Brief description of the drawings

Fig. 1 is system construction drawing of the present utility model；

Fig. 2 is control system circuit figure.

Specific embodiment

The following is a specific embodiment of the present utility model, the utility model is described further in conjunction with accompanying drawing.

As shown in figure 1, a kind of motor bus car door safe and intelligent open system, including smog detects circuit with fuel gas 10th, temperature collection circuit 20, microcontroller 30, control execution circuit 40, warning circuit 50；Smog detects circuit with fuel gas 10 and temperature collection circuit 20 be connected with the input of microcontroller 30, the output end of microcontroller 30 and control execution circuit 40 are connected with warning circuit 50；The Real-time Collection of microcontroller 30 in-car smog and fuel gas, temperature information, carry out logic and sentence It is disconnected, when wherein there are data to exceed the dangerous critical value for setting, car door is automatically opened up by controlling execution circuit 40, while starting Alarm.

Microcontroller 30 is using the STC single-chip microcomputers with AD conversion function.Smog includes with fuel gas detection circuit 10 Smog and fuel gas detection sensor and the comparator being attached thereto；Smog uses MQ-2 types with fuel gas detection sensor Sensor gathers smog and fuel gas information, and comparator uses OP07 type comparators.Temperature collection circuit 20 is passed including temperature Sensor, temperature sensor uses DS18B20 type sensors.Control execution circuit 40 include photoelectrical coupler and be attached thereto or Door chip, photoelectrical coupler uses EL817 type photoelectrical couplers, OR gate chip to use SN74LVC1G32DCKR type OR gate chips.

As shown in Fig. 2 the direct current signal that 4 pin (6 pin) output of MQ-2 changes with smokescope, is turned by potentiometer CR1 3 pin that voltage signal is sent to comparator OP07 are turned to, potentiometer CR2 constitutes the threshold voltage of comparator, can according to sensitivity To be adjusted setting, when smog, imflammable gas concentration are higher, when the output voltage of MQ-2 is higher than threshold voltage, comparator Output low level (0v), the now bright alarms of LED, while the P10 pins for triggering microcontroller STC15F2K60S2 start AD conversion, The direct current signal that MQ-2 is exported is converted into data signal, data processing and logic judgment is carried out, if numerical value is more than default Dangerous critical value just to control performing module send low level (enabling signal), while start buzzer warning remind driver with Passenger；When the output voltage of concentration reduction sensor is less than threshold voltage, comparator upset output high level (Vcc), LED L1 extinguishes, and STC microcontrollers are not AD converted, and saves electric energy.Wherein R1 seals in the heating circuit of sensor, can protect and add Heated filament from it is cold electric when impact.

Meanwhile, temperature collection circuit selects digital temperature sensor DS18B20, as shown in Fig. 2 Real-time Collection vehicle interior temperature Information, digital information is transferred directly to the P15 pins of microcontroller STC15F2K60S2, and single-chip microcomputer is patrolled according to default value Collect and judge, if temperature is higher than critical value, just send low level (enabling signal) to control performing module, while startup buzzer Alarm.

When microcontroller STC15F2K60S2 judges the smog and fuel gas value or temperature value of collection more than default During dangerous critical value, low level is exported by P20 pins, enabling signal is sent to car door opening performing module.Low level is sent to The input pin Input of photoelectrical coupler EL817, photoelectrical coupler conducting, output pin Output exports high level to OR gate 5 pins of chip SN74LVC1G32DCKR, 1 pin of OR gate chip SN74LVC1G32DCKR opens the door with the button of driver and believes Number connection, either photoelectrical coupler output high level enabling signal or driver button enabling signal it is effective when, 6 pin Co of OR gate chip export high level enabling signal, are sent in original door control system.Thus can effectively keep away Exempt from the situation generation that driver's reason causes car door to open, while nor affecting on the normal opening door operation of driver.

The above, is not to do other forms to the utility model only to preferred embodiment of the present utility model Limitation, any those skilled in the art changed possibly also with the technology contents of the disclosure above or change form for The Equivalent embodiments of equivalent variations.But, it is every without departing from the utility model plan content, according to technology reality of the present utility model Verify any simple modification made for any of the above embodiments, equivalent variations and remodeling, still fall within protection domain of the present utility model.
