With the rapid development of the artificial intelligence technology, the sound processing technology and the image recognition technology are mature day by day, the invention mainly realizes the monitoring of the execution condition of the wind power locking experiment and the states of the local ventilator and the belt conveyer in the execution process based on the image recognition technology and the sound processing technology, and is convenient for operators to effectively monitor the wind power locking experiment process, thereby timely discovering, eliminating and recording various problems in the wind power locking experiment process.
The embodiment of the method for monitoring the wind power blocking experiment is described in detail below based on the method for monitoring the wind power blocking experiment. As shown in fig. 1, which is a flowchart of a method for monitoring a wind power blocking experiment provided in an embodiment of the present invention, a specific implementation process includes the following steps:
step S101: after receiving an indication signal which is sent by an application program in a client and used for indicating the start of a mine wind-electricity blocking experiment, triggering preset audio acquisition equipment to acquire audio data of an air duct air outlet of a local fan, and triggering preset video acquisition equipment to acquire video data of the shape of the air duct of the local fan.
In the embodiment of the invention, after the server receives the indication signal which is sent by the application program arranged in the client and used for indicating the start of the mine wind-electricity blocking experiment, the server can acquire the audio data of the air outlet of the air duct of the local ventilator at the moment by triggering the preset audio acquisition equipment, wherein the audio acquisition equipment can be equipment such as a mining intrinsic safety type sound pickup or an audio sensor.
It should be noted that the wind power locking experiment in the mine is usually performed once in 15 days, when the wind power locking experiment is performed, a maintenance manager needs to first send an indication signal for indicating the start of the wind power locking experiment in the mine to the server through an application program set in the client,
as shown in fig. 5, the audio collecting device 501 may be generally disposed in an air intake tunnel of a mine at a position about 10m away from a crossing of the excavation tunnel and the air intake tunnel (i.e., near an air outlet of an air duct of a local ventilator to reduce interference of noise of other devices), and may be preferably disposed right above the air outlet of the air duct of the local ventilator, so as to improve accuracy of detected audio data, and thus, a server may accurately obtain audio data generated by the local ventilator through the disposed audio collecting device.
Of course, the installation position of the audio capture device in the present invention is not limited to the above-mentioned situation, as long as it is sufficient to accurately acquire the audio data generated by the ventilator, and is not particularly limited herein.
After the preset audio acquisition equipment is triggered to acquire the audio data of the air duct air outlet of the local ventilator, the preset video acquisition equipment can be further triggered to acquire the video data of the air duct shape of the local ventilator.
In the embodiment of the invention, after the server receives the indication signal which is sent by the application program arranged in the client and used for indicating the start of the mine wind-electricity blocking experiment, the server can acquire the video data of the current wind cone shape of the local ventilator by triggering the preset video acquisition equipment. The video acquisition equipment can be video acquisition equipment such as a video camera, video monitoring equipment or a video recorder.
As shown in fig. 5, the video capture device 504 may be generally disposed at the intersection of the excavation roadway and the air intake roadway of the mine, so as to facilitate the simultaneous acquisition of the wind-barrel-shaped video data of the local ventilator and the video data of the running state of the belt conveyor, thereby enabling the server to simultaneously acquire the wind-barrel-shaped video data of the local ventilator through the disposed video capture device.
Similarly, the setting position of the video capture device in the present invention is not limited to the above-mentioned situation, and only needs to be satisfied that the audio data generated by the local ventilator can be accurately obtained, which is not described in detail herein.
It should be noted that, in an actual application scenario, the ventilation ducts of the air duct of the local ventilator are all made of soft materials, and therefore, the shapes of the ventilation ducts of the air duct may also change correspondingly according to the difference of the air volume. When the local ventilator is in a low-speed running state or a stop running state, the ventilation duct of the air duct is usually in a dry-shrivelled state, and when the local ventilator is in a high-speed or normal running state, the ventilation duct of the air duct is usually in a full state. The shape change characteristics of the air duct and the ventilation duct of the air duct can be identified through an image identification technology, so that the current running state of the local ventilator can be known.
Step S102: and determining the running state of the local ventilator according to the audio data and the video data of the air duct shape.
After audio data of an air duct outlet of the local ventilator and video data of an air duct shape are obtained in step S101, data preparation work is performed for analyzing the operation state of the local ventilator in this step. In this step, the operation state of the local ventilator may be accurately identified according to the audio data and the video data of the air duct shape.
In the embodiment of the present invention, the determining of the operation state of the local ventilator according to the audio data at the air outlet of the air duct and the video data of the shape of the air duct may be specifically implemented in the following manner:
a. firstly, a server can detect an audio decibel value corresponding to the audio data through an audio decibel measurement module, and extract the wind tube shape feature information in the wind tube shape video data by using a feature extraction algorithm. Then, the server may pre-construct an index combination including the audio decibel value and the air duct shape characteristic information, construct a first corresponding relationship between the audio decibel value, the air duct shape characteristic information, and an operation state of the local ventilator, and determine the operation state of the local ventilator corresponding to the index combination by using the index combination and the first corresponding relationship.
b. Firstly, a server can obtain an audio decibel value corresponding to the audio data through an audio decibel measurement module, compare the audio decibel value with a standard audio decibel value of an air duct air outlet of the local ventilator, and generate a corresponding first target parameter value for identifying the audio decibel value according to a comparison result. And judging whether a preset local ventilator air duct shape monitoring model is triggered to monitor the current air duct shape in the air duct shape video data or not according to the first target parameter value. Further, the characteristic information of the shape of the current air duct corresponding to the shape of the current air duct is obtained. Constructing a second corresponding relation between the air duct shape characteristic information and the running state of the local ventilator; and determining the running state of the local ventilator according to the current air duct shape characteristic information and the second corresponding relation.
In the specific implementation process, a local ventilator noise identification model, a local ventilator wind cylinder shape monitoring model and a belt conveyor belt running state monitoring model are preset in the server. The server can compare the audio decibel value with a standard audio decibel value of an air duct air outlet of the local ventilator through a local ventilator noise identification model, and generate a corresponding first target parameter value according to a comparison result.
For example: the standard audio decibel value of the air duct air outlet of the local ventilator can comprise: when the local ventilator is in a stop running state, the standard audio decibel value T1(T1 is less than or equal to 5dB) of the air outlet of the air duct; when the local ventilator is in a low-speed running state, the standard audio decibel value of the air outlet of the air duct is T2 (T2 is more than or equal to 5dB and less than or equal to 20 dB); and when the local ventilator is in a normal or high-speed running state, the standard audio decibel value of the air outlet of the air duct is T3 (T3 is more than or equal to 60dB and less than or equal to 85 dB). When the server identifies that the audio decibel value generated by the local ventilator is T4 through the local ventilator noise identification model, a corresponding first target parameter value is generated to be 1 when T4 is less than or equal to 5dB or 5dB is less than or equal to T4 is less than or equal to 20dB, and when the server identifies that the audio decibel value generated by the local ventilator is 60dB or less than or equal to T4 or less than or equal to 85dB through the local ventilator noise identification model, a corresponding first target parameter value is generated to be 0.
According to the first target parameter value, whether a preset local ventilator air duct shape monitoring model is triggered to extract air duct shape feature information in the air duct-shaped video data is judged, and the method specifically comprises the following steps:
when the first target parameter value is 1, triggering a preset local ventilator air duct shape monitoring model to extract air duct shape characteristic information in the air duct shape video data; and when the first target parameter value is 0, not triggering a preset local ventilator wind cylinder shape monitoring model to extract wind cylinder shape characteristic information in the wind cylinder shape video data. The local ventilator wind tube shape monitoring model is used for monitoring characteristic information of wind tube shape change conditions in the uploaded video data. And if the local ventilator air duct shape monitoring model monitors that the shape of the air duct is changed from full to flat, generating a second target parameter value to be 1, otherwise, generating a second target parameter value to be 0.
In an actual implementation process, a specific implementation time and a specific operation flow are usually set for a wind power blocking experiment, so that in order to improve the processing efficiency of audio data and video data and reduce the workload of image recognition, a time factor can be further considered when extracting the audio data acquired by the audio acquisition device and the video data acquired by the video acquisition device. Namely: extracting an audio data segment in a target time interval from the audio data, and identifying an audio decibel value contained in the audio data segment; extracting a video data segment in a target time interval from the video data with the air duct shape, decoding the video data segment into a corresponding video frame, and identifying air duct shape characteristics contained in the video frame based on an image characteristic identification algorithm; and determining the running state of the local ventilator according to the audio decibel value and the shape characteristic of the air duct.
Step S103: and when the running state meets the preset running state condition, obtaining the video data of the current running state of the belt conveyor.
In the embodiment of the present invention, when the operating state meets the preset operating state condition, the video data of the current operating state of the belt conveyor may be obtained through the preset video capture device, which specifically includes the following two conditions:
in the first case, when the operating state of the local ventilator satisfies the stop operating state condition, the video data of the current operating state of the belt conveyor acquired by the video acquisition device can be further obtained. In another case, when the operating state of the local ventilator satisfies the low-speed operating state condition, the video data of the current operating state of the belt conveyor acquired by the video acquisition device can be obtained, so as to perform the next analysis processing process. The low-speed running state refers to a running state of the local ventilator corresponding to the condition that the wind speed of the wind drum air outlet of the local ventilator is lower than a preset wind speed threshold value.
For example: when it is detected that the decibel value T of the audio generated by the operation state of the local ventilator is less than 5dB, it may be determined that the operation state of the local ventilator satisfies the stop operation state condition. When it is detected that the operating state of the local fan generates an audio decibel value T between 5dB and 20dB, it can be determined that the operating state of the local fan satisfies the low-speed operating state condition.
Step S104: and judging whether a power supply of the belt conveyor is in a power-off state at present according to the video data of the current running state of the belt conveyor, and if so, judging that the wind power blocking experiment is finished.
After the video data of the current running state of the belt conveyor, which is acquired by the acquisition device, is obtained in step S103, data preparation work is performed for judging whether the wind power blocking experiment is completed in this step.
In the embodiment of the present invention, the determining whether the power supply of the belt conveyor is currently in the power-off state according to the video data of the current running state of the belt conveyor specifically includes: generating a corresponding second target parameter value according to the running state of the local ventilator; triggering a preset belt conveyor monitoring model to extract running state characteristic information in the video data of the current running state of the belt conveyor according to the second target parameter value; and judging whether the current running state of the belt conveyor is a stopped running state or not according to the running state characteristic information, if so, judging that a power supply of the belt conveyor is in a power-off state, and if not, judging that the power supply of the belt conveyor is in a power-on state.
According to the second target parameter value, triggering a preset belt conveyor monitoring model to extract the running state characteristic information in the video data of the current running state of the belt conveyor, and specifically comprising the following steps:
when the second target parameter value is 0, the preset belt conveyor monitoring model is not triggered to extract the running state characteristic information in the video data of the current running state of the belt conveyor. The belt conveyor monitoring model is used for monitoring running state characteristic information of the belt conveyor in the uploaded video data. And if the belt conveyor monitoring model monitors that the conveying state is changed from running to stopping, generating a third target parameter value to be 1, otherwise, generating a third target parameter value to be 0. Wherein: and generating a third target parameter value of 1 to represent that the wind power blocking test is completed, and generating a third target parameter value of 0 to represent that the wind power blocking test is not completed. If the wind power locking test in the mine is judged not to be completed, the server can generate corresponding alarm indication information, and sends the alarm indication information to the authenticated mobile terminal equipment through a preset communication device, so that maintenance management personnel are informed in time, and the field fault analysis and treatment are facilitated for the maintenance management personnel.
In the actual implementation process, when the power supply of the belt conveyor is judged to be in the power-off state currently, a first record log used for indicating that the wind power blocking experiment is completed can be generated; when the power supply of the belt conveyor is judged to be in the electrified state currently, a second recorded log used for indicating that the wind power blocking experiment is not completed can be generated, the first recorded log and the second recorded log are stored in a data storage system in a server, and visual display can be carried out through a touch display screen on equipment, so that maintenance and management personnel can conveniently check the logs subsequently.
It should be noted that the wind power locking described in the present invention means that after the local ventilator which normally works stops operating or when the wind speed in the wind drum is lower than a specified value, the local ventilator can automatically trigger to cut off the power supply of the non-intrinsically safe electrical equipment in the wind supply area, and when the local ventilator recovers normal ventilation or the wind speed in the wind drum is higher than the specified value, the power supply of the non-intrinsically safe electrical equipment can normally supply power to operate. Therefore, the power supply of the non-intrinsic safety electrical equipment in the wind stop area can be automatically cut off after the local ventilator which normally works stops running or stops wind. The explosion caused by interaction of the gas concentration rise in the tunnel and the electrified power supply equipment after the local ventilator stops running or when the wind speed in the wind barrel is lower than a specified value is effectively avoided.
By adopting the method for monitoring the wind power locking experiment, whether the process of the wind power locking experiment is successfully completed according to the specified flow can be accurately monitored by identifying the running states of the local ventilator and the belt conveyer, the efficiency of monitoring the wind power locking experiment is improved, and complicated operation steps are avoided, so that the use experience of a user is improved.
Corresponding to the method for monitoring the wind power locking experiment, the invention also provides a device for monitoring the wind power locking experiment. Because the embodiment of the device is similar to the method embodiment, the description is relatively simple, and please refer to the description of the method embodiment, and the embodiment of the device for monitoring the wind power blocking experiment described below is only schematic. Fig. 2 is a schematic view of a device for monitoring a wind power blocking experiment according to an embodiment of the present invention.
The device for monitoring the wind power locking experiment comprises the following parts:
the data acquisition unit 201 is configured to acquire audio data of an air duct outlet of the local ventilator and acquire video data of an air duct shape of the local ventilator after receiving an indication signal, sent by an application program in a client, for indicating that an in-mine wind-power blocking experiment starts.
In the embodiment of the invention, after the server receives the indication signal which is sent by the application program arranged in the client and used for indicating the start of the mine wind-electricity blocking experiment, the server can acquire the audio data of the air outlet of the air duct of the local ventilator at the moment by triggering the preset audio acquisition equipment, wherein the audio acquisition equipment can be equipment such as a mining intrinsic safety type sound pickup or an audio sensor.
It should be noted that the wind power locking experiment in the mine is usually performed once in 15 days, and when the wind power locking experiment is performed, a maintenance manager needs to send an indication signal for indicating the start of the wind power locking experiment in the mine to the server through an application program set in the client.
As shown in fig. 5, the audio collecting device 501 may be generally disposed in an air intake tunnel of a mine at a position about 10m away from a crossing of the excavation tunnel and the air intake tunnel (i.e., near an air outlet of an air duct of a local ventilator to reduce interference of noise of other devices), and may be preferably disposed right above the air outlet of the air duct of the local ventilator, so as to improve accuracy of detected audio data, and thus, a server may accurately obtain audio data generated by the local ventilator through the disposed audio collecting device.
Of course, the installation position of the audio capture device in the present invention is not limited to the above-mentioned situation, as long as it is sufficient to accurately acquire the audio data generated by the ventilator, and is not particularly limited herein.
In the embodiment of the invention, after the server receives the indication signal which is sent by the application program arranged in the client and used for indicating the start of the mine wind-electricity blocking experiment, the server can acquire the video data of the current wind cone shape of the local ventilator by triggering the preset video acquisition equipment. The video acquisition equipment can be video acquisition equipment such as a video camera, video monitoring equipment or a video recorder.
As shown in fig. 5, the video capture device 504 may be generally disposed at the intersection of the excavation roadway and the air intake roadway of the mine, so as to facilitate the simultaneous acquisition of the wind-barrel-shaped video data of the local ventilator and the video data of the running state of the belt conveyor, thereby enabling the server to simultaneously acquire the wind-barrel-shaped video data of the local ventilator through the disposed video capture device.
Similarly, the setting position of the video capture device in the present invention is not limited to the above-mentioned situation, and only needs to be satisfied that the audio data generated by the local ventilator can be accurately obtained, which is not described in detail herein.
It should be noted that, in an actual application scenario, the ventilation ducts of the air duct of the local ventilator are all made of soft materials, and therefore, the shapes of the ventilation ducts of the air duct may also change correspondingly according to the difference of the air volume. When the local ventilator is in a low-speed running state or a stop running state, the ventilation duct of the air duct is usually in a dry-shrivelled state, and when the local ventilator is in a high-speed or normal running state, the ventilation duct of the air duct is usually in a full state. The shape change characteristics of the air duct and the ventilation duct of the air duct can be identified through an image identification technology, so that the current running state of the local ventilator can be known.
And the local ventilator operation state monitoring unit 202 is used for determining the operation state of the local ventilator according to the audio data and the video data of the air duct shape.
In the embodiment of the present invention, the determining of the operation state of the local ventilator according to the audio data at the air outlet of the air duct and the video data of the shape of the air duct may be specifically implemented in the following manner:
a. firstly, a server can detect an audio decibel value corresponding to the audio data through an audio decibel measurement module, and extract the wind tube shape feature information in the wind tube shape video data by using a feature extraction algorithm. Then, the server may pre-construct an index combination including the audio decibel value and the air duct shape characteristic information, construct a first corresponding relationship between the audio decibel value, the air duct shape characteristic information, and an operation state of the local ventilator, and determine the operation state of the local ventilator corresponding to the index combination by using the index combination and the first corresponding relationship.
b. Firstly, a server can obtain an audio decibel value corresponding to the audio data through an audio decibel measurement module, compare the audio decibel value with a standard audio decibel value of an air duct air outlet of the local ventilator, and generate a corresponding first target parameter value for identifying the audio decibel value according to a comparison result. And judging whether a preset local ventilator air duct shape monitoring model is triggered to monitor the current air duct shape in the air duct shape video data or not according to the first target parameter value. Further, the characteristic information of the shape of the current air duct corresponding to the shape of the current air duct is obtained. Constructing a second corresponding relation between the air duct shape characteristic information and the running state of the local ventilator; and determining the running state of the local ventilator according to the current air duct shape characteristic information and the second corresponding relation.
In the specific implementation process, a local ventilator noise identification model, a local ventilator wind cylinder shape monitoring model and a belt conveyor belt running state monitoring model are preset in the server. The server can compare the audio decibel value with a standard audio decibel value of an air duct air outlet of the local ventilator through a local ventilator noise identification model, and generate a corresponding first target parameter value according to a comparison result.
For example: the standard audio decibel value of the air duct air outlet of the local ventilator can comprise: when the local ventilator is in a stop running state, the standard audio decibel value T1(T1 is less than or equal to 5dB) of the air outlet of the air duct; when the local ventilator is in a low-speed running state, the standard audio decibel value of the air outlet of the air duct is T2 (T2 is more than or equal to 5dB and less than or equal to 20 dB); and when the local ventilator is in a normal or high-speed running state, the standard audio decibel value of the air outlet of the air duct is T3 (T3 is more than or equal to 60dB and less than or equal to 85 dB). When the server identifies that the audio decibel value generated by the local ventilator is T4 through the local ventilator noise identification model, a corresponding first target parameter value is generated to be 1 when T4 is less than or equal to 5dB or 5dB is less than or equal to T4 is less than or equal to 20dB, and when the server identifies that the audio decibel value generated by the local ventilator is 60dB or less than or equal to T4 or less than or equal to 85dB through the local ventilator noise identification model, a corresponding first target parameter value is generated to be 0.
According to the first target parameter value, whether a preset local ventilator air duct shape monitoring model is triggered to extract air duct shape feature information in the air duct-shaped video data is judged, and the method specifically comprises the following steps:
when the first target parameter value is 1, triggering a preset local ventilator air duct shape monitoring model to extract air duct shape characteristic information in the air duct shape video data; and when the first target parameter value is 0, not triggering a preset local ventilator wind cylinder shape monitoring model to extract wind cylinder shape characteristic information in the wind cylinder shape video data. The local ventilator wind tube shape monitoring model is used for monitoring characteristic information of wind tube shape change conditions in the uploaded video data. And if the local ventilator air duct shape monitoring model monitors that the shape of the air duct is changed from full to flat, generating a second target parameter value to be 1, otherwise, generating a second target parameter value to be 0.
In an actual implementation process, a specific implementation time and a specific operation flow are usually set for a wind power blocking experiment, so that in order to improve the processing efficiency of audio data and video data and reduce the workload of image recognition, a time factor can be further considered when extracting the audio data acquired by the audio acquisition device and the video data acquired by the video acquisition device. Namely: extracting an audio data segment in a target time interval from the audio data, and identifying an audio decibel value contained in the audio data segment; extracting a video data segment in a target time interval from the video data with the air duct shape, decoding the video data segment into a corresponding video frame, and identifying air duct shape characteristics contained in the video frame based on an image characteristic identification algorithm; and determining the running state of the local ventilator according to the audio decibel value and the shape characteristic of the air duct.
A first video data obtaining unit 203, configured to obtain video data of a current operation state of the belt conveyor when the operation state meets a preset operation state condition.
In the embodiment of the present invention, when the operating state meets the preset operating state condition, the video data of the current operating state of the belt conveyor may be obtained through the preset video capture device, which specifically includes the following two conditions:
in the first case, when the operating state of the local ventilator satisfies the stop operating state condition, the video data of the current operating state of the belt conveyor acquired by the video acquisition device can be further obtained. In another case, when the operating state of the local ventilator satisfies the low-speed operating state condition, the video data of the current operating state of the belt conveyor acquired by the video acquisition device can be obtained, so as to perform the next analysis processing process. The low-speed running state refers to a running state of the local ventilator corresponding to the condition that the wind speed of the wind drum air outlet of the local ventilator is lower than a preset wind speed threshold value.
For example: when it is detected that the decibel value T of the audio generated by the operation state of the local ventilator is less than 5dB, it may be determined that the operation state of the local ventilator satisfies the stop operation state condition. When it is detected that the operating state of the local fan generates an audio decibel value T between 5dB and 20dB, it can be determined that the operating state of the local fan satisfies the low-speed operating state condition.
And the belt conveyor current running state monitoring unit 204 is used for judging whether a power supply of the belt conveyor is in a power-off state currently according to the video data of the belt conveyor current running state, and if so, judging that the wind power blocking experiment is finished.
In an embodiment of the present invention, the determining whether a power supply of the belt conveyor is currently in a power-off state according to the video data of the current running state of the belt conveyor specifically includes: generating a corresponding second target parameter value according to the running state of the local ventilator; triggering a preset belt conveyor monitoring model to extract running state characteristic information in the video data of the current running state of the belt conveyor according to the second target parameter value; and judging whether the current running state of the belt conveyor is a stopped running state or not according to the running state characteristic information, if so, judging that a power supply of the belt conveyor is in a power-off state, and if not, judging that the power supply of the belt conveyor is in a power-on state.
According to the second target parameter value, triggering a preset belt conveyor monitoring model to extract the running state characteristic information in the video data of the current running state of the belt conveyor, and specifically comprising the following steps:
when the second target parameter value is 0, the preset belt conveyor monitoring model is not triggered to extract the running state characteristic information in the video data of the current running state of the belt conveyor. The belt conveyor monitoring model is used for monitoring running state characteristic information of the belt conveyor in the uploaded video data. And if the belt conveyor monitoring model monitors that the conveying state is changed from running to stopping, generating a third target parameter value to be 1, otherwise, generating a third target parameter value to be 0. Wherein: and generating a third target parameter value of 1 to represent that the wind power blocking test is completed, and generating a third target parameter value of 0 to represent that the wind power blocking test is not completed. If the wind power locking test in the mine is judged not to be completed, the server can generate corresponding alarm indication information, and sends the alarm indication information to the authenticated mobile terminal equipment through a preset communication device, so that maintenance management personnel are informed in time, and the field fault analysis and treatment are facilitated for the maintenance management personnel.
In the actual implementation process, when the power supply of the belt conveyor is judged to be in the power-off state currently, a first record log used for indicating that the wind power blocking experiment is completed can be generated; when the power supply of the belt conveyor is judged to be in the electrified state currently, a second recorded log used for indicating that the wind power blocking experiment is not completed can be generated, the first recorded log and the second recorded log are stored in a data storage system in a server, and visual display can be carried out through a touch display screen on equipment, so that maintenance and management personnel can conveniently check the logs subsequently.
It should be noted that the wind power locking described in the present invention means that after the local ventilator which normally works stops operating or when the wind speed in the wind drum is lower than a specified value, the local ventilator can automatically trigger to cut off the power supply of the non-intrinsically safe electrical equipment in the wind supply area, and when the local ventilator recovers normal ventilation or the wind speed in the wind drum is higher than the specified value, the power supply of the non-intrinsically safe electrical equipment can normally supply power to operate. Therefore, the power supply of the non-intrinsic safety electrical equipment in the wind stop area can be automatically cut off after the local ventilator which normally works stops running or stops wind. The explosion caused by interaction of the gas concentration rise in the tunnel and the electrified power supply equipment after the local ventilator stops running or when the wind speed in the wind barrel is lower than a specified value is effectively avoided.
