Description

Technical Field

[0001] The present invention relates to the field of platform screen doors, and more specifically, to an intelligent operation and maintenance system for platform screen doors. Background Art

[0002] At present, the operation and maintenance mode of the platform screen door system mainly focuses on fault repair and planned repair. This maintenance mode not only consumes a large amount of manpower for equipment maintenance work, but also is very likely to cause uneven equipment maintenance, reduce the service life of the equipment. The main reason for this phenomenon is that the existing platform screen door system has insufficient detection points for system operation, that is, on the one hand, the platform screen door system and each DCU need to transmit service data, and on the other hand, they need to transmit operation status data, resulting in transmission jams and insufficient processing capabilities. More importantly, due to the structural limitations of the existing platform screen door hardware system, it is impossible to add additional detection points in the original system.

[0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Summary of the Invention

[0004] In order to achieve the above object, the technical solution adopted by the present invention is: an intelligent operation and maintenance system for platform screen doors, including a main control cabinet PSC, a door control unit DCU, a logic control unit PEDC, an industrial computer, an integrated monitoring system, and a power supply cabinet; state monitoring modules are provided on both the door control unit DCU and the main control cabinet PSC; the logic control unit PEDC, the door control unit DCU, the main control cabinet PSC, and the power supply cabinet are all communicatively connected to a server through an intelligent operation and maintenance host;

[0005] The intelligent operation and maintenance host is directly communicatively connected to the logic control unit PEDC through a first data communication interface to read the operation data of the platform screen door system output by the logic control unit PEDC; the intelligent operation and maintenance host is communicatively connected to the industrial computer through a second data communication interface to read the hardware operation data of the industrial computer; the intelligent operation and maintenance host is communicatively connected to the power supply cabinet through a third data communication interface to read the operation data of the power supply cabinet, and the intelligent operation and maintenance host is communicatively connected to the state monitoring module through a fourth data communication interface to read the monitoring module operation data detected by the state monitoring module;

[0006] The intelligent operation and maintenance host uploads the read operation data of the platform screen door system, the hardware operation data of the industrial computer, the operation data of the power supply cabinet, and the operation data of the monitoring module to the server for data analysis respectively, and gives an early warning prompt for the components whose performance reaches the threshold according to the analysis results, and determines the faulty components of the platform screen door system.

[0007] Based on the above, an industrial computer remote reset module is further connected to the industrial computer.

[0008] Based on the above, when a failure occurs, the intelligent operation and maintenance host obtains the platform door system failure data fed back by the logic control unit PEDC through the first data communication interface, and the intelligent operation and maintenance host obtains the real-time monitoring module operation data monitored by the status monitoring module through the fourth data communication interface;

[0009] The intelligent operation and maintenance host uploads the read platform door system failure data and real-time monitoring module operation data to the server for data analysis and comparison respectively, and then judges the specific faulty component that has failed, and then sends the fault information to the maintenance personnel's maintenance terminal.

[0010] Based on the above, the server is also communicatively connected to a material management system; after the server determines the faulty component, it sends the material code corresponding to the faulty component to the material management system. After the material management system queries the storage information of the faulty component materials and feeds it back to the server, the server then sends the fault time, fault station, fault equipment location, fault cause judgment, and component storage location information to the maintenance personnel's maintenance terminal.

[0011] Based on the above, the status monitoring module includes a temperature sensor, a humidity sensor, an acceleration sensor, a displacement detection sensor, a voltage sensor, a current sensor, a speed sensor, and a position sensor, as well as an optocoupler and a relay that implement a physical isolation function.

[0012] Based on the above, the server is also communicatively connected to a graphical display module. When the server cannot perform fault analysis on the faults occurring on-site, the server feeds back the fault information to the graphical display module, and the relevant status is displayed on the maintenance terminal through the graphical display interface.

[0013] Based on the above, the main control cabinet PSC issues a control instruction, and the door control unit DCU controls the sliding door to open and close according to the instruction and feeds back the data of the door control unit DCU to the logic control unit PEDC. The logic control unit PEDC uploads the PEDC relay status and the door control unit DCU data to the industrial control computer through an internal data conversion circuit, and the industrial control computer stores the data and then sends it to the integrated monitoring system.

[0014] The present invention has prominent substantial features and remarkable progress compared with the prior art. Specifically, a platform door intelligent operation and maintenance system provided by the present invention has the following advantages:

[0015] (1) The status monitoring module uses temperature sensors, humidity sensors, acceleration sensors, displacement detection sensors, speed sensors, and position sensors to detect the operating environment and mechanical part status of the platform screen door system. The detection circuit of this part is completely independent of the platform screen door system. At the same time, the status monitoring module classifies the detected data, uploads the operation status data in real time, and uploads the fault analysis data according to requirements, reducing the amount of transmitted data.

[0016] (2) The intelligent operation and maintenance system is independent of the platform screen door system. When the intelligent operation and maintenance system is upgraded and optimized, it will not affect the normal operation of the platform screen door system. At the same time, the data does not need to be processed by the industrial control computer, ensuring the authenticity of the data received by the intelligent operation and maintenance host, and avoiding data transmission interruption caused by the abnormality of the industrial control computer.

[0017] (3) The intelligent operation and maintenance system has the function of remotely restarting the industrial control computer. The intelligent operation and maintenance host and the industrial control computer regularly send handshake signals to judge whether the industrial control computer has crashed or software problems. When problems occur, the industrial control computer can be remotely restarted by the maintenance dispatcher or maintenance personnel.

[0018] (4) The intelligent operation and maintenance host reads the operation data of the power supply cabinet through the data communication interface, which can be used for analyzing the operation status of the power supply cabinet and fault analysis of the platform screen door.

[0019] (5) After the intelligent operation and maintenance host integrates all the data, it uploads the data to the server through the interface for data storage and data processing. The intelligent operation and maintenance host can adopt an industrial control computer or a single-chip microcomputer circuit. When using an industrial control computer, the data can be initially stored or processed on the intelligent operation and maintenance host, reducing the operation pressure on the network-level server.

[0020] (6) The integrated monitoring system and the intelligent operation and maintenance system in the platform screen door system simultaneously detect the status of the platform screen door. The intelligent operation and maintenance host simultaneously collects the data of the two systems and conducts consistency analysis on the data to achieve mutual inspection of the system status and ensure the accuracy of the data.

[0021] (7) The intelligent operation and maintenance system has an automatic alarm function. When the intelligent operation and maintenance host detects a platform screen door fault, it can send the fault information to the maintenance terminal to notify the maintenance personnel to handle the fault, changing the problem of low efficiency of manual fault feedback in the existing maintenance mode. At the same time, during fault analysis, the intelligent operation and maintenance host triggers the fault analysis function by reading the original system fault data of the platform screen door, reads the data of the intelligent detection module of the relevant fault unit according to the platform screen door fault information, conducts fault analysis, and sends the analysis result to the maintenance terminal. The maintenance personnel can directly reach the site according to the display to replace the faulty parts.

[0022] (8) The platform door intelligent operation and maintenance system can also perform fault analysis in a graphical display mode. When certain faults occur on-site and are of the fault categories that the intelligent operation and maintenance system cannot analyze, the relevant status can be displayed on the maintenance terminal through the graphical display interface, realizing the function of remote expert diagnosis for difficult faults. At the same time, this graphical display can also perform the function of viewing the remote device operation status.

[0023] (9) The platform door intelligent operation and maintenance system can perform fault early warning. When the intelligent operation and maintenance platform detects that the operation status of a certain component is lower than the warning value, a fault early warning signal will be sent to the maintenance terminal. The maintenance personnel will repair the component after the operation stops, solve the potential fault hazards in advance, and prevent the occurrence of equipment failures.

[0024] (10) The platform door intelligent operation and maintenance system also has an intelligent material management function. When the intelligent operation and maintenance platform detects a faulty component or a component with a substandard operation status, it can automatically match the relevant spare parts in the warehouse and automatically complete the spare part borrowing process. When the maintenance personnel do not replace the spare parts on-site, the spare part return process will be automatically completed after the spare parts are returned; when the maintenance personnel replace the spare parts on-site, the borrowing will be automatically changed to material requisition, realizing the intelligent material management function and avoiding the impact of material requisition on on-site fault handling.

[0025] In summary, the platform door intelligent operation and maintenance system realizes the separation of control and inspection for intelligent operation and maintenance of platform doors, and at the same time greatly reduces the data storage volume of the intelligent operation and maintenance host, thus effectively solving the two problems of fault diagnosis and equipment operation status monitoring in the implementation process of the platform door intelligent operation and maintenance system; it can greatly reduce the disadvantages of large maintenance workload, low efficiency, and high maintenance cost in the existing operation and maintenance system, and has strong promotion potential.

[0028] The technical solutions of the present invention will be further described in detail below through specific embodiments.

[0029] Embodiment 1

[0030] This embodiment provides a platform door intelligent operation and maintenance system, as Figure 1 and Figure 2As shown in the figure, it includes a main control cabinet PSC, a door control unit DCU, a logic control unit PEDC, an industrial computer, an integrated monitoring system, and a power supply cabinet; state monitoring modules are provided on both the door control unit DCU and the main control cabinet PSC; the logic control unit PEDC, the door control unit DCU, the main control cabinet PSC, and the power supply cabinet are also communicatively connected to a server through an intelligent operation and maintenance host.

[0031] The intelligent operation and maintenance host is directly communicatively connected to the logic control unit PEDC through a first data communication interface to read the operation data of the platform door system output by the logic control unit PEDC; the intelligent operation and maintenance host is communicatively connected to the industrial computer through a second data communication interface to read the hardware operation data of the industrial computer; the intelligent operation and maintenance host is communicatively connected to the power supply cabinet through a third data communication interface to read the operation data of the power supply cabinet, and the intelligent operation and maintenance host is communicatively connected to the state monitoring module through a fourth data communication interface to read the operation data of the monitoring module detected by the state monitoring module.

[0032] The intelligent operation and maintenance host uploads the read operation data of the platform door system, the hardware operation data of the industrial computer, the operation data of the power supply cabinet, and the operation data of the monitoring module to the server for data analysis respectively, and gives early warning prompts for components whose performance reaches the threshold according to the analysis results, and determines the faulty components of the platform door system.

[0033] Among them, an industrial computer remote reset module is also connected to the industrial computer.

[0034] When a fault occurs, the intelligent operation and maintenance host obtains the platform door system fault data fed back by the logic control unit PEDC through the first data communication interface, and the intelligent operation and maintenance host obtains the real-time operation data of the monitoring module monitored by the state monitoring module through the fourth data communication interface.

[0035] The intelligent operation and maintenance host uploads the read platform door system fault data and the real-time operation data of the monitoring module to the server for data analysis and comparison respectively, then determines the specific faulty components that have occurred, and then sends the fault information to the maintenance terminal of the maintenance personnel.

[0036] In this embodiment, the server is also communicatively connected to a material management system; after the server determines the faulty components, it sends the material codes corresponding to the faulty components to the material management system. After the material management system queries the storage information of the faulty component materials and feeds it back to the server, the server then sends the fault time, fault station, fault equipment location, fault cause judgment, and component storage location information to the maintenance terminal of the maintenance personnel.

[0037] Specifically, the state monitoring module includes a temperature sensor, a humidity sensor, an acceleration sensor, a displacement detection sensor, a voltage sensor, a current sensor, a speed sensor, a position sensor, as well as an optocoupler and a relay for realizing the physical isolation function.

[0038] The server is also communicatively connected to a graphical display module. When the server cannot perform fault analysis on the faults occurring on-site, the server feeds back the fault information to the graphical display module, and the relevant status is displayed on the maintenance terminal through the graphical display interface.

[0039] The main control cabinet PSC issues a control instruction. The door control unit DCU controls the sliding door to perform the opening and closing actions according to the instruction and feeds back and uploads the data of the door control unit DCU to the logic control unit PEDC. The logic control unit PEDC uploads the PEDC relay state and the data of the door control unit DCU to the industrial control computer through the internal data conversion circuit, and the industrial control computer stores the data and then sends it to the integrated monitoring system.

[0040] To better introduce the working principle of the fault detection of this system, this embodiment takes the sliding door unlocking fault reported by the platform door system as an example to introduce the working principle of the fault detection.

[0041] As Figure 2 shown, it is the flowchart of the work from the DCU issuing the unlocking instruction to the execution of the sliding door opening part. When working normally, after the DCU issues the electromagnet suction instruction, it judges whether the brake lock is normally unlocked through the state of the lock-in place switch. After receiving the action instruction of the lock-in place switch, the DCU judges that the brake lock is normally unlocked, and this sliding door opens; if the action state of the lock-in place switch is not received, an unlocking fault is reported.

[0042] This control method mainly has the following problems: The electromagnet suction instruction issued by the DCU is transmitted to the electromagnet by controlling the relay, and there is a lack of corresponding detection for whether the control relay outputs normally; the DCU judges the state of the lock-in place detection switch through the internal optocoupler, and when a fault occurs, it is impossible to judge whether the fault point is the DCU or the lock-in place detection switch. Therefore, when an unlocking fault occurs, it is impossible to accurately judge the specific faulty component according to the fault record, and it is necessary to manually test on-site to judge whether the fault is caused by the DCU fault or the brake lock fault.

[0043] For the sliding door unlocking fault reported by the platform screen door system, the intelligent operation and maintenance system for platform screen doors provided in this embodiment mainly adds two detection points to respectively detect the electromagnet suction instruction of the DCU control relay and the status of the lock-in-place detection switch. When the platform screen door system reports a sliding door unlocking fault, after the intelligent operation and maintenance system detects the fault data through the first data communication interface, it reads the data of the fault equipment status monitoring module through the fourth data communication interface. The specific faulty component can be judged based on the data of the two detection points, and the fault information and the faulty component information are sent to the mobile terminal. The maintenance personnel replace the fault according to the mobile terminal data.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
