When the dock control system generates task instructions, the operational instruction audio playback system will automatically call the program to read the instruction content. Based on different task categories, it will generate voice broadcast content. The instruction audio playback system will then call the speech synthesis technology module to enable the wireless handheld terminal to play the voice broadcast aloud. The system will convert the already categorized and generated voice broadcast content into external audio, achieving the effect of audible prompts.

[0075] By using an audio-visual instruction system, the information acquisition mode can be transformed from passive reading to proactive prompting, ensuring that instructions and task information are delivered to operators in a timely manner. This also avoids operators repeatedly checking their handheld PDA terminals to confirm task information, thereby improving the timeliness, accuracy, and security of tasks.

[0076] First, the wireless handheld terminals installed on internal container trucks, tire cranes, hazardous materials handling areas, and refrigerated container handling areas are upgraded to include an audio-visual instruction system. Then, users log in to the system using their existing account and password to access the task display interface. Based on their job responsibilities, users select the corresponding task type; for example, internal container truck drivers select the container truck task interface. Once in the corresponding task display interface, no further action is required; the system automatically transmits the audio-visual instructions after receiving the task.

[0077] After the system was put into actual production operations, it achieved the following results:

[0078] 1. Proactively, promptly, and accurately provide production task information to operators, achieving a 100% task confirmation rate. This allows operators to obtain task information in a timely manner even during busy work periods, enabling them to prepare for tasks in advance and ensuring operational continuity.

[0079] 2. Operators can avoid frequently checking the wireless handheld terminal screen and operating interface to confirm system production instructions during operations. This is especially beneficial for truck drivers and tire crane operators, preventing them from stopping to confirm instructions while operating equipment, or making unauthorized confirmations, thus improving production safety. The number of on-site production safety issues caused by handheld terminal confirmations is reduced to zero.

[0080] 3. The operation instruction audible external transmission system has universality, and has the characteristics of being reproducible and extendable.

[0081] 4. The loudspeaker is added, but is waterproof, adopts an arc cover plate structure and a through hole, and a waterproof film is arranged under the cover plate, so that the sound transmission direction is not limited to the rear of the shell, can be transmitted to the side, the external sound of the handheld terminal can be effectively transmitted to the operation personnel, the terminal does not need to be turned over to improve the volume, and the waterproof treatment makes the handheld terminal suitable for various waterproof places, especially operation places such as wharfs and ports.

[0082] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
