when the vehicle has a fault, the first driving unit 1 drives the turn lamp group 3 to flicker; when the first driving unit 1 fails and the isolator 4 is disconnected, the second driving unit 2 drives the turn light group 3 to flicker.
In this embodiment, the first driving unit 1 is a master alarm system; the second drive unit 2 is a standby alarm system.
The alarm redundancy device is specifically divided into the following three working conditions:
the first operating condition is: when the vehicle normally runs, the devices on the vehicle are all supplied with power through the generator 6, the first driving unit 1 and the second driving unit 2 are also all supplied with power through the generator 6, but the second driving unit 2 is not started at the moment.
The second operating condition is as follows: the first drive unit 1 drives the turn lamp group 3 to blink when the vehicle malfunctions.
The third operating condition: when the line on the first driving unit 1 is in fault and the isolator 4 is disconnected, the second driving unit 2 drives the turn lamp group 3 to flicker.
Through the arrangement of the first driving unit 1 and the second driving unit 2, when the vehicle has a fault, the first driving unit 1 can drive the turn light group 3 to flicker so as to remind the vehicles to go and go of the fault; when the first driving unit 1 has a fault, the turn lamp group 3 can be driven to flicker by the standby second driving unit 2, so that the vehicle is reminded of the fault of the vehicle.
Wherein, referring to fig. 2, the first driving unit 1 includes: a first power supply 11 and a driving module 12;
the negative pole of the first power supply 11 is grounded, and the positive pole of the first power supply 11 is connected with the generator 6;
the driving module 12 is configured to drive the turn light set 3 to blink, an input end of the driving module 12 is coupled to a connection point between the first power source 11 and the generator 6, and an output end of the driving module 12 is connected to the turn light set 3. The driving module 12 is a conventional turn signal driving circuit, and will not be described herein.
Wherein, referring to fig. 2, the second driving unit 2 includes: a second power supply 21, a controller 22, and a flash relay 23;
the negative pole of the second power source 21 is grounded, and the positive pole of the second power source 21 is coupled with the connection point of the first power source 11 and the generator 6 through the isolator 4;

the first operating condition is: during normal vehicle operation, the isolator 4 is in a closed state, and the generator 6 supplies power to the entire vehicle's equipment, including the first power source 11 and the second power source 12.
The second operating condition is as follows: when the vehicle has a fault, the driving module 12 drives the turn light group 3 to flash to remind the coming and going vehicles to avoid the fault because the priority level of the driving module 12 is higher than that of the controller 22.
The third operating condition: when a fault occurs in a circuit where the driving module 12 is located, for example, a short circuit fault occurs in a circuit where the generator 6 and the first power source 11 are located, the isolator 4 may be disconnected, and a fault in a circuit where the driving module 12 is located may specifically cause the isolator 4 to be disconnected. When a circuit where the driving module 12 is located breaks down and the isolator 4 is disconnected, the driving module 12 cannot drive the turn light set 3 to flicker, meanwhile, the second power supply 21 supplies power to the controller 22, the controller 22 sends an enabling signal to the flash relay 23, and after the flash relay 23 receives the enabling signal output by the controller 22, the turn light set 3 is controlled to flicker at a certain frequency so as to achieve the purpose of reminding a vehicle of coming and going.
In this embodiment, when the circuit where the driving module 12 is located fails, the turn signal lamp set 3 may be driven by the flash relay 23, so as to implement the setting of the standby alarm system; and through the flash relay 23, the standby alarm can be realized at lower cost and with smaller change amount by directly adding one flash relay 23 without changing the internal program of the controller 22 or the driving module 12 in the whole alarm system.

In this implementation, the turn signal lamp group 3 includes left back turn signal lamp and right back turn signal lamp, and all is provided with first input interface and second input interface, two mutually independent power source on left back turn signal lamp and the right back turn signal lamp.
When the driving module 12 works normally, the power is supplied to the turn light set 3 through the first input interface to complete the corresponding action instruction, and when the flash relay 23 receives the enabling signal to work, the power is supplied to the turn light set 3 through the second input interface to complete the corresponding action instruction.
Referring to fig. 2, the alarm redundancy device further includes a first fuse 51, a second fuse 52, and a third fuse 53;
the first fuse 51 is used for protecting the driving module 12, one end of the first fuse 51 is coupled to a connection point of the first power source 11 and the generator 6, and the other end of the first fuse 51 is connected to the driving module 12;
the second fuse 52 is used for protecting the flash relay 23, one end of the second fuse 52 is coupled to a connection point of the second power supply 21 and the isolator 4, and the other end of the second fuse 52 is connected to an input terminal of the flash relay 23;
