It should be noted that similar numbers and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0028] Example 1: Please refer to Figure 1-Figure 6A wireless voltage sensor comprises an outer shell 1, a conical sleeve 2 is arranged at the lower end of the outer shell 1, a fixing nut 3 is arranged above the conical sleeve 2, a connecting line 4 is arranged on the side of the fixing nut 3, a sensor circuit board 5 is arranged inside the outer shell 1, a circuit board fixing mechanism 16 is arranged on the sensor circuit board 5, a connecting piece 161 is arranged on the circuit board fixing mechanism 16, a U-shaped groove 162 is opened on the connecting piece 161, a V-shaped clamping plate 163 is arranged at the lower end of the connecting piece 161, and a positioning block 17 is arranged on the inner surface of the sensor circuit board 5.

[0029] The sensor circuit board 5 is provided with a wireless voltage sensing chip 6, which is connected to the RF transceiver 7 circuit, and the RF transceiver 7 is connected to the wireless transceiver chip 13 circuit. The RF transceiver 7 is connected to the lithium battery 8 circuit. The wireless voltage sensing chip 6 is connected to the diode 9 circuit.

[0030] The wireless voltage sensing chip 6 is connected to the data storage chip 10 in circuit, and the data storage chip 10 is connected to the clock oscillator 11 in data. A low-pass filter 12 is provided on the sensor circuit board 5. The RF transceiver 7 is connected to the RF antenna 14 in circuit. The diode 9 is connected to the resistor 15 in circuit. The lithium battery 8 is connected to the clock oscillator 11 and the low-pass filter 12 in circuit.

[0031] By arranging a conical sleeve 2 at the lower end of the outer shell 1 and arranging a fixing nut 3 above the conical sleeve 2, this design allows the sensor to be conveniently fixed to various devices or structures, thereby improving the flexibility and convenience of installation. Secondly, the circuit board fixing mechanism 16, the connector 161, the U-shaped groove 162 and the V-shaped clamping plate 163 on the sensor circuit board 5 together form a stable fixing structure, which can ensure that the sensor circuit board 5 remains stable during operation and is not prone to loosening or displacement. This stable fixing method helps to improve the measurement accuracy and reliability of the sensor.

[0032] The wireless voltage sensing chip 6 provided on the sensor circuit board 5 can sense voltage changes in real time, and transmit data to the wireless transceiver chip 13 through the radio frequency transceiver 7 to realize wireless data transmission. This wireless transmission method avoids the cumbersomeness and limitations that may be brought about by traditional wired transmission, improves the efficiency and flexibility of data transmission, and the lithium battery 8 serves as a power source to provide a stable power supply for the entire sensor. The lithium battery 8 has the advantages of small size, light weight, and high energy density, which can meet the requirements of long-term stable operation of the sensor. The connection between the wireless voltage sensing chip 6 and the diode 9, the data storage chip 10, and the clock oscillator 11 components further enhances the functionality and stability of the sensor. The diode 9 can protect the circuit from damage caused by voltage fluctuations, the data storage chip 10 can record historical data for subsequent analysis, and the clock oscillator 11 provides an accurate time reference.

[0033] Finally, the setting of the low-pass filter 12 can effectively filter out high-frequency noise, improve signal quality, and further improve the measurement accuracy of the sensor. The connection between the RF transceiver 7 and the RF antenna 14 ensures the stable transmission of the wireless signal, so that the sensor can work normally in various environments.

[0034] During the use of the utility model, the user first selects an appropriate installation position according to actual needs. Align the conical sleeve 2 of the sensor with the installation point, rotate the fixing nut 3, so that the conical sleeve 2 fits tightly on the installation surface, and the sensor is firmly fixed. Connect the connecting wire 4 to the sensor to ensure that the connection is stable and reliable. According to the specific application scenario, configure the parameters of the sensor, such as sampling frequency and data transmission interval. After the sensor is started, the wireless voltage sensing chip 6 begins to sense the voltage changes at the location in real time. The sensed voltage data is processed by the circuit on the circuit board, including filtering and amplification steps to improve the accuracy of the data. The processed voltage data is wirelessly transmitted through the radio frequency transceiver 7 and sent to the receiving device or system. The receiving device or system can display the voltage data in real time and perform further analysis and processing.

[0035] The working principle of the wireless voltage sensor is based on voltage sensing, signal processing and wireless transmission technology. The wireless voltage sensing chip 6 is the core component of the sensor, which can sense the voltage changes at the location in real time. When the voltage changes, the sensing chip converts the change into an electrical signal to provide raw data for subsequent measurement and analysis. The circuit on the sensor circuit board 5 further processes the sensed electrical signal. The diode 9 element protects the signal to prevent overvoltage or undervoltage from damaging the circuit. The low-pass filter 12 filters the signal to remove high-frequency noise and improve the purity of the signal. The data storage chip 10 can record voltage data over a period of time for subsequent analysis or troubleshooting. The radio frequency transceiver 7 is responsible for transmitting the processed voltage data wirelessly. Through the connection with the wireless transceiver chip 13, the data is sent to the designated receiving device or system. The radio frequency antenna 14 enhances the transmission range and stability of the wireless signal, ensuring that the data can be accurately and reliably transmitted to the target location. The lithium battery 8 serves as the power source of the sensor and provides a stable power supply. The clock oscillator 11 provides an accurate time reference for the sensor to ensure the synchronization of data acquisition and transmission.

[0036] The U-shaped groove 162 on the connecting piece 161 can be used to conveniently fix the sensor circuit board, ensuring that the circuit board is not easily loosened or displaced when subjected to external force or vibration. The U-shaped groove 162 makes the installation and removal process of the circuit board simple and quick, thereby improving work efficiency. The structure of the U-shaped groove 162 can adapt to circuit boards of different sizes and shapes, thereby improving the versatility of the fixing mechanism. In addition to the fixing effect of the U-shaped groove 162, the V-shaped card plate 163 can facilitate the fixing of the circuit board buckle installation, making the circuit board more stable. When subjected to impact or vibration, the V-shaped card plate 163 can play a certain buffering role and reduce damage to the circuit board. The structure of the V-shaped card plate 163 can cooperate with a specific part on the circuit board to achieve precise positioning and ensure the accuracy of circuit board installation.

[0037] The positioning block 17 works together with the U-shaped groove 162 and the V-shaped clamping plate 163 on the connecting member 161 to ensure that the position of the circuit board in the fixing mechanism is accurate. The close fit between the positioning block 17 and the fixing mechanism can further improve the stability of the circuit board and prevent it from shifting or shaking during use. The positioning block 17 makes the installation process of the circuit board simpler and clearer, reducing errors and uncertainties during the installation process.
