In signal input module circuit, in the time that vehicle normally moves, car speed on off state is 1, and while stopping, state is 0; After vehicle ignition, ignition lock state is 1, and flame-out rear state is 0; Car door shuts, and door contact interrupter state is 1, otherwise is 0; Parking Brake tension, its on off state is 1, releasing orientation is 0.The state being made up of four kinds of switches has 16 kinds, wherein has 12 kinds to be the state that needs warning, and 4 kinds is normal condition.Specifically as shown in table 1.
The state that signal conversion circuit is reported to the police 12 kinds of needs is integrated into 8 kinds of alarm condition, shows respectively by alarm code 0,1,2,3,4,5,6,7.Concrete corresponding relation is as shown in table 2.Signal conversion point three kinds of situations: 1. every kind of corresponding a kind of alarm code of alarm condition; 2. many kinds of alarm condition are integrated into a kind of warning and code demonstration; 3., when vehicle-state is normal, do not need display alarm.
Table 2
The effect of signal input module circuit resistance is in the time that input switch disconnects (state is 0), guarantees that decoder 9 input end A/B/C/D are high level.As shown in table 2, when state of motion of vehicle switch 7, ignition lock 6, door contact interrupter 5, when Parking Brake switch 4 disconnects, four on off states are 0000, the D of decoder 9, C, B, the input of A pin is high level 1111, 15 pin output low levels of decoder 9, be after vehicle parking stops working, car door does not close, Parking Brake unclamps, warning device sends reports to the police and display alarm code 0, seven segment digital tubes 15 display alarm codes 0, Coding and driving display chip 14 input ends all should be low level, owing to showing the A of Coding and driving chip 14, B, C pin connects respectively coder 10 output pin A0, A1, A2 pin, so require tripod all to should be low level, coder 10 input low levels are effective, now input pin Y7 should be 0, decoder 9 pin Y15 are connected with coder 10 input pin Y7 and can realize signal conversion object.
As shown in table 2, in the time that state of motion of vehicle switch 7, ignition lock 6, door contact interrupter 5, Parking Brake switch 4 assembled state are respectively 1000/1001/1010/1011, input pin D, the C of decoder 9, B, A pin level are 0111/0110/0101/0100, be after car stops working, automobile is in running state, slip car, decoder 9 output pin Y7, Y6, Y5, Y4 are low level, and at this moment warning device sends and reports to the police and display alarm code 4.While there is low level, all should to make coder 10 pin Y3 be low level for decoder 9 output pin Y7, Y6, Y5, Y4 as shown in Table 2.The Y4 pin of decoder 9, Y5 pin, Y6 pin, Y7 pin are connected with Y03 pin, Y13 pin, Y23 pin, the Y33 pin of door 12 with the second input respectively, the Y3 pin of the output termination coder 10 of the second input and door 12, in the time that wherein an input pin is low level, coder 10 pin Y3 are low level.
As shown in table 2, when state of motion of vehicle switch 7, ignition lock 6, door contact interrupter 5, Parking Brake switch 4 states are 0110/0111 o'clock, the input pin D of decoder 9, C, B, A pin level is 1001/1000, its output pin Y9, Y8 output low level, the state of vehicle is that car door shuts, Parking Brake unclamps/strains, stop and light a fire, this is a kind of normal ignition state, do not need to report to the police and show failure code, therefore need to allow seven segment digital tubes 15 in extinguishing state, this function realizes by the pin RBI zero setting that shows Coding and driving chip 14, as decoder 9 output pin Y9, RBI zero setting when Y8 output low level.
Other states are realized similar above-mentioned three kinds of situations.
Alarm display module is by showing that Coding and driving chip 14, seven segment digital tubes 15, ann test circuit 16 and warning circuit 17 form, and supreme when 5 dozens of switch SW, charactron shows 8, and buzzer phone rings, and realizes alarm buzzer, charactron speed measuring function.SW5 beat to lower time, realized normal alarm code Presentation Function, was realized and was switched on or switched off audible alarm circuit by the RBI of 74LS48.
The status real time monitor of this detailed description of the invention to automobile, when occur vehicle slip car, do not shut car door while travelling, do not unclamp Parking Brake, do not shut after igniting car door, do not strain a series of abnormal condition such as Parking Brake after flame-out, device can send alarm and corresponding demonstration in time, provide against hidden trouble, improve vehicle and pedestrian's safety.
