Test and control system based on 32-bit ARM 211B test machine

211B is a testing machine measurement and control system dedicated to the industry by Force Control Instrument Technology Co., Ltd. with 32-bit ARM technology. It adopts the latest technology of this century; it can be used for the tension, compression, bending, Measurement and control of shear, peel, torsion and other tests. The products have been adopted by more than 30 companies in China, Taiwan, and Japan. m211B is a digital display instrument with liquid crystal display. Features: 66MHz 32-bit ARM technology test process voice prompt, the world's only in the industry, photoelectric encoder acquisition, four-quadrant acquisition using technology of the century: the least circuit, complete functions, the most advanced performance, easier debugging. Modular software structure: MS-ACCESS database, using VBS+SQL to calculate parameters Technical indicators: The hardware has 2 analog input channels (expandable to 3) for force measurement and deformation measurement (small deformation electronic extensometer or analog large Deformation, 28 ADC); 3 photoelectric encoder input channels are used for position measurement and digital large deformation measurement; 1 pulse output channel is used for test bench control. The details are as follows: Force measurement: Resolution 1/250000 (500000 subdivision code) Accuracy 0.3% Small deformation (strain rail): Resolution 1/250000 (500000 subdivision code) Accuracy 0.3% Digital large deformation (orthogonal output photoelectric code The resolution is determined by the mechanical system and the photoelectric encoder; generally up to 5um precision 4-quadrant acquisition, the instrument system has no error, and the resolution is increased by 4 times. Displacement (quadrature output photoelectric encoder): The resolution is determined by the mechanical system and photoelectric Encoder decision; generally up to 1um precision 4-quadrant acquisition, the instrument system has no error, and the resolution is increased by 4 times. Acquisition rate: 50 times/S Speed u200bu200bcontrol (for electronic universal testing machine): Control method Pulse frequency range 0.072 Hz ~ 5500 kHz Accuracy 0.1% Hardware parameter adjustment method: Online adjustment by software is suitable for servo controllers with pulse input, stepper motor controllers; an external F/V converter can be used for AC variable frequency controllers. Operation box functions 5 function buttons :Up, down, stop, run, reset, 4 inching buttons for fine adjustment of position, up and down indicator lights on the test bench. Operation panel functions 27 function buttons: up, down, stop, run, clear, result, print, set, -, decimal point, 0-9 number keys, clear, enter, and menu selection keys. Display 240x128 LCD resolution graphic display, 5 inches; display data and curves. Instrument functions 8 functions: stretching, compression, bending, shearing, tearing, peeling, metal stretching, rubber and plastic stretching. The meter prints 32 kinds of reports. Operating system Windows XP / Me / 98/2000 Inspection functions Basic: stretching, compression, bending, shearing, tearing, peeling, expandable: puncture, torsion, bursting, pendulum impact. Program module Main program, configuration file, default value file, parameter calculation program, report file, sound file, database prototype, startup picture. The data storage and processing format is MS ACCESS, which can be viewed and edited by other software (such as Office). Report production method Crystal Report, supports test curves, geometric shapes, pictures (such as logos, stamps, etc.), text color and background color can be set, based on a database, commonly used functions: maximum, minimum, average, automatic sample counting, standard deviation , Summation, etc. Operators: +, -, *, /, and, or, not, if_then_else, etc.; the number of digits after the decimal point can be set, and the reduction method can be set. Data processing language SQL (via object) + VBScript or JavaScript curve processing real-time curve, force value-deformation, force value-time, deformation-time, stress-strain, stress-time, strain-time; the upper and lower yield can be manually selected through the curve Point, elastic segment, starting point of hardening. Partial zoom. Curves can be embedded into other texts (such as Word) as objects. Voice event prompts are available (the only testing machine industry in the world at present). Operation process control, automatic start operation, automatic judgment of cracks, fixed time, fixed force value, fixed deformation, automatic return to operation Starting point. Supporting operation animation demonstration Yes (with voice)
