[0024] Referring to Figure 1 , a preferred embodiment of the present utility model, a power control semiconductor module, the semiconductor module includes a power module 1, a voltage regulation module 2, an automatic short - circuit module 5, a voltage transformer 3, a voltage transformer monitoring module 7, a control circuit 4, a background alarm 14, and a semiconductor 6; the voltage transformer monitoring module 7 includes a voltage transformer monitoring unit 8, a temperature monitoring unit 9, a humidity monitoring unit 10, and a voice alarm unit 11;

[0027] Specifically, the magnitude of the output circuit voltage is detected by the voltage transformer 3 and the voltage magnitude is fed back to the control circuit 4. When the voltage value received by the control circuit 4 is slightly greater than or less than the preset value (a voltage value is preset by the TMS320F2812 data processor), the voltage regulation module 2 is controlled by the control circuit 4 to adjust the voltage upward or downward, thereby stabilizing the voltage. When the voltage value received by the control circuit 4 is significantly greater than the preset value, the resettable fuse in the automatic circuit breaker module 5 is melted by the control circuit 4, thereby cutting off the output circuit to prevent the high voltage from burning out the power supply or working components. At the same time, the control circuit 4 also supplies power to the background alarm 14 to make the background alarm 14 issue an alarm to prompt people that the voltage is abnormal.

[0028] In this embodiment, the present utility model is further provided with a voltage transformer monitoring module 7 for detecting the working state of the voltage transformer 3.

[0029] Further, the voltage transformer monitoring unit 8 is connected to the control circuit 4 for realizing the monitoring of the secondary side voltage of the voltage transformer 3; the voltage transformer monitoring unit 8 includes a voltage converter, a low-pass filter, a polarity converter, and an analog-to-digital converter.

[0030] Specifically, the voltage converter is installed on the secondary side of the voltage transformer 3. After the voltage on the secondary side of the voltage transformer 3 is transformed, it is processed by a low-pass filter, a polarity converter, and an analog-to-digital converter to obtain a signal that can be processed by the TMS320F2812 processor in the control circuit 4.

[0035] Furthermore, the voice alarm unit 11 is connected to the control circuit 4 and is used to play and alarm the current operating state and fault conditions of the voltage transformer 3 through voice; the voice alarm unit includes: a voice alarm chip and a speaker.

[0036] Specifically, the voice alarm chip is connected to the control circuit 4, and the voice alarm chip is connected to the speaker to complete the voice playback and alarm of the current operating state and fault conditions of the voltage transformer 3.

[0037] In this embodiment, the semiconductor module further includes a GSM module 12 for communication. The GSM module 12 is bidirectionally communicatively connected to the control circuit 4, and the GSM module 14 interacts with the mobile phone 13.

[0038] Specifically, the control circuit 4 sends the obtained operating data to the authorized mobile phone 13 through the network via the GSM module 14. Thus, the staff can remotely receive the information sent by the GSM module 12 through the authorized mobile phone 13, so as to timely grasp the working state of the present utility model, and it is also beneficial for the staff to make timely and correct responses to possible emergencies.

[0039] Working principle of the utility model: During use, the magnitude of the output circuit voltage is detected by the voltage transformer 3, and the magnitude of the voltage is fed back to the control circuit 4. When the voltage value received by the control circuit 4 is slightly greater than or less than the preset value, the voltage adjustment module 2 is controlled by the control circuit 4 to adjust the voltage upward or downward, thereby stabilizing the voltage. When the voltage value received by the control circuit 4 is significantly greater than the preset value, the self-resetting fuse in the automatic circuit breaker module 5 is blown by the control circuit 4, thereby cutting off the output circuit to prevent the power supply or working components from being burned by high voltage. At the same time, the control circuit 4 also supplies power to the background alarm 14, causing the background alarm 14 to issue an alarm to prompt people that the voltage is abnormal; and while the voltage transformer 3 detects the magnitude of the output circuit voltage, the working state of the voltage transformer 3 is monitored by the voltage transformer monitoring module 7: Among them, the voltage transformer monitoring unit 8 monitors the secondary-side voltage of the voltage transformer 3 in real time, and the humidity monitoring unit 10 monitors the humidity of the operating environment of the voltage transformer 3 in real time; the temperature monitoring unit 9 monitors the temperature on the incoming bus of the voltage transformer 3, the secondary-side outgoing line joint of the voltage transformer 3, and the voltage transformer 3; the voice alarm unit 11 plays and alarms the current operating state and fault conditions of the voltage transformer 3 through voice; the control circuit 4 transmits the operating data obtained by the voltage transformer monitoring module 7 to the authorized mobile phone 13 through the GSM module 12 via the network. Thus, the staff can remotely receive the information sent by the GSM module 12 through the authorized mobile phone 13, so as to timely master the working state of the utility model, and it is also beneficial for the staff to make timely and correct responses to possible emergencies.

[0040] The utility model can detect the magnitude of the power supply output voltage, and stabilize the magnitude of the power supply output voltage through the voltage adjustment module 2. When the voltage is too high, the circuit can be cut off through the self-resetting fuse to prevent the power supply or working components from being burned by high voltage, and an alarm can be issued in time through the background alarm 14 to remind people that the voltage is abnormal.

[0041] The utility model realizes the monitoring of the operating state of the voltage transformer 3 through the voltage transformer monitoring module 7, can collect the operating parameters of the voltage transformer 3 in real time, is convenient for viewing the state of the voltage transformer 3 and operating the monitoring system, gives a voice alarm for the fault information of the voltage transformer 3, and wirelessly sends the fault alarm information to the staff for timely processing, ensuring the normal operation of the voltage transformer 3 and improving the stability of the utility model.

[0042] On the premise of no conflict, those skilled in the art can freely combine and superimpose the above additional technical features.
