Real-time construction monitoring and management system without GPS (Global Positioning System) signal

Abstract

The invention provides a construction real-time monitoring management system without a GPS signal. The system comprises a wireless coordinate, a terminal and construction equipment. The number of the wireless coordinates is multiple, the multiple wireless coordinates are arranged in a construction site in an array mode, WiFi chips are arranged in the wireless coordinates and used for sending wireless WiFi signals, and the distance between the wireless coordinates is smaller than the signal coverage range; the terminal is a mobile phone or a tablet computer, the terminal calculates the coordinates of the terminal according to the signal intensity of the wireless coordinates, and the terminal is connected with the server through the wireless base station; the terminal is bound with the construction equipment, the construction equipment is provided with a main control device, the main control device is electrically connected with the terminal, and the terminal sends data to the server. According to the method, coordinate positioning is realized by using a broadcast WIFI signal and a mobile phone as a terminal, the positioning precision can reach cm level, the hardware cost of coordinate positioning is greatly reduced, GPS positioning signals do not need to be collected completely, and the method is very suitable for intelligent management of construction equipment on a construction site.

Description

technical field [0001] The invention relates to the field of construction management of water conservancy and hydropower projects, in particular to a real-time monitoring and management system for construction without GPS signals. Background technique [0002] In the construction process of large-scale hydropower and hydropower projects, a large number of construction equipment are involved. In order to improve the quality of the project, it is proposed to use the database to manage the construction process of the project in the prior art. , highlighting that the construction parameters of the construction equipment are sent to the remote database server for analysis and management in real time through the GPRS network, so as to improve the construction management level and then improve the construction quality. In the management process, it is necessary to use GPS information to locate the coordinates of construction equipment. The existing problem is that the positioning a...
