The present invention overcomes the deficiencies in the prior art, add identity code in the remote controller signal that employing is launched in remote controller, extract wherein identity code and the identity code comparison of stored authorized remote controller in advance after the television set reception remote signal, judge whether to authorizing the technical scheme of control of remote controller signal, limited of the operation of unauthorized remote controller to electrical equipment, for the user provides a kind of control device of electric appliance remote controller easily and effectively, satisfied user's demand.
Description of drawings
Fig. 1 is remote manipulator system of the present invention and remote control coding form schematic diagram;
Fig. 2 is an embodiment of the invention flow chart.
Embodiment
Basic principle of the present invention is to increase identity code in the remote control coding that remote controller sends, after the CPU of electrical equipment receives remote control mode, at first judge according to this identity code whether the remote controller that sends remote control coding is the remote controller that process is authorized, if, then carry out corresponding operation, otherwise do not carry out remote control command according to the remote control command control apparatus.
Be that example describes with the TV remote controller in the embodiment of the invention.
The system configuration of remote controller and the coded format of remote controller as shown in Figure 1, wherein remote controller comprises:
DC power supply is used for providing power supply to remote controller;
Key-press matrix is used for for user's input control order;
Control and remote control coding generation module are used for producing remote control coding according to the remote control command of user's input;
Amplifying circuit is used for the remote control coding signal is amplified;
Infrared transmission module is used for producing infrared waves, carrying remote control coding signal.
As shown in Figure 1, common remote control coding form is: guidance code+systematic code+numeric data code+data radix-minus-one complement.Wherein:
Guidance code: be used for notifying receiving terminal to be remote-control data thereafter;
Systematic code: being used for distinguishing is the data of which type, and receiving terminal judges according to this whether follow-up data are the instruction that must carry out;
Numeric data code: being used for distinguishing is which key is pressed, and receiving terminal is made the judgement that carry out what action according to numeric data code;
Data radix-minus-one complement: the correctness that is used for the verification msg sign indicating number.
The embodiment of the invention is inserted the identity code of remote controller in above-mentioned numeric data code, with 4 figure places signs, occupy preceding 4 of numeric data code, and each remote controller is provided with a unique identity code, and identity code is set in advance, can not change for example 0001.
Television set is stored the identity code of above-mentioned remote controller in its memory, after the control signal that receives the remote controller transmission, extract numeric data code in the remote signal coding preceding 4, the identity code that is stored authorized remote controller in the identity code of remote controller and the memory compares, if a certain in the identity code that receives and the identity code of storage is coincide, show that then the remote controller that this time sends remote control command is for authorizing remote controller, television set will be carried out remote command, otherwise, the television set refusal is carried out, and this remote controller can not be controlled television set.
For example, TV user is three remote controllers of its television set configuration, and wish to have only these three remote controllers can control television set, the identity code that can set these three remote controllers in advance is respectively 0001 (remote controller 1), 0010 (remote controller 2) and 0011 (remote controller 3), also stores these three identity codes in the television set in advance: 0001,0010 and 0011.
When remote controller 1, remote controller 2 or remote controller 3 during to the television set sending controling instruction, television set CPU extracts the identity code of storing in identity code and the television memory and compares from the remote control coding numeric data code, when identity code is in 0001,0010 or 0011 any, CPU can both find corresponding identification code in its memory, therefore can judge the remote controller that sends this remote signal for authorizing remote controller, CPU control television set is carried out function corresponding according to remote control command.
When other remote controllers outside remote controller 1, remote controller 2 and the remote controller 3 (as other TV remote controller of the same model of same brand) send remote signal to television set, identity code in its remote control coding numeric data code is not 0001,0010 or 0011 thrin, CPU can't find corresponding identity code at its memory, therefore judge that this remote controller is unauthorized remote controller, does not carry out corresponding remote control command.
In addition, for the rights of using of authorizing remote controller are limited, all right setting remote controller lock-out state, when authorizing remote controller that television set is carried out remote control, CPU can also require the user to import unlocking pin, if the unlocking pin of user's input is correct, then CPU control television set is carried out corresponding distant control function.
Embodiment of the invention flow chart comprises the steps: as shown in Figure 2
1, demodulates remote signal after the infrared signal of television set infrared receiving module reception remote controller input, and send remote controller signal to television set CPU;
2, television set CPU decodes to remote signal and extracts preceding 4 of numeric data code;
3, CPU with numeric data code preceding 4 with memory in advance the remote controller identity code of storage compare, if the identity code that conforms to is arranged in the memory, change step 4, otherwise change step 9;
4, CPU judges further whether this remote controller is in the lock state, if step 5 is changeed in locking, otherwise extracts the button code value in the numeric data code, and the control television set is carried out respective operations;
5, the button code value in the numeric data code is stored in the temporary storage, the prompting user imports unlocking pin;
6, the unlocking pin with user's input compares with the unlocking pin of presetting, if coupling is changeed step 7, otherwise changes step 8;
7, the CPU state that unlocks extracts the button code value in the temporary storage, and the control television set is carried out corresponding operation;
8, keep lock-out state, prompting user unlocking pin mistake;
9, this remote controller of prompting user is unauthorized remote controller.
