Electronic storage locker is more and more popular recently,and more and more people consider the safety. For the current normal lock for electronic locker on the market, give the power to the lock/send a unlock command to open the lock,the lock will be opened immediately. At this time, if someone stands in front of the locker door, he or she will be easily injured. And more and more customers have given us feedback about this problem, so our R&D team designed a lock (KR-S99S) to solve this problem. KR-S99S with push to open function: give the power to the lock, the lock will keep closing until the user push the door for opening, at this point you won't have to worry about the door hurting the user. This lock is driven by solenoid,available in 12V and 24V. We also have a control board that goes with this lock. If you are interested, we will send you samples for testing. If you prefer a motor-driven lock and would like to add this feature, please let us know. We can also make motor-driven locks with this feature.

As we all know, property safety is becoming a hot topic of concern. When you go out,travel, shop or others, taking care of your belongings is a priority. Therefore, storage cabinets are becoming more and more common in people's life. You can see storage cabinets in almost every public scene. However, the problem is that the storage cabinets are heavily occupied, which seriously reduces the utilization rate of the storage cabinets. How to solve this problem? Let me introduce you to our smart RFID lock -- unlock after a while,such as 2 hours,4 hours;8 hours... Scene 1: Swimming, we know that when we swim, we have to keep our mobile phones, wallets, clothes and other things in the locker. Someone may only play for 2 hours, but they occupy the locker for 1 day, which leads to a very low use rate of the locker. If we set up lockers that can only be used for a certain period of time (e.g. 2 hours, 4 hours...) After that time, the lock automatically opens,so that tourists must plan their use time reasonably, thereby greatly improving the utilization rate of the lockers. Scene 2: Supermarkets, supermarkets have traffic every day. When you shop, you need to store your parcels in the locker. If it happens to be the peak of the crowd, the customer does not take out the parcels in time, which means that a cabinet can only be used once a day. If we set the package storage time, it can be easily served to the next customer. Are you interested in the above designs? Our lock can realize automatic unlocking function,through this function, the probability of the locker being occupied can be greatly reduced. If you are facing similar problems, please contact us, or you have other ideas, we will be happy to communicate with you.

Self-driving delivery vehicles are becoming more and more popular and more common. Through it, we can get takeaway more safely and conveniently, and the store can save staff and complete orders faster. In addition to takeaway, we can also receive express packages through unmanned delivery vehicles. Unmanned delivery vehicles can reduce human contact and strengthen epidemic protection. We are believe that unmanned delivery vehicles will continue to bring us more surprises. Many of our customers are completing the project of unmanned delivery vehicles, hoping to make their own efforts for epidemic prevention. So what can Kerong do for unmanned delivery vehicles? We have waterproof locks that can be used in outdoor environments, allowing unmanned delivery vehicles to work without fear of wind and rain; Our infrared strips can tell merchants and customers: Has the unmanned delivery vehicle placed an item? and whether the item was taken? Can also be used with our control panel. We are doing our best to help our clients complete this meaningful project together. Innovation changes lives!

Does it have shared scooters in your city? Do you know how to manage the shared scooters? Can you imagine a use for a shared scooter combined with the electronic lock? Let me tell you! The electronic lock can lock the shared scooter in the parking pile. Our lock can not only detect whether the lock hook of the scooter is correctly hooked, but also detect whether the scooter is really hooked, because our lock has a door magnetic detection function. The feature also prevents people from using the shared scooter maliciously or taking it for themselves.Our electronic locks also have four signal modes to choose from. If the lock in signal mode is used, the lock will not be opened immediately after the parking pile is powered back on after power failure, so that the scooter will not be suddenly unlocked without people. With the use of our lock and control board, customers can also make their own app. Users of scooters can also use scooters by scanning the Qr code, and check the battery and riding time of scooters on the APP. The App also calculates how long the user has been using the scooter, and can calculate the use fee based on the time spent using the scooter. The electronic lock can also be used to lock the scooter's battery and is mounted on the cover of the battery case. If you are worried about the lock being shaken open while riding a scooter, we also have shockproof locks that won't be blown open on rough roads. Therefore, electronic lock is still very practical and common for scooter sharing or bike sharing applications. If you also want to develop this project, we have enough experience and professional R & D team to help you.

As its name suggests, last mile delivery refers to the last leg of the delivery process. It involves the delivering of goods from a warehouse or port to the final destination. Today, with the expansion of epidemics around the world, the last mile delivery is more effective, faster and more convenient than ever, and it can also better avoid human contact and bacterial infection. Therefore, more and more people choose to use express cabinets/lockers to receive last mile parcels. When it comes to express cabinets/lockers, it consists of cabinets/lockers, locks, control boards system accessories, software, etc. We are proud to provide customers with a variety of last mile delivery solutions to meet various needs. As we all know, express cabinets/lockers are divided into indoor and outdoor uses, corresponding to lock accessories, there are also waterproof versions and non-waterproof versions; for lock types, there are electromagnet type and motor type. Regardless of the type, we can provide a complete solution, such as electromagnetic locks, electronic motor locks, waterproof locks, non-waterproof locks, 304 stainless steel strong locks, high holding force locks and etc. As for the control system, there are different type control boards to match with, no matter to control one lock, two locks at the same time, three locks at the same time, 16 locks or more locks, all are supported. Besides the locks and control boards, there are also infrared sensors, LED detection status light to help to instruct the status of locks and lockers/cabinets to let the system know whether the locker/cabinet is empty or occupied. Under such a solution, the last mile delivery is smart and efficient, and it can also solve the inconvenience caused by factors such as storage status and pickup time.

Nowadays more and more people knows about the parcel locker in the community, shop, park etc, and more and more people start to use it. Are you familiar with it? And now convenience becomes a focused point in peoples life, then the home parcel locker occurred. As we know that there is letter box in the front of our home, the messenger put the letter into the box through a gap, then the owner come back and open the box by mechanical key and take the letter out. The home parcel locker works similar with this way, the delivery people put the package in the locker, the owner come home and take the package out. What is the difference? The current solution is more intelligent, we can open the locker by card, password, fingerprint, even by phone keyless solution. And it can work with IOT, cloud, sever, the owner can know whether the package is put into the locker and when the package is delivered by the APP or message. What kind of things can be delivered into this kind of locker? All kinds of packages which you purchased online, take-out food, vegetables, fresh food etc. If you need, you can make the locker to be refrigerated, then the fresh food, cold drinks can be delivered in that locker. Also you can make the locker to be different size, bigger size for big package, small size for small package. And what if the benefit of it? No need to go away to take your package from the multiple parcel lockers because it is in the front of your home door. No need to concern when the package arrives but you are not at home. No need to concern that someone will take the package from your home door. Do you have an idea to build this kind of locker for your own home? Please share it with us, we communicate it together.

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.
