Combined with computers and IoT, it enables intelligent door lock control and management, effectively addressing the shortcomings of traditional locks, such as cumbersome use and the inability to record information. Data collected by controllers is used for security monitoring and intelligent management. Door lock management must be modern, functional, user-friendly, and rational. The system should be mature and practical, with future scalability and upgradability, ensuring long-term usability, applicability, and adequacy. With the principle of being economical, practical, and appropriately forward-looking, the focus is on controlling system scale and cost, providing users with an economical, practical, and advanced intelligent system at the highest possible cost-effectiveness. 1. Overall Solution 1. Considering management and expansion factors, it is recommended to adopt a wireless networked intelligent door lock management system. 2. The wireless networked intelligent door lock management system is a "campus card" management system based on contactless card reading and writing technology. It consists of campus cards, door locks, network communication, and door lock management software. From a unified network platform, unified database, unified identity authentication system, data transmission security, various management system interfaces, and exception handling, the overall design ensures comprehensive intelligent performance across management systems and card-reading terminal devices. 3. System structure diagram is as follows: Wireless Networked Intelligent Door Lock Management System 4. The system uses a wireless interconnected star network structure, directly connecting to the LAN and the internet. It employs ZIGBEE wireless communication technology, offering low power consumption, security, and large network capacity. It eliminates the cost of wiring projects, and in cases of network short circuits or disconnections (including power lines), the door lock's opening function remains unaffected. Through the Zigbee wireless network, computers can easily extract door lock opening records and authorized card information. 5. Convenient use: Supports multiple opening methods, such as campus cards and keys. The considerate always-open/always-close function eliminates the hassle of frequent card swiping. When the main lock tongue (three square tongues) is not lifted and locked, the door can be opened without swiping a card, and no card check is performed (no response to swiping, saving more power). 6. Super real-time technology: Real-time upload of newly occurred event records ensures overall system real-time performance; real-time monitoring of door lock status, battery level, signal strength, etc. 7. Convenient mobile interconnection: Students can check door lock status via mobile phones, receive reminders for card replacement and loss reporting, monitor personnel entry and exit, and receive alerts for陌生人開(kāi)門(mén), achieving upgraded security monitoring. 8. Powerful log system: Detailed records of each door lock's opening and closing times, status, faults, etc. Information can be analyzed and processed by time period, department, etc., meeting big data management needs. 9. Convenient權(quán)限管理: Operations such as card replacement, data upload, and permission distribution can be performed quickly and easily over the network. Opening permissions can be flexibly allocated by area, building, level, etc. 10. Strong system scalability: To facilitate system integration, the wireless networked intelligent door lock management system provides open interfaces for easy connection with other systems and convenient management. 2. System Integration Implementation 1. Data synchronization: The wireless intelligent door lock management system can use the "campus card" to identify身份信息. When issuing campus cards at the campus card center, user information is synchronized to the door lock management system in real-time or at scheduled intervals via synchronization procedures. 2. The main role of the data gateway is to provide authentication basis for legitimate campus cards, effectively isolating the campus "card" dedicated network while connecting to the school's management dedicated network. 3. Changes in campus card data are synchronized in real-time to the data gateway, such as new users, loss reporting, unblocking, card replacement, cancellation, and modifications to important fields. 3. Data Security and Access Policies 1. Data access security measures: Establish trust boundaries between the campus card system and the intelligent door lock management system server, and between the application server and the database server. Based on these trust boundaries, users in the system have no reliable trust relationship with the database server and cannot directly access the database. This ensures that even in public network environments, the intelligent door lock management system database and the campus card center database information are protected from malicious access. 2. Policy-based database access control: In the system, each user has a different identity, and the database information they access is relatively fixed. At the business logic layer on the application server, different roles are designed with different access policies, so that when users access the database, they can only access limited database information. 3. Data backup strategy: The system must back up data and consider system recovery in case of disasters, quick system recovery during failures, and minimizing the impact of the backup process on system performance. The frequency of data backups and the retention time of data on backup media should meet the expected design goals. The backup strategy should include: selection of data content to be backed up, scheduling of backup times, choice of backup methods (e.g., full or incremental backup), and specification of backup devices or media. 4. Usage Effects 1. Campus security monitoring upgrade: Through door lock entry and exit records, real-time monitoring of dormitory personnel, return status, and alerts for陌生人刷卡. Students can check dormitory door lock status via mobile phones, achieving upgraded security monitoring. 2.

Category:Hardware & Tools/Wrenches/T-Handle Wrenches

Product Description:Ratchet WrenchDifferencesThe ratchet socket wrench is composed of main and auxiliary spline sockets of various sizes connected via the engagement of internal and external keys on articulated joints. Each spline socket features two differently sized spline through-holes.The movable handle allows for convenient adjustment of the wrench's working angle. This type of wrench is used for tightening and loosening screws, offering strong adaptability, ease of use, and low cost.A torque wrench, also known as a torsion or moment wrench, operates on the principle that torque is the product of force and distance. When tightening threaded fasteners such as screws, bolts, and nuts, it is necessary to control the applied torque to ensure the fastener is secure without damaging the threads due to excessive force. Hence, a torque wrench is used for such operations. First, set the desired upper torque limit. When the applied torque reaches this set value, the wrench emits a "click" sound or the joint bends slightly, indicating that the fastener is tightened and no additional force should be applied.The key difference lies in the fact that the torque of a torque wrench can be preset.The principle behind the "click" sound of a torque wrench is straightforward and can be understood in the following steps:1. The "click" sound indicates that the required torque value has been reached;2. The "click" is produced by the internal torque release mechanism, which consists of three components: a pressure spring, a torque release joint, and a torque push rod. more>
