Problems solved by technology

[0004] At present, regular manual inspection is a common method to obtain the health status of bridge bearings. However, since bridge bearings are generally located in harsh and hidden engineering environments, the limitations of manual inspection methods lead to many diseases that cannot be discovered and treated in time.

Abstract

The invention discloses a self-energy-harvesting friction power generation bridge support health monitoring system and a support adjusting method. The system comprises a friction generator of which the first electrode and the second electrode are respectively arranged on a support upper steel plate and a support; a power amplifier, wherein the input end of the power amplifier is connected with the output end of the friction generator; a vibration exciter, wherein the input end of the vibration exciter is connected with the output end of the power amplifier; an energy collection device which is arranged on the vibration exciter; an energy collection circuit, wherein the input end of the energy collection circuit is connected with the output end of the energy collection device; a wireless acquisition and transmission unit which is connected with the energy collection circuit; a receiving terminal which is used for receiving the current signal information transmitted by the wireless acquisition and transmission unit; and a monitoring cloud platform which is connected with the receiving terminal, wherein the receiving terminal sends the received information to the monitoring cloud platform. The system provided by the invention can be used as a field bridge structure health monitoring system. By the adoption of the support adjusting method, reverse adjustment of the intelligent support can be achieved for support deviation and other diseases with small deviation.

Description

technical field [0001] The invention relates to the field of bridge monitoring systems. More specifically, the present invention relates to a self-capturing energy friction generation bridge support health monitoring system and a method for adjusting the support. Background technique [0002] The bridge support is an important component between the upper and lower structures of the bridge to transfer loads, coordinate structural deformation, and ensure structural safety. Its damage or destruction will directly cause the stress deviation or imbalance of the upper and lower structures of the bridge, which in turn will cause other components. Damage and destruction will accelerate the attenuation of bridge life and directly threaten the overall safety of bridge structures. With the development of economy and the increase of traffic volume, the damage or destruction of bridge bearings has become one of the main diseases of bridges in active service in our country.
