Micro-control unit) etc..As shown in figure 3, being connect for MCU100 of the present invention with low pressure detection module 200, infrared transmission module 300
Schematic diagram.Low pressure detection module 200 is connected to IO (input and output) mouth of MCU100, and the signal that will test is transmitted to MCU100,
Another I/O port of MCU100 is connect with infrared transmission module 300, by open signal and shutdown signal, such as high level signal and low

Infrared transmission module includes at least two-way driving circuit, the circuit structure of each driving circuit with drive in the prior art
The circuit structure of circuit is similar.As shown in figure 4, being the signal that infrared transmission module includes two-way driving circuit specific embodiment
Figure, LED_NET1, LED_NET2 are connect with the I/O port of MCU respectively, receive the open signal or shutdown signal of MCU output, wherein
Open signal is used for on-state drive circuit, and shutdown signal is for closing driving circuit.Driving circuit as shown in Figure 4 opens letter
Number be high level signal, shutdown signal is low level signal.It should be noted that circuit conducting is basis when high level
What the physical circuit determined, the present invention is not turned on and is limited to high level conducting, low level, i.e., in some cases,
Driving circuit is connected when low level also can be set, and driving circuit is not turned on when high level.
Existing infrared transmission module is driven using single channel, and battery makes after using for a period of time, and battery capacity can be reduced, electricity
Pressure can reduce, and the electric current for flowing through infrared transmitting tube can also reduce.In order to guarantee that remote controler can work normally, infrared transmitting tube is needed
Launch the light of some strength, electric current needs to be greater than certain value, so, as shown in Figure 1, existing resistance R can obtain phase
To smaller.It is will result in this way when battery just begins to use, the light that infrared transmitting tube is launched is too strong, wastes electric energy.In order to
The battery power of remote controler is saved, the resistance of driving circuit each in infrared transmission module is changed to the biggish electricity of resistance value by the present invention
Resistance.It is contemplated that effect in actual use, the resistance of each driving circuit should not be arranged very big.
Low pressure detection module realize mode there are many, when low pressure detection module implementation difference, how to determine to
The method of the number of the driving circuit of unlatching is not also identical.In one embodiment, the low pressure detection module may include each
Low-voltage testing circuit, the number of each low-voltage testing circuit fewer than the number for the driving circuit that the infrared transmission module includes 1.Example
If infrared transmission module includes 2 driving circuits, then low-voltage testing circuit is 1, and for another example infrared transmission module includes 3 drivings
Circuit, then low-voltage testing circuit is 2, and so on.
As shown in figure 5, each low-voltage testing circuit respectively include: first resistor R5, second resistance R6,3rd resistor R7, three
Pole pipe Q3, zener diode ZD1；The one end the first resistor R5 is connected to the ground, the positive phase of the other end and zener diode ZD1
Even；The one end second resistance R6 is connected with the anode of zener diode ZD1, and the other end is connected with the base stage B of triode Q3；Triode
Emitter E ground connection, collector C is connected with signal output end V_Detect, the one end 3rd resistor R7 respectively；3rd resistor R7 is another
One end, zener diode ZD1 cathode be connected respectively with power voltage terminal VCC；The zener diode ZD1 of each low-voltage testing circuit
Voltage of voltage regulation be all different, can detecte the voltage of different value.When the method for the present invention is realized by MCU, V_Detect is
Connect the I/O port of MCU.
V1 in Fig. 5 indicates the voltage of first resistor R5, second resistance R6 and the junction zener diode ZD1.Work as battery
When electricity is more sufficient, voltage is higher, and the voltage of V1 point is also relatively high, triode Q3 conducting, and the level at V_Detect is low
Level.With the use of battery, voltage is lower, and the voltage of V1 point is also lower, to a certain extent when, triode Q3 cut-off, V_
Level at Detect becomes high level.So the signal for passing through output is the electricity that low level and high level detect present battery
Amount, so that it is determined that needing to open a few road driving circuits to guarantee that its luminous intensity can satisfy demand.
On the basis of above-mentioned low pressure detection module, determined in the infrared transmission module for needing to open according to the signal
The step of number of driving circuit may include:
The number of high level in S1201, the detection signal；

For example, as shown in figure 4, infrared transmission module includes two-way driving circuit, as shown in figure 5, low pressure detection module packet
Containing a low-voltage testing circuit.Then the signal of V_Detect output is a high level or a low level.When low pressure detects mould
When block exports a low level, the number of high level is 0, then the number for the driving circuit for needing to open is 0+1=1, that is, is opened
The driving circuit all the way opened in Fig. 4 can meet demand.When low pressure detection module exports a high level, of high level
Number is 1, then the number for the driving circuit for needing to open is 1+1=2, i.e. two-way driving circuit in unlatching Fig. 4 is just able to satisfy and needs
It asks.
In another example as shown in fig. 6, infrared transmission module includes No. three driving circuits, as shown in fig. 7, low pressure detection module
Include two low-voltage testing circuits.Then the signal of V_Detect output is that a high level or a low level, V_Detect1 are defeated
Signal out is a high level or a low level.So the signal of low pressure detection module output are as follows: two low levels, one
High level and a low level, two high level.When low pressure detection module exports two low levels, the number of high level is 0,
The number for the driving circuit for then needing to open is 0+1=1, i.e. driving circuit all the way in unlatching Fig. 6 can meet demand.
When low pressure detection module exports a high level and a low level, the number of high level is 1, then the driving electricity for needing to open
The number on road is 1+1=2, i.e. two-way driving circuit in unlatching Fig. 6 could meet demand.When low pressure detection module exports two
When high level, the number of high level is 2, then the number for the driving circuit for needing to open is 2+1=3, i.e. unlatching tri- tunnel Fig. 6 Zhong
Driving circuit could meet demand.
When infrared transmission module and low pressure detection module are other situations, determine the number of driving circuit to be opened with it is upper
State that two examples are similar, and it will not be described here.

S120-1, according to preset each voltage range, determine the corresponding voltage range of the signal；
S120-2, according to the corresponding relationship of preset each voltage range and driving circuit number, determine that the signal is corresponding
Driving circuit number.
Assuming that each driving circuit conducting in high level that infrared transmission module includes, is not turned on, then MCU in low level
After the number for determining driving circuit to be opened, then the high level signal of corresponding number is sent to the driving circuit of selection,
Low level signal is sent to remaining each driving circuit.For example, as shown in figure 4, needing to open driving circuit all the way when determining
When, high level signal is exported and is connected to LED_NET1, Q1 by MCU, and low level signal is exported and is not turned on to LED_NET2, Q2.
When determination needs to open two-way driving circuit, MCU exports high level signal respectively to LED_NET1 and LED_NET2.
In addition, multiple keys can also be arranged in the present invention on the basis of remote controler, according to the triggering of different key number,
The emissive porwer for adjusting infrared transmitting tube, to change remote control distance.For example, when user wishes remote control distance farther out, Ke Yitong
When by two keys in remote controler, after MCU detects that the two keys are pressed, control triode Q1, Q2 conducting, so as to
The brightness of infrared transmitting tube is adjusted to adjust transmitting range.
