Embodiment
In order more at large to understand characteristics of the present utility model and technology contents, below in conjunction with accompanying drawing, realization of the present utility model is elaborated.
Fig. 1 is composition structural representation of the present utility model, and as shown in Figure 1, this device comprises control system 11, electric power system 12 and PSE device external button 13; Further, described electric power system 12 comprises PSE chip 121 and at least one PD 122; Wherein,
Described control system 11 is used for Real Time Monitoring PSE chip 121 states, and after detecting, classification completes, and sends power on command according to the interrupt signal of the PSE device external button 13 of receiving corresponding PSE port in the PSE chip 121;
Here, whether whether the described control system 11 real-time detections of meeting receive the interrupt signal of PSE device external button 13, be pressed with certain PSE device external button 13.
Described electric power system 12 be used for to carry out detects, progressive operation, and carries out the operation that powers on to legal PD 122 according to the power on command that described control system 11 sends;
Here, described electric power system 12 is also completed the function of disconnection detection simultaneously in power up, specifically comprise: whether PSE chip detection PD is legal, and when PD is legal PD, PSE chip 121 will carry out normal power supply to PD; When PD was illegal PD, the PSE chip will not powered to PD; Wherein, the PSE chip can according to the IEEE802.3at/af standard utilize 12/36 line to or 45/78 line, the PD that is connected with PSE port in the PSE chip is detected.
Described electric power system 12 also comprises POE status indicator lamp 123, in order to indicate each state of POE power supply process; Described POE status indicator lamp 123 is controlled by described control system 11, can adopt bi-colour light, comprises amber light and green light;
Wherein, described control system 11 sends control command by corresponding PSE port in the PSE chip, controls the light on and off of POE status indicator lamp corresponding to this PSE port; Described POE status indicator lamp comprises three kinds of states: power-up state is waited in the bright expression of amber light, and power-up state is completed in the bright expression of green light, and amber light and green light all do not work expression can not power-up state.
Concrete, after detection, classification step are normally completed, control system 11 will be controlled the bright orange lamp of POE status indicator lamp 123; If detection, classification are not passed through, control system 11 will not lighted POE status indicator lamp 123; After detection, classification are passed through, if control system 11 is received the interrupt signal that PSE device external button 13 provides, will send power on command to corresponding PSE port in PSE chip 121, will light simultaneously the green light of POE status indicator lamp 123 corresponding to this PSE port.
Described PSE device external button 13 is used for producing interrupt signal and reports control system 11, and then control system 11 is sent to the control command of PD 122 power supplies to PSE chip 121 when being pressed.
Fig. 2 is that the physical connection of related each part of the utility model concerns schematic diagram, in Fig. 2 PSE chip 121 first to the PD that is inserted in PSE port 21 detect, progressive operation; Detect and two steps of classification if can normally complete, that is: to recognize equipment to be powered on be legal PD and be that PD distributes correct grade, PSE chip 121 can be with the POE state reporting to control system 11, control system 11 receives transmission of control signals after the state information that reports, the amber light of the POE status indicator lamp 123 that in PSE chip 121, corresponding PSE port is corresponding is lighted, and made PSE chip 121 enter treating power supply state.At this moment, if when PSE device external button 13 produces interrupt signal, control system 11 is according to the PSE port 21 transmission power on command of the interrupt signal of receiving to correspondence; Simultaneously, the green light of the POE status indicator lamp 123 of these PSE port 21 correspondences is lighted.Further, PSE chip 121 22 pairs of legal PD power supplies of twisted-pair feeder by connecting between PSE port 21 and corresponding PD.
Here, the corresponding POE status indicator lamp of each PD, each POE status indicator lamp is the bi-colour light that amber light and green light consist of; And each POE status indicator lamp connects a PSE port of PSE chip.
When a plurality of PD is arranged, press continuously PSE device external button, often to press and once just switch a PSE port, that is: the number of times pressed continuously of PSE device external button equals PSE port sequence number; When by unclamping PSE device external button to wait PSE port corresponding to the PD that powers on the time, continue one section duration and no longer continue to press PSE device external button, think and choose this PSE port, and then PD power supply corresponding to the PSE port that is defined as choosing, PSE device external button produces interrupt signal.Wherein, described one section duration can be according to actual needs and button press set of frequency, such as: generally by dynamic frequency be 2 seconds once, can not arrange greater than pressing in 15 seconds and think and choose PSE port etc.
Based on said apparatus, Fig. 3 is the schematic flow sheet of the utility model implementation method, and as shown in Figure 3, the method comprises:
Step 301: when being connected to the corresponding PSE port of PSE chip wait the PD that powers on, the PSE chip treats that the PD that powers on detects, progressive operation.
Whether the judgement of step 302:PSE chip detects classification results effective, if it is effective to detect classification results, execution in step 303; If it is invalid to detect classification results, return to step 301.
Here, described detection classification results refers to that effectively PD to be powered on is legal PD, and has distributed correct grade for this PD; Described detection classification results is invalid refers to that PD to be powered on is illegal PD or incorrect to the classification results of this PD;
Step 303: the control system POE status indicator lamp amber light that corresponding PSE port is corresponding is lighted, and controls the PSE chip and enter and treat power supply state.
Step 304: judge whether control system receives the interrupt signal that PSE device external button reports, if receive, execution in step 305; If do not receive, return to step 303, the PSE chip is in always treats power supply state;
Here, described control system can detect the interrupt signal that PSE device external button reports in real time; Accordingly, when control system is not received the interrupt signal that PSE device external button reports, control system can't send power on command to any one PSE port of PSE chip, the state of real-time query PSE chip just, and the PSE chip also is in always and treats power supply state; When control system is received the interrupt signal that PSE device external button reports, carry out next step 305.
Step 305: control system sends power on command according to the interrupt signal of receiving to the corresponding PSE port of PSE chip, and lights the green light of POE status indicator lamp corresponding to described PSE port;
Here, specifically selecting PSE port corresponding to PD to be powered on is by pressing continuously PSE device external button, often press and once switch a PSE port, when by to wait PSE port corresponding to the PD that powers on the time, unclamp PSE device external button, continue for some time and no longer continue to press PSE device external button, think and choose this PSE port, be defined as PD power supply corresponding to this PSE port; After choosing the PSE port, control system can send power on command to the corresponding PSE port of PSE chip, and lights the green light of POE status indicator lamp corresponding to this PSE port.
The above is only preferred embodiment of the present utility model, is not be used to limiting protection range of the present utility model.
