Description

Technical Field

[0001] The present invention belongs to the technical field of electrostatic discharge devices, and particularly relates to an electrostatic discharge device with measurement and emission functions, and also relates to a method for monitoring electrostatic current signals using this device. Background Art

[0002] When an aircraft is flying in the air, the collision between the particles in the air and the skin material will cause charge transfer, making the surface of the aircraft carry a certain polarity charge, while the particles carry the opposite polarity charge. In order to ensure the flight safety of the aircraft, electrostatic dischargers are installed at the trailing edge and tip parts of the aircraft structure. The electrostatic discharger undergoes corona discharge at a low voltage and releases the deposited charge on the aircraft surface in the form of a small current. To ensure the overall electrostatic discharge effect of the aircraft, a sufficient number of electrostatic dischargers need to be installed, and at the same time, a reasonable layout of the electrostatic dischargers is required. Standard SAE ARP 5672 stipulates the relevant parameters of the aircraft electrostatic environment and the theoretical calculation method for the installation quantity of electrostatic dischargers. However, this standard does not have detailed regulations on the layout method of electrostatic dischargers. Currently, there are many types of aircraft models, especially new aircraft. How to layout the installation positions of electrostatic dischargers and evaluate the rationality of the installation quantity of electrostatic dischargers is crucial for aircraft electrostatic protection design. However, the existing electrostatic dischargers are difficult to monitor the discharge current during the flight of the aircraft, and it is impossible to evaluate the rationality of the installation quantity and layout of electrostatic dischargers. Summary of the Invention

[0003] The purpose of the present invention is to provide an electrostatic discharge device with measurement and emission functions, which solves the problem that the existing electrostatic dischargers are difficult to monitor the discharge current during the flight of the aircraft.

[0004] Another purpose of the present invention is to provide a method for monitoring electrostatic current signals.

[0005] The technical solution adopted by the present invention is that an electrostatic discharge device with measurement and emission functions includes a base. One end of the base is fixedly connected with an electrostatic discharger. An insulating sleeve is sleeved on the outer wall of the electrostatic discharger. A microstrip patch antenna array is installed on the outer wall of the insulating sleeve. It also includes a receiving antenna and a receiver. The receiving antenna is signal-connected to the microstrip patch antenna array, and the receiving antenna is connected to the receiver through a wire.

[0006] The characteristics of the present invention also lie in that: The base includes a connecting head. A threaded hole is opened in the middle of one end of the connecting head. The electrostatic discharger is installed in the threaded hole. The other end of the connecting head is fixedly connected with a connecting plate. The connecting plate is provided with a first mounting hole and a second mounting hole.

[0007] The static electricity discharger includes a discharge rod. One end of the discharge rod is fixedly connected with a metal joint, and the other end of the metal joint is installed in a threaded hole. The outer wall of the metal joint is connected to the microstrip patch antenna array, and the other end of the discharge rod is fixedly connected with a discharge end.

[0008] The discharge rod has a triangular prism structure, and an insulating sleeve is sleeved on the outer side of the triangular prism structure.

[0009] The microstrip patch antenna array includes a high-frequency unit and a very high-frequency unit, and the high-frequency unit and the very high-frequency unit are arranged on different outer sides of the triangular prism structure.

[0010] An antenna cover is arranged outside the high-frequency unit and the very high-frequency unit.

[0011] The very high-frequency unit includes a first ground plane, the first ground plane is laid on the outer wall of the insulating sleeve, a first dielectric substrate is laid outside the first ground plane, the first ground plane and the first dielectric substrate are both laid along an outer side of the triangular prism structure, a plurality of very high-frequency radiation patches are evenly pasted on the outer side of the first dielectric substrate along an outer side of the triangular prism structure, and further includes a first feeding port, the first feeding port is respectively connected with the metal joint and the very high-frequency radiation patch close to the base, and further includes a first grounding port, the first grounding port is respectively connected with the discharge end and the very high-frequency radiation patch far from the base.

[0012] The high-frequency unit includes a second ground plane, the second ground plane is laid on the outer wall of the insulating sleeve, a second dielectric substrate is laid outside the second ground plane, the second ground plane and the second dielectric substrate are both laid along another outer side of the triangular prism structure, a plurality of high-frequency radiation patches are evenly pasted on the outer side of the second dielectric substrate along another outer side of the triangular prism structure, and further includes a second feeding port, the second feeding port is respectively connected with the metal joint and one end of the high-frequency radiation patch close to the base, and further includes a second grounding port, the second grounding port is respectively connected with the discharge end and one end of the high-frequency radiation patch far from the base.

[0013] Another technical solution adopted by the present invention is a static electricity current signal monitoring method, including: S1. The deposited static electricity reaches the discharge end through the base, forms a high-impedance path and accumulates gradually; S2. When the static voltage of the high-impedance path reaches the threshold voltage, corona discharge occurs at the discharge end to form a current signal; S3. The current signal forms a high-frequency electromagnetic field through excitation; S4. The high-frequency electromagnetic field forms resonance radiation between the first dielectric substrate and the very high-frequency radiation patch, and between the second dielectric substrate and the high-frequency radiation patch; S5. The resonance radiation radiates electromagnetic waves to the outside to emit a static electricity discharge current signal; S6. The receiving antenna receives the electrostatic discharge current signal and transmits it to the receiver, and the receiver monitors the electrostatic discharge current signal.

[0014] Another feature of this invention is that: The specific process of S3 is as follows: The current signal is excited through the first feeding port and the second feeding port, and high-frequency electromagnetic fields are formed respectively between the high-frequency radiation patch and the first ground plane, and between the very high-frequency radiation patch and the second ground plane.

The deposited static electricity reaches the discharge end through the base, forms a high-impedance path and accumulates gradually; S2. When the static voltage of the high-impedance path reaches the threshold voltage, the discharge end generates a corona discharge to form a current signal; S3. The current signal forms a high-frequency electromagnetic field through excitation; S4. The high-frequency electromagnetic field forms a resonant radiation between the first dielectric substrate and the high-frequency radiation patch, and between the second dielectric substrate and the very high-frequency radiation patch; S5. The resonant radiation radiates electromagnetic waves to the outside to emit an electrostatic discharge current signal; S6. The receiving antenna receives the electrostatic discharge current signal and transmits it to the receiver, and the receiver monitors the electrostatic discharge current signal.

10. The electrostatic current signal monitoring method according to claim 9, characterized in that The specific process of S3 is as follows: The current signal is excited through the first feeding port and the second feeding port to form a high-frequency electromagnetic field respectively between the high-frequency radiation patch and the first ground plane, and between the very high-frequency radiation patch and the second ground plane.
