Description
Technical field
The invention belongs to the technical field of electric cooker, more particularly to a kind of weighing circuit of electric cooker.
Background technology
At present, electric cooker turns into indispensable household appliances in each family.As the improvement of people's living standards,
People also improve to the quality of diet and the requirement of taste.The present especially gradually accelerated in current people's rhythm of life
My god, many people want to scientifically carry out diet, it is desirable to be able to the quick rice for reasonably making delicious food, make it is suitable oneself
The rice of mouthfeel.Electric cooker traditional at present does not accomplish this point really, can only be with sensation when many times we cook
Go to add amount of rice, the quantization method of science can only be facilitated due to lacking, the rice made is often with feeling to add corresponding water amount
The preferable state required for oneself is not reached on appetite and mouthfeel.
The current rice cooker structure with function of weighing is nearly all the bottom that weighing sensor is positioned over to electric rice cooker body,
Such as patent application 201520600391.0, such a structure weigh electric cooker in its actual use function of weighing more not
Just, because majority's custom is all that interior pot is brought out to the operation that water is filled into luggage rice, to use its function of weighing, also needing will be interior
Pot is put into electric rice cooker body, and the comparison of weighing repeatedly when thus to follow-up adjustment water is inconvenient.
The content of the invention
Based on this, therefore the present invention primary mesh be to provide a kind of weighing sensor for being arranged at inner pan of electric cooker handle
Weighing sensor can be positioned over inner pan of electric cooker handle by circuit, the circuit so that people make when filling rice dress water before cooking
Progress is weighed can be with enhanced convenience, and weighs up using special circuit and processing procedure the weight of object in pot, Ke Yiti
Rise accuracy and anti-shudder performance that such a structure is weighed.
It is to provide a kind of weighing sensor circuit for being arranged at inner pan of electric cooker handle another mesh of the present invention, should
Circuit is weighed accurately, and realizes simplicity, with low cost.
It has been investigated that, weighing sensor is positioned over to the inner pan of electric cooker of inner pan of electric cooker handle, pot with hand end
When actually being weighed, influence is weighed and has at following 2 points：1. the inclination of low-angle, because people can not protect when normal end pot
How much the horizontality of card very, have slight inclination, but tilt the power for the gravity direction that sensor can be caused to receive
Reduce so that the signal message of sensor feedback is inaccurate, and then influence to weigh；2. people is difficult to keep away when holding pot during use
The small shake exempted from.People can produce the action of shake when pot is held when normal, even if naked eyes be can't see, these
Action extremely influences the Stability and veracity weighed, this factor be influence the structure weigh it is stable with accurately it is maximum because
Element.
To achieve the above object, the technical scheme is that：
A kind of weighing sensor circuit for being arranged at inner pan of electric cooker handle, it includes power supply, SOC (system-level cores
Piece), weighing sensor and display device, it is characterised in that the weighing sensor has two are respectively arranged at the two of electric cooker
In individual handle, the weighing sensor and display device are connected to SOC, and power supply is powered to SOC and display device.
The SOC mainly includes ADC, data processing module and I/O control modules, wherein, ADC and two
Weighing sensor is connected, and ADC is changed the signal that weighing sensor is obtained, and is transferred to data processing module, I/O controls
Molding block is connected to data processing module.
The display device can with LCD liquid crystal displays or charactron etc., according to display device be LCD screen, then contain in SOC
There are LCD drive modules.
Described two weighing sensors are respectively connected to SOC two-way AD detection mouths, or the first parallel connection of two sensors is again
Access a SOC AD detection mouth.
Further, AD collection can use the CSU8RP1381 in core sea with data processing unit SOC, and the SOC has 2
Road 24bit Sigma-Delta type high-precision adcs, interior band precision is ± 2% 8MHz oscillators, and 4 × 32/6 × 30 LCD drives
It is dynamic, the 48 programmable timers divided in advance.
The function of weighing for electric cooker of weighing is positioned on inner pan of electric cooker by the present invention, can be that user is more easily filling
Rice can overcome human hand in end pot because conventional jitter is with tilting the interference produced well with being weighed after dress water,
It is set not influence function of weighing so that it is accurate to weigh, and with anti-shudder performance.
Brief description of the drawings
Fig. 1 is the structural representation that the present invention is implemented.
Fig. 2 is the circuit theory diagrams that the present invention is implemented.
Fig. 3 is the structured flowchart that the present invention implements SOC.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Fig. 1 show the schematic diagram set weighing sensor with inner vessel for electrical cooking-vessel handle that the present invention is realized, by Fig. 1
It can be seen that weighing sensor is positioned at the handle 2 of pot in electric cooker 1 into we the two ends of the handle of pot need to all to be connected and weigh
Sensor S1 and S2, in run-off the straight, although two handle discontinuity, but overall stress is constant, so two one or two
The signal of weighing sensor common feedback at hand difference under inclination and non-tilt state less, inclined mesh is overcome to reach
's.
After the placement location for determining sensor S1, S2, also need to coordinate related sensor to detect and signal processing system, this
The circuit block diagram taken is invented as shown in Fig. 2 therein it can be seen that circuit mainly includes power supply, SOC, weighing sensor
And display device, wherein display device can be with LCD liquid crystal displays or charactron etc..
SOC module block diagram is as shown in figure 3, mainly there is ADC in SOC, data processing module and I/O control modules.If
The display device used it is also possible to use the SOC containing LCD drive modules for LCD screen, then.The wherein company of weighing sensor and SOC
Connecing can take as two weighing sensors are respectively connected to the mode of SOC two-way AD detection mouths in Fig. 2, it would however also be possible to employ two
Sensor first parallel connection accesses the form of a SOC AD detection mouth again.According to such as Fig. 2 connected mode when, it is necessary to access SOC
The two-way AD detection mouths at end, and need to do related algorithm processing to the AD of collection, according to current at the two-way AD reckonings of collection
Inclined state simultaneously extrapolates horizontality AD values.
In Fig. 1 circuit block diagram, AD collection and data processing unit SOC can use the CSU8RP1381 in core sea, should
SOC has 2 road 24bit Sigma-Delta type high-precision adcs, and interior band precision is ± 2% 8MHz oscillators, 4 × 32/6
