All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flow chart of a solenoid valve debugging method for an arm-type mechanical product provided in an embodiment of the present application. As shown in fig. 1, in an embodiment of the present application, a method for debugging a solenoid valve of an arm type mechanical product is provided, which includes the following steps:
step S11: acquiring an electromagnetic valve debugging instruction, wherein the electromagnetic valve debugging instruction comprises an initial input current parameter of an electromagnetic valve to be debugged;
step S12: loading initial input current to the electromagnetic valve to be debugged according to the initial input current parameters;
step S13: acquiring the action amplitude of a working mechanism controlled by the electromagnetic valve to be debugged detected by detection equipment;
step S14: determining whether the difference value of the action amplitude and the preset amplitude is in an allowable range;
step S15: under the condition that the difference value is determined not to be within the allowable range, adjusting the input current of the electromagnetic valve to be debugged until the difference value is within the allowable range;
step S16: and storing the current input current and the action amplitude corresponding to the current input current.
Specifically, in step S11, the electromagnetic valve debugging instruction may be actively obtained, or the electromagnetic valve debugging instruction sent by a debugging person through a terminal device such as a handheld terminal may be received. In step S12, the initial input current may be any current value, or may be an initial current value determined according to design parameters of the solenoid valve to be debugged, for example, the initial current value may be a current value slightly lower than a lower limit value of a design operating current of the solenoid valve to be debugged. In step S13, the detection device may be installed on the arm-type mechanical product, and specifically may include an attitude sensor, an angle sensor, a pressure transmitter, a vibration sensor, and the like, and when an initial input current is loaded to the solenoid valve to be debugged, the detection device detects an action amplitude of a working mechanism controlled by the solenoid valve to be debugged, and sends the action amplitude to the onboard controller and the handheld terminal through the data acquisition communication unit.

In step S14, the preset amplitude is a standard action amplitude of the working mechanism controlled by the electromagnetic valve to be debugged preset in the handheld terminal, and after the action amplitude of the working mechanism controlled by the electromagnetic valve to be debugged is obtained, the action amplitude is compared with the preset amplitude to determine whether a difference between the two is within an allowable range.

After receiving the rotation angle signal of the arm support, the handheld terminal compares the rotation angle signal of the arm support with a preset rotation angle of the arm support, compares the vibration signal of the arm support with preset vibration of the arm support, and compares the pressure signal of the arm support with preset pressure of the arm support, and respectively determines whether the difference value between the rotation angle signal, the vibration signal and the pressure signal of the arm support and the preset value thereof is within a respective allowable range, when the difference value between any one of the rotation angle signal, the vibration signal and the pressure signal of the arm support and the preset value thereof is not within the corresponding allowable range, it indicates that the current input current cannot meet the debugging requirement of the second electromagnetic valve, the input current (increase or decrease) of the second electromagnetic valve needs to be adjusted, and the above steps are repeatedly executed until the difference value is within the corresponding allowable range, and at this time, it is determined that the current input current is the most suitable drive current of the second electromagnetic valve.
In an alternative or additional embodiment, the electromagnetic valve to be debugged includes a third electromagnetic valve, the third electromagnetic valve is used for controlling the telescopic action of the boom of the arm-type mechanical product, the detection device includes a length sensor, a second vibration sensor and a second pressure transmitter, and the length sensor, the second vibration sensor and the second pressure transmitter are all arranged on the telescopic oil cylinder of the boom.

After the handheld terminal receives the signal, the telescopic length of the telescopic oil cylinder is compared with the preset telescopic length of the telescopic oil cylinder, the vibration signal of the telescopic oil cylinder is compared with the preset vibration of the telescopic oil cylinder, the pressure signal of the telescopic oil cylinder is compared with the preset pressure of the telescopic oil cylinder, whether the difference value between the telescopic length signal, the vibration signal and the pressure signal of the telescopic oil cylinder and the preset value of the telescopic oil cylinder is within the respective allowable range or not is respectively determined, when the difference value between any one of the telescopic length signal, the vibration signal and the pressure signal of the telescopic oil cylinder and the preset value of the telescopic oil cylinder is not within the corresponding allowable range, the current input current cannot meet the debugging requirement of the third electromagnetic valve, the input current (increase or decrease) of the third electromagnetic valve needs to be adjusted, the steps are repeatedly executed until the difference value is within the corresponding allowable range, and the current input current is determined to be the optimal drive current of the third electromagnetic valve.
Referring to fig. 3, fig. 3 is a schematic flow chart illustrating step S15 of the solenoid valve debugging method for arm-type mechanical products according to the embodiment of the present application. In the case that it is determined in step S15 that the difference is not within the allowable range, adjusting the input current of the solenoid valve to be adjusted until the difference is within the allowable range may include the following steps:
step S151: in a case where it is determined that the difference is not within the allowable range, determining whether the difference is greater than zero;
step S152: and under the condition that the difference is larger than zero, reducing the input current of the electromagnetic valve to be debugged by a first preset step length until the difference is in an allowable range.
Specifically, in step S151, when the difference between the motion amplitude and the preset amplitude is not within the allowable range, it is further determined whether the difference is greater than zero. In step S152, when the difference is greater than zero, it indicates that the current input current is too large, at this time, the input current of the solenoid valve to be debugged may be decreased by a first preset step, and the above steps are repeatedly performed until the difference is within the corresponding allowable range. It can be understood that the first preset step may be a fixed step, for example, set to 2mA or 5mA, and the first preset step may also be a variable step, for example, set to 5mA when starting to adjust, and then gradually decrease to 4mA, 3mA, 2mA during the adjustment process, so that when the initial input current is far away from the optimal driving current of the solenoid valve to be debugged, a relatively large step may be used to enable the input current to quickly approach the optimal driving current, and when the input current gradually approaches the optimal driving current, a step that is gradually reduced is used to find the input current that meets the precision requirement, thereby taking efficiency and precision into account during the debugging process.
With reference to fig. 3, based on step S151 and step S152, in the case that the difference value is determined not to be within the allowable range in step S15, the method may further include the following steps:
step S153: and under the condition that the difference value is less than zero, increasing the input current of the electromagnetic valve to be debugged by a second preset step length until the difference value is in an allowable range.
In one embodiment, the first preset step size is equal to the second preset step size.
Specifically, when the difference is smaller than zero, it indicates that the current input current is too small, and at this time, the input current of the solenoid valve to be debugged may be increased by a second preset step length, and the above steps may be repeatedly performed until the difference is within the corresponding allowable range. It can be understood that, similar to the first preset step, the second preset step may be a fixed step, for example, set to 2mA or 5mA, and the second preset step may also be a variable step, for example, set to 5mA when starting to adjust, and then gradually decrease to 4mA, 3mA, or 2mA during the adjustment process, so that, similarly, when the initial input current is far away from the optimal driving current of the solenoid valve to be debugged, the relatively larger step may be used to make the input current quickly approach the optimal driving current, and when the input current gradually approaches the optimal driving current, the step that gradually decreases is used to find the input current that meets the precision requirement, thereby taking efficiency and precision into account during the debugging process.
Referring to fig. 4, fig. 4 is another schematic flow chart of a method for debugging an electromagnetic valve of an arm-type mechanical product according to an embodiment of the present disclosure. As shown in fig. 4, the debugging method may further include the steps of:
step S17: determining whether the current input current reaches a preset termination current;
step S18: and under the condition that the current input current is determined to reach the preset termination current, terminating the debugging of the electromagnetic valve to be debugged and outputting alarm information.
Specifically, the preset termination current is a current value when a fault occurs in the process of loading the input current to the solenoid valve to be debugged, so that any input current loaded to the solenoid valve to be debugged cannot make the difference value between the action amplitude of the controlled working mechanism and the preset amplitude be within the allowable range. Meanwhile, a fault/exception handling log can be generated, so that subsequent debugging personnel can conveniently check the log, and the same fault/exception is prevented from happening again as much as possible.
In one embodiment, the solenoid valve commissioning method further comprises the steps of: and generating an electromagnetic valve debugging report according to the current input current and the action amplitude corresponding to the current input current.
Specifically, after the current debugging of the electromagnetic valve to be debugged is completed, the handheld terminal can forward the current input current and the action amplitude corresponding to the current input current to the background management system through a wireless route, and the background management system receives the action amplitude corresponding to the current input current and then automatically generates an electromagnetic valve debugging report, so that unified informatization and digital management is facilitated, and meanwhile, a tester can conveniently inquire and trace back at any time.
