Embodiment Construction
[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0052] The invention relates to a working condition control method and device for engineering machinery, which can be used in known closed-loop control systems. figure 1 Shown is the working principle diagram of the closed-loop control system. The controller sends control information to the execution unit, and the execution unit completes the control of the measurement and control object. After the detection signal of the measurement and control object is collected...

The invention provides an engineering machine and a working condition control method and a working condition control system thereof. The method includes the following steps: the initial data of the engineering machine are acquired; before or after the initial data of the engineering machine are acquired, whether the engineering machine is stable or not is judged; if yes, then precision calculation is carried out according to the acquired data; if not, then the engineering machine executes unstable working conditions; whether the calculated precision meets preset precision or not is judged; if yes, then the engineering machine executes corresponding stable working conditions; if not, then data acquisition is continued, precision is recalculated, and whether the calculated precision meets preset precision or not is rejudged. The invention can execute different working conditions according to the stable state of the engineering machine. The invention has the advantages of controllable precision, stable and controllable system response time, short response time and the like. Moreover, the precision of the invention can be infinitely increased in theory.
Description
technical field [0001] The present invention relates to the fields of measurement and control and engineering machinery, in particular to an engineering machinery and a working condition control method and device thereof. Background technique [0002] With the development of information technology, modern electronic measurement and control systems (especially in the field of construction machinery) have put forward higher requirements for data acquisition, and in some occasions, the signal data detected is required to be more reliable and accurate. However, there are various noises in the measurement and control environment, which affect the accuracy of the signal. In order to remove or reduce the impact of noise in the acquisition system, components with high cost and low noise characteristics and a filtering method with relatively large time delay are often used. [0003] When the components used reach a certain level, to be able to detect weak signals well, the filtering...
