[0028] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme 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 a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0029] In the actual production scenarios of different industrial sectors, one industrial scenario will actually be controlled by control systems of multiple brands and models. In the same industry, different companies can select control systems of different brands for production control. Different factories of the same company can also choose control systems of different brands and models or different models of the same brand to control the same production link. The research core of the industrial control range is mainly on the control system. Due to the limitations of the site, funds and other aspects of the range construction, usually in an industrial simulation scenario, only one brand and one model of industrial control system can be used for simulation control. The existing switching devices mostly use direct Plug-in terminal blocks or universal switch switching devices, but the main defects of the existing single-business scenario industrial control system switching solutions are: (1) Plug-in wiring cabinet solution: The main problem is that the plug-in wiring cabinet solution is very cumbersome. If the production device has 100 IO points and there are 2 different industrial control systems to control the production device, the wiring cabinet must have at least 300 wiring points reserved, and the wiring of the 100 IO points must be manually plugged in and replaced during switching; (2) Universal switch solution: The main disadvantages of this solution are that it supports few points and high cost, and the universal switch usually supports the switching of two control systems at most. When the number of control systems is greater than three, this solution will not be supported.

[0030] Therefore, the existing technology only allows two systems to control one set of industrial simulation equipment at the same time. When it is necessary to use a set of industrial industry simulation models to simulate industrial systems in different regions and countries, the existing technology has very great limitations.

[0031] Based on this, an embodiment of the present application provides a switching device and method for multiple control systems, which can realize a technical solution of controlling a set of production equipment through multiple control systems, and can realize dynamic switching of multiple control systems, thereby solving the limitations of existing control system switching.

[0032] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a switching device for multiple control systems provided in an embodiment of the present application. Figure 1 As shown in, the switching device 100 provided in the embodiment of the present application includes: at least one active control wiring cabinet 110, at least one control system 120, a production device 130, a switching controller 140 and a switching control monitoring device 150: each active control wiring cabinet 110 is connected to at least one control system 120; all active control wiring cabinets 110 are connected to the production device 130; the switching controller 140 is connected to the switching control monitoring device 150; the switching controller 140 is connected to all active control wiring cabinets 110.

[0033] In an implementation manner provided in the present application, all active control wiring cabinets 110 are connected in parallel to the production device 130 via production control IO lines.

[0034] In another embodiment provided in the present application, each active control wiring cabinet 110 includes at least one relay, and each relay is connected to a control system 120 .

[0035] In this way, the corresponding relay can be activated to control the connected control system 120 to start, so that the production device 130 (or simulation device) can be controlled by the activated control system 120.

[0036] Here, each independent control system 120 connects the IO lines to the corresponding active control wiring cabinet 110 .

[0037] Therefore, the active control wiring cabinet 110 is used to connect the control system 120 and the production device 130 through the IO line. Among them, the active wiring cabinet 110 needs to be powered on. When the power of the active wiring cabinet 110 is turned on or the relay is started, the control system 120 and the production device 130 are connected and the production device 130 can be controlled by the control system 120 connected to the active wiring cabinet 110.

[0038] It should also be noted that the active wiring cabinet 110 has a power supply. All relays in each active cabinet are concentrated together in a group of lines. The activation of the relays is controlled by the power supply. When the corresponding relay cabinet of the group is the corresponding scene, the relay cabinet of the group is activated, and the others are not activated. The power supply of the active cabinet controls the switching scheme through remote IO, which is limited by the size of the site but not by the scale of the scene. The relay protection device can quickly and accurately respond to various faults or abnormal operating conditions of the relay, and act within the specified time limit to trip the circuit breaker, and can promptly determine the cause and location of the damage, and quickly respond to the fault, thereby protecting the safety of the entire system. At the same time, the active control wiring cabinet device switching controller and switching control monitoring device can be programmed and expanded as needed, and can centrally manage and monitor the control system connected to the device. The system greatly increases the scalability, safety and convenience, realizes telemetry, remote control and remote signaling, and can be flexibly constructed, providing a solution for the study of multi-control system test scenarios, while reducing the complexity of the system and greatly reducing the cost of setting up the test environment.

[0039] In another implementation manner provided in the present application, the switching controller 140 is connected to the switching control monitoring device 150 via Ethernet, and the switching controller 140 and the switching control monitoring device 150 are set with the same IP address.

[0040] In this way, by connecting via an Ethernet cable and configuring the same network segment IP address, normal network communication can be ensured between the switching control monitoring device 150 and the switching controller 140.

[0041] In another embodiment provided in the present application, the switching controller 140 is connected to a power control point of each active control wiring cabinet 110 via a power control IO line.

[0042] In another implementation manner provided in the present application, the switching control monitoring device 150 is used to send a control system switching instruction to the switching controller 140 and determine a scene state.

[0043] In another embodiment provided in the present application, the switching control device 140 is used to receive a control system switching instruction, and start the target control system 120 according to the received control system switching instruction to control the production device 130.

[0044] Here, the control system switching instruction may include a switching type, a switching timing, a switching target, etc. The control system switching instruction may start / stop switching of one or more control systems 120 .

[0045] The switching type may include, for example: automatic switching mode, manual switching mode, and switching to the Nth control system, etc.

[0046] Here, the switching controller 140 is used to switch the control system 120 that currently controls the production device 130. A program can be written for the switching controller to realize automatic switching control of the control system 120, or a switching instruction can be manually sent to the switching controller 140 through the switching control monitoring device 150 to perform manual switching control of the control system 120.

[0047] Here, the switching control monitoring device 150 is used to write and send automatic control logic to the switching controller 140, and at the same time, it can remotely monitor the current scene status; and the switching control monitoring device 150 can be used to send instructions to the switching controller 140 to switch the control system 120.

[0048] The switching monitoring device 150 is used to send a control system switching instruction to the switching controller 140 to switch the control system 120 (target control system) that actually controls the production device.

[0049] In this way, the technical solution provided by this application can effectively solve the limitations existing in the current target range construction, and can realize the control of a set of industrial production (simulation) equipment through multiple sets of industrial control systems, and can realize the dynamic switching of the control system used by the production equipment, effectively expanding the industrial control systems of different regions and countries that can be simulated in the industrial control target range, greatly improving the simulation capability and simulation level of the industrial control target range.

[0050] For examples, see Figure 2 , Figure 2 This is a flow chart of a method for switching multiple control systems provided by an embodiment of the present application. Figure 2 As shown, the switching method is applied to the above-mentioned switching device, and the switching method includes:

[0051] S201: The switching control monitoring device sends a control system switching instruction to the switching controller.

[0052] S202: The switching controller controls the corresponding active control wiring cabinet to be powered on in response to the control system switching instruction to start the target control system, so that the target control system controls the production device.

[0053] With respect to step S201, the control system switching instruction includes information such as the switching type and the switching actuality.

[0054] With respect to step S202 , when the target control system is started according to the control system switching instruction, one or more target control systems may be started.

[0055] In this way, the switching control monitoring device monitors the status of each control system and performs switching operations when necessary to ensure production continuity and efficiency.

[0056] Here, the switching process of steps S201-S202 is illustrated by example: when the switching control monitoring device detects that the currently running main control system fails or requires maintenance, it sends a control system switching instruction to the switching controller. After receiving the switching instruction, the switching controller immediately responds and executes the following steps: Control switching to the backup control system: The switching controller sends the control system switching instruction to the corresponding active control wiring cabinet through its own logical judgment. After the active control wiring cabinet receives the instruction, it controls the power supply to be turned on and starts the backup control system. Start the target control system: After the backup control system detects that the power is turned on, it starts the self-check and initialization process. Control the production equipment: Once the backup control system starts normally, it will take over the control of the production equipment and ensure the continuous operation of the production process before the main control system is restored.

[0057] In this way, the switching control monitoring device works in conjunction with the switching controller to achieve rapid switching and production continuity when the main control system fails. This mechanism effectively improves the reliability and stability of the production line and ensures the achievement of production goals. "

[0058] For examples, see Figure 3 , Figure 3 A scene switching control flow chart provided in this application. Here, the scene switching is to control system switching, such as Figure 3 As shown, the switching control process includes the following steps:

[0059] S1. Start the switching controller.

[0060] S2. Initialize the switching controller (initialize the timer T, the control mode flag M, and the control state flag S).

[0061] S3. Enable receiving remote commands (the subsequent switching control state process and receiving remote command process are performed concurrently).

[0062] S4, receiving a remote command, and determining whether the command type is a switch to automatic mode command, a switch to manual mode command, or a switch to the Nth control system command.

[0063] S4.1. Upon receiving the instruction to switch to the automatic mode, the control mode flag M is set to automatic or the control mode flag M is kept in the automatic state, and the process S4 is re-entered.

[0064] S4.2. Upon receiving the instruction to switch to manual mode, the control mode flag M is set to manual or the control mode flag M is kept in manual state, and the process S4 is re-entered.

[0065] S4.3. Receive the instruction to switch to the Nth control system.

[0066] S4.3.1. The current mode is manual. Set the control status flag S to N and re-enter process S4.

[0067] S4.3.2. Currently in automatic mode, discard the received instructions, do not perform any actions, and re-enter process S4.

[0068] S5. Switch the control mode according to the command, i.e. the control state.

[0069] S5.1. Determine the state of the control mode flag M.

[0070] S5.1.1, M is automatic mode, determine whether the timer T%t is 0 (t is the period for setting automatic scene switching, and the value of t can be adjusted in the program according to actual conditions. The determination is to determine whether the timing time reaches an immediate period).

[0071] S5.1.1.1. T%t is not 0, re-enter process 5.1.

[0072] S5.1.1.2, T%t is 0, and it is determined that S>n (n is the number of control systems currently actually deployed).

[0073] S5.1.1.2.1, S>=n holds, let S=0, the switching controller enables the power supply of the active control wiring cabinet S through the power control IO line, and does not enable the power supply of the non-active control wiring cabinet S.

[0074] S5.1.1.2.2, S>=n does not hold, let S=S+1, the switching controller enables the power supply of the active control wiring cabinet S through the power control IO line, and does not enable the power supply of the non-active control wiring cabinet S.

[0075] S5.1.1.2.3. Re-enter process S5.1.

[0076] S5.1.2, M is the manual mode, the switching controller enables the power supply of the active control wiring cabinet S through the power control IO line, and does not enable the power supply of the non-active control wiring cabinet S, and re-enters the process S5.1.

[0077] In this way, this solution solves the problem of the need for diverse physical equipment and multiple production devices in the field of industrial control range construction. It realizes the method of controlling the same production device through multiple control systems to simulate the industrial production environment in different countries and regions of the same industry. It also effectively reduces the number of physical equipment required for production devices during the range construction process, while reducing the demand for site area, and solving the problem of the need to quickly switch range scenes in safety experiments.

[0078] By specifically connecting and combining the control system, active control junction cabinet, production equipment, switching controller, and switching control monitoring device, a design scheme is formed that can meet the needs of jointly controlling a set of production equipment through multiple different types of control systems.

[0079] By connecting the IO wiring from the active control wiring cabinet to the production device in parallel and using a switching controller to control the power supply of the active control wiring cabinet, it is achieved that when the switching controller enables the power supply of a certain active control wiring cabinet, the corresponding control system can control the production device, and other control systems cannot control the production device. Through this switching method, the number of control systems that a set of production equipment can support simultaneously is greatly expanded.

[0080] Through the switching process in this patent, it is possible to realize automatic switching of the control system used by the production equipment and manual switching by remotely issuing instructions through a computer (computer, tablet, HMI, etc.), which greatly improves the convenience of switching the same set of production equipment to use different control systems.
