During the COVID-19, contactless distribution developed well, which not only greatly reduced the risk of contact infection, but also improved work efficiency, which will also become a future development trend. For safety reasons, as early as a long time ago, some office buildings have required delivery personnel to hand over to the orderer without entering the building, and similar reminders that "takeaway and courier personnel are not allowed to enter" are used in residential quarters, and then special express delivery points have been set up in the community and office buildings. However, the single storage place is limited by the area, and it is placed in disorder. It is time-consuming to find and easy to lose, and the fundamental problem still cannot be solved. At this time, merchants seized the opportunity to add services to contactless distribution: in cooperation with self-service distribution cabinets, distributors put fresh food in storage and customers picked it up, this makes up for the shortage of ordinary express cabinets that cannot be kept fresh. In this way, it is more convenient for customers to pick up the goods, and the merchants do not have to be too limited by the delivery time. On the basis of ordinary goods, even food and vegetables can be centrally stored and picked up by self-service. Standardize the system and carry out standardized management, so that the quality of distribution services will be higher. The non-contact distribution under the COVID-19 situation ensures the health of customers, and at the same time makes the distribution more standardized, which greatly improves the work efficiency, and will naturally be welcomed by everyone. For a long time in the future, it is still necessary to do every detail of contactless distribution and keep up with the development trend. The fresh food distribution industry is highly competitive, and only by keeping up with the development trend can the competitiveness be improved. Take-out storage cabinets are one-time use and long-term use, making them the first choice for property management companies. The door is no longer cluttered, and it is restored to the previous clean and tidy; the gathering during pick-up has disappeared along with the scan code access of the takeaway cabinet. There is no need to delay. In terms of security, user privacy is well protected. Especially for single people, the elderly have no worries, no contact, no door-to-door, and pick up meals by code. This handover method that conforms to the living habits of the younger generation is affirmed. The service of fresh cabinets will extend from the core business area to the residential area, connecting work and life.

Solenoid locks also called electromagnetic locks. The terminal of a solenoid lock is actually a solenoid, which controls a simple mechanism for opening and closing the door. However, the action of the solenoid is through a series of command actions. When the occurrence can not be controlled, first measure the voltage transmitted to the electromagnet, while entering the switch door instructions (some for the electromagnetic card, some enter the password), to see if its voltage changes, such as changes, and the electromagnet does not move, the fault for the electromagnetic control part, should repair the electromagnetic control part or replace, otherwise the control part failure. Control part is more complex, it has two parts of hardware and software for control, some are also connected to the computer interface, personnel access query statistics, etc.. General control output voltage by the relay control output. First of all, see whether the relay has the sound of absorption, such as no, you can measure the voltage of the various parts of the relay control interface and driver parts are damaged, such as intact, you can further measure the working voltage of the relevant integrated circuit, reset port and clock oscillation part, such as no problem, generally for the software failure, which can only be contacted with the developer. If the relay has a suction sound, and the relay voltage is normal, then the relay contacts are damaged or sent to the electronic control part of the line break. Solenoid lock, in the lock body are provided with a main latch, vice latch, solenoid coil and armature located under the solenoid coil; outside the lock body are provided with a transmitter and a receiving circuit to provide current for the solenoid coil; in the latch is located in the vice latch position is provided with a blocking device; its characteristics are: between the main latch and vice latch is provided with a linkage device, the movement between them by the drive rod drive, fixed in the armature will drive the rod up the toggle lever. Solenoid locks applicable scenes can be used for lockers and toolboxes in institutions, office buildings, factories, schools, hospitals, etc. They are also suitable for intelligent communities. Intelligent pickup locker greatly improves the user's items storage, security and convenience. Solenoid locks can be used as intelligent cabinets, express cabinets, lockers, preservation cabinets, intelligent parcel cabinets, bathroom cabinets, intelligent self-take cabinets, factory cell phone storage cabinets, library storage cabinets, all walks of life are very suitable for use.

If you've ever been to a gym, then you've noticed that most gyms use keypad cabinet locks for their cabinets. Keypad lock is only one of the smart locks, there are many other types of smart locks. According to the different methods of unlocking smart locks can be divided into RFID locks, Bluetooth locks, fingerprint locks, combination locks, WiFi locks and so on. However, many people usually choose keypad locks over other smart locks. Compared with other smart locks, why can the keypad lock win? First, we can learn how the keypad lock works. The user enters the numeric code via the keypad and if the correct code is entered, the cabinet door lock or latch should release. Some keypad locks have an integrated security feature that locks the door for a period of time (usually 10 to 15 minutes) after multiple incorrect attempts to enter the code. Reasons for choosing a keypad lock 1.Convenience The keypad lock does not require a mechanical key and can be unlocked simply by entering a code. However, RFID locks do not require a mechanical key to open the lock, but any need to carry RFID cards, so that the RFID card becomes another type of key. The keypad lock achieves no need to carry any key. 2.Security Electronic keypad locks are every intruder's worst nightmare. They are nearly impossible to crack, and there is little chance that a potential intruder will guess the code to unlock your cabinet door. The keypad lock can be unlocked with a garbled code (entering a random code before and after the correct code), so that there is no fear of the correct code being leaked. 3.Cost There are keypad locks that can be on the expensive side, but other smart locks like Bluetooth locks biometric locks can be more expensive. And keypad locks help you save the expense of making a locksmith to unlock the door due to lost keys.

Radio Frequency Identification (RFID, electronic tags), Near Field Communication (NFC) are two of the more popular keywords, both belong to the tagging technology (Tagging). In essence, NFC is not different from RFID, both are used for signal transmission between two objects in close geographical proximity. RFID RFID is mainly used to identify and track the tags bound on objects, thus enabling the management of objects. Essentially, it is also a wireless communication technology that also transmits data through wireless electromagnetic waves. However, unlike general communication technologies it is used for purposes other than making phone calls, or sending text messages. RFID systems use tags (Tags) to identify objects. In addition to the tag, RFID systems also have a two-way wireless transceiver, known as the reader (Interrogator/Reader), to send signals to the tag, and read the tag feedback. The tag's identifiable distance does not change. Active RFID system generally refers to the active RFID tag, its identifiable distance will be reduced with the reduction of power. NFC NFC is a very common communication interface for cell phones today. It allows smart devices to exchange data by being in close proximity to each other. nfc devices can also communicate with a passive nfc tag, and this communication method is the same as RFID. nfc technology evolved from RFID technology, and in addition to the communication protocol, the nfc standard also specifies the data exchange format. The combination of an inductive reader, inductive card and point-to-point on a single NFC chip enables identification and data exchange with compatible devices over short distances. The difference between NFC and RFID (1) Working frequency band NFC can be understood as a subset of RFID technology, using the 13.56MHz frequency band, while RFID also includes other frequency bands. There are many RFID operating bands, 125KHz in the low band, 13.56MHz in the high band, 433.92MHz, 915MHz in the UHF band, and 2.45GHz in the microwave band, etc. (2) Communication distance NFC is called near-field communication, communication distance is really very close, no more than 0.1m. There are many types of RFID, and the identifiable distance is different. Like RFID access card, the recognition distance is similar to NFC. But for ETC such application scenarios, it requires a longer recognition distance. Long-distance RFID identification distance can reach dozens of meters or even hundreds of meters. (3) Application scenarios RFID whether active or passive, the main work is still used for the identification of objects, logistics, transportation, warehousing are widely used RFID technology to track goods. The NFC chip is more integrated and includes a reader and tag in one. In addition NFC's two-way communication capability has been enhanced. In other words, NFC can not only be used as a tag for identification, but also as a two-way communication method for data exchange. Currently NFC is most commonly used in the payment field. For NFC technology, even though QR codes can play the role of NFC in many scenarios in the field of payment and in the field of proximity object identification, NFC is not yet a necessary communication interface for smartphones. Although it is developed on RFID technology, but for different application scenarios, relatively speaking, RFID application scenarios are still much more than NFC.

In the age of the Internet, people's daily life has been inseparable from the cell phone, the most worried about going out is that the cell phone is not charged.

And what kind of lock is used in the cell phone charging lockers? You can use smart locker locks on your cell phone charging cabinet, such as RFID locker locks and combination locker locks, etc. You can also use electric control locks for centralized management control of cell phone charging lockers. No matter what kind of lock you choose, KERONG can provide you with the best locker solution. For smart locker locks, we have Bluetooth locker locks, card locker locks, password locker locks, fingerprint locker locks, etc. For electric control locks, we have solenoid locks driven by electromagnets and motor locks driven by motors.

Express cabinet delivery has become a trend in the world, but unlike other cabinet locks, this lock cannot be opened directly by password, RFID or fingerprints, because central controlled electronic locks have totally different structure and working ways. Usually this kind of lock needs to be integrated with the control board and software, and the lock is unlocked by issuing commands from the software. The most common communication methods on the market are TCP/IP and RS485, our lock controller is designed on the basis of RS485 communication. If you also use this way, it will be much easier to make integration, you only need a RS485-USB/232 converter to connect our controller KR-CU with your PC directly. For TCP/IP communication, we need to realize the conversion of the two signals, which requires our KR-BU control board, KR-BU connects router and KR-CU, achieving the conversion of TCP/IP and RS485 signal, KR-CU used to control electronic locks. In addition to the above two communication methods, we have also developed the Bluetooth communication. Our Bluetooth control board KR-BW can communicate directly with the APP, which will gradually become a trend. Another problem that customers are very concerned about is how to establish communication with our control board? Don't worry, we can provide you with test software to test the hardware part, and we will provide the protocol of the control board to help you complete the system integration. Due to the different requirements for locks in various projects, the number of cabinets that need to be controlled varies from a few to hundreds or even thousands, so many clients need to control as many locks as possible in one system. In response to this problem, we have also designed different controllers for customers to choose from. At present, the conventional control board can control 16 locks or 48 locks, but we can connect up to 10 control boards in series, which means a complete system can control 160 or 480 locks. However, some customers will also install our products on some special equipment, such as refrigerators, freezers, independent lockers, etc, one device only required very few locks, such as 1 or 2. In this way, if we still use our 16-way or 48-way control board, it will be a bit wasteful, and it will take up a lot of space, this requires our another small control board KR-SCU, one KR-SCU can control 1 lock only, there are max 100pcs KR-SCU board can connect in series, so one system can control max 100pcs locks. Now you should have a preliminary understanding about the control system of express cabinet. And KERONG can provide you with smart locker system solutions.

When you first encounter a smart digital lock, many people may ask this question. Why choose a digital lock? Let me tell you what the difference is between using a digital lock and a traditional cabinet door lock. There are two main differences. 1.Security Although smart locks are popular, there are still many lockers being used with traditional types of cabinet door locks that use only mechanical keys to unlock the doors. I am sure you all encounter these troubles. Unable to open the locker because the locker key you carry with you is lost. The locker door is opened and valuable personal items inside are stolen because the locker key is stolen. One of the main reasons for the increased demand for digital or biometric smart locks is the lack of need for mechanical keys! There are various types of digital locks. Most or almost all locks have digital PIN access and are matched with fingerprint or even RFID access to gain entry. And with advances in technology, some digital cabinet door locks also integrate Bluetooth access and use. When we use digital or RFID unlocked cabinet locks, both RFID and PIN access can be used to unlock the lock. What happens if we accidentally lose this RFID? This time we can directly remove from its lock set. Instead of spending more money to replace it with a new set. This is is the benefit of using digital access. And some digital cabinet door locks come with one-time passwords, garbled unlocking, and other features. So even if someone is next to you when you enter the access code, you don't have to worry about the code being compromised. Therefore, in terms of security, it will pass better compared to normal locking 2.Convenience Probably many times we find it troublesome to find the key, even if it is in your pocket. Some people may also leave their keys in the car or office. By providing different access, digital locks do not require a physical key to unlock the locker door. Different types of unlocking methods include: fingerprint / RFID (card) / digital PIN / key / Bluetooth / WiFi / 4G This means that you don't have to worry about not being able to access your personal belongings stored in the locker, even if you leave it without anything in your pocket.

Courier cabinets can often be seen in our lives, they are used to pick up, for example, we often see all kinds of courier cabinets in the community and office buildings, such as the intelligent courier cabinets of Feng Chao, Cainiao intelligent courier cabinets, Jingdong pick-up cabinets and so on, most of their appearance in addition to the color and design is not the same, its design to the use of external hardware materials are extremely similar. In this article we mainly talk about an important accessory of intelligent courier cabinet electric control lock. There are two types of electric control locks. One is solenoid-driven and called electromagnetic lock (also called solenoid lock). The other is motor-driven, called motor lock, compared to the electromagnetic lock it is more stable and lower power consumption. Solenoid locks are available in 12V and 24V voltage specifications, small in size, light in weight and usually made of stainless steel. The working principle is power on and unlock. Adopt the working mode of closing the door (power off) to lock and power on (12v) to trigger the unlock instantly. Working life up to 100,000 times. With mechanical emergency lever, can be unlocked manually in case of power failure. Motor locks have a wider range of working voltages than electromagnetic locks. They work in the range of 8V to 24V. We also have a low-voltage version of the lock that works from 3.5V to 8V and a high-voltage version of the lock that works from 23V to 25V. Motor locks are usually larger and heavier than electromagnetic locks. The working principle is signal unlocking and power on unlocking. Working life up to 200,000 times. With mechanical emergency lever, can be unlocked manually in case of power failure. Our motor locks have a door magnetic detection function to check if the cabinet door is closed well. And our motor locks are waterproof, with a waterproof rating of IP66. Application range of electric control locks Electric control locks can be used in lockers, letter boxes, depository cabinets, vending machines, cell phone cabinets, filing cabinets, file cabinets, drawers, meter boxes, lockers and other intensive boxes ...... are widely used in schools, mines, factories, banks, hotels, farms, bathing centers and other places.
