Electronic switch, each fan electronic switch one fan of correspondence, the on off state for controlling correspondence fan；Fans drive sets
It is standby, it is connected with multiple fan electronic switches, also it is connected with MSP430 single-chip microcomputers, for receiving driving control signal, and based on drive
Dynamic control signal is controlled to multiple fan electronic switches.
Alternatively, in the system, also include：Wireless Telecom Equipment, is connected with MSP430 single-chip microcomputers, for wireless hair
Vehicle traveling direction, each sunlight subgraph is sent to distinguish corresponding position and respectively corresponding area ratio；Radio communication sets
It is standby to be arranged on automobile top；Wireless Telecom Equipment is GPRS communication equipments or 3G communication equipments；Sunlight area data extraction equipment
It is arranged in the front end instrument board of automobile；And solar energy testing equipment may be provided on the roof of automobile.
In addition, the abbreviation of general packet radio service technology (General Packet Radio Service), he is GSM
A kind of available mobile data services of mobile phone user.GPRS can say be GSM continuity.GPRS is passed with the past continuous in channel
Defeated mode is different, is transmitted with package (Packet) formula, therefore the expense that user is born is with its data transmission list
Position calculates, and non-usage its whole channel, in theory inexpensively.The transmission rate of GPRS can be promoted to 56 even 114Kbps.
GPRS is often described as " 2.5G ", that is to say, that this technology is located at the second generation (2G) and the third generation (3G) is mobile
Between mechanics of communication.He is by using untapped TDMA channels in GSM network, there is provided the data transfer of middling speed.GPRS breaks through
GSM nets can only provide the mode of thinking of circuit switching, only by increasing corresponding functional entity and to existing base station system
Carry out part transformation to realize packet switch, the input of this transformation is comparatively and little, but the user data rate for obtaining
It is considerable.And, because the intermediary's converter required for no longer needing existing wireless application, connection and transmission all can
It is more convenient easy.In this way, user can both connect to the internet, the interactive communications such as video conference are participated in, and in same video signal net
The user of (VRN) on network, it might even be possible to without by dialling up on the telephone, and continue and network connection.
In the communication mode of packet switch, data are divided into the bag of certain length to the communication mode of GPRS packet switches
(packet), has a packets headers before each bag (address mark therein indicates that the packet is sent to where).Data transmit it
It is preceding and channel need not be allocated in advance, set up connection.But when each packet is reached, the information in datagram header
(such as destination address), finds an available channel resource and sends the datagram temporarily.In this load mode, number
According to the side's of sending and receiving cochannel between there is no the occupancy relation of fixation, channel resource can be regarded as being total to by all of user
Enjoy and using.A kind of paroxysmal business characteristic is all shown in most cases due to data service, to channel width
Changes in demand is larger, thus using packet mode carry out data transmission be possible to better profit from channel resource.Such as one is entered
The user that row WWW is browsed, the most of the time is in browse state, and the time for being really used for data transmission only accounts for very little ratio.
In this case according to the mode of fixed busy channel, it will cause the larger wasting of resources.
