Detailed Description
To further illustrate the technical measures and effects taken by the present invention to achieve the intended objects, embodiments of the present invention will be described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below are only a part of the embodiments of the present invention, and not all of them. All other embodiments, which can be obtained by a person skilled in the art based on the embodiments of the present invention without any creative effort, belong to the protection scope of the embodiments of the present invention. While the present invention has been described in connection with the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but is intended to cover various modifications, equivalent arrangements, and specific embodiments thereof.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating an automatic flow monitoring method according to an embodiment of the present invention. As shown in fig. 1, the method of this embodiment, which may be applied to a controller, includes the steps of:
step S11: acquiring the actual position number of the actuator;
in one embodiment, step S11: acquiring an actual position number of an actuator, comprising: receiving sensing position information sent by a sensor or a servo encoder; and when the sensing position number corresponding to the sensing position information is matched with the preset position number, storing the sensing position number into the actual position register.
In one embodiment, step S11: acquiring an actual position number of an actuator, comprising: and when the sensing position number corresponding to the sensing position information is not matched with the preset position number, carrying out alarm response of position error.
The preset position number may be a number of positions where all nodes of the actuator in a certain process are located, which is stored in advance. For example, the preset position numbers may include a first position number a, a second position number B, and the like. When the sensing position number corresponding to the sensing position information matches the preset position number, for example, the sensing position number is a, the sensing position number is stored as the actual position number in the actual position register.
Specifically, the actuator may be, for example, a servo motor, an air cylinder, or the like that performs a preset operation.
In one embodiment, when the actuator is a servo motor, the number of the sensing position of the actuator is determined by a servo encoder. Specifically, after the servo motor action is completed, the servo encoder feeds back sensing position information to the controller through EtherCAT communication, the controller obtains a sensing position number after processing the position deviation bandwidth, so that feedback pulse jitter of the servo motor encoder is prevented, and the sensing position number is stored in an actual position register as an actual position number when the sensing position number is matched with a preset position number.
In one embodiment, when the actuator is a cylinder, the actual position number of the cylinder may be determined by the initial position sensor and the active position sensor. Wherein, the initial position sensor and the action position sensor are respectively used for detecting that the air cylinder is at an initial position and an action position. After the action of the cylinder is finished, if the cylinder is at an initial position, the initial position sensor senses the cylinder, the normally open contact is closed, a first electric signal in the sensing position information is input through the input end of the controller, and the initial position sensor is 1; if the cylinder is in the action position, the action position sensor senses the cylinder, the normally open contact is closed, a second electric signal in the sensing position information is input through the input end of the controller, and the action position sensor is 1.
Step S12: determining and storing a corresponding memory position number according to the actual position number;
in one embodiment, as shown in fig. 2, step S12: determining and storing a corresponding memory position number according to the actual position number, wherein the memory position number comprises the following steps:
step S121: clearing the memory position register;
step S122: driving an actuator to a target position;
step S123: acquiring a current actual position number;
step S124: and when the current actual position number is matched with the target position, the current actual position number is used as a memory position number and is stored in the memory position register.
Specifically, in one embodiment, when the actuator is actuated, the process may proceed to step S121: and clearing the memory position register. After the actuator action is completed, the process may proceed to step S123: the current actual position number is acquired. The specific method for acquiring the current actual position number may refer to the related description of step S11, which is not described herein again. The current actual position number of the actuator is continuously updated in accordance with the operation performed by the actuator.
Specifically, for example, after the target position is written into the actuator driver, the controller executes the driver to drive the actuator to the target position, and after the action is completed, obtains the current actual position number of the actuator, and determines whether the actual position number matches the target position, and if the actual position number does not match the target position (i.e., the actual position is not the target position), an alarm message may be output, for example, an alarm message that the actuator has not reached the target position may be output through a pop-up window. In addition, after the operator manually drives the actuator to the target position, whether the actual position number matches the target position may be determined again. When the actual position number is matched with the target position, the controller stores the current actual position number as a memory position number in the memory position register. Specifically, the memory location register may be a power-off hold register, so that when the power-off is stopped due to an unexpected power-off and the power is turned on again, the automatic action location (i.e., the memory location number) memorized before the power-off can be obtained.
Step S13: when the current actual position number is not matched with the current memory position number, performing alarm response;
specifically, in one embodiment, the process may proceed to step S13 when the current memory location number is not 0.
Specifically, step S13: when the current actual position number is not matched with the current memory position number, the alarming response comprises the following steps: and when the current memory position number in the memory position register is not matched with the current actual position number in the actual position register and the actuator is in a non-manual debugging state, alarming response is carried out.
In one embodiment, as shown in fig. 3, step S13: when the current actual position number is not matched with the current memory position number, the alarming response comprises the following steps:
step S131: judging whether the current actual position number is matched with the current memory position number;
when the current actual position number matches the current memory position number, the process proceeds to step S132: setting a correct position flag to 1;
step S133: no alarm response is made;
step S134: when the current actual position number is not matched with the current memory position number, setting a correct position flag to be 0;
step S135: judging whether the actuator is in a manual debugging state or not;
when the actuator is in the manual debug state, the process proceeds to step S133: no alarm response is made;
when the actuator is in the non-manual debugging state, step S136: and carrying out alarm response.
In one embodiment, step S13: when the current actual position number is not matched with the current memory position number, the alarm responding step comprises the following steps:
all abnormal states are relieved, and after a reset signal is received, the alarm response is stopped.
Specifically, in an embodiment, after the alarm response is performed, the operator needs to first switch the automatic process monitoring device to a manual debugging state, and then manually operate the corresponding actuator according to the alarm information, for example, the content prompted by the device panel, in a safe sequence, so as to drive the actuator to the prompted position (i.e., the position corresponding to the memorized position number in the memorized position register). After the operator finishes driving, pressing a reset button to relieve the alarm state; if the alarm is released after the reset button is pressed, the process is ended; if the alarm still exists, judging whether other types of alarms exist; if the alarm of other categories exists, the reset button is pressed again after the alarm is processed; if there is no other type of alarm, it means that when the alarm may be released, the other actuator is operated so as not to be located at the position memorized in the automatic flow (that is, the position corresponding to the memory position number in the memory position register corresponding to the actuator), and at this time, the actuator is operated according to the prompt and then the reset button is pressed to release the alarm state.
Referring to fig. 4, fig. 4 is a block diagram illustrating an automatic flow monitoring apparatus according to an embodiment of the present invention. As shown in fig. 4, the automatic process monitoring apparatus of this embodiment includes: controller 40, alarm response device 41.
The controller 40 is used for acquiring the actual position number of the actuator, and determining and storing the corresponding memory position number according to the actual position number. The alarm response device 41 is used for carrying out alarm response when the current actual position number is not matched with the current memorized position number.
In one embodiment, the controller 40 includes an actual location register and a memory location register. The actual position register is a common register, and the memory position register is a power-off holding type register, so that after the power-off and the shutdown are accidentally performed, the automatic action position memorized before the power-off (namely the position corresponding to the memory position number) can be obtained when the power is supplied again.
In one embodiment, alarm response device 41 may include, but is not limited to, a display for displaying alarm information.
The invention also provides automatic process monitoring equipment which comprises a memory and a processor, wherein the memory is stored with a computer program, and the processor can realize the automatic process monitoring method when executing the computer program.
