Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail:
Execution mode one:
See also the matching method of the wireless temperature measurement Electromagnetic Heating assembly of the present invention shown in Fig. 1, Fig. 2, described wireless temperature measurement Electromagnetic Heating assembly 10 comprises wireless temperature measurement cooking pot 11, electromagnetic heater 12, drum 121, control circuit board 122, radio receiving unit 123 is comprised in electromagnetic heater 12, wireless temperature measurement cooking pot 11 is provided with the coil 113 that temperature transducer 111, wireless transmission unit 112 and inductive electromagnetic heater 12 magnetic field obtain electric energy, and wireless transmission unit 112 sends the packet including temperature data and pan identification code.Described matching method comprises:
Step S1: start, control circuit board 122 empties the data of radio receiving unit 123, the pan identification code data record received by radio receiving unit 123 before simultaneously being started by inspection pot is invalid code, control circuit board 122 detects pan laying state n time continuously, wireless transmission unit 112 is after the success of each inspection pot, send packet, radio receiving unit 123 receives packet;
Step S2: pan identification, the packet that control circuit board 122 is received by radio receiving unit 123 with inspection pot number of times record n group, after removing invalid code, these n group data of comparison, if the ratio containing identical pan identification code in n group packet is no more than 50%, be judged to be not wireless boiler able to measuring temperature (what namely electromagnetic heater is placed is common pan), without the need to pairing; If the ratio containing identical pan identification code in n group packet is greater than 50%, be then judged to be wireless temperature measurement cooking pot, successful matching, control circuit board 122 controls radio receiving unit 123 and only receives the packet containing identical pan identification code.
In present embodiment, establish the pan identification code ID of a fixing 8bit in described wireless transmission unit 112, its packet occurred comprises:
| Initial code | Pan identification code ID | Temperature | Check code | End code |
Communication frame format is:
| Start byte | ID is high-order | ID low level | Temperature is high-order | Temperature low level | Verification is high-order | Verification low level | End byte |
By every bit time 240uS, a frame time is 23mS, by sending 3 calculated signals a second, namely the every 333mS of every platform machine sends a secondary data, then channel capacity is 1000/3/23=14, and namely have 14 wireless transmission unit 112 to send signal, its signal disturbs also less mutually simultaneously.
In present embodiment, described inspection pot frequency n, 3≤n≤10.If inspection pot frequency n is less than 3, then the probability receiving 1 time is comparatively large, and it is also large that it reaches 50% identical probability, easily produces erroneous judgement; If inspection pot frequency n is greater than 10, then the startup heating inspection pot of wireless temperature measurement Electromagnetic Heating assembly 10 is long, and user needs the wait of long period, is unfavorable for the use of product.Consider above problem, setting this inspection pot frequency n is 5 times, and detailed process is as follows: be placed on by pan on wireless temperature measurement Electromagnetic Heating assembly 10, start, control circuit board 122 starts to examine pot, after the success of each inspection pot, drum produces magnetic field, the electric energy that this magnetic field obtains wireless transmission unit 112 responded to by coil 113, radio receiving unit 123 receives the packet including pan identification code ID that wireless transmission unit 112 sends, record is as 1 group of data, record 5 groups of data successively, then the ratio of identical pan identification code ID in these 5 groups of data is contrasted, if this ratio is no more than 50%, then judge wireless temperature measurement Electromagnetic Heating assembly 10 is placed as common pan, without the need to pairing, control circuit board 122 is pressed ordinary pan and is controlled heating work, if the ratio containing identical pan identification code in 5 groups of packets is greater than 50%, then be judged to be wireless temperature measurement cooking pot, successful matching, control circuit board 122 controls radio receiving unit 123 and only receives the packet containing identical pan identification code ID, does not respond other ID.
For avoiding the mutual interference of wireless signal, in the present embodiment, described wireless temperature measurement cooking pot 11 is also provided with random code, after successful matching, wireless transmission unit 112 is according to the delivery time of random code control data bag.Described random code is surd not Repeating Field.Such as, get an irrational number π, after First pan gets decimal point, 1 ~ 10 is parameter launch time, and get 11 ~ 20 as parameter launch time for second, other by that analogy.Even if a certain like this moment creates communication contention aware, will be different because of time parameter at subsequent time, automatically stagger, effectively avoid signal disturbing, thus ensure the accuracy of radio communication.
In addition, described matching method also comprises: step S3, in the course of the work, the appearance of Electromagnetic Heating assembly is of short duration does not heat, and the pan identification code received is heated in control circuit board comparison again, if receive the pan identification code identical with previous successful matching, then be judged to move pot or Electromagnetic Heating assembly enters discontinuous operation pattern, if different from the pan identification code of previous successful matching, then return step S1, match.So, when user does not shut down and directly to change pot, control circuit board 122 can control pairing again, avoid changing pot cause radio receiving unit 123 do not receive before the pan identification code of successful matching, and misoperation, causes danger.And intermittent-heating and the difference of changing pot operation can be distinguished, without the need to repeatedly repeating pairing.
The present invention adopts the identification of pan identification code, and by judging the identical pan identification code ratio received, determining the pan kind on electromagnetic heater, and then making differentiation, improve the adaptability of wireless temperature measurement Electromagnetic Heating assembly for pan, and then promote its using value.Further, by identical pan identification code ratio, can the lower packet of filtering ratio, reduce the interference between wireless signal.
In addition, random code is set in transmission data procedures, reduces mutual interference, improving stability and reliability in data transmission procedure further.
Be appreciated that described random code is produced by pseudo-random function.So this nonessential change, so also within scope.
