IIC, that is, Inter-Integrated Circuit (IC bus), this bus type are for connection to whole
Body circuit, IIC are a kind of multidirectional control buss, that is to say, that multiple chips may be coupled under same bus structure, while every
A chip all can serve as the voltage input of real-time Data Transmission.This mode simplifies signal transmission bus interface.It can make two
Any one of a I2C main equipment is connect with shared resource.PCA9545 can be such that two I2C main equipments are mutually being not connected to
In the case where be connected with same from equipment, to simplify the complexity of design.I2C bus allows to connect different transmission
The equipment of rate.The synchronizing process of clock signal is known as synchronizing between multiple devices.In addition, more instead of I2C with single device
Multiple chips in a primary device application, effectively save system cost.
The line that IIC is used is few；I2C universal serial bus generally has two signal wires, and one is two-way data line SDA, separately
One is clock line SCL；All serial data SDA being connected on I2C bus apparatus are connected on the SDA of bus, each equipment
Clock line SCL is connected on the SCL of bus.
IIC transmission is not easy confusion, in order to avoid the confusion of bus signals, it is desirable that each equipment is connected to the output end of bus
Shi Bixu is error of omission open circuit (OD) output or open collector (OC) output.Serial data line SDA interface circuit in equipment is answered
This be it is two-way, for sending data in bus, input circuit is used to receive the data in bus output circuit.And it is serial
Clock line also should be it is two-way, as the host of control bus data transmission, on the one hand will by SCL output circuit send when
On the other hand clock signal will also detect the SCL level in bus, to decide when to send next clock pulses level；
As the slave for receiving Host Command, the signal on SDA is sent or received by the SCL signal in bus, it can also be to SCL
Line issues low level signal to extend the bus clock signal period.When bus free, because each equipment is all open-drain output, pull-up
Resistance Rp makes SDA and SCL line keep high level.The low level of any appliance output will all be such that corresponding bus signal line becomes
It is low, that is to say, that: the SDA of each equipment is "AND" relationship, and SCL is also "AND" relationship.In order to be communicated, it is total to be each connected to I2C
The equipment of line has a unique address, in order to which host is looked for.The data transmission of host and slave can be sent out by host
Slave is transmitted data to, host can also be dealt by slave.All equipment for sending data to bus is known as transmitter, from bus
The upper equipment for receiving data is referred to as recipient.
(NMOS, CMOS can be simultaneous for all not special requirement of manufacturing process and electricity frequency of the bus to equipment interface circuit
Hold).Rate of data signalling in I2C bus may be up to ten myriabit per second, when high speed mode more than 40 myriabit per second.Separately
Outside, the number of devices connected is allowed to be limited with its capacitance no more than 400pF in bus.Server terminal control module and cloud
The GPRS at data storage center is communicated.
Internet 5 is the abbreviation of general packet radio service technology (General Packet Radio Service), it
It is a kind of available mobile data services of gsm mobile telephone user.GPRS can say be GSM continuity.GPRS and continuously exist in the past
The mode of channel transmission is different, is transmitted with package (Packet) formula.Therefore the expense that user is born is with its transmission
Data unit calculates, and not uses its entire channel, theoretically inexpensively.The transmission rate of GPRS can be promoted to 56 even
114Kbps.RS 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.It is by providing the data transmitting of middling speed using not used TDMA communication in GSM network.GPRS is broken through
GSM net can only provide the mode of thinking of circuit switching, only by increasing corresponding functional entity and to existing base station system
Part transformation is carried out to realize packet switch, the investment of this transformation is comparatively and little, but obtained user data rate
Considerable.Moreover, connection and transmission are all because no longer needing intermediary's converter required for existing wireless application
It can be more convenient to be easy the packet (grouping) of length, having a packets headers before each packet, (address mark therein indicates this point
Group is sent to where).It does not need to allocate channel in advance before data transmission, establishes connection.But it is reached in each data packet
When, according to the information (such as destination address) in datagram header, temporarily finds an available channel resource and send the datagram
It goes out.In this transmission mode, there is no fixed occupancy relationship, channel money between the side's of sending and receiving cochannel of data
Source can be regarded as being used by all user sharings.Since data service all shows a kind of dash forward in most cases
The business characteristic of hair property, it is larger to the changes in demand of channel width, therefore carrying out data transmission using packet mode will be more
Channel resource is utilized well.
5 principal entities of internet include GPRS backbone network, GGSN, SGSN, Home Location Register HLR, in mobile switch
The heart (MSC, VLR Visitor Location Register (VLR), mobile station, packet data network (PDN), in short message service gateway mobile switch
The heart (SMS.GMSC) and short message service interworking mobile switching centre (SMS.IWMSC) etc..
Data realize that grouping sends and receives, the transmission speed of 56~115Kbps, the visit of the 9.6kbps relative to GSM
It is unusual for asking speed.GPRS possesses the access speed of 171.2kbps；In terms of connection setup time, GSM needs
10-30 seconds, 10 times of GSM of speed can also steadily transmit the high quality audio and video file of large capacity, be different
As huge advance.And for expense, GSM is by Connection Time charging, and GPRS is only needed by data flow meter
Take；GPRS for Internet resources utilization rate and opposite significantly larger than GSM.
Cloud service platform 1 is issued data by internet 5 after modules are by collected finish message
Cloud service platform 1, cloud service platform 1 carry out data process&analysis, so after receiving the data that modules transmit
After send data to air filter control module 41, tunnel lamp control module 42, road information display screen control module 43,
Early warning is provided to driving driver when vehicle passes through.
Obviously, described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all
Other embodiments shall fall within the protection scope of the present invention.
