Problems solved by technology

[0004] There are many measuring points for tunnel environmental monitoring, and there is a certain distance between the monitoring points. The GPRS communication mode is based on the built-in SIM card for data transmission. Many tunnels are located in remote areas, and the signal of the operator's base station is relatively poor. Unstable quality

Abstract

The invention discloses a multi-type multi-channel data acquisition and transmission device and method, and belongs to the field of data acquisition. The system integrates the vibrating wire signal, the analog signal and the switching value signal, can effectively improve the signal acquisition efficiency, and is high in universality, flexibility and reliability. The Lora module introduced by the invention effectively solves the influence on data transmission caused by weaker signals of a base station of an operator in the tunnel, and the selected combination of the Lora and GPRS communication modules can realize data transmission in a longer distance. Meanwhile, the GPRS DTU is adopted as a main device for data communication, loss is generated only when a GPRS module processes data in the communication process, interference and loss received in the whole communication process are small, normal operation of the communication process can be guaranteed as long as the equipment operates in a place with an operator base station network, and the communication efficiency is greatly improved. Therefore, the transmission rate and the reliability of data transmission can be guaranteed.

Description

technical field [0001] The invention belongs to the field of data acquisition, in particular to a multi-type multi-channel data acquisition and transmission device and method. Background technique [0002] During the construction of a new tunnel, due to the complex and variable geological conditions and the diversity of rock and soil properties, it is inevitable that the tunnel will suffer from structural deformation, cracking, and block loss. Project progress and construction safety. The traditional monitoring and measurement method requires monitoring personnel to enter the construction site, use traditional measurement and display tools to perform manual measurement, process the data after the measurement is completed, and then feed back the measurement results to the relevant engineering departments. In order to improve the problems existing in the traditional tunnel monitoring and measurement and reduce the amount of manpower, it is necessary to improve the following a...
