[0002] Access control refers to the prohibition authority of a door, which is a precaution against the door. It uses certain means to determine whether the user has the authority and thus determines whether the user is qualified to pass, and then performs corresponding control to allow or prohibit the user from passing. However, the existing access control is prone to failure to close in time due to various reasons. At this time, it is usually directly judged as a fault and then the corresponding staff is reminded to deal with it in time by issuing an audible and visual alarm. However, the reason why the access control cannot be closed in time may also be that it remains open for a long time (such as ten minutes) due to some need.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-Figure 6As shown, a fault identification system based on a computer network includes a door frame 1, a door leaf 2, an electronic lock 3, a monitoring camera 4, a data processing module 5, a network module 6, a computer 7, and a communication module 8. The door frame 1 is horizontally hinged with the door leaf 2. The electronic lock 3 includes a lock body 9 and a buckle box 10. The lock body 9 and the buckle box 10 are respectively fixed at the opening and closing positions of the door frame 1 and the door leaf 2. An electric push rod 11 and a controller 12 are fixed in the lock body 9. The push rod of the electric push rod 11 can be plugged with the buckle box 10 to achieve the locking of the lock body 9 and the buckle box 10. The lock body 9 and the buckle box 10 are jointly installed with a proximity switch 13. The electric push rod 11, the proximity switch 13 and the controller 12 are electrically connected. The controller 12 is externally connected to a power supply. The controller 12 is a known The prior art, such as a single-chip microcomputer and a PLC, the output end of the controller 12 is connected to the input end of a monitoring camera 4, the monitoring camera 4 is used to shoot the space environment where the door frame 1 and the door leaf 2 are located, the output end of the monitoring camera 4 is connected to the input end of a data processing module 5, the data processing module is a known prior art, such as a single-chip microcomputer, the output end of the data processing module 5 is connected to the input end of a network module 6, the network module is a prior art, and a wired or wireless type can be used as needed, such as a WiFi module, the output end of the network module 6 is electrically connected to the input end of a computer 7, the computer 7 is an external power supply, the output end of the computer 7 is electrically connected to the input end of a communication module 8, and the communication module 8 communicates with external communication equipment.

[0022] When in use, the controller 12 controls the electric push rod 11 to retract the push rod, so that the lock body 9 and the buckle box 10 are unlocked. At this time, the door leaf 2 can swing back and forth to allow people to pass. When passing, the proximity switch 13 changes from a conducting state to a non-conducting state, and starts timing (called a1 state). After passing, the person actively closes the door leaf 2 within a specified time. At this time, the proximity switch 13 resumes conduction, the timing stops and resets, indicating that there is no fault in closing the door leaf 2. Then the controller 12 controls the electric push rod 11 to extend the push rod, the lock body 9 and the buckle box 10 are re-locked, and passage is prohibited (called a2 state). When in the a1 state, if the timing duration exceeds the set value, the controller 12 controls the surveillance camera 4 to work, and the surveillance camera 4 shoots the door frame 1 and the door leaf. 2 surrounding conditions, and upload the image data to the data processing module 5 for comparison and analysis with the database. If it is determined that there is a person or object staying between the door frame 1 and the door leaf 2, it is considered that this state is maintained for a long time by human initiative, that is, no personnel processing is required; if it is determined that there is no person or object staying between the door frame 1 and the door leaf 2, it is considered that there is a fault or negligence that causes the door leaf 2 to not close, that is, personnel processing is required. At this time, the network module 6 will output the signal and the monitoring of the monitoring camera 4 to the computer 7, and display it on the display screen of the computer 7. Then the staff sitting in front of the computer 7 will remotely determine whether the staff needs to process. If necessary, the communication module 8 will call the corresponding communication equipment to remind the staff to process.

[0023] The electronic lock 3 also includes a mechanical password mechanism, which includes a support frame 15. The lock body 9 is fixed with a support frame 15 that runs through the front and back. A horizontal servo motor 16 with a brake function is fixed to the right end of the support frame 15. The rotating shaft of the servo motor 16 is rotatably connected to the upper part of the support frame 15 along the left and right horizontal directions. The middle and lower parts of the support frame 15 are rotatably connected from top to bottom with a plurality of support shafts 17 that are horizontally arranged along the left and right directions. The two adjacent support shafts 17 and the rotating shaft of the servo motor 16 are synchronously connected through a transmission mechanism. The transmission mechanism is a known prior art, such as a synchronous belt. Each of the support shafts 17 and the rotating shaft of the servo motor 16 is respectively equipped with a password disk 18. The password disk 18 includes a regular quadrangular prism 19, a tension spring 20, a regular polygonal prism 21, and a regular quadrangular hole 22. The regular quadrangular prism 19 and the regular polygonal prism 21 are horizontally arranged in the left and right directions. The column 21 is coaxially penetrated by a regular quadrangular hole 22 on the left and right sides, and the number of sides of each regular polygonal prism 21 is an even number (the side of the prism mentioned in the text refers to the side of the prism in mathematics, which will not be repeated), the regular quadrangular prism 19 is gap-inserted in the regular quadrangular hole 22, and its four side faces correspond to the four inner side faces of the regular quadrangular hole 22, and the left and right parts of each side face of the regular quadrangular prism 19 are respectively fixed with tension springs 20 on the inner side faces of the corresponding regular quadrangular hole 22, and the regular quadrangular hole 22 is gap-inserted with the regular quadrangular prism 19 under the pulling force of each tension spring 20, and each outer side face of the same regular polygonal prism 21 is respectively provided with completely different or completely identical marks 23, and the front part of the lock body 9 is penetrated by a pressing hole 24 of the same number as the regular polygonal prism 21, and each pressing hole 24 corresponds to the password disk 18 front and back, and an image recognition device is also installed in the lock body 9, and the image recognition device is located behind the mechanical password mechanism for identifying the mark 23.

[0024] Furthermore, in order to improve the security and convenience of locking, a mechanical password mechanism is provided, and the servo motor 16 is controlled by the controller 12 to rotate, so that different sides of each regular polygonal prism 21 can be presented to the personnel through the pressing port 24. Then, the personnel can press the corresponding regular polygonal prism 21 backward in sequence as needed to move the regular polygonal prism 21 backward and be recognized by the image recognition device. Since the outer sides of the same regular polygonal prism 21 are respectively provided with completely different or completely identical identifications 23, the image recognized by the image recognition device will uniquely correspond to another image (i.e., the password) according to the identification data entered in advance, and the process of entering the password is realized. When the input is correct, the controller 12 will control the electric push rod 11 to retract, so that the lock body 9 is separated from the buckle box 10, and unlocking is achieved. If the input is incorrect, it needs to be re-entered.

[0025] There are three support shafts 17, and each support shaft 17 and the rotating shaft of the servo motor 16 are respectively installed with three code disks 18. The number of edges of the regular polygonal prism 21 is ten, and the ten outer side surfaces of the ten regular polygonal prisms 21 are respectively provided with the numbers "0, 1, 2, 3, 4, 5, 6, 7, 8, 9" in the same order, and the numbers on the front side surfaces of the ten regular polygonal prisms 21 are not the same at the same time. The side surfaces of the other two regular polygonal prisms 21 are respectively provided with the Chinese characters "Delete" and "Confirm".

[0026] Furthermore, the password is composed of multiple digits. When the servo motor 16 rotates normally, the angle of each rotation is any integer multiple of thirty-six degrees, and each time the rotation stops, the front end surface of the regular polygonal prism 21 will be displayed forward through the pressing port 24. No matter how the servo motor 16 rotates normally, the ten digits "0, 1, 2, 3, 4, 5, 6, 7, 8, 9" and the two words "delete" and "confirm" will always be displayed through the front side of the regular polygonal prism 21. The difference is that "0, 1, 2, 3, 4, 5, 6, 7, 8, 9" are not the same, which makes the position of the user's hand different from the hand position at other times when entering the password each time, thereby reducing the risk of password leakage to a certain extent, that is, reducing the risk of inferring the password by recording hand movements or identifying fingerprint positions, and using "delete" and "confirm" to delete and confirm the input password, that is, the two regular polygonal prisms 21 can be recognized by the corresponding image recognition device and then fed back to the controller 12 to execute deletion and confirmation of the input password.

[0027] The image recognition device includes the same number of recognition components 26 as the regular polygonal prism 21, and the recognition component 26 includes two self-reset button switches 27 and an recognition camera 28. The self-reset button switches 27 are arranged on the left and right sides of the recognition camera 28. The self-reset button switch 27 and the recognition camera 28 are respectively fixed in the lock body 9 along the front and back directions, and are respectively electrically connected to the controller 12. Each of the recognition components 26 corresponds to each regular polygonal prism 21 front and back, and when the regular polygonal prism 21 is pressed backward, the self-reset button switch 27 in the corresponding recognition component 26 can be pressed.

[0028] Furthermore, when the regular polygonal prism 21 is pressed backward, the regular polygonal prism 21 presses the self-reset button switch 27 (either one or both at the same time) in the corresponding identification component 26, which causes the identification camera 28 in the identification component 26 to capture an image of the rear side surface of the regular polygonal prism 21, and then transmits the image data to the controller 12, which then performs image matching to determine whether the input password is correct. If correct, the electric push rod 11 is controlled to retract the push rod, thereby unlocking the lock body 9 and the buckle box 10.

[0029] A vertical baffle 29 is also fixed in the support frame 15, and a plurality of through openings 30 are penetrated by the baffle 29 in the front-to-back direction, and each of the through openings 30 corresponds to each regular polygonal prism 21 in the front-to-back direction, and the two self-reset button switches 27 in each of the identification components 26 are respectively inserted into the through openings 30 with gaps, and the width W of the through openings 30 is greater than the width of the side of the regular polygonal prism 21 and less than twice the width of the side of the regular polygonal prism 21, and the length L of the through opening 30 is not less than the length of the side of the regular polygonal prism 21.

[0030] The baffle 29 can partially shield the regular polygonal prism 21 to reduce interference of the logo 23 in other parts to the recognition camera 28, and the rear side of the regular polygonal prism 21 can be displayed to the recognition camera 28 through the opening 30 for recognition.

[0031] The lock body 9 is also fixed with a speaker 31 , and the speaker 31 is electrically connected to the controller 12 . The lock body 9 is penetrated by a plurality of speaker holes 32 , and the speakers 31 correspond to the speaker holes 32 .

[0032] When the electric push rod 11 is extended, the controller 12 controls the speaker 31 to emit a corresponding sound to remind the personnel that it is locked; when the electric push rod 11 is retracted, the controller 12 controls the speaker 31 to emit a corresponding sound to remind the personnel that it is unlocked.

[0033] A left plug-in ear 33 and a left connecting plate 34 are fixed to the rear end of the buckle box 10 along the front-to-back direction, and a right plug-in ear 35 and a right connecting plate 36 are fixed to the rear end of the lock body 9 along the front-to-back direction. The left plug-in ear 33 is inserted into the door frame 1, and the door frame 1 is threadedly connected with a left fastening bolt 37. The left fastening bolt 37 is plugged into the left plug-in ear 33 and the left connecting plate 34 to fasten the buckle box 10. The right plug-in ear 35 is inserted into the door leaf 2, and the door leaf 2 is threadedly connected with a right fastening bolt 38. The right fastening bolt 38 is plugged into the right plug-in ear 35 and the right connecting plate 36 to fasten the lock body 9. The door leaf 2 and the door frame 1 are jointly equipped with a door closer 41, and the door leaf 2 and the door frame 1 are automatically closed under the action of the door closer 41.

[0034] The proximity switch 13 includes a reed switch 39 and a permanent magnet 40, wherein the reed switch 39 is fixed in the middle of the buckle box 10, and the permanent magnet 40 is fixed in the left part of the lock body 9. When the lock body 9 is close to the buckle box 10 by a certain distance, the permanent magnet 40 is close to the reed switch 39 by a certain distance, so that the reed switch 39 is turned on and at this time, if the push rod of the electric push rod 11 is extended, it can be plugged into the buckle box 10 to realize the locking of the lock body 9 and the buckle box 10.

[0035] When the door leaf 2 and the door frame 1 are closed, the distance between the lock body 9 and the buckle box 10 is shortened to a set distance. At this time, the permanent magnet 40 affects the reed switch 39, thereby making the reed switch 39 conductive, and then transmitting a signal to the controller 12, so that the controller 12 controls the electric push rod 11 to extend after receiving the signal.

[0036] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
