Referring to fig. 1, a method flow of the cylinder expansion and contraction adjustment control method comprises the following steps:

step S100: and acquiring target travel information, initial travel information and initial air quantity information.

The stroke corresponding to the target stroke information is a movement stroke of the piston in the cylinder body, for example, the piston rod of the cylinder needs to extend for 3 cm, the stroke corresponding to the target stroke information is 3 cm, and the corresponding numerical value is input by a worker through a key or a mobile device in wireless connection, and the specific mode is set by the worker according to the actual situation, which is not described again; the stroke value corresponding to the initial stroke information is the moving stroke of the piston in the cylinder body when the corresponding target stroke is not input by a worker, the stroke parameter of the last cylinder movement can be obtained to obtain the stroke value, the gas volume value corresponding to the initial gas amount information is the gas volume value required to be provided and maintained when the stroke corresponding to the initial stroke information is performed by the piston, and the gas can be obtained by monitoring the gas supplied by the device for supplying gas to the cylinder.

Step S101: and performing difference calculation according to the target travel information and the initial travel information to determine required travel information.

And the stroke value corresponding to the required stroke information is the distance value which needs to be moved by the piston under the current condition, and the stroke value corresponding to the initial stroke information is subtracted from the stroke value corresponding to the target stroke information and absolute value calculation is carried out to determine the stroke value.

Step S102: and performing matching analysis according to the target travel information and the required air quantity information stored in the preset air quantity database to determine the required air quantity information corresponding to the target travel information.

The gas volume value corresponding to the required gas volume information is a gas volume value required to be provided when the sealing inside the cylinder is normal and the friction is normal and the stroke value corresponding to the target stroke information of the piston movement, the corresponding relation between the gas volume value and the required gas volume value is determined by a worker through multiple tests in advance, and a gas volume database is established according to the corresponding relation between the gas volume value and the required gas volume value, wherein the establishing method of the gas volume database is a conventional technical means of the worker in the field and is not repeated.

Step S103: and performing difference calculation according to the required gas amount information and the initial gas amount information to determine difference gas amount information.

The gas volume value corresponding to the difference gas quantity information is a gas volume value which needs to be provided for the interior of the cylinder or a gas volume value which needs to be recovered from the cylinder under the current condition, a value corresponding to the initial gas quantity information is subtracted from a value corresponding to the required gas quantity information to determine, and when the value corresponding to the difference gas quantity information is a negative value, the fact that gas needs to be recovered from the cylinder is indicated.

Step S104: and controlling air inlet equipment connected with an air inlet of the air cylinder to operate according to the air quantity corresponding to the difference air quantity information, and acquiring the stroke information and the added air quantity information of the piston in real time in the operation process.

The air inlet device is communicated with the interior of the cylinder to supply air, and can be formed by combining an air supply device and a proportional control valve, so that the air can be input into the cylinder according to a required proportion; the value corresponding to the piston stroke information is a real-time moving stroke value in the moving process of the piston, and can be obtained by installing a displacement sensor for detecting the displacement condition of the piston in the cylinder, wherein the displacement sensor can be an infrared displacement sensor or a reluctance type displacement sensor, and is set by a worker according to the actual condition without repeated description; the air volume value corresponding to the added air volume information is the air volume value provided for the cylinder by the air intake device or recovered from the cylinder after the piston starts to move.

Step S105: and performing difference calculation according to the piston stroke information and the initial stroke information to determine the moving stroke information.

The stroke value corresponding to the moving stroke information is the displacement value moved in the moving process of the piston, and the value corresponding to the initial stroke information is subtracted from the value corresponding to the piston stroke information to calculate an absolute value so as to determine the absolute value.

Step S106: and performing matching analysis according to the movement travel information, the added air volume information and the influence coefficient information stored in the preset influence database to determine the influence coefficient information corresponding to the added air volume information under the movement travel information.

The value corresponding to the influence coefficient information is a value of the influence degree of the reaction gas on the piston moving operation, and is set according to the actual conditions of the piston displacement condition and the gas amount adding condition, for example, in a normal condition, the piston can move by 1cm by adding one unit volume of gas, and the influence coefficient is 0.9 by adding one unit volume of gas only by 0.9cm by currently adding one unit volume of gas, the specific corresponding relationship of the three is determined by a worker through a test in advance, and the establishment of the influence database is performed so as to facilitate the subsequent searching of the data of the three, and the establishment method of the database is a conventional technical means of the worker in the field and is not described in detail.

Step S107: and determining corrected air quantity information according to the influence coefficient information and the required stroke information, and updating the corrected air quantity information into new difference air quantity information until the stroke value corresponding to the piston stroke information is consistent with the stroke value corresponding to the target stroke information and the movement is stopped.

The numerical value corresponding to the corrected gas amount information is a gas volume value which is obtained according to the front movement condition of the piston and can move the piston to a target position, the influence coefficient information and the required stroke information are used for searching an influence database, and the corrected gas amount information is updated to be new difference gas amount information at the moment, so that the total gas amount required to be added by the gas supply equipment can be fed back and modified according to the movement condition of the piston, the gas supply amount can be modified in real time in the movement process of the piston, the piston can move to the stroke value corresponding to the target stroke information and stop moving, and the overall telescopic effect of the cylinder is better; the update frequency of the difference gas amount information is set by the staff according to the actual situation, and is not described in detail.

Referring to fig. 2, the cylinder telescopic adjustment control method further includes:

step S200: and performing difference calculation according to the corrected gas amount information and the corresponding non-updated difference gas amount information to determine the deviation gas amount information, wherein the value corresponding to the deviation gas amount information is the value corresponding to the corrected gas amount information minus the value corresponding to the non-updated difference gas amount information.

And the gas value corresponding to the deviation gas quantity information is a difference value before and after the difference gas quantity information is updated, and the value corresponding to the difference gas quantity information which is not updated is subtracted from the value corresponding to the determined correction gas quantity information to determine.

Step S201: and judging whether the absolute value of the numerical value corresponding to the deviation air quantity information is larger than a preset normal value or not.

The normal value is the maximum value set by the operator when the gas quantity is determined not to have a large change, and the purpose of judgment is to know whether the difference gas quantity has a large change when being updated currently.

Step S2011: and if the absolute value of the numerical value corresponding to the deviation air quantity information is not larger than the normal value, defining a normal point according to the piston stroke information.

When the absolute value of the numerical value corresponding to the deviation air quantity information is not larger than the normal value, the numerical value of the air supply equipment is not changed greatly, the position to which the piston moves is normal at the moment, the position of the piston is determined in the air cylinder according to the piston stroke information at the moment, and therefore the position is defined as a normal point to be identified, and different positions in the air cylinder are distinguished.

Step S2012: if the absolute value of the numerical value corresponding to the deviation air quantity information is larger than the normal value, defining an abnormal point according to the piston stroke information.

When the absolute value of the numerical value corresponding to the deviation air quantity information is larger than the normal value, the numerical value of the air supply device is indicated to have larger change, the position to which the piston moves at the moment is indicated to be abnormal, the position of the piston is determined in the cylinder according to the piston stroke information at the moment, and therefore the position is defined as an abnormal point to be identified, and different positions in the cylinder are distinguished.

Step S202: and when the stroke value corresponding to the piston stroke information is consistent with the stroke value corresponding to the target stroke information, counting according to the normal points to determine the normal quantity information, and counting according to the abnormal points to determine the abnormal quantity information.

When the stroke value corresponding to the piston stroke information is consistent with the stroke value corresponding to the target stroke information, the piston is finished, and the condition of the path moved by the piston can be analyzed; the number value corresponding to the normal number information is the total number value of the normal points in the piston moving process and is obtained by counting the normal point identification, and the number value corresponding to the abnormal number information is the total number value of the abnormal points in the piston moving process and is obtained by counting the abnormal point identification.

Step S203: and calculating according to the normal quantity information and the abnormal quantity information to determine sum quantity information, and calculating according to the abnormal quantity information and the sum quantity information to determine abnormal proportion information.

The numerical value corresponding to the sum quantity information is the total numerical value of the normal points and the abnormal points generated in the moving process of the piston, and the numerical value corresponding to the normal quantity information and the numerical value corresponding to the abnormal quantity information are obtained; the numerical value corresponding to the abnormal proportion information is the proportion value of the abnormal point in all the point positions, and the numerical value corresponding to the abnormal quantity information is divided by the numerical value corresponding to the total quantity information to determine the abnormal proportion information.

Step S204: and judging whether the value corresponding to the abnormal proportion information is larger than a preset allowable sealing value or not.

The allowable sealing value is the minimum ratio of abnormal points when the operator sets that the sealing in the cylinder is judged to have great abnormality, and the purpose of judgment is to know whether the sealing condition in the cylinder has great abnormality.

Step S2041: and if the numerical value corresponding to the abnormal proportion information is larger than the allowable sealing value, outputting an abnormal sealing signal.

When the numerical value corresponding to the abnormal proportion information is larger than the allowable sealing value, the fact that larger sealing abnormality exists in the air cylinder is indicated, and an abnormal sealing signal is output to mark the situation, so that a worker can know the situation in time and carry out follow-up maintenance treatment.

Step S2042: and if the numerical value corresponding to the abnormal proportion information is not greater than the allowable sealing value, outputting a to-be-determined sealing signal.

When the numerical value corresponding to the abnormal proportion information is not larger than the allowable sealing value, the number of abnormal points which can appear in the cylinder is small, the generated abnormal points are possibly caused by uneven friction and also possibly caused by defects of the side wall of the cylinder body, and the undetermined sealing signal is output to mark the situation so that a worker can know the situation to facilitate subsequent further analysis and processing.

Referring to fig. 3, after the abnormal sealing signal is output, the cylinder expansion and contraction adjustment control method further includes:

step S300: and forming a point location coordinate axis according to the normal point and the abnormal point, and establishing a virtual detection interval with a width of a preset fixed value at the end point of the point location coordinate axis.

The point location coordinate axis is a coordinate axis obtained by connecting all normal points and abnormal points, the orientation of the coordinate axis is consistent with the moving direction of the piston rod when the piston rod extends out, the fixed value is a fixed value set by an operator, the virtual detection interval is an interval for carrying out data acquisition on each normal point and each abnormal point on the point location coordinate axis, the end point of the point location coordinate axis is a normal point or an abnormal point closest to the rod outlet of the cylinder, and the virtual detection interval is set towards the direction of the starting point in the point location coordinate axis.

Step S301: and judging whether the travel value corresponding to the required travel information is smaller than a fixed value.

The purpose of the judgment is to know whether the range of the current piston movement is small or not so as to facilitate subsequent analysis.

Step S3011: and if the stroke value corresponding to the required stroke information is smaller than a fixed value, outputting a sealing damage signal.

When the stroke value corresponding to the required stroke information is smaller than a fixed value, the fact that the moving range of the current piston is small, an abnormal point with a high proportion appears in the small range is shown, the situation that a sealing ring on the piston is damaged probably exists, and a sealing damage signal is output to mark the situation so as to facilitate subsequent processing of a worker.

Step S3012: and if the stroke value corresponding to the required stroke information is not less than the fixed value, outputting a re-analysis signal.

When the stroke value corresponding to the required stroke information is not less than the fixed value, the moving range of the piston is wide, and at the moment, the piston needs to be further analyzed according to the conditions of the abnormal point and the normal point, so that a re-analysis signal is output to identify the condition, and the subsequent further processing is facilitated.

Referring to fig. 4, after analyzing the signal output again, the cylinder telescopic adjustment control method further includes:

step S400: counting according to the abnormal points in the virtual detection interval to determine the influence quantity information, and calculating according to the influence quantity information and the abnormal quantity information to determine the influence ratio information.

The value corresponding to the influence quantity information is a total quantity value of the abnormal points in the virtual detection interval, the number of the abnormal points in the virtual detection interval is obtained, the value corresponding to the influence proportion information is a proportion value of the quantity of the abnormal points in the virtual detection interval to all the abnormal points, and the value corresponding to the influence quantity information is subtracted from the value corresponding to the influence quantity information to determine the quantity.

Step S401: and judging whether the numerical value corresponding to the influence ratio information is larger than a preset extrusion influence value or not.

The extrusion influence value is a minimum influence ratio value set by a worker and used for determining that most abnormal points exist in a part, close to the rod outlet, of a piston moving path, and the judgment purpose is to know whether most abnormal points exist in the part, close to the rod outlet, in the piston moving process so as to facilitate subsequent analysis.

Step S4011: and if the numerical value corresponding to the influence ratio information is not greater than the extrusion influence value, outputting a sealing damage signal.

When the numerical value corresponding to the influence ratio information is not greater than the extrusion influence value, it is described that most abnormal points occurring in the moving process of the piston are not located in the part, close to the rod outlet, of the moving path, namely, the situation that the sealing effect is poor due to the fact that the piston extrudes one side wall of the cylinder body due to the fact that an executing element connected to the piston rod is too heavy does not exist, namely, more abnormal points occurring in the moving process of the piston are caused by poor sealing of the inside of the cylinder, and at the moment, a sealing damage signal is output to mark the situation, so that a worker can timely know the inside situation of the cylinder body and correspondingly process the inside situation.

Step S4012: and if the numerical value corresponding to the influence occupation ratio information is larger than the extrusion influence value, acquiring element weight information of a preset execution element, and judging whether the weight value corresponding to the element weight information is smaller than a preset upper limit weight value.

When the value corresponding to the influence occupation ratio information is larger than the extrusion influence value, the situation that most abnormal points occurring in the moving process of the piston are positioned in a part, close to a rod outlet, of a moving path exists, at this time, an executing element connected to the piston rod is too heavy, so that the piston extrudes one side wall of the cylinder body, and the sealing effect is poor, and further analysis is needed; the weight value corresponding to the element weight information is the weight value of the actuator connected to the end of the piston rod, and can be determined by the mass input by a worker when the actuator is connected, or a gravity sensor can be installed at the connection position of the piston rod and the actuator to obtain the weight value, and the specific mode is set by the worker according to the actual situation, which is not described in detail; the upper limit weight value is the minimum weight value of the actuating element when the piston possibly presses the side wall of the cylinder body, which is set by an operator, and the purpose of judgment is to know whether most abnormal points are caused by the overweight of the actuating element.

Step S40121: and if the weight value corresponding to the element weight information is smaller than the upper limit weight value, outputting a sealing damage signal.

When the weight value that component weight information corresponds is less than upper limit weight value, it makes piston extrusion cylinder body lateral wall so that the not good condition of cylinder body internal seal to show that there is not execute component, and the cylinder body is inside to appear sealed unusual promptly, and the sealed damage signal of output is in order to sign this condition this moment to make the staff can in time learn the inside condition of cylinder body and correspond the processing.

Step S40122: and if the weight value corresponding to the element weight information is not less than the upper limit weight value, outputting an overweight influence signal.

When the weight value corresponding to the element weight information is not less than the upper limit weight value, it is indicated that the currently connected executing element may cause the piston to extrude the side wall of the cylinder body, so that the sealing effect inside the cylinder body is not good, and at the moment, an overweight influence signal is output to enable a worker to know the situation, so that the worker can conveniently adjust subsequent parts.

Referring to fig. 5, when the weight value corresponding to the element weight information is not less than the upper limit weight value, the cylinder telescopic adjustment control method further includes:

step S500: and calculating according to the element weight information and the preset influence pressure information to determine the proportion information.

The pressure value corresponding to the influence pressure information is the minimum extrusion force value set by a worker and used for determining that the piston can extrude the side wall of the cylinder body so as to change the sealing effect, the gravity value generated by the element can be determined according to the element weight information, the value corresponding to the proportion information is the proportion value between the element gravity value and the extrusion force value, and the value corresponding to the element weight information is divided by the value corresponding to the influence pressure information so as to determine the value.

Step S501: and calculating according to the proportion information and the length of a preset piston rod to determine length information in the cylinder, and calculating a difference value according to the length information in the cylinder and the total length of a cavity of a preset cylinder body to determine a dividing point.

The length of the piston rod is the total length of the piston rod in the cylinder, the value corresponding to the length information in the cylinder is the length value of the piston rod in the cylinder when the sealing effect is not good due to overlarge extrusion force, the length ratio of the piston rod in the cylinder to the length of the piston rod outside the cylinder can be determined according to the proportion information and the condition of a moment formula, and the length distribution can be carried out according to the length of the piston rod; the total length of the cavity of the cylinder body is the distance from one end, far away from the actuating element, of the space in the cylinder, where the piston can move, to the boundary line between the inside and the outside of the cylinder, and the critical point, which influences the sealing performance of the cylinder due to the extrusion of the piston in the cylinder, can be determined according to the length information in the cylinder and the total length of the cavity in the cylinder, so that the point is defined as a boundary point for identification, and subsequent analysis is facilitated.

Step S502: and defining an abnormal point between the end point and the demarcation point of the virtual detection interval as a stress point in the virtual detection interval, and counting according to the stress point to determine stress quantity information.

The abnormal point which is in the virtual detection interval and is between the end point and the dividing point of the virtual detection interval is probably generated by piston extrusion due to overlarge weight of the actuating element, and the abnormal point is defined as a stress point for identification so as to realize the differentiation of different abnormal points; the numerical value corresponding to the stress quantity information is the total numerical value of the stress points, and can be obtained by counting the conditions when the stress points are defined one by one.

Step S503: and calculating according to the stress quantity information and the influence quantity information to determine stress ratio information.

And the numerical value corresponding to the stress ratio information is a ratio value of the stress point to all abnormal points in the virtual detection interval, and is determined by dividing the numerical value corresponding to the stress quantity information by the numerical value corresponding to the influence quantity information.

Step S504: and judging whether the numerical value corresponding to the stress ratio information is larger than a preset critical value or not.

The critical value is the minimum value of the ratio of the stress points when the operator determines that a large number of abnormal points appear in the virtual detection interval and are caused by the overweight of the actuating element, and the purpose of judgment is to know whether the large number of abnormal points in the current virtual detection interval are caused by the overweight of the actuating element.

Step S5041: and if the numerical value corresponding to the stress ratio information is larger than the critical value, outputting an overweight influence signal.

When the value corresponding to the stress ratio information is larger than the critical value, it is described that the reason that a large number of abnormal points appear in the virtual detection interval is overweight of the executing element, and an overweight influence signal is output at the moment to identify the situation, so that a worker can know the situation in time to facilitate subsequent processing.

Step S5042: and if the numerical value corresponding to the stress ratio information is not greater than the critical value, outputting a sealing damage signal.

When the numerical value corresponding to the stress ratio information is not larger than the critical value, it is described that the abnormal point appearing in the current virtual detection interval is not caused by the overweight of the execution element, namely the reason that more abnormal points appear is only possible to be the problem of the internal seal of the cylinder, and at the moment, a seal damage signal is output to identify the situation so as to facilitate timely processing of a worker.

Referring to fig. 6, after the signal to be sealed is output, the cylinder telescopic adjustment control method further includes:

step S600: and judging whether the value corresponding to the deviation air quantity information of the abnormal point is larger than zero.

After the undetermined sealing signal is output, it is shown that the number of abnormal points on the moving path of the piston is small, the problem of sealing on the piston does not exist, at this time, the abnormal points are possibly caused by uneven friction and also possibly caused by the defect of the side wall of the cylinder body of the cylinder, and further analysis is needed; the purpose of the judgment is to know whether the amount of gas currently being corrected is to be added upward or decreased downward.

Step S6001: and if the value corresponding to the deviation air quantity information of the abnormal point is larger than zero, defining the abnormal point as an abnormal increment point.

When the value corresponding to the deviation air quantity information of the abnormal point is larger than zero, the volume of the gas needing to be processed is increased after the piston moves from the abnormal point, and the abnormal point is defined as an abnormal increment point for identification, so that different abnormal points can be distinguished conveniently.

Step S6002: and if the value corresponding to the deviation air quantity information of the abnormal point is not more than zero, defining the abnormal point as an abnormal decrement point.

When the value corresponding to the deviation air quantity information of the abnormal point is not more than zero, the volume of the gas needing to be processed is reduced after the piston moves from the abnormal point, and the abnormal point is defined as an abnormal decrement point for identification, so that the different abnormal points can be distinguished conveniently.

Step S601: and defining a judgment interval with the width of a preset unit value along the forward direction of the coordinate axis of the point position at the abnormal increment point.

The positive direction of the point position coordinate axis is the moving direction of the piston, the unit value is the thickness value of the piston in the cylinder, and the judgment interval with the width as the unit value is defined at the abnormal increment point, so that the situation in the moving process of the piston can be known and analyzed.

Step S602: and judging whether or not there is one abnormal decrement point in the judgment interval.

The purpose of the judgment is to know whether an abnormal increment point can correspond to an abnormal decrement point so as to judge whether the abnormal increment point is caused by the defect of the cylinder side wall.

Step S6021: if there is one and only one abnormal decrement point in the determination section, a seal leakage signal is output and a region between the abnormal increment point and the abnormal decrement point is defined as a leakage region.

When one abnormal decrement point exists in the judgment interval and only one abnormal decrement point exists, the piston passes through one abnormal increment point in the moving process, the sealing condition is changed due to the fact that the piston passes through a defect of the side wall of the cylinder body, the abnormal decrement point exists in the judgment interval, the piston passes through the defect, the sealing influence caused by the defect is eliminated, and therefore a sealing leakage signal is output to mark the condition, and a worker can know the internal condition of the cylinder body; meanwhile, the area between the abnormal increment point and the abnormal decrement point is defined as a leakage area to be identified, so that the defect area in the cylinder body is marked, and subsequent workers can conveniently handle the defect area.

Step S6022: if the judgment interval is not available and only has one abnormal decrement point, a friction abnormal signal is output.

When the judgment interval is not available and only has one abnormal decrement point, the specific situation of the judgment interval cannot be analyzed, and at the moment, a friction abnormal signal is output to enable a worker to know the situation, so that the worker can add lubricating oil and the like in time to analyze again.

Referring to fig. 7, after the abnormal increment point and the abnormal decrement point are determined, the cylinder extension adjustment control method further includes:

step S700: and calculating the distance between each abnormal increment point and the end point of the point position coordinate axis to determine end point distance information, and calculating the distance between each abnormal decrement point and the starting point of the point position coordinate axis to determine starting point distance information.

The distance value corresponding to the end point distance information is the distance between the abnormal increment point and the end point in the point location coordinate axis, the distance value corresponding to the starting point distance information is the distance between the abnormal decrement point and the starting point in the point location coordinate axis, and both the abnormal decrement point and the starting point can be determined through corresponding coordinate numerical value calculation.

Step S701: and canceling the mark of the abnormal increment point corresponding to the end point distance information when the numerical value corresponding to the end point distance information is smaller than the unit value.

When the numerical value corresponding to the end point distance information is smaller than the unit value, the abnormal increment point is too close to the end point in the point position coordinate axis, and the abnormal decrement point matched with the abnormal increment point is possibly positioned outside the moving path of the piston, so that the condition of the abnormal increment point is inconvenient to analyze, the mark of the abnormal increment point is cancelled, and the interference in the subsequent analysis of the reason generated by the abnormal point is reduced.

Step S702: and canceling the mark of the abnormal decrement point corresponding to the starting point distance information when the numerical value corresponding to the starting point distance information is smaller than the unit value.

When the value corresponding to the starting point distance information is smaller than the unit value, the abnormal increment point is too close to the starting point in the point position coordinate axis, and the abnormal increment point matched with the abnormal interval quantity point is possibly positioned outside the moving path of the piston, so that the condition of the abnormal decrement point is inconvenient to analyze, the mark of the abnormal decrement point is cancelled, and the interference in the subsequent analysis of the reason generated by the abnormal point is reduced.
