Description
Technical field
The utility model is related to sensor technology application, is specifically related to a kind of accelerometer detection of balance detection
Device.
Background technology
With the development of society, economic leap, various electronic consumer products and electric mechanical class control product
Product are full of in life, production and industrial circle.Such as the bucket balance detection of washing machine, the balance detection of elevator each neck
Domain.But it is not high to there is precision in traditional detection, insufficient sensitivity, or even not intelligent enough.Simultaneously these defect drawbacks cause to produce
The use of product is limited by certain environment.
Traditional balance detecting device detection dynamic range is little, and not only sensitivity is low, missing inspection false retrieval.And traditional balance
Detection means is big, bad installation；Simple structure, it is fragile.Such as traditional spring balancing detection means, a kind of conventional method is
Spring is collided, if device is uneven, spring has been touched, spring is flicked, represent that now apparatus system is not in
Poised state.Conventional balanced detection means is high to installation site requirement, and such as conventional balanced detection is mounted on some face, then only
The imbalance in this plane can be detected, the imbalance of other planes will test leakage.
The content of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art is present, there is provided a kind of comprehensive, high accuracy,
Highly sensitive balance detecting device.
The purpose of this utility model is realized using following technical schemes：
A kind of accelerometer balance detecting device, it is characterised in that：The detection means includes three axis accelerometer and micro-
Controller, the SDA (serial data line) of the three axis accelerometer and SDA (serial data line) connections of microcontroller, three axle
The SCL of accelerometer（Serial time clock line）With the SCL of microcontroller（Serial time clock line）Connection, the three axis accelerometer is micro- with this
The VDD of controller（Analog power end）And the VDDIO of the accelerometer（Digital power end）It is connected respectively to 3.3V direct currents
Source.
The accelerometer balance detecting device that the utility model is provided, being arranged on needs the equipment or product of detection balance
On, detection is balanced to corresponding equipment or product using three axis accelerometer, three axis accelerometer is read by microcontroller
Three number of axle evidences, carry out operational analysis and go out current device by the X-axis to accelerometer, Y-axis, the data variation value of the axle of Z axis three
Or product is in balance or non-equilibrium state, so as to realize comprehensive, high accuracy, high-sensitive detection poised state.
The utility model adopts I2C (Inter-Integrated Circuit bus) communication modes, to obtain higher data rate.To add
Speedometer and MCU (microcontroller) are used as detection platform, SDA (serial data line) and SCL（Serial time clock line）Respectively I2C
The data wire and clock line of (Inter-Integrated Circuit bus) bus, the SDA (serial data line) of accelerometer and SCL（During serial
Clock line）Respectively with the SDA (serial data line) and SCL of MCU (microcontroller)（Serial time clock line）Connection.MCU（Microcontroller）
By reading the Data Detection of the axle of accelerometer three to the current poised state of tested measurement equipment or product.MCU (microcontroller)
Initial configuration, such as pattern are carried out to three axis accelerometer by I2C (Inter-Integrated Circuit bus) buses（Standby mode change to
Mode of operation）Configuration, read 3-axis acceleration value, by calculate, draw the degree of balance, if amplitude change very greatly, then it represents that
Imbalance, if changed in a default scope, system is in a poised state.It is with the application on washing machine
Example, in the laundry machine dehydration stage, if washing machine is uneven, occurs tub-impact phenomenon；If balance, laundry machine dehydration
When motor be Running at a constant speed.So it is how to distinguish balance and imbalance from three axis accelerometer, is exactly by three
Distinguish in the amplitude change of axle and speedometer, amplitude changing value exceedes the value under poised state（This value is exactly above say pre-
If value）, it is exactly uneven.
The utility model device can be used in the detecting system of all balances, be three number of axle evidences by computing accelerometer
Change amplitude size to judge a kind of brand-new balance detection solution of current system conditions.With Detection accuracy it is high,
Detect that sensitive, detection range is wide（The different angles of whole sphere high-resolution can be detected）The characteristics of Deng projecting.

Fig. 1 is the utility model example structure theory diagram.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to specific embodiment of the present utility model：
The accelerometer balance detecting device structure that the present embodiment is provided is as shown in figure 1, the detection means includes three axles
Accelerometer DA213 and microcontroller STM8S003, the SDA (serial data line) of the three axis accelerometer and microcontroller
SDA (serial data line) connects, the SCL of the three axis accelerometer（Serial time clock line）With the SCL of microcontroller（Serial clock
Line）The VDD of connection, the three axis accelerometer and the microcontroller（Analog power end）And the VDDIO of the accelerometer（Numeral
Power end）It is connected respectively to 3.3V dc sources.
The present embodiment detection means, based on the axle data variation of accelerometer three, carry out operational analysis go out current device or
Product is in balance or non-equilibrium state.The present embodiment device is arranged on the equipment or product for needing detection balance, is such as pacified
The position of convenient detection balance on washing machine is mounted in, washing machine control panel passes through connection 3.3V power supplys and ground, to this detection means
It is powered, while SDA (serial data line) and SCL of the washing machine control panel by this device of connection（Serial time clock line）It is visiting
The data of this device are asked, then the data by collecting are calculated, draw current laundry machine whether in poised state.
