Abstract

The invention relates to an automatic control system, and in particular relates to an automatic crisis triggering system for an old person. The automatic crisis triggering system for the old person is characterized in that analog signals collected by four composite sensors are combined and transferred into a singlechip control circuit; the singlechip control circuit monitors an obtained digital signal by virtue of an internal analog-digital converting circuit; and when a monitored numerical value exceeds a threshold valve range and external interrupt information is not obtained within 20s, a buzzer on a singlechip driving system gives an alarm to people nearby for seeking help. The system consists of an acceleration signal collecting circuit, a concentration signal collecting circuit, a heartbeat signal collecting circuit, a body temperature signal collecting circuit, the singlechip control circuit, a power supply, a keyboard, a display screen, an indication lamp and the buzzer. The automatic crisis triggering system for the old person, which is provided by the invention, has a simple hardware structure, complete functions and low power consumption, and is particularly suitable for the old person.

Description

The automatic triggering system of a kind of the elderly's crisis

Technical field

The present invention relates to a kind of automatic control system, relate in particular to the automatic triggering system of a kind of the elderly's crisis.

Background technology

At present, China has progressively entered aging society, and the aging problem has obtained the concern of society day by day, and old man's health and mental status are subjected to people's attention day by day.In view of the situation, the characteristics that a lot of companies and producer descend according to old man's physical function, as visual deterioration, auditory dysesthesia, hand tremble, the appearance of phenomenon such as physical fatigue, begin to research and develop make be suitable for giant-screen, big font, big key and conversation that the elderly uses because of mobile phone, but, mobile phone generally all has radiation, is subjected to electromagnetic radiation of mobile telephone can cause health bad reactions such as headache, dizziness for health for a long time concerning the more responsive the elderly of radioreaction; In addition, present mobile phone brand, type and function is more and more, and the complicacy of operation is also brought a lot of difficulties to the elderly.Therefore, it is necessary designing the automatic triggering system of crisis that a kind of the elderly is suitable for.

Invention description

The objective of the invention is to design a kind of can the automatic triggering system of the elderly's crisis; promptly to the elderly inherent occur fall in a swoon, tachycardias and slow, fervescence symptom and outside ETS of living in and combustable gas concentration detect and report to the police with excessivelying, makes the elderly obtain succouring in the very first time.

The present invention relates to the automatic triggering system of a kind of the elderly's crisis, the automatic triggering system of described crisis comprises acceleration signal Acquisition Circuit, concentration signal Acquisition Circuit, heartbeat signal Acquisition Circuit, body temperature signal acquisition circuit, single chip machine controlling circuit, power supply, keyboard, pilot lamp and hummer.It is characterized in that it may further comprise the steps:

The first step, after system powers on, the beginning initialization.

In second step, acceleration signal Acquisition Circuit, concentration signal Acquisition Circuit, heartbeat signal Acquisition Circuit and body temperature signal acquisition circuit are gathered the motion state of human body, smokescope, human heart rate and the body temperature signal of surrounding environment respectively.

In the 3rd step, single chip machine controlling circuit obtains four road signals that four signal acquisition circuits provide, and judges whether the signal of gathering exceeds threshold range.

In the 4th step, after signal exceeds threshold range, carry out buzzing and report to the police.

Above-mentioned acceleration signal Acquisition Circuit is core with the acceleration transducer, whether be used to detect the old man is in and falls, when human body is fallen because of physical problems such as stupor, apoplexy cause, health has the phenomenon that is similar to freely falling body to occur, whereby, single chip machine controlling circuit can be judged old man's motion state by the information of obtaining.

Above-mentioned concentration signal Acquisition Circuit is core with the gas sensor and since the gas that contacted in the family of old man important be coal gas, i.e. methane gas, when methane gas concentration surpassed 0.1%, single chip machine controlling circuit started hummer.

Above-mentioned heartbeat signal Acquisition Circuit is core with the heart rate sensor, the heartbeat situation of human body, and when heartbeat was outside 60～100, single chip machine controlling circuit started hummer.

The said temperature signal acquisition circuit is core with the temperature sensor, the human body shell temperature, and when temperature was outside 36～37.2, single chip machine controlling circuit started hummer.

The present invention can detect the common condition that the old man may occur at any time, and as fervescence, fall and aroused in interest too urgent slow excessively etc., and the old man is in the air condition of environment, is suitable for the elderly and uses.

Below by drawings and Examples the present invention is described further:

Fig. 3 is the elderly's crisis triggering system software flow pattern of saving oneself.

Embodiment

The elderly's crisis is saved oneself the outside synoptic diagram of triggering system as shown in Figure 1; system's external structure is simple, is made up of power key, options button 1 and options button 2, cancel key, hummer, display screen, power light, acceleration pilot lamp, concentration pilot lamp, heartbeat pilot lamp and temperature indicator.Press power key, power light is bright, and system begins initial work; The signal value that occurs on options button 1 and options button 2 control display screen, when

options button

1 and 2 is all upspring, display screen shows accekeration, when options button 1 upspring options button 2 when pressing display screen show gas concentration, display screen shows heart rate value when options button 1 is pressed options button 2 and upspring, display screen shows the body temperature value when options button 1 and options button 2 are all pressed, and lights different LED lamps and point out when showing different data on the display screen; Single chip machine controlling circuit detects the signal that collects and is in when unusual, starts hummer, and the old man also can under normal circumstances stop buzzing by cancel key.

The elderly's crisis is saved oneself the triggering system structural representation as shown in Figure 2, and system comprises acceleration signal Acquisition Circuit, concentration signal Acquisition Circuit, heartbeat signal Acquisition Circuit, body temperature signal acquisition circuit, single chip machine controlling circuit, power supply, keyboard, display screen, pilot lamp and hummer.The major function of single chip machine controlling circuit has the information that receives four road signal acquisition circuits, and an information stores that collects can be checked historical data at any time in storer; Judge whether signal is normal, when signal is outside critical field, start buzzer warning; Receive the external demand of options button and cancel key, and carry out corresponding order.

The elderly's crisis is saved oneself the triggering system software flow pattern as shown in Figure 3; after system powers on; the beginning initialization, single chip machine controlling circuit at first obtains acceleration signal, judges whether acceleration signal exceeds threshold value; if exceed threshold value; then start the 20s timer, if not cancellation in the 20s then starts hummer; otherwise single chip machine controlling circuit is gathered concentration signal, heartbeat signal and body temperature signal successively, and makes corresponding judgment.

The present invention utilizes four kinds of sensor acquisition circuit and single-chip microcomputer and peripheral circuit construction system thereof, and that simple in structure, chip uses is less, electromagnetic radiation is little, has the buzzing warning function, is fit to the elderly and uses.
