Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, a device for measuring the vertical displacement of a building is composed of a light source 1 (laser or photodiode), an optical lens 2, a glass tube 8, a CCD photoreceptor or a PSD photoelectric device 7, and the like. The light source 1 and the CCD photoreceptor 7 or the PSD photoelectric device are all fixed on the bottom plate of the instrument. The light source 1 is placed at the focal point of the lens, and the field of view of parallel light passing through the lens 2 is large enough to fully cover the entire measurement range and the CCD photoreceptor or PSD photoelectric device 7 . The upper part of the glass tube 8 is equipped with a liquid 5 with low light transmittance; the lower part communicates with a large liquid container (not shown in the figure), and the large liquid container is placed on ...

Abstract

The invention discloses a device and a method for measuring the vertical displacement of buildings, wherein using the principal of connected pipes to realize multipoint communication, the device converts small elevation variation at an equipment installation location into vertical position variation of a liquid level interface by measuring the position of the liquid level interface in a communicating container, and the vertical position variation of the liquid level interface is directly detected by a CCD sensor or a PSD photoelectric device. The functions of the CCD sensor or the PSD photoelectric device such as program control driving, signal processing and identification, data acquisition, communication with computers, etc. are implemented by using a single chip machine. The device integrates sensor and peripheral circuit and is manufactured by specially-designed moulds, thereby achieving good integrity and sealing performance and convenient installation. The device can be used forobserving the vertical deformation of dam, bridge, dock, high slope, ground fissure, fault, weak intercalated layer, etc.

Description

technical field [0001] The invention relates to a measuring device and a measuring method, in particular to a device and a method for measuring the vertical displacement of a building. Background technique [0002] Since there are relatively few measuring devices for vertical displacement of buildings in China at present, and the measurement accuracy is not high enough, accurate measurement of vertical displacement of buildings cannot be realized, which brings great inconvenience to the staff who need to collect vertical displacement of buildings . Contents of the invention [0003] The purpose of the present invention is to provide a connecting pipe technology that uses the earth's gravity plane as a reference plane, a device and a method that can accurately measure the vertical displacement of buildings, and can solve the problems of inaccurate vertical displacement of buildings and low measurement accuracy at present. question. [0004] To achieve the above object, th...
