Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
As shown in Figure 1, the anti-overload human body recognition system of a kind of vehicle, it is characterized in that: comprise Single Chip Microcomputer (SCM) system 1, infrared sensor signal processor 2, human body pyroelectricity infrared pickoff 3 and wireless communication module 7, the input end of described Single Chip Microcomputer (SCM) system 1 is connected with infrared sensor signal processor 2, the mouth of described Single Chip Microcomputer (SCM) system 1 and digital pipe display circuit 4, control relay circuit 5 is connected with loud speaker warning circuit 6, the input end of described infrared sensor signal processor 2 is connected with human body pyroelectricity infrared pickoff 3, the mouth of described human body pyroelectricity infrared pickoff 3 is also connected with wireless communication module 7.
Wherein, infrared sensor signal processor 2 adopts infrared thermal release electric process chip BISS0001, and human body pyroelectricity infrared pickoff 3 adopts multiple human body pyroelectricity infra-ray sensing module RE200B, and wireless communication module 7 adopts CC2430 wireless communication chips.
Human body pyroelectricity infra-ray sensing module RE200B is as passive type infrared switch, it can detect the infrared radiation that human body sends in a non-contact manner, and effectively can suppress the outer interference emission beyond human body radiation wavelength, system utilizes the monitoring of its feature to judge passenger vehicle seating capacity just.In order to strengthen the stability that sensor signal exports, so that micro controller system correctly processes, and then improve system stability, system adopts four-operational amplifier, compares and enlarges the output signal of human body pyroelectricity infra-ray sensing module RE200B.
Because infrared thermal release electric process chip BISS0001 operating voltage range should at 3V-5V, and require higher to level smoothness, otherwise clutter affects the process of chip to signal, system carries out voltage stabilizing by AMS1117 voltage stabilizing chip to VCC, provides burning voltage to it.
The principle of above-mentioned sensing module is: when some crystal are heated, can produce the electric charge that quantity is equal and symbol is contrary, i.e. pyroelectric effect at crystal two ends.Human body has constant body temperature, generally at about 37 DEG C, can send the infrared ray of about 10 μm specific wavelengths.RE200B infrared pickoff, coordinates infrared thermal release electric process chip BISS0001 gather signal and amplify process, then adds the rpyroelectric infrared signal processing circuit that a small amount of outward element forms passive type.The circuit theory of human body infrared monitoring modular as shown in Figure 2.
CC2430 is the novel concept a new generation ZigBee wireless singlechip family chip released after wireless singlechip company of chip giant TI corporate buyout CHIPCON.Zigbee protocol stack has been bound on the basis of CC2420, has had the RAM of 128 kB flash memory able to programme and 8 kB and some other function, under reception and emission mode, current loss is respectively lower than 27 mA or 25 mA.Its antijamming capability is strong, effectively can avoid flase alarm, good reliability, its cost is lower, power consumption is lower, functional
RE200B is multiple, be arranged on the car door of vehicle, vehicle window angle, its vehicle-mounted spacing is between two between 30cm-50cm, blocks according to passenger the ultrared different sequential that its adoptor sends before sensor, judge that passenger gets on the bus or gets off by micro controller system, as shown in Figure 4.When people gets off time then this order of blocking conversely, the pulse sequence that VO produces is contrary, and signal is delivered to micro controller system STATUS register and carried out subtracting counting, and micro controller system then recalculates the effective strength in compartment and adds up and preserve.
Control module utilizes the seating capacity preset in micro controller system, when the number of getting on the bus exceedes setting value, micro controller system sends locking passenger vehicle command signal, and after being driven by LM324, delivers to the electronic lighter of Control passenger vehicle, locking passenger vehicle actuating unit, passenger vehicle cannot be started, and show current persons count with LED, data to be displayed is converted into binary-coded decimal and exports, show on LED after digital pipe display circuit adopts 74LS373 common cathode decoder driver to drive conversion, as shown in Figure 6.System is reported to the police by loud speaker simultaneously, and by CC2430, alarm message wireless remote is sent to passenger vehicle administrative center, and as shown in Figure 5, the P0.1 port of CC2430 is connected with the 2nd pin VO of BISS0001 chip by a resistance.When module monitors is to when having a physical activity, VO exports high level, otherwise is all low level.The IO external interrupt function of the P0.1 mouth of configuration CC2430, when having rising edge pulse to arrive, external interrupt wakeup, carries out corresponding data processing, and data is issued combinator.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
