Description

Under a kind of mountain environment many communication systems of the intelligence of electric vehicle alternating-current charging pile and Method
Technical field
The invention belongs to new energy and communication technical field, it is related to electric vehicle alternating-current charging pile under a kind of mountain environment The many communication systems of intelligence and method.
Background technology
Electric vehicle alternating-current charging pile is for Vehicular charger provides safe and reliable AC power, for public, family With, lease or residential property electric vehicle alternating-current charging, install simple and convenient, can be with vehicular, portable, wall-mounted and fall Ground formula.Alternating-current charging pile is made up of pile body and electrical module, and input and the AC network of charging pile are directly connected to, output end dress There is charging plug for for charging electric vehicle.The communication of charging pile relates generally to three aspects：Communicated with power distribution station and remote Process control Platform communication and communicated with cell management system of electric automobile.The communication modes that traditional charging pile is used are more single One：Or use wired mode, mainly wired ethernet or industrial series bus；Or wireless mode is used, it is main using shifting The mobile data access service (GPRS/CDMA) of dynamic operator.At present, existing alternating-current charging pile communication modes do not consider environment Influence, however, under different geographical, weather environments, the communication quality of different communication modes has a great difference, especially In complicated mountain environment, single communication modes can not meet requirement, dumb.
Wired mode is limited larger by geographical environment, and wiring is complicated, autgmentability is poor, construction cost is high and very flexible, existing Some alternating-current charging piles use single GPRS public network communication modes mostly, and communication fee is higher, and if public network carrier network Break down and can not repair in a short time again, the communication of alternating-current charging pile will be greatly affected, especially contour in remote bill control Level application of function it is more, to power information collection requirement of real-time it is higher in the case of, user will be badly influenced and filled in time Electricity.
Additionally, existing alternating-current charging pile communication system is without 230M and power carrier mode, only GPRS public networks communication party Formula, communication modes are more single.230MHz wireless private networks are electric power dedicated frequencies, and private network is special, is served only for industry user, does not have Traffic peak, reduces data delay and the possibility for blocking, and improves the real-time of data transfer.In terms of communication efficiency, 230MHz private networks real-time is good, operation expense is relatively low, be easy to extension, can flexible networking, and allow under certain conditions Same frequency is used with original system, the shared of communication equipment is realized.On the other hand, GPRS public networks concurrency is good, but public network is logical The running quality of letter relies on mobile operator to a great extent.But the wireless communication technology of 230MHz private networks and GPRS public networks There is communication blind district.Three kinds of communication modes cut both ways, and are only dynamically selected according to communication environment, adjusted, combined, ability Play greatest benefit.
Have the advantages that investing low, equipment installs simple, plc communication technology using power line carrier (PLC) communication mode Passage with power circuit as carrier signal transmission, without new route, effectively reduces communications cost, and power line carrier communication Reliability is high, and high voltage transmission line is firm in structure, and the safe design coefficient of high voltage transmission line safe design coefficient ratio optical fiber is high.But Plc communication is low due to the availability of frequency spectrum, and transmission range is short, and interference is big, is less suitable for existing bandwidth requirement high, needs and other modes Being combined could provide reliable and stable communication support.
The content of the invention
In view of this, the intelligence it is an object of the invention to provide electric motor car alternating-current charging pile under a kind of mountain environment is led to more News system and method, by the parallel method realized in alternating-current charging pile of multiple communication modes, so as to efficiently solve not With the communication issue under environment；For more traditional alternating-current charging pile, the scope of application is wider, improves communication quality, it is ensured that Efficient communication between alternating-current charging pile and remote control table and platform area power distribution station.
To reach above-mentioned purpose, the present invention provides following technical scheme：

λ = Σ i = 1 3 ω i y i , ( ω i = { 0.4 , 0.35 , 0.25 } ) - - - ( 1 ) .
5. under a kind of mountain environment according to claim 3 electric vehicle alternating-current charging pile many means of communication of intelligence, its It is characterised by：In step s3, calculating judgement is carried out to communication environment value using direct method, the direct method is direct by charging pile Reading communication index carries out calculating judgement, specifically includes：
The index of communication quality can be characterized by alternating-current charging pile actual measurement, the communication quality index read by system is sentenced to recognize Disconnected current communication environment, the communication quality index includes but is not limited to downloading rate/RSRP values；The key of direct determining method It is to calculate alternating-current charging pile remote signalling amount threshold values, formula (2) is threshold values computing formula：
ϵ = Σ i = 1 3 ϵ i ϵ i = α i β i t - - - ( 2 )
The remote signalling amount threshold parameter of table 2 and result of calculation
In step s3, the direct method and indirect method are carried out simultaneously；
In step s 4, from the point of view of according to the result of calculation of formula 2 and table 2, remote signalling amount threshold values takes 140.8kbps-1；To make direct method With the unification of indirect method result of calculation digit, environment judgment value is normalized, therefore, environment decision threshold takes 0.14；When straight Then it is that communication environment is good by communication environment grade discrimination during the result of calculation of connection and indirect method all simultaneously greater than 0.14, starts GPRS/CDMA wireless public network communication modes；Otherwise for communication environment is poor, start 230 radio communication modes.
