Description

Technical Field

[0001] This invention relates to the field of actuator control technology, and in particular to an actuator coil control method and control function block. Background Technology

[0002] Cylinders and valves, as basic actuators, are widely used in various automated equipment. As the most common actuators in engineering, they are integrated into non-standard automated equipment and chemical equipment systems as fundamental components. They enable rapid mechanical action and effective pipeline opening and closing, offering advantages such as simple structure and convenient maintenance. Furthermore, their power source is compressed air, eliminating the need for electricity, making them suitable for flammable and explosive production environments, such as those involving the preparation of energetic materials. For highly automated equipment, the control of cylinders and valves requires several basic functions:

[0003] 1. During normal production operation, the control program automatically controls the cylinders and other components according to the specified process flow, enabling multiple cylinders and other components in the equipment to complete the predetermined actions in an orderly and safe manner. Operators can monitor the status of each mechanism in real time through the human-machine interface. During normal production, operators do not have the authority to operate cylinders, valves, or other mechanisms.

[0004] 2. When individual cylinders or hydraulic cylinders of the equipment malfunction such as jamming, under conditions of suspension or other safety assurance, the operator can manually operate the cylinders through the human-machine interface to resolve the malfunction.

[0005] After a fault is resolved, to ensure the equipment continues to operate correctly, each cylinder needs to be manually restored to its pre-fault state. This is to prevent problems such as jamming or impacts caused by incorrect cylinder settings. However, due to operator subjectivity, when handling a fault requires operating multiple cylinders, it is inevitable that some cylinders may be forgotten to be reset to their pre-fault state, posing unforeseen dangers to the safe operation of the equipment.

[0006] Currently, there are two main methods for controlling and operating components such as cylinders and hydraulic cylinders in equipment. One method involves directly controlling the output points of the controller in the main program without judging the process state of the cylinder. The control program calls the required cylinder control points as needed, and the corresponding control point signals are directly associated in the human-machine interface, allowing operators to force control of the cylinder. The other method involves encapsulating the cylinder control program, adding a monitoring function for the cylinder status, and associating the input points of the corresponding function blocks in the human-machine interface to achieve control of the cylinder and other mechanisms.

[0007] Both existing programming methods for cylinders and valves in non-standard automated equipment have certain drawbacks. The first method, which directly controls the controller's output points, only provides cylinder control functionality but lacks cylinder status monitoring. This programming approach does not adhere to basic modular design principles, and for highly automated equipment, it significantly increases the development difficulty of the main program. Therefore, this method is only suitable for simpler automated equipment.

[0008] Another existing programming approach that encapsulates cylinder control adds monitoring of cylinder status and follows modular design principles, making it suitable for programming large-scale automated production equipment. However, its encapsulated functional blocks lack specific anti-misoperation measures. For anti-misoperation functions required for safe production in hazardous environments, these functions need to be programmed individually in the controller's main program and implemented in conjunction with scripts in the human-machine interface. This leads to decreased program readability and inheritance, increased likelihood of program vulnerabilities, and consequently, some unknown security risks. Summary of the Invention

It eliminates the need for individual programming in the controller's main program, thus preserving program readability and inheritance, and reducing the likelihood of program vulnerabilities.

[0056] Furthermore, if the actual action timing time exceeds a preset action time threshold or the positioning detection signal is not in place, it is determined that the actuator has an operational malfunction. The target action includes a setting action and a reset action.

[0057] To facilitate use with existing systems, this application embodiment may also provide a control function block, including an input variable interface group, an input-output variable interface group, and an output variable interface group;

[0058] The input variable interface group includes:

[0072] In practical applications, the variable types that need to be connected to each signal interface can be determined according to the interface type. Specifically, in one implementation, this application embodiment can provide that the function block enable input signal interface, the device pause input signal interface, the cylinder position detection signal input interface in the set state, the cylinder position detection signal input interface in the reset state, the automatic operation trigger signal input interface, the manual operation trigger signal input interface, and the solenoid valve coil mapping output signal interface are all connected to Boolean variables. The device operation mode input signal interface is connected to an integer variable. The cylinder action time setting input interface in the set state and the cylinder action time setting input interface in the reset state are both connected to double integer variables. The cylinder operation status output signal interface is connected to an unsigned integer variable.

[0073] Furthermore, the device pause input signal interface shares the same signal as the main device pause command, and the device operation mode input signal interface shares the same signal as the main device operation mode.

[0074] Furthermore, the cylinder status signals include a cylinder setting action completed signal, a cylinder reset action completed signal, a cylinder setting action operation fault signal, a cylinder reset action operation fault signal, a cylinder setting action in operation signal, a cylinder reset action in operation signal, and a cylinder docking position error signal.

[0075] Combination Figure 2 , Figure 3 , Figure 4 The control function blocks provided in the embodiments of this application will be described in detail.

[0076] The coil control function block interface includes three types: input variable interface, input / output variable interface, and output variable interface. The specific definition and function of the input variable interface are as follows:

[0077] Function block enable input signal EN(1): A Boolean variable needs to be connected to it as the control interface for whether this function block is called in the main program. When the input signal is TRUE, the function block is enabled.

[0078] Device pause input signal Pause(2): A Boolean variable needs to be connected to it as the input interface for the pause command of this function block, so as to realize the pause control of this function block. It usually shares the same signal with the main device pause command. When the input signal is TRUE, the function block pauses.

[0079] The device operation mode input signal nRunMode(3) needs to be connected to an integer variable as the input interface of the operation mode of this function block to realize the setting of the coil operation mode. It usually shares the same signal with the main device operation mode. When the signal variable is equal to 0, the coil is in the jog control mode. When the signal variable is greater than 0, the coil is in the linkage control mode.

[0080] In the set state, the cylinder position detection signal input I_Extend(4) needs to be connected to a Boolean variable as an external detection signal input interface for the cylinder and other actuators to move into position in the coil set state. This is used to detect whether the actuator has moved into position in the set state. When the input signal is TRUE, the actuator has moved into position.

[0081] The cylinder position detection signal input I_Back(5) in the reset state needs to be connected to a Boolean variable as an external detection signal input interface for the cylinder and other actuators to move into position in the coil reset state. This is used to detect whether the actuator has moved into position in the reset state. When the input signal is TRUE, the actuator has moved into position.

[0082] When the cylinder is set, the cylinder action time setting input Time_Extend(6) needs to be connected to a double integer variable as the setting input interface for the time required for the cylinder to move to the position when the coil is set under normal conditions. This is used to set the reasonable running time of the cylinder setting action. When the running time after the cylinder actually performs the setting action is less than the set time, the cylinder setting action is normal. Otherwise, the cylinder setting action is judged to be abnormal.

[0083] The cylinder action time setting input during reset is Time_Back(7); it needs to be connected to a double integer variable as the setting input interface for the time required for the cylinder to move to the position when the coil is reset under normal conditions, so as to realize the setting of the reasonable running time of the cylinder reset action. When the running time after the cylinder actually performs the reset action is less than the set time, the cylinder reset action is normal; otherwise, the cylinder reset action is judged to be abnormal.

[0084] The specific definitions and functions of the input / output variable interface are as follows:

[0085] Automatic operation trigger signal StartFlag_A(8): It needs to be connected to a Boolean variable as the input interface of the coil start trigger signal in the linkage mode. This signal is applied to the automatic control program of the main equipment to realize the coil control trigger during normal production operation. When the signal is TRUE, the solenoid valve coil is energized.

[0086] Manual run trigger signal StartFlag_M(9): A Boolean variable needs to be connected to it as the input interface for the coil start trigger signal when the jog mode or the linkage mode is paused. This signal is directly associated with the button on the operation interface to realize the manual control trigger of the coil in the jog mode or the linkage mode paused state. When this signal is TRUE, the solenoid valve coil is energized.

[0087] The specific definition and functions of the output variable interface are as follows:

[0088] The output signal Q(10) of the solenoid valve coil needs to be connected to a Boolean variable as the output interface of the function block control instruction. It is connected to the hardware mapping address of the controller output variable that controls the solenoid valve coil in order to realize direct control of the coil.

[0089] Cylinder running status output signal Status_Out(11): It needs to be connected to an unsigned integer variable as the output interface of the function block status signal to realize the real-time output of the cylinder status signal. The function block defines 7 cylinder running states, namely, cylinder setting action in place (signal = 1), cylinder reset action in place (signal = 2), cylinder setting action operation failure (signal = 3), cylinder reset action operation failure (signal = 4), cylinder setting action in operation (signal = 5), cylinder reset action in operation (signal = 6), cylinder docking position error (signal = 100). The main program of the equipment can read the status signal in real time and respond according to the specific process requirements.

[0090] Function block enable output signal ENO(12): Function block enable output interface, which does not need to be connected to actual variables.

[0091] The specific design method of the user interface used in conjunction with this function block is as follows:

[0092] The dedicated operation window for coil control includes two operation buttons, two position indicator lights, and a running status display text bar. The specific functions of each component are described below:

[0093] Set (13): Set button, associated with the manual run trigger signal StartFlag_M (9), used to realize the manual set trigger of the coil in the paused state of jog mode or linkage mode, so that the solenoid valve coil is energized;

[0094] Reset (14): Reset button, associated with the manual run trigger signal StartFlag_M (9), is used to realize the manual reset trigger of the coil in the paused state of jog mode or linkage mode, so that the solenoid valve coil is de-energized;

[0095] Position in place (15): Indicator light, associated with the cylinder position detection signal input signal I_Extend (4) in the position state, used to realize the real-time display of the cylinder position action operation position detection sensor status;

[0096] Reset in place (16): Indicator light, associated with the cylinder position detection signal input signal I_Back (5) in the reset state, used to realize the real-time display of the cylinder reset action operation position detection sensor status;

[0097] Status display text box (17): Data output box, associated with the cylinder operating status output signal Status_Out (11), used to realize the real-time display of the cylinder operating status.

[0098] The operation flow and usage instructions for the coil control program and user interface are as follows:

[0099] When the function block enable input signal EN(1) is TRUE, the control program divides the coil control into two modes according to the running mode signal nRunMode(3): jog control mode and linkage control mode, in order to meet the requirements of the production process.

[0100] Jog control mode: When nRunMode(3) equals 0, it is jog control mode. At this time, the manual run trigger signal StartFlag_M(9) is valid. The operator can directly control the coil through the button in the operation interface. When the set position (13) button is pressed, the manual run trigger signal StartFlag_M(9) is TRUE. The cylinder performs the set position action and starts the timer. When the action time reaches the set position, the cylinder action time setting Time_Extend(6) is checked. The status of the cylinder position detection I_Extend(4) is checked. When the signal is TRUE, the cylinder moves normally to the position. The cylinder running status output signal Status_Out(11) is assigned a value of 1. When the signal is FALSE, the cylinder does not move to the position within the specified time. The cylinder running status output signal Status_Out(11) is assigned a value of 3, which means that the cylinder has failed to perform the set position action. The operator is prompted to take appropriate action. When the reset (14) button is pressed, the manual operation trigger signal StartFlag_M (9) is FALSE, the cylinder performs the set action and starts the timer. When the action time reaches the reset cylinder action time setting Time_Back (7), the status of the cylinder position detection I_Back (5) is checked. When the signal is TRUE, the cylinder moves normally to the position and the cylinder operation status output signal Status_Out (11) is assigned a value of 2. When the signal is FALSE, the cylinder does not move to the position within the specified time and the cylinder operation status output signal Status_Out (11) is assigned a value of 4, which means that the cylinder has failed to perform the reset action and prompts the operator to take appropriate action.

[0101] Linkage control mode: When nRunMode(3) is greater than 0, it is the linkage control mode. In this mode, according to the state of the device pause input signal Pause(2), there are two situations: paused state and non-pause state.

[0102] Interlocking control mode pause state: When nRunMode(3) is greater than 0 and the equipment pause input signal Pause(2) is TRUE, the control program enters the interlocking control mode pause state. At this time, the manual run trigger signal StartFlag_M(9) is valid, and the operator can directly control the coil through the buttons in the operation interface. This mode is usually used for fault handling operations during normal production operation of the equipment. The specific operation process is the same as the jog control mode. In this mode, when the equipment recovers from the pause state to normal operation, the operator should restore the cylinder state to the final state when the fault occurred. Otherwise, the cylinder running status output signal Status_Out(11) is assigned a value of 100, which means that the cylinder docking position is incorrect and the equipment is not allowed to resume operation.

[0103] Non-pause state in linkage control mode: When nRunMode(3) is greater than 0 and the equipment pause input signal Pause(2) is FALSE, the control program enters the normal production state of linkage control mode. At this time, the automatic run trigger signal StartFlag_A(8) is valid, the button trigger function of the operation interface is disabled, the human-machine interface is closed, and the coil is automatically controlled by the control program. This mode can avoid the influence of human factors on process stability during production and improve the stability and safety of automatic operation of the system.

[0104] Taking a tooling positioning mechanism as an example, the system requires that when the material arrives at the positioning mechanism, the positioning cylinder extends to position the material. After the positioning is completed and the cylinder retracts, the material can continue to be conveyed to the next station. If the cylinder action is abnormal due to material jamming or other reasons during the extension or retraction process, the operator can change the working state of the cylinder and manually intervene in the material through the cylinder jog button on the operation interface after the system enters the pause state, until the fault is successfully resolved and the system continues to run.

[0105] The specific program design and workflow are as follows:

[0106] 1. Edit the positioning cylinder control function block and operation interface: EN(1) is forced to TRUE, Pause(2) is associated with the system main pause signal, nRunMode(3) is associated with the system running mode signal, I_Extend(4) is associated with the positioning cylinder extension detection, I_Back(5) is associated with the positioning cylinder retraction detection, Time_Extend(6) is set to 5s, Time_Back(7) is set to 5s, StartFlag_A(8) is associated with the positioning cylinder control variable used in the automatic control program, StartFlag_M(9) is associated with the positioning cylinder manual control variable, Q(10) is associated with the control output point of the positioning cylinder coil, Status_Out(11) is associated with the positioning cylinder status variable, Set(13) and Reset(14) are both associated with the positioning cylinder manual control variable, Set in place(15) is associated with the positioning cylinder extension detection, Reset in place(16) is associated with the positioning cylinder retraction detection, Status display text box(17) is associated with the positioning cylinder status variable.

[0107] 2. Actual working process: When nRunMode(3) is set to be greater than 0, the system is in the linkage working mode. When the material arrives at the positioning mechanism, StartFlag_A(8) is set to TRUE. The positioning cylinder performs the extension action. When the cylinder running time reaches 5s set by Time_Extend(6), it is judged whether I_Extend(4) has received the extension to position signal. If the position signal is triggered, Status_Out(11) is set to 1. The positioning of the material is completed. StartFlag_A(8) is set to FALSE. The positioning cylinder performs the retraction action. When the cylinder running time reaches 5s set by Time_Back(7), it is judged whether I_Back(5) has received the retraction to position signal. If the position signal is triggered, Status_Out(11) is set to 2. The system continues to run and transport the material to the next station.

[0108] 3. During this process, if the positioning cylinder fails to extend or retract properly, Status_Out(11) will be assigned a value of 3 or 4, and the cylinder will remain in its current position. At this time, the operator presses the system pause button, and the system enters a paused state. The operator finds the problem, confirms the cause of the fault, and manually controls the cylinder by clicking the control button on the operation interface to restore the positioning cylinder's operation. If the stopping position of the positioning cylinder is inconsistent with the stopping position when the fault occurred, Status_Out(11) will be assigned a value of 100, indicating that the cylinder's stopping position is incorrect. At this time, the operator needs to restore the positioning cylinder to its correct position before the system can resume operation.

[0109] Adopting a modular design concept, this system enables safe control and status monitoring of single-electrified coils, making it easily applicable to coil control in various non-standard equipment. Coil control is divided into three different scenarios: inching control, paused state in linkage control, and non-pause state in linkage control. Different control methods are assigned to the coils for each scenario. Two different variables, manual and automatic, are used to control the coil's output point. By distinguishing between manual and automatic control based on specific application scenarios, human error can be effectively avoided. The state of the coil-controlled cylinder is finely divided into five states, facilitating separate access and processing by the system's linkage program and operators for each state. A cylinder docking position detection function is designed to prevent safety hazards caused by sudden system startup when the cylinder is docked in an incorrect position. The coil operation buttons in the user interface are separated from the coil control variables in the automatic control program, eliminating the impact of human factors on process stability and improving the stability and safety of the system's automatic operation.

[0110] In summary, the control function block provided in this application uses two different variables—manual and automatic—to control the coil control output point. It also distinguishes the coil operation buttons in the user interface from the coil control variables in the automatic control program, effectively avoiding human error and improving the stability and safety of the system's automatic operation. It provides a cylinder docking position detection function, preventing safety hazards caused by sudden system startup when the cylinder is docked in an incorrect position. Adopting a modular design, it enables safe control and status monitoring of single-electrified coils, and can be easily applied to coil control in various non-standard equipment.
