Description
Technical field
What this utility model crutch related to is a kind of intelligent alarm crutch.
Background technology
Multifunctional intellectual alarm crutch can guarantee to continue multi-functional, the intelligentized service product of human nature of research on the basis of original Intelligent crutch.Original Intelligent crutch is image and hommization not, and the function of demonstrating is single especially, simple, and this just needs a kind of novel technology to improve these deficiencies, to adapt to actual human needs, meets the life of human intelligence.
GPS navigation instrument operation principle:
In conjunction with Fig. 5 and Fig. 6, gps system comprises three parts: satellite portion-gps satellite, ground control section-ground monitoring system and the actual environment division-gps signal receiver that uses.GPS navigation overall process may be summarized to be three steps: location, calculating and navigation.
1, location: omniselector positions via satellite, finds out current location.By built-in aerial, received after satellite high-frequency signal, normal job demand is received 4 satellites simultaneously, by CPU, is analyzed, calculates, is processed, and draws specifically through, latitude, then matches on map and shows;
2, calculate: after input destination, by navigation software system, in navigation electronic, enter
Line number according to the retrieval, is found out destination, according to the location of previous step, calculates the road from location to destination;
3, navigation: the satellite-signal that omniselector receives, navigation software can be by locator data and map data base real-time matching, thereby instructs hardware suggestion voice, and demonstrates how to walk on liquid crystal display screen.
The relevant explanation of running figure:
One, UART0 is that the communication interface UART of a microprocessor is Universal Asynchronous Receiver & dispensing device, and 0 is numbering, has 1,2, a 3...... etc.
Two, GSM is global system for mobile communications.
Three, PX is a kind of measurement grade of current transformer
Four, the asynchronous transmission standard interface that RS-232 is formulated by Electronic Industries Association (Electronic Industries Association, EIA).Conventionally RS-232 interface occurs with 9 pins (DB-9) or the kenel of 25 pins (DB-25), on general personal computer, has two groups of RS-232 interface, is called COM1 and COM2.
Five, CygnalC8051F series monolithic be the SOC(system on a chip) SOCCPU that really can work alone effectively management simulation and digital peripherals can close single or whole peripheral hardwares to save power consumption FLASH memorizer, also there is ability at anchor line (string) reprogramming and can be used as program storage and can be used as in non-volatile data storage again.
CygnalC8051F series monolithic adopts CIP51 kernel, the program of the ASM51Keil C high-level language exploitation compiling C8051F series monolithic of Cygnal instruction and the complete compatible available standards of MCS51 instruction system
8051 machine cycles of standard will take 12 system clock cycles and carry out that instruction is minimum to be wanted a machine cycle CygnalC8051F series monolithic instruction process to adopt the pipeline organization machine cycle to reduce to 1 system clock cycle instruction process energy force rate MCS51 by 12 system clock cycles of standard greatly to improve.
In conjunction with Fig. 7, Fig. 8 and Fig. 9, blood pressure sensing filter amplification circuit adopts BP01 type pressure transducer and amplifier MAX4472.BP01 type pressure transducer is custom-designed for detecting blood pressure, is mainly used in Portable Electronic Blood Pressure Monitor.It adopts accurate thick film ceramic chip and nylon plastic(s) encapsulation, has high linearity, low noise and the little feature of extraneous stress; Adopt inner demarcation and temperature-compensating mode, improved certainty of measurement, stability and repeatability, within the scope of gamut, precision for ± 1%, zero point the be not more than ± 300 μ V that lack of proper care.MAX4472 is a integrated low-power consumption amplification chip of four operational amplifiers of MAXIM company.In native system, inner integrated transporting discharging A connects constant-current source, for pressure transducer provides constant electric current, and amplifier B and amplifier C, amplifier D forms difference input, Single-end output amplifying circuit, directly inputs ADC0 and monitors blood pressure DC component.
Blood pressure sensing filter amplification circuit is comprised of filtering and amplification two parts.Wherein MAX267 is the integrated filter that MAXIM company produces, can form that low pass, band are logical, high pass, etc. various ways, use flexibly, performance is far superior to the filter circuit that adopts integrated transporting discharging to form.MAX4471 is the amplifier of a low-power consumption of MAXIM company.MAX9028 is the comparator of a low-power consumption of MAXIM company.The signal that filter circuit adopts MAX267 to form band filter permission 0.8～38Hz passes through, the high-frequency noise and the power frequency that filter flip-flop in signal and power supply and skin and cuff friction are disturbed, then through MAX4471, further amplify, obtain the voltage signal of single-chip microcomputer coupling, enter ADC2, monitor the AC compounent of blood pressure.This signal converts pulse signal to by low power consumption comparator MAX9028 simultaneously, triggers ADC1 work.
