At above-mentioned prior art, the applicant has done positive and useful design, and technical scheme described below produces based on this prerequisite
Summary of the invention
The purpose of this utility model is to provide a kind of junked-auto air bag trigger, and it has improved security and reliability that air bag is disassembled, uses simple, convenient.
The purpose of this utility model reaches like this, a kind of junked-auto air bag trigger, it is characterized in that, comprise the power supply detection module, the input detection module, the delay adjustments module, the output alarm module, ignite coil module and state display module, the power supply detection module, the input detection module, the delay adjustments module, the output alarm module is connected successively step by step with the ignition coil module, the input termination external power source of power supply detection module, to flow to the input detection module from the detected qualified voltage of external power source, the output of igniting coil module transmits detonator signal to the outside, state display module and power supply detection module, input detection module and ignition coil module connect.
In a specific embodiment of the present utility model, described state display module comprises four road indicator lamps, is respectively applied for demonstration " power connection ", " voltage is qualified ", " preparing to ignite ", " ignition " four kinds of duties.
In another specific embodiment of the present utility model, described input detection module comprises the preparation button, presses the preparation button, and system enters the ignition SBR; Unclamp the preparation button, system's emergency power off.
In another specific embodiment of the present utility model, described output alarm module comprises firing button, when the preparation button of input detection module is in down state, presses firing button, and system enters blasting state; Unclamp firing button, system's emergency power off.
In another specific embodiment of the present utility model, described external power source is a low-tension supply.
Also have in the specific embodiment of the present utility model, the indicator lamp in the described state display module is LED.
More of the present utility model and in specific embodiment, described output alarm module adopts buzzer to report to the police.
The utility model is owing to adopted said structure, need press the preparation button in the input detection module earlier, press the firing button in the output alarm module again, air bag just can be detonated like this, and in the whole ignition process, prepare button and firing button and all need be in down state.If be in an emergency midway, prepare button or firing button as long as unclamp, external power source promptly can be cut off, and ignites promptly to stop, thereby has improved security and reliability that air bag is ignited, disassembles for the safety of air bag and lays a good foundation.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
Fig. 2 is the guidance panel schematic diagram of an embodiment of the present utility model.
The specific embodiment
In order to make the public can fully understand technical spirit of the present utility model and beneficial effect; the applicant will describe in detail the specific embodiment of the present utility model below in conjunction with the accompanying drawings; but the applicant is not restriction to technical scheme to the description of embodiment, anyly makes form but not the variation of essence all should be considered as protection domain of the present utility model according to the utility model design.
A kind of junked-auto air bag trigger, comprise power supply detection module 1, input detection module 2, delay adjustments module 3, output alarm module 4, ignite coil module 5 and state display module 6, power supply detection module 1, input detection module 2, delay adjustments module 3, output alarm module 4 and ignition coil module 5 are connected successively step by step.The input termination external power source of power supply detection module 1 will flow to input detection module 2 from the detected qualified voltage of external power source.The output of igniting coil module 5 transmits detonator signal to the outside.State display module 6 is connected with power supply detection module 1, input detection module 2 and ignition coil module 5.Described input detection module 2 comprises the preparation button, presses the preparation button, and system enters the ignition SBR; Unclamp the preparation button, system's emergency power off.Described output alarm module 4 comprises firing button, when the preparation button of input detection module 2 is in down state, presses firing button, and system enters blasting state; Unclamp firing button, system's emergency power off.Described state display module 6 comprises four road indicator lamps, is respectively applied for demonstration " power connection ", " voltage is qualified ", " preparing to ignite ", " ignition " four kinds of states, and in the present embodiment, described indicator lamp is LED.
Please consult Fig. 1 again and, operation principle of the present utility model and operating procedure are described in conjunction with Fig. 2.On guidance panel shown in Figure 2, be provided with two buttons, the button that is marked as " preparation " promptly is to prepare button, the button that is marked as " ignition " promptly is a firing button, also be provided with four LED lights in addition, be marked as " power supply ", " voltage ", " preparation " and " ignition " respectively, be respectively applied for demonstration " power connection ", " voltage is qualified ", " preparing to ignite " and " ignition " four kinds of duties.When needs were enabled trigger, at first the input with power supply detection module 1 was connected to external power source, and described external power source is a low-tension supply, can adopt rechargable power supplies or dry cell, and is safe and reliable.In the present embodiment, adopted rechargable power supplies, supply voltage is 12V.In case trigger is connected external power source, " power connection " indicator lamp in the state display module 6 is bright.When supply voltage value is in the setting range interval, be qualified voltage, allow for back level module for power supply, at this moment, " voltage the is qualified " indicator lamp in the state display module 6 is bright.When supply voltage was lower than air bag and reliably ignites voltage, " voltage is qualified " indicator lamp extinguished, and expression rechargable power supplies voltage is on the low side, need charge.After qualified voltage was input to input detection module 2, system was in wait state, and this moment, whether system was pressed at detection preparation button all the time, if press, illustrated that then the operating personnel will carry out air bag and ignite.For the reliability and the security that improve ignition, system is designed to: if prepare firing safety air-bag, then prepare button from start to finish and all require to be pressed, if unclamp, then fortuitous event appears in explanation, and system is with emergency power off.Be pressed if prepare button, then " preparing to ignite " indicator lamp in the state display module 6 is bright, and trigger is started working, and detects automatically.Simultaneously, input detection module 2 passes to delay adjustments module 3 with information, carries out delay adjustments, and in the present embodiment, time delay was set to 2～4 seconds.After the time-delay, be in down state all the time if prepare button, then information is admitted to output alarm module 4, in this module, carries out audible alarm by buzzer, requires the operating personnel to confirm whether will ignite air bag.When buzzer sounded, the expression staff can press firing button, and in the present embodiment, the buzzing time of buzzer is about 4 seconds.If the operating personnel confirms to want firing safety air-bag, then during the buzzer buzzing, press firing button, ignition information is delivered to ignites coil module 5.To buzzer buzzing end, to ignite coil module 5 and start detonator signals, air bag begins to ignite, and " ignition " indicator lamp is lighted at this moment, and this indicator lamp is lighted always in the ignition process.After air bag is ignited and finished, unclamp and prepare button and firing button.In whole ignition process, prepare button and firing button and need be in down state simultaneously, as long as arbitrary button is released, system all thinks and emergency occurred, meeting emergency cut-off power supply, make to ignite to stop, having improved security and reliability that air bag is ignited so greatly, disassemble for safety and lay a good foundation
