[0028] See attached figure 1 , a brief description of the detection steps as follows:
[0029] Step 1. Automatic preparation of testing procedures: input test parameters (including rated measurement values, preloading times, selection of specific measurement points, loading and unloading speed, arrival measurement Point stability and waiting for measurement data acquisition time, cycle control, etc.), the system automatically compiles the detection program according to the test parameters;
[0030] Step 2. Sample preloading program: After the test starts, the servo booster\pressurization system preloads the test sample with a set number of cycles;
[0031] Step 3. Sample testing procedure: The servo booster\pressurization system performs automatic force value (pressure) control according to the set measurement point of the entry and return stroke and the loading and unloading speed. After reaching the set measurement point and stabilizing, the data acquisition control system ...

Abstract
The invention discloses a full-automatic geotechnical instrument mechanical performance detection method. The method comprises the following steps: 1, a detection program is automatically programmed, that is, test parameters are inputted according to the name, the specification and the corresponding detection method standard of a detected geotechnical instrument, and a system automatically performs programming of the detection program according to the test parameters; 2, a preloading program is carried out on a sample, that is, after detection is started, a servo forcing (pressing) system performs preloading of preset times on a detection sample; 3, a sample detection program is carried out, that is, the servo forcing (pressing) system performs automatic force (pressure) control according to a set forward and backward measurement point and a loading and unloading speed, after the set measurement point arrives and is stabilized, a data acquisition and control system is used for perform automatic acquisition on needed detection data, and the former sample detection program is repeated according to the circular measurement times set by the program; and 4, after detection is completed, acquired data are calculated and judged, and a detection original record is generated and stored. The method has the advantages that response is quick and accurate; the measurement point is approached unilaterally; and the stabilization time is short.
Description
technical field [0001] The invention relates to the technical field of measurement product quality detection, in particular to a fully automatic detection method for the mechanical properties of geotechnical engineering instruments. Background technique [0002] At present, the general mechanical performance testing equipment for geotechnical engineering instruments in China is a combination of mechanical material testing machine, manual pressure calibration pump and frequency (resistance) reading device, etc. It requires multiple people to control each testing equipment separately to complete the performance testing of the corresponding instrument Work. The disadvantages of this method are that the detection workload is large, the efficiency is low, and the influence of human factors is relatively large. [0003] In recent years, with the increasing maturity and popularization of servo control technology, some testing institutions have begun to replace mechanical material ...
