Problems solved by technology
[0003] The common weighing tester on the market is generally matched with a fixed sensor. Although the test accuracy is guaranteed, the sensitivity cannot be adjusted and the intelligence is not high.
In addition, if the combination test method of "acquisition device + sensor + host computer" is adopted, it lacks integration and is inconvenient to use

Embodiment Construction
[0055] The present invention is introduced below in conjunction with accompanying drawing and example:
[0056] Such as figure 1 As shown, the present invention provides a portable intelligent weighing tester based on an embedded single-chip microcomputer, including a power control unit, a microcontroller unit, a signal conditioning acquisition unit, a human-computer interaction unit, and a data storage unit.
[0057] The power control unit provides power for the external sensing unit, internal microcontroller unit, signal conditioning and acquisition unit, human-computer interaction unit, and data storage unit. The sensing unit is connected to the signal conditioning and acquisition unit through an interface cable, and the signal conditioning and acquisition The unit, the human-computer interaction unit, and the data storage unit are connected to the microcontroller through the I / O port;
[0058] The power circuit in the power control unit converts the mains AC 220V into two...

The present invention provides an intelligent weighing tester and an application method thereof, belonging to the technical field of automatic detection. The invention particularly relates to the intelligent weighing tester capable of carrying out weighing and centroid testing of test pieces of various weight levels of aircrafts, ships, trains, automobiles and the like. A concept of integration and universalization is employed, based on the embedded technology, a measured object can be directly weighed, and functions of measurement parameter adjustment, data acquisition, conditioning and storage, human-computer interaction, one-key extraction, overload and abnormal alarm, error intelligent compensation and the like are realized. Problems of a narrow measuring range, inconvenient portability and low testing efficiency of most existing weighing testers can be solved.
Description
technical field [0001] The invention relates to an intelligent weighing tester and its use method, belonging to the technical field of automatic detection, in particular to an intelligent tester capable of weighing and testing the center of mass of test pieces of various weight levels such as airplanes, ships, trains, and automobiles instrument. Background technique [0002] There are generally two ways to weigh or measure the center of mass of a large test piece such as a vehicle: the suspension method and the pressure bearing method. The suspension method needs to install the force sensor between the crane and the vehicle to be tested, and then use the crane to lift the vehicle, and the weight of the object to be tested can be calculated by measuring the tension on the tension sensor. The disadvantage of this method is that when the object to be measured is too large, the safety is reduced, and the center of mass cannot be calculated by a single sensor, and for large vehi...
