Embodiment
Basic principle of the present invention is: the waveform or the wave character data of storing various remote controller chips commonly used in electric equipment in advance, when the function button of the new remote controller of user definition, new remote controller is launched corresponding waveform, the electric equipment infrared receiving device send MCU to handle after receiving infrared signal, MCU with this waveform and storage or the wave character data relatively, waveform or wave character data according to the remote-controlled chip commonly used that prestores in the memory judge it specifically is which kind of yard type, call corresponding reception subprogram according to sign indicating number shape then, determine the code value of this waveform, activate this keypress function by the controller in the electric equipment simultaneously.
Electric equipment is that example describes with the television set in the embodiment of the invention.
As shown in Figure 1, mainly comprise for television equipment of the present invention: control device of the tv (the microprocessor MCU of reusable display device), memory EEPROM, image processing circuit, OSD treatment circuit, infrared remote receiver and remote controller.
Wherein, infrared remote receiver is used to receive the infrared signal that new remote controller sends, and from wherein demodulating control signal, the binary pulse waveform of control signal correspondence is sent to MCU;
MCU is used to receive the binary pulse ripple that infrared remote receiver transmits, and with television memory in advance the storage the wave character data compare, determine the sign indicating number type that this waveform is affiliated, determine corresponding code value according to the sign indicating number type then, activate keypress function according to remote control mode.
Memory EEPROM mainly deposits the waveform or the wave character data of the infrared emission chip that multiple remote controller commonly used uses.Specifically, can adopt following two kinds of storage modes:
(1) waveform is stored fully:
The operation principle of this storage mode is: the waveform of remote controller is one group (string) one group (string), and memory memorizes the remote control waveform of some remote-controlled chips commonly used fully.When the MCU of display device receives the waveform of one group of new remote controller by comparing the waveform of having deposited in determining whether to memory with the waveform of being stored of respectively organizing.Though this scheme needs bigger memory space, but, adopt this storage mode procedure quantity when carrying out the identification of new remote controller waveform smaller, and any unusual waveform can both memorize, because, system program can be that its validity is confirmed in one of a pulse pulsedly, determine it is 1 or 0 according to the width of each pulse, and with the displacement method with all the position receive, value in the register that displacement receives is exactly a key assignments, and the validity of pulse is identical with the identification of width for each pulse.
(2) wave character storage:
The principle of this storage mode is: because the coded system overwhelming majority that the remote-control transmitting chip on the market is adopted is use always several, as Toshiba, NEC, RC5, RCA etc., can be divided into two types of sign indicating numbers by modulation system, a kind of is to be the phase modulation of representative with RC5, and another kind is to be that the accent of representative is wide and have a pilot pulse with the Toshiba.For thinking that with a kind of modulation system the essential characteristic of remote control mode is identical, just the width of code element is different with number, therefore, adopt this storage mode not need to store too many information data, get final product and only need store some simple characteristics, these data volumes are also few, and the required storage resource seldom.The specific embodiment of the present invention is exactly to adopt this kind storage mode to deposit the wave character data of some remote controllers.For each remote controller code, we adopt 3 bytes to come the characteristics such as pulsewidth, customer number figure place and duplication code mode of mnemonic code type, " 0 " and " 1 ".1 byte memory customer number, 1 byte memory key, customer number combines with key forms complete remote control code value.When receiving the remote control pulse later on, confirmation code type is at first confirmed customer number and key after knowing yard type again, searches the key table that has activated simply and whether just can confirm effective key and confirm its function.
As shown in Figure 2, for adopting new remote control mode, the present invention activates the flow chart of keypress function.The user comprises following operating procedure when carrying out the definition of new remote controller key:
(1) user enters remote control mode and activates menu, and this activation menu comprises some basic function keys of TV, as electric power on/off key, channel switch key, volume+/-function keys such as key, quiet key;
(2) function of the required definition of selection;
(3) prompting of " the importing new remote controller code " that shows according to TV, the user sends a remote control mode by new remote controller to display device;
(4) display device MCU carries out the wave character analysis to the remote control pulse that receives;
(5) whether in advance display device MCU searches in memory, check the storage of above-mentioned remote control mode, if step (6) is changeed in storage in advance, otherwise changes step (10);
(6) user imports this remote control mode once more according to prompting;
(7) whether the remote control mode imported of determining step (3) and step (6) is identical, if identical commentaries on classics step (8), otherwise, step (9) changeed;
(8), selected function activated by new remote controller, setting completed;
(9), system provides miscue;
(10), system provides the prompting of " can not enable this remote controller ".
To be on the safe side, the menu prompt customer requirements is by twice button, confirms could real activation reinstate this key after errorless, can use in the user family other remote controllers to control TV.
In embodiments of the present invention, suppose that we prestore two kinds of remote control mode types of RC5 type and Toshiba's type in memory, then the signature analysis principle in the step (4) is as follows:
At first, whether MCU has the type that pilot pulse is judged this remote control mode according to the remote control mode that receives, if do not have pilot pulse, it then is the RC5 type, the reception subprogram of RC5 type codes is just called by system, if have pilot pulse, then be Toshiba's type, system just calls the reception subprogram of Toshiba's type codes.
Then, if the RC5 type, determine the width of " 0 ", " 1 " sign indicating number position respectively according to the width of the broad pulse of received remote control mode and burst pulse, thereby can confirm the figure place that pulse train comprises, again according to the characteristic of corresponding types in the system storage, and then can analyze the client's code value and the key value of this remote control mode.The principle of above-mentioned code value analysis is: because the pulse duration that various remote-controlled chips send has difference, but " 1 " of same chip and " 0 " pulse duration are fixed, therefore, the set of pulses of each button is pertinent establishes a capital the pulse of " 0 " and " 1 " two kinds of width, for a kind of new remote controller, as long as write down RC5 type or Toshiba's type, adopt dissimilar reception subprograms to analyze the figure place that institute's received pulse comprises then, and then definite remote control code value.The program resource that adopts this method to occupy is few, separates 3 times of size of code of single fixedly remote controller less than program, and taking of MCU time is close with former single remote control decoding.
After the function button of new remote controller activates, when the user uses new remote controller control television set, send a remote control waveform by remote controller, TV MCU is at first judged its yard type after receiving this remote controller waveform, adopt dissimilar reception subprograms to remove the remote control code value of this remote control waveform then, carry out the function of this remote control code value correspondence that is provided with in the above-mentioned setting program again.
