Description
Technical field
This utility model is related to RF identification (RFID) technical field, in particular it relates to the vehicle that a kind of four moulds POE powers
Managing device.
Background technology
In general, RFID possess low frequency (125KHz/134.2KHz), high frequency (13.56MHz), hyperfrequency (915MHz),
Four frequency ranges of microwave (2.45GHz, 5.8GHz), the RFID technique involved by this utility model are microwave frequency band.
POE (Power Over Ethernet) refers to not make any in existing Ethernet CAT.5 wirings architecture
In the case of change, for some IP-based terminals (such as IP telephone machine, wireless local network connecting point AP, web camera etc.)
While transmission data, moreover it is possible to provide the technology of direct current supply for this kind equipment.POE technologies can be connected up existing structureization is guaranteed
Ensure the normal operation of existing network while safe, wiring can be simplified, save human cost.Additionally, be only connected to needing
Voltage presence is just had on equipment cable to be powered, therefore is had the advantages that safe.

4,5,7,8 lines be can also occur in nonstandard PSE and upload transmission of electricity stream, 7,8 is positive pole, and 4,5 is the situation of negative pole.Therefore, such as
What improves the compatibility of power receiving equipment, and more than power receiving equipment adaptation the PSE of four kinds of powering modes, allows any one powering mode can
It is normal to use, it is a problem urgently to be resolved hurrily in design.
Common POE read write lines of powering are powered using single mode POE, such as the patent documentation of Application No. 201521060966.0
In disclose single mode POE and power read write line (being called roadside unit), that is to say, that the twisted-pair feeder of power supply is provided in netting twine to being true
Fixed, or being 4,5 to be positive source, 7,8 is power cathode；It is that 1,2 for positive source, 3,6 is power cathode；
It is that 1,2 for power cathode, 3,6 is positive source.The powering mode of actually used middle power receiving equipment has to and power supply unit
Matching, otherwise cannot normal power supply.
Therefore, the compatibility of vehicle management device how is improved, the power supply mould of the compatible various PSE of vehicle management device is allowed
Formula；Become one of current problem demanding prompt solution.
