Abstract
The utility model discloses an automobile harmful gas alarm. After a gas sensor detects excess harmful gas, a controlling circuit controls an alarm circuit to send out sound and light and give out alarm via a testing circuit, controls an electric window open and controls the engine out, and the occupants can furthermore trigger a burglar alarm to send out distress signal when the occupants are fainted.
Description
The utility model relates to a kind of cab warning, and the interior pernicious gas content overproof of particularly a kind of automobile bodies is reported to the police and controlled the device that its content continues rising.
Present air-conditioned coach, for improving refrigeration (heat) efficient, door and window closes.During engine operation, waste gas always has in the compartment that partly bleeds.Parking state particularly, driving engine is in the idling work state, and the traction compressor load strengthens, fuel oil is in the uncomplete combustion state, particularly CO content is higher for waste gas content, adds that vehicle is in halted state, and air can't convection current, exhaust gas concentration constantly gathers rising in the compartment, CO wherein particularly, because its colorless and odorless, human body occur poisoning back non-evident sympton and slowly falling into a comatose state, finally cause casualty accident, this kind tragedy occurs repeatedly.
By retrieval, the patent No. is that 89216479 patent has proposed a solution, and its principle of work mainly is to detect carbon-monoxide concentration by gas sensor to exceed standard, and the control warning circuit sends sound and light alarm, and control electromagnetic valve is opened air inlet valve simultaneously.But still there are some defectives in this scheme: 1, the air-conditioned coach air inlet valve is difficult to open with electromagnetic valve at present, can't realize.Even if opened air inlet valve, under the Parking state, also can't realize ventilation.2, no specific product organization plan.
The purpose of this utility model provides a kind of automobile harmful gas annunciator, its when not only pernicious gas exceeds standard in the compartment may command electric window open automatically, when the Parking state, disconnect the engine ignition circuit and make engine off, also can connect burglar alarm and send an SOS in case stupor appears in the occupant.
The utility model is realized as follows: gas sensor, control circuit, timing reset circuit, electrical controller, sound light alarming circuit have constituted warning device to harmful gas jointly.
When the detected harmful gas concentration of gas sensor surpasses permissible value (preestablishing), its conductivity changes thereupon, after detecting, testing circuit is conveyed to control circuit, the guide sound optical alarm circuit sends alerting signal, control electrical controller simultaneously electric window is opened, as then controlling engine off at the Parking state.If stupor appears in the occupant, after warning, do not press reset button in several minutes, then trigger burglar alarm and send strong sound and light alarm in the hope of assistance.
Even if the utility model has the advantages that occupant's poisoning goes into a coma, because injunction engine off, ended the further generation of pernicious gas, opening vehicle window simultaneously ventilates, make harmful gas concentration reduction in the compartment, also can touch burglar alarm and send strong sound and light alarm, send an SOS to the stranger and sue and labour.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is an option A principle of work block scheme.
Fig. 2 is option A installation site scheme drawing in car.
Fig. 3 is the option b outside drawing.
Fig. 4 is an option b principle of work block scheme.
As Fig. 1, harmful gases such as CO, the HC in 1 pair of automotive exharst gas of gas sensor, NO are all responsive, after concentrations build-up arrives to a certain degree, its electrical quantity changes, testing circuit 2 detects this variation and when relatively reaching preset value, send instruction to control circuit 3, control circuit 3 guide sound optical alarm circuits 4 send sound and light alarm, control electrical controller 5 simultaneously, present embodiment adopts the two keys relay adhesive, positive voltage is through 6 ends that wherein a contact flows to and the automatic window master cock is joined, and the control automatic window is opened; 7 ends connect parking brake lamp positive terminal, the positive voltage of 7 ends flows to another relay 8 by another contact and makes it adhesive during the Parking state, relay 8 normally closed contact two ends 9,10 are connected in the engine ignition circuit, and 9,10 ends just disconnect when relay 8 adhesives, force engine off.11 are the time delay circuit that resets, and when pressing reset button 12 in Preset Time, control circuit 3 is removed and reported to the police and recovery; When exceeding Preset Time and do not press the button 12, the time delay circuit 11 that resets sends energizing signal by 13 ends to the burglar alarm that is attached thereto.
As Fig. 2, warning box 14 is installed on showy, the position smoothly of instrument desk, and the outer element of dotted line among built-in Fig. 1: the part in gas sensor 1, reset button 12 and loudspeaker, the lamp, dotted line places in the control capsule 15, is placed in the automative wiring storehouse, is convenient to wiring.
