Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an embodiment of a sensor fault processing method according to an embodiment of the present invention, and for convenience of description, only portions related to the embodiment of the present invention are shown. Specifically, the sensor fault processing method comprises the following steps:
s101, receiving a first environment illumination collected by a first sensor and a second environment illumination collected by a second sensor, wherein the first sensor and the second sensor are installed in the same environment, and the first sensor is in an enabling state.
Specifically, a first sensor and a second sensor are configured, the first sensor may serve as a main sensor, the second sensor may serve as a standby sensor, and the first sensor and the second sensor are both located in the same environment where the navigation aid lamp is located, and are used for detecting the ambient illuminance of the environment where the navigation aid lamp is located. The first sensor, which is the main sensor, is in an activated state, that is, the light intensity level of the navigational light is controlled according to the ambient illuminance detected by the first sensor. The acquisition time interval can be preset, and the first sensor and the second sensor acquire the ambient illuminance once every preset time to respectively obtain the first ambient illuminance and the second ambient illuminance.
S102, when the absolute value of the difference between the first ambient illumination and the second ambient illumination exceeds a set error value, judging that the first sensor has a fault.
That is, after receiving the first ambient illuminance collected by the first sensor and the second ambient illuminance collected by the second sensor, the difference between the first ambient illuminance and the second ambient illuminance is calculated. Since the first sensor and the second sensor are in the same environment in which the navigation light is located, if the first sensor is not in failure, the first ambient illuminance detected by the first sensor and the second ambient illuminance detected by the second sensor should be substantially equal, or the difference between the first ambient illuminance detected by the first sensor and the second ambient illuminance detected by the second sensor is very small. Therefore, the absolute value of the difference between the first ambient illumination and the second ambient illumination is compared with the set error value, and if the absolute value exceeds the set error value, the first ambient illumination detected by the first sensor is obviously lower than the second ambient illumination detected by the second sensor, and at this moment, the first sensor is judged to have a fault.
And S103, sending an alarm prompt, wherein the alarm prompt is used for prompting that the first sensor has a fault.
That is to say, when it is determined that the first sensor has a fault, an alarm prompt can be sent, the alarm prompt can be sent to the management terminal, and a manager can know that the first sensor has the fault through the management terminal, so that the manager can take maintenance measures in time, for example, replace the first sensor.
According to the sensor fault processing method provided by the embodiment of the invention, a first environment illumination collected by a first sensor and a second environment illumination collected by a second sensor are received, and the first sensor is in an enabling state; when the absolute value of the difference between the first ambient illumination and the second ambient illumination exceeds a set error value, judging that the first sensor has a fault; and sending an alarm prompt for prompting that the first sensor has a fault, in other words, the first sensor is used as a main sensor, the second sensor is used as a standby sensor, and because the first sensor and the second sensor are installed in the same environment, when the absolute value of the difference of the ambient illumination of the two sensors exceeds a preset error value, the first sensor is judged to have the fault, so that the automatic detection of the fault of the sensors can be realized, the related measures can be taken in time, and the normal work of the navigation aid lamp is ensured.
In some embodiments of the invention, further comprising:
switching the first sensor to a deactivated state and the second sensor to an activated state when the first sensor is malfunctioning.
The navigation aid lamp plays a warning role for the aircraft, so the normal work of the navigation aid lamp needs to be kept all the time, and the taking-off and landing safety of the aircraft is further ensured. In this embodiment, when the first sensor has a fault, the first sensor serving as the main sensor is switched to the deactivated state by control, and then the second sensor serving as the standby sensor is switched to the activated state, in other words, when the main sensor has a fault, the standby sensor is activated, the ambient illuminance of the environment where the navigation aid lamp is located is collected by using the standby sensor, and then the navigation aid lamp is controlled to normally work at a proper light intensity level, so that recovery processing of the fault is realized, and the taking-off and landing safety of the aircraft is ensured.
Referring to fig. 2, in some embodiments of the present invention, before determining that the first sensor has the fault, the method further includes:
s201, comparing the first environment illumination with a preset illumination range.
And S202, when the first ambient illumination is in the preset illumination range, executing the subsequent steps.
Since the first ambient illumination detected by the first sensor is usually relatively low, for example, 5lx, after the first sensor fails, in this embodiment, the magnitude of the first ambient illumination collected by the first sensor may be determined first. Specifically, a predetermined illumination range may be set, where the predetermined illumination range is generally small, for example, 0 to 10lx, and after the first ambient illumination collected by the first sensor is obtained, the first ambient illumination is compared with the predetermined illumination range to determine whether the first ambient illumination is within the predetermined illumination range, so that if the first ambient illumination is within the predetermined illumination range, the first sensor may have a fault.
However, since the ambient illuminance at night is relatively low, the first ambient illuminance collected by the first sensor is relatively low (i.e., the actual ambient illuminance) at night, in other words, even if the first sensor fails at night, the collected ambient illuminance is relatively close to the actual ambient illuminance, and therefore, if it is determined that the first sensor fails only by the fact that the first ambient illuminance is within the predetermined illuminance range, an erroneous determination may occur at night.
In this embodiment, it is determined whether the first ambient illumination is within a predetermined illumination range, and if so, the absolute value of the difference between the first ambient illumination and the second ambient illumination is continuously compared with a set error value, and it is determined whether the absolute value exceeds the set error value, where the error value is, for example, 10lx, and if the absolute value exceeds the set error value, the first ambient illumination is smaller than the second ambient illumination.
In an embodiment of the present invention, the step S101 further includes:
and sending a collection instruction, wherein the collection instruction is used for controlling a second sensor and a first sensor to collect the ambient illumination at the same time so as to obtain the first ambient illumination and the second ambient illumination.
Specifically, the collection time interval may be preset, a collection instruction is sent every predetermined time, and the first sensor and the second sensor collect the ambient illuminance once according to the collection instruction, so as to obtain the first ambient illuminance and the second ambient illuminance.
Because the first ambient illumination and the second ambient illumination are simultaneously acquired according to the acquisition instruction, if the first sensor has no fault, the first ambient illumination acquired by the first sensor and the second ambient illumination acquired by the second sensor are basically closer, and the error is very small, so that the accuracy of fault judgment can be ensured. And if the first ambient illumination and the second ambient illumination are respectively collected at a long time interval, because the weather may change in different time periods and the corresponding ambient illumination may be different, the weather change causes the ambient illumination collected by the first ambient illumination and the second ambient illumination to be obviously different, which easily causes fault misjudgment. In this embodiment, the first ambient illuminance and the second ambient illuminance that utilize to gather simultaneously can prevent the fault misjudgment that causes because of weather variation.
Referring to fig. 3, fig. 3 is a schematic structural diagram of an embodiment of a sensor fault processing apparatus provided by an embodiment of the present invention, and for convenience of description, only parts related to the embodiment of the present invention are shown.
