Description
Technical Field
The invention relates to the technical field of Internet of things, in particular to a management system and a management method for an electric power ultrahigh river-crossing iron tower engineering construction project based on the Internet of things technology.
Background
In the construction process of the traditional building industry, due to wide personnel distribution, large site range and low informatization degree, the efficiency of management work is low, the safety and the construction quality of a construction site are difficult to ensure, and even safety accidents are caused frequently. Therefore, the search for a safer and more effective engineering management mode is urgent. With the rapid development of computer and network technology in recent years, the combination of the technology and various fields is more and more compact, and a new method and breakthrough are brought for realizing safety, high efficiency and high yield. As an indispensable technology in daily life and industrial production, the Internet of Things (IoT) refers to connecting any object with a network through information sensing equipment according to an agreed protocol, and performing information exchange and communication between the objects through an information transmission medium to realize functions such as intelligent identification, positioning, tracking, supervision and the like. The related key technology of the Internet of things is developed rapidly and is widely applied to the construction industry, particularly the application of the Internet of things technology in the aspect of engineering management and monitoring platforms provides more comprehensive guarantee for the safety of engineering construction sites and the product quality. New IoT connections are all industrial internet of things (IIoT) solutions, requiring low power wide area network (LPWA) technology to provide efficient connections, ubiquitous coverage, and competitive service payment models for low bandwidth solutions. Industrial internet of things applications may also require seamless coverage in remote environments where maintaining connections at all times consumes power and shortens the lifetime of solutions, narrowband internet of things (NB-IoT) technology is a promising solution for construction safety management in the building industry, etc.
Narrowband internet of things (NB-IoT) is a new wireless technology standardized by 3GPP in 2016. It rises rapidly as LPWA technology, supporting a large number of new industrial internet of things IIoT devices, including utilities, wearable devices, and industrial solutions. Each NB-IoT network cellular base station can support up to 5 thousand devices while greatly reducing power consumption and covering areas that cannot be reached by traditional cellular technology. The high network efficiency of NB-IoT also greatly reduces power consumption, allowing battery life to exceed 10 years. In addition, NB-IoT can penetrate deep into the ground and into enclosed spaces, providing 20+ dB indoor coverage, which is extremely useful in construction situations. NB-IoT infrastructure technology is less complex than traditional cellular modules, simplifying OEM design, development and deployment. At the same time, it provides the same reliable and true security and privacy functions as LTE mobile networks, including support for user identity confidentiality, entity identity verification, data integrity and mobile device identification.
The NB-IoT has obvious advantages in the application of the Internet of things, and is incomparable with the traditional cellular network technology and short-distance transmission technologies such as Bluetooth and Wi-Fi. Firstly, the coverage is wider, the NB-IOT has 20dB gain compared with the existing network under the same frequency band, and the coverage area is enlarged by 100 times. The method is suitable for regional construction management of construction sites; the support capability of NB-IoT for massive connections, and one sector of NB-IOT can support 10 ten thousand connections. While the power consumption of NB-IOT is lower, only 1/10 at 2G, the module cost has dropped to within $ 5. In terms of supporting big data, data collected by the NB-IoT connection can be uploaded directly to the cloud, while bluetooth, Wi-Fi, etc. technologies do not have such convenience. CMW 500-based 3GPP R14NB-IoTIn the positioning method of (Cat-NB2), in an NB-IoT system, the time delay estimation and positioning algorithm suitable for positioning the NB-IoT terminal mainly works as follows, in order to solve the problem that the precision of the traditional time delay estimation method is limited by the sampling rate under the single-path channel, the positioning is carried out by a two-stage time delay estimation method: the method comprises the steps of utilizing time domain autocorrelation of a narrowband positioning reference signal at different sampling rates to estimate integral multiple time delay, then converting the signal to a frequency domain on the basis of integral multiple time delay compensation, utilizing subcarrier phase differences to estimate decimal time delay, and breaking through system sampling rates to improve time delay estimation accuracy. Cross-zone positioning is performed in more than one physical resource block (prb).
Based on the background of rapid development and wide application of the internet of things, the information network technology is also applied to the management of engineering construction sites. By laying information acquisition equipment such as video monitoring and sensors on a construction site, a network is built to transmit data acquired by terminal equipment to a background, and a manager realizes full-range supervision on a construction site based on processed information, so that engineering construction management is more intelligent and informationized.
