[specific embodiment]
For a better understanding of the technical solution of the present invention, being retouched in detail to the embodiment of the present invention with reference to the accompanying drawing
It states.
It will be appreciated that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Base
In the embodiments of the present invention, institute obtained by those of ordinary skill in the art without making creative efforts
There are other embodiments, fall within the protection scope of the utility model.
Fig. 1 is the structural schematic diagram of one embodiment of the signal receiving/transmission device for health-promotion kettle of the application.
With reference to Fig. 1, the signal receiving/transmission device 1 includes: sensor detection module 11, signal transmitting module 12, signal biography
Defeated module 13 and signal receiving module 14.Wherein, the sensor detection module 11 be used for the health-promotion kettle it is multiple to
Testing index is detected to obtain corresponding detection numerical value.The detection numerical value that the signal transmitting module 12 is used to obtain turns
It changes binary system into, is issued in the form of level place value (1 indicates that high level, 0 indicate low level) via signal output end, via described
Signal transmission module 13 is sent to the signal input part of the signal receiving module 14.The signal receiving module 14 is for receiving
Level place value, and level place value is converted into hexadecimal to be reduced into detection numerical value, and corresponding according to detection numerical generation
Control instruction.It is communicated between the signal transmitting module 12 and signal transmission module 13 by wireless communication mode.
Specifically, it continues to refer to figure 1, the sensor detection module 11 includes anti-overflow sensor 111, temperature detector
112 and liquid level detector 113.The signal transmitting module 12 includes the first chip 121, and first chip 121 has signal
Output end 122 (IO-OUT in Fig. 1).
In the present embodiment, the anti-overflow sensor 111 can use anti-overflow probe, for whether detecting in health-promotion kettle liquid
It overflows to obtain the first detection numerical value.The temperature detector 112 can use temperature sensor, for detecting liquid in health-promotion kettle
The temperature of body is to obtain the second detection numerical value.The liquid level detector 113, for detect the water level of liquid in the health-promotion kettle with
It obtains third and detects numerical value.In practical applications, according to the demand of index to be detected, can also be arranged in sensor detection module
Other detectors or sensor are for detecting corresponding index to be detected, and details are not described herein.
First chip 121 is by the multi-way detecting numerical value conversion obtained from the sensor detection module 11 at level position
It is worth and passes through the signal output end 122 and issues.For example, passing through anti-overflow sensor 111, temperature detector 112 and level sensing
The detection numerical value that device 113 obtains is usually the decimal system, and the decimal system can be converted into binary system by first chip 121, according to
Binary system can be converted the form of level place value, wherein 1 indicates that high level place value, 0 indicate low level place value.By different inspections
Surveying the detection numerical value that device (or sensor) detection obtains can be converted different level place values to distinguish.Then, via described
The signal output end 122 of first chip 121 issues level place value.
The signal transmission module 13 includes photo-coupler 131, and the photo-coupler 131 is connected to first chip
Between 121 signal output end 122 and the signal input part 142 of second chip 141.The signal receiving module 14 includes
Second chip 141, second chip 141 have signal input part 142 (IO-IN in Fig. 1).
Specifically, first chip 121 signal output end 122 issue level via the photo-coupler 131 at
Level is opposite after reason.
With reference to photo-coupler 131 shown in Fig. 2, the photo-coupler 131 includes that a light emitting diode and one are photosensitive
Triode (NPN type).Wherein, light emitting diode is usually adopted between the two as light emitting source and phototriode as light-receiving device
It is isolated with insulation transparent shell.
The working principle of the photo-coupler 131 is as follows:
Apply electric signal (according to first chip 121 in the anode and cathode (figure label 1 and 2) of light emitting diode
Signal output end 122 issue high level or low level determine), if applications electric signal be high level, LEDs ON
And light source is issued, light source is irradiated on phototriode, so that phototriode generates electric current, (i.e. collector c and hair is connected in ce
Emitter-base bandgap grading e conducting), export low level；If application electric signal is low level, light emitting diode ends, and gauge without light source is irradiated to photosensitive three
In pole pipe, phototriode cut-off is connected to 5V through resistance R15, exports high level.
Therefore, according to the working principle of photo-coupler 131 it is found that the signal output end 122 of first chip 121 issues
Level after photo-coupler is handled level it is opposite (i.e. high level is converted into low level, low transition into high level).
The level position transmitted via the photo-coupler 131 that the signal input part 142 of second chip 141 receives
After value, hexadecimal is converted thereof into be reduced into the detection numerical value, and control accordingly according to the detection numerical generation
Instruction.
In practical applications, signal output end 122 sends signal and signal input part 142 receives the time needs of signal together
Otherwise step will appear messy code, therefore send signal and receive the time one-to-one correspondence of signal.
Fig. 2 is the level schematic diagram of the receiving and transmitting signal of the signal receiving/transmission device for health-promotion kettle of the application；
In the present embodiment, the signal output end 122 guarantees transmitting-receiving letter by guidance code with the signal input part 142
Number time synchronization, and between the signal output end 122 and the signal input part 142 via photo-coupler 131 handle after,
The signal output end 122 is opposite with the level of the corresponding guidance code of the signal input part 142.
With reference to Fig. 2, signal output end issues 2ms high level and 2ms low level, signal input part receive 2ms low level
With 2ms high level；Wherein, 2ms is exactly guidance code.
In each level place value (data [0] [0] or data [0] [1] in Fig. 2, the wherein data that signal output end issues
[0] the level place value of [0] be 0, the level place value of data [0] [1] be 1) before require to be distinguished with guidance code, signal input
End is that rising edge starting receives level place value or failing edge starting receives level place value, is determined by the level of guidance code.Work as letter
The guidance code of number input terminal is high level after first low level, then starts in rising edge and receive place value.Conversely, when signal input part
Guidance code is low level after first high level, then starts in failing edge and receive level place value.
Further, it is after signal input part starts and receives level place value and complete guidance code reception with continued reference to Fig. 2
The place value received is more acurrate, is not that starting immediately receives place value, but preset time (such as 1ms) is waited to receive level again
Place value.That is, signal input part after rising edge starts and receives level place value, waits 3ms to start to receive level place value again.
It should be noted that the guidance code of signal input part is first in the level schematic diagram of receiving and transmitting signal shown in Fig. 2
High level after low level, therefore signal input part shown in Fig. 2 is to start to receive level place value in rising edge.In practical application
In, as described above, if the guidance code of signal input part is low level after first high level, starts in failing edge and receive level position
Value, therefore Fig. 2 is only schematic diagram, is not the restriction to the technical program.
