Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples:
Execution mode one:
See also the matching method of Fig. 1, wireless temperature measurement Electromagnetic Heating assembly of the present invention shown in Figure 2, described wireless temperature measurement Electromagnetic Heating assembly 10 comprises wireless temperature measurement cooking pot 11, electromagnetic heater 12, comprise drum 121, control circuit board 122, radio receiving unit 123 in the 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 fields obtain electric energy, and wireless transmission unit 112 sends the packet that includes 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, to examine simultaneously the pan identification code data record that is received by radio receiving unit 123 before the pot beginning is invalid code, control circuit board 122 detects the pan laying state n time continuously, wireless transmission unit 112 is after the success of each inspection pot, send packet, radio receiving unit 123 receive data bags;
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, compare this n group data, be no more than 50% if contain the ratio of identical pan identification code in the n group packet, be judged to be non-wireless temperature measurement cooking pot (being the common pan that is of placing on the electromagnetic heater), need not pairing; If the ratio that contains identical pan identification code in the n group packet then is judged to be wireless temperature measurement cooking pot greater than 50%, successful matching, control circuit board 122 control radio receiving units 123 only receive the packet that contains identical pan identification code.
In the present embodiment, establish the fixing pan identification code ID of 8bit in the described wireless transmission unit 112, the packet of its generation comprises:
| Initial code | The pan identification code ID | Temperature | Check code | End code |
Communication frame format is:
| Start byte | ID is high-order | The ID low level | Temperature is high-order | The temperature low level | Verification is high-order | The verification low level | End byte |
By every bit time 240uS, a frame time is 23mS, by sending calculated signals a second 3 times, be that every every 333mS of machine sends a secondary data, then channel capacity is 1000/3/23=14, and 14 wireless transmission unit 112 transmitted signals are namely arranged simultaneously, and its signal phase mutual interference is also less.
In the present embodiment, described inspection pot frequency n, 3≤n≤10.If inspection pot frequency n is less than 3, the probability that then receives 1 time is larger, and it is also large that it reaches 50% identical probability, easily produces erroneous judgement disconnected; If inspection pot frequency n is greater than 10, then the startup of wireless temperature measurement Electromagnetic Heating assembly 10 heating inspection pot is long, and the 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: pan is placed on the wireless temperature measurement Electromagnetic Heating assembly 10; Start, control circuit board 122 begins the inspection pot, after the success of each inspection pot, drum produces magnetic field, coil 113 these magnetic fields of induction obtain the electric energy of wireless transmission unit 112, radio receiving unit 123 receives the packet that includes the pan identification code ID that wireless transmission unit 112 sends, record is as 1 group of data, record successively 5 groups of data, then contrast the ratio of identical pan identification code ID in these 5 groups of data, if this ratio is no more than 50%, then judge the common pan that is of placing on the wireless temperature measurement Electromagnetic Heating assembly 10, need not pairing, control circuit board 122 is pressed ordinary pan control heating work; If contain the ratio of identical pan identification code greater than 50% in 5 groups of packets, then be judged to be wireless temperature measurement cooking pot, successful matching, control circuit board 122 control radio receiving units 123 only receive the packet that contains identical pan identification code ID, and other ID is not responded.
For avoiding the phase mutual interference of wireless signal, in the present embodiment, also be provided with random code on the described wireless temperature measurement cooking pot 11, after the successful matching, wireless transmission unit 112 is according to the delivery time of random code control packet.Described random code is surd not Repeating Field.For example, get an irrational number π, the First pan is got behind the decimal point 1～10 and is got 11～20 as parameter launch time for second for parameter launch time, and other by that analogy.Even a certain like this moment has produced communication contention aware, constantly will be different because of time parameter at next, automatically stagger, effectively avoid signal to disturb, thereby guarantee 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 that receives is heated in the control circuit board comparison again, if receive the pan identification code identical with previous successful matching, then be judged to be move the pot or the Electromagnetic Heating assembly enter the discontinuous operation pattern, if different from the pan identification code of previous successful matching, then return step S1, match.So, when the user does not shut down and when directly changing pot, control circuit board 122 can be controlled pairing again, avoid changing pot to cause radio receiving unit 123 not receive the pan identification code of successful matching of front, and misoperation, cause danger.And can distinguish intermittent-heating and change the difference that pot operates, need not repeatedly to repeat pairing.
The present invention adopts the identification of pan identification code, and by the identical pan identification code ratio that judgement receives, determine the pan kind on the electromagnetic heater, and then make differentiation, promote the adaptability of wireless temperature measurement Electromagnetic Heating assembly for pan, and then promoted its using value.And by identical pan identification code ratio, but the lower packet of filtering ratio reduces the interference between wireless signal.
In addition, in sending data procedures, random code is set, further reduces phase mutual interference, improving stability and reliability in the data transmission procedure.
Be appreciated that described random code is produced by pseudo-random function.So this nonessential variation is so also within protection range of the present invention.
