按键识别方法及遥控器 Recognition method and remote control keys

技术领域 FIELD

[0001] 本发明涉及连续按键的识别方法,用于识别遥控器装置的按键操作是连续按键操作还是单个按键操作,本发明还涉及一种相应的遥控器。 [0001] The present invention relates to a method for continuous identification key for identifying the remote control key operation means is a key operation or a continuous operation of a single key, the present invention further relates to a corresponding remote controller.

背景技术 Background technique

[0002] 现有的遥控器中,都存在连续按键操作或者单个按键操作的使用状态,如何让控制单元识别是连续按键操作还是单个按键操作,从而使得遥控器发出正确的指令,是遥控器设计和制造的一个关键技术点。 [0002] In the conventional remote control, there is a continuous use status of a single button operation or the key operation, the control unit identifies how the key operation is a continuous or a single key operation so that the correct instruction from the remote controller, the remote controller is designed and made a key technical points.

[0003] 在红外遥控器中,一般采用的是NEC码进行红外遥控。 [0003] In the infrared remote control unit, is generally used in infrared remote control code NEC. 其连续按键操作的基本工作原理如下:当用户按下音量+/_、节目号+/_等按键并保持按下状态时,即为触发连续按键,在这种情况下,会先有一个命令码发出,然后是连续码,以后就只有一长串的连续码的重复发出,不再有命令码,直到用户松开按键。 The basic principle of successive key operation is as follows: When the user presses the volume + / _, program number + / _ like button is pressed and held state, i.e. continuous trigger button, in this case, will have a first order code issuing, continuous code is then, after only emits a continuous repetition of a long list of code, there is no command code, until the user releases the button. 每两个连续码之间的间隔是固定的110ms。 Each interval between two successive symbols is fixed 110ms. 原理波形图如图1所示,实际连续按键波形图如图2所示。 Principle waveform diagram shown in Figure 1, the successive key actual waveform diagram shown in FIG.

[0004] 可以看到NEC码包括一个命令码,其脉宽为110ms,无数个连续码,每两个连续码之间的间隔是固定的110ms。 [0004] It can be seen that NEC code comprising a command code, which is a 110ms pulse, numerous successive symbols, each interval between two successive symbols is fixed 110ms.

[0005] 由于红外遥控很容易受到外界干扰的影响而产生非法的连续码,例如用户轻触一下按键而误识别成连续按键,如图2所示,实际只是触发了一下按键,但从波形图上看,却产生了连续码而形成连续按键,这是因为人手的反应时间大于了IlOms所造成的。 [0005] Since the infrared remote controller are susceptible to outside interference generated continuous code illegally, the user taps a button, for example, is erroneously recognized as a continuous button, shown in Figure 2, but actually triggers a button, but the waveform of FIG. point of view, but that the continuous formation of successive key codes, because the time is greater than the manpower reaction IlOms caused.

[0006] 为了检测波形周期,已知的技术是大多采用固定的200ms或者400ms等定时来做检测周期。 [0006] In order to detect a waveform period, most of the known technique is to use a fixed 200ms or 400ms do peer timing detection period. 如每过200ms进行检测,看该时间段的前后是否有脉冲波形,如果200ms以后还有脉冲波形,则响应该脉冲波。 As every 200ms tested to see if the period of time before and after the pulse waveform, if there is a pulse waveform in response to the pulse wave after 200ms.

[0007] 这样的检测准确性不高,而且容易造成误操作。 [0007] Such detection accuracy is not high, but also easily lead to misuse. 发明内容 SUMMARY

具体实施方式 detailed description

[0026] 下面结合附图对本发明的具体实施例作详细的说明。 [0026] The following drawings of specific embodiments of the present invention will be described in detail in conjunction.

[0027] 本发明的目的在于提供一种通用的红外遥控的连续按键检测方法,具备两种保护机制,可以提高系统响应的准确性。 [0027] The object of the present invention is to provide a general infrared remote control button is continuously detecting method comprising two mechanisms, can improve the accuracy of the system response.

[0028] 现有红外遥控器的按键识别方法和检测周期,在背景技术已有交代,因为检测周期多为200或400ms,而连续按键的间隔周期为110ms,结合实际中红外接受到的信号是把发射的信号反向了的原因,导致,尽管只按下了一下menu键,却可能会出现一个连续按键的波形。 [0028] Key identification method and the conventional infrared remote detection period, the account has been in the background art, since the signal detection period 200 or more for 400ms, the continuous key interval period is 110ms, the actual mid-IR is received the transmitted signal is reversed reasons, resulting in, although only click the menu button is pressed, it may appear a continuous waveform button. 如图3所示,人工操作NEC码遥控器的波形图中,是单个按键产生的波形。 3, the manual operation waveform diagram of the NEC code remote control, a waveform is generated by a single key. 所以出现这种情况,是因为消费者在按键时按键时间可能超过110ms,就可能使得遥控器误识别为是连续的按键,因此,本发明为避免此误识别,设计了一种处理方法,即抛弃第一个连续按键。 Therefore this happens, because consumers may exceed 110ms time the key button, a remote controller such that it may be erroneously recognized as continuous key, therefore, the present invention is to avoid this erroneous recognition, a design approach, i.e., discard the first continuous button.

[0029] 故本发明主要是设置一个延时计数器,设定抛弃第一个连续按键,之后间隔110ms,进行周期性循环检测。 [0029] Therefore, the present invention is mainly provided a delay counter, a first continuous set abandon key, after an interval of 110ms, periodically loop detection. 具体可以设置一个500ms的延时装置,因为人的手进行单个按键操作的时间一般都在500ms以内,在连续码持续发送500ms后才认为是真正的连续按键产生。 Specific a 500ms delay means can be provided, because the time of a single human hand key operation are generally less than 500ms, the successive symbols before transmission 500ms duration considered true continuous key generation. 如果延时装置的延时时间太长,会导致前几个个按键误操作被遥控器延时计数器忽略掉,变成遥控器不能识别误操作,而延时时间太短,则还处在第一个连续按键周期内, 可能会导致单个按键操作尚未结束而被误识别为连续操作,从而丢失了单个案件操作,但是500ms的延时也是可以调整的。 If the delay time is too long delay means, several keys that might cause erroneous operation delay counter is ignored remote off into a remote control does not recognize the erroneous operation, the delay time is too short, it is still in the first button within a continuous cycle, may lead to be misidentified as a continuous operation of a single button operation is not over yet, so the loss of a single case of operation, but also a 500ms delay can be adjusted. 此处的IlOms时间间隔是根据码流的特性进行设定的, 主要就是为了提高检测精度,但此时间间隔可以调整。 IlOms time interval here is set according to the characteristics of the stream, mainly in order to improve the detection accuracy, but the time interval can be adjusted.

[0030] 参见附图6,所示下面详细介绍本发明遥控器实施例的设计和按键识别的过程: [0030] Referring to Figure 6, the process shown in the following detailed designs and embodiments of the present invention, the key identification of the remote control:

[0031] SO,首先对延时计数器进行初始化,并且预设定延时时间和循环检测周期。 [0031] SO, the delay of the first counter is initialized, and the pre-set delay time and loop detection cycle.

[0032] 首先需要对遥控器内的延时计数器进行初始化,并按需设定延时时间和检测周期。 [0032] First, the need to initialize the delay counter in the remote controller, and set the delay time needed and the detection period. 例如可以Set Key Command Delay Repeat (KEY DELAY 500MS, KEY REPEAT 110MS),这样就将检测连续按键的延时设置成了500ms,同时将检测周期设置成了110ms。 Examples Set Key Command Delay Repeat (KEY DELAY 500MS, KEY REPEAT 110MS), so that the detection will become a continuous delay setting key 500ms, while the detection cycle setting become 110ms. 这个数值可以进行微调,以满足不同的对象。 This value can be fine-tuned to meet the different objects.

[0033] Si,码流处理,经过码流处理,进入S2的按键响应,然后进入循环检测环节S3,检测后,判别是否为连续按键的S4步骤,如果不是连续按键则执行S7的退出步骤,如是连续按键,则进行S5的重复响应按键步骤,并判别是否有下一个连续码S6,如有则重复步骤S5, 如没有则执行步骤S7。 [0033] Si, stream processing, through the stream processing proceeds key S2 response, and then enters a loop detection segment S3, after the detection, it is determined whether step S4 successive key, if not a continuous button to exit step S7 is executed, successive key case, step S5 is repeated in response to the key is performed, and determines whether there is a continuous code S6, step S5 is repeated if, if no proceed to step S7.

[0034] 在用户按下按键时,控制单元首先会将这个按键解码并立即进行响应,同时触发延时计数器计数,进入连续按键的检测过程;当计数器达到500ms的设定时间时,如果此时仍然有连续码的存在,则以IlOms为周期,循环的检测是否有连续码,每周期内有一个连续码,则响应一次该按键。 [0034] When the user presses the button, the button control unit will first decode and respond immediately, trigger delay counter into successive key detection process; and when the counter reaches the set time of 500ms, if at this time there still exists a continuous codes, places IlOms cycle, the cycle is continuously whether a code, there is a continuous code per cycle, once in response to the key.

[0035] 下面介绍延时计数器的具体工作工程: [0035] The following describes specific work project delay counter:

[0036] 中断步骤:控制单元对接收到的按键信号进行解码,得到码流的脉宽,以及命令码和连续码。 [0036] Interrupt steps of: controlling the received key signal decoding unit to obtain pulse stream, and a command code and successive codes. 根据命令码,默认以单个按键操作的方式进行响应。 The command code, responds to the default mode of operation of a single key. 检测单个按键操作是否在延时计数器规定的时间内松开,如果松开,单个按键操作已经响应完毕,响应结束。 Detecting whether a single key operation for a predetermined release delay time counter, if released in response to a single key operation has been completed, in response to the end. 单个按键操作的判断方法具体为:对按键信号的红外NEC码进行接收,检测该NEC码的脉冲波是否有下降沿。 The method of determining a single key operation is specifically: NEC codes infrared key signals are received, detecting whether the NEC code pulse falling edge. 如果检测该NEC码的脉冲波有下降沿,则直接获取脉冲的宽度。 If the detected pulse has a falling edge of the NEC code, direct access to the pulse width. 如果没有,则判断在延时计数器设定的时间内该脉冲波是否结束,如果结束,则清除脉冲波的下降沿标志位, 判断长时间无按键时,则停止延时计数器工作,并回到初始化工作;如果在延时计数器设定的时间内该脉冲波没有结束,则获取脉冲的宽度。 If not, it is determined whether the pulse wave at the end of the delay counter set time, if the end flag is cleared falling edge of the pulse, it is determined that no key long, the delay counter stops working and return initialization; if the pulse does not end within the counter set time delay, the pulse width is acquired.

[0037] 循环检测步骤:如果超过了延时计数器规定的时间,则检测NEC码流的连续码,重复响应按键。 [0037] The loop detecting step: If the time delay counter exceeds a predetermined, continuous code is detected NEC code stream, in response to repeated key. 以IlOms为周期进行重复检测,看是否还有下一个连续码出现,如果有,则继续重复响应按键,直到检测没有下一个连续码为止。 In IlOms for repeat testing cycle, to see if there is a next successive code appears, if so, continues to repeat in response to the key, until the detection until there is no next sequential code. 本步骤的检测手段,主要是根据获取的脉冲宽度进行判断当前码的状态。 Detecting means of this step, the main current is determined according to the pulse width of the status code acquired.

[0038] 下面介绍脉冲宽度与当前码状态的判断过程,也即识别按键操作是单个还是连续的。 [0038] The following describes the process of determining the pulse width of the current state of the code, i.e. to identify a single key operation or continuous.

[0039] 在此由于本发明是基于一个典型的NEC码协议进行设计的,所以典型的NEC码协议逻辑队列的数据波形如图4所示,但是本发明并不限于使用NEC码协议,同样可适用于相应的其他码流协议。 [0039] Since this invention is based on a typical protocol NEC code design, the data waveform A typical protocol logic queue NEC code shown in Figure 4, but the present invention is not limited to use NEC code protocol, equally applied to the respective other bit stream protocols. 该协议中LSB (最低有效位)先于MSB (最高有效位)发送。 The agreement LSB (least significant bit) before the MSB (most significant bit) is sent. 每一帧波形由一个9ms的AGC脉冲开始,该脉冲用来设置初期IR接收器的增益。 Each frame waveform starting from a 9ms AGC pulses, which pulses are used to set the initial gain of the IR receiver. 紧跟着AGC (自动增益控制)脉冲的是4. 5ms的空闲,接着是8位的地址和8位的命令,地址和命令发送两次。 Followed by an AGC (Automatic Gain Control) 4. 5ms pulse is idle, followed by 8-bit address and 8-bit command, addresses and commands sent twice. 第二次发送时,所有的位取反,用来验证第一次发送的消息。 When the second transmission, all bit inverse, to verify that the message is first sent. 如果开发者不用验证,则可以忽略验证的数据,或者将地址或命令扩展为16位。 If developers do not have verification, data validation can be ignored, or the address or command extended to 16 bits. 一个消息只发送一次,即使是长按按键。 A message is sent only once, even if the press button. 当长按按键时,每隔IlOms发送一个重复的波形。 When pressing the button, every IlOms transmitting a repetitive waveforms. 该重复波形由一个9ms的AGC脉冲,2. 25ms的空闲以及560 μ s的脉冲构成,如图5所示。 The repetitive waveforms by the AGC pulses of a 9ms, idle and pulse 560 μ s 2. 25ms configuration, as shown in FIG.

[0040] 控制单元进行检测,得到当前码的周期宽度为13. 5ms时,判断为引导码状态。 [0040] The control unit detects the time period of the current code to obtain a width of 13. 5ms, boot code determines that state. 当前码的周期宽度为11. 25ms时,判断为系统码状态。 Width of the current cycle when the code is 11. 25ms, the system determines that the code state. 其他的判断为IDLE (空闲)状态。 Other determines IDLE (idle) state. 当判断为引导码状态时,检测脉宽是否符合引导码范围,不是,则返回,重新进行初始化工作。 When the state is determined as a boot code, the boot code detects whether the pulse width range, returns, re-initialization. 如果是的,则将其设置为系统码状态,循环进行下一次判断。 If it is, it is set to the state of the system code, the next one cycle is determined. 如果判断为空闲状态,则将其设置为引导码状态,初始化部分数据,并循环进行下一次判断。 If it is determined that the idle state, it is set to boot code state, part of the initialization data, and determines that a cycle. 当判断为系统码状态,现根据脉宽范围是否符合位范围,得到0/1的数列,循环检查至第16位,确定当前是系统码状态, 获得码值,并发送相应的按键值信息,且设定为空闲状态。 When it is determined that the system status code, a pulse width range according to whether the current position range, to obtain the number of columns 0/1, the first 16-bit loop check to determine the current state is a systematic code, access code value, and transmits the corresponding key value information, and it is set to the idle state. 再设置成引导码状态,检测脉宽是否符合连续码范围,如果是的,则进行延时,延时500ms并持续检测。 Further arranged to guide the state code, detecting whether the continuous code width range, if yes, proceeds delay, delay 500ms and continuously detected. 如果脉宽不符合连续码范围,则进行IlOms的周期循环,并发送相应的按键值,同时设定空闲状态。 If the pulse width does not meet the continuous code range, it is performed in cycles IlOms, and sends a corresponding key value, while setting the idle state.

[0041] 相应的,本发明设计的遥控器,一般包括延时计数单元、控制单元,在控制单元内包括检测单元和判别单元,通过码流的检测与判别,从而确定按键操作的模式,进而向被遥控装置发出红外信号。 [0041] Accordingly, the present invention is designed for remote control, a delay counting unit typically includes a mode, the control unit including a detection unit and a determination unit, and determining by detecting a code stream, so as to determine the key operation in the control unit, and then infrared signal is sent to the remote control device.

[0042] 为了进一步提高系统响应的准确性,可以给遥控器上的各个按键设定属性,并通过屏显菜单予以选择。 [0042] In order to further improve the accuracy of response of the system attributes to the keys may be set on the remote control, and to be selected through the OSD menu. 即设置对按键的连续按键是否响应,如果选择“响应”,则正常进行连续按键操作。 I.e., whether provided in response to successive key button, selecting the "response", then the normal key operation continuously. 如果选择“不响应”,则系统只相应一次按键,对该按键的其他相应脉冲,一概不予理会。 If "not responding", only the system corresponding to a key, the key of the other corresponding pulse invariably ignored.

[0043] 本发明设计的遥控器,除了应用在电视机上外,还可以用在机顶盒、DVD、空调等相应设备上。 [0043] The present invention is designed for remote control, in addition to the application on the TV, but also can be used in a respective device STB, DVD, air conditioning and the like.

[0044] 本发明由于设定了延时计数器,对控制系统形成了一个保护机制,这样就可以保证单键不被识别成连续按键,提高了系统响应的准确性。 [0044] Since the present invention sets the delay counter, the control system forms a protection mechanism, so as to ensure a continuous bond is not identified as a key to improve the accuracy of the system response.

[0045] 以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本领域的技术人员在本发明所揭露的技术范围内,可不经过创造性劳动想到的变化或替换,都应涵盖在本发明的保护范围之内。 [0045] The above are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art within the technical scope disclosed by the present invention, may occur through the creative work variations or replacements shall fall within the protection scope of the present invention. 因此,本发明的保护范围应该以权利要求书所限定的保护范围为准。 Accordingly, the scope of the present invention should be defined by the claims scope of protection as defined prevail.
