Compared with prior art, the beneficial effects of the utility model are:
1, this utility model is applicable to the real-time remote human body pulse information that use school, gymnasium etc., and the pulse information that detects is stored in the host computer conveniently to inquire about and to call.
2, this utility model can adopt the 802.11bWiFi transmission technology, has realized short distance high speed wireless data transmission, with Real-time Collection in the pulse watch to pulse information be transferred in the computer.
3, this utility model also can pass through button choice for use ZigBee wireless transmission, and it is lower that ZigBee and WiFi compare power consumption, but transfer rate not as WiFi, this can be selected voluntarily by user.If ZigBee will transmit a lot of classmates' data when carrying out body examination the time, can select in school, power consumption is little like this.
4, this utility model adopts voice broadcast function directly to report the health of user with phonetic function.
The specific embodiment
For this utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
As shown in Figure 1, a kind of wireless pulse measurement device that has voice broadcast function based on WIFI that this utility model provides comprises microprocessor, microprocessor adopts 51 very high single-chip microcomputers of cost performance, realizes signals collecting, date processing, data send, the functions such as voice broadcast.Microprocessor connects respectively pulse collection and display module, ZigBee wireless transport module, key-press module, WiFi wireless transport module, voice broadcast module and power module, and power module also connects pulse collection and display module, ZigBee wireless transport module, WiFi wireless transport module and voice broadcast module.
In the present embodiment, power module adopts and uses rechargeable battery to get final product.
Pulse collection is connected middle fracture and is connected with microprocessor with display module.Pulse signal collection is realized by piezoelectric film sensor, because beat pulse is very faint, so be easy to be subject to outside interference, cause the signal of sensor output that interference is arranged, so adopt debouncing circuit to go interference to send into microprocessor by middle fracture again to the signal of sensor output.
Microprocessor module is connected the UART interface and connects with the WiFi wireless transport module.The built-in WIFI communication protocol of WiFi wireless transport module and serial communication protocol, single-chip microcomputer sends different instruction to the WiFi wireless transport module, such as network being set, connection server by serial ports.The WiFi wireless transport module is connected to the network of Route establishment, is connected to the server software terminal on the PC.
Be connected by the UART interface between microprocessor module and the ZigBee wireless transport module.The built-in ZigBee communication protocol of ZigBee wireless transport module and serial communication protocol.The ZigBee wireless transport module uses two ZigBee wireless transparent transmission modules, is set to respectively coordinator and router.These two module self knitmesh are connected with PC and microprocessor respectively again, and data communication device is crossed the ZigBee wireless transport module and passed on the PC like this.
Key-press module adopts 4 to take advantage of 4 matrix keyboards.The voice broadcast module directly is connected with the IO mouth of microprocessor, ISD4004 carries out subsection record and broadcast multiple segments voice separately with I/O mouth simulation SPI control, with the input of MIC microphone and tone frequency channel wire input circuit, output adopts LM386 to amplify as sound, directly drives the loudspeaker about 8 Europe, 4W.
Work process of the present utility model is as follows:
After device is opened, system finishes initialization operation, the sort of transmission means is selected in display module prompting in pulse collection and the display module, if require to select WiFi to connect by button choice for use WiFi transmission or ZigBee transmission button according to user, then microprocessor by the UART interface send instruction to based on the WiFi wireless transport module of WiFi so that watch is connected the connection communicable state with the upper computer end server software.Host computer is made of ordinary PC, and host computer is connected with wireless router.If select ZigBee to connect, two are set to respectively router and are connected ZigBee wireless transparent transmission module with coordinator and carry out voluntarily knitmesh by Zigbee protocol and connect.Coordinator is connected with PC, and router is connected with single-chip microcomputer.Single-chip data is issued router, router by and coordinator between the networking set up transfer data on the PC.
Behind the start detection pulse button, pulse transducer is crossed microprocessor external interrupt interface with the data communication device that collects and is sent into microprocessor and process.The data that obtain show by the display module in pulse collection and the display module on the one hand, and by the report of voice broadcast module, by WiFi wireless transport module or ZigBee wireless transport module data are sent in the upper computer software on the other hand, upper computer software can record received data and data can be saved among the data base, finishes real-time demonstration and preservation to pulse.
