Abstract
The utility model discloses an encryption type DTU (Date Transfer unit) module capable of performing external programming, belonging to a DTU module in the tax control industry and comprises a CPU control module and a power supply module; the power supply module is in connection with the CPU control module. The encryption type DTU module also comprises an encryption USBKey module and a wireless module which are both in connection with the CPU control module. The wireless module is an SIM800 module. Compared with prior arts, the encryption type DTU module capable of performing external programming realizes private network access and data cryptograph wireless transmission and has the characteristics of stable performance and low manufacture costs.
Description
Technical field
The utility model relates to a kind of DTU module of tax control industry, specifically a kind of ciphering type DTU module that can outside programming.
Background technology
In current tax control field, more and more higher for the demand that data security is transmitted and long distance wireless is declared dutiable goods, but at present based on tax control machine and mode wireless, encrypting module, stability is low, complex operation, and cost cost height.
DTU, English full name Data Transfer unit is translated as data transmission unit.Be to be specifically designed to serial data is converted to the IP data or the IP data are converted to the wireless terminal device that serial data transmits by cordless communication network.
USB Key is a kind of hardware device of USB interface.Its built-in single-chip microcomputer or intelligent card chip has certain storage space, can store user's private key and digital certificate, utilizes the built-in public key algorithm realization of USB Key to the authentication of user identity.Because private key for user is kept in the coded lock, make in theory in any way and all can't read, therefore guaranteed user's authenticating safety.
The utility model content
Technical assignment of the present utility model is at above weak point, provides a kind of and has realized private network access, data ciphertext wireless transmission, and stable performance, a kind of ciphering type DTU module that can outside programming that the cost cost is low.
The technical scheme that its technical matters that solves the utility model adopts is: comprise CPU control module, power module, power module connects the CPU control module, also comprise and encrypt USB Key module, wireless module, encrypt USB Key module and wireless module and all be connected to the CPU control module.
Wireless module is the SIM800 module.
A kind of ciphering type DTU module that can outside programming of the present utility model uses step to be: 1, by USB mouth or serial ports the utility model to be connected to PC, to connect the external power supply of power module, power on to the utility model; 2, install the DTU terminal software and open at PC; 3, by PC end DTU terminal software dialing parameters, server parameter etc. are set, carry out dial-up connection; 4, PC is passed to the utility model with tax-control data, and ciphertext is carried out and encrypt, generated to encryption USB Key module of the present utility model, and ciphertext is passed to background server by the wireless network of wireless module and handled; 5, background server returns to the utility model with result, returns to PC after the utility model deciphering.
PC end DTU terminal software makes and encrypts USB Key module realization data encryption processing, realizes that the ciphertext of encrypting USB Key module generates, PC end DTU terminal software has been realized dialing control, the data transmission of wireless module, wireless module is realized the private network data transmission of the utility model and background server, and carries out the outside programming by PC as required.
A kind of can outside ciphering type DTU module of programming comparing with prior art of the present utility model has the following advantages:
1, carries out safe teledata encrypted transmission, realize that the wireless remote of tax-control data is sent a duplicate in real time;
2, can carry out outside programming Control as required, satisfy user's demand, thereby, have good value for applications.
