Abstract

The invention discloses a vehicle-mounted drop weight deflectometer calibration device, and relates to the technical field of vehicle-mounted drop weight deflectometers. The vehicle-mounted drop weight deflectometer calibration device comprises a main body and a calibration system, the front surface of the main body is provided with a door body, and the front surface of the door body is embedded with a touch screen; and the calibration system comprises an MCU controller, an information receiving module, a signal processing module, a feedback module, a control module, a data processing module and a storage module. The control module comprises a first control node, a second control node, a third control node, a fourth control node, a fifth control node and a sixth control node. According to the invention, the calibration area can be converted into a vacuum environment, the influence of air resistance on the calibration process is reduced, the base of the loading system of the vehicle-mounted drop weight deflectometer can be fixed, the influence of shaking on calibration is reduced, and the drop hammer falling data of the loading system of the vehicle-mounted drop weight deflectometer in the vacuum environment can be rapidly detected so that the data can be conveniently compared with theoretical data for calibration and correction.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted drop weight deflectometers, in particular to a calibration device for vehicle-mounted drop weight deflectometers. Background technique [0002] The vehicle-mounted drop weight deflection tester was produced in the early 1970s and is a kind of pulse dynamic deflection tester. It has the advantages of no damage, fast measurement speed, high precision, etc., and it simulates the driving load well, and the test result is the deflection basin data, so it is widely used in the world. Its scope of application is mainly in road maintenance management. [0003] However, during the long-term use of the vehicle-mounted drop weight deflectometer, some errors often occur, especially for the vehicle-mounted drop weight deflectometer, which will cause some energy loss when the drop weight falls, resulting in measurement deviations, which need to be calibrated . Contents of the invention [0004] The...
