Description
Technical Field
[0001] This utility model relates to the field of intelligent transportation, and in particular to an electronic suitcase card with a voice prompt module. Background Technology
[0002] In the container port operation system, traditional business processes typically rely on paper container pick-up slips as access passes for external trucks (manually driven vehicles). However, this operating model has significant drawbacks: First, paper documents, as physical media, are susceptible to environmental factors such as moisture and soiling, leading to unreadable information and the risk of loss during circulation, directly impacting vehicle throughput. Second, the document printer, as a critical piece of equipment, will cause business processing interruptions if it malfunctions, resulting in vehicle congestion, reduced gate throughput, and other problems, severely affecting the continuity of port operations. Furthermore, managing the driving behavior of external truck drivers within the port area is a pressing challenge. On the one hand, drivers may engage in speeding, driving in the wrong direction, parking outside designated lanes, or making illegal U-turns, threatening traffic order within the port area. On the other hand, due to individual driver behavior differences and the complex working environment, these problems may lead to safety accidents, not only reducing port operational efficiency but also increasing safety hazards. In existing technologies, paper-based document management methods cannot effectively address the aforementioned challenges and lack means to proactively guide or regulate driver behavior. Therefore, how to digitize container pickup cards, obtain real-time container pickup operation information, provide voice prompts, regulate the driving behavior of external container truck drivers, and possess highly usable functions such as easy storage and reusability are technical problems that need to be solved.

[0028] like Figure 1 As shown, an electronic suitcase card with a voice prompt module includes a shell and circuit components. The circuit components include a voice prompt module, a suitcase information display module, and a power module. The voice prompt module includes a wireless receiver module (2), an MP3 module (3), and a speaker module (4). The DATA pin of the wireless receiver module (2) is connected to the IO0 pin of the MP3 module (3) through a first transistor. The SPK+ and SPK- pins of the MP3 module (3) are electrically connected to the speaker module (4). The suitcase information display module includes an Arduino module (5), a screen display module (6), and a screen-off button. The pins of the Arduino module (5) are connected to the screen display module (6) through the SPI protocol. The screen-off button is connected to the RST pin of the Arduino module (5). The power module includes a battery module, a charging module, and a boost module. The input of the boost module is connected to the battery module, and the output is connected to the power supply pins of the voice prompt module and the suitcase information display module, respectively.

The circuits and controls of the wireless receiver module (2), mp3 module (3), speaker module (4), Arduino module and screen display module (6) of this utility model are existing technologies, and the specific circuit structure and working principle will not be described in detail here.
[0029] When the electronic carry-on card is in operation, the boost module of the power module boosts the output voltage of the battery module to 5V to power the voice prompt module and the carry-on information display module; after the wireless receiving module (2) receives the preset radio signal through the antenna, its DATA pin outputs a high-level signal, which is converted into a low-level trigger signal by the transistor and drives the mp3 module (3) to play audio through the speaker module (4); at the same time, the Arduino module (5) receives external carry-on information through the Type-C data interface, and after processing by the USB to TTL converter, transmits the data to the screen display module (6) through the CLK and SDA pins of the SPI protocol to control the screen to display carry-on operation information; the user switches the on / off state of the screen display module (6) by operating the screen off button, and the charging module of the power module replenishes the battery module through the Type-C interface to ensure the continuous operation of the device.

The mp3 module (3) and the speaker module (4) are connected to the speaker module (4) through the first and second capacitors, which are polarized capacitors. The wireless receiving module (2) is connected to the mp3 module (3) through a transistor. After the wireless receiving module (2) recognizes the signal, it outputs a high-level signal through the DATA pin, while the IO0 pin of the mp3 module needs a low-level signal to trigger. Therefore, the high-low level signal conversion is achieved through a transistor. The operating voltage of the mp3 module (3) is 3.3V, which is high-level by default. When it receives a low-level signal converted by the transistor, the mp3 module drives SPK+ and SPK- to work. The connection of CON1, CON2, and CON3 in the circuit is a fixed combination of the mp3 module. The speaker module (4) is connected to the MP3 module through a second and a third capacitor of 220uF to stabilize its working state.

The Arduino module (5) is connected to the 5V power supply terminal of the power supply module through the sixth and seventh capacitors. The RX pin of the Arduino module (5) is connected to the Type-C data interface through a USB to TTL converter. The 3.3V power supply terminal of the screen display module (6) is connected to the power supply module, and the CLK pin of the SPI protocol interface is connected to the Arduino module (5). The computer sends the baggage information to the Arduino module (5). The Arduino module (5) has a built-in USB to TTL converter for receiving the sent data. An LED indicator is connected to the TX pin of the Arduino module (5) to show the signal reception status. The Arduino module (5) is connected to the screen display module (6). The screen display module (6) can be controlled by configuring the pins. The Arduino module (5) has an external screen-off button. The Arduino module (5) is reset by pressing SW1. The screen display module (6) operates at 3.3V and receives information from the Arduino module (5) via the SPI protocol. The CLK pin serves as the clock signal interface, with the clock signal provided by the Arduino module (5). The SDA pin serves as the master device output interface, handling data reception. The RES pin is used for the reset signal, the DC pin distinguishes between commands and data, the CS1 pin enables the device, distinguishing the start and end of signal transmission, and the BLK pin controls the screen's on / off state. In the voice prompt module, the first and second capacitors are 220μF, the third capacitor is 10μF, and the fourth capacitor is 100nF. In the case information display module, the fifth capacitor is 10μF, the sixth capacitor is 10μF, and the seventh capacitor is 100nF.
[0032] like Figure 4 The diagram shows the structure of the outer casing. The casing is a flat rectangular structure with a screen opening (7), an information transmission opening (8), a charging opening (9), and an antenna opening (10) on its surface. The screen opening (7) corresponds to the display area of the screen display module (6), the information transmission opening (8) exposes the Type-C interface of the Arduino module (5), the charging opening (9) exposes the Type-C interface of the charging module, and the antenna opening (10) connects to the SMA antenna interface of the wireless receiving module (2).

[0033] In the use of the carry-on card in this embodiment, after startup, the boost module of the power module boosts the 3.7V output voltage of the battery module to 5V to power the voice prompt module and the carry-on information display module; the wireless receiving module (2) receives radio signals of a specific frequency through the L1 antenna connected to the ANT pin, and its DATA pin outputs a 5V high-level signal, which is inverted by the base-collector circuit of the transistor and converted into a 0V low-level trigger signal input to the IO0 pin of the mp3 module (3) to drive the internal decoding circuit of the mp3 module (3) to work. Its SPK+ and SPK- pins output audio analog signals, which are transmitted to the speaker module (4) to emit sound after being coupled by a 220μF capacitor; at the same time, the external carry-on information is input to the USB interface of the Arduino module (5) through the Type-C data interface, and the 5V logic level is converted to 3.3V through the built-in USB to TTL converter. The TTL level signal is received by the RX pin and parsed into serial data. The Arduino module (5) outputs a 5V clock pulse signal through the CLK pin of the SPI protocol. The SDA pin synchronously transmits 5V logic level serial data to the screen display module (6). The module internally latches the SDA level state according to the rising edge of CLK and parses it into display instructions bit by bit. When the user presses the screen off button, the ground signal pulls down the 5V level of the BLK pin of the Arduino module (5) through the switch, triggering the screen display module (6) to switch between on and off states. The charging module inputs 5V voltage through the Type-C interface, which is converted into a 4.2V constant voltage signal by the charging management chip to charge the battery module. The boost module boosts the battery voltage to 5V in real time to maintain the circuit operation.
