Industrial control system manufacturers produce industrial control systems with different functional emphasis in order to meet different industrial manufacturing requirements. The different specifications in the embodiments of the present specification may be various situations such as different manufacturers, different functional emphasis points, different core components, and the like of the industrial control systems, so that the industrial control systems of different specifications may present different operating states when operating the same production equipment group to complete the same production task. The industrial control system is generally composed of core components such as a Programmable Logic Controller (PLC), a Distributed Control System (DCS), a data acquisition and monitoring System (SCADA), a Remote Terminal Unit (RTU), a human-computer interaction interface device (HMI) and the like, and is connected to the production equipment group to control the action of each production equipment in the production equipment group. Common production facilities are for example: mixers, industrial robots, conveyor belts, dehumidifiers, heating devices, etc. In the embodiments of the present specification, the production equipment group used may be the production equipment itself, which is a production equipment model group obtained by scaling down (or reducing) the production equipment in equal proportion.
The connection cabinet, also called a terminal box, is an accessory product for realizing electrical connection, and the industrial control system needs to acquire operation data of the production equipment from the production equipment group through an input/output (IO) port, send a corresponding control instruction according to the acquired operation data, and send the control instruction to the production equipment group through the IO port. In an industrial process, an industrial control system generally controls one or more sets of production equipment, each set of production equipment includes at least one production equipment, and each production equipment is provided with a plurality of IO ports that need to communicate with the industrial control system, so that the number of IO ports connected to the production equipment sets by the industrial control system increases. In order to reduce the number of IO ports of the industrial control system connected to the production equipment group, the industrial control system is connected to the wiring cabinet, and the ports in the wiring cabinet are connected in series and in parallel, so that the number of the IO ports connected to the production equipment group is reduced. When the production equipment group is connected with a plurality of wiring cabinets, IO ports output by different wiring cabinets are connected in parallel to the IO ports of the production equipment group.
When the industrial control system is tested, the method mainly comprises the following two test scenes:
the method comprises the following steps of firstly, testing the running state of the industrial control system under a normal condition; and a second scenario is that the operation state of the industrial control system under the attacked condition is tested.
Aiming at the second scene, the running states and running environments of the network architecture, the system equipment and the service process in the real network space can be simulated and reproduced through the network target range, and the network target range is applied to network simulation attack on the industrial control system, so that the real running states of the industrial control systems with different specifications are tested when the industrial control systems suffer network attack. (when performing a cyber attack simulation test, in one possible embodiment, to prevent damage to the production equipment, the test is performed using a production equipment model set).
The following is a detailed description of examples of the present specification.
The embodiment of the specification provides a test method of industrial control systems with different specifications, which is applied to a test system, wherein the test system comprises a test work propulsion module and a power supply control module, and the power supply control module is used for controlling power switches of a plurality of wiring cabinets; the wiring cabinets are connected to the same production equipment group and are connected with a plurality of industrial control systems of different specifications one by one; when the power supply of any wiring cabinet is turned on, the industrial control system connected with the wiring cabinet is connected and communicated with the production equipment group. Fig. 1 is a flowchart illustrating a testing method of an industrial control system with different specifications according to an embodiment of the present disclosure, where the method includes the following steps:
Specifically, in the embodiment of the present specification, each connection cabinet is provided with a power switch, the power switch is controlled by the power control module, and when a power switch start signal is received from the power control module, the power switch of the connection cabinet is turned on; and when receiving a power switch closing signal, closing the power switch of the wiring cabinet.
When the industrial control system connected with the wiring cabinet is connected and communicated with the production equipment group, the industrial control system sends a control instruction to the production equipment group to control the action of each production equipment in the production equipment group, and further the industrial production task is completed.
In the embodiment of the specification, the currently unique target industrial control system to be tested is determined from a plurality of industrial control systems through the test work propulsion module, so that the target industrial control system is determined to be the currently unique industrial control system which is connected and conducted with the production equipment group. The method for determining the target industrial control system by the test work propulsion module is arbitrary, for example, an intelligent determination model is arranged in the test work propulsion module, and different test schemes are arranged for each industrial control system according to the performance of each industrial control system, so that the current target industrial control system is determined according to the test schemes. And after the test work propulsion module determines the target industrial control system, sending a test work propulsion instruction for designating the target industrial control system to the power supply control module, so that the power supply control module determines the target industrial control system which is allowed to be connected and conducted with the production equipment group at present according to the test work propulsion instruction.
And 102, responding to the test work propulsion instruction by the power supply control module, and determining a target wiring cabinet connected to the target industrial control system.
Specifically, after the test work propulsion instruction is sent to the power control module through step 101, the power control module receives the test work propulsion instruction and acts in response to the test work propulsion instruction. The power control module stores the connection relation between each industrial control system and the wiring cabinet, and after the target industrial control system is determined according to the test work propulsion instruction, the target wiring cabinet connected with the target industrial control system can be uniquely determined according to the connection relation.
103, the power control module controls the power of the target connection cabinet to be turned on the premise of determining that the power of all other connection cabinets except the target connection cabinet is turned off, so that the target industrial control system can control the production equipment group in a testing manner.
Specifically, after the power control module determines the target connection cabinet according to step 102, the connection cabinets other than the target connection cabinet in the connection cabinets connected to the power control module are determined as other connection cabinets.
In the embodiment of the specification, a plurality of industrial control systems with different specifications are connected to the same production equipment group, and if each industrial control system is connected and conducted with the production equipment group, each industrial control system sends a control instruction to the production equipment group, so that the control instructions received by the production equipment group are mixed together, and further, the control instructions conflict to cause the problems of production equipment group faults and the like. Therefore, in the process of connecting a plurality of industrial control systems with the same production equipment group, only one industrial control system can be connected and conducted with the production equipment group at the same time. Therefore, before the target wiring cabinet is opened, whether the power supply of each other wiring cabinet is closed or not needs to be determined, when the power supplies of the other wiring cabinets are all closed, it is ensured that the opening of the target wiring cabinet does not cause a plurality of industrial control systems to simultaneously send control instructions to the production equipment group, and further the production equipment group is out of control due to control instruction conflict.
Meanwhile, determining that the power supplies of all other wiring cabinets are turned off may be performed for each target wiring cabinet, verifying whether the power supply of each wiring cabinet is turned off before controlling the power supply of the target wiring cabinet to be turned on each time, and turning off the other wiring cabinets with the power supplies turned on if the wiring cabinet with the power supplies turned on exists in the other wiring cabinets.
In order to solve the problem of how to measure the operating states of industrial control systems with different specifications when controlling production equipment sets with the same specification, in the prior art, a set of production equipment set is usually configured for each industrial control system, so as to operate each industrial control system and each set of production equipment set connected to the industrial control system at the same time. Compared with the prior art, the embodiment of the specification effectively reduces the number of the production equipment groups on the basis of ensuring that the industrial control systems with different specifications can control the production equipment groups with the same specification by providing the scheme of connecting the industrial control systems with different specifications to the same set of production equipment group.
Furthermore, in the embodiment of the present specification, a wiring cabinet is provided for each industrial control system, the industrial control system is connected to the wiring cabinet, then the wiring cabinet is connected to the production equipment group, and the number of IO interfaces, which are connected to the production equipment group, of each industrial control system is effectively reduced through series-parallel connection of ports in the wiring cabinet.
Furthermore, when a plurality of industrial control systems are all connected to a set of production equipment group, if the plurality of industrial control systems are operated simultaneously and connected and conducted with the same production equipment group according to the thought of the prior art, a problem that control instructions sent by the plurality of industrial control systems to the same production equipment group conflict with each other can be caused.
In one possible embodiment, the test system further comprises a remote control module; before the test work advancement module determines a target industrial control system currently to be tested among the plurality of industrial control systems, the method further comprises the steps of:
104, the remote control module sends a mode switching instruction to the test work propulsion module so that the test work propulsion module responds to the mode switching instruction to switch the operation mode of the test work propulsion module, and determines a current target industrial control system to be tested in the plurality of industrial control systems based on the operation mode; the mode switching instruction comprises: and setting the operation mode to be a manual mode and setting the operation mode to be an automatic mode, wherein when the mode switching instruction specifies that the operation mode of the test work propulsion module is set to be manual operation, the mode switching instruction further comprises a manual test instruction updated by a user.
Specifically, the test work propulsion module has two modes of operation during operation, namely automatic operation and manual operation. The remote control module is used for controlling the operation mode of the test work propulsion module and sending a mode switching instruction to the test work propulsion module, so that the test work propulsion module responds to the mode switching instruction and switches the operation mode of the test work propulsion module, and the method comprises the following steps: the automatic operation is switched to manual operation, and the manual operation is switched to automatic operation (if the test work propulsion module originally operates automatically, the specified operation mode in the mode switching instruction is set to be automatic operation, the switching is not performed, and similarly, if the test work propulsion module originally switches manually, the specified operation mode in the mode switching instruction is set to be manual switching, the switching is not performed). Therefore, when a user wants to test a specified industrial control system, a mode switching instruction of 'setting the operation mode to be manual operation' is sent to the test work propulsion module through the remote control module, and an updated manual test instruction set by the user is carried in the mode switching instruction and sent to the test work propulsion module. Similarly, the operational mode of the test work propulsion module may be set to run automatically when a user wants to automatically test at least one of the plurality of industrial control systems according to a pre-stored automatic test program without human intervention.
For different operation modes, it may be determined whether the current operation is manual or automatic by setting an operation mode flag in the test work propulsion module, e.g. setting the operation mode flag to M, initializing M each time the test work propulsion module is turned on. After the test work propulsion module sets the operation mode flag M to automatic operation (or manual operation) in response to the mode switching instruction, a setting completion instruction is fed back to the remote control module.
By the method, the mode switching of the test work propulsion module can be realized, and when a user wants to participate in the process of determining the target industrial control system, the mode switching can be switched to manual operation; when the user does not want to participate in the process of determining the target industrial control system, the automatic operation can be switched to the automatic operation, and the user participation degree is improved.
Meanwhile, the test work propulsion module does not execute a manual test instruction when automatically operating. When the mode switching instruction designates that the operation mode of the test work propulsion module is set to be the manual operation mode, the manual test instruction is carried in the mode switching instruction, and when the test work propulsion module receives the mode switching instruction, the operation mode is switched to be the manual operation according to the mode switching instruction, so that the manual test instruction can be directly executed, whether the current operation mode is the manual operation mode or not does not need to be verified, the verification time is shortened, and the data processing speed is improved.
Fig. 2 is an overall flowchart of a method for controlling connection and conduction between a target industrial control system and a production equipment group, provided by an embodiment of the present specification, and as shown in fig. 2, the method includes the following steps:
s201, the remote control module sends a mode switching instruction to the test work propulsion module.
S202, the test work propulsion module responds to the mode switching instruction and switches the operation mode.
And S203, determining a target industrial control system by the test work propulsion module after the operation mode is switched according to the S202.
And S204, after determining the target industrial control system according to the S203, the test work propulsion module sends a test work propulsion instruction appointed with the target industrial control system to the power supply control module.
And S205, the power supply control module responds to the test work propulsion instruction and determines a target wiring cabinet connected to the target industrial control system.
S206, the power control module judges whether the power of other wiring cabinets is completely closed, and if so, the step S207 is executed. (it should be noted that when it is determined that the power supplies of the other junction boxes are not turned off, the process may proceed to step S207 after turning off the power supply of each of the other junction boxes).
And S207, the power control module turns on the power supply of the target wiring cabinet, so that the target industrial control system connected with the target wiring cabinet is connected and conducted with the production equipment set.
For a detailed description of the contents related to steps S201 to S207, refer to step 101 to step 104, which are not described herein again.
It should be noted that the test work propulsion module and the power control module may be disposed in the same device, or may be disposed in different devices; when the test work propulsion module and the power supply control module are deployed in the same device, the device and the device where the remote control module is located are different devices; for example, the test work propulsion module and the power supply control module are deployed in a PLC, and the remote control module is deployed in a device capable of sending a mode switching instruction to the PLC (for example, in a terminal such as a computer or a tablet, programming software for generating a mode switching instruction recognizable by the PLC is installed in the terminal). When the test work propulsion module and the power control module are deployed in different devices, the test work propulsion module and the remote control module are deployed in the same device (for example, a terminal such as a computer or a tablet), and the power control module is deployed in other devices (for example, a PLC). When a graphical user interface is present on the device deployed by the remote control module, or the remote control module is in communication with the graphical user interface, the current status of the test job propulsion module (e.g., the current operating mode, the target industrial control system currently being tested) may be sent to the graphical user interface for display.
When the mode switching instruction is generated every time, the remote control module sends a power supply closing instruction for closing each wiring cabinet to the test work propulsion module so as to ensure that the power supplies of all the wiring cabinets are closed when the test work propulsion module switches the operation mode, all the industrial control systems cannot be connected and conducted with the production equipment group, and the situation that the industrial control systems in a new operation mode and the industrial control systems in an old operation mode are connected and conducted with the production equipment group at the same time due to mode switching is prevented. Similarly, when the test work propulsion module is closed, a power supply closing instruction is also generated, so that the phenomenon that the industrial control system is connected and conducted with the production equipment set when the test work propulsion module is closed is prevented.
The manual test command and the mode switching command can be sent together or separately, and the manual test command can be sent independently when the mode switching command does not exist. For example, after a mode switching instruction "switch the operation mode from automatic operation to manual operation" is sent to the test work propulsion module, a manual test instruction is sent to the test work propulsion module alone. By means of the mode that the manual test instruction and the mode switching instruction are sent separately, when the running mode of the test work propulsion module is not set, the manual test instruction can be sent to the test work propulsion module through the remote control module.
In a possible embodiment, the test work advancing module includes a preset test plan, the test plan is provided with a predicted test duration and a test sequence of each industrial control system, and if the current operation mode of the test work advancing module is automatic operation, the test work advancing module determines a target industrial control system to be currently tested in the plurality of industrial control systems, which includes the following two cases:
in case one, when the test plan is initially executed, the test work propulsion module determines the industrial control system with the first test sequence as the target industrial control system to be tested.
Specifically, the test plan may be preset in the test work propulsion module, or may be obtained from the remote control module; when the test plan needs to be adjusted, the adjusted new test plan can be sent to the test work propulsion module through the remote control module, or the new test plan can be carried in a mode switching instruction for setting the running mode of the specified test work module to be automatic running. The test plan may include each of the industrial control systems connected to the wiring cabinets, or may include some of the industrial control systems determined from a plurality of industrial control systems.
In this embodiment, the test plan may further include a different test program assigned to each industrial control system, or assign the same test program to each industrial control system, or when multiple rounds of tests are performed on each industrial control system in the test plan, a different test program may be set for each round of tests, but the same test program is run during each industrial control system in the same round of execution. (for example, in a first round, each industrial control system executes a first test program, the predicted test time length of each industrial control system is a first time length; in a second round, each industrial control system executes a second test program, the predicted test time length of each industrial control system is a second time length, and the like). Each industrial control system in the test plan is sequentially used as a target industrial control system according to the test sequence, and when the target industrial control system starts a testability control production equipment group, only the predicted test time length of the target industrial control system is operated.
The initial execution refers to the target industrial control system determined when the test work propulsion module executes the test plan for the first time in a certain operation mode. When the test plan is initialized and executed, according to the test sequence in the test plan, the industrial control system with the first test sequence is directly determined as the target industrial control system to be tested.
Example 1, when the test plan is to test the first industrial control system, the second industrial control system, and the third industrial control system:
when only one round of testing is performed, the test sequence is: 1. the industrial control system is unified; 2. a second industrial control system; 3. and a third industrial control system. The predicted test duration is in turn: 1h;2h; and (5) h.
The industrial control system is determined to be the target industrial control system when the test plan is initially executed. Meanwhile, the serial number of the target industrial control system to be tested currently can be referred to by the setting flag S, for example, when S is 1, the industrial control system is the target industrial control system to be tested previously.
Example 2, based on the case in example 1, when a plurality of rounds of tests (for example, 2 rounds) are performed, the test sequence is: 1. the industrial control system is uniform; 2. a second industrial control system; 3. a third industrial control system; 4. the industrial control system is uniform; 5. a second industrial control system; 6. and a third industrial control system. (i.e., sequentially performed in the order of S =1, S =2, S =3, S =4, S =5, S = 6).
The industrial control system is determined as the target industrial control system (S = 1) when the test plan is initially executed. It is also noted that in the second run, the industrial control system is the fourth industrial control system to be tested in the test sequence (S = 4).
And secondly, when the test work propulsion module tests any industrial control system in the test plan process, when the countdown of the expected test duration of the industrial control system is finished, determining the industrial control system positioned at the rear position of the industrial control system in the test sequence as the target industrial control system to be tested.
Specifically, if the current test work progress module is not initially executed (i.e., is executing the test plan) in the specific operation mode, the industrial control systems that are running and testing must exist, because each industrial control system is provided with the expected test duration, when the countdown of the expected test duration of the industrial control system is finished, the industrial control system finishes the execution of the test task, and the industrial control system that is located one after the industrial control system in the test sequence is determined as the target industrial control system to be tested.
Example 3, introduced according to the example in example 1, when only one round of testing is performed, the test sequence is: 1. the industrial control system is unified; 2. a second industrial control system; 3. and a third industrial control system. The predicted test duration is in turn: 1h;2h; and (5) h.
Since the test plan is not initially running, i.e. any of the industrial control systems is currently being tested (assuming industrial control system unity, i.e. S = 1).
Then, since the expected test duration of the industrial control system is 1h, when the 1h countdown is finished from the beginning of the test of the industrial control system, the industrial control system two is determined as the target industrial control system (i.e., after the start of the test of the industrial control system for 1h, S = 2).
By the method, when the test work propulsion module is in the automatic operation mode, the only target industrial control system can be automatically determined from the plurality of industrial control systems. By setting the operation mode of automatic operation, when each industrial control system (a plurality of industrial control systems) needs to be tested in sequence according to the test sequence, the industrial control systems can be tested automatically, and the manual workload is reduced.
It should be noted that the expected test duration and test sequence of each industrial control system set in the test plan may be fixed quantities or variable quantities that can be intelligently adjusted. For example, the accumulated test duration of each industrial control system in both the manual operation mode and the automatic operation mode in each period may be recorded, and the expected test duration in the test plan may be adjusted according to the accumulated test duration, so that the total test duration of each industrial control system in each period is approximately the same.
Or, the test duration of each industrial control system is adjusted according to the performance of each industrial control system disclosed in the disclosure, for example, the test duration of the industrial control system with better performance is reduced, and the test duration of the industrial control system with poorer performance is increased. For another example, when some functional defects exist in an industrial control system of a certain specification, an operating program for the function may be set in the test plan, and the functional defects may be tested, and the test time for the function may be increased appropriately.
The test plan may also be made for only one industrial control system. For example, different test programs are set up for the industrial control system, each test program being executed for a certain test duration.
In one possible embodiment, if the current operation mode of the test work propulsion module is manual operation, the test work propulsion module determines a target industrial control system to be currently tested among the plurality of industrial control systems, including the steps of:
and the test work advancing module responds to the manual test instruction and determines the industrial control system specified in the manual test instruction as the target industrial control system to be tested currently.
Specifically, the industrial control system specified in the manual test command is input by the user through the device in which the remote control module is located, for example, when the device in which the remote control module is located is a computer terminal, through one or more input devices (a mouse, a keyboard, and a graphical user interface) of the computer terminal. The remote control module generates manual test instructions containing the user-specified industrial control system in response to information input by the user via the input device.
After the test work propulsion module receives the manual test instruction, whether the current operation mode is the manual operation mode needs to be verified, and if the current operation mode is the manual operation mode, the industrial control system specified in the manual test instruction is determined to be the target industrial control system to be tested currently. If the operation mode of automatic operation is adopted, the manual test instruction is not executed and is discarded.
By setting the running mode of manual running, the participation of the user is improved, and by verifying whether the running mode is the running mode of manual running indeed, the testing authority of the user is expanded on the basis of ensuring that the testing work propulsion module is not interfered by a manual testing instruction during automatic running.
In one possible embodiment, determining that the power of all other junction boxes except the target junction box is turned off includes the following two cases:
in the first case, if the test work propulsion module is initially operated in any operation mode, determining that the power supplies of all other wiring cabinets except the target wiring cabinet are turned off; the operation modes comprise automatic operation and manual operation.
Specifically, when the test work propulsion module enters any one operation mode and is initially operated (operated for the first time), the power supply of each wiring cabinet is turned off, so that the power switch condition of each wiring cabinet does not need to be inquired at the moment, and the power supply of all other wiring cabinets except the target wiring cabinet is automatically determined to be turned off. The initialization operation in any operation mode comprises the following steps: after manual operation is carried out, a target industrial control system is determined for the first time; after the automatic operation is carried out, the target industrial control system is determined for the first time.
Or in a second case, if the test work propulsion module operates in any one of the operation modes in a non-initialization manner, after determining a target wiring cabinet connected to the target industrial control system, the power control module closes the wiring cabinet connected to the currently operating industrial control system, and determines that the power of all other wiring cabinets except the target wiring cabinet is closed.
Specifically, non-initialized operation refers to that at least one other target industrial control system has been determined and has been in operation for a period of time in the current operating mode. Then, since at least one other industrial control system has been determined before, it is necessary to operate the industrial control system before the new target connection cabinet is opened, and since it is checked whether the other connection cabinet is closed before the new industrial control system is operated each time, it is ensured that only the unique industrial control system is operated at this time, it is possible to determine that the power supplies of all the other connection cabinets except the target connection cabinet are turned off after the connection cabinet connected to the currently-operating industrial control system is turned off.
By the method, when the target wiring cabinet is opened every time, whether the power supply of each other wiring cabinet is turned off or not does not need to be checked in sequence, and the data calculation amount can be reduced.
