DETAILED DESCRIPTION

[0049] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0050] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0051] See also Figures 1 to 5 The present invention provides a remote manual and automatic voltage regulation system, comprising a monitoring module 1, a main control module 2, a driving element 3, an executive element 4 and an early warning module 5, wherein the main control module 2 is connected to the monitoring module 1, and the executive element 4 is connected to the driving element 3, and is characterized in that:

[0052] It also includes an automatic control module 6 and a control adjustment module 7;

[0053] The automatic control module 6 is connected to the monitoring module 1, the main control module 2 and the early warning module 5; the control adjustment module 7 is connected to the main control module 2, the automatic control module 6, the monitoring module 1 and the driving element 3;

[0054] The monitoring module 1 is used to monitor and feedback the pressure data of the corresponding nodes in the pressure system;

[0055] The main control module 2 is used for manually inputting control instructions, and then outputting corresponding control signals according to the input control instructions;

[0058] The driving element 3 is used to convert the control signal into a form suitable for the operation of the actuator 4;

[0059] The actuator 4 is used to perform specific actions according to the driving signal to complete the corresponding voltage regulation operation;

[0060] The warning module 5 is used to output a warning and emergency stop signal when the voltage regulating system detects abnormal data.

[0061] For further information, see Figure 2 The main control module 2 includes an input unit 21, a display unit 22 and a start-stop unit 23, wherein the input unit 21 is connected to the control adjustment module 7; the display unit 22 is connected to the monitoring module 1; and the start-stop unit 23 is connected to the automatic control module 6;

[0063] The display unit 22 is used to display and feedback the node pressure data in real time;

[0064] The start-stop unit 23 is used to perform start-stop control on the automatic control module 6 .

[0065] In this embodiment, the monitoring module 1 is mainly monitored by multiple sensors, and then the monitored pressure data is transmitted to the main control module 2 and the automatic control module 6 respectively. The main control module 2 can directly display the real-time monitored pressure data through the display unit 22, and then the user manually inputs the adjustment data through the input unit 21, so that the operator can manually adjust the pressure regulating system. At the same time, the automatic control module 6 can autonomously regulate the pressure in the entire pressure regulating system through the real-time pressure data of each node fed back by the monitoring module 1 without manual operation. When regulating, the control adjustment module 7 can adjust the final output control signal according to the specific regulation content, so as to complete different operations on the driving element 3 and the actuator 4 according to different pressure regulation conditions.

[0066] Preferably, see Figure 6In this scheme, the wireless remote control system as shown in the figure can be used for operation. The wireless remote control system includes the automatic control module 6, and the wireless remote control system display unit is the display unit 22 in the automatic control module 6, and the wireless remote control system and other control elements can constitute the input unit 21 in the automatic control module 6, so that the operator can operate quickly and conveniently.

[0067] Preferably, see Figures 7 to 11 In this scheme, the driving element 3 and the actuator 4 can respectively adopt corresponding hydraulic pressure regulating systems, wherein the hydraulic pressure regulating system includes components such as the oil cylinder, oil pump, shut-off valve and hydraulic pressure regulating valve as shown in the figure, further streamlining the equipment. As for the main control module in the automatic control module 6 and the main control module 2, a single-chip microcomputer as shown in the figure can be adopted. By adopting a single-chip microcomputer as the main control element, the size of the entire control device can be reduced, thereby increasing the scope of use of the equipment.

[0068] For further information, see Figure 2 The self-control module 6 includes a control parameter adjustment unit 61, a control main unit 62 and an adjustment instruction judgment unit 63. The control parameter adjustment unit 61 is connected to the adjustment instruction judgment unit 63 and the control main unit 62; the adjustment instruction judgment unit 63 is connected to the control main unit 62; the control main unit 62 is connected to the control adjustment module 7;

[0069] The control parameter adjustment submodule is used to adjust and set the pressure control range;

[0070] The control main unit 62 sends a corresponding control signal according to the feedback corresponding node pressure data combined with the set pressure control range;

[0071] The adjustment instruction judgment unit 63 outputs an adjustment instruction or a non-adjustment instruction according to the monitoring data of the monitoring module 1 and a preset normal pressure range value.

[0072] For further information, see Figure 3 The warning module 5 includes a judgment instruction analysis unit 51, an acoustic and light warning unit 52 and an emergency stop instruction output unit 53. The judgment instruction analysis unit 51 is connected to the automatic control module 6; the acoustic and light warning unit 52 is connected to the judgment instruction analysis unit 51; the emergency stop instruction output unit 53 is connected to the automatic control module 6;

[0073] The judgment instruction analysis unit 51 continuously monitors and analyzes the output adjustment instructions and non-adjustment instructions;

[0074] The sound and light warning unit 52 completes the warning of abnormal conditions according to the analysis results of the judgment instruction analysis unit 51;

[0075] The emergency stop instruction output unit 53 outputs an emergency stop signal in an abnormal situation according to the analysis result of the judgment instruction analysis unit 51 .

[0076] In this embodiment, the adjustment instruction judgment unit 63 can compare the corresponding node pressure data monitored by the monitoring module 1 with the standard data range value preset by the control parameter adjustment unit 61. When the corresponding node pressure data monitored by the monitoring module 1 exceeds the preset standard data range, the adjustment instruction will be output to activate the control main unit 62 for control;

[0077] When the monitored corresponding node pressure data meets the preset standard data range, a non-adjustment instruction will be output to interrupt the control of the control main unit 62 or continue the state of the control main unit 62 not controlling. When the control main unit 62 is activated by the adjustment instruction, the control main unit 62 can output a control signal for lowering or increasing the pressure by comparing the pressure data actually monitored by the monitoring module 1;

[0078] The judgment instruction analysis unit 51 mainly analyzes the judgment result of the adjustment instruction judgment unit 63 in the automatic control module 6 in combination with the duration. When it is monitored that the adjustment instruction issued by the adjustment instruction judgment unit 63 exceeds the set time range, the judgment instruction analysis unit 51 can judge that the corresponding adjustment system has a fault or cannot perform pressure controllable adjustment, and then it will prompt through the sound and light warning unit 52. When the judgment instruction analysis unit 51 judges that the abnormality is detected, after a preset time, the entire adjustment system still has not completed the corresponding regulation, then the emergency stop instruction output unit 53 will issue an emergency stop instruction, and then the emergency stop program set in the automatic control module 6 will cooperate with the corresponding emergency components to perform corresponding emergency processing.

[0079] For further information, see Figure 4 The control adjustment module 7 includes an input instruction judgment unit 71, an adjustment instruction analysis submodule 72 and a control signal output unit 73. The input instruction judgment unit 71 is connected to the main control module 2 and the automatic control module 6, and the adjustment instruction analysis submodule 72 is connected to the monitoring module 1 and the input instruction judgment unit 71; the control signal output unit 73 is connected to the adjustment instruction analysis submodule 72 and the driving element 3;

[0080] The input instruction judgment unit 71 integrates and analyzes the signals output by the main control module 2 and the automatic control module 6 and selects the corresponding control signal for transmission;

[0081] The adjustment instruction analysis submodule 72 analyzes the transmitted control signal and outputs control signals of different levels;

[0082] The control signal output unit 73 transmits the received control signal of the corresponding level.

[0083] For further information, see Figure 5 The adjustment instruction analysis submodule 72 includes a calculation unit 721, a classification unit 722 and a level signal output unit 723, wherein the calculation unit 721 is connected to the input instruction judgment unit 71; the classification unit 722 is connected to the calculation unit 721; and the level signal output unit 723 is connected to the classification unit 722;

[0084] The calculation unit 721 performs PID analysis and calculation according to the input control signal combined with the pressure control range set in the automatic control module 6 and the actual pressure data monitored by the monitoring module 1;

[0085] The classification unit 722 outputs a corresponding level signal according to the analysis and calculation result of the closed-loop operation of the calculation unit 721;

[0086] The level signal output unit 723 outputs a control signal of a corresponding level according to the received level signal.

[0087] When the present embodiment is in use, the input instruction judgment unit 71 is mainly used to select the control signals sent by the automatic control module 6 and the main control module 2. When the user sends a control signal through only one of the automatic control module 6 and the main control module 2, the input instruction judgment unit 71 will output the sent control signal. When the user simultaneously inputs a signal through the main control module 2 during the autonomous control process of the automatic control module 6, the input instruction judgment unit 71 will give priority to the control signal sent by the main control module 2 for transmission.

[0088] Under normal circumstances, when the user uses the main control module 2 for control, the start-stop unit 23 provided in the main control module 2 can be used in advance to control the automatic control module 6 to stop working, thereby ensuring the unity of the output control signal. However, when it is necessary to use a control system to control multiple groups of the drive elements 3 and the actuators 4, since each group of the drive elements 3 and the actuators 4 requires a separate control program, when the user selects a control program of a specified group to input instructions through the main control module 2, under normal circumstances, the control program of the specified group in the automatic control module 6 needs to be stopped in advance in order to smoothly input the control signal through the main control module 2, which makes the entire processing system and operation more troublesome. Therefore, by using the input instruction judgment unit 71, the control signal input by the main control module 2 can be transmitted and executed first;

[0089] It should be noted that the control signal types output by the main control module 2 and the automatic control module 6 in this solution can be understood as pressure down-regulation control instructions or pressure up-regulation control instructions, and the calculation unit 721 calculates the control difference through the actual data monitored by the monitoring module 1 combined with the preset control range value. For example, if the preset pressure range is "80" and the actual pressure detected by the monitoring module 1 is "100", the calculation unit 721 will calculate the absolute value of the difference between the actual pressure value "100" and the preset pressure value "80", and then use the calculated absolute value of the control difference to determine the level signal in conjunction with the classification unit 722;

[0090] The classification unit 722 can be set by the user according to actual conditions. For example, according to the absolute value of the difference in regulation, each "20" is a group, the first group is "1-10", the second group is "11-20", and so on. In the above case, after the actual pressure value "100" is subtracted from the preset pressure value "80", the difference "20" obtained will be classified into the difference through the classification unit 722. After that, the level signal output unit 723 can output the specified level control signal according to the preset multi-level control signal to complete the control slope signal output of the corresponding level. For different slope levels in the level signal output unit 723, The control signal is mainly an instruction for controlling specific parameters of the drive element 3. For example, when the user finally adopts the rotation of the motor to control the opening or closing of the valve, the control of the corresponding motor speed can be divided into corresponding levels according to the actual situation. That is, the faster the motor speed, the faster the overall regulation efficiency. When a large difference adjustment is required, the motor will be controlled to rotate faster through the output of the corresponding level control instruction. As for the control parameters of specific data, the user can divide and set them according to the actual situation, so as to adapt different control signals for control according to the actual regulation situation, so as to ensure the rapid and stable control efficiency of the entire voltage regulation system.

[0091] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
