Description

Technical Field

[0001] The utility model relates to the technical field of AC power supply detection devices, in particular to a three-phase AC power supply monitoring wireless alarm device. Background Art

[0002] During oilfield production, some operating areas typically use a single-well production method. This type of production method is often located near residential areas, and each single well is typically connected to the same transformer as the civilian power supply during power connection. In the prior art, the power supply of the oil well is typically directly connected to a civilian transformer. However, after the oil well is connected to the civilian transformer, the excessive power consumption of the oil well causes the civilian voltage to carry an unstable load, often resulting in overvoltage, undervoltage, three-phase imbalance, and phase loss faults, causing civilian electrical appliances near the oil well, such as air conditioners and televisions, to burn out, resulting in significant economic losses. At the same time, oil wells can be temporarily shut down due to circuit faults. In the prior art, the inability to obtain fault information in a timely manner after a circuit fault causes staff to be unable to detect the fault status in a timely manner, and can even cause the oil well to be shut down for several consecutive days, seriously affecting the normal progress of production work and causing huge economic losses. Therefore, in response to the above shortcomings, a three-phase AC power supply monitoring wireless alarm device is proposed. Summary of the Invention

[0003] The purpose of this utility model is to provide a three-phase AC power monitoring wireless alarm device to overcome the problems of the prior art that, after being connected to a civilian transformer, the transformer pressure is easily unstable and the surrounding civilian electrical appliances are burned out, and the defects of the prior art that the shutdown status of the oil well cannot be discovered in time after a circuit failure, resulting in huge economic losses.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-2 As shown, the utility model provides a three-phase AC power monitoring wireless alarm device, comprising:

[0022] The device body 1 houses a main power supply 5, a transmitter power supply 6, a mainboard 4, a data acquisition board 7, and a wireless communication module 10. The main power supply 5 is used to connect to the on-site power supply, directing current from the on-site low-voltage power supply into the device and supplying power to the device. The transmitter power supply 6 converts the voltage of the civilian power supply into an appropriate operating voltage for the various components within the device. The mainboard 4, the device's primary operating component, processes and calculates input data according to pre-set calculation formulas and programs. Before operation, the mainboard 4 can be connected to a computer and the program within it can be modified to alter its calculation method during operation, thereby ensuring that its output signal meets operational requirements. The data acquisition board 7 collects data according to a pre-set program. The wireless communication module 10 enables wireless signal transmission with other on-site equipment. The input of the main power supply 5 is connected to the three-phase power supply within the low-voltage distribution cabinet, while the output is connected to the transmitter power supply 6 for voltage conversion. The main power supply 5 transmits the power of the three-phase power supply in the low-voltage distribution cabinet to the transmitter power supply 6, and the transmitter power supply 6 converts the 220V three-phase power supply in the low-voltage distribution cabinet into a 24V DC power supply to power the electronic components in the device.

[0023] The output end of the transmitter power supply 6 is connected to the mainboard 4 for power supply. The transmitter power supply 6 transmits the converted DC power to the mainboard 4, which then transmits the power to the various components connected to the mainboard 4 for energy supply. The wireless communication module 10 and the data acquisition board 7 are both connected to the mainboard 4. The data acquisition board 7 sends the collected data to the mainboard 4. The mainboard 4 calculates the electric power of each phase of the three-phase power supply based on the data sent by the data acquisition board 7 according to an internal calculation program and compares it with the normal value. If the calculated result is greater than the normal value, it is determined that the power supply is overvoltage. If the calculated result is less than the normal value, it is determined that the power supply is undervoltage. The calculation and judgment results are then sent to the wireless communication module 10, and the calculation and judgment results of the mainboard 4 are transmitted by the wireless communication module 10 via wireless signals.

[0024] Generally, the main board 4 includes a circuit board body and an ARM microprocessor. The ARM microprocessor is installed on the circuit board body and is used to perform data calculation and processing. Among the data input into the main board 4, the part that needs to be calculated will be selected by the ARM microprocessor, and after the calculation is completed, the data and the calculation results will be output from the main board 4 together.

[0025] The input end of the data acquisition board 7 is connected to the three-phase power supply in the low-voltage distribution cabinet to collect current signals. After the input end of the data acquisition board 7 is connected to the low-voltage distribution cabinet, the current and voltage signals of each phase of the three-phase power supply in the low-voltage distribution cabinet are collected through the input end. The output end of the data acquisition board 7 and the input end of the wireless communication module 10 are both connected to the main board 4 to transmit signals. The data acquisition board 7 sends the collected current and voltage signals to the main board 4. The main board 4 calculates the electric power in each phase of the three-phase power supply based on the measured current and voltage and compares the data between the three phases with the data under normal operating conditions to determine whether there are faults such as overvoltage, undervoltage, three-phase imbalance and phase loss in the three-phase power supply during operation. The main board 4 then transmits the data measured by the data acquisition board 7 and the results of the calculation and judgment by the main board 4 to the wireless communication module 10. The wireless communication module 10 converts the data into wireless signals and sends them to the wireless signal receiving end of other devices.

[0026] It should be noted that the wireless communication module 10 is wirelessly connected to the on-site Internet of Things. Generally, the wireless communication module 10 is always connected to the on-site Internet of Things, so that the device's measurement, calculation, and operation processes are always integrated into the production Internet of Things. Data is transmitted to the data storage terminal via the Internet of Things, allowing other devices in the Internet of Things to access the data in the data storage terminal at any time to perform calculations and other operations as needed, thereby improving the device's practicality.

[0027] like Figure 2 As shown, the device body 1 is equipped with a signal output board 8, the input end of which is connected to the main board 4 to obtain output signals. The signal output board 8 extracts the data results from the calculations, comparisons, and judgments made within the main board 4, converts the resulting data into other signals, and outputs them on-site. This allows personnel on-site to directly access the device's operating status through the output signals from the signal output board 8. Typically, the signal output board 8 converts the resulting data into optical or acoustic signals, which are then displayed or played on-site to inform personnel of the device's real-time operating status. This allows well personnel and residents to accurately determine the cause of circuit faults, promptly recover problems, and address them early.

[0028] The signal output board 8 is equipped with several signal indicators, whose blinking status corresponds to the output signal. The signal output board 8 converts the calculation and judgment results of the main board 4 into optical signals through the signal indicators. By observing the blinking status of the signal indicators, the operator can understand the operating status of the device and the power supply. Typically, there are three groups of signal indicators, arranged in an array on the surface of the device body 1, corresponding to the three operating states of normal operation, power supply overvoltage, and power supply undervoltage. Under normal operating conditions, the signal indicator light group representing normal operation lights up, and the other two groups of indicator lights go out; when the main board 4 calculates and determines that the three-phase power supply in the voltage transformer box is overvoltage, the wireless communication module 10 will send the judgment result, and the control component in the circuit will disconnect the oil well from the three-phase power supply in the low-voltage distribution cabinet after receiving the signal sent by the wireless communication module 10. At the same time, the overvoltage signal indicator light on the signal output board 8 lights up, and the other signal indicator lights go out; when the main board 4 calculates and determines that the three-phase power supply in the voltage transformer box is undervoltage, the wireless communication module 10 will send the judgment result, and the control component in the circuit will disconnect the oil well from the three-phase power supply in the low-voltage distribution cabinet after receiving the signal sent by the wireless communication module 10. At the same time, the undervoltage signal indicator light on the signal output board 8 lights up, and the other signal indicator lights go out.

[0029] It should be noted that, based on actual operational needs, the number of signal indicator lights on the signal output board 8 can be modified before installation, thereby varying the number of operational states that the signal output board 8 can display through the signal indicator lights, thereby improving the practicality of the device. To distinguish between the various groups of signal indicator lights, typically, each group of signal indicator lights has a different color. During field operations, simply observing the color of the illuminated signal indicator lights allows direct access to device operating information, reducing the difficulty of operating the device.

[0030] In the present invention, a storage chip 9 is provided within the device body 1, and the storage chip 9 is connected to the main board 4 to store data. After the storage chip 9 is connected to the main board 4, the main board 4 receives data and performs calculations, and then sends the data and calculation results to the storage chip 9. The storage chip 9 retains the received data as a local backup. On-site personnel can obtain historical operating data of the device and the three-phase power supply within the low-voltage distribution cabinet by reading the data within the storage chip 9. This facilitates on-site personnel to quickly determine the cause of the fault by combining the output signal of the signal output board 8 with the fault cause, thereby improving the efficiency of personnel in handling pumping well accidents caused by three-phase power failures.

[0031] In addition, to facilitate on-site operation of the device, the device body 1 is provided with a display screen 2 and buttons 3. Both the display screen 2 and buttons 3 are connected to a main board 4 to control device operation and display images. The buttons 3 can be used to send control commands to the main board 4, access data from the storage chip 9, and transmit the data to the display screen 2 via the main board 4. The display screen 2 then visualizes the received data and displays it as an image. During on-site operation, workers can directly observe the historical operating data and changing trends of the device and the three-phase power supply by observing the images on the display screen 2, thereby improving work efficiency when reading data.

[0032] Typically, the display screen 2 is a touch screen, which effectively improves the operability of the device. Operations such as data retrieval and data transmission can be performed directly by touching the display screen 2. To reduce the difficulty of operating the device, the buttons 3 are generally located below the display screen 2, arranged along a straight line. When operating the device using the buttons 3, the user can directly observe the operation results and obtain feedback on the display screen 2, thereby improving the accuracy of operating the device using the buttons 3.

[0033] Combine Figures 1 to 2 The following describes in detail the steps of the three-phase AC power monitoring wireless alarm device when it works:

[0034] First, the staff selects and debugs each component according to the on-site working conditions and actual work needs, chooses appropriate electrical components, and then assembles each component on the device body.

[0035] The device was then installed in a low-voltage distribution cabinet on-site. The input terminals of the data acquisition board and the main power supply were connected to the three-phase power supply within the cabinet. The main power supply then directed the current from the three-phase power supply to the transmitter power supply. The 220V current from the three-phase power supply was converted to 24V DC power within the transmitter power supply and then transmitted to the main board to power the various components within the device. Simultaneously, the output terminal of the data acquisition board collected the current and voltage of each phase of the three-phase power supply and transmitted the data to the main board.

[0036] Next, the device is powered on. The data acquisition board transmits the operating parameters of the three-phase power supply to the mainboard, which then calculates the power of the three-phase power supply according to a pre-set program and determines whether the three-phase power supply is operating normally. After the mainboard completes the calculation, it simultaneously transmits the result, the received data, and the judgment structure to the signal output board, storage chip, and wireless communication module. The signal output board controls the on / off state of the signal indicator based on the received data to match the operating status of the three-phase power supply. The storage chip stores the received data to prevent information loss. The wireless communication module, through a wireless connection to the Internet of Things (IoT), transmits the received data to the IoT at the work site for access and use by other devices within the IoT.

[0037] Finally, upon receiving notification of a three-phase power failure, the control component within the IoT disconnects the three-phase power supply from the pumping well. This allows the pumping well to be disconnected from the three-phase power supply before a fault in the low-voltage transformer damages consumer electronics. This interrupts the pumping well's impact on the three-phase power supply and prevents damage to consumer electronics connected to the three-phase power supply within the low-voltage transformer. Simultaneously, the wireless communication module transmits a fault signal to personnel via the IoT, prompting them to promptly inspect and repair the pumping well and the three-phase power supply, thus preventing prolonged downtime.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
