Abstract
The utility model discloses a vehicle-mounted gas alarm which is characterized by comprising a detector host, an acousto-optical alarm state display circuit, a self-check fault alarm circuit and a power supply circuit, wherein the detector host is composed of a gas sensing probe and an alarm signal processing circuit; the detector host is powered by a vehicle-mounted battery and connected in series with a PPTC (polymeric positive temperature coefficient); when in alarm, the detector host sends an alarm signal to the acousto-optical alarm state display circuit integrated with a display panel through a positively-connected diode (D1); a drive circuit drives an LED (light emitting diode) (D2) and a speaker (BL) to send an acousto-optical alarm; the display panel is provided with an alarm clear switch (K1) and connected with the acousto-optical alarm state display circuit; the alarm clear switch (K1) is pressed to clear the alarm; the display panel is provided with a fault detection switch (K2); the fault detection switch (K2) is connected with the detector host; and when pressed, the detector host generates an analog alarm signal and sends an analog acousto-optical alarm.
Description
Technical field
The utility model relates to vehicle carried device technical field, particularly relates to a kind of vehicle-mounted gas alarm that places in the car body.
Background technology
Demand along with the surging and energy-conserving and environment-protective of oil price; Combustion gas is as a kind of new power energy resource, special in the city the increasing alternative fuel that becomes gasoline, diesel, its advantage is very obvious; Both reduced the expense of going of unit mileage; Satisfied the discharge-ring guaranteed request again widely, now in each big city this oil to change the vehicle of gas very universal, but also in constantly increasing.Owing to use combustion gas instead as power source, combustion gas belongs to a kind of inflammable, explosion hazard gases, and daily vehicle ' just becomes a matter of great account feelings with the safe handling of parking combustion gas in the process; Accidents caused for fear of leaking, at aspects such as the technical indicator of gas cylinder and burning line and fitting operations relevant technical standard is arranged all, let leakage accident generation probability drop to minimum; Because the impact during the vehicle ' motion, with the increase of the mileage that goes, the possibility of leakage also can increase; Each accident all is heavy and grieved, how can monitor the leakage in the car at any time, solves problem the primary stage of leaking; With regard to a kind of warning device that is suitable for vehicular of urgent demand, can remind the driver in time to handle dangerous situation timely, add safety curtain again one for driving; The existing market to the vehicle-mounted gas warning device also seldom; What have also is function singleness, and operation inconvenience awaits and technology upgrading.
Summary of the invention
In order to solve the existing problem of background technology, the utility model provides a kind of vehicle-mounted gas alarm, has multiple type of alarm, can in time remind the driver to make measure, has ensured occupant's life security.
The utility model is to adopt following technical scheme: a kind of vehicle-mounted gas alarm; It is characterized in that it comprises detector main frame, sound and light alarm status display circuit, self check failure alarm circuit, feed circuit, the detector main frame is made up of combustion gas inductive probe and alerting signal treatment circuit; The detector main frame is supplied power by vehicular power-bottle, on the circuit there is from recovering insurance resistance string; During warning, the detector main frame through the diode that just is being connected to the sound and light alarm status display circuit of display panel one in send alerting signal, driving circuit drives light emitting diode and loudspeaker send sound and light alarm; Display panel is provided with the alarm release switch, and the alarm release switch links to each other with the sound and light alarm status display circuit, presses the alarm release switch and removes warning; Display panel is provided with the fault detect switch, and the fault detect switch is connected with the detector main frame, presses the fault detect switch, and the detector main frame produces the simulation alerting signal, sends the simulation sound and light alarm; The one duty indication diode that links to each other with the detector main frame is arranged on the display panel, be used for indicating operating status.
Described vehicle-mounted gas alarm is characterized in that described detector main frame is installed in the position that is easy to generate gas leakage in the pilothouse respectively, and in the trunk of deflation flask, display panel is arranged on the interior operator's console of pilothouse.
Described vehicle-mounted gas alarm is characterized in that on the described combustion gas inductive probe dust cover being arranged, and dust cover is surrounded by gas-permeable nets.
The utility model is simple and practical, has self-checking function, and is safe and reliable, can give the alarm at the leakage initial stage, removes dangerous situation, ensures occupant safety.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The utility model embodiment comprises detector main frame, sound and light alarm status display circuit, self check failure alarm circuit, feed circuit shown in accompanying drawing, the detector main frame is made up of combustion gas inductive probe and alerting signal treatment circuit; The detector main frame is supplied power by vehicular power-bottle, and string has from recovering insurance resistance PPTC in supply line, protects automatically if any the overload phenomenon during work, and overload is got rid of the back and recovered automatically; During warning; The detector main frame detect gas leakage through the diode D1 that just is being connected to the sound and light alarm status display circuit of display panel one in send alerting signal; Driving circuit drives light emitting diode D2 and loudspeaker BL send sound and light alarm, remind driver and crew in time to remove the dangerous condition; Display panel is provided with alarm release K switch 1, and alarm release K switch 1 links to each other with the sound and light alarm status display circuit, presses alarm release K switch 1 after dangerous situation is got rid of and removes warning; Whether display panel is provided with fault detect K switch 2, and fault detect K switch 2 is connected with the detector main frame, presses fault detect K switch 2, and the detector main frame produces the simulation alerting signal, sends the simulation sound and light alarm, can operate as normal in order to daily testing circuit; The one duty indication diode D3 that links to each other with the detector main frame is arranged on the display panel, be used for indicating operating status; The detector main frame is installed in the position that is easy to generate gas leakage in the pilothouse during installation, and in the trunk of deflation flask, display panel is arranged on the interior operator's console of pilothouse.In order to adapt to interior environment; Prevent the influence of dust to the combustion gas inductive probe, can on the combustion gas inductive probe, install dust cover additional, dust cover is surrounded by gas-permeable nets; Structure is a labyrinth-like resistance dirt structure; When this stops dust, do not influence the circulation and the testing result of air, prolong the serviceable life of combustion gas inductive probe.
This specific embodiment has two kinds of type of alarms of acousto-optic, and is simple in structure, has overload protection function, has self-checking function, can in time remind the personnel of driving to make measure during gas leakage, ensured driver and passenger's personal safety.
During enforcement against shock rubber washer and damping spring can also be set on casing, vibrations are to the damage of electronic unit when avoiding vehicle movement.
A plurality of detector main frames can also be set during enforcement, and a shared display panel shows and warning on display panel along separate routes.
Be merely the utility model embodiment in sum, all modification according to the equivalence that the application did all is regarded as the utility model technology category.
