Below by preference, the present invention is more specifically illustrated:
Embodiment 1:
A kind of wireless data transmission device based on GPRS is grown up on the basis of existing gsm mobile communication system
A kind of mobile pocket data business.GPRS by GSM digital mobile communication network introduce packet switch functional entity,
It is transmitted with completion with the data that packet mode carries out.
One-chip computer module: the data that docking is come are sorted out, and compare with the data of standard, will be overproof
Data screening comes out.
GPRS module: data processing can be carried out rapidly, reports the data transmission that one-chip computer module screens.
SIM card holder module: being connected with GPRS module, built-in SIM card.
External interface module: including USB interface, antennal interface and power interface.
Memory module: the data that docking is come temporarily are stored, and one-chip computer module is facilitated to carry out screening operation.
As shown in Figure 1, a kind of wireless data transmission device based on GPRS is mainly by single-chip microcontroller, the GPRS of insertion TCP/IP
Module, SIM card holder, external interface and memory portion composition.Single-chip microcontroller control GPRS module sends and receivees information, passes through string
Mouth circuit and peripheral control unit (such as data collection terminal) carry out data communication.
One-chip computer module supports serial and concurrent in-system programming.Double Data pointer DPTR0 and DPTR1 can accelerate data
The movement speed of block.It mainly realizes that process is as follows: instructing initialization GPRS wireless module by AT, is allowed to be attached to GPSR net
On network, the GPRS IP address of terminal that network operator dynamically distributes is obtained, and establish connection with purpose terminal.
Standard serial port and peripheral control unit are simultaneously not belonging to this set system, this set system is only merely data transmission.And lead to
Cross that standard serial port and peripheral control unit illustrate is how to acquire and obtain data.
It is connected by standard serial port and peripheral control unit (such as data collection terminal), peripheral control unit terminates out standard string
Mouthful, it is communicated according to the controller that the agreement made an appointment can be readily available the design.Memory can be all as Flash program
Memory or all as data Flash program.Because being embedded in real time operating system and network protocol, certain sky is needed
Between.Radio receiving transmitting module of the GPRS wireless module as terminal, point that the IP packet sended over from single-chip microcontroller or base station are transmitted
Group data forward again after performing corresponding processing.
GPRS wireless module is mainly by radio-frequency antenna, inside Flash, SRAM, GSM baseband processor, matching power supply and one
The ZIF socket of a 40 foot forms.GSM baseband processor is core component, a protocol processor is functioned as, for locating
It manages external system and AT instruction is sent by serial ports.Mainly realize that the modulation and demodulation of signal and outside are penetrated in radio-frequency antenna part
Signal between frequency signal and internal baseband processor is converted.It matches power supply and provides required electricity for processor base radio frequency part
Source.
ICP/IP protocol is not supported based on GPRS module used in GPRS network application system, in order to work identical
On network level, the data of internal transmission must will use identical agreement, so in addition to the function using GPRS module
Outside, the program by TCP/IP and ppp protocol Standard compilation is also embedded in SCM system, to enable the terminal device of design
It is enough easily to apply GPRS data Packet Service.ICP/IP protocol is a standard agreement external member, is described with hierarchical mode.Number
When according to being packaged processing data, each layer is added to the information of oneself in one data head, and this data head is by next layer
In agreement be packaged into data volume.When data solution packet handler receives GPRS data, corresponding data head is removed, and
The rest part of data packet is treated as data volume.
Data packet is transmitted in host and GPRS server zone uses IP-based to be grouped, i.e., all data messages
It will be based on IP packet.But transmission IP packet is undesirable in plain text, therefore is transmitted using ppp protocol.Module sends PPP message to gateway
It will be transmitted to corresponding address in Internet, and the acknowledgement frame sent from Internet similarly can according to IP
Location is transmitted to GPSR module, to realize the transparent transmission that acquisition data and Internet network pass through GPRS module.
