Head P2 external transmission.
Solution lock core chip U3 another function is to provide key-press module 6, and button is connected on solution lock core chip U3 data input pin
Module 6, key-press module is terminated in solution lock core chip U3 PC0.Different electric control locks 2 is opened really by key-press module 6
Fixed, key-press module 6 can also be designed to numeric keypad in the way of prior art, be controlled by way of setting password automatically controlled
The unlatching of lock 2.
The power management of security controller 3 and unlocking device 4 can be respectively provided with power supply supply, in order to further increase security control
The security of device 3 processed, can set security controller 3 when not in use（Electric control lock 2 is closed）When power off, that is, belong to not power transmission side
Formula.If want to open electric control lock 2, upper electricity is carried out by unlocking device 4.Based on this mentality of designing, control chip
U1 vdd terminal and control communication module U2 vdd terminal are attempted by positive voltage input, and aviation socket P1 3 holes are positive voltage
Input, i.e. control chip U1 vdd terminal and control communication module U2 vdd terminal are attempted by aviation socket P1 3 holes, are waited
Aviation plug P2 power supply.Unlocking device 4 installs supplying cell 7 additional, and supplying cell 7 is connected on aviation by Power convert control module 8
On plug P2 3 holes.The voltage of supplying cell 7 is usually+5V, after Power convert control module 8 is reduced to+3.3V, is connected on
Aviation plug P2 3 holes.When aviation plug P2 is inserted on aviation socket P1 ,+the 3.3V in aviation plug P2 3 holes passes through aviation
Socket P1 3 holes reach control chip U1 vdd terminal and control communication module U2 vdd terminal, so that the work of security controller 3
Make, providing power supply for unblock electric control lock 3 supports basis.
In actual use, when staff needs the electric control lock 2 on opening signal machine body 1, staff carries
The aviation plug P2 of unlocking device 4 is inserted on aviation socket P1, and input needs to beat on key-press module 6 by unlocking device 4 to scene
Open the numbering or password of electric control lock 2.Solution lock core chip U3 is received and is reached aviation plug by unlocking communication module U4 after data message
P2.Aviation plug P2 reaches the control communication module U2 in semaphore body 1, control communication module U2 by aviation socket P1 again
Control chip U1 is reached again.Control chip U1 sends to corresponding electric control lock control module and controlled according to the data code of input
Signal（High level or low level）So as to trigger the opening of electric control lock 2.
In order to increase property easy to use, security protection measure is improved also for further, semaphore main control module 9 can also be included
With semaphore background monitoring center 10.Semaphore main control module 9 is the control unit being present in the prior art in semaphore body 1
Part, semaphore background monitoring center 10 then obtain data message from semaphore main control module 9.As shown in Figure 10 and Figure 11, signal
Machine main control module 9 includes semaphore communication module U6 and semaphore master chip U5, and semaphore communication module U6 is attempted by aviation and inserted
On seat P1, semaphore communication module U6 CAN_H ends are attempted by aviation socket P1 7 holes, semaphore communication module U6's
CAN_L ends are attempted by aviation socket P1 8 holes, i.e., from the aviation socket P1 data messages obtained while are transmitted to control communication mould
Block U2 and semaphore communication module U6.Semaphore communication module U6 connects with semaphore master chip U5, semaphore communication module U6
CAN_TX ends be connected with semaphore master chip U5 CAN_TX ends, semaphore communication module U6 CAN_RX ends and signal owner
Chip U5 CAN_RX ends are connected.The data message that semaphore communication module U6 obtains from aviation socket P1 is transmitted to signal owner
Chip U5.Data storage U7 is connected to by prior art manner on semaphore master chip U5, can be by semaphore master chip U5 institutes
The data message operation received preserves, and adds security and readability.Semaphore master chip U5 equally presses prior art manner
It is connected by ethernet controller U8 with semaphore background monitoring center 10, so as to input user by background monitoring center
Name and cipher control electric control lock, realize the local to electric control lock and long-range double control.
In actual use, when user is in the password that key-press module 6 inputs, it can be by semaphore body 1
Control chip U1 is verified, can also be verified by semaphore background monitoring center 10, realize double-deck Validation Mode, from
And more complicated cryptographic algorithm can be applied.According to being actually needed, signal can also be sent from semaphore background monitoring center 10
Control communication module U2 in semaphore body 1, directly open electric control lock 2.To realize convenient control to electric control lock 2, one
As electric control lock can individually be controlled using local or backstage method；Security for guarantee to electric control lock 2, local every
Unlocking device 4 has unique number, and only numbering is correct, continues to input that password is just effective, and must also there be solution at background monitoring center 10
The user for locking authority operates remote control, can just manage electric control lock 2；Every time during unblock, semaphore master chip U5 will can be received
Device numbering or user name be stored in data storage U7, and preserve semaphore master chip U7 calculating system time, with
It is convenient subsequently to check the personnel safeguarded to semaphore and temporal information.Certainly, it is more for the safer prevention and control mode of electric control lock 2
Level prevention and control（It is local and remote to control together）, for security controller 3 first by electric on unlocking device 4, guarantee scene is staff
Operation；And then by controlling communication module U2 and the double code of semaphore background monitoring center 10 to verify, so as to realize signal
The multistage anti-theft control of machine body 1.
