从而，本发明通过设置n个红外接收头，使得：当遥控器在多个红外接收头的红外遥控发射信号接收范围的重叠区域向红外遥控接收装置发送红外遥控发射信号时，控制器能接收到多个红外接收头输出的红外遥控接收信号，通过进行完整信号有效性校验，能够按照有效红外遥控接收信号控制被遥控设备进行相应遥控操作，而对于n个红外遥控接收信号均非有效红外遥控接收信号的情况，通过将n个红外遥控接收信号组合成组合红外遥控接收信号，并按照判断为有效的组合红外遥控接收信号控制被遥控设备进行相应遥控操作；因此，本发明能够在前述重叠区域提高红外遥控接收装置执行遥控操作的有效性，避免出现“n个红外遥控接收信号均非有效红外遥控接收信号”该情况而导致遥控操作失效；Thus, the present invention sets n infrared receiving heads so that: when the remote controller sends the infrared remote control transmitting signal to the infrared remote control receiving device in the overlapping area of the infrared remote control transmitting signal receiving range of multiple infrared receiving heads, the controller can receive The infrared remote control receiving signals output by multiple infrared receiving heads can control the remote control equipment to perform corresponding remote control operations according to the effective infrared remote control receiving signals through the complete signal validity verification, while the n infrared remote control receiving signals are not valid infrared remote control In the case of receiving signals, by combining n infrared remote control receiving signals into a combined infrared remote control receiving signal, and controlling the remote controlled device to perform corresponding remote control operations according to the combined infrared remote control receiving signal judged to be effective; Improve the effectiveness of the remote control operation performed by the infrared remote control receiving device, and avoid the situation that "n infrared remote control receiving signals are not valid infrared remote control receiving signals" and cause the remote control operation to fail;
其中，由于导致“n个红外遥控接收信号均非有效红外遥控接收信号”该情况出现的影响因素，主要有：对红外遥控发射信号存在干扰的环境因素，遥控器与红外遥控接收装置之间的遥控距离较远，遥控器在红外接收头的红外遥控发射信号接收范围的边缘位置进行遥控操作，遥控器发出的红外遥控发射信号的信号较弱；因此，本发明能够有效增强红外遥控接收的抗干扰能力、增加红外遥控接收的有效距离、增大红外遥控接收的有效角度范围、增强对信号较弱的红外遥控发射信号的适应性。Among them, the influencing factors that lead to the occurrence of "n infrared remote control receiving signals are not valid infrared remote control receiving signals" mainly include: environmental factors that interfere with infrared remote control transmitting signals, and the distance between the remote control and the infrared remote control receiving device. The remote control distance is relatively far, and the remote control is operated at the edge of the infrared remote control transmission signal receiving range of the infrared receiving head, and the signal of the infrared remote control transmission signal sent by the remote control is relatively weak; therefore, the present invention can effectively enhance the resistance of infrared remote control reception.

并且，相邻两个所述红外接收头之间的间隔距离使得：相邻两个所述红外接收头的无效遥控边缘区域S相互重叠，其中，遥控器在一个红外接收头的无效遥控边缘区域S发送红外遥控发射信号时，该红外接收头不能输出或者有概率不能输出所述有效红外遥控接收信号。And, the spacing distance between two adjacent infrared receiving heads is such that: the invalid remote control edge areas S of adjacent two infrared receiving heads overlap each other, wherein the remote controller is in the invalid remote control edge area of one infrared receiving head When S sends an infrared remote control transmitting signal, the infrared receiving head cannot output or has a probability of being unable to output the effective infrared remote control receiving signal.
从而，能够尽可能增大红外遥控接收装置进行红外遥控接收的有效角度范围，以及，尽可能增大n个红外接收头的红外遥控发射信号接收范围的重叠区域。Therefore, the effective angle range of the infrared remote control receiving device for infrared remote control reception can be increased as much as possible, and the overlapping area of the infrared remote control transmitting signal receiving ranges of n infrared receiving heads can be increased as much as possible.
