[0003] Furthermore, the inability to locate fault points in real time during power outages leads to low efficiency in manual troubleshooting, resulting in prolonged downtime of electromechanical equipment. Existing devices lack multi-parameter detection interfaces and cannot integrate auxiliary monitoring functions such as temperature and humidity. Utility Model Content

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model proposes a power supply abnormality alarm device, comprising:

[0015] The exposed metal test pads are directly connected to the 3.3V, 5V, 12V and GND nodes.

[0016] Preferably, the charging detection module provides a lithium battery interface and an external power supply interface.

[0017] Preferably, the audible and visual alarm module includes:

[0035] Example 1

[0036] like Figure 1 and Figure 2 As shown, the present invention proposes a power supply abnormality alarm device, comprising:

[0037] Power module 1 is used to output stable 5V and 12V voltages to ensure the power input of the device;

[0038] The charging detection module 3 is configured to connect to an external power source and charge the lithium battery, and to switch to lithium battery power supply when the external power supply is abnormal; wherein, the charging detection module 3 provides a lithium battery interface and an external power supply interface.

[0039] The main control unit 2 is connected to the power module 1 and the charging detection module 3, and is configured to trigger an alarm action based on the voltage status; it is responsible for coordinating the various modules in the circuit and processing the data of each module.

[0040] The audible and visual alarm module 4 responds to the instructions of the main control unit 2 and indicates the power supply status through sound signals and changes in light color.

[0041] The wireless communication module 5, according to the instructions of the main control unit 2, sends power outage alarm information containing location information to a designated terminal via wireless transmission when power supply is abnormal. The designated terminal can be a server. The wireless communication module 5 adopts a 4G module, supports 4G network communication, and transmits alarm information via SMS or voice call.

[0042] Test and maintenance module 6 includes test pads and status indicator LEDs connected to each working voltage for voltage visualization monitoring and maintenance; it is responsible for system testing and maintenance, and determining whether each voltage in the system is stable.

[0043] The reserved interface module 7 provides at least one set of IIC interfaces and four IO interfaces for connecting external sensors or actuators, and is responsible for subsequent expansion functions. The four IO interfaces of the reserved interface module 7 are configured in digital input / output mode for connecting external environmental sensors or equipment status detectors.

[0044] refer to Figure 3 As shown, the test and maintenance module 6 includes:

[0045] Multiple voltage detection branches are set in parallel. Each branch consists of a current-limiting resistor connected in series with an LED, and is connected to the 3.3V, 5V, and 12V voltage output terminals respectively.

[0046] The exposed metal test pads are directly connected to the 3.3V, 5V, 12V and GND nodes.

[0047] Figure 3 The circuit diagram shown is further explained below:

[0048] The 3.3V, 5V, and 12V voltages output by power module 1 are connected to LEDs via resistors (R21, R22, and R23 in the diagram). When the voltage value is normal, the corresponding LED lights up normally; when the voltage value is abnormal, the corresponding LED does not light up. Simultaneously, four pads are directly connected to 12V, 5V, 3.3V, and GND. This allows for troubleshooting of power module 1 by checking the voltage values ​​in case of voltage abnormalities. In summary, the test point module serves two purposes: firstly, to detect whether the voltage module is working properly and outputting normal operating voltage; and secondly, to provide test points for troubleshooting voltage issues when the power supply module malfunctions.

[0049] In this embodiment, the sound and light alarm module 4 includes a buzzer and a dual-color LED light. The buzzer is used to generate an audible alarm when the power supply is abnormal. The dual-color LED light displays green when the power supply is normal and switches to red when the power supply is abnormal.

[0050] In this solution, when the external power supply to the equipment is disconnected, the internal lithium battery of the power supply abnormality alarm device will power the device after detecting the abnormality. At the same time, the device will activate the sound and light alarms. The 4G module will send information such as the location of the power supply abnormality to the mobile phone of the on-duty personnel by sending text messages and answering phone calls. This will enable the on-duty personnel to obtain the power supply abnormality information in a timely manner and avoid the problem that the equipment will be out of power for a long time due to the power supply abnormality and the staff will not be able to detect it.

[0051] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
