In a specific embodiment of the utility model, after being connected the box body between control computer 100 and the lamps and lanterns branch road, the trouble sets up personnel, for example the cell-phone that mr held sends the trouble setting instruction to car light system fault setting and fault detection device through the bluetooth, at this moment, the RTC can generate a time at random as the input digit of random generation function procedure, 1-5, 5 output digits can be exported to the random generation function simultaneously, and give relay control procedure as the input with these figures, and according to the break-make of input control relay. The range of the numbers output by the random generation function program is 1-5, and the numbers 1, 2, 3, 4 and 5 can be used as input to the relay control program to respectively control the on-off of the corresponding relays 1, 2, 3, 4 and 5.
For example, the utility model discloses relay 2 that sets up in the device of embodiment is normally open relay, and relay 1, relay 3, relay 4, relay 5 that set up are normally closed relay, and RTC generates digit 2, 3, 4. At this time, the MC9S12XS128 controls the relay 2, the relay 3 and the relay 4 to change the on-off states, namely the relay 2 is closed, the relays 3 and 4 are opened, and therefore the circuit has a short-circuit fault of a lamp branch where E19/2 is located and a disconnection fault of a lamp branch where E21 is located. At the moment, the alarm lamp is turned on, the horn makes a dripping sound, and the vehicle lamp system fault setting and fault detection device sends a fault point to the mobile phone through the Bluetooth.
A detector, such as a student, firstly observes that the E19/1 lamp is on and the E19/2 lamp is not on, can judge that the relay 1 and the relay 2 are in a closed state, and the on-off state of the relay 5 cannot be determined. At the moment, students can measure the detection holes K5 and K8 through an ohmic gear of a multimeter, and when the resistance of the relay 5 is detected to be 0, the relay 5 is closed. The E21 lamp is not bright, can't confirm the on-off state of relay 3, 4, and the student accessible universal meter voltage shelves measure inspection hole K3, K7, and the voltage that detects between inspection hole K3, K7 is 0, and this explains that relay 3 breaks off, measures inspection hole K4, K7 through universal meter ohm shelves, and the resistance that detects relay 4 is the infinity, explains that relay 4 breaks off.
After the student determines the relay to open and close, the fault can be cleared through the key module. In an embodiment of the present invention, after inputting a key number through the number key and confirming the inputted key number through the confirmation key, the control module 50 may compare the key-inputted number with a reference number of the relay controlled after receiving the fault setting instruction, and if they are consistent, the control module 50 controls the fault clearing module 40 to clear the fault and controls the fault indicating module 20 to terminate the fault indication; otherwise, the fault clearance fails, and the control module 50 continues to control the fault indication module 20 to indicate the fault.
Taking the above experimental example as an example, the set fault is that the relay 2 is closed, the relays 3 and 4 are opened, at this time, a student can input 2, 3 and 4 key numbers through the numeric keys, then, after pressing the confirmation key to confirm the input key numbers, the MC9S12XS128 can compare the key numbers 2, 3 and 4 input by the numeric keys with the numbers 2, 3 and 4 of the corresponding relay labels generated by the RCT, and by comparing the two numbers to be consistent, the MC9S12XS128 can control the relay 2 to restore the open state, and the relays 3 and 4 to restore the closed state, so as to clear the short-circuit fault of the lamp branch where the E19/2 is located and the open-circuit fault of the lamp branch where the E21 is located, and control the alarm lamp to be turned off, and the dripping sound of the horn disappears.
