Problems solved by technology

The centralized system structure faces problems such as difficult wiring and excessive wiring length, so it is difficult to implement effectively in super high-rise buildings
If a distributed system structure is adopted, it faces the problem of low synchronization
At present, the continuous vibration monitoring of super high-rise buildings is not fully carried out, which makes effective continuous vibration monitoring methods even more lacking.

Embodiment 1

[0056] see figure 1 , the present embodiment discloses a distributed continuous vibration monitoring system 1000, the monitoring system includes a plurality of subsystems 0100 separately arranged at each measurement point of a super high-rise building. The subsystem 0100 includes a terminal 0110, an acquisition unit 0120, and a receiving end 0130. Each subsystem 0100 is independently set up and does not need to be connected with each other through cables to independently collect vibration data at the measurement points.

[0057] The terminal 0110 includes a memory 0111 and a processor 0112, configured to issue control instructions according to a preset sampling frequency and a preset sampling duration. It can be understood that the preset sampling frequency and the preset sampling duration are preset by the user according to the structural characteristics of the monitored super high-rise buildings. Exemplarily, within the preset sampling time period, the processor 0112 sends ...

Embodiment 2

[0072] On the basis of Embodiment 1, this embodiment further discloses a computer program, which is stored in the memory 0111 of the terminal 0110, and is used for execution by the processor 0112 to realize the vibration data of each subsystem 0100 during the continuous monitoring process. The synchronization between them ensures the monitoring accuracy.

[0073] see figure 2 , Exemplarily, the computer program includes the following steps:

[0074] A: Eliminate the clock error and the program time difference according to the satellite second pulse signal. It can be understood that both the clock error and the program time difference affect the vibration data collected by the sensor 0122 . Therefore, by compensating the vibration data collected by the sensor 0122 according to the second pulse signal of the satellite, the clock error and the program time difference can be eliminated at the same time.

[0075] B: Eliminate the packet loss time difference according to the sat...

Abstract

The invention discloses a distributed vibration continuous monitoring system, comprising a plurality of subsystems which are separately set at each measurement point of a super high rise building. Thesubsystems comprise terminals which comprise memories and processors and are used for sending control instructions according to preset sampling frequency and preset sampling duration; collection units which are separately set at each measurement point of the super high rise building and are used for collecting vibration data of the corresponding measurement points according to the control instructions and outputting the vibration data to the terminals; and receiving ends which are used for receiving satellite second pulse signals to obtain satellite standard time. Computer programs are storedin the memories. The processors perform the computer programs, thereby eliminating system time errors in the vibration data received by the terminals. The distributed vibration continuous monitoringsystem provided by the invention has a distributed structure easy to realize and excellent data collection synchronism. Vibration continuous monitoring of the super high rise building is satisfied.

Description

technical field [0001] The invention belongs to the technical field of vibration monitoring, in particular to a distributed continuous vibration monitoring system. Background technique [0002] With the process of urbanization, my country's construction industry has ushered in an opportunity for rapid development. All kinds of buildings have sprung up like mushrooms after rain, meeting the needs of people's life, production and business communication, making urban civilization unprecedentedly prosperous. In order to ensure the structural safety of buildings and provide design references for the construction industry, extensive and long-term continuous monitoring of buildings is required. [0003] Among them, the vibration frequency of the building has an important influence on the structural performance of the building, and is an important monitoring index. Vibration monitoring is the monitoring work carried out for vibration frequency, and the collection of vibration data...
