Wireless IOT access control system: no wiring, reliable, energy-saving

wireless access control products have emerged through FSK, GPRS, Bluetooth, ZigBee and other transmission methods through the continuous evolution of technology since their birth. With the rise of IOT technology, IOT access control products have received widespread attention in the security industry

access control system, also known as access management control system, is a digital intelligent management system that manages the access of relevant personnel. Today, with the development of science and technology, the access control system has developed into a modern and fully functional management system, which has gone beyond the simple management of door locks and keys, and can also help to standardize the management of internal personnel of the company. It can not only automatically record the access of personnel at all times, restrict the access area and time of internal personnel, politely refuse uninvited guests, but also effectively protect property from infringement. Therefore, at present, the access control management system has become an extremely important part of the security system, which is widely used in the management of various room doors, gates and pedestrian passages, such as intelligent buildings, intelligent residential areas, offices, hotels and so on

traditional access control solutions connect and control through cables arranged to each door point. However, as the projects are carried out one by one, more and more peers and customers in the industry begin to realize that the wired system itself has many cables, and the installation and construction are troublesome. For example, the traditional locks (electric plug-in lock, magnetic lock) are not beautiful, poor reliability, unable to use after power failure, troublesome maintenance and other defects

therefore, many powerful access control enterprises are exploring new products that can not only meet the stringent requirements of the security system for access control, but also avoid many defects of the current wired access control system. Wireless access control is gradually being recognized and applied

development history of wireless access control

people choose wireless access control products mainly to reduce the complexity of wiring. Because the access control has the requirement of centralized management, each door point must communicate with the center. If wireless communication is selected between the door point and the center, the communication line between the door point and the center can be omitted, which is very attractive in some occasions with inconvenient wiring

the first generation of wireless access control was born under the above technical background. This kind of equipment mainly communicates through the free frequency bands specified by the state, such as rf315m and rf433m. The communication technology used is relatively simple. Generally, basic wireless modulation methods such as FSK or fmk are used. The frequency point is fixed. When multiple devices work together, there will be mutual interference, and the communication rate is low, generally between 300BPS and 1200BPS. Because the technical means are relatively simple, there are generally problems of poor communication stability and reliability in use, and such products have gradually faded out of the market

the concept of wireless access control is proposed with the development of technology, because the first generation of wireless access control cannot meet the needs of some specific places and industries in terms of communication and transmission distance. Therefore, some access control manufacturers bind modules and door controllers together, and control signals are wirelessly transmitted through connected and mobile networks through SMS or GPRS, so as to achieve the purpose of long-distance signal transmission. However, due to the collection of equipment costs, monthly rent and other related fees, the use cost of wireless access control is high, and the signal transmission delay through the GSM network is large, and the performance is not ideal (the communication rate is generally only Kbps, and the speed is unstable), so that wireless access control products are currently only limited to occasions and industries with certain needs

at present, some wireless access control products developed using Bluetooth, ZigBee and other short-range wireless technologies are gradually being recognized and applied by the market. Due to the characteristics of Bluetooth and ZigBee technologies, these wireless access control products have been relatively excellent in the stability of signal transmission, ideal speed (generally up to 1Mbps), and convenient device groups, so they are gradually being valued by the industry

at the same time, the wireless IOT access control system with wireless IOT technology has also received widespread attention in the market. It is predicted that IOT will become a technology that will change people's lives like the Internet in the future, and the application of IOT technology to wireless access control will undoubtedly seize the highland of wireless access control technology in the future, and the market prospect will be very huge. Unlike wireless access control, which only uses Bluetooth and Zig spring coefficient bee technology for wireless signal transmission, IOT access control focuses on intelligent perception and low power consumption of access control. Although Bluetooth and ZigBee are also low-power short-range wireless transmission technologies, they are still too power-consuming in battery powered IOT access control systems

wireless IOT access control system: no wiring, reliable and energy-saving

the access control system has been accompanied by a large number of wiring since the first day of its birth. A complete access control system is composed of eight modules: card reader, controller, electric lock, door switch, door magnet, power supply and management center, and each module needs wiring. At the same time, the front, back and top of the door frame and the top of the door should be perforated to install equipment. Therefore, the tedious construction is a very intuitive problem

wireless IOT access control simplifies the door equipment to the extreme: a battery powered lock. There is no need to install any auxiliary equipment around the door except for the opening and locking on the door. The whole system is simple and clear, which can greatly shorten the construction period and greatly reduce the cost of later maintenance

frequency hopping and encryption are another core of wireless access control. A big difference between wireless and wired is that wireless signals are transmitted in the air, so they are easy to be interfered by the outside world and easily captured by the outside world. Therefore, security and reliability can be said to be the lifeline of wireless access control products

the security and reliability of wireless IOT access control system are mainly reflected in the following two aspects: the security guarantee of wireless data communication and the stability of transmitted data

the wireless IOT access control system uses intelligent frequency hopping technology to ensure that the signal can quickly avoid interference. At the same time, the dynamic key and AES encryption algorithm are used in the communication process. Even if it is the same instruction, the communication packets transmitted in the air are different every time, so that the listener cannot intercept. However, for wireless technology, packet encryption technology can be understood and accepted, while wireless anti-interference ability is always a topic that cannot be bypassed. To solve this problem, the wireless IOT access control specially designed the offline working mode, which is a working mode to ensure that the door can be opened normally even after the wireless is interfered and fails or the central system is down. Taking the wireless door lock as an example, when the wireless communication fails, it is equivalent to an unconnected hotel lock, and the door can still be opened and closed normally (consistent with the opening authority of the time), and the user does not feel the difference between offline and online, The only difference is that when offline, the card swiping data is not transmitted to the center immediately, but is temporarily locked and automatically uploaded after the communication returns to normal

wireless IOT is an ultra-low power product, which will make the battery power supply life longer; Only with battery power supply, it is possible to be completely wireless. The communication speed of the wireless IOT access control system has reached 2Mbps. The faster the communication speed means that the shorter the signal transmission time in the air, the less power consumption. At the same time, the lock used by the wireless IOT access control system only consumes power when opening and closing the door. The static current of the whole wireless IOT door lock is only 20ua. If the door is opened and closed 100 times a day, the battery can be used for 2 years without replacement

comprehensive intelligence 1 disperses the perception of capital and resource advantages to a certain extent.

after years of development, the access control system has long been unable to meet the simple functions of opening and closing doors. In addition to the alarm functions of intrusion alarm, abnormal card swiping alarm, door unclosed alarm, immediate loss report, low battery alarm, it also has the functions of room temperature detection, light linkage, visual doorbell and so on. At the same time, the system can also support RF-SIM card to open the door

wireless IOT access control system, as a typical IOT application, extends the network to every door point, so that every door point has the function of intelligent sensing. At the same time, it has the advantages of safety, intelligence and then measuring one or more mechanical properties, energy saving and beauty. The construction of wireless IOT access control system can comprehensively improve the intelligence of security, real-time transmission of all information, traceability of all card swiping opening and closing information, and instant response of all alarm information. At the same time, it can also realize intelligent linkage with other Ba systems. Its overall construction cost and use cost are lower than that of conventional access control. It is a revolutionary product of IOT access control and an upgraded product of offline Hotel locks

the wireless IOT access control system can directly replace the existing wired or non connected access control system. For the office building system, the application of wireless IOT access control can significantly reduce the construction workload and reduce the use cost; For the hotel system, it can improve the intelligent level of access control. However, for any new thing, there are inevitably some doubts in the market. How to dispel users' concerns about the stability, reliability and security of wireless systems is the biggest problem in the current market promotion. Our project and base have been listed as the national rare metal recycling demonstration project, the national key industry revitalization and technological transformation project, the national urban mineral demonstration base and the national regional large-scale renewable resources recycling base. I believe that with the promotion of IOT technology and the launching of wireless IOT access control cases, wireless IOT access control system will be more and more popular with users. (end)
