[0040] In order to enable those skilled in the art to better understand the solution of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of the present invention are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0042] The objective of the present invention is to develop a voice prompt system that is deeply bound to the existing coke oven equipment system, is quick and simple to debug, and has a low cost. Figure 1 This is the overall design scheme of the system of the present invention. This scheme takes the PLC of a single vehicle as the control core, and the external audio and the upper industrial control computer equipment are both connected to the PLC and controlled by the PLC control module. Among them, the content of the control is to generate a logic variable according to the trigger condition, the logic variable is mapped to the industrial control computer to generate a WINCC variable, the WINCC variable activates the MP3 startup code of the industrial control computer to play the MP3 audio file, and finally the final output state is expressed by the WINCC screen.

[0043] Based on this, the present invention provides a voice broadcast system for coke oven vehicle equipment, including:

[0044] A voice file generation module, which is used to convert text into a voice file and store it in the industrial control computer;

[0045] A PLC control module, which is used to generate a logic variable according to the trigger condition to activate the voice broadcast;

[0046] An industrial control computer module, which is used to receive the logic variable of the PLC control module and control the playback of the voice file;

[0047] A hardware connection module, including a USB speaker, which is used to play the voice file.

[0048] When specifically implemented, as a preferred implementation manner of the present invention, the voice file generation module uses voice generation software (such as TTSMaker) to convert text into a voice file and record the file duration. In this embodiment, such as Figure 2As shown, use the speech generation software (TTSMaker PC version) to convert text into recorded speech. Each audio file is a dedicated voice prompt. The figure shows the recording of the "Door Closing Alignment Completed" file. At the same time, record the duration of the recorded voice file for programming needs. Finally, store all the generated voice files on the industrial control computer of the coke oven equipment for use, such as Figure 3 as shown.

[0049] In specific implementation, as a preferred implementation manner of the present invention, the PLC control module activates voice broadcast by establishing a voice playback function block (FC block) and logical variables. In this embodiment, the PLC control module establishes a voice playback FC block and edits logical variables for activating different voices according to trigger conditions, such as Figure 4 (left half part) is the sorted voice activation signal, and the address is DB3.DBX2.0~DB3.DBX3.3, a total of 12 signals. At the same time, establish a voice step sequence variable. In Figure 4 , the current voice step sequence is 1, that is, the first step, and the activation variable is the coking push for alignment (address 2.0). It can be seen that "Pushing Position Alignment" on the right picture turns green.

[0050] In specific implementation, as a preferred implementation manner of the present invention, the industrial control computer module establishes variable mapping through WINCC software and realizes the playback of voice files. In this embodiment, first, the industrial control computer module establishes 12 corresponding variables through WINCC software, and the address is set to be the same as the activation variable in the PLC control module, that is, DB3.DBX2.0~DB3.DBX3.3, so as to complete variable signal mapping, such as Figure 5 . Secondly, create a voice playback page on the industrial control computer screen, such as Figure 6 . Logically connect each display block in the figure with the variables in Figure 5 to realize that when a certain variable in Figure 5 is activated to "1", the corresponding display block in Figure 6 becomes "green" to indicate activation. Finally, the industrial control computer module generates an instruction for MP3 voice playback through WINCC software, such as Figure 7 . The instruction for MP3 voice playback includes "Initialize MP3 decoder", "Set SDL audio device parameters", "Open audio device", "Start audio playback", "Read and decode MP3 data", "Clean up resources". The effect is to play the corresponding voice file according to the mapped variables received in WINCC, realizing voice broadcast synchronized with the device actions.

[0051] In specific implementation, as a preferred implementation manner of the present invention, the hardware connection module includes a USB speaker connected to the USB interface of the industrial control computer. In this embodiment, as Figure 8 ​As shown, after completing the preparation of the above voice file and logical variables, connect the USB speaker to the USB interface of the industrial control computer to receive the sound signal and play the voice.
