Below in conjunction with accompanying drawing and specific embodiment, the present invention is further detailed explanation.
As shown in Figure 1, warning system of the present invention is a GSM message burglar alarm system, comprise infrared induction module, main control singlechip, communication module, audible-visual annunciator and Intelligent mobile equipment, the signal output part of described infrared induction module connects the signal input part of main control singlechip, the control output end of described main control singlechip connects audible-visual annunciator, and connects Intelligent mobile equipment by communication module.
Infrared induction module of the present invention is the key of whole warning system, comprise thermal infrared sensor and signal processing circuit, the window that filter glass is housed is offered on the top of described thermal infrared sensor, the wavelength coverage of the light that described filter glass can pass through is 7 ~ 10um, the infrared ray centre wavelength of animal radiation is 9 ~ 10um, and the wavelength sensitivity of detecting element almost stable within the scope of 0.2 ~ 20um is constant, so thermal infrared sensor of the present invention is just in time suitable for the detection of animal infrared radiation, and the infrared ray of other wavelength is absorbed by optical filter, so just, define a kind of special infrared ray sensor being used as detecting animal radiation, described thermal infrared sensor can should go out with non-contacting form feeling the infrared signal that animal gives off, and send to signal processing circuit.
Described signal processing circuit converts described infrared signal to electric signal, and send to single-chip microcomputer after being amplified by this electric signal, after single-chip microcomputer carries out analyzing and processing to described electric signal, alerting signal is sent to audible-visual annunciator, carry out sound and light alarm, send alarming short message to the Intelligent mobile equipment of equipment person in charge by communication module simultaneously.
As shown in Figure 2, signal processing circuit adopts BISS0001 chip, and BISS0001 chip is a transducing signal process integrated circuit with superior performance, is converted to electric signal for the infrared signal exported by thermal infrared sensor, and carries out amplification process.Infrared inductor is input to prime amplifier OP1 and amplifies, and is then coupled by C4 and carries out second level amplification to operational amplifier OP2.Form after two-way amplitude discriminator process through over-voltage comparator COP1 and COP2 again, detect effective trigger pip deactivation delay time timer output signal, then enter single chip part through R3 and process.Two-way amplitude discriminator, effectively can suppress interference.
Delay cycle carrys out regulation output by R12, as long as saltus step in Vs generation in delay time, Vo will continue to extend one-period from jumping moment on Vs, and the electric capacity in circuit is in order to better control the timer in chip, if Vs remains high level always, so just can be transferred in single-chip microcomputer by P10 and be for further processing.And regulate R13 according to different required distances, maximumly can be adjusted to about 7 meters.In figure in BISS0001 1 pin with wire jumper connect one connect high level after, if there is toy to appear in its induction range in delay time section, its output will keep high level always, until animal leaves rear ability, and high level is become low level, this circuit design is exactly can triggering mode.
Main control singlechip of the present invention is STC89C52 single-chip microcomputer, is a kind of low-power consumption, high-performance CMOS 8 8-digit microcontroller, has 8K flash storage able to programme.Use the manufacture of high-density nonvolatile memory technology, with the instruction of industrial 80C51 product and pin completely compatible.On sheet, Flash allows program storage online programmable, is also suitable for conventional programming device.On a single chip, have 8 dexterous bit CPUs and in-system programmable components Flash, height is flexible, the solution of super efficient for numerous embedded Control application system provides to make STC89C52.STC89C52 has following standard feature: 8k bytes Flash, 256 byte RAM, 32 I/O mouth lines, WatchDog Timer, 2 data pointers, three 16 bit timing device/counters, one 6 vector, 2 grades of interrupt structures, full duplex serial port, crystal oscillator and clock circuit in sheet.In addition, STC89C52 can be down to the operation of 0Hz static logic, supports that 2 kinds of software-selectable select energy-saving mode.Under idle pulley, CPU quits work, and permission RAM, timer/counter, serial ports, interruption work on.Under power down protection mode, RAM content is saved, and oscillator is frozen, and all work of single-chip microcomputer stop, and interrupt or hardware reset until next.This module burns into program code centered by single-chip microcomputer, and then periphery connects the submodules such as reset circuit, oscillatory circuit, Keyboard Control, LED display circuit, warning circuit.
As shown in Figure 3, described communication module is the gsm module of TC35 series, TC35 module is the high performance communication module that German SIEMENS company produces, primarily of GSM baseband processor, GSM radio-frequency module, supply module, ((ASIC), flash memory, ZIF connector, antennal interface six part composition, supply module is used for powering for GSM baseband processor, GSM radio-frequency module and ZIF connector.Gsm module curent change is very large, and time idle, electric current is less than 3mA, and during conversing, electric current is maximum reaches 2A, and this just proposes higher requirement to feed circuit.ZIF zero insertion force (Zero Insertion Force), refer to a type, do not have concrete size, ZIF (zero insertion force) connector, reliability is high, and signal cross-talk is little.
Described warning system comprises display circuit, and described display circuit is 1602LCD display, is connected to the signal output part of main control singlechip.1602LCD is divided into band backlight and be not with backlight two kinds, and base controller major part is HD44780, is with thick or not backlight of the ratio of backlight, whether is with backlight also indifference in the application.
As shown in Figure 4, when there being toy to swarm into transformer station, described infrared signal is sent to signal processing circuit after the infrared signal that toy gives off being detected by thermal infrared sensor; Described signal processing circuit converts described infrared signal to electric signal, and sends to single-chip microcomputer after being amplified by this electric signal; After single-chip microcomputer carries out analyzing and processing to described electric signal, send alerting signal control alarm and report to the police, send alarming short message by communication module to equipment person in charge simultaneously; After equipment person in charge receives note, long-range sending to alarm is closed or reset command, confirms whether alerting signal repeats to send, and has judged whether that doubtful toy swarms into transformer station, to improve the reliability of warning.
The actual induction scope of infrared sensor should be 0-7m in theory, by test, to 7m from 0m, the scope wherein arriving 6.3m can sense, but starting to occur that induction is ineffective time 6.5m, may be mainly occur a little electronic interferences, and line error.But be applied in narrow and small environment in cable duct, hole, alarm distance is enough effective.
Warning system of the present invention is when sensing animal, and system sends sound and light alarm signal, and display alarm signal in LCD display, SMS alarm that the Intelligent mobile equipment simultaneously to equipment person in charge sends " noting: have toy to enter ".Achieve warning and identify warning, reduce the probability of wrong report simultaneously, make to design hommization more.In the actual environment of transformer station, because the environment such as hole are narrow and small, once after toy is scurried out, Infrared intrusion detector sends sound and light alarm signal at once without delay.The present invention is a kind of cheap, dependable performance, intelligentized warning system, when can swarm into suddenly toy in transformer station, provide warning information with the shortest time to equipment person in charge, improve the reliability and promptness of reporting to the police, and improve reliability and the security of power supply further.
