The corresponding expanded function code of expanded function of the transmitter opened, generation is described to open key.Wherein,
The string number is unique and is described on every shell of transmitter for every transmitter
Label.As described above, the string information of transmitter can also other modes enable the user of transmitter
Enough know, will not be repeated here.In further embodiment, methods described 200 also includes logical
Any one mode crossed in the following manner obtains the string number of transmitter 1010 and expects the transmitter opened
1010 expanded function：Phone, fax, short message, mail, filled in by website and combinations thereof.
In step 2020, key is opened in input.Specifically, it is open-minded by what is generated in step 2010
Key input transducer 1010.In a preferred embodiment, before step 2020, methods described
200 also include in the following manner in any one mode obtain and described open key：Phone, fax,
Short message, mail, by website leave a message and combinations thereof.
In step 2030, compare and open key and refer to key.Specifically, key is opened by described
It is compared with reference to key, judgement opens whether key matches with reference to key.
In step 2040, when it is described open key with the reference cipher key match when, open the phase
The expanded function of the transmitter 1010 that prestige is opened.
Under typical application scenarios, the user of transmitter is wishing to open the expanded function of its transmitter
When, contact staff can be contacted with modes such as phone, fax, short message, mail or its combinations, inform
The expanded function of the transmitter that the string number of its transmitter and expectation are opened.In generation and the string number of transmitter
It is corresponding with the expanded function of transmitter for expecting to open, unique open key after, contact staff
The key of opening that be able to will be generated by modes such as phone, fax, short message, mail or its combinations is carried
Supply the user of transmitter.However, the present invention is not limited in this respect, for example, transmitter makes
User can log in appointed website, voluntarily the expansion of the transmitter that the string number of input transducer and expectation are opened
Exhibition function, and obtain online open expanded function open key.
In a preferred embodiment, the key input transducer 1010 of opening can be included passing through
The host computer of transmitter 1010 will open key input transducer 1010.Wherein, host computer can lead to
Cross wired mode or wireless mode to be communicatively coupled with transmitter 1010, for example, the host computer
Can be communicated with transmitter 1010 by RS485 or HART communication port.Further preferably real
Apply in mode, host computer can be notebook computer.Those skilled in the art can also basis
It is actually needed by the use of any other suitable electronic equipment as host computer, such as can be with transmitter
1010 mobile phones for being communicated, panel computer etc..
In a preferred embodiment, transmitter 1010 includes at least one register, using upper
In the preferred embodiment of machine, when key is opened with reference to cipher key match, will be opened by host computer
Register corresponding with the expanded function of the transmitter for expecting to open in key write-in transmitter 1010
(not shown).In a preferred embodiment, can complete to open key with reference by transmitter 1010
The comparing operation of key.Those skilled in the art is it is easily understood that can be right according to actual needs
Design of the invention carries out appropriate modification, for example, can complete key by single device comparing
Operate and the device can be communicated with transmitter 1010 and host computer.Additionally, close when opening
When key with reference to key with mismatching, corresponding prompt message can be provided, such as host computer can be detected
Correspondence register is not successfully written to key is opened, so that point out user authentication failed, this point
Belong to the common knowledge of this area, therefore will not be described here.
Referring now to Fig. 3, Fig. 3 is the schematic diagram according to an embodiment of the invention, is shown
The generating process for opening key of example property.As shown in figure 3, wherein T1The string number of transmitter is represented,
F1、F2……FNRepresent expanded function 1, expanded function 2 ... expanded function respectively with transmitter
The corresponding expanded function codes of N, K11、F12……K1NRepresent generation opens key.
When wishing to open string number for T1Transmitter expanded function 1 when, by the string T of transmitter1
And expanded function code F1 corresponding with the expanded function 1 is together as the defeated of key generating device
Enter, key generating device is based on T1And F1What the expanded function 1 was opened in generation opens key K11。
Similarly, when wishing to open expanded function N, by the string T of transmitter1And with the extension work(
The corresponding extensions of energy N being capable of code FNTogether as the input of key generating device, key generation dress
Put based on TNAnd FNWhat expanded function N was opened in generation opens key K1N。
It is easily understood that under foregoing typical application scenarios, the user of transmitter can be simultaneously
Multiple expanded functions of the transmitter that the string number of contact staff its transmitter and expecting is opened are informed, or
Online input string number and multiple expanded function codes, the mistake of key is opened for the generation of each expanded function
Journey is generated as key using the string number of transmitter expanded function code corresponding with the expanded function
The input of device opens key accordingly to generate.
In the present invention, expanded function code corresponding with the expanded function of transmitter is to be readily available
, for example, expanded function code can be documented on product description or user's manual, Huo Zheke
Inquired about with by website.Those skilled in the art is contemplated that various other modes come before providing
Expanded function code is stated, the present invention is unrestricted in this regard.
The different extension work(according to different transmitters can be realized using system and method for the invention
Dynamic calculates one-to-one key to open corresponding expanded function, so as to improve the secrecy of product
Property, it is provided simultaneously with good operability.In other words, change can both be protected by design of the invention
Send the expanded function of device to open authority, can open expanded function in site of deployment again, combine product
Encryption and good operability.
