Problems solved by technology

[0007] Therefore, the vibration of the building will cause discomfort to the human body
At present, house vibration detection products usually need to use external acceleration sensors to complete the test. The test process and the post-processing of test data require certain professional basic knowledge. Therefore, comfort evaluation based on external sensors is difficult to popularize and apply in daily life.

specific Embodiment approach 2

[0086] Specific embodiment two: the system includes a smart phone 1, a mobile phone client application software 2 and a mobile phone support 3 and consists of three parts. The mobile phone support 3 is a suction cup mobile phone holder, which ensures the stable connection between the smartphone 1 and the mobile phone support 3 and between the mobile phone support 3 and the structure under test, and realizes a rigid connection between the smartphone 1 and the structure under test, ensuring smart The boundary conditions between the mobile phone 1 and the structure under test are ideal, so as to realize fine monitoring. Smartphone 1 has a built-in acceleration sensor 1-1 and gyroscope 1-2, which can test the acceleration information in the environment inertial coordinate system. The analysis module performs post-processing on the signals measured by the acceleration sensor 1-1 and gyroscope 1-2 to obtain Acceleration peak, through Fourier transform and power spectral density anal...

specific Embodiment approach 3

[0093] The system is composed of smart phone 1 and mobile client application software 2. In this example, when testing the structural comfort, the smart phone 1 can be placed directly on the floor of the structure under test. The accuracy of the test data is slightly lower than in Example 1, and other steps are the same as in Example 1.

[0094] The test system is based on a smart phone mobile terminal, does not require other external equipment, and has no network requirements. It can obtain real-time vibration and torsion information of the house, and provides a portable, easy-to-operate, and low-cost feasible solution for the house comfort test. The test system can be widely used in the comfort test of ordinary residences, office buildings, hotels, villas and public buildings, and provides a solution for the comfort evaluation of building structures in the process of real estate purchase, lease and use.

Abstract

The invention discloses a building structure comfort degree testing system based on a smart phone, and relates to the technical field of building vibration detecting and evaluating. The system comprises a smart phone, phone client application software and a phone stent, wherein the smart phone is internally provided with an acceleration sensor and a gyroscope, the acceleration sensor is used for measuring vibration data of a building structure, the gyroscope is used for measuring e moving direction of a relative inertial coordinate system of the smart phone, and the phone client software comprises a control module, a collecting module, an analyzing module, a display module and a storage module. The system has the advantages that functions of the testing and real-time displaying of acceleration data are supported, the application scenarios of testing and current regulated threshold values are combined, and information of two aspects of structural vibration acceleration peak value and frequency is combined to comprehensively judge the comfort levels of a building structure and environment.

Description

Technical field: [0001] The invention relates to the technical field of building vibration detection and evaluation, in particular to a smart phone-based building structure comfort testing system. Background technique: [0002] The broad concept of comfort refers to the comfortable degree of the human body in the environment. There are many factors that affect the comfort of the human living environment, such as indoor temperature, humidity, noise and lighting. [0003] With the rapid development of my country's infrastructure, the operating mileage of high-speed railways has reached 25,000 kilometers, accounting for two-thirds of the world. In addition, it is estimated that by 2020, the operating mileage of urban rail transit will reach more than 73 million kilometers. However, With the increase of rail traffic speed, line density and traffic density, the vibration pollution of rail traffic to the environment is aggravated, especially the vibration impact on houses, which s...
