Description
Technical field: the utility model belongs to automobile intelligent monitoring field, relates to a kind of automobile integrated alarm device.
Background technique: at present along with development of economic construction, the automotive industry technology also develops rapidly, particularly Automobile Design at intelligent, automobile electrical appliances at high speed development aspect integrated, miniaturization, the high reliability, traditional auto alarm has been not suitable for Hyundai Motor development and needs, exists the not high problem of integrated degree.
Summary of the invention: the utility model is in order to solve the not high problem of the integrated degree of traditional alert device, propose a kind of automobile integrated alarm device, it is characterized in that: described alarm comprises single-chip microcomputer and does not close warning circuit and low pressure alarming circuit by monolithic processor controlled safety strip cue circuit, water-temperature water-level warning circuit, filament testing circuit, car door.This automobile integrated alarm device is made central control system by single-chip microcomputer; the automobile water temperature is too high, water level is low excessively, car light does not close, whether filament intact, the lamp wiring short-circuit protection; the grade of safety strip prompting is integrated together carries out detection alarm to the working state of automobile; make the driver find fault in advance; overhaul, be applicable to Hyundai Motor intellectuality, miniaturization, integrated requirement.
Description of drawings: Fig. 1 is the electrical principle block diagram of the utility model automobile integrated alarm device;
Fig. 2 is that the filament of the utility model automobile integrated alarm device detects schematic diagram;
Fig. 3 is that the water level of the utility model automobile integrated alarm device just detects schematic diagram.
Embodiment: this automobile integrated alarm device comprises single-chip microcomputer and does not close warning circuit and low pressure alarming circuit by monolithic processor controlled safety strip cue circuit, water-temperature water-level warning circuit, filament testing circuit, car door.As shown in Figure 1, its electrical principle filament detects, warning, low pressure alarming and water-temperature water-level several parts of reporting to the police are not closed in safety strip prompting, car door, is specially:
When filament detects, when position lamp, braking light switch closure or disconnection, by level conversion, shaping, provide a signal to CPU, the CPU basis is to Stop Lamp, position lamp, filament, electric current or resistance detection, export a control signal, the control triode drives the filament tutorial light by triode and carries out alarm.
The safety strip prompting; The switching signal of ignition lock provides a switching signal through the level conversion shaping to CPU, and CPU is according to control signal of switching signal output, and control safety strip tutorial light glimmers.
Car door does not close warning: when ignition lock is in the ON shelves, and the door contact interrupter closure, car door does not close, CPU reports to the police according to the signal that door contact interrupter provides, the control buzzer call, sound fundamental frequency is in accordance with regulations reported to the police, and the fundamental frequency that car door does not close alarm sound is 800～2000KHZ.
Low pressure alarming: the switching signal of low pressure alarming sensor is given CPU through photoelectricity isolation, shaping, input signal, and CPU reports to the police according to the height control buzzer sound fundamental frequency in accordance with regulations of incoming signal level, and the fundamental frequency of low pressure alarming sound is 1.0 ± 0.1KHZ.
Water-temperature water-level is reported to the police: the transducing signal of water-temperature water-level sensor is through bleeder circuit, provide a comparison signal to hysteresis comparator, relatively exporting a control signal to voltage comparator is that high level or low level are given CPU, CPU is according to control signal of input signal output, control buzzer sound fundamental frequency is in accordance with regulations reported to the police, and the fundamental frequency of water-temperature water-level alarm sound is 2.6 ± 0.5KHZ.
The filament of this alarm damages and detects principle as shown in Figure 2: when position lamp switch K disconnects, if bulb is good, then+5V voltage meets diode D4 to position lamp L1 by resistance R 35, ground connection then, because the resistance of bulb is very little, the resistance of resistance R 35 is very big, and the base voltage of triode T10 is 0, triode T10 ends, and the A point is a high level; Damage as bulb, then have+5V voltage can't form the loop with ground after meeting diode D4 by resistance R 35, make triode T10 conducting, the A point is a low level.Singlechip CPU is judged the quality of bulb by detecting the variation of A point high-low level.
When position lamp switch K connects, if bulb is good, then meet high-power wire-wound resistor R27 through K switch, output termination low pressure loss diode D9 by supply voltage, again through recovering safety fuse cutout F1 ground connection behind the load bulb L1, because the resistance of resistance R 27 is less, produce the pressure drop of about 0.3V on it, through reducing 0.4V again behind the diode D7, triode T7 conducting, supply voltage arrives resistance R 28, resistance R 29 back ground connection through triode T7, triode T8 conducting, and the B point is a low level; If bulb damages, supply voltage meets high-power wire-wound resistor R27 through K switch, exports termination low pressure loss diode D9, can recover can't constitute the loop with ground behind the safety fuse cutout F1, there is not pressure drop on the resistance R 27, triode T7 ends, and causes triode T8 to end, and the B point is a high level.Singlechip CPU changes by the level that detects B point height, judges the bulb quality.
Water level is crossed low detection principle as shown in Figure 3: when water tank lacks water, it is maximum that level sensor R6 resistance reaches, and 2 pin of voltage comparator U1 are exported high level to triode T1, T3, triode T1, T3 conducting than 3 pin voltage height; The A point is a low level, and the water-level alarm tutorial light is bright simultaneously.When water was full, it is minimum that level sensor R6 resistance reaches, and 2 pin of voltage comparator U1 are lower than 3 pin voltages, output low level triode T1, T3, triode T1, T3 conducting; The A point is a high level, and the water-level alarm tutorial light goes out simultaneously.Whether singlechip CPU changes by the level that detects A and order, judges whether lack of water of water tank, and control the built-in buzzer of alarm and pipe.
This automobile integrated alarm device adopts U.S.'s peace general (AMP) connector assembly.Too high to the automobile water temperature, water level is low excessively, air pressure is low excessively, whether car door closes, ignition lock closes and car light does not have pass, Stop Lamp, position lamp open filament, each working state of line short is monitored in real time, the flicker of control safety strip warning light, safety strip is pointed out, utilize the built-in buzzer of alarm, according to monitoring state, export different alert frequencies by single-chip microcomputer, alarm indicator lamp on the Control of Automobile instrument panel uses acoustooptic alarm in time to remind the driver to keep in repair simultaneously.Utilize single-chip microcomputer, voltage comparator, Charge Coupled Device, resettable fuse, low pressure loss diode, buzzer detects the working state of automobile, in case break down and during misoperation, the buzzer call alarm indicator lamp is bright, reminds the driver in time to discharge fault.
