Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1
As shown in fig. 1, 2, 3, 4, 5 and 6, a relatively simple lock system and method of use is provided in one embodiment. From the physical construction of the hardware of the embodiment, the invention comprises two parts, key 1 and lock cylinder 2, it being noted in particular that the shapes of the lock cylinder and key shown in the figures can be varied according to the design requirements. The lock core 2 and the key 1 are connected through the interface module, when the key is used, the first interface module 13 on the key 1 is aligned with the second interface module 23 of the lock core 2, communication data is transmitted to the lock core through the interface module, and after the lock core passes verification, a driving device in the lock core is driven to unlock.
The key 1 comprises a power module 11 and a first controller 12, wherein the power module 11 supplies power to all functional modules in the key 1 and simultaneously supplies power to the lock cylinder through a power line. The power supply is not arranged in the lock cylinder, and when each functional module in the lock cylinder needs to supply power, the external power supply must be obtained through the second interface module 23. The outermost part of the key 1 is a first housing 10, and both the power module 11 and the first controller 12 are disposed in the first housing 10. The edge of the first housing 10 is provided with a through hole, a first interface module 13 is arranged in the through hole, the first interface module 13 comprises a second housing 130, and four contact points, namely a first contact point 131, a second contact point 132, a third contact point 133 and a fourth contact point 134, are arranged in the second housing 130; wherein the first contact point 131 and the fourth contact point 134 are connected to the power module 11 through a power line; the second contact point 132 and the third contact point 133 are connected to the first controller through data lines.
The lock cylinder 2 comprises a second controller 21 and a driving device 22, the outermost part of the lock cylinder is a third shell 20, the edge of the third shell 20 is provided with a through hole, a second interface module 23 is arranged in the through hole, the second interface module 23 comprises a fourth shell 230, and the fourth shell 230 is provided with four contact points, namely a fifth contact point 231, a sixth contact point 232, a seventh contact point 233 and an eighth contact point 234. The fifth contact point 231 and the eighth contact point 234 are connected with each module needing power supply in the lock cylinder through a power line, and comprise a second controller 21 and a driving device 22; the sixth contact point 232 and the seventh contact point 233 are connected to the second controller through a data line.
One of the points of the present embodiment is that, when the key 1 is in contact with the lock cylinder 2, the power supply module 11 can supply power to the lock cylinder 2 through the power line after the first interface module 13 is in contact with the second interface module 23 without considering the polarity of the power supply. The above-mentioned nonpolar design schemes have two schemes, one scheme is that the first contact point 131 and the fourth contact point 134 are connected with the positive electrode of the power module 11 through a power line, and the second housing 130 is connected with the negative electrode of the power module 11 through a power line; correspondingly, the fifth contact point 231 and the eighth contact point 234 are connected with the positive electrode of each module requiring power supply in the lock cylinder through a power line, and the fourth housing 230 is connected with the negative electrode of each module requiring power supply in the lock cylinder through a power line. The scheme is characterized in that two contacts at the outermost sides in the key 1 and the lock cylinder 2 are fixedly connected with the anode of the power module, and the shell of the interface module is used as a ground wire.
Alternatively, the first contact point 131 and the fourth contact point 134 are connected to the positive electrode or the negative electrode of the power module 11 through power lines, respectively; the fifth contact 231 and the eighth contact 234 are connected to the input end of the rectifying circuit 24 through power lines, and the output end of the rectifying circuit 24 is connected to the positive electrode and the negative electrode of each module requiring power supply inside the lock cylinder through power lines. The characteristic of the scheme is that a rectifying circuit 24 is added between the power receiving contact of the lock cylinder and the power utilization functional module. The positive and negative polarities of the output end of the rectifying circuit are fixed no matter the positive and negative polarities of the input end of the rectifying circuit.
On the basis of the above-mentioned power supply non-polarity design, it is also necessary to consider the matching of the data communication interface, and the contacts for transmitting data in the first embodiment include the second contact 132 and the third contact 133 in the key 1, and the sixth contact 232 and the seventh contact 233 in the lock cylinder 2. The solution is to adapt the second contact point 132 and the third contact point 133 or to adapt the sixth contact point 232 and the seventh contact point 233. For example, the second contact 132 transmits a clock signal and the third contact 133 transmits a data signal; the sixth contact 232 and the seventh contact 233 may transmit both clock signals and data signals.
It should be noted that the contacts of the key 1 or the lock cylinder 2 for connecting the data lines may be designed as one, three or more, and the embodiment only uses two data line contacts as an illustration of the principle of the present invention. The number of contacts to transmit data can be selected by those skilled in the art as desired and the data transmission contacts can be adaptively processed in accordance with the spirit of the present invention.
Another point of the present embodiment is that, after the key 1 and the lock cylinder 2 are contacted, in order to achieve stable fixing of the two, a magnet is disposed on the second housing 130 or the fourth housing 230, and the second housing 130 or the fourth housing 230 is made of a magnetic material containing iron, nickel, etc., so that the fixing of the first interface module 13 and the second interface module 23 is facilitated.
Another point of creation of this embodiment is that the first contact point 131, the second contact point 132, the third contact point 133, and the fourth contact point 134 can be displaced to some extent; the fifth contact point 231, the sixth contact point 232, the seventh contact point 233, and the eighth contact point 234 maintain a fixed position unchanged. The advantage of this design is that a stable connection between the contact points can be ensured. When the key and the lock cylinder are not in contact, the first contact point 131, the second contact point 132, the third contact point 133 and the fourth contact point 134 are extended to the outside to the farthest distance due to the elastic member, and after the contact points are in contact, the first contact point 131, the second contact point 132, the third contact point 133 and the fourth contact point 134 are driven to move toward the inside of the key due to the force generated by the magnet or due to the force generated by the human body until the first interface module 13 and the second interface module 23 are completely attached.
After the lock cylinder 2 is electrified, firstly judging whether the power supplied by the legal key 1 to the lock cylinder 2 is the power supplied by the legal key 1, and sending a request command to the first controller 12 by the second controller 21 through the data line, wherein the first controller 12 should send a response command after receiving the request command; after receiving the response command, the second controller 21 determines that the power supplied by the key 1 is legal, and can proceed to the next step. The legal key refers to a key capable of responding to a request command of the second controller, the request response process can be realized in various modes, and is one of conditions for guaranteeing the safety of the lockset system, if the request response step fails, the lock cylinder resends the request command at certain intervals on the premise of being electrified until receiving the response command or powering off. If the request command issued by the second controller 21 is not responded to within a predetermined time, the second controller 21 does not issue the request command any more even when the key cylinder is in the energized state.
After receiving the response command, the second controller 21 sends the unique identification code of each lock core to the first controller 12 through the data line, and after receiving the lock core identification code, the first controller 12 judges whether the lock core is in the unlocking range of the first controller, if not, the second controller performs invalid unlocking processing, and can trigger the warning device. If the password is within the unlocking range of the first controller 21, the first controller 12 further judges whether a pre-sent password exists in the key, if the pre-sent password exists, the first controller sends the pre-sent password to the second controller 21 through a data line, the second controller verifies the validity of the password after receiving the password, and if the password is valid, the power supply line of the driving device 22 is conducted, so that unlocking is achieved.
The lock system and the unlocking method corresponding to the embodiment are relatively simple systems and methods, and are characterized in that the lock can be unlocked after the key 1 and the lock cylinder 2 are correctly contacted, and the lock has the advantages of convenient use and obvious defects in safety.
Example two

In order to solve the above-mentioned problems, the present embodiment provides a high-security communication method and a lock system used by the same.
As shown in fig. 7, the lock system of the present embodiment further includes a mobile terminal 3 and a background server 4 on the basis that the lock system includes a key 1 and a key cylinder 2.

The third wireless communication module 33 in the mobile terminal 3 communicates with the background server 4 and enables transmission of data. The communication mode between the third wireless communication module 33 and the background server 4 is preferably a cellular data mobile communication network, wiFi, GPRS, NFC.
The background server is responsible for registering keys, lock cylinders, mobile terminals, APP and users; the mobile terminal is typically a mobile device held by a worker and may be a cell phone, tablet computer, PDA, PC. The APP is a program running in the mobile terminal and can be understood as an interface of human-computer interaction; it is the mobile terminal that is the hardware with the operating system, since it needs to run the APP. The user is a virtual main body with certain operation authority given by the background server, and the virtual main body often corresponds to a specific staff member.
The background server is responsible for managing an unlocking plan and unlocking according to the plan; specifically, when the key, the lock core, the mobile terminal, the APP and the user are consistent with the authorization of the background server, unlocking can be realized.
After the background server is authorized, a user is logged in through APP operation in the mobile terminal, a key and a lock cylinder are initialized, and a worker unlocks according to the authorization of the background server.
Example III
