Abstract
The utility model discloses a portable automotive exhaust gas detection device. The portable automotive exhaust gas detection device comprises a singlechip, a photoionization detector, a touch screen, a power supply and an alarm device, wherein the photoionization detector, the touch screen, the power supply and the alarm device are respectively connected with the singlechip; and the power supply is used for supplying electricity to the system by using a lithium battery. According to the device, the ATMEGA48 singlechip and the photoionization detector are used as cores, so that the device is small in size, low in power consumption, high in reliability and convenient in detecting and use.
Description
Technical field
The utility model relates to a kind of gas-detecting device, a kind of concentration that can show real-time detection vehicle exhaust in time, accurately, reliably particularly, and the portable automobile exhaust pick-up unit of reporting to the police according to the warning concentration of setting.
Background technology
Environmental pollution is serious day by day thereupon, dischargings such as sulphuric dioxide to each equipment have also proposed new standard, wherein also comprise the detection to vehicle exhaust, because automobile flows, therefore a lot of the detection also needs to detect in the on-fixed place, and the instrument volume of traditional detection vehicle exhaust is bigger, and power consumption is lower, has influenced quality and the efficient of the testing of vehicle exhaust.
The utility model content
The technical matters that the utility model solves is to provide that a kind of volume is little, low in energy consumption, reliability is high, detects portable automobile exhaust pick-up unit easy to use.
For solving the problems of the technologies described above, the utility model has adopted the portable automobile exhaust pick-up unit, comprise single-chip microcomputer, photoionization detector, touch-screen, power supply and warning device, described photoionization detector, touch-screen, power supply and warning device are connected single-chip microcomputer respectively, and it is system's power supply that described power supply adopts lithium battery.
Be connected with the single channel amplifier between described photoionization detector and the single-chip microcomputer, described single channel amplifier is MAX4240.
Described warning device is light emitting diode, loudspeaker and vibrating device.
The beneficial effect that the utlity model has: it is core that device adopts ATMEGA48 single-chip microcomputer and photoionization detector, and volume is little, low in energy consumption, reliability is high, detects easy to use.This device is provided with the gas preference pattern, can detect the vehicle exhaust constituent concentration exactly; Simultaneously can realize quantitative detection; This device sensitivity height can detect the existence of the gas that is low to moderate ppm concentration.This device makes the testing place of vehicle exhaust more flexible, and detection time is more permanent, has improved quality and the efficient of testing.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Portable automobile exhaust pick-up unit as shown in Figure 1, comprise single-chip microcomputer, photoionization detector, touch-screen, power supply and warning device, photoionization detector, touch-screen, power supply and warning device are connected single-chip microcomputer respectively, and it is system's power supply that power supply adopts lithium battery.
It is core that this device adopts with ATMEGA48 single-chip microcomputer and photoionization detector, the composition-individual system that possesses multinomial functions such as data acquisition, keyboard operation, demonstration as a result, and system adopts lithium battery power supply, the portability of implement device.
Single chip computer AT MEGA48 is highly integrated microprocessor, adopts the 32-TQFP encapsulation, and profile is small and exquisite, conserve space, low energy consumption.Simultaneously, built-in 10 A/D converters satisfy the A/D conversion accuracy of system fully.Adopt single chip computer AT MEGA48 can save an A/D converter; ROM and RAM, the portability of pick-up unit is improved in shared space that like this can reduction system.
This pick-up unit also adopts light emitting diode, toy trumpet and vibrating device to form simple and practical alarm unit, when detecting vehicle exhaust concentration and exceed preset value, sends acousto-optic and vibration alarming like this, in time reminds the user.
Photoionization detector in the pick-up unit is output as the current value of 4～20mA, has therefore added-individual current/voltage-converted part at the A/D of single-chip microcomputer translation interface front end.MAX4240 is a single channel amplifier, and is low in energy consumption.Add MAX4240 in the circuit and both current signal can be converted to voltage signal, again the undesired signal in the trap signal effectively.
Pick-up unit adopts lithium battery that system is powered, and for safe, stable power supply, the charging of assurance device, guarantees that device can detect the concentration of vehicle exhaust in time, accurately and rapidly.This part is mainly become with MAX7824 power supply chip master by MAXl837.MAX7824 becomes 15 V voltages with the 24V voltage transitions, and this is because photoionization detector needs the 15V power supply.MAXl837 is to be 3.3V voltage with 15 V voltage transitions, mainly powers to single-chip microcomputer.
