Its advantages are simple structure, low cost, high reliability, no need for power support, suitable for some of the security requirements are not particularly high, limited budget and no need for complex management of small server cabinet scenarios. But the shortcomings are also more obvious, such as the key is easy to lose or be copied, the management of a large number of keys is more cumbersome, can not be realized remote control and monitoring, difficult to accurately record the time of the switch locks and personnel and other information. Mechanical combination locks: By setting a numerical code to control the opening and closing of the lock, compared with traditional mechanical locks, it improves security to a certain extent and eliminates the need to carry and manage a large number of keys. However, the code is easy to be forgotten or leaked, and also can not realize remote management and accurate operation record function. Electronic Lock Control Management Electronic combination lock: using electronic components and password verification technology, by entering a preset numerical password to unlock. It has the features of modifiable password and relatively high security, while some electronic combination locks also have the functions of anti-picking alarm. It is suitable for the scenarios that have certain requirements for security and want to control the access of personnel through password management. However, if the password is known or leaked by many people, there is a certain security risk, and generally do not have remote control functions. Swipe card lock : using radio frequency identification (RFID) and other technologies, by reading the authorized card to open the lock. With the advantages of easy to use, fast, can realize a card multi-lock or multi-card lock flexible configuration, easy to manage personnel rights. Commonly used in places where personnel mobility is large and frequent switching of cabinets is required, such as the operation and maintenance areas of data centers. However, the card may be lost or stolen, need to be properly stored, and it is difficult to realize remote real-time monitoring. Fingerprint lock: With the help of fingerprint identification technology, only authorized personnel with pre-recorded fingerprints can open the lock. With a high degree of security and uniqueness, it avoids the risks of lost or stolen keys or cards as well as password leakage, and also improves the convenience and efficiency of operation. It is suitable for important server cabinets with very high security requirements and strict identification of personnel. However, fingerprint identification may be affected by finger oil, humidity and other factors, resulting in recognition failure, and the cost of equipment is relatively high. Intelligent lock control system: It consists of intelligent electronic lock, intelligent electronic key and lock control management software. Intelligent electronic locks installed in the server cabinet, can be unlocked through the electronic key operation, and management software can locks, personnel, authority, locking time and other unified management and monitoring.

Kerong Electronic Smart Lock Technology Co., Ltd. will take you to understand where passive locks are used? As a technical concept, passive locking has a wide range of applications in different fields. Its core feature is that the locking function can be realized without external active intervention through preset rules or conditions, which makes passive locking play an important role in multiple scenarios. In a warehouse management system, passively locked warehouse management locks down specific inventory or warehouse areas through automation rules or system settings to prevent operations or changes under certain conditions. This approach not only improves the efficiency of inventory management, but also reduces human error and ensures inventory accuracy. The system automatically triggers the locking mechanism, making inventory management more intelligent and automated. In the field of locks, passive locks also play an important role. Unlike active locks, which require external forces (such as keys, passwords, etc.) to open, passive locks typically rely on physical structures or environmental conditions to achieve locking. For example, a common bicycle lock is a passive lock that requires the user to manually thread the chain through the wheel and turn the key to lock, which effectively prevents unauthorized access. In addition, passive mode-locking technology is also widely used in the field of fiber lasers. Passive mode-locked fiber lasers can use the intensity dependence of nonlinear optical effects in optical fibers or other components on the input pulse without the use of active components such as modulators, and achieve phase locking of each longitudinal mode, thereby generating ultrashort optical pulses. This technology has the advantages of simple structure and narrow output pulse, and has a wide range of application prospects in medicine, spectroscopy, laser ranging, lidar detection and other fields. In addition to the above-mentioned areas, passive locks also play an important role in industrial automation, smart home, and other fields. Through preset rules and conditions, passive locks can flexibly set locking conditions to meet the needs of different scenarios. For example, in a smart home system, a passive lock can be linked with other smart devices to achieve more intelligent home control. As a supplier of passive lock source factory, Kerong plays an important role in dozens of countries and dozens of industries around the world. Kerong passive lock is of good quality and low price, welcome customers with needs to leave us a message, we welcome OEM, ODM orders, thank you.

There are many people who don't know much about industrial passive locks, and today Kerong passive lock experts will take you to understand. Industrial passive lock is a lock applied in the industrial field, and its main feature is that its locking mechanism requires the action of an external force to trigger. Compared to active locks, passive locks tend to be more straightforward in structure and relatively low maintenance, making them widely used in industrial environments. From the definition point of view, there is no unified and specific definition of industrial passive lock, but it can usually be understood as a new type of security bolt or lock used in the process of industrial collection of raw materials, processing and production. These locks are mainly composed of chains, chain sockets, sliding columns, chain plugs, lock seats and lock bodies, etc., which have the characteristics of simple structure, convenient assembly and disassembly, and beautiful and generous. They can be used as the second line of defense for doors, and are widely used in homes, shops, warehouses and specific insurance places, especially in industrial environments, such as banks, warehouses, maritime, docks and other places, to provide customers with high-quality anti-drilling and anti-theft solutions. In the application of industrial passive locking, the locking mechanism can be implemented in a variety of ways. For example, some passive locks may require manually threading the chain through a specific part and turning the key to lock, which is intuitive and requires no learning curve, making it more comfortable for those who are used to traditional ways of operating. At the same time, because passive locks do not rely on complex electronic components, they are more reliable in harsh environments (such as high temperature and humidity) and are less prone to failure. In addition, industrial passive locks also have the characteristics of wide adaptability. Through different designs and material options, passive locks can meet the needs of different industrial application scenarios. For example, in places that require high-strength security protection, passive locks made of high-quality zinc alloy and high-strength stainless steel materials can be selected; In places that require intelligent management, passive locks that integrate sensors, processors and other intelligent components can be selected to achieve real-time perception of environmental changes and fine control. In general, industrial passive locks have a wide range of application prospects in the industrial field due to their simple structure, low maintenance cost, high reliability and wide adaptability. Kerong is an electronic smart lock company established for more than 20 years, and industrial passive lock is one of the company's core products. We provide high-quality smart passive locks to all walks of life, welcome customers from all over the world to buy Kerong brand, we accept OEM/ODM orders, welcome to leave us a message. Thank you.

Unlocking Faults A.Recognition problems 1. Fingerprint recognition failure: The fingerprint recognition module may not recognize fingerprints accurately due to wet fingers, dirt, or finger injuries. For example, if the user's hands are sweaty or have just touched a sticky substance, the fingerprint's pattern may not be read, thus making the unlocking fail. In addition, after the fingerprint recognition module has been used for a long time, the sensor's surface may be worn out or stained with dust, which reduces the recognition accuracy. 2. Password Recognition Failure: If the user enters the password incorrectly too many times, the lock may enter the security lock state, and the lock cannot be unlocked by the password temporarily. At the same time, the password input device (such as keys) may be faulty, such as key jamming, poor contact and so on, so that the input password can not be correctly transmitted to the lock control system, resulting in failure to unlock. 3. Proximity card recognition failure: Proximity cards may not be recognized because they are demagnetized, damaged or have poor contact with the lock's sensing area. For example, if the proximity card is placed together with a device with magnetic field such as a cell phone, it may be demagnetized, thus affecting the unlocking function.   B. Mechanical structure problems 1. Lock cylinder failure: the mechanical structure inside the lock cylinder may be due to long-term use and wear and tear, deformation or foreign objects into the situation. For example, wear and tear of the spring inside the lock cylinder may lead to the key (if there is a spare mechanical key) can not be inserted or rotated properly, affecting the lock. In addition, dust, small particles and other foreign objects into the lock cylinder, may also block the lock cylinder channel, so that the lock cylinder can not work properly. 2. Lock tongue failure: the lock tongue may be subject to external impact or long-term use of mechanical fatigue and deformation, can not be ejected or retracted. For example, the mailbox in the transportation or installation process by the collision, may lead to the lock tongue position offset, can not be normal pop-up lock mailbox. Failure of Energy Harvesting and Power Supply A. Insufficient energy harvesting 1. Solar Energy Harvesting Problems: If the electronic passive lock relies on solar energy harvesting, the solar panel may not be able to harvest the sunlight effectively because it is blocked (e.g., covered by leaves, dust or other objects). In addition, in an environment with insufficient light (e.g., in a dark corner for a long time or in bad weather), the energy captured by the solar panel may not be able to meet the normal use of the lock, resulting in limited functionality of the lock. 2. Mechanical energy collection problem: For locks relying on mechanical energy collection, such as locks that collect energy through the opening and closing of the mailbox, if the opening and closing frequency of the mailbox is too low or the action is too gentle, it may not be able to collect enough energy. In addition, the mechanical energy harvesting device itself may malfunction, such as a decrease in energy conversion efficiency or damage to mechanical components, affecting energy harvesting. B. Failure of energy storage components 1. Aging or damaged batteries: If the energy storage batteries (such as supercapacitors or lithium batteries) in the lock are aging, their capacity will gradually decrease, resulting in insufficient stored energy to provide sufficient power support for the lock. The battery may also be damaged due to overcharging, over-discharging or short-circuiting, affecting the normal power supply of the lock. 2. Supercapacitor failure: The supercapacitor may have problems such as leakage, decreased capacity or internal short circuit. For example, if the lock is not used for a long time, the supercapacitor may lose power due to self-discharge, or there may be an internal short circuit due to quality problems, resulting in the inability to store and release energy properly. Communication Failure A. Signal interference problems 1. Bluetooth communication interference: If the electronic passive lock uses Bluetooth communication technology to communicate with external devices (such as cell phones), other Bluetooth devices, Wi - Fi signals or electromagnetic interference sources in the surrounding environment may interfere with the Bluetooth signals, resulting in unstable or interrupted communication. For example, Bluetooth signals may be interfered with in signal-intensive office spaces or environments with a large number of electronic devices. 2. Interference from other wireless communications: For locks that use other wireless communications such as ZigBee, NFC, etc., they may also be interfered with by other wireless signals in the environment. For example, NFC communication may be interfered by nearby metal objects or other NFC devices, affecting the communication effect. B. Communication module failure 1. Hardware damage: Communication modules (such as Bluetooth chips, NFC chips, etc.) may fail due to static electricity, overheating or physical damage. For example, in thunderstorms or more static environments, the communication module may be broken by static electricity, resulting in failure of normal communication. 2. Software problems: The driver software or firmware of the communication module may have errors or incompatible versions. For example, when the cell phone system is updated, it may be incompatible with the communication software of the lock, resulting in the inability to establish a communication connection or abnormal communication function. Waterproof, Dustproof and Environmentally Adapted Faults A. Waterproof Problems 1. Damaged seals: The seals (such as rubber seals) of electronic passive locks may lose their waterproof function due to long-term use, aging or damage by external forces. For example, the seal may be worn out and ruptured after many letterboxes are opened and closed, and rain or moisture will enter the inside of the lock body and damage the electronic components. 2. shell damage: lock shell if cracked or broken, will also lead to waterproof performance decline. For example, the letter box is hit or used in harsh environments (such as expansion rupture after being covered by ice and snow), may make the lock shell damage, thus affecting the waterproof effect. B. Dustproof problem 1. Vent blockage: some electronic passive locks for heat dissipation or other features may be designed vents, these vents if there is no effective dust control measures, dust will enter the lock body inside, accumulated in the electronic components, may lead to short circuit, poor heat dissipation or affect the normal operation of mechanical components. 2. Poor overall dustproof design: If the overall design of the lock does not fully consider dustproof, dust may enter the lock body through various gaps, affecting the performance of the lock. For example, in a sandy and dusty environment, dust can easily enter the lock cylinder, resulting in poor cylinder operation. C. Temperature adaptation failure 1. Cold temperature failure: In cold environments, the performance of batteries or energy storage components may decline, resulting in reduced power output. At the same time, some electronic components may experience parameter changes or start-up difficulties due to low temperatures. For example, the liquid crystal display (if any) may have a blurred display or fail to display properly at low temperatures. 2. High Temperature Failure: A high temperature environment may cause electronic components to overheat, affecting their performance and life. For example, chips may crash or run slower when operating in a high-temperature environment for a long period of time, and high temperatures may also accelerate the aging of seals and plastic parts.
