Another more specifically embodiment is described below.
Elevator integrated controller functional parameter is generally used for arranging the functional parameter under the various operating modes of elevator, and for example, elevator functions parameter can be divided into D group: status surveillance parameter group; F group: parameter arranges group; Y group: producer's parameter group.
Taking D group as example, D group can be divided into again D00 group, D01 group below, D02 group etc., and wherein every group of functional parameter by different meanings forms, and taking D00 group as example, D00 group is made up of D00.00, D00.01, D00.02 etc. below, and each parameter represents an implication.
First a special parameters group is set in elevator integrated controller functional parameter group: H parameter group.H parameter group is made up of multiple parameter group again.Taking 3 parameter group as example, in table 1, formed by each group of cipher code set H00, bundle of permissions and storage space H06 respectively.And under bundle of permissions, divide multiple grade bundle of permissions, taking 5 grade bundle of permissions as example, be respectively grade 1 bundle of permissions to class 5 bundle of permissions (H01～H05).
Table 1
Cipher code set H00 is made up of multiple cipher, taking 6 passwords as example, in table 2, form by entering password H00.00 and class user password (grade 1 user cipher H00.01, grade 2 user cipher H00.02, grade 3 user cipher H00.03, class 4 user cipher H00.04, class 5 user cipher H00.05) respectively.Only have the correct authority that enters password and just can obtain modify feature parameter below of input, certainly will obtain this authority also needs further password, i.e. each class user password.The corresponding different grade bundle of permissions separately of each class user password, corresponding grade 1 bundle of permissions of grade 1 user cipher H00.01, corresponding grade 2 bundle of permissions of grade 2 user cipher H00.02, corresponding grade 3 bundle of permissions of grade 3 user cipher H00.03, the corresponding class 4 bundle of permissions of class 4 user cipher H00.04, the corresponding class 5 bundle of permissions of class 5 user cipher H00.05.
Table 2
Each grade bundle of permissions is made up of multiple data elements, and taking 60 data elements as example, each data element is 16 bits (can be that two scale notation can be also the decimal scale, be two scale notation in the present embodiment).For example grade 1 bundle of permissions H01, is made up of 60 data element H01.00～H01.60 respectively.Taking H01.00 as example, if each numerical digit represents a kind of elevator parameter, grade 1 bundle of permissions H01 has comprised 16*60=960 elevator parameter, and this is more than sufficient for most elevators, and multiple data elements of bundle of permissions comprise elevator all functions parameter.In other embodiments, also can represent a kind of elevator parameter by two above numerical digits.The numerical digit of data element be 1 and 0 respectively representative allow and do not allow to revise elevator parameter, in table 3, represent that the numerical digit 2 of this data element, the elevator parameter of numerical digit 8 sum digit 16 representatives allow amendment, and the elevator parameter of other numerical digit representatives of this data element does not allow amendment.In other embodiments, can be also 1 and 0 respectively representative do not allow and allow to revise elevator parameter.And while adopting two above numerical digits to represent a kind of elevator parameter, for example, while being 2 figure place position, 00 and 11 respectively representative do not allow and allow to revise elevator parameter.
| Numerical digit | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 |
| Authority | 0 | 1 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 1 |
Table 3
Storage space is also by multiple data elements, and taking 2 data elements as example, each data element is 16 bits, is respectively H06.00 and H06.01.H06.00 represents storage location, and H06.01 represents unloading operation.For example H06.00 parameter being made as to figure place 1～figure place 10 is 1, represents to represent to store respectively the parameter of above-mentioned setting (the parameter setting of cipher code set and bundle of permissions) into guidance panel internal storage space 1-10.When elevator producer carries out factory testing to the all-in-one dispatching from the factory, can select to be made as figure place 1～figure place 10 by H06.01 parameter be 1, represents to store the parameter modification authority that is stored in the inner particular space 1-10 of guidance panel into elevator integrated machine inside.
H parameter group only just has demonstration in the time that VIP guidance panel is connected with elevator integrated controller, and when normal operations panel is connected with elevator integrated controller, H parameter group is hidden automatically, cannot carry out parameter setting to it.VIP guidance panel is that elevator integrated controller producer is the professional guidance panel that the expert of Elevator Factory is equipped with.
