Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, a kind of home intelligent emergency call system, including control unit, temperature sensor, calling for help button, Smoke Sensor, infrared sensor, communication module, alarm, liquid crystal display, described temperature sensor, calling for help button, infrared sensor, communication module, alarm and liquid crystal display are connected with control unit respectively, described Smoke Sensor is connected with control unit by A/D converter, and described control unit sends order by communication module to each user side.
Control unit is mainly by single-chip microcomputer, crystal oscillating circuit, reset circuit, and power supply forms.STC12C5A32S2 single-chip microcomputer of the present utility model is powered as control core ,+5V power supply.Clock circuit, as one of single-chip minimum system the most most important most basic part, is used for providing clock signal to single-chip microcomputer, and circuit is changed being affected the change with clock circuit parameter by clock circuit.The input interface of clock circuit is the pin XTAL1 and pin XTAL2 of single-chip microcomputer respectively, and the clock cycle is along with using different crystal oscillator sizes can produce change, so the difference of instruction cycle.Reset circuit can ensure that circuit safety works reliably, it it is component indispensable in electronic product, system is required for resetting when startup optimization, because the data during system starts late register after Fu Weiing are all in initial state value, and system must start to start work from this original state.In native system, reset mode of operation utility model is that button resets.When carrying out reset operation, if being high level reset signal on RST pin, and keeping more than two cycles, this time, single-chip microcomputer just carried out the operation that resets.Singlechip minimum system circuit figure is as shown in Figure 2.
What burglar alarm module of the present utility model utilized is infrared human body heat releasing sensor.Home intelligent emergency call system utility model, it is also based on original household theftproof system more comprehensive and reliable Household security system plus the utility model composition of various sensor assemblies and distress call button, so the infrared sensor of the human body module module that to be native system indispensable.Infrared human body heat releasing sensor has 3 pins, No. 1 pin to connect+5V power supply, and No. 2 pins connect single-chip microcomputer, No. 3 pin ground connection.Infrared human body heat releasing sensor circuit figure is as shown in Figure 3.
Generally arriving the safety problem of family, the focal issue typically talked about is all fire-proof and theft-proof.Fire is the one of the main reasons of domestic accident, and one fire alarm circuit of utility model is the emphasis measure preventing fire from family causing heavy losses.Smoke Sensor can detect smog value, can detect again the leakage of various fuel gas, is definitely the optimal selection in home fire safety system.Therefore one Smoke Sensor module of native system utility model, model is MQ-2.MQ-2 Smoke Sensor has 4 pins, No. 1 pin to connect AO mouth, and No. 2 pins connect single-chip microcomputer, No. 3 pin ground connection, and No. 4 pins connect+5V power supply.MQ-2 smog sensor circuit figure is as shown in Figure 4.
The utility model being described above Smoke Sensor can be good at preventing family fire, but in order to make system more reliable and more stable, the utility model determines in this link of fire-proof plus a module, that is, temperature sensor, the model of selection is DS18B20.
Generally, normal room temperature typically not over 40 ° of C, only breaking out of fire or other when causing temperature too high special circumstances indoor temperature just can reach 40 ° of more than C.But some local hot weather that the most also there will be 40 ° of C summer, so in order to ensure TEMP not false alarm, so the temperature upper limit that the utility model temperature sensor is arranged is 50 ° of C, only when indoor temperature is more than 50 ° of C, and system just can send warning.The circuit diagram of temperature sensor is as shown in Figure 5.
Present family, young man's most of time works the most outside, and is typically all old old man or child stay in.If old man's suddenly disease or child are in and run into emergency situations and oneself cannot solve, once arise a problem that, be the most then to give treatment to cause aggravation not in time or strengthen economic loss, heavy then be to lose one's life.Therefore in the utility model, a particularly practical novel distress call button.When people are in alone, once suddenly disease and emergency and oneself cannot solve, distress call button can be pressed immediately, system can sound a buzzer at once warning and also send distress call information by gsm module to family, distress call button pin connects single-chip microcomputer P1.7 mouth.Distress call button utility model interface is as shown in Figure 6.
In order to make the warning function of family's emergency call system more perfect, system utility model radio warning function, it is simply that utilize gsm module to send SMS alarm to resident family.The model of gsm module of the present utility model is SIM900A.SIM900A is controlled by single-chip microcomputer, by TTL interface, SIM900A module is controlled, the TXD of single-chip microcomputer is connected to the RXD of SIM900A, the RXD of single-chip microcomputer is linked on the TXD of SIM900A, realizing reception and the transmission of string data, GND is connected on GND[15].GSM interface circuit is as shown in Figure 7.
Liquid crystal display of the present utility model is to utilize LCD liquid crystal display screen.Need real time temperature in clear and intuitive display room on display screen, whether Smoke Sensor reports to the police, whether whether infrared sensor of the human body reports to the police, in the state of deploying troops on garrison duty, and whether system sends distress call and reports to the police, it is possible to use the display result on LCDs checks that whether whole system is in normal work.The utility model is to show with 12864 liquid crystal displays, and 12864 liquid crystal displays have 12 pins, and No. 6 pins connect+5V power supply, No. 7 pin ground connection, and other pins connect single-chip microcomputer.12864 liquid crystal display circuit figures are as shown in Figure 8.
Either pass by or now, alarm is the indispensable module of each family emergency call system.Alarm of the present utility model is buzzer.Buzzer, after alarm signal sends, sends sound ear-piercing as buzzing, and such sound directly can make invader escape in alarm and can cause the attention of neighbouring resident.Buzzer is to utilize 8550 triodes to be amplified, and base stage connects single-chip microcomputer, grounded collector, and emitter stage connects buzzer positive pole, and buzzer connects+5 power supplys.Buzzer circuit figure is as shown in Figure 9.
Finally illustrate is, preferred embodiment above is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from the utility model claims limited range.
