With the increasing level of industrial automation, the application areas of solenoid valves are constantly expanding, from simple fluid control to complex system integration, making the performance and reliability of solenoid valves particularly important.

[0003] Although solenoid valves are widely used in industrial control, the existing technology for condition monitoring and fault detection is relatively backward, mainly relying on manual inspection, which cannot achieve real-time monitoring and intelligent management. Utility Model Content

[0004] The technical solution to be solved by this utility model is to provide a solenoid valve status monitoring device, which can accurately and quickly detect the status of the solenoid valve.

[0005] The technical solution adopted in this utility model is: a solenoid valve status monitoring device, which includes a solenoid valve with an indicator light, and includes a processor, a power module, a control switch, a current and voltage detection module, an industrial camera, a button module, and an alarm module. The power module, control switch, current and voltage detection module, industrial camera, button module, and alarm module are all electrically connected to the processor. The power module is electrically connected to the solenoid valve after passing through the current and voltage detection module and the control switch. The power module is used for power supply; The current and voltage detection module is used to detect the current and voltage of the solenoid valve. Control switch, used to control the on / off state of the solenoid valve; Industrial camera used to photograph the status of indicator lights on solenoid valves; Button module for parameter adjustment and control; The alarm module issues an alarm signal when an anomaly is detected. The processor receives information from the current and voltage detection module and the industrial camera, then determines whether the solenoid valve is malfunctioning. When the solenoid valve is malfunctioning, it controls the alarm module to issue an alarm signal.

[0006] Preferably, the processor includes a first processor and a second processor. The power module, control switch, current and voltage detection module, button module and alarm module are all electrically connected to the first processor. The industrial camera is electrically connected to the second processor, and the first processor and the second processor are electrically connected.

[0007] Preferably, the first processor is a microcontroller of model STM32F103C8T6, and the second processor is a computer.

[0008] Preferably, the power supply module includes a regulated power supply for outputting a 24V voltage, a first step-down circuit for stepping down the 24V voltage to a 5V voltage, and a second step-down circuit for stepping down the 5V voltage to a 3.3V voltage. The regulated power supply is electrically connected to the current and voltage detection module through the first step-down circuit, and the regulated power supply is electrically connected to the first processor through the first step-down circuit and the second step-down circuit.

[0009] Preferably, the current and voltage detection module includes a Hall current sensor of model ACS712ELCTR-05B.

[0010] Preferably, the alarm module includes a buzzer and a warning light.

[0011] Compared with the prior art, the present invention has the following advantages: by using a current and voltage detection module to detect whether the current and voltage of the solenoid valve are abnormal, and then by using an industrial camera to detect whether the opening and closing frequency of the solenoid valve is abnormal, the status of the solenoid valve can be detected quickly and accurately.

[0012] Two processors are used: one processor is responsible for controlling the working status of the solenoid valve and monitoring its voltage and current operation, while the other processor is responsible for processing the images captured by the industrial camera to determine whether the opening and closing frequency of the solenoid valve is abnormal. This results in a better overall detection effect.

[0013] Using this type of power module can effectively power all modules.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0018] A solenoid valve status monitoring device includes a solenoid valve, a first processor, a second processor, a current and voltage detection module, a power supply module, a control switch, an industrial camera, a button module, and an alarm module. The current and voltage detection module, power supply module, control switch, button module, and alarm module are all electrically connected to the first processor. The industrial camera is electrically connected to the second processor. The first processor and the second processor are also electrically connected. Solenoid valves are commercially available solenoid valves with indicator lights to indicate their status. The power module includes a 24V regulated power supply, a first step-down circuit, and a second step-down circuit. The first step-down circuit is used to reduce the 24V voltage to 5V, and the second step-down circuit is used to reduce the 5V voltage to 3.3V. After the voltage is reduced to 5V, it supplies power to the current and voltage detection module, and after the voltage is reduced to 3.3V, it supplies power to the first processor. The current and voltage detection module includes a Hall current sensor (model ACS712ELCTR-05B) and a voltage divider resistor. The Hall current sensor detects the current, and the voltage divider resistor is used to detect the voltage using a resistor voltage divider method. Control switch, used to control the on / off state of the solenoid valve; The button module is equipped with buttons for parameter adjustment and control; The alarm module includes a buzzer and a warning light, which will sound an alarm when an abnormality is detected in the solenoid valve; The first processor is a microcontroller of model STM32F103C8T6, which is used to receive signals from the current and voltage detection module and the second processor, and then control the control switch and alarm module to work. It can also adjust parameters and directly control the control switch and alarm module through the button module. When the current and voltage detection module detects an abnormality in the current or voltage of the solenoid valve, it will control the solenoid valve to disconnect and then control the alarm module to sound an alarm.

[0019] The industrial camera, specifically a high-speed industrial camera, is mainly used to determine whether the on / off frequency of the solenoid valve is abnormal by photographing the indicator lights on the solenoid valve. Since high-speed industrial cameras are conventional products in the existing technology, and identifying the on / off frequency of the solenoid valve by taking pictures of the indicator lights on the solenoid valve with a high-speed industrial camera is also a conventional technology in the existing technology, it is not elaborated in detail in this embodiment. The second processor, a computer, is mainly used to receive photos of the indicator lights of the solenoid valves from industrial cameras. It then determines whether the on / off frequency of the solenoid valves is abnormal based on these photos. Since this determination is simple and can be easily done with existing image recognition software, it is not elaborated here. If an abnormal on / off frequency of the solenoid valves is detected, it will send a signal to the first processor, which will then control the solenoid valves to disconnect and trigger the alarm module to sound an alarm.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0021] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
