In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
It should be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
Furthermore, the terms "first," "second," "third," and the like in the description of the present specification and in the appended claims, are used for distinguishing between descriptions and not necessarily for indicating or implying a relative importance.
The method for controlling the air door in the mine provided by the embodiment of the application can be applied to terminal equipment such as tablet computers, notebook computers, ultra-mobile personal computer (UMPC) and netbooks, and the specific type of the terminal equipment is not limited.
Referring to fig. 1, fig. 1 shows a flowchart of an implementation of a method for controlling a damper in a mine according to an embodiment of the present application, where the method includes the following steps:
s101, the terminal equipment acquires an image through a camera device arranged on an air door to obtain an image to be identified; the image to be identified at least comprises a target object.
In one embodiment, the damper is an important structure for ventilation of the mine, and can block the air flow, so that conditions are created for distribution of the air flow of the mine as required, and convenience is provided for pedestrians and transportation. The above-mentioned image pickup apparatus is an apparatus for image acquisition of an environment in front of a damper, which can be used for acquiring pedestrians or vehicles that need to pass through the damper. I.e. the target object includes but is not limited to a pedestrian, a transport vehicle or other traffic equipment.
It can be understood that the image capturing device can acquire images at any time to obtain images to be identified; image acquisition may also be performed based on a control signal of the terminal device, which is not limited. However, when one or more target objects are included in the acquired image to be identified, the terminal device may perform the in-mine damper control method described above.
S102, the terminal equipment determines the target category of the target object.
In one embodiment, S101 above has illustrated that the target object includes, but is not limited to, a pedestrian, a transport vehicle, or other traffic equipment. Thus, the target class of the target object may correspond to a pedestrian class, a carrier class, or other traffic device class. It can be appreciated that the terminal device may store a trained image recognition model in advance, for recognizing the acquired image to be recognized, so as to determine each target object in the image to be recognized and a target class corresponding to each target object.
In one embodiment, the image recognition model refers to a model that uses a computer to process, analyze and understand images to recognize target objects of various target classes. The image recognition model comprises the processing procedures of image acquisition, preprocessing, feature processing, classification decision and the like. Since the image recognition model is an existing mature model, this will not be described.
S103, the terminal equipment opens the air door at an opening speed corresponding to the target class.
In one embodiment, the speeds of the different target object dampers are not generally uniform. For pedestrians and transport vehicles, for example, the walking speed of a pedestrian is generally much less than the travelling speed at the transport. Therefore, the air door can be opened at different opening speeds for different target categories, so that the terminal equipment can open the air door at reasonable opening speeds according to the actual speed of the transport vehicle or the pedestrian in the mine. Furthermore, the air door can be completely opened before the transportation vehicle or the pedestrian in the mine reaches the air door, and the damage of the door body caused by the too high running speed of the door leaf in the opening process is also ensured.
It can be understood that S101 is to acquire an image to be identified by using an image capturing device. Therefore, it can be considered that the image pickup apparatus can photograph the target object from a long distance to recognize the target object required to make a pass in advance. Therefore, the air door is opened at a reasonable opening speed, so that the transportation vehicle or pedestrian in the mine can be completely opened before reaching the air door.
In an embodiment, the staff may pre-establish the association relationship between the multiple target categories and the corresponding opening speeds, and store the association relationship in the terminal device.
S104, after the terminal equipment confirms that the target object passes through the air door, the air door is closed at a preset closing speed.
In an embodiment, the manner of the terminal device confirming that the target object passes through the damper may be: when the terminal equipment identifies the image to be identified, which is acquired by the camera equipment in front of the air door, a target object is not identified; alternatively, a photo sensor is installed behind the damper, and the photo sensor is used for confirming whether the target object has passed through the damper, and then the photo sensor can transmit the sensing result (the result of confirming that the target object has passed through the damper) to the terminal device.
In an embodiment, the preset closing speed may be set by a worker in advance according to actual situations. It will be appreciated that the damper may be closed with a suitable closing speed because the target object has passed through the damper. Therefore, the terminal equipment can ensure that the door body is not damaged due to the fact that the running speed of the door leaf is too high in the closing process of the air door.
In an embodiment, after confirming that the target object passes through the air door, the terminal device may delay a preset time period, and then close the air door at a preset closing speed, so as to avoid a fault of the terminal device, and erroneously confirm that the target object passes through the air door, and close the air door in advance. The preset duration may be set by a worker according to actual situations, which is not limited.
In an embodiment, a voice alarm may be further installed on the air door, and in the process of opening the air door, the terminal device may control the voice alarm to send out a prompt voice to prompt the target object to pass through the air door. And then closing the prompt voice after the terminal equipment determines that the target object passes through the air door.
In the embodiment, the terminal device collects an image to be recognized including a target object through an imaging device installed on a damper; and then, carrying out recognition processing on the image to be recognized to determine the target category to which the target object belongs. And then, determining the opening speed of the air door when the air door is currently opened based on the target type so as to ensure that the target object in the mine can be completely opened before reaching the air door, and ensuring that the door body is not damaged due to the too high running speed of the door leaf in the opening process. Finally, after the target object is confirmed to pass through the air door, the air door is closed at a fixed closing speed, so that the air door is further ensured not to be damaged due to the fact that the running speed of the door leaf is too high in the closing process.
Referring to FIG. 2, in one embodiment, at least two sets of photosensitive sensors are mounted on the damper; at least two sets of photosensitive sensors are respectively arranged at the front side and the rear side of the air door; in the step S101 of acquiring an image by an image capturing apparatus mounted on a damper, the method specifically includes the following substeps S1011-S1013, which are described in detail below:
s1011, the terminal equipment obtains a first sensing result when at least two sets of photosensitive sensors work.
In one embodiment, the photosensitive sensor can be further used to confirm whether the target object is located in front of the damper for the target object on either side of the damper. The first sensing result is a sensing result of the target object in front of the air door.
Specifically, any one set of photosensitive sensor respectively comprises an infrared emission end and an infrared receiving end, and is respectively arranged on the left side and the right side of the air door. The optical signal emitted by the infrared emitting end can be received by the infrared receiving end at the beginning. And if the target object needs to pass through the air door, the target object shields the light signal emitted by the infrared emission end of the air door, so that the light signal received by the infrared receiving end at the moment is changed. And then, the infrared receiving end amplifies and converts the changed optical signals to obtain electric signals. Finally, the electrical signal is transmitted to the terminal device. Based on the acquired electric signals, the terminal equipment determines that the first sensing result of the current photosensitive sensor is the sensing result of the target object in front of the air door. It can be understood that if the optical signal is not blocked by the target object, the optical signal at the infrared receiving end should not be changed, that is, the subsequent step of generating an electrical signal and transmitting the electrical signal to the terminal device is not performed.
S1012, the terminal equipment determines a first photosensitive sensor for shielding the emitted ray according to the first sensing result.
S1013, the terminal equipment controls the image pickup equipment on the same side with the first photosensitive sensor to collect images, and an image to be identified is obtained.
In one embodiment, determining that the emitted ray is blocked is that the light signal emitted from the photosensitive sensor in S1011 is blocked. At this time, the blocked photosensitive sensor is the first photosensitive sensor.
In one embodiment, the above S1011 has been described as having at least two sets of photosensitive sensors mounted on the front side and rear side of the damper, respectively. Based on this, upon receiving the first sensing result, the terminal device may further determine the first photosensor generating the first sensing result to determine which side (front side or rear side) of the damper has the target object to be passed.
In one embodiment, it is understood that both the front and rear sides of the damper may have a target object for passage. Therefore, a worker may set the image pickup device and the photo sensor in advance at both the front side and the rear side of the damper, respectively, to monitor whether the target object needs to enter the mine or leave the mine.
For example, based on the description of the photosensitive sensor in S1011, the staff may preset the unique identification information of each set of photosensitive sensors, and may set that the infrared receiving end of the photosensitive sensor should also transmit the corresponding unique identification information when transmitting the electrical signal. At this time, the terminal device may store in advance a front side or a rear side of the damper where the photosensitive sensor corresponding to each unique identification information is located, and a front side or a rear side of the damper where each image pickup device mounted on the damper is located. And then, controlling the image pickup equipment on the same side as the first photosensitive sensor to collect images to obtain images to be recognized so as to reduce the working time of the image pickup equipment.
Referring to fig. 3, in an embodiment, the kinds of target objects include a plurality of kinds; the determining the target category of the target object in S102 specifically includes the following substeps S1021-S1022, which are described in detail below:
s1021, the terminal equipment determines the priority of each target object included in the image to be identified based on the corresponding relation between the preset multiple target objects and the priority.
S1022, the terminal equipment determines the category corresponding to the target object with the highest priority as the target category of the target object.
In one embodiment, the target objects described in S101 may be plural, and the speeds of the passing doors of the different target objects described in S103 are not generally uniform. Based on the above, if the image to be identified includes multiple target objects at the same time, in order to unify the opening speed of the air door and not affect the passing speed of the target objects, the terminal device may determine the target object with the highest priority from the multiple target objects. And then, determining the category corresponding to the target object with the highest priority as the target category of the plurality of target objects. Finally, the terminal device can use the opening speed of the category corresponding to the target object with the highest priority to open the air door, so as to ensure that the air door is completely opened when the target object with the highest priority reaches the front of the air door, and the target object does not need to wait in front of the air door.
In an embodiment, generally, for multiple target objects, in order not to affect the passing of each target object, the terminal device may set a corresponding priority based on the passing speed of each target object. Specifically, the terminal device may set the priority of the target object with the highest passing speed as the highest priority, and sequentially set the corresponding priority according to the passing speed preset by the staff for each target object.
It should be noted that any one set of photosensitive sensors may be disposed at two sides of the preset distance from the damper, so that the terminal device may determine in advance that the target object needs to pass through the damper, and further execute the steps S101 to S104 described above. The preset distance may be set by a worker in advance according to actual situations, which will not be described in detail.
Referring to FIG. 4, in one embodiment, there are two dampers in any one of the lanes in the mine; before the damper is opened at the opening speed corresponding to the target category in S103, the following steps S131 to S133 are further included, which are described in detail as follows:
s131, aiming at any one air door to be opened currently, the terminal equipment determines the working state of the other air door, wherein the working state comprises an opening state and a closing state.
In an embodiment, the passing roadway is a roadway for a target object to enter and exit the mine. Wherein, for any one passage roadway, two air doors are usually arranged. The above S101 has described that the damper is an important structure for ventilating the mine, which can block the flow of air. Therefore, if there is only one air door for one roadway, each time the air door is opened, the air flow in the mine, which should originally travel along a prescribed route, does not travel along the original route (flows out from the air door), and no air (no fresh air) exists in the underground partial area.
In an embodiment, after the current damper to be opened is the damper that has been executed in the steps S101 to S102, the terminal device determines that the damper needs to be opened correspondingly.
And S132, if the working state of the other air door is a closed state, the terminal equipment opens the air door to be opened.
And S133, if the working state of the other air door is an opening state, stopping opening the air door to be opened by the terminal equipment until the working state of the other air door is a closing state.
In one embodiment, for two dampers of a roadway, to avoid simultaneous opening of the two dampers, the wind flow in the mine that would otherwise be routed is affected. At this time, the terminal equipment needs to acquire the working state of another air door in the same tunnel for the air door to be opened currently. If the working state of the other air door is the closed state, the terminal device may directly execute the steps of S103-S104. That is, after the current air door to be opened is opened, the other air door is in a closed state, so that the air flow cannot flow out of the roadway or can walk according to a specified route. If the working state of the other air door is the opening state, the terminal equipment needs to stop opening the air door to be opened currently until the working state of the other air door is the closing state, and then the steps of S103-S104 are executed.
In an embodiment, the control method of the other damper should also be consistent with the control method of the damper to be opened currently, which will not be described in detail.
Referring to fig. 5, in one embodiment, after the damper is opened at the opening speed corresponding to the target category in S103, the following steps S134-S135 are further included, which are described in detail below:
s134, the terminal equipment acquires a plurality of second sensing results when a second photosensitive sensor which is positioned on a different side from the first photosensitive sensor works.
In an embodiment, the above S1013 is explained for the first photosensitive sensor, which will not be described. It will be appreciated that for the photo sensor on the front side of the door and the photo sensor on the rear side of the door of a damper, where the photo sensor on the front side or the rear side of the door is determined to be the first photo sensor, the photo sensor on the other side of the damper should be determined to be the second photo sensor. That is, "first", "second" in the above-described "first photosensitive sensor" and "second photosensitive sensor" are used only for distinguishing descriptions.
S135, if the plurality of second sensing results comprise a first result that the ray emitted by the second photosensitive sensor is not blocked and a second result that the ray emitted by the second photosensitive sensor is blocked, and the acquisition time of at least one first result is later than the acquisition time of the second result, the terminal equipment confirms that the target object passes through the air door.
In one embodiment, any one of the photosensors is operated in real time, so that the second photosensor will produce a plurality of second sensing results when operated. Based on the explanation of the photosensitive sensor in S1011, the plurality of second sensing results may be considered to include, but are not limited to, a first result that the optical signal emitted from the infrared emitting end of the second photosensitive sensor is received by the infrared receiving end (the radiation emitted from the second photosensitive sensor is not blocked), and a second result that the optical signal emitted from the infrared emitting end of the second photosensitive sensor is not received by the infrared receiving end (the radiation emitted from the second photosensitive sensor is blocked).
In an embodiment, under normal conditions, if the damper does not pass through the target object, the sensing result of the second photosensitive sensor will always be the first result that the optical signal emitted by the infrared emitting end is received by the infrared receiving end. Then, when the target object passes through the air door, a second result that the optical signal emitted by the infrared emission end is not received by the infrared receiving end exists in the second photosensitive sensor. Finally, after the target object passes through the air door, the sensing result of the second photosensitive sensor is recovered to be the first result that the optical signal emitted by the infrared emission end is received by the infrared receiving end.
Based on the above, it can be determined that when the terminal device acquires the two sensing results uploaded by the second sensor, if there is at least one first result with a time later than that of the second result, it can be determined that the target object has passed through the damper.
In this embodiment, a set of photosensitive sensors is respectively disposed on the front side and the rear side of the air door, so as to automatically determine whether the target object passes through the air door, thereby realizing intelligent control of the air door.
Referring to FIG. 6, in one embodiment, a magnetometric sensor is also mounted on the damper; after the damper is opened at the opening speed corresponding to the target category in S104, the following steps S141-S142 are further included, as follows:
s141, the terminal equipment determines whether a magnetic force detection sensor detects a preset magnetic force object.
S142, if the magnetic force detection sensor detects a preset magnetic force object, the terminal equipment stops the operation of the air door.
In an embodiment, the magnetic force detection sensor can utilize an electromagnetic working principle to convert non-electric quantity or electromagnetic quantity into corresponding electric signals through the change of the position relation between magnetic force detection and a preset magnetic force object, so that the purpose of controlling or measuring the distance between the preset magnetic force object and the magnetic force detection sensor is achieved.
Based on this, the terminal device may provide a magnetic force detection sensor on the damper, and set a preset magnetic force object at a position near the magnetic force detection sensor when the damper is closed. In this way, the terminal device may determine whether the damper has been closed according to the detection result of the magnetic force detection sensor (the magnetic force detection sensor detects a preset magnetic force object, or the distance between the magnetic force detection sensor and the preset magnetic force object is detected to be smaller than a preset value). The preset value may be set by a worker according to actual situations, and is not limited thereto.
In one embodiment, the predetermined magnetic force object includes, but is not limited to, an object containing any one of iron, cobalt, nickel, etc., which is not limited thereto.
In one embodiment, each damper may be provided in the form of two door bodies. Therefore, the worker can set a magnetic force detection sensor in one door body in advance, and set a magnetic force object in the other door body at a corresponding position. Then, when the two doors are closed, the distance between the magnetic force detection sensor and the magnetic force object is smaller than a preset value; and when the two door bodies are opened, the distance between the magnetic force detection sensor and the magnetic force object is larger than a preset value.
In an embodiment, if the magnetic force detection sensor detects a preset magnetic force object, the magnetic force detection sensor should upload the detection result to the terminal device, and then the terminal device stops the operation of the air door.
In this embodiment, a preset magnetic force object is installed at a position where the magnetic force detection sensor can detect the magnetic force object when the damper is closed by installing the magnetic force detection sensor on the damper. Further, the terminal device can be enabled to judge when the air door should stop running so as to avoid damage to the air door and other safety accidents caused by the fact that the terminal device forces the air door to continue running after the air door is closed.
