Technical field
The utility model belongs to the dynamometer field, is specifically related to a kind of self diagnosis dynamometer.
Background technology
At present, the product structure of the force measurement instruments such as the digital display type pull and push dynamometer of existing domestic and imported, torsion tester, power dynamometer generally all comprises sensor, for gathering induced signal; D/A conversion unit, be connected on sensor, for the induced signal that sensor is received, carries out sending into the central data processing unit after digital conversion; The central data processing unit, be connected to described digital to analog converter, and the digital signal from digital to analog converter is processed.But current dynamometer is after use, the client generally can't judge that whether the test result of dynamometer is accurate voluntarily.Detect if need, need the professional to adopt professional equipment to detect, take time and effort.
The utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of self diagnosis dynamometer; Whether this self diagnosis dynamometer can accurately carry out self diagnosis to the test result of dynamometer.
The utility model is achieved by the following technical solution:
A kind of self diagnosis dynamometer comprises:
Sensor, for gathering induced signal;
D/A conversion unit, be connected on sensor, for the induced signal that sensor is received, carries out sending into the central data processing unit after digital conversion;
The central data processing unit, be connected to described digital to analog converter, and the digital signal from digital to analog converter is processed;
Output unit, be connected to described central data processing unit, for exporting the measurement result of dynamometer;
It is characterized in that, in described central data processing unit, be provided with the deflection storer, described deflection storer is for being stored in the maximum deformation quantity of dynamometer range ability inner sensor.
Further, described central data processing unit comprises single-chip microcomputer and peripheral circuit thereof, and described deflection storer consists of the internal storage of single-chip microcomputer.
Further, described self diagnosis dynamometer also comprises input block and display unit, and described input block is for inputting data or steering order to the central data processing unit; Described display unit is for showing the measurement result of output unit output.
Self diagnosis dynamometer described in the utility model, by the deflection storer is set in the central data processing unit, stores the maximum deformation quantity at dynamometer range ability inner sensor in the deflection storer.The maximum deformation quantity of described sensor is after dynamometer is dispatched from the factory calibration, by gear train, test platform is carried out the sensor self-deformation amount obtained after standard volume (maximum range) precompressed.After dynamometer uses a period of time, the client can carry out by gear train the displacement precompressed equated with maximum deformation quantity to test platform, the output valve of dynamometer and former standard volume of dispatching from the factory are compared, and then detect current dynamometer whether also in effective usable range, reach the function of sensor being diagnosed voluntarily with the particular displacement variable quantity, this self diagnosis dynamometer can greatly facilitate the user.
The accompanying drawing explanation
The structured flowchart that Fig. 1 is self diagnosis dynamometer described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the utility model provides a kind of self diagnosis dynamometer, comprising: sensor, for gathering induced signal; D/A conversion unit, be connected on sensor, for the induced signal that sensor is received, carries out sending into the central data processing unit after digital conversion; The central data processing unit, be connected to described digital to analog converter, and the digital signal from digital to analog converter is processed; Output unit, be connected to described central data processing unit, for exporting the measurement result of dynamometer; It is characterized in that, in described central data processing unit, be provided with the deflection storer, described deflection storer is for being stored in the maximum deformation quantity of dynamometer range ability inner sensor.
The processing unit of central data described in the present embodiment can realize by single-chip microcomputer and peripheral circuit thereof, and described deflection storer consists of the internal storage of single-chip microcomputer.
