[0027] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] Example

[0029] This embodiment provides a detection device for arc discharge during the operation of an ion wind rod, referring to Figure 1 and Figure 2 , including: a high-voltage discharge module 1, a discharge signal sensing module 2, an arcing signal detection module 3, a high-voltage output module 4 and a control module 5.

[0030] The high-voltage discharge module 1 is mainly composed of an ion wind rod, which is the core component of the entire device and is used to eliminate static electricity through high-voltage discharge. When the ion wind rod is working, the ion needle inside it will generate a high-voltage electric field, thereby ionizing the surrounding air and eliminating static electricity.

[0031] However, long-term operation and environmental factors may cause the ion needle inside the ion wind rod to become dirty or the material to age, which may lead to arc discharge or short circuit to the ground. This arc discharge may not only damage the ion wind rod, but also cause serious accidents such as fire.

[0032] In order to monitor the arc discharge state of the ion wind rod in real time, the present embodiment provides a discharge signal sensing module 2. The module mainly includes sensing sensors, which are installed on the high-voltage line at the end of the remote high-voltage power supply.

[0033] When the ion wind rod arcs, the induction sensor can quickly capture the weak signal generated by the discharge, which is then transmitted to the arc signal detection module 3 for further processing.

[0034] The arc signal detection module 3 is responsible for accurately analyzing and processing the received arc signal. The module includes submodules such as a signal primary amplification module, a high-voltage signal coupling module, a signal conversion module and a difference amplification module which are connected in series in sequence.

[0035] The signal primary amplification module first amplifies the received weak arcing signal to achieve the signal strength required for subsequent processing. The high-voltage signal coupling module is responsible for coupling the amplified signal with the high-voltage power supply for subsequent signal processing.

[0036] The signal conversion module converts the coupled signal into a format suitable for digital processing and then passes it to the differential amplifier module, which further amplifies and processes the signal to more accurately determine the arc discharge state.

[0037] The high-voltage output module 4 is responsible for controlling and generating high-voltage voltage to provide a stable power supply for the ion wind rod. The module includes a transformer switch signal module and a complementary adjustable PWM signal module connected in parallel to the output end of the MCU. The output end of the transformer switch signal module is connected in parallel with a positive high-voltage transformer and a negative high-voltage transformer. The output ends of the positive high-voltage transformer and the negative high-voltage transformer are both connected to the voltage doubler rectifier module. The output end of the voltage doubler rectifier module is connected in series with the induction sensor and the ion wind rod through a high-voltage line.

[0038] The transformer switch signal module and the complementary adjustable PWM signal module work together to generate a stable control signal to drive the positive high-voltage transformer and the negative high-voltage transformer to generate a high-voltage power supply. The voltage doubler rectifier module rectifies and doubles the high-voltage power supply to meet the working requirements of the ion wind rod.

[0039] Preferably, in a detection device for arc discharge occurring during the operation of an ion wind rod in this embodiment, the high-voltage output module 4 also includes a pulse AC power supply connected to the output end of the transformer input power controller, the positive pulse output end of the pulse AC power supply is connected to the input end of the positive high-voltage transformer, and the negative pulse output end of the pulse AC power supply is connected to the input end of the negative high-voltage transformer.

[0040] The pulse AC power supply provides a stable input power supply for the transformer. By accurately controlling the output of the pulse AC power supply, accurate regulation and control of the high voltage output can be achieved.

[0041] The control module 5 is the core control part of the whole device, including components such as ADC module, MCU and transformer input power controller.

[0042] The ADC module is connected in series with the MCU, the MCU is connected in series with the transformer input power controller, and an arc-pulling shutdown power supply is also connected between the MCU and the transformer input power controller, and the input end of the pulse AC power supply is also connected to the output end of the complementary adjustable PWM signal module.

[0043] The ADC module, analog-to-digital converter, is a bridge between analog systems and digital systems. It can convert external analog signals into digital signals so that digital systems can process these signals.

[0044] MCU, or microcontroller, is the core of embedded systems. It consists of components such as microprocessor core, memory and peripheral interface. The microprocessor core is responsible for executing instruction sets and processing data, the memory is used to store program instructions and data, and the peripheral interface connects the MCU with other external devices.

[0045] In this embodiment, the ADC module is responsible for converting the analog signal output by the arc signal detection module 3 into a digital signal for processing by the MCU. The MCU receives the digital signal converted by the ADC module and makes a comprehensive judgment with other input signals. When it is determined that the ion wind rod has an arc discharge, the MCU will immediately issue a control instruction to turn off the output of the high-voltage output module 4, thereby avoiding further damage and safety accidents.

[0046] The transformer input power controller is responsible for controlling the input and output of the pulse AC power supply to ensure the stable operation of the high voltage output module 4. At the same time, it also receives the control instructions of the MCU and adjusts the output state of the pulse AC power supply according to the instructions.

[0047] In summary, the detection device for arc discharge during the operation of the ion wind rod of this embodiment monitors the arc discharge state of the ion wind rod in real time, promptly detects and shuts down the high voltage output, thereby effectively ensuring the static elimination performance and use safety of the ion wind rod. At the same time, the device also has the advantages of simple structure, convenient operation, high reliability, etc., and is suitable for the static elimination needs of various industrial sites. In the specific implementation process, its circuit connection schematic diagram refers to Figure 3 .

[0048] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
