Therefore, improvements are needed. Utility Model Content

[0004] This utility model is achieved through the following technical solution:

The MCU voice control circuit is electrically connected to the voice broadcasting circuit. The power supply circuit is electrically connected to the MCU voice control circuit and the voice broadcasting circuit.
[0006] The main control circuit includes a main control chip, which receives signals input from the measurement circuit. The main control chip has pins 36, 37, and 38. One side of the MCU voice control circuit is electrically connected to pins 36, 37, and 38 of the main control chip, respectively, for transmitting the voice information to be played. The other side of the MCU voice control circuit has pins 5, 6, and 7.

[0028] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.
[0029] Please refer to Figures 1-9 This utility model proposes a delayed broadcast voice circuit, including a main control circuit 1, an MCU voice control circuit 2, a measurement circuit 3, a voice broadcast circuit 4, a display driver circuit 5, and a power supply circuit 6. The main control circuit 1 is electrically connected to the MCU voice control circuit 2, the measurement circuit 3, the display driver circuit 5, and the power supply circuit 6 respectively. The MCU voice control circuit 2 is electrically connected to the voice broadcast circuit 4. The power supply circuit 6 is electrically connected to the MCU voice control circuit 2 and the voice broadcast circuit 4 respectively.
[0030] The main control circuit 1 includes a main control chip 11, which is an integrated circuit chip used to issue corresponding operation instructions to the MCU voice control circuit 2, the measurement circuit 3, the display driver circuit 5, and the power supply circuit 6. At the same time, the main control chip 11 is used to receive signals input from the measurement circuit 3. The main control chip 11 has pins 36, 37, and 38. One side of the MCU voice control circuit 2 is electrically connected to pins 36, 37, and 38 of the main control chip 11 to transmit the voice information to be played. The other side of the MCU voice control circuit 2 has pins 5, 6, and 7. One side of the voice broadcasting circuit 4 is electrically connected to pins 5, 6, and 7 of the MCU voice control circuit 2 to play the voice information.
[0031] In this embodiment, after the main control circuit 1 receives the signal from the measurement circuit 3, it first transmits the measured data information to the MCU voice control circuit 2 for relay. Then, after the signal from the measurement circuit 3 stops changing, the MCU voice control circuit 2 transmits the voice information to the voice broadcasting circuit 4 for broadcasting. When the measurement circuit 3 has no input signal to the main control circuit 1, the timing circuit in the main control circuit 1 is reset to 0, the data from the MCU voice control circuit 2 is not sent to the voice broadcasting circuit 4, and the voice broadcasting circuit 4 does not work. When the measurement circuit 3 has a signal, the timing circuit in the main control circuit 1 starts to accumulate the time. When the accumulated time reaches the delay setting T, the main control circuit 1 sends the measurement result to the MCU voice control circuit 2, and the MCU voice control circuit 2 sends the voice information to the voice broadcasting circuit 4 to broadcast the measurement result and records the broadcast data. The recorded data is displayed by the display driving circuit 5. The delay time T is between 0.5 seconds and 60 seconds. In use, the delay time T can be adjusted according to different measurement signals. When the measurement result of the measurement circuit 3 is equal to the recorded broadcast data, the timing circuit in the main control circuit 1 is cleared to 0. When the measurement result of the measurement circuit 3 is not equal to the recorded broadcast data, the timing circuit accumulates the time. When the accumulated time reaches the delay setting T, it repeats step 2. If there is no input signal, it returns to step 1. The advantage of its delayed broadcast is that the timing starts when a new signal is detected, and the broadcast is only executed when the set delay is reached and the measurement result changes. This strategy effectively avoids the continuous repetition of the same result when the data is stable, and also reduces the problem of excessively frequent broadcasts when the data changes frequently. This utility model enhances the user experience and ensures the timeliness and accuracy of information transmission by intelligently adjusting the broadcast logic.
