Description
[technical field]
The utility model relates to a kind of mobile phone, especially refers to a kind of mobile phone with new auxiliary function.
[background technology]
Along with the high speed development of electronic industry, mobile phone has obtained in the whole world popularizing.Present most mobile phone has more had concurrently such as several data communication service functions such as short message receiving-transmitting, online, Mobile banking, mobile chatrooms except having good call function.And in order to satisfy the popular demand of consumption, it is light and handy, easy to carry and have a mobile phone of more auxiliary functions such as FM radio, electronic game etc. that each manufacturer releases structure one after another.This also becomes one of attraction of various mobile phones when bringing more convenience to people.Therefore, auxiliary function that mobile phone is new and value-added service become hot spot for competition new between the mobile phone manufacturer.
[utility model content]
The purpose of this utility model is to provide a kind of mobile phone with check weighing function, this kind mobile phone not only has the voice-and-data business function of common mobile phone, the weight of the electronic scale Measuring Object that can also show as a numeral, and behind input object unit price, can calculate and demonstrate the cost of testee.
The purpose of this utility model is achieved through the following technical solutions: the utility model mobile phone is provided with Weight-measuring device, described Weight-measuring device comprises central processing unit and the liquid crystal display module in elastomer, displacement transducer, A/D converter, the mobile phone, the weight that this Weight-measuring device can Measuring Object.
Described Weight-measuring device also is provided with the electric pressure converter that the supply voltage of mobile phone is converted to displacement transducer and A/D converter required voltage.
Elastomer in the described Weight-measuring device is contained in the receiving space of mobile phone housing sidewall.
Displacement transducer in the described Weight-measuring device is made up of slide rheostat, some resistance and operational amplifier.
Described Weight-measuring device is converted to the displacement that senses digital value and passes to central processing unit by A/D converter, and central processing unit is converted to digital value by the software interpolation computing method actual weight of object.
The utility model mobile phone is a kind of novel mobile telephone with weight measurement functionality.The novel mobile phone of this kind is except that possessing the mobile phone basic function, the weight of Measuring Object whenever and wherever possible, and, the Weight-measuring device that this mobile phone is provided with adopts numeral to show, can also calculate and show the cost of testee behind the input unit price, convenient, directly perceived, have application promise in clinical practice.

[embodiment]
See also shown in Figure 1ly, the utility model mobile phone 100 comprises main part 1, be located at main part 1 housing sidewall and roughly in a tubular form receiving space 2, be contained in the elastomer 3 in the receiving space 2 and be connected in the lid 4 at the housing edge of receiving space 2 open ends.Wherein, an end of elastomer 3 is fixed, and the other end is provided with hook, and to hang testee, lid 4 is substantially oblong-shaped, is covered in receiving space 2 open ends, with the protection hook.
See also shown in Figure 2ly, the Weight-measuring device of the utility model mobile phone 100 comprises central processing unit (hereinafter to be referred as CPU) and the liquid crystal display module (hereinafter to be referred as LCM) in elastomer 3, displacement transducer 10, A/D converter 11, the mobile phone 100.Wherein, elastomer 3 links to each other with displacement transducer 10, this displacement transducer 10 characterizes into different output voltage values with the displacement that the elastomer 3 that senses produces because of deformation, and deliver to A/D converter 11, and A/D converter 11 is converted to the CPU that digital signal is delivered to mobile phone 100 after the magnitude of voltage of input is sampled, quantizes, encoded, CPU converts the digital signal that receives to gravimetric value by the software interpolation computing method, and shows on the LCM of mobile phone 100.In addition, the Weight-measuring device of the utility model mobile phone 100 also is provided with electric pressure converter 12, be converted to the required voltage of displacement transducer 10 and A/D converter 11 with supply voltage, and be that displacement transducer 10 and A/D converter 11 are powered under CPU control mobile phone 100.
See also shown in Figure 3ly, displacement transducer 10 comprises slide rheostat S, resistance R 1, R2, R3, R4 and operational amplifier Y (being the LMV321 type product of National company in the present embodiment).The contact 20 that will drive slide rheostat S during elastomer 3 stress and deformations slides, thereby change the effective resistance on the slide rheostat S, this effective resistance and resistance R 2, R3 regulate the gain of operational amplifier Y jointly, make the output voltage V o of operational amplifier Y can satisfy the requirement of 11 pairs of signal input ranges of A/D converter.Resistance R 1 and R4 constitute voltage divider, with the input voltage of the Vin+ end of regulating operational amplifier Y.A/D converter 11 (being the ADC-10061 type product of National company in the present embodiment) is 10, be converted to 10 digital signal and pass to CPU after the analog voltage that is used for holding from the Vo of operational amplifier Y is sampled, quantizes, encoded, CPU converts the digital signal that receives to gravimetric value by the software interpolation computing method.The gained gravimetric value is exactly the size of elastomer 3 suffered pulling force, that is the gravimetric value of testee.The main composition element of electric pressure converter 12 is DC-DC converter P (being the LTC3200-5 type product of Linear company in the present embodiment), described DC-DC converter P comprises Vin end, SHDN end and Vout end, this DC-DC converter P is used for that Vin is held mobile phone 100 supply voltages of importing, and (2.7V～4.5V) be transformed to 5V from the output of Vout end is so that power for displacement transducer 10 and A/D converter 11.The pin of CPU is brought in startup or is closed DC-DC converter P by control SHDN.
See also shown in Figure 4ly, it is available after entering the weight measurement pattern, to weigh, weigh and valuate, proofread and correct three kinds of modes of operation.When mode is weighed in selection, testee is hung on the hook of elastomer 3, directly read gravimetric value from the LCM to get final product.Selection is weighed and during pricing mode, the input unit price hangs over testee on the hook of elastomer 3 more earlier, and CPU multiplies each other the gravimetric value that records automatically and draws cost with known unit price, and is presented at LCM and goes up and supply the user to read.In addition, in use for some time, the mechanical performance of elastomer 3 may change, and causes measuring producing than mistake, and can select correcting mode to proofread and correct this moment.After entering this mode, when the hook of elastomer 3 is vacant, select to proofread and correct start menu, key in gravimetric value 0 this moment, on the hook of elastomer 3, hang the known object of a gravimetric value then, and key in the actual weight value of this object, select this moment to proofread and correct and finish menu, CPU will carry out interpolation calculation according to the gravimetric value utilization correction program that records for twice, thereby finish calibration function.
The utility model mobile phone 100 is except that possessing the mobile phone basic function, by its set Weight-measuring device weight of Measuring Object whenever and wherever possible, and, described Weight-measuring device adopts numeral to show, can also show cost behind the input unit price, convenient, directly perceived, have application promise in clinical practice.
