[0036] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0037] A specific orthogonal power failure warning device and method provided in an embodiment of the present application will be described below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, the orthogonal power-on warning device provided in the embodiment of the present application includes: multiple electric field sensors 1, air pressure sensors 2, acceleration sensors 3, signal processing circuits 4, processing circuits 5 and alarm circuits 6, wherein the multiple electric field sensors 1, air pressure sensors 2, and acceleration sensors 3 are respectively connected to the input end of the signal processing circuit 4, and the output end of the signal processing circuit 4 and the alarm circuit 6 are respectively connected to the processing circuit 5; wherein the multiple electric field sensors 1 are orthogonally arranged;

[0039] The multiple electric field sensors 1 collect multi-faceted electric field strength signals at the scene, the air pressure sensor 2 obtains the air pressure signal, and the acceleration sensor 3 obtains the attitude signal. The signal processing circuit 4 processes the multi-faceted electric field strength signal, attitude signal and air pressure signal respectively. The processing circuit 5 converts the processed multi-faceted electric field strength signal from an analog signal to a digital signal, and then performs Fourier transform on the digital signal to extract the effective value of the digital signal. The multi-faceted orthogonal sensor value is calculated according to the effective value, and the comprehensive electric field strength and the relative position of the charged body are determined according to the multi-faceted orthogonal sensor value. The comprehensive electric field strength, the relative position of the charged body, the attitude signal and the air pressure signal are combined to determine whether the warning conditions are met. When it is determined that the warning conditions are met, a warning signal is generated, and the warning signal is sent to the alarm circuit 6 for warning.

[0040] The working principle of the orthogonal power-on warning device is as follows: multiple electric field sensors 1 are provided in this application, and the multiple electric field sensors 1 are arranged in an orthogonal structure. The multiple electric field sensors 1 can collect multi-faceted electric field strength signals, and the posture signals and air pressure signals of the sensor collection devices in the pressure sensor 2 and the acceleration sensor 3 are respectively processed by the signal processing circuit 4. Then, the processing circuit 5 receives the processed multi-faceted electric field strength signals, posture signals and air pressure signals. The processing circuit 5 first converts the multi-faceted electric field strength signals into digital signals, and then extracts the effective value of the multi-faceted electric field strength signals through Fourier transform, thereby calculating the multi-faceted orthogonal sensor values ​​according to the effective value, and determining the comprehensive electric field strength and the relative position of the charged body according to the multi-faceted orthogonal sensor values. Combined with the comprehensive electric field strength, the relative position of the charged body, the posture signal and the air pressure signal, it is determined whether the warning conditions are met. When it is determined that the warning conditions are met, a warning signal is generated, and the warning signal is sent to the alarm circuit 6 for warning.

[0041] In summary, the multifaceted electric field sensor 1 in this application forms a three-dimensional space with an orthogonal structure, and encapsulates all components and circuit boards in the three-dimensional space. This structural innovation forms an excellent electrostatic shielding effect, eliminates the electromagnetic interference of its own circuit on the electric field to be measured, and uses the multi-orthogonal electric field sensor 1 to solve the consistency of detection data. It uses multi-dimensional vector detection of the spatial electric field and calculates the comprehensive electric field strength through vector sum. Regardless of the angle direction of the early warning module, the spatial position remains unchanged, which can ensure that the comprehensive detection value is relatively consistent. It can be understood that the closed cube formed by the multifaceted orthogonal electric field sensor is an equipotential body in space, and the internal components do not affect the external sensor signal. It has a good electrostatic shielding effect and ensures the accuracy of the detection signal.

[0042] In some embodiments, the processing circuit 5 comprises an ADC conversion module 51, a signal extraction module 52 and a processor 53, the ADC conversion module 51 is connected with one end of the signal extraction module 52, and the other end of the signal extraction module 52 is connected with the processor 53;

[0043] The ADC conversion module 51 is used to convert the processed multi-surface electric field intensity signal from an analog signal to a digital signal;

[0044] The signal extraction module 52 is used to extract the effective value of the digital signal through Fourier transform;

[0045] The processor 53 is used to calculate the multi-surface orthogonal sensor value according to the effective value, determine the comprehensive electric field intensity and the relative position of the charged body according to the multi-surface orthogonal sensor value, judge whether the pre-warning condition is met by combining the comprehensive electric field intensity, the relative position of the charged body, the attitude signal and the air pressure signal, generate a pre-warning signal when it is determined that the pre-warning condition is met, and send the pre-warning signal to the alarm circuit 6 for pre-warning.

[0046] In the present application, the vector data is detected by the multi-surface orthogonal electric field sensor 1, and the comprehensive field strength is calculated and obtained by the processor 53. The electric field intensity signal is related to the multi-sensing data. Since the detection data is a vector, the detection signal size difference caused by the different sensing position angles of the same space point is eliminated, and the consistency of the detection equipment is improved. It should be noted that unlike most pre-warning equipment on the market which simply alarms by comparing the electric field detection signal with a threshold value, the orthogonal electric pre-warning device provided in the present application not only has high consistency and accurate electric field signal, but also provides air pressure signal by the air pressure sensor 2 and provides attitude signal by the acceleration sensor 3, realizes pre-warning by comprehensive algorithm, realizes progressive pre-warning, dynamically reminds the relative position of the charged body during the movement, and the pre-warning function is more accurate.
