A data transmission method of a labor service real name system based on an NB-IoT mode

Abstract

The invention discloses a data transmission method of a labor service real name system based on an NB-IoT mode, the method comprises the following steps: first, the field client obtains the data of real-name labor service personnel from the cloud through the Internet, and transmits the data to the special board of real-name labor service system through the LAN; 2, a labor service real-name systemspecial board card pushes the data of the labor service personnel to a real-name system data acquisition device; 3, the real-name system data acquisition device judges the authority of the labor personnel according to the data of the labor personnel, and actually generates attendance records of the labor personnel; the real-name system data acquisition device transmits the attendance record to thelabor service real-name system special board card in real time. 4, real-time displaying and storing attendance records on a labor service real-name system special board, and passing the attendance records through the NB at a fixed time or in real time; the IoT network is delivered to the cloud server. The invention optimizes the problem that the labor service system is highly dependent on the wired Internet and the wired LAN, solidifies the software function into the special hardware, hardware the software function, and simplifies the installation and maintenance of the system.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a data transmission method of a labor real-name system based on NB-IoT mode. Background technique [0002] At present, the construction site labor data collection system is composed of gates, network equipment, and industrial computer. Through the network equipment, the gate and industrial computer form a local area network. The gate is integrated with a variety of personnel identity collection devices such as face recognition machines, fingerprints, and IC card control panels, which are used to identify and verify the identity of workers and control workers to pass through the gate. The industrial computer is used for information entry and statistical results display of the labor service system. The information entry includes the entry of construction projects and worker information. The records of workers entering and exiting the gates are stored in the database of the labor se...

Problems solved by technology

[0003] At present, the construction of the construction site labor management system is limited by hardware and network conditions, and the use status is not ideal. Some projects cannot be used normally. The main problems are as follows: 1. High dependence on wired Internet. In the case of unstable wired Internet, Affects the normal upload of labor personnel attendance data to the cloud database

2. There is a high degree of dependence on the wired LAN, and there are few professionals familiar with network management on the construction site, and there are many computers, so IP address changes and conflicts often occur, resulting in the inability to connect the gate equipment and the industrial computer network, which affects the attendance data in the LAN. normal transmission

3. High hardware compatibility requirements for industrial control external equipment

4. The labor service system needs to be turned on 24 hours a day, but the construction site environment is unstable, and there are often temporary power outages

5. There are generally no full-time labor system management personnel on the construction site, and workers generally have low education levels, high mobility, and unskilled labor software operations

Some laborers use the industrial computer to do irrelevant operations, such as watching videos, playing games, etc., which may cause the industrial computer to be infected with viruses and cause the labor system to fail to work normally.
