Solenoid valves are widely used as the basic elements for controlling the automation of fluids. For example, shifters in vehicles use solenoid valves to control the switching and selection between various positions. Work machines are used as a special type of vehicle, in which a large number of solenoid valves are also used. Taking the crane as an example, the crane can comprise a telescopic arm electromagnetic valve, a breadth rising and breadth falling electromagnetic valve, a hoisting rising and breadth falling electromagnetic valve, a rotary electromagnetic valve, a supporting leg telescopic electromagnetic valve and the like, and all the electromagnetic valves are controlled by an electrical system.

Therefore, the embodiment of the invention provides a solenoid valve control system.
Fig. 1 is a solenoid valve control system provided in an embodiment of the present invention, including: the device comprises a control unit 1 and an output unit 2, wherein the control unit 1 comprises a control circuit 11 and a signal adjusting unit 12;
the control circuit 11 is used for generating an initial control signal;

the output unit 2 is configured to be connected to the solenoid valve 3 and output the target control signal to the solenoid valve 3.
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 that is forced to be controlled is usually a solenoid valve that cannot work due to the failure of the electrical system, and may include a proportional solenoid valve according to the working principle, and may also include a solenoid valve according to another working principle. The proportional electromagnetic valve is a new type of hydraulic control device. On the common pressure valve, flow valve and direction valve, the proportional electromagnet is used to replace the original control part, and the pressure, flow or direction of oil flow is controlled remotely according to the input electric signal. Proportional solenoid valves generally have pressure compensation capability, and output pressure and flow can be unaffected by load changes.
The solenoid valves which are forcibly controlled can comprise a telescopic arm solenoid valve, a breadth rising and breadth falling solenoid valve, a winch rising and descending solenoid valve, a rotary solenoid valve, a landing leg telescopic solenoid valve and the like according to functions, installation positions and the like.
The electromagnetic valve control system may include a control unit 1 and an output unit 2, where the control unit 1 is connected to the output unit 2, and the connection mode may be an electrical connection or a communication connection, and is not limited specifically here.

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 is an initial value of a control signal corresponding to the solenoid valve, and different solenoid valves may correspond to the same initial control signal or different initial control signals, which is not specifically limited herein. Here, the initial control signal may be a control signal that controls the opening degree of the solenoid valve to be maximum.
The signal conditioning unit 12 may obtain a user input command, which may be used to represent a command corresponding to a state that a user needs to achieve the solenoid valve. Here, the user may be a person who monitors forced control of the solenoid valve, such as a service engineer or a developer. The state that the user needs the electromagnetic valve to reach may refer to a target opening degree that the electromagnetic valve needs to reach. For a proportional solenoid valve, the state that the user needs the solenoid valve to reach may be the target proportion that the proportional solenoid valve needs to reach.
In the control unit 1, a hardware input device for assisting determination of a user input instruction may be provided, and a user operates the hardware input device so that the hardware input device can acquire a user input. Thereafter, the signal conditioning unit 12 may convert the user input into a user input instruction.

In addition, the signal conditioning unit 12 may be a regulation switch circuit, a regulation switch based on power or current, or the like, and is not limited in particular here. The signal adjusting unit 12 may be connected in the control circuit to adjust the control circuit 11 to generate the initial control signal after acquiring the user input instruction.
When the signal adjusting unit is an adjustable resistor or a potentiometer, the signal adjusting unit 12 has an initial resistance value, that is, the initial resistance value of the resistor of the adjustable resistor or the potentiometer, and when the signal adjusting unit 12 does not obtain an instruction input by a user, the adjustable resistor with the initial resistance value is connected to the control circuit 11, and an initial control signal is output to control the solenoid valve. When the signal adjusting unit is an adjusting switch circuit or an adjusting switch based on power or current, the signal adjusting unit 12 has an initial switch opening value, that is, an initial opening value of a switch in the adjusting switch circuit or an adjusting switch based on power or current, and when the signal adjusting unit 12 does not obtain an instruction input by a user, the signal adjusting unit with the initial switch opening value is connected to the control circuit 11, and an initial control signal is output to control the electromagnetic valve.
In particular, the PWM circuit may have a Microcontroller (MCU), and the control circuit 11 and the signal conditioning Unit 12 may be integrated in the MCU, so that the MCU becomes a Controller capable of receiving a user input command and outputting an initial control signal or a target control signal.
The output unit 2 is used for being connected with the electromagnetic valve 3 corresponding to the instruction input by the user, namely when the electromagnetic valve is forcibly controlled by the electromagnetic valve control system, the electromagnetic valve needing to be forcibly controlled can be connected with the output unit 2. The target control signal obtained by the control unit 1 can be output to the electromagnetic valve 3 through the output unit 2, so that the electromagnetic valve 3 is forcibly controlled to normally work, and the working state of the working machine is ensured to be recovered.
It is understood that in the embodiment of the present invention, the number of the signal conditioning units 12 in the solenoid valve control system may be one or more, each signal conditioning unit in combination with the output unit corresponds to one control channel of the solenoid valve control system, and each control channel may be used to control one solenoid valve connected to the output unit, so that the solenoid valve control system may perform forced control on one or more solenoid valves at the same time.
