Description
Technical field
The utility model relates to GPRS field of wireless, specifically a kind of data transmission module based on GPRS network.
Background technology
Nowadays, in the numerous areas such as intelligent grid, Smart Home, remote monitoring, data acquisition and Internet of Things, one that faces real problem is: the often independent and scattered distribution of collecting device in the entire system, is a difficult problem for more complicated to the remote transmission of these device data safety and stability always.All the time, the technology of carrying out data remote transmission about means such as adopting optical cable, ultrashort wave, power line carrier, satellite communication is also in the exploratory stage, but as a whole, because of capital intensive, the reason such as conditional request is harsh, utilization rate of equipment and installations is low, above-mentioned technological means just uses in the field of relative narrower, cannot the carrying out of versatility promote, remote data communication problem becomes the development bottleneck restricting whole field.
General packet radio service gprs (General Packet Radio Service) is the carrying of a kind of packet-switched data and transmission means that grow up on GSM basis, provides end to end, the wireless IP of wide area connects.It breaches GSM net can only provide the Circuit-switched mode of thinking, only realize packet switching by increasing corresponding functional entity and carrying out part transformation to existing base station system, the input of this transformation is also little comparatively speaking, but the user data rate obtained is considerable.
Along with logical GPRS network, oneself becomes the resource of a kind of sustainable use and exploitation, be that the GPRS communication of carrier obtains applying more and more widely with embedded system, the feature of its " always online; access speed is fast; to adopt data traffic charging way ", there is unrivaled superiority of effectiveness, be specially adapted to the remote transmission market demand of the industries such as Automation of Electric Systems, industrial monitoring, environmental monitoring, intelligent grid.How the GPRS wireless network that utilizes of efficient stable completes the task of remote data transmission, to the actual meaning that solves practical problems.
Utility model content
The utility model provides a kind of data transmission module based on GPRS network, take full advantage of GPRS network environment broad covered area, characteristic that cost performance is high, need not again build or buy the extra network facilities, the GPRS wireless network that utilizes of efficient stable realizes the task of collecting device remote data transmission.
The utility model is by the following technical solutions: based on the data transmission module of GPRS network, it is characterized in that, comprise control module, memory module, communication module, external interface module and power module, described power module is all modules with power supplies; Described control module is LPC1768 chip; Described memory module is ROM, and described ROM is connected with control module; The Uart interface of described external interface model calling control module; Described communication module comprises GPRS module and some sim card slots, and described some sim card slots are connected in GPRS module, the Uart interface of described GPRS module link control module.
Further, described communication module also comprises signal and strengthens antenna, and described signal strengthens antenna and connects GPRS module.
Preferably, described GPRS module adopts M590 chip.
The beneficial effects of the utility model are:
1, external interface module is provided with, can compatible multiple interfaces for external devices, can external multiple collecting device.
2, be connected with GPRS module by the multiple sim card slot of design, can the data communication of indifference process and multiple business's SIM card that communicates.

Principle schematic when Fig. 2 is the utility model use.
Embodiment
As shown in Figure 1 based on the data transmission module of GPRS network, comprise control module, memory module, communication module, external interface module and power module, wherein, described power module is all modules with power supplies.
Described control module is the LPC1768 series microprocessor of ARM Cortex-m3 kernel, the function of main program execution and Control on Communication and responsible data operation is carried out in whole system is run, its operation result can be sent to memory module as required and preserve, or sends to communication module to send; Described memory module is ROM, carries out the storage of parameter and data, and described ROM is connected with control module; The Uart interface of described external interface model calling control module, this module and outside can be made to carry out data communication, and external interface is compatible plurality of devices interface in form; Described communication module comprises signal and strengthens antenna, GPRS module and some sim card slots, GPRS module adopts the GSM/GPRS wireless industrial module M590 chip of Dual Band, described signal strengthens antenna and connects GPRS module, described some sim card slots are connected in GPRS module, can the data communication of indifference process and multiple business's SIM card that communicates, the Uart interface of described GPRS module link control module.
When specifically using, as shown in Figure 2, this module is arranged on collecting device, utilize the data acquisition port of external interface model calling collecting device, according to the quality of local communications service provider, select the sim card insertion sim card slot that suitable, just be connected in GPRS network when collecting device powers on, using GPRS network as Wireless Data Transmission platform, set up the communication link with data center simultaneously, for real-time reception and the transmission of device data, essence is exactly that data acquisition equipment and data center are linked into the remote transparent transmission realizing final image data in GPRS network platform.
Except structure described in the utility model, all the other are prior art.
The above is preferred implementation of the present utility model; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications are also regarded as protection range of the present utility model.
