Abstract
The utility model discloses a detection device used for detecting untight a closing situation of a car door of a car. The detection device used for detecting the untight closing situation of the car door of the car comprises a car door detection circuit, and is characterized by further comprising a single-chip microcomputer, an alarming signal circuit and a power source, wherein the car door detection circuit, the anti-impact alarming signal circuit and the power source are respectively connected with the single-chip microcomputer. The detection device used for detecting the untight closing situation of the car door of the car is simple and convenient to operate, good in practicability, and strong in stability, and has the advantages of being simple in structure, convenient to install, and long in service life.
Description
Technical field
The utility model relates to field of automobile safety, relates in particular to the not tight detecting device of a kind of automobile door closing.
Background technology
Along with the quick increase of China's automobile pollution, various potential safety hazards will appear in the thing followed.Such as, automobile may not closed tight because of arrangements for automotive doors when running at high speed, and causes member in the car to have under the situation of lateral acceleration at turn inside diameter or change etc. and drop out from car, causes traffic accident.Under these circumstances, the utility model proposes a kind of dry-reed tube that uses and detect the device whether arrangements for automotive doors is closed tight, improve passenger's the safety of taking.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile door closing not tight detecting device, can guarantee chaufeur and passenger's safety of life and property.
In order to realize above-mentioned technical assignment, the utility model adopts following technical scheme to be achieved:
The not tight detecting device of a kind of automobile door closing comprises the car door testing circuit, also comprises micro controller system, circuit and power supply, and wherein car door testing circuit, collision-proof alarm signal circuit, power supply link to each other with micro controller system respectively.
The utility model also has the other technologies characteristics:
Described micro controller system is the 89C51 micro controller system.
Described car door testing circuit is realized by dry-reed tube MKA-3.
The utility model compared with prior art has following technological merit:
1, this device is easy and simple to handle, and practicality is good, and stability is strong;
2, this device has characteristics such as simple in structure, easy for installation, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the circuit diagram of car door testing circuit of the present utility model.
Fig. 3 is work journey figure of the present utility model.
Below in conjunction with the drawings and specific embodiments particular content of the present utility model is described in further detail.
The specific embodiment
1, principle of work of the present utility model is as follows:
Principle of work of the present utility model is as follows: the P1.0 of 51 micro controller systems links to each other with the car door testing circuit, at car door the corresponding car door column of dry-reed tube is installed corresponding magnet is installed, when door shutting, dry-reed tube enough closely makes dry-reed tube connect apart from the distance of magnet, this moment, the passenger can take safely, need not report to the police to occupant and chaufeur; When car door was not fastened, dry-reed tube can not make dry-reed tube connect from the distance of magnet, and produce interrupt signal at the INTO of 51 micro controller systems mouth this moment.After 51 micro controller systems receive interrupt signal, send alerting signal to warning circuit, remind chaufeur and car door passenger car door not to close tight.
2 hardware design
Hardware configuration of the present utility model as shown in Figure 1.
Hardware of the present utility model mainly is made up of 89C51 micro controller system, car door testing circuit, collision-proof alarm signal circuit 3 parts.The each several part function is specific as follows:
1) the 89C51 micro controller system plays a part key as hardcore of the present utility model, and main effect is after the interrupt signal that detects the INTO mouth, sends alerting signal to warning circuit, reminds chaufeur and car door passenger car door not to close tight.
2) dry-reed tube of the present utility model need be used MKA-3, general common little dry-reed tube is when no magnetic force or can not intercept voltage (especially being welded by flatiron) fully, sensitive inadequately, must be very close to just adhesive of magnet, so a common terminating resistor connects ground (or 5v source) again, the connection that the other end is made delivery port is very unreliable, and the greatly and common filling with inert gas not of big dry-reed tube volume is sensitive inadequately.So the utility model adopts sensitive dry-reed tube, sensitive dry-reed tube is external transistor switching circuit again, and voltage signal is effectively intercepted and conducting, and is very reliable.Be illustrated in figure 2 as the circuit diagram of car door testing circuit of the present utility model.
3) with the audio-signal-driven loud speaker of P1.4 output 1KHz and 500Hz, make alerting signal, require the 1KHz signal to ring 100ms, the 500Hz signal rings 200ms, hockets, and the P1.7 mouth connects a switch and controls, when the switch alerting signal of closing is sent sound, stop when switch disconnects warning signal, coding is with the function that realizes knocking into the back and reporting to the police.This switch will replace with the key switch of automobile, and this cover system can normal operation in motion to guarantee automobile.1) the P1.4 port in " Single Chip Microcomputer (SCM) system " zone is wired on the SPKIN port in " audio frequency amplification module " zone; 2) the SPK OUT port in " audio frequency amplification module " zone connects the loudspeaker in 8 Europe.
3 job procedure
Job procedure of the present utility model is as follows: when detecting the interrupt signal of INTO mouth, send alerting signal to warning circuit, remind chaufeur and car door passenger car door not to close tight; When not detecting the interrupt signal of INT0 mouth, will not report to the police.The diagram of circuit of its program respectively as shown in Figure 3.
Claims (3)
1. the not tight detecting device of automobile door closing comprises the car door testing circuit, and it is characterized in that: also comprise micro controller system, circuit and power supply, wherein car door testing circuit, collision-proof alarm signal circuit, power supply link to each other with micro controller system respectively.
2. the tight detecting device of automobile door closing as claimed in claim 1, it is characterized in that: described micro controller system is the 89C51 micro controller system.
3. the tight detecting device of automobile door closing as claimed in claim 1, it is characterized in that: described car door testing circuit is realized by dry-reed tube MKA-3.
