Detailed description of the invention
In order to allow those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, the utility model has disclosed a kind of safety of school bus device, comprises middle control unit, the power supply unit and the display unit that are connected with middle control unit, the counting sensing unit being connected with middle control unit.
Counting sensing unit can be responded to the people who gets on and off, and information can be sent to middle control unit to count, and the people that gets on the bus counts and adds up 1, and the people's counting of getting off subtracts 1.And by display unit, number is shown.
As shown in Fig. 2 ~ 5, safety of school bus device is also provided with the annunciator unit being connected with middle control unit.Annunciator unit comprises and being connected with ignition lock ACC and middle control unit respectively, and be connected with annunciator optocoupler.
In the time that vehicle is flame-out, middle control unit detects flame-out signal by ignition lock ACC and annunciator optocoupler, when counting now (also has delay personnel) while being not 0 on car, just can realize warning, as the mode of glimmering by annunciator LED lamp is sent prompting to driver.
