Description

Technical Field

[0001] The invention relates to the technical field of aerial electrostatic field monitoring, and in particular to a closed airborne electric field tester and an unmanned aerial vehicle. Background Art

[0002] Static electricity, as a common physical phenomenon, is caused by the unbalanced distribution of electric charge in matter. As we all know, the atoms that make up matter are composed of positively charged nuclei and negatively charged electrons. Under normal circumstances, the positive and negative charges in an object are equal and do not show electrical properties to the outside. However, under certain external forces (such as friction), the object gains or loses a certain number of electrons, making the positive and negative charges inside the object unequal, and the object will show electrical properties to the outside, that is, static electricity is generated. After the static electricity of an object accumulates, due to the different electric potentials of different objects, when the potential difference is large enough or two objects with unequal electric potentials come into contact, the charge is transferred through instantaneous current, which is discharge. For example, electric sparks and lightning on winter sweaters are common discharge phenomena.

[0003] Static electricity discharge may cause serious harmful effects in industry, such as explosions of gas or dust, and failure of solid-state electronic components (such as integrated circuits) (static electricity can directly cause permanent damage to electronic devices). However, the generation of static electricity is very simple and difficult to detect, and countless major accidents have occurred as a result.

[0004] In the field of aerial static electricity monitoring technology, aerial electric field testers can modulate the induced charge on the induction electrode through vibration or rotation, measure the electric field strength near the charged body, and invert the electrostatic voltage of the charged body, mainly including vibration capacitive electrostatic sensors, field grinding electrostatic sensors, etc. However, due to the need for sensor monitoring, existing aerial electric field testers generally expose the sensor sensitive chip to the outside, making it easy to be damaged or cause other safety hazards, such as being damaged in harsh environments such as dust, and generating electric sparks due to self-friction or collision with the outside world, causing safety hazards.

[0023] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0024] In order to solve the technical problem that the existing aerial electric field tester is prone to self-damage or potential safety hazard due to exposed sensor chips, the present invention discloses an airborne electric field tester and a drone.

[0025] One aspect of the present invention discloses an airborne electric field tester, which includes: a shell component and an internal component, the shell component is used to form a housing space and provide support for the airborne electric field tester; the shell component is also used to form the appearance structure of the airborne electric field tester of the present invention.

[0026] The internal components are arranged in the accommodation space formed by the shell component, and are used to provide the airborne electric field tester with monitoring of the airborne electrostatic field; the internal components include various functional elements that can realize the functions of the airborne electric field tester of the present invention. It should be noted that the accommodation space of the general shell component needs to be set as a closed space to achieve insulation and isolation between the internal components and the outside world.

[0027] Among them, Figure 1-Figure 2As shown, the shell assembly includes: a sensing electrode 110, which is used to sense the electrostatic field in the air to generate an electrostatic induction signal; the sensing electrode can be a plate-like structure, such as a circular or rectangular plate-like structure, with a certain extension area to achieve contact with a larger area of ​​the electrostatic field, so that the airborne electric field tester of the present invention has a more sensitive detection capability. In other words, the sensing area of ​​the airborne electric field tester is increased by the sensing electrode 110, and the electrostatic detection sensitivity and reliability of the airborne electric field tester are improved.

[0028] like Figure 1-Figure 2 As shown, the internal components include: an electric field sensitive element 210, which is connected to the sensing electrode 110. Specifically, the electric field sensitive element 210 is a sensor chip for sensing electrostatic field or AC electric field made by micro-nano processing technology, and is used to receive electrostatic induction signals to generate electrostatic monitoring signals. Therefore, the electric field sensitive element 210 of the present invention is arranged in the accommodation space of the shell component. Since the accommodation space is closed, the electric field sensitive element 210 is protected from damage caused by the external environment, so that the detection sensor chip of the airborne electric field tester of the present invention is better protected.

[0029] Therefore, the airborne electric field tester proposed in the present invention has an integrated structure, and obviously has structural characteristics such as small size and light weight, making it easier to mount on small aircraft, greatly reducing the threshold for airborne electrostatic field monitoring. In addition, compared with other existing airborne electric field testers, the airborne electric field tester proposed in the present invention has no exposed electric field sensitive element 210, and the sensing area of ​​the sensing electrode 110 is larger and can be further expanded, which fully guarantees the high-precision detection of the electric field sensitive element 210 and the high resolution of the detection data.

[0030] According to an embodiment of the present invention, wherein Figure 1-Figure 2 As shown, the housing assembly further includes: a housing 120, an isolating member 130 and a bottom shell 140. The housing 120 is a columnar three-dimensional structure with an opening at the bottom, which is disposed below the sensing electrode 110 and is spaced apart from the sensing electrode 110 by a certain isolating distance d. The upper surface of the housing 120 is spaced apart from the lower surface of the sensing electrode 110 by the isolating distance d.

The height of the isolating member 130 is equal to the above-mentioned isolation distance d, and is used to separate the sensing electrode 110 and the shell 120 and insulate each other. Specifically, the connection and fixation between the shell 120 and the isolating member 130 can be one of the connection methods such as screw fixing, welding, and bonding; in addition, the sensing electrode 110 is fixed on the isolating member 130, and the isolating member 130 protrudes from the upper surface of the shell 120, so that the sensing electrode 110 is exposed to the outside for sensing the electric field. Among them, the fixation between the sensing electrode 110 and the isolating member 130 can also be one of the connection methods such as screw fixing, welding, and bonding. The isolating member 130 is used to separate the sensing electrode 110 and the shell 120 carrying the internal components so that the two cannot directly contact.

[0032] According to an embodiment of the present invention, Figure 1-Figure 2 As shown, the bottom shell 140 is disposed below the housing 120, and a portion of its edge matches the lower opening of the housing 120, and is used to cooperate with the housing 120 to enclose the accommodating space 101.

Specifically, a notch matching the size of the protrusion 141 is provided on an edge of the lower opening of the shell 120, so that the protrusion 141 is just stuck on the notch, and the bottom shell 140 is a plate-like structure, and the edge of the bottom shell 140 except the protrusion 141 matches the edge of the lower opening of the shell 120 except the notch, so that a closed accommodation space is formed in the shell 120. In an embodiment of the present invention, a positioning hole 142 is provided on the protrusion 141. A plurality of positioning holes 142 may be provided, which are evenly or symmetrically distributed on the protrusion 141 to ensure that the airborne electric field tester is more stably fixed to the mounting portion of the drone, so as to ensure that the airborne static electricity tester is fixed to the drone. In addition, a limiting hole 143 may be provided on the protrusion 141 to further ensure that the airborne electric field tester is stably fixed to the drone.

[0033] It should be further explained that there may be at least two protrusions 141, and at least two protrusions 141 extend outwardly and symmetrically on the edges opposite to each other on the bottom shell 140, thereby enabling the airborne electric field tester of the present invention to have a more stable fixing effect when fixed on a drone.

[0034] In addition, in the embodiment of the present invention, the bottom shell 140 can be fixedly connected to the edge of the lower opening of the housing 120 by threaded connection, screw fixing, welding, etc., and the lower opening of the housing 120 is closed to form an accommodation space in the housing 120. It should be noted that, in the embodiment of the present invention, the bottom shell 140 is made of antistatic material, such as metal material.

[0035] According to an embodiment of the present invention, wherein Figure 1-Figure 2 As shown, the isolating member 130 is a columnar structure with a hollow space. The isolating member 130 cooperates with the lower surface of the sensing electrode 110 to form a hollow space 102 in the middle of the isolating member 130 and between the isolating member 130 and the housing 120. The isolating member 130 is made of insulating material, and the specific resistivity of the isolating member 130 is not less than 10 8 Therefore, the isolating member 130 has an excellent isolation effect, and insulates and isolates the sensing electrode 110 from the housing 120 .

[0036] The shell assembly also includes: an upper opening, which is arranged on the upper surface of the shell 120, and the edge of the upper opening is matched with the lower edge of the isolating member 130. In other words, the isolating member 130 can be an annular closed structure with a certain thickness, and its lower end opening matches the shape and size of the upper opening opened on the upper surface of the shell 120. In addition, the isolating member 130 cooperates with the sensing electrode 110, and the isolating member 130 closes the accommodating space 101 of the shell 120 from the upper end of the upper side of the shell 120 through the isolating member 130, and the lower opening of the shell 120 is closed by the bottom shell 140. At the same time, the upper opening of the shell 120 can connect the accommodating space 101 of the shell 120 and the hollow space 102 in the middle of the isolating member 130. In other words, the upper opening of the shell 120 is used to connect the hollow space 102 of the isolating member 130 and the accommodating space 101 of the shell assembly, such as Figure 1-Figure 2 shown.

[0037] According to an embodiment of the present invention, wherein Figure 2 As shown, the airborne electric field tester further includes: a connecting wire 300, one end of which is fixedly connected to the lower surface of the sensing electrode 110, the main body of the connecting wire 300 passes through the hollow space 102 of the isolating member 130 and the accommodating space 101 of the housing 120, and the other end of the connecting wire 300 is fixedly connected to the electric field sensitive element 210. It can be seen that the middle space 102 of the isolating member 130 can also facilitate the passing of the connecting wire 300. The connecting wire 300 passes through the middle space 102, electrically connects the sensing electrode 110 exposed to the electrostatic field and the electric field sensitive element 210 built into the accommodating space 101 of the housing 120, and can be used for data transmission or electrical signal transmission between the two.

[0038] In an embodiment of the present invention, the connecting wire 300 is a conductive material, such as a conductive metal or metal alloy material. The electric field sensitive element 210 is fixed in the accommodating space 101 of the housing 120, and is electrically connected to the sensing electrode 110 by the connecting wire 300 passing through the hollow space 102 of the isolating member 130. With this structure, the airborne electric field tester of the present invention realizes that the electric field sensitive element 210 is connected and conducted with the sensing electrode 110 through the connecting wire 300, and the electrostatic induction area is expanded with the help of the sensing electrode 110, while protecting the precious electric field sensitive element 210 from being damaged by the outside world. In addition, the structure also greatly reduces the influence of the outside world on the detection of the electric field sensitive element 210, making the detection process of the electric field sensitive element 210 more stable, and the detection data more real, accurate and effective.

[0039] According to an embodiment of the present invention, the materials used to prepare the sensing electrode 110, the housing 120, and the bottom housing 140 are antistatic materials to minimize the impact of the outside world on the detection effect of the airborne electric field tester of the present invention, for example, further reduce the detection hardness of the built-in electric field sensitive element 210, and protect the normal operation of the internal components. Specifically, the housing 120, the bottom housing 140, and the sensing electrode 110 can be made of metal materials to prevent the impact of static electricity from the outside.

[0040] According to an embodiment of the present invention, wherein Figure 2 As shown, the internal components include: a shielding cover 220, which is arranged on the electric field sensitive element 210, and the electric field sensitive element 210 is enclosed and covered, and is used for insulation shielding, reducing monitoring interference, so as to protect the electric field sensitive element and ensure the accuracy of the electrostatic monitoring signal. Specifically, the electric field sensitive element 210 is fixed in the accommodating space 101 of the shell 120, and is sealed and wrapped by the shielding cover 220 so that it is not in contact with the outside world, and is connected to the sensing electrode 110 through a connecting line 300 through the hollow space 102 of the shielding cover 220 and the isolation member 130. It should be noted that if the shielding cover 220 performs a sealing and insulation treatment on the electric field sensitive element 210, the shielding cover 220 can be made of metal material to reduce the influence of the peripheral circuit on the electric field sensitive element 210.

[0041] According to an embodiment of the present invention, wherein Figure 1-Figure 2 As shown, the housing 120 is the main structure of the airborne electric field tester of the present invention, and the housing 120 includes: a system positioning antenna 150, a wireless communication antenna 160, a power control button 170, a charging interface 180 and a wired communication interface 190.

[0047] According to an embodiment of the present invention, wherein Figure 2 As shown, the internal components also include: a first circuit board 230 and a second circuit board 240 , which together constitute the internal circuit (ie, the peripheral circuit) of the airborne electric field tester of the present invention, which are fixed in the accommodating space 101 of the shell 120 .

[0048] like Figure 2 As shown, the first circuit board 230 is arranged in the accommodation space 101 parallel to the bottom shell 140, and is used to provide a driving signal for the electric field sensitive element 210, and is also used to process the electrostatic monitoring signal to generate electrostatic monitoring data, wherein the electric field sensitive element 210 is arranged on the first circuit board. Specifically, the first circuit board 230 is provided with an analog signal processing circuit and / or a signal amplification processing circuit, and the circuit of the first circuit board 230 can be integrated with a temperature and humidity sensor, an atmospheric pressure measurement sensor, and an air quality sensor, etc. The circuit structure on the first circuit board 230 mainly acts on the electric field sensitive element 210, and can provide the necessary driving signal for the electric field sensitive element 210, and at the same time, the weak signal (i.e., the electrostatic detection signal) output by the electric field sensitive element 210 is subjected to AV conversion, amplification, filtering, and A / D acquisition, and finally converted into electrostatic monitoring data.

[0049] like Figure 2 As shown, the second circuit board 240 is arranged between the first circuit board 130 and the bottom shell 140 in parallel with the first circuit board 230, and the second circuit board 240 is connected to the first circuit board 230, for receiving electrostatic monitoring data and storing and transmitting, and is also used to process the positioning data of the airborne electric field tester (corresponding to being connected to the system positioning antenna 150).

[0052] In summary, the airborne electric field tester based on the built-in structure of the electric field sensitive element is mainly used for monitoring the electrostatic field in the air. Its small size and light weight (actual total weight does not exceed 300g) enable it to be suspended on a small unmanned aerial vehicle, greatly reducing the threshold for detecting the electrostatic field in the air. The airborne electric field tester of the present invention fixes the electric field sensitive element in the accommodating space of the shell through a closed structure, thereby avoiding the electric field sensitive element from being damaged by the external harsh environment.
