Description
Technical field
The present invention relates to computer technology, specifically a kind of parameter limit terminal.
Background technology
It is serious problems of puzzlement research and development of products enterprise that terminal device is illegally copied by other people, in order to prevent terminal device, illegally copied problem, be generally the encryption chip that increases CPU in terminal device at present, but this method need increase higher element expense and security and not high flexibly.
Summary of the invention
The object of the invention is to overcome the deficiency of prior art scheme, and propose a kind of parameter limit terminal.
The said terminal device operation parameter of this instructions comprises application content data or the workload data of time data or printing.
Parameter authentication terminal is preset when operation parameter reaches restrictive condition cisco unity malfunction, only in operation parameter, obtain the basis that the normal program of working of the rear described parameter authentication terminal ability of correction is the technical program, and the each terminal of its correction parameter is not identical.
For reaching the object of the invention, adopt following technical scheme: a kind of parameter limit terminal method, a kind of parameter limit terminal is provided, it is characterized in that:
Parameter authentication terminal is preset when operation parameter reaches condition thresholding cisco unity malfunction, only condition thresholding obtain correct after the program that could normally work of described parameter authentication terminal;
Parameter authentication terminal is constantly collected and is checked described operation parameter again, when the operation parameter of described particular data
During eligible thresholding, just carry out normal work;
Described parameter authentication terminal is accepted the modification of operation parameter, and the operation parameter of upgrading is authenticated.
The poly-explanation 1 of step: parameter authentication terminal is preset when operation parameter reaches condition thresholding cisco unity malfunction, only operation parameter obtain correct after the program that could normally work of described parameter authentication terminal; Normally relevant with the time parameter of operation parameter storing, or the password relevant with the time, or the parameter relevant with the application content data of printing or workload data.Described operation parameter is to receive print data or the machine clock data of printing communication interface, or the machine application content data or workload data; For example setting operation parameter is to make time data can not be greater than 2013()-05(the month)-17(day) during-10()-30(divides), when receiving time data in application content data and be greater than 2013-05-17-10-30 described in terminal device do not carry out printing or other application operating; For example set operation parameter and be the text strings that makes application content data can not have " all correctly completing ", when receiving the text strings that has " all correctly completing " in application content data described in terminal device do not carry out printing or other application operating; For example establish again operation parameter and be the workload counter data value that page prints and can not be greater than 10,000 pages, when the workload data counter value of printing when page is greater than 10,000 described in terminal device do not carry out printing or other application operating; These specific limit functions are realized by CPU application software.When the follow procedure method of making an appointment changes above-mentioned setting operation parameter into 2018()-05(the month)-17(day) during-10()-30(divides) after, this terminal can have been worked again the longer time.
The poly-explanation 2 of step: described parameter authentication terminal is constantly collected and checked described operation parameter again, i.e. cumulative sum note
The operation parameter that record occurs could normally be worked when the eligible thresholding of operation parameter of described particular data.
The poly-explanation 3 of step: the modification that described parameter authentication terminal is accepted operation parameter stores, so that legal terminal is obtaining after correct operation parameter is upgraded and can normally work down; But described parameter authentication terminal can be entered deciphering and authentication processing to the operation parameter of upgrading, and prevents from illegally upgrading operation parameter.
See Fig. 1, a kind of parameter limit terminal, comprises embedded type CPU, and described CPU comprises application apparatus and parameter limit treating apparatus, it is characterized in that described parameter limit treating apparatus also comprise again be in order connected as lower device:
For upgrading the device 1 of operation parameter condition thresholding;
For receiving the device 2 of application data;
For analyzing the particular data that receives described application data, when the operation parameter symbol of described particular data
While closing condition thresholding, just carry out the device 3 of normal work.
The machine application apparatus is the special function being realized by CPU software, for example printer function, cashing machine function, Presentation Function etc.Described application data is for example the content-data of printing or the content-data of demonstration etc.
Described application apparatus comprises printing equipment or display device or communication interface or key board unit.
Device 1 explanation: upgrade normally relevant with the time operation parameter of operation parameter condition thresholding, or the operation parameter relevant with the application content data of printing or workload data, and the operation parameter of encryption can be decrypted and authenticate.
Device 2 explanations: for example receive print data or the machine clock data of printing communication interface, or the machine application content data or workload data.
Device 3 explanations: for example setting operation parameter is to make time data can not be greater than 2013()-05(the month)-17(day) during-10()-30(divides), when receiving time data in application content data and be greater than 2013-05-17-10-30 described in terminal device do not carry out printing or other application operating; For example set operation parameter and be the text strings that makes application content data can not have " all correctly completing ", when receiving the text strings that has " all correctly completing " in application content data described in terminal device do not carry out printing or other application operating; For example establish again limiting parameter and be the workload counter data value that page prints and can not be greater than 10,000 pages, when the workload data counter value of printing when page is greater than 10,000 described in terminal device do not carry out printing or other application operating; These specific limit functions are realized by CPU application software.When the follow procedure method of making an appointment changes above-mentioned setting operation parameter into 2018()-05(the month)-17(day) during-10()-30(divides) after, this terminal can have been worked again the longer time.
See Fig. 1, a kind of parameter limit terminal, comprises embedded type CPU, and described CPU comprises the machine application apparatus and parameter limit treating apparatus, it is characterized in that described parameter limit treating apparatus also comprises again the functional module being connected in order:
For upgrading the functional module 1 of operation parameter condition thresholding;
For receiving the functional module 2 of application data;
For analyzing the particular data that receives described application data, when the operation parameter symbol of described particular data
While closing condition thresholding, just carry out the functional module 3 of normal work.
The functional module 1-3 explanation that the parameter limit treating apparatus of described a kind of parameter limit terminal comprises is identical with the device 1-3 explanation of above-mentioned parameter limiting terminal.
Above-mentioned parameter restriction treating apparatus is realized by described cpu system program, and software flow is shown in Fig. 2.
The present invention compared with prior art, has following advantage and effect: the illegal use problem that has solved imitated terminal with low cost.
accompanying drawing explanation:
