1. A monitoring system for a bus, wherein the bus has a plurality of passenger seats, each of the plurality of passenger seats has a seat and a seat belt connected to a buckle received in a lock, the monitoring system comprising:
a plurality of presence sensors adapted to detect a presence of passengers respectively in the plurality of passenger seats;
a plurality of belt sensors adapted to detect a fastening of the respective seat belts in the plurality of passenger seats;
a central processing unit (CPU) that receives signals from said plurality of presence sensors and the plurality of belt sensors;
a human-machine interface (HMI) connected to said CPU so as to provide information on a status of said plurality of presence sensors of said plurality of belt sensors;
a plurality of slaves, wherein each slave of said plurality of slaves is connected to at least one presence sensor of said plurality of presence sensors and to at least one belt sensor of said plurality of belt sensors, wherein each slave has a transducer that receives signals from the at least one presence sensor and from the at least one belt sensor so as to interpret a status of the at least one presence sensor and the at least one belt sensor;
a plurality of branch cables connected said plurality of slaves to at least one connection cable, the at least one connection cable adapted to be disposed in a lateral wall of the bus, the at least one connection cable transmitting signals from said plurality of slaves;
a master comprising said CPU, said master connected to the at least one connection cable so as to receive the signals from said plurality of slaves and to send the signals to said HMI by a network cable, wherein the at least one connection cable is a flat bipolar cable having a negative pole and a positive pole coated with an insulating sheath, the insulating sheath formed of a thermoplastic elastomer; and
a plurality of T-branch electrical connectors that connect said plurality of branch cables to the at least one connection cable, wherein each belt sensor of said plurality of belt sensors is adapted to be installed in the lock of the seat belt so as to detect an insertion of the buckle in the lock, wherein each belt sensor of said plurality of belt sensors has a microswitch that is mechanically controlled by the buckle, the microswitch being normally open or normally closed, the microswitch being connected to one of the plurality of slaves by an electrical cable.
