Description

A kind of POE switch test device and detection method thereof

Technical field

The present invention relates to wireless local area network technology field, particularly relate to a kind of POE switch test device and detection method thereof.

Background technology

Institute of electrical and electronic engineers IEEE have approved Power over Ethernet POE standard (IEEE802.3af) in June, 2003, electric power detection and control item in its clear stipulaties remote system, and the mode that routers, switch and hub are powered to equipment such as IP phone, safety system and Wireless LAN access points by Ethernet cable specifies.The development of IEEE802.3af contains the effort of many company experts, and this also makes this standard to be checked in every respect.

POE (PowerOverEthernet, pass through Power over Ethernet), POE powers and refers to existing Ethernet CAT-5 wiring architecture, when it goes without doing any change, by conventional Ethernet cable supply electric power while transmission data, thus ensure this cable for ethernet end device as IP telephone machine, wireless local network connecting point AP, safety network camera and some other IP-based terminal transmission data signal while, the ability of direct current supply can also be provided by kind equipment for this reason.POE technology can ensure the normal operation of existing network while guaranteeing existing structureization wiring safety, reduces costs to greatest extent.

In POE switch system, the equipment of power supply is provided to be called as power supply unit (PSE, PowerSourcingEquipment), and using the equipment of power supply to be called power receiving equipment (PD, PowerDevice), the capital equipment of Power over Ethernet is PSE, its is responsible for detection, classification of PD, powers on, the functions such as open circuit detection.Once when certain PD is loaded, PSE will detect the access of PD immediately, and will cut off the electricity supply when equipment is removed.PSE also must provide overcurrent protection, suffers damage to prevent PSE and PD.Five class netting twines of standard have four pairs of twisted-pair feeders when carrying out transfer of data, but common web camera only uses two couple wherein in l0MBASE-T and 100MBASE-T.IEEE802.3af allows two kinds of usages, applies idle pin when powering, and 4,5 pin connect for positive pole, and 7,8 pin connect for negative pole.When application data pin is powered, DC power supply is added in the mid point of transmission transformer, does not affect the transmission of data.Line can be any polarity to 1,2 and line to 3,6 in this manner.802.3af standard does not allow to apply above two kinds of situations simultaneously.Power supply provides equipment PSE can only provide a kind of usage, can simultaneous adaptation two kinds of situations but application of power equipment PD is necessary.This standard regulation power supply normally 48V, 13W.PD equipment provides 48V to be easier to the conversion of low-voltage, but should have the insulation safety voltage of 1500V simultaneously.

In view of the technical background of above POE switch, and the main application fields of POE switch is wireless aps, IP phone, the first-class network application based on IP end product of IP network shooting, and its power demand is generally no more than 15.4W.The communication well-known switch producer of industry, as H3C (China three), Huawei, Shanghai Bell have made the examination criteria of POE all for POE exchanging mechanism.Existing detection scheme is the supply power mode adopting fixing civil power 220VAC/50Hz, adopt under the environment of normal temperature 25 DEG C and support that DC fixed voltage is the single port POE network power supply device of 12V, detected service behaviour and the network performance of POE by operational network tester, and use kilowatt meter to detect the power supply power consumption of POE.This single port POE network power supply device has 2 100Mbps network ports, and wherein 1 is general network access interface, and another one is POE output port, separately has a power input interface.

There is defect and the drawback of these aspects following in the shortcoming of prior art:

1. POE network power supply device on current market lacks flexibility, be mainly manifested in DC voltage all unification fix, can not carry out free adjustment, unrestricted choice, POE network power supply device function ratio is more single, the nonoptional leeway of DC voltage and expanding space;

2. in the environmental reliability inspection of POE module, adopt fixing ambient temperature, humidity environment detects, to detect in normal temperature 25 DEG C of environment as only required, and less than detecting in the environment of high temperature 55 DEG C or low temperature-10 DEG C, this is just present in one and detects the incomplete problem of covering, and the use scenes that have ignored POE switch system is the environment of a dynamic change at user side.In addition, the Primary Component of POE switch system, as comparatively responsive to the requirement of ambient temperature, humidity in components and parts such as master chip, power supply chip, SDRAM, Flash chip, crystal oscillators, these devices as worked under hot environment, low temperature environment, hot and humid environment, all may cause change and the decline of systematic function because of the change of device parameters, thus cause the operation irregularity of machine system;

3. existing detection technique is when detecting the heat dispersion of POE switch system, lacks the measurement of the heat dispersion to system parts, fuselage lower cover, fuselage upper cover, DC input terminal, PCB, adapter PCB.National compulsory regulation GB4349.1-2011 (Information Technology Equipment safely) has and has formulated standard in this respect, requirement system works operation under normal temperature environment, the PCB temperature of system does not allow more than 110 DEG C, the temperature of casing surface temperature and other Primary Components does not allow more than 85 DEG C, but existing detection method is not very well to the monitoring of the working temperature of system, whether everybody only pays close attention to POE switch system and normally works, and have ignored system temperature and to exceed standard the burning machine problem that can cause;

4. POE switch system is applicable to the supply district that alternating voltage is 100-240VAC ~ 50/60Hz, but existing POE switch system detection method all only adopts the power supply of 220V/50Hz to detect, and does not cover various different alternating voltage, different supply frequencies.POE switch system is when running its all properties, as higher or on the low side in run into alternating voltage, the phenomenon that the complete machine electric property all likely having influence on POE switch system lost efficacy and declined.Power supply statutory standard is clear stipulaties country variant, the alternating voltage that different regions use and supply frequency, if American Power standard is AC120V/60Hz, China's power standard is AC220V/50Hz, Japan's power standard is AC100V/50Hz, European Union's power standard is AC230V/50Hz, Australia's power standard is AC240V/50Hz, TaiWan, China power standard is AC110V/60Hz, Korea S's power standard is AC220V/60Hz, therefore the existing detection method of current POE switch system to there is Test coverage face incomplete, various different alternating voltage can not be used in by checking system preferably, the electric property of various different electrical power frequency, omit the reliability to electric property, the monitoring of stability.As POE switch system causes burning machine because electric property is bad, power on and off, configuration loss, system reboot, crashes, all can badly influence normal use and the personal safety of user side.In addition, bad defect also can cause great economic loss to manufacturing enterprise and produce bad public praise and brand image.

Below be exactly what time defect and the drawback of existing POE switch system detection method, the electric property of POE switch system complete machine can not be detected preferably, all sidedly, environmental reliability performance, machine system temperature performance, POE carry Ethernet service performance.Existing detection method, only detect for the index of certain function in system, only detect for the index of certain module in system, the detection method of this serial, system compatible sex chromosome mosaicism can not be excavated preferably, sense cycle also can be caused to extend, affect product development progress and systems axiol-ogy efficiency.
