The intelligent weight balance comprises a data acquisition module, wherein the data acquisition module is connected with a micro controller module through an A/D (analog/digital) conversion interface; the micro controller module is electrically connected with a man-machine interaction module; the micro controller module is connected with a monitoring computer through a ZigBee wireless transmission module; the man-machine interaction module comprises a key module and a display module; the whole system converts weight information of a human body into an electric signal; the electric signal is subjected to AD conversion and is converted into a digital signal; the digital signal is processed by the micro controller module, is displayed by an LCD (liquid crystal display) screen, and is sent to the monitoring computer through the ZigBee wireless transmission module; and the monitoring computer records and analyzes the information of users. The whole system is in a dormant state under the condition of not weighing and is awakened in a timing awaking manner, and the system continues to enter the dormant state if not detecting weight after being awakened, so that the aim of power saving is achieved.

Description

A kind of intelligent scale
Technical field
The utility model relates to wireless communication field, is specifically related to a kind of intelligent scale.
Background technology
Modern society's Along with people's growth in the living standard, people more and more pay close attention to the healthy of oneself, and body weight is to weigh a whether healthy major criterion, therefore the body weight with a stage body restatement periodic measurement oneself is very necessary.Traditional instrumented scale, the error ratio of not only measuring is bigger, and reading is very inconvenient, can take more space on the volume.Therefore a portable, easy to operate, the scale that measuring accuracy is high just is good at satisfying people's demand.Scale on the market much adopts the mode of mechanical vibration to start shooting now; Can cause error owing to the reason of mechanical vibration in the moment of start like this, influence the accuracy of measurement result, and the power consumption of scale also be the problem that the user pays close attention to; Scale in the market can only be weighed to current body weight; Can't carry out record to the body weight of a period of time, can not analyze, have certain defective the human body body weight.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of the utility model is to provide a kind of intelligent scale, this scale through the ZigBee wireless transmission method with the body weight information uploading to computing machine; Computer software is that every user provides and independently lands number of the account and password, not only can well protect user's privacy, and can user's body weight information be write down and analyze; For user's health provides foundation, the ZigBee wireless transport module has low-power consumption, and transmission is stable; Free transmission band is arranged; The advantage that transfer rate is high is fit to short distance, the radio communication requirement of low-power consumption very much.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of intelligent scale; Comprise data acquisition module; Data acquisition module connects micro controller module through the A/D translation interface, and said micro controller module is electrically connected with human-computer interaction module, and said micro controller module connects monitoring computer through the ZigBee wireless transport module.
Described human-computer interaction module comprises key-press module and display module.
Said data acquisition module adopts pressure sensor.
Said microcontroller is selected SN8P1937 for use.
Total system becomes the body weight information of human body into electric signal through pressure transducer, and electric signal is through becoming digital signal after the AD conversion, and digital signal is through the processing of micro controller module; Show through LCD display, and send to monitoring computer through the ZigBee wireless transport module, monitoring computer writes down and analyzes user's information; Under the state of not weighing; Total system is in dormant state, and the mode that adopts timing wake-up does not detect weight with system wake-up if wake the back up; Then continue to get into dormancy, reach purpose of power saving like this.
Description of drawings
Accompanying drawing 1 is the overall schematic of the utility model.
Embodiment
In the face of the structural principle of the utility model, principle of work is described further down.
With reference to accompanying drawing 1; A kind of intelligent scale comprises data acquisition module, and data acquisition module connects micro controller module through the A/D translation interface; Said micro controller module is electrically connected with human-computer interaction module, and said micro controller module connects monitoring computer through the ZigBee wireless transport module.
Described human-computer interaction module comprises key-press module and display module.
Said data acquisition module adopts pressure sensor.
Said microcontroller is selected SN8P1937 for use.
Said pressure transducer inserts microcontroller with the body weight information of gathering through the A/D conversion; Microcontroller shows body weight information after data are handled through the LCD human-computer interaction module; Microcontroller links to each other with the ZigBee wireless transport module through serial ports; By the ZigBee wireless transport module body weight information is sent into the monitoring computer module, supply body weight information analysis and the record of monitoring computer the user.
The body weight information of described data collecting module collected human body; Pressure transducer adopts strain beam type pressure transducer; What measure is differential signal, and it has effectively suppressed the influence of difference mode signal, and the influence that intercept common-mode signal needs only the electric capacity of input termination at signal.
Described microcontroller is selected SN8P1937 for use; The inner integrated programmable gain amplifier of this microcontroller; A/D converter, LCD drives, and only needs the simulating signal of pressure transducer output is inserted the SN8P1937 microcontroller; Then the body weight information that collects is got final product through LCD display, communicate through simulative serial port and wireless transport module.
Described human-computer interaction module comprises key-press module and display module, and key-press module is mainly accomplished the calibration function of scale, adopts the point contact type button; Display module adopts liquid crystal display, because SN8P1937 has built-in lcd driver, driving comprises 4 common pins and 12 segment pins; The LCD timing for scanning takies 1/4 dutycycle; 1/2 or 1/3 bias voltage has 48 drivings, the LCDM1 register is provided with get final product.
Described wireless transport module adopts the ZigBee wireless transport module; ZigBee is a kind of short distance; The transmission mode of two-forty, the course of work is power saving very, can satisfy the demand of native system low power dissipation design; ZigBee module and microcontroller are through serial communication, and the body weight information that scale is measured sends on the computing machine.
The monitoring computer module writes down and analyzes the body weight information that receives; The user signed in in the data management system of oneself before measuring body weight; Computing machine is just to the record and the preservation of this measurement, and recent body weight information is analyzed, thereby realizes the monitoring to health.
