Technical Field
The invention relates to the field of parameter setting, in particular to a parameter data real-time setting system and method.
Background
A parameter, also called a parameter variable, is a variable. One is concerned with the variation of, and interrelationship between, several variables, one or some of which is called an independent variable and another one or other of which is called a dependent variable, when studying the current problem. If one introduces one or several additional variables describing the change of the independent variable and the dependent variable, the introduced variables are not necessarily the ones that the current problem has to study, and such variables are called parameter or parameter.
Parameters are an option available for many machine settings or repairs, literally understood to be data that may be referenced, but sometimes not all. It may be an assigned constant value for a given application; when broadly referred to, it can be a variable that controls other quantities that vary as a function of its variation. In brief, the parameters are referenced by humans.
In mathematics, the parameter thought is carried through in analytic geometry. For geometric variables, one expresses the variable by an algebraic expression comprising letters called a parametric expression, where the letters are called parameters. The geometric properties and algebraic relations of the graph are used to connect the integral form to solve the problem. Meanwhile, the 'parameter method' is a source of a lot of problem solving skills.

Detailed Description
Embodiments of the ventilation parameter data real-time setting system and method of the present invention will be described in detail below.

The working principle of the direct current generator is that the alternating electromotive force induced in the armature coil is changed into direct current electromotive force when being led out from the brush end by the cooperation of the commutator and the brush. The direction of the induced electromotive force is determined according to the right-hand rule, namely the magnetic induction line points to the palm of the hand, the thumb points to the moving direction of the conductor, and the other four fingers point to the direction of the induced electromotive force in the conductor.
The electromagnetic dc motor is composed of stator magnetic pole, rotor (armature), commutator (commonly called commutator), brush, casing and bearing. The stator magnetic pole (main magnetic pole) of the electromagnetic dc motor is composed of an iron core and an excitation winding. The motors can be classified into series-excited dc motors, parallel-excited dc motors, separately-excited dc motors, and compound-excited dc motors according to their excitation (old standard called excitation). The law of stator pole flux (generated by energizing the field coil of the stator pole) is different due to different excitation modes.
