Embodiment

As shown in Figure 1, based on the alarm preventing self-burning of vehicle of distributed temperature collection, comprise the multiple temperature sensors be arranged in automobile, described multiple temperature sensor connects one-chip computer module, and one-chip computer module connects clock module, hummer, memory module, GPRS module, Keysheet module, LCD MODULE respectively.This alarm also comprises power module, and described power module connects clock module, hummer, memory module, GPRS module, Keysheet module, LCD MODULE, one-chip computer module, temperature sensor respectively, for these modules provide power supply.

Automobile is after extraneous sunburst irradiation or long-play, vapour vehicle interior temperature can raise gradually because absorbing extraneous heat, if heat can not distribute in time, the heat be finally accumulated in car arrives to a certain degree and car body burning will be caused to scrap.Alarm before runtime, needs to carry out setting parameter by Keysheet module, and comprise the setting, date and time parameter etc. of threshold temperature setting, phone number, LCD MODULE can show the data of inquiry.The threshold values of reporting to the police for different vehicles, different parts, different times is different, manually can carry out corresponding adjustment.The utility model adopts DS18B20 type temperature sensor as collecting unit, carry out multiple key point temperature detection in a distributed manner, " one-wire bus " mode of employing signal transmission, makes system have good antijamming capability, can adapt to various harsh climate condition and strong-electromagnetic field interference environment.Once the temperature at certain position of automobile occurs abnormal, system automatic alarm, LCD MODULE Lock Part, highlighted state display problem information, hummer sends chimes of doom, utilize GPRS network that abnormal information is sent to car owner simultaneously, break through geological restraint, the possibility that self-burning of vehicle occurs can be effectively reduced.

In addition, the system integration has the storage element of clock, and when auto repair is maintained, the Data Dynamic information that observing and controlling early warning system is preserved, provides reference, so that find problem place in time to the maintenance of automobile and problem investigation aspect.Operationally, temperature detecting module constantly detects the temperature of vehicle key position or Primary Component to warning system, and the temperature threshold of temperature and setting compares by one-chip computer module, if the vehicle interior temperature detected exceedes temperature threshold, then and system alarm.It is that LCD screen exceedes the key position of temperature threshold and corresponding temperature information with highlighted state display that type of alarm devises three kinds: one, two is that hummer sounds at once, to reach the object of reminding car owner, three is that system sends warning note by GPRS module, car owner may owing to not sensing note in busy state, if car owner does not take corresponding measure in a period of time after receiving note, then can dial car owner's phone to remind, first two alerting pattern is the situation of car owner in car, if car owner is not in car, then can start the third type of alarm.To cause due to factors such as reflection, decay to prevent the propagation of hummer sound that propagation distance is short, spread scope is not shortcoming very widely, this warning system transmits note by GPRS network, and at short notice by Advise By Wire car owner, make full use of the propagation distance of wireless telecommunications far not by the advantage of region restriction, consider the otherness of sound and microwave two kinds of circulation ways, profit is advantage work separately in two ways, propagates range of application for universal two kinds.The highlighted display of liquid crystal, makes full use of the sensitivity characteristic of human eye to light, attracting notice.This alarm can effectively be removed a hidden danger in time before self-burning of vehicle occurs, and avoided the heavy losses of property.

Principle of work:

First, before system commencement of commercial operation, need to carry out initial value setting according to work time of automobile and automobile model to parameters.System make use of the knowledge of burning-point, the temperature threshold of setting must lower than the ignition temperature of parts, otherwise just do not reach the object of temperature monitoring, if the temperature that the temperature threshold arranged is greater than the ignition temperature of parts or setting is too low, then system can be pointed out by hummer, LCDs highlighted prompting " can input unsuccessful, please re-enter ".Telephone number points out car owner to fill in car owner's telephone number before arranging, and fill in twice, two telephone numbers are compared, identical then prompting inputs successfully, difference then LCDs can highlighted prompting " input unsuccessful; please re-enter ", in case information solicitation mistake causes warning system in time dangerous situation can not be conveyed to car owner.Arrange successfully in initial parameter, then warning system can be run, when system works, first the temperature of car automobile significant points is examined by sensor DS18B20, digital data transmission is converted to single-chip microcomputer by the chip of inside, single-chip microcomputer is undertaken storing, calculating by receiving the signal of coming, and judges that whether abnormal temperature information is.The basis for estimation of this part mainly contains 2 points: one is the temperature threshold whether temperature of these parts reaches setting, two is that whether excessive temperature ascensional range is namely at short notice at this position, if detect that temperature occurs extremely will starting warning system, type of alarm has three kinds: one to be that LCD screen exceedes the key position of temperature threshold and corresponding temperature information with highlighted state display, two is that hummer sounds at once, three is that system sends warning note by GPRS module, if car owner does not take corresponding measure in a period of time after receiving note, then clawback main telephone of calling a taxi is reminded.This warning system not only can be real-time temperature is monitored, also when automobile maintains, also can the temperature information of automobile component that stores of extraction system, according to the temperature of dynamic change, analysis device duty, check targetedly, thus conveniently fix a breakdown, save time

Fig. 1 is system design scheme, mainly comprises distributed DS18B20 temperature sensor, power module, clock module, Keysheet module, LCD MODULE, GPRS module, hummer, memory module, computer acquisition system.DS18B20 temperature sensor carries out Real-Time Monitoring to the temperature of the key position in automobile, the temperature information of collection is passed to single-chip microcomputer in time and processes.

Power module is for providing the power supply needed for alarm, and power module adopts lithium battery.

Clock module not only can record data and occur the time of these data, can also record the data point that some acquires a special sense.Clock module adopts DS1302 real-time clock module.

LCD MODULE is used for the information such as temperature of displaying time, key position.LCD MODULE adopts Samsung LTM238DL01-C01 screen.

GPRS module realizes sending short messages between alarm and car owner making a phone call to carry out warning function.Hummer is for the sound given a warning and warning etc. is similar; The real-time storage that memory module is mainly used in data comprises the information such as time, temperature, telephone number.

Fig. 2 is system flowchart, first be system initialization, read the information such as temperature alarming bound and brightness, then the judgement of initial value setting is carried out, initial value arrange successfully after automatic cycle detect each sensor temperature go forward side by side trip temperature pace of change detect, if any one exceedes the threshold value of setting, hummer and liquid-crystal apparatus are reported to the police, clock module starts timing, reported to the police by phone after arriving the corresponding time interval, if do not exceed the threshold value of setting, memory module stored time and temperature data in the corresponding time interval, corresponding data output is carried out when needs carry out data transmission.
