Background art:
in the design work of electronic circuits, a requirement that the equipment has voice prompt output is often met. Such voice prompt functionality is required, for example, in the power cable tunnel monitoring devices that we have now developed.
The installation position of the power cable tunnel monitoring equipment is generally inside a tunnel, and the power cable tunnel monitoring equipment and a sensor are required to be installed in a close range so as to ensure the accuracy of data acquisition. Moreover, the environment of the tunnel is generally relatively humid, and toxic and harmful gases are generated. Based on the situation, all tunnel equipment needs to be designed to be moisture-proof and explosion-proof. Under the condition, when the tunnel equipment is subjected to field troubleshooting, the fault point of the equipment is not well determined, only two conditions can be checked, one is to check the running state of the equipment through a remote server end of a worker and confirm through internal telephone contact (other communication equipment in the tunnel does not have signals under the common condition), and the other is to determine on the field through visual hardware or query and determine through computer debugging software. Both approaches have drawbacks, the first being that other personnel must be present to coordinate the inspection, and that it is substantially impossible to ensure that there is an intranet phone near each device. The second approach has the disadvantage that each device is inspected either visually or by field computer software, and the work involved in field troubleshooting and troubleshooting is too extensive and time consuming. Therefore, if the field device can automatically broadcast the operation state and the fault point by voice, the workload of troubleshooting is greatly reduced, and the working efficiency of fault determination is improved. Thereby quickly removing the fault.
For the foregoing reasons, there is a need for a voice conversion module that is simple in structure, convenient to plug in, and compatible with multiple devices. If the equipment is required to be installed, if the equipment is not required to be installed, the normal work of the equipment is not influenced regardless of installation or not.
The utility model has the following contents:
the utility model discloses the technical problem that will solve is: overcome prior art's not enough, form plug-and-play's voice conversion module through communication interface treater and megaphone, directly convert text information into pronunciation and play out, easy operation, convenient to use, the multipurpose voice conversion module that people of being convenient for overhauld equipment and troubleshooting.
The technical scheme of the utility model is that: a multipurpose voice conversion module comprises a power amplifier, a processor and a loudspeaker, and is characterized in that: the processor is connected with the communication interface, processes the information acquired from the communication interface, sends the information to the TTS module, and finally plays voice through the power amplifier and the loudspeaker;

Further, the loudspeaker adopts a common horn with the volume lower than 3W.
The utility model has the advantages that:
1. the utility model discloses a communication interface treater and megaphone form plug-and-play's voice conversion module, directly convert text information into pronunciation and play out, easy operation, convenient to use, and the people of being convenient for overhaul equipment and troubleshooting.
2. The utility model discloses the host computer utilizes the intercommunication mode of existing equipment, exports the information for the module through RS232 or RS485 interface, and after the treater received these text messages, add information head and special mark to these information segmentations, constitute the data package that accords with the TTS chip to send it to the TTS chip, then generate voice analog signal, amplify analog signal through power amplifier circuit after that, play out the pronunciation through the speaker at last.
3. The utility model discloses there are two kinds of communication interface modes, can realize multiple signal input, the compatibility is higher, is fit for different equipment, and simultaneously, amplifier circuit and TTS chip adopt different chips to carry out information processing, and the redundancy is high.
