[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, this utility model is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0029] Example 1
[0030] Please see Figures 1-5 As shown, this embodiment is a comprehensive power monitoring and safety early warning device for mining areas, including a base plate 1, a data acquisition unit 8 and a data processing unit 11. The data acquisition unit 8 is provided on the upper end of the base plate 1, the data processing unit 11 is provided on one side of the data acquisition unit 8, the human-machine interaction unit 10 is provided on one side of the data processing unit 11, and the early warning judgment unit 13 is provided on one side of the human-machine interaction unit.
[0031] When using this device, screws are used in conjunction with positioning holes 3 to fix the device to one side of the wall. Then, the wires of the detection circuit are connected to the various processing units inside the device through through holes 12. The internal processing system of the device is used to monitor and warn of voltage and current.
[0032] Voltage and current warning judgment methods:
[0033] a. High-precision voltage transformers and current transformers are used to collect voltage and current data of power lines in real time. The sampling frequency is set according to the fluctuation characteristics of the power system, such as once every millisecond, to ensure data continuity and accuracy.
[0034] b. Filter the acquired data to remove high-frequency noise interference. Use a Butterworth low-pass filter with a cutoff frequency set according to the main frequency of the power signal, usually several times 50Hz, to smooth the data curve and highlight the true signal characteristics.
[0035] c. Based on historical operating data, use statistical methods to calculate the mean and standard deviation of voltage and current, such as operating data of the same time period and line in the past week. The initial warning threshold is set as follows: upper limit threshold = μ + kσ, lower limit threshold = μ - kσ, where the value of k is taken between 2 and 3 according to the system's sensitivity to warnings. For example, for hospital power supply lines with high stability requirements, k is taken as 2.5.
[0036] d. Establish a dynamic update mechanism. At fixed intervals, recalculate the mean and standard deviation based on newly collected sufficient data, and update the threshold to adapt to seasonal and diurnal variations in power load.
[0037] f. Use the moving average method to analyze the short-term trend of voltage and current data, calculate the average value of multiple consecutive collection points as the trend value, compare the current trend value with the historical trend of the same period, if the slope deviation exceeds a certain angle, it indicates possible abnormality, such as the current rising too fast due to the start-up of an industrial production line.
[0038] g. Introduce a rate of change index to calculate the rate of change of voltage and current at adjacent sampling points in real time. If multiple consecutive rates of change exceed the preset range, an early warning will be triggered immediately to capture sudden fault impact signals.
[0039] h. Considering the interrelationship between voltage and current, a correlation model is constructed based on Ohm's law and the characteristics of the power system. Under normal operating conditions, the two should fit a specific functional relationship. If a sudden drop in voltage is detected but the current does not increase accordingly, there may be an open circuit or poor contact in the line, and an early warning will be issued.
[0040] i. By combining the operating status of power equipment and environmental parameters, when the equipment overheats, the resistance increases and the current will be abnormal even if the voltage is stable. At this time, the temperature monitoring is linked to accurately locate the potential fault and issue a composite early warning message.
[0041] Example 2
[0042] Please see Figures 1-5 As shown, this embodiment, based on embodiment 1, further includes: a top cover 4 on one side of the base plate 1, and a sealing ring 2 on the surface of the base plate 1. The width of the sealing ring 2 is equal to the thickness of the top cover 4. After the top cover 4 is fixed to the base plate 1 with screws, the design of the sealing ring 2 will achieve the effect of waterproofing and moisture-proofing at the edge, preventing the long-term exposure to a humid environment from affecting the normal operation of the internal circuit. The sealing ring 2 is a three-layer design.
[0043] A through-hole 12 is provided in the center of the surface of the base plate 1. A communication unit 9 is provided on one side of the base plate 1. The communication unit 9 includes a wireless interface, a modem, and a communication control device. The wireless interface is mainly a Wi-Fi module, which connects to a wireless network via radio frequency signals to enable communication between the device and the network or other devices. The operating frequency band is generally 2.4GHz and 5GHz. The Bluetooth module can be used for short-range data transmission, usually within a range of about 10 meters, facilitating pairing and connection between the device and surrounding devices, such as mobile phones and Bluetooth headsets. For some long-range wireless communication, there will be a cellular network module, such as a 4G LTE or 5G module, enabling the device to access the mobile Internet. The modem is essential for communication methods that transmit digital data through analog signals (such as some traditional telephone line communication). It can modulate digital signals into analog signals for transmission on the communication line, and then demodulate the analog signals back into digital signals at the receiving end. The communication control device is responsible for managing and controlling the data transmission and reception of the communication interface, including establishing communication links, negotiating communication protocols, and handling communication errors. For example, during Wi-Fi communication, the communication controller will handle operations such as connection and authentication with the wireless router, and will also perform data packetization and encapsulation processing.
[0044] The base plate 1 has positioning holes 3 arranged in a ring array at the edge of its surface. The positioning holes 3 can fix the screws to the wall and the screws to the top cover 4.
[0045] A display screen 5 is provided on one side of the top cover 4. An indicator light 6 is provided at the bottom of the display screen 5. A button 7 is provided at the bottom of the indicator light 6. The display screen 5, the indicator light and the button 7 are electrically connected to the human-machine interaction unit 10. The staff can view the device status and warning information through the human-machine interaction unit 10, and can also set the device and adjust the parameters. It is like a "control window" to facilitate the interaction between people and the device.
[0046] The data acquisition unit 8 also includes a current sensor, a voltage sensor, a signal conditioning circuit, and an analog-to-digital converter. The sensor is used to sense current or voltage signals. For example, a current transformer can measure current, and a voltage transformer or voltage divider is used to measure voltage. The signal conditioning circuit can amplify and filter the weak or potentially interference-containing signals output by the sensor to improve signal quality. The analog-to-digital converter converts the conditioned analog signal into a digital signal for convenient subsequent processing, storage, and transmission.
[0047] The human-computer interaction unit 10 also includes a processing assembly and a controller.
[0048] The data processing unit 11 includes a processor, a signal memory, and a signal transmitter. The processor is the core component of data processing and can perform various arithmetic and logical operations, such as addition, multiplication, and comparison. It reads instructions and data from memory, processes them, and then writes the results back to memory, controlling the order and rhythm of the entire data processing flow. The signal memory can store the sensed signals for easy retrieval later. The signal transmitter can transmit signals to the back-end control system.
[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
