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 flow chart of a comprehensive control method for a coal mine intelligent park according to an embodiment of the invention is shown. The intelligent coal mine park comprises construction modules which are correspondingly arranged in a coal mine area, wherein the construction modules are used for constructing a mine channel, a middle tunnel and an operation tunnel which are communicated with each other in the coal mine area; the construction module comprises a patrol unit which is arranged in a transmission channel formed by a mine channel and a middle roadway; the comprehensive control method specifically comprises the following steps:
step S1, acquiring state information of a transmission channel through a patrol unit arranged on the inner wall of the transmission channel; wherein the status information includes surface breakage information generated from the inner wall.
And S2, judging whether the transmission channel meets a first early warning state according to the state information.
And S21, if yes, controlling the inspection unit to move to a first position corresponding to the first early warning state, and executing a leakage detection action on the first position through a detection part of the inspection unit to acquire detection information.
Step S22, if not, the inspection unit is controlled to keep the first inspection operation on the inner wall.
And step S3, judging whether the transmission channel is in a leakage state or not according to the detection information.
And S31, if the construction module is in the leakage state, controlling the construction module to execute the emergency command according to the leakage type corresponding to the leakage state.
Step S32, if the first position is not in the leakage state, the inspection unit is controlled to execute periodic second inspection operation on the first position. Wherein the leakage type comprises gas leakage and/or water seepage.
Step S4, after the construction module executes the emergency command, emergency information corresponding to the emergency command is sent to an administrative management module of the coal mine intelligent park, and the administrative management module calls standard risk avoidance response information matched with the emergency command from the historical database according to the emergency information; the standard risk avoidance response information corresponds to the emergency information one by one.
For example, the inspection unit includes, for example, a mobile train unit, and specifically, a monitoring device is disposed on the mobile train unit, so that the mobile train unit can monitor the corresponding position of the inner wall when the mobile train unit is paved to the track motion on the inner wall. Therefore, whether the transmission channel is in a leakage state or not is judged by monitoring the integrity of the corresponding surface of the inner wall, so that the effect of timely monitoring the specific condition of the transmission channel by means of the inspection unit can be realized, an operator can timely make emergency actions according to the information fed back by the inspection unit, and the loss caused by the leakage condition of the transmission channel is reduced. In addition, the periodic second inspection action of the inspection unit is combined, so that the inspection monitoring efficiency is further improved, and early warning reaction can be timely carried out according to the surface damage condition of the inner wall.
Specifically, in another specific example, the above-mentioned track can be arranged on the ground in the transmission channel, so that the situation that the part, which is covered by the track laid on the inner wall, is difficult to monitor in the process of monitoring the inner wall of the mobile vehicle set is avoided, and thus, a monitoring leak is formed. On the contrary, the track laid on the ground is arranged in a direction close to the inner wall, and the mobile train unit comprises a body, a mobile wheel set and a detection component for further accurately acquiring the surface condition of the inner wall of the transmission channel. The movable wheel set is connected to the bottom end of the machine body and is used for being in rolling connection with the track; the detection component is arranged at the top end of the machine body, the detection component is rotationally connected with the machine body, the signal light ray emission port of the detection component is arranged towards the direction of the inner wall, and the detection component emits detection signal light rays towards the inner wall through the signal light ray emission port. Then, the detection part rotates to form a detection area projected on the inner wall through the emitted detection signal light, and then whether the part of the inner wall corresponding to the detection area at the moment meets the first early warning state is judged by acquiring the detection information of the inner wall corresponding to the detection area.
Of course, the track laid on the ground extends along the length direction of the transmission channel, so that the mobile train unit rotates and projects detection signal light in the direction of the surface of the inner wall in combination with the detection part to obtain surface damage information on each position of the inner wall in the moving process of the track, the effect of comprehensively detecting the surface of the inner wall is improved, and the risk of missing detection is reduced.
Further, if the inspection unit detects that, for example, a breakage occurs on the inner wall, it indicates that there is a risk of gas leakage and water seepage. It should be noted that, because the transmission channels are channels formed by digging under the ground, and the characteristics of the coal mine are combined, the gas dissociated in the transmission channels is removed, that is, the gas is mainly concentrated in the operation channels, and the residual gas is adsorbed to the surface of the coal mine, for example, a plurality of transmission channels digging in the same mining area, once the plurality of transmission channels are mutually dug in the process of digging and mining, the gas in at least one transmission channel is easily leaked into another transmission channel communicated with the transmission channels, specifically, the gas in one transmission channel is leaked into the middle channel of the other transmission channels, or the two operation channels leaking the gas are communicated; or when the inner wall surface of the transmission channel is seriously damaged, the transmission channel is easily communicated with other undeveloped areas in the coal mine, if the areas are rich in gas, the gas in the areas can leak into the transmission channel, so that the gas content in the transmission channel is increased, and the potential risk of gas explosion is formed.
In addition, the inner wall of the transmission channel is damaged, so that water leakage is likely. In the underground coal mining process, a plurality of coal mines are buried in positions near the river channel, and when the coal mines are performed at the positions, the dynamic flowing flushing of river water of the river is combined, so that the structural stability of the constructed transmission channel is influenced. Then, when the inspection unit detects that the inner wall surface of the transmission channel is damaged, the transmission channel is judged to meet the first early warning state, namely the risk of gas leakage or water leakage exists.
Further, when the transmission channel satisfies the first early warning state, it does not mean that the gas leakage or water leakage is already performed at this time. More specifically, when the damage is not serious, for example, only the surface layer on the smaller area of the inner wall is dropped, the inspection unit is controlled to maintain the second inspection operation, wherein the second inspection operation may specifically be represented as that the inspection unit is stopped at the position of the track, the inspection unit is rotated relative to the machine body to inspect the surface condition of the transverse area along the transmission channel, and then the inspection unit is controlled to move in the track, that is, move along the longitudinal length direction of the transmission channel, and the above-mentioned inspection of the surface condition of the transverse area along the transmission channel is repeated. Of course, when the transmission channel satisfies the first early warning state, the area where the damage occurs on the inner wall is defined as a risk area, so that in the process of executing the second inspection action, the detection duty ratio of the inspection unit to the risk area is increased, for example, the detection times of the detection part rotating reciprocally to sweep the risk area is increased, or the detection duration of the detection part staying in the risk area is increased. And the second inspection action is kept on the inner wall by controlling the inspection unit so as to acquire the surface damage information of the inner wall to the greatest extent in time.
Of course, when a plurality of risk areas appear on the surface of the inner wall, the specific gravity execution such as the detection duration or the detection times of the inspection unit on the plurality of risk areas may be controlled, or the second inspection operation may be executed according to the priority that the surface area of the surface damage in the plurality of risk areas is larger, and the second inspection operation may be executed after the surface area of the surface damage is smaller.
Further, when the transmission channel is judged to be in the leakage state, the detection information may specifically include water seepage information and gas information. In a specific example, the detection component includes a dynamic identification module, where the dynamic identification module is used to identify and detect the water seepage condition of the inner wall corresponding to the first position and convert the water seepage condition into corresponding water seepage information, so that the control construction module according to the water seepage information can specifically include backup construction operation information of the construction module so as to extract the construction operation at the first time to perform the working state when the normal operation is restored next time, and of course, the control construction module can be controlled to take waterproof measures, especially, the power supply equipment in the construction module can be in a waterproof state, so that damage to the power supply equipment when water seepage is serious is avoided, especially, the power supply equipment is not in a waterproof state and runs to cause water contact short circuit, and the internal circuit condition is burnt.
Furthermore, the history database can be understood as a standard risk avoidance response measure corresponding to the standard risk avoidance response information causing the minimum loss, which is adopted by the stored coal mine intelligent park when the leakage condition occurs in the history. It should be noted that the standard risk avoidance response measure indicated herein may also be a standard response measure taken when other coal mine historic periods have a leak. Of course, in order to ensure that the enforceability of taking the standard hedging response actions corresponding to the standard hedging response information is safe enough and the loss which can be caused is minimum, the data stored in the historical database is the standard hedging response information disclosed in the coal mine intelligent park and other coal mine areas. The standard risk avoidance response information is a standard measure accepted in the art, and is not described herein.
Thus, the loss suffered by the coal mine intelligent park can be ensured to be minimum by adopting standard risk avoidance response information matched with the emergency information.

Specifically, when the environmental parameter value is, for example, a gas concentration parameter value, the gas concentration parameter value formed at the air outlet is detected for a plurality of times to further obtain the gas content in the operation roadway. In short, the working roadway needs to mine within the gas safety concentration range to ensure normal mining operation so as to ensure personal safety of constructors. In the process of tunneling and mining, the gas concentration in the operation tunnel can change, and in order to improve the detection accuracy, the gas concentration needs to be detected for multiple times at the air outlet.

Thus M is a set representing the values of the gas concentration parameter acquired during the first preset time period, M min For the minimum value in the set M, M max Is the maximum value in set M. For example, the gas concentration parameter values may be collected every 5 seconds, and C1 is the gas concentration parameter value collected for the first time within the first preset time period, and C2 is the gas concentration parameter value collected from 5 seconds after the collection of C1 until Ct is collected at time t. Wherein C0 is used for representing a preset environmental parameter value capable of safely operating in the operation roadway, and the environmental parameter value corresponding to the safe operation in the operation roadway is combined with a small fluctuation value around C0, namely k1 and (M) min -C0) as a preset lower limit fluctuation value, more accurately reflects whether the environmental parameter values in the operation lane meet the safety operation requirements, in contrast to k2 and (M) max The same holds true for the product of C0) as the preset offline ripple value, which is not described here again.
