Community intelligent passing control system and method based on narrow band Internet of Things

Abstract

The invention provides a community intelligent passing control system and method based on narrow band Internet of Things and belongs to the technical field of Internet of Things. The system is an intelligent wireless control system composed of a narrow band Internet of Things (NB-IoT) communication technology, a network technology, a cloud technology and a control technology and is applied, but not limited to the fields including elevators, access control, parking lots and the like of a community. The system is a whole set of solution for community intelligent passing. The system comprises a mobile terminal (APP (Application) or a Wechat applet) of a user, a property management platform, a cloud server, an NB-IoT communication module, a controller, an expansion board, a license plate recognition camera and a two-dimensional code display device. Compared with other methods, the system has a plurality of incomparable advantages of massive connection, deep coverage, ultralow power consumption, low cost, stability and reliability and the like; the system is an only technical solution for realizing effective communication in scenes with relatively weak signal coverage; and furthermore, an owner can pay property management fee, car parking fee and the like through a cell phone, and troubles that the owner goes to a property management center back and forth are avoided.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a system and method for intelligent traffic control of a residential area based on the narrowband Internet of Things. Background technique [0002] At present, the Internet of Things communication technology can be divided into two categories in terms of transmission distance: [0003] Short-distance communication technology, representative technologies include Zigbee, Wi-Fi, Bluetooth, Z-wave, etc., typical application scenarios such as smart home; [0004] Wide-area network communication technology is generally defined in the industry as LPWAN (low-power Wide-Area Network, low-power wide-area network), that is, wide-area network communication technology. LPWAN technology can be divided into two categories: one is the technology working in the unlicensed frequency band, such as Lora, Sigfox, etc. Most of these technologies are non-standard and custom ...

Problems solved by technology

[0006] At present, various solutions for non-contact control of elevator floor selection, access control and parking lot management are based on different communication methods; using short-distance communication technologies Zigbee, WIFI, Bluetooth, etc., the disadvantage is that the communication distance is short and remote control cannot be realized. , the network is complex, the point-to-point connection speed is slow, and the number of devices connected is limited; using Lora, Sigfox, etc. in the wide area network communication technology, although the communication distance is long and the coverage is wide, the disadvantage is that a self-built gateway or base station is required, and the network is complex. There is a delay in the signal; while using the more mature 2G / 3G cellular communication technologies such as GSM, CDMA, and WCDMA in the wide area network communication technology, the operator's existing base station is used, although it solves the problem of long communication distance / wide coverage / simple networking The problem, but the disadvantage is that because it covers medium and high rates, the signal coverage is not strong, and the signal in the elevator shaft and underground parking lot is very weak or almost non-existent, so data transmission cannot be realized

Therefore, when the above various solutions are applied to the site of this case, the user experience will be poor, and the deployment cannot be realized or abandoned by users after deployment.
