Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Embodiment one:
Referring to fig. 1, a flowchart of a method for controlling a coal mine park according to an embodiment of the present invention is shown. Specifically, the invention provides a control method for a coal mine park, which comprises a control area and a construction area; the construction area consists of a plurality of mutually communicated operation roadways, and a camera device connected with the control area is arranged in the operation roadways; the control method comprises the following steps:
step S1, transmitting the corresponding operation picture information in the operation tunnel to a control terminal in a management and control area by the camera device;
Step S2, identifying first equipment information in the operation picture information and a first sequence number of an operation roadway, and judging whether the first equipment information and the first sequence number are matched with a first preset information group in a database;
Step S3, if not, establishing communication connection between the control terminal and a communication module arranged in the first operation roadway, and sending a first communication instruction to the first operation roadway; the first operation roadway is an operation roadway with first equipment information and first sequence numbers not matched with a first preset information group;
Step S4, if the operation picture information in the first operation tunnel is not adjusted from the first equipment information to the second equipment information matched with the first sequence number in the first preset time, judging that the execution of the first communication instruction fails, and increasing the marking times of the first operation tunnel at the control terminal;
And S5, improving the monitoring priority of the first operation roadway in a future time period according to the marking times.
In combination with the actual situation of the coal mine park, a plurality of operation roadways often exist in the coal mine park, and the specific actions of different operation roadways are different. For example, a heading machine is arranged in an operation tunnel to dig ores, and some operation tunnels are used as communication centers for placing a large number of computers and the like. Thus, for the constructors working in different working tunnels, the requirement of wearing corresponding working equipment is provided, and it can be understood that different working equipment is matched with corresponding working environments, for example, in the working tunnels provided with tunneling equipment, the constructors are required to wear corresponding dustproof equipment, such as dustproof masks, and wearing safety helmets, so that broken stone particles are prevented from directly hitting the heads of the constructors in the process of mining ores, and the risk caused by improper wearing of the working equipment in the construction process is reduced.
Further, the procedure regarding whether or not the wearing of the supervising constructor is normal is often performed before entering the working tunnel, and the conventional supervising means is limited to the oral delivery of the safety normative person. And when constructors enter the operation tunnel, effective supervision effect is difficult to maintain. Specifically, in an actual working roadway, a constructor is often influenced by the working environment of the working roadway, for example, in the working roadway provided with the tunneling equipment, a great amount of heat is generated in the working process of the tunneling equipment, so that the temperature of the working environment is increased, and the constructor often removes a safety helmet or a dust mask, for example, so that the safety risk of working in the working roadway is increased, for example, suspended dust is absorbed by people unhindered, and health hazards are caused.
Furthermore, because a certain intersection exists on the operation content in each operation roadway, the condition that the corresponding constructor moves back and forth in different operation roadways can occur, and if the constructor does not replace matched equipment in time before entering different operation roadways by combining the analysis, the above-mentioned potential safety hazard is easily caused.
Therefore, in summary, it is necessary to follow the equipment wearing condition of the constructors in the working tunnel in time. Then, in combination with the technical scheme, the image pickup device is utilized to capture the operation scene in the operation roadway to form operation picture information, and the control terminal is utilized to be in communication connection with the image pickup device so as to transmit the operation picture information to the control terminal, so that the operation picture information is subjected to characteristic analysis, and whether the first equipment information is matched with the first sequence number or not is further identified.
Further, the first association information set formed by the first equipment information and the first sequence number is compared with the first preset information set to determine whether the first association information set and the first preset information set can be successfully matched, if the first association information set and the first sequence number are successfully matched, the first equipment information and the first sequence number are matched, for example, at this time, the first equipment information is, for example, a dust mask and/or a safety helmet which are worn by the constructor and are matched with the tunnelling equipment, and the first sequence number is a corresponding operation roadway provided with the tunnelling equipment, so that the operation roadway provided with the tunnelling equipment can be defined as the tunnelling roadway for convenience of understanding.
On the contrary, if the first association information set is not matched with the first preset information set, the control terminal sends a first communication instruction to the communication module in the first operation roadway, specifically, the first communication instruction may be in a voice broadcasting mode, so as to alert constructors in the first operation roadway to correct wearing equipment in time at the moment, for example, from the first equipment information to the second equipment information matched with the first sequence number. The setting of the first preset time is used for preparing time required by constructors for replacing equipment. If the first equipment information still exists in the operation picture information intercepted by the image pickup device after the first preset time is exceeded, the failure of executing the first communication instruction is judged, and then the monitoring priority of the first operation roadway is improved.
The above-mentioned monitoring priority may be understood as that the number of times of the job screen information transmitted to the first job lane is greater than the remaining plurality of job lanes in the same time.
Therefore, in the technical scheme, by establishing communication between the image capturing device and the control terminal, or by understanding that a network transmission relationship is formed between the image capturing device and the control terminal, effective supervision on actual operation conditions in each operation roadway can be realized, and of course, the control terminal can process operation picture information of the image capturing device more in real time, so that operation picture information in the operation roadway can be timely controlled, or the image capturing device is transmitted to the operation picture information of the control terminal in a spaced transmission mode, rather than the continuous transmission mode, and the method is not limited. Furthermore, the first operation roadway is monitored again through secondary transmission of operation picture information, namely after the first communication instruction is sent, the effect of information feedback is achieved, and the situation that the latest operation condition in the first operation roadway cannot be accurately obtained after the first communication instruction is sent is avoided.
Furthermore, the first operation roadway can be marked according to the result of information feedback, and the monitoring priority of the first operation roadway in the first future time period can be adjusted according to the marking times, so that the monitoring condition of the first operation roadway is effectively maintained, and the normal wearing equipment of constructors working in the first operation roadway can be positively supervised by associating the marking times with the monitoring priority. Namely, by distinguishing the monitoring strength of the first operation roadway and the monitoring strength of the rest operation roadways, the monitoring of the first operation roadway is emphasized, and the effect of guiding standard wearing is achieved to a certain extent.
Preferably, the image pickup device arranged in the operation tunnel is defined as a first image pickup device, and the image pickup device arranged in the first operation tunnel is defined as a second image pickup device; increasing monitoring priority of the first operation roadway in a future time period according to the marking times, comprising: controlling the time interval of the second camera device for transmitting the operation picture information in the first operation tunnel to be smaller than the time interval of the first camera device for transmitting the operation picture information in the operation tunnel; and/or controlling the monitoring priority of the first operation roadways in the future time period to be associated with the corresponding marking times; the monitoring priority of the first operation tunnel with more marking times is higher, and when the first communication instruction in the first operation tunnel is judged to be successfully executed, the corresponding marking times are reduced.
Specifically, the number of marks corresponding to each first operation lane is dynamically changed, and is specifically related to the number of times that the first communication instruction is judged to be failed or successful in the process that the first operation lane is monitored. For example, if the first communication command is judged to be executed successfully, the number of marking times is increased, and if the first communication command is judged to be executed successfully, the number of marking times is reduced. Thus, when the number of marking is greater, it means that the monitoring priority of the first operation lane is higher, the first operation lane is preferably monitored compared with other operation lanes, and a specific monitoring mode includes, for example, increasing the monitoring frequency, which is shown by a greater number of times of sending operation screen information to the control terminal in the same time.
Further, when there are a plurality of first job lanes defined in the construction area, the number of marks in the plurality of first job lanes is greater, and the corresponding monitoring priority is higher, it should be noted that the monitoring priority for any one of the plurality of first job lanes is higher than the monitoring priority for any one of the plurality of job lanes. Of course, if the number of marks corresponding to the first operation lane is one time and the first communication command is determined to be successful in the next monitoring period, the number of marks is reduced to zero, and then the first operation lane is redefined as the operation lane at the control terminal, so that the first operation lane is consistent with the monitoring priority of the other operation lanes.
Preferably, the operation roadway comprises a central area, a middle area and a peripheral area which are communicated with each other, the central area corresponds to the position of the tunneling equipment, the peripheral area is communicated with the rest operation roadways, and the middle area is formed between the central area and the peripheral area; transmitting the operation picture information in the corresponding operation tunnel to the control terminal in the control area by the image pickup device, comprising: intercepting first characteristic information of a first current image corresponding to a central area in the operation picture information, and comparing the first characteristic information with pre-stored characteristic information of a pre-stored image to obtain a first comparison result; judging whether a preset dust spreading trend in the central area meets the early warning requirement according to the first comparison result; if yes, a first early warning signal is sent out through early warning equipment arranged in the operation roadway; after the first early warning signal is maintained for a first preset time, intercepting second characteristic information of a second current image in the operation roadway by the camera device, and judging whether the second characteristic information meets preset standard requirements or not; if the preset standard requirement is judged to be met, controlling the spraying equipment arranged in the operation tunnel to execute spraying action on at least the central area in the operation tunnel; wherein the first characteristic information includes a coverage ratio of the suspended dust in the central region; the second characteristic information comprises characteristic information corresponding to the standard wearing of the safety harness by the operator.
In a specific example, when the working roadway is used as a tunneling roadway, a large amount of suspended dust is often generated around the tunneling equipment in the process of excavating ore, and once the suspended dust concentration reaches the dust explosion concentration, the explosion is easily generated under the ignition of a fire source generated in the process of excavating ore by the tunneling equipment. Therefore, in order to avoid the occurrence of the situation in time, in the present technical solution, by comparing the first characteristic information in the first current image with the pre-stored characteristic information, it can be understood that the first characteristic information is the characteristic information corresponding to the suspended dust situation, and the pre-stored image is any one of the plurality of images corresponding to the suspended dust situation stored in the history database and having different levels of early warning requirements.
It can be understood that the plurality of pre-stored images stored in the historical database are images of suspended dust captured in a dynamic environment successively, so that the suspended dust condition in the operation roadway at the current time can be obtained according to the first comparison result and compared with the plurality of suspended dust conditions in the historical database in a continuous time period, so as to obtain the spreading trend of the suspended dust in the operation roadway at the next time, for example, when the spreading trend meets the early warning requirement, the control early warning device sends out the first early warning signal.
Further, the first warning signal may be embodied as an alarm whistle, and the second characteristic information in the second current image obtained after the first preset time specifically includes the operation position and the equipment wearing information in the operation tunnel where the constructor is located. It will be appreciated that the suspended dust is generated from the central region and then spreads sequentially to the central and peripheral regions. And the preset specification requirements are requirements of the coal mine industry relating to standard wearing of construction equipment. Therefore, after judging that the requirement of the preset standard is met, the spraying equipment can be controlled to perform spraying action on at least the central area, so that the purpose of reducing the concentration of suspended dust is achieved, and the risk of dust explosion is effectively avoided.
Preferably, capturing, by the image capturing device, second feature information of a second current image in the operation roadway, and determining whether the second feature information meets a preset specification requirement, includes: if not, searching first identity information which is not matched with the preset specification requirement in the second current image through the twin neural network; a dust avoidance signal is sent to receiving equipment of a target object corresponding to the first identity information through a control terminal; if the receiving equipment sends a feedback signal to the control terminal within the second preset time, and the dust avoidance signal is judged to be sent successfully, the spraying equipment is controlled to sequentially execute spraying actions to the central area, the middle area and the peripheral area; if the receiving equipment does not send a feedback signal to the control terminal within the second preset time, the tunneling equipment is controlled to stop running, and then the spraying equipment is controlled to execute spraying action into the operation tunnel.
Specifically, in combination with the above, when second characteristic information which does not meet the requirement of the preset specification appears in the operation roadway, before the spraying equipment is controlled to execute the spraying action, the constructor which does not meet the requirement of the preset specification needs to be prevented from being wetted, and then the constructor needs to be dissuaded to be out of the set spraying range of the spraying equipment in time, namely, the construction equipment is realized in a mode of sending a dust avoidance signal to the construction equipment as in the technical scheme. Further, in order to ensure that the constructor is out of the set spraying range, the feedback signal sent by the receiving device of the subsequent constructor can be confirmed, and further, the dust avoidance signal can be judged to be sent successfully, so that the spraying device can be controlled to smoothly execute the spraying action. Otherwise, the running of the tunneling equipment is stopped, the purpose of avoiding continuous generation of suspended dust is achieved, the spraying equipment is controlled to execute spraying action, the speed and the range of the spread of the suspended dust are reduced to a certain extent, correspondingly, the spraying range of the spraying equipment when the spraying action is executed is correspondingly reduced, and further the influence on constructors in an operation roadway is reduced.
On the basis of the above, an indication device is arranged on the upper inner wall of the tunneling roadway, the indication device is controlled by a control terminal, and corresponding indication lamp signals of relevant indication are transmitted to the central area, the middle area and the peripheral area in the tunneling roadway according to relevant instructions of the control terminal, for example, when the spraying range of the spraying equipment covers the central area, the indication device is controlled to transmit a red warning lamp which covers the central area, so that a warning effect on constructors positioned in the central area is achieved, the constructors are reminded to be far away from the central area, and meanwhile, the indication device transmits a green warning lamp to the middle area and/or the peripheral area, for example, so that the constructors can be reminded to move into the area covered by the green warning lamp, the situation that the constructors fall into the spraying range is avoided, the man-machine interaction effect is improved, and the construction safety of the constructors is guaranteed.
In addition, it can be understood that the tunneling roadway is in a dynamic environment for continuously mining ores, so that the condition of the inner wall of the tunneling roadway needs to be monitored in real time, and safety accidents caused by damage of the inner wall are avoided.
Further, inflammable and explosive gases such as gas are often adsorbed onto ores, and more gases such as gas are transferred from a buried closed environment to a construction environment exposed in a tunneling roadway along with continuous progress of mining, and of course, the gases are transported away from the tunneling roadway along with continuous ore removal, so that the gas concentration of the tunneling roadway maintains dynamic safe concentration. However, factors forming the stability of mines or veins are complex and variable, and in combination with the above, for example, a plurality of tunneling roadways for mining in the same mining area are provided, and once the tunneling roadways are mutually excavated in the process of tunneling and mining operation, gas in at least one tunneling roadway is easily leaked into another tunneling roadway communicated with the tunneling roadway, so that the concentration of the gas in the corresponding tunneling roadway is changed; or when the surface of the inner wall of the tunneling roadway is seriously damaged, the tunneling roadway is easy to communicate with other undeveloped areas in the coal mine, if the areas are rich in gas, the gas in the areas can leak into the tunneling roadway, the gas content in the tunneling roadway is increased, and the potential risk of gas explosion is further formed.
On the other hand, when the underground mining area is formed at the position of the river bed, if the inner wall of the tunneling roadway is damaged once in the process of mining operation of tunneling equipment in the tunneling roadway, water leakage is easy to occur, and even the water leakage damage position is subjected to excessive water pressure, so that crushing is caused.
Therefore, in order to timely feed back the risk of gas leakage or water leakage caused by the breakage of the inner wall of the tunneling roadway, a detection vehicle set can be arranged on the inner wall of the tunneling roadway, specifically speaking, the detection vehicle set comprises a sliding rail and a detection trolley, and the detection trolley is controlled to move on the sliding rail according to a preset path so as to detect the surface of the corresponding inner wall of the tunneling roadway, so that the acquired surface information is analyzed. For example, the detection trolley comprises a body and a detection assembly, the body is in sliding connection with the sliding rail, the detection assembly is connected to the body, the signal light emitting port of the detection assembly is arranged towards the direction of the inner wall, and the detection assembly emits detection signal light towards the inner wall through the signal light emitting port. Therefore, in the rotation process of the detection assembly, the detection area projected on the inner wall is formed by the emitted detection signal light, and whether the part of the inner wall corresponding to the detection area at the moment meets the early warning state is judged by acquiring the surface information of the inner wall corresponding to the detection area. The early warning state includes, for example, the occurrence of a crack, and when the crack occurs, only the potential risk of water leakage and/or gas leakage is represented. Correspondingly, the part corresponding to the crack can be defined as a risk area through the detection assembly, compared with other areas on the inner wall, the detection assembly can be controlled to improve the detection importance degree of the risk area, and the detection assembly is particularly improved in the reciprocating scanning times of the risk area in the detection period, so that the crack change condition in the risk area in a continuous time period is obtained, the actual condition of a tunneling roadway can be reflected more accurately, and the effect of timely early warning is achieved.
Further, when a risk area appears on the inner wall, although the risk of potential water leakage and gas leakage can be determined according to the change condition of the crack, if the crack is kept unchanged, the detection component still needs to detect the gas concentration in the corresponding risk area in the detection period, or the water leakage condition is analyzed. When the detection vehicle group performs a detection action on the risk area in the detection period, the detection vehicle group is specifically characterized in that the gas concentration of the risk area is detected, and then the gas concentration of other areas adjacent to the risk area is compared, so that whether gas leakage exists in the risk area or not is judged according to a comparison result, for example, the gas concentration detected in the risk area is higher than that of the other areas, and the gas leakage in the risk area is judged.
In addition, the detection action of the detection vehicle group specifically further comprises the steps of intercepting a plurality of picture images of corresponding risk areas in a continuous time period, analyzing whether dynamic characteristic changes in the picture images accord with water leakage conditions or not, and further sending corresponding early warning by the detection vehicle group. Specifically, the dynamic feature can be specifically used for comparing the feature information of the inner wall surface when water leakage occurs in the risk area, if water leakage occurs in the risk area, the feature information of the corresponding water hole is obviously distinguished from the feature information of other parts flowing through the water flow, wherein the water hole continuously appearing on the water flow is formed on the inner wall surface. Therefore, when the dynamic characteristic change is judged to be in accordance with the water leakage condition, the risk area is indicated to have the characteristic information matched with the water hole. Similarly, in the process of executing the spraying action by the spraying equipment, if the water flow is attached to the inner wall surface, the water flow characteristics of the inner wall surfaces under the condition are unified and similar and are obviously different from the characteristics of water holes, so that the influence of misjudgment caused by the execution of the spraying action by the spraying equipment is effectively avoided by detecting the dynamic characteristic information change analyzed by the vehicle group as the basis for judging whether water leaks or not.
It should be noted that when the inner wall of the tunneling roadway is simultaneously pre-warned of gas leakage and/or water leakage and the pre-warning requirement is met with respect to the propagation trend of the suspended dust, the above mentioned countermeasures of the crack situation are preferably considered, for example, constructors in the countermeasures are preferably indicated to leave from the tunneling roadway, and then the spraying equipment is controlled to execute the spraying action.
Preferably, the dust concentration in the central area is defined as P1, the dust concentration in the middle area is defined as P2, and the dust concentration in the peripheral area is defined as P3; the control locates the spraying equipment in the operation tunnel and carries out the spraying action to the central area in the operation tunnel at least, include: when any one of the P1, the P2 and the P3 is more than or equal to K1, the tunneling equipment is controlled to stop running, and after the tunneling machine stops running, the spraying equipment is controlled to sequentially execute the cyclic spraying action on the central area, the middle area and the peripheral area; when all of P1, P2 and P3 are smaller than K1, determining the order of the spraying equipment to execute the cyclic spraying action according to the dust concentration of the suspended dust in the central area, the middle area and the peripheral area; and/or determining the duration of the cyclic spraying action executed by the spraying equipment and the spraying quantity in unit time according to the coverage rate of the suspended dust in the central area, the middle area and the peripheral area; wherein K1 is a preset lower explosion limit concentration value corresponding to the suspended dust.
