Detailed description of the invention
Below by specific embodiment and combine accompanying drawing and the present invention is done further in detail
Describe.
As it is shown in figure 1, the control method of the controlled switch of embodiment of the present invention offer includes:
Step S101, first, second, third, fourth totally four preset time period are set.
Specifically, in step S101, the duration of the first preset time period can be 53-528
Microsecond, the duration of described second preset time period can be 116-174 microsecond, the described 3rd
The duration of preset time period can be 1.5-2 millisecond, the duration of described 4th preset time period
It can be 10-15 millisecond.Preferably, time a length of 528 microseconds of the first preset time period,
Time a length of 145 microseconds of the second preset time period, the 3rd preset time period time a length of 1.7
Millisecond, the 4th preset time period time a length of 12 milliseconds.It it is one with four preset time period
Cycle, but the time in whole cycle is less than 15ms, can detect 70 times in one second
Left and right, still ensure that the instruction being correctly detected extraneous existence.
Step S102, in the first preset time period, make radio receiving transmitting module detect remote controller
The instruction sent, if being not detected by instruction, then, after the first preset time period terminates, enters
Enter the second preset time period.
In actual applications, the duration of the first preset time period can be 53-528 microsecond, tool
Body ground, instructs and has certain length during sending, can be 5 bytes, also may be used
To be arranged to other byte lengths.Transmission and the reception synchronization of instruction are carried out, and namely instruct
The transmission time be exactly reception time of radio receiving transmitting module, be also the first preset time period
Minimum length, i.e. 53 microseconds.In order to ensure there is a complete instruction within the reception time,
Time a length of 528 microseconds of the first preset time period can also be selected.Remote controller is to wireless receiving and dispatching
The instruction that module sends is periodically transmission, in the first preset time period, wireless receiving and dispatching
The instruction that module detection remote controller periodically sends.May detection in the first preset time period
The instruction sent to remote controller, it is also possible to remote controller does not send instruction, wireless receiving and dispatching mould
Block then can't detect.
In step s 102, there is also a kind of possible situation, i.e. radio receiving transmitting module inspection
Measure instruction, if detecting, performing step S201-step S204, otherwise performing step
S103。
Step S103, in the second preset time period, make the wireless receipts to be received such as main control chip
Send out the instruction that module receives, if being not received by, then after the second preset time period terminates,
Enter the 3rd preset time period.
In step s 103, the length of the second preset time period can be 116-174 microsecond,
Preferably, a length of 145 microseconds of the second preset time period, this second preset time period
Length depend on the data channel speed of main control chip and radio receiving transmitting module and we to read
The command length gone out, when command length to be read is 5 bytes, the second Preset Time
A length of 145 microseconds of section, this value logic analyser is measured, certainly in reality
In the application of border, instruction a length of default, can be 5 bytes, it is also possible to be 4 bytes
Or 6 bytes, corresponding 116 microseconds or 174 microseconds respectively.Set different command lengths,
The length of the second preset time period is also different.The wireless receiving and dispatching to be received mould such as main control chip
The instruction that block receives, owing to radio receiving transmitting module is not detected by the finger that remote controller is sent to
Order, therefore main control chip does not instruct and can receive, and is not received by then the at main control chip
After two preset time period terminate, enter the 3rd preset time period.
Step S104, in the 3rd preset time period, make main control chip enter resting state,
After the 3rd preset time period terminates, enter the 4th preset time period.
Specifically, the length of the 3rd preset time period can be 1.5-2 millisecond, it is therefore preferable to
1.7 millisecond.In the length of the 3rd preset time period, main control chip and radio receiving transmitting module all open
Dynamic entrance resting state pattern, but radio receiving transmitting module also needs to state conversion time, this
It is to be determined by the characteristic of radio receiving transmitting module, and main control chip enters resting state almost
Moment.Therefore the 3rd preset time period is the state conversion time of radio receiving transmitting module.
Step S105, in the 4th preset time period, make radio receiving transmitting module enter dormancy shape
State；And after the 4th preset time period terminates, it is again introduced into the first preset time period.
Specifically, an instruction is sent 64 times by remote controller, is time-consumingly 14.373 milliseconds,
Correspondingly, a length of 14.373 milliseconds of the cycle therefore arranged, remove first pre-to the 3rd
If after the length of time period, a length of 12 milliseconds of the 4th preset time period.
In actual applications, the operating current in the first preset time period is 15mA, second
Operating current in preset time period is 3mA, and the operating current in the 3rd preset time period is
50uA, the operating current in the 4th preset time period is 10uA.The application can be obtained carry
Average current in the method for confession is:
(15mA*0.528ms+3mA*0.145ms+0.05mA*1.7ms+0.01mA*12ms)/(0.5
28+0.145+1.7+12) ms=8.56mAms/14.373ms=0.5956mA, relatively with existing
In technology, average current is that 10mA compares, and in the case of voltage is identical, the present invention provides
Method in the electric energy that consumed be far smaller than in prior art the electric energy consumed, the most permissible
Draw the control method of controlled switch using the present invention to provide, can greatly energy efficient.

Then make radio receiving transmitting module receive instruction, and after command reception, inform main control chip
Command reception is complete.
Specifically, wireless data transmission rate 1Mbps and we need the instruction that sends
Length determines that having sent an instruction needs 53us, and remote controller can again after the 422us of interval
Retransmit this instruction.In order to ensure have a complete instruction, institute in the first preset time period
With reception is set time for (422us+53us) * 2, with permissible in ensureing the first preset time period
Receive a complete instruction.

After order, this holding wire PTK is set high level.
Step S202, after main control chip knows command reception, to radio receiving transmitting module
Sending and obtain instruction, radio receiving transmitting module sends an instruction to main control chip.
In step S202, after main control chip detects that this holding wire PTK sets high level,
Main control chip sends to radio receiving transmitting module and obtains order, and entry instruction receives state, simultaneously
Holding wire PTK is set low level by radio receiving transmitting module, represents that instruction is by wireless receiving and dispatching mould
Block sends to main control chip.Instruction sends duration and depends on main control chip and wireless receipts
Send out the data channel speed of module and command length that we are to be read.
After step S203, instruction are read, main control chip is made to enter resting state.
In step S203, main control chip to radio receiving transmitting module send after sleep command from
Oneself is put into dormancy, and main control chip enters dormancy the most in a flash.
Step S204, make radio receiving transmitting module enter resting state, resting state continue the 4th
The instruction that remote controller sends again is detected after the duration of preset time period.
In step S204, radio receiving transmitting module enters dormancy needs one period of time,
Time is about 1.7 milliseconds, and this is to be determined by the characteristic of radio transmitting and receiving chip.Work as nothing
After line transceiver module and main control chip all enter resting state, controlled switch enters resting state,
Now power consumption reduces.The resting state of radio receiving transmitting module continues the 4th preset time period
