Abstract
A remote data transmission device comprises a power supply module, a wireless transmission module, a Flash, a memory, peripheral interfaces and a CPU. Only one CPU is included, and the wireless transmission module, the Flash, the memory and the peripheral interfaces are all connected with the CPU. The peripheral interfaces include an analog interface and a digital interface, and the CPU internally comprises a control unit of the wireless transmission module. The internal CPU resource of the wireless transmission module of a conventional remote data transmission device is fully utilized, peripheral CPU, Flash and memory can be omitted, and functions of the peripheral CPU are all realized by the CPU in the wireless transmission module, thereby simplifying system hardware design, reducing the cost of hardware design, and providing system stability.
Description
Technical field
The utility model relates to electronic applications, relates in particular to a kind of device with remote data transmission function.
Background technology
After first gsm module commercialization in 1993, GSM is used widely in M2M industry till now, and particularly since State Council's abstract networking strategy in 2009, GSM is at electricity meter-reading, GPS navigation, and base station monitoring industry is greatly developed.But due to project the pursuit of time effect, the product of each Corporation R & D all do not focus on cost consideration, and exploitation of the residue data of core controller and the kernel of gsm module own in product.Current remote data transmission device is all the technical scheme that adopts CPU+GSM module, is connected, and operates gsm module by AT order between CPU and GSM by serial ports.And realize remote data transmission, gsm module itself is an independently system, there are independently MCU, Flash and internal memory, whole remote data transmission device comprises two cpu systems, and CPU accounts for very large ratio in the cost of whole device, the production technology of two systems is also more complicated simultaneously, and processing cost is also higher, so this device exists the problem that cost is high; Owing to there are two cpu systems simultaneously, data communication also needs to communicate by external bus, as long as there therefore have a system to exist to be unstable, that whole device is also unstable, so the not high problem of resistance to overturning of this device existence.
Summary of the invention
Technical problem to be solved in the utility model is how to provide a kind of with low cost and system stability, the device with remote data transmission function that extensibility is strong.
In order to achieve the above object, the utility model has designed a kind of remote data transmission device, comprise power module, wireless transport module, Flash, internal memory, Peripheral Interface and CPU, it is characterized in that only comprising a CPU, described wireless transport module, Flash, internal memory are all connected with described CPU with Peripheral Interface, described Peripheral Interface comprises analog interface and digital interface, and described CPU inside comprises the control unit of wireless transport module.
Described remote data transmission device, is characterized in that described wireless transport module is GSM radio-frequency module, 3G radio-frequency module, 4G radio-frequency module or WiFi module.
Described remote data transmission device, also comprises SIM card card reading module, and described SIM card card reading module comprises card reading circuit and deck, and described card reading circuit is connected with CPU.
Described remote data transmission device, is characterized in that described CPU inside comprises built-in A/D module.
Described remote data transmission device, characterized by further comprising and extend out A/D module.
Described remote data transmission device, is characterized in that described digital interface is serial ports, USB mouth and/or network interface.
Described remote data transmission device, characterized by further comprising human-computer interaction module, and described human-computer interaction module comprises keyboard input module and/or Led display module.
Enforcement the utlity model has following beneficial effect: of the present utility model by making full use of the cpu resource of the wireless transport module inside of existing remote data transmission device, in device, can save CPU, Flash and the internal memory extending out simultaneously, the function that all CPU of extending out realize is all realized by the CPU of wireless transport module inside, simplified the Hardware Design and cost, the stability of system is also provided simultaneously.
Accompanying drawing explanation
Fig. 1 is the system block diagram of remote data transmission device.
the concrete example of implementing
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the system block diagram of remote data transmission device, comprises power module, wireless transport module, Flash, internal memory, CPU, SIM card card reading module, serial ports, USB mouth, network interface, keyboard input module and Led display module.
Specific implementation is selected the Q2687 wireless module of WAVECOM company, and the Flash of the CPU of the ARM chip that described Q2687 module contains 32-bit, 64M bit size and the internal memory of 32M bit size, directly save the CPU, internal memory and the Flash that extend out.The GSM radio-frequency module that wireless transport module selects former module to carry, serial ports, USB mouth, network interface, keyboard input module and Led display module are connected with CPU.
By SIM card card reading module, can realize the data of SIM card are read, realize control and the identification of GSM identity, and then realize recognition of devices and the control of remote data transmission device.
Remote data transmission device can complete and the communicating by letter of subscriber's local equipment by serial ports, USB mouth or network interface, local device can pass through serial ports, USB mouth or network interface and control remote data transmission device, the data of required transmission or instruction are input to remote data transmission device by these interfaces simultaneously, remote data transmission device transmits data or instruction by wireless transport module to remote equipment, realize remote data transmission function.
Consider the diversity of the interface of subscriber equipment, serial communication circuit is designed to compatible three level TTL 232 and 485 circuit criteria.
Above disclosed is only a kind of embodiment of the utility model, certainly can not limit with this interest field of the utility model, one of ordinary skill in the art will appreciate that all or part of flow process that realizes above-described embodiment, and the equivalent variations of doing according to the utility model claim or meet the added part adjunct circuit of different application, still belong to the scope that utility model contains.
