It is transmitted according to Wiegand protocol for Card Reader information, that is, obtains the corresponding Card Reader information correspondence sent under Wiegand protocol
Card number digit.For example, in general, binary number of 4 digits can represent the unitss under a decimal scale, and
The Card Reader information transmitted under Wiegand protocol is the binary array represented with " 0 " and " 1 ", according to binary array
The card number digit included in digit, it may be determined that the digit of the array under corresponding decimal scale, as Card Reader information.
Further, in the present embodiment, card number character string as by the containing of reader device transmission " 0 " and
The character string of " 1 ", after the Card Reader information for obtaining access card, obtains the card number character string included in Card Reader information.
Step S106：Wiegand form conduct corresponding with the card number digit is searched in default Wiegand form database
Target Wiegand form.
It should be noted that in the present embodiment, management terminal needs to carry out corresponding Wei for reader device in advance
The configuration of root form, specifically, in the present embodiment, said method also includes：The Wiegand form for receiving management terminal transmission is matched somebody with somebody
Put instruction；Obtain the Wiegand form that includes in the Wiegand form configuration-direct and store to the Wiegand form database.
User can carry out the relevant configuration of Wiegand form in management terminal to reader device, in the present embodiment
Red, Wiegand form can be made up of following 5 part：Parity check bit, region-position code (SITE CODE), CID (card number), equipment generation
Code (Facility CODE) and vendor code (Manufactory CODE), naturally it is also possible to arrange by above-mentioned 5 part
Part constitutes, and for example, can arrange Wiegand form and only include two parts of region-position code and card number.
User needs the Wiegand to being supported during the Wiegand form supported reader device is configured
The digit of form is determined, and determines above-mentioned parity check bit, region-position code (SITE CODE), CID (card number), equipment generation
Code (Facility CODE) and vendor code (Manufactory CODE) etc. parts are shared specific in Wiegand form
Position, for example, in wiegand26, odd parity bit is the 1st, and even parity bit is the 14th, and card number is 2-13 and 15-
26.That is, including in the configuring request for the Wiegand form of reader device that is input in management terminal of user
Need the digit and corresponding arrange parameter of the Wiegand form of configuration, management terminal receive user input request it
Afterwards, corresponding Wiegand form configuration-direct is generated according to the request and is sent to reader device.
Reader device is matched somebody with somebody after the Wiegand form configuration-direct for receiving management terminal transmission according to the Wiegand form
Putting instruction carries out the configuration of correlation, and the Wiegand form that will be included in Wiegand form configuration-direct and the configuration parameter of correlation are protected
In there is Wiegand form database, for using during follow-up Card Reader and card number checking.
Because the Wiegand form that reader device is supported and corresponding digit are stored in Wiegand form database,
After Card Reader information and card number digit, card number character string is got, it is possible to determine the access card according to corresponding flow process
Corresponding specific Wiegand form, in the present embodiment, the Wiegand form is target Wiegand form, and target Wiegand form with
Access card is corresponding.
In the present embodiment, in various Wiegand forms that reader device is supported, each Wiegand form correspondence one
Individual corresponding card number digit, for example, the corresponding card number digits of Wiegand form wiegand26 are 26, Wiegand form wiegand64 pair
The card number digit answered is 64.
It should be noted that in one embodiment, management terminal is configuring corresponding Wiegand form to reader device
During, the Wiegand form that can be arranged under each unitss can only configure one kind, that is to say, that under same card number digit
Wiegand form only exists one kind, for example, it is impossible to while supporting two kinds of Wiegand forms of wiegand26 and wiegand26a.Here
Kind in the case of, according to the card number digit included in Card Reader information can determine that target Wiegand form and with the target Wiegand form
Corresponding related parameter setting etc..
Optionally, in another embodiment, management terminal is configuring the mistake of corresponding Wiegand form to reader device
Cheng Zhong, can configure multiple with the Wiegand form under one digit number, and can pass through between card number digit identical Wiegand form
Region-position code is making a distinction.
Specifically, the card number character string of the access card contains region-position code information and card number information；It is described default
The step of Wiegand form corresponding with the card number digit is searched in Wiegand form database as target Wiegand form is specially：
Wiegand form corresponding with the card number digit is searched in the default Wiegand form database, if finding, is obtained
At least one Wiegand form for finding alternately Wiegand form；The region-position code is determined according to the card number character string
Information；Target region-position code corresponding with the region-position code information is obtained, is determined and the target in the alternative Wiegand form
The Wiegand form of region-position code matching is used as target Wiegand form.
That is, the Wiegand form under same card number digit potentially included it is multiple, it is determined that corresponding with access card
Target Wiegand form during, it is necessary first to it is determined that the Wiegand form of configuration corresponding with card number digit include which,
Target Wiegand form is included in above-mentioned Wiegand form, in the present embodiment, by what is found in Wiegand form database
Wiegand form corresponding with card number digit alternately Wiegand form.
After alternative Wiegand form determines, it is possible to further to determine target Wiegand form.If alternative Wiegand form
Only one of which, then the alternative Wiegand form is exactly target Wiegand form.If alternative Wiegand form more than one, such as three, then
It is accomplished by further determining target Wiegand form in alternative Wiegand form.In the present embodiment, card number digit identical Wiegand
Can be made a distinction by region-position code between form, that is to say, that if carrying out the mistake of the configuration of Wiegand form in management terminal
Cheng Zhong, is configured with multiple Wiegand forms under same card number digit, just must be provided with corresponding Wiegand form and supports region-position code
Checking, and be by the different making a distinction of region-position code between Wiegand form and Wiegand form.
In the parameter setting of Wiegand form, the digit of the corresponding region-position code of multiple Wiegand forms under same card number digit
It is certain, that is to say, that the character string of corresponding position and digit directly can be read in card number character string, and is carried out
Parsing, what is obtained is the corresponding region-position code of the access card.
Step S108：Card Reader information is parsed according to the target Wiegand form, is obtained and the Card Reader information pair
The target card number answered.
As it was previously stated, during management terminal carries out the configuration of Wiegand form to reader device, for each
The Wiegand form of configuration, can arrange the corresponding setting rule of its corresponding region-position code, card number, parity check bit, therefore, at this
In embodiment, known to target Wiegand form and Card Reader information it is also known that in the case of, according to corresponding with the target Wiegand form
Related region-position code, card number, parity check bit are isoparametric arranges rule, it may be determined that each included in Card Reader information
Corresponding concrete meaning.Further, according to card number analytic method corresponding with the target Wiegand form, Wiegand protocol is issued
The Card Reader information sent is parsed, and is obtained and is parsed the information for obtaining as target card number.It should be noted that in the present embodiment
In, target card number refers to the related data represented with binary system or " 0 " and " 1 " under non-Wiegand protocol, but to commonly use
The card number information that metric form shows, as target card number.
Further, in the present embodiment, before target card number is parsed, not only need to carry out school to region-position code
Test, in addition it is also necessary to which parity bit is verified.
Specifically, in general, odd even bit check is it is determined that before target Wiegand form, being sent to check
Card Reader information in the phenomenon lost with the presence or absence of information of the card number character string that includes.Specifically, the above-mentioned acquisition Card Reader letter
Also include after the step of card number digit and card number character string of breath：Even-odd check is carried out to the card number character string, if school
Test and pass through, then Wiegand form conduct corresponding with the card number digit is searched in default Wiegand form database described in execution
The step of target Wiegand form, if verification does not pass through, generate the information of authentication failed.
According to the setting of specific position of the default parity bit check code in card number, in obtaining the card number character string
Odd parity bit and even parity bit, and carry out corresponding even-odd check, and obtain the result of corresponding even-odd check.In this reality
In applying example, only in the case where even-odd check passes through, just proceed other verifications, such as position code check etc. is otherwise tested
Card does not pass through, and generates corresponding prompting message and show user.
It should be noted that in the present embodiment, when the checking message of verification failure is shown, the content of displaying not only may be used
Including the result of authentication failed, can also include the principle of authentication failed, for example, even-odd check failure or position code check lose
Lose.
Further, in the present embodiment, user, can be with during the design parameter for arranging Wiegand form is arranged
Card number reversion is arranged to the card number of Wiegand form, that is to say, that during parsing to card number, it is necessary to which card number is carried out
Reversion can just obtain final correct card number, so as to improve the safety of corresponding card number checking.
Specifically, it is above-mentioned the step of parsed to the card number character string according to the target Wiegand form before also wrap
Include：Determine whether the target Wiegand form is provided with card number reversion, if so, then the card number character string inverted and incite somebody to action
The character string that obtains of inverting as card number character string, and perform it is described according to the target Wiegand form to the card number word
The step of symbol string is parsed.
