The embodiment of the application also discloses a leaky cable drop monitoring system.
Referring to fig. 5, the leaky cable disconnection monitoring system includes a communication subsystem 1, a data acquisition subsystem 2, a sending subsystem 3, a receiving subsystem 4 and a data analysis subsystem 5. The communication subsystem 1 is in communication connection with the collector through the leaky cable to acquire position information and independent address codes of the collector, after the connection is established, the data acquisition subsystem 2 receives initial angle data of the leaky cable or the leaky cable lifting appliance acquired by the collector, the sending subsystem 3 receives the address codes of the collector from the communication subsystem 1, generates a command packet according to the address codes, sends the command packet to the collector according to preset sending time, and regularly sends the command packet, so that resources are saved.
The collector receives the command packet with the same address code, then the response data packet is recovered, the response data packet is received through the receiving subsystem 4, if the response data packet is not received, the communication with the collector is interrupted, and the cable leakage or cable leakage hanger where the collector is located falls off or other abnormal conditions occur, at this time, the position information of the collector needs to be sent to the management center through the receiving subsystem 4, so that the management center dispatches workers to check the collector. If the receiving subsystem 4 receives the response data packet, the data analysis subsystem 5 analyzes the data of the response data packet, analyzes the falling condition of the leaky cable or the leaky cable lifting appliance, and informs the management center according to the falling condition, so that the leaky cable or the leaky cable lifting appliance is monitored in real time.
Referring to fig. 6, the data analysis subsystem 5 includes a parsing module 51, a calculation module 52, a judgment module 53, a statistics module 54, an event analysis module 55, and a notification module 56. The analysis module 51 analyzes the response data packet to obtain real-time angle data of the leaky cable or the leaky cable hanger collected by the collector, the calculation module 52 calculates an angle difference between the real-time angle data and the initial angle data after receiving the real-time angle data from the analysis module 51 and the initial angle data from the data collection subsystem 2, the judgment module 53 preset with an angle threshold receives the angle difference and judges the angle difference to judge whether the leaky cable or the leaky cable hanger falls off, if the leaky cable or the leaky cable hanger falls off, a falling range needs to be further counted by the counting module 54 according to the real-time data, so that the incident analysis module 55 analyzes an incident grade of the falling event according to the falling range and the angle difference, the incident grade reflects the severity of the falling event, and the reporting module 56 generates different reporting information according to the difference of the incident grade, and the notification information is sent to the management center so that the management center can flexibly schedule the maintenance personnel.
Referring to fig. 7, the event analysis module 55 includes a distance calculation unit 551, a first analysis unit 552, and a second analysis unit 553, and the notification module 56 includes a first notification unit 561 and a second notification unit 562. Firstly, the falling distance of the leaky cable or the leaky cable hanger is calculated through the distance calculating unit 551, then the falling distance is judged through the first analyzing unit 552 with a preset distance threshold, and when the falling distance is greater than the distance threshold, the situation of the falling event is serious, so that the situation grade obtained through analysis is a first grade; when the falling distance is smaller than the distance threshold, the falling range is further judged by a second analysis unit 553 with a preset range threshold, and when the falling range is larger than the range threshold, the falling leaking cable or the leaking cable hanger is more, the situation is more serious, and therefore the first grade is obtained through the same analysis; when the falling distance is smaller than the distance threshold and the falling range is smaller than the range threshold, the condition is controllable although the leaky cable or the leaky cable lifting appliance falls off, and therefore the analysis condition grade is the second grade.
When the status level is the first level, it indicates that the drop condition of the leaky cable or the leaky cable lifting appliance is serious, the first reporting unit 561 generates first reporting information and sends the first reporting information to the management center, so that the management center notifies emergency repair personnel to perform emergency repair through the emergency repair information; when the status level is the second level, it is described that the drop condition of the leaky cable or the leaky cable hanger is within the controllable range, at this time, the second reporting unit 562 generates second reporting information and sends the second reporting information to the management center, so that the management center notifies a troubleshooting worker to perform troubleshooting and maintenance on the leaky cable or the leaky cable hanger through the troubleshooting information.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
