In the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified.
At present, the existing station integrated monitoring system is generally divided into a monitoring system of a station and a monitoring system of a monitoring control center, the monitoring system of the station monitors and controls equipment in the station through a real-time server in the station, the monitoring system of the monitoring control center monitors and controls equipment of all stations of the whole line through a control server, the control server of the monitoring control center and the real-time server of the station perform data interaction, so that the monitoring and control of the monitoring control center on the station are realized, and data interaction is performed between the station and the station through the monitoring control center. According to the existing scheme, the existing station comprehensive monitoring system adopts a cascaded data deployment mode, data of a monitoring control center is from a real-time server of a station, instructions of the monitoring control center can only be sent to equipment of the station through the real-time server of the station, when the monitoring control center server breaks down, the data of the whole line cannot be uploaded to the monitoring control center, and the monitoring control center loses control over the equipment of the whole line; if the real-time server of the station fails, the monitoring system of the station cannot operate, that is, the data flow of the existing station comprehensive monitoring system is too long, and the reliability is not high because of no fault-tolerant mechanism.
As shown in fig. 1, a monitoring service system provided by the present invention includes: control center and a plurality of control node, every above-mentioned control node all includes: operation station, standby server and front-end processing equipment, above-mentioned control center includes: at least two control servers;
any control server is in communication connection with an operation station and front-end processing equipment in at least one monitoring node, and any standby server is in communication connection with the operation station and the front-end processing equipment in the monitoring node where the standby server is located;
at least one operating station is in communication connection with a standby server in at least one other monitoring node, wherein the operating station and the at least one operating station in the at least one other monitoring node are both in communication connection with the same control server;
the standby server has a first service group;
the control server has a second service group including services that the backup servers in all the monitoring nodes to which the control server is connected have.
Optionally, the monitoring node may be a monitoring system of a station, that is, the monitoring system of a station may be regarded as a monitoring node, and an operation station, a standby server, a front-end processing device, and the like in the station may be regarded as an operation station, a standby server, a front-end processing device, and the like in the monitoring node corresponding to the station.
Optionally, the monitoring control center described herein may monitor and control data and devices of all stations, which is equivalent to a general monitoring center, and the monitoring control center may also be provided with a corresponding control center operating station, and may view the monitoring data through the control center operating station, or may follow a control instruction for devices of each station, which is not limited in this invention.
Optionally, the operation station in the station may be used to monitor the device in the station, and all data monitored by the station may be checked through the operation station. Meanwhile, the operator can issue some control instructions, such as instructions for opening or closing the equipment, through the operation station.
Optionally, the standby server in the station may have a capability of providing all services required by the monitoring system of the station, and may also have historical data of all data points monitored by the station, and when the control server providing services to the station cannot provide services, the standby server in the station may be started, so that the monitoring system of the station can still continue to complete the monitoring task.
Optionally, the front-end processing device in the station may be connected to the external device, and is configured to collect data of the external device or control the external device.
It should be understood that the monitoring system of the station in the existing station integrated monitoring system is connected with the monitoring system of the monitoring control center through the server, resulting in a long data flow. Therefore, the control server of the monitoring control center can be connected with the operation station of the station and the front-end processing equipment, the control server directly provides services for the operation station and the front-end processing equipment, and data of the operation station and the front-end processing equipment can also be directly uploaded to the control server, so that the data flow can be shortened, and the system is more flat.
It should be understood that, since an actual station integrated monitoring system may cover a plurality of stations, each station has a large number of devices to provide services for the server, if a monitoring control center uses one control server to provide services for the devices of all stations, the operation burden of the control server may be too large, and a fault may easily occur. Therefore, a plurality of control servers can be deployed in the monitoring control center, each control server is connected with part of stations and provides services for the equipment in the connected stations, and therefore the operation burden of the control servers can be reduced. Meanwhile, one control server is only connected with part of stations, when the control server fails and cannot provide service, only the connected part of stations can be influenced, monitoring systems of other stations cannot be influenced, and the reliability of the system can be improved to a certain extent. For example, a certain station integrated monitoring system may need to monitor data of four stations, so the station integrated monitoring system may have four monitoring nodes and one monitoring control center, the monitoring control center may be provided with two control servers, each control server may be connected to devices of the two monitoring nodes, that is, one monitoring server is responsible for providing services to devices of the two stations.
Optionally, a plurality of control center operation stations may be deployed in the monitoring control center, and each control center operation station may be connected to all the control servers of the monitoring control center, or to a part of the control servers, which is not limited in this invention. The operator of the monitoring control center can monitor the data of the whole line equipment or issue some control instructions through the control center operation station, which is not limited by the invention.
It should be understood that in practice, the monitoring system of each station may know which data points and control points the monitoring system of the station needs to monitor and control when being established, and some of the data points and control points may be in the station and some may be in other stations. Therefore, the monitoring nodes with the cross-station monitoring relation can be connected to the same control server, and when cross-station data of data points in other monitoring nodes needs to be acquired or cross-station control instructions are issued to control points in other monitoring nodes, scheduling can be carried out through the control server. For example, station a and station B in fig. 1 have the above-mentioned cross-station monitoring relationship, that is, station a may need to monitor data of some data points in station B, station a's operating station a1 and front-end processing device a1 may be connected to control server 1, station B's operating station B1 and front-end processing device B1 are also connected to control server 1, so that station a1 in station a can obtain data in station B through control server 1, and vice versa.
Optionally, because the cross-station monitoring relationship may exist between the stations, in order to avoid that the cross-station monitoring cannot be implemented when the control server connected to the station having the cross-station monitoring relationship fails, a connection may be established between the stations having the cross-station monitoring relationship, for example, the operator a1 of the station a may be connected to the standby server B1 of the station B, and when the control server 1 cannot provide a service, the operator a1 of the station a may directly obtain data that the station a needs to monitor from the standby server B1 of the station B.
It should be understood that the second service group may include: a plurality of types of services such as data service, calculation service, and control service, for example, the station a may need to obtain data of the data point 1 of the station B and control the control point 1 of the station B, and the second service group may include: the present invention is not limited to this, and the present invention includes a storage service for storing data of data point 1 of station B, a data providing service for providing data of data point 1 to station a, a related calculation service, and a control service for communicating station a to control point 1 of station B.
Optionally, the monitoring system of the station generally performs data acquisition and control on related devices, and the front-end processing device described herein is a general description, and may include a data acquisition device, an execution device, or an underlying controller, and the invention is not limited thereto. These front-end processing devices can perform the functions of data collection and control devices, for example, the front-end device a1 can collect the data of the data point 1, and then the control server 1 and the standby server a1 to which the corresponding front-end processing device a1 is connected can provide the corresponding service for storing and reading the data of the data point 1, that is, the second service group of the control server 1 and the first service group of the standby server a1 can include the service for storing the data of the data point 1 and the service for providing the data of the data point 1. Similarly, for the control command, if the operating station a1 of the station a needs to control the control point 2 in the station and the control command may need to be issued to the outside through the front-end processing device a1 of the station a, the control server 1 and the standby server a1 connected to the operating station a1 of the station a may provide the control logic service for the control point 2, that is, the second service group of the control server 1 and the first service group of the standby server a1 connected to the operating station a1 of the station a may include the control logic service of the control point 2, and this may also be the case for cross-station control.
As shown in fig. 2, a monitoring service method provided by the present invention is applied to an operation station in the monitoring service system, and the method includes:
s100, obtaining a task sent by a client;
s200, determining services required by the task from a second service group of a control server in communication connection with the monitoring node where the operation station is located, and splitting the task into at least one task unit corresponding to each determined required service;
s300, judging whether the control server is in a service state, if so, executing S400, otherwise, executing S500, wherein the service state is a state that the control server can normally provide service for the operation station;
s400, the operation station obtains the determined services required by each item from the control server to process the task unit;
s500, the operation station obtains the determined services required by each item from the standby server to process the task unit;
and S600, combining the processing results of the task units and sending the processing results to the client.
It should be understood that the monitoring service method provided by the present invention is applied to the operation station of each monitoring node of the above-mentioned monitoring service system, that is, the operation station of each station.
Alternatively, the client may be an operation station itself of each station, or may be a control server or a standby server connected to the operation station, which is not limited in the present invention. For example, the client of the operator station a1 of the station a may be itself, or may be the control server 1 communicatively connected thereto.
It should be understood that when the client is the operator station a1 itself of the station a, the operator may input some control commands or data reading commands or the like at the operator station a1 of the station a, and after the operator station a1 obtains the commands, the subsequent steps in the embodiment may be performed.
It should be understood that, when the client is the control server 1 connected to the operating station a1 of the station a, the task sent by the control service 1 may be a task issued by an operator or a pre-program through the control center operating station of the monitoring control center, a task sent by an operating station of another station connected to the control server, or a task sent by a pre-program built in the control server in advance, which is not limited in this embodiment of the invention.
Alternatively, the second service group of the control server may include all services of the standby servers of all monitoring nodes connected thereto. For example, the control server 1 may have connected to it a backup server a1 and a backup server B1, which may be located in different stations, i.e. in different monitoring nodes, and the second service group of the control server 1 may be the sum of the services provided by the backup server a1 and the services provided by the backup server B1, i.e. the control server 1 may provide all the services of both the backup server a1 and the backup server B1.
It should be understood that the second service group of each control server may be the same or different, since the backup server to which each control server is connected may be different, and accordingly, the services included in the second service group may also be different, which is not limited by the present invention.
Optionally, the operation station in the monitoring node connected to the control server may store the second service group in a local storage in a form of a list, so that after the operation station in the monitoring node obtains a task, the obtained task may be split into different task units, that is, different subtasks, according to the list of the second service group stored in the local storage in advance, and one task unit may correspond to a service included in one second service group. The task unit may be device-based, for example, the task completed by the front-end processing device a1 may be regarded as the task unit a1, and when the obtained task includes a task that can be completed by the front-end processing device a1, the task may be split to include the task unit a 1.
It should be understood that the role of task splitting is to make the control server know to which devices the obtained task should be handed to for completion, so as to facilitate subsequent distribution of task units to the respective devices for completion.
Optionally, the relationship between these task units may be discrete, that is, the execution order of these task units may not have a precedence relationship. Of course, the relationship between these task units may be continuous, that is, there is a sequential execution order between the task units, and for such a sequential task unit, the task units may be distributed to different devices for execution in a time-sharing manner according to the sequential relationship between the task units. For example, the task unit a1 is first sent to the front-end processing device a1, and after receiving the result of executing the task unit a1 fed back by the front-end processing device a1, the task unit a2 is sent to other devices, such as the front-end processing device B1, and so on. Of course, the task units with the precedence order may also be distributed to the corresponding devices at the same time, and after the processing results corresponding to each task unit are obtained, the processing results are merged according to the precedence order of the task units and fed back to the client, which is not limited in the present invention.
Optionally, the service information of the second service group may also be stored in other forms, so that the operation station in the monitoring node may split the task according to the service information of the second service, which is not limited in the present invention.
Alternatively, the list of the second service group may be a list in which services included in the second service group are divided and arranged according to stations and specialties. For example, the first block of the list may be a service list of station a, and the first block of the list may be divided into different areas according to different functions, which is not limited by the present invention. Since the list is divided and arranged according to the station and the specialty, splitting the task according to the list of the second service group is also divided according to the station and the specialty, which is not limited by the present invention.
Optionally, the operation station obtains the determined services required by each item from the control server to process the task unit, where the operation station obtains all the determined services required by each item from the control server, and one service may correspond to one task unit, and the obtained service may process and complete the corresponding task unit. For example, the operator station a1 may obtain services that the control server 1 provides data for obtaining data point 1 and control point 1 to 0, obtain service that provides data for data point 1 may represent that the operator station a1 obtains data for data point 1 through the control server 1, and obtain control point 1 to 0 service may represent that the operator station a1 sets control point 1 to 0 through the control server 1, thereby processing a task unit that sets control point 1 to 0.
Optionally, the control server being in the service state may refer to a state where the control server itself has no fault and can provide a service normally, and a communication link between the control server and the connected operation station is normal and can communicate normally.
Optionally, the relationship between the results processed by each task unit may be discrete and has no precedence relationship, and at this time, the corresponding relationship between the processing result and the task unit may be retained, that is, the processing result indicates which task unit the processing result is, and then all the processing results are merged and fed back to the client. The relationship between the processing results of the task units may also be continuous, that is, the processing results have a sequence, and the processing results may be merged according to the execution sequence of each task unit corresponding to each processing result and fed back to the client.
Optionally, in some optional embodiments, the determining whether the control server is in a service state includes:
periodically reading the state mark of the control server;
if the times of successfully reading the state marks in the preset time length before the current time are more than the preset times and the state marks successfully read in the preset time length before the current time are all online marks, determining that the control server is in a service state;
otherwise, determining that the control server is not in a service state.
Optionally, whether the control server is in the service state or not may be determined periodically, that is, the state of the control server is continuously monitored, so that it can be found that the control server cannot provide the service in time, and a corresponding standby server is started in time to replace the control server, so as to continue providing the service for each monitoring node, thereby avoiding an interruption situation in the monitoring process.
Optionally, each control server may have a status flag, where the status flag may be a data bit, and the data bit may represent an online identifier when the data bit is "1" and represent an offline identifier when the data bit is "0", or the other way around, or other feasible flags may be used to distinguish the control servers in the online status and the offline status, which is not limited in this disclosure.
Optionally, the operating station connected to the control server may periodically read the status flag of the control server, and if the operating station successfully reads the status flag a certain number of times within a preset time period, it may be stated that the communication between the operating station and the control server is normal, and there is no fault of delay or communication interruption. If the read state marks are all online identifications, it can be shown that the control server has no fault and can normally provide service. In summary, the control server itself has no failure and the communication with the operation station is normal, i.e. the control server is considered to be in the service state.
Whether the communication is normal and the control server is normal are respectively judged, the condition that the control server cannot provide service can be timely and effectively found, so that the standby server can be started in time to provide service, and the method is reliable.
Optionally, in some optional embodiments, the obtaining, by the operation station, the determined services required by the items from the standby server to process the task unit includes:
