Abstract
The invention discloses a system for monitoring concentration of carbon monoxide and carbon dioxide in an automobile compartment. A single chip microcomputer PICl6F877A is taken as a control core, the concentration of the carbon monoxide and the concentration of the carbon dioxide are transmitted to the single chip microcomputer via a carbon monoxide sensor and a carbon dioxide sensor, whether the concentration of the carbon monoxide or the concentration of the carbon dioxide exceeds a preset value or not is judged by the single chip microcomputer via logic operation, and if the concentration of carbon monoxide or the concentration of the carbon dioxide exceeds the preset value, sound-light alarm is sent, an executing part is controlled to adjust to enable the concentration of the carbon monoxide or the concentration of the carbon dioxide to be decreased to be smaller than the preset valve, carbon monoxide concentration poisoning or carbon dioxide concentration poisoning is effectively prevented, and safety persons in the automobile compartment is guaranteed.
Description
Technical field
The present invention relates to gas monitoring system, particularly a kind of realize to automobile bodies carbonic oxide and gas concentration lwevel accurately, fast, monitoring and the monitoring system of early warning in real time.
Background technology
In some cases---as cold and airtight car door and vehicle window; Or the adult leaves, and child is locked in or forgets in car---can be because automobile bodies be airtight or motor exhaust is revealed as in the compartment, and cause the interior carbonic oxide of car or gas concentration lwevel to exceed standard and the tragedy that meets accident.
Summary of the invention
The invention provides and a kind ofly effectively reduce that carbonic oxide in the car or gas concentration lwevel exceed standard and incidence, function admirable, the reliability height of the tragedy that meets accident are applicable to carbon-monoxide concentration and gas concentration lwevel monitored control system in the various automobile bodies.
For solving the problems of the technologies described above, the present invention adopts automobile bodies carbonic oxide and gas concentration lwevel monitoring system, it is characterized in that: comprise sensor, the constant temperature sample circuit, amplifying circuit, the A/D change-over circuit, micro controller system, the control cock circuit, display unit, communication circuit and acoustic-optic alarm, described sensor connects the constant temperature sample circuit, amplifying circuit connects the constant temperature sample circuit, the A/D change-over circuit connects amplifying circuit, described A/D change-over circuit, the control cock circuit, display unit, communication circuit is connected micro controller system respectively with acoustic-optic alarm, and described sensor is carbon-monoxide concentration sensor and gas concentration lwevel sensor.
Described micro controller system adopts PICl6F877A.
The beneficial effect that the present invention has: this system serves as the control core with micro controller system PICl6F877A, by carbon-monoxide concentration sensor and gas concentration lwevel sensor carbon-monoxide concentration in the automobile bodies and gas concentration lwevel are passed to micro controller system, micro controller system judges by logic operation whether carbon-monoxide concentration or gas concentration lwevel surpass setting value, if surpass then send sound and light alarm, and carry out fenestration procedure by the control execution unit, carbon-monoxide concentration or gas concentration lwevel are reduced to below the setting value, effectively prevent carbon-monoxide concentration poisoning or carbon dioxide poisoning, guarantee occupant's safety.This system not only can real-time analysis, handle processing data, can also preserve related data simultaneously, start and report to the police and send data, realizes the purpose of remote monitor and control by communicating circuit.Because vehicle operating or personnel just can be that carbon-monoxide concentration is poisoned or gas concentration lwevel continues to increase in the compartment in the compartment, so can not report, open by mistake the vehicle window situation by mistake.
Description of drawings
Fig. 1 is structured flowchart of the present invention.
The specific embodiment
Automobile bodies carbonic oxide and gas concentration lwevel monitoring system are mainly shown display circuit and communication circuit etc. and are formed by constant temperature sample circuit, amplifying circuit, A/D change-over circuit, sound light alarming circuit, control cock circuit, liquid as shown in Figure 1.Adopt the core component of micro controller system PICl6F877A construction system, according to sensor and measurement signal, realized the measurement of concetration to carbonic oxide and titanium dioxide, when carbonic oxide and titanium dioxide concentration greater than setting threshold, will send sound and light alarm, thereby start the control cock circuit, open vehicle window, make car ventilation and reduce carbonic oxide and dense carbon dioxide, avoid the occupant to meet accident.
Sensor is made up of carbon-monoxide concentration sensor and titanium dioxide concentration sensor, and it act as volume fraction with carbonic oxide and carbon dioxide and changes into the corresponding simulating voltage signal and come out.During use, the adjustment of sensitivity is very important, for the sensitivity that makes sensor is enough high, at first will calibrate these two sensors, guarantees that precision changes in certain scope, if not in this scope, then explanation need be regulated.And the adjusting of sensitivity relies on regulating load resistance to realize.By regulating load resistance, the concentration value of demonstration is consistent as far as possible with actual value.Can determine the resistance of load resistor like this.
In order to ensure the sensitivity of checking system, need to guarantee that the temperature of sensitive member is steady state value, must adopt the feedback control system of closed loop, system adopts the thermostatic control sample circuit.
The concentration value that arrives when system acquisition is during greater than concentration threshold, and system starts sound and light alarm, opens vehicle window simultaneously, makes car ventilation and reduces carbonic oxide and dense carbon dioxide, avoids the occupant to meet accident.
This system at set intervals to two concentration value collections once, the analog quantity concentration data that collects is deposited in the data memory, Single Chip Microcomputer (SCM) system will be finished periodically detecting concentration, the A/D that carries out of concentration value is changed, dynamically show the concentration value that collects, according to display density with preestablish threshold value and compare, surpass preset value if monitor concentration, start sound light alarming circuit, and unlatching vehicle window, and output signal sent by communicating circuit, realize the purpose of remote monitor and control.
