Description

Technical Field

[0001] The present application relates to the field of communications, and in particular, to a control method and device for link diagnosis, a storage medium, and an electronic device. Background Art

[0002] On the one hand, the industrial data acquisition and supervisory control (SCADA) system usually uses a large number of master-slave serial field buses when communicating with equipment. The front-end communication processor (Front-End Processor, FEP) as the upper computer of equipment communication often adopts redundant configuration, that is, the FEP performs another machine link diagnosis operation, which will cause the redundant master station link conflict mode problem. That is, at the same time, the FEP as a redundant master station cannot initiate requests to the equipment at the same time. The redundant FEP master stations must coordinate to send device requests, otherwise it will cause bus conflicts.

[0003] Normally, the way in which the redundant FEP master stations coordinate to send device requests (i.e., another machine link diagnostic operation) is usually as follows: among the redundant FEPs, one FEP is selected as the actual master (Hot) FEP, and the other FEP is selected as the actual standby (Standby) FEP. The actual master FEP is the main initiator of the device request. Most of the time, only the actual master FEP will send requests to the device. The actual standby FEP has the right to initiate requests to the device only when the diagnostic cycle (for example, every 30 seconds) is reached (when the actual standby FEP has the right to initiate requests to the device, the actual master FEP will suspend initiating requests to the device).

[0004] On the other hand, industrial SCADA systems usually require remote control of equipment through a human-machine interface (HMI) to remotely control equipment or adjust equipment parameters.

[0005] In the prior art, the remote control of the HMI and the link diagnosis of the FEP are independent of each other and have no operational association. The link diagnosis of the FEP is usually executed periodically. When executing the remote control operation of the HMI, the link diagnosis of the FEP may be encountered, which will reduce the efficiency of the remote control operation.

[0006] When performing remote control operation through the HMI, there may be a problem that the FEP's other machine link diagnosis may occur, resulting in a decrease in the efficiency of the remote control operation. No effective solution has been proposed yet.

[0007] Therefore, it is necessary to improve the related technology to overcome the above-mentioned defects in the related technology. Summary of the invention

[0014] In an exemplary embodiment, after the state of the front-end processor of the controlled network device is adjusted to a remote control ready state, the method further includes: determining whether the link diagnosis of the other machine is being executed when a control instruction sent by the remote control device is received; and determining whether a complete response information sent by the diagnosed device is received when it is determined that the link diagnosis of the other machine is being executed, wherein, in the process of executing the link diagnosis of the other machine, the front-end processor sends a diagnostic link request to each diagnosed device respectively, so as to determine the link information between the front-end processor and each diagnosed device respectively according to the complete response information sent by each diagnosed device; and suspending the execution of the link diagnosis of the other machine and sending the control instruction to the controlled network device when it is determined that the complete response information sent by the diagnosed device is received.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] It should be noted that the terms and "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] The method embodiments provided in the embodiments of the present application can be executed in the front-end processor of the controlled network device or a similar computing device. Taking the front-end processor of the controlled network device as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a front-end processor of a controlled network device in a link diagnosis control method according to an embodiment of the present application. Figure 1 As shown, the front-end of the controlled network device may include one or more ( Figure 1Only one is shown in the figure) processor 102 (processor 102 may include but is not limited to a microprocessor (Microprocessor Unit, referred to as MPU) or a programmable logic device (Programmable logic device, referred to as PLD)) and a memory 104 for storing data. In an exemplary embodiment, the front-end of the above-mentioned controlled network device may also include a transmission device 106 and an input and output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is for illustration only and does not limit the structure of the front-end processor of the controlled network device. Figure 1 More or fewer components as shown, or with Figure 1 Equivalent functions or comparisons shown Figure 1 A different configuration with more features is shown.

[0028] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the control method of link diagnosis in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, which is equivalent to implementing the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the ball machine via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0029] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of a front-end of the controlled network device. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0030] In this embodiment, a link diagnosis control method is provided, which is applied to Figure 1 In the front-end of the controlled network device, Figure 2 : is a flow chart of a control method for link diagnosis according to an embodiment of the present application, the flow includes the following steps:

[0031] Step S202, receiving an activation command sent by the remote control device when the remote control device performs a first operation, wherein the first operation includes at least one of the following: the remote control device displays the program control interface for a time period greater than or equal to a first preset time period, and the remote control device receives a target operation of a target object to select program control card information of the controlled network device in the program control interface; wherein the target operation is used to indicate the target object;

[0032] Step S204, in response to the activation command, determining that the remote control device is to perform a remote control operation, and adjusting the state of the front end processor to a remote control ready state, wherein when the state of the front end processor is the remote control ready state, pausing the front end processor from performing another machine link diagnosis.

[0033] That is to say, upon receiving an activation command sent by the remote control device, i.e., determining that the remote control device is about to perform a remote control operation, the front-end processor needs to suspend executing the other-machine link diagnosis operation to avoid a conflict between the front-end processor's execution of the other-machine link diagnosis and the remote control operation, thereby affecting the efficiency of control.

[0034] Through the above steps, when the remote control device displays the program control interface for a time period greater than or equal to the first preset time period, or the remote control device receives an operation in which the target object selects the program control card information of the controlled network device in the program control interface, etc., the activation command sent by the remote control device is received; the front-end processor of the controlled network device responds to the activation command, determines that the remote control device is to perform a remote control operation, and adjusts the state of the front-end processor to a remote control ready state to suspend the front-end processor from performing another machine link diagnosis. In other words, when receiving the activation command sent by the remote control device, the front-end processor of the controlled device is controlled to prohibit the execution of another machine link diagnosis. Through the above technical solution, the problem that when performing remote control operation through HMI, the other machine link diagnosis of FEP may be encountered, resulting in a decrease in the efficiency of remote control operation can be solved. Thereby, when performing remote control operation, the other machine link diagnosis of FEP will not be encountered, thereby improving the efficiency of remote control operation.

[0035] In an exemplary embodiment, after the state of the front-end processor of the controlled network device is adjusted to the remote control ready state in step S204, the following operations may be performed:

[0036] 1) Adjusting the sending delay of the target master station in the front-end machine to the shortest remote control delay, wherein the target master station is a master station connected to the controlled network device; upon receiving a control instruction sent by the remote control device, controlling the target master station to send the control instruction to the controlled network device according to the shortest remote control delay.

[0037] In actual use, it takes a certain amount of time from the control command sent by the remote control device to the control command sent by the remote control device. The shorter the remote control delay, the faster the response speed to the control command. In order to reduce the delay of the controlled network device receiving the control command and improve the response speed of the control command, it is necessary to adjust the sending delay to the shortest remote control delay.

[0038] Furthermore, when the remote control delay is adjusted to the shortest remote control delay, upon receiving a control instruction sent by the remote control device, the target master station can be controlled to send a control instruction to the controlled network device according to the shortest remote control delay.

[0039] For example, the current remote control delay is the default remote control delay: 300ms. After the state of the front-end processor of the controlled network device is adjusted to the remote control ready state, it is determined that the remote control device is about to perform a remote control operation. At this time, the default remote control delay of 300ms can be adjusted to the shortest remote control delay of 120ms (300ms and 120ms are only examples, and the default remote control delay and the shortest remote control delay can be adjusted according to the specific situation).

[0040] 2) When the remote control device executes a second operation, receiving a cancel command sent by the remote control device, wherein the second operation includes at least one of the following: the remote control device does not display the program control interface for a period greater than or equal to a second preset period, and the remote control device completes the remote control operation; in response to the cancel command, determining that the remote control device has completed the remote control operation, and controlling the state of the front-end processor to be adjusted to a remote control cancel state, wherein when the state of the front-end processor is in the remote control cancel state, the front-end processor is allowed to perform another machine link diagnosis.

[0041] Among them, after controlling the state of the front-end processor to be adjusted to the remote control cancellation state, the method also includes: adjusting the sending delay of the target master station in the front-end processor to a default delay, wherein the target master station is a master station connected to the controlled network device; when performing link diagnosis of another machine, controlling the target master station to send a link diagnosis request to the controlled network device according to the default delay.

[0042] Through the above technical solution, it can be known that when the remote control device does not display the program control interface for a time period greater than or equal to the second preset time period, or the remote control device has completed the remote control operation, the remote control device can send a cancel command to the front-end machine of the controlled network device.

[0043] Furthermore, the front-end processor of the controlled network device responds to the cancel command and determines that the remote control device is not performing a remote control operation at the current time, and then the controlled network device can adjust the state of the front-end processor to the remote control cancel state, that is, allowing the front-end processor to perform another machine link diagnosis.

[0044] For example, assuming that the second preset time is 5 seconds, when the remote control device does not display the program control interface within 5 seconds, the state of the front-end processor can be adjusted to the remote control cancellation state, thereby allowing the execution of the link diagnosis of the other machine.

[0045] Furthermore, after the state of the front-end processor is adjusted to the remote control cancel state, the sending delay of the target master station can be adjusted to the default delay. That is, when the state of the front-end processor is adjusted from the remote control ready state to the remote control cancel state, when the state of the front-end processor is in the remote control ready state, the sending delay of the target master station is the shortest remote control delay, and when the state of the front-end processor is changed to the remote control cancel state, the sending delay of the target master station can be adjusted from the shortest remote control delay to the default delay.

[0046] It is understandable that the shortest remote control delay usually requires greater energy consumption to achieve fast data transmission, while the default delay can reduce energy consumption to a certain extent. Therefore, in order to reduce energy consumption and improve system stability, the shortest remote control delay can be adjusted to the default delay when the shortest remote control delay is not required.

[0047] 3) Start the timer and determine whether the control instruction sent by the remote control device is received before the timer times out; if it is determined that the control instruction sent by the remote control device is received before the timer times out, send the control instruction to the controlled network device to adjust the parameter information of the controlled network device according to the control instruction; if it is determined that the control instruction sent by the remote control device is not received before the timer times out, adjust the state of the front-end to the remote control cancellation state.

[0048] It can be seen from the above technical solution that after the state of the front-end is adjusted to the remote control ready state, a timer can be started to determine whether a control instruction sent by the remote control device is received before the timer times out. If a control instruction sent by the remote control device is received before the timer times out, the parameter information of the controlled network device can be adjusted according to the control instruction; if a control instruction from the remote control device is not received before the timer times out, the state of the front-end can be adjusted to the remote control cancel state.

[0049] For example: assuming that the timer timing is set to 2s, then after the state of the front-end is adjusted to the remote control ready state, the timer is started. If no control command from the remote control device is received within 2s, the state of the front-end can be adjusted to the remote control cancel state; if a control command sent by the remote control device is received within 2s, the parameter information of the controlled network device can be adjusted according to the control command.

[0050] 4) upon receiving the control instruction sent by the remote control device, determining whether the link diagnosis of the other machine is being executed; upon determining that the link diagnosis of the other machine is being executed, determining whether complete response information sent by the diagnosed device is received, wherein, in the process of executing the link diagnosis of the other machine, the front-end processor sends a diagnostic link request to each diagnosed device respectively, so as to determine the link information between the front-end processor and each diagnosed device respectively according to the complete response information sent by each diagnosed device; upon determining that the complete response information sent by the diagnosed device is received, suspending the execution of the link diagnosis of the other machine and sending the control instruction to the controlled network device.

[0051] It is understandable that, when a control instruction sent by the remote control device is received, it is necessary to confirm whether another machine link diagnosis is being executed at the current moment.

[0052] Assuming that the front-end processor is currently executing link diagnosis of another machine, it is necessary to determine the subsequent operations based on the execution status of the link diagnosis of the other machine. Specifically: when receiving the complete response information sent by the diagnosed device, the link information between the front-end processor and the diagnosed device can be determined, and after receiving the complete response information, the execution of the link diagnosis of the other machine is suspended so that the controlled network device executes the control instructions sent by the remote control device.

[0053] Wherein, after sending the control instruction to the controlled network device, the method further includes: determining whether the local remote control queue of the front-end is an empty queue, wherein the local remote control queue is used to carry the control instructions sent by the remote control device; when the local remote control queue of the front-end is an empty queue, continuing to execute the link diagnosis of the other machine to send link diagnosis requests to other diagnosed devices; when the local remote control queue of the front-end is a non-empty queue, continuing to suspend the execution of the link diagnosis of the other machine.

[0054] After sending a control instruction to the controlled network device, the local remote control queue can be obtained. If the local remote control queue is empty, it means that the control instruction sent by the remote control device has been executed. At this time, the link diagnosis of the other machine can be continued to continue the suspended link diagnosis of the other machine.

[0055] The above embodiment describes a technical solution for controlling the front-end processor of the controlled device to prohibit the execution of the other-machine link diagnosis when it is determined that the remote control device is to execute the remote control operation, thereby realizing that the other-machine link diagnosis of the FEP will not be encountered when the remote control operation is executed. The above technical solution realizes that the other-machine link diagnosis of the FEP will not be encountered when the remote control operation is executed, thereby improving the efficiency of the remote control operation.

[0056] Obviously, the above-described embodiments are only a part of the embodiments of the present application, not all of the embodiments. In order to better understand the above-mentioned link diagnosis control method, the above-mentioned process is described below in conjunction with the embodiments, but it is not intended to limit the technical solutions of the embodiments of the present application, specifically:

[0057] In an optional embodiment, a redundant master station remote control method and apparatus in a serial bus link conflict mode are proposed to coordinate the remote control of the HMI and the link diagnosis of the FEP. Figure 3 FIG. 1 is a schematic diagram of data flow in a remote control process of a redundant master station according to an optional embodiment of the present application. Figure 3 As shown, Figure 3 Including: RTDB is the real-time database, Dev represents the device, FEP-A is the actual main front-end processor, FEP-B is the actual backup front-end processor, among which, based on Figure 3 The data flow transmission process of the remote control process of the redundant master station is as follows:

[0058] Step S1, when the time for the user (i.e., the target object of the present application) to enter the program control interface of the HMI reaches a predetermined time (the predetermined time is the first preset duration of the present application), or when a valid check item of any program control card in the program control interface is selected (i.e., the target operation of receiving the target object of the present application selects the program control card information of the controlled network device in the program control interface), a remote control pre-activation command (i.e., adjusting parameter PreRC=1, which is also the activation command of the present application) can be issued to the FEP (i.e., the front-end processor of the controlled network device of the present application).

[0059] The program control card may be composed of a two-dimensional table, a link, and device information. The predetermined time may be configured by itself. For example, in an optional embodiment of the present application, the predetermined time is configured to be 3s.

[0060] Step S2, start the timeout timer (i.e., the timer of the present application), and set the timeout period of the timer to 120s (the timer timeout period can be configured by itself, for example, in an optional embodiment of the present application, the timeout period of the timer is configured to 120s).

[0061] Step S3, when the FEP receives the pre-activation command, it can set all related drivers (the related drivers are the master stations in the front-end processor of this application, and there may be multiple master stations) to the remote control pre-ready state (i.e. the remote control ready state of this application). During the remote control pre-ready state, all related drivers of the FEP need to suspend the link diagnosis of other machines, and at the same time, the sending delay of all related drivers needs to be dynamically adjusted to the shortest remote control delay.

[0062] For example: assuming that the conventional transmission delay is 200ms, and based on the shortest delay time of the master station request or command that can be tolerated by the device in the optional embodiment of the present application, the shortest remote control delay is set to 20ms.

[0063] In this case, after it is determined that the pre-activation instruction has been received and all related drivers are set to the remote control ready state, the 200ms sending delay is adjusted to the shortest remote control delay of 20ms, so as to reduce the time delay from the remote control device sending the pre-activation instruction to the receiving of the pre-activation instruction sent by the remote control device, and improve the response speed of the remote control operation.

[0064] Step S4, assuming that the time when the user switches out of the HMI program control interface reaches the second predetermined time (the second predetermined time is the second preset duration of the present application, and the second predetermined time can be specifically configured according to the specific embodiment, and can be consistent with the predetermined time, or can be inconsistent with the predetermined time. For example, in the optional embodiment of the present application, the second predetermined time is set to 3s consistent with the predetermined time), or the HMI program control is completed. In the above two cases, the timer can be turned off, and at the same time, a remote control preparation cancellation instruction (i.e., the cancellation command of the present application) is issued to the FEP. When the FEP receives the remote control preparation cancellation instruction, the remote control ready state of all related drives (i.e., the remote control cancellation state of the present application) is canceled, and all related drives enter the normal data acquisition mode. That is, when the FEP receives the remote control preparation cancellation instruction, the FEP enters the remote control cancellation state, and the FEP's other machine link diagnosis can be executed at this time.

[0065] Through the above technical solution, on the one hand, before the host sends a remote control, it first determines whether another machine link diagnosis is currently being performed. Assuming that another machine link diagnosis is being performed, the remote control is temporarily not sent, waiting for the next opportunity for the master station to send a request. The next opportunity for the master station to send a request may be the moment when an execution cycle of the other machine link diagnosis is completed.

[0066] On the other hand, the situations in which the execution of this round of other-machine link diagnosis is suspended are: 1) Before the host sends the other-machine link diagnosis, the local remote control queue can be checked first. When it is determined that the local remote control queue is empty, the other-machine link diagnosis can be performed; when it is determined that the local remote control queue is not empty, the execution of this round of other-machine link diagnosis is suspended; 2) After the host receives a complete response from the device (the host receives a complete response from the device, which means that the diagnostic process for diagnosing a device in the device's other-machine link diagnosis has ended), before preparing to send the next request for other-machine link diagnosis, the host also needs to check the local remote control queue first. If the local remote control queue is not empty, that is, there are unfinished remote control operations, the current round of other-machine link diagnosis is suspended.

[0067] After pausing the current round of link diagnosis of another machine, you need to wait until the remote control queue is empty before you can continue to execute the suspended link diagnosis.

[0068] It should be noted that after the host receives the device response to the previous another machine link diagnostic request and processes the device response to the previous another machine link diagnostic request, and / or before sending the next another machine link diagnostic request, it is necessary to use the shortest remote control delay as the sending delay between the two requests to maintain the fastest data acquisition frequency of the relevant equipment during programming.

[0069] Through an optional embodiment of the present application, when it is determined that the remote control device is to perform a remote control operation, the front-end processor of the controlled device is prohibited from performing another machine link diagnosis, thereby achieving that when performing the remote control operation, the FEP's another machine link diagnosis will not be encountered.
