Modern plant device management method based on near-field communication shown in Figure 2, in the embodiment of the present invention, the modern plant equipment management system shown in Fig. 1, should comprise the steps: based on the modern plant device management method of near-field communication

Step 1, gate inhibition's subsystem gathers the work card information of each shop equipment management personnel, ID card information and finger vena information, set up a factory equipment management personnel data base, and as corresponding shop equipment management personnel, each data in shop equipment management personnel data base are entered the authentication information in factory；

Such as, for shop equipment management personnel Zhang San, gate inhibition's subsystem needs to gather the finger vena of the work card number of Zhang San, identity card and Zhang San, thus sets up the authentication information about shop equipment management personnel Zhang San；Same, gate inhibition's subsystem gathers shop equipment management personnel Li Si and the authentication information of other shop equipments management personnel again, and all authentication information of each shop equipment management personnel gathered are stored, thus establishing shop equipment management personnel data base at gate inhibition's subsystem place, in the shop equipment management personnel data base set up, each shop equipment management personnel all correspond to its work card information, ID card information and finger vena information under one's name；Wherein, the name of shop equipment management personnel authentication information above-mentioned with it can be stored in the form of a list in shop equipment management personnel data base；

Step 2, shop equipment management personnel include shop equipment management personnel's information of its work card information, ID card information and finger vena information in the typing in the Intelligent handhold management terminal of NFC function that has allotted of each putting on record, and manage after terminal encryption process through Intelligent handhold, shop equipment management personnel's information that storage gathers manages in terminal to Intelligent handhold；Wherein, this shop equipment management personnel control the lawful owner of the Intelligent handhold management terminal that subsystem is specified for factory, such as, the Intelligent handhold management terminal being numbered 001 and is dispensed to shop equipment management personnel Zhang San after putting on record, then Zhang San is this No. 001 Intelligent handhold and manages the lawful owner of terminal；Accordingly, No. 001 Intelligent handhold manages tag memory and stores up the personal information of its lawful owner Zhang San；Wherein, the process of Intelligent handhold management terminal typing shop equipment management personnel's information comprises the steps 2-1 to step 2-4:

Step 2-1, Intelligent handhold management terminal human magnetic field's data of its lawful owner of Real-time Collection in each preset time period, build this Intelligent handhold and manage the lawful owner of terminal human magnetic field data base in each preset time period, and operate the identity identification information of this Intelligent handhold management terminal using the human magnetic field data base of structure as its lawful owner；Owing to human magnetic field's intensity data is not invariable within each time period, therefore, in the present embodiment, two time periods are pre-set for human magnetic field's data cases, namely the time period preset includes the first preset time period and the second preset time period, and the first preset time period is 06:00 to 18:00；Second preset time period is 18:00 to 06:00 next day；

Step 2-2, Intelligent handhold management terminal gathers the body odour data of its lawful owner, receives the finger vena information corresponding to each finger of its lawful owner, builds Intelligent handhold management terminal lawful owner and savours the venous information data base corresponding to data base and each finger；Owing to everyone body odour is different, it is the same that human body savours the biological characteristics such as the same fingerprint of data, face and iris, it may have unique non-reproduction, therefore the body odour data of human body may also used to the characteristic information as identification；

Intelligent handhold management terminal gives the human magnetic field of its lawful owner and has the first priority when identifying valid operation person's identity, body odour data have the second priority when identifying valid operation person's identity；Wherein, identifying whether operator has in legal identity process, and the first priority has the recognition credibility higher than the second priority；The human magnetic field of the operator namely obtained when Intelligent handhold management terminal judges belongs to the magnetic field data of its lawful owner, and judging when the body odour data obtained are not belonging to the body odour data of its lawful owner, then Intelligent handhold manages terminal and finally judges that operator is its lawful owner；

Step 2-3, Intelligent handhold management terminal touches the current Password Input frame of gate inhibition of display screen display predetermined number to its lawful owner at it, and the current Password Input frame of each gate inhibition correspond to seven kinds of optional base color lists of confession respectively；Wherein, seven kinds of base color in base color list respectively red, orange, yellow, green, cyan, blueness and purple, the current Password Input frame of each gate inhibition correspond to one group of current permission color；The current password of gate inhibition of Intelligent handhold management terminal is its lawful owner current entire combination allowing color of each group of corresponding input in the current Password Input frame of each gate inhibition；The current combination in any allowing color to be described seven kinds of base color of each group；

Such as, Intelligent handhold management terminal touches the current Password Input frame of display 3 gate inhibitions of screen display at it, and gate inhibition passes through Password Input frame numbering 01 input frame, 02 input frame and 03 input frame respectively；Wherein:

01 input frame correspond to redness, orange, yellow, green, cyan, blueness and seven kinds of base color of purple,

02 input frame correspond to redness, orange, yellow, green, cyan, blueness and seven kinds of base color of purple,

03 input frame correspond to redness, orange, yellow, green, cyan, blueness and seven kinds of base color of purple；

The lawful owner of this Intelligent handhold management terminal can at least select a kind of base color as current permission color corresponding to this 01 input frame in 01 input frame, such as, individually select red current to allow color as one group, it is also possible to select red, orange to allow color as corresponding one group of this 01 input frame is current with the combination of yellow these three base color；Similarly, 02 input frame and 03 input frame can also select as required arrange, to form each self-corresponding current permission color；Such as, one group of current permission color that 01 input frame is corresponding is red, red and yellow, one group of current permission color that 02 input frame is corresponding is orange and yellow, one group of current permission color that 03 input frame is corresponding is blue and purple, then the current password of this Intelligent handhold management terminal is the corresponding current entire combination allowing color of each group of three input frames, and namely the current password of Intelligent handhold management terminal is " red, red, yellow；Orange, yellow；Blue, purple ".

Additionally, as a kind of safer gate inhibition's means of defence, the Intelligent handhold management terminal current password at gate inhibition's subsystem place is the current entire combination allowing color of each group that its lawful owner is corresponding in turn to input in the current Password Input frame of each gate inhibition according to sequencing；That is current password is also had restriction effect by the sequencing of various base color, even if the base color in the current color of each group is consistent, but as long as the sequencing of base color input is not right, then can not pass through the certification of gate inhibition's subsystem equally；Such as, the gate inhibition that the lawful owner oneself of Intelligent handhold management terminal sets passes through and allows color as " red, red, yellow；Orange, yellow；Blue, purple ", if having gate inhibition's current permission color that people inputs at gate inhibition's subsystem place is " redness, yellow, redness；Orange, yellow；Blue, purple ", then these personnel can not pass through the certification of gate inhibition's subsystem, and gate inhibition's subsystem will not opening gate；

Owing in the current Password Input frame of each gate inhibition, corresponding each current permission color is lawful owner oneself setting of this Intelligent handhold management terminal, and often the current lawful owner that color is Intelligent handhold management terminal allowed in color of group is arbitrarily randomly provided, therefore final current permission color only has the lawful owner of this Intelligent handhold management terminal to know, other are to be difficult to guess or crack obtain correct current permission color, which thereby enhance the security performance of the current password of Intelligent handhold management terminal, also further enhancing whether entrance personnel are had the certification accuracy rate of legal identity by gate inhibition's subsystem place；

nullStep 2-4，The base color list corresponding according to touching the current Password Input frame of each gate inhibition on display screen，The lawful owner of Intelligent handhold management terminal is selected from the base color combination current permission color respectively as the current Password Input frame of each gate inhibition of definition species number successively，And managed the current permission color corresponding to the terminal current Password Input frame of each gate inhibition of storage corresponding respectively by Intelligent handhold，Then managed terminal by Intelligent handhold and this shop equipment management personnel's authentication information and the current permission color information corresponding with this shop equipment management personnel are sent to the storage of gate inhibition's subsystem，It is authenticated judging with communicating to shop equipment management personnel's identity for gate inhibition's subsystem，And after gate inhibition's subsystem stores Intelligent handhold management terminal transmitted information，Gate inhibition's subsystem generates effective dynamically access key in preset time period and manages terminal to this Intelligent handhold，Terminal identity authentication information when managing terminal using close as its next time for this dynamic access key gate inhibition's subsystem for Intelligent handhold；Wherein, this dynamic access key only allows Intelligent handhold management terminal to use when gate inhibition's subsystem next time；

Such as, the personnel of current handheld Intelligent handhold management terminal have already been through the certification of gate inhibition's subsystem, then now gate inhibition's subsystem generates dynamic access key to this Intelligent handhold management terminal, this dynamic access key that so now Intelligent handhold management terminal receives can only use when next time requires over gate inhibition's subsystem, and this dynamic access key is additionally subjected to preset the restriction of effective time period, once exceed the effective time section preset, even if then this dynamic access key is correct, gate inhibition's subsystem also disapproves the operator of the Intelligent handhold management terminal sending this dynamic access key and passes through gate inhibition, the safety in factory is again ensured that with this, stop non-security, competent person passes through gate inhibition's subsystem；Wherein, gate inhibition's subsystem generates the method for dynamic access key and comprises the steps that (a) is to step (e):

A () gate inhibition subsystem extracts the ID card information of lawful owner corresponding to Intelligent handhold management terminal, and obtain the accumulative and value of the ID card information of all numerals in its ID card information, the meansigma methods of ID card information and ID card information eigenvalue respectively；Wherein:

$X=\underset{i=1}{\overset{m}{\Σ}}{x}_i,Y=\frac{1}{m}\underset{i=1}{\overset{m}{\Σ}}{x}_i,Z=\frac{X}{Y};$

X is the accumulative of ID card information and value, and Y is the meansigma methods of ID card information, and Z is ID card information eigenvalue；x_iFor the i-th digital in identity card, m is the number of all numerals in ID card information；Such as, corresponding to Intelligent handhold management terminal, 18 ID card informations of lawful owner Zhang San include 17 bit digital and an alphabetical X, then corresponding in above-mentioned information m=17；Owing to everyone ID card information is unique, then in this step (a), calculated accumulation and value, ID card information meansigma methods and ID card information eigenvalue are also unique, such that it is able to each corresponding numerical value of gained is as the eigenvalue of identification, avoid other unauthorized person forged identity information, illegally to pass through gate inhibition；

B (), according to the accumulative of the ID card information obtained and value, meansigma methods and ID card information eigenvalue, obtains the effective first dynamic key value in preset time period；Wherein, the first dynamic key value is labeled as k, and the first dynamic key value k is obtained by equation below:

k³=Xt²+ Yt+Z, t ∈ [T₁,T₂]；

T is the time value that gate inhibition's subsystem receives Intelligent handhold management the sent information of terminal, T₁For the initial time of the preset time period of dynamic access key, T₂End time for the preset time period of dynamic access key；Here by the preset time period initial time and the end time that arrange dynamic access key, can so that the dynamic access key ultimately generated be subject to presetting the restriction of effective time period, once exceed the effective time section preset, even if then dynamically access key is correct, gate inhibition's subsystem also disapproves the operator of the Intelligent handhold management terminal sending dynamic access key and passes through gate inhibition, again ensure that the safety in factory with this, stop non-security personnel by gate inhibition's subsystem；

C in the current Password Input frame of () gate inhibition subsystem each gate inhibition of extraction, corresponding often group is passed through and is allowed color, and calculating obtains the corresponding average gray often organizing current permission color in the current Password Input frame of each gate inhibition；Wherein, average gray I (n) of one group of permission color that passes through that the current Password Input frame of each gate inhibition is corresponding is obtained by equation below:
