[0001] The invention relates to an infrared remote control receiving device, in particular to an infrared remote control receiving device capable of improving the effectiveness of remote control operation. Background Art

[0002] In the prior art, a remotely controlled device with an infrared remote control function adopts an infrared remote control receiving device provided with an infrared receiving head and a controller. The infrared receiving head receives the infrared remote control transmission signal, and the controller receives the infrared remote control receiving signal composed of logic 0 and logic 1 output by the infrared receiving head. Then, the infrared remote control receiving signal is processed into a check code by a checksum method, that is, according to preset operation methods such as negation, AND, OR, and Sum, to realize the validity check of the infrared remote control receiving signal: if the check code is the same as the preset value, the remotely controlled device is controlled to perform the remote control operation corresponding to the preset value.

[0003] The above existing infrared remote control receiving device has the following problems:

[0004] The infrared remote control transmission signal that can be received by the infrared receiving head is affected by many factors, which may cause the infrared remote control receiving signal output by the infrared receiving head to be distorted, that is, some bytes of the infrared remote control receiving signal are abnormal, which causes the processed check code to be different from each preset value, resulting in the failure of the remote control operation. Among them, the above-mentioned influencing factors include: environmental factors that interfere with the infrared remote control transmission signal, the remote control distance between the remote control and the infrared remote control receiving device is far, the remote control operation is performed at the edge of the infrared remote control transmission signal receiving range of the infrared receiving head, the infrared remote control transmission signal emitted by the remote control is weak, etc. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an infrared remote control receiving device that can improve the effectiveness of remote control operations, so as to solve the problem that the infrared remote control receiving signal output by the infrared receiving head of the existing infrared remote control receiving device is distorted due to various influencing factors, resulting in the inability to effectively control the remotely controlled device to perform corresponding remote control operations.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0007] An infrared remote control receiving device capable of improving the effectiveness of remote control operation is provided with an infrared receiving head and a controller, wherein the infrared receiving head is used to receive infrared remote control transmission signals, and the controller is used to perform corresponding remote control operations on the remotely controlled device according to the infrared remote control receiving signal output by the infrared receiving head; wherein the infrared remote control receiving signal is a string of data consisting of logic 0s and logic 1s.

[0008] Features:

[0009] The infrared remote control receiving device is provided with n infrared receiving heads, n≥2, and each infrared receiving head has a partially overlapping infrared remote control transmission signal receiving range with another or more infrared receiving heads;

[0010] The controller receives infrared remote control reception signals output by the n infrared receiving heads, and the controller remotely controls the remotely controlled device in the following manner:

[0011] Performing a complete signal validity check on the infrared remote control receiving signals output by the n infrared receiving heads to determine whether the infrared remote control receiving signals are valid infrared remote control receiving signals of the remotely controlled device;

[0012] If the infrared remote control receiving signal output by any one of the infrared receiving heads is a valid infrared remote control receiving signal, the remotely controlled device is controlled to perform a corresponding remote control operation according to the valid infrared remote control receiving signal;

[0013] If the infrared remote control receiving signals output by the n infrared receiving heads are not valid infrared remote control receiving signals, the n infrared remote control receiving signals are combined into a new infrared remote control receiving signal in the following manner, which is recorded as a combined infrared remote control receiving signal: first, each infrared remote control receiving signal is divided into m signal segments in sequence according to a preset division method, m ≥ 2, and are recorded as signal segments No. 1 to No. m in sequence; then, a segment signal validity check is performed on each signal segment to determine whether the signal segment is a valid infrared remote control receiving signal segment of the remotely controlled device, and a signal segment with a negative judgment result is recorded as an abnormal signal segment, and all abnormal signal segments are discarded; finally, the i-th signal segment of the n infrared remote control receiving signals that is determined to be a valid infrared remote control receiving signal segment is recorded as an abnormal signal segment. The i-th signal segment of the combined infrared remote control receiving signal is taken as the i-th signal segment of the combined infrared remote control receiving signal, 1≤i≤m, to be spliced ​​and combined into a combined infrared remote control receiving signal with the same signal length as the infrared remote control receiving signal; wherein, if the j-th signal segments of the n infrared remote control receiving signals are all abnormal signal segments, then a blank signal with the same signal length as the j-th signal segment is taken as the j-th signal segment of the combined infrared remote control receiving signal, 1≤j≤m; wherein, the preset segmentation method can be: dividing the infrared remote control receiving signal into m signal segments evenly according to the signal length, for example, dividing the infrared remote control receiving signal with a length of 21 bytes into three signal segments with a length of 7 bytes in turn; or it can be: dividing the infrared remote control receiving signal into m signal segments in turn according to preset unequal byte lengths.

[0014] For example: there are three infrared receiving heads that output infrared remote control receiving signals that are not valid infrared remote control receiving signals, and each infrared remote control receiving signal is divided into three signal segments, namely signal segment No. 1, signal segment No. 2 and signal segment No. 3 in sequence. After the segment signal validity check, it is determined that signal segment No. 1 of the first infrared remote control receiving signal, signal segment No. 2 of the second infrared remote control receiving signal, and signal segment No. 3 of the third infrared remote control receiving signal are all abnormal signal segments, and the remaining signal segments are all valid infrared remote control receiving signal segments. Then: signal segment No. 1 of the second infrared remote control receiving signal or the third infrared remote control receiving signal is used as signal segment No. 1 of the combined infrared remote control receiving signal, signal segment No. 2 of the first infrared remote control receiving signal or the third infrared remote control receiving signal is used as signal segment No. 2 of the combined infrared remote control receiving signal, and signal segment No. 3 of the first infrared remote control receiving signal or the second infrared remote control receiving signal is used as signal segment No. 3 of the combined infrared remote control receiving signal, thereby forming the combined infrared remote control receiving signal.

[0015] A complete signal validity check is performed on the combined infrared remote control receiving signal. If the combined infrared remote control receiving signal is a valid infrared remote control receiving signal of the remotely controlled device, the remotely controlled device is controlled to perform corresponding remote control operations. Otherwise, it is determined that the infrared remote control receiving signals output by the n infrared receiving heads this time are invalid signals, and the controller discards the n infrared remote control receiving signals and does not perform remote control operations on the remotely controlled device.

[0016] Among them, the controller performs complete signal validity verification on the infrared remote control receiving signal or the combined infrared remote control receiving signal as follows: the controller is preset with a valid verification code corresponding to each valid infrared remote control receiving signal of the remotely controlled device; the controller processes the infrared remote control receiving signal or the combined infrared remote control receiving signal into a verification code according to a preset verification operation method, and if the verification code is any valid verification code preset by the controller, the corresponding infrared remote control receiving signal or the combined infrared remote control receiving signal is a valid infrared remote control receiving signal of the remotely controlled device.

[0017] Among them, the controller performs segmented signal validity verification on the signal segment in the following manner: the controller is also preset with valid segment verification codes corresponding to m signal segments obtained by dividing each valid infrared remote control receiving signal of the remotely controlled device according to the preset segmentation method; the controller processes the signal segment into a segment verification code according to a preset verification operation method, and if the segment verification code is any valid segment verification code preset by the controller, then the signal segment is a valid infrared remote control receiving signal segment of the remotely controlled device, otherwise, the signal segment is an abnormal signal segment.

[0018] Among them, the preset verification operation methods used for the complete signal validity check and the segmented signal validity check can be the same or different.

[0019] Thus, the present invention sets n infrared receiving heads so that: when the remote controller sends an infrared remote control transmission signal to the infrared remote control receiving device in the overlapping area of ​​the infrared remote control transmission signal receiving range of multiple infrared receiving heads, the controller can receive the infrared remote control receiving signals output by the multiple infrared receiving heads, and by performing a complete signal validity check, the remotely controlled device can be controlled to perform corresponding remote control operations according to the valid infrared remote control receiving signals, and in the case where none of the n infrared remote control receiving signals are valid infrared remote control receiving signals, the n infrared remote control receiving signals are combined into a combined infrared remote control receiving signal, and the remotely controlled device is controlled to perform corresponding remote control operations according to the combined infrared remote control receiving signal that is judged to be valid; therefore, the present invention can improve the effectiveness of the infrared remote control receiving device in performing remote control operations in the aforementioned overlapping area, and avoid the situation where "n infrared remote control receiving signals are not valid infrared remote control receiving signals" causing the remote control operation to fail;

[0020] Among them, the factors that lead to the situation that "n infrared remote control receiving signals are not valid infrared remote control receiving signals" mainly include: environmental factors that interfere with the infrared remote control transmitting signal, the remote control distance between the remote control and the infrared remote control receiving device is far, the remote control is operated at the edge of the infrared remote control transmitting signal receiving range of the infrared receiving head, and the infrared remote control transmitting signal emitted by the remote control is weak; therefore, the present invention can effectively enhance the anti-interference ability of infrared remote control reception, increase the effective distance of infrared remote control reception, increase the effective angle range of infrared remote control reception, and enhance the adaptability to infrared remote control transmitting signals with weaker signals.

[0021] In addition, the n infrared receiving heads can be arranged in any manner as long as the overlapping area exists. By maximizing the overlapping area of ​​the infrared remote control transmission signal receiving range of the n infrared receiving heads, the performance of the infrared remote control receiving device of the present invention can be improved as much as possible.

[0022] A preferred embodiment of the present invention is given below: Figure 2 As shown, n infrared receiving heads are evenly spaced along the arc line, and the center line of the infrared remote control transmission signal receiving range of each infrared receiving head intersects at the center of the arc line after being extended.

[0023] Furthermore, the spacing distance between two adjacent infrared receiving heads is such that the invalid remote control edge areas of the two adjacent infrared receiving heads overlap with each other, wherein when the remote control sends an infrared remote control transmission signal in the invalid remote control edge area of ​​one infrared receiving head, the infrared receiving head cannot output or has a probability of not being able to output the valid infrared remote control reception signal.

[0024] 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 transmission signal receiving ranges of n infrared receiving heads can be increased as much as possible.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] First, the present invention sets n infrared receiving heads so that: when the remote controller sends an infrared remote control transmission signal to the infrared remote control receiving device in the overlapping area of ​​the infrared remote control transmission signal receiving range of multiple infrared receiving heads, the controller can receive the infrared remote control receiving signals output by multiple infrared receiving heads, and by performing a complete signal validity check, the remotely controlled device can be controlled to perform corresponding remote control operations according to the valid infrared remote control receiving signals, and in the case where none of the n infrared remote control receiving signals are valid infrared remote control receiving signals, the n infrared remote control receiving signals are combined into a combined infrared remote control receiving signal, and the remotely controlled device is controlled to perform corresponding remote control operations according to the combined infrared remote control receiving signal that is judged to be valid; therefore, the present invention can improve the effectiveness of the infrared remote control receiving device in performing remote control operations in the aforementioned overlapping area, and avoid the situation where "n infrared remote control receiving signals are not valid infrared remote control receiving signals" causing the remote control operation to fail;

[0027] Among them, the factors that lead to the situation that "n infrared remote control receiving signals are not valid infrared remote control receiving signals" mainly include: environmental factors that interfere with the infrared remote control transmitting signal, the remote control distance between the remote control and the infrared remote control receiving device is far, the remote control is operated at the edge of the infrared remote control transmitting signal receiving range of the infrared receiving head, and the infrared remote control transmitting signal emitted by the remote control is weak; therefore, the present invention can effectively enhance the anti-interference ability of infrared remote control reception, increase the effective distance of infrared remote control reception, increase the effective angle range of infrared remote control reception, and enhance the adaptability to infrared remote control transmitting signals with weaker signals.

[0028] Second, the present invention can maximize the effective angle range of infrared remote control reception of the infrared remote control receiving device and maximize the overlapping area of ​​the infrared remote control transmission signal receiving range of the n infrared receiving heads by evenly arranging n infrared receiving heads along an arc line and setting appropriate center line directions and spacing distances.

[0034] The infrared remote control receiving device is provided with n infrared receiving heads, n≥2, and each infrared receiving head has a partially overlapping infrared remote control transmission signal receiving range with another or more infrared receiving heads;

[0035] The controller receives the infrared remote control receiving signals output by the n infrared receiving heads, and the controller remotely controls the remotely controlled device in the following manner:

[0036] Performing a complete signal validity check on the infrared remote control receiving signals output by the n infrared receiving heads to determine whether the infrared remote control receiving signals are valid infrared remote control receiving signals of the remotely controlled device;

[0037] If the infrared remote control receiving signal output by any one of the infrared receiving heads is a valid infrared remote control receiving signal, the remotely controlled device is controlled to perform corresponding remote control operations according to the valid infrared remote control receiving signal;

[0038] If the infrared remote control receiving signals output by the n infrared receiving heads are not valid infrared remote control receiving signals, the n infrared remote control receiving signals are combined into a new infrared remote control receiving signal in the following manner, which is recorded as a combined infrared remote control receiving signal: first, each infrared remote control receiving signal is divided into m signal segments in sequence according to a preset division method, m ≥ 2, and are recorded as signal segments No. 1 to No. m in sequence; then, a segment signal validity check is performed on each signal segment to determine whether the signal segment is a valid infrared remote control receiving signal segment of the remotely controlled device, and a signal segment with a negative judgment result is recorded as an abnormal signal segment, and all abnormal signal segments are discarded; finally, the i-th signal segment of the n infrared remote control receiving signals that is determined to be a valid infrared remote control receiving signal segment is recorded as an abnormal signal segment. The i-th signal segment of the combined infrared remote control receiving signal is taken as the i-th signal segment of the combined infrared remote control receiving signal, 1≤i≤m, to be spliced ​​and combined into a combined infrared remote control receiving signal with the same signal length as the infrared remote control receiving signal; wherein, if the j-th signal segments of the n infrared remote control receiving signals are all abnormal signal segments, then a blank signal with the same signal length as the j-th signal segment is taken as the j-th signal segment of the combined infrared remote control receiving signal, 1≤j≤m; wherein, the preset segmentation method can be: dividing the infrared remote control receiving signal into m signal segments evenly according to the signal length, for example, dividing the infrared remote control receiving signal with a length of 21 bytes into three signal segments with a length of 7 bytes in turn; or it can be: dividing the infrared remote control receiving signal into m signal segments in turn according to preset unequal byte lengths.

[0039] For example: there are three infrared receiving heads that output infrared remote control receiving signals that are not valid infrared remote control receiving signals, and each infrared remote control receiving signal is divided into three signal segments, namely signal segment No. 1, signal segment No. 2 and signal segment No. 3 in sequence. After the segment signal validity check, it is determined that signal segment No. 1 of the first infrared remote control receiving signal, signal segment No. 2 of the second infrared remote control receiving signal, and signal segment No. 3 of the third infrared remote control receiving signal are all abnormal signal segments, and the remaining signal segments are all valid infrared remote control receiving signal segments. Then: signal segment No. 1 of the second infrared remote control receiving signal or the third infrared remote control receiving signal is used as signal segment No. 1 of the combined infrared remote control receiving signal, signal segment No. 2 of the first infrared remote control receiving signal or the third infrared remote control receiving signal is used as signal segment No. 2 of the combined infrared remote control receiving signal, and signal segment No. 3 of the first infrared remote control receiving signal or the second infrared remote control receiving signal is used as signal segment No. 3 of the combined infrared remote control receiving signal, thereby forming the combined infrared remote control receiving signal.

[0040] A complete signal validity check is performed on the combined infrared remote control receiving signal. If the combined infrared remote control receiving signal is a valid infrared remote control receiving signal of the remotely controlled device, the remotely controlled device is controlled to perform corresponding remote control operations. Otherwise, it is determined that the infrared remote control receiving signals output by the n infrared receiving heads this time are invalid signals, and the controller discards the n infrared remote control receiving signals and does not perform remote control operations on the remotely controlled device.

[0041] Among them, the controller performs complete signal validity verification on the infrared remote control receiving signal or the combined infrared remote control receiving signal as follows: the controller is preset with a valid verification code corresponding to each valid infrared remote control receiving signal of the remotely controlled device; the controller processes the infrared remote control receiving signal or the combined infrared remote control receiving signal into a verification code according to a preset verification operation method, and if the verification code is any valid verification code preset by the controller, the corresponding infrared remote control receiving signal or the combined infrared remote control receiving signal is a valid infrared remote control receiving signal of the remotely controlled device.

[0042] Among them, the controller performs segmented signal validity verification on the signal segment in the following manner: the controller is also preset with valid segment verification codes corresponding to m signal segments obtained by dividing each valid infrared remote control receiving signal of the remotely controlled device according to the preset segmentation method; the controller processes the signal segment into a segment verification code according to a preset verification operation method, and if the segment verification code is any valid segment verification code preset by the controller, then the signal segment is a valid infrared remote control receiving signal segment of the remotely controlled device, otherwise, the signal segment is an abnormal signal segment.

[0043] Among them, the preset verification operation methods used for the complete signal validity check and the segmented signal validity check can be the same or different.

[0044] Thus, the present invention sets n infrared receiving heads so that: when the remote controller sends an infrared remote control transmission signal to the infrared remote control receiving device in the overlapping area of ​​the infrared remote control transmission signal receiving range of multiple infrared receiving heads, the controller can receive the infrared remote control receiving signals output by the multiple infrared receiving heads, and by performing a complete signal validity check, the remotely controlled device can be controlled to perform corresponding remote control operations according to the valid infrared remote control receiving signals, and in the case where none of the n infrared remote control receiving signals are valid infrared remote control receiving signals, the n infrared remote control receiving signals are combined into a combined infrared remote control receiving signal, and the remotely controlled device is controlled to perform corresponding remote control operations according to the combined infrared remote control receiving signal that is judged to be valid; therefore, the present invention can improve the effectiveness of the infrared remote control receiving device in performing remote control operations in the aforementioned overlapping area, and avoid the situation where "n infrared remote control receiving signals are not valid infrared remote control receiving signals" causing the remote control operation to fail;
