[0024] The housing is equipped with a display screen and operation buttons that work in conjunction with the controller. The display screen is used to display the relevant electrical parameters of the single-phase power distribution cabinet.

[0025] The audible and visual alarm component is an audible and visual alarm device, the connection component is an 8-channel switch quantity transmission path, the communication component is a wireless transceiver, and the command transmission component is a command input device.

[0026] The controller is an STM32F103C8T6 with 64 pins. The controller is connected to the instruction input device via pin 4, to the switch signal transmission path via pin 15, to the wireless transceiver via pins 20 and 21, and to the audible and visual alarm via pins 37 and 38.

[0027] The instruction input device is model TLP290 and has four pins. Pin 1 of the instruction input device is connected to the fault threshold instruction input pin of the host computer through the tenth resistor. A ninth resistor and a fourth capacitor are connected in parallel between pin 1 and pin 2 of the instruction input device. A fifth capacitor and an eighth resistor are connected in parallel between pin 3 and pin 4 of the instruction input device.

[0028] The wireless transceiver is model ESP8266 and has 8 pins. Pin 4 of the wireless transceiver is connected to pin 21 of the controller, and pin 8 of the wireless transceiver is connected to pin 20 of the controller.

[0029] The audible and visual alarm includes a first electromagnetic relay and a second electromagnetic relay connected in parallel. The first electromagnetic relay is connected to pin 38 of the controller, and the second electromagnetic relay is connected to pin 37 of the controller. A red indicator light is connected to the first electromagnetic relay, and a buzzer is connected to the second electromagnetic relay.

[0030] The switch quantity transmission paths are configured in parallel, and each switch quantity transmission path is equipped with a check bit code.

[0031] The housing is an insulating housing used to eliminate electrical interference.

[0032] The working principle of the cloud alarm device for power outage and phase loss in a water conservancy project power line in this embodiment is as follows: Based on the unified control function of the controller hardware, and in conjunction with multiple types of electrical functional components, it is integrated and installed in the power distribution room to build a related electrical structure and transmission network. When a line failure occurs, it can quickly respond and issue audible and visual alarm information. At the same time, it can perform remote communication interaction to realize cloud alarm, so as to prompt staff to take effective measures in a timely manner to avoid electric shock accidents and improve the overall safety of the device.

[0033] The overall solution includes a housing, within which a controller is housed. The controller is electrically connected to an audible and visual alarm component, a connection component, a communication component, and a command transmission component. The audible and visual alarm component issues an audible and visual alarm when a single-phase ground fault is detected. The connection component establishes a detection path between the controller and the distribution cabinet, enabling the controller to collect and compare the relevant electrical parameters of the single-phase power supply in the distribution cabinet. The communication component establishes a network path between the controller and a host computer to transmit detection data and results to the host computer. The command transmission component is located between the controller and the host computer to transmit the fault threshold values ​​of the single-phase electrical parameters of the distribution cabinet to the controller.

[0034] The core component is the controller, model STM32F103C8T6, which has 64 pins. The controller is connected to the instruction input device through pin 4, to the switch signal transmission path through pin 15, to the wireless transceiver through pins 20 and 21, and to the audible and visual alarm through pins 37 and 38. This completes the overall hardware circuit, which is used to accurately identify and detect single-phase grounding faults.

[0035] In practical applications, the host computer is electrically connected to the controller through a wireless transceiver and a command input device. First, the fault thresholds for the single-phase power parameters of the distribution cabinet are set. Generally, the single-phase power parameters of the distribution cabinet include voltage parameters, current parameters, and power parameters.

[0036] The connection component establishes a detection path between the controller and the distribution cabinet, enabling the controller to collect the relevant electrical parameters of the single-phase power in the distribution cabinet and compare them with the fault threshold of the relevant electrical parameters of the single-phase power in the distribution cabinet. When a single-phase power fault occurs, the real-time relevant electrical parameters of the single-phase power in the distribution cabinet will fluctuate significantly, which can be clearly identified and judged.

[0037] When a single-phase ground fault occurs, the controller transmits control commands to the audible and visual alarm, causing the alarm to activate and emit audible and visual alarm information to alert staff. At the same time, with the help of the wireless transceiver, relevant information and detection results are transmitted to the host computer to achieve remote communication and interaction.

[0038] The housing is equipped with a display screen and operation buttons that work in conjunction with the controller. The display screen is used to display the relevant electrical parameters of the single-phase power distribution cabinet, and the operation buttons can be used to view historical related information data. In this application, a switch quantity transmission path is used, so that obvious data changes will appear once a single-phase power fault occurs, which is convenient for identification.

[0039] Preferably, the instruction input device is model TLP290, which has four pins. Pin 1 of the instruction input device is connected to the fault threshold instruction input pin of the host computer through a tenth resistor. A ninth resistor and a fourth capacitor are connected in parallel between pin 1 and pin 2 of the instruction input device. A fifth capacitor and an eighth resistor are connected in parallel between pin 3 and pin 4 of the instruction input device. Pin 3 of the instruction input device is connected to pin 4 of the controller.

[0040] Preferably, the wireless transceiver is an ESP8266, which has 8 pins. Pin 4 of the wireless transceiver is connected to pin 21 of the controller, and pin 8 of the wireless transceiver is connected to pin 20 of the controller, which enables the establishment of a stable transmission network between the host computer and the controller.

[0041] Preferably, the audible and visual alarm includes a first electromagnetic relay and a second electromagnetic relay connected in parallel. The first electromagnetic relay is connected to pin 38 of the controller, and the second electromagnetic relay is connected to pin 37 of the controller. A red indicator light is connected to the first electromagnetic relay, and a buzzer is connected to the second electromagnetic relay. The relay-driven method is used to ensure a fast and accurate response to the audible and visual alarm information.

[0042] It should be noted that the switch quantity transmission paths are set in parallel, and each switch quantity transmission path is equipped with a check bit code, which can accurately identify the corresponding detection data source; the housing is made of insulating housing to eliminate electrical interference and further improve detection accuracy.

[0043] In summary,
