Bridge health monitoring system provided with power supply fault message prompting function

Abstract

The invention discloses a bridge health monitoring system provided with a power supply fault message prompting function. The bridge health monitoring system provided with the power supply fault prompting function comprises a power supply unit, a power supply fault detecting unit, a sensor group, a microprocessor module and a message receiving and sending module, wherein the power supply fault detecting unit is connected with the power supply unit, the microprocessor is connected with the power supply fault detecting unit and the sensor group and is used for analyzing and handling bridge health conditions and power supply conditions, and the message receiving and sending module is connected with the microprocessor module. The input end of the microprocessor module is connected with a signal conditioning circuit module. The power supply comprises an alternating current direct current circuit converting module, an UPS power source and a power automatic converting module. The sensor group comprises a stress sensor, a deflection sensor, an included angle sensor and an air speed sensor. The bridge health monitoring system provided with the power supply fault prompting function can monitor power supply fault in a real time mode and informs relative workers through the message when faults appear. The bridge health monitoring system provided with the power supply fault prompting function is reasonable in design, complete in functions, high in intelligentized degree and wide in popularization and application.

Description

technical field [0001] The invention relates to the technical field of bridge health monitoring, in particular to a bridge health monitoring system with a short message prompt function for power supply failure. Background technique [0002] At present, due to the scattered areas of bridge construction across the country, most of which are located in remote areas, and most of the bridge sites are high-altitude operations, the instant notification of power supply failures in the bridge health monitoring system has become a major problem in the monitoring industry. [0003] The overall health monitoring of the bridge's own environment is the need for bridge operation safety that is increasingly valued. The health of the bridge's own parameter data can help the national bridge management agency to make important decisions in a timely manner on the safety and hidden dangers of the bridge. However, how to effectively ensure the normal and stable power supply of various instrument...

Problems solved by technology

However, how to effectively ensure the normal and stable power supply of various instruments on the bridge has become an urgent problem to be solved. Traditional bridge health monitoring systems use manual recording and processing of power supply stability, or use wired optical cables to establish connections. Data accuracy is not good

Moreover, there is often a certain time delay in the online transmission of data, and many of them need to use a pair of photoelectric isolation long-line drivers to connect with the front control machine with a long communication cable to transmit the data back to the control and analysis terminal in the room. It is impossible to realize timely monitoring and fault warning of the power supply status of bridge monitoring instruments, and it cannot be sent to the management terminal users in real time
