Embodiment 1

[0035] see figure 1 , figure 2 , the present invention discloses a bridge remote data collection and analysis system, the system includes a data collection module (also known as a collection terminal), a data monitoring module (also known as a monitoring terminal), a data storage module (also known as a storage terminal), a control module ( Also known as the control terminal). The data acquisition terminals of the bridge monitoring system are distributed in the box girder and tower of the bridge. Its main task is to collect environmental data, static / dynamic response and other signals of the bridge with the cooperation of various sensors in accordance with the requirements of the control terminal, and then transmit these signal data to the monitoring terminal in real time on the one hand; The form is stored locally for download by the data storage terminal and the database is used to manage signal data in a unified manner.

[0036] The data monitoring module is used to mon...

Embodiment 2

[0098] In order to facilitate and standardize the debugging and use of the acquisition terminal software, each acquisition terminal uses a unified software architecture. Since the hardware configuration of each terminal is different, the collected physical signals are also different, so when designing and implementing the data collection terminal software, the following aspects should be fully considered:

[0099] ——Unified software architecture

[0100] On the one hand, the unified software architecture enables the upper computer to interact with the acquisition terminal through a consistent interface for commands, status and data, which is convenient for users; on the other hand, it can greatly improve the code reusability, so that all terminals use the same set of codes (different The terminal is only different in the configuration file information), which is convenient for developers to maintain the code and reduces the probability of errors.

[0101] ——Modular and scalab...

Abstract

The invention discloses a system for acquiring and analyzing remote data of a bridge. The system comprises a data acquisition module, a data monitoring module, a data storage module and a control module, wherein the control module is connected with the data acquisition module, the data monitoring module and the data storage module and used for controlling the operations of the data acquisition module, the data monitoring module and the data storage module. The remote real-time system for acquiring and analyzing the data of the bridge can be accessed to a bridge acquisition and analyzing system. The system is mainly used for improving the level and efficiency of running, maintenance and management of a large bridge engineering structure, and is favorable for ensuring the security of structures and traveling vehicles.

Description

technical field [0001] The invention belongs to the field of intelligent control, and relates to a method for real-time remote data collection and analysis, in particular to a bridge real-time remote data collection and analysis system; meanwhile, it also relates to a collection and analysis method for the remote data collection and analysis system. Background technique [0002] The distributed remote data acquisition and analysis system is composed of centralized operation and management unit, distributed measurement and control unit and communication network. It is developed on the basis of network technology, large-scale integrated circuits and embedded technology. Its main features are: it can decompose complex systems into relatively simple independent modules, and the system hierarchy is clear. The entire system is optimized and decomposed, and the monitoring tasks are allocated reasonably, which effectively improves the operating speed of the system. Data collection i...
