Description
Technical field
The present invention relates to test macro and the method for feeder ear equipment in a kind of electric power system based on local area network (LAN), particularly whether a kind of feeder ear equipment that can test out in electric power system is test macro and a kind of method of testing of utilizing this test macro to realize that meets the standard device of agreement.
Background technology
POE(Power Over Ethernet, electric power system based on local area network (LAN)) refer at existing Ethernet Cat-5(Catagory 5cable, a kind of twisted-pair feeder, can be designed to signal transmssion line or network cable) in wiring architecture situation about not making any changes, be that some are based on IP(Internet Protocol, the agreement interconnecting between network) terminal is (as IP phone machine, wireless local network connecting point AP(Access Point, WAP (wireless access point)), web camera etc.) when transmission of data signals, kind equipment provides the technology of direct current supply for this reason, POE technology can guarantee the normal operation of existing network in safe guaranteeing that existing structure connects up.
But, owing to meeting the very high cost of standard P OE equipment needs of agreement, now having there is on the market a lot of nonstandard POE equipment, these nonstandard POE equipment, all without POE chip, do not have the automatic detection function of POE.And some is to take directly to use DC power supply as the feeder ear equipment (PSE of POE product in nonstandard POE equipment, Power Sourcing Equipment) to network power supply, cause the illusion of POE power supply, but this pattern is used netting twine in fact exactly as power line, and do not meet real POE supply standard, receiving end equipment (the PD of POE product under this pattern simultaneously, Powered Device) can not carry out voltage stabilizing, cause terminal equipment to have serious potential safety hazard.
When the nonstandard POE equipment of another part adopts charger to power to network in receiving end equipment built-in power module or outside acceptor, this pattern also can reach the object of network power supply, but be the consensus standard that feeder ear equipment or receiving end equipment all do not meet an IEEE 802.3af(Power over Ethernet) standard, thereby may cause receiving end equipment can not access POE switch, cannot carry out resource-sharing, also have certain potential safety hazard simultaneously.
Although there is a lot of nonstandard POE products on market, but whether the POE product that at all cannot test out purchase due to domestic consumer is standard device, cause can having serious potential safety hazard and cannot carrying out resource-sharing when using nonstandard POE product, also be easy to cause the damage of the network equipment, to user, cause a lot of unnecessary trouble and losses simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is whether be standard device in order to overcome in prior art user if cannot test POE product, cause can there be serious potential safety hazard when using nonstandard POE product, be easy to cause the defect of the damage etc. of the network equipment, provide whether a kind of feeder ear equipment that can test out in electric power system is test macro and a kind of method of testing of utilizing this test macro to realize that meets the standard device of agreement.
The present invention solves above-mentioned technical problem by following technical proposals:

Because feeder ear equipment in the POE product of standard is all with automatic detection function, when detecting the receiving end equipment of different power consumption grade, feeder ear equipment all can be exported the power matching with the level of power consumption of the current receiving end equipment being connected.Therefore, the 3rd checkout gear 3 replaces the receiving end equipment of different power consumption grade with the resistance of different power consumption grade, this feeder ear equipment is detected, if this feeder ear equipment can not be exported the power matching with the level of power consumption of the current resistance being connected, illustrate that this feeder ear equipment is non-standard equipment, therefore the POE product with this feeder ear equipment is also nonstandard product, thereby has avoided user because using nonstandard POE product to cause unnecessary trouble and loss.
Finally, the 4th checkout gear 4 is by after this feeder ear equipment short circuit, detects whether output voltage of this feeder ear equipment, if, judge that this feeder ear equipment is as a non-standard equipment, if not, call this decision maker 5 and judge that this feeder ear equipment is as a standard device.
Because the feeder ear equipment of standard all has short-circuit protection function, this feeder ear equipment output voltage no longer when short circuit namely, until circuit recover just can output voltage after normal.Therefore, if detecting this feeder ear equipment, the 4th checkout gear 4 there is short-circuit protection function, again in conjunction with this first checkout gear 1, the detection of this second detection device 2 and the 3rd checkout gear 3, standard device when this feeder ear equipment is just described, and be also the POE product of standard with the POE product of this feeder ear equipment, and if this feeder ear equipment does not have short-circuit protection function, also i.e. output voltage still when short circuit, just illustrate that this feeder ear equipment is non-standard equipment, therefore the POE product with this feeder ear equipment is also nonstandard product, thereby avoided user because using nonstandard POE product to cause unnecessary trouble and loss.
As shown in Figure 2, the method for testing that the present invention utilizes the test macro of the present embodiment to realize comprises the following steps:
Embodiment 2:
As shown in Figure 3, the difference of the test macro of the present embodiment and embodiment mono-is: in the present embodiment, this test macro also comprises one the 5th checkout gear 6, for detection of this feeder ear equipment, whether adopt mid-span method or end cross-over connection method to power, if, call this first checkout gear 1, if not, call this decision maker 5 and judge that this feeder ear equipment is as a non-standard equipment.
Wherein, when specific implementation, the 5th checkout gear 6 can utilize rectifier bridge to detect, and the known technology that this has belonged to this area, just repeats no more at this.
As shown in Figure 4, the method for testing that the present invention utilizes the test macro of this enforcement to realize comprises the following steps:
Step 200, detect this feeder ear equipment and whether adopt mid-span method or end cross-over connection method to power, if so, perform step 201, if not, perform step 205.
