device to be tested is connected to the network port, the corresponding load module starts and attempts to connect with the PSE device using the POE protocol.

Step 2: If the connection fails, the GPIO port corresponding to the load module is low level.

Step 3: If the connection is successful, the GPIO port corresponding to the load module is high level.

Step 4: If the processor detects that the GPIO port is low level for n consecutive times, it is determined that the PSE device to be tested is abnormal, where n is the preset number of times.

The processor performs level detection on the corresponding pin address in the GPIO port according to the preset cycle. If low level is detected for n consecutive times, it is determined that the PSE device to be tested is abnormal and the abnormality is reported.

Step 5: If the processor detects that the GPIO port is high level within n times of detection, the processor sends a PING packet to the GPIO port address corresponding to the PSE device to be tested.

Step 6: If the response of the PING packet is received, it is determined that the PSE device to be tested is normal.

Step 7: If the processor continuously sends PING packets m times without receiving a response, it is determined that the PSE device to be tested is abnormal, where m is the preset number of times.

It can be seen from the above that the PSE equipment detection device provided by the embodiment of the present invention has multiple network ports and can detect multiple PSE equipment at the same time, which is more efficient. Moreover, during the detection process, general software network test PING is used to verify the stability of network communication without setting up a network detection circuit.

In a possible implementation, the processor 130 is also configured to: determine for a network port corresponding to a level that does not meet the preset conditions, determine that the PSE device to be tested connected to the network port is functionally abnormal; Test the PSE equipment to determine whether the PSE equipment to be tested is functionally abnormal.

In order to prevent a single detection abnormality, the processor 130 can perform multiple detections on network ports corresponding to levels that do not meet the preset conditions and PSE equipment under test with abnormal network status. When the preset conditions are not met, or the network status of the PSE equipment to be tested is abnormal after multiple detections, the function of the corresponding PSE equipment to be tested is determined to be abnormal.

In order to use the above-mentioned PSE equipment detection device to detect the PSE equipment to be detected, embodiments of the present application also provide a PSE equipment detection method, as shown in Figure 4. The method includes the following steps:

S401: Establish connections with each PSE device to be tested through multiple network ports.

Among them, the connection can be established through a network cable between the network port of the PSE equipment detection device and the PSE equipment to be tested.

S402: Detect the load module level corresponding to the network port connected to each PSE device to be tested respectively.

For example, for any network port, the level output by the load module corresponding to the network port to the GPIO port can be detected to determine whether the level is reversed. If the level is reversed, determine the level. The preset conditions are met, otherwise the level is judged not to meet the preset conditions.

If the level output from the load module corresponding to the network port to the GPIO port is reversed (from low level to high level, or from high level to low level), it means that the PSE device under test is connected to the network port. powered by. If the level remains unchanged, it means that the PSE device under test connected to the network port is not supplying power.

In a possible implementation, the above method also includes:

Step 1: For the network port corresponding to the level that does not meet the preset conditions, detect the corresponding level of the PSE device under test connected to the network port according to the preset time interval; if the level meets the preset conditions, Then the network status of the PSE device under test connected to the network port corresponding to the level is detected; if the level does not meet the preset conditions, the number of times the level does not meet the preset conditions is updated.

Step 2: Determine whether the number of times the level corresponding to the network port does not meet the preset condition is greater than the preset threshold.

Step 3: If the number of times the level corresponding to the network port does not meet the preset condition is greater than the preset threshold, it is determined that the PSE device under test connected to the network port is functionally abnormal.

If the level does not meet the preset conditions, then the number of times the level does not meet the preset conditions can be recorded. Then, according to the preset time interval, the level of the corresponding pin in the GPIO port is detected. If the level meets the preset conditions, the following steps of S403 are performed. If the level does not meet the preset conditions, the level is updated. The number of times the preset condition is not met.

Furthermore, it is determined whether the number of times the level does not meet the preset condition is greater than the preset threshold. If it is greater, it is determined that the function of the PSE equipment to be tested is abnormal. Among them, the preset number of times can be preset in advance or calculated based on historical detection data, and is not specifically limited.

After determining the functional abnormality of the PSE equipment to be tested, alarm information can be output to facilitate staff to handle abnormal situations in a timely manner.

S403: For the network port corresponding to the level that meets the preset conditions, detect the network status of the PSE device to be tested connected to the network port.

For example, when detecting the network status of the PSE device to be tested, a request packet can be sent to the network port of the PSE device to be tested according to the PING protocol, and then it is determined whether a response packet returned by the PSE device to be tested is received. If received, it is determined that the network status of the PSE device to be tested is normal.

In a possible implementation, the above-mentioned detection of the network status of the PSE device to be tested connected to the network port includes:

Step 1: Obtain the IP address of the PSE device to be tested connected to the network port and obtain the target IP address.

Step 2: Send a request packet to the target IP address according to the PING protocol.

Step 3: Determine whether the response packet returned by the target IP address is received. If so, it is determined that the network status of the PSE device to be tested is normal.

S404: For the PSE device to be tested whose network status is normal, determine that the PSE device to be tested functions normally.

For PSE equipment under test with abnormal network status, multiple tests can be performed. In a possible implementation, the above method also includes:

Step 1: For the PSE device to be tested with abnormal network status, send a request packet to the IP address of the PSE device to be tested according to the PING protocol at a preset time interval; if a response packet returned from the IP address is received, It is determined that the network status of the PSE device to be tested is normal; if no response packet returned from the IP address is received, the number of abnormal network status of the PSE device to be tested is updated.

Step 2: Determine whether the number of network status abnormalities of the PSE device to be tested with abnormal network status is greater than a preset threshold.

Step 3: If the number of network status abnormalities of the PSE device to be tested with abnormal network status is greater than the preset threshold, it is determined that the function of the PSE device to be tested is abnormal.

If the network status of the PSE device to be tested is abnormal, then the number of times the network status of the PSE device to be tested is abnormal can be recorded, and then a request packet is sent to the PSE device to be tested according to the PING protocol at a preset time interval. If received If the response data packet returned by the PSE device to be tested is received, the network status of the PSE device to be tested is determined to be normal. If the response data packet returned from the PSE device to be tested is not received, the network status of the PSE device to be tested is abnormal. frequency.

Furthermore, it can be determined whether the number of network status abnormalities of the PSE device to be tested is greater than a preset threshold. If it is greater, it is determined that the function of the PSE device to be tested is abnormal. Among them, the preset number of times can be preset in advance or calculated based on historical detection data, and is not specifically limited.

After determining the functional abnormality of the PSE equipment to be tested, alarm information can be output to facilitate staff to handle abnormal situations in a timely manner.

It can be seen from the above that the PSE equipment detection device provided by the embodiment of the present invention has multiple network ports and can detect multiple PSE equipment at the same time, which is more efficient.
