[0031] like Figure 1 and Figure 2 As shown, an embodiment of the present invention discloses a 4G voice prompt device, comprising a cellular communication main control module with 4G communication capabilities, a traffic card control module, a power amplifier module, and a power supply module. The power supply module is connected to the cellular communication main control module and the power amplifier module, respectively, and the traffic card control module is connected to the cellular communication main control module. The cellular communication main control module is a circuit board module with 4G communication capabilities. In this embodiment, the L610-CN main control module is preferably used. Other control modules capable of cellular communication are also within the scope of protection of this application. The L610-CN main control module is powered by a TD1583 step-down circuit to provide a stable 3.8V voltage. It is connected to the S336 satellite positioning module, TPA3110 power amplifier module, human body sensing module, and flashing light control module in the circuit, enabling stable data and command transmission. The L610-CN main control module is connected to various components of the circuit, detecting the status of each circuit and processing information obtained by the circuit, responsible for controlling the operation of the circuit system. The device itself and monitored data are uploaded to the Internet of Things platform via 4G communication technology. Leveraging the cloud platform's powerful application capabilities, devices can be more comprehensively managed and monitored. Users can control devices through data commands from the cloud platform, achieving a more natural and intuitive interaction. This allows for multiple device connections, overcoming data synchronization challenges, and enabling devices to work with multiple devices. Through 4G IoT communication technology, users can reduce their reliance on physical buttons, improving operational convenience. Real-time data feedback and prompts from devices can also enhance interaction between users and devices, making operation more user-friendly and intelligent.

[0032] like Figure 7As shown, the device also includes a human body sensing module, which consists of a pyroelectric sensor, resistor R20, and transistor Q3. Pin 1 of the pyroelectric sensor is grounded, pin 3 is connected to a 5V voltage, and pin 2 is connected to the base of transistor Q3 via resistor R20. The collector of the transistor is connected to a 1.8V voltage, and the emitter is grounded. Specifically, the pyroelectric sensor is powered by a 78L05S step-down circuit, providing a stable 5V voltage. When it senses a person, it sends a data instruction to the main control module L610-CN, which then sends an operating instruction to the power amplifier module and flashing light module for audio and visual notification. A controllable and adjustable switch allows the sensing distance to be adjusted between 3 and 12 meters.

[0033] like Figure 8 As shown, the device also includes a flash control module, which includes a flash, field-effect transistor Q4, resistor R26, and transistor Q8. Pin 1 of the flash is grounded, pin 2 is connected to the drain of field-effect transistor Q4, the source of field-effect transistor Q4 is connected to a 3.3V voltage, and the gate is connected to the collector of transistor Q8. The base of transistor Q8 is connected to the cellular communication main control module via resistor R26, and the emitter is grounded. The flash control module uses a red and blue flashing device, powered by a stable 3.3V voltage provided by the SSP7603P33 voltage regulator circuit. The main control module L610-CN controls its power supply, providing both audible and visual notifications.

[0034] like Figure 4 As shown, it also includes a satellite positioning module, which is connected to the cellular communication main control module and the power supply module respectively.

[0035] like Figure 5 As shown, the flow card control module includes a built-in flow card control circuit and an external flow card control circuit.

[0036] In this embodiment, the power amplifier module preferably uses an upgraded and optimized TPA3110 power amplifier module, powered by a 5V voltage processed by a 78L05S step-down circuit to ensure a stable power supply. It also receives function commands and audio input from the main control module L610-CN. The input audio passes through the TPA3110 power amplifier module to achieve a stable, noise-free 30W audio output. The entire circuit also performs audio distortion and noise reduction processing, ensuring stable, noise-free, high-quality audio output.

[0037] like Figure 3As shown, the power supply module includes a solar charging circuit, a power supply, and first and second processing circuits. The solar charging circuit is connected to the power supply, and the first and second processing circuits are respectively connected to the power supply. The power amplifier module and human body sensing module are connected to the first processing circuit, and the main control module, satellite positioning module, and flash control module are connected to the second processing circuit. In this embodiment, the solar charging circuit preferably uses CN3763 as the core. CN3763 works with a small number of peripheral components to perform PWM step-down on the power input from the solar panel. It has two charging modes: constant current charging and constant voltage charging. After the battery voltage reaches a certain level, CN3763 enters the constant current charging stage. At this stage, the charging current is set by an external resistor to ensure that the battery is charged at a stable current. As the battery voltage increases, CN3763 gradually reduces the charging current. When the battery voltage reaches the set constant voltage charging voltage of 12.6V, it enters the constant voltage charging stage. During this stage, the charging current gradually decreases until it drops to 16% of the constant current charging current, at which point charging is considered complete. By using more stable and precise components, charging is more stable, and PMOS tubes are used instead of traditional diodes to reduce heat generation during charging. At the same time, the L610-CN main control module is used to add a voltage and current detection function to better control the working efficiency of the CN3763 chip.

[0038] In this embodiment, the first processing circuit preferably includes a 5V stabilizing step-down circuit. The 5V stabilizing step-down circuit uses a 78L05S step-down circuit, which processes the voltage supplied by the battery and outputs a 5V voltage output to power and maintain the operation of the TPA3110 power amplifier module and the human body sensing function module.

[0039] The second processing circuit includes a 3.8V stabilization and step-down circuit and a 3.3V stabilization circuit. The 3.8V stabilization and step-down circuit is configured as a TD1583 step-down circuit. Current passes through the TD1583 step-down circuit, which steps down the battery voltage, stabilizing it to 3.8V before outputting it to the back-end functional modules for precise and stable power supply. This provides a stable operating voltage to the main control module L610-CN and to the SSP7603P33 voltage stabilization circuit module. Appropriate adjustment of the circuit's device parameters makes the entire circuit more stable, reduces deviations, and enables a stable 3.8V output. The 3.3V stabilization circuit uses the SSP7603P33 voltage stabilization circuit. The 3.8V voltage processed by the TD1583 step-down circuit is then subjected to the SSP7603P33 voltage stabilization process, stabilized to 3.3V, and then output 3.3V to the S336 satellite positioning module and flash control module. The main control module L610-CN detects the input and output voltage values ​​of the SSP7603P33 voltage regulator circuit in real time to adjust the parameter ratio of the device in real time to control it to stably output a 3.3V voltage.

Users can view the coordinate information on their mobile phones and use the map to arrive at the installation site in a timely and accurate manner to carry out on-site maintenance.

[0043] 3. Equipped with high-efficiency solar panels, it can convert the light energy collected from the on-site environment into electrical energy to supply the equipment in real time. At the same time, the equipment installation and wiring are simple and the installation cost is low. As long as the position is fixed and the power is turned on, it can work, making installation and use more convenient.

[0044] 4. According to the current market demand, sound and light equipment is added to the design, so that the equipment can achieve the function of sound and light warning at the same time. At the same time, it is equipped with cloud platform function, which can achieve real-time voice change and statistical monitoring of the number of playbacks for each device.
