Specifically, the type of the mobile terminal device is not limited, and may be, for example, a mobile phone, a tablet, a notebook, or the like. The mobile terminal device firstly performs identity authentication on the received user information to judge whether a current operator of the device is a legal user, for example, whether the current operator is a device owner. If the user information passes the identity authentication, it is considered that the current user may be allowed to operate the mobile terminal device. The method of performing identity authentication is not unique, for example, a user may input a password in the mobile terminal device, and when the received password input by the user matches a pre-stored password, the mobile terminal device determines that the identity authentication is passed and the current user is legal when operating. After the user information received by the mobile terminal equipment passes the identity authentication, the received user instruction can be sent to the lock cylinder so as to control the locking state of the lock cylinder.

In an expandable manner, when receiving a signal from the mobile terminal device, the wireless device of the lock cylinder first determines whether the mobile terminal device is a trusted device of the lock cylinder, if so, the wireless device normally receives the signal from the mobile terminal device, and if not, the wireless device does not receive the signal sent by the mobile terminal device, considering that the current mobile terminal device is not authorized, and cannot be allowed to control the lock cylinder. The mode of verifying whether the mobile terminal device is a trusted device of the lock cylinder is not unique, for example, a user can scan a two-dimensional code on the lock cylinder through the mobile terminal device, and the like, bind an account of unlocking software in the mobile terminal device with the current lock cylinder, subsequently directly adopt the account bound with the lock cylinder to log in the unlocking software, and send an instruction to the lock cylinder through the unlocking software.

The configuration and type of the resilient drive member is not unique and thus operates in a different manner. Taking the example that the elastic driving member includes the motor 9, when receiving the electrical signal, the operation mode of the motor 9 is rotation, and the rotation of the motor 9 can drive the locking pin 13 to displace. The elastic driving part also comprises an elastic device which is driven to stretch or compress when the motor 9 rotates, so as to drive the locking pin 13 to displace, eject or insert into the lock cylinder body, and change the operation state of the lock cylinder body.

The locking pin 13 is driven by the elastic driving piece to pop out of the lock cylinder body or insert into the lock cylinder body. Specifically, the lock cylinder body is provided with a cavity communicated with the outside, and the direction of the communication between the cavity and the outside is the ejecting or inserting direction of the locking pin 13, so that the locking pin 13 can move conveniently. The shape and type of the locking pin 13 are not exclusive, and in this embodiment, the locking pin 13 may be a metal pin, which is strong and durable, and has a good shape locking effect similar to a nail and occupies a small volume. Generally, after the lock cylinder body is installed on a door, the side closest to the ground is the lower side, and the side farthest from the ground is the upper side, for example, the opening of the cavity formed in the lock cylinder body is vertically upward. Therefore, the locking pin 13 arranged in the cavity can be popped out of the lock cylinder body under the action of the elastic driving piece and inserted into the cavity under the combined action of the elastic driving piece and gravity, the probability of obstruction in the movement process is low, and the working performance of the locking pin 13 can be improved. In addition, the cavity formed in the lock cylinder body generally penetrates through at least two devices in the lock cylinder body, so that when the locking pin 13 is inserted into the cavity, the locking pin 13 can fix the at least two devices, and prevent two or more devices from relative displacement, such as rotation, and the like, so that the lock cylinder body is in a locked state.

The locking pin 13 is spacing to the lock core body, and when the lock core body was in the locking state, the mutual locking between some or all devices of lock core body could not carry out the operation of unblanking, and when the lock core body was in the unblock state, each device of lock core body can move as required, and the user accessible follow-up operation realizes unblanking, for example rotates the knob and realizes unblanking etc.. Facilitating subsequent unlocking operation.

Specifically, when the first electric signal is an electric signal for controlling the lock cylinder body to be in the unlocking state, that is, after the first electric signal is applied to the elastic driving member, the elastic driving member drives the locking pin 13 to pop out of the cavity, the control device 6 starts timing at the time of sending the first electric signal, and when the preset time is reached, the second electric signal is sent to the elastic driving member, and the elastic driving member runs in the opposite direction after receiving the second electric signal. For example, when the motor 9 starts to rotate clockwise after receiving the first electrical signal to eject the locking pin 13 out of the cavity, the control device 6 sends the second electrical signal to the elastic driving member after the time interval for sending the first electrical signal reaches the preset time period, that is, when the motor 9 rotates clockwise to reach the preset time period, and the motor 9 starts to rotate counterclockwise after receiving the second electrical signal to displace the locking pin 13 in the direction opposite to the previous direction of movement, that is, to insert the locking pin into the cavity. Taking the first electrical signal as an electrical signal for indicating unlocking as an example, when the motor 9 receives the first electrical signal, it starts to rotate clockwise, and compresses one end of the elastic device, so that the locking pin 13 connected with the other end of the elastic device is ejected out of the cavity of the locking body, and the lock cylinder body is in an unlocking state. After the motor 9 clockwise rotation reached to predetermine long the time, motor 9 began anticlockwise rotation, and tensile elastic device's one end makes elastic device's the other end pulling stop pin 13 get back to in the cavity, realizes the automatic shutting of lock core body, has improved intelligent access control system's security. The specific value of the preset time duration is not unique, and may be set according to actual requirements, and is generally the total time duration that the user can complete the door opening, door entering and exiting, and door closing processes, for example, may be 10s, or other time durations that may be considered by those skilled in the art to be realizable, as long as those skilled in the art consider realizable.
