Description of drawings
Fig. 1 is the schematic block diagram of the horizontal self-checking device of balance of the present utility model.
Embodiment
The applied balance of horizontal self-checking device of the present utility model comprises 3 base angle screws, and 1 base angle screw is fixed screw, and another 2 base angle screws are electronic adjustable screw.
As shown in Figure 1, the horizontal self-checking device of balance of the present utility model comprises:
CPU, obliquity sensor, electric pressure converter, analog to digital converter, touch display screen, motor regulating circuit and motor, wherein said electric pressure converter is connected respectively to CPU and inclination angle converter, described inclination angle converter is connected to analog to digital converter, this analog to digital converter is connected to CPU, this CPU is also connected to touch display screen and motor regulating circuit, this motor regulating circuit is connected to motor, and the output terminal of this motor is connected respectively to described two electronic adjustable screw by connecting link or connecting line.
Described electric pressure converter is used for converting supply voltage to CPU and the applicable operating voltage of analog to digital converter.
Described 2 electronic adjustable screw respectively are equipped with an obliquity sensor respectively with on the line direction of described fixed screw.
Described analog to digital converter will become digital signal from the analog signal conversion of obliquity sensor, and export to CPU.
Described CPU processes the digital signal that receives, and will export to touch display screen for the digital signal that shows the inclination angle value, will export to the motor regulating circuit be used to the control signal of regulating described electronic adjustable screw.
Described motor regulating circuit is used for regulating the control signal of described electronic adjustable screw according to being used for of receiving, and exports corresponding magnitude of voltage to motor.
Motor is used for carrying out work according to the voltage of input.The duration that described duty comprises forward, counter-rotating, high-speed rotation, slowly runs and rotates etc.This is well known to a person skilled in the art.Driving described electronic adjustable screw by connecting link or connecting line during described motor operation screws in or screws out.
The specific works process is as follows:
Described obliquity sensor is measured the inclination angle value, with its with the formal output of simulating signal to analog to digital converter, this analog to digital converter will receive analog signal conversion and become digital signal, then export to CPU, this CPU processes the digital signal that receives, at first be formed for showing the digital signal of inclination angle value and export to touch display screen, showing obliquity information by this touch display screen.
If measured balance is not level, so on the line direction of two electronic adjustable screw and fixed screw, if the inclination angle value that the position of electronic adjustable screw higher than fixed screw, shows on touch display screen on the occasion of; Otherwise, if the inclination angle value that the position of electronic adjustable screw lower than fixed screw, shows on touch display screen is negative value.
Then, described CPU also is formed for regulating the control signal of described electronic adjustable screw and exports to the motor regulating circuit according to the instruction of input.This motor regulating circuit is according to the described control signal that receives, export corresponding magnitude of voltage to motor, this motor carries out work according to the voltage of input, driving described electronic adjustable screw by connecting link or connecting line screws in or screws out, until the inclination angle value that shows on touch display screen is zero, balance is transferred to horizontality, this moment, described CPU stopped sending described control information, described motor regulating circuit also stops output services voltage, described motor quits work, and completes thus the process to the Level tune of balance.
Can realize inputting instruction by touch display screen, start functions such as regulating described electronic adjustable screw.
The horizontal self-checking device of balance of the present utility model is simple in structure, easily operation, and adjustment process is convenient, and is quick, is very suitable for the Level tune of balance base.
