[0002] Buses are a common means of transportation in our daily lives, offering numerous advantages such as convenience, speed, low carbon emissions, and environmental friendliness. Currently, most buses are equipped with automatic stop announcement systems. Compared to traditional manual announcement systems, these systems reduce the burden on drivers and improve operational efficiency. However, most current automatic stop announcement systems still rely on manually controlled announcement systems, requiring manual control for stop sign recognition and voice announcements for entry and exit points. This not only increases driver workload but also creates safety risks. Currently, the most prominent automatic stop announcement technology utilizes GPS technology. Automatic bus stop announcement systems typically rely on the Global Positioning System (GPS) to obtain real-time location information for buses. This information is combined with electronic map data, and onboard equipment calculates the bus's current position. The system then automatically announces the name of the upcoming stop based on pre-set bus route data. While these systems are comprehensive and offer stable output, they are costly, particularly for small and medium-sized cities. Therefore, there is an urgent need to develop a comprehensive, cost-effective, and readily accessible automatic stop announcement system. Summary of the Invention

[0035] Example 1

[0036] Additional aspects and advantages of the embodiments of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the embodiments of the present invention.

[0037] Combine Figure 1 and Figure 2 , an embodiment of the present invention provides a bus automatic stop announcement control system, comprising:

[0038] The main control module 04, the wireless radio frequency module 02, the liquid crystal display module 06, the voice broadcast module 07 and the power supply module 05 are electrically connected to the main control module 04 respectively; wherein,

[0039] The main control module 04 is used to obtain and process the entry and exit information of the bus, and to control the voice broadcast module 07 to play the voice data and display it synchronously on the liquid crystal display module 06.

[0040] The wireless radio frequency module 02 is used to collect the entry and exit information of the bus and transmit it to the main control module 01.

[0041] The liquid crystal display module 06 is used to display the played voice data as well as time and temperature data.

[0042] The voice broadcast module 07 is used to obtain and play voice data, where the voice data is real-time bus stop information data.

[0043] The power module 05 is used to convert the power supply voltage into the voltage required by the microcontroller.

[0044] The main control module 04 of the present invention utilizes an 8-bit CMOS single-chip microcomputer, the AT89C51. The AT89C51 single-chip microcomputer minimum system serves as the primary control circuit to control the audio playback of the voice broadcast module 07 and the synchronous display of the liquid crystal display module 06. The operating principle of the present invention is that the wireless radio frequency module 02 collects bus entry and exit information and transmits it to the main control module 04 for processing. The voice broadcast module 07 is used to acquire and play voice data, while the liquid crystal display module 06 is used to synchronously display the broadcast content of the voice broadcast module 07. Considering that the power supply voltage of the single-chip microcomputer is different from that of the bus, the operating voltage of the single-chip microcomputer AT89C51 of the present invention is 5V, so a power supply module 05 is required to perform voltage conversion.

[0045] Specifically, the system also includes a crystal oscillator circuit 01 and a clock module 03, each electrically connected to a main control module 04. Clock module 03 is used to time bus entry and exit times, ensuring accurate bus entry and exit announcements. Crystal oscillator circuit 01 provides precise clock signals for the circuits, ensuring that operations such as data processing, instruction execution, and peripheral control proceed according to predetermined timings.

[0046] Specifically, the system also includes a speaker 09 and a power amplifier 08. The input of the power amplifier 08 is connected to the output of the voice broadcast module 07, and the output of the power amplifier 08 is connected to the input of the speaker 09. The power amplifier 08 amplifies the low-power signal received from the audio source to a sufficient power level to drive the speaker 09 to produce a sufficiently loud sound. The power amplifier 08 increases the signal's power output by increasing the voltage or current, ensuring that the speaker 09 can function properly and produce the desired sound effects.

[0047] Specifically, the system also includes a push button switch 10, which is respectively connected to the LCD display module 06 and the voice broadcast module 07. By setting the push button switch 10, manual bus stop announcement can be realized. When the bus passes the bus stop, by pressing the push button switch 10, the voice broadcast module 07 is controlled to play the voice data, and the LCD display module 06 is controlled to synchronously display the played voice data.

[0048] Specifically, the wireless RF module 02 includes a receiving module 021 and a codec integrated circuit 022, and the receiving module 021 is electrically connected to the codec integrated circuit 022. The receiving module 021 is used to receive data transmitted by wireless signals. The receiving module 021 works in conjunction with the codec integrated circuit 022 to decode the received signal into data that can be recognized by the circuit.

[0049] Specifically, voice broadcast module 07 uses a WT588D voice chip, and power amplifier 08 uses an LM386 chip. The WT588D voice chip is used for voice broadcast, while the LM386 chip amplifies the audio signal transmitted by the WT588D voice chip. The WT588D voice chip's reset port is connected to pin P3.7 of main control module 04, controlling whether the WT588D voice chip is enabled. The WT588D voice chip's VSDA port is connected to pin P3.5 of main control module 04 to read the address to be played. The WT588D voice chip's VSCL port is connected to pin P3.3 of main control module 04 to control the broadcast timing. The WT588D voice chip's auto-mute port is connected to ground via a capacitor. The audio signal is transmitted via the WT588D voice chip's output port, audout, to the filter circuit for filtering, then to the LM386 chip for playback through speaker 09.

[0050] Specifically, the liquid crystal display module 06 uses an LCD12864 chip, which can display 128×64 dot matrix text and graphics. The LCD12864 chip has a port that can be connected to the CPU for easy testing. At the same time, the LCD12864 chip also has the function of displaying and moving the cursor.

[0051] Example 2

[0052] Based on the above system, the embodiment of the present invention also provides a method for controlling automatic bus stop announcements. Figure 3 Shown, including:

[0053] Initialize the system and select the bus stop announcement mode, which includes automatic and manual modes. After the system is turned on, it enters the initialization phase, during which time and temperature information are displayed on the screen. After the system is turned on, you can select the bus stop announcement mode, which includes automatic and manual modes. You can choose one of these modes according to your actual needs.

[0054] In the automatic station announcement mode, the wireless RF module is enabled. Every time a bus passes a bus stop, the wireless RF module automatically collects the bus's entry and exit information and transmits it to the main control module for processing. The main control module controls the voice broadcast module to play the voice data and display it synchronously on the LCD display module.

[0055] In the manual broadcast mode, during the period when no bus stops are announced, the LCD display module displays time and temperature data. When the bus passes by the bus stop, the voice broadcast module is controlled by manually pressing the button switch to play the voice data, and the LCD display module is controlled to synchronously display the played voice data, where the voice data is real-time bus stop information data.

[0056] In summary, the automatic bus stop announcement control system and control method provided by the present invention, compared with traditional bus stop announcement devices, which require manual control for bus stop sign recognition and entry and exit voice broadcasts, automatically recognize bus stops by setting a wireless radio frequency module and control entry and exit voice broadcasts, replacing the traditional manual station announcement process, reducing the burden on drivers and improving the operating efficiency of buses. At the same time, the present invention is low-cost and easy to popularize.
