Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a method and system for independently collecting power data in a rail transit integrated monitoring system. Background Art

[0002] In traditional rail transit integrated monitoring, the integrated monitoring platform usually communicates with other subsystems including the power monitoring system through the acquisition server of the control center. The acquisition server undertakes all professional communication service functions of all stations. In actual on-site situations, the acquisition server is often served by a group of devices with relatively low hardware configuration, which results in the acquisition server having heavy tasks and relatively low capabilities. In addition, since all communications of the integrated monitoring platform are concentrated on the acquisition server of the control center, the role of the acquisition server in the system appears to be too important. If there is a problem with the acquisition server, resulting in the failure of power data collection, it is very unfavorable for risk prevention and also brings great inconvenience to actual work. In view of the above-mentioned defects, the present invention has made improvements. Summary of the invention

[0003] In order to overcome the shortcomings of the background technology, the present invention provides a method for independently collecting power data in a rail transit integrated monitoring system. Through the allocation and management of the data server, each server group collects the power data of the RTU respectively, and each server group controls the equipment in the RTU respectively, without affecting each other, and each server group collects and controls independently, thereby better meeting actual needs.

[0004] The present invention provides a method for independently collecting power data in a rail transit integrated monitoring system, the method comprising the following steps:

[0005] S1. Upload power data through RTU, use the data server as a management server to control other servers, and configure multiple server groups that independently collect and process RTU power data in the database of the data server. Each of the server groups includes a collection server that collects RTU power data and a processing server that processes RTU power data.

[0006] S2. Through the control of the management server, a collection server with collection authority in a server group collects the power data uploaded by the RTU and sends the received data to a processing server with processing authority in the same server group. The collection server collects the uploaded data through the collection channel corresponding to the server group.

[0007] S3. The processing server that receives the power data analyzes and processes the data and stores it in a real-time database.

[0008] Preferably, in step S1, the RTU adopts a KF6510 device, the acquisition server adopts a COM server, and the processing server adopts a SCADA server.

[0009] Preferably, in step S1, corresponding to one KF6510 device, multiple server groups that independently collect and process the power data of the KF6510 device include 1 central server group, 1 backup central server group and 1-3 station server groups. The KF6510 device is a communication device provided in the PSCADA system, and the data server, central server group, backup central server group and station server group are all provided in the NK6000 system.

[0010] Preferably, before step S1, the collection process is deployed on each COM server of each of the server groups, and the processing process is deployed on each SCADA server of each of the server groups.

[0011] Preferably, in step S2, when the independent acquisition communication of a server group is abnormal, the abnormal server group will send abnormal information to the management server. After receiving the message, the management server will allocate it to other server groups with normal independent acquisition communication. The COM server and SCADA server of the normal server group will collect and process the power data uploaded by the KF6510 device and store it in the real-time database.

[0012] Preferably, the SCADA server also publishes a power data message to the Redis server after analyzing and processing the data, so as to forward it to other systems for backup.

[0013] Preferably, in the data server, multiple communication groups are configured for the KF6510 device and each communication group corresponds to the forwarding channel of each server group. The data server manages the communication groups of each server group. When one of the server groups remotely controls a device in the KF6510 device, the control command will be sent to the device through the forwarding channel of the server group, and the control result will be fed back to the SCADA server of the server group through the forwarding channel and the status of the device will be displayed in real time. The server groups do not affect each other's control over the devices in the KF6510 device.

[0014] Preferably, after a server group sends a control command for remote control operation, if the independent control communication of the server group is abnormal, the abnormal server group will send abnormal information to the management server, and the management server will control the control command issued by the abnormal server group to be sent to the server group with normal independent control communication, and use the normal server group to send control commands and receive feedback results.

[0015] Preferably, after receiving the abnormal information, the management server will push the alarm information to the monitoring interface of the NK6000 system to notify the dispatcher to handle the abnormality in time.

[0016] The present invention also provides a rail transit integrated monitoring system for independently collecting power data, including a NK6000 system and a PSCADA system, wherein the PSCADA system includes a KF6510 device for communication, and the NK6000 system includes a data server and a plurality of server groups for independently collecting and processing power data of the KF6510 device. Corresponding to one KF6510 device, the plurality of server groups in the NK6000 system include a central server group, a backup central server group, and 1-3 station server groups;

[0017] The KF6510 device is used to upload power data;

[0018] The data server is used as a management server to control other servers. The management server configures multiple server groups that independently collect and process the power data of the KF6510 device in the database of the data server. In the data server, multiple communication groups are configured for the KF6510 device, and each communication group corresponds to the forwarding channel of each server group. The task allocation of independently collecting and processing the power data of the KF6510 device and the task allocation of issuing control commands to the equipment of the KF6510 device are determined through the data management of the management server.

[0019] The central server group includes a central COM server for collecting power data of the KF6510 device and a central SCADA server for processing power data of the KF6510 device;

[0020] The backup center server group includes a backup center COM server for collecting power data of the KF6510 device and a backup center SCADA server for processing power data of the KF6510 device;

[0021] The station server group includes a station COM server for collecting power data of the KF6510 device and a station SCADA server for processing the power data of the KF6510 device.

[0022] In summary, the beneficial effects of the present invention are:

[0023] 1. The present invention analyzes and studies the way in which the center, standby center and three stations collect power data from the KF6510 device in the rail transit integrated monitoring system. Through the allocation and management of the data server, each server group collects the power data of the KF6510 device respectively, and each server group controls the equipment in the KF6510 respectively, without affecting each other, and each server group collects and controls independently;

[0024] 2. The method for independently collecting power data in a rail transit integrated monitoring system proposed in the present invention greatly improves the collection and control efficiency, and reduces the pressure caused by the original collection by a single collection server COM, avoiding the risk that once one server group has an abnormality, other server groups cannot obtain real-time power data, and ensures that as long as the collection and processing services of one server group are running normally, other server groups can collect real-time data and publish it to the Redis server, which brings convenience to the subsequent forwarding of data;

[0025] 3. If any abnormality occurs during the independent collection of power data or independent control of equipment under the RTU, the dispatcher can receive alarm information in time to avoid unnecessary losses, which brings convenience to the smooth operation of rail transit.

[0035] The following will be combined with the embodiments of the present invention Figures 1 to 7 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In order to make the purpose, technical solution and advantages of the implementation of the present invention clearer, the technical solution in the embodiment of the present invention will be described in more detail below with reference to the accompanying drawings in the embodiment of the present invention.

[0037] like Figures 1 to 7 As shown, the present embodiment discloses a method for independently collecting power data in a rail transit integrated monitoring system, the method comprising the following steps:

[0038] S1. Upload power data through RTU, use the data server as a management server to control other servers, and configure multiple server groups that independently collect and process RTU power data in the database of the data server. Each of the server groups includes a collection server that collects RTU power data and a processing server that processes RTU power data.

[0039] S2. Through the control of the management server, a collection server with collection authority in a server group collects the power data uploaded by the RTU and sends the received data to a processing server with processing authority in the same server group. The collection server collects the uploaded data through the collection channel corresponding to the server group.

[0040] S3. The processing server that receives the power data analyzes and processes the data and stores it in a real-time database.

[0041] The above technical solution greatly improves the efficiency of collecting power data. By configuring multiple server groups and forming collection channels corresponding to each of the server groups, the pressure brought by the original collection by a single central collection server is reduced, and the risk of other server groups not being able to obtain real-time power data once an abnormality occurs in the central collection server is avoided. This ensures that as long as the collection and processing services of one server group operate normally, other server groups can collect real-time power data.

[0042] As a preferred technical solution, the RTU adopts a KF6510 device, the acquisition server adopts a COM server, and the processing server adopts a SCADA server. Furthermore, corresponding to one KF6510 device, multiple server groups that independently collect and process the power data of the KF6510 device include 1 central server group, 1 backup central server group and 1-3 station server groups. Furthermore, the KF6510 device is a communication device provided in the PSCADA system, and the data server, central server group, backup central server group and station server group are all provided in the NK6000 system.

[0043] In traditional rail transit integrated monitoring, the integrated monitoring platform NK6000 system communicates with other subsystems including the PSCADA system through the COM acquisition server of the control center. The central COM server assumes all professional communication service functions of all stations. In actual situations on site, the central COM server is often served by a group of devices with relatively low hardware configuration, which leads to the situation that the central COM server has heavy tasks and relatively low capabilities. In addition, since all communications of the NK6000 platform are concentrated in the central COM server, the role of the central COM server in the system appears to be too important. If there is a problem with the COM, the power data collection will fail, which is not conducive to risk prevention.

[0044] The KF6510 device is a communication device suitable for the electrified railway traction automation system and the urban rail transit PSCADA system, and realizes the functions of communication information aggregation, processing and transmission within the station. The network mode can adopt Ethernet, CAN-BUS, F-BUS and other methods, and the communication medium supports cables and optical fibers. The device can be installed flexibly, and can be installed in a cabinet or dispersedly installed in various places in the substation. The KF6510 device of this embodiment is a communication device installed in the substation to communicate with the NK6000 system.

[0045] The communication device KF6510 of the PSCADA system and the COM servers in each server group of the NK6000 system are connected through the internal network, and the information exchange between the two sides is also realized through the internal interface. The specific architecture diagram is as follows Figure 2 As shown. Figure 2 In the embodiment, the acquisition servers of each server group all use the main and standby COM servers, which are started at the same time. When working, one COM server actually acquires data, and the other COM server serves as a standby. Using the main and standby COM servers is a preferred implementation scheme.

[0046] The design principles of the present invention are as follows:

[0047] The KF6510 device is connected to the COM server in each server group of the NK6000 system through the network, and the two sides communicate using UDP / IP;

[0048] The connections between servers are all dual-network connections, and information transmission requires sending on both networks A and B;

[0049] One KF6510 device has the ability to communicate with the center, backup center and up to three stations of the NK6000 system; the KF6510 device and each server group can be considered independent of each other.

[0050] The IP address and receiving data port of the SCADA server are dynamic, while the IP address and receiving data port of the KF6510 device are static and fixed.

[0051] The present invention aims to optimize the performance of the NK6000 system. In terms of the connection method between NK6000 and PSCADA, the present invention proposes a solution in which the connection between the PSCADA system and the NK6000 system can not only communicate through the central COM server, but also through the backup central COM server, station COM server, etc. of the NK6000 system. In this way, power data can be independently collected well, and real-time power data can be stored through the Redis service to meet the needs of the data forwarding module.

[0052] For the power system, it is necessary to monitor the power system in real time and integrate the scattered data. In the process of real-time monitoring of the data, it is necessary to establish a corresponding database to store data information. On the one hand, it can effectively improve the efficiency of data analysis work, and on the other hand, it can effectively improve the quality of the data itself.

[0053] The present invention is based on the fact that the center, the backup center, and the three stations all need to collect power data collected by the KF6510 device. In the traditional collection process, power data is collected only through a central COM, and other server groups obtain power data at the same time after SCADA processing. However, once the collection service is abnormal, each server group will not receive real-time power data, nor can it be processed and analyzed, and it will not be forwarded to other system modules.

[0054] The present invention can understand the independent communication between the KF6510 device and the center, backup center and three stations of NK6000 as that for the same RTU, multiple server groups can collect its telesignaling and telemetry information at the same time, and the COM servers of multiple server groups share the tasks at the same time, instead of relying on the COM server of a single server group. Similarly, multiple server groups can issue remote control to the RTU.

[0055] In the traditional NK6000 system, the KF6510 device only communicates with the central COM server. When the central COM server collects the power data of the KF6510 device, it is processed by the central SCADA server, and then the real-time power data of all server groups are refreshed. Once the COM server that undertakes the collection function fails, the power data of all server groups cannot be collected.

[0056] The present invention starts all COM servers in the center, the backup center and the three stations. When there are active and standby COM servers, the active and standby COM servers are started at the same time. Only one of the active and standby COM servers is actually collecting data, and the standby one is used as a standby. When each COM server communicates with the KF6510 device, there are two main and standby channels to prevent one channel from being abnormal while the other channel can communicate normally. The channels of each server group correspond to the RTU where the KF6510 device is located. It is equivalent to each server group collecting data from each server group, and each server group does not affect each other. When the KF6510 device has power data to report, the COM servers of each server group collect the data of the corresponding RTU through their own collection channels, and the collected data are sent to their own SCADA servers for processing, so that each server group can normally collect data from the same RTU without affecting each other. Similarly, each server group remotely controls the equipment under the RTU respectively, and issues commands and feedbacks the equipment control results on their own forwarding channels.

[0057] In addition, when the COM server collection service of one of the server groups is abnormal or the SCADA server processing service is abnormal, the power data of the other four server groups can still be collected normally and the remote control operations can also be issued normally.

[0058] A specific technical solution provided by the present invention is:

[0059] A method for independently collecting power data in a rail transit integrated monitoring system comprises the following steps:

[0060] (1) The collection process is deployed on each COM server of each server group, and the processing process is deployed on each SCADA server of each server group.

[0061] In the above steps, by deploying the collection process on each COM server of each server group, it is convenient for each COM server to collect the power data reported by the KF6510 device according to the data management of the management server. By deploying the processing process on each SCADA server of each server group, it is convenient for each SCADA server to process the power data transmitted by the COM server according to the data management of the management server.

[0062] (2) Power data is uploaded through the KF6510 device, and the data server is used as a management server to control other servers. The management server configures multiple server groups that independently collect and process the power data of the KF6510 device in the database of the data server, each of which includes a COM server that collects the power data of the KF6510 device and a SCADA server that processes the power data of the KF6510 device;

[0063] In the above steps, the present invention uses the data server as a management server, and configures the server group that needs to independently collect and process the power data of the KF6510 device in the database of the data server. This configuration is used to configure which server groups of the KF6510 device have the authority to collect and process.

[0064] (3) In the data server, multiple communication groups are configured for the KF6510 device, and each communication group corresponds to a forwarding channel of each server group;

[0065] In the above steps, the forwarding channel is used for independent control. Independent control can be easily achieved by configuring multiple communication groups in the database for the KF6510 device. Each communication group corresponds to the forwarding channel of each server group, that is, each server group (center / backup center / station) corresponds to a communication group for forwarding data, and each communication group has a primary and backup channel for data transmission.

[0066] (4) Through the control of the management server, a COM server with collection authority in a server group collects the power data uploaded by the KF6510 device and sends the received data to the SCADA server with processing authority in the same server group. The COM server collects the uploaded data through the collection channel corresponding to the server group;

[0067] In the above steps, the collection channel is used to independently collect power data. When the KF6510 device reports the collected data, the management server assigns it to the C0M server of the server group with collection authority. The collection program of each server group manages the data according to the data server and sends the received data to the SCADA server of its own group with processing authority.

[0068] (5) The SCADA server that receives the power data analyzes and processes the data and stores it in a real-time database. The server group successfully obtains the real-time power data without being affected by other server groups. The SCADA server also publishes a power data message to the Redis server after analyzing and processing the data, so that it can be forwarded to other systems for backup;

[0069] In the above steps, the SCADA server processes the data and stores it in the real-time database, and also publishes a copy of the data to the Redis server for subsequent forwarding. The real-time database exists in the memory. The real-time database (RTDB-Real Time DataBase) is a branch of the development of the database system. It is a combination of database technology and real-time processing technology. It can directly collect and obtain various data in the operation process of the enterprise in real time, and convert it into public information that is effective for various businesses.

[0070] (6) The data server manages the communication groups of each server group. When one of the server groups performs remote control operation on a device in the KF6510 device, the control command for the remote control operation will be sent to the device through the forwarding channel of the server group, and the control result will be fed back to the SCADA server of the server group through the forwarding channel and the status of the device will be displayed in real time. The server groups do not affect each other's control over the devices in the KF6510 device;

[0071] In the above steps, when each server group needs to send control commands to the devices under the KF6510 device, they will issue commands and feedback results according to their respective communication groups according to the allocation of the data server, and the server groups will not affect each other. In specific implementation, the control commands are sent from the monitoring interface to the SCADA server, then to the COM server, and then to the specific devices under the RTU, and the status of the controlled devices, such as the opening or closing of the switch, is displayed in real time through the monitoring interface of the NK6000 system.

[0072] (7) When the independent acquisition communication of a server group is abnormal, the abnormal server group will send abnormal information to the management server. After receiving the message, the management server will allocate it to other server groups with normal independent acquisition communication. The COM server and SCADA server of the normal server group will collect and process the power data uploaded by the KF6510 device and store it in the real-time database;

[0073] The above steps involve the abnormal handling of independent power data collection. The server group includes COM server and SCADA server, so the independent data collection communication abnormalities mainly include COM server abnormalities and SCADA server abnormalities. Specifically:

[0074] When an abnormality occurs in the COM server that collects power data of the KF6510 device in a server group, the collection process of the abnormal COM server will send abnormal information to the management server. After receiving the message, the management server will assign it to the SCADA server of other server groups with normal COM servers, instructing it to process the power data collected by the COM servers of the same server group and store it in the real-time database, and publish power data messages to the Redis server for forwarding to other systems for backup. At the same time, the NK6000 system will push an alarm message on the monitoring interface to notify the dispatcher to handle the abnormal COM server in time. It can be seen that when the COM service of one of the server groups is abnormal, the power data of the other four server groups can still be collected and processed normally.

[0075] When an abnormality occurs in the SCADA server that processes the power data of the KF6510 device in a server group, the processing process of the abnormal SCADA server will send the abnormal information to the management server. After receiving the message, the management server will assign it to the SCADA server of other server groups with normal SCADA servers, and order it to process the power data collected by the COM server of the same server group and store it in the real-time database, and publish the power data message to the Redis server for forwarding to other systems for backup. At the same time, the NK6000 system will push the alarm information on the monitoring interface to notify the dispatcher to handle the abnormal SCADA server in time. It can be seen that when the SCADA service of one of the server groups is abnormal, the power data of the other four server groups can still be collected and processed normally.

[0076] (8) Task allocation of monitoring data servers. After a server group issues a control command for remote control operation, if the independent control communication of the server group is abnormal, the abnormal server group will send abnormal information to the management server. The management server will control the control command issued by the abnormal server group to be sent to the server group with normal independent control communication, and use the normal server group to issue control commands and receive feedback results;

[0077] The above steps involve the exception handling of remote control under independent control. The server group includes COM server and SCADA server, so the independent control communication exception mainly includes COM server exception and SCADA server exception. Specifically:

[0078] After a server group issues a control command for remote control operation, if the COM server of the server group is abnormal, the process of the abnormal COM server will send abnormal information to the management server, and the management server will control the control command to be sent to the COM server in the normal server group, and use the normal server group to issue control commands and receive feedback results. At the same time, the NK6000 system will push alarm information on the interface to notify the dispatcher to handle the abnormality in time. It can be seen that when the COM server of one server group is abnormal, the remote control operation command can still be issued normally through the other four server groups.

[0079] After a server group issues a control command for remote control operation, if the SCADA server of the server group is abnormal, the process of the abnormal SCADA server will send abnormal information to the management server, and the management server will control the control command to be sent to the SCADA server in the normal server group, and use the normal server group to issue control commands and receive feedback results. At the same time, the NK6000 system will push alarm information on the interface to notify the dispatcher to handle the abnormality in time. It can be seen that when the SCADA server of one server group is abnormal, the remote control operation command can still be issued normally through the other four server groups.

[0080] Among them, the task allocation of collection and processing authority in step (4) is determined according to the data management of the management server. When anomalies occur in steps (7) and (8), the information transmission between the abnormal server and the management server does not use a channel, but uses the inter-process communication mechanism RPC. In this way, when communication is abnormal, the system can send the abnormal collection and control information to the normal server group for processing without affecting the collection data and the issuance of control commands of the abnormal group. Through the allocation control of the management server, it is ensured that each server group can normally receive real-time power data and store it in the Redis server, and it can also ensure that the control commands issued by each server group are smoothly transmitted to the corresponding equipment and receive the execution results of the equipment. Even if an abnormality occurs in the middle, the dispatcher can be notified in time to handle it, which improves the efficiency of dealing with faults.

[0081] This embodiment also discloses a rail transit integrated monitoring system for independently collecting power data, including a NK6000 system and a PSCADA system, wherein the PSCADA system includes a KF6510 device for communication, and the NK6000 system includes a data server and multiple server groups for independently collecting and processing power data of the KF6510 device. Corresponding to one KF6510 device, the multiple server groups in the NK6000 system include one central server group, one backup central server group, and 1-3 station server groups.

[0082] The KF6510 device is used to upload power data;

[0083] The data server is used as a management server to control other servers. The management server configures multiple server groups that independently collect and process the power data of the KF6510 device in the database of the data server. In the data server, multiple communication groups are configured for the KF6510 device, and each communication group corresponds to the forwarding channel of each server group. The task allocation of independently collecting and processing the power data of the KF6510 device and the task allocation of issuing control commands to the equipment of the KF6510 device are determined through the data management of the management server.

[0084] The central server group includes a central COM server for collecting power data of the KF6510 device and a central SCADA server for processing power data of the KF6510 device;

[0085] The backup center server group includes a backup center COM server for collecting power data of the KF6510 device and a backup center SCADA server for processing power data of the KF6510 device;

[0086] The station server group includes a station COM server for collecting power data of the KF6510 device and a station SCADA server for processing the power data of the KF6510 device.

[0087] The rail transit integrated monitoring system that independently collects power data, by implementing the above-mentioned method, can enable the center, backup center and three stations in the NK6000 system to independently collect power data from the KF6510 device, and can also enable the center, backup center and three stations in the NK6000 system to independently issue control commands to the equipment under the KF6510 device, thereby realizing independent control.

[0088] This embodiment also provides a flow chart for collecting power data, such as Figure 6 As shown, the process of collecting power data independently and the process of collecting power data non-independently are involved. The process of collecting power data independently corresponds to the RTU to be collected independently, and the process of collecting power data non-independently corresponds to the RTU that does not need independent collection. In this flowchart, KF6510, KF6510 device and RTU all express the same meaning, server group and group express the same meaning, and the channel involved in the process of collecting power data is the collection channel.

[0089] This embodiment also provides a flow chart of independent control, such as Figure 7 As shown, in the flow chart, KF6510, KF6510 device and RTU all express the same meaning, server group and group express the same meaning, and the channel involved in the independent control process is the forwarding channel.

Upload power data through RTU, use the data server as a management server to control other servers, and the management server configures multiple server groups that independently collect and process the power data of RTU in the database of the data server, each of which includes a collection server that collects the power data of RTU and a processing server that processes the power data of RTU; the RTU adopts the KF6510 device, the collection server adopts the COM server, and the processing server adopts the SCADA server; corresponding to one KF6510 device, the multiple server groups that independently collect and process the power data of the KF6510 device include 1 central server group, 1 backup central server group and 1-3 station server groups, the KF6510 device is a communication device provided in the PSCADA system, and the data server, central server group, backup central server group and station server group are all provided in the NK6000 system; In the data server, multiple communication groups are configured for the KF6510 device, and each communication group corresponds to the forwarding channel of each server group. The data server manages the communication groups of each server group. When one of the server groups remotely controls a device in the KF6510 device, the control command will be sent to the device through the forwarding channel of the server group, and the control result will be fed back to the SCADA server of the server group through the forwarding channel and the status of the device will be displayed in real time. Each server group does not affect the control of the device in the KF6510 device. S2. Through the management and control of the management server, after a collection server with collection authority in a server group collects the power data uploaded by the RTU, it sends the received data to the processing server with processing authority in the same server group. The collection server collects and uploads data through the collection channel corresponding to the server group. When the independent collection communication of a server group is abnormal, the abnormal server group will send abnormal information to the management server. After receiving the message, the management server will allocate it to other server groups with normal independent collection communication. The COM server and SCADA server of the normal server group collect and process the power data uploaded by the KF6510 device and store it in the real-time database. S3. The processing server that receives the power data analyzes and processes the data and stores it in a real-time database.

2. The method for independently collecting power data in a rail transit integrated monitoring system according to claim 1, characterized in that: Before step S1, the collection process is deployed on each COM server of each server group, and the processing process is deployed on each SCADA server of each server group.

3. The method for independently collecting power data in a rail transit integrated monitoring system according to claim 1, characterized in that: After analyzing and processing the data, the SCADA server also publishes power data messages to the Redis server for forwarding to other systems for backup.

4. The method for independently collecting power data in a rail transit integrated monitoring system according to claim 1, characterized in that: After a server group sends a control command for remote control operation, if the independent control communication of the server group is abnormal, the abnormal server group will send abnormal information to the management server. The management server will control the control command issued by the abnormal server group to be sent to the server group with normal independent control communication, and use the normal server group to send control commands and receive feedback results.

5. The method for independently collecting power data in a rail transit integrated monitoring system according to claim 1, characterized in that: After receiving the abnormal information, the management server will push the alarm information to the monitoring interface of the NK6000 system to notify the dispatcher to handle the abnormality in time.
