Description
Affiliated technical field:
The utility model relates to a kind of alcohol sensor and control system, especially can monitor alcohol concentration in the operator's compartment automatically and to the intelligence that start-up system the is implemented necessary control protective system of driving when intoxicated.
Background technology;
The known alcohol sensor-based system that is used for traffic is to be made of alcohol sensor, control and data processing circuit and display system at present.During use, tested personnel must exhale to exhaust tube by mouth, could start measuring system.This system is difficult to use in to the automatic monitoring of alcohol with to the control of vehicle launch system.In addition, alcohol sensor is very responsive to the variation of temperature and humidity.The gas of being breathed out from mouth is not enough to influence the reliability of result of a measurement, but the temperature and humidity variation range in the operator's compartment is very big, makes this alcohol sensor-based system to use.
Summary of the invention;
In order to overcome the deficiency of existing alcohol sensor-based system, it is a kind of to alcohol monitoring and realize temperature and humidity is changed the intelligence that the compensates protective system of driving when intoxicated automatically that the utility model provides.
The utility model provides a kind of intelligence protective system of driving when intoxicated, and it is characterized in that; This protective system mainly is made of an alcohol sensor (3), temperature and humidity sensor (5), a microprocessor (6) and a semiconductor relay (7); Alcohol sensor (3) and temperature and humidity sensor (5) join with microprocessor (6) respectively, and microprocessor (6) connects automobile initiating means by relay (7).
The utility model intelligence is driven when intoxicated in the protective system, can also set up a fan (2) and a pneumatic sensor (4); Fan (2), alcohol sensor (3), pneumatic sensor (4) and temperature and humidity sensor (5) common apparatus have in the probing shell of guard net (1) in one; The power supply of fan (2) links to each other with the control electric power system of automobile, and pneumatic sensor (4) connects microprocessor (6); Wherein probing shell is preferably tubular.
The utility model intelligence is driven when intoxicated in the protective system, and described microprocessor (6) can also link to each other with a green LED indicator lamp (8), a yellow led indicator lamp (9), a red LED indicator lamp (10) respectively.
The drive when intoxicated working process of protective system of the utility model intelligence is, the fan that strengthens airiness is installed in the dead ahead of sensor, and the power supply of fan is connected in the control electric power system of locomotive.When locomotive enters the startup readiness, fan begins to start, and the Continuity signal of pneumatic sensor output that is contained in the alcohol sensor rear is given microprocessor, thus the start-up control program, and green indicating lamp is bright.Microprocessor is found out corresponding safe alcohol sensor higher limit according to the temperature and humidity data that record in data bank, and itself and measured alcohol signal are compared.If the signal that records is less than the maximum safe limit value, microprocessor is exported a control signal and is given relay, and then makes the vehicle launch system enter mode of operation; If the signal that records is greater than the maximum safe limit value, relay is given in microprocessor output one signal beyond target, and the vehicle launch system can not work; Red indicating light is bright.If fan is not worked or flowed into the airflow obstruction of alcohol sensor, pneumatic sensor will export a high resistant signal to microprocessor, and yellow indicator lamp is bright.
In the utility model, alcohol sensor is sampling and supervision alcohol concentration automatically, temperature and humidity sensor are monitored automatically to ambient temperature and humidity, and microprocessor is handled and compensated the data that record, and by relay starting current are carried out control according to its result.The employing of microprocessor can be adjusted the setting of the alcohol safe concentration upper limit by Control Software easily and not need circuit is done any change or debugging.To the measurement of ambient temperature and humidity, the data handing of microprocessor reaches the compensation to ambient temperature and humidity variation by immediately for temperature and humidity sensor.
In a word, the protective system sampling of need not exhaling of driving when intoxicated of the utility model intelligence, microprocessor is monitored automatically, has overcome the error that environmental difference causes, and the vehicle launch system is carried out automatic guidance.The accident that can prevent from effectively to drive when intoxicated takes place.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the intelligence program control principle flow chart of protective system of driving when intoxicated.
The specific embodiment:
The utility model structure as shown in Figure 1; among the figure, 1 guard net, 2 fans, 3 alcohol sensors, 4 pneumatic sensors, 5 temperature and humidity sensor, 6 microprocessors, 7 semiconductor relays, 8 green LED indicator lamps, 9 yellow led indicator lamps, 10 red LED indicator lamps, 11 connect vehicle startup system, 12 and connect automobile control electric power system.
Guard net (1) is to be used for protection probe and fan (2), and prevents the unexpected injury of fan (2) to human body.In addition, also can play the effect of air filter.The fan (2) that strengthens airiness is installed in the dead ahead of sensor, and the power supply of fan (2) is connected in the control electric power system (12) of locomotive.When locomotive enters the startup readiness, fan begins to start, and the Continuity signal of pneumatic sensor (4) output that is contained in alcohol sensor (3) rear is given microprocessor (6), thus the start-up control program, and green indicating lamp (8) is bright.Microprocessor is found out corresponding safe alcohol sensor higher limit according to the temperature and humidity data that temperature and humidity sensor (5) record in data bank, and itself and measured alcohol signal are compared.If the signal that records is less than the maximum safe limit value, microprocessor is exported a control signal and is given semiconductor relay (7), and then makes vehicle launch system (11) enter mode of operation; If the signal that records is greater than the maximum safe limit value, semiconductor relay (7) is given in microprocessor output one signal beyond target, and vehicle launch system (11) can not work; Red indicating light (10) is bright.If fan (2) is not worked or flowed into the airflow obstruction of alcohol sensor (3), pneumatic sensor (4) will export a high resistant signal to microprocessor (6), and yellow indicator lamp (9) is bright.
