Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model is described in detail.
Pressure sensitive body weigher of the present utility model is arranged on conventional soles, can be convenient for people to the body weight measuring oneself at any time, and weight data simultaneously can be shown by mobile phone screen to mobile phone by wireless network transmissions.
As shown in Figures 1 to 4, a kind of pressure sensitive body weigher, comprises the power supply for powering, voltage dependent resistor (VDR), single-chip microcomputer is connected with the input end of D/A modular converter with the D/A modular converter, the wireless module that are connected with single-chip microcomputer respectively, the output terminal of voltage dependent resistor (VDR).
Voltage dependent resistor (VDR) tiling is placed on the weight data that sole can produce user self, and be sent to D/A modular converter by measuring the simulating signal obtaining weight data, D/A modular converter here adopts the D/A modular converter of TLC5615CD model.
Above-mentioned simulating signal is converted to digital signal and sends single-chip microcomputer to by D/A modular converter, and single-chip microcomputer here adopts the single-chip microcomputer of STM32F103 model.Because STM32F103 single-chip microcomputer has a feature to be exactly low-power consumption, when not operating with mobile phone, whole system does not work, and whole system is in low power consumpting state, thus has saved the energy, when needs work, can wake whole system fast up and make its work.
Single-chip microcomputer sends digital signal to wireless module, also can receive the measurement instruction that wireless module is transmitted by mobile phone, carrys out control D/A modular converter and voltage dependent resistor (VDR) carries out surveying work.Described single-chip microcomputer is the core of whole functional realiey, needs process and the transmission of carrying out data, controls the progress of work of whole system, provides instruction successively enable them to perform work in proper order to modules.
Wireless module sends digital signal to mobile phone by wireless network and is presented on mobile phone screen, and wireless network here adopts the transmission mode of wireless blue tooth.
The utility model pressure sensitive body weigher, the data of its work display measurement are mainly from the change of the magnitude of voltage of voltage dependent resistor (VDR), to stand in this voltage dependent resistor (VDR) due to people thus resistance is changed, thus the magnitude of voltage in its circuit is changed, this analog quantity is converted into digital quantity, uses mobile phone to show the data of this measurement.User only needs to put on the footwear being provided with this device, a client installed by mobile phone, instruction is sent by cell-phone customer terminal---" measurement body weight ", this instruction is sent to the wireless module of this device by wireless blue tooth, single-chip microcomputer will accept this instruction, make voltage dependent resistor (VDR), D/A modular converter and wireless module work, finally in cell-phone customer terminal display data.
Pressure sensitive body weigher design philosophy of the present utility model is a design concept proposing based on the weather of current people mainly, design judicial convenience, popular and universalness.Secondly its is simple to operate, and use mobile phone to carry out operation and control, human-computer interaction interface is simple and convenient.Should be noted that 3 points when designing this and being arranged on the pressure sensitive body weigher of sole, first will anti-crushing, and the D/A modular converter for STM32F103 single-chip microcomputer and TLC5615CD will be noted can not by crushing; Second is damp proof; 3rd will note heat radiation, always how much can produce certain heat for when electronic product work.
The advantage of pressure sensitive body weigher of the present utility model has following several aspects: 1, this to be provided with the footwear of pressure sensitive body weigher with the outward appearance of common footwear and comfort level be all the same, and emphasis is only the measurement function of its inside; 2, the measurement for body weight is very easily, does not need the electronic scale specially with portable measured body weight; 3, adopt wireless communication mode, display screen do not installed by footwear, certain degree decreases damage, shown by mobile phone and seem convenient on the contrary.
Above embodiment is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection domain.
