Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the primary structure functional block diagram of the data receiving-transmitting system in the embodiment of the present invention.As shown in Figure 1, this data receiving-transmitting system comprises following three parts:
A unit: be multi-channel data acquisition unit, it comprises N(N >=3) individual transducer, be described for three here, each transducer is integrated with Bluetooth function and (is only citing, be not limited with bluetooth, such as ZIGBEE module also can), for unit B send data; A unit can comprise A1-A3 module, and it is all integrated with transducer and bluetooth module, and the data wireless of transducer collection is sent to unit B by this bluetooth module, and multiple bluetooth module can send data simultaneously.
Unit B: be data transceiving unit, it comprises three modules, is multiple MCU with Bluetooth function (Micro Control Unit, micro-control unit) (B1-B3) respectively, is respectively used to receive the sensing data from A1-A3 module; FPGA(B4) as center processor, for the treatment of from MCU(B1-B3) data that receive and the data from B5 module, then send to B5 module by after the data processing received from MCU; Wherein FPGA can also substitute with other digital logic device; B5 module is preferably selects a usb data forwarding chip (preferably can adopt the FX2LP of cypress here), but should as limit, it is specifically designed to and communicates with intelligent terminal C, data after FPGA process and intelligent terminal are carried out alternately, transmission and the reception of data are subject to the control of FPGA.B1 ~ B3 module in unit B is used for receiving the data from A1-A3 module, the data received issue B5 module through FPGA process integration, B5 module can at a high speed, seamlessly carry out transfer of data with peripheral hardware (intelligent terminal), so communicated with intelligent terminal by B5 module, data transmission efficiency can be realized maximize, system transmitting-receiving process, by the control of FPGA, makes the data package size of transmission controlled, achieves real-time.
C unit: be intelligent terminal, for communicating with unit B, can see the effect of data processing on intelligent terminal.
Below the effect of each unit of this data receiving-transmitting system, module, submodule is described in more details:
A unit is made up of certain transducer and bluetooth module, and transducer is equivalent to " sense organ " of system, and bluetooth is equivalent to " nerve ", the content of transducer " impression " is sent/is delivered to " brain " process, i.e. unit B.Here in A unit, the quantity of module is unrestricted, and depending on application scenario, but quantity must be consistent with the MCU being used for receiving data in unit B, and namely sending module is equal with receiver module quantity.
Unit B is the key of whole system, and B4 module is wherein data processing and the core controlling transmission, and its process is from the data of each different sensors, and the existence of this module just achieves the concurrency of system just; B5 module is also absolutely necessary, and its effect is just used to communicate with intelligent terminal C, and be subject at high speed the control of B4 module, so just achieves the transmission of any byte size data bag.
C unit is intelligent terminal, is the window of user and system interaction, as long as meet the condition (such as possessing the driving of USB chip) of carrying out with unit B communicating, its type is unrestricted.
In embodiments of the present invention, concurrency, it is also comprehensive that the system of referring to can process the data sent from multiple transducer simultaneously, as shown in Figure 1, multiple transducer sends data by bluetooth to module B, FPGA in B module is the key component realizing concurrency, and it can process these Data Concurrents simultaneously and send.
In embodiments of the present invention, real-time, refer to that FPGA not only advanced processing can carry out the data of sensor according to demand, but also the real-time transmission of data can be realized by control FX2LP, here FX2LP is the key component sending data, as shown in Figure 1, FPGA sends data to FX2LP, after sending a packet, (data package size is any) drags down pin " PKTEND " at once, notice FX2LP sends data, then FX2LP is sent to intelligent terminal data at once, and concrete methods of realizing describes in detail below.
The control module of FPGA achieves a critical function at native system.Under legacy configuration mode, USB chip B5(FX2LP) data of fixed byte size can only be sent when carrying out data interaction with terminal, can only be 512byte(or 1024byte), namely FX2LP receives the data from FPGA always, until collect full 512 bytes just can be sent to terminal, this to the time delay needing the application of displaying data in real-time state to cause data to show, thus makes troubles.
A kind of situation, usb data forwarding chip is operated in Full-Speed mode/automatic send mode, automatically sends.In the system of the embodiment of the present invention, first the pattern of data interaction is changed into Full-Speed mode from fast mode, and the Full-Speed mode part revised in device descriptor file (DRCR.A51), the MSB of maximumpacket size (Most Significant Bit, highest significant position) change 00H into, LSB (LeastSignificant Bit, least significant bit) change 40H(64 into), so just can drop to 64byte(through repetition test needing the data byte size received from minimum 512byte, 64byte is the minimum value that can arrange under Full-Speed mode, be less than this value USB chip drives by cisco unity malfunction), the i.e. FIFO(FirstInput First Output of USB chip, pushup storage) receive full 64 bytes (example of byte-threshold) data after can automatically send, reduce the wait time delay in data transmission procedure to a great extent, concrete methods of realizing is by the file iic executable program directly burned EPROM(ErasableProgrammable Read Only Memory to USB chip, erasable programmable read-only register), so just Full-Speed mode can be entered.
Another kind of situation, usb data forwarding chip is operated in controlled sending mode, and the triggering signal according to FPGA carries out data transmission.In embodiments of the present invention by FPGA control USB chip, after FPGA completes the transmission of the data of any byte being less than 64byte, sending a low level PKTEND(low and high level more configurable) signal " notice " USB chip data is sent, the USB chip data that after receiving signal, transmission and reception are at once arrived.This controlling mechanism can realize the data transmit-receive of any byte, achieves transmission bandwidth controlled.The realization of these two functions ensure that on the one hand and the real-time of large packet achieves again the real-time transmission (small data packets as 64 or 16 even less bytes) of small data packets.

Various transducers in step 1:A unit issue bluetooth module (connection between bluetooth module and transducer is not introduced) the data obtained, and bluetooth module is gone out data retransmission to the MCU equally with Bluetooth function in unit B again.
The MCU of step 2:B unit receives data, through FPGA process (specifically how to process can according to application needs arrange) after data retransmission to USB chip, when control USB chip sends data.Here the topmost effect of USB chip be exactly high-speed seamless communicate with intelligent terminal.
Step 3: the object data specifically can monitored transducer after intelligent terminal receives the data from unit B carries out corresponding process and display, the function of finishing equipment, intelligent terminal also can send data to unit B, realize data interaction, USB chip plays the function served as bridge between FPGA and intelligent terminal here.
More specifically:
Step 1: connection correct between transducer and bluetooth module is necessary, two submodules are indispensable, and the former completes the monitoring of data, and data wireless sends by the latter, and the quantity of A module is unrestricted, can customize;
Step 2: step 2 is major parts of system, it is the key that system realizes concurrency and real-time.First be the data receiving sensor, moreover be that rationally process, from the data of multiple transducer, is finally send to intelligent terminal for user the data handled well;
Step 3: the effect of intelligent terminal is that the data utilizing transducer to detect realize certain application, it is user and the unique window communicated of equipment, and it can send data to system, and system provides feedback according to corresponding request.
