[0002] Highway manholes are underground or above-ground structures within highway infrastructure used to house and install various pipelines, cables, and drainage systems. Their core function is to ensure the safe operation and convenient maintenance of highway communication, power, and drainage systems. Communication manholes are primarily responsible for communication and power transmission, housing fiber optic cables and other communication lines to ensure smooth operation of traffic monitoring, toll collection systems, and emergency communications.
[0003] For security management, electronic locks are now being used to replace ordinary mechanical locks. The advantages of electronic locks are that they record information and are secure and controllable. At the same time, they can use actuators such as motors to automatically open and close the lock. In this case, there is no need to set an operating handle on the surface of the lock body, thus avoiding the possibility of being forcibly destroyed.

[0032] The technical solutions in this application will be further described in detail below with reference to the accompanying drawings.
[0033] This application discloses an intelligent door lock system for highway pipeline wells. Please refer to [link / reference]. Figure 1 and Figure 2 In some examples, the smart door lock system for highway manholes disclosed in this application includes a lock body 1, an electronic authentication module 2, a drive assembly 3, a locking rod 4, a controller 5, a cover plate 6, and a mechanical locking lock 7. The electronic authentication module 2 is installed on the second surface of the lock body 1, and the electronic authentication module 2 works by transmitting and receiving data and authenticating identity through wireless communication.
[0034] The drive assembly 3 is located in the cavity on the lock body 1. Figure 3 Inside (as shown), the locking rod 4 is slidably connected to the lock body 1 and connected to the drive assembly 3. The function of the drive assembly 3 is to drive the locking rod 4 to move. When the locking rod 4 is inserted into the locking hole on the inner wall of the pipe well, the locking action is completed; when the locking rod 4 leaves the locking hole on the inner wall of the pipe well, the opening action is completed.
[0035] The controller 5 is located on the second surface of the lock body 1 and is electrically connected to the electronic authentication module 2 and the drive component 3. As can be seen from the previous text, the electronic authentication module 2 sends open and close signals to the controller 5, and the drive component 3 is responsible for physically opening and locking.
[0036] The cover plate 6 is fixedly installed on the first surface of the lock body 1. The cover plate 6 is used to close the cavity on the lock body 1 and isolate the drive assembly 3 and the locking rod 4, preventing the drive assembly 3 and the locking rod 4 from being exposed. The mechanical locking lock 7 is installed on the cover plate 6. The working end of the mechanical locking lock 7 can extend into the blind hole in the lock body 1. That is, the cover plate 6 can be opened and closed through the mechanical locking lock 7.
[0037] Please see Figure 4 The mechanical lock 7 has a storage chip 71 inside, which is used as a security audit mechanism. The details will be introduced later.
[0038] Please see Figure 2 and Figure 5The drive assembly 3 includes a drive disk 31, a motor 32, and a connecting rod 33. The drive disk 31 is located in the cavity on the lock body 1 and is rotatably connected to the lock body 1. The motor 32 is also installed in the cavity on the lock body 1. The motor 32 is connected to the drive disk 31 through a gear pair, so that when the motor 32 rotates, it can drive the drive disk 31 to rotate.
[0039] The two ends of the connecting rod 33 are connected to the drive disc 31 and the locking rod 4 respectively. When the drive disc 31 rotates, the connecting rod 33 swings, which in turn drives the locking rod 4 to slide back and forth along its own axis.
[0040] In some possible implementations, there are three linkages 33 and three locking levers 4.
[0041] In some possible implementations, the drive disc 31 is equipped with an operating handle 34, the purpose of which is to facilitate manual operation. As can be seen from the preceding text, when the cover 6 is opened, it means that manual opening is required. At this time, by pushing the operating handle 34, the drive disc 31 can be rotated and the locking lever 4 can be slid. By adjusting the direction of rotation, the drive disc can be opened and closed.
[0042] Please refer to Figure 6. The power supply for the electronic authentication module 2, drive assembly 3 and controller 5 is provided by a power supply module installed on the lock body 1. In some examples, the power supply module includes a battery 81, which is generally a lithium battery.
[0043] The battery 81 is powered by a solar panel, which is mounted on the first surface of the lock body 1. To protect the solar panel, a transparent protective cover can be added to it.
[0044] Alternatively, a wireless induction coil can be added. The wireless induction coil is located inside the lock body 1. The function of the wireless induction coil is to charge the battery 81 in a non-contact manner.
[0045] In some examples, the battery 81 is located inside the cavity, and the solar panel and wireless induction coil can be deployed in the groove on the cover plate 6, with a transparent protective plate installed on the groove for protection.
[0046] In some examples, a contact sensor 61 electrically connected to the controller 5 is also added. The detection end of the contact sensor 61 abuts against the inner wall of the cavity on the lock body 1. The contact sensor 61 is mounted on the cover plate 6 and its function is to send a signal when the cover plate 6 is opened. This signal can be used to determine whether the cover plate 6 is opened normally or illegally.
[0047] The determination method here is whether there is an opening step corresponding to the electronic authentication module 2. If the opening step exists, then the signal generated by the contact sensor 61 indicates that the cover 6 is opened normally; otherwise, it indicates that the cover 6 has been opened illegally.
[0048] Here, the signal generated by the contact sensor 61 is generally sent to the cloud via the controller 5 for judgment. At the same time, the actions (opening and closing) of the drive component 3 described above are also sent to the cloud for recording.
[0049] The following description, in conjunction with the usage process, further illustrates that the intelligent door lock system for highway pipeline wells disclosed in this application requires the use of an electronic key. The electronic key is a terminal that integrates multiple functions such as communication, identity authentication, and charging, while also providing the functionality of a mechanical key.
[0050] When in use, first bring the electronic key close to the electronic authentication module 2 on the lock body 1. The two complete communication and identity authentication. Then, the electronic authentication module 2 sends an opening signal to the controller 5. After the controller 5 sends a start signal to the drive component 3, the locking lever 4 moves to complete the opening action.
[0051] The electronic authentication module 2 communicates with the electronic key via NFC or Bluetooth. Specifically, the electronic key sends identification information, the electronic authentication module 2 verifies the received identification information, and sends an unlock signal to the controller 5 after successful verification.
[0052] When closing, bring the electronic key close to the electronic authentication module 2 on the lock body 1 again.
[0053] When the electronic unlocking method fails, bring the electronic key close to the mechanical lock 7 on the lock body 1. At this time, the electronic key will read the key stored in the storage chip 71 inside the mechanical lock 7, and then send the key to the cloud. After receiving the key, the cloud will verify it. If the verification is successful, it will send an unlocking command to the electronic key. At this time, the mechanical key inside the electronic key will extend, and the staff can use the mechanical key to complete the unlocking action.
[0054] The storage chip 71 (electrically connected to the contacts) forms a circuit with the circuit inside the electronic key through the contacts on the mechanical lock 7 and completes the above data communication work. After the mechanical key inside the electronic key extends out, it is directly inserted into the mechanical lock 7. When the circuit is broken, the mechanical key automatically retracts into the electronic key.
[0055] The electronic authentication module 2 uses chips including the MOD208 (with a built-in SHA-256 encryption engine and a true random number generator (TRNG), supporting key storage and tamper-proof NVM) and an electronic ID card chip (integrating a microprocessor (MPU), a cryptographic coprocessor (CAU), and secure storage (EEPROM), supporting two-way authentication and data encryption). Its core function is to authenticate the electronic key mentioned above. The controller 5 can use an ARM architecture chip (WT2801, with functions such as motor drive and sensor management). The battery 81 has a built-in power management chip (ADI LTC4040) responsible for managing charging and discharging.
[0056] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
