Fig. 6 is a flow chart complementary to the flow chart shown in fig. 5, and fig. 6 illustrates the details of the present disclosure by taking an example in which one cell includes two bidirectional personnel control gates, twenty apartment buildings, and fifty families in each apartment building.
As shown in fig. 6, in S602, the target number and attributes of the key fob are determined. A first set of entrance control menus can be set up in the programmer, comprising two bi-directional gates and a master controller of the first building, programming a certain number of remote keys in order to respond to low frequency commands issued by the relevant master controller, if 100 remote keys are required for each fifty family, the number of programmed remote keys can be slightly greater than 100, for example 120, to use the backup margin.
In S604, a plurality of matching information sets are generated based on the attributes and the target number.
In S606, a matching information database is created based on the plurality of matching information groups. After programming, storing the identity data of the remote control key in a first group; the latter data sets are built in the same manner, for a total of twenty key fob databases.
In S608, the matching information between the key fob and the master is stored in the matching information database according to the attribute of the key fob. After the database of all the remote control keys is established, the programmer and the cell gate control system are connected, and all the remote control key databases are transmitted to the two bidirectional gates, so that all the remote control keys and the boxing gates at the cell gate can establish low-frequency and high-frequency communication responses.
The data of the remote control keys from the first group to the twentieth group can be respectively transmitted to each access master controller, so that each master controller can respectively establish low-frequency and high-frequency communication response with the remote control keys of related groups, and communication cannot be established between the remote control keys and the master controllers of different buildings.
After the data communication is established, the remote control keys can be respectively registered and issued to the residents. When the remote control key is damaged, the remote control keys with the backup number can be registered and directly issued; the bad remote control key can be repaired or directly destroyed; when the remote control key is lost, the data of the remote control key with the corresponding number in the programmer is deleted, and then the data refreshing is respectively carried out on the entrance gate and the entrance guard system of the corresponding building.
