Description

Technical Field

[0001] This utility model relates to the field of power system monitoring, and in particular to a power outage and restoration status monitoring device. Background Technology

[0002] In power system operation, real-time monitoring of power outage and restoration status is crucial for ensuring the safe and stable operation of the system. Existing power outage and restoration status monitoring systems mainly rely on wired connections for data transmission, which has many shortcomings in practical applications.

[0003] First, wired connections limit the flexibility and scalability of monitoring systems. In complex power system environments, wiring is often cumbersome, increasing the difficulty of installation and maintenance, and limiting the scope of system deployment.

[0004] Secondly, traditional monitoring systems lack real-time capabilities and remote access. When power outages or restorations occur, relevant information cannot be transmitted to the remote monitoring center in a timely manner, which seriously affects the system administrators' ability to monitor the power system status in real time and respond quickly.

[0005] Furthermore, existing monitoring systems are typically limited in function, capable only of basic status monitoring and lacking auxiliary functions such as data storage, display, and system debugging. This functional limitation makes it difficult for the system to meet diverse monitoring needs in practical applications and also increases the difficulty of system maintenance and upgrades.

[0006] These problems have led to low efficiency in power system monitoring, making it difficult to detect and handle abnormal power outages and restorations in a timely manner, and increasing potential safety hazards in power system operation. At the same time, the system's scalability and adaptability are insufficient to meet the increasingly complex monitoring needs of the power system. Utility Model Content

[0007] The purpose of this invention is to provide a power outage and restoration status monitoring device to solve the problem that the reliance on wired connections in the prior art leads to limited testing flexibility and real-time performance.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The monitoring device includes a base plate for supporting and fixing various functional modules. A control unit, a communication module, and a power outage / restoration status detection unit are disposed on the base plate. The control unit is an STM32F103 series microcontroller used to process power outage / restoration status signals and control wireless transmission. The communication module is a Bluetooth module used to wirelessly transmit power outage / restoration status signals to a remote receiving device. The communication module is electrically connected to the control unit. The power outage / restoration status detection unit is used to detect the status of external power outage / restoration circuits and is electrically connected to the control unit.

[0010] Furthermore, the control unit has two UART interfaces and a GPIO interface, wherein the first UART interface is used for data communication with the communication module, and the GPIO interface is used to receive the status signal of the power outage and restoration status detection unit.

[0011] Specifically, the second UART interface of the control unit is used as a debugging interface for program burning and system debugging.

[0012] Furthermore, the substrate is provided with a debugging port, which is used for connecting external debugging equipment and is electrically connected to the second UART interface.

[0013] Furthermore, the communication interface between the communication module and the control unit is configured with a baud rate parameter to ensure the stability of data transmission.

[0014] In addition, the communication interface between the communication module and the control unit is configured with data bit parameters and stop bit parameters to ensure the accuracy of data transmission.

[0015] Specifically, the power outage / restoration status detection unit is electrically connected to an external circuit.

[0016] This invention integrates an STM32F103 series microcontroller as a control unit, a Bluetooth module as a communication module, and a power outage / restoration status detection unit on a substrate, and organically combines these units through electrical connections. This achieves real-time monitoring and wireless transmission of power outage / restoration status, overcoming the shortcomings of traditional wired connection methods in terms of wiring and installation maintenance, and improving the system's flexibility and reliability.

[0017] By configuring the two UART interfaces and GPIO interfaces of the control unit, setting the baud rate, data bits, and stop bits of the communication interface, and providing a dedicated debugging interface and external connection terminals, the system achieves excellent communication performance and ease of debugging and maintenance. It also ensures reliable connection to external power-off / restoration circuits, further enhancing the system's practicality and engineering application value. Attached Figure Description

[0020] like Figure 1 As shown, the monitoring device of this utility model includes a base plate (not shown in the figure), which is used to integrate and fix various functional modules. A control unit, a communication module, and a power outage / restoration status detection unit are disposed on the base plate. The control unit uses an STM32F103 series microcontroller, which has multiple UART interfaces and GPIO interfaces, operates at a frequency up to 72MHz, and has strong data processing capabilities, capable of meeting the real-time processing requirements of power outage / restoration status signals.

[0021] The communication module is a Bluetooth module, specifically models such as HC-05, HC-06, or CC2541. In this embodiment, the HC-05 Bluetooth module is preferred. This model features a master-slave integrated design, allowing for easy configuration as either a master or slave, with a communication distance of up to 10 meters and low cost, making it particularly suitable for the application scenario of this invention. The communication module is electrically connected to the control unit; the power outage / restoration status detection unit is also electrically connected to the control unit.

[0022] The control unit has two UART interfaces and a GPIO interface. The TX pin of the first UART interface is connected to the RX pin of the Bluetooth module, and the RX pin of the first UART interface is connected to the TX pin of the Bluetooth module, enabling bidirectional data communication between the control unit and the Bluetooth module. The GPIO interface is configured in input mode and is electrically connected to the power outage / restore status detection unit to receive power outage / restore status signals.

[0023] In this embodiment, the second UART interface of the control unit is used as a debugging interface, with its TX and RX pins connected to corresponding pins of the debugging port for program burning and system debugging. The substrate has a debugging port, which is electrically connected to the second UART interface. To facilitate debugging and program updates, the debugging port uses a standard 4-wire serial interface, including four pins: TX, RX, VCC, and GND.

[0024] The communication module has configurable communication parameters, including baud rate parameters, data bit parameters, and stop bit parameters; the communication module supports transparent transmission mode and can automatically complete data transmission and reception.

[0025] The power outage / restoration status detection unit is equipped with terminals for connection to an external power outage / restoration circuit.

[0026] The working process of this embodiment is as follows:

[0027] 1. Power-on initialization: The control unit completes the initialization configuration of the GPIO and UART interfaces.

[0028] 2. Status Detection: The power outage and restoration status detection unit monitors the status of the external power outage and restoration circuit in real time. When the status changes, it sends a status signal to the control unit through the GPIO interface.

[0029] 3. Wireless transmission: The control unit sends data to the Bluetooth module through the first UART interface, and the Bluetooth module sends the data wirelessly to the remote receiving device.

[0030] In practical applications, when the state of the external power outage / restoration circuit changes, the power outage / restoration status detection unit collects status signals through the terminal blocks and transmits the signals to the control unit via the GPIO interface. The control unit then sends the data to the communication module via the first UART interface. The communication module wirelessly transmits the data, enabling remote monitoring of the power outage / restoration status.
