[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Solenoid valves are widely used as basic automation components for controlling fluids. For example, the shifter in a vehicle uses a solenoid valve to control the switching and selection between various positions. As a special vehicle, operating machinery also uses a large number of solenoid valves. Taking a crane as an example, it can include telescopic arm solenoid valves, lifting and lowering solenoid valves, hoisting and lowering solenoid valves, slewing solenoid valves, and leg extension and retraction solenoid valves, etc. Each solenoid valve is controlled by an electrical system.

[0035] During the on-site operation of the operating machinery, the entire or part of the electrical system may not work properly due to bus failure, controller failure, line failure and other problems. At this time, all or part of the solenoid valves will not work, causing the operating machinery to malfunction. In the prior art, when encountering such a situation, service engineers or R&D personnel will carry debugging equipment to the site for investigation. After the troubleshooting and repair are completed, the solenoid valve that cannot work properly in the operating machinery can be controlled, or temporary wiring is used on site to control the solenoid valve that cannot work to force it to work.

[0036] In the prior art, when the solenoid valve fails to work due to the electrical system failing to work properly, although the manual intervention method can eventually solve the problem, it will increase the labor cost, and because the manual inspection and maintenance time is long, it may cause the operating machine to be in a load state or a dangerous state, which is prone to unpredictable dangers and reduces the safety of the operating machine. To this end, an embodiment of the present invention provides a solenoid valve control system.

[0037] Figure 1 A solenoid valve control system provided in an embodiment of the present invention includes: a control unit 1 and an output unit 2, wherein the control unit 1 includes a control circuit 11 and a signal adjustment unit 12;

[0038] The control circuit 11 is used to generate an initial control signal;

[0039] The signal adjustment unit 12 is used to obtain a user input instruction, and adjust the initial control signal based on the user input instruction to generate a target control signal of the solenoid valve 5 corresponding to the user input instruction;

[0040] The output unit 2 is used to be connected to the solenoid valve 5 and output the target control signal to the solenoid valve 5 .

[0041] Specifically, the solenoid valve control system provided in the embodiment of the present invention can realize forced control of the solenoid valve. The solenoid valve under forced control is usually a solenoid valve that cannot work due to the electrical system not working properly. According to the working principle, it can include a proportional solenoid valve, and can also include solenoid valves with other working principles. The proportional solenoid valve is a new type of hydraulic control device. On ordinary pressure valves, flow valves and directional valves, the original control part is replaced by a proportional electromagnet, and the pressure, flow or direction of the oil flow is continuously and proportionally controlled remotely according to the input electrical signal. Proportional solenoid valves generally have pressure compensation performance, and the output pressure and flow can be unaffected by load changes.

[0042] The solenoid valves subject to forced control can include telescopic arm solenoid valves, width raising and lowering solenoid valves, winch raising and lowering solenoid valves, rotary solenoid valves and outrigger telescopic solenoid valves according to their functions and installation positions.

[0043] The solenoid valve control system may include a control unit 1 and an output unit 2. The control unit 1 is connected to the output unit 2. The connection mode may be an electrical connection or a communication connection, which is not specifically limited here. The control unit 1 may generate a target control signal for the solenoid valve to be controlled, and the output unit 2 may output the target control signal generated by the control unit 1 to the corresponding solenoid valve.

[0044] The control unit 1 may include a control circuit 11 and a signal conditioning unit 12. The control circuit 11 may generate an initial control signal. The control circuit 11 may be a pulse width modulation (PWM) circuit, and the generated initial control signal may be a PWM signal. The initial control signal corresponds to the initial value of the control signal of the solenoid valve. Different solenoid valves may correspond to the same initial control signal or different initial control signals, which is not specifically limited here. Here, the initial control signal may be a control signal that controls the opening of the solenoid valve to reach the maximum.

[0045] The signal conditioning unit 12 can obtain a user input instruction, which can be used to represent an instruction corresponding to the state that the user needs the solenoid valve to reach. Here, the user may be a person who monitors the mandatory control of the solenoid valve, such as a service engineer or a research and development personnel. The state that the user needs the solenoid valve to reach may refer to the target opening that the solenoid valve needs to reach. For a proportional solenoid valve, the state that the user needs the solenoid valve to reach may be the target ratio that the proportional solenoid valve needs to reach.

[0046] In the control unit 1, a hardware input device for assisting in determining the user input instruction may be configured, and the user operates the hardware input device so that the hardware input device can obtain the user input. Thereafter, the signal conditioning unit 12 may convert the user input into a user input instruction. The hardware input device configured in the control unit 1 may be a control knob or a touch screen, which is not specifically limited here. Accordingly, the user's operation on the hardware input device may be twisting the control knob or directly inputting an operation on the touch screen.

[0047] After obtaining the user input instruction, the signal adjustment unit 12 can adjust the initial control signal generated by the control circuit 11 according to the user input instruction. Specifically, it can adjust the waveform of the initial control signal, such as adjusting the phase, amplitude and other parameters of the initial control signal, so that the target control signal of the solenoid valve corresponding to the user input instruction obtained after adjustment can be used to control the corresponding solenoid valve to meet user requirements, that is, to achieve the state of the solenoid valve required by the user.

[0048] The process of the signal adjustment unit 12 adjusting the initial control signal can be understood as a process of adjusting the control circuit through the signal adjustment unit 12 with the user input instruction as the target, so that the control circuit outputs the target control signal.

[0049] In an embodiment of the present invention, the signal adjustment unit 12 may be an adjustable resistor, such as a sliding rheostat, etc., or a potentiometer, and the resistance of the potentiometer may be changed as needed. In addition, the signal adjustment unit 12 may also be an adjustment switch circuit or an adjustment switch based on power or current, etc., which is not specifically limited here. The signal adjustment unit 12 may be connected in the control circuit to adjust the initial control signal generated by the control circuit 11 after obtaining the user input instruction.

[0050] When the signal adjustment unit is an adjustable resistor or a potentiometer, the signal adjustment unit 12 has an initial resistance value, that is, the initial resistance value of the adjustable resistor or the potentiometer. When the signal adjustment unit 12 does not obtain the user input instruction, the control circuit 11 is connected to an adjustable resistor with an initial resistance value, and an initial control signal is output to control the solenoid valve. When the signal adjustment unit is an adjustment switch circuit or an adjustment switch based on power or current, the signal adjustment unit 12 has an initial switch opening value, that is, the initial opening value of the switch in the adjustment switch circuit or the adjustment switch based on power or current. When the signal adjustment unit 12 does not obtain the user input instruction, the control circuit 11 is connected to a signal adjustment unit with an initial switch opening value, and an initial control signal is output to control the solenoid valve.

[0051] In particular, the PWM circuit may be provided with a microcontroller (MCU), in which a control circuit 11 and a signal conditioning unit 12 may be integrated, thereby making the microcontroller a controller capable of receiving user input instructions and outputting an initial control signal or a target control signal.

[0052] The output unit 2 is used to connect to the solenoid valve 5 corresponding to the user input command, that is, when the solenoid valve is forcibly controlled through the solenoid valve control system, the solenoid valve that needs to be forcibly controlled can be connected to the output unit 2. The target control signal obtained by the control unit 1 can be output to the solenoid valve 5 through the output unit 2, thereby realizing the forced control of the solenoid valve 5 so that the solenoid valve 5 works normally and ensures that the operating machine returns to the working state.

[0053] It can be understood that in the embodiment of the present invention, the number of signal adjustment units 12 in the solenoid valve control system can be one or more, each signal adjustment unit combined with the output unit corresponds to a control channel of the solenoid valve control system, and each control channel can be used to control a solenoid valve connected to the output unit. Therefore, the solenoid valve control system can force control of one or more solenoid valves at the same time.

[0054] The solenoid valve control system provided in the embodiment of the present invention generates an initial control signal through a control circuit in a control unit; adjusts the initial control signal through a user input instruction obtained by a signal adjustment unit to generate a target control signal of the solenoid valve corresponding to the user input instruction; and outputs the target control signal to the solenoid valve through an output unit. The solenoid valve control system realizes forced control of the corresponding solenoid valve through the target control signal, so that the solenoid valve can work normally, and no human intervention is required, which can greatly reduce labor costs. Moreover, it does not involve troubleshooting and maintenance, shortens the time for the solenoid valve and the operating machinery to resume normal operation, avoids the operating machinery being in a load state or a dangerous state, and improves the safety of the operating machinery.

[0055] On the basis of the above embodiment, in the solenoid valve control system provided in the embodiment of the present invention, the control unit further includes a hardware input device, and the hardware input device includes a proportional adjustment knob and / or a touch screen;

[0056] The hardware input device is used to receive the user input;

[0057] The signal adjustment unit is further configured to obtain the user input instruction in response to the user input.

[0058] Specifically, in an embodiment of the present invention, the hardware input device configured in the control unit can be either a proportional adjustment knob or a touch screen. The user can rotate the proportional adjustment knob so that the proportional adjustment knob receives the user input, which is the user's rotation operation on the proportional adjustment knob, including the rotation direction and rotation angle, etc.

[0059] In the signal adjustment unit, the solenoid valve states corresponding to the rotation angles under different rotation directions of the proportional adjustment knob may be stored, so the solenoid valve state corresponding to the user input may be determined through the corresponding relationship.

[0060] The user can also input the state that the solenoid valve needs to achieve on the touch screen, such as target opening, target ratio, etc.

[0061] Thereafter, the signal adjustment unit may respond to the user input and determine the user input instruction corresponding to the user input. If the signal adjustment unit is an adjustable resistor, the user input instruction obtained by the signal adjustment unit may be represented by the adjusted resistance value of the adjustable resistor.

[0062] In the embodiment of the present invention, by configuring hardware input devices such as a proportional adjustment knob and a touch screen in the control unit, user input and acquisition of user input instructions can be realized, which is convenient for introducing user needs and realizing personalized control of the solenoid valve.

[0063] On the basis of the above embodiment, in the solenoid valve control system provided in the embodiment of the present invention, the control unit further includes an on-off switch;

[0064] The on-off switch is connected between the signal conditioning unit and the output unit.

[0065] Specifically, in an embodiment of the present invention, the control unit further includes an on-off switch, which can be connected between the signal conditioning unit and the output unit, and is used to control the solenoid valve corresponding to the signal conditioning unit connected to the output unit. The on-off switch can be controlled by the user. When the output unit is not connected to the solenoid valve corresponding to the signal conditioning unit, the on-off switch is open. When the output unit is connected to the solenoid valve corresponding to the signal conditioning unit, the on-off switch is closed.

[0066] In the embodiment of the present invention, an on-off switch is introduced between the signal adjustment unit and the output unit, and the on-off state thereof is controlled by the user, thereby improving the safety of the solenoid valve control.

[0067] On the basis of the above embodiment, in the solenoid valve control system provided in the embodiment of the present invention, when the proportion adjustment knobs include multiple and the on-off switches include multiple, the proportion adjustment knobs correspond to the on-off switches one by one.

[0068] Specifically, in the embodiment of the present invention, the proportional adjustment knob may include one or more, each of which may be used to receive a user input, that is, each corresponds to a signal adjustment unit, so the number of on-off switches may also be one or more, and the on-off switches correspond to the signal adjustment units one by one. Furthermore, each control channel of the solenoid valve control system corresponds to a proportional adjustment knob, an on-off switch, and an output unit.

[0069] In an embodiment of the present invention, an on-off switch is introduced between each signal adjustment unit and the output unit. The user controls its open and closed state, so that the solenoid valve control system can independently control each solenoid valve when forcibly controlling multiple solenoid valves, thereby avoiding interference between the solenoid valves.

[0070] On the basis of the above embodiment, in the solenoid valve control system provided in the embodiment of the present invention, the output unit includes an output cable and a connector connected to one end of the output cable;

[0071] The other end of the output cable is connected to the control unit;

[0072] The connector is used to be connected to the solenoid valve.

[0073] Specifically, in the embodiment of the present invention, the output unit may include an output cable and a connector connected to one end of the output cable, the connector may match the solenoid valve and be used to connect to the solenoid valve so that the solenoid valve is connected to the solenoid valve control system. The other end of the output cable is connected to the control unit, specifically, it may be connected to the on-off switch in the control unit.

[0074] The length of the output cable can be set as needed, for example, it can be set to 3m, 5m, 10m, 50m, etc.

[0075] In the embodiment of the present invention, an output cable is introduced into the output unit, and the application distance of the solenoid valve control system can be unlimited by adjusting the length of the output cable.

[0076] On the basis of the above embodiment, in the solenoid valve control system provided in the embodiment of the present invention, when the proportion adjustment knobs include multiple and the output cables include multiple, the proportion adjustment knobs correspond to the output cables one by one.

[0077] Specifically, in the embodiment of the present invention, since the proportional adjustment knob may include one or more, the number of output cables may also be one or more, and the output cables correspond to the proportional adjustment knobs one to one. Furthermore, each control channel of the solenoid valve control system corresponds to a proportional adjustment knob, an on-off switch, an output cable, and a connector.

[0078] In the embodiment of the present invention, the proportional adjustment knob corresponds to the output cable one by one, so that the solenoid valve control system can independently control each solenoid valve when forcibly controlling multiple solenoid valves, thereby avoiding interference between the solenoid valves.

[0079] On the basis of the above-mentioned embodiment, in the solenoid valve control system provided in the embodiment of the present invention, the connector includes a two-core interface and / or a three-core interface.

[0080] Specifically, in the embodiment of the present invention, the connector may include a two-core interface and / or a three-core interface. For example, it may be a two-core interface AT06-2S-X150 or a three-core interface HM3250-03-0300 commonly used for solenoid valves, or both. This can increase the types of solenoid valves that can be controlled by the solenoid valve control system, making the application of the solenoid valve control system more extensive and more adaptable.

[0081] On the basis of the above embodiment, the solenoid valve control system provided in the embodiment of the present invention further includes: a power supply module, the power supply module is connected to the control unit;

[0082] The power supply module includes a power switch, a lithium battery unit and / or a power supply interface.

[0083] Specifically, in an embodiment of the present invention, the solenoid valve control system may further include a power supply module, which may be connected to the control unit to supply power to the entire solenoid valve control system. The power supply module may include a power switch, and the on and off state of the power switch may be controlled by a user. In addition, the power supply module may also include at least one of a lithium battery unit and a power supply interface. The power supply module may also include a protection circuit, which may have the functions of short circuit, overload and reverse connection protection to ensure the safety of the power supply module.

[0084] The lithium battery unit may include a lithium battery and a charging port, which can be connected to industrial electricity or household electricity through a charging cable to charge the lithium battery. The lithium battery unit allows the solenoid valve control system to work without the need for additional power supply equipment, and can be used in areas where it is inconvenient to access industrial electricity or household electricity, thereby improving the portability of the solenoid valve control system. The output voltage of the lithium battery can be 24V.

[0085] The power supply interface can be connected to the battery of the device where the solenoid valve is located through a wire, and the solenoid valve control system can be powered by the battery, which can also get rid of the solenoid valve control system's dependence on industrial electricity or household electricity when working. Here, the power supply interface can be connected from the battery when the lithium battery is out of power or a large current output is required on site.

[0086] In addition, the power supply interface can be directly connected to industrial electricity or household electricity through a wire, so that the solenoid valve control system is powered by industrial electricity or household electricity when working.

[0087] In the embodiment of the present invention, a power supply module is introduced into the solenoid valve control system, which can improve the portability of the solenoid valve control system on the basis of ensuring the normal operation of the solenoid valve control system.

[0088] On the basis of the above embodiment, the solenoid valve control system provided in the embodiment of the present invention further includes an outer protection box, which is used to encapsulate the solenoid valve control system. Accordingly, the proportional adjustment knob and the on-off switch can be arranged on the upper surface of the outer protection box, the charging port and the power supply interface can be arranged on the left side of the outer protection box, and the connector of the output unit can be arranged on the front surface of the outer protection box.

[0089] When in use, the solenoid valve control system is connected to electricity or uses its own lithium battery for power supply, closes the power supply switch, finds the solenoid valve to be controlled, connects the connector of the output unit to the corresponding solenoid valve, adjusts the proportional adjustment knob, closes the on-off switch, and then the corresponding solenoid valve can be forced to act, thereby controlling the normal operation of the equipment where the solenoid valve is located.

[0090] like Figure 2 As shown, the solenoid valve control system may include a power supply module 3, a control unit 1, an output unit 2 and an outer protection box 4, wherein the power supply module 3 includes a charging port 31, a power supply interface 32, a lithium battery 33 and a power switch 34.
