Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

The state information updating system of the present disclosure includes a client and a server, wherein,

In one embodiment, the system further comprises a database, wherein,

In one embodiment, the system further comprises a cache,

Fig. 1 is a schematic diagram illustrating an architecture of a condition monitoring system according to an embodiment of the present disclosure. The components of the condition monitoring system are described below with reference to fig. 1. As shown in fig. 1, the server 10 and the client 11, the DataBase (DB) 12 and the cache 13 connected thereto constitute a status monitoring system according to the present disclosure.

The server 10 may be a server of an FMB (Factory Monitoring Board) platform, the client 11 may be operated in a terminal device used by a user such as a field worker, an operation and maintenance person or a manager, and the user may log in the FMB platform through the client to monitor a device state of a target device on a production field. The server 10 may include a plurality of functional modules, such as a message receiving module 101, a message reading module 102, a timed task module 103, and an information query module 104, and specific functions of each module may be referred to in the following embodiments, which are not described herein again. The terminal device may be a mobile phone, a tablet device, a notebook computer, a Personal Digital Assistants (PDAs), a wearable device (such as smart glasses, a smart watch, and the like), a VR (Virtual Reality) device, an AR (Augmented Reality) device, and the like, which is not limited by the present disclosure. The application program of the client can be pre-installed on the terminal equipment, so that the client can be started and run on the terminal equipment; of course, an online "client" such as HTML5 technology may also be used, which is obtained and run without installing a corresponding application on the terminal device.

The server 10 is further connected with a Manufacturing Execution System (MES) 14 as a production information management System facing the Manufacturing enterprise workshop Execution layer through a message queue 15, and the System is connected with production equipment 16 in the production environment. The system may be composed of multiple execution units, such as MES x and MES y as shown in the figure, where the multiple execution units may respectively correspond to different equipment objects, different production lines, or different workshops in the production environment, for example, MES x and MES y may respectively correspond to a workshop 1 and a workshop 2, or may also respectively correspond to a production line 1 and a production line 2 in a certain workshop, and details are not repeated. The target device in the present disclosure may be any production device to which the manufacturing execution system 14 is connected. The message queue 15 for connecting the manufacturing execution system and the service end 10 may be a message middleware TIB Rendezvous, or Kafka, RabbitMQ, ActiveMQ, or the like, which is not limited by the embodiment of the disclosure.

The manufacturing execution system 14 may also be coupled to a database 12, which may be a local storage space or an external storage space of the manufacturing execution system 14, for storing production data, real equipment status, etc. generated by the manufacturing execution system 14 during operation. In fact, the device information of any one device stored in the database 12 can be divided into two categories: the device information comprises device basic information and device state information, wherein the device basic information can comprise a device name, a device identifier, interface information, an installation position, a function, a brand, a size and the like; the device status information may include whether the device is working (on or off), temperature, pressure, rotation speed, valve opening size, and the like, which is not described in detail.

The cache 13 is configured to store a state change message of any device received by the server 10 or modified state information of the device extracted according to the state change message. Specifically, the cache may be a Remote Dictionary Server (Redis), which is an efficient storage system based on a memory and can enable the cache 13 to have higher data caching efficiency.

The operation of the condition monitoring system will be briefly described below. The manufacturing execution system 14 may be connected to not only the production equipment 16, but also detection equipment cooperating with each production equipment, such as actuators, such as an electronic switch and an electromagnetic valve, and sensors, such as a thermometer, a pressure gauge, and a flow meter, so that the manufacturing execution system 14 may sense the equipment status of each production equipment in real time through the detection equipment. Under the condition that a change (such as a device start or a device shutdown, a switch opening or closing, a temperature increase or decrease, a flow increase or decrease, or the like) of a device state of a target device (which may be any production device) is sensed, the manufacturing execution system 14 may update the device state information of the target device recorded in the database 12 according to the change, so that the device state information of the target device is stored in the database 12 in real time — because the manufacturing execution system 14 updates the device state information stored in the database 12 in time, the device state information of the target device read from the database 12 at any time can be used to represent a real device state of the target device at the time.

Based on this, in the case of receiving a status monitoring request initiated by the client 11 for the target device, the server 10 may read device status information of the target device at the current time from the database 12, and return the device status information as current status information of the target device to the client 11 for being displayed in the target monitoring interface. As can be seen, the current state information described in the embodiment of the present disclosure is the device state information of the target device read from the database 12 by the server 10 in response to the state monitoring request initiated by the client 11. In addition, in the case of receiving the status monitoring request, the server 10 may determine that the client 11 has a status monitoring requirement for the target device, and at this time, the server 10 may register a message obtaining service for the target device with the message queue 15, so as to obtain a status change message for the target device from the message queue 15; of course, the server 10 may not register the service, but check the messages in the message queue 15 to obtain the status change message for the target device.

After returning the current state information to the client 11, if a state change message for the target device is received again, the server 10 may directly send the changed state information included in the message to the client 11; or, the message or the changed state information may be stored in the cache 13, and sent to the client 11 according to a fixed period or returned to the client 11 in response to an update query request initiated by the client 11, so that the client 11 updates the target monitoring interface by using the changed state information. The receiving process of the state change message may be executed by the message receiving module 101, and the reading and sending process of the changed state information may be executed by the message reading module 102. The timed task module 103 may be configured to manage execution frequencies of various timed tasks in the state monitoring system, where the timed task may include a message reading task executed by the message reading module 102 and an information query task executed by the task querying module 104. The message reading task is to read the stored state change message or the changed state information from the cache 13 according to the fixed period, and the information querying task is to read whether the basic information such as the target layout file of the target device from the database 12 according to the fixed period changes, and the related processing of the target layout file may refer to the description of the subsequent embodiments, which is not repeated here. Wherein, the fixed period of the message reading task should be less than the fixed period of the information query task.

As can be seen from the above description of the state monitoring system, the current state information displayed in the target monitoring interface by the client is used to represent the state of the target device before the change, and the updated target monitoring interface according to the changed state information is used to represent the new state of the device after the change. Through the scheme, a user can know whether the target equipment is changed and what kind of change occurs through the target monitoring interface without going to the production environment on-site checking, so that the labor cost is saved, the interference of personnel to the production environment is effectively avoided, the adverse effect on the cleanliness of the production environment is avoided, and the product quality is ensured.

The following describes in detail a scheme for updating status information implemented based on the foregoing status monitoring system with reference to fig. 2 to 4 and corresponding embodiments thereof, respectively.

Fig. 2 is a flowchart illustrating a method for updating status information according to an embodiment of the present disclosure. As shown in fig. 2, the method is applied to a server of a condition monitoring system, and the method may include the following

steps

202 and 204.

Step 202, in response to a status monitoring request initiated by a client for a target device, returning current status information of the target device to the client, so that the client displays the current status information in a target monitoring interface.

Before logging in the client, the user needs to register a user account of the user at the server. In order to realize effective control of the production process, the server can create (i.e., register) different types of user accounts for different users according to the roles played by the users in the production process, and respectively allocate corresponding account permissions to various accounts. For example, the user account registered in the server may include at least one of: an administrator account, an operation and maintenance account, a general account, a plan account, etc. The operation and maintenance personnel corresponding to the operation and maintenance account can have the authorities of equipment monitoring, machine management, group management, billboard directory query and the like; a common production worker corresponding to the common account can have the authority of equipment monitoring, bulletin board directory query, fault reporting and the like of equipment corresponding to a working post of the worker; production planning personnel corresponding to the planning account can have the scheduling planning authority; and the administrator user corresponding to the administrator account can have all operation authorities for the state monitoring system, such as system setting authority, group management authority, state dictionary query authority, physical position management authority and the like. Of course, the specific permissions of different accounts may be reasonably set according to actual production scenarios, which is not limited in the embodiment of the present disclosure. Based on this, the server may maintain a user authority list, where the list is used to record the authority owned by the user corresponding to each user account that has completed registration.

After the user logs in the user account in the client, the client may determine the target device according to default settings, for example, determining the device monitored by the user last time as the target device or determining the device which has recently changed as the target device; alternatively, the user may designate a certain device to the client through a device selection operation, and the client may determine the device as the target device in response to the operation. It can be understood that the target device determined in the above manner is the monitoring object of the client at the current time, so that the client may initiate a state monitoring request for the target device to the server.

For a server, a status monitoring request sent by any client received by the server may include identity information of a user who logs in the client, such as a user account, an account nickname, and the like that the client logs in. The server may determine, according to the identity information, whether the user account corresponding to the user has the monitoring right for the target device, for example, the right owned by the user account is queried in the user right list. Furthermore, under the condition that the identity information indicates that the user does not have the monitoring authority for the target device, the server side can refuse to return the current state information of the target device to the server side, so that the user is prevented from monitoring the target device in an overrun mode. In addition, the server may also discard the status monitoring request, or return a reminding message to the client, so that the client can remind the user, or send an alarm message, or even temporarily freeze some rights of the user, and the like, which is not described again. By the method, the server side can only return the current state information of the equipment to the client side used by the user with the monitoring authority aiming at the target equipment, so that the monitoring authority of the equipment is effectively controlled, and potential safety hazards possibly brought by overrun monitoring are avoided.

As described above, the manufacturing execution system in the status monitoring system may update the status information of the target device recorded in the database associated with the manufacturing execution system itself in response to the status information of the target device being changed, so that the database always records the latest status information of the target device. Based on this, under the condition that the state monitoring request initiated by the client is received or the user is determined to have the monitoring authority for the target device, the server can read the state information of the target device from the database, and return the information to the client as the current state information of the target device, so that the client displays the information in the target monitoring interface.

Any production equipment in the production environment is usually connected to other equipment according to a certain layout mode (i.e. equipment layout), and the equipment layout is usually recorded in a layout file corresponding to the production equipment. For example, the target layout file corresponding to the target device may be used to indicate a device layout of the target device, such as a device hierarchy to which the target device belongs, an installation location of the target device, a connection manner between the target device and another device, and the like. The layout file of each device may be stored locally at the server or in the database, and specifically, the corresponding layout file may be stored as an index according to the identification information (e.g., device ID) of the device, so as to query the layout file of the device according to the identification information of the device.

Based on this, in order to improve the readability of the current state information, the server may return the target layout file corresponding to the target device to the client, so that the client can display the current state information in the target monitoring interface according to the device layout of the target device indicated by the target layout file. For example, the server may query a target layout file corresponding to the target device according to the identification information included in the status monitoring request, and return the target layout file to the client, so that the client displays the current status information according to the device layout indicated by the target layout file. Wherein the target layout file can be returned to the client in association with the current state information. Correspondingly, under the condition that the client receives the target layout file and the current state information, the client can determine the equipment layout of the target equipment indicated by the client through analyzing the target layout file, and display the current state information in the target monitoring interface according to the equipment layout. Specifically, the client may determine the shape information, size, orientation, and the like of the target device by analyzing the target layout file, so as to draw a device graph representing the target device in the target monitoring interface according to the external information, and then display the current state information of the target device at a corresponding position of the device graph.

As can be seen, the target layout file may be regarded as a "drawing" of the target device. The target layout file of the target device of the present disclosure may be a Graphics file (hereinafter referred to as SVG file) in SVG (Scalable Vector Graphics) format. The SVG file is a graphic file based on XML (Extensible Markup Language), and can be clearly and undistorted displayed on a screen with any resolution, so that the client can display clear and undistorted device graphics by using the SCG file as a target layout file of the target device, thereby ensuring the display accuracy of the current state information.

It can be understood that the device layout of the target device may be changed, and to ensure the accuracy of displaying the current state information, the server may periodically check whether the target layout file is changed, and send the changed target layout file to the client under the changed condition, so that the server can display the current state information according to the changed target layout file in time. For example, the timed task module 103 shown in fig. 1 may configure the information query module 104 to execute the information query task according to a fixed period, such as checking whether the target layout file stored in the database 12 is changed according to the period. Of course, considering that the device layout of the target device is not frequently changed in the production process, the fixed period may be set to be appropriately longer, such as 12 hours, 1 day, 1 month, 1 week, and the like, and the embodiment of the disclosure does not limit this.

The target layout file obtained by the server may include at least one layout file, any layout file may include at least one file element, and any file element may correspond to multiple real devices in the production environment, that is, the file element may be reused by multiple real devices. The file element may be a basic unit or a combination of multiple basic units that constitute the layout file, and any file element may correspond to a certain device or a certain functional module in the device. For example, device 1 and device 2 are two devices of the same model deployed in different workshops, and the device layouts are the same and the device identifications are different — obviously, device 1 and device 2 correspond to the same file element S in the same layout file. In the case that the target device is the device 1, which is determined in the foregoing manner, if the client displays the element identifier of the file element S in the target monitoring interface, the user may not be able to distinguish whether the identifier is used to represent the device 1 or the device 2 in the production environment, and thus cannot determine whether the current state information of the device 1 or the current state information of the device 2 is correspondingly displayed in the target monitoring interface.

In order to avoid confusion of display and understanding, after the server side obtains the target layout file, the server side can determine the target elements corresponding to the target equipment in the file, replace the element identifiers of the target elements recorded in the target layout file with the equipment identifiers of the target equipment, and then return the replaced target layout file to the client side. It can be understood that, in the case of obtaining the replaced target layout file, the client may draw an equipment graph of the target equipment in the target monitoring interface according to the external information obtained by parsing the file, and then display the equipment identifier of the target equipment and the current state information of the target equipment at a corresponding position of the equipment graph. If the device identifier (instead of the element identifier of the file element S) of the device 1 can be displayed on the device graph, the user can visually check the current state information of the target device, so that the understanding barrier is avoided, and the smooth operation of the production process and the state monitoring is favorably ensured.

And 204, under the condition that a state change message for the target equipment is received, sending changed state information, contained in the state change message, of the target equipment after the change to the client, so that the client updates the target monitoring interface according to the changed state information.

After the current state information is returned to the client for display, the server may receive a state change message for the target device sent by the manufacturing execution system, where the message includes changed state information of the target device after the change. Then, the server may send the message to the client, so that the client updates the target monitoring interface according to the message, that is, the changed state information is displayed in the target monitoring interface. In a case that the current state information is displayed by the server according to the device layout indicated by the target layout file, the changed state information may also be displayed by the server according to the device layout, and thus, the target layout file of the target device may be used to display the device information (the current state information and the changed state information) of the target device.

The server side can send the changed state information to the client side in various modes. In an embodiment, in order to improve the real-time performance of the device information displayed by the client as much as possible, the server may extract the changed state information from the received state change message and directly send the information to the client, so that the client can display the changed state information to the user as soon as possible, and errors possibly caused by display delay are avoided.

In another embodiment, since the target device may be changed several times in a short time and the user does not need to check the changed state information after each change, the server may write the changed state information in the state change message into the cache and read the changed state information from the cache at an appropriate time to send the changed state information to the client. For example, when a status change message for the target device is received, the server may write the changed status information included in the message to the cache. The server side can write the changed state information into the cache according to a preset format. For example, for a target device including 10 state parameters, the server may sequentially write the four state parameters into the cache according to a preset sequence at a storage address corresponding to the target device under the condition that the changed state information includes 1 st to 4 th state parameters. For example, the changed state information may be written in a key _ value key value pair, such as { key ═ device ID; value is temperature 1/pressure 1/temperature 2/flow 1/rotation speed 1/pressure 2/rotation speed 3, and will not be described in detail.

In addition, under the condition that the state information of the target device is not written in the cache, the server side can write the changed state information in a blank address of the cache; and under the condition that the state information of the target equipment is written in the cache, the server side can use the changed state information to cover the written state information, so that the occupation of the cache space by the changed state information and the data volume required to be sent to the client side are reduced.

After that, the server may send the changed state information stored in the cache to the client according to a fixed period. For example, in any cycle, if the server receives the first data change message for the target device, the state information after the change contained in the message may be written into the cache; if a second status change message for the same target device is received in the period, the changed status information (contained in the first status change message) written in the cache may be overwritten by the changed status information in the second status change message. The fixed period may be set according to an actual situation, for example, may be 1s, 50ms, 2s, 10s, and the like, and the fixed period may be smaller than a check period of whether the server updates the target layout file.

By the method, the server can use the changed state information of the next state change message to cover the changed state information of the previous state change message, the changed state information of any equipment is ensured to occupy a fixed storage space in the cache, and the cache space can be effectively controlled even if the state change messages are increased rapidly. Of course, at the end of the current period, the server may send the changed state information (the state information changed the last time from the current time) recorded in each cache to the client for display, and trigger the process of starting the state change message reception of the next period and writing the changed state information into the cache.

Or, the server may also write the changed state information into the cache in the data overlay manner, and return the changed state information recorded in the cache to the client in response to an update query request initiated by the client. By the method, the server returns the changed state information to the client only when the client needs the changed state information, so that the data volume of the changed state information sent to the client by the server is further reduced. Through the data coverage mode, the number of the changed state information needing to be displayed by the client can be reduced, namely the workload of the client for updating the target monitoring interface is reduced, the client is helped to avoid the faults of delay or blockage and the like, and therefore the user experience of checking the changed state information by the user is guaranteed.

In addition, after reading the changed state information of any device written in the cache, the server may delete the data from the cache, or set a failure flag for the data, so as to recycle the corresponding storage space, thereby implementing efficient utilization of the cache.

Fig. 3 is a flowchart illustrating another status information updating method according to an embodiment of the present disclosure. As shown in fig. 3, the method is applied to a client of a condition monitoring system, and the method may include

steps

302 and 304 described below.

Step 302, in response to a status monitoring operation performed by a user for a target device, initiating a status monitoring request for the target device to a server, and displaying current status information of the target device returned by the server in response to the request in a target monitoring interface.

As described above, the status monitoring request sent by the client to the server may include the identification information of the device, so that the server may query the target layout file corresponding to the target device according to the identification information and return the file to the client. At this time, the client may display the current state information in the target monitoring interface according to the device layout indicated by the target layout file. For example, the client may parse the target layout file to obtain external information, draw a device graph of the target device in the target monitoring interface according to the information, and then pertinently display the current state information at a corresponding position of the graph.

Wherein the device layout indicated by the target layout file may include at least one of: the device level to which the target device belongs, the installation position of the target device, and the connection mode between the target device and other devices.

As shown in fig. 4, function options such as "device monitoring", "device management", "device grouping", "statistics management", and "system management" are displayed in a menu bar 401 at the top of the interface, and when "device monitoring" is triggered, a tree structure frame 402, a graphic display frame 403, and an information display frame 404 may be displayed below.

In the tree structure frame 402 on the lower left side, options of different levels such as "type", "factory", and "group" are included, and when the "type" option is triggered, equipment types such as "vacuum pump", "cutter", and "granulator" are further displayed according to the equipment types, and a cyclone "CLT 4" is displayed according to the equipment identification. The status indicator 4021 may be displayed in front of the CLT4, so as to visually indicate the current status of the device, such as the current status being in an operating state or a shutdown state, and the size, shape, color, and other display parameters of the status indicator 4021 may be set by default or by user, so that the user can understand what they refer to.

The device graphics of the currently selected target device CLT4 can be displayed in the graphic display box 403 in the middle of the lower part, and the shape, color, texture, line and other target display parameters of the graphics can be used for representing the state information of the CLT 4. The information display frame 404 on the lower right side may display device information of the target device CLT4, such as the aforementioned device basic information, status information after aggregation, and the like, which is not described again.

Step 304, in the case of receiving the changed state information of the target device sent by the server, updating the target monitoring interface according to the changed state information.

It can be understood that the process of updating the target monitoring interface by the client according to the changed state information is a process of updating the current state information displayed in the target monitoring interface to the newly received changed state information. For example, in the scenario shown in fig. 1, when the client receives the changed state information sent by the server, the client may update the target display parameters such as the shape, color, texture, and line of the device graphic shown in the graphic display box 403 according to the information, and/or may also update the state information shown in the information display box 404, and the specific update manner of the target monitoring interface is not limited in the embodiment of the present disclosure.

Through the embodiment, the client can respond to the state monitoring operation carried out by the user for the target equipment, and initiate the state monitoring request for the equipment to the server. The server side can respond to the request and return the current state information of the equipment to the client side, so that the client side can display the current state information in the target monitoring interface. Further, when receiving a state change message for the target device, the server may send changed state information, included in the message, of the target device to the client, so that the client updates the target monitoring interface according to the changed state information.

Actually, the user may also perform corresponding management operations on the target monitoring interface, which is described below with reference to fig. 4.

In an embodiment, when the current status information or the changed status information is displayed in the target monitoring interface, the user may perform a status refreshing operation in the interface, for example, may click a shortcut key or perform the status refreshing operation in a right-click menu in the graphic display frame 403 shown in fig. 1. Thus, the client may initiate an update query request for the target device CLT4 to the server in response to this operation, so that the server returns the latest changed state information in response to this request. As can be seen from the foregoing embodiments, the changed state information returned by the server may be the changed state information of the target device read from the cache. Correspondingly, the client can further update the target monitoring interface after receiving the changed state information so as to display the information in the interface.

Of course, in the case of receiving the update query request initiated by the client, the server may check whether the changed state information of the target device is already stored in the cache: if the information is not stored, the information indicates that the target equipment is not changed in a period of time from the time of the last change to the current time, and at this time, empty information or other preset special information can be returned naturally without returning changed state information to the server; if the information is stored, the target device is indicated to be changed at least once in the period of time, and the changed state information stored at the moment is changed state information after the last change, and at the moment, the information can be read from the cache and sent to the client.

In an embodiment, in addition to viewing the status information of the target device in the target monitoring interface, the user may also view the status information of other devices. For example, the user may perform a first switching operation in the target monitoring interface (e.g., triggering the "device group" function option in the menu bar 401 shown in fig. 4), and the client may determine its corresponding switched interface in response to the operation. The switched interface may be a centralized monitoring interface, the interface is used for centrally displaying status information of each device in the device set corresponding to the operation, and the switched device corresponding to the interface is each device in the device set. The device set may be a "type", "factory", "group", or other form of device set, and this is not limited by the embodiments of the present disclosure. Or, the interface after switching may also be a monitoring interface of any device, where the interface may be used to display status information of any device, and the device after switching corresponding to the interface is the any device.

Further, the client may initiate an update query request for the switched device corresponding to the switched interface to the server, and display, in the switched interface, changed state information of the switched device returned by the server in response to the request. It can be understood that, in the case that the switched interface is a centralized monitoring interface, the user can perform batch and centralized monitoring on each device in the device set, thereby improving the monitoring efficiency; and under the condition that the interface after switching is the monitoring interface of any equipment, the user can monitor the state of the equipment in a targeted manner.

In one embodiment, to manage the presentation of the status information, the user may configure the corresponding display parameters. For example, the user may implement a real-time second switching operation to switch the target monitoring interface to a parameter configuration interface. As shown in fig. 4, the user may trigger a "system management" function option in the menu bar 401, so that the control client jumps from the target monitoring interface shown in fig. 4 to a parameter configuration interface (not shown). Furthermore, the user can implement a parameter configuration operation in the parameter configuration interface, and the client can perform corresponding configuration on the display parameters in response to the operation. The parameter configuration operation is to change the display parameters of the shape, color, texture, lines and the like of a certain state, for example, the downtime state is changed from black to gray, and the rotating part is changed from a circle to a sector, and the like. The configured display parameters may be used to display status information of the corresponding device in the target monitoring interface and/or the monitoring interfaces of other devices.

It should be noted that, if the user performing the parameter configuration operation is an administrator user, the client may send the configured display parameter to the server, and send the configured display parameter to the client of another user (such as an ordinary user) corresponding to the user by the server. Therefore, the client sides of other users can display the equipment information in the target monitoring interface according to the configured display parameters. By the mode, the administrator user can realize the uniform configuration and change of the display parameters, and the configuration efficiency is improved. And under the condition that the user implementing the parameter configuration operation is a common user, the client can store the configured display parameters locally, and then the device information can be displayed in the target monitoring interface according to the configured display parameters. Through the mode, a common user can configure the display parameters in a user-defined mode, so that the display effect of the equipment information accords with the viewing habit of the user.

In an embodiment, a user may view the operational metrics of the target device. For example, the user may perform a metric viewing operation in the target monitoring interface, such as triggering a "statistics management" function option in menu bar 401 shown in FIG. 1. The client can respond to the operation and count the operation index of the equipment according to the equipment state of the target equipment; or obtaining the operation index of the target equipment from the server, wherein the operation index is obtained by the server according to the equipment state statistics of the target equipment. Furthermore, the client can display the operation index in a switched interface corresponding to the index viewing operation. The switched interface may be the target monitoring interface, or may also be an index statistical page skipped from the target monitoring interface, or the like; the statistical index may be an activation rate (i.e., a proportion of time occupied by the equipment to create value in the time that can be provided), a state percentage statistic, an equipment history, a product history, and the like within a preset time period, which is not limited in the embodiment of the present disclosure. Through the method, the client can show the statistical indexes of the target equipment to the user, so that the overall working condition of the target equipment can be conveniently, conveniently and quickly obtained.
