Technical field
The utility model relates to a kind of voice station reporting instrument, especially relates to a kind of voice station reporting instrument applicable to elevator, jacking equipment.
Background technology
At present, the technology of the voice station reporting instrument employing of elevator, jacking equipment use is as follows:
1) adopts the speech chip technology: speech chip is changed, is burnt to voice document with special tool.Be placed in the circuit, to its addressing, the speech data of corresponding address unit can play back automatically by a common MCU.The program firmware need not be concerned about coding-decoding operation and the file read-write operation of voice, is easier to realize from the technical standpoint ratio.But such voice station reporting instrument exists, and voice capacity is limited, speech quality is relatively poor, defective such as new speech, firmware inconvenience more; Especially, when voice more for a long time, come the extended voice capacity by increasing the chip number, cost is higher.
2) adopt senior operation system technology such as linux: the minimal hardware system that adopts High Performance MCU to form adds audio converter, power amplifier, CANbus controller.Taking full advantage of senior operating system such as linux realizes sound broadcast, upgrades voice document, upgrades functions such as firmware and man-machine interaction the support of file system, multimedia.The software and hardware system complexity of such voice station reporting instrument generally needs the circuit card more than 4 layers, and High Performance MCU is normally BGA encapsulation then, production technology, welding gear are had relatively high expectations, so that cost is very high.In addition, owing to adopt high level operating system, make program start and sluggish.
3) adopt the multi-chip combination technique: adopt common MCU+USB HOST control chip+chip of speech decoder+CAN controller.Be characterized in utilizing chip of speech decoder to finish the decoding action, i.e. hardware decoding can reduce the operational performance requirement to MCU.This type of voice station reporting instrument exists that member is many, cost is high, take problems such as board area is bigger.
The utility model content
At the problems referred to above and the defective that prior art exists, the purpose of this utility model provide a kind of have simple in structure, memory capacity is big, tonequality good, the voice station reporting instrument of low cost and other advantages.
For realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is as follows:
A kind of voice station reporting instrument comprises: MCU, memory device and audio digital to analog converter is characterized in that: described MCU is built-in with CAN controller and USB HOST controller, and described memory device is the TF card.
As a kind of preferred version, described voice station reporting instrument also is provided with the CANbus interface.
As further preferred version, described CANbus interface is isolated form CANbus interface.
As a kind of preferred version, described voice station reporting instrument also is provided with USB interface.
As a kind of preferred version, described TF card is equipped with the FAT file system.
As further preferred version, described voice station reporting instrument also is provided with volume and regulates button.
As further preferred version, described voice station reporting instrument also is provided with status indicator lamp.
As further preferred version, described voice station reporting instrument also is provided with audio-frequency power amplifier.
As preferred version further, described audio-frequency power amplifier is the monophonic audio power amplifier.
Compared with prior art, the utlity model has following beneficial effect:
The voice station reporting instrument that the utility model provides, employing is built-in with the multi-functional economical MCU of CAN controller and USB HOST controller, can when operation, decode to voice document, and do not need audio file to be encoded in advance and be burnt in the speech chip, have advantages such as tonequality is good, running velocity is fast; And adopt the TF card as memory device, have that memory capacity is big, expansion is convenient, take that volume is little, cost low and advantage such as applicability is strong; In a word, the voice station reporting instrument that the utility model provides, have simple in structure, memory capacity is big, tonequality good, low cost and other advantages, has broad applicability.
Description of drawings
Fig. 1 is the structural representation of a kind of voice station reporting instrument of providing of the utility model.
Specific implementation method
Below in conjunction with accompanying drawing the technical solution of the utility model is done further and to be elaborated:
Embodiment
As shown in Figure 1: a kind of voice station reporting instrument that present embodiment provides comprises: MCU, memory device, audio digital to analog converter and CANbus interface is characterized in that: described MCU is built-in with CAN controller and USB HOST controller, and described memory device is the TF card; MCU receives the instruction of calling out the stops through the CANbus interface, reads in speech data from the TF card then, by built-in USB HOST controller speech data is decoded, and exports decoded result to described audio frequency digiverter and convert the voice of calling out the stops to.
Described CANbus interface is preferably isolated form CANbus interface, can increase independence and obstacle overcome ability.
As a kind of preferred version, described voice station reporting instrument also is provided with USB interface, can directly communicate by letter with other USB device with convenient described voice station reporting instrument, directly finish firmware upgrade and data exchange, and no longer need to operate by other computing machine renewal and the upgrading of increase, deletion and other software of voice document.
As a kind of preferred version, described TF card is equipped with the FAT file system, because present most of digital product is all supported the FAT file system, the TF card is easy to again by interconnecting device and other mobile device communication, and this can increase commonality and the ease for use of the utility model voice station reporting instrument greatly.In addition, the TF card has also that memory capacity is big, expansion is convenient, take advantages such as volume is little, with low cost.
