Description

A kind of anglec of rotation indicating device

Technical field

The utility model belongs to a kind of electronic weighing instrument measuring the level angle displacement of object.

Background technology

Level angle indicating device more common in life is generally physical construction, such as dial register.But, the shortcoming of pointer instruction angle displacement is that the words that moving part and look-out station are not together just need complicated physical construction to realize, to structural limitations larger and can only indicate moment angle displacement amount, and can not observation angle change speed and acceleration.Based on this, applicant is after the major function measured level angle and indicate positions, through design and constantly experimental verification have devised this kind and software and to combine closely the level angle displacement measurement and indicating device that form, this device can be used in the occasion that needs measurement horizontally rotates angle.

Summary of the invention

The purpose of this utility model is to provide a kind of can measurement and the device of convenient observation level angle activity, current angular mobility amount can be indicated to indicate angular mobility speed and the acceleration of moment in a digital manner clearly in pointer mode intuitively simultaneously.

The purpose of this utility model is realized by following scheme:

Utilize an Electron Angular accelerometer module, for the activity taken measurement of an angle, use a single-chip microcomputer and this model calling to read the measurement data of this module, and utilize the angular mobility amount of a LCDs display dynamic transient.

Concrete structure is:

Circuitry is made up of electronic accelerometer module (hereinafter referred to as accelerometer), minimum Single Chip Microcomputer (SCM) system (hereinafter referred to as MCU) and liquid crystal display, accelerometer and MCU transmit angular mobility data by Serial Port Line, and angular mobility amount displaying contents is delivered to liquid crystal display by parallel port data line and exported by MCU.

Accelerometer transmits the data such as horizontal angle displacement, angular velocity, angular acceleration to MCU by two serial port data lines, powered by VCC, GND and to power to accelerometer, GND also provides the ground wire of serial ports; The speed of MCU degree of will speed up meter process is converted into the display data of liquid crystal display after treatment, by the I of MCU O mouth with parallel port data transfer mode, be sent to liquid crystal display, drive liquid crystal display display pointer instruction angle displacement, and angles of display shift value, angle rates are worth and angular acceleration values in a digital manner.

The beneficial effects of the utility model are: for the various equipment needing the level angle displacement measuring object, such as waist mobilizer (a kind of waist movable apparatus for exercising), or an independent formation equipment is in order to indicate the activity of level angle.Arranging of the utility model observation position is relatively more flexible, and liquid crystal display can be placed on any position being easy to observe.In display mode, electronic indicator has the feature of mechanical indicator visual pattern, and numerical monitor has again the accurate feature of clear readability that mechanical indicator does not have.

Embodiment

In order to make those skilled in the art person understand the utility model scheme better, and enable above-mentioned purpose of the present utility model, feature and advantage become apparent more, below in conjunction with embodiment, the utility model is described in further detail.

Accelerometer module adopts high-precision gyroaccelerometer, adopts advanced digital filtering technique, effectively can reduce measurement noises, improves measuring accuracy.Inside modules is integrated with attitude algorithm device, coordinates Dynamic Kalman Filtering algorithm, can under dynamic environment the current pose of accurate output module, attitude measurement accuracy 0.01.Processor reads gyrostatic measurement data and then exports MCU to by serial ports.The Data Collection that gyroscope is sent by serial ports by MCU, in an array, after array is filled with, is resolved data, is isolated the angle displacement of angular mobility, angular velocity and angular acceleration values.Wherein angle displacement is by being converted into the pointer display data of liquid crystal display after calculating, and angular velocity and angular acceleration are then converted into text display data, are directly presented on liquid crystal display in a digital manner.

The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
