Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Examples
As shown in fig. 1, the management control system for the improved impeller coal feeder based on big data can accurately control the action track and the coal feeding rate of the impeller coal feeder by arranging a plurality of radio frequency positioning modules and a plurality of sensors arranged on the impeller coal feeder, and deduce whether a fault obstacle exists in an operation track or not by the time when the coal feeder reaches each position acquisition point, so that the operation state of the impeller coal feeder can be accurately monitored, and workers can conveniently carry out fixed-point overhaul on the operation track of the impeller coal feeder in the later period. Specifically, the management control system includes: the system comprises a host control module 10, a wireless transmission module 20, a position detection module 30 and a state monitoring module 40, wherein the host control module 10 is used for regulating and controlling the whole management control system, the host control module is respectively in communication connection with the position detection module 30 and the state monitoring module 40 through the wireless transmission module 20, the host control module 10 receives state information monitored by the position detection module 30 and the state monitoring module 40, and sends control signals according to the state information to control the motion state of the impeller coal feeder through the wireless transmission module 20, so that the safe and efficient work of the impeller coal feeder is ensured by timely and accurately removing faults. The wireless transmission module 20 is used for communication transmission between the host control module 10 and the impeller coal feeder and other modules, so that monitoring information and control signals can be timely and effectively transmitted, and the whole system is stable and efficient. The position detection module 30 is used for monitoring the operation position of the impeller coal feeder, and uploading the position information of the impeller coal feeder to the host control module 10 through the wireless transmission module 20, so that the accurate monitoring of the position of the impeller coal feeder is ensured. The state monitoring module 40 is used for monitoring the residual coal amount of the impeller coal feeder, so that the host control module 10 can adjust the coal feeding speed of the impeller coal feeder according to the residual coal amount information to complete the full-automatic coal feeding process of the impeller coal feeder.
As a further optimization improvement, the invention needs to determine the travelling section of the impeller coal feeder while determining the specific position of the impeller coal feeder. Therefore, the position detection module 30 of the present invention adopts a radio frequency identification technology, specifically, as shown in fig. 3, the position detection module 30 includes a mobile radio frequency tag 31 disposed on the surface of the impeller coal feeder and a plurality of radio frequency card readers 32 disposed on the travelling track of the impeller coal feeder; the radio frequency reader 32 reads the mobile radio frequency tag 31 on the impeller coal feeder so as to determine the actual position of the impeller coal feeder, the radio frequency reader 32 is densely arranged, the real-time position of the impeller coal feeder is determined, the specific number of the radio frequency reader 32 can be set according to actual needs, the track between every two radio frequency readers 32 is the travelling section of the upper section of the impeller coal feeder, and the running state of the travelling track can be predicted by the time that the impeller coal feeder reaches the radio frequency reader 32. Meanwhile, the mobile radio frequency tag 31 needs to be provided with one on each impeller feeder, which represents the mobile coordinates of the impeller feeder.
In order to more conveniently compare the time of the impeller coal feeder passing through each section of travelling rail so as to judge the running state of the travelling rail, the radio frequency card readers 32 are uniformly arranged on the travelling rail of the impeller coal feeder, so that the time of the impeller coal feeder reaching each radio frequency card reader 32 under the same power is ensured to be consistent when the running states of the travelling rails are consistent. And further, the running state of the running track is converted into the time that the impeller coal feeder reaches each radio frequency card reader 32, so that the host control module 10 can conveniently judge whether the running track needs to be overhauled in the background comparison time.
As a further optimization improvement, in order to effectively monitor the running state of the running track of the impeller coal feeder and give an alarm prompt while managing and monitoring the running state of the impeller coal feeder, as shown in fig. 2, the host control module 10 includes an analysis unit 11 and an alarm unit 12, where the analysis unit 11 receives the monitoring signals sent by the position detection module 30 and the state monitoring module 40, analyzes and determines whether the running track of the impeller coal feeder has a fault according to the monitoring signals, and sends a control signal to the alarm unit 12 to make the alarm unit 12 send an alarm signal.
As a further optimization improvement, the method for analyzing and judging whether the traveling track of the impeller coal feeder has faults by the analysis unit 11 comprises the following steps:
step S1, setting operation parameters of the impeller coal feeder, including engine output power, coal feeding rate of the coal feeder and the like, and determining standard reaching time through the engine output power and the track length of the adjacent radio frequency card reader 32.
And S2, setting the time to reach a threshold value, namely adding a certain time allowance as an error buffer value according to the standard reaching time determined in the step S1, so as to form the impeller coal feeder with the time reaching the threshold value and reaching the position of the designated radio frequency card reader 32 at the threshold time into a normal running state.
And step S3, determining whether the time for the impeller coal feeder to reach the position of the designated radio frequency card reader 32 is within the time set in the step S2, if so, continuing to repeat the step S3, and if not, executing the step S4 to further judge.
Step S4, judging the reason of the abnormal arrival time, specifically, judging by determining whether the output power of the engine of the impeller coal feeder is normal or not, including step S4.1 and step S4.2, wherein step S4.1 specifically, if the output power of the engine of the impeller coal feeder is normal, the travelling track between the two radio frequency card readers 32 which are recently arrived is marked as a section to be repaired; and S4.2, specifically, if the output power of the engine of the impeller coal feeder is adjusted to be normal, the impeller coal feeder is marked, and a worker waits for the follow-up maintenance of the marked impeller coal feeder.
The invention sets a time to reach the threshold value, the impeller coal feeder which does not reach the time to reach the threshold value basically and seriously influences the production efficiency, and determines whether the problem is that the impeller coal feeder is damaged or the travelling rail is damaged through further confirmation in the step S4. Therefore, the running problem can be found in time, and the whole system is more stable and efficient.
In the coal conveying system, for long-distance running tracks, there is often not only one impeller coal feeder working on the long-distance running tracks, so that step S5 is further included after step S4.1, namely, the running parameters of the subsequent impeller coal feeders are adjusted, so that the running of the system is more efficient and stable in the process of waiting for overhaul. Specifically, when the arrival time is delayed due to the damage of the travelling track, the engine output power of the latter impeller coal feeder is properly improved according to the arrival time of the former impeller coal feeder, so that the subsequent impeller coal feeder can operate more efficiently and stably.
Meanwhile, after step S4.2, the impeller coal feeder has too slow travel time in the previous path section, and the coal feeding rate is unchanged, so that the coal feeding is excessive. Therefore, step S6 follows step S4.2, specifically, when the arrival time is abnormal due to the abnormal output power of the engine of the impeller coal feeder, the coal feeding rate is appropriately changed according to the arrival time, so that the stable output of the coal feeding process is ensured. By the arrangement, the phenomenon that the internal coal is not completely fed out due to the fact that the impeller coal feeder moves too fast or too slow is avoided.
As a further optimization improvement, as shown in fig. 4, the state monitoring module 40 of the present invention includes a coal amount sensor 41 for monitoring the coal content in the impeller coal feeder in real time, and since the time taken for the impeller coal feeder to travel to each radio frequency card reader 32 is determined and the self coal feeding rate of the impeller coal feeder is fixed, the analysis unit can analyze and determine whether the coal feeding rate of the impeller coal feeder is abnormal or not according to the coal amount information transmitted by the coal amount sensor 41 at the position detection point of the impeller coal feeder (the position of each radio frequency card reader 32), and send a control signal to the alarm unit 12, so that the alarm unit 12 sends an alarm signal. Specifically, when the coal amount is normally decreased, the analysis unit 11 sends a control signal to the impeller coal feeder, and adjusts the coal feeding rate of the impeller coal feeder, thereby completing the coal feeding process of the impeller coal feeder.
The host control module 10 of the invention also comprises a data storage unit 13 and a display unit 14, wherein the data storage unit 13 is used for storing the operation data of the impeller coal feeder, so that the operation data are convenient for subsequent workers to find and overhaul, and the display unit 14 is used for displaying the operation state of each traveling road section, the alarm signal of the alarm unit 12 and the storage information of the storage unit 13, which are analyzed by the analysis unit 11, so that the subsequent workers can find and observe conveniently.
The wireless transmission module 20 of the present invention adopts a wireless radio frequency chip transmission technology, which includes various communication technologies based on 433hz,800hz,2.4G or 5G technologies, such as bluetooth, WIFI, zigbee, xbee, etc.
The host control module 10 adopts PLC control, has strong control function, and simultaneously has relatively less system maintenance, thus being very suitable for industrial production.
In summary, according to the improved impeller coal feeder management control system based on big data, the plurality of radio frequency card readers 32 are arranged on the travelling rail of the impeller coal feeder, and the mobile radio frequency tag 31 is arranged on the surface of the impeller coal feeder, so that on one hand, the running state and the running position of the impeller coal feeder can be accurately determined through radio frequency information, and on the other hand, the running state of the travelling rail of the impeller coal feeder can be predicted through the analysis unit 11, and the accurate overhaul of later-stage staff is facilitated.
