Static load detection device capable of automatically identifying displacement sensor and identification method

Abstract

The invention provides a static load detection device capable of automatically identifying a displacement sensor and an identification method. A displacement sensor identification and acquisition module is arranged; the type of the accessed sensor is automatically identified and judged according to a preset sensor identification scheme; the identified sensor type parameters and sensor serial number information are sent to an embedded computer, and the embedded computer judges the sensor type by electrifying and pre-reading data so as to achieve the purposes of no need of manually selecting thesensor type and automatic identification; by arranging the wireless transmission module, for the inductive displacement sensor, calibration table parameters of the displacement sensor can be automatically obtained from a manufacturer server and automatically matched with channels and numbers of accessed sensors, manual calibration table matching is not needed, and the static load detection deviceautomatically updates a calibration table and carries out automatic matching.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering detection, in particular to a static load detection device and an identification method for automatically identifying displacement sensors. Background technique [0002] As a form of building foundation structure, pile foundation is buried underground and belongs to concealed engineering. Accurately determining the quality of the pile foundation project is very important to ensure the overall quality and safety of the building. According to the "Technical Specifications for Building Pile Foundation Inspection JGJ106-2014", the main methods of pile foundation inspection include static load test, core drilling method, low strain method, High strain method, acoustic transmission method, etc. Among them, the static load test usually uses a static load tester, which consists of the following parts: static load detection host, displacement sensor, oil pressure sensor, acquisition base s...

AI Technical Summary

Problems solved by technology

If the inductive frequency modulation displacement sensor is used on site, it is necessary to select the frequency regulation table corresponding to the frequency modulation displacement sensor connected to each channel, and it must correspond one by one. If the selected frequency regulation table does not correspond to the frequency modulation displacement sensor, in this way In the process, there will be a large error in the actual displacement value, which will affect the quality and efficiency of detection.

Therefore, in the current method, before the sensor is installed and connected, it is necessary to manually record the number of the sensor connected to each channel. If it is not recorded in advance, it is randomly connected, and it is necessary to manually go to the bottom of the stack to check the number and channel. Register, there is a great security risk going back and forth like this

In addition, before leaving the factory, the static load detectors of each manufacturer need to manually enter the calibration tables corresponding to the serial numbers of the standard inductive displacement sensors into the static load host for the convenience of calling when the user performs sensor matching. Time-consuming and labor-intensive, and there is a risk of input errors. In addition, if the user needs to replace or purchase a new displacement sensor, it usually needs to be sent back to the manufacturer for input or directly sent to the user to add the rate table. The user experience is poor and it will also affect the construction period.

To sum up, at present, the operation and calibration mode of the static load detectors of various manufacturers have put forward relatively high requirements for the detector personnel, and are prone to errors, and there are potential safety hazards at the same time.
