Reference picture 3, Fig. 3 are the schematic flow sheet of the anti-tampering embodiment of processing method one of infrared signal of the present invention.This implementation
In example, the anti-tampering processing method of infrared signal is applied particularly in the air conditioner provided with multigroup infrared sensor, including following step
Suddenly：
Step S10, the preparatory condition of each group of infrared sensor is obtained, wherein, each group of infrared sensor is respectively equipped with
Infrared emission head and infrared receiving terminal, preparatory condition comprise at least the coded format of infrared signal, in the working time set
It is any；
In the present embodiment, due to comprising at least an infrared emission provided with multigroup infrared sensor, one group of infrared sensor

And perform the associative operation to each group of infrared sensor.
In the present embodiment, preparatory condition have it is a variety of, than such as whether opening infrared detection etc., preferably the coding lattice of infrared signal
Formula and the working time of setting.The coded format of infrared signal refers to that it uses volume to infrared signal progress coded treatment
The mode of code is different, so as to obtain the infrared signal of different coding format.The working time of setting refers to infrared biography
The time of sensor operation.For example the infrared sensor working time can be set to every 20 minutes；Or it is set to some time in one day
Section, for example, 9 points to 21 points need open infrared sensor be operated, and other time section need not；Or it can be set on every Mondays
Open etc., specific setting time is unlimited.
Step S20, the infrared emission head transmitting infrared signal of each group and/or infrared receiving terminal is controlled to connect according to preparatory condition
Receive infrared signal.
In the present embodiment, each group infrared emission head transmitting infrared signal is controlled according to preparatory condition, when in certain distance
After being blocked and reflected by object (such as human body), the infrared signal of reflection is received (with specific reference to preparatory condition by infrared receiving terminal
Receive or do not receive).Specifically, blocked and reflected by object after only being launched due to infrared signal, just can be by infrared receiving terminal
Receive, thus infrared receiving terminal might not can receive the signal of infrared emission head transmitting every time, that is to say, that control

Carrier frequency sizes it is different.The infrared carrier wave signal of interference, such as the infrared carrier wave of air-conditioning remote control in current environment be present
Infrared carrier wave signal that signal, other group of infrared sensor are launched etc., therefore, to avoid judging by accident, infrared receiving terminal only receives pre-
If carrier frequency infrared carrier wave signal, the carrier signal without receiving other frequencies, and then the infrared biography of each group can be avoided
Interfering between sensor.For example infrared sensor 1 uses 38KHz, infrared sensor 2 uses 56KHz, infrared sensor 3
Using 64KHz etc..It should be noted that infrared sensor 1 uses 38KHz, i.e. the infrared emission head transmitting of infrared sensor 1 carries
The frequency of ripple signal is 38KHz, and the infrared receiving terminal of infrared sensor 1 only has response to 38KHz carrier signal；Infrared biography
Sensor 2 uses 56KHz, i.e. the frequency of the infrared emission head transmitting carrier signal of infrared sensor 2 is 56KHz, and infrared sensing
The infrared receiving terminal of device 2 only has response to 56KHz carrier signal.Each group of infrared sensor is by setting specific coding lattice
The carrier signal of formula, and then can be distinguished with other interfering carrier signals, and then avoid infrared detection from erroneous judgement being present and cause sky
Adjust device to run by mistake, improve the accuracy of infrared detection.
It is further alternative, in another embodiment of infrared sensor control process method of the present invention, using infrared signal
Coded format be infrared pulse signal, and coded format is pre-set, corresponding each group of infrared sensor.It is each group infrared
The pulse information for the infrared pulse signal that sensor is set differs, thus the infrared pulse of each group of infrared emission head transmitting
Signal also necessarily differs, and by setting the infrared pulse signal of specific coded format, and then can be distinguished with other groups, and
It can also be distinguished with other disturbing pulse signals, and then avoid infrared detection from erroneous judgement being present and cause air conditioner to run by mistake, carried
The accuracy of infrared detection is risen.Each group infrared receiving terminal receives the infrared pulse signal of transmitting, that is, each group infrared receiver
Head can receive same group or other groups or the infrared pulse signal of other interference.
Further alternative, the pulse information content of infrared pulse signal comprises at least number of pulses, level width, adjacent
The one or more in interval width between pulse.Number of pulses specifically refers to pulse in same pulse signal be present
Number, such as one or more pulses, level width specifically refer to the duration of pulse signal, the width tool between adjacent pulse
Body refers to the interval duration between adjacent pulse.In addition, encoded content can also include the umber of pulse of a transmitting cycle period
Amount, level width, pulse spacing width etc..
Reference picture 4, Fig. 4 are each group infrared emission hair in another embodiment of the anti-tampering processing method of infrared signal of the present invention
Penetrate the schematic diagram of infrared pulse signal.
Supplemented by assistant solve the default infrared pulse of each group infrared emission head in the anti-tampering processing method of infrared signal of the present invention
The pulse information of signal is different, and T1 is level width, interval widths of the T2 between adjacent pulse, as shown in figure 4, infrared
1 default infrared pulse signal of sensor is the infrared emission hair of Sing plus, T1=2ms, that is, the infrared sensor 1
The infrared pulse signal penetrated is Sing plus, T1=2ms；The number of pulses of 2 default infrared pulse signal of infrared sensor is
Three, T1=1ms, T2=5ms, T1 '=2ms, T2 '=4ms, T1 "=1ms；3 default infrared pulse signal of infrared sensor
Number of pulses be four, T1=1ms, T2=2ms, T1 '=1ms, T2 '=2ms, T1 "=1ms, T2 "=6ms, T1 " '=
1ms.In actual use, number of pulses can be more, receive infrared pulse signal for use in more accurately distinguishing and are
No is interference signal.
It is further alternative, in another embodiment of infrared sensor control process method of the present invention, by being set to each group
Different infrared pulse signals is put to be distinguish between, each infrared receiving terminal of above-described embodiment receive transmitting infrared pulse signal it
Afterwards, processor also performs following operation：
1st, decoding process is carried out to the infrared pulse signal received, obtains decoding data；
2nd, search in pulse information storehouse with the presence or absence of the pulse information to match with the decoding data；
If the 3rd, it is determined that infrared sensor corresponding to the infrared pulse signal；
4th, if not, it is determined that the infrared pulse signal is invalid signals.
In the present embodiment, infrared pulse signal is obtained after infrared signal is encoded, passes through infrared emission head transmission signal.When
The infrared pulse signal of transmitting is received through object emission by infrared receiving terminal.It should be noted that infrared emission head transmitting
It is the specific infrared pulse signal preset, and the pulse information of the infrared pulse signal of each infrared emission head transmitting not phase
Together, each infrared receiving terminal receives the signal of transmitting, that is, can receive different groups of infrared pulse signal, thus receives
After infrared pulse signal, also need to carry out decoding process to the infrared pulse signal of reception, obtain decoding data, that is, obtain pair
The pulse information answered.Pulse information storehouse is the database for the pulse information for being stored with the infrared pulse signal that each group is set.Base
In decoding data, search pulse information storehouse and whether there is the pulse information to match with decoding data, it is also just red by what is received
Outer pulse signal is contrasted with default missile infrared pulse signal, and the infrared pulse of reception is can determine whether out by contrast
Which group infrared sensor signal belongs to, that is, determines unique corresponding infrared sensor.Further, due to current environment
The infrared signal of multigroup infrared sensor transmitting is not only existed, while other interference signals such as remote control transmitting also be present, because
And when searching the pulse information less than matching, it may be determined that the signal received is interference signal, and then is determined as invalid signals,
In order to avoid infrared detection is judged by accident and causes air conditioner to run by mistake, and then improve the degree of accuracy.
Reference picture 5, Fig. 5 are transmitting and the infrared arteries and veins of reception in another embodiment of the anti-tampering processing method of infrared signal of the present invention

It is shown, that is to say, that the infrared pulse signal preset is receiving this process, last infrared receiving terminal by transmitting-reflection-
The information of the pulse signal received is consistent with the information for the pulse signal that infrared emission head is launched.Due to each group of infrared pulse
The default encoded content of signal is different, while each group of infrared sensor can be provided with multiple infrared emission heads, but as long as being same
The encoded content of one group of emitting head transmitting is consistent.Further, after which group infrared receiving terminal receiving signal regardless of, decoding
Corresponding encoded content is obtained, and then can determine that the infrared pulse signal received from which group infrared sensor transmitting.
It is further alternative, in another embodiment of infrared sensor control process method of the present invention, when preparatory condition is
During the working time of setting, according to the working time of each group setting, each infrared emission head and each infrared receiving terminal are controlled each
The self-corresponding working time carries out transmitting and receives infrared signal, wherein, the working time of each group of infrared sensor setting is each
Differ.By setting the different working times, so as to avoid being interfered between each group infrared sensor.It can specifically use and divide
When the method launched, for example when infrared sensor 1 works, infrared sensor 2,3,4 etc. is stopped, and infrared sensor 2
During work, other group of infrared sensor is stopped.
It is further alternative, each infrared emission head and each infrared receiving terminal are controlled each self-corresponding in above-described embodiment

2nd, if so, then obtain corresponding to infrared sensor, for the infrared emission hair for determining the infrared sensor
Penetrate infrared signal and infrared receiving terminal receives infrared signal；
3rd, if it is not, then control the infrared sensor of current non-working time infrared emission head suspend transmitting infrared signal with
And infrared receiving terminal shielding receives infrared signal.
In the present embodiment, because the working time of each group setting differs, thus by monitoring whether current time is each
The working time of group setting, if so, infrared sensor and being operated corresponding to then obtaining, if it is not, the then current non-working time
Infrared sensor do not work.For example infrared sensor 1 is set as that 00-20 hourly points are operated, infrared sensor 2 is set
It is set to 25-40 hourly points to be operated, infrared sensor 3 is set as that 45-58 hourly points are operated, current time
For 11: 00 when, control the infrared emission head transmission signal and infrared receiving terminal reception signal of infrared sensor 1, and infrared biography
Sensor 2,3 does not work, that is, suspends transmission signal and shield reception signal.Due to each group of infrared sensor working time not
Equally, thus mutual interference can be avoided, and then avoids infrared detection from erroneous judgement being present and cause air conditioner to run by mistake, lifting
The accuracy of infrared detection.
