Embodiment
To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with drawings and the specific embodiments, to this
Application is described in further detail.For the sake of simplicity, eliminate that well known to a person skilled in the art some skills in being described below
Art feature.
As shown in Figure 1, the present embodiment provides a kind of safety belt cheating system based on iButton2, including safety belt lock
Button 4 and the safety belt lock tongue 1 with 4 Matching installation of safety belt lock catch, further include：
Bus- Speed Monitoring module, the module include the speed inductor being electrically connected with the microprocessor of automobile ECU, speed sensing
Device is used for the speed for detecting vehicle；
Passenger detection module, the module can only include the first pressure sensing being electrically connected with the microprocessor of automobile ECU
Device, first pressure sensor are arranged on seat, microprocessor by pressure value that first pressure sensor detects come
Judge on seat whether someone；The module can also include second pressure sensor, and second pressure sensor is arranged on safety belt
On band body, microprocessor judges seat by two pressure values that first pressure sensor and second pressure sensor detect
On whether someone, detection it is more accurate；
IButton signal generating modules, as shown in figure 3, the module includes the iButton2 being arranged on safety belt lock tongue 1
With the 1-Wire interface circuits 3 being arranged on safety belt lock catch 4.The anti-cheating system includes two iButton signals and mould occurs
