Description
Technical field
The utility model relates to safety of school bus field, particularly relates to oxygen content monitor and early warning system in a kind of school bus car.
Background technology
Along with developing rapidly of China's economy and improving constantly of living standards of the people, automobile pollution constantly rises, and safety of school bus also more and more receives the concern of people.In recent years there occurs a lot of children to neglect because of teacher, be retained on school bus, due to school bus airtight space, children are trapped on school bus for a long time, and in car, oxygen content in air reduces, and finally causes children to be suffocated.This is a defect of current school bus design.Therefore, exploitation one can oxygen content in Real-Time Monitoring school bus, and when oxygen content is lower than a certain setting value, initiatively can take measures and the device given the alarm, and the safety of school bus is more had to the meaning of reality.
Utility model content
The utility model, for above-mentioned prior art Problems existing, proposes oxygen content monitor and early warning system in a kind of school bus car, solve the inner oxygen level of above-mentioned existing school bus low time can not carry out in time warning the problem that rescue causes security incident.
The technical scheme that the utility model provides is: oxygen content monitor and early warning system in a kind of school bus car, it is characterized in that, comprise: single-chip microcomputer, the lambda sensor being arranged on school bus inside, the alarm being arranged on school bus outside and Vehicular accumulator cell, described Vehicular accumulator cell connects the power input of described single-chip microcomputer, the output terminal of described lambda sensor connects the I/O input end of described single-chip microcomputer, an I/O output terminal of described single-chip microcomputer connects described alarm, and another I/O output terminal of described single-chip microcomputer connects the control end of the glass-frame riser of school bus.
Further, described single-chip microcomputer adopts Freescale S12 model single-chip microcomputer.
Further, described lambda sensor adopts concentration difference cell type lambda sensor.
Further, described alarm adopts acoustic-optic alarm.
The beneficial effects of the utility model: oxygen content monitor and early warning system in the school bus car that the utility model provides, by lambda sensor and Single-chip Controlling, the monitoring and warning of oxygen content in school bus car can accurately be carried out, this circuit system is simple, cost is low, function is strong, dependable performance, by Automatic control of single chip microcomputer alarm and glass-frame riser, there is higher intelligent level.
Accompanying drawing explanation
Fig. 1 is oxygen content monitor and early warning system theory diagram in this practical school bus car.
Embodiment
The utility model is further described with specific embodiment below in conjunction with meeting.
See Fig. 1, it is oxygen content monitor and early warning system structural drawing in a kind of school bus car that the utility model proposes.
As shown in Figure 1, oxygen content monitor and early warning system in this practical school bus car, comprise: single-chip microcomputer, the lambda sensor being arranged on school bus inside, the alarm being arranged on school bus outside and Vehicular accumulator cell, described Vehicular accumulator cell connects the power input of described single-chip microcomputer, the output terminal of described lambda sensor connects the I/O input end of described single-chip microcomputer, an I/O output terminal of described single-chip microcomputer connects described alarm, and another I/O output terminal of described single-chip microcomputer connects the control end of the glass-frame riser of school bus.
Power supply of the present utility model is Vehicular accumulator cell, and be that single-chip microcomputer is powered by Vehicular accumulator cell, not needing increases power supply in addition, inner by school bus is its power supply, and structure is simple, is directly powered by Vehicular accumulator cell, when the engine is not in operation, also can work on.
Further, described single-chip microcomputer adopts Freescale S12 model single-chip microcomputer.
Further, described lambda sensor adopts concentration difference cell type lambda sensor.
Further, described alarm adopts acoustic-optic alarm.
In the utility model embodiment, by the lambda sensor being arranged on school bus inside, the content of oxygen in air in car is detected, and testing result is sent in single-chip microcomputer; First single-chip microcomputer sets alarm value X1 and dangerous values X2, single-chip microcomputer judges the voltage signal that lambda sensor sends, when oxygen content value is less than alarm value X1, illustrate that oxygen content in car in air is lower than normal air oxygen level, single-chip microcomputer sends control information activation alarm, carries out sound and light alarm; When oxygen content value is less than dangerous values X2, illustrate that the oxygen content of the air in car is low to moderate the level that people can be made to suffocate, now, Single-chip Controlling glass-frame riser is fallen, and air in car is communicated with car outer air, improves the oxygen content of air in car.
In the present embodiment, conventional simple judgement only done by single-chip microcomputer.
Oxygen content monitor and early warning system in the school bus car that the utility model provides, by lambda sensor and Single-chip Controlling, the monitoring and warning of oxygen content in school bus car can accurately be carried out, this circuit system is simple, cost is low, function is strong, dependable performance, by Automatic control of single chip microcomputer alarm and glass-frame riser, there is higher intelligent level.
Above the utility model is described in detail, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also makes a variety of changes under the prerequisite not departing from the utility model aim.Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
