[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to 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 the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0045] Embodiment 1

[0046] Please refer to Figure 1 The present application is a steel structure single-leaf hydraulic lifting camouflage door and a hydraulic control system thereof, which comprises:

[0047] The online monitoring module obtains the opening and closing parameters of the camouflage door connected to the hydraulic output end;

[0048] The opening and closing parameters include the real-time angular velocity of the camouflage door.

[0049] In some embodiments, when the steel structure single-leaf hydraulic lifting camouflage door is started and closed, the angular velocity of the camouflage door within the starting and closing time is obtained, which is marked as the real-time angular velocity Wm of the camouflage door.

[0050] The online analysis module analyzes the node signals of the camouflage door during starting and closing based on the opening and closing parameters, and obtains the angular velocity deviation data corresponding to each node signal.

[0051] The node signals include node deviation unqualified signals or node deviation qualified signals.

[0052] In some embodiments, the real-time angular velocity of the camouflage door obtained by the online monitoring module is obtained, and a preset opening and closing model of the camouflage door is obtained. According to the preset opening and closing model of the camouflage door, the key nodes and the opening and closing parameters corresponding to the key nodes are determined.

[0053] The determination process is as follows: taking the starting and closing time as the X-axis and the real-time angular velocity of the camouflage door as the Y-axis, a two-dimensional coordinate system is constructed, the preset real-time angular velocity of the camouflage door corresponding to the preset starting and closing time is substituted into the two-dimensional coordinate system, and a preset real-time angular velocity curve is drawn.

[0054] The initial time of starting and closing, the intermediate time of starting and closing, the maximum angular velocity time of starting and closing, the end time of starting and closing, and the real-time angular velocity corresponding to each time are extracted, which are respectively marked as the opening and closing initial time, the opening and closing intermediate time, the opening and closing maximum time, the opening and closing end time, and the opening and closing initial angular velocity, the opening and closing intermediate angular velocity, the opening and closing maximum angular velocity, and the opening and closing end angular velocity.

[0055] The real-time angular velocity of the camouflage door corresponding to the opening and closing initial time, the opening and closing middle time, the starting maximum time and the opening and closing final time is obtained, and the angular velocity difference values of the opening and closing initial time, the opening and closing middle time, the starting maximum time and the opening and closing final time are obtained by difference calculation, respectively.

[0056] The angular velocity difference values of the opening and closing initial time, the opening and closing middle time, the starting maximum time and the opening and closing final time are compared with the corresponding angular velocity difference threshold values, respectively.

[0057] If it is greater than or equal to, it means that the angular velocity of the corresponding key node has a large deviation from the preset angular velocity, and a node deviation unqualified signal is generated.

[0058] If it is less than, it means that the angular velocity of the corresponding key node has a small deviation from the preset angular velocity, and a node deviation qualified signal is generated.

[0059] For example: the angular velocity difference value of the opening and closing initial time is compared with the angular velocity difference threshold value of the opening and closing initial time.

[0060] If the angular velocity difference value of the opening and closing initial time is greater than or equal to the angular velocity difference threshold value of the opening and closing initial time, it means that the angular velocity of the corresponding key node has a large deviation from the preset angular velocity, and a node deviation unqualified signal of the opening and closing initial time is generated.

[0061] If the angular velocity difference value of the opening and closing initial time is less than the angular velocity difference threshold value of the opening and closing initial time, it means that the angular velocity of the corresponding key node has a small deviation from the preset angular velocity, and a node deviation qualified signal of the opening and closing initial time is generated.

[0062] The analysis and evaluation module: obtains the angular velocity deviation data corresponding to each node signal, determines the opening and closing operation instability total value, and compares the opening and closing operation instability total value with the opening and closing operation instability total threshold value to generate a camouflage door opening and closing stability signal.

[0063] The camouflage door opening and closing stability signal includes a camouflage door hydraulic control stability signal or a camouflage door hydraulic control instability signal.

[0064] In some embodiments, the angular velocity difference value of all node deviation unqualified signals is obtained, which is marked as WCi, wherein i represents the label of the node deviation unqualified signal. In order to facilitate data processing, the opening and closing initial time, the opening and closing middle time, the starting maximum time and the opening and closing final time can be labeled in order, which are 1, 2, 3 and 4, respectively.

[0065] The opening and closing instability value ZWbi of each node is calculated by the formula

[0066] ​Wherein, the time influence factor TX is obtained by:

[0067] The time node deviating from the unqualified signal is obtained, marked as Ts, and the time influence factor TX is calculated by formula , wherein Tk represents the initial time of starting closing, and Tj represents the end time of starting closing;

[0068] When the steel structure single-sash hydraulic lifting camouflage door is started and closed, the opening and closing instability values ZWbi of all nodes deviating from the unqualified signal are summed and calculated to obtain the total instability value of opening and closing operation;

[0069] The total instability value of opening and closing operation is compared with the total instability threshold value of opening and closing operation;

[0070] If the total instability value of opening and closing operation is greater than or equal to the total instability threshold value of opening and closing operation, a camouflage door hydraulic control stable signal is generated;

[0071] If the total instability value of opening and closing operation is less than the total instability threshold value of opening and closing operation, a camouflage door hydraulic control unstable signal is generated;

[0072] It should be noted that the camouflage door hydraulic control stable signal indicates that when the hydraulic control system controls the steel structure single-sash hydraulic lifting camouflage door to start and close, the running change of the camouflage door deviates from the normal condition to a lower extent, and the normal work of the camouflage door can be completed.

[0073] The camouflage door hydraulic control unstable signal indicates that when the hydraulic control system controls the steel structure single-sash hydraulic lifting camouflage door to start and close, the running change of the camouflage door deviates from the normal condition to a higher extent, which will have a certain impact on the normal work of the camouflage door.

[0074] The technical scheme of the embodiment of the present application: an online monitoring module obtains the opening and closing parameters of the camouflage door connected to the hydraulic output end;An online analysis module analyzes each node signal of the camouflage door when starting and closing based on the opening and closing parameters;An analysis and evaluation module obtains the angular velocity deviation data corresponding to each node signal, determines the total instability value of opening and closing operation, and compares the total instability value of opening and closing operation with the total instability threshold value of opening and closing operation to generate a camouflage door opening and closing stability signal;The present application realizes accurate evaluation of the running state of the camouflage door through online deviation analysis of the running state of the camouflage door by the hydraulic control system, and analyzes the stability of the work of the hydraulic system, thereby ensuring the reasonable stability of the work of the camouflage door hydraulic control system.

[0077] The hydraulic correction module adjusts the pressure setting value of the pressure control valve based on the camouflage door hydraulic control instability signal.

[0078] In some embodiments, when the camouflage door hydraulic control instability signal is obtained, the current pressure setting value of the pressure control valve is acquired, the current pressure setting value of the pressure control valve is multiplied by the regulation proportion coefficient to obtain the pressure target adjustment value of the pressure control valve.

[0079] The regulation proportion coefficient is obtained by the following process:

[0080] The on-off operation instability total value and the on-off operation instability total threshold value are obtained, the on-off operation instability total value is subtracted from the on-off operation instability total threshold value to obtain the on-off operation instability total difference value, and the on-off operation instability total difference value is divided by the on-off operation instability total threshold value to obtain the regulation proportion coefficient.

[0081] When the pressure target adjustment value of the pressure control valve is calculated, it is sent to the PLC of the camouflage door hydraulic control system, so that the camouflage door works according to the pressure target adjustment value in the next work, and the problem that the running change of the camouflage door deviates from the normal situation to a higher degree is compensated by the correction of the pressure target adjustment value, the running stability of the hydraulic control system is ensured, and the camouflage door is more stable during operation.

[0082] The technical scheme of the embodiment of the present application is: a hydraulic correction system adjusts the pressure setting value of the pressure control valve based on the camouflage door hydraulic control instability signal; the present application compensates for the problem that the running change of the camouflage door deviates from the normal situation to a higher degree by the correction of the pressure target adjustment value, ensures the running stability of the hydraulic control system, and makes the camouflage door more stable during operation.

[0083] Embodiment 3

[0086] The hydraulic cylinder 3 is installed on the ground at one end, and is connected to the middle part of the camouflage door body 1 at the other end.

[0087] The working principle of the present application is: the online monitoring module: obtains the opening and closing parameters of the camouflage door connected to the hydraulic output end; the online analysis module: based on the opening and closing parameters, analyzes the node signals of the camouflage door when starting and closing; the analysis and evaluation module: obtains the angular velocity deviation data corresponding to each node signal, determines the total value of unstable opening and closing operation, and then compares the total value of unstable opening and closing operation with the total threshold value of unstable opening and closing operation, to generate a signal indicating whether the opening and closing of the camouflage door is stable;

[0088] The hydraulic correction module adjusts the pressure set value of the pressure control valve based on the unstable signal of the hydraulic control of the camouflage door. The present application compensates for the problem that the operation of the camouflage door deviates from the normal condition to a high degree through the correction of the pressure target adjustment value, ensures the operation stability of the hydraulic control system, and thus makes the operation of the camouflage door more stable.
