Example 1
The embodiment provides an infrared detection management method.
Fig. 1 is a flowchart of an infrared detection management method provided in this embodiment, and as shown in fig. 1, the method mainly includes the following steps:
step S101, controlling a plurality of infrared emission devices to continuously transmit infrared signals, wherein the infrared signals transmitted by the infrared emission devices are different.
In an optional implementation manner of the embodiment of the present invention, in step S101, the multiple infrared transmitting devices may be controlled to transmit the infrared signals different from each other in a time division multiplexing manner, that is, time slots occupied by the infrared signals transmitted by the infrared transmitting devices are different from each other. In step S101, time slots occupied by the infrared transmitting devices may be pre-allocated, and when the infrared receiving device receives an infrared signal, the infrared receiving device may determine the infrared transmitting device that transmits the infrared signal according to the time slots occupied by the received infrared signal by demodulating the infrared signal.
In a specific implementation process, in step S101, the multiple infrared transmitting devices may also be controlled to transmit infrared signals different from each other in a frequency division multiplexing or code division multiplexing manner, which is not limited in this embodiment.
Step S102, whether a plurality of infrared receiving devices receive the infrared signals sent by each infrared transmitting device in the plurality of infrared transmitting devices within a preset time period is detected in sequence.
In this embodiment, the plurality of infrared receiving devices can all receive the infrared signal sent by each of the plurality of infrared transmitting devices, that is, the plurality of infrared receiving devices are all in the receiving range of each of the plurality of infrared transmitting devices.
In the implementation, taking time division multiplexing as an example, each infrared transmitting device occupies one or more predetermined time slots of one data frame, for example, assuming that 4 infrared transmitting devices including A, B, C and D in total and one data frame includes 8 time slots, the first and second time slots may be allocated to a, the third and fourth time slots may be allocated to B, the fifth and sixth time slots may be allocated to C, and the seventh and eighth time slots may be allocated to D. A occupies the first and second time slots of each data frame when sending infrared signals, B occupies the third and fourth time slots of each data frame when sending infrared signals, C occupies the fifth and sixth time slots of each data frame when sending infrared signals, D occupies the seventh and eighth time slots of each data frame when sending infrared signals, and each infrared receiving device can receive infrared signals in 8 time slots of a data frame under the condition of no shielding, therefore, the level output by the signal output end of each infrared receiving device is low level in each time slot of a data frame, when an infrared transmitting device takes A as an example, the sent infrared signals are shielded or the infrared transmitting device is in failure, the infrared receiving device can not receive the infrared signals sent by A, and the infrared signals are in the first and second time slots of the data frames, the level of the signal output terminal of the infrared receiving device becomes a high level. Therefore, by detecting the level variation waveform output from the signal output terminal of each infrared receiving device, it can be determined whether each infrared receiving device receives the infrared signal transmitted from each of the plurality of infrared transmitting devices.
When it is detected that one infrared receiving device does not receive the infrared signals sent by one or more infrared transmitting devices, according to the number of data frames continuously detecting that the time slots corresponding to the one or more infrared transmitting devices are at high level, the time when the infrared signals sent by the one or more infrared transmitting devices are not received can be determined, so that whether the predetermined time period is exceeded or not can be determined. And then according to the level variation waveform output by the equipment output end of each infrared receiving equipment, whether each infrared receiving equipment receives the infrared signal sent by each infrared transmitting equipment in a preset time period can be determined.
In the embodiment of the present invention, the preset time period may be set according to actual use, for example, may be set to 1 minute, and the embodiment is not limited in particular.
Step S103, under the condition that the plurality of infrared receiving devices are detected not to receive the infrared signals sent by the first infrared sending device in the plurality of infrared sending devices within the preset time period, marking the first infrared sending device as a fault device, and setting the first infrared receiving device which is preset to be used for receiving the infrared signals sent by the first infrared sending device in the plurality of infrared receiving devices as a device for receiving the infrared signals sent by the second infrared sending device in the plurality of infrared sending devices, wherein the second infrared sending device is not marked as the fault device.
In the embodiment of the invention, although one infrared receiving device can receive the infrared signals sent by a plurality of infrared transmitting devices, when detecting whether a person passes through the channel, the infrared receiving device only determines the infrared signals sent by one infrared transmitting device according to the receiving condition of each infrared receiving device. In a specific application, the infrared transmitting devices corresponding to the infrared receiving devices can be recorded, and the condition that the infrared signals are blocked is determined according to the receiving condition of the infrared signals sent by the infrared receiving devices to the infrared transmitting devices corresponding to the infrared receiving devices.
For example, in the infrared detection channel shown in fig. 2, there are A, B, C and D four infrared transmitting devices on the infrared transmitting device side, and there are 1, 2, 3 and 4 four infrared receiving devices on the infrared receiving device side, in this embodiment, the infrared receiving devices 1 and 2 can receive the infrared signals transmitted by the infrared transmitting devices a and B, and the infrared receiving devices 3 and 4 can receive the infrared signals transmitted by the infrared transmitting devices C and D. A. B, C and D transmit infrared signals in a time division multiplexed manner to prevent collisions.
In an initial state, the corresponding relationship between the infrared transmitting device and the infrared receiving device is set such that the infrared signal transmitted by the infrared transmitting device a is received by the infrared receiving device 1, that is, the infrared receiving device 1 is used for receiving the infrared signal transmitted by the infrared transmitting device a, the infrared signal transmitted by the infrared transmitting device B is received by the infrared receiving device 2, the infrared signal transmitted by the infrared transmitting device C is received by the infrared receiving device 3, and the infrared signal transmitted by the infrared transmitting device D is received by the infrared receiving device 4. If people or objects pass through the infrared receiving equipment, the received signals of the infrared receiving equipment 1, 2, 3 and 4 are sequentially shielded, and the door is judged to enter; otherwise, the receiving signals of the infrared receiving devices 4, 3, 2 and 1 are shielded in sequence, and the exit is judged; otherwise, it is triggered by error.
If the method provided by the embodiment of the invention is adopted, the infrared transmitting device A is detected to have a fault, that is, the infrared receiving devices 1 and 2 are detected not to receive the infrared signal sent by the infrared transmitting device A within the preset time period, the infrared transmitting device A is considered to have a fault, the infrared transmitting device A is marked to have a fault, the corresponding relation between the infrared transmitting device A and the infrared receiving device is modified, the infrared receiving device 1 is modified to be used for receiving the infrared signal sent by the infrared transmitting device B, meanwhile, the infrared receiving device 2 is kept unchanged for receiving the infrared signal sent by the infrared transmitting device B, that is, the corresponding relation between the infrared receiving device 2 and the infrared transmitting device B is kept. Similarly, when detecting that the infrared transmitting device C or D has a fault, the corresponding relationship between the infrared transmitting devices C and D and the infrared receiving devices 3 and 4 may be modified accordingly. Therefore, when one of the infrared emission devices A and B fails or one of the infrared emission devices C and D fails, the infrared detection system can continue to detect and monitor whether people or objects pass through the infrared detection channel, and the compatibility of the system to the faults is improved.
In the technical scheme provided by the invention, a plurality of infrared transmitting devices are controlled to transmit different infrared signals, for each infrared transmitting device, whether a plurality of infrared receiving devices in the receiving range of the infrared transmitting device do not receive the infrared signals transmitted by the infrared transmitting device within a preset time period is detected, if yes, the infrared transmitting device is determined to be in a fault, and the infrared receiving device which is originally set to be used for the infrared signals transmitted by the infrared transmitting device is modified to be used for receiving the infrared signals transmitted by other infrared transmitting devices which are not in the fault, except the infrared transmitting device, in the plurality of infrared transmitting devices. According to the technical scheme provided by the invention, when a certain infrared transmitting device fails, the infrared transmitting device corresponding to the infrared receiving device corresponding to the infrared transmitting device can be automatically modified into other infrared transmitting devices, so that the problem that the infrared detection result is inaccurate because the infrared receiving device cannot receive the infrared signal sent by the infrared transmitting device due to the failure of the infrared transmitting device is solved, and the accuracy of infrared detection is improved.
In a specific implementation process, in order to avoid misjudgment, for example, in the case where all of the plurality of infrared receiving devices are failed, the plurality of infrared receiving devices cannot receive the infrared signal sent by the first infrared transmitting device for a predetermined period of time, and if the first infrared transmitting device is marked as a failed device in this case, misjudgment occurs. Therefore, in an optional implementation manner of the embodiment of the present invention, before marking the first infrared emitting device as a faulty device, the method may further include: and determining that one or more infrared receiving devices in the plurality of infrared receiving devices receive the infrared signals sent by the infrared transmitting devices except the first infrared transmitting device in the plurality of transmitting devices within a preset time period. Through the optional implementation mode, the condition that the infrared transmitting equipment is judged to be failed by mistake due to the fact that all the infrared receiving equipment are failed can be avoided, and the judgment accuracy is improved.
In an optional implementation manner of the embodiment of the present invention, in order to continuously detect whether there is a failed infrared emitting device in the plurality of infrared emitting devices, after the first infrared receiving device is configured to receive the infrared signal sent by the second infrared emitting device, the method may further include: and returning to step S102 to continue to detect whether each of the plurality of infrared receiving devices receives the infrared signal sent by each of the plurality of infrared transmitting devices within a predetermined time period. With this alternative embodiment, it is possible to continue to detect whether there are any other infrared emitting devices that have failed after detecting that one infrared emitting device has failed, and it is possible to continue to detect whether there are any infrared emitting devices that have failed in the subsequent plurality of infrared emitting devices.
In an optional implementation manner of the embodiment of the present invention, in order to enable that, when it is detected that all infrared transmitting devices are normal, whether subsequent infrared transmitting devices have a fault can continue to be determined, when it is detected that all the plurality of infrared receiving devices receive an infrared signal sent by each of the plurality of infrared transmitting devices within a predetermined time period, the method further includes: step S102 is executed to continuously detect whether each of the plurality of infrared receivers receives the infrared signal sent by each of the plurality of infrared emitting devices in the next predetermined time period. With this alternative embodiment, it is possible to continuously detect whether any infrared emitting device among the plurality of infrared emitting devices has failed in the next preset time period.
