Embodiment 1

[0042] Such as figure 1 and 2As shown, this embodiment discloses that the present invention discloses a system for real-time online monitoring of the working status of the anti-seismic support and hanger of the electromechanical pipeline, including the anti-seismic support and hanger 1, the miniature acceleration sensor 2, the signal transmitter 3, the protection box 4 and the monitoring system. Terminal 5, where:

[0043] The anti-seismic support hanger 1 is composed of an anti-seismic support and a bridge frame, one end of which is fixedly connected to the electromechanical pipeline bridge frame, and one end is fixed on the building structure;

[0044] The micro-acceleration sensor 2 is fixed on the anti-seismic support of the anti-seismic hanger 1 to measure the acceleration time history data; the micro-acceleration sensor 2 provided in this embodiment integrates perception-acquisition-transmission, and does not need additional data acquisition Instruments and storage dev...

Embodiment 2

[0055] The present invention also discloses a method for real-time online monitoring of the working state of the anti-seismic support and hanger of the electromechanical pipeline. The system for monitoring the working state of the anti-seismic support and hanger of the electromechanical pipeline in Embodiment 1 is used for monitoring, including the following steps:

[0056] Step 1: Earth pulsations, external abnormal vibrations or earthquake shock waves can trigger the miniature acceleration sensor 2 to work;

[0057] Step 2: The miniature acceleration sensor 2 generates relevant data during motion and transmits it to the signal transmitter 3, and the signal transmitter 3 transmits the acceleration data to the cloud and the monitoring terminal 5;

[0058] Step 3: The data will be processed at the monitoring terminal 5 to display the acceleration time history of the anti-seismic support hanger 1 during the vibration process, perform Fourier transform to obtain the frequency doma...

Abstract

The invention discloses a system and method for monitoring the working state of an anti-seismic support hanger of an electromechanical pipeline online in real time. The system comprises the anti-seismic support hanger, a micro acceleration sensor, a signal transmitter, a protection box and a monitoring terminal. The anti-seismic support hanger is fixed to a building structure; the micro acceleration sensor is fixed on an anti-seismic support of the anti-seismic support hanger and is used for measuring acceleration time-history data; the signal transmitter is arranged in the micro accelerationsensor and is used for transmitting a remote wireless signal to the cloud end for storage; the protection box is a totally-enclosed box cover, covers the micro acceleration sensor and the signal transmitter, and is used for enclosing and protecting the micro acceleration sensor and the signal transmitter; and the monitoring terminal is used for receiving the remote wireless signal and displaying and processing the acceleration data. The monitoring system is simple, efficient, small in size, good in protection performance, capable of achieving real-time remote on-line monitoring, convenient tooperate and capable of achieving multi-platform intercommunication, and rapid evaluation of the structural state and real-time pushing of graded early warning events are achieved.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and electromechanical engineering, in particular to a system and method for real-time on-line monitoring of the working state of anti-seismic supports and hangers of electromechanical pipelines. Background technique [0002] Building mechanical and electrical pipeline facilities are non-structural components. Under the action of an earthquake, the damage of the mechanical and electrical piping equipment system will not only cause direct damage and threat to the safety of human life and property, but also affect the post-earthquake rescue and repair work. Therefore, strengthening The seismic performance of electromechanical pipeline equipment is of great significance. The anti-seismic support and hanger is a system used to fix electromechanical pipeline equipment and has the function of anti-seismic and shock absorption. It can significantly reduce the dynamic response of electromechanic...
