Problems solved by technology

However, its structure is relatively complex, and generally speaking, it can only detect one-dimensional electric fields, which has certain limitations in practical applications. When it is necessary to detect multi-dimensional electric fields, such as two-dimensional or three-dimensional electric fields, multiple sensors must be used separately Detecting and synthesizing the electric field signals of various dimensions will increase the cost and make installation and debugging difficult

Embodiment Construction

[0009] The structure of the hinged multi-dimensional electric field sensor is shown in Fig. 1. Fig. 2.1 is a schematic diagram of the structure of the present invention for measuring one-dimensional electric field signals; Fig. 2.2 is a schematic diagram of the structure of the present invention for measuring two-dimensional electric field signals; Fig. 2.3 is the present invention Schematic diagram of the structure for measuring three-dimensional electric field signals

[0010] When the hinged multi-dimensional electric field sensor is used to measure one-dimensional electric field, the system can be simplified as follows:

[0011] The sensor is mainly composed of two parts: the driving part and the sensing part. The sensing part includes a shield electrode 3, a sensing electrode 4, a hinge 5 and a base 6. The sensing electrode 4 is installed on the base 6, and the shielding electrode 3 is installed on the base 6 through a hinge 5. The shield electrode 3 is made of conductive mat...

Abstract

Disclosed is a hinged multi-dimensional electric field sensor which comprises driving part and sensing part. Wherein the sensing part comprises bucking electrode (3), sensing electrode (4), linkage (5) and base plate (6); the sensing electrode (4) is installed on the base plate (6) and the bucking electrode (3) is installed on the base plate (6) via hinge (5). The invention is characterized in that the sensor employs hinged structure to make the bucking electrode rotate relative to the sensing electrode while sensor is working; it has accurate positioning and don't need to open holes on the bucking electrode to improve the stability of bucking electrode while rotating with high frequency.

Description

Technical field [0001] The invention designs sensors, and particularly relates to hinged multi-dimensional electric field sensors. Background technique [0002] Electric field sensors are widely used in various fields such as atmospheric circulation research, weather forecasting, air pollution detection, and lightning fact detection. According to its working principle, it can be roughly divided into two types: mechanical and optical. The early mechanical electric field sensors mainly include rotary vane type, double ball type, etc., which have the advantages of simple structure and convenient production; the disadvantage is large size, which brings poor portability, high cost, and small range of use, etc. defect. The advantages of the optical electric field sensor are that the system has a faster response speed and low noise. The disadvantage is that the manufacturing accuracy is high, which leads to higher costs and more complicated installation, and its detection range is gener...
