[0060] Figure 3 FIG. 2 shows a schematic diagram of the structure of a second three-dimensional electric field detection device provided by a preferred embodiment of the present invention. Figure 3 As shown, in some embodiments, a three-dimensional electric field detection device is different from the three-dimensional electric field detection device described in the above embodiments in that:

[0061] Each signal sensing part includes a sensing electrode, a supporting part and a wire, wherein:

[0063] Specifically, each sensing electrode is connected to three orthogonal surfaces of the shell 1 through a supporting portion, wherein the area of ​​the sensing electrode is smaller than the area of ​​the outer wall surface corresponding thereto, so as to avoid the sensing electrode blocking the light source 14 and the buzzer 13 on the outer wall surface, thereby facilitating the detection of the corresponding sound and light prompts emitted by the light source 14 and the buzzer 13.

[0064] When the number of the electric field measurement module 8 is one, each sensing electrode inputs each current signal into the electric field measurement module 8 through a wire, and obtains the digitized DC voltage signal in the X direction, the Y direction and the Z direction through the electric field measurement module 8. When the number of the electric field measurement modules 8 is the same as the number of the sensing electrodes, each sensing electrode is connected to the corresponding electric field measurement module 8 through a wire to input the current signal into the electric field measurement module 8 to obtain the corresponding digitized DC voltage signal. The microprocessor 7 synthesizes the digitized DC voltage signal in the X direction, the digitized DC voltage signal in the Y direction and the digitized DC voltage signal in the Z direction obtained above into an electric field strength value.

The external terminal analyzes the received position information (for example: the position information is the longitude and latitude information of the three-dimensional electric field detection device in the air electric field). When it is determined that the position information of the three-dimensional electric field detection device is consistent with the preset position information, the external terminal sends the position information analysis result to the control part. The control part receives the position information analysis result sent by the external terminal, and generates a prompt instruction according to the analysis result. Each sound and light prompt component sends a sound and light prompt according to the received prompt instruction.

[0073] Specifically, when each signal sensing part includes a sensing electrode, a support part and a wire, the current signal sensed by the sensing electrode is input into the electric field measurement module via the wire. When each signal sensing part is a MEMS electric field sensitive unit, the current signal sensed by the MEMS electric field sensitive unit is input into the electric field measurement module via the wire.

[0074] S3. The control part converts the input current signals into digital DC voltage signals, and synthesizes the digital DC voltage signals into electric field strength values.

[0075] Specifically, the current signal is input into the IV conversion unit and converted into an AC voltage signal by the IV conversion unit. The AC voltage signal is input into the differential amplifier unit to remove the interference signal and generate an amplified AC voltage signal with a signal strength greater than the AC voltage signal. The amplified AC voltage signal is input into the waveform conversion module, and the peak value of the signal is detected to obtain a simulated DC voltage signal. The simulated DC voltage signal is input into the analog-to-digital conversion unit, and the analog-to-digital conversion unit converts the simulated DC voltage signal into a digital DC voltage signal. The microprocessor uses the following formula to synthesize the above-obtained digital DC voltage signal in the X direction, the digital DC voltage signal in the Y direction, and the digital DC voltage signal in the Z direction into an electric field strength value, where:

[0076]

[0077] Wherein, E is the electric field strength value, Ex is the digitized DC voltage signal in the X direction, Ey is the digitized DC voltage signal in the Y direction, and Ez is the digitized DC voltage signal in the Z direction.
