Description

Safety alarm bell

The utility model relates to a kind of safe reminiscences.

The various safety misadventures of annual in the world generation, personal casualty that causes and property damage are surprising.The U.S. is annual because the personal casualty that various accidents cause reaches millions of people.With regard to the etesian traffic accident of China, according to Ministry of Communication's statistics of Jan-Sept calendar year 2001,59.4 ten thousand of road traffic accidents take place in the whole nation, cause 7.1 ten thousand people's death, and 42.2 ten thousand people are injured, respectively than increasing by 32.2% and 35.9% the same period in 2000.Wherein the accident that causes owing to the reason of chaufeur accounts for more than 70% of accident total amount.Because the awareness of safety of raising and reinforcement chaufeur helps to reduce the chance of its mis-use breakdown, so, relatives, higher level, supervisory management zone can be described as earnestly and maternally the safety prompting and the safety education of chaufeur, but this artificial prompting can not be accomplished whenever and wherever possible eventually, chaufeur has just been reminded later two, three days often, safe consciousness is also higher, and the time is long slightly, has just desalinated.2002 the 3rd phases of " CYBERSPACE " magazine have been introduced the driver fatigue reminiscences, and it judges according to the variation of phenomenon chaufeur nictation whether chaufeur has been in the fatigue state of driving, and give the alarm and shake seat according to judged result and remind chaufeur.Though this class reminiscences is fine, but the whole difficulty of the design philosophy of this logical formula is dealt with variety, polytropy, complexity, randomness, the delicate property of the factor of influence safety, such as realizing unfavorable conditions such as thin, absent minded for driver safety, this class reminiscences is just had no way of doing it.In safety traffic is reminded, so, in the prevention of other safety misadventure is reminded, also be similar state.

The utility model proposes a kind of safe reminiscences, it with do not say logic, without asking about the circumstances or causes, the mode of randomness carries out safe prompting to being alerted the people in full automaticity ground whenever and wherever possible, make and be alerted the people and can keep higher safe consciousness for a long time, play tightening security, the purpose of minimizing accident chance of occurrence.

Set forth scheme of the present utility model below.For the convenience that illustrates and concrete, specially reminding with running safety is that example is set forth, and the utility model reminds the utilization scheme substantially identical therewith in the safety in other field.

Adopt the reminiscences of alarm bell formula moulding, place in the operator's compartment, chaufeur can observably be seen or experience, and is carved with " Safety alarm bell " or epigrams such as " safety at me in the heart " on the alarm bell.Produce the alarm bell sound of gradually sending out at random with electronic component in addition, also have record to remind voice, perhaps record statement, send at random to not timing from chaufeur oneself warning, self stimulation from the relatives and friends of chaufeur or the safety of upper management department.

Since above scheme, the atmosphere that can in operator's compartment, cause a kind of Safety alarm bell to yowl, thus the safe consciousness of chaufeur is strengthened fully, thus the chance that the reduction accident takes place.And because the generation of alarm bell sound is a ccasual, chaufeur can not know in advance that adding is on-the-spot the prompting, so often can play the effect of a blow and a shout warning, suddenly the heart is frightened to make chaufeur, thereby corrects one's attitude, and drives with caution.This utility model reminds occasion also similar effects can be arranged safely at other.

Also in conjunction with the accompanying drawings the utility model is explained in detail with two embodiment below.

Fig. 1 is an overall diagram;

Fig. 2 is installation form figure;

Fig. 3 is an electrical schematic diagram;

Fig. 4 is the randomness impulse deviser schematic diagram of second embodiment.

With reference to figure 1:[1] be the clock body, link to each other with base [3] by connecting rod [2].[4] be universal-joint on the base, to regulate the link supports angle, to adapt to various inclined tables.Clock body [1] is gone up with " Safety alarm bell " four eye-catching big words.[5] be top cover, be spun on the clock body [1], promptly expose electrical appliance part after outwarding winding with screw thread.Electrical appliance part is made up of three parts, is respectively circuit board module module [6], small rechargeable pond group [7], loudspeaker [8], has sound releasing hole below loudspeaker [8].On circuit board module module [6], be provided with electrical control part, be respectively source switch [9], randomness size adjustment knob [10], Electret condenser microphone [11], charging socket [12], recording operation button [13], caution sound select switch [14].

Fig. 2 is that this utility model is installed other several forms of putting, and wherein a is positive hanging, and b is an inclined suspension type, c is a suspension type, d is the form that all electronicies package is placed base, and e places base with circuit board module, battery, and loudspeaker is placed the form of Zhong Tizhong.

Fig. 3 is the electrical schematic diagram of first embodiment: IC ₂And IC ₃8 joint denial gates form 4 R-S binary pairs, because this R-S binary pair is when R, S input end are all high level " 1 ", or when becoming low level " 0 " by high level " 1 ", the level of mouth Q end will be in nondeterministic statement, random state just, like this whenever the input end of these 4 R-S binary pairs during in high level or low level, IC ₅A ccasual binary-coded decimal will appear in 4 input end A, the B of CC4028, C, D, and CC4028 is translated into a decimal digit with being about to it.IC ₁Constitute an oscillator, its output pulse makes the level height variation constantly of these 4 R-S binary pair input ends, so IC ₅Mouth decimal digit at random will appear one by one.IC ₆CC4043 constitutes a password setting and to decoding circuit, its 4 R terminate at IC ₅On ten mouths any 4 constitute one group of 4 figure place password.If certain coincidence, IC ₅4 random numbers that occur continuously on the mouth are identical successively with the password that is provided with just, password centering then, negative going pulse of M place appearance.If 4 numbers do not have centering, then IC ₆Will be by IC ₄The pulse-scaling circuit that CC4017 constitutes resets, and it is right to restart.Regulate R ₂Can change IC ₁Oscillation frequency, changing the speed that random number takes place, thereby regulate the size of randomness.After centering, a negative going pulse appears in the M place, triggers IC ₇Simulation alarm bell sound integrated circuit, IC ₇Output alarm bell acoustical signal is through BG ₃, BG ₄The power amplifier of forming promotes loudspeaker and slowly sends overcast alarm bell sound.IC ₈Be fixing speech IC, interior contain " is taken care " or " safety is maximum economic benefits " waited and warned voice, if K switch ₂Beat at 1, then after alarm bell sound finishes, by C ₂, C ₃, BG ₁, BG ₂The continuous trigger circuit of forming will trigger IC ₈Send voice.IC ₉Be the speech recording and reproducing integrated circuit, relatives, higher level, friend, competent authorities or the chaufeur by chaufeur passes through K at ordinary times ₃, K ₄, MIC words that safety is reminded record, if K switch ₂Beat at 2, then after alarm bell is rung, IC ₉The playback that will be triggered, the safety warning of being recorded will be sounded in one's ear at chaufeur.
