Description of drawings
Fig. 1 is the access terminal structure principle chart of embodiment of new type of safe that the utility model is built-in with the GPRS communication module.
Embodiment
Below in conjunction with accompanying drawing the new type of safe of the GPRS of being built-in with communication module of the present utility model is accessed terminal to do in further detail and describe.
As shown in Figure 1, the safety that has the GPRS communication module in this example accesses terminal, and comprises power module, interface module, encryption chip, central processing unit and is embedded with the GPRS communication module of ICP/IP protocol stack.The below describes each parts of this terminal respectively:
Central processing unit: be the vitals of this terminal, can adopt ARM7 series flush bonding processor, the main scheduling of being responsible for whole control and data.Can in central processing unit, embed authentication module, before the enciphered data that first serial is sent by GPRS communication module reception external server, external server is carried out authentication, checking receives enciphered data, the fail safe that can improve transfer of data by the GPRS communication module again by rear first serial.
Power module: can adopt the external power supply of 3.3V, be responsible for central processing unit, interface module and encryption chip working power is provided, the 3.3V external power supply is installed in cabinet inside by the power interface that is arranged on case front panel or backboard place.
Interface module: comprise power interface, first serial and second serial, first serial is embedded with the ICP/IP protocol stack, and the ICP/IP protocol stack mainly is responsible for packing the data to network packet, to realize the transparent transmission of data between external server and the communication terminal.The TCP/IP ICP/IP protocol is called transmission control/Internet protocol, and it is the basis of Internet Internet, is the basic communication agreement of using in the network, and the ICP/IP protocol stack is the protocol groups that a cover gets up the various system interconnections on the internet.The BTU of ICP/IP protocol is packet (datagram), Transmission Control Protocol is responsible for data are divided into several packets, and add packet header (just as adding envelope to an envelope letter) for each packet, corresponding numbering is arranged on the packet header, to guarantee data to be reduced to original form at data receiver, the IP agreement is added the receiving terminal host address in each packet header, data find the place that oneself will go like this, if occur loss of data in the transmission course, the situations such as data distortion, Transmission Control Protocol can require data again to transmit automatically, and re-groups package.In a word, the IP agreement guarantees data transfer, and Transmission Control Protocol guarantees the quality of transfer of data.The ICP/IP protocol data transfer is based on the four-layer structure of ICP/IP protocol: application layer, transport layer, network layer, interface layer, data whenever will add a packet header in data by one deck when transmission, data wherein are for receiving terminal same layer agreement, and at receiving terminal, every process one deck will removing with the packet header of crossing, guarantee that like this form of the transmission of data is in full accord.
Encryption chip has the functions such as encryption, deciphering, signature, sign test, and is used for preserving key information, supports the cryptographic algorithm of RSA, AES, SHA1, SM1, the many generals such as SM2, SM3.
In order to make terminal more neat and artistic, this terminal can also have a cabinet, and this cabinet adopts metal material, and it is dustproof to discharge water, the support bracket fastened installation such as guide rail support.Above-mentioned central processing unit, power module and encryption chip are installed on cabinet inside and (for example in the case back plate inboard draw-in groove are set, central processing unit, power module and encryption chip are fixedly arranged on respectively in the draw-in groove of backboard), power interface, first serial and second serial can be installed on the front panel of cabinet, also can be installed on the backboard of cabinet.In order to understand more easily this terminal operating status, can various indicator lights be installed at the cabinet outer surface, comprising: the power supply indicator that is connected with power module and the transfer of data indicator light and the running LED that are connected with central processing unit.
Before use, connect by first serial and the external server (for example PC) of GPRS communication module with this terminal first, then power line and the Transistor-Transistor Logic level rs 232 serial interface signal line of drawing in the power interface of this terminal and second serial and the communication terminal device (for example computer or mobile phone) connected, this moment, power supply indicator was lighted, and showed that this terminal can work.The first serial of this terminal receives the enciphered data come from external server by the GPRS communication module, and is sent to second serial after being decrypted through encryption chip, reaches communication terminal device by second serial; The data that communication terminal device sends reach encryption chip through second serial and are encrypted, and are issued to external server by the GPRS communication module again.
Therefore, the new type of safe of the GPRS of being built-in with communication module of the present utility model accesses terminal and can embody the human oriented design of product, can satisfy the client to the demand of terminal security protection, thereby the self-value of product is provided, and has and promotes widely and practicality.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; in conjunction with above-described embodiment the utility model is had been described in detail; those of ordinary skill in the field are to be understood that: those skilled in the art still can make amendment or are equal to replacement embodiment of the present utility model, but these modifications or change are all among the claim protection range that application is awaited the reply.
