According to the vacuum cup with the digital display temperature, the digital temperature display device is increased in the vacuum layer of the internal wall and the external wall of the vacuum cup, the vacuum cup has a heat preservation function, meanwhile can display temperature of water inside the vacuum cup in real time, is convenient and safe and particularly suitable for the children, the aged, the patients or some people having special requirements.
Description
Technical field
The present invention relates to a kind of thermos cup, especially a kind of to the thermos cup of water temperature in thermos cup with real time temperature numerical monitor.
Background technology
Thermos cup is as the daily daily necessities of people, but frequency of utilization is very high., accidentally a lot, child or patient are easy to be arrived by the having one's hair waved of high temperature in cup, need for this situation the temperature designing a kind of feedback water in the cup that can be effectively real-time, avoid the danger be burned.
Summary of the invention
The object of the invention is to propose a kind of thermos cup with digital displaying temperature that can show temperature in cup effectively in real time.
To achieve these goals, technical scheme of the present invention is: a kind of thermos cup with digital displaying temperature, have one to be placed in glass at the bottom of the Temperature displaying control system of vacuum layer, a numeric display unit being placed in the vacuum layer of thermos cup inner and outer wall, described Temperature displaying control system comprises master controller, temperature sensor, temperature signal for measuring the water temperature in cup, and is sent to numeric display unit by master controller by temperature sensor, the water temperature value in display cup.
Digital temp display device is fixed in the vacuum layer of thermos cup bottom interior wall and outer wall, Circuits System and inwall is separated with heat-insulating shield.
The master controller of Temperature displaying control system is made up of AT89C51 single-chip microcomputer, ADC0804 analog to digital conversion circuit, 4 megadyne temperature degrees of data display circuits and peripheral power supply, clock circuit, temperature sensor completes the measurement of temperature and converts analog voltage signal to, the data signal that AT89C51 single-chip microcomputer can process is converted to via analog-digital converter ADC0804, then deliver in AT89C51 system and carry out process conversion, D4, D3, D2, D1 of finally temperature value being presented at numeric display unit are on totally 4 seven segment code light-emitting diode displays.
Temperature sensor is the digital thermometer of the 4 Digital sum pipe displays based on AT89C51.
Beneficial effect of the present invention:
1. the present invention is in temperature control, can measure the temperature range of 0 ° of C-99 ° of C, be shown to one decimal place.
2. the present invention is in Temperature displaying, realizes a temperature survey, reach the effect of real-time displays temperature by the every 30S of software simulating.
3. temperature display system of the present invention is arranged in the vacuum layer of thermos cup inner and outer wall, and Temperature displaying charactron is arranged on a glass body, can not affect the outward appearance of cup outside, is also convenient for people to observe temperature simultaneously.
The digital temperature thermos cup that the present invention proposes adds a temperature display system on the basis of original thermos cup, temperature display system for control core, adds AD590 temperature measurement circuit, ADC analog to digital conversion circuit, 4 megadyne temperature degrees of data display circuits and the composition such as peripheral power supply, clock circuit with AT89C51 single-chip microcomputer.The design of native system is intended to by the display to water temperature in thermos cup, shows be air themperature in current cup in time not having water in cup. and make the use of thermos cup more convenient and safe, good practical effect.
Accompanying drawing explanation
Fig. 1 is cup body structure schematic diagram of the present invention;
Fig. 2 is the present invention's temperature display system structure chart in an embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As Fig. 1, shown in 2, a kind of thermos cup with digital displaying temperature, by digital temp display device 2, Temperature displaying control system 5, bowl cover 1, thermos cup inwall 3, thermos cup outer wall 4, thermal cup vacuum layer forms.Temperature displaying control system 5 comprises master controller, temperature sensor, and temperature signal for measuring the water temperature in cup, and is sent to numeric display unit by master controller by temperature sensor, the water temperature value in display cup.A digital temp display device 2 is increased in the vacuum layer of thermos cup inwall 3 and thermos cup outer wall 4, while allowing thermos cup have insulation effect, the temperature of display insulation water in the cup that can also be real-time, not only convenient but also safety.Be particularly suitable for children, old man, patient or some have special requirement people use.
Traditional thermometer responds shortcomings such as speed is slow, reading trouble, certainty of measurement is not high, error is large and utilize AD590 Integrated Temperature Sensor Designation below and made the digital thermometer of a 4 Digital sum pipes displays based on AT89C51, its circuit is simple, software and hardware structure modularization, is easy to realize.
This digital thermometer utilizes AD590 integrated temperature sensor and interface circuit thereof complete the measurement of temperature and convert analog voltage signal to, the data signal that single-chip microcomputer can process is converted to via analog-digital converter ADC0804, then deliver in AT89C51 system and carry out process conversion, finally temperature value is presented at D4, D3, D2, D1 on totally 4 seven segment code light-emitting diode displays.
As shown in Figure 2, Temperature displaying control system 5 of the present invention is a kind of based on Embedded system, comprise: the controller being core with AT89C51 single-chip microcomputer, add AD590 temperature measurement circuit, ADC analog to digital conversion circuit, the sub-display circuit of the 4 megadyne temperature number of degrees and the composition such as peripheral power supply, clock circuit.
Wherein DS18B20 adopts external power supply mode to work, and line thermometric one line is connected with STC89C51, and the data measured are put in a register, and data are delivered to numeral method after binary-coded decimal conversion.DS18B20 temperature sensor is a kind of modified intelligent temperature sensor of the up-to-date release of DALLAS semiconductor company of the U.S., compared with the temperature elements such as traditional thermistor, it directly can read dut temperature, and can according to the digital value reading mode of actual requirement by simple programming realization 9 ~ 12.Because DS18B20 precision is higher, so within error criterion may be limited to 0.1 ° of C, in addition, the temperature-measuring range of-55 ° of C to+125 ° of C makes this thermometer be applicable to general application scenario completely, and the characteristic of its low voltage power supply can make battery powered electronic thermometer.
The present invention uses 4-digit number numeral method, temperature due to water is general not higher than 100, so the content of numeral method is: highest order shows ten megadyne temperature degree, and a second numeral method megadyne temperature degree, 3rd Digital sum pipe display decimal first, the group of four figures pipe unit of display ° C.
