Description
Technical field
The present invention relates to Airshower chamber control system field, particularly relate to a kind of Airshower chamber speech prompting system based on multifunctional storage card.
Background technology
Airshower chamber is requisite clean support equipment in modern industry clean room, and it can remove the dust on people and thing surface, again the clean area of Airshower chamber both sides and non-clean area has been played to the effect of buffering with isolation simultaneously.This equipment is widely used in the fields such as food, medicine, bioengineering and precise electronic.
Airshower chamber product has following two kinds of situations at present:
1) most of Airshower chamber, be not with sound prompt function, the personnel of use equipment are not in the situation that understand or be not suitable with the workflow of Airshower chamber, often there is violating the operation of flow process, cause when door locking and open the door by force, cause electromagnetic lock to damage, or be locked in the abnormal conditions such as in a dilemma in Airshower chamber and occur.As increased " voice system ", can provide in time corresponding voice message from instructing status surveillance two aspects of operation and door, supervise user to observe workflow, standard operation;
2) minority has realized the Airshower chamber of sound prompt function, based on speech chip, realizes.Speech chip, only built-in a small amount of storage space, is generally 1Mbit--4Mbit, 40-160 second storage time, can be by controlling by key control or MCU, the direct integrated circuit (IC) chip of sounding.Its defect is, the length that voice are deposited determined by audio sample rate and chip internal (or plug-in) ROM space, and the size of audio sample rate directly affects the tonequality of audio frequency output, and audio sample rate is higher, tonequality is better, but need to take more storage space.The cost of chip is also because the increase of storage space has obvious rise.The content of speech chip is changed in addition, must pass through the built-in ROM of burning speech chip again, often need controller to return and generate producer's burning again, or generate producer with the replication tool of upper neat cover to field upgrade, thereby cause changing efficiency slowly and the maintenance cost of wholesale.
In traditional scheme, a small amount of storage space that voice storage module is carried by speech chip inside is realized, and price is high, and storage space is little, changes upgrading trouble; Speech production module is processed by speech chip, and processing power is limited.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of Airshower chamber speech prompting system based on multifunctional storage card, by adopting voice storage module to be realized by multifunctional storage card, low price, cost is low, replacing is convenient, upgrading is convenient, storage space is large, on the Airshower chamber speech prompting system based on multifunctional storage card universal, has market outlook widely.
For solving the problems of the technologies described above, the invention provides a kind of Airshower chamber speech prompting system based on multifunctional storage card, comprise: processor unit, speech trigger module, voice storage module, speech production module and voice playing module, described speech trigger module electrical connection also passes to described processor unit by trigger pip, described voice storage module is electrically connected described processor unit, described speech production module is electrically connected the output terminal of described processor unit, described voice playing module is electrically connected the output terminal of described speech production module, described voice storage module is multifunctional storage card, described processor unit reads the voice content of storing in described voice storage module according to trigger pip, after voice content being passed to described speech production module again, by described voice playing module, broadcast.
In a preferred embodiment of the present invention, described speech production module comprises operational amplifier.
In a preferred embodiment of the present invention, described voice playing module is loudspeaker.
In a preferred embodiment of the present invention, described multifunctional storage card comprises SD card, CF card, TF card, USB flash disk, portable hard drive etc.
The invention has the beneficial effects as follows: the Airshower chamber speech prompting system that the present invention is based on multifunctional storage card has been realized and not changed under the prerequisite of single-chip microcomputer source program, change quickly and easily the content in storage card, there is the advantages such as novel structure, volume be small and exquisite, easy to carry, easy to use, on the Airshower chamber speech prompting system based on multifunctional storage card universal, have market outlook widely.
